Forage demand can be supplied from rice straw which processed with certain feed technology innovation. Some advantages can be derived under this technology i.e. increasing nutrient content, optimizing the utilization, improving the efficiency and reducing production cost by minimizing feed cost. Ammoniation fermentation (amofer) as an applied technology could give solution over the limitation of rice straw availability. The objective of this research was to determine the potency of rice straw processed with amofer (amofer-rice straw) as raw material to formulate complete feed. The experiment was carried out with randomized block design with three treatments and six replications. Amofer treatment was carried out by adding urea 3% from the total material and then placed into plastic jar +12 liter and then incubated under an-aerobic process for 18 days. Fermentation material i.e. biology starter by 1% of total material was added at the ninth day. Dry Matter (DM) content resulted from each treatments was 87,28%, 85,96% and 84,61% for T1, T2 and T3, respectively. Crude Protein (CP) content was T1=24,48%, T2=21,04%; and T3=24,46%, Crude Fiber (CF) content was T1=31,30%; T2=31,30%; and T3=31,39%. Total Digestible Nutrient (TDN) for version 1 was T1=57,29; T2=56,19; and T3=56,89 and version 2 was T1=53,11%; T2=52,28%; and T3=51,10%. The average value of Non Nitrogen Free Extract (NNFE) was T1=23,49%; T2=28,08%; and T3=26,57%. The utilization of amofer as applicable technology is considered as the most appropriate method to increase the quality of rice straw by significantly increase nutrient content in term of crude protein (CP) and reduce crude fiber (CF) content. This increasing quality can be seen from the result of proximate analysis, NNFE and TDN content

The increase of fishery production nationally and internationally may impact on the potential emergence of a variety of environmental problems. The application of sustainable aquaculture is urgently needed by breeding fish for commercial purposes in a manner such that it has a minimum impact on the environment, contributing to the development of local communities and generating economic benefits. The design of the cage and farming practice in aquaculture activities are the important steps to ensure that farming activity is still observed in order to anticipate the risk of organic enrichment caused by the activities. The application of Integrated Multi-Trophic Aquaculture (IMTA) on the Stratified Double Floating Net Cage (SDFNC) integrated with biomonitoring are an appropriate solution to the ongoing productive farming practices. IMTA is an aquaculture practice using more than one species of biotas which have ecologically mutual relationship as a part of the food chain in the area at the same time. The application of IMTA allows farmers to get several aquaculture products in the same area without increasing the horizontal area of the farms. At first, the SDFNC has been applied for farming Cyprinus carpio and Tilapia niloticus as polyculture system in freshwater ecosystem of Rawapening Lake, Central Java. Its operation has been able to increase the production capacity of at least 75% of conventional cages. The application of SDFNC-IMTA using milkfish (Chanos Chanos), seaweed (Kappaphycus alvarezii), and white shrimp (Litopenaeus vannamei) has been able to minimize the impact and maintain the water ecosystem in the Gulf Awerange, South Sulawesi.
