Abstract

Kejawanan tourist beach is one beach which is located in West Java. This beach is located side to the Kejawanan fishing port. Kejawanan beach topography sloping beach with quiet waters and the waves are not too big. The dominant wind direction throughout the year that influencet the formation of ocean waves are heading toward the bay coast of Cirebon. The existence tourist beach that is located near to the fishing port crowded with activity interesting to known the conditions coast as marine tourism area based on Water quality standars according to Decree of The Minister of Environment Number 51 of 2004. Pollution indeks is based on Decree of The Minister of Environment Number 115 of 2003. Indication of biological contamination by Diversity index of makrobentic animal. The results of the research obtained Water quality standard for marine tourism area mostly exceeded. Pollution index is at the level Heavy pollution. Diversity index of macrobentic animal are at the level of Medium Pollution. Keywords : Kejawanan, standard quality, pollution index, diversity index

Abstract

Pelabuhan Perikanan Nusantara Kejawanan secara administratif terletak di wilayah Kota Cirebon. Pelabuhan ini merupakan salah satu Unit Pelaksana Teknis dari Direktorat Jenderal Perikanan Tangkap, Kementerian Kelautan dan Perikanan yang sangat penting peranannya dalam mendukung program industrialisasi perikanan di Cirebon. Aktivitas pelabuhan perikanan yang cukup ramai dengan berbagai kegiatannya antara lain aktivitas bongkar ikan, perbengkelan serta posisinya yang dekat dengan sungai dan terdapat berbagai pabrik pengolahan ikan tentunya akan menimbulkan dampak terhadap kualitas airnya. Penelitian ini bertujuan untuk mengetahui kesesuaian baku mutu air laut untuk pelabuhan serta untuk mengetahui indeks pencemaran yang terjadi. Metode yang digunakan dalam penelitian ini pada dasarnya secara kuantitatif dimana pengumpulan data yang dilakukan dengan pengukuran kualitas air menggunakan Water quality cheker, identifikasi laboratorium untuk sedimen dan air. Hasil yang diperoleh pada penelitian ini ternyata kondisi kolam Pelabuhan Perikanan Nusantara Kejawanan dalam kondisi tercemar sedang, dimana parameter pH dan Seng berada diatas ambang batas baku mutu yang disyaratkan.

Abstract

ABSTRACTSeagrass ecosystem has a function of spawning, nursery, and feeding ground. Besides, it could be used as a bio-indicator of environmental health. This study of seagrass ecosystem was done in 17- 22 May 2014 in Lembeh Island and Tanjung Merah, Bitung. The purpose of the study is to obtain existing condition of seagrass ecosystem and its role as environment bio-indicator. Purposive sampling method was used representing all study sites. Structure analysis of seagrass communities describes the existing condition, while scoring / weighting method estimate current condition of the seagrass. Results that show there are seven species of seagrass. In the stations opposite to Bitung mainland, 75% of the seagrass are Enhalus acoroides (10-50% covers). Importance value index of the seagrass species were Enhalus acoroides (231–300 %), Thalassia hemprichii ( 102–198 %) and Halophila ovalis (110 %) respectively. Based on the weighting method and environmental standard quality, seagrass ecosystem in Lembeh island opposite to Bitung mainland was in damage and unhealthy condition, while seagrass ecosystem opposite to the open sea was in a good and healthy condition. This was due to the domestic waste that is trapped in seagrass ecosystem in the study site. It is necessary to improve awareness to maintain quality of environmental.  Keywords: seagrass, existing, bioindicator, Lembeh Island

Abstract

Small islands are particularly rich with coral reefs and seagrass ecosystems and coastal plants. Seagrass is one of the coastal ecosystems of blue carbon, which is capable of storing utilize and store CO2 in the form of organic carbon in biomass and sediment. The purpose of this study to get the carbon stock of seagrass and its role in climate change. The survey method with sampling purposive sampling representing all research sites and analyzed the amount of carbon contained in biomass and sediment. The result showed that there were eight species of seagrass found, and the highest carbon stock  on the type Enhalus acoroides at  Kapoposang island was 1.64 MgC / ha. The average value of the total biomass of carbon stock in the islands largest seagrass Bauluang island  was 1.89 ± 0.92 Mg C / ha with the largest at the ground below 77% of total carbon biomass. Carbon stock in sediments of seagrass ecosystems average of 531.87 ± 74.08 Mg C / ha up to a depth of 50 cm. The role of seagrass in Spermonde archipelago waters in climate change in both the biomass and sediment for MgC 533.25 MgC/ ha is equivalent to the use of CO2 for 1955.26 MgCO2e / ha.

Abstract

Hujan merupakan salah satu sumberdaya air yang penting bagi kehidupan manusia. Keseimbangan lingkungan dapat diketahui dari ketersediaan sumber air yang berguna untuk memenuhi kebutuhan masyarakat. Daya dukung lingkungan adalah kemampuan lingkungan untuk menunjang kehidupan manusia dan makhluk hidup lainnya. Salah satu cara menentukan daya dukung lingkungan adalah dengan pendekatan ketersediaan dan kebutuhan air. Tujuan dari penelitian ini adalah melakukan simulasi terhadap status daya dukung lingkungan berdasarkan ketersediaan air bulanan dari curah hujan dan kebutuhan air di Pulau Gili Ketapang-Probolinggo dalam satu tahun. Metode yang digunakan untuk mengetahui daya dukung lingkungan adalah analisis kuantitatif melalui perbandingan antara penghitungan ketersediaan air dan kebutuhan air. Hasil penghitungan status daya dukung lingkungan berdasarkan ketersediaan air dan kebutuhan air di Gili Ketapang apabila dihitung berdasarkan kebutuhan layak air minum 130 liter/orang/hari adalah defisit sebesar 33.389.799,47 liter/bulan.
