The physicochemical studies were carried out to asses water resource in Mangara Bombang District, South Sulawesi in relation to their potential for shrimp aquaculture use. Water samples were collected from pond, coastal area and river and analyzed for pH, TSS, salinity, dissolved oxygen (DO), biodegradable organic matter (BOD), Ammonia (NH 3 -N), Nitrate (NO 2 -N), Nitrite (NO 3 -N), and Orthophosphate (PO 4 -P). The results revealed that Mangara Bombang District is suitable for the development of pond shrimp farm with values obtained for pH, Temperature, TSS, salinity, dissolved oxygen (DO), biodegradable organic matter (BOD), Ammonia (NH 3 -N), Nitrate (NO 2 -N), Nitrite (NO 3 -N), and orthophosphate (PO 4 3 --P) were 8.
This study aimed to investigate the dissemination level of Ulil Filtered Technology (TUF) and geo-membrane technology and factors influencing salt production in Pangkep. Purposive sampling was performed for data collection. Regression analysis was applied for data analysis. Revenue cost analysis (R-C ratio) was performed. Break Event Point analysis (BEP) was applied, and Pay Back Period (PBP) analysis was used. The results showed that salt farmers unfamiliar with TUF and geo-membrane technology ranged from 6.71 to 9.62%, reasonably know (36.53 - 37.76%) and know to use TUF and geo-membrane technology (53.85 - 55.53%). Cost and technology significantly affected salt production, including area and number of labourers. The business feasibility study showed that Revenue Cost Ratio (1.98), Break Event Point (IDR 4,735,276), and Pay Back Period (1.9 years), respectively.
Abstract. The climate anomaly was adapted through the adjustment of tiger shrimp stocking patterns and optimum use of locally endemic Phronima Suppa (PS) to suit the season. Thus, the batches period determined was adjusted to suit climate change dynamics, reducing the shrimp stocking density down to 10.000 -15.000 per ha and applying PS so the shrimp became tolerant of any environmental stress and pathogen infection. The knowledge of adaptation to climate anomalies, a learning outcome of the field school, managed to increase the average production of tiger shrimp to 217 kg/ha with an average receipt of IDR 22.60 million/ha.
Southeast Sulawesi region, especially the Palabusa waters area of Buton Regency, has become a center for cultivation of several economical species, one of which is the mabè pearl (Pteria penguin). This research was conducted with the aim of identifying the suitable area for the development of mabè pearl cultivation and determining the carrying capacity of the area in Palabusa waters in developing mabè pearl cultivation. This research was conducted in September to November 2020. The data collection was carried out in two parts, namely field and laboratory activities. The data obtained then were analyzed descriptively. The results of this study indicate that: (1) Physical, chemical and biological parameters in Palabusa waters indicate the potential site suitability for the development of mabè pearl cultivation are in the very suitable category (SS) is 128, 3 Ha, quite suitable (S) is 64,5 Ha and not suitable (N) is 47,7 Ha for mabè pearl cultivation; (2) The carrying capacity of Palabusa waters for the development of pearl mabè pearl culture is 847 units. Further research needs to be carried out, especially regarding social and economic aspects as well as other water quality parameters that affect the determination of the suitability of mabè pearl cultivation areas such as environmental pollution, waves and tides.
Beach tourism is one of the favorite attractions of the community, especially in Indonesia. Aside from being cheap, Indonesia's 70% natural condition is the oceans and coastal areas that make coastal tourism appear a lot. The tourism object of the Turtle Village is located in the Tulang Village of Barugaiya District in Selayar Island Regency. From the results of research and data processing on the Analysis of Potential Kampung Penyu areas for coastal tourism areas by conducting direct observations and quantitative descriptive methods through scoring that is high potential. For Conformity Value of Coastal Tourism by looking at a number of variables from 3 location points, the results show that the area is very suitable for coastal tourism activities. For carrying capacity or carrying capacity, location 1 can accommodate around 889 people / day for coastal tourism activities, location 2 can accommodate 816 people / day for beach tourism activities and location 3 can accommodate 351 people / day for beach tourism activities. By looking at the potential, suitability and carrying capacity, a Regional Development Strategy can be formulated, namely the need to socialize to the community the community's readiness to develop areas other than coastal tourism areas but also ecotourism and culture. This can be done using the Focus Group Discussion (FGD) between communities and StakeHolder to find obstacles, and problems that hinder the development and development of tourism areas generally in Bontomanai Sub-District and especially in Kampung Penyu Areas.
<p class="1"><span lang="EN-GB">The study aims to find out condition of soil quality in brackishwater ponds in Mangara Bombang Sub-district, Takalar Regency where the center for brackishwater farming development is built. Soil quality sampling used as the main requirements for brackishwater shrimp farming parameter consist of soil texture, pH, organic matter, nutrients and pyrite content. Supporting soil quality parameters in brackishwater shrimp farming are pH<sub>FOX</sub>, KTK, Cation (K, Ca, Na, and Mg), TSA, TAA, and redox. Sampling is then analyzed in laboratory to find out condition of soil parameters in brackishwater areas, Mangara Bombang coastal areas.<strong> </strong>Calculation of soil quality including pH<sub>FOX</sub>, KTK, Cation (K, Ca, Na, and Mg), TSA, TAA, and redox aims to find out eligibility for brackishwater shrimp farming. The findings indicate that in general, brackishwater soil quality in Mangara Bombang coastal areas, Takalar Regency is at the eligible limits, or the soil is capable of promoting brackishwater shrimp farming. <strong></strong></span></p>
Salt is one of the national strategic commodities. But until now the notional needs of salt have not been met by national salt production in the country, one of the efforts to increase salt production in the country is to optimize existing potential salt field. The island of tanakeke in takalar district of southern sulawesi province has a potential salt field, wich is not yet well watered. The reseach’s aims (1) to anayize potential land appropriations for the development of salt pans on tanakeke island (2) to analize the salt-farm development cost (3) to determine salt pond development strategies based on the characteristics of the research area. Research suggetts that the total potential land most suitable for development of salt pond at 1.106,58 ha or about 38,91 % of the total land on Tanakeke islands. Based on the financial analysis of the salt pond with geomembran method on an acre of land on tanakeke islands are feasible to continue. Followed by the investment criteria acquired by NPV>1, Net B/C>1 and IRR>discount rate. Selected combination of strategies (1) Priority strategies; Training in increased human resource capacity and Infrastructure improvements. (2) altenative strategies; salt regulatory improvements.
