Abstract. Navitasari L, Joko T, Murti RH, Arwiyanto T. 2020. Rhizobacterial community structure in grafted tomato plants infected by Ralstonia solanacearum. Biodiversitas 21: 4888-4895. Bacterial wilt disease caused by Ralstonia solanacearum is a devastating soil-borne vascular disease of tomato leading to a 100% yield loss. One of the alternatives to suppress the infestation of R. solanacearum infestation is the application of grafting techniques, which has been studied and successfully practiced by tomato growers. However, the infestation mode of R. solanacearum and the rhizobacterial community structure in grafted tomato plants are poorly reported. In this study, the rhizobacterial community structure in grafted tomato plants infected by R. solanacearum was investigated. The experiment was conducted on tomato germplasms with the implementation of tube grafting using resistant rootstocks (Amelia from Indonesia, H.7996 from Asian Vegetable Research Development Center/AVRDC) and susceptible scion (Servo from Indonesia). The rhizobacterial community structure was analyzed by metagenomic study under 16S rRNA genes sequencing with a distinct region (16SV3-V4) that was amplified using a specific primer (16SV4: 515F-806R) 5’-GTGCCAGCMGCCGCGGTAA and 5’GGACTACHVHHHTWTCTAAT. The results indicated that the grafted tomato plants and resistant rootstocks that were infected by R. solanacearum showed significantly lower intensity of bacterial wilt disease compared to the susceptible scion. The rhizobacterial community structure in the grafted tomato plants infected by R. solanacearum was indicated by predominant phyla of Proteobacteria, Firmicutes, and Actinobacteria with dominant genera of Pseudomonas and Bacillus. Besides, significant difference was also indicated by species of Geitlerinema sp. in the grafted tomatoes infected by R. solanacearum.

Abstract. Tony F, Soemarno, Wiadnya DGR, Hakim L. 2020. Diversity of reef fish in Halang Melingkau Island, South Kalimantan, Indonesia. Biodiversitas 21: 4804-4812. Reef fish is one benchmark to determine a coral reef ecosystem's biodiversity. Reef fish communities are important in coral reef ecosystems because of their trophic relationships with other biotic components. The aim of this study was to determine the biodiversity of reef fish on Halang Melingkau Island, Kotabaru District, South Kalimantan, Indonesia. This research was conducted in March-August 2019. Coral reef fish data were collected using an underwater visual census method. Transects were applied as close as possible to the substrate using a 50 m roll-up measuring tape. Three transects were applied at each station. A total of 98 reef fish species from 19 families were recorded in this study. The fish community in Halang Melingkau island belongs to the family of Pomacentridae, Labridae, Chaetodontidae, Scaridae, Haemulidae, Lutjanidae, Scolopsidae, Serranidae, Caesionidae, Holocentridae, Siganidae, Pomacanthidae, Apogonidae, Pempheridae, Scorpaenidae, Tetraodontidae, Blenniidae, Platacidae, and Zanclidae. The highest abundance of reef fish was 1.88 ind/m2, and the lowest was 0.14 ind/m2. The dominance index (C) ranged from 0.03 to 0.13, the homogeneity index (E') ranged from 0.72 and 0.94, and the diversity index (H') ranged from 2.17 to 3.53. Water quality data measurements of temperature, brightness, current speed, pH, and DO (Dissolved Oxygen) were within the tolerance limits of water quality standards based on the Minister of Environment Decree No. 51 of 2004, Republic of Indonesia.

Abstract. Hartati S, Muliawati ES. 2020. Short Communication: Genetic variation of Coelogyne pandurata, C. rumphii and their hybrids based on RAPD markers. Biodiversitas 21: 4709-4713. One effort to increase the genetic diversity of orchids is by crossing. This research aims to assess the genetic variation of a hybrid orchid obtained by crossing Coelogyne pandurata and C. rumphii and their hybrids based on RAPD markers. In this research, both parents were analyzed in three replications, while the hybrid was done in 10 replications. The study was conducted by analyzing DNA bands using RAPD markers with six primers, i.e. OPA 02, OPA 07, OPA 13, OPB 12, OPB 17, and OPD 08. Identification of the parents and their F1 hybrids showed 95.83% polymorphic bands with 43 bands measuring 200-2100 bp. The parents of C. rumphii, C. pandurata, and their hybrids showed similarity range of 0.16-1.00. The crossing of C. rumphii and C. pandurata resulted in a similarity of 0.5, shown in two large clusters. The first cluster consisted only of C. pandurata males and the second cluster consisted of C. rumphii females, together with all hybrid individuals. This study succeeded in creating new hybrids of orchids that have different characters from their parents, having a genetic variation of 23%.

Abstract. Yanti AH, Setyawati TR, Kurniatuhadi R. 2020. Isolation and characterization of lactic acid bacteria from fecal pellets, coelomic fluid, and gastrointestinal tract of Nypa worm (Namalycastis rhodochorde) from West Kalimantan, Indonesia. Biodiversitas 21: 4726-4731. Lactic acid bacteria isolated from the intestinal tract as probiotic could be beneficial because they could trigger the growth of the host by enhancing digestibility, increasing their immune system, and inhibiting pathogenic bacteria through the enzymatic process or metabolites production. The purposes of this study were to identify and characterize lactic acid bacteria from fecal pellets, coelomic fluid, and gastrointestinal tract of Nypa worm (Namalycastis rhodochorde). Bacterial isolation was carried out by the pour plate method on de Mann Rogosa Sharp Agar (MRSA). Lactic Acid Bacteria (LAB) isolates were purified and then physiologically characterized by some biochemical tests. Cellulolytic activities were carried out by detecting a clear zone formation on CMC-congo Red Agar. There were 20 isolates of lactic acid bacteria from fecal pellets, coelom fluid, and gastrointestinal tract of nypa worm. Ten isolates (50%) had cellulolytic activity on CMC-phenol red agar. Eight isolates were closely related to the genus Lactobacillus, while two isolates were closely related to the genus Bacillus. These cellulolytic bacteria could be developed further as probiotic in Nypa worm feed.

Abstract. Asra R, Silalahi M, Fijridiyanto IA. 2020. The practice and plants used in Besale ritual healing by the Anak Dalam Tribe in Nyogan Village, Jambi, Indonesia. Biodiversitas 21: 4529-4536. The Anak Dalam Tribe (ADT) is an indigenous ethnic which inhabits the center of Sumatra, especially in Jambi and South Sumatra Provinces, Indonesia. The ADT communities still maintain their traditional rituals; one of them is the Besale ritual healing (BRH). This study aims to analyze the diversity of plants used in BRH by the ADT in Nyogan Village, Jambi Province, Indonesia. The study was conducted with an ethnobotany approach through surveys using interviews and participatory observations. The total number of informants was six persons, namely the leaders and performers of the BRH. The data were analyzed qualitatively using descriptive statistics. The BRH is carried out by a dukunorsidi (shaman), bujang pembayun (dancers), biduan (singers), and inang (assistant). They combine ritual and treatment simultaneously to cure people who have severe illnesses. There are 21 species belong to 20 genera and 12 families of plants used in the BRH. The plants are used to build a hall (place for the BRH), "bird" ornament, and offerings. The most widely used part of the plant is the flowers (34,61%). The plants used in the BRH are fresh materials, which are burned, smoked, hung, and eaten during the ritual.

Abstract. Djunaidi A, Jompa J, Nadiarti N, Bahar A, Tilahunga SD, Lilienfeld D, Hani MS. 2020. Analysis of two whale shark watching destinations in Indonesia: status and ecotourism potential. Biodiversitas 21: 4511-4523. Botubarani in Gorontalo, on the northern coast of Tomini Bay and Labuhan Jambu in Teluk Saleh, Sumbawa recently became whale shark tourism destinations in Indonesia. Both sites offer visitors opportunities to interact with whale sharks, either watching from canoes or snorkelling and diving. In this study, we investigated the status and ecotourism potential of whale shark watching as a form of marine wildlife tourism development in eastern Indonesia by examining the existing operations in both sites. Data were collected using questionnaires administered to local community members and visitors to understand their perceptions, and how this opportunity was valued. Secondary data were collected to explore and understand influencing factors. Findings revealed that whale sharks commonly emerge near bagan lift-nets and other interactive areas as a response to the presence of their favorite prey, anchovies, and rebon shrimp. In general, whale sharks most commonly visit bagan lift nets and can be found in the interaction areas in the morning and stay for couple of hours before swimming away to deeper waters. Out of 119 community respondents in Labuhan Jambu village (Teluk Saleh) and Botubarani, Gorontalo, 80.7% knew about the occurrence of whale sharks in their locality. Of the 111 visitor respondents, 67.6% knew about the whale shark watching sites from word of mouth. The study results also suggest a correlation between chlorophyll-a concentration, anchovies, rebon shrimp and whale sharks. Regarding management approaches to this type of tourism, a local community-based management model is strongly recommended, with 87.4% of respondents showing interest in this approach. The roles and responsibility of local government in developing such tourism is very significant, especially with respect to facilitating appropriate competency within the local community throughout training and education, as suggested by nearly 26% of respondents.

Abstract. Syafrizal, Ramadhan R, Kusuma IW, Egra S, Shimizu K, Kanzaki M, Arung ET. 2020. Diversity and honey properties of stingless bees from meliponiculture in East and North Kalimantan, Indonesia. Biodiversitas 21: 4623-4630. Kalimantan Island in Indonesia is covered by tropical rain forests that are rich in biodiversity. Species, include a stingless bee (Trigona spp.). Recently, stingless bee beekeeping (Meliponiculture) in this region has become popular because the honey has a unique taste, a mix of sweet, sour, and bitter which is highly valued. The objective of this study was to determine the diversity of stingless bee species, the number of colonies, type of hive, and honey properties such as taste, acidity, color, phytochemicals, and radical scavenging activity or antioxidant in meliponiculture in selected areas of Eastern and Northern Kalimantan, Indonesia. The area studied included Samarinda, Balikpapan, Penajam, Bontang, Sangatta, and Tarakan. The study conducted by visiting the farmers, collecting the stingless bees species and bee products (honey, propolis, and bee pollen), pH, color and taste determination, phytochemical screening, and DPPH assay. We found 12 species, with Heterotrigona itama and Tetragonula laeviceps being the main ones cultivated by people in all research areas, except Balikpapan. We counted 111 colonies of T. laeviceps and 99 of H. itama in the meliponiculture. There were three types of hive used by farmers in meliponiculture. Most of the honey tasted sweet and sour with acidity or pH ranging from 3-4, and color from dark brown to light yellow. The phytochemicals contained tannin, alkaloid, flavonoid, triterpenoid, carotenoid, coumarin, saponin, and carbohydrate. The Tetragonula sarawakensis honey was the most potent in term radical scavengers. Our findings showed that stingless bee honey contains antioxidants with phytochemicals that are very useful for human health.

Abstract. Diatin I, Effendi I, Taufik MA. 2020. The production function and profitability analysis of Gracilaria sp. seaweed polyculture with milkfish (Chanos chanos) and black tiger shrimp (Penaeus monodon). Biodiversitas 21: 4747-4754. Gracilaria seaweed is the main ingredient for making agar as a source of food and industry. Gracilaria culture in ponds with a polyculture system is one of the potential seaweed cultivation in Indonesia. This study was aimed to analyze the productivity, production input optimation, and profitability on the polyculture system of Gracilaria sp. with milkfish (Chanos chanos) and black tiger shrimp (Penaeus monodon). The survey method was used to notify the seaweed farmers from Indramayu, West Java, Indonesia. The study data were obtained from all seaweed polyculture farmers populations in the observational location by census containing two farmers groups, namely Gracilaria sp. with milkfish and black tiger shrimp (GMS symbol) and Gracilaria sp. with milkfish (GM symbol) polyculture system. This study resulted that GMS polyculture system obtained higher productivity than GM polyculture system. The GMS business scale was in the increasing return to scale condition, while GM was in the decreasing return to scale condition. The optimal condition of GMS polyculture system was performed by improving the black tiger shrimp seed input, milkfish seed, and milkfish feed, besides declining the working hours, while GM polyculture system was performed by decreasing the milkfish feed and farmers working hours. When the optimal condition is applied to the GMS polyculture system, then the business profit reaches five times, resulting in an increased profit margin of 112% with R/C becomes 134%. Meanwhile, GM polyculture system only reaches 65% business profit, 65% profit margin, and 25% R/C. The investment payback period from both polyculture systems became shorter. The application of production input efficiency on the GMS polyculture system is more prospective than GM polyculture system.

Abstract. Saputra AW, Yuda P. 2020. Low genetic diversity and no genetic differentiation between maleo hatched at coastal and inland nesting grounds in North Sulawesi, Indonesia. Biodiversitas 21: 4772-4777. Maleo Senkawor (Macrocephalon maleo), an endemic and endangered bird of Sulawesi (Indonesia), is burrow-nesting megapodes that incubate its eggs in communal nesting sites in soils heated by sun on beaches and by volcanic activity in inland. The aims of this study were to assess genetic diversity of the Maleo and examine whether those which have different nesting sites have become genetically differentiated. In total, 24 eggshell membranes of Maleo were collected from Tanjung Binerean (coastal nesting ground) and Tambun (inland nesting ground), and the DNA was extracted using silica spin-column kit. PCR was applied to amplify the hypervariable region 1 (HV1) and partial mtDNA control region of HV2 using a specific primer set designed for Maleo. The PCR products were sequenced, resulted in 612 bp, and showed 9 polymorphic sites and 9 haplotypes (H). Further sequences analysis suggested that there was no genetic differentiation between coastal nesting population and inland nesting population (Fst = 0.0009; P = 0.431). As expected, the genetic diversity of Maleo was relatively low (coastal nesting population, Hd: 0.727270, ?: 0.002377 and inland nesting population Hd: 0.848480, ?: 0.002203).

Abstract. Hanafiah DS, Safni I, Siregar LAM, Famanik RIM, Lestmi A, Matondang M. 2020. Resistance level of several soybean lines of M6 generation to stem rot disease Athelia rolfsii. Biodiversitas 21: 4537-4542.  Athelia rolfsii (Curzi) C.C. Tu & Kimbr. is a soil-borne pathogen that causes stem rot disease on plants. The attack is one of the causes of low soybean productivity hence induction of plant resistance is needed to overcome these problems. Mutagenesis is one of the breeding techniques for inducing genetic variability especially for disease-resistant characters in soybean. This research aimed to obtain selected soybean plant lines (Glycine max L. Merr) of M6 generation based on resistant character against stem rot disease A. rolfsii. This research was conducted at the Laboratory of Plant Disease and research field of Faculty of Agriculture, Universitas Sumatera Utara, Medan, Indonesia and soybean planting was carried out on agricultural field, Universitas Sumatera Utara from March to September 2018. This research used augmented design. The treatments were 8 mutant genotypes derived from radiation mutagenesis, that is; Anjasmoro, Argomulyo, and Kipas Putih varieties.  The results showed that the analysis of resistant levels on M6 generation based on disease incidence resulted in 2 lines with resistant criteria to stem rot disease A. rolfsii, that is; M100A25 (5/3) and M200A11 (32/3). Observation of intensity of disease attacks showed that Anjasmoro, Argomulyo, M100A6 (31/1), and M200A12 (6/5) had the lowest resistance level compared to other genotypes. The mutant lines that had high category level of resistance are candidates for resistance lines against stem rot disease A. rolfsii.
