Abstract

The Krakatau Islands in the Sunda Strait have been significantly impacted by catastrophic volcanic eruptions in 1883 and 2018. The marine habitats are not well studied, neither in the past nor in the present. This research is a report on the distribution and ecology of corals and sponges in the Krakatau Volcanic Complex at the three islands of Anak Krakatau, Rakata, and Panjang. This study used 100 m transects long in 5–7 m depth. Hard coral and soft coral communities are found to live with a coverage varied between 25-53% and 0-24%. Dead coral skeletons covered 14–40% of the surveyed area and did not seem to affect the abundance of sponges recorded. The Sponges occupied 0–6% of the area, and they often acted as coral competitors, shaping the benthic ecosystems. The recorded sponges only belong to the Demospongiae class, which are the Suberitid species that are commonly found in Indonesian waters, e.g., Amorphinopsis excavans, Protosuberites collaris, and Terpios sp. The excavating sponge Cliona cf. orientalis was frequently found to be a successful competitor of massive Porites sp., aggressively overgrowing live parts of the coral. Two Haliclona species and Mycale relicta colonized dead coral skeleton. Overall, the benthic communities appear healthy and are comparable to other similar locations that are not affected by volcanic activity.

Abstract

The research objective is to classify the variety of vegetation types at Mount Endut, Gunung Halimun-Salak National Park. Vegetation sampling was carried out with systematic sampling with random start. Vegetation type at alliance level was determined with vegetation ordination using factor analysis. Four vegetation alliances can be extracted from the ordination. These alliances are Castanopsis acuminatissima-Schima wallichii/Freycinetia javanica (alliance 1); Castanopsis argentea-Dendrocnide stimulans/Schismatoglottis calyptrata (alliance 2); Coffea canephora var. robusta-Quercus lineata/F. javanica( alliance 3) and Paraserianthes falcataria-Coffea canephora var. robusta/Oplismenus compositus (alliance 4). Vegetation alliances form due to their similarity in structure, composition, and physiognomy of vegetation. There are four vegetation associations at alliance 1, i.e. Castanopsis acuminatissima vegetation association, Schima wallichii vegetation association, Garcinia rostrata vegetation association, and Quercus lineata- Eurya acuminata /Freycinetia javanica vegetation association. Alliance 2 has four vegetation associations i.e.Dendrocnide stimulans vegetation association, Coffea canephora var. robusta vegetation association, Castanopsis argentea -Castanopsis acuminatissima vegetation association, and Schismatoglottis calyptrata-Etlingera coccinea vegetation association.There are seven vegetation associations belonging to alliance 3 i.e. Castanopsis acuminatissima vegetation association, Coffea canephora var. robusta vegetation association, Quercus lineata vegetation association, Garcinia rostrata-Schima wallichii vegetation association, Euodia latifolia - Pternandra azurea/Schismatoglottis calyptrata vegetation association, Raphidophora foraminifera vegetation association, and Freycinetia javanica vegetation association. Alliance 4 has five vegetation associations i.e Paraserianthes falcataria vegetation association, Coffea canephora var. robusta vegetation association, Maesopsis eminii/ Erechtites valerianifolia - Clidemia hirta vegetation association, Oplismenus compositus vegetation association, and Clibadium surinamense vegetation association.

Abstract

Waduk Selorejo yang terletak pada lintang 7° 53' LS dan 112° 21' BT dan luasnya 400 hektar, telah selesai dibangun pada tahun 1970.Waduk ini terbentuk karena terbendungnya aliran Kali Konto dan Sungai Kwayangan. Pada tahun 1973 waduk Selorejo secara tidak disengaja telah dimasuki ikan mujair (Sarotherodon mossambicus (Peters). Dominansi ikan mujair yang tertangkap, oleh Suwignyo (1973) dikatakan sebagai pencerminan meningkatnya populasi ikan tersebut.Fihak pengelola Waduk Selorejo telah melakukan penangkapan ikan dengan jaring insang secara berkala pada setiap malam minggu atau malam hari libur.Jenis usaha perikanan yang diusahakan penduduk adalah perikanan pancing.Terdapat juga penggunaan jala dan jaring tetapi jumlahnya tidak banyak karena kegiatan ini dilarang dilakukan di Waduk Selorejo.

Abstract

This study was conducted to know of potential of natural resources of Mt.Halimun used by surrounding communities and the development of bufferzone.The potential of natural resources are composed of wildlife, plant biodiversity,land and hydrology.Then, The utilization of natural resources will be correlated with the condition of socio economic and culture of communities.According to the study, it is known that the major occupation of the village communities are as farmers, who have private land or as laborers (>50%). As laborers, they worked for landlord with salary Rp. 5,000 to Rp 10,000 per day for six days per week. This condition made village communities to depend their livelihood to potential of natural resources of Mt. Halimun NP. Based on dynamic hypothesis,the bufferzone could be developed through data and information of the natural resources that utilized or disturbed by communities. The plant biodiversity are used as energy, traditional medicines, food, handicrafts and forages.Illegal hunting done by surrounding communities was hunting wild pigs, birds and monkeys.To limit the exploitation, illegal cutting, illegal hunting and deforestation The Mt Halimun NP have program social forestry and agroforestry to decrease dependency of communities to the forest. For example the sheep breeding with forage plants in bufferzone.Other programs such as goats breeding and fish or plants development could be done in border land of national park or private land of communities.

Abstract

Forage is a feed source for ruminant livestock, but one of the limiting factors of forage is high content of fiber in old forage plants. The fiber content in forage can only be degraded by rumen microbes. One of the rumen microbes that has fiber degrading activity is rumen anaerobic fungi because it can produce very active enzymes to degrade lignocellulose. The rumen anaerobic fungi are divided into several genera which are grouped base on the number of flagella in zoospores, thallus morphology and rhizoid type. The presence of fungi in the rumen is very important because fungi can form rhizoid which will penetrate the feed particles and degrade plant cell walls physically and chemically. In addition, fungi can produce fiber degrading enzymes such as cellulase, hemicellulase, pectinase, and lignocellulase which can increase feed digestibility. However, in Indonesia there is not much study of the potential for rumen anaerobic fungi, so the aims of this review paper is to discuss the potential of anaerobic fungi rumen in improving fiber digestibility in livestock.

Abstract

Indonesia is an archipelago that has complex biodiversity and distribution of fauna, including mosquitoes. Indonesia currently has around 456 species of mosquitoes and is the second-largest in the world. Update on the information about the species list and distribution of mosquitoes in Indonesia compiled by O'Connor and Sopa (1981) have never been conducted for nearly 40 years. The purpose of this study is to convey taxonomic updates and species distribution as well as the key to identifying mosquito in the tribe Ficalbiini in Indonesia. The Ficalbiini tribe consists of the genus Ficalbia and Mimomyia. The author has reviewed some literature about taxonomic information, species distribution, and morphological characters of tribe Ficalbiini members. The list of species and their distribution updated with literature study and mosquitoes collection from Rikhus Vektora 2015 – 2018 organized by Balitbangkes, Ministry of Health, Indonesia. The mosquitoes were identified on the spot and confirmed in the laboratory. Identification results also have undergone an appeal with external parties. Indonesia currently has 11 species in the tribe Ficalbiini, namely Ficalbia ludlowae, Fi. minima, Mimomyia elegans, Mi. luzonensis, Mi. fusca, Mi. mogii, Mi. aurea, Mi. chamberlaini, Mi. flavens, Mi. hybrida, and Mi. modesta. Mimomyia mogii and Mi. aurea are two additional species to the species list compiled by O'Connor and Sopa (1981). The species of the tribe Ficalbiini spread throughout Indonesia, except in the Maluku islands. The identification key for species in the tribe Ficalbiini in Indonesia has never been available before. Thus, species identification key for female mosquitoes in the tribe Ficalbiini included in this paper as well.

Abstract

Tor fish is a potential local fish. It has social, economic and religious value and contains albumin which is equivalent to snake head fish. As a local fish cultivation potential, an accurate description of the early development stages of this species, will have value for ichthyologists and can facilitate cultivation efforts to increase production. This study aims to understand the embryology of three tor fish species and to determine the condition of larval performance at the beginning of hatching. The division process begins when the cell nucleus is divided into 2 blastomers, then continues to reach 32 cells in the first 10 hours after fertilization. At 10–20 hours after fertilization the eggs enter the morula, blastula and gastrula phases. After 20 hours, the organogenesis stage occurs. Tor douronensis hatched the fastest, more than 100 hours after fertilization (0.70–0.80 cm length, 0.0073 g weight and 8.40±1.83% abnormality). Tor soro over 120 hours (length 0.80–0.90 cm, weight 0.0125 g and abnormality 2.47±0.12%) and Tor tambroides above 140 hours after fertilization (length 1,00–1,09 cm, weight 0,0146 g and abnormality 2.93±0.31%). It can be concluded that there is no difference in the process of embryogenesis of the three species until the gastrula stage. The difference arises in the organogenesis phase, where the Tor douronensis organ develops most rapidly, followed by Tor soro and Tor tambroides.
