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.

PT. X is one of the companies engaged on andesite mining and crushing. Currently the PT X crusher factory produces 233.3 tons/day of andesite with 2 crusher units, with the demand of 200 - 300 tons/day. The production is expected to be 468.8 tons/day if the third crusher has been built. However, market demand increased to 1100 tons/day. Therefore PT X plans to build a new crusher plant on a new location, because the current location is insufficient if added to any other crusher unit. In the construction of a new crusher plant, a crusher plant design is needed to obtain what tools are needed to obtain the desired production target, and to determine the setting of the crusher. The problem that occurs is that a new crusher plant design is needed for production of 800 tons / day on condition that the product size of -20 + 10 mm is the largest percentage of the whole, more than 28%. In designing a new crusher plant, some data is needed including: material size distribution in the stockyard, effective working time, efficiency of each deck screen, and the location of the establishment of a new crusher plant.

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.

Geologically the Windesi area is composed of sedimentary rocks from the Kembelangan Group, which are in the Middle Jura to the Middle Miocene. The Kembelangan group suppressed in harmony with Imskin limestone (KTi) which is in the Upper Cretaceous to the Middle Miocene. Thus, it has quite a variety of mineral potential. Potential Mineral Resources in the Windesi District are classified as Non-Metallic Minerals consisting of limestone, sandstone, shale and assorted gravels. Possible occurrence of limestone in Windesi District found in Wamesa Tengah village, Windesi village, Sombokaro village, Yopmios village and Sandey village with an estimated reserve area of 3,093,325 Ha. Sandstones found in Sandey village and partly in Wamesa Tengah village, as well as in Windesi village. The possible occurence of sandstone in the Windesi District area is quite large with an estimated reserve area of 156,290.51 Ha. Shale scattered in the middle of Sandey village and in the northern part of Windesi village and partly in Yopmios village with a reserve area of approximately 414,845.19 Ha. Assorted gravels potential found in Sandey village in the west and along the coast of Tanjung Ronsore in the north to northeast with a reserve area of approximately 2,973.17 Ha.

This paper discusses the comparison of acid calculation required on carbonate matrix acidizing between volumetric method and by considering the wormhole formation mechanism. Normally the standard estimation of the required acid volume in carbonate rocks is based on volumetric method where the acid will be distributed evenly to all direction in the targeted formation. However the real acid mechanism at carbonate rock is affected by the creation of wormhole. This case study compares the amount of acid volume to both scenarios. The result shows more optimistic result for volumetric method compared to the wormhole influences.

Mangrove and Bekantan (Nasalis larvatus) conservation areas (KKMB) in Tarakan City is a mangrove city forest area that in the development stage sepecially for Bekantan population and mangrove ecosystem at large. With an area of about 22 hectares and at least 11 protected animal species includes Bekantan, the KKMB has become iconic tourism attraction. This not only of the rarity of the attraction but also because of this kind of venue is the only one in the world. This research aimed to find out the management, the uniqueness and the obstacles faced in managing KKMB. The methods used are interview, observation and literature study. The data obtained are compiled, processed, and analyzed with descriptive qualitative analysis methods, by providing an overview of the situation or events and phenomena in the field. From the study, we could understand that the KKMB is manage by the Tarakan City Tourism Office. The retribution came from KKMB are deposited to the Tarakan City Revenue Service. Furthermore, the uniqueness of KKMB that attracts tourists to visit due to its strategic location in the middle of the urban area adjacent to the shopping centers, settlements, fishponds, companies, and access roads / ports. Two main attraction of the KKMB are bekantan (proboscis mongkey) endemic to Borneo and The red mangrove (Rhizophoraa Apiculata). Last, the problem faced by the management of KKMB are no clear organizational structre and waste management that come from tides, domestic waste, and visitors. Also in KKMB there is no clear organizational structure.

To increased the production, the Deep Ore Zone (DOZ) mining department has a concept of implementing a staggered crew. Staggered crew is a crew formed specifically to support production activities. To assess the performance of the application of the staggered crew, an evaluation of the factors that influence production activities is carried out. Factors that subject to evaluation are working time, number of operators and production capability. The results of evaluating work time (optimum efficiency) for crew I, II, and III showed as follow 29%, 30%, and 28% respectedly. Very low efficiency is due to time constraints in operation, which are affected by delay time, idle time and maintenance time. Average productive work time (work) is 3.26 hours/day, delay time is 3.26 hours/day, idle time is 4.03 hours/day and maintenance time is 0.53 hours/day. Idle time is the highest time of these four parameters. The results also showed that there were differences in the number of distribution operators, namely crew I numbered 16 people, crew II numbered 12 people and crew III numbered 15 people. But the number of operators on each crew is still sufficient to support production activities. The average production is 62.14 tons/hour and 4,784.78 tons/day. So with a production of 62.14 tons/hour and working time of 11 hours/day, it takes a minimum of 8 dump truck operators to reach a value of 5,468.32 tons/day.
