Abstract

Penelitian ini bertujuan menganalisis kelayakan perairan berdasarkan parameter fisika dan kimia perairan danau Paniai untuk kegiatan budidaya ikan. Penelitian ini merupakan penelitian deskriptif kuantitatif dengan mengkaji kondisi kualitas air perairan danau Paniai, Papua. Pengambilan dan pengukuran sampel air pada setiap lokasi sampling dilakukan dengan metode composite sampling (gabungan tempat). Contoh air danau diambil pada permukaan dan pertengahan. Pengukuran dan pengumpulan data dilakukan sebanyak 2 kali dengan interval waktu antar pengukuran selama 1 bulan. Hasil penelitian didapatkan parameter fisika masih memenuhi syarat baku mutu, parameter kimia, dari delapan parameter yang diukur terdapat 3 parameter yang tidak memenuhi baku mutu yaitu, H2S, Nitrat dan Posfat. Hal ini menunjjukan bahwa tingginya buangan limbah dari sektor pertanian dan rumah tangga yang masuk ke dalam danau dan berpontesi terjadinya eutrofikasi dan peledakan pertumbuhan tanaman air. This study aims to analyze the feasibility of the waters based on the physical, chemical and biological parameters of the waters of Paniai lake for fish farming activities. This research is a quantitative descriptive study by examining the condition of the water quality of the waters of Lake Paniai, Papua. Water samples were taken and measured at each sampling location using the composite sampling method (combined places). Lake water samples were taken at the surface and in the middle. Measurement and data collection were carried out 2 times with an interval of 1 month between measurements. The results showed that the physical parameters still show the quality standard requirements, chemical parameters, from the eight parameters measured there were 3 parameters that did not show the quality standards, namely, H2S, Nitrate and Phosphate. This shows that the high discharge of waste from the agricultural and household sectors that enters the lake has the potential for eutrophication and explosive growth of aquatic plants.

Abstract

Lipukasi Village, Barru Regency has enormous potential for marine and pond fish. Fishermen find it difficult to increase their income because they have to immediately sell their cultivation results to fish auctions with low bargaining power. The price of live fish is very low when fish are abundant, so farmers suffer losses because it is not worth the costs incurred for cultivation. The knowledge and skills of cultivating families are still low towards independent entrepreneurs, especially in increasing the added value of products and family income by diversifying food from fishery products. The characteristics of fish that are easily damaged and rotten cause farmers to have a dependence on immediately selling their cultivated products alive or fresh. This dependence can be overcome by carrying out the production process of processed food made from fish which can increase the durability and added value of products, especially fish which cannot be sold in fresh form. The development of independent entrepreneurs, especially fish processed food diversification, can increase the bargaining value and income of farming families. In an effort to increase income, the main obstacle faced by farmers and their families in conducting fish-based processed food entrepreneurship is not knowing and being skilled in processing standardized food, as well as doing fish processing and preservation business properly and in a variety according to market needs. The income of pond farmers can be increased by transferring technology, namely cultivating using biofloc, processing fish into processed fish products that are good and safe for consumption, including fish sausages, fish floss, and others. The results of this tavern are in the form of training, making biofloc, fish processing and self-employment.

Abstract

Abstrak. Desa Bubun Lamba Kecamatan Anggeraja Kabupaten Enrekang  memiliki banyak potensi yang perlu dikembangkan, antara lain terdapat kebun pertanian hultikultura yang berbukit dan kolam ikan pemancingan yang letaknya berdampingan dengan sungai yang masih dikelolah secara konvensional sehingga belum berkembang pesat dan belum menghasilkan pendapatan yang dapat mensejahterakan terhadap kelompok masyarakat yang mengelolah tempat pemancingan tersebut. Hal ini disebabkan karena keterampilan sumber daya yang dimiliki belum memadai dan modal usaha yang sangat minim serta  sistem manajemen pengelolaan bidang usaha tersebut yang belum profesional. Oleh karena itu, Program Kosabangsa yang akan dilaksanakan di Desa Bubun Lamba, bertujuan untuk meningkatkan pemberdayaan kelompok masyarakat  dalam  mengelolah tempat pemancingan yang terintegrasi dengan wisata alam agar dapat lebih berkembang dan meningkatkan pendapatan bagi kelompok mitra.  selain itu diharapkan dapat meningkatkan pengetahuan bagi mitra tentang tata cara manajemen pengelolaan suatu bidang usaha, baik dari aspek pemasaran dan promosi dengan bantuan website dan e-commerce, dan dapat mengoptimalkan fungsi kelembagaan kelompok mitra, serta membantu pemerintah setempat untuk mengurangi jumlah angka pengangguran dan dapat mendatangkan pendapatan daerah secara berkelanjutan. Kata kunci: Pemberdayaan Masyarakat, Promosi Penggunaan Digital, Peningkatan Kesejahteraan

Abstract

Penelitian ini bertujuan untuk menganalisis perbedaan aktivitas enzim protease yang terdapat pada usus benih ikan nila gesit yang dikultur dengan metode yang berbeda, menganalisis korelasi antara aktivitas enzim protease benih ikan nila gesit yang dikultur dengan metode yang berbeda. Penelitian ini dilaksanakan di UPR (Unit Pembenihan Rakyat) Ainun Maros dalam pemeliharaan dan pengambilan sampel benih ikan nila gesit dan di Analisis di Laboratorium Balai Riset Perikanan Budidaya Air Payau dan Penyuluhan Perikanan (BRPBAP) Maros untuk aktivitas enzim protease pada usus benih ikan nila gesit dan laju pertumbuhan relatif ikan nila gesit. Hubungan antara aktivitas enzim protease dengan laju pertumbuhan benih ikan nila bahwa pada minggu pertama sampai ketiga menunjukkan peningkatan aktivitas enzim setiap minggu, seiring dengan peningkatan laju pertumbuhan pada ikan Kelompok I, namun demikian besarannya masih jauh lebih kecil jika dibandingkan dengan aktivitas enzim protease dan laju pertumbuhan ikan nila gesit pada kelompok II.  Pada grafik diperoleh persamaan regresi Y = 67,289x – 2,2071 dengan R2.  Koefisien korelasi antara aktivitas enzim dan pertumbuhan sebesar 0,9984 ini berarti bahwa aktivitas enzim dan pertumbuhan memiliki tingkat hubungan yang sangat kuat.  Aktifitas enzim protease pada hari ke 7 pemeliharaan didapatkan selisih nilai sebesar 0,0077 µ/mL/Menit, pada hari ke 14 pemeliharaan didapatkan selisih 0.0193 µ/mL/Menit, pada hari ke 21 didapatkan selisih nilai sebesar 0,0173 µ/mL/Menit.  Hal ini menunjukkan bahwa tidak memperlihatkan perbedaan yang sangat nyata.  Selanjutnya berdasarkan laju aktivitas enzim protease pada kelompok I sekitar 0.0011 – 0.0019 perhari, sedangkan pada kelompok II berkisar 0.0028 – 0.0016 tidak menunjukkan perbedaan yang signifikan, sedangkan laju pertumbuhan relative benih ikan nila gesit selama penelitian pada kelompok I mengalami pertumbuhan bobot yang lebih rendah dibandingkan pada benih ikan nila gesit dan kelompok II.  Laju pertumbuhan relative pada hari ke 7 didapatkan sebesar 0.5714 % pada kelompok I dan 0.8571 % pada kelompok II. Selanjutnya pada hari ke 14 didapatkan laju pertumbuhan relative sebesar 1.1428 %, pada kelompok I dan 1.4286 % pada kelompok II.  Sementara pada hari ke 21 didapatkan laju pertumbuhan relatif sebesar 2.0000 % pada kelompok I dan 2.5714 % pada kelompok II.. This study aims to analyze the differences in the activity of protease enzymes found in the intestines of Agile Tilapia Fish cultured by different methods and analyze the correlation between the protease enzyme activity of Agile Tilapia Fish cultured by various methods. This research was carried out at the UPR (People’s Hatchery Unit) Ainun Maros in the maintenance and sampling of Agile Tilapia Fish and the Analysis at the Laboratory of the Research Center for Brackish Water Aquaculture and Fisheries Extension (BRPBAP) Maros for the activity of protease enzymes in the intestines of Agile Tilapia Fish and the relative growth rate of Agile Tilapia Fish. The relationship between the movement of the protease enzyme and the growth rate of Agile Tilapia Fish in the first to third weeks showed an increase in enzyme activity every week, along with an increase in the growth rate in group I fish. However, the magnitude was still much smaller when compared to the movement of the protease enzyme and the growth rate of Agile Tilapia Fish in Group II. On the graph obtained, the regression equation Y = 67,289x – 2,2071 with R2. This correlation coefficient between enzyme activity and growth of 0,9984 means that enzyme activity and development have an extreme degree of relationship. The activity of the protease enzyme on the 7th day of maintenance obtained a difference in the value of 0,0077 µ/mL/Minute, on the 14th day of maintenance a difference of 0.0193 µ/mL/Minute was obtained, on the 21st day a difference in the value of 0.0173 µ/mL/Minute was obtained. This shows that it does not show a very noticeable difference. Furthermore, based on the rate of activity of the protease enzyme in Group I, around 0.0011 – 0.0019 per day, while in group II the range of 0.0028 – 0.0016 did not show a significant difference, while the relative growth rate of Agile Tilapia Fish during the study in group I experienced lower weight growth than in Agile Tilapia Fish in group II. The relative growth rate on day 7 was obtained at 0.5714% in Group I and 0.8571% in Group II. Furthermore, on the 14th day, a close growth rate of 1.1428% was obtained in Group I and 1.4286% in Group II. Meanwhile, on the 21 st days, a relative growth rate of 2.0000% was obtained in Group I and 2.5714% in Group II
