Abstract

Water quality monitoring is one of important activity, especially in coastal water, which susceptive with pollution. Water area of Serangan Island is a tidal flat area, influenced by fresh water and sea water inputs. The existence activities, such as cage aquaculture and tourism, and input from river, are threatened to decrease the water quality in north of Serangan water. This research was conducted to the condition of water quality based on water quality standard for aquatic organisms and its spatial distribution. The parameters measured were temperature, salinity, pH, DO, turbidity, and BOD5, in 8 sample points. Some parameters measured directly on water surface (temperature, salinity, pH and DO) and the others were analyzed in laboratory (turbidity, and BOD5). BOD5 was analyzed by standard method of Delzer & McKenzie. Based on research, the result of temperature values ranged from 28,9°C-30,5°C; salinity 29,6 ppt-32,7 ppt; pH 7,7-7,9; DO 3 mg/L-4,4 mg/L; turbidity 1,9 ntu-7,6 ntu; and BOD5 2,8 mg/L-5,4 mg/L. The water quality in Serangan had a different spatial distribution in each parameters. Overall, based on research result, the water quality condition in the body water of Serangan island was good and suitable to support aquatic organisms living.

Abstract

Perairan teluk Saleh memiliki keanekaragaman hayati laut yang berpotensi sebagai obyek wisata bahari. Keberadaan keanekaragaman hayati laut tersebut tidak terlepas dari kondisi kualitas perairan sebagai penunjang kehidupan organisme akuatik sebagai obyek dari wisata bahari. Oleh karena itu, penelitian terhadap analisis kualitas air untuk wisata bahari di teluk Saleh diperlukan. Penelitian ini dilakukan pada 8-10 Mei 2015 di teluk Saleh, Kabupaten Sumbawa dengan mengambil sebanyak 29 lokasi stasiun pengamatan. Pengambilan data kualitas perairan dilakukan secara purposive sampling dengan menggunakan alat multiparameter WQC-24. Parameter yang diukur diantaranya adalah kecepatan arus, kecerahan, kekeruhan, suhu, pH, salinitas dan DO. Analisis data dilakukan secara deskriptif dan menggunakan analisa PCA (Principal Component Analysis). Hasil pengukuran menunjukan bahwa nilai kekeruhan (pada stasiun 25 dan 50), fosfat dan nitrat melebihi baku mutu Kepmenneg LH no 51 tahun 2004 Lampiran II dengan nilai rata-rata berturut-turut 20,5 NTU; 0,074 mg/L; dan 8,4 mg/L. Secara keseluruhan perairan teluk Saleh tergolong baik dan cocok sebagai kawasan wisata bahari. Berdasarkan analisis PCA diperoleh parameter yang berperan kuat di lokasi adalah konduktivitas, salinitas, suhu, kecepatan arus dan kekeruhan.

Abstract

Giant prawn (Macrobrachium rosenbergii) is a potential fishery commodity. Recently, the commercial aquaculture of giant prawn has developed quite rapidly, especially in the rearing sector, due to its high economic value and accessible cultivation technology application. Low survival and growth are the causes of delays in the cultivation of giant prawns. The quality of the food for giant prawns is important to support the survival of the prawns during aquaculture activities. This study looks at how adding vitamins E and K to artificial food affects the growth and survival of giant prawn larvae from the Galah Prawn Seed Center (BBUG) in Klungkung, Bali. The results show that vitamin E had the highest influence on the growth and survival of giant prawn larvae, with 35.55% survival and a 4.727 growth index. Meanwhile, vitamin K in the prawn feed has no effect due to poor water quality and high mortality. The range of measured water quality was temperature (26-31°C), pH (7.5-7.8), and salinity (5-20 ppt). In general, this study shows that vitamin E had a positive effect on the growth and survival of giant prawn larvae.
