There is a lot of uncertainty in farming, such as farming funds using the results of previous agriculture; if it is not sufficient, farmers will make loans or use their assets. The long cassava production process, one year, only produced once, so for business sustainability, this cassava farming needs to be studied further. This study will see how the use, fulfillment, and factors affect the need for funds in cassava farming in South Abung District. The research location was determined purposively, and 153 farmers were selected using purposive random sampling. The analysis used is descriptive and Multiple Linear Regression. This study indicates four sources of funding for cassava farming: sources from own funds, loans to relatives and friends, intermediaries, and KUR. The funds owned by cassava farmers are allocated to buy seeds, fertilizers, pesticides, pay for labor, land taxes, and equipment depreciation. The factors that significantly influence the need for funds for cassava farming at the 95% confidence level are land area, seeds, fertilizers, and labor.

Catfish is the primary commodity of freshwater consumption fish that is widely cultivated with a high protein content of 68.6% and a high selling price. In addition, catfish meat is believed to be capable of preventing heart and cardiovascular disease because its unsaturated fats. Catfish skin can be used as a source of collagen in the culinary, cosmetic, and health fields. Catfish spawn all year round because of the abundance of food. The environment can help stimulate the synthesis of reproductive hormones in the reproductive activity of catfish. Environmental manipulations such as temperature, pH and salinity have different effects on the hatchability of catfish (Pangasius sp.) eggs. High temperatures can speed up the hatching time of the eggs but drop the hatching percentage and survival rate because high temperature activates the chorionase enzyme containing pseudokeratin which softens fish egg shells. In contrast to the pH treatment, a pH that is too acidic will deactivate the work of the chorionase enzyme so that the shells of fish eggs are difficult to break, resulting in a low percentage of hatching and survival rate with the longest hatching time. Salinity works by balancing the osmoregulatory pressure in the shell with the environment. A high salinity concentration can damage the egg by breaking into and swelling the eggshell, causing a low survival rate. On the other hand, eggs not treated with salinity were reported to have the lowest hatching percentage due to fungi attacking the eggs causing embryos to die. Salinity does not affect egg hatching time.

The dependence on the use of wheat flour in the manufacture of bakery products should be reduced to reduce wheat imports. One alternative that can be done is substituting wheat flour with other flour, for example, banana flour. In their manufacture, cookies substituted for banana flour produce a brown color that is not preferred. Therefore, to fix this, in making cookies, the addition of green moringa leaf flour is carried out. Besides being expected to improve the cookies' color, Moringa leaf flour also contains good nutrients. Moringa leaf flour contains protein, minerals, vitamins, essential amino acids, and antioxidants. The nutrients contained in moringa leaf flour have the potential to be nutritious food additives and beneficial to health. The purpose of this study was to determine the effect of the addition of moringa leaf flour on wheat flour cookies and banana flour on physical characteristics (moisture content, color, and texture), chemical characteristics (protein content and ash content), and organoleptic (color, aroma, taste, texture, and overalls). This study used a complete randomized design (CRD) with 1 factor: the percentage of addition of Moringa leaf flour, 0%, 2.5%, 5%, 7.5%, and 10%. Adding Moringa leaves to manufacture cookies from wheat flour and banana flour significantly affects the moisture content, texture, color, protein content, and ash content of the cookies produced. The most preferred cookies are cookies with the addition of 5% moringa leaf flour.
