Abstract

Bukit Tiga Puluh National park (TNBT) of Riau Province is a nature conservation area with a high diversity of fauna, one of which is the butterfly. Butterfly species diversity is influenced by the vegetation in their habitat. The TNBT utilization zone has a habitat type with varied vegetation. There is no information about the species of butterflies in the area. This study aimed to identify morphological character of butterflies and vegetation based on morphological characters. The method used was exploration. The catching area of the butterfly was the Granite waterfall and the Bukit Lancang path of TNBT utilization zone. Samples made as insectarium and herbarium. The  identification of butterfly characters consisted of the head, thorax, abdomen, legs and wings. There were a number of different types of butterflies and plants between the Granite waterfall area (22 and 28 species) and the Bukit Lancang paths (5 and 9 species). The type of butterfly was dominated by the family Nymphalidae. This is due to the amount of vegetation and environmental conditions that are more favorable in the granite waterfall area. The key determinants of butterfly species are the characters of the wing. The results of this study can contribute to maintaining the TNBT butterflies in Riau Province and also as database information of butterflies species in Indonesia.

Abstract

Marine ornamental trade has been developing for several years with Indonesia as one of the major exporter countries. Among the popular marine ornamental fish in the local and international markets belong to the family of Chaetodontidae. The existence of this family has been reported from several areas in Indonesia. However, no information is available in terms of their phylogenetic relationships of the fish from the south coast of West Java. The aim of this research was to asses the phylogenetic relationships among ornamental fish members of Chaetodontidae in the South Coast of West Java. Fish samples were collected from two trading sites Ujung Genteng and Taman Manalusu. Collected fish were identified using a previously published study. The evolutionary relationships among species were analyzed statistically through phylogenetic analysis based on maximum parsimony algorithm and Kimura 2- Parameter substitution model as implemented in PAUP 4.0 software. Tree branching pattern supported by 1000 bootstraps pseudo-replicates and out-group comparison. Daschyllus trimaculatus used as outgroup species. Based on the study, Chaetodontidae from the South Coast of West Java formed one monophyletic group compared to Dascylus trimaculatus with Chelmon rostratus was the basal species. All the remaining species were the derived species. There are CI and RI value gained. The consistency index (CI) value of this family is 0.5833, and the retention index (RI) is 0.5082.

Abstract

 Environmental characteristics can influence the distribu-tion of animal communities including fish in aquatic habitats such as a river. The study of fish communities in Cisadea River aimed to learn the relation between the fish community structure and the environmental characteristics of the river itself. This research was conducted in Cisadea River, Cianjur Regency, West Java, Indone-sia during dry season from July 2012 until February 2013. Samples of fish were caught using active fishing gear (Electrofishing Gear, spreading nets, scoop, lift net) and passive fishing gear (trap). The results showed that the quality of the physical chemistry of Cisadea waters was still in the normal range that could support fish life. The fish community in Cisadea River consisted of 11 orders, 26 families, 35 genera and 48 species. During the study, Rhyacichthys aspro (19,85%) and Glyptothorax plathypogon (20,15%) were the domi-nant species caught. The diversity index value (H’) was 2.87 (mid-dle category) with the dominance value of 0.09 (low category) and evenness value of 0.74 (high category). Moreover, community simi-larities according to the presence of species made the LC1 and LC2 locations in one group while the LC3 locations in a separate group.

Abstract

A bamboo inventory for Banggai Kepulauan has never been done. Knowledge of the islands’ floristic diversity is poor. This study explored bamboo diversity in Banggai Kepulauan, Central Sulawesi, Indonesia. We conducted fieldwork from June – July 2019 on the islands of Peleng and Bakalan. Bamboo specimens were collected and deposited in Herbarium Bogoriense. We describe these specimens here. We found eight species: Bambusa tuldoides Munro, B. vulgaris Schrad. ex Wendl., Dendrocalamus asper (Schult.f.) Backer ex Heyne, Gigantochloa atter (Hassk.) Kurz, Neololeba atra (Lindl.) Widjaja, Schizostachyum brachycladum (Kurz ex Munro) Kurz, S. lima (Blanco) Merr., and Thyrsostachys siamensis Gamble. Here we record information on morphology, habitat and distribution alongside photographs and an identification key to the bamboo species of Banggai Kepulauan.

Abstract

   Some small islands in Balikpapan Bay consist of dry land which may have different vegetation structure and composition. Our study was the first to uncover vegetation conditions and soil proper-ties of dry land on small islands in Balikpapan Bay, which has never been conducted before. The research was carried out on Kalawasan and Karantina islands. Information on vegetation was obtained by applying a line transect method. Data on soil properties were col-lected by setting up 3 sampling plots in each transect of vegetation. Parameters used for analysing vegetation including relative densi-ty, relative frequency, relative dominance, Shannon-Wiener diversi-ty index, evenness index, and similarity index. Meanwhile, data on soils were analysed descriptively. Trees on Kalawasan island were comprised of 241 individuals belonging to 21 species. There were 61 individuals (22 species) of trees on Karantina island. The diver-sity index of trees on Kalawasan and Karantina island was 2.55 and 2.72, respectively. The tree evenness index was 0.84 on Kalawasan island and 0.88 on Karantina island. The index of similarity for trees between the two islands was 0.21. Furthermore, the soil character-istics on Kalawasan and Karantina islands showed similarities. In general, soil in Kalawasan and Karantina islands could be catego-rised as marginal soil which was common in East Kalimantan. Con-sidering the rapid loss of tropical forests in the mainland of Kali-mantan indicates that the small islands of Balikpapan Bay play an important role in future biodiversity conservation in East Kalimantan.

Abstract

Barred loach is wild fish in which there is no information related to its enzymatic digestive capacity yet. Therefore research on this subject needs to be conducted.  The spectrophotometry method was used to study protease, lipase, and amylase activities in barred loach. The study used 89 fish with an average weight of 3.61 ± 0.26g, and 1.68 ± 0.21g.  The results showed that pH 7.0 was the highest protease activity. Similarly, lipase activity found  between pH 7.0 and pH 8.1. Still, the amylase activity found to be high at pH 8.1. Protease activity also found to be high in the posterior intestine than in the hepato-pancreas and anterior intestine. Lipase and amylase activities did not found differences between hepato-pancreas, anterior intestine, and posterior intestine. In conclusion, the protease, lipase, and amylase activities of barred loach found along the gastrointestinal tract in both large and small fish, which shows that barred loach can digest protein, fat, and carbohydrates in diets better.

Abstract

Peanut has high economic value and a significant role in food needs. the national food supply needs for peanuts to date have not been sufficient. This study aimed to determine the effect of organic waste which in this case is mushroom baglog compost and sheep manure on the flowers and pods of peanuts. The study was conducted on March-July 2018 in Subang district using the simple experimental plot method and group-randomized factorial design with two factors with each treatment done triplicate. The first factor is the baglog compost (soil without baglog compost, 90 g/plants, 120 gr/plants); the second factor is sheep manure dose (without sheep fertilizer, 90 gr/ plants, 120 gr/plants). The results showed that the application of baglog compost and sheep manure fertilizer at concentrations of 90 g and 120 g, respectively increased the number of flowers and potential pods. Moreover, Sheep manure fertilizer at a concentration of  120 g/plant, increased the dry weight of pods, seed, and 100 seeds even though was not significant.

Abstract

Its crucial to get information about lead (Pb) heavy metal pollution from mining and oil palm plantation on species density in mangrove ecosystem, to anticipate its impacts. This study aimed is to compare the types and densities of vegetation in mangrove ecosystems allegedly due to mining in Setarap village, Tanah Bumbu Regency and oil palm plantations in Kuala Tambangan Village, Tanah Laut Regency. We also analysis the condition of waters (TDS, pH and DO) and organic content in sediments to acquire data from the South Kalimantan mangrove ecosystems. The results showed there were four species of true mangroves (Avicennia alba, Acanthus ebracteatus, Nypa fruticans and Rhizophora apiculate) could live well in the environment affected by mining or oil palm plantations. The species density for trees was low (933 ind/ha) for mangroves affected by coal mines, while those affected by oil palm plantations had higher densities (1,067 ind/ha). pH value of waters in affected area by coal mining showed more acidic value (pH 5.76) especially at the back, while those by palm oil plantations are more acidic (pH 6) in the estuary. Organic matter content in sediments affected by coal mines was in the range of 0.61-6.59%, while those affected by oil palm plantations showed higher values (0.12-2.19%). Lead heavy metal content (Pb) in waters affected by coal mines was 0.031-0.056 mg/L, while the area affected by oil palm plantations was of higher value (0.110-0.128 mg/L). Lead (Pb) levels in sediments indicate higher values than waters, which reach 3.512-6.046 mg/Kg (affected by coal mines), and in areas affected by oil palm plantations reaching 6.658-6.66 mg/Kg. The general conclusion is that vegetation densities in areas affected by coal mines are lower than oil palm plantations. The level of lead  (Pb) pollution in the sediments is higher than in the waters.

Abstract

According to the Flora of Java, there is only one species of Evolvulus in Java, namely Evolvulus alsinoides. Since then, a second species was reported in 2017 from Universitas Indonesia, Depok, West Java, as an alien naturalized species. Some recent field studies have been conducted to provide updated taxonomic information of the genus on this island. The field observations were carried out in Banten, Jakarta, West Java, Jogjakarta, and East Java from March to December 2019. The herbarium studies were also conducted in Herbarium Bogoriense, Herbarium of Bogor Botanic Gardens, Herbarium Bandungense, and Herbarium of the Department of Biology, Universitas Indonesia. Our study reveals one newly recorded species of Evolvulus in Java already grown in cultivation, namely E. glomeratus Nees & Mart. subsp. grandiflorus (Parodi) Ooststr. Besides that, Evolvulus nummularius is now also reported to occur in other sites of West Java and extended to Central Java. An updated key to Evolvulus in Java, descriptions to both species, photographs, and brief discussions are provided.
