The implementation strategy of Ecosystem Approach to Aquaculture (EAA) shrimp commodities in Pinrang District, South Sulawesi

This study aims to develop a strategy for the sustainability of shrimp aquaculture using an ecosystem approach or EAA in Pinrang Regency, South Sulawesi. A series of analyzes were carried out, namely the environmental carrying capacity analysis of aquaculture using pond environmental feasibility standards, analysis of critical factors for the sustainability of aquaculture using multidimensional scaling analysis, analysis of the sustainability status of aquaculture using pairwise comparison analysis and analysis of shrimp aquaculture management strategies based on EAA. using hierarchy process analysis. The results showed that the following strategies were needed: a) accelerating spatial planning and implementing programs in accordance with the directions for spatial use and control; b) institutional strengthening of capital cultivators in order to complement and improve facilities and infrastructure in accordance with the SOP; and c) increasing the level of education and providing a social and economic security system for members of the shrimp farming community

Effectiveness of Microwave Drying for Shrimp Aquaculture Sludge

The disposal of the shrimp aquaculture sludge requires large area and high amount of disposal cost. The improper treatment and disposal can cause soil and water pollution. Sludge drying is an effective solution to reduce the weight of sludge and eventually reduces the disposal cost. This study was aimed to assess the effectiveness of thermal treatment on drying shrimp sludge at different power and time of 270W, 450 W 630W and 60s to 390s, respectively. Heavy metals concentrations and chemical compounds were also determined. Results reveal that the best drying rate recorded were at power and time of 630 W and 240s, respectively. Fourier transform infrared spectroscopy spectrum (FTIR) shows that the main groups presence are aliphatic chains with double bonds, as well as carbonyl, hydroxyl and N–H groups in organic compounds. Sludge drying has proven to be effective in reducing moisture content and organic matters for shrimp aquaculture sludge. It could be considered as one of the alternative methods to handle sludge.
