PENGARUH PENAMBANGAN PASIR LAUT TERHADAP KEKERUHAN PERAIRAN TELUK BANTEN SERANG

Pesatnya pertumbuhan ekonomi dan penduduk di daerah pesisir menjadikan kebutuhan akan ruang yang lebih luas sehingga reklamasi kawasan pesisir menjadi pilihan utama yang banyak ditempuh. Pemanfaatan pasir laut yang berlebihan dan tidak terkendali dapat merusak daya dukungnya. Penelitian ini bertujuan untuk mengkaji gangguan pada kekeruhan perairan Teluk Banten Kabupaten Serang yang disebabkan kegiatan penambangan pasir laut pada periode 2004-2015. Penelitian ini menggunakan metode analisis korelasi dan regresi polinomial orde 2. Penambangan pasir laut oleh sebuah perusahan swasta dilakukan di Teluk Banten pada perairan Desa Lontar Kecamatan Tirtayasa Kabupaten Serang dan Desa Pulo Panjang Kecamatan Pulo Ampel Kabupaten Serang. Penambangan dilakukan mulai tahun 2004 hingga 2015, dengan total produksi hingga Januari 2015 adalah 11.513.972 m3.Hasil penelitian menunjukkan hubungan yang kuat (r = 0,9835) antara penambangan pasir laut dengan peningkatan kekeruhan perairan Teluk Banten dengan persamaan regresi, y(x)= 90,8494 + 9,2392.10-3 x - 1,3059.10-7 x2.  Disarankan aktivitas penambangan pasir laut dapat dipertimbangkan untuk dihentikan sementara karena telah meningkatkan TSS perairan Teluk Banten hingga melampaui ambang batas baku mutu lingkungan

PRELIMINARY STUDY ON THE DISTRIBUTION OF THE AEROBIC HETEROTROPHIC BACTERIA AND THE MICROBIAL INDICATORS IN JAKARTA BAY

The distribution of heterotrophic bacteria and microbial indicators in the Jakarta Bay were studied. Higher frequency of occurrences of the total coliform were observed in water samples collected near rivermouths or in the vicinity of islands. Lower frequency of occurrences of total coliform were obtained from samples collected from the far northern side of the Bay. The isolated strains belong to the genera Achromobacter, Vibrio, Flavobacteria, Micrococcus and coliforms. Micrococcus and coliforms were mostly obtained from samples collected at stations which are suspected to be highly influenced by human activities. The presence of Vibrio parahaemolyticus-like organisms were also determined. Occurrences of the genera varied unpredictably but were mostly within the six genera mentioned

WATER QUALITY INDICATOR BACTERIA IN BENGAWAN SOLO AND PORONG RIVERS AND THEIR ESTUARIES

Water samples taken from rivers and estuaries stations in Bengawan Solo and Porong rivers in East Java were analyzed for the pollution of indicator bacteria in July-August and NovemberDecember 1984, to determine the influences of domestic wastes on the quality of these waters. Higher frequency of occurrences of high total coliform, fecal coli and fecal streptococci were observed in water samples collected in river stations, river mouths and in the vicinity of dense populated areas. The distribution of saprophytes, freshwater bacteria and indicator bacteria were also studied. The changes in the bacterial population as funciton of the salinity were shown during the observations. Some pathogenic bacteria like Salmonella, Yarsinia, and Vibrio parahaemolyticus and others have been isolated from waste and mud samples
