Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh media air yang berbeda yaitu air tanah, air gambut, air PDAM, dan air minum isi ulang (Ro) terhadap penetasan telur ikan lele dumbo (Clarias gariepinus). Penelitian ini dilaksanakan selama 1 (satu) bulan, pada bulan Juli sampai dengan Agustus 2020. Tempat pelaksanaan di Laboratorium Basah Jurusan Perikanan, Universitas Palangka Raya, Kalimantan Tengah. Hasil dari penelitian dapat disimpulkan sebagai berikut: Pemijahan ikan lele dengan perbandingan 1:1 menghasilkan jumlah pembuahan yang relatif tinggi mencapai 92 %. Presentase penetasan telur lele dumbo (Clarias gariepinus) terdapat pada perlakuan Air tanah (B) yaitu sebesar 69% dengan rata-rata pH sebesar 6,40 ± 0,20; diikuti perlakuan Air PDAM (C) sebesar 66,6% dengan rata-rata pH sebesar 6,43 ± 0,06; perlakuan Air isi Ulang Ro (D) sebesar 65,3% 6,83 dengan rata-rata pH ± 0,15 dan perlakuan Air Gambut (A) sebesar 63,3% dengan rata-rata pH 5,20 ± 0,20. Perlakuan berupa perbedaan media air yang terdiri dari Air Gambut, Air Tanah, Air PDAM dan Air isi ulang Ro yang digunakan untuk penetasan telur ikan lele (Clarias garphineus) menunjukkan tidak terdapat perbedaan yang nyata terhadap persentase telur lele dumbo (Clarias gariepinus) yang dihasilkan, dikarenakan presentase penetasan pada setiap perlakuan tidak terlalu berbeda jauh (63,3% - 69%) dan nilai Fhitung = 0.264 < Ftabel5% = 5.14, nilai Sig. = 0.774 > α = 0.05, karena nilai Sig. > α atau Fhitung< Ftabel maka disimpulkan bahwa H0 diterima atau ragam tidak berbeda nyata.

Abstract

BSF maggots (Hermetia illucens) also have quite high nutritional content, making BSF maggots able to be used as feed for fish. Maggot BSF works to convert organic waste into simpler biomass. Organic waste from agricultural waste is a medium for maggot enlargement that can be used as feed. Agricultural organic waste in Indonesia is available in quite large quantities. The types of waste that can be used as cultivation media are tofu waste and palm oil cake waste.  This study aims to determine the effect of the combination of fermented palm oil cake with natural organic decomposer and tofu waste on the growth rate of Maggot BSF (Hermetia illucens). The method used in this research is the experimental method using Completely Randomized Design (CRD). The factors studied were the combination of fermented palm oil cake with natural organic decomposer and tofu waste on the growth of Maggot BSF which consisted of 4 treatment levels, namely A (100% fermented palm oil cake); B (75% fermented palm oil + 25% tofu dregs); C (50% fermented palm oil + 50% tofu dregs); D (25% fermented palm oil + 75% tofu waste). Parameters observed were BSF maggot length and weight growth, digested feed conversion efficiency (ECD), waste reduction index (WRI), BSF maggot productivity.  Data used is Analysis of Variance (ANOVA) and to determine the best treatment using a follow-up test in the form of Duncan's test with a significance level of 5%. The results showed that the combination of fermented palm oil cake with different natural organic decomposers and tofu dregs had a significant effect on the productivity of BSF maggots. The best combination of fermented palm oil cake with natural organic decomposer and tofu waste on the growth rate of Maggot BSF is 100% fermented palm oil cake which has a significant effect when compared to other treatments.
