Abstract

The aims of this research were to know the water environmental quality and to determine the diversity and abundance of plankton in Youtefa and Yos Sudarso Bay. The Sampling was conducted from October 2012 to January 2013 at two observation stations of Youtefa Bay and four observation stations of Yos Sudarso Bay during the dry and rainy seasons. The Sampling of plankton in each observation stations were made horizontally using a plankton net size number of 25. Biological data are determined using diversity index, uniformity index, dominance index and abundance calculations. Physico-chemical parameters were analyzed descriptively by comparing the result data of research with waters quality standards for marine’s biota based on decree of Environment Minister No. 51 year 2004. The results of water quality showed that in general, the quality of aquatic environment in Youtefa and Yos Sudarso Bay did not comply with water quality standards for marine’s biota issued by The Minister of Environment of Republic of Indonesia. While based on the diversity index analysis, water quality in Youtefa and Yos Sudarso Bay was categorized as a half polluted-heavily polluted. Diversity of plankton in Youtefa and Yos Sudarso Bay during the dry and rainy seasons was categorized as low-medium. Abundance of plankton in Youtefa and Yos Sudarso Bay was in low category. Key words: Abundance, diversity, plankton, Youtefa Bay, Yos Sudarso Bay.

Abstract

The research of toxicity local isolate Bacillus thurigiensis (H-14) and 18 codeword isolate along the efectivity on the water concerning to the Culex and Anopheles. The research aim to acquainted about the toxicity of B. thuringiensis isolate H-14 local and 18 codeword isolate along of the toxicity on the water concerning to the Culex and Anopheles. The methode is laboratory experiment wich used complete randome, analysis the data to wich BNJ test and 0.05% confidence standart. The result shows  that isolate of local B. huringiensis H-14 and coderword 18 toxic concerning to Culex and Anopheles B.thurngiensis H-14   0.06 ml concentrate, 0.08 ml  concentrate and 0.1 of effective of the Anopheles death until 6 day, and 0.1 ml effective concentrate show the Culex death until 7 day.Isolate 18 in 0.08 concentrate and 0.1 effective of  Culex  until 5 day and 0.1 ml concentrate 0.1 ml effective of the Anopheles until 7 day. Analysis varians shows the different act control concentrate  in the other side, the act of concentrate isnt different significant. Key words: Bacillus thuringiensis, Local isolate, toxicity, Anopheles and Culex larva.

Abstract

Sea cucumber is one of high value economic commodity due to not only having a fairly completed nutrition, but also used as the raw material for production of drugs, cosmetics and others. Therefore it becomes one of the highly potential export commodities. However, the target of catching sea cucumbers community intensively will give a negative impact on its sustainability. Sea cucumber has long been recognized and protected by the people in Padaido islands known as sasisen or sasi system. Although it has been conserved through sasisen system, but tends decline recently. This happen due to the high fishing activities by fisherman. Sea farming methods is a sea fisheries development concept in shallow waters such as the merger between aquaculture and capture fisheries by utilizing leading commodity in potential cultivation area. Sea farming is a system of utilization of marine ecosystem-based marine culture with the ultimate goal to improve the stock of fish (fish resources enhancement) to the sustainability of fisheries and other marine-based activities such as ecotourism. This paper will discuss the development opportunities of sea farming system that is integrated with the prevailing of local wisdom in Padaido Islands, Biak Numfor Regency, Papua, namely sasisen. This system works in conserving sea cucumber resources and increasing incomes of local communities in Padaido island through the creation of alternative livelihoods specifically in sea cucumber cultivation. Therefore, these models and approaches can be considered to manage coastal and marine resources in a sustainable way in Padaido Islands, Biak Numfor Regency.Key words: Sea cucumber, sustainable management, sasisen, Padaido Islands.

Abstract

The research of toxicity local isolate Bacillus thurigiensis (H-14) and 18 codeword isolate along the efectivity on the water concerning to the Anopheles.  The research aim to acquainted about the toxicity of B. thuringiensis isolate H-14 local and 18 codeword isolate along of the toxicity on the water concerning to the Anopheles. The methode is laboratory experiment wich used complete randome, analysis the data to wich BNJ test and α..05. The result shows  that isolate of local B. huringiensis H-14 Anopheles farauti Laveran  B.thurngiensis H-14   0.06 ml concentrate, 0.08 ml  concentrate and 0.1 of effective of the A.farauti death until 6 day, and concentrate 0.1 ml effective  show the Anopheles  death until 7 day. Analysis varians shows the different act control concentrate  in the other side, the act of concentrate isnt different significant.   Key words: Toxic, Bacillus thuringiensis, Anopheles farauti Laveran.
