Abstract

This study aims to: (1) Analyze the effect of artificial eco enzyme addition on improving the quality of dug well water based on pH, TDS, TSS, and DO parameters; (2) Analyze the effect of artificial eco enzyme addition on reducing ammonia and metal content in dug well water. The type of research is a laboratory-scale experiment with a quantitative approach to dug well water samples treated using a complete randomized design (CRD). The characteristics of the experimental test are 4 times treatment 1 time repetition in a homogeneous sample population. The conclusion of the research is that the provision of artificial eco enzyme has an effect in the form of an average increase and decrease in each parameter of the water quality of the dug well, namely pH 0,4, TDS 22 mg/l, TSS 13,3 mg/l, DO 4,2 mg/l, NH3 2,5 mg/l, Fe 0,4 mg/l, and Mn 0,03 mg/l. Based on one-way ANOVA testing resulted in sig. 0.001 0.05 and Duncan testing resulted in different number notations in each sample with sig. 1.000 0.05 which means the addition of eco enzyme gives a real influence on improving the quality of well water.

Abstract

This study aims to determine the growth and yield of sweet corn based on the concentration of phytohormones sprayed day and night. As well as to find out which concentration of phytohormones gives the best effect on the parameters of plant height, number of leaves, age of flowering, fruit weight, and number of fruit. This study used a two-factor completely randomized design (CRD). The first factor of phytohormone concentrations consisted of T0 = 0 ml/L, T1 = 6 ml/L, T2 = 8 ml/L, T3 = 10 ml/L, T4 = 12 ml/L with 3 repetitions and 27 experimental units. The subject of this research is phytohormone and the object of this research is sweet corn of bonanza F1 variety. Collecting data in this study is by direct observation and documentation. Data were analyzed by ANOVA (Analysis of Variance) followed by the DMRT test if there was an effect. Based on the results of the DMRT test, treatment T4 = 12 ml/L had an effect on plant height and fruit weight with values of 195.4 cm and 162 grams, respectively. Treatment T3 = 10 ml/L had an effect on the number of leaves with a value of 18.7 and treatment T1 = 6 ml/L had an effect on the age of flowering with a value of 46.2 HST. The best phytohormone administration is produced from the administration of phytohormone which is sprayed during the day.

Abstract

The production of alternative feeds as a substitute for commercial feeds is expected to reduce the cost of farmers, with fermentation techniques to improve feed nutrition so that it is better and more durable by utilizing rice bran. This study aims to find out the right dose of feed and find out the effect of feeding on the growth of koi fish seeds. The methods used are experimental and observation techniques. Data analysis techniques use SPSS. The results of the study on fish weight produced normally distributed data, homogeneous and there was also a real difference, namely in the treatment A, B, C and K can be seen the best treatment, namely in B (100% fermented rice bran feed). While the results of the study on the length of the fish produced normally distributed data, homogeneous and there was an influence, there was also a real difference, namely the best treatment, namely in B (100% fermented rice bran feed) with the best dose of 0.08gr. Based on the statement above, the fermentation of rice bran affects the growth of koi fish seed cultivation.
