This research was aimed to determine the width area of an intensive shrimp farm which can be supported by water environment of Banyuputih Sub-District, Situbondo Regency according to the water assimilation capacity towards the farm’s organic waste. We used survey method and secondary data collection from other researches or result report of relevant institution. This study was using two approaches of environmental carrying capacities, i.e. (1) quantitative method on available water volume in coast (coastal water) and (2) quantitative method on available Dissolved Oxygen (DO) in waste receiving water body of coastal water. The result showed that the utilization of coastal area for intensive shrimp farm activities in this study area is not exceeding its carrying capacity of water yet. Based on the analysis, the water environmental carrying capacity for the farm’s organic waste is 375.637 kg TSS. Organic waste (TSS) disposed from an intensive shrimp cultivation at the study area is 6.506 kg TSS.ha-1.MT-1. The width of intensive area which can be supported by Banyuputih Situbondo water environment is 58 ha. The width of available intensive pond area at study site is 113 ha, but only 39 ha is active/productive, the remaining 74 ha is inactive/unproductive area. If unproductive area will be re-operated/reactivated again, then we would recommend only 19 ha according to the water environment carrying capacity for the farm’s organic waste (58 ha). Estimation result of water environment carrying capacity for this organic waste of shrimp farm can be used as reference to determine the development or management threshold of sustainable pond area at this study site. Keywords: environment carrying capacity, organic waste, shrimp farm

Vaname shrimp is one of the leading cultivations of fishery production commodities in Indonesia which has high selling price and market share, also relatively resistant with high stocking density. Cultivation activities of this commodity can be carried out through three systems; namely traditional, semi-intensive, and intensive system. One group of cultivators who develop shrimp farming business is Mina Nusantara group in Lamongan District, where the cultivation system is still performed traditionally. The shrimp size was not uniform, and the survival rate was low once it harvested. Moreover, community empowerment was applied to increase vaname productivity towards semi-intensive system by culture potential analyses using SWOT and self-feed production training. Survey and experimental approach were used during the activities. The activities included survey and discussion with shrimp local farmer (Mina Nusantara), identified internal and external factors of culture by using SWOT analysis, carried out self-made artificial feed training, and program evaluation at the end. The activity resulted an increasing of farmer understanding of various culture system and they can produce the pellet in small scale by themselves. Based on SWOT analysis, the culture is potential to develop sustainably by regarding both internal and external factors.

Intensive shrimp farms need mangroves to increase the carrying capacity of their waters. Every 1 Ha of intensive shrimp pond requires 7.2 Ha mangrove to absorb nitrogen (N) and 21,7 Ha to absorb phosphor (P) from waste water disposal. This study was conducted to estimate the extent of lmangrove required to absorb nitrogen (N) and phosphorus (P) wastes removed from intensive shrimp farming in Banyuputih Subdistrict of Situbondo Regency. From the field survey results obtained data on the area of productive intensive ponds in the District Banyuputih is 39 Ha. The result of data analysis indicate that 280,3 Ha mangrove is needed to support the absorption of nitrogen (N) and 846,3 Ha mangrove to absorb phosphorus (P) of effectiveness pond waste pond in the study area. The mangrove in this subdistrict of Banyuputih (540,18 Ha) still support in the absorption of nitrogen waste (N), but for the absorption of phosphorus posfor (P) ponds still needed reforestation of at least 304,12 Ha from the existing mangrove area. If the local government intends to develop intensive shrimp ponds in accordance with the carrying capacity or maximum capacity of coastal waters of Banyuputih in decomposing 58 ha of tambak organic ponds, the current mangrove condition (540.18 Ha) still supports the absorption of nitrogen (N) from ponds intensively covering an area of 58 Ha, but to absorb the posfor (P) lagoon is still needed addition (reforestation) of 718.42 Ha.

Panen parsial adalah metode panen sebagian biomassa udang pada saat kegiatan operasional budidaya sedang berlangsung. Tujuan dari penelitian ini adalah menentukan konseptual model optimalisasi pengelolaan budidaya udang vannamei (L. vannamei) pola intensif berdasarkan prosentase estimasi panen parsial. Penelitian ini dilaksanakan dengan konsep desain kausal ex-post facto selama satu siklus budidaya intensif udang vannamei (L. vannamei). Hasil dari penelitian menunjukkan, selama masa budidaya parameter kualitas air yang meliputi pH, suhu, oksigen terlarut, nitrit, dan nitrat masih berada dalam ambang batas, sedangkan posfat, TAN, dan TOM berada diatas level ambang batas baku mutu untuk budidaya udang intensif. Untuk konsep model simulasi pengelolaan budidaya intensif dari skenario panen non-parsial, parsial 10%, dan parsial 20%. Sistem panen parsial 10% memiliki beberapa keunggulan dibandingkan dua sistem panen lainnya. Yakni, dengan diterapkannya simulasi panen parsial 10% didapatkan nilai efisiensi biomassa panen sebesar 88.08 kg dan efisiensi prosentase survival rate udang sebesar 11% dibandingkan dengan konsep panen parsial 20% atau non-parsial. Sehingga dapat disimpulkan, bahwa untuk konsep model pengelolaan budidaya udang vannamei (L. vannamei) pola intensif yang paling optimal berdasarkan hasil simulasi sistem pemodelan dinamis adalah konsep model budidaya panen parsial 10% dengan pelaksanaan panen parsial pada saat budidaya umur 60 hari.

Sardinella fish (Sardinella lemuru) is a species of important pelagic fish from the family of Clupeidae found in Bali Strait. The dynamic condition of Bali Strait makes it fertile which is identical with plankton blooming. The objective of this research was to understand the potential of saxitoxin in sardinella fish because of dinoflagellates consumption in Bali Strait. The research was conducted in Southeast Monsoon (June - August 2015) and Northwest Monsoon (December 2015 – February 2016). The method used was in situ plankton sampling, counting and ELISA test to determine the level of saxitoxin in the fish. Hydro-oceanographic parameters measured were temperatures, salinity, DO (dissolved oxygen), pH level, phosphate level, nitrate level and transparency. They showed average optimum value for phytoplankton growth especially during Southeast Monsoon which its temperature lower and the nutrients (phosphate nitrate) higher than the Northwest Monsoon. This condition caused high richness of phytoplankton in the water and followed with dinoflagellates richness so they accumulated in sardinella fish. It was supported by the analysis of the fish gastric which showed positive correlation between dinoflagellates richness in the water and the fish gastric. ELISA test also showed that saxitoxin level of fish caught in Southeast Monsoon was higher than the one caught in Northwest Monsoon even though the level of saxitoxin was still in the safe range (less than 80 μg STXeq. per 100 g) but the danger of saxitoxin accumulation should be watched out for.

The abundance of Vibrio bacteria and the presence of an excess Oscillatoria sp plankton type are the main problems that often arise in intensive vanamei (Litopenaeus vannamei) shrimp culture. To examine this problem, the purpose of this study was to determine of model approach interaction between the abundance of Vibrio and Oscillatoria sp with the shrimp growth rate in ponds. This research was conducted with the ex-pose facto design on intensive shrimp culture operations in Bayeman Village, Probolinggo. The results data from field research variable are analyzed using a dynamic modeling system. From the modeling analysis results, showed that the Oscillatoria sp abundance pattern tended to increase over with shrimp culture period as following the pattern of tropical status dynamics by the nutrient increase load of 16.37%/week in ponds ecosystem. Meanwhile, the increase of Vibrio colonies density in ponds continued to increase aggregately by 0.99%/week on nine weeks and 12.5% / week on the last eight weeks of shrimp culture periods. So, it can be concluded that the fluctuations density of vibrio and Oscillatoria sp bacteria in ponds is are bioecological responses from increased nutrient loads and other micromaterials in ponds due to the longer period of shrimp culture.
