Abstract

Currently, in planning for mineral and coal exploration drilling, there are still many questions about how to determine the optimal borehole distance for resource classification, because the determination of the number of drill holes will be highly correlated with the expenditure of exploration funds. The solution to answer these questions is to increase the knowledge and understanding of exploration planners regarding borehole distance analysis for resource classification, especially by using geostatistical methods. In this case, the technique used is global estimation variance. The implementation of community service in the form of workshops is carried out in various stages, including the planning stage, workshops and activity evaluation. The results of this activity can increase the understanding and knowledge of the participants about the concept of geostatistics and determining the optimal number of drill holes. The conclusion of the workshop that was carried out was that almost all participants were able to receive the material presented, it was seen from the very intensive discussion at the end of the event and at the end of the event the participants wanted further training by increasing practice.

Abstract

All human activities inevitably produce waste. The amount of waste increases as the city grows. Sukmajaya District, Depok City is one of the districts that has the potential for very high waste accumulation. This area is a place for immigrants who work in Jakarta. This has a negative impact, namely the increase in the number of Final Disposal Sites (TPA) from year to year. The recycling process is a solution that can save energy and reduce landfill waste. The use of can waste as raw material in making alum or potassium aluminate sulfate K[Al(SO4)2.12H2O] is very relevant. The basic material used in making alum cans has the advantage of being more economical and can help reduce packaging can waste which has the potential to pollute the environment. The team held training in making alum minerals from used can waste in Sukmajaya District, Depok City. This activity aims to educate the public in utilizing used can waste into alum mineral products. People can use it to purify water in an environmentally friendly and economical way. The results of the training activities showed an increase in participants' awareness and skills in managing canned waste into value-added products. The number of training participants increased from 40% before training to 90% after training. Apart from that, participants' skills in making alum from used can waste also increased from 25% before the training to 85% after the training. It is hoped that this training can make a positive contribution in efforts to manage waste sustainably and protect the environment.

Abstract

The Trisakti University Community Service Program (PKM) was carried out in Cisarua Village, Nanggung District, Bogor Regency, West Java, in collaboration with the local Regional Government. Stakeholder partners served as facilitators for this project, which aimed to socialize and establish sustainable mining practices for miners and communities around gold mines. Cisarua Village, located in Nanggung Regency, is known for having potential mineral resources, particularly gold deposits, which are often collected by mining communities both individually and collectively. However, this mining activity has major negative effects, leading the government to stop it, one of which being its damaging environmental impact. Environmental issues and land conditions following gold mining provide significant risks and concerns, including mercury and cyanide contamination, which are harmful to human life and the surrounding environment. One of the most significant issues has been the lack of reclamation of mine holes caused by human mining activity. Based on these issues, the team demonstrated the public on good and correct mining practices (GMP). The team is collaborating with local communities and governments to develop ways to predict future implications of gold mining activities. PKM activities are carried out by offering materials and discussions that have proven effective in developing community knowledge. The survey of 25 respondents showed that a greater understanding of good mining practices. Survey results show that previously 61% of respondents did not understand about GMP. After implementing education and training through PKM, there was an increase of 11% in understanding of GMP. This shows the effectiveness of the program in increasing awareness and knowledge about good and correct mining practices among participants.
