Abstract

Fish cultivators generally experience difficulties providing quality artificial feed (pellets) due to a lack of knowledge and skills in processing technology and making alternative feeds. Besides that, the costs incurred for feed procurement are relatively large, reaching 70 - 80% of the total production costs. However, the provision of feed is often an obstacle because, in addition to the increasingly high price, the quality of available feed does not always match the nutritional needs needed by Fish. The provision of quality feed for intensively cultivated tilapia dramatically affects the resulting growth and productivity. The higher the quality of the feed, the production will also increase. One of the technologies that can be applied to overcome this problem is the manufacture of alternative formulated diets using local raw materials. The method used in this service activity is the transfer of knowledge presented in the socialization activities in the form of 1) introduction to the types of alternative fish feed ingredients sourced from the area, (2) preparation of artificial tilapia feed formulations, (3) manufacturing technology artificial feed (pellets) and 4) monitoring and assistance. The socialization was carried out in the form of a lecture and was followed by a question and answer session. The results of farmer activities recognize the types of local feed that can be used as fish feed, know the preparation of feed formulations, and alternative artificial feed manufacturing technologies. The knowledge and skills possessed by fish cultivators are expected to overcome the difficulties of fish farmers in providing feed so that fish production and cultivation business increase.

Abstract

Perubahaan tata guna lahan merupakan sesuatu yang pasti terjadi sebagai akibat adanya pertambahan penduduk dan perkembangan ekonomi. Namun perubahan tata guna lahan sering kali mengabaikan respon hidrologi sebagai akibat pertambahan penduduk. Adanya banjir di tahun 2016 mengindikasikan adanya permasalahan dalam tata guna lahan pada DAS Air Dingin. Berpijak pada permasalahan tersebut penelitian ini memiliki tujuan untuk: (a) menganalisa pengaruh perubahaan penggunaan lahan terhadap respon hidrologi di DAS Air Dingin, dan (b) menentukan pengelolaan lahan optimal sehingga mengurangi laju aliran permukaan yang terjadi di DAS Air Dingin. Menggunakan model HEC-HMS dan metode Curve Number – Soil Conservation Service (CN-SCS) dalam merumuskan skenario penggunaan lahan sehingga aliran permukaan di DAS Air Dingin dapat digambarkan dalam bentuk hidrograf. Nilai CN-SCS divalidasi menggunakan metode Nash-Sutclife dengan nilai efisiensi (E) 0,75 yang berarti model memiliki akurasi tinggi dan dapat diterapkan. Hasil simulasi terhadap skenario 1 menghasilkan debit puncak 497 m3/s lebih kecil jika dibandingkan debit puncak lahan existing 502,4 m3/s.
