Abstract


Estuary Way Belau is a residential area with high population. Utilization of Way Belau River diverse enough so that water river estuary Way Belau has decreased the quality of the water environment as reflected in the black color tends to muddy the water and the high sedimentation rate. The purpose of this research was to determine the water quality (water and sediment) in terms of physical and chemical parameters Estuary Way Belau Bandar Lampung. The research in the Estuary Way Belau of Bandar Lampung had been held in June 2010 to August 2010. The results showed that the measurement of physical and chemical conditions generally still in quality standard (Kepmen No. 51/MENLH/2004) and marine water quality management and pollution control (PP No. 82 Tahun 2001). Characteristics of the fraction of sediment in the estuary Way Belau fraction is dominated by sand with organic matter content of the total average in research stations ranged from 0.68 to 5.41%, the average nitrate content ranged from 2.4 to 14.4 ppm and the sediment pH ranged from 6.58 to 7.47.

 

Key words : estuary Way Belau,  sediment, water quality

 

ABSTRAK

Muara Sungai Way Belau adalah daerah pemukiman dengan jumlah penduduk yang tinggi. Pemanfaatan sungai Way Belau cukup beragam sehingga perairan muara Sungai Way Belau mengalami penurunan kualitas lingkungan perairan yang tergambar dari warna perairan keruh cenderung hitam serta tingkat sedimentasi yang tinggi. Tujuan penelitian ini adalah mengetahui kualitas perairan (air dan sedimen) ditinjau dari parameter fisika dan kimia muara Sungai Way Belau Bandar Lampung. Penelitian dilaksanakan pada bulan Juni-Agustus 2010 di perairan muara Sungai Way Belau Bandar Lampung. Hasil penelitian menunjukan Pengukuran kondisi fisika dan kimia secara umum masih memenuhi standar baku mutu untuk biota laut (Kepmen No. 51/MENLH/2004) dan standar pengelolaan kualitas air dan pengendalian pencemaran (PP No. 82 Tahun 2001). Karakteristik fraksi sedimen di muara Sungai Way Belau didominasi oleh fraksi pasir dengan kandungan bahan organik total rata-rata pada stasiun penelitian berkisar 0,68 - 5,41 %, kandungan nitrat rata-rata berkisar antara 2,4 - 14,4 ppm dan pH sedimen berkisar antara 6,58 - 7,47.

 

Kata Kunci : kualitas air, muara sungai Way Belau, sedimen
