Abstract. Lillo EP, Malaki AB, Alcazar SMT, Rosales R, Redoblado BR, Pantinople E, Nuevo RU, Cutillar RC, Almirante A, Buot IE Jr. 2020. Diversity and distribution of ferns in forest over limestone in Cebu Island Key Biodiversity Areas (KBAs), Philippines. Biodiversitas 21: 413-421. Three forest areas of Cebu Island, Philippines were recognized as Key Biodiversity Areas (KBAs) by Department of Environment and Natural Resources [DENR], Philippines based on the criteria of vulnerability and irreplaceability, namely Nug-as of Alcoy, Palinpinon Range of Dalaguete, and Mt. Lantoy of Argao. The study aimed to assess the composition, diversity, and distribution of ferns in the aforementioned KBA's. Quadrat at 20 m x 20 m was established within the 2000 m transect line at an interval of 200 m. Result showed a total of 50 species, categorized into 15 families and 29 genera for 30 quadrats. Twelve species were considered as new records on Cebu. Thirteen species were recorded in both Mt. Lantoy and Nug-as forest KBA’s, but absent in Palinpinon range. While 6 species were recorded as unique to Nug-as forest. Nug-as forest and Mt. Lantoy showed a relative value of very high species diversity. Nug-as forest and Mt. Lantoy KBA forming into one cluster and Palinpinon range proved to have a distinct fern species composition, and form another cluster. Local government units (LGU) in every KBA need to recognize the necessity of biodiversity information in their localities that would facilitate information sharing and awareness, hence enhancing protection and conservation of unique biodiversity, since they are at the forefront of local action.

Abstract. Elfita, Mardiyanto, Fitrya, Larasati JE, Julinar, Widjajanti H, Muharni. 2019. Antibacterial activity of Cordyline fruticosa leaf extracts and its endophytic fungi extracts. Biodiversitas 20: 3804-3812. Endophytic fungi live by forming colonies in plant tissues without harming the host plant. Cordyline fruticose has been used as traditional medicine for the treatment of pathogenic bacterial infections; therefore, its endophytic fungi are expected to have similar activity. In this study, C. fruticosa leaves were extracted with gradient solvents and evaluated for their antibacterial activity using the Kirby–Bauer method against Gram-negative (Salmonella typhi, Escherichia coli) and Gram-positive (Staphylococcus aureus, Bacillus subtilis) bacteria. The extracts of endophytic fungi from C. fruticosa leaves were evaluated for their antibacterial activity, as well. The endophytic fungus with good antibacterial activity was identified by molecular and phylogenetic methods. Chemical compounds from endophytic fungus DB1 were isolated by chromatography and subsequently determined by spectroscopy. The methanol extract of C. fruticosa leaves showed strong antibacterial activity equivalent to the endophytic fungus (DB1). Molecular identification and analysis through the phylogenetic tree showed that the DB1 fungus has a high level of similarity to Neurospora tetrasperma strain APBSDSF108. The antibacterial compounds (compound 1 and 2) isolated from the endophytic fungus DB1 were identified as 4-hydroxy-5-phenylpenta-1,3-dien-1-yl acetate and ergosterol, respectively.

Abstract. Nelly N, Khairul U, Putri AY, Hamid H, Syahrawati MY. 2020. Isolation and selection of maize plants rhizobacteria with the potential of entomopathogens against Spodoptera litura F (Lepidoptera: Noctuidae). Biodiversitas 21: 753-758.  Spodoptera litura is a polyphagous pest that can be controlled with entomopathogen. Furthermore, Rhizobacteria derived from the rhizosphere of corn plants are expected to control this pest. This research, therefore, was conducted to obtain the entomopathogenic rhizobacteria to control S. litura derived from the rhizosphere of corn plants. Data sampling was carried out at corn plantations in West Pasaman Regency, while Isolation, selection, and testing of S. litura were conducted at the Biological Control Laboratory of the Plant Protection Department, Faculty of Agriculture, Andalas University. The method uses serial glowing techniques cultured on Nutrient Agar (NA) media, with the selected isolates tested for their ability as an entomopathogen against S. litura. The feed dip method given to S. litura larvae was used to test for rhizobacteria virulence determination with entomopathogen, used to observe the larvae mortality rate, percentage of pupae, and adult formed. Furthermore, observation of morphological and physiological characters was conducted on entomopathogenic rhizobacteria, with hypersensitive testing conducted on Mirabilis jalapa plants. The results of rhizobacterial isolation from corn rhizosphere obtained 12 entomopathogenic isolates. Deadly larvae of S. litura 51-91.11%, 0.00-8.89% pupae, and 0.00- 6.67% adult were formed. The gram test results obtained approximately 8;4 positive (+) and four negative isolates (-), respectively. Hypersensitivity test results found that one of 12 isolates caused necrotic reactions in Mirabilis jalapa. Therefore, a total of 11 rhizobacteria isolates are entomopathogenic and safe to be used as S. litura biological control agents.

Abstract. Wakhid, Rauf A, Krisanti M, Sumertajaya IM, Maryana N. 2020. Species richness and diversity of aquatic insects inhabiting rice fields in Bogor, West Java, Indonesia. Biodiversitas 21: 34-42. Rice fields occupy the largest cultivated area in agricultural landscape in Indonesia and support a variety of living organisms, including aquatic insects. This study was conducted with the objective to determine the species richness and diversity of aquatic insects inhabiting rice fields. Sampling was made in March, May, and July 2017 in rice fields at Situgede, Pandansari, and Kawungluwuk (Bogor region, West Java, Indonesia), and carried out by dragging dip net on the bottom along the edge of the rice plots. A total of 3,306 individuals representing 45 species of aquatic insects belonging to 30 genera, 20 families, and seven orders were recorded. Order Hemiptera was the most abundance comprising 28.89% of the total insects collected, followed by Diptera (24.80%), Coleoptera (24.41%), and Odonata (21.42%). Functional feeding group analysis showed that collectors-gatherers had the highest proportion (40 - 46%), followed by predators (23-44%) and scrapers (10-35%). Rank-abundance curve showed low species evenness with the four most abundant species were Micronecta siva (Kirkaldy) (Hemiptera: Micronectidae), Chironomus sp. (Diptera: Chironomidae), Orthetrum sabina (Drury) (Odonata: Libellulidae), and Helochares sp. (Coleoptera: Hydrophilidae). The Shannon-Wiener index showed the lowest value (H’=1.84) at Situgede and the highest (H’=2.05) at Pandansari. Richness estimate and individual-based rarefaction curve revealed that rice fields at Pandansari have more species richness than the other two sites. This study provides some insights into the aquatic insect community of the human-made ecosystem and suggests that the ecological approach to pest management is necessary for maintaining ecosystem health and promoting biodiversity.

Abstract. Abdulah L, Suhendang E, Purnomo H, Mattangaran JR. 2020. Measuring the sustainability of wood consumption at the household level in Indonesia: Case study in Bogor, Indonesia. Biodiversitas 21: 457-464. Data on consumption of wood products at the end-user level does not yet exist. This is caused by variations in the shape of wood products and raw materials used. Meanwhile, information on the level of consumption per capita is needed to measure sustainability consumption at the household level, determine the volume of wood production and carbon storage in wood products in the household. The novelty of this study is in method for measure wood product consumption. The aim of this study was to estimate the level of wood consumption at the household level in the form of use for construction and furniture. The method used was a survey of wood products at the industrial level and to make a database and then confirmed to households to determine the level of consumption. The results showed that wood products in the household are divided into 2 main parts namely construction and furniture. The level of wood consumption varied greatly depending on the type of roof, the number of doors and windows and the amount of furniture used. The level of consumption in Bogor reached 0.1 m3 per capita. This consumption was influenced by the time of use and the size of family.

Abstract. Mekhadmi NE, Ramdani M, Lograda T, Chalard P, Figueredo G. 2019. Chemotypes and antibacterial activity of Matricaria pubescens of Algeria. Biodiversitas 20: 3170-3179. The objectives of this study were to determine the chemical composition and to evaluate the antibacterial activity of Matricaria pubescens L. essential oils from 14 sampling locations in southern Algeria. The extraction of essential oils was carried out by the hydro-distillation; the analysis of chemical composition of essential oil was carried out by GC-MS. Antibacterial activity was performed by disc diffusion method at the undiluted and diluted essential oil (1/1, 1:2, 1:4 and 1:8 v:v of DMSO) against eight species of bacteria (Bacillus cereus, Escherichia coli, Klebsiella pneumoniae, Listeria innocua, Proteus mirabilis, Pseudomonas aeruginosa, Salmonella enterica and Staphylococcus aureus). The results showed that the average yields of essential oils were 0.4 ± 0.27%. A total of 34 components were identified, averaging 99.22 ± 0.8% of the total oils. The main components were ?-ocimene (Z) (47.41 ± 13.67%), ?-pinene (19 ± 7.36%), ?-bulnesene (4.96 ± 10.6%), ocimene-allo (4.46 ± 1.3%), 1-phenyl-penta-2,4-diyne (4.06 ± 5.7%), limonene (3.84 ± 1.8%), caryophyllene oxide (2.36 ± 3.6%) and ?-bisabolene-E (2.08 ± 4.3%). Based on the UPGMA cluster analysis, there were two distinct clades of M. pubescens. This species has a chemical polymorphism with different chemotypes marked in nature. There were four chemotypes identified in the essential oil of M. pubescens in the region studied. The essential oil of M. pubescens has antibacterial activity against eight bacteria tested in a concentration-dependent manner.

Abstract. Fachrial E, Anggraini S, Harmileni, Nugroho TT, Saryono. 2019. Isolation and molecular identification of carbohydrase and protease producing Bacillus subtilis JCM 1465 isolated from Penen Hot Springs in North Sumatra, Indonesia. Biodiversitas 20: 3493-3498. The application of enzymes industrially is increasing every year and thermophilic microbes are a promising source of these enzymes for industrial use due to their temperature stability. The aim of this study, therefore, was to isolate, characterize and identify the enzyme producer-thermophilic bacteria from the Penen Hot Spring in Deli Serdang, North Sumatra, Indonesia. In the experimental setup, carbohydrase activities including inulinase and amylase were determined by the formation of clear zone around the colonies after soaking with Lugol on the TSA medium supplemented with 1% inulin powder and 1% starch. Similarly, the protease activities were determined by the formation of clear zone around the colonies on Skim Milk Agar Medium. Then, of the 11 isolates, only one known as UTMP 12 showed maximum enzyme activity. The isolate was then characterized based on morphology and biochemistry and found to be Bacillus subtilis strain JCM 1465 (accession number NR_113265, homolog 99.72%). Furthermore, this is the first study on carbohydrase and protease activities of Bacillus subtilis strain JCM 1465 and the result shows that the thermophilic bacteria are needed in the production of carbohydrase and protease.

Abstract. Herlinda S, Karenina T, Irsan C, Pujiastuti Y. 2019. Arthropods inhabiting flowering non-crop plants and adaptive vegetables planted around paddy fields of freshwater swamps of South Sumatra, Indonesia. Biodiversitas 20: 3328-3339. Local farmers in freshwater swamps of South Sumatra traditionally plant adaptive flowering vegetables surrounding paddy fields and let wild flowering plants or non-crop plants grow on the embankment. This research aimed to determine the species of non-crop plants and adaptive vegetables surrounding the freshwater swamp paddy fields as habitats and niches of arthropods. This study used four species of flowering non-crop plants (Zinnia sp., Tagetes erecta, Cosmos caudatus, Sesamum indicum) and four species of vegetables (Vigna unguiculata, Momordica charantia, Cucumis sativus, Luffa acutangula) planted around the paddy fields. While the arthropods were collected using sweep nets. There were 24 species of predatory arthropods, three species of parasitoids, 17 species of herbivores, and nine species of neutral insects found in the non-crop plants and vegetables. The non-crop plant and vegetable species that were the most chosen by the predatory arthropods were Zinnia sp. and M. charantia, respectively. Species of the non-crop plants and vegetables chosen by the parasitoids were T. erecta and M. charantia, respectively. Those non-crop plants and adaptive vegetables were also the most chosen plants by the predatory arthropods for their habitats and niches. Therefore, for the conservation of natural enemies, it is better to use Zinnia sp., T. erecta, and M. charantia.

Abstract. Karyati, Widiati KY, Karmini, Mulyadi R. 2019. Development of allometric relationships for estimate above ground biomass of trees in the tropical abandoned lands. Biodiversitas 20: 3508-3516. The abandoned lands have important role in the ecological function as well as carbon sequestration. The allometric equations to estimate above ground biomass in abandoned land are still limited available. This study objective was to develop allometric relationships between tree size variables (diameter at breast height (DBH) and tree height) and leaf, branch, trunk, and total above ground biomass (TAGB) in abandoned land in East Kalimantan, Indonesia. The correlation coefficients between stem DBH and tree height to leaf and branch indicating a relatively weak relationship. The moderately strong relationships were showed by DBH and tree height to trunk and TAGB. The specific allometric equation of above ground biomass for different land use and land type is needed to estimate the accurate TAGB in the site.

Abstract. Umar W, Tassakka ACMAR, Jompa J. 2019. High genetic connectivity in a scleractinian coral (Lobophyllia corymbosa) around Sulawesi, Indonesia. Biodiversitas 20: 3484-3492. The life cycle of scleractinian corals begins with a pelagic larval phase subject to the influence of currents, with the potential to disperse propagules over vast geographical distances. We investigated the mitochondrial COI genome to investigate genetic population structure and potential biophysical barriers (in particular water mass movements) that could affect connectivity between populations in the seas around Sulawesi, in the Indonesian Coral Triangle. Lobophyllia corymbosa was selected as representative of corals with a broadcast spawning reproductive strategy and relatively long Pelagic Larval Dispersal (PLD) period. Analysis of mtDNA sequences from 103 colonies collected at depths of 3 to 10 meters in 4 locations (Manado, Toli-Toli, Spermonde, and Wakatobi) resulted in FST = 0.00632, indicating no genetic isolation or significant differentiation. The tendency towards genetic homogeneity across the entire population indicates that gene flow has been maintained, most likely through widespread dispersal of propagules within the study area. The dominant surface flow directions recorded during the reproductive period of this species provide support for this gene flow model, as the currents could enable dispersal and recruitment patterns maintaining connectivity between L. corymbosa populations around Sulawesi.
