Abstract

Freshwater community in Lake Sentani comprise of 35 species including three endemic species, seven native species, eight anadromous fish and 17 introduced species. Two native species are Sentani Gudgeon (Oxyeleotris heterodon) and Snakehead Gudgeon (Giuris margaritacea). The survey aims to document the ecology and fish abundance of the gudgeons in Lake Sentani. Fish sampling was done passively by using gill nets with three different mesh sizes in five locations; Puai, Enandowai, Waena, Ayapo and Yahim. Substrate type, water vegetations, habitat depth and fish abundance were recorded each locations. Substrate preferences of the gudgeons are sand, mud and gravel, while O. heterodon was more abundance in sand mud substrate type. Moreover, water vegetation preference was different between O. heterodon and G. margaritacea. Sentani Gudgeon prefer habitat with dense water vegetations, while G. margaritaceus could be found in habitat with or without water vegetation. Theses two gudgeons were found in relatively the same habitat depth, up to 7 meters depth. O. heterodon and G. margaritacea had a very low abundance in the lake. It is important to conserve lake area from the edge  up to 7 meter depth that consist of sand, mud and gravel substrate types and dense water vegetation to ensure the population of these two gudgeons are abundance in Lake Sentani.   Key words: Ecology, Lake Sentani, relative abundance, O. heterodon, G. margaritacea.

Abstract

Sea cucumbers are organisms which have very important role in aquatic ecosystems as benthic biotas. The purpose of this study is to understand the public's knowledge about the diversity of sea cucumbers and its utilization in Tablasupa village. This study was conducted in May 2016, using a survey method by means of sampling and interviews. The results showed that based on the knowledge of local people, there are six species of sea cucumber. On the other hand, based on morphological identification, there were found eight species, which are Genus Actinopyga (2 types), Bohadschia (2 types), and Holothuria (6 types). Many people take advantage of the type of sea cucumbers for sale, and only a small portion is consumed. As a consequence of community activities is that increase the potential of reducing the species biodiversity of sea cucumber in the region. However, the existence of local knowledge management in this region is expected to reduce the loss of diversity and may improve the local environment ecosystem.Key words: benthic, ecosystems, Jayapura, Tablasupa, sea cucumbers

Abstract

The Bohadschia argus Jeager contains bioactive compounds that have the potential as antibiotics, antibacterial, antitumor, anticoagulants and anesthetics and alleviate cancer. This study aims to determine the content of chemical compounds group and to test the cytotoxic activity of ethanol extract of Bohadschia argus Jeager. The method for determining the group of chemical compounds was used the color reaction and precipitation using chemical reagents. The method for testing cytotoxic activity using the Brine Shimp Lethality Test (BSLT), this method commonly was used to test the safety of the use of natural ingredients as traditional medicine. The results of screening of the chemical compound group of  Bohadschia argus Jeager extract showed that the extract contained a lot of alkaloids secondary metabolites and few saponins. The results of testing of cytotoxic activity showed LC50 value of 878.22 ppm. Base on the results of this study it can be concluded that the ethanol extract of Bohadschia argus Jeager has significant cytotoxic activity against Artemia salina Leach, so it can be considered as a chemotherapeutic agent.   Key words: Screening, chemical compounds, ethanol extract, B. argus, BSLT.

Abstract

Papua has a potensial marine resources both in ecology aspect as well as in economic. To keep the richness of marine resources, conservation is needed. Tiyaitiki is a traditional conservation based on indigenous knowledge of local people of Teluk Tanah Merah Depapre Jayapura. They used their custom to conserve both the water areas and the natural resources as well. The aims of the study were to observe the diversity of plankton and fishes in Teluk Tanah Merah, and to know the quality of water based on that diversity. Research was conducted from July to August 2007.  Line transect method was used in this study. Datawere collected from three station,  at morning, noon, dawn and night separately.The result of the study were 38 genera of plankton, 21 genera of fithoplankton and 17 genera of zooplankton. Moreover, the result of fish diversity survey was 62 species. Those indicated that the water areas in Teluk Tanah Merah Depapre was in a good qualityfor fish life. Key words:  plankton, fish, Tiyaitiki, Jayapura, Papua

Abstract

Papua has a huge diversity of natural resources which can be categorized as well managed compare to other areas in Indonesia. The city of Jayapura and its surrounding are arranged to become an urban area nowadays. As an impact, many sector has changing including its land use. This research aims to understanding the knowledge, perception, and assesment of people regarding the environment particularly in Jayapura and its environs. The research was conducted in Jayapura City, Jayapura Regency and Keerom Regency with sampling method using survey, questionnaire and documentation. This research revealed that 53.0–90.0% of respondent knowing about environmental management and most of them (90.0%) gained those information from educational institution such as schools.
