Maluku is one of the archipelago province in Indonesia that has small pelagic fish resources with widespread distribution, such as lompa (Thryssa baelama Forsskål). One of lompa habitat in Mollucas is in Apui coastal areas. The presence of lompa depends on physical and chemical parameters in the waters. This study aims to determine the influence of physical and chemical parameters on the presence of lompa in Apui coastal area Central Mollucas. This study was conducted in June - July 2015. This research is ex-post facto using the value of Environmental Water Quality Index which refers to US-National Sanitation Foundation-Water Quality Index (NSF-WQI). Physical and chemical parameters measured include temperature, velocity, depth, brightness, salinity, pH and dissolved oxygen. The results of calculations with the Indeks Mutu Lingkungan Perairan (IMLP) are 95.61; 92,15; 88.61; 96,37; 93,76; 79.57. And the results of lompa fishing were 181, 162, 205, 173, 184, and 97 respectively. The research conclusion is that the Apui coastal areas are in good condition and potential as lompa habitat.

The study to calculate the water quality index was conducted in the Gulf of Tonkin at the surface water in August 2018. The calculation results showed that out of 48 surveyed points, there was 1 point in the Northeast area at poor water quality, 15 points in the Northeast and coastal areas from Thanh Hoa to Thua Thien Hue at medium water quality, 14 points in the Gulf of Tonkin, Northeast and Con Co Island at good water quality, the remaining 18 points in the Gulf of Tonkin and Bach Long Vi Island at excellent water quality. Overall, the average water quality of the whole region was good (average WQI = 79). Considering each area, the Gulf of Tonkin area had good and excellent water quality, the Northeast had water quality from poor to good level, the coastal areas from Thanh Hoa to Thua Thien Hue had medium water quality, Con Co Island area had good water quality, Bach Long Vi Island area had excellent water quality.

This study takes a look into groundwater quality at Ugbor Dumpsite area using water quality index (WQI), 2-Dimensional (2-D) geophysical resistivity tomography and vertical electric sounding (VES).The geophysical resistivity methods employed revealed the depth to aquifer, the geoelectric layers being made up of lateritic topsoil, clayed sand and sand. Along the trasverse line in the third geoelectric layer of lateral distance of 76 m to 100 m is a very low resistivity of 0.9 to 13 m from a depth range o f about 3 to 25 m beneath the surface- indicating contamination. Water samples were collected and analyzed at the same site during the raining season and during the dry season. The value of water quality index during the raining season was 115.92 and during the dry season was 147.43. Since values at both seasons were more than 100, it implies that the water is contaminated to some extent and therefore poor for drinking purpose. The Water Quality Index was established from important analyses of biological and physico-chemical parameters with significant health importance. These values computed for dumpsite area at Ugbor were mostly contributed by the seasonal variations in the concentrations of some parameters, such as, conductivity, total dissolved solids, hardness, alkalinity, chlorides, nitrates, calcium,  phosphates, zinc, which showed significant differences (P<0.01 and P<0.05) in seasonal variation.

erkembangan Kota Bogor tidak bisa dilepaskan dari keberadaan dua sungai utama yang melewatinya, yaitu Sungai Ciliwung dan Sungai Cisadane. Aktivitas penduduk di sekitar Daerah Aliran Sungai (DAS) Sungai Ciliwung dan Sungai Cisadane sangat berpengaruh terhadap kualitas air sungai, karena sebagian dari limbah buangan hasil aktivitas tersebut langsung dibuang disungai. Analisa ini bertujuan untuk mengetahui kualitas air Sungai Ciliwung dan Sungai Cisadane Kota Bogor pada tahun 2017. Data yang digunakan dari pengambilan sampel air di lapangan pada bulan Agustus di 10 titik pengamatan. Selanjutnya hasil dianalisa menggunakan Metode Water Quality Index (WQI). Parameter yang digunakan meliputi Temperatur, Total Dissolve Solid, Turbiditas, pH, DO, Nitrit, Amonia, Fosfat, Minyak dan Lemak serta Total Coliform. Parameter tersebut dianalisa secara insitu menggunakan alat portable Water Quality Checker juga melalui analisis laboratorium. dan hasilnya bahwa kualitas air yang masuk ke Kota Bogor mengalami penurunan setelah melewati area Kota Bogor.
