Pemberian Enzim Papain Dosis Berbeda dalam Pakan Komersial pada Pemeliharaan Benih Ikan Bandeng (Chanos chanos, Forsskal)
No full textFeed is one of the problems in the milkfish (Chanos chanos, Forsskal) hatchery. The commercial feed contains protein that fish have not optimally utilized. One solution to increase protein absorption is the addition of papain enzymes. This engineering aims to analyze the application of papain enzyme in commercial feed on milkfish fry on survival, growth, feed efficiency, and RNA/DNA ratio. The test fish were milkfish fry with an average weight of 0.0003±0.0 g/head with a density of 15 fish/L. The engineering method used a completely randomized design method with 4 treatments and 3 replications. The treatments tested were administering papain enzyme in commercial feed dosages: 0.5%; 1.50%; 2.25%; and control. The engineering results showed that the administration of papain enzymes with different doses had a significant effect (P<0.05) on the relative growth rate but had no significant effect (P>0.05) on feed utilization efficiency, survival rate, and RNA/DNA ratio of milkfish fry. The highest relative growth rate value was obtained at a dose of 1.5%, which was 4.77±0.06%/day, while the lowest was found at a dose of 0.0% (control), which was 2.86±0.65%/day. The best feed efficiency value during engineering was obtained at a dose of 0.50% papain enzyme treatment of 78.0±29.3%. The highest survival rate in control was 34.6±3.70%, while the lowest was at a dose of 2.25% at 24.9±0.68%. Furthermore, the highest RNA/DNA ratio was obtained at a 1.50% papain enzyme dose of 0.85±0.14/mL, while the lowest was in control with an RNA/DNA ratio of only 0.76±0.06/mL. Water quality parameters during engineering are still within a reasonable range for milkfish fry maintenance

No full textThe North Luwu Regency Government has established a policy of developing horticultural agribusiness areas and strengthening the distance between the regional center and rural areas as producers of fruit and vegetable commodities. However, the support for the potential of natural resources is still a matter of debate between institutions. The purpose of the research was to describe the potential of eco-geographical resources and the level of importance of the institutional system in the development of horticultural agribusiness. The data that has been obtained were analyzed through two approaches, namely the data concerning the eco-geographical aspect which was analyzed through a regional complex approach. Meanwhile, data concerning social and institutional aspects were analyzed through the Interpretative Structural Modeling (ISM) approach. The results showed that all aspects of eco-geography including topography, marble level, soil type, and rainfall, were potential resources in horticultural development. Although all aspects other than the amount of funding, desperately need effective management. ISM analysis showed that horticulture development requires strategic program support, namely: (1) development of transportation facilities, (2) effectiveness of inter-institutional coordination, (3) program legitimacy and socialization, equal distribution of vision and mission of horticulture programs, (4) optimization of the role of institutions, (5) strengthening commitment between sectors, (6) increasing knowledge, and (7) developing strategic programs.
