Improving Productivity of PANDU (Integrated Rice and Shrimp Farming System) towards Sustainable Aquaculture of Indonesia

PANDU (integrated rice and shrimp farming system) is the first research program in Indonesia with the application of rice mina in saline land. This program applies the only commodity of black tiger shrimp (Penaeus monodon) with INPARI 34 Salin Agritan and INPARI 35 Salin Agritan. The PANDU was implemented in the first period (2018) with shrimp production still low, i.e., an average of SR 12% due to biota infected with WSSV and stress due to pesticide effects application. This study aims to increase the value of productivity in the second period (2019) through the kaizen approach and fishbone analysis. The study lasted for three months (4 March-1 June 2019) at the Barru PANDU research site. The number of observation plots was two out of six fields. Some interventions are: improving the quality of human resources, improving water quality, improving feed management, replacing pesticides with biopesticide, and applying biosecurity. Parameters analyzed were: SR, FCR, ABW, SGR, length, and daily growth rate of shrimp, water quality: temperature, salinity, pH, alkalinity, DO, ammonia, nitrate, nitrite, and plankton. The results of implementing the intervention increase the average SR value in 2019 by 27.33% and the productivity value was increasing by IDR 4,571,500.00 from IDR 7,200,000.00 (2018) to IDR 11,771,550.00 (2019).
