Abstract

ABSTRAK Sistem Resirkulasi merupakan suatu metode pemeliharaan ikan dalam wadah terkontrol dalam menggunakan kembali air bekas setelah proses penyaringan secara fisik dan biologi. Salah satu bentuk sistem resirkulasi yaitu multi layer filter. Penelitian ini bertujuan untuk mengetahui parameter kualtas air dan tingkat kelangsungan hidup pada pemeliharaan ikan banggai cardinal (P. kauderni) dengan menggunakan variasi sistem resirkulasi multi layer filter. Kegiatan Penelitian ini dilaksanakan selama 1 bulan dari bulan februari – maret 2019 di Laboratorium Unit Kultivasi Program Studi Budidaya Perairan-Universitas Pattimura Ambon. Penelitian ini menggunakan desain wadah resirkulasi dengan 2 perlakuan sistem dan media filter yang digunakan yaitu dakron, arang aktif, pasir pantai, bioball, dan keramik mika. Data yang diperoleh kemudian dianalisa menggunakan analisis deskriptif, kemudian data tersebut diolah pada Microsoft office Excel 2010, disajikan dalam bentuk tabel dan grafik. Hasil penelitian ini menunjukan bahwa hasil pengukuran konsentrasi amonia yang diperoleh bahwa pada perlakuan B (Bioball, arang aktif, dakron, dan pasir) dapat mereduksi amonia lebih optimal dengan nilai konsentrasi di minggu terakhir yaitu 0.3 mg/l dan perlakuan ini dapat menjaga kelangsungan hidup ikan banggai cardinal berkisar 66.67 % lebih baik dibandingkan perlakuan yang lainnya. Dapat disimpulkan bahwa variasi komponen sistem resirkulasi multi layer filter pada perlakuan dengan kombinasi filter bioball, arang aktif, dakron dan pasir mampu mereduksi amonia, serta memberikan pengaruh yang lebih baik terhadap kualitas air sehingga mampu meningkatkan kelangsungan hidup ikan banggai cardinal.

Abstract

Strombus luhuanus is a gastropod that is commonly found in Maluku and is very popular with the local community because it has a high nutritional content. Lives in colonies and is abundant in shallow intertidal and subtidal areas at a depth of about 20 m. The aim of the study was to determine the composition of proximate, amino acids and fatty acids that have the potential as bioactive compounds in the field of pharmacology. The results of the proximate study of fresh meat of Strombus luhuanus contained 79.78% water content, 0.89%, ash 15.64% protein, 0.96% fat, 2.73% carbohydrates. Amino acids found included glutamic acid, aspartic acid, leucine, arginine, lysine, glycine, alanine, threonine, valine, serine, isoleucine, proline, phenylalanine, tyrosine, cystine, methionine, histidine and tryptophan. Fatty acids consist of saturated fatty acids and unsaturated fatty acids.

Abstract

The waters of Tanjung Tiram Village are one of the places for community coastal area activities, such as ship traffic, ship repair, and the construction of steam power plants that have the potential to cause pollution to the coastal environment so that it can reduce the quality of the environment in the area. This study aims to determine the content of heavy metals lead (Pb) and cadmium (Cd) in the sediment. Sampling was carried out in March 2021 at 4 (four) stations selected by purposive sampling. The samples were analyzed for heavy metal content of Pb and Cd using AAS (Atomic Absorption Spectrophotometry). The results of the analysis of the Pb content in the sediment ranged from 8.7416 to 8.4460 mg/L and the Cd content ranged from 0.3760 to 0.6338 mg/L, exceeding the maximum quality standard set by ANZECC/ARMCANZ.
