“…Fish processing generates considerable amounts of waste in the form of edible and non-edible by-products. Assuming 45% of the live weight to be waste (Rai et al, 2010), it can be estimated that nearly 64 million tons of fish waste are generated annually. This waste is mainly composed of heads, viscera, bones and scales, and is rich in lipids and proteins.…”

Purpose:The biogas productivity potential of fish waste (FW) was evaluated. Methods: Batch trials were carried out in 1.3 L glass digesters kept in a temperature controlled chambers at 36.5˚C. The first order kinetic model and the modified Gompertz model were evaluated for biogas production. The Chen and Hashimoto model was used to determine the critical hydraulic retention time (HRT Critical) for FW under mesophilic conditions. The feasibility of co-digestion of FW with animal manure was studied. Results: The biogas and methane potential of FW was found to be 757 and 554 mL/g VS, respectively. The methane content in the biogas produced from FW was found to be 73% and VS removal was found to be 77%. There was smaller difference between measured and predicted biogas production when using the modified Gompertz model (16.5%) than using first order kinetic model (31%). The time period for 80%-90% of biogas production (T80-90) from FW was calculated to be 50.3-53.5 days. Similarly, the HRT Critical for FW was calculated to be 13 days under mesophilic conditions. The methane production from swine manure (SM) and cow manure (CM) digesters could be enhanced by 13%-115% and 17%-152% by mixing 10%-90% of FW with SM and CM, respectively. Conclusions: The FW was found to be highly potential substrate for anaerobic digestion for biogas production. The modified Gompertz model could be more appropriate in describing anaerobic digestion process of FW. It could be promising for co-digestion of FW with animal manure.

“…Peptida yang terbentuk selama fermentasi vicera ikan memiliki aktivitas antioksidan yang dapat mencegah oksidasi lipid (Sachindra dan Bhaskar, 2008;Raia et al, 2010). Fermentasi hingga hari ke-24 pada silase ikan rucah yang ditambah gula kelapa pasta menunjukkan tidak beraroma tengik (5,,612 mEq/kg lemak) yang awalnya sebelum fermentasi.…”

“…Hal ini disebabkan karena adanya penghambatan aktivitas lipase oleh asam laktat yang diproduksi bakteri asam laktat yang tumbuh selama fermentasi ikan rucah yang ditambah gula kelapa pasta. Menurut Raia et al (2010), menurunnya asam lemak bebas selama fermentasi menurunkan aktivitas lipase dengan menurunnya pH. GKP 0% GKP 15% GKP 30% GKP 45%…”

“…Menurut Raia et al (2010) melaporkan bahwa selama fermentasi ikan atau limbah ikan, hidrolisis protein jaringan diikuti dengan pelepasan minyak yang dihidrolisis oleh lipase dan fosfolipase menjadi asam lemak bebas. Kerusakan lipid pada ikan selama penyimpanan tidak hanya aktivitas lipase dari enzim jaringan tetapi dapat berasal dari mikrobia perusak (Ghaly et al, 2010;Gram, 2009).…”

ABSTRAKPenelitian ini bertujuan untuk mengkaji pengaruh aras gula kelapa pasta dalam ensilase ikan rucah secara fermentasi alami terhadap perubahan kimiawi. Ikan rucah (Pomadasys macullatus) giling dicampur dengan dengan gula kelapa pasta (0, 15, 30 dan 45%/kg ikan rucah segar) tanpa inokulasi dalam kantong plastik. Inkubasi dilakukan secara anaerob pada suhu ruang (29º±1ºC). Perubahan kimiawi (pH, asam laktat, amonia, non protein nitrogen, bilangan peroksida dan asam lemak bebas) diamati pada periode fermentasi 0, 4, 8, 12, 16, 20 dan 24 hari. Percobaan dilakukan dengan menggunakan rancangan acak kelompok untuk memilih jumlah gula kelapa pasta dan waktu fermentasi terbaik dalam ensilase ikan rucah. Ikan rucah segar dan produk fermentasi (silase ikan rucah) dianalisis proksimat (bahan kering, abu, protein kasar dan lemak kasar). Hasil mengidikasikan terjadi penurunan pH tetap konstan 4,4 setelah 16 hari fermentasi. Asam laktat, amonia, non protein nitrogen, bilangan peroksida dan asam lemak bebas selama fermentasi meningkat secara nyata karena perbedaan aras gula kelapa pasta dan waktu fermentasi. Disimpulkan gula kelapa pasta 15%/kg ikan rucah segar, merupakan campuran terbaik dalam fermentasi alami dengan waktu fermentasi 16 hari dan produk berpotensi sebagai bahan sumber protein (45% BK) dalam pakan ternak.Kata kunci: ikan rucah, gula kelapa pasta, silase, fermentasi. The Influence of Additional of Coconut Sugar Paste in Trash Fish Ensilage toSilage Quality (pH, lactic acid, ammonia, non-protein nitrogen, peroxide value and free fatty acid) was observed during fermentation period of 0, 4, 8, 12, 20 and 24 ABSTRACT The objective of this research was to analyze the effect of coconut sugar paste in naturally fermented trash fish ensilage on chemical change. Grinded trash fish (Pomadasys macullatus) was mixed with coconut sugar paste (0, 15, 30 and 45%/kg fresh trash fish) without inoculation in plastic bag. Anaerobe incubation was conducted at room temperature (29°±1°C). Chemical change

“…Fish oil can be extracted from fish viscera by a number of processes including: wet rendering, enzymatic hydrolysis, autolysis, dry rendering, solvent extraction, and supercritical fluid extraction [7][8][9][10][11][12][13]. Wet rendering extraction has been used extensively since it does not require the use of harsh chemicals and consequently preserve the natural state of the fish waste components, lower the extraction cost and does not possess harmful effect on the environment [11].…”
