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.

Abstract

Control of gonad maturation and spawning is a major problem in the development of shrimp and lobster cultivation. Reproductive technology in hatching this type of crustacean has not experienced significant development. Progesterone is a precursor of estrogen in vertebrates, which is also found in crustaceans and other invertebrates. While several crustacean reproductive hormones have been characterized, the identity and function of other reproductive hormones are still under investigation. In hormone analysis, the use of the Enzyme Linked Immunosorbent Assay (ELISA) method continues to grow, both for research purposes and clinical applications. This study aims to evaluate the concentration of the hormone progesterone in Panulirus versicolor lobsters of different sizes with a body weight range of 300-750g which are caught in the wild using the ELISA method. The hormone progesterone is measured in the ovaries, hepatopancreas and hemolymph. This research uses descriptive analysis methods. From using the ELISA method, the results of the parallelism test showed that the test sample curve was parallel to the standard curve. Absorbance and standard value recovery tests showed that the measured concentrations of the progesterone hormone in Panulirus versicolor lobsters were acceptable because they had an average recovery value of 98%. The precision testing results of the ELISA kit used show that the test prescription is good and acceptable based on the percentage of coefficient variation (%CV) from QC1 and QC 2 (<15%). The concentration value of the progesterone hormone in P. versicolor lobsters shows that there is a difference in concentration depending on body size, where in lobsters with a body weight of 650-750g, the concentration of the progesterone hormone in the hepatopancreas, ovaries and hemolin is 1.059 ng/ml, 0.357 ng/ml and 0.042 ng/ml. while at lower body weights, namely 300-350 grams, the concentration of the hormone progesterone is 0.753 ng/ml, 0.181 ng/ml, 0.010 ng/ml.
