Abstract

Kalimantan Timur (Kaltim) merupakan daerah yang memiliki potensi kelautan dan perikanan prospektif.  Kabupaten Kutai Barat memiliki potensi perikanan berupa perairan umum yang besar untuk dikembangkan.  Konsumsi ikan dari tahun ke tahun mengalami peningkatan, sementara potensi perikanan belum dimanfaatkan dengan optimal.  Kendala dan permasalahan yang menjadi perhatian oleh kelompok mitra hingga saat ini adalah belum banyak petani pembudidaya ikan yang menguasai teknologi budidaya ikan dengan baik dan benar.  Tujuan dari kegiatan ini adalah penerapan dan transfer ilmu pengetahuan dan teknologi (ipteks) serta keterampilan dalam aplikasi teknologi pemijahan dan pembenihan ikan melalui penyediaan benih ikan secara mandiri untuk peningkatan produksi ikan air tawar pada kelompok mitra,  Pendekatan metode kegiatan dilakukan melalui beberapa tahapan, yaitu pemetaan kondisi dan permasalahan yang dihadapi oleh kelompok mitra, penyampaian materi terkait  teknologi pembenihan ikan, teknologi penijahan dengan menggunakan teknologi induce spawning (TIS) ikan dalam budidaya ikan air tawar serta monitoring dan evaluasi serta pendampingan pada kelompok mitra.  Hasil kegiatan penijahan dengan TIS memberikan hasil bahwa induk ikan mas dan ikan lele yang disuntik dengan hormon (ovaprim) memijah seluruhnya. Suhu media air terukur 26-28oC.  TIS ini dapat membantu masyarakat dalam penyediaan benih ikan dengan menjaga kualitas benih tetap baik dengan menerapkan cara pembenihan yang baik.

Abstract

Study aims to analyze the genotoxic potential of glyphosate-based herbicide on common carp (Cyprinus carpio L) using Micronucleus and hematological assay. The concentration of Glyphosate-based herbicide in this study was 0 ppm, 1.35 ppm, 1.8 ppm, 2.4 ppm, 3.2 ppm, 4.2 ppm, 6.5 ppm, and 8.7 ppm. Administration of herbicide base on modification of published methods with 96 hours of exposure. This research result has shown that the average number of micronuclei was increased simultaneously with increasing the concentration of herbicide exposure. There are also other types of cell nucleus abnormalities, namely: blebbed, lobed, notched, and binuclear. In the treatment of 0 ppm of herbicide shown blebbed nuclei are 8 ‰, lobed nuclei are 6.6 ‰, notched nuclei are 10 ‰, binuclei is 4 ‰. From the research results, it can be concluded that the LC50-96 hours exposure of the herbicide isopropylamine glyphosate in carp (Cyprinus carpio L.) was obtained at a concentration of 8.57 ppm. Based on the evaluation on hematology, it was found that there was a decrease in the number of erythrocytes, hematocrit, and hemoglobin of fish blood, whereas the number of leukocytes, micronuclei, and other abnormal micronuclei showed an increase along with the increase in the dose of exposure to the herbicide isopropylamine glyphosate, which indicates a genotoxic effect.

Abstract

Manyar Sub-district, located in Gresik, is home to many fish and shrimp pond farmers. Vannamei shrimp farming is a particularly popular aquaculture activity in Tanggul Rejo Village, Manyar Sub-district. However, the shrimp and fish farming industries face challenges in production, primarily due to diseases arising from declining water quality. Many pond farmers lack knowledge about the importance of water quality management to support successful shrimp farming, highlighting the need for appropriate technology to improve production. This study aimed to apply probiotics to manage the water quality of vannamei shrimp rearing media in Manyar Sub-district. The activity was carried out in several stages, including identifying and mapping the problems faced by farmers, delivering educational materials about the use of probiotics in shrimp farming, providing assistance for probiotic application, and monitoring and evaluating the results. The findings showed that the application of probiotics to the rearing water media every two days resulted in low ammonia and nitrite levels, as well as adequate oxygen levels and pH, which are conducive to vannamei shrimp cultivation.

Abstract

Tembang fish (Sardinella fimbriata) is the dominant and economical fish catch at Technical Unit of Bulu Coastal Fisheries Port (CFP) and is delivered to Bulu Fish Auction Site (FAS) or known as TPI Bulu. Tembang fish has perishable food characteristics, so it is necessary to improve the quality of freshly caught fish by maximising handling methods, facilities, and sanitary hygiene. Fishermen in TPI Bulu still rarely apply cold chain to maintain fish quality and some use formalin because it is easily available and cheap. This study aims to determine the quality of tembang fish at TPI Bulu. Testing parameters include organoleptic test, pH test, TPC test, and formalin test. The results of the research on 90 tembang fish samples obtained an average organoleptic value of 7.00 and pH 6.16. The formalin test results were 32 samples (35.6%) positive for formalin and 58 samples (64.4%) negative for formalin. The average TPC test result was 4.7 x 105 CFU/gr. The results of the inspection of Good Fish Handling Methods (GFHM) 30% of the criteria were fulfilled and 70% of the criteria were not fulfilled.
