Abstract. Pramono AA, Syamsuwida D, Putri KP. 2019. Variation of seed sizes and its effect on germination and seedling growth of mahogany (Swietenia macrophylla). Biodiversitas 20: 2576-2582. To get high-quality seeds, the size of seed is often suggested to be criteria of selection in seed collection. However, the size is not always effective to be used as a basis for seed selection. The study is aimed to determine the variation of mahogany (Swietenia macrophylla) seed sizes and its effect on the germination and seedlings growth. The fruits were collected from stands of mahogany in Jonggol and Parung Panjang, Bogor District, Indonesia. The seeds were grouped into 5 classes based on seed size. The observation was conducted on seed viability of each size class as well as the growth of seedlings until 3 months old. The results showed that the seed size of mahogany was affected by position of the seeds inside the fruit, the mother trees, and fruit size. The seeds size of < 6 cm long had significantly lower germination rate and capacity than those seeds of more than 6 cm long. The size of seeds affected the initial growth of seedlings, but did not influence the subsequent growth of seedling after 3 months old. The selection of seeds was done by removing the seeds of less than 6 cm long.

Abstract. Akroman R, Nurhayati N, Suwasono S, Jayus J. 2019. Phenotypic and genotypic characteristics of exopolysaccharide-producing fungi as a source of food additives. Biodiversitas 20: 2468-2474. As the demand for materials suitable for edible film in food processing is increasing, the exploration of exopolysaccharide (EPS) producing fungi is important. Some fungi had been reported to produce extracellular polysaccharide having rheological properties potential as thickener and or plasticizer useful for edible film raw material. Therefore, this study was focused on isolation and identification of EPS-producing fungi from the plantation area surrounding the University of Jember, Indonesia. The fungal isolate obtained was morphologically identified based on mycelia and spore type, while its genotype was determined using ITS1 and ITS4 primers. The optimum initial culture pH for EPS production was measured using shake flask culture fermentation. The rheological properties of the EPS were determined using Brookfield viscometer, and surface structure of EPS was observed using a scanning electron microscope (SEM). The result showed that the mycelium of the isolate was reddish-brown and septated, its spores were formed as conidiospores. Internal Transcribed Spacer (ITS) sequence of the fungus showed that the isolate is a new species. Therefore, it was designated as C. lunata isolate RJ01. Optimum initial pH for EPS production was pH 6.0, achieved after 5 days fermentation yielded 2.6 g L-1 of EPS. The EPS from C. lunata isolate RJ01 have no cytotoxic activity on vero cell. The rheological behaviour of C. lunata EPS was viscous, and its surface structure of EPS was compact indicating its potency as thickening agent and plasticizer, a material required for edible film formation in food industries.

Abstract. Nopriawansyah N, Rauf A, Kusumah YM, Nurmansyah A, Koesmaryono Y. 2019. Genetic variation among the geographic population of Cassava mealybug Phenacoccus manihoti (Hemiptera: Pseudococcidae) in Indonesia inferred from mitochondrial COI gene sequence. Biodiversitas 20: 2685-2692. Cassava mealybug, Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae) is an invasive pest native to South America. Research was conducted with the objective to study genetic variation of cassava mealybug from different geographic areas in Indonesia. Thirty-six samples of cassava mealybugs were collected from eight different population locations. Genomic DNA was extracted from individual specimens of P. manihoti using gSYNC DNA Extraction Kit from Geneaid Lot No. FB221707. PCR amplification using primary CO1 gene showed the target position as long as 518 bp. Analysis of homology from eight populations revealed eight haplotypes in Indonesia with different variable sites. Genetic distance analysis was done by calculating base pair differences in each population. The percentage of genetic distance between populations was 0.0000% -0.00409%. The results of the analyst using the Kimura-2 parameter showed that the population was divided into 2 clusters. The highest haplotype (Hd) diversity value was 0.8333, while the lowest was zero (Hd = 0). The highest nucleotide diversity (?) was 0.00225 and the lowest was 0.000000. The genetic distance and nucleotide diversity were low because P. manihoti was thelytoky parthenogenesis.

Abstract. Rejeki S, Middeljans M, Widowati LL, Ariyati RW, Elfitasari T, Bosma RH. 2019. The effects of decomposing mangrove leaf litter and its tannins on water quality and the growth and survival of tiger prawn (Penaeus monodon) post-larvae. Biodiversitas 20: 2750-2757. Shrimp farming in Demak, Indonesia is often practiced in silvo-aquaculture systems in which mangrove trees are planted on pond bunds. As such, mangrove leaves and its substrates may have impact on penaeid shrimp production. In this area, mangrove re-growth proceeded with Avicennia marina while planting is mostly done with Rhizophora apiculata. We compared the effects of decomposing fresh leaves of A. marina and R. apiculata on water quality and on the performance of Penaeus monodon postlarvae (PL). A hundred of PL21 (postlarvae aged 21 days with weight of 0.28 g) were stocked in each of 30 aerated tanks containing 800 liters of brackish water (salinity of 21 ppt) for 37 days. Five treatments with three replicates for each mangrove species were assigned by adding into the tanks of 0.125, 0.25, and 0.5 g L-1 of air-dried leave, 0.125 of g L-1 minced leave and 0.125 g L-1 of leachate of minced leaves. The PLs were fed 3 times daily with pellets at 10 % of initial total body weight. Water quality parameters were recorded daily. Tannin, H2S and NH3-N concentrations were measured every ten days. Prawn's body weight (BW) was measured and specific growth rate (SGR, % day-1) and survival rate (SR, %) were calculated after the end of experiment. Results were analyzed with ANOVA and Pearson's correlation. The results showed that tannin in decomposing mangrove leaf litter up to a concentration of 0.5 mg g-1 did not have a significant effect on water quality and on the growth and survival of P. monodon PL. However, increasing leaf litter concentrations showed an increase in NH3-N concentration due to organic matter degradation. The accumulation of NH3-N may have caused the slow growth of shrimp PL in A. marina treatment. Shrimp PL in leaf litter leachates treatment has a higher growth rate than those PL in regular leaf litter in relation to nutritional value. Survival and growth varied from 62 ±14 to 70 ± 8% and 3.1±2.1 to 5.5±1.2% day-1, respectively. Although decomposing mangrove leaves of A. marina and R. apiculata had no toxic effects on P. monodon PL up to a concentration of 1.25 g L-1, but causing severe mortality for shrimp in tanks without water exchange. As a conclusion, the present of mangrove leaves in brackish water ponds with insufficient water exchange can be harmful to shrimps. However, if the water exchange is good, decomposed mangrove leaves can become organic fertilizer that beneficial for the growth of natural food for the shrimps

Abstract. Sulistyawati, Roeswitawati D, Ibrahim JT, Maftuchah. 2019. Genetic diversity of local sorghum (Sorghum bicolor) genotypes of East Java, Indonesia for agro-morphological and physiological traits. Biodiversitas 20: 2503-2510. Sorghum (Sorghum bicolor (L.) Moench) has great potential to be cultivated because it has extensive adaptability, tolerant to drought and puddles, can produce on marginal land and relatively resistant to pests and diseases. To meet the food requirement, sorghum can be grown in Indonesia as an alternative food source other than rice. This study aims to obtain information on the agro-morphological and physiological characters of nine local sorghum genotypes in East Java, Indonesia so that they can be used as parents in improving the nature of varieties. The experiment was conducted in a Randomized Block Design, using nine local sorghum genotypes from East Java in three replications. The nine local sorghum genotypes are Sb.Pas, Sb.Lmg 1, Sb.Lmg 2, Sb.Tbn, Sb.Spg 1, Sb.Spg 2, Sb.Tag 1, Sb.Tag 2 and Sb.Jbg. The result showed that nine genotypes that are characterized have a variety of morphological (quantitative and qualitative), agronomic and physiological characters. According to the whole characters observed, there are five genotypes that are recommended for breeding programs, namely Sb.Lmg 1, Sb.Tbn, Sb.Spg 2, Sb.Tag1 and sb.Tag2. This can be proved by the morphological character, genotype Sb.Lmg 1, Sb.Tbn, Sb.Spg 2, Sb.Tag 1 and Sb.Tag2 have a high value of Agronomy character, genotype Sb.Tbn, Sb.Tag 1 and Sb.Tag 2 noted highest production acres-1 harvest age of genjah and medium; the Physiology character, high protein and carbohydrate substances reached by the Sb.Lmg 1 genotype, Sb.Tbn and Sb.Spg 2.

Abstract. Nuryanto A, Komalawati N, Sugiharto. 2019. Genetic diversity assessment of Hemibagrus nemurus from rivers in Java Island, Indonesia using COI gene. Biodiversitas 20: 2707-2717. Green catfish (Hemibagrus nemurus) is a popular freshwater fish that highly exploited in almost all the rivers in Java Island. The exploited population tends to have low genetic diversity. Meanwhile, separated populations might lead to a genetic difference among the river populations. This study aims to investigate the genetic diversity and population variation of H. nemurus collected at eleven rivers across Java Island. The analysis based on 465 bp fragment of the cytochrome c oxidase 1 gene from 140 individuals. Analysis of overall populations proved that H. nemurus had a high gene diversity (h= 0.935±0.016) and nucleotide diversity (? = 0.073±0.036). Within population analysis also showed that H. nemurus populations showed high levels of gene diversity (h= 0.338±0.128 to 1.000±0.022) and nucleotide diversity (? =0.001±0.001 to 0.071±0.038). Those diversity values indicated that H. nemurus had high level of genetic diversity, except for the Citanduy population. Population comparison showed that significant genetic differences observed among populations (p= 0.000 for both variance component and Fst-value). However, pairwise comparison analysis indicated complex pattern of population differentiation. The high genetic diversity and complex pattern of population differentiation have important implication for H. nemurus conservation in Java Island.

Abstract. Suranto, Wahyuni D, Edy Purwanto E. 2019. Evidence of pollen features and peroxidase isozymes in their morphological complexity of ten local cultivars of sweet potato from Indonesia. Biodiversitas 20: 2511-2518. Sweet potato (Ipomoea batatas Lam) has been recorded to have many cultivars and variations in the morphological characters not only for the leaves but also for the tubers. Sweet potatoes had economically significant role, especially as an additional food due to its high content of carbohydrate and other nutrient values. In order to test whether the morphological variation in this species was also expressed at the micro character; such as pollen morphology and enzyme activity, ten sweet potato cultivars were used in this study. The morphological characters such as shape and structure of the pollen features were examined using Scanning Electron Microscopy (SEM). Accordingly, Polyacrylamide Gel Electrophoresis (PAGE) was used to look-at the banding pattern of peroxidase isozymes. Morphological characters of leaves, flowers, and tuber were observed qualitatively both for the typical shape and colors. More detail of flower shapes was drown manually especially their petal edges. The results showed that there was variation among the ten sweet potato cultivars confirmed not only on their morphological characters but also the isozyme banding patterns of ten cultivars tested. At least, two cultivar Antin 3 and Papua Solossa had uniques characters especially the purple stem and yellow tuber and dark skin on the tuber, respectively. In addition, the structural analysis of pollen showed that Beta 1 cultivar has very large pollen; 116,50 ?m (axis polar) and the contour surface of exine pollen was concave with the aperture shape and ornamentation were prolate spheroidal and echinate respectively. This unique character was also shown by its peroxidase isozyme bands. Eleven bands of leaf and 13 bands of stem samples were detected respectively. The typical Rf values of 0.31, 0.48 and 0.41 were detected for the leaf, while for stem samples were 0.14, 0.20 and 0.26. The Beta 1 cultivar showed very thick bands in between Rf values of 0.13 and 0.26. Meanwhile, the unique band pattern of Papua Salosa was the absence of band at 0.38.

Abstract. Alcala AA, Delos Angeles MD, Buot Jr IE. 2019. Fern species diversity across various land use types of Mt. Makiling, Luzon Island, Philippines. Biodiversitas 20: 2437-2445. Mt. Makiling of Luzon Island, Philippines is home to many living organisms including ferns and fern allies which are one of the important understory vegetation in many forest communities and having various economic uses like food, medicine and ornamentation. This study identified fern species found in various land use types across the northeastern slope of Mt. Makiling, Los Baños, Philippines. The plot technique was employed using a 20x20 meter quadrat. Three (3) 5x2 subquadrats were randomly distributed within the established quadrat. Fern specimens were identified (sensu PPG, 2016) and measured. Samples were collected for herbarium voucher deposited in the PBDH. A total of 28 fern species with 22 genera from 14 families were found across land use types. Identified land use types were: i) Mahogany (341 m asl.); (ii) Agriculture (355 m asl.); (iii) Buffer zone (365 m asl.); (iv) Agroforest (368 m asl.); (v) Roadside (455 m asl.), and (vi) Forest (482 m asl.). The most represented fern families were found out to be Thelypteridaceae (5 spp), Dryopteridaceae (3 spp), Polypodiaceae (3 spp.), Pteridaceae (3 spp), Aspleniaceae (2 spp), Dennstaedtiaceae (2 spp), Selaginellaceae (2 spp.) and Tectariaceae (2 spp.). On the other hand the families Schizaeaceae, Lindsaeaceae, Davalliaceae, Nephrolepidaceae, and Marratiaceae are comprised of one species only. Pteris blumeana C. Agardh and Tectaria crenata Cav. were found only in buffer zone area. Dennstaedtia philippinensis Copel., Lygodium circinnatum (Burm. f.) Sw. and Microlepia sp., were found only in agroforest area; Sphaerostephanos unitus (L.) Holttum found only in agricultural; Bolbitis heteroclita (C. Presl) Ching and Microsorum membranifolium (R. Br.) Ching were found in roadside while Asplenium tenerum G. Forst. , Christella sp., Lindsaea fissa Copel. and Nephrolepis cordifolia (L.) C. Presl were found in forest area. Pneumatopteris nitidula (C. Presl) Holttum. is a dominant fern species found in agriculture and mahogany plantation area. There is a need to document fern species along with its population across land use types in order to utilize ferns as plant indicators due to their vulnerability to changes in environmental conditions. These results can shed light on the appropriate strategy for the conservation and management of ferns in Mt. Makiling.

Abstract. Saharjo BH, Hadiwijoyo E. 2019. Short Communication: Land cover changes from 2005 to 2015 in Mantangai area of Dayak Ngaju, Central Kalimantan, Indonesia. Biodiversitas 20: 2596-2602. Forest and land fires in Indonesia are well recognized, directly or indirectly, as the main contributors to deforestation and greenhouse gas emission related to the global climate change. Usually, local peoples are blamed for those fires especially when negative impact occurred. Fortunately, not all of the local peoples do the same thing as it is shown by Dayak Ngaju in Block A of ex-Mega Rice Project (Ex-MRP) Project area located in Mantangai sub-district Kapuas district, Central Kalimantan Province, Indonesia, where this research was conducted. The objective of this study was to know land the cover changes related to the use of fire for land preparation, and how the Dayak Ngaju people implement their knowledge and experience in the field. This objective was achieved by analyzing satellite images of Landsat 7 and 8 for a period of time starting from 2005 to 2015. Results of the research showed that the local people started clearing the land with fire at the end of September (dry season) or early October (the rainy season) yearly, as it could be seen from the changes of the land cover from secondary swamp forest into swamp shrub and from secondary swamp forest into fields. Meanwhile, at the protected area where peat was dominant, land cover change occurred due to land rights conflicts, and not to the use of fire for land preparation using fire by Dayak Ngaju communities, because they found that the results were not good and the planted rice would die three months after planting..

Abstract. Permana I, Awaluddin A, Saryono. 2019. Methylene blue decolorization fungi from crude oil-contaminated soils. Biodiversitas 20: 2693-2697. One of the world problems is the treatment to remove dyes in textile wastewater. Nowadays, the most effective and compatible method to the environment is decolorization by microorganisms. Therefore, the objective of this study is to find out the best fungi to decolorize synthetic dye methylene blue (MB). Total eight fungi that isolated from crude oil-contaminated soil were analyzed to study the effect of various parameters such as pH, the concentration of dyes, contact times and agitation on their rate of reaction. The initial screening showed that Penicillium sp. FTM7 had greater potential in biodegradation the MB. The optimum decolorization of MB by Penicillium sp. was found after 8 days incubation with agitation 150 rpm and concentration of MB is 40 ppm and unadjusted pH (95.45%). The decolorization of MB was found to follow first-order reactions.
