Abstract

This research aims to determine differences in growth and calcium levels of lettuce plants ( Lactuca sativa L.) after applying liquid organic fertilizer from rice straw and tea dregs. This research used an experimental method with a Completely Randomized Design (CRD) with 3 replications and two factors, namely the dose of liquid organic fertilizer (P1 = 10 ml and P2 = 13 ml) and the time of application of liquid organic fertilizer (W1 = once every 5 days and W2 = every 7 days). The results of the research showed that all treatments had different effects on the growth and levels of lettuce plants. The treatment that has the most influence on the growth and calcium levels of lettuce plants is P2W2 (13 ml fertilizer dose and application time every 7 days). Keywords: Tea dregs, rice straw, calcium, lettuce plants, liquid organic fertilizer

Abstract

This research aims to determine the bioecological aspects of Betta fusca as teaching material for the Ecology Course. The research method used is an exploratory method. The research results showed that the length-weight relationship of Betta fusca fish showed negative allometric results, which means that the increase in length of the fish was not proportional to the increase in weight. The male to female sex ratio was found to be 1:2, indicating the predominance of females over males in the observed population. The physical and chemical parameters of the water observed showed variations, but everything was still in optimum conditions to support the life of Betta fusca. The conclusion of this research is that the bioecological conditions of Betta fusca in Labuhanbatu Raya Regency still support the sustainability of the population of this species. Keywords: Betta fusca, Bioecology, Animal Ecology

Abstract

The aim of this research is the isolation and identification based on the morphological characteristics of lactic acid bacteria in the fermentation of organic waste from fruit peels. Isolation of Lactic Acid Bacteria was carried out using the spread plate method on de Man, Rogosa, and Sharpe Agar (MRSA) media. The culture was incubated at 37 °C for 48 hours. The growing colonies were observed for morphological characteristics, and bacterial Gram staining was carried out. The results of the research showed that 10 bacterial isolates were obtained from the isolation of BAL from ecoenzymes on de Man, Ragosa, and Sharpe Agar (MRSA) media, namely E-BAL 01, E-BAL 02, E-BAL O3, E-BAL 04, E-BAL 05, E-BAL 06, E-BAL 07, E-BAL 08, E-BAL 09, and E-BAL 10, and 10 isolates were characterized as Gram-positive with a bacillary cell form. In conclusion, 10 isolates were found with characteristics that supported MRSA media, namely isolates of lactic acid bacteria of the genus Lactobacillus. This is confirmed by the results of biochemical tests, namely that it is immobile, does not produce the catalase enzyme, and does not have the ability to produce gas.

Abstract

The research aims to determine the effectiveness of the growth and phosphorus (P) content of green mustard plants (Brassica juncea L.) after administering POC from rice straw waste and banana stems at different time intervals and doses. The research method used was an experiment with a Completely Randomized Design (CRD) type of two factors, including the dose of liquid organic fertilizer (D1 = 10 ml and D2 = 13 ml) and the time interval for fertilizer application (I1 = once 5 days and I2 = once 7 days) and 3 repetitions. The results were analyzed using a two-way ANOVA with a significance level of 0.05. The results showed that the treatment given had a significant effect on the growth of plant height, wet weight, root length, and phosphorus content but had no significant effect on the growth of the number of leaves. I1D1 treatment (5 day interval, dose of 10 ml) is the best treatment for plant growth and phosphorus content of green mustard greens (Brassica junea L.).
