Abstract

Nuryanto A, Amalia G, Khairani D, Pramono H, Bhagawati D. 2018. Molecular characterization of four giant gourami strains from Java and Sumatra. Biodiversitas 19: 578-584. Giant gourami (Osprhonemus goramy) are widely distibuted across Indonesia, such Java, Sumatra, and Kalimatan which lead to the emerge of various gourami strains due to morphological differences. However, no scientific data about the relationship between morphological and genetic differences among strains. This research aimed to obtain information on molecular characteristics of four giant gourami strains from Java and Sumatra based on partial sequences of cytochrome c oxidase 1 gene. This information is vital to strengthen their taxonomic status. Caudal fin clips were sampled from each strain. Nucleotide sequencing was performed using bigdye terminator tehcnique. Pairwise Fst comparison was carried out using arlequin software, whereas sequences of divergence analysis was performed in DnaSP software. Homology of the sequences were checked with previous published data available in Boldsystem data base. Homology test resulted in 98.79 to 100% similarity to the previous published sequences. This means that all strains belonged to single species, i.e. Osphronemus goramy. This placement was supported by low-level of genetic divergences among strains. Although they have low-level genetic divergences, this value is suitable to separate each strain clearly as indicated by pairwise Fst comparison analysis and AMOVA, which showed differences among strains. However, phylogenetic tree shows that all stains formed a monopyletic group with boostratp value of 100. Phylogenetic analysis supports the placement of all strains into a single species that is O. guramy. Those morphological differences are also reflected in their genetic character, except for Tambago and Oranye strains.

Abstract

Withaningsih S, Andari CD, Parikesit, Fitriani N. 2018. The effect of understory plants on pollinators visitation in coffee plantations: Case study of coffee plantations in West Bandung District, West Java, Indonesia. Biodiversitas 19: 604-612. West Java is one of the excellent producers of the most expensive coffee in the world (Kopi Luwak). Coffee (Coffea spp.) is one of the crops that require insect pollination for fruit formation. Coffee production in Indonesia is declining in recent years despite the expansion of coffee cultivation area that increases by 2-5 times. The decline in coffee production has been associated with fewer visitations of pollinator insects. Visitations of pollinator insects can improve the quality and quantity of coffee, mainly from the abundance and diversity of pollinator insect. Abundance and diversity of pollinator insects can be improved by to providing them with flowering plants such as understory plants. This study aimed to prove the effect of the existence of flowering plants on the visitation of pollinator insects. Pollinator insects visiting coffee flowers were observed with an observation method in two observation units. The first unit was the location with understory plants while the second was the location without understory plants. The results showed that the abundance of pollinator insects visiting coffee flowers in unit 1 was significantly (P<0.05) higher than that in unit 2. However, the diversity of pollinator insects between the two locations did not differ significantly (P> 0.05).

Abstract

Nayak S, Dhua U, Chhotaray A, Samanta S, Sengupta C. 2018. Short Communication: Genetic diversity of fumonisin producing Fusarium isolates from rice using PCR-RFLP of IGS-rDNA region. Biodiversitas 19: 621-626. Fusarium verticillioides (Sacc.) and related species produce carcinogenic mycotoxin known as Fumonisins in several agricultural crops including rice. However, this principal food crop has been infected by genetically diverse Fusarium species. Odisha belongs to the coastal part of India and many popular rice varieties are in the food chain in this region. Many Fusarium species producing fumonisins have been found to be associated with these rice varieties. Hence, the genetic diversity of twenty eight Fumonisin producers and non producers of Fusarium pathogens in this region was carried out in the current study. The IGS regions of 28 Fusarium isolates (both fumonisin producing and non producing) were amplified and the PCR products were restriction digested with ECoRI and HhaI. The digested products were separated on PAGE and bands were visualized by Silver Nitrate Staining. The 28 isolates could be separated into 14 IGS haplotypes. The lowest similarity was detected to be of 33% between F40 and F47. A group containing 14 isolates represented the biggest haplotypes. The isolates in which the FUM gene had not been detected (fumonisin non producer) were in a separate group having 90% similarity with each other and placed consistently in separate branch from others. Presence of unique band for this group was observed at 1650bp where as absence of specific bands was observed at 380bp and 300bp. The result of this study indicated a high degree of genetic variation among 28 Fusarium isolates. PCR RFLP of IGS region was also found to be useful for diversity study in Fusarium.

Abstract

Nurhatika S, Ermavitalini D, Saputro TB, Apriyatmoko Y. 2018. Biodiversity and characterization of high lipid content microalgae in Porong River Estuary East Java, Indonesia. Biodiversitas 19: 627-632. Microalgae are aquatic unicellular or multicellular microscopic photoautotroph organisms. High lipid content in microalgae biomass can be used as raw material for biodiesel. Porong river estuary is one of the sites of industrial waste disposal. The polluted waters considered will affect the lipid microalgae metabolism. The main research aims are to isolate and characterize of high lipid content microalgae found in Porong river estuary through the selection of qualitative lipid content. Sampling was conducted at three different stations. Isolation was conducted in solid agar media enriched with Porong River Estuary sterile water and using streak plate method. The isolated microalgae were characterized using a light microscope and to be matched with identification books. The lipid content was determined qualitatively by coloring the isolated-microalgae cells with Nile Red, an intracellular lipid dye then observed its luminescence color under a fluorescence microscope. Several genera of microalgae that can be isolated in this study are Oscillatoria, Nitzschia, Merismopedia, Navicula, Nannochloropsis, and Melosira. The results of qualitative lipid analysis show that the genus Nannochloropsis and Nitzschia have high intracellular lipid accumulation.

Abstract

Nusantara RW, Aspan A, Alhaddad AM, Suryadi UE, Makhrawie, Fitria I, Fakhrudin J, Rezekikasari. 2018. Peat soil quality index and its determinants as influenced by land use changes in Kubu Raya District, West Kalimantan, Indonesia. Biodiversitas 19: 585-590. Tropical peatland is continuously damaged in large area in Indonesia, caused by deep and wide drains which change the ecosystem. This research was conducted to evaluate the soil quality index (SQI) based on peatland use. The research was conducted in Kubu Raya District, West Kalimantan Province, in secondary peat forest, shrubland, oil palm plantation and corn field. The variables observed in this research were subsidence, water-table level, depth of peat, bulk density, water content, porosity, organic carbon, total nitrogen, total potassium, cation exchange capacity, base saturation, ash content, available phosphorus, and exchangeable calcium, magnesium, sodium, C/N ratio and soil acidity. The results showed that SQI in secondary peat forest, shrubland, corn field and palm oil plantation were 0.40, 0.37, 0.37 and 0.37 respectively. The stepwise regression analyses showed that the variables influencing SQI were the depth of peat, water-table level, and ash content. Secondary forest had the highest level (0.74) for the depth of peat with 509 cm depth while the other sites had average level (0.41-0.43) with 108.4 cm-115.5 cm mean depth. SQI of peatland increased with the increasing depth of peat and ash content. The differences showed that land use change of peatland, from forest to plantation area would decrease its SQI.

Abstract

Budiasa IW, Santosa IGN, Ambarawati IGAA, Suada IK, Sunarta IN, Shchegolkova N. 2018. Feasibility study and carrying capacity of Lake Batur ecosystem to preserve tilapia fish farming in Bali, Indonesia. Biodiversitas 19: 613-620. Lake Batur in Bangli District was potential for fishery development up to 5% of the total water area. Currently the lake area used for fishery was only 6.28 ha, leaving the area up to 77.07 ha potential for fishery development. Tilapia (Oreochromis niloticus) was the most abundant fish in the lake. This research aimed to evaluate the financial feasibility of tilapia fish farming with Floating Net Cages (FNC) technology within the lake and to assess its carrying capacity for the tilapia aquaculture. Discounted investment criteria were used to test farm survey data from 30 tilapia fish growers at top three villages which had the largest number of FNC. Six water samples were taken using deep water sampler at three sampling points were analyzed to see a number water chemistry and physics condition. The results showed that economic life of a FNC was financially feasible as indicated by the positive Net Present Value (NPV), Internal Rate of Return (IRR) was greater than 9% and Net Benefit Cost Ratio (Net B/C) was greater than one; and however the water quality as indicated by value of TDS, NO2, BOD, Total-P, NH3, and P-PO4 exceeded the maximum limit of water quality criteria class II based on Government of Indonesia Regulation No. 82/2001. Thus, FNC should not be more expanded within the lake due to water pollution of the lake.

Falah S, Sari NM, Hidayat A. 2018. Decolorization of Remazol Brilliant Blue R by laccase of newly isolated Leiotrametes flavida Strain ZUL62 from Bangka Heath Forest, Indonesia. Biodiversitas 19: 633-639. The use of microbial enzymes seems to be an appropriate approach to neutralize synthetic dyes, providing an eco-friendly and cost-competitive alternative solution for treating industrial effluents. The objective of this research was to select the most potential fungal isolate with high laccase activity to decolorize Remazol Brilliant Blue R (RBBR) synthetic dyes. The isolation of fungal body and sampling of wood decay specimens were conducted in six different locations in heath (kerangas) forest of Bangka Belitung, Indonesia. In the present study, a total of 13 isolates were screened by using indicator plate method and for their enzyme activity. The preliminary screening was done to screen ligninolytic fungi. Then the primary screening using various indicator compounds was conducted to select laccases-producing fungi. The enzyme activity assay was performed to select fungal isolate with the highest activity. We found that the most potential fungi belonged to Leiotrametes flavida Strain ZUL62, which had been confirmed by molecular identification using 5.8S rDNA/ITS analysis. In addition, the laccase from Leiotrametes flavida Strain ZUL62 could decolorize RBBR, exhibiting a high rate of decolorization rate of 62% without any mediator within 24 h of incubation. To our best of knowledge, this study represented the first report about Leiotrametes flavida Strain ZUL62 and its potential laccase enzyme for dyes effluent treatment.

Suranto, Syahidah AT, Mahadjoeno E. 2018. Variation of morphology, anatomy and nutrition contents of local cultivar mentik rice based on the altitudes at Ngawi District, East Java, Indonesia. Biodiversitas 19: 652-659. The purposes of this research were to examine the variation in morphology, anatomy and nutrition contents of rice plants grown at three different altitudes at Ngawi District, East Java, Indonesia. The plant samples were collected from three different altitudes (200, 500 and 900 m asl. respectively). The morphological characters of leaf, root and stem were used in this examination, while Paraffin method was employed to look at the anatomical appearances. To look at the content of lipids and proteins, Soxhlet and Kjeldahl methods were used, while the Iodocolorymetre method was chosen to test the amylose content. Randomized Complete Block Design (RCBD) with one factor, namely altitude was used in this research. Morphological and anatomical characters and nutrition contents of rice plant were analyzed using one way of ANOVA. The results showed that the length and diameter of roots, plant height and also stem diameter were declining due to a higher altitude. On the other hand, the length of leaf, the number of roots, the total number of stomata and also the ratio of length per diameter of stomata increased, and so did the number of aerenchyma space roots and stems. In general, there was a tendency of decreasing amylose and protein contents due to higher altitudes.

Abstract

Mutaqin AZ, Fatharani M, Iskandar J, Partasasmita R. 2018. Utilization of Araceae by local community in Cisoka Village,  Cikijing Sub-district, Majalengka District, West Java, Indonesia. Biodiversitas 19: 640-651. Various species of Araceae plants are widely used by the tribes of Sunda as food. However, cultivation is increasingly rare inWest Java region, and is found in some places only. One area where many people still grow Araceae plants is Cisoka Village, Cikijing Sub-district, Majalengka District, West Java Province, Indonesia. This paper aims to explain the reason for the cultivation of Araceae by the local community in the Village of Cisoka. This study used a combination of qualitative and quantitative methods, but the former was used more than the latter The primary data were collected through structured and semi-structured interviews, participant observation, exploration, and plant sample collection. The data were analyzed descriptively with emic and ethic approaches. The results of the study showed that 20 species and 13 varieties (landraces) of Araceae plants were used by the community. The parts of plant traditionally used by the commumity were tuber, petiole, and leaf. The utilization of the Araceae plants were categorized into 4 main functions, namely, as food, medicine, decoration, and fish feed. The species of Araceae were commonly cultivated in various agroecosystem types, mainly home gardens, gardens, and rice fields.

Abstract. Sapari I, Perwitasari-Farajallah D, Utami Atmoko SS. 2019. The Bornean orangutan (Pongo pygmaeus wurmbii) density in a logging concession of Hulu Belantikan, Central Kalimantan, Indonesia. Biodiversitas 20: 878-883. The Bornean orangutan is currently categorized as a critically endangered species. It is found in natural forests in Borneo, where about 78% of the total population is found outside protected areas, of which 29% is in logging concessions. This study aimed to analyze the density of the orangutan population and the abundance of fruiting plants in a logging concession and Protection Forest (Hutan Lindung) in the Hulu Belantikan forests in Lamandau District, Central Kalimantan, Indonesia. Research and data collection was conducted between December 2013 to October 2014. Orangutan population density was calculated using line transect methodology based on nest counts. Abundance of fruit plants was calculated using the fruit trail method. The highest orangutan density, 4.8 individuals/km2, was found in Protection Forest; and the lowest density, 0.4 individuals/km2, was in [Sopanan] the 2013 logging block. Observations in the logging area indicated that selective logging could alter the structure and gap of the canopy and reduce the proportion of large trees. Changes in forest structure resulted in negative effects on the density of the orangutan population. The remaining degraded forests can still be a valuable resource for the orangutan. As long as the disturbance is not intensive, orangutans will retain access to the less disturbed forest nearby and to forests that are still connected to primary forests. The existence of Protection Forest and old logged-over forests around logging blocks are very important for conservation, providing refugia for orangutans and other species when logging occurs.
