Abstract

The purpose of this study was to determine how illegal rock mineral mining in Kota Donok Village, Lebong Regency, impacts the environment. The location of the study was Kota Donok Village in South Lebong District, Lebong Regency, and the type of research was descriptive qualitative. The community living in the mining environment of CV. Jang Riang in Kota Donok Village, South Lebong District, Lebong Regency, was the subject of the study. Furthermore, there were 6 parties responsible for environmental management of the rock mineral mining process in Lebong Regency, including CV. Jang Riang, the Head of Kota Donok Village, and the Energy and Mineral Resources (ESDM) Service of Bengkulu Province. Therefore, the total subjects were 34 people. Data collection was carried out through questionnaires, and data analysis was carried out through descriptive and SWOT analysis. The results of the study showed that illegal mining in Kota Donok Village, Lebong Regency had a very damaging environmental effect, damaging the local ecosystem and the social and economic aspects of the surrounding community. The biggest threats to environmental sustainability and human welfare in the area are aesthetic impacts, water pollution, and loss of ecological function. The management instructions for illegal rock mineral mining activities in Kota Donok Village, Lebong Regency are a defense strategy that aims to stop the rate of damage and reduce further risks by increasing supervision, conducting environmental mitigation, and encouraging the community to actively participate in environmental conservation. This method can be used to control, overcome, and repair the impacts of illegal mining

Abstract

Sakura Block Plus is a modification of Sakura Block, incorporating 6% earthworms and palm kernel cake as substitutes for corn. The objective of this study was to evaluate the supplementation of Sakura Block Plus in palm frond feed on the nutrient digestibility of beef cattle. The research design employed a Latin Square Design (LSD) with treatments P0 (10% Sakura Block Plus), P1 (8% Sakura Block Plus), P2 (10% Sakura Block Plus), and P3 (12% Sakura Block Plus).  Four male beef cattle, 18 months old, weighing approximately ± 110 kg, were utilized throughout four treatment periods, each lasting 15 days. The results of the study indicated a significant improvement in the 12% Sakura Block Plus treatment concerning the digestibility of Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), and hemicellulose. In conclusion, the supplementation of Sakura Block Plus at the 12% level in palm frond feed resulted in the most optimal nutrient digestibility.

Abstract

This experiment aimed to compare palm kernel meal and soybean meal as sources of rumen undegradable protein for kacang goats. Sixteen 10-month-old doeling weighing between 13-14 kg were used as experimental animals. A completely randomized design was applied to test four types of feed treatments, namely setaria grass-based feed and different cube-shaped concentrate feed (CCF), with four replications for each treatment. The four types of treatments were: P1. CCF without soybean meal, P2. CCF with soybean meal without heating, P3. CFF with soybean meal heated at 165oC for 75 minutes, and P4. CCF with soybean meal heated at 165 oC for 150 minutes. Each treatment was given a ration consisting of 50% Setaria grass as a basal feed and 50% CCF according to the treatment (on a dry matter basis). The variables observed were dry matter and nutrient intake, dry matter and nutrient digestibility, and average daily weight gain for 12 weeks. The data obtained were analyzed using analysis of variance (ANOVA) using the Systat for Windows statistical software package, if there were differences, further testing was carried out using the least significant difference (LSD) test. The results showed that nutrient intake was not significantly different (P>0.05), but the lowest digestibility value (P<0.05) was in treatment 4, CCF which used soybean meal with longer heating. The highest daily weight gain (P<0.05) was achieved by goats that received PKK palm kernel meal. It was concluded that the use of palm kernel cake in CCF gave good results, as indicated by the highest average daily gain of goat
