The tiger shrimp culture in East Borneo is commonly performed using traditional pond system management. In this work, the objective was to evaluate the application of Boesenbergia pandurata and Solanum ferox extract supplemented as feed additives considering shrimp growth, survival rate, and meat quality culture in a traditional pond. There were three dietary groups that were stocked with 300 shrimp in this study. The shrimp were maintained in a pond, separated with a 3 × 3 m2 net. The dietary treatment applied was divided into three types, namely P1, without the extracts; P2, 20 mL kg−1 dietary supplementation; and P3, 30 mL kg−1 dietary supplementation in the diet. The findings revealed that the herb extract influenced the growth rate, feed efficiency, survival rate, and meat quality of the shrimp, mainly the amino and fatty acid contents in the shrimp meat. The 30 mL kg−1 herb extract dose in group 3 showed a higher growth performance and survival rate. In group 3, 98% of the shrimp could survive until the final study period, while 96% of shrimp survived in group 2, and 70% of the shrimp survived in group 1. These findings indicate that the phytoimmune (B. pandurata and S. ferox) extract can be utilized as a feed additive to improve the growth, survival rate, and meat quality of the shrimp.

East Kalimantan is one of nine provinces selected for mangrove rehabilitation until 2024. Despite disappointing, it needs to be confirmed that the mangrove ecosystem in East Kalimantan has shrunk from year to year. However, it is encouraging to know that there is still a hope for mangrove ecosystem rehabilitation. Mangrove rehabilitation is expected to have an impact not only on the environment, but also on economy, social aspect, and wisdom of the coastal communities in East Kalimantan. Ponds are designated for more than 70% of the Mahakam Delta's mangrove. Although traditional management is still in the progress of development, the community still uses extensification to increase shrimp production. Local community has developed two pond models, namely environmentally-friendly ponds in Muara Badak Subdistrict, trench pond model in Salo Palai village, and komplangan model in Muara Badak Ulu Village. This trial was carried out in 1 ha of pond area using a fish and shrimp polyculture system for four months. Traditional maintenance was performed without adding artificial feed, but fertilization and management were carried out to monitor water quality, growth, survival rate, and total production. Trench pond and komplangan models have good environmental condition, like total nutrient base on mangrove litter. Production from both ponds was excellent, exceeding 300 kg/Ha for all cultures or polyculture systems. Application of the silvofishery model with these two models was sufficient to restore the mangrove ecosystem. However, komplangan model have two functions, as a conservation area and shrimp pond in one place, while it is associated with aquaculture production and sustainability for mangrove forest.

The Mahakam Delta is a large mangrove ecosystem in East Kalimantan with a precious ecosystem and a massive mangrove species. Because of the conversion to shrimp aquaculture, the mangrove ecosystem has been devastated. This study looks at shrimp pond management in Salo Palai, Muara Badak, Kutai Kartanegara, East Kalimantan, using the traditional polyculture concept to increase pond productivity. The current shrimp pond condition was decreased water quality, substrate infertility, and natural food availability crisis. This model focused on traditional management, with a particular emphasis on pond preparation, polyculture, and used plant extracts. For 100 days, Penaeus monodon, Chanos chanos, Litopenaeus vannamei, Lates calcarifer, Scylla spp., and Gracilaria verrucosa were grown in the same time and pond. The yield from the pond was thrived: 332.14 kg/Ha. This concept can be used to restore mangroves, preserve the mangrove ecosystem, increase shrimp pond production, and protect the sea ecosystem; thus, this method achieves sustainable aquaculture.
