Abstract

Penelitian Ini dilaksakan pada bulan Februari – Maret 2022, bertempat di Laboratorium Basah Fakultas Perikanan Universitas Dharmawangsa. Penelitian ini bertujuan untuk mengetahui pengaruh, dosis dan indeks keanekaragaman dalam pemberian debok pisang dan ekstrak kacang panjang dengan dosis yang berbeda terhadap kepadatan kultur infusoria. Metode yang digunakan pada penelitian ini adalah metode Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan. perlakuannya yaitu : P1= Kontrol (tanpa perlakuan), P2 = Debok pisang 110 gr, P3 = Ekstrak kacang panjang 110 ml/l, P4 = Kombiansi antara debok pisang dan ekstrak kacang panjang 55 gr - 55 ml. Berdasarkan hasil penelitian kepadatan sel tertinggi infusoria yaitu P3 sebanyak (357,66x104 sel/ml), sedangkan untuk kepadatan yang terendah yaitu di P1 sebanyak 16,33x104 sel/ml). Dan untuk laju pertumbuhan harian yang tertinggi yaitu pada perlakuan P3 sebanyak 3,76 sel/ml/hari, dan yang terendah terdapat di P1 sebanyak sebanyak 2,08 sel/ml/hari. Pada penelitian ini, terdapat 2 jenis infusoria yaitu Paramecium sp dan Volvox sp. Kesimpulannya yaitu pengaruh pemberian debok pisang dan ekstrak kacang panjang dengan dosis yang berbeda menunjukan bahwa FHit > FTabel yaitu: 54,936 > 7,59 pada taraf 1% yang berarti berpengaruh sangat nyata (higly-significant) terhadap populasi serta kepadatan infusoria

Abstract

This research was conducted in February-March 2023, at the Dharmawangsa University Laboratory. The purpose of this study was to determine the effectiveness of fish meal substitution using maggot flour in floating pellets on growth, life expectancy of tilapia and FCR (Food Conversion Ratio). Tilapia is widely cultivated by the community so that it has economic value with high market demand. The high price of feed causes many farmers to suffer losses. To overcome the problem of losses, cultivators use maggot as a substitute for fish meal to be used as a local raw material which has the advantage of being relatively cheap, high protein and increasing the digestibility of fish. The research method used experimental methods with the treatment of artificial feeding with fish meal protein sources and maggot flour protein sources and analyzed using the T test. The results of absolute growth research on fish meal pellets were 3.5 and maggot flour pellets 3.6. This shows that maggot flour can be used as a local raw material in the manufacture of fish feed. The results of the survival rate of tilapia by giving fish meal pellets were 60% and giving maggot flour pellets was 55%. Fish meal pellets and giving maggot flour pellets show that they can support the basic needs of fish and can support fish life. The results of the study showed that the FCR value for fish meal pellets was 1.36 and for maggot flour pellets was 1.36.
