Cookies are one of the snacks made from wheat flour and other ingredients like sugar, butter, eggs, flavors, and others. Cookies are usually found in certain festive days used as food treats to guests, but now cookies become a daily snack. The development of cookies is currently widely carried out, especially in replacing wheat flour raw materials with flour that has higher nutritional value such as coconut pulp flour and eggshell flour. The purpose of this study was to determine the effect of adding coconut pulp flour in substituting wheat flour and adding eggshell flour on the chemical and organoleptic properties of cookies and to determine what proportion of coconut pulp flour in substituting wheat flour and adding the best eggshell flour in making cookies. This study used a Complete Randomized Design (CRD) with one factors, namely wheat flour: coconut pulp flour: eggshell flour with 4 treatments P1 = 10%:80%:10 %, P2 = 15% :70%:15% , P3= 20%:60%:20%, P4 =25%:50%:25%. P4 treatment is the best treatment, with the concentration of wheat flour 25%, coconut pulp flour 50%, and eggshell flour 25%, with the highest yield value of 0,80888. The variable criteria for P4 treatment are calcium content = 14.49 mg , fiber content = 5,03%, water content = 3.53%, taste = 4 (like), texture = 4 (like), aroma = 4 (like), and color = 4 (like).

Brownie chips are a popular snack, but they are generally made from wheat flour which contains gluten. Gluten in food causes celiac disease, etc. Alternatives to the use of wheat flour in food have not been widely used. The use of jali - jali as a local cereal with high fiber content as an ingredient for brownie chips has not been widely practiced. Apple cider drink is a processed beverage product made from apples and is usually processed on a large or small industrial scale. Processing apple juice produces a very high amount of apple pulp waste, but unfortunately the use of apple pulp waste is still limited to only being used as a substitute for fertilizer, animal feed and some of it is just thrown away. Apple juice pulp has a high fiber content so it has the potential to be used as an additional ingredient in food production. This research aims to determine the effect of the best proportion of apple juice pulp and jali - jali flour (Coix lacyma - jobi L.) on the chemical and organoleptic quality of making good brownie chips and to determine the best proportion of apple juice pulp and jali - jali flour ( Coix lacyma - jobi L.) resulting in good chemical and organoleptic properties in making brownie chips. This research used a Completely Randomized Design (CRD) with 1 (one) factor, namely the proportion of apple pulp and jali - jali flour (Coix lacyma - jobi L.) which consisted of 4 levels of treatment, namely: level 1 (60%: 40%), level 2 (50%: 50%), level 3 (40%: 60%), level 4 (30%: 70%) with 3 repetitions. The best treatment for making brownie chips is in treatment P2, namely a concentration of 50% apple plup and 50% jali - jali flour with the highest total value of 0.482. The criteria for the P2 treatment variable are water content = 9.21, fiber content = 1.6, vitamin C content = 24.54, taste = 3.7, texture = 3.6, aroma = 3.9, and color = 3.9.

Betta fish is a type of freshwater ornamental fish that has many unique characteristics. The aim of this research was to determine the type of natural feeding that had the best effect on the absolute weight growth of Betta fish (Betta splendes) aged 1 month. The experimental design used in this research was a Completely Randomized Design (CRD) with three treatments and nine replications. The treatments in this research were the provision of various types of natural food, treatment A (Mosquito Larvae), treatment B (Silk Worms) and treatment C (Water Fleas). The three types of natural food are given to Betta fish (Betta splendes) at the same dose of 15% of their body weight. The variable measured was the absolute weight growth of Betta fish (Betta splendes) aged 1 month. The results of the study showed that treatment B with the provision of natural silk worms (Tubifex Sp) resulted in the highest absolute weight growth of 1 month old Betta fish (Betta splendes) of 2.13 gr/head. Meanwhile, treatments A and C experienced a decrease of 1.63 gr/head and 1.41 gr/head respectively. Water quality parameters include acidity between 7.3 - 7.8, water temperature between 27.2°C - 27.9°C, and dissolved oxygen between 5.2 - 5.7 ppm.
