Abstract. Ariawan I, Herdiyeni Y, Siregar IZ. 2020. Short Communication: Geometric morphometric analysis of leaves venation in Shorea spp. for identification using Digital Image Processing. Biodiversitas 21: 3303-3309. Shorea is one of the genera of the Dipterocarpaceae family which consists of more than 190 species. Massive exploitation of forests has threatened the sustainability of Shorea in nature. A total of 156 species has been listed on the IUCN (International Union for Conservation of Nature) red list. From the 156 species, 59.6% are in the critically endangered category, so urgent conservation is needed. However, during collection of Shorea at the seedling phase for conservation  purposes, it is often difficult to distinguish among them that can cause errors in their collection process. To avoid these errors, identification needs to be done, usually based on plant  leaf and flower  morphology. Leaves are easier because they have the main features that distinguish each plant species, one of which is the venation structure. Geometric morphometric techniques are a modern approach recognized as useful for the identification of species in many plants. Geometric morphometrics analyzes the position of the venation point using coordinate geometry values. This research was aimed to extract venation features of Shorea leaves using a geometric morphometric approach. The extraction process result in some features, such as straightness, different angle, length ratio, scale projection, and secondary nerves. On extracted features, an analysis was then performed to find out the best features in classifying species of Shorea spp. The results of this study indicated that the geometric morphometric approach could extract the value of the features of straightness, different angle, length ratio, scale projection, and secondary nerves. The secondary nerve feature is the best feature because it can distinguish between fourcommonly planted species of Shorea spp. (S. acuminata, S. leprosula, S. ovalis, and S. selanica). By using the support vector machine classification technique to identify species of Shorea spp., the classification results obtained an average accuracy of 84.46%.

Abstract. Musyarofah N, Susanto S, Aziz SA, Suketi K, Dadang. 2020. The diversity of ‘kristal’ guava (Psidium guajava) fruit quality in response to different altitudes and cultural practices. Biodiversitas 21: 3310-3316. The current study aimed to compare the quality of ‘kristal’ guava fruit harvested from different altitudes under different cultural practices. The study was conducted from January to March 2019. Four treatments were examined, i.e., fruit from low altitude-intensive cultural (LI), low altitude-less intensive cultural (LI), middle altitude-intensive cultural (MI), and middle altitude-less intensive cultural (ML). All treatments were arranged in a completed randomized design and each treatment had five trees as replicates The findings of the study showed that there was a variation of fruit quality in response to different altitudes and cultural practices. The fruits harvested from low altitudes were significantly bigger and heavier than the fruits harvested from middle altitude, irrespective of cultural practices. With regard to fruit softness, the fruits from middle altitudes were crispier than fruits from the low altitude. The chemical qualities of the fruits, indicated by TSS/TA ratio and vitamin C, were better in guava orchard under intensive cultural practice than less intensive cultural practice. The intensive cultural practice also improved the guava fruit size as compared to the less intensive cultural practice. This finding may be attributed to pruning which is performed in intensive cultural practice. More beneficial metabolites for human health such as vitamin E and caryophyllene were found in fruit from low altitude.

Abstract. Arminudin AT, Suputa, Wijonarko A, Trisyono YA. 2020. Ultrastructure characters and partial mtDNA-COI haplotypes of Asian corn borer, Ostrinia furnacalis (Guenée) (Lepidoptera: Crambidae) from Indonesia. Biodiversitas 21: 2914-2922. In addition to the confirmation of the species of corn borer, we analyzed the relationship of Ostrinia furnacalis in Indonesia with that in other countries. Moths of O. furnacalis were collected from several areas in Java and Sumatra islands of Indonesia. Forewing and labial palpi scales were investigated under Scanning Electron Microscopy observation. A 658 bp of O. furnacalis partial COI gene sequences of 1480-2138 nucleotides were downloaded from GenBank and BOLD system databases. The ridge lamellae and window characters as unique ultrastructure characters of scale were further supported by the COI gene analysis. High similarity was observed between the Java and the Philippines specimens, but they were a different haplotype compared with Sumatra’s specimen. The results could provide the baseline data on the genetic variation of O. furnacalis in Indonesia.

Abstract. Tambunan VB, Apriyanto A, Ajambang W, Etta CE, Sahari B, Buchori D, Hidayat P. 2020. Molecular identification and population genetic study of Elaeidobius kamerunicus Faust. (Coleoptera: Curculionidae) from Indonesia, Malaysia and Cameroon based on mitochondrial gene. Biodiversitas 21: 3263-3270. Oil palm pollinating weevil Elaeidobius kamerunicus is a very important insect pollinator in oil palm plantation. However, there is still lack of information about molecular identification and population genetic study in this species. The purpose of this study was to explore the effectiveness of oil palm pollinating weevil identification using mitochondrial DNA of COI gene and to assess its genetic variation between different locations and countries. We sequenced the DNA barcode of 36 individuals of this species using the mtDNA Cytochrome Oxidase I (COI) gene to explore their genetic variation, identity and phylogenetic relationship. The COI gene sequences generated from this study were successful in identifying E. kamerunicus. Phylogenetic analysis also revealed 3 well-supported monophyletic haplogroups of E. kamerunicus population. In addition, genetic differentiation analysis revealed that most populations from Indonesia were different from Malaysian and Cameroonian populations indicating that there was a genetic variation between the population samples from these countries. The overall E. kamerunicus used in this study were geographically structured in two regions; outside Indonesia region (Cameroon and Malaysia) and Indonesia region. These results demonstrate the feasibility of using COI gene sequence for molecular identification and population genetic study of E. kamerunicus species.

Abstract. Yasmon A, Rosana Y, Usman D, Prilandari LI, Hartono TS. 2020. Short Communication: Identification and phylogenetic analysis of Corynebacterium diphtheriae isolates from Jakarta, Indonesia based on partial rpoB gene. Biodiversitas 21: 3070-3075. Indonesia is a developing country with the greatest potential of diphtheria, so accurate identification is needed to detect C. diphtheriae. The genetic relationship analysis is important to be determined so that this transmittable disease can be prevented. In this study, we reported the identification and phylogenetic analysis of C. diphtheriae based on partial rpoB gene. Twelve samples from throat swabs of diphtheria suspected patients from 2018 to 2019 were used in this study. The result of VITEK 2 ANC-Automated Testing identified that all isolates were C. diphtheriae. However, the identification based on partial rpoB gene analysis showed that only 10 out of 12 isolates were C. diphtheriae, while 2 other isolates were C. argentoratense. Of 10 C. diphtheriae strains/isolates, 2 strains were unique for Indonesia. Thus, it is needed to evaluate the accuracy of VITEK 2 ANC-Automated Testing and to conduct further comprehensive studies on the genetic relationships of C. diphtheriae strains based on multiple virulence genes, multilocus sequence typing and/or whole-genome analysis.

Abstract. Kurniawan H, Pamungkas D. 2020. The limiting factors of land suitability for sandalwood (Santalum album) in Sumba Island, Indonesia. Biodiversitas 21: 3364-3372. The land suitability assessment for sandalwood is very important for the successful cultivation and development of sandalwood (Santalum album Linn.) in Sumba Island, East Nusa Tenggara Province, Indonesia. The map of land suitability classification for sandalwood is currently available. The land suitability assessment is determined based on designated indicators and predictors. It is important to identify the most influential measures in a particular area to determine the suitable treatment to be applied to the sandalwood plant, as well as to recognize the land suitability evaluation swiftly and efficiently. This study was aimed to determine the variables of indicators or verifiers that have the strongest relationship with the land suitability class for sandalwood. Regression method was used to develop the relationship model and to determine the level of the relationship through the coefficient of determination. The result shows that P2O5 content was the most influential factor to determine the land suitability class for sandalwood in Sumba Island.

Abstract. Fatimah S, Ariffin, Rahmi AN, Kuswanto. 2020. Tolerance and determinants of drought character descriptors of the Madurese landrace bambara groundnut (Vigna subterranea). Biodiversitas 21: 3108-3116. Bambara groundnut (Vigna subterranea L. Verdc.) is legume of African origin overlooked in Indonesia. It has underdeveloped in Indonesia; for example, in East Java, it is only cultivated in Gresik, Lamongan, and Bangkalan of Madura. This plant can potentially be developed in dry lands, such as Madura as it has the ability to grow and develop well in a dry environment with low nutrient level. At present, there are sparse researches on the selection and determination of the drought-tolerant character descriptors of bambara groundnut in Indonesia. The present study used the expected lines of bambara groundnut selected from local lines of various regions in Indonesia using the nested design. The results showed that the drought stress treatment led to stunted growth of 12 bambara groundnut genotypes, including the number of leaves, plant height, canopy diameter, leaf thickness, number of flowers, number of stems or branches, number of internodes, length of leaf stems, root length, root wet weight, canopy wet weight, canopy dry weight, root dry weight, and leaf chlorophyll content. However, drought leads to a slight increase in the width and length of the stomata opening and leaf proline contents. The cluster analysis based on stress index and sensitivity index can classify 3 expected lines originating from Gresik Regency (G1, G2, G3), falling into the drought stress-tolerant category. Accumulated proline contents cannot be used as a descriptor of tolerance to drought stresses in bambara groundnut since the expected lines with an increase in proline contents in leaves during drought stresses based on the cluster analysis do not fall into the genotypic cluster tolerant to drought stresses.

Abstract. Melak A, Belayhun T, Kefyalew E, Hailu A, Mustefa A, Assefa A. 2020. Farmers' willingness to pay for Sinar donkey conservation in selected districts of Metekel and Assosa zones, northwest Ethiopia: a contingent valuation study. Biodiversitas 21: 3373-3379. A survey was conducted through single field visits and interviews with 160 respondents in selected districts of Assosa and Metekel Zones, Northwestern Ethiopia, to elicit farmers' willingness to pay for Sinar donkey conservation. Two districts namely Guba and Sherkole were purposively selected from the zones based on the availability of Sinar donkey breeds. Eight representative kebeles were selected from the two districts. A total of 160 households (each district 80 households) were selected randomly. Structured and semi-structured questionnaires were prepared to collect data on socio-economic and farming system characteristics. Descriptive statistics were employed to summarize data and average means were compared using SPSS version 23.0 software. Logistic regression was applied to see the effect of independent variables on the dependent variable. The contingent valuation method was used to know farmers' willingness to pay for conservation of the Sinar donkey breed. The average willingness to pay for the conservation was 98.25 Ethiopian Birr or 3.265US dollars for the conservation program per household per annum. The cash income of the respondents influenced the willingness to pay for the conservation program. This study supports the view that the economic valuation of donkey genetic resources can assist policymakers in setting conservation priorities.

Abstract. Lutfia FN, Isnansetyo A, Susudarti RA, Nursid M. 2020. Chemical composition diversity of fucoidans isolated from three tropical brown seaweeds (Phaeophyceae) species. Biodiversitas 21: 3170-3177. Fucoidan is a polysaccharide with high sulfate content, found in the cell walls matrix of brown seaweed. Its bioactivities vary depending on the algae species and the chemical structure. The aims of this research were to extract, purify, and characterize fucoidan from three Indonesian brown seaweed, Sargassum sp., Turbinaria sp., and Padina sp. The extraction was carried out using acid method followed by precipitation with ethanol and CaCl2, while its purification using DEAE-cellulose ion-exchange chromatography. Characterization was performed by FTIR and 1H-NMR spectroscopic analyses. Chemical components of fucoidan determined were total carbohydrates, sulfate residue, uronic acid residue, and monosaccharide components. The results revealed that the Turbinaria sp. produced highest yield of fucoidan (4.8% dry matter), followed by Sargassum sp. (2.7% dry matter) and Padina sp. (2.6% dry matter). The carbohydrate contents of Sargassum sp., Turbinaria sp. and Padina sp. fucoidan were 64.55±0.12%, 67.42 ± 0.03% and 62.90 ± 0.04% with sulfate residues of 0.013% ± 4.71; 19.47±0.002% and 0.016%±8.81; and uronic acid residues of 25.19±0.03%; 12.69±0.03% and 12.91±0.01%, respectively. Sargassum sp., Turbinaria sp., and Padina sp. fucoidans consist of fucose and some other minor monosaccharides.

Abstract. Jakaria, Ulum MF, Lestari D, Akwila S, Sihite DEWT, Priyanto R, Muladno, Sumantri C. 2020. Investigating new SNPs of CAST, CAPN and SCD genes in 5’UTR of Bali cattle. Biodiversitas 21: 2971-2976. The present investigation aims to explore specific SNPs of Bali cattle, focusing mainly on CAST, CAPN, and SCD genes in 5'UTR. DNA of Bali cattle (25 individuals) from Breeding Centre of Bali cattle in Bali Province, Indonesia, were extracted according to the protocol of GenAID. Amplification of the CAST, CAPN, and SCD genes were designed using the Primer3 program based on reference sequences (access numbers AH014526.2, AH009246.3, and AY241932). Furthermore, the PCR product was sequenced through forward primer sequencing. The data sequence results were analyzed using the Bioedit, MEGA7, Popgen 3.2, and DnaSP6 V6 programs. The results showed that SNPs were detected at g.921C>T and g.922T>G in 5'UTR for the CAST gene between the reference of GenBank AH014526.2 and Bali cattle, but it was monomorphic within the population. The high polymorphism of SNPs was found in g.232G>T for the CAPN gene and g.134A>del for the SCD gene. However, the SNP g.246C>del SCD gene was detected as monomorphic in this region. Moreover, this result shows that low nucleotide diversities (Pi) for CAST, CAPN, and SCD genes in 5'UTR of Bali cattle were 0.00422, 0.00632, and 0.00449, respectively. This finding was important for developing marker-assisted selection (MAS) to improve the meat quality of Bali cattle.
