Abstract

ABSTRACTThe purpose of this research was to evaluate the implementation of the mining safety management system (SMKP) and the mining environmental protection management system (SPPLHP), analyze employee perceptions of the system, and analyze priority strategies for system improvement at PT. Sumber Energi Jaya. (SEJ). This research was conducted from October to December 2020. The research method used is a survey method with questionnaires, interviews, observations, and documentation. Determination of the sample in this study using the purposive sampling method with 50 employees as respondents. The perception data was obtained by using a questionnaire and then tested for validity and reliability with the SPSS 26 program and measured using a Likert scale. The strategy analysis used is SWOT analysis and AHP analysis with the Expert Choice program version 11. The results show that the implementation of SMKP 72% and SPPLHP 80% can be categorized as achievement at the proactive level and measurement of employee perceptions of SMKP and SPPLHP is categorized as high. The priority strategy of SMKP is to optimize company support by allocating a budget for system improvement and SPPLHP's priority strategy is to optimize the management of the mining environment by integrating information, planning, programs, budgets, procedures and structures.

Abstract

This study aims to analyze the density and net calorific value and analyze the traditional market waste leachate. The sampling locations were in traditional markets in 5 districts/cities, namely Manado City, Bitung City, North Minahasa Regency, Minahasa Regency, and Tomohon City. This research was conducted in May – August 2021. The method used in this study is a quantitative descriptive survey research method and tabulated analysis equipped with a histogram graph. Visiting and observing at the research site then combining it with primary and secondary data. Primary data in the form of waste samples to be observed and secondary data in the form of information or supporting documents from related parties. The parameters observed were the density of traditional market waste, calculating the Net Calorific Value of each waste sample, and analysis of pH, TDS, TSS, EC in traditional market waste leachate. The conclusion of this study is that organic waste shows the highest density value in 5 regencies/cities and the average net calorific value of 5 regencies/cities ranges from 7000 kcal/kg – 8000 kcal/kg and the presence of leachate in traditional market waste shows high TDS value. Likewise, the EC value indicates the presence of cation ions in the leachate. The presence of leachate is intended not as a pollutant component but as an indicator that can provide nutrients for plant growth.
