Mineral and coal resources and reserves in the world even in Indonesia need to be known, considering that until now more and more industries need it, so that it can cause a reduction in raw material supply for the industry. To find out the amount of resources and reserves, data or information is needed, so after knowing the relevant information, it is expected to know what strategies to do. The method used is the comparison between Indonesian data and world data so that the percentage of ownership in Indonesia can be known. The results showed that coal in Indonesia was estimated to range from 2% -3% of coal in the world. For metal minerals, Indonesia had 6.08% nickel, 6.82% cobalt, 14.05 lead, 9.63% zinc, 3.33% bauxite, 0.72 iron, 4.63 gold, 16.67% tin , 3.29% copper, 19.17 manganese, 0.44% chromium, 0.17 titanium.

Coal is one of the fossil fuels that can be utilised in various industries including the electric power industry, cement industry, paper industry, steel industry, and other industries. It is approximately 70 percent of Indonesian coal production utilised for the supply of domestic electricity, while 10 percent used for cement production, and the rest utilised for industrial fuel and metallurgical processes. In addition to coal, wood is also another source that is often used among the certain communities as biomass energy source. It is obvious that coal and biomass can be used as energy sources, which can be one of the drivers of economic growth (Gross Domestic Product). Therefore, the shortage of these energy sources can be an obstructive factor for the economic acceleration. The purpose of this study is to figure out the reciprocal relationship between the three variables. The method used in this study is Granger causality. The results indicate that there is a positive relationship between GDP and coal consumption, meaning that the use of coal is influenced by GDP. On the other hand, economic growth may also results in an increase in coal consumption.

One of mining industry characteristics is non renewable, therefore its management should be optimal, efficient and environmentally oriented. Indonesian government has established the mining law as a main regulation in carrying out mineral and coal mining activities. The regulation related to mining industry was Act No. 11/1967, which then replaced by Act No. 04/2009. Implementing rule of the Act No. 04/2009 is regulated through a Government Regulation (PP). In order to implement this government regulation, a Minister Regulation is then need to be issued. The main objective of this research is to know the development of the downstream mining industry related to increasing value added, especially nickel. The method used in this study is a descriptive method that describes secondary data in the form of documentation obtained from various sources. The results shows that the implementation of Act No. 04/2009 has ogbligated the maning companies to built their smelters to run mineral processing and metal refining in five years, in which it can increase value added of minerals, including nickel. Therefore, according to the act, in 2014 raw ore exports should be banned. This condition results in a decrease of raw ore export. The construction of a smelter is used to process and purify nickel with levels above 2%. However, in Indonesia there is still nickel ore with levels below that level. Therefore, Ministerial Regulation No. 05/2017 was issued to overcome this problem, which is currently being replaced by ministerial regulation No. 25/2018.

The increasing demand for sand and stone materials has resulted in competitions between mining companies in order to meet the need of the material for construction activities, from which it results in conflicts between two parties, two people, or groups of people. Part of the mathematical programming technique used to analyze the decision-making process of competition between two or more parties is Game Theory. The application of game theory is to produce the best strategy that will be used by a company to optimize the marketing of gravel fraction. Instruments or tools used in the research is a questionnaire that includes improving product quality, affordable pricing, improving service quality, establishing an effective corporate work process, and determining the place of inventory. The result is arranged in the form of a payoff matrix and analyzed using the Game Theory, that indicates the competition between PT X and PT Y. The analysis results show that the implementation of those strategies is the best way that can optimize marketing of gravel fraction, so that it can improve the position of profit or loss got saddle point from competition between PT X and PT Y, which is 11. The results also confirm the increase of profit of PT X, from 10 to 11 by applying effective work processes (probability 5:1). In addition, the loss of PT Y could decrease from 12 to 11 by applying strategies to improve the product quality of gravel fraction and determining the stock of the fraction (probability 1:1).

RECOMMENDED STUDY OF EXTINGUISHING METHODS BASED ON THE 1994 PETTIFER AND FOOKES CRITERIA APPROACH TO THE PLANNING OF THE TRANS-PAPUA WASIOR-NABIRE ROAD: STUDI REKOMENDASI METODE PENGGALIAN BERDASARKAN PENDEKATAN KRITERIA PETTIFER DAN FOOKES 1994 PADA PERENCANAAN RUAS JALAN TRANS PAPUA WASIOR-NABIRE Arif Setiawan; Sampary William Wakum; Ismiyati; Louis Hermanus Lamma

The road is one of the traffic infrastructures for driving which supports all community activities. One of the stages of road construction is land clearing, in which one of the activities is eviction or excavation. The road construction location is the Trans Papua Wasior-Nabire road, Yamor District, Kaimana Regency, West Papua Province. However, the problem in this study is whether the excavation method is suitable for excavating material for road construction. Based on these problems, the purpose of this study is to recommend a method of excavation on the Trans Papua Wasior-Nabire road section. The method used is the Pettifer and Fookes (1994) criterion approach to determine the capability method. The results obtained with this approach indicate that the KM 501+500 excavation site is included in the level of easy digging capability or enters into a condition that is easy to dig. At the KM 502+100 excavation site, it is included in the hard digging capability level or a category that is difficult to dig because of the condition of the material which is difficult to dig, so the recommendation given is to use heavy equipment, namely a hydraulic excavator (backhoe) or a power shovel.

Pemilihan jenis penyangga dalam memastikan kestabilan lubang bukaan menjadi salah satu yang harus diperhatikan dengan serius. Hal ini bisa berdampak pada ketidakstabilan dan berakhir dengan terjadinya runtuhan lubang bukaan tersebut. Oleh karena itu, perlu dilakukan analisis terkait yang tentunya memerlukan metode yang mampu mengakomodasi berbagai variabel guna mendekati kondisi sebenarnya. Metode probabilitas seperti yang dikemukakan oleh Arif (2016), mampu mengakomodasi setiap variasi data karakteristik dari parameter yang hasilnya dinyatakan dalam bentuk probabilitas kelongsoran (PK). Dalam penelitian ini, digunakan kombinasi metode RMR’89, Numerik dan Probabilitas yang menjadi suatu rangkaian proses analisis guna saling melengkapi dan mendukung untuk mencapai hasil yang lebih akurat. Selain itu kriteria keruntuhan yang digunakan yaitu mohr coulomb dengan nilai FK minimal sebesar 1,5 juga analsisis monte carlo untuk metode probabilitas.Hasil penelitian menunjukkan nilai RMR sebesar 42 (fair rock) dan jenis penyangga yang direkomendasi oleh Bieniawski (1989) yaitu rockbolt (panjang 4 m, spasi 1,5 m), shotcrete tebal 100 mm dan wiremesh. Namun saat dianalisis dengan metode numerik dan probabilitas, jenis penyangga tersebut tidak efektif karena diperoleh nilai FK rata – ratanya 1,21 dengan probabilitas keruntuhan 89,59 %. Untuk itu dilakukan modifikasi jenis penyangga yang akhirnya diperoleh jenis penyangga yang sesuai kriteria nilai FK dan probabilitas lebih kecil yaitu kombinasi rockbolt (panjang 4 m, spasi 1,5 m), shotcrete tebal 100 mm, wiremesh dan H-Beam. Adapun nilai FK rata – ratanya 1,6 dengan probabilitas keruntuhan 33,07 %.Kata Kunci : Penyangga, RMR, Numerik, Probabilitas
