Abstract

Palm shell waste and empty palm fruit bunches thrown away can cause environmental pollution. This palm oil waste can be used as an environmentally friendly energy source, namely briquettes. Briquettes, as an environmentally friendly energy source, can be used as teaching material in school science learning. This study aims to design learning units for environmentally friendly energy sources based on palm shell waste briquettes and empty palm fruit bunches as teaching materials. Data collection techniques were carried out by observing the potential of palm oil waste in the North Bengkulu area and need analysis, including material analysis and interviews. The resulting analytical data were analyzed descriptively regarding the composition, texture, colour, test of briquettes used, burning time, calorific value and moisture content of the resulting briquettes. The sample of needs analysis data collection was determined by purposive sampling. The data from the analysis will be developed into teaching materials packaged in designing learning units on environmentally friendly technology materials for junior high school students

Abstract

This research aims to determine the optimal composition and fermentation time by varying the starter used to make bioethanol. The method used was an experiment with 45 samples of yellow kepok banana peel which were fermented for 13, 19 and 25 days. This research used 5 treatments, namely, a) composition A, namely 100% yeast (no added nutrients); b) composition B, namely 100% urea; c) composition C, namely 100% NPK; d) composition D, namely 50% urea and 50% NPK; e) composition E, namely 75% urea and 25% NPK. The quantitative data obtained was then analyzed using the average bioethanol content presented in the table. Qualitative data was analyzed descriptively with a systematic study. The results showed that the highest bioethanol content was obtained after fermentation (12.67 ± 9.29%) and after distillation (32 ± 10%) with composition A (100% yeast) and a fermentation time of 25 days. The highest combination of bioethanol yields was obtained after fermentation (6 ± 0%) and after distillation (31.67 ± 2.31%) with composition E (75% urea and 25% NPK) with a fermentation time of 25 days. In conclusion, the longer the fermentation time, the more bioethanol content increases. Keywords: Bioethanol, Kepok Banana Peel, Environmentally Friendly Technology

Abstract

This research was carried out from November to December 2023, at the Ruyani Life Sciences Learning Resources (SBIH). The aim of this research was to determine the effect of feeding tofu dregs and cow dung on the growth of earthworms (Lumbricus rubellus). The method used in this research was an experimental method, namely a Completely Randomized Design (CRD) with 6 feed treatments + 3 repetitions for continuation of undergraduate student research and 6 feed treatments + 3 repetitions for initiation. Data analysis used the Kruskall-Wallis nonparametric statistical test with Asymp. Sig. values. ≤ 0.05, and continued with the Mann-Whitney test. The research results show that the value of Asymp. Sig. parent biomass, offspring biomass, number of parent individuals, and number of Lumbricus rubellus offspring in sequence, in the 1st to 4th week of follow-up research Asymp. Sig. values. namely 0.086; 0.036; 0.140; and 0.064. In the 5th to 8th week of further research, the Asymp. Sig. value. namely 0.168; 0.047; 0.176; and 0.095. And in the 5th to 8th weeks of the research, the Asymp. Sig. value was initiated. namely 0.062; 0.010; 0.434; and 0.013. The conclusion was that feeding tofu dregs and cow dung had no real effect on parent biomass and number of parent individuals, and there was a real difference in offspring biomass and number of Lumbricus rubellus offspring in the initial study.

Abstract

Bioethanol is an energy source obtained through fermentation. In bioethanol production, Persea americana seeds are used as a fermentation medium because they contain lots of carbohydrates. This research aims to determine the effect of additional nutrients (NPK and urea fertilizer) required by Saccharomyces cerevisiae by varying the nutritional variables in the form of NPK and urea fertilizer. The process of making bioethanol goes through stages: making Persea americana seed flour, hydrolysis process using 6% HCl, then fermentation process, and distillation process. This research was carried out with the addition of Nutrients in the form of NPK and Urea Fertilizer with 5 treatments, namely: A) 100% yeast (no addition of Nutrients); B) 100% NPK (4 g); C) 100% Urea Fertilizer (4 g); D) 50% NPK and 50% Urea Fertilizer (4 g NPK and 4 g Urea Fertilizer); and E) 75% NPK and 25% Urea Fertilizer (3 g NPK and 1 g Urea Fertilizer), and varying the length of fermentation time to 13, 19, and 25 days. Success parameters are assessed through the bioethanol yield produced by each treatment. The research results showed that the highest bioethanol (29.7 ± 0.47%) was composition E (NPK 75% and Urea Fertilizer 25%) with a fermentation time of 25 days.
