Pengaruh Penggunaan Effective Microorganism 4 (EM4) Pada Budidaya Jamur Merang (Volvariella volvaceae) Menggunakan Media Tandan Kosong Kelapa Sawit. Andriyanto, Andriyanto Budiarti, Retni S Subagyo, Agus Empty Fruit Bunch EM4 Volvariella volvaceae Indonesia is the biggest producer of palm oil in the world. Palm oil empty fruit bunches is the biggest waste generated by the palm oil processing industry. However, utilization of the palm oil empty bunches has been not optimal. The palm oil empty fruit bunches have potential to be developed into a medium for growing mushroom because it has a high cellulose content. However, the high content of cellulose and lignin in palm oil empty fruit bunches is difficult to decompose into organic material that need for mushroom growth. The composting processes of empty fruit bunches can be increased by using Effective Microorganism (EM4). This study aims to understanding the role of Effective Microorganism 4 (EM4) on Volvariella volvaceae cultivation processes that used Empty Fruit Bunches compost. This research was conducted by composted the empty fruit bunch with different concentration of EM-4 there are 0%, 10%, 15%, 20% and 25%. Parameters observed were number of mushrooms, weight of mushrooms and C / N ratio of compost. The results showed that EM-4 had reduce C/N ratio of empty bunch palm oil compost, C/N ratio was not affected mushroom production and EM4 was affected mushroom production, the highest production reached by concentration of 15% that had not significant with concentration of 5%, 10% and 20%. At concentration of 25% mushroom production was decreased. It is probably there are several mechanisms by EM4 microorganisms containing that affected mushrooms production.  Universitas Andalas 2019-03-15 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://jbioua.fmipa.unand.ac.id/index.php/jbioua/article/view/257 10.25077/jbioua.7.1.59-68.2019 Jurnal Biologi UNAND; Vol. 7 No. 1 (2019); 59-68 Jurnal Biologi Universitas Andalas; Vol 7 No 1 (2019); 59-68 2655-9587 2303-2162 eng https://jbioua.fmipa.unand.ac.id/index.php/jbioua/article/view/257/219 Copyright (c) 2019 Jurnal Biologi Universitas Andalas

Agensi Hayati Jamur Endofit Daun dan Batang Apel Timor Ernawati, Ernawati Senari, Ana Maria Mellu, Yoristo Boimau, Milan antimikroba agensi hayati jamur endofit batang dan daun apel timor  ABSTRACTThis study discusses the antimicrobial potential and biological agents of the endophytic fungi on the leaves and stems of Timor apples. Apple plants have been developed in Timor Tengah Selatan (TTS) Regency; however, they slowly stop producing and even die due to disease. Disease control can be done through biological agents with endophytic fungi. This study aims to determine the antimicrobial activity and biological agency of endophytic fungi found in the stems and leaves of the Timor apple plant. This study uses a laboratory experiment method by testing the antimicrobial activity of the isolated endophytic fungi with the well method against E. coli and P. aeruginosa bacteria and C. albicans fungi. Biological agency against pathogenic fungi was tested using antagonist test. The inhibition and antagonist zone data were analyzed descriptively. The study results show that there were three isolates of endophytic fungi, namely IH isolate (black isolate) of Aspergillus sp., IA isolate (bluish green isolate) of Aspergillus sp., and IP isolate (white isolate) of Fusarium sp. Endophytic fungal isolates were found to have activity in inhibiting the growth of the test microbes, with the average inhibition zone of IH of Aspergillus sp. against C. albicans was 15.6 mm, IP of Fusarium sp against P. aeruginosa was 15.9 mm, and IA of Aspergilus sp against E.coli was 11.2 mm. The compound test shows that the endophytic fungal isolates contained alkaloids, terpenoids, and flavonoids. Meanwhile, the antagonist test shows that endophytic fungi were able to inhibit the growth of pathogenic fungi with the growth area coveredthe pathogenic fungus and the widest area was Aspergillus sp.Keywords: antimicrobial, biological agents, endophytic fungi, stems and leaves of Timor apples Universitas Andalas 2023-04-03 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article EKSPERIMENTAL application/pdf https://jbioua.fmipa.unand.ac.id/index.php/jbioua/article/view/399 10.25077/jbioua.11.1.22-28.2023 Jurnal Biologi UNAND; Vol. 11 No. 1 (2023); 22-28 Jurnal Biologi Universitas Andalas; Vol 11 No 1 (2023); 22-28 2655-9587 2303-2162 eng https://jbioua.fmipa.unand.ac.id/index.php/jbioua/article/view/399/278 Copyright (c) 2023 Jurnal Biologi UNAND

Keanekaragaman Vegetasi Pada Habitat Yang Terinvasi Tumbuhan Invasif Di Hutan Kota Bukit Langkisau Painan, Sumatra Barat Sehati, Dika Putri Solfiyeni, Solfiyeni Plant invasive urban forest composition structure diversity index Tumbuhan Invasif The presence of invasive plants in a habitat will cause significant disturbances, especially in decreasing the abundance of biodiversity. The high competitiveness of invasive species causes native species to lose in competition. Invasive species have spread in many places, one of which is in the Bukit Langkisau City Forest. However, data on the types of weeds and vegetation types in the habitats invaded by weeds in the Bukit Langkisau City Forest are not yet available. Vegetation analysis was carried out in the Bukit Langkisau Painan City Forest, West Sumatra. The study used a survey method by laying out plots by purposive sampling, which made 15 plots at each level of vegetation. The plot is 10 x 10 m for observation of tree-level vegetation, the plot is 5 x 5 m for sapling vegetation and for understorey vegetation the plot is 2 x 2 m. The results of the vegetation analysis recorded 87 species of which there were 32 invasive species. The dominant families were found such as Fabaceae family, Meliaceae for tree level, Piperaceae for sapling level and Poaceae for understorey level. The highest Importance Value Index for tree vegetation, sapling and understorey was found in the invasive species Swietenia macrophylla (IVI = 44.69%), Piper aduncum (IVI = 85.08%), and Imperata cylindrica (IVI = 33.67%). The Vegetation Diversity Index in the Bukit Langkisau City Forest is the tree level (1.90), sapling (1.26) and understorey (1.78) which are all classified as moderate. KEYWORDSPlant invasive, urban forest, composition, structure, diversity index Universitas Andalas 2023-04-03 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://jbioua.fmipa.unand.ac.id/index.php/jbioua/article/view/408 10.25077/jbioua.11.1.29-38.2023 Jurnal Biologi UNAND; Vol. 11 No. 1 (2023); 29-38 Jurnal Biologi Universitas Andalas; Vol 11 No 1 (2023); 29-38 2655-9587 2303-2162 eng https://jbioua.fmipa.unand.ac.id/index.php/jbioua/article/view/408/280 Copyright (c) 2023 Jurnal Biologi UNAND

Butterflies play a significant role in the ecosystem, both in the pollination process and in the process of detecting environmental changes in the ecosystem. One alternate strategy for preserving biodiversity and natural resources while boosting a nation's economy is ecotourism. This study aims to investigate the perceptions and attitudes of local communities in West Sumatera regarding with butterflies and ecotourism. The study was conducted from February to March, 2023 by using two-page questionnaire developed to collect social information regarding with ecotourism and butterflies through in-depth interview with respondents who was currently living in West Sumatra. A total of 30 respondents (15 Male, 15 female) from various background were questioned. According to the survey’s findings, the majority of the population (93%) was passionate about protecting biodiversity and has extensive understanding of ecotourism and butterflies. Additionally, the majority of respondents (93%) mentioned that they would love to join Butterfly Watching Program. The respondents indicated that West Sumatera has a lot of ecotourism destinations. To draw visitors, a more sophisticated ecotourism program centered on beautiful wildlife and flora should be established.

Ekspolarasi dan Karakterisasi Morfologi Jamur Makroskopis di Kawasan Hutan Adat Bukit Selebu, Kabupaten Merangin beserta Klasifikasi Potensinya Menggunakan K-Nearest Neighbors Zuhri, Rozana Satria, Deni Karakterisasi morfologi Fungi Makroskopis K-Nearest Neighbors mikologi Fungi are one of Indonesia's potential natural resources which contain various benefits for human life. The existence of macroscopic fungi is not yet well known so that little information about the types and their benefits is known to local people. In fact, information about species of fungi is very important because fungi have economic value and are producers for the food and pharmaceutical sectors. Populations of macroscopic fungi can disappear due to climate change and environmental factors, therefore, it is necessary to collect data on the species of macroscopic fungi. One way to detect the species of fungus is to classify it based on the morphological characteristics of the fungus with K-Nearest Neighbor. The aim of this research is to explore and identify the morphological characteristics of fungi using K-Nearest Neighbor as a classifier found in the Bukit Selebu traditional forest area, Merangin Regency. It is hoped that the results of this research can be the first step in efforts to utilize fungi through further research. This research was carried out in the Bukit Selebu traditional forest area, Merangin Regency and identification continued at the Biology Laboratory of Merangin University. Then the data on the species of fungi found were analyzed using k-Nearest Neighbors (kNN). The results of this research are that there are 27 species of fungi found in the Bukit Selebu traditional forest area, Merangin Regency, consisting of 3 species of Ascomycota divisions and 24 species of Basidiomycota divisions. The K-Nearest Neighbor method is very good in classifying fungi through the extraction of morphological characteristics with the highest accuracy reaching 93%.

One of the ornamental plants is Aglaonema sp. known as Sri Rejeki. It is enjoyed as an ornamental plant in terms of leaf pattern. However, Aglaonema has harmful ectoparasites. The aim of this study was to determine and identify ectoparasites in Aglaonema plants using the Visual Encounter method, and to analyze the role and solutions for the presence of ectoparasites in Aglaonema. Research observations were carried out for approximately three weeks from April to May 2022. Six individuals Aglaonema were used as samples. Observation was done by using the visual encounter method which was carried out once a week in the morning, afternoon, and evening with a total of three time observations (15 minutes each) at each time. Measurement of abiotic factors includes temperature, humidity, and weather. The results were used to determine the important value index (IVI) and Shannon-Wiener Index (H’). All identified organisms were arthropods (insects). There were five identified families:  Pseudococcidae, Coccidae, Formicidae, Chironomidae, and Muscidae. Pseudococcidae and Coccidae were the insect families that are confirmed as ectoparasites for plants. The solution for prevention or termination of ectoparasite is by replacing the invaded plant away from healthy plants, removing the infected parts of plant, and/or placing refugia plant for habitat of ectoparasite’s natural enemies.   Universitas Andalas 2024-12-21 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Observation; Visual Encounter application/pdf https://jbioua.fmipa.unand.ac.id/index.php/jbioua/article/view/461 10.25077/jbioua.12.2.122-128.2024 Jurnal Biologi UNAND; Vol. 12 No. 2 (2024); 122-128 Jurnal Biologi Universitas Andalas; Vol 12 No 2 (2024); 122-128 2655-9587 2303-2162 eng https://jbioua.fmipa.unand.ac.id/index.php/jbioua/article/view/461/319 Copyright (c) 2024 Jurnal Biologi UNAND

Physical Growth and Sexual Maturation of Subsistence Population in Padaido Island Papua Rumayauw, Insos Batseba Ratnawati, Sita Kawulur, Elda Irma Jeanne Joice Adaptive respond Body height Body weight age at menarche human evolution Physical growth and sexual maturity are two important events in the childhood phase. Measurement and assessment of development of body size is the best ways to understand the adaptive respond when face enviromental challenges of the traditional population. Several populations show that girls and boys tend to show varying ages and rates of growth and sexual maturity. The aim of this study was to study the growth patterns of height, weight and age at menarche in children of the Biak tribe in the Padaido Islands Region, Biak Regency, Papua Province. Cross-sectional research was designed to the children consisting of 130 boys and 153 girls. In order to determine the age at menarche using the status quo method.  The growth curve was analyzed using the Generalized Linear Model for Location, Shape and Scale (GAMLSS) model and the age of menarche was analyzed using the Probit-GLM analysis. Although geographic condition of Padaido island was isolated, the infrastructure and sosioeconomic conditions were indequate, however the age at menarche of Padaido girls (13,2 years) was included in the same category as the age at menarche nationally. The physical growth curve (height and weight) for girls exceeds that of boys before and during menarche, then decreases after menarche. This pattern is in line with previous research that girls have a larger stature at puberty because they accumulate body fat in preparation for menarche and the development of secondary sex characteristics. The environmental challenges have implications for the limited availability of energy to regulate maximum skeletal growth achieved at a young age, while the development of fat mass is achieved more slowly after sexual maturity. This describes a shift that deviates from the normal growth and development of the body..

Pengaruh Benzil Aminopurin (BAP) terhadap Induksi Tunas dari Nodus anggrek Dendrobium mussauense Media, Media Noli, Zozy Aneloi BAP Dendrobium mussauense In vitro Nodus Tunas Fisiologi Tumbuhan Dendrobium mussauense has attractive flowers and potential as a parent of a hybrid orchid. The color of this species is cream with violaceous purple venations on the labellum. D. mussauense is an orchid species listed as vulnerable in IUCN. This species is not located in protected areas nor known to be conserved ex-situ. Clonal propagation is an important biotechnological tool for the conservation of orchids. Thin cell layer (TCL) is a micropropagation method using thin-sized explants that facilitate the diffusion of nutrients to tissues. This study examined induction shoot through two explant cutting techniques, namely TCL and non-TCL explant, at various concentrations of BAP. The non-TCL explant was more effective than the TCL explant in inducing the shoot of D. mussauense. The half-strength Murashige and Skoog (MS) medium supplemented with 0.9 mg.L-1 BAP was a suitable concentration to induce the shoot of D. mussauense through non-TCL explant. The average shoot length was 1,8 cm, and the average number of shoots was 5/explant.

Complementary Molecular Data for Two Species from Herbarium Bogoriense: Sphaerobolus stellatus and Trichaleurina javanica Yuliana, Meta Maulana, Indra Mulya, Sari Fusvita, Laifa Hermawan, Rudy A micro-mushroom namely Sphaerobolus stellatus (BO 24422) and macro-mushroom namely Trichaleurina javanica (BO 24420) were found in Landscape Arboretum of IPB University. The latest identification used morphological characteristic and molecular study of Large Subunit DNA marker respectively. According to their identification, the database of fungal identification is commonly from Internal Transcribed Spacer (ITS) marker for molecular study. But both specimens, S. stellatus BO 24422 and T. javanica BO 24420, have not the ITS sequences yet. This research aim to study the molecular data of two specimens using ITS sequences. The method of this research used the molecular identification using internal transcribed spacer (ITS) primer: ITS 4 as a forward and ITS 5 as a reverse. Two phylogenetic trees were generated by Randomized Axelarated Maximum Likelihood (RAxML) Black box. Bootstrap (BS) values ≥ 90% were displayed on the phylogenetic treebranches. The result showed that the bootstrap value for S. stellatus BO 24422  showed the good value as 96% classified as S. stellatus. Then, T. javanica BO 24420  had a better BS value with 93% classified as T. javanica. The ITS is a general marker and very useful for molecular identification.  Universitas Andalas 2024-04-24 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://jbioua.fmipa.unand.ac.id/index.php/jbioua/article/view/474 10.25077/jbioua.12.1.42-46.2024 Jurnal Biologi UNAND; Vol. 12 No. 1 (2024); 42-46 Jurnal Biologi Universitas Andalas; Vol 12 No 1 (2024); 42-46 2655-9587 2303-2162 eng https://jbioua.fmipa.unand.ac.id/index.php/jbioua/article/view/474/297 Copyright (c) 2024 Jurnal Biologi UNAND

Population Study Of The Amorphophallus titanum Becc In Sumatera Faristy, Annisya Fhadilah Putri vauzia, Vauzia Amorphophallus Amorphophallus titanum Endemic Sumatera Amorphophallus has 176 species spread throughout the world, 25 of which are found in Indonesia. Of the 25 species found in Indonesia, 8 of them are endemic to Sumatra. One type of Amorphophallus found on the island of Sumatra is Amorphophallus titanum, whose survival in its natural habitat is threatened by deforestation and forest degradation. As an endemic plant, A. titanum is also more vulnerable to anthropogenic threats and environmental change, and therefore faces a greater risk of extinction than more widespread species. To prevent species extinction and as a form of biodiversity conservation, information is needed that presents the population status of A. titanum in its natural habitat. This article aims to provide information about the population of corpse flowers (Amorphophallus titanum Becc) in Sumatra. The research method used is a literature review. Data was obtained from journals and articles published from 2005 to 2023. Based on research conducted, it is known that A. titanum is often found in Bengkulu, Lampung, Jambi, North Sumatra and West Sumatra. The highest population of A. titanum is in Muara Hemat Village, South Kerinci Resort, Kerinci Seblat National Park, Jambi, with a total of 83 individuals. In Bengkulu, A. titanum is found in several locations; in KHDTK (Forest Areas with Special Purposes) as many as 64 individuals. At Ketapang Water, Jufi Hill and Datar Lebar Waterfall there were 56 individuals. In the Mount IV Kepahiang Nature Reserve there are 56 individuals. In Tebat Monok, Air Selimang and Palak Siring the number is 52 individuals. Meanwhile in North Sumatra, specifically in the Sibolangit Nature Reserve, Sibolangit Nature Reserve, Dolok Sipirok Nature Reserve, and Namo Suro Baru Village, 32 individuals were found. In Palupuah, Agam Regency, and South Solok, West Sumatra, there are 24 individuals, and also in the Liwa Botanical Gardens, Lampung, there are 4 individuals.

Potensi Jamur Endofit dari Daun Jambu Nasi-Nasi (Syzygium zeylanicum) sebagai Antibiotik Alami dalam Mengobati Jerawat Syarifah, Syarifah Yusfarani, Delia Kharism, Sully P Fauzan, Ahmad R Farmakonogsi Mikologi dan Mikrobiologi Endophytic fungi are microscopic organisms that live in leaves, stem bark and root bark at certain periods by forming colonies without harming their hosts, and even have a mutually beneficial relationship. Endophytic fungi generally produce secondary metabolites that have useful biological activities such as antibacterial, antioxidant, antiviral and anticancer. Endophytic fungi can be found in various types of plants, especially in medicinal plants, such as Syzygium zeylanicum, which is one of the many medicinal plants found in Indonesia. A total of 6 endophytic fungal isolates were successfully isolated from the nasi-nasi guava, namely Septonema, Lasiodiplodia pseudotheobromae, Trichoderma aureoviridae, Acremonium, Sclerotium, Scopulariopsis asperula. Antibacterial activity was carried out using the agar diffusion method. The percentage of antibacterial activity values shows that SL1, SL2, SL3, SL4, SL5 and SL 6 all have strong antibacterial activity against the bacteria Staphylococcus aureus and Propionibacterium acnes, while for the bacteria Staphylococcus epidermidis it is found that isolates SL1, SL4 and SL6 have strong antibacterial activity and isolates SL2, SL3 and SL5 had moderate antibacterial activity. This category shows that the extract of the endophytic fungus Syzygium zeyanicum has antibacterial potential.

INVENTORY OF CELASTRACEAE (PARUPUK-PARUPUKAN) SPECIES BASED ON HERBARIUM SPECIMENS OF ANDALAS UNIVERSITY (ANDA) Ikhsan, Muhammad Nurainas, Nurainas Syamsuardi, Syamsuardi Celastraceae has various benefits. However, research on the identification and distribution of Celastraceae species, particularly in Sumatra, is still limited. Therefore, further studies are needed on the identification and distribution of Celastraceae in Sumatra. The Herbarium of Universitas Andalas (ANDA) has a collection of Celastraceae specimens, most of which have not been identified to the species level. Given the high diversity of flora in Indonesia, especially in Sumatra, identifying Celastraceae species is an important step to better understand the potential of these plants. This study aims to determine Celastraceae species and their distribution based on specimens from Herbarium ANDA, which is expected to enrich scientific knowledge about biodiversity in Indonesia and open up opportunities for further utilization of the Celastraceae family. The method used is herbarium-based, involving the management of specimens from Herbarium ANDA. This study identified fifteen species from six genera: Celastrus, Euonymus, Glyptopetalum, Lophopetalum, Microtropis, and Salacia. The distribution of Celastraceae plants in Herbarium ANDA covers West Sumatra, North Sumatra, Riau, and one species from Kagoshima Prefecture, Japan. Most specimens are from West Sumatra, with the distribution detailed as follows: seven species from Padang; two species each from Solok, Lima Puluh Kota, Pasaman, and Mentawai; and one species from Agam and Pasaman Barat. In Riau Province, two species were found in Kampar, and in North Sumatra Province, one species was found in South Tapanuli.Keywords:  Celastraceae, Distribution, Inventory, Species.

Identification Of Intestinal Worms On Horses At The Cipanas Presidential Palace Using The Flotation Method Siagian, Tetty Barunawati Malik, Abdul Nuriman, Trian Gustiana Local horse Sandalwood Strongylid Strongylus vulgaris Sumbawa Parasitology The Cipanas Presidential Palace has local horses with sandalwood and sumbawa types that are used as riding horses and decorative horses to beautify the palace. The horses are kept by being stabled in the afternoon until morning, and being let out in the morning until evening. This maintenance method certainly carries a risk of gastrointestinal worm infection and often worm infections in horses do not cause clinical symptoms. The purpose of the study was to identify the types of gastrointestinal worms that infect horses at the Cipanas Presidential Palace. This study used fecal samples from 26 horses that were examined using the flotation method. The results of the examination showed that 24 samples were positive for strongylid worm eggs. The percentage of worm infection in horses at the Cipanas Presidential Palace was 92.3%. The findings of Strongylid worm eggs are oval with thin walls and have morula like grapes. Adult worms that have Strongylid worm eggs are Strongylus vulgaris. The cause of horses being infected with worms is due to being let out too early, giving wet grass that is not wilted, and storing wet grass in a damp warehouse. Based on the research above, it was concluded that local horses at the Cipanas Presidential Palace were infected with Strongylus vulgaris worms.

Ant Species Composition Collected by Pan Traps in a Rehabilitated Coal Mining Area in Sawahlunto City, West Sumatra Tasman, Ratna Juwita Nurdin, Jabang Herwina, Henny Jasmi, Jasmi Janra, Muhammad Nazri Satria, Rijal Ant Composition Pan Traps Rehabilitated coal mining Sawahlunto Hymenoptera Pan traps is a popular technique for determining the diversity of pollinating insects in different settings. These traps are effective for field use and can quickly produce sample data because they are simple to operate and don't require any specific equipment to be deployed. Pan traps, however, also catch a variety of non-pollinator insects in addition to pollinating insects. In this study, the Pan traps methods were used in three different habitat types: rice-field, Acacia agroforestry and secondary forest on reclaimed coal mining site. Fourteen members of the Formicidae family with 11 species, 9 genera, 8 tribes, and 3 subfamilies were found from all of the combined traps. The most common species, with four records, was Camponotus arrogans, which was regularly found in all types of habitat. With 9 species and 14 individuals, blue pan traps caught the greatest diversity of ant species, while yellow pan traps were the least successful with one species and one individual. Comprehending the variables that impact ant diversity and abundance in various habitat types, as well as their interactions with the environment, can yield significant insights on the quality of habitats and function as markers of environmental alterations. This information is essential for the management of habitats and conservation initiatives.

Perubahan Tutupan Hutan: Studi Kasus Sumatra Barat Afdhal, Taufiq Wibisono, Hariyo Tabah Aadrean, Aadrean forest cover change West Sumatra land-use conversion deforestation environmental impact The expansion of agricultural and plantation areas, and demands for improved accessibility, particularly on gentler slopes, has accelerated deforestation in West Sumatera. This study investigates changes in forest cover in West Sumatera over the period from 2000 to 2050, using two initial cover datasets from 2000 and 2015. We used driving variables, including elevation, slope, and roads, processed through the Change Modeller in IDRISI TerrSet. Modelling results indicate that forest cover changes are significantly influenced by topography, with gentler slopes experiencing faster rates of deforestation compared to steeper areas. Regions with flat land and easy access are particularly vulnerable to large-scale conversion for agricultural use, especially for palm oil plantations. The results underscore the interplay between infrastructure development and forest cover changes, highlighting the need for careful consideration of environmental impacts in planning and policy making. This study urges the policymakers to implement strategic spatial planning and land-use monitoring to mitigate impacts of deforestation to ensure forest sustainability in West Sumatera.

Species Distribution Modelling on Long-tailed Macaque (Macaca fascicularis) in Padang, West Sumatra Utami, Radila Novarino, Wilson Rizaldi, Rizaldi Ecology Animal Human activity is a major factor in the decline of primate biodiversity, including long-tailed macaques, which thrive in varied habitats, even near human settlements. This overlap can lead to conflicts for both humans and macaques. The objective of this study is to determine the distribution of long-tailed macaques through direct observation and potential distribution based on habitat suitability modelling using MaxEnt. Six environmental variables were selected based on the ecological traits of long-tailed macaques, including forest cover, population density, distance to roads, distance to forests, distance to conservation areas, and land use type. Moreover, 32 coordinate points were identified in Padang for locating long-tailed macaque and modelled using MaxEnt. The results indicate that long-tailed macaques are primarily distributed in areas with forest cover but are close to anthropogenic activities. The modelling reveals that the habitat suitability for this species in Padang tends to be low to moderate. The environmental variables that exert the most significant influence on their distribution are distance to roads and forest cover (53.3% and 20.1% respectively). Consequently, areas with a higher potential of habitat suitability required particular attention to manage conflicts and populations to avoid potential negative impacts that could arise.

A Rapid Assessment: Insect Diversity Around the Stingless Bee Colony in Edufarm Universitas Andalas Ilmi, Miftahul Henny Herwina Dahelmi Alponsin Jasmi Rusdimansyah diversity index dominance species insects quadra protocol stingless bee Insects dominate the animal kingdom, comprising nearly 80% of all animal species, with around 250,000 species found in Indonesia. Among these, stingless bees are a diverse  group with over 60 genera. Some stingless bees are cultivated in meliponiculture, practiced around homes and plantations. This study aimed to assess insect diversity near stingless bee colonies in the Education Farm (Edufarm), Universitas Andalas, through a rapid assessment conducted over two days in May 2024. A transect was established with three U-shaped sub-transects surrounding a stingless bee colony. The modify quadra protocol sampling (honey bait traps, leaf litter, soil cores, and hand collecting) was used around the colony. The study identified 1153 individuals from 6 orders, 9 families, and 15 species of insects, with Formicidae from Hymenoptera being the most dominant. This research offers valuable insights into insect diversity around stingless bee colonies at Edufarm and can inform better management strategies for stingless bees and the ecological structure of surrounding environments.

Evaluating Species Distribution Models (SDMs) for Efficient and Accurate Detection of Wild Species Across Landscapes Taufiq, Ahmad Nurainas Species Distribution Models Environmental Niche Modeling Species Detection Biodiversity Monitoring Maxent Modeling Field Survey Efficiency Species distribution models (SDMs) have been used across continents and taxonomic groups to guide field surveys and improve detection efficiency. In several studies, SDM-guided approaches achieved Area Under the Curve values between 0.90 and 0.976, with some reports documenting the discovery of new populations (e.g., 4 of 8 species or 5-16 additional sites) and time savings of up to 70% compared with unsystematic surveys. One study noted that Gaussian Process models operated 70 times faster than an alternative estimation method. Additional work indicates that SDMs narrow survey areas and enhance cost effectiveness, particularly when environmental layers and robust occurrence data support model development. These studies show that, when applied with methods such as Maxent and ensemble approaches, SDMs offer a viable alternative to direct field surveys for locating wild species over large areas. Limitations arise when data quality or model specification is insufficient, suggesting that careful design remains essential for reliable outcomes.
