Abstract

Kondisi kualitas air suatu perairan yang baik sangat penting untuk mendukung kehidupan organisme yang hidup di dalamnya. Penentuan status mutu air perlu dilakukan sebagai acuan dalam melakukan pemantauan pencemaran kualitas air. Penelitian ini bertujuan untuk mengkaji status mutu air laut berdasarkan konsentrasi parameter surfaktan dan minyak di perairan Distrik Depapre, Kabupaten Jayapura. Pengambilan sampel air laut dilakukan di lima stasiun penelitian, kemudian hasilnya dibandingkan dengan baku mutu air laut untuk biota laut berdasarkan KEPMEN-LH No. 51 Tahun 2004. Hasil penelitian menunjukkan bahwa konsentrasi surfaktan di perairan Distrik Depapre berkisar antara 0,08?0,22 mg/L, sedangkan konsentrasi kandungan minyak berkisar antara 0,14?0,41 mg/L. Berdasarkan baku mutu air laut, konsentrasi surfaktan dan minyak belum melampaui baku mutu dan masih sesuai untuk biota laut di perairan Depapre, Kabupaten Jayapura. Hasil penelitian ini memberikan informasi bahwa kondisi perairan Depapre belum tercemar oleh limbah surfaktan dan minyak. Namun tidak menutup kemungkinan bahwa konsentrasi tersebut dapat terus meningkat, sehingga perlu upaya lebih lanjut dari pemerintah dan masyarakat untuk meminimalkan jumlah limbah surfaktan dan minyak yang masuk kelingkungan perairan laut. Good water quality is critical to support the life of organisms. The determination of water quality status was needed as a reference to monitor water pollution. This study aimed to assess the condition of water quality based on the concentration of surfactant and oil parameters in the Depapre waters, Jayapura Regency. Sampling was carried out in five research stations; then the results were compared with water quality standards based on KEPMEN-LH No. 51 Tahun 2004 for marine biotas. The result showed that the concentration of surfactant in Depapre waters was 0.08?0.22 mg/L, while the oil concentration was 0.14?0.41 mg/L. Based on water quality standards, surfactant and oil concentration has not exceeded the quality standards and are suitable for marine biotas in Depapre waters, Jayapura Regency. Results showed the condition of  Depapre waters had not been polluted by surfactant and oil waste. However, it does not rule out the possibility that the concentration can increase so that it needs further efforts from the government and the community to minimize the amount of surfactant and oil waste entering the marine environment.

Abstract

The coastal areas of both Jayapura Municipality and Regency which is directly opposite to the Pacific Ocean with the multifunctional use is a vulnerable area to disasters. The coastal vulnerability is determined by considering some influential factors, that is geomorphology and elevation to minimize the coastal damage impacts. The purpose of this study is to determine the coastal vulnerability index of Jayapura City and Regency focusing on the coastal geomorphology and elevation. The study area covers a coastal area of 241.86 km along the coastlines of Jayapura Municipality and Regency. The study method includes data collection on the coastal geomorphology and elevation characteristics. The value of coastal vulnerability index of each parameter is determined by dividing into five categories of coastal vulnerability. The result shows territorial division as follows: 145.88 km (61.18%) was not vulnerable, 33.14 km (13.90%) was less vulnerable, 29.03 km (12.17%) was a moderate vulnerability, 12.12 km (5.08%) was vulnerable, and the remaining 18.29 km (7.67%) was very vulnerable. The coastal vulnerability of Jayapura City coastal areas categorized into three classes, i.e. not vulnerable, moderate vulnerable and vulnerable, while the Jayapura Regency coastal areas felt into the following classes: not vulnerable and moderate vulnerable. The most vulnerable areas were of Abepura District, South Jayapura District and Muaratami District, all in the Jayapura Municipality administration. Those areas with high elevation level were not vulnerable at all.

Abstract

Chlorophyll-a is one of the parameters determining the primary productivity of water. In the fisheries sector, information on chlorophyll-a concentration in marine waters is very important for the prediction of fishing grounds. This study aims to analyze the variability of chlorophyll-a concentrations in Cenderawasih Bay and the surrounding waters, both spatial and temporal variability. Data from the Aqua-MODIS Level 3 monthly composite period from January to December 2019 was used to determine the concentration of chlorophyll-a. Time-series data are used to determine fluctuations of chlorophyll-a concentrations, while interpolation with the kriging method is used to determine the spatial distribution of chlorophyll-a. The analysis showed that the monthly average value of chlorophyll-a concentration in the study area ranged from 0.1988 ? 0.3415 mg.m-3. The average value of chlorophyll-a concentration increases from March to June and then decreases in July or August. The highest average chlorophyll-a concentration was in March and the lowest in January. The maximum chlorophyll-a concentration in April and the minimum in August, which is around 9.1089 mg.m-3 and 0.0975 mg.m-3, respectively. The concentration of chlorophyll-a in Cenderawasih Bay and its surrounding waters is dominated by a low concentration, which ranges 0.1482 ? 0.3158 mg.m-3. Generally, the variability of chlorophyll-a concentrations in the study area is influenced by seasons. The average chlorophyll-a concentration is high in the Transition I (West-east) and East seasons and will decrease in Transition II (East-West) until the West season. Spatially, chlorophyll-a concentrations in coastal areas are higher than in offshore waters. High chlorophyll-a concentrations are found around the border between Nabire Regency and Waropen Regency. The amount of run-off flow that supplies nutrients from the mainland greatly affects the high concentration of chlorophyll-a in the coastal area.
