Abstract

ABSTRAKKadmium (Cd) merupakan salah satu jenis logam berat pencemar di suatu badan perairan yang dapat bersumber dari limbah bahan bakar dan kegiatan industri. Tempat Pelelangan Ikan (TPI) yang didalamnya terdapat berbagai aktivitas masyarakat dan juga lalu lalang kapal nelayan berperan menyumbang masukan logam berat Cd ke perairan dan biota. Penelitian dilakukan pada Februari-Maret 2022 untuk mengetahui hubungan kualitas air dengan kelarutan logam Cd; kadar logam Cd pada air, sedimen, dan ikan bawal (P. argenteus) di sekitar TPI Branta, Kabupaten Pamekasan. Kajian secara deskriptif menunjukkan adanya hubungan yang berbanding lurus antara suhu dan tingkat kecerahan perairan dengan tingkat kelarutan logam berat Cd. Sedangkan hubungan pH serta salinitas menunjukkan hasil berbanding terbalik terhadap tingkat kelarutan Cd. Kadar Cd pada air laut sebesar 0,0023 mg/L; sedimen berkisar antara 0,0138-0,0179 mg/L; dan pada ikan bawal (P. argenteus) berkisar 0,0015-0,0019 mg/L. Meninjau baku mutu air laut dan batas logam berat pada pangan, kadar Cd air laut, sedimen dan ikan bawal masih memenuhi baku mutu dengan nilai BAF dan BSAF sebesar 0,7435 dan 0,1084. Batas maksimum konsumsi ikan bawal (P. argenteus) pada orang dewasa sebesar 4631,3 kg/minggu, sedangkan pada anak-anak sebesar 27546,4 kg/minggu.Kata Kunci: logam berat kadmium, Pampus argenteus, batas maksimum konsumsiABSTRACTCadmium (Cd) is a type of heavy metal pollutant in a body of water which can be sourced from fuel waste and industrial activities. The Fish Auction (TPI), in which there are various community activities and also the passing of fishing boats, plays a role in inputting the heavy metal Cd into the waters and biota. The research was conducted in February-March 2022 to determine the relationship between water quality and Cd metal solubility; levels of Cd metal in water, sediment, and pomfret (P. argenteus) around TPI Branta, Pamekasan Regency. Descriptive studies show that there is a directly proportional relationship between temperature and the brightness level of the waters with the solubility level of the heavy metal Cd. Meanwhile, the relationship between pH and salinity shows an inverse relationship with the solubility level of Cd. Cd content in seawater is 0.0023 mg/L; sediment ranged from 0.0138-0.0179 mg/L; and in pomfret (P. argenteus) it ranges from 0.0015 to 0.0019 mg/L. Looking at seawater quality standards and heavy metal limits in food, Cd levels of seawater, sediment and pomfret still meet quality standards with BAF and BSAF values of 0.7435 and 0.1084. The maximum consumption limit for pomfret (P. argenteus) for adults is 4631.3 kg/week, while for children it is 27546.4 kg/week.Keywords: heavy metal cadmium, pomfret, maximum consumption limit

Abstract

AbstrakSampah plastik merupakan masalah besar di dunia yang akhirnya menimbulkan adanya mikroplastik pada lingkungan perairan dan menyebabkan beberapa dampak bagi lingkungan perairan. Mikroplastik yang masuk ke dalam perairan akan masuk ke dalam badan air dan akhirnya akan mengendap pada sedimen. Kawasan hutan mangrove menjadi tempat hidup biota yang terdapat pada kawasan tersebut. Maka perlunya adanya kajian mikroplastik pada kawasan Pantai Wisata Hutan Mangrove Desa Labuhan dengan tujuan mengetahui karakteristik sedimen, mengetahui kelimpahan dan bentuk mikroplastik, serta mengetahui hubungan antar tekstur sedimen dengan kelimpahan mikroplastik. Pengambilan sampel dilakukan pada bulan September-November 2021, pengambilan sampel dilakukan pada 5 stasiun dan 3 titik pada setiap stasiun. Parameter yang dianalisis adalah tekstur sedimen, kelimpahan dan bentuk mikroplastik serta hubungan antar kelimpahan mikroplastik dengan tekstur sedimen. Hasil yang diperoleh yaitu pada kawasan mangrove memiliki karakteristik tekstur sedimen lumpur berlempung. Kelimpahan mikroplastik pada air sebesar 9-168 partikel/50 L, sedangkan kelimpahan mikroplastik yang ditemukan pada sedimen sebanyak 17-36 partikel/50 gram sedimen kering. Bentuk mikroplastik yang ditemukan yaitu fiber, fragmen, dan film. Bentuk fiber merupakan bentuk paling mendominasi pada air dan sedimen.Kata Kunci: Kelimpahan Mikroplastik, Tekstur Sedimen, MangroveAbstractPlastic waste is a big problem in the world that causes microplastics in the sky environment and causes several impacts on the aquatic environment. Microplastics that enter the waters will enter the water body and will eventually settle in the sediment. The mangrove forest area is a place to live for the biota found in the area. So it is necessary to study microplastics in the Mangrove Forest Tourism Beach area ofLabuhan Village with the aim of knowing the characteristics of sediment, knowing the shape and shape of microplastics, and knowing the relationship between sediment texture and microplastics. Sampling was carried out in September-November 2021, sampling was carried out at 5 stations and 3 points at each station. The parameters analyzed were the texture of the sediment, the shape of the microplastic, and the relationship between the microplastic and the texture of the sediment. The results obtained are that the mangrove area has a characteristic texture of loamy mud sediments. The abundance of microplastics in water was 9-168 particles/50 L, while the number of microplastics found in sediments was 17-36 particles/50 grams of dry sediment. The forms of microplastics found were fiber, fragments, and films. The form of fiber is the most dominant form in water and sediment.Keywords: Microplastic Abundance, Sediment Texture, Mangrove

Abstract

ABSTRAKIkan mas adalah salah satu ikan air tawar yang bersifat herbivor. Pakan sebagai sumber nutrien dalam pembesaran ikan mas umumnya terbuat dari beberapa campuran bahan baku nabati. Penggunaan bahan baku nabati tanpa pengolahan dapat menurunkan pertumbuhan ikan karena kandungan serat dan zat antinutrisnya yang relatif tinggi. Cairan rumen sapi merupakan salah satu bahan kaya akan enzim dan mikroorganisme yang berperan dalam menurunkan serat kasar dan zat antinutrisi pada bahan nabati pakan. Penelitian ini bertujuan untuk mendapatkan dosis cairan rumen sapi yang tepat sebagai bahan fermentasi pada seluruh bahan nabati pakan dalam meningkatkan pertumbuhan dan kelangsungan hidup benih ikan mas. Penelitian didesain menggunakan rancangan acak lengkap. Perlakuan yang diujikan yakni dosis penggunaan cairan rumen sapi (0%, 25%, 50% dan 75% dari bobot bahan nabati pakan). Hasil analisis menunjukkan bahwa penggunaan cairan rumen sapi sebagai bahan fermentasi bahan nabati dalam pembuatan pakan memberikan pengaruh nyata (p0,05) terhadap laju pertumbuhan spesifik harian (LSPH), pertambahan bobot individu (PBI), rasio konversi pakan (RKP). LSPH dan PBI tertinggi serta RKP terendah diperoleh pada perlakuan dosis cairan rumen sapi 75% per bobot sampel bahan nabati yakni secara berurut sebesar 2,87 % hari-1, 1,18 g dan 1,77. Kelangsungan hidup selama pemeliharaan untuk semua perlakuan berkisar antara 66,67-80,0%. Kualitas air selama pemeliharaan meliputi pH (5,8-8,1), suhu (28-30 ºC), oksigen terlarut (5,0-6,8 ppm), dan amonia  (0,05-0,01 ppm) masih dalam kategori sesuai untuk pemeliharaan benih ikan mas. Dosis penggunaan cairan rumen sapi sebagai bahan fermentasi bahan baku nabati pakan yang memberikan nilai terbaik diperoleh pada perlakuan D (75% cairan rumen sapi).Kata Kunci: Bahan baku pakan, Kelangsungan hidup, Rasio konversi pakanABSTRACTThe carp (Cyprinus carpio) is a herbivorous freshwater fish. Feed as a source of nutrients in carp grow-out is generally made from a mixture of plant-based ingredients. The use of unprocessed plant materials can inhibit fish growth due to the relatively high fiber and anti-nutrient content. Bovine rumen fluid is rich in enzymes and microorganisms that can reduce crude fiber and anti-nutrient content in plant-based feed ingredients. This study aimed to determine the best dose of bovine rumen fluid used as a plant-based feed ingredient fermentation agent in terms of improving the growth and survival of carp fry. The study used a complete randomized design. The treatments trialed were various doses of bovine rumen fluid (0%, 25%, 50% and 75% of plant-based feed ingredients by weight). The results showed that using bovine rumen liquid to induce fermentation of plant-based feed ingredients during feed manufacturing had a significant effect (p0.05) on specific growth rate (SGR), individual weight gain (IWG), and feed conversion ratio (FCR). The highest SGR and IWG and the lowest FCR (2.87% day-1, 1.18 g and 1.77, respectively) were obtained under the bovine rumen fluid dose of 75% plant-based ingredient weight. Across all treatments, survival rate during the study period ranged from 66.67-80.0%. Water quality remained within suitable ranges for carp fry rearing, as follows: pH (5.8-8.1), temperature (28-30ºC), dissolved oxygen (5.0-6.8 ppm), and ammonia (0.05-0.01 ppm). The dosage of bovine rumen fluid that provided the best results when used as a fermentation agent for plant-based ingredients in carp fry feed was treatment D (75% bovine rumen fluid by weight).Key words: Feed ingredients, Survival, Feed conversion ratio.
