Central Java Government Proves Closed System Technology Success in Shrimp Harvest
Through technological engineering, this 1,561-square-metre pond has not only successfully produced high-quality shrimp but has also become a pilot model for modern pond revitalisation in the northern coast (Pantura) region.
The Head of the Central Java Marine and Fisheries Office, Endi Faiz Efendi, stated that the harvest took place in Plot B3 of Loka PBI Tugu. From a cultivation period of approximately 82 days, the production of vannamei shrimp is targeted to reach 1.3 tonnes, with a size of around 60 shrimp per kilogram.
Endi explained that the pond implements a closed system because it is located within an industrial area, necessitating minimal water usage. “We use very little water from external sources, which we then treat with dolomite, calcium hypochlorite, and aeration before it is used for cultivation,” he said in a written statement on Monday (6/7/2026).
Endi added that this harvest is being marketed to meet local demand at a price of approximately Rp60,000 per kilogram. Furthermore, Loka PBI Tugu continues to show positive performance, with realised regional original income (PAD) reaching approximately 72 per cent of the annual target as of the first semester of 2026.
On this occasion, the Governor of Central Java, Ahmad Luthfi, requested the Marine and Fisheries Office to accelerate the development of fish and shrimp hatchery centres. According to him, hatcheries are more beneficial to the community because production costs are lower, business turnover is faster, and they are capable of supporting food security.
Therefore, Luthability added that government-owned fisheries centres must serve as hubs for superior breeding that can be utilised by farmers in various regions. This ensures that the community no longer faces difficulties in obtaining high-quality seeds.
He also requested that all experts and extension workers within the Marine and Fisheries Office be more active in assisting the community, ranging from seed provision and cultivation guidance to the marketing of harvests. “So that the community will not have to look elsewhere. In this way, our department will truly be beneficial to the people,” he said.
Luthfi stated that the fisheries sector is a vital part of supporting the national food self-sufficiency programme. Central Java possesses a coastline spanning 17 regencies/cities, yet most pond areas are still managed traditionally and thus require revitalisation.
He revealed that he has coordinated with the Minister of Marine Affairs and Fisheries regarding plans to revitalise ponds along the North Coast of Central Java, covering an area of approximately 72,000 hectares. “In the near future, the Minister of Marine Affairs and Fisheries will provide full support for our North Coast region. The principle is that we will immediately oversee the process so that non-functional ponds can be brought back into operation,” he said.
