Abstract

Water is the most important requirement for all organisms, either to humans, plants, animals, and microorganisms. It was caused water function in the growth and survival organisms. Aquaculture is an activity to maintain, raise, and/or breeding fish and harvest their products in a controlled environment. Cultivation was done in a sustainable manner for the benefit.Pollution in water can be caused death of fish is heavy metal cadmium (Cd) pollution. Processing of heavy metal contaminated water is the most simple and low cost is a biological treatment with kariba weed (Salvinia molesta). But the effect of kariba weed to the decline of heavy metal cadmium is not significantly reduced, so that needs to be combined with the zeolite so that the heavy metal cadmium decline more significantly. This reseacrh to determine the effect of the combination kariba weed (Salvinia molesta) and zeolite to the decline of the heavy metal cadmium (Cd). This reseacrh uses a completely randomized design (CRD) with four treatments performed five repetitions, treatment A using 0 g kariba weed and 150 g of zeolite, Treatment B using 50 g kariba weed and 100 g of zeolite, Treatment C using 100 g kariba weed and 50 g of zeolite and treatment D using 150 g kariba weed and 0 g zeolite. The result on this research analize by  ANOVA statistical test (Analisis  of  Variance) to know there was the different between treatments, afterwards, continued by space doubled test Duncan. The result showed combination kariba weed (Salvinia molesta) and zeolite significant effect on decreasing the concentration of heavy metal cadmium (Cd) (F count > F Tabel 0.05). It is evident in this research, and only had one week treated water cadmium (Cd) of 1 ppm concentrations is fall. The averages treatment on decreasing concentration heavy metal cadmium (Cd) was treatment A 98,7%, tretment B 97,1%, treatment C 97,2 % and treatment D 95,8%.

Abstract

Kappaphycus alvarezii is one of Indonesia's export commodities because it has high economic value as food and industry. One area in East Java which is the center of seaweed cultivation is Sumenep regency such as Saronggi and Bluto. Currently Sumenep Regency is an area for oil and gas exploration and exploitation. Types of pollutants resulting from these activities cause pollution in aquatic environments such as lead (Pb), mercury (Hg) and cadmium (Cd). The heavy metals found in the waters can be absorbed and accumulated in the seaweed thallus. The purpose of this research is to know the heavy metal content of Pb, Hg, Cd, chlorophyll-a, and cell morphology in E. cottonii in Bluto and Saronggi waters. This research is survey and descriptive research. The results showed that there are differences in heavy metal content of lead in E. cottonii, seawater, and sediments in Bluto waters and Saronggi waters. The waters of Bluto have a lower amount of chlorophyll-a than the Saronggi Waters. Cell wall thickness in E. cottonii in Saronggi Waters has thinner cell walls than Bluto waters. Measurement of water quality in Bluto and Saronggi waters through temperature, pH, salinity, brightness and DO parameters. The measurement results from both waters are not any striking difference and under optimal conditions.

Abstract

Lapisan sedimen merupakan lapisan yang dihasilkan oleh proses pelapukan dan pengendapan yang salah satunya disebabkan oleh air. Lapisan sedimen ini mudah terdeformasi. Semakin tebal nilai ketebalan lapisan sedimen maka resiko yang timbulkan akbit gempabumi akan semakin besar pula. Penelitian ini telah dilakukan  di kawasan perbukitan Kecamatan Wangi-wangi Kabupaten Wakatobi  yang bertujuan untuk mengetahui sebaran nilai ketebalan lapisan sedimen menggunakan data mikrotremor dan nilai kecepatan gelombang shear (VS) hingga 30 meter (VS30) dari website data USGS. Data mikrotremor dianalisis menggunakan metode HVSR. Parameter yang diperoleh yaitu frekuensi dominan (f0) dengan kisaran nilai antara antara 0,63-11,35 Hz, dan paramer faktor amplifikasi (A0) dengan kisaran nilai antara 1,49-3,57. Adapun nilai VS30 dari website USGS yang telah diekstrak nilainya berkisar antara 291-552 m/s dan untuk nilai ketebalan lapisan sedimen yang diperoleh berkisar antara 11,65-215,62 meter  dimana untuk ketebalan sedimen tinggi terletak pada TP3 dan TP5 dengan nilai ketebalan 147,64-215,61 meter. Secara kualitatif semakin tebal lapisan sedimen maka resiko kerusakan akibat gempabumi akan semakin tinggi pula. Oleh karena itu daerah dengan resiko besar terletak pada sebagian kecil Tindoi Timur, sebagian kecil Posalu, sebagian kecil Maleko, sebagian kecil Pookambua, sebagian kecil Tindoi dan sebagian besar WaginapoKata kunci: Mikrotremor, HVSR, Ketebalan Lapisan Sedimen, Kecamanatan Wangi-wangi
