Abstract

Catfish feed added with probiotics can affect the growth and health of fish. This study aims to determine the effectiveness of applying Probio_FmUBB to catfish growth. The research was conducted from September to November 2022 for catfish (Clarias sp.) growing-out in the floating fish cages (KJA) owned by CV. Dua Agri Mandiri (CV. DAM) in Petaling Village, West Mendo District, Bangka Regency, Kepulauan Bangka Belitung Province. The sampling method used simple random sampling of catfish in two ponds, fed with probiotic and non-probiotic feed. The results showed that feeds with the addition of the probiotic Probio_FmUBB make differences in the weight and length growth of catfish, where the fish grew faster and heavier than catfish fed with non-probiotic feed. Both catfish groups in the initial phase both showed rapid growth and slowed down in the adult phase. The final measurement showed that catfish with probiotic feed had an average weight of 28.5 grams and an average length of 112.8 cm, while catfish with non-probiotic feed had an average weight of 26.64 grams and an average length of 108.4 cm. It is assumed that the application of Probio_FmUBB probiotics on feed works effectively compared to feed without probiotics. The digestibility showed that the feed with Probio_FmUBB is absorbed  into nutrients more efficiently by catfish. The water quality in the earthen-pond KJAs shows values that are not considerably different and is still acceptable in the water quality standard criteria for fish farming. The water does not smell, and it is assumed that the ammonia decay at the pond bottoms is not high.

Abstract

Fish scales are leftover fishery products that are not utilized optimally. Fish scales contain chemical compounds such as organic protein, namely chitin, which is a derivative of chitosan. Chitosan can be used in various sectors such as the food industry, health, agricultural and cosmetics. This study aims to extract chitosan from the scales of farmed and marine fish, as well as to determine the ratio of the yield of chitosan to types of marine fish and cultivated fish. This research was conducted from July to August 2023. The fish scale samples used were tilapia (cultivated fish) and snapper (sea-caught fish) obtained from the Traditional Market and Fish Auction Place in Bengkulu City. The process of making chitosan is carried out in the Laboratory of the Faculty of Agriculture, Prof. Dr. Hazairin, SH University. The process of extracting chitosan from fish scales goes through three stages, namely deproteination, demineralization and deacetylation. The results showed that the water, ash and protein content of fish scales were different, namely tilapia (19.05%; 20.15%; 53.01%) and snapper. (10.78%; 43.54%; 28.49). Results of Tilapia Chitosan. (13.22%) and snapper (7.74%). Several chitosan characteristics such as color, shape and odor meet commercial chitosan standards.

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.

Abstract

Logam berat kadmium di perairan pada umumnya mempunyai sifat toksik dan berbahaya bagi organisme hidup, walaupun beberapa diantaranya diperlukan dalam jumlah kecil. Cd merupakan logam berat yang sangat berbahaya karena tidak dapat dihancurkan (non-degradable) oleh organisme hidup dan dapat terakumulasi ke tubuh organisme melalui rantai makanan. Tujuan dari penelitian ini adalah mengetahui pengaruh Cd pada reproduksi ikan nilem (Osteochilus hasselti C.V) jantan. Prosedurnya hewan uji disimpan di empat bak fiber yang mengandung Cd dengan kadar (0 mg/L [kontrol]; 2 mg/L [rendah]; 4 mg/L [sedang]; 6 mg/L [tinggi]) selama 4 minggu. Dampak dari Cd terhadap reproduksi ikan nilem dievaluasi dengan tingkat ekspresi gen cGnRH-II. Hasil penelitian menunjukkan bahwa pengaruh perlakuan kadmium selama 4 minggu terhadap nilai ekspresi gen cGnRH-II memiliki kisaran rata-rata antara 0,0036 - 0,3470. Pengaruh perlakuan selama minggu ke-2 dan ke-4 tidak memberikan pengaruh yang signifikan (P>0,05) dalam menurunkan nilai ekspresi gen cGnRH-II pada ikan nilem jantan, seiring dengan meningkatnya konsentrasi kadmium serta lamanya waktu pemaparan.
