Makassar Strait is a waters area with a large and relatively fertile water resource potential. The Makassar Strait area represents the confluence zone between the Pacific Ocean and Indian Ocean fish populations. The fertility of the waters makes this area one of the breeding zones for most aquatic biota. This study aims to map the catch of small pelagic fishes with water conditions in the Makassar Strait. The data used in this study was fish catches data from Makassar Strait waters from June to September 2021. Data on environmental conditions in the form of Sea Surface Temperature and chlorophyll-a concentration in the waters during the study period were obtained from the AQUA satellite with MODIS sensors, then combined with the Geographic Information System (GIS). The results of this study indicate that the sea surface temperature range in Makassar Strait waters was between 26.7°C–31.3°C and the concentration of chlorophyll-a was between 0.7 mg/m³ - 1.30 mg/m³. The highest catch points were at two points with the same catch of the purse seine, namely 4,000 kg at 118°51'E and 5°10'59"S and at 118°52'59"E and 5°3'S, while the lowest catch was 5 kg at 118°19'E and 4°57'S. It can be concluded that the presence of fish may be influenced by the water’s conditions favored by the target fish in the Makassar Strait. Abstrak Selat Makassar merupakan kawasan perairan yang memiliki potensi sumberdaya perairan yang cukup besar dan relatif subur. Kawasan Selat Makassar merepresentasikan zona pertemuan antara populasi ikan Samudera Pasifik dan Samudera Hindia. Kesuburan perairannya menjadikan daerah ini sebagai salah satu zona berkembang biak bagi sebagian besar biota perairan. Penelitian ini bertujuan untuk memetakan hasil tangkapan ikan pelagis kecil dengan kondisi perairan di Selat Makassar. Data yang digunakan dalam penelitian ini merupakan data tangkapan ikan dari Perairan Selat Makassar pada bulan Juni-September 2021. Data kondisi lingkungan perairan berupa Suhu Permukaan Laut dan konsentrasi klorofil-a perairan pada periode penelitian diperoleh dari satelit AQUA dengan sensor MODIS, kemudian dikombinasikan dengan Sistem Informasi Geografis. Hasil penelitian ini menunjukkan bahwa kisaran suhu permukaan laut di Perairan Selat Makassar antara 26,7°C–31,3°C dan konsentrasi klorofil-a antara 0,7 mg/m³ - 1,30 mg/m³. Titik tangkapan tertinggi terdapat pada dua titik dengan hasil tangkapan pukat cincin yang sama yaitu 4000 kg pada 118°51’BT dan 5°10’59”LS serta pada titik 118°52’59”BT dan 5°3’LS, sedangkan tangkapan terendah sebanyak 5 kg pada titik 118°19’BT dan 4°57’LS. Disimpulkan bahwa keberadaan ikan kemungkinan dipengaruhi oleh kondisi perairan yang disukai ikan target tangkapan di Selat Makassar.
The results of the analysis using GIS software produce a thematic map of land suitability for lobster culture of the Karamba Floating Nets system with the suitability category obtained by adding up the values of all parameters to get the final score so that the values obtained between classes (Ci) are obtained. The Ci value obtained was 0.7 with a maximum Result Score (SHB) score of 3.0 and a minimum value of 0.8. The suitability category is determined based on the range or class interval where the corresponding criteria (S) are in the class interval 1.6 - 3.0 and the criteria does not match (N) based on the SHB interval 0.8 - 1.5. The results of the suitability evaluation conducted in this study are the actual suitability or land suitability, where the resulting land suitability class is only based on available data, not considering social, economic, financial, and other aspects. The results of the land suitability analysis based on the suitability matrix of the merging results for the lobster culture of the KJA system obtained the appropriate criteria (S) of 71.06 ha and not suitable (N) of 89.15 ha.
This study aims to determine the impact of seaweed cultivation on the water quality of vannamei shrimp aquaculture ponds in the Suppa District, Pinrang Regency. This research was conducted for approximately 10 (ten) years in 2020. The research location was around the waters of the Suppa District, Pinrang Regency. includes preparation / preliminary observation in the field, determining sample points or selecting observation stations, collecting data in the field, taking samples then observing the laboratory, and making reports. Analysis of water quality for seaweed cultivation includes parameters of Salinity, Temperature, DO, pH, Nitrate and Phosphate. Based on laboratory tests, it is known that for analysis of seaweed cultivation water quality, the average value of each parameter is temperature 30 0c, Salinity 36 ppt, DO 6.44 ppm, pH 8.30, Flow 0.35 m / s, Brightness 58%, Nitrate 0.005 mg / l, and 0.00026 ppm Phosphate While the results of laboratory analysis of physical and chemical parameters in the area of vannamei shrimp pond cultivation in Suppa District, Pinrang Regency, it is known that the average value of each parameter is temperature 30 0c, Salinity 33 ppt, DO 6.0 ppm, pH 8.4, Nitrate 0.0061 mg / l, and Phosphate 0.0032 ppm. The analysis of the suitability of pond land based on the analysis carried out found that it was suitable for 727.66 ha. And the effect of seaweed cultivation is very good for its influence on the quality of white shrimp pond water.
The purpose of this research is to analyze the development strategy of seaweed cultivation to increase seaweed production in the coastal area of Suppa District, Pinrang Regency. This research was conducted in the coastal area of Supa District, Pinrang Regency from May to December 2021. Data collection methods include observations, interviews and documents. The data analysis used is a SWOT analysis. The results showed that the main factors for developing seaweed cultivation business strategies to increase production in the coastal areas of Suppa District, Pinrang Regency, are a) development of aquaculture, b) providing training in stages, c) providing consultations, d) optimizing existing production capacity, e) Expanding planting areas, f) optimizing production, g) increasing funding, h) expanding and maintaining marketing networks.
