Abstract

Abstrak Sonneratia caseolaris merupakan jenis tanaman bakau yang banyak dimanfaatkan pada kegiatan akuakultur. tujuan dari penelitian ini adalah untuk mengetahui efektifitas penambahan ekstrak buah mangrove Sonneratia caseolaris yang dicampurkan pada pakan komersil untuk pemeliharaan ikan kerapu cantang (Ephinephelus fuscoguttatus X Ephinephelus lanceolatus). Metode penelitian yang digunakan pada penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan pemberian dosis perlakuan 5 mg/L, 15 mg/L, dan kontrol dengan masing-masing tiga pengulangan. Hasil penelitian menunjukkan perlakuan 15 mg/L ekstrak buah pedada pada pakan komersil adalah dosis terbaik. Hal tersebut dapat dilihat dari nilai biomassa rata-rata 37.78 gr, feed conversion ratio 1.10, survival rate 100%, dan efisiensi pemanfaatan pakan sebesar 90.26%. Selain itu parameter kualitas seperti pH 7.9, oksigen terlarut 5.88 mg/L, suhu 29 0 C, dan salinitas 31 ppt secara keseluruhan masih sesuai baku mutu air untuk kegiatan budidaya ikan air payau. Perlakuan lain yaitu 5 mg/L dan kontrol juga cukup progresif, tetapi tidak seefektif perlakuan 15 mg/L. Kesimpulan penelitian ini adalah Penambahan ekstrak buah mangrove Sonneratia caseolaris pada pakan komersil ikan kerapu cantang dinilai cukup efektif dengan pengambilan dosis ekstrak sebesar 15 mg/L. Indikator nyata yang dapat dilihat adalah nilai parameter biomassa ikan, feed conversion ratio, survival rate, dan efektifitas pemberian pakan. Abstract Sonneratia caseolaris is a type of mangrove plant that is widely used in aquaculture activities. the purpose of this study was to determine the effectiveness of the addition of Sonneratia caseolaris mangrove fruit extract mixed in commercial feed for the maintenance of cantang grouper (Ephinephelus fuscoguttatus X Ephinephelus lanceolatus). The research method used in this study was a completely randomised design (CRD) with treatment doses of 5 mg/L, 15 mg/L, and control with three repetitions each. The results showed that the treatment of 15 mg/L of pedada fruit extract in commercial feed was the best dose. This can be seen from the average biomass value of 37.78 g, feed conversion ratio of 1.10, survival rate of 100%, and feed utilisation efficiency of 90.26%. In addition, quality parameters such as pH 7.9, dissolved oxygen 5.88 mg/L, temperature 290C, and salinity 31 ppt are all still in accordance with water quality standards for brackish water fish farming activities. Other treatments, namely 5 mg/L and control, are also quite progressive, but not as effective as the 15 mg/L treatment. The conclusion of this study is that the addition of Sonneratia caseolaris mangrove fruit extract to commercial feed for cantang grouper is considered quite effective by taking an extract dose of 15 mg/L. The real indicators that can be seen are the parameter values of fish biomass, feed conversion ratio, survival rate, and feeding effectiveness.
