Abstract

Penelitian ini bertujuan untuk mengetahui kualitas air pada budidaya kepiting bakau di Desa Kuala Indah Kab. Batubara. Penelitian dilaksanakan di Laboratorium Budidaya Perairan Fakultas Pertanian Universitas Asahan. Penelitian ini dilaksanakan pada bulan April sampai Mei 2023. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan enam kali pengamatan. Tambak sebagai perlakuan yang diteliti meliputi Tambak I (T1), Tambak II (T2), Tambak III (T3), Tambak IV (T4). Peubah amatan meliputi kualitas air pemeliharaan, pertumbuhan mutlak (lebar karapaks kepiting dan bobot kepiting) dan kelulushidupan kepiting bakau. Hasil penelitian menunjukkan bahwa kualitas air pemeliharaan kepiting bakau di Desa Kuala Indah Kec. Sei Suka, Kab. Batubara terbaik diperoleh dari tambak keempat (T4) dengan kisaran suhu 29 °C, pH 7,22, DO sebesar 4,33, kadar NO3 sebesar 0,67, kadar NO2 sebesar 0,05 dan kadar amoniak sebesar 0 ppm. Kualitas air berpengaruh terhadap pertumbuhan kepiting bakau dengan lebar karapaks hingga 6,68 cm dan bobot hingga 38,7 g pada tambak keempat. Kualitas air berpengaruh terhadap kelulushidupan kepiting bakau dengan persentase hidup sebesar 73,33% pada tambak keempat. Kualitas air di perairan Desa Kuala Indah Kecamatan Sei Suka Kabupaten Batubara cukup baik dan sesuai untuk budidaya kepiting bakau. Kata kunci: kelulushidupan, pertumbuhan mutlak, mangrove

Abstract

The aim of the research was to analyze the nitrogen and phosphorus content in sediments in the cultivation area of Toulimembet Village. This research method is "survey" determining sampling points "purposive sampling" taking into account that the research location is a fish cultivation area with a floating net system, and data is obtained using primary data and secondary data. Primary data collected were in situ measurements of water quality parameters (temperature, turbidity, TDS, pH, DO) in the Toulimembet Village cultivation area and sediment analysis (Nitrogen and Phosphorus) at the Manado Standardization Research Center Laboratory (BARISTAND). Secondary data was obtained from various sources such as journals and previous research reports. Based on research results in Toulimembet Village, Kakas District, Minahasa Regency, North Sulawesi Province, nitrogen (0.78-1.16%), phosphorus (0.04-0.08%), temperature (25.73-27.01°C), turbidity (4.03-4.90 NTU), TDS (0.160-0.164 g/l), pH (7.89-10.52), DO (7. 20-12.67 mg/L), ammonia (0.07 mg/L), phosphate (0.0030-0.0158 mg/L), nitrite (0.069-0.295 mg/L) are still suitable for cultivation activities. Keywords: Fish culture, water quality, floating net cage, eutrophication

Abstract

The fishery sector which has great profit prospects can still be developed by cultivating fish better by paying attention to the condition of the water quality. In fish farming, it is very important to study water quality conditions because water quality parameters are a limiting and life-supporting factor for the types of aquatic biota cultivated in a waters including tilapia (Oreochromis niloticus. This research was conducted to assess water quality, both physical, chemical, and aquatic biology of Lake Tondano to support the feasibility test activities of Lake Tondano waters for Cage Netting Cage cultivation media. The research method used was purposive sampling. Primary data comes from primary data which is the result of measurements of physico-chemical parameters of water quality directly in the field (in situ) and supported by secondary data on several physical and chemical parameters of Lake Tondano waters as well as data on water quality of the cultivation media with the Netting Cage system. The physical and chemical parameters of Lake Tondano waters at the three stations were analyzed using the suitability scoring method for the location of Tondano Lake waters to be used as a maintenance medium fish with a Stuck Net Containment system. The results of the study concluded that the physical and chemical quality of water in Urongo waters was suitable for net cage culture. Keywords: physical-chemical parameters, Lake Tondano, aquaculture, Nile tilapia
