Abstract. Rachman A. 2020. Checklist and estimation of total number of phytoplankton species in Pari, Tidung, and Payung Islands, Indonesia. Biodiversitas 21: 2446-2454. A checklist of phytoplankton species from an anthropogenically pressured ecosystem has become a necessity to study the marine ecosystem changes and to detect the presence of introduced species in the area. This study aimed to list and describe the phytoplankton community in the Tidung, Pari, and Payung Islands and to estimate the total number of phytoplankton species in those islands. Sampling was conducted in May 2019 in 10 sites, consisted of 5 sites around Pari Island, 1 site next to Payung Island, and 4 sites around Tidung Island. As many as 150 species of phytoplankton, consisted of 109 species of diatoms, 38 species of dinoflagellates, 3 species of cyanobacteria, were recorded in this study. However, up to 47 phytoplankton species were estimated to be missing from the current sampling effort. Three diatom species, Chaetoceros curvisetus, Chaetoceros distans, and Chaetoceros affinis were the most abundant and most common species in the studied areas. Dinoflagellates were found in low density and have limited distribution compared to diatoms. Tripos trichoceros, Tripos fusus, and Tripos macroceros were the three most common dinoflagellates in the studied islands. Several notable harmful species, such as Pseudo-nitzschia spp., Alexandrium sp., Tripos furca, Cochlodinium sp., Dinophysis miles, Prorocentrum lima, and Noctiluca scintillans, were present albeit with low cell density. However, concern on future blooms of those harmful species in the greater water regions (i.e. Seribu Island or Jakarta Bay) should be noted, as it might cause environmental damages, including a shift in species dominance and disappearance of some native phytoplankton species from the ecosystem in the future.

Abstract. Trianto M, Purwanto H. 2020. Morphological characteristics and morphometrics of Stingless Bees (Hymenoptera: Meliponini) in Yogyakarta, Indonesia. Biodiversitas 21: 2619-2628. Stingless bees (Apidae: Meliponinae) are eusocial insects living together in a colony with a highly organized system. Also, these bees have morphological and morphometric characters that vary among species, islands, and environmental types. This paper described morphological characteristics and morphometric study of stingless bees from the Special Region of Yogyakarta Province, Indonesia. There were seven species of stingless bees found in the Special Region of Yogyakarta, namely Tetragonula laeviceps, T. iridipennis, T. biroi, T. sapiens, T. sarawakensis, Lepidotrigona terminata, and Heterotrigona itama. The morphometry of the stingless bees obtained in this study has varying sizes compared to the same species that have been reported elsewhere. In this study, we described the morphological and morphometric characteristics of the seven species of stingless bees in the Special Region of Yogyakarta Province, Indonesia, and presented the PCA analysis to figure out the grouping characters in order to determine its diagnostic characters.

Abstract. Mahmoud HHA, Sastranegara MH, Kusmintarsih ES. 2020. Short Communication: The lifecycle of Neocaridina denticulata and N. palmata in aquariums. Biodiversitas 21: 2396-2402. The study on the life cycle of Neocaridina spp. is important because it plays a major role in the economy and trade between countries. However, there is a lack of sufficient studies on this particular topic. One of the factors that influence Neocaridina spp. life production is its life cycle and the associated water parameters. The objectives of this study were to conduct, observe, and record the life cycle of Neocaridina denticulata and N. palmata and the associated with water parameters (temperature, pH, ammonia, nitrite, and oxygen) in the aquarium. The results showed that there was no difference in the life cycle stages between the two shrimp species. Both species reached the first sexual maturity stage of the life cycle at 75 days, with the maximum body length of the mature shrimp ranging from 2.30-3.00 cm. The eggs became larvae in 15 days, larvae reached the juvenile stage after 60 days, and the juvenile became mature in 15 days. The number of eggs was influenced by the body size of the female shrimps; smaller females produced fewer eggs. Optimal water quality varies by species and must be monitored to ensure growth and survival. The temperature range in this study was 25-28°C and the pH was 6.5-8.0. The ammonia level was in the range between 1.21 and1.72 mg/L, the nitrate was between 0.06 and 7.91 mg/L, and the oxygen was around 5.5-7.9 mg/L. All of the water quality parameters in this study are within the acceptable range for Neocardina cultivation.

Abstract. Hasanah R, Saepuloh U, Perwitasari-Farajallah D, Sinaga W, Hastuti Y, Sajuthi D. 2020. Genetic characterization based on the D-loop MtDNA and the TSPY genes of the Dwarf Siamang (Hylobates klossii) of Mentawai Island, Indonesia. Biodiversitas 21: 2854-2861. Hylobates klossii is an endemic primate on the Mentawai Island, Indonesia that categorized as endangered species due to fragmentation, illegal hunting, and habitat loss. This study aimed to analyze the genetic characterization of H. klossii based on maternal and paternal lineages. The samples were collected from TSI (Bogor, Indonesia) cage consist of two males and two females (blood and fecal of four individuals) and Siberut Island, Mentawai, West Sumatra, Indonesia from one unknown gender (one individual fecal sample). PCR amplification was carried out on DNA and cDNA samples using specific primers for D-loop MtDNA and TSPY genes. The amplicon was analyzed with MEGA-7. The dimensional structure model of the TSPY protein was determined using I-TASSER and visualized with PyMol. The maternal analysis showed five samples consisted of four haplotypes revealed that Nam-nam and April were identic with 0% genetic distance. It’s revealed that Nam-nam and April were mother and son. The paternal analysis of two H. klossii males revealed that April was the closest relative to H. muelleri (99.56% identity) and Gou-gou to H. klossii (100% identity). Characterization of partial TSPY gene (990 bp) of April and Gou-Gou indicated four amino acids mutation, causing the shift in-amino acid structure position. The results assumed that April was a cross-breeding between H. klossii female and H. muelleri male. This genetic characterization is expected to support the conservation efforts through recommendations for good management in H. klossii preservation.

Abstract. Widiastuti A, Karlina ML, Dhanti KR, Chinta YD, Joko T, Suryanti, Wibowo A. 2020. Morphological and molecular identification of Fusarium spp. isolated from maize kernels in Java and Lombok, Indonesia. Biodiversitas 21: 2741-2750. Fungal contamination of maize is a serious problem in Indonesia. Fusarium spp. infect maize in the field will be continuing to contaminate in the post-harvest period even though disease symptoms are not always emerged. Some Fusarium spp. produced mycotoxins which are harmful to human and animal health. Aims of this research were to reveal the presence of Fusarium spp. from both symptomatic and unsymptomatic maize, and to identify them based on morphological characteristics and molecular analysis. Samples of maize were collected from maize cultivation areas in East Java (EJ), Central Java (CJ), West Java (WJ), Yogyakarta Special Province (DIY), and Lombok, West Nusa Tenggara. Fusarium spp. were isolated in a single spore method and cultured in potato dextrose agar (PDA) medium for morphological identification of macro-and microconidia. Molecular identification was conducted by PCR assay using species-specific primers. Furthermore, unidentified species were analyzed by DNA sequence. This research found four species of mycotoxigenic Fusarium isolated from maize-based on molecular identification, which were Fusarium verticillioides (15 isolates), F. proliferatum (6 isolates), F. graminearum (1 isolate) and F. asiaticum (1 isolate). This research showed a novel report of F. asiaticum infection on maize kernel in Indonesia.

Abstract. Maghfiroh CN, Putra ETS, Dewi HSES. 2020. Root detection by resistivity imaging and physiological activity with the dead-end trench on three clones of cocoa (Theobroma cacao). Biodiversitas 21: 2794-2803. Indonesia is one of the largest cocoa production countries in Southeast Asia, but has low average productivity (982 kg/ha) based on Indonesian Plantation Statistics (2017). Productivity increase effort by giving dead-end trenches that applied to collect organic material, accommodate surface runoff sediments, prevent erosion, and maintain nutrient availability. Dead-end trench had an impact on root cutting and improve rooting. Clone is very influential on cocoa (Theobroma cacao L.) yield. The superior clones recommended are clones RCC-70, RCC-71, and KKM-22, which have high productivity and are resistant to pests and diseases. The objectives of this research were (i) to detect the presence of roots by resistivity imaging (ii) to study the effects of dead-end trench application on physiological activities of cocoa leaves and yields of three clones (RCC-70, RCC-71, and KKM-22); (iii) to determine which cocoa clone (s) performed a significant yield increase with the application of dead-end trench. Research was conducted in August 2018-April 2019 at PT. Pagilaran cocoa plantation in North Segayung Production Unit, subdistrict Tulis, Batang, Central Java. The experiment was arranged in a randomized complete design with two factors and three blocks as replications. The first factor was dead-end trench application (with or without dead-end trench application) and the second factor was cocoa clones (RCC-70, RCC-71, and KKM-22). This study showed that dead-end trench applications affected plant roots based on the interpretation results of geoelectric-resistivity measurements. Dead-end trench application significantly affected chlorophyll a, stomatal conductance, transpiration, and H2O leaf content. Dead-end trench application has no significant effect on the content of chlorophyll b, total chlorophyll content, nitrate reductase activity, stomatal density, CO2 leaf content, and photosynthesis rate.

Abstract. Cudera RB, Razon BC, Millondaga KJI. 2020. Cultural and ecological significance of Odonata (Insecta) to the T'boli of Lake Sebu, Mindanao, Philippines. Biodiversitas 21: 2536-2554. Lake Sebu in Mindanao, Philippines, covered by the Allah Valley Protected Landscape, is home to the T'boli ethnolinguistic group. This study focuses on the cultural and ecological significance of the Odonata (insect order of dragonflies and damselflies) to the T'boli people who are known to have a close connection to their natural environment. According to the T'boli who participated in-depth interviews and focus group discussions, the Odonate larvae of Family Libellulidae and Aeshnidae known as Kmimi and Ogong El respectively are handpicked by the village members as a food source shared in the community when resources are scarce. The Odonata larvae are also used to cure illnesses and are locally believed to be important components for a love potion. In agriculture, T'boli farmers utilize the adult form of Odonata known as Klowong as natural biocontrol agents. Moreover, the Odonata larvae are prominent images in T'boli oral literature, specifically folklore and lullabies, teaching the children the importance of maintaining a harmonious relationship with nature. The results show that the presence of endemic species of Odonata indicates a healthy freshwater environment in the area; thus, studies on the sustainable use and conservation measures of the Odonata should be conducted.

Short Communication: The presence of extended-spectrum beta-lactamase (ESBL) producing Escherichia coli on layer chicken farms in Blitar Area, Indonesia. Biodiversitas 21: 2667-2671. This study was aimed to determine the incidence of Extended-Spectrum Beta-Lactamase (ESBL) producing Escherichia coli on layer chicken in Blitar area. This was a cross-sectional study with a total of 205 cloacal swabs of layer chicken taken randomly. The sample was in isolation identification on MacConkey media and ESBL confirmation test produced by Escherichia coli was then carried out by the Double Disc Synergy Test (DDST) method and the VITEK® 2 Compact Automated System method. This study showed that 185 (90.24%) isolates of positive Escherichia coli from a total of 205 samples of cloacal swabs of the layer chicken. The incidence of ESBL-producing Escherichia coli in cloacal swabs on layer chicken with the Double Disc Synergy Test (DDST) method and the VITEK® 2 compact automatic method was 13 (7.03%). Results in this study indicated that layer chicken has potential as reservoir for spreading ESBL to public health and needs strict hygienic measures to prevent their transmission to humans.
