Abstract

This research discusses the implementation of agroforestry patterns in Aik Bual Community Forest, Central Lombok, which is managed by 260 farmers on 94.45 hectares of land with a 35-year management licence from the Ministry of Environment and Forestry. Agroforestry, which combines agricultural and forestry crops, is focused on maximising productivity and maintaining environmental sustainability. The research was conducted from February to June 2024 with a descriptive method, involving interviews, field observations, documentation and literature studies. Analyses showed that agroforestry patterns increase vegetation diversity and plant structure. Further research is needed to understand the interaction between agroforestry patterns and plant diversity in Aik Bual HKm. The results of this study are expected to support sustainable forest management and provide ecological and economic benefits to the surrounding community.

Abstract

In the midst of demands to reduce dependence on fossil energy sources that are decreasing, this research was conducted as an effort to make bioethanol as an alternative energy source. The purpose of this study was to determine the effect of yeast variation on pH and bioethanol content. This research was conducted using the method of Completely Randomised Design (CRD) factorial pattern involving one main factor, namely yeast variation with three replicates for each treatment. Parameters in this study are pH testing and bioethanol content. The best results of both peremeter is the best pH contained in the 3rd treatment with an average amount of 4.84, in testing the bioethanol content of the best value contained in the 3rd treatment with the amount of yeast 6 grams of ethanol content average 0.9%. It can be concluded that bioethanol content is influenced by yeast, distillation, and fermentation time. the higher the yeast, the higher the pH, alcohol density, and yield produced.

Abstract

Abstract: Biogas is a renewable energy source. Biogas can be produced from agricultural waste and industrial waste. One of the alternatives to handling tofu industry waste that currently has a lot to be developed is to convert industrial waste into alternative fuel in the form of biogas. This study aims to determine the effect of the addition of tofu liquid waste on changes in temperature, pH, volume and pressure that occur during the formation of biogas. This research was conducted from July to August for 22 days. The method used in this research is the experimental method by conducting direct experiments. The design used in this study was a one-factor Completely Randomised Design (CRD), consisting of P0 with rice straw + 4 litres of water, P1 with the addition of 20% tofu liquid waste, P2 with 40%, P3 with 60%, P4 with 80% and P5 with 100%. Observation data were analysed with Analysis of Variance at the 5% level. The parameters observed in the study were temperature, pH, volume and pressure. Based on the results of the analysis that has been done, the lowest temperature was obtained in the P3 treatment at 27.39 ° C, while the highest temperature was obtained in the P2 treatment at 27.86 ° C. The lowest pH was obtained in the P5 treatment at 4.24, while the highest pH was obtained in the P1 treatment at 4.57. The lowest volume was obtained in the P1 treatment at 0.00000011513 m3, while the highest volume was obtained in the P0 treatment at 0.00000161291m3, the lowest pressure was obtained in the P3 treatment at 109.08 N/m2, while the highest pressure was obtained in the P2 treatment at 109.25 N/m2. Therefore, it can be concluded that the addition of tofu waste to rice straw does not significantly affect the formation of biogas produced.

Abstract

Simple Drip Irrigation is automatic and cheap plant watering. Simple Drip Irrigation is a plant watering technique that uses a water reservoir or water reservoir can be a used bottle that is given a channel to drip the planting media little by little constantly, so that the planting media remains fulfilled its water needs, without becoming muddy and the water supply remains sufficient. This study aims to determine the water efficiency by using drip irrigation method on the growth of lettuce plants. The method used in this research is an experimental method using a Randomised Group Design (RAK) consisting of 3 treatments, namely 3 replications so as to obtain 12 experimental units, first P1 = 300ml water application, second P2 = 200ml water application, and P3 = 100ml water application and analysed using analysis of variance (Anova) at a real level of 5% and if there is a treatment that has a real effect then a test is carried out using the honest real difference test (BNJ) at a real level of 5%. The results of field research conducted by researchers that the provision of drip irrigation has no significant effect on the parameters of plant height, dry trimmed weight, stem diameter, soil texture but significantly different on wet trimmed weight and for the best treatment obtained in the P2 treatment which produces the highest wet trimmed weight of 93 grams.

Abstract

One of the materials that can be used to make activated charcoal is bidara wood. Bidara wood has a high carbon content and a good pore structure. In addition, bidara wood also contains several minerals such as calcium, potassium, and magnesium in small amounts. The content of these compounds and elements makes bidara wood very suitable to be used as a raw material for activated charcoal. One of the activation materials is an H3PO4 solution. In the activation process, bidara wood activated charcoal can improve its quality properties, such as surface area, pore volume, and adsorption capacity. Therefore, the aim of this research is to determine the effect of heating temperature variations on the quality properties of bidara wood activated charcoal using chemical activation with an H3PO4 solution. The experimental design used in this study is a Completely Randomized Design with one factor, which is the activation temperature (500, 600, and 700˚C). The results of the study showed that the use of H3PO4 solution at a temperature variation of 700˚C resulted in better properties for moisture content (5.41%), ash content (43.29%), and iodine adsorption capacity (4,737 mg/g) compared to the temperature variations of 500˚C and 600˚C.
