Abstract

Mineral resources, coal, and rock are one of the potentials possessed by Indonesia to be able to earn income from the mining sector. West Bandung Regency is one of the areas that have quite a lot of potential rock and mineral resources. The potential of this area is quite large, namely andesite rock, sand, limestone, and sandstone. Zeolite and others. On the other hand, the West Bandung area has a high potential and threat of being a disaster-prone. West Bandung Regency has the highest number of natural disasters occurring in the type of landslide disaster, which occurred 52 times in the period 2008-2016, or 68% of all disasters. Loss of economic value also occurs for mining material resources which are limited by the existence of a disaster zone. So it is necessary to carry out mitigation from the start to map disaster areas that have an impact on the distribution and existence of mining material resources. This study aims to identify and analyze the potential of rock resources in disaster-prone areas, so as to be able to prioritize conservation aspects for potential mining materials. The method used in this research is through literature study, mapping the potential of mining materials, mapping the potential of disaster-prone areas, processing of secondary data, and analysis using remote sensing. The results of this study are that the rocks in the West Bandung area are divided into groups of volcanic rocks, sedimentary rocks, and alluvial deposits. The volcanic rock group got a score of 3 because it was considered more prone to erosions than the sedimentary and alluvial rock groups which were scored 2 and 1. with a weighted level of disaster vulnerability. The zone of high disaster susceptibility is considered to have the highest probability of a disaster occurring. Therefore, in the final result, the overlap between the distribution of the potential for minerals and the zone of high disaster susceptibility results in a potential area for minerals that are relatively safe from disasters, both soil movement, and flooding. Potential mining resources in West Bandung Regency are Andesite basalt 1,860,412 ha (1.43%), Limestone 667.05 ha (0.50%), Sirtu 40,949.76 ha (31.35%%).

Abstract

Abstract. Coal is a sedimentary rock produced from peat and rock formation processes in swamp basins. Indonesia has a coal-producing State-Owned Enterprise (BUMN), namely PT XYZ Tbk, which is located in Tanjung Enim, South Sumatra. In general, coal will experience a decrease in quality due to self-burning and long storage times (livestock). Spontaneous combustion is a self-combustion process without any external heat source due to an exothermic oxidation response, which causes an increase in temperature. Spontaneous combustion that occurs in coal causes the coal to be separated from stockpiles and cannot be sold; if this continues continuously, it will result in losses for the company. Research results are divided into research observations and research measurements. Based on these results, this research reveals that several factors, such as embankment temperature, environmental temperature, wind direction, wind speed, trenching system, demolition system, and embankment system, influence the causes of spontaneous combustion at PT XYZ Tanjung Enim. Spontaneous combustion can be prevented through LIFO management in the demolition system, controlling the stockpile height, trenching system, and compacting the stockpile. Meanwhile, preventing spontaneous combustion can be done through LIFO management in the demolition system, controlling the stockpile height, trenching system, and compacting the stockpile. Abstrak. Batubara merupakan jenis batuan sedimen yang dihasilkan dari proses penggambutan dan pembatubaraan dalam cekungan di rawa-rawa. Indonesia memiliki perusahaan Badan Usaha Milik Negara (BUMN) penghasil batubara yaitu PT XYZ Tbk yang terletak di Tanjung Enim, Sumatera Selatan. Pada umumnya, batubara akan mengalami penurunan kualitas yang disebabkan oleh terjadinya swabakar akibat waktu penyimpanan yang lama. Swabakar (Spontaneous combustion) adalah proses pembakaran tanpa adanya sumber panas dari luar dikarenakan respon oksidasi eksotermis yang menyebabkan peningkatan temperatur. Swabakar yang terjadi pada batubara menyebabkan batubara tersebut harus dipisahkan dari timbunan dan tidak dapat dijual, apabila hal ini berlangsung secara terus menerus akan mengakibatkan kerugian pada perusahaan. Hasil penelitian dibagi menjadi pengamatan penelitian dan pengukuran penelitian. Berdasarkan hasil tersebut penelitian ini mengungkapkan bahwa penyebab terjadinya swabakar di PT XYZ Tanjung Enim dipengaruhi oleh beberapa faktor seperti temperatur timbunan, temperatur lingkungan, arah angin, kecepatan angin, sistem paritan, sistem pembongkaran, dan sistem penimbunan. Sementara itu, untuk mencegah swabakar maka dapat dilakukan melalui manajemen LIFO pada sistem pembongkaran, melakukan kontrol pada ketinggian stockpile, sistem paritan, dan juga dilakukannya pemadatan pada stockpile.

Abstract

Abstract. The formation of the Tin Path in Indonesia from the Riau Islands to the Bangka Belitung Islands cannot be separated from the tectonic order of Southeast Asia, especially Myanmar, Thailand and Malaysia, this is because these areas were formed through the same geological process and period of tectonism. The formation of the Indonesian tin route was caused by the collision (collision) between the Sibumasu Plate and the Indochina Plate. During this collision process, tin enrichment occurred. Initially, before the collision, the position of the Sibumasu Plate and the Indochina Plate was separated by the Paleo-Tethys (oceanic plate). Production Suction Vessel is a modernization of tin mining that uses Cutter as its main excavation tool and is a digging or earthmoving tool used to excavate underwater soil layers, where underwater, where mechanical and mechanical equipment and material processing material processing rests on a pontoon a pontoon. Selanjutnya material from the excavation is transferred to the temporary processing section. Abstrak. Pembentukan Jalur Timah di Indonesia mulai daerah Kepulauan Riau hingga Kepulauan Bangka Belitung tidak dapat dipisahkan dari tatanan tektonik Asia Tenggara khususnya Myanmar, Thailand dan Malaysia, hal ini dikarenakan daerah-daerah tersebut terbentuk melalui proses geologi dan periode tektonisme yang sama. Terbentuknya jalur timah Indonesia disebabkan oleh tumbukan (kolisi) antara Lempeng Sibumasu dengan Lempeng Indochina. Selama proses tumbukan inilah terjadinya pengkayaan timah. mula-mula sebelum terjadinya tumbukan, posisi Lempeng Sibumasu dan Lempeng Indochina dipisahkan oleh Paleo-Tethys (lempeng samudera).
