Abstract

Meatballs are one of the processed food products made from meat and have a fairly high composition of protein, minerals, and vitamins. Red spinach (Amaranthus Tricolor) is one of the vegetables that is less popular among the public. Red spinach contains high antioxidants. This study aims to determine the amount and effect of adding red spinach leaf extract on the quality of chicken meatballs produced. The experimental design used in this study was a complete randomized design (RAL) with a red spinach extract concentration factor consisting of 4 treatment levels, namely A = 0%, B = 10%, C = 30%, D = 50%. Each treatment was carried out 5 times so that 20 experimental units were obtained. The results showed that the addition of red spinach leaf extract with different concentrations of 0%, 10%, 20%, and 50% had a significant effect on the color, taste, aroma, and texture of the resulting chicken meatballs. The best treatment obtained is treatment B where the concentration of adding spinach leaf extract as much as 10% to chicken meatballs according to sensory analysis

Abstract

Koi fish is a type of ornamental fish whose color and unique body shape are one of the attractions of koi fish. This study aims to determine and evaluate the effect of fasting time on the growth and survival of koi fish (Cyprinus carpio) which are fasted periodically at optimum temperature. The method used in this study was the RAL experimental method (completely randomized design) with 4 treatments and 3 replications. The fasting treatment used was the non-fasting treatment as (control), 1 day of fasting and 1 day of feeding, 1 day of fasting and 2 days of feeding, and 1 day of fasting and 3 days of feeding. Each treatment used seeds measuring 4-5 cm. Parameters observed were absolute weight growth, absolute length growth, daily growth rate, survival rate and feed conversion ratio. The results of the study based on the analysis of variance showed that fasting in koi fish had a significant effect (P<0.05) on absolute weight growth and daily growth rate and had no significant effect on growth in absolute length, survival raet and feed conversion ratio. The best treatment of periodic fasting is in treatment P2 = 1 day of fasting 1 day of being feed.

Abstract

The hatchery is a biosecurity system in the form of a water quality control system and aquatic environmental health. Hatchery determines the success or failure of spawning. Temperature, pH and dissolved oxygen are key water quality parameters that control the distribution and distribution of organisms in the waters. Temperature, pH and dissolved oxygen in waters are key water quality parameters that control the distribution and distribution of organisms in the waters. This study aims to describe fluctuations in water quality, namely temperature, pH, and DO in the indoor hatchery based on different times. The design used was a RAL with 3 treatments and 4 repetitions, namely P1: observing water parameters every 1 hour (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 WIT); P2: observation of water parameters every 2 hours (6, 8, 10, 12, 14, 16, 18, 20, 22, 24 WIT); and P3: observation of water parameters every 4 hours (6, 10, 14.18, 22 WIB). The results showed that in general the temperature, DO and pH values ​​in the indoor hatchery did not fluctuate significantly. However, during the observation at 14 to 16 WIB at P1 there was an increase in temperature and DO, on the contrary there was a decrease in the pH value. When DO increases, the pH appears to decrease. At P2 there was a decrease in temperature values ​​at 6 to 8 WIB, while the DO and pH values ​​were stable. Furthermore, at P3, it can be seen that the temperature, DO and pH values ​​are more stable.

Abstract

Milkfish is a leading commodity for Indonesian mariculture which is quite promising, so milkfish productivity must be increased. The problematic factor in cultivating milkfish is feed. Lamtoro leaves (Leucaena leucocephala) are a potential biological resource and have high protein content as a raw material for making feed. However, lamtoro has a high fiber content which can be reduced by fermenting using bio intan tani and attractants to cover the aroma of lamtoro which fish do not like. This research aims to test the effect of adding fermented lamtoro leaves to artificial feed on the growth of milkfish. The research was carried out on March 22 - April 22 2022 at Kembang Tani Farm Lancang Barat, North Aceh, Aceh. The research used a non-factorial Completely Randomized Design (CRD) consisting of 4 treatments and 3 replications, Treatments A, B, C and D with concentrations of 0%, 15%, 20% and 25% respectively. Based on the F test analysis (ANOVA), the results gave a significant effect on feed response, weight gain, length increase, aroma with a Sig value < 0.05 and gave results that had no real effect on survival rate and feed conversion value with a Sig value > 0. 05.
