Abstract. Mardiani MO, Kusumawati IA, Purnamasari E, Prayogo C, van Noordwijk V, Hairiah K. 2022. Local ecological knowledge of coffee agroforestry farmers on earthworms and their relation to soil quality in East Java (Indonesia). Biodiversitas 23: 3344-3354. Farmers manage their land-based on their understanding of biotic and abiotic factors, including soils, and how these factors affect crop growth and productivity. Their local ecological knowledge (LEK) is built upon intergenerational transfer and can use concepts that don’t directly match those of current science-based ecological knowledge. We explored farmer LEK related to soil organic matter management and earthworms in coffee-based agroforestry systems on volcanic slopes in East Java (Indonesia) by in-depth interviews with key informants and by surveying the concurrence of respondents, stratified by gender and age, with resulting statements. The term used in the local language for earthworms (‘cacing tanah’) included a range of species. According to 22% (n=48) of farmers, small earthworms (probably Pontoscolex corethrurus) are harmful to coffee trees because they eat the roots. Also, 54% (n=48) of farmers thought earthworms that eat soil cause a decrease in soil volume. However, according to the farmers, large earthworms (reddish-brown) can fertilize the soil by leaving their casts on the soil surface. Such worms are often found in coffee agroforestry systems. Farmers have little explicit knowledge of the activities of earthworms and their relation with litter as a source of food. Farmer knowledge of ecosystem services provided by earthworms can enrich current scientific literature and trigger a two-way dialogue.

Yield evaluation of curly chili lines in three lowland locations.Biodiversitas 23: 3219-3223. Yield evaluation of curly chili lines in three lowland locations. Increased consumption of spicy food is the latest trend in the 21st century. Curly chili as a type of chili that has a spiciness that is acceptable to the community is needed to meet consumer needs. This study aims to identify the growth, fruit, and yield components of several genotypes of curly chili. The study was conducted in multi-location at four planting sites. Each location used a randomized complete block design (RCBD) with three replications. Each replication used ten sample plants. Neno IPB as a chili variety produced by breeding has a faster flowering and harvesting time than all other genotypes. In addition, the productivity of Neno IPB was high and consistent in all cultivation locations. The results of the pheatmap analysis show that Neno IPB was one group with commercial varieties (Laris and Kastilo F1). A significant positive correlation based on Pearson's analysis was shown in the combination of flowering time-harvesting time, fruit length-fruit weight, and fruit weight per plant-total fruit per plant-productivity. However, flowering time-harvesting time-fruit weight per plant showed a significant negative correlation.

Abstract. Harmonis, Rahim A, Hidayat HA, Saud OR, Wilujeng M, Sampe R, Kartika KF, Aminudin, Butar TB. 2022. Diversity of butterflies in the tropical wetland of Kayan-Sembakung Delta, North Kalimantan, Indonesia. Biodiversitas 23: 3303-3312. Butterflies, which belong to the order Lepidoptera, are considered superior biological indicators to evaluate environmental conditions in various types of habitats due to their high richness in biodiversity, short generation time, good movement, and high sensitivity. Since butterflies produce various benefits for the ecosystem, their conservation currently receives significant attention in order to improve human well-being. However, there is still limited research about butterfly diversity in tropical wetlands, especially in Borneo (Kalimantan) Island. Herein, we identify the diversity of butterflies found in the Kayan-Sembakung Delta, North Kalimantan, which is still unexplored so far. The area was dominated by mangroves, peat swamps, and brackish swamps. The research locations inside the Kayan-Sembakung Delta were divided into 20 groups. The specimen was collected by an aerial insect net and bait traps. The diversity index, taxonomy structure, and domination index were further investigated. The results showed that the highest individuals (69) and species (36) had been found in Pembeliangan. Altogether, we found 608 individuals of 92 species in the areas studied. Among others, the family of Nymphalidae was noted as the most dominant. We stated that the diversity of butterflies was also influenced by the type of habitat, as it could be found at the peat swamp forest where the highest species were found. In the meantime, some unique species have been found in the Kayan-Sembakung Delta, including Arhopala overdijkinki, Hypolycaena thecloides, Drupadia johorensis, Idea leuconoe, and Polyura jalysus. The results of this study are expected to give more information for future management and conservation of the wetland areas, especially in the Kayan-Sembakung Delta.

Abstract. Rahmawati RB, Widiyatno, Hardiwinoto S, Budiadi, Nugroho WD, Wibowo A, Rodiana D. 2022. Effect of spacing on growth, carbon sequestration, and wood quality of 8-year-old clonal teak plantation for sustainable forest teak management in Java Monsoon Forest. Biodiversitas 23: 4180-4188. Lowland monsoon forest dominated by teak was one of the tropical forest types that can contribute to producing wood production, carbon storage, reduction of emissions, and other ecosystem services. Increasing teak forest productivity could be obtained through teak breeding to get superior teak clones with high diameter growth. Thus, spacing is an important consideration for optimizing the growth, carbon sequestration, and wood properties of teak. However, the study of the growth, carbon sequestration, and wood quality of teak was conducted separately. This research used a selected teak clone aged 8 years with RCBD design with 4 blocks as replications. There were four different spacing as treatments, namely 10 m x 2 m, 8 m x 2 m, 6 m x 2 m, and 3 m x 3 m. The results showed that spacing was a significant effect on DBH, tree height, bole height, carbon sequestration, and volume of teak clones aged 8 years. On the other hand, spacing didn’t significantly affect the physical and mechanical properties of wood. The wood quality test showed that the 6 m x 2 m spacing had high values of bending strength and compressive strength parallel. The highest percentage of heartwood was at a narrow spacing of 6 m x 2 m and did not differ significantly with wide spacing. This indicated that wide spacing was beneficial in terms of teak growth, but wide spacing didn’t significantly affect on wood quality of the teak.

Abstract. Yuliansyah. Haqiqi MT, Setiawan KA, Setiawan A, Saputra PD, Romadlon HSI, Mukhdlor A, Ramadhan R, Amirta R. 2022. Fast-growing native tree species to the secondary forest of East Kalimantan, Indonesia: Physicochemical properties of woody materials for bioelectricity feedstocks. Biodiversitas 23: 3379-3386. The conversion of woody biomass into electricity through a thermochemical process has recently attracted significant attention worldwide to promote green energy production. It provides a low-cost and straightforward operation promising for developing rural areas, especially with limited transportation access. In East Kalimantan Province, almost all remote areas are surrounded by forests with high tree species diversity, which is the potential to be utilized for sustainable feedstocks in electric power plants. This study pointed out the energy potential produced from woody biomass of selected fast-growing tree species native to East Kalimantan secondary tropical forest: Elaeocarpus ferrugineus (Jacq.) Steud., Ficus aurata (Miq.) Miq., Fordia splendidissima (Blume ex Miq.) Buijsen, Lindera lucida (Blume) Boerl., Mallotus paniculatus (Lam.) Mull. Arg. and Schima wallichii (DC). Their wood physicochemical properties were firstly investigated. Furthermore, each species' wood quality for solid energy purposes was presented as the fuel value index (FVI). The results revealed that the change from greenwood into wood chip effectively removed the moisture content, thus improving efficiency to achieve higher energy potency. Our findings showed that the highest energy potency was obtained from the wood chip of F. splendidissima (3.61 MWh/ton), followed by S. wallichii (2.98 MWh/ton). A similar pattern was also found in FVI determination showing that the wood chip of S. Splendidissima had the greatest value (8970). Therefore, we observed that the high quality of S. splendidissima compared to other selected fast-growing species indicates its high suitability for further large-scale crop plantation to supply wood chips for biomass-based electricity generation.

Abstract. Aritonang SN, Roza E, Yetmaneli, Sandra A, Rizqan. 2022. Characterization of Lactic Acid Bacteria from Buffalo Dairy Product (Dadiah) as Potential Probiotics. Biodiversitas 23: 4418-4423. Dadiah is one of fermented milk from West Sumatra which made from buffalo milk. These product made traditionally by pouring fresh buffalo milk into a bamboo stick covered with banana leaves and fermenting at room temperature for two days. The study's objective was to isolate and identify Lactic Acid Bacteria (LAB) from dadiah as candidates for probiotics. The factors that are considered are LAB Characterization, Biochemical and Microscopic Characterization of LAB Isolate, Bacterial Resistance in Acidic conditions, Bile Salts Resistance, and Antimicrobial Activity. Furthermore the isolate identify by Polymerase Chain Reaction (PCR) using 16S rRNA. Samples of dadiah were collected from five farmers in Tanjung Bonai Village, North Lintau Buo Regency, Tanah Datar District, West Sumatra, Indonesia. Observations were made in four replications, and the data obtained were analyzed descriptively. The total colony of lactic acid bacteria from dadiah was 7x108-23x108 CFU/mL. LAB isolates from dadiah were classified as Gram-positive bacilli. The isolates are resistant to acidic conditions and bile salts and have inhibitory activity against pathogenic bacteria. Identifying the selected isolate using the 16S rRNA showed that the isolate had similarities with Lactobacillus casei strain HDS-01. It can be concluded that dadiah used in this study is as a probiotic food.

Abstract. Oktavia D, Pratiwi SD, Munawaroh S, Hikmat A, Hilwan I. 2022. The potential of medicinal plants from heath forest: Local knowledge from Kelubi Village, Belitung Island, Indonesia. Biodiversitas 23: 3553-3560. The heath forest ecosystem is home to hundreds of species in Belitung Island and is home to medicinal plant resources. The Belitung people prefer to use medicinal plants due to their easy availability and cheap therapy, compared to costly modern pharmaceuticals. In this study, we investigated the potential of medicinal plants from heath forests according to the local knowledge of the Belitung Malay community. This study was conducted in Kelubi Village, Belitung Island, Indonesia. Data and information related to medicinal plant properties were obtained through interviews with local people using an in-depth interview technique. We documented 86 species belonging to 48 families. The medicinal plants are classified into 48 families. The most abundant families are Rubiaceae (8 species), and Myrtaceae (8 species). Many species from the Myrtaceae family are used as medicinal species, such as, jemang (Rhodamnia cinerea), gelam (Melaleuca leucadendra), keremuntingan (Rhodomyrtus tomentosa), and sekudong pelandok (Syzygium buxifolium). The percentages of medicinal plant diversity based on habitus were 45% trees, 21% woody lianas, 13% small trees, 13% herbs, and 8% lianas. We also found that 23 species of medicinal plants were used as herbs after childbirth, and 10 species of plants were used to treat fever. Belitung Malay people use plants for traditional medicine to solve some diseases and therapy. We suggest that conservation efforts for the heath forest ecosystem should be a priority for the sustainable use of medicinal plants on Belitung Island.

Abstract. Rezekiah AA, Ruslan M, Kadir S, Mahmud. 2022. Vegetation composition and structure across land use types in a rotational cultivation system in Meratus Mountain, South Kalimantan, Indonesia. Biodiversitas 23: 4234-4242. The rotational cultivation system has become a local ecological knowledge of the Meratus Dayak community in South Kalimantan, Indonesia. This land management applies a cultivation system by dividing land into four types, namely pahumaan (cultivated area of annual crops), balukar anum (former cultivated field aged 3-6 years), jurungan (former field aged 7-12 years), and kabun buah (former fields aged more than 15 years). This study is aimed to investigate the floristic structure and composition of the vegetation in each land use type in the rotational cultivation system conducted by the Dayak Meratus community in three villages (i.e., Loksado, Lok Lahung and Haratai). Vegetation sampling was conducted purposively across four vegetation levels (i.e., seedlings, saplings, poles and trees) and the data was analyzed to calculate Important Value Index (IVI), Shannon-Wiener diversity index, species richness index and evenness index. The results showed that each land type had a certain vegetation structure and composition. In pahumaan, the dominant plant species were annual plants, especially crops. The balukar anum and jurungan were dominated by woody plants, while the kabun buah was dominated by fruit plants. The changes in vegetation structure and composition suggested that the succession process was in progress. The diversity index for each type of land use in the three villages was in the medium to high category. The species richness index was in the low to the high category, while the evenness index for all land uses in the three villages was at a high level. These findings suggest that traditional rotational farming activities carried out by the community did not damage the forest.

Abstract. Rattanawanawong N, Bhumpakphan N, Kutintara U, Sukmasuang R. 2022. Wildlife-vehicle collisions in Khao Yai National Park, Thailand: Impact on native species for some conservation management. Biodiversitas 23: 3050-3061. Wildlife-vehicle collisions (WVCs) remain a major challenge in wildlife management worldwide, especially in conservation areas with transport routes passing through. This study was operated along a 48 km long highway, which conducted 207 surveys in a natural world heritage site from February 2018 to January 2019. A total of 391 wild animal carcasses were found in 90 species. The carcasses found, according to the taxonomic group, were reptiles (67.52%), followed by mammals (14.83%), amphibians (4.35%), birds (3.32%). Reptiles were most affected by road use, especially tortoises in Family Geoemydidae and Family Testudinidae that two critically endangered species were found. This study found that members of Family Colubridae were most affected that 26 species, a total of 144 animal carcasses were found, accounting for 29.15% of the number of all carcasses. The most affected species were forest garden lizard (Calotes emma) in the Family Agamidae, where 99 carcasses were found, accounting for 25.31% of the total. In March showed the highest number of the carcasses, followed by April. All of the carcasses found in the evening slightly more than the morning indicated that wild animals died more during the day than at night. The number of vehicles day-1 significantly affected wildlife mortality per day. Reducing the number of vehicles per day-1 entering and reducing vehicle speed, including the number of tourists, as well as banning travel at night, would mitigate the problem. Further, educational signage about wildlife diversity and the risk of road mortality should be installed at the park to remind visitors about the unique fauna in the national park and emphasize the importance of conservation.

Abstract. Alyousif NA, Al-Tamimi WH, Al-sahib MAA. 2022. Evaluation of the effect of various nutritional and environmental factors on biosurfactant production by Staphylococcus epidermidis. Biodiversitas 23: 3533-3538. Biosurfactants are biological surface-active compounds synthesized mainly by hydrocarbon-utilizing bacteria. The properties of biosurfactants make them promising compounds for the application in various fields. The current study evaluated the effect of various nutritional and environmental factors on biosurfactants produced by Staphylococcus epidermidis. This bacterium, for first time in world was isolated from oilfield reservoir in the current study and identified by 16S rDNA sequencing and considered biosurfactant producer according to screening tests. Several factors were evaluated in the current study to assess the optimal conditions for producing the biosurfactant. The results demonstrated that the best carbon source was olive oil with 2% concentration and glutamic acid was the best nitrogen source with 0.2% concentration. The study demonstrated that the best biosurfactant production was recorded at incubation time of 5 days with a 3% inoculum size. Further study is required to determine the chemical structure of produced biosurfactants and to evaluate the potential application of biosurfactants in various fields, therefore constituting a stimulus for future studies.
