The mining industry is one of the industries that has caused environmental damage. It is not only deforestation, but pollution, groundwater, and air problems caused by the mining industry. Departing from the worsening ecological conditions due to development, the mining industry became environmentally friendly by adopting the so-called green mining. This article wants to examine the application of green mining in Indonesia to find out the main strategies they carry out by mining companies. Through descriptive analysis, this article finds that the green mining industry in Indonesia is organized through cooperation between the government, mining companies, investors, and researchers. The association is practiced through the so-called green policy, green management, green investment, and green technology.

The purpose of this research is to find out the influence of Green Accounting implementation and total asset turnover to profitability applied by foreign mining companies in Indonesia. While these companies play an important role in industry, they exploit natural resources and environment to raise their standards and earn maximum profits without concerning the surrounding conditions. The companies’ activities that cause negative impacts on society can reduce the investors’ trust and will eventually destroy their own image. Mining companies apply the Green Accounting concept in order to overcome the risks of natural disasters caused by their activities. The samples of this study include 5 foreign mining companies that have been operating in Indonesia for 6 years. Sample collection uses Non-probability sampling method and purposive sampling technique. Various methods of data analysis are performed to process the collected data to prove the effects of the two independent variables on the dependent variable. The results of this study show that the application of Green Accounting partially has no effect on profitability of the mining companies because social and environment costs are not transparent in their financial statements. However, Total Asset Turnover partially affects the profitability of the companies and tends to increase every year. The application of Green Accounting and Total Asset Turnover simultaneously affect the profitability of the mining companies as the environmental condition needs to be considered in carrying out their operations. As a result, environmental performance has a significant influence on the companies’ finance. Keywords: Green Accounting, Total Asset Turnover, and Profitability

Issues related to the green industry and environmental accounting are urgent to be formulated by the government. The concept of environmental accounting for companies encourages the ability to minimize environmental problems. Environmental accounting will produce a quantitative assessment of the costs and impacts of environmental protection. The purpose of this study is to describe the extent of disclosure of carbon emissions and to describe the legal regulations in Indonesia which regulate ecological disclosure. This study also examined the effect of the Environmental Performance Awards on the quality of environmental exposure. The samples are 35 companies engaged in mining, energy, chemistry, pharmaceuticals, cosmetics, food, and beverages that are listed on the Stock Exchange in 2012-2016. The data analysis method used is Ordinary Least Square (OLS). The result reveals that the practice of environmental disclosure at high profile companies on the Indonesia Stock Exchange is still low. This shows that the company’s management awareness of environmental exposure does not comply with the Decree of the Chairperson of the Capital Market and Financial Institution Supervisory Agency Number: KEP-431/BL/2012 concerning Submission of the Annual Report. The results showed that the Environmental Performance Awards variable had a significant positive effect on the quality of environmental disclosure.

This study aims to test and analyze the influence of green intellectual capital and company size on business sustainability. The selection of samples was conducted by purposive sampling under the objectives of this study, namely mining companies registered in IDX from 2017-2020. The findings of this study show that green human capital and green structural capital have a significant effect on business sustainability, while green relational capital does not affect business sustainability. In addition, company size has a positive impact on business sustainability. By examining the factors that affect sustainability, this study paves the way for further investigation of this topic with a set of micro and macro variables. This research provides insight into the disclosure of green intellectual capital to business sustainability. The GIC research in Indonesia has been claimed that it has not been widely researched. Accordingly, this research seems to be preliminary. This research also considers the current context of the era of agility and hybrid cloud and the increasing competition in the advanced industry. The company is likely to try to find a strategy to maintain the sustainability of its business.

The world's energy sources have seen various transformations, with the majority first relying on biomass such as firewood to satisfy their energy demands, before transitioning to fossils such as coal, oil, and natural gas as a result of the industrial revolution. Indonesia, like other rising market nations, faces issues in satisfying its domestic energy demand. Dependence on fossil energy sources presents its own challenges. This study is focused on the constraints associated with green growth policy in East Kalimantan. The purpose of this paper is to address three questions: first, to reiterate the importance of developing more comprehensive energy transition strategies in Indonesia. This is accomplished by comparing data on the availability of energy sources to data on Indonesia's expanding energy demands. Second, how to establish an energy transfer policy that takes into consideration Indonesia's conditions and potentials, as well as the problems that must be solved. Third, how to position the mining and coal sector as a key component of the energy transformation process, especially given the long-term character of the transformation process, while reaching energy sufficiency is a problem that demands immediate attention. To discuss this, the author uses qualitative methods with case studies. The results showed that in general, a number of prerequisites need to be met to make coal and nickel a transitional element, namely: infrastructure, resources, economic aspects, and national energy policies. To increase the contribution of New and Renewable Energy in the National Energy Mix, there are still a number of problems and challenges, both from the policy and regulatory aspects to support the development of NRE, the aspect of providing accurate data, the financial aspect for developing NRE for private investors, and the aspect of providing technology and infrastructure to support private investment in the NRE sector.

The article describes the global coal market as the ratio of demand and supply depending on the development of energy technologies in the historical section. The continental specificity of coal mining is given. The basic world exporters and importers of coal and their role in the sale of energy fuels are analyzed. The key coal producing countries are China, India, the USA, and Australia. The largest consumers of coal products are China, India, Japan and Korea. There are unconditional leaders in the export coal market: Indonesia and Australia. In addition, a comparison of large coal companies and their share in the world market is presented. The features of coal supplies are analyzed in accordance with international rules (Incoterms), which regulate the rights and obligations of the buyer when conducting international trade, as well as determine the moment of transfer of risks from the seller to the buyer. The following supply bases were characterized: FOB (Free On Board), FAS (Free Alongside Ship), CIF (Cost Insurance and Freight), DAP (Delivered At Place), FCA (Free Carrier) etc. Trends in the logistics component of the global coal industry are revealed. Logistic of coal supply chains in comparison with other energy fuels and their features are disclosed. The problem of profitability of mines and their effectiveness is presented. Assessment of the environmental components of coal use in industry and energy is analyzed. It was noted that on the background of the trend to protect the environment and promote renewable energy, coal is becoming less popular in developed countries. This trend is further exacerbated by state subsidies for green energy.

Ancient and modern types of sedimentary placer deposits formed in both alluvial and coastal environments have been signficant sources of the rare earth elements (REEs). The REE-bearing minerals in placer-type deposits are primarily monazite [(Ce,La,Nd,Th)PO4] and sometimes xenotime (YPO4), which are high-density (heavy) minerals that accumulate with the suite of heavy minerals. Monazite has been extracted from many heavy mineral placers as a coproduct of the economic recovery of associated industrial minerals, such as titanium oxide minerals (ilmenite, rutile), zircon, sillimanite, garnet, staurolite, and others. Xenotime has been produced from some alluvial deposits as a coproduct of tin (cassiterite) placer mining. Placers are mineral deposits formed by the mechanical concentration of minerals from weathered debris. Placers can be classified as eluvial, alluvial, eolian, beach, and fossil (paleo) deposit types. Monazite-bearing placer-type deposits can occur in residual weathering zones, beaches, rivers and streams, dunes, and offshore areas. The detrital mixture of sand, silt, clays, and heavy (dense) minerals deposited in placers are derived primarily from the erosion of crystalline rocks, mainly igneous rocks and moderate- to high-grade metamorphic rocks (amphibolite facies and higher). In fluvial settings, slope is an important factor for the concentration of heavy minerals from detritus. In coastal settings, the actions of waves, currents, tides, and wind are forces that concentrate and sort mineral particles based on size and density. Placer deposits containing monazite are known on all continents. In the past, by-product monazite has been recovered from placers in Australia, Brazil, India, Malaysia, Thailand, China, New Zealand, Sri Lanka, Indonesia, Zaire, Korea, and the United States. More recently, monazite has been recovered from coastal and alluvial placers in India, Malaysia, Sri Lanka, Thailand, and Brazil. In particular, along the southwestern and southeastern coasts of India, beach deposits rich in heavy minerals have experienced renewed exploration and development, partly to recover monazite for its REEs as well as its Th, to be used as a nuclear fuel source. Exploration designed to locate heavy mineral placers in coastal environments should identify bedrock terranes containing abundant high-grade metamorphic rocks or igneous rocks and identify ancient or modern coastal plains sourced by streams and rivers that drain these terranes. Trace elements associated with heavy mineral placers, useful as pathfinder elements, primarily include Ti, Hf, the REEs, Th, and U. Radiometric methods of geophysical exploration are useful in discovering and delineating deposits of heavy mineral sands. Several minerals in these deposits can produce a radiometric anomaly, but especially monazite, due to its high thorium content. Some beach districts in India and Brazil have been demonstrated as areas of high background radiation with potential dose exposure to humans and others, primarily due to the Th and U in detrital grains of monazite and zircon. Monazite- or xenotime-bearing placers offer several advantages as sources of REEs. Ancient and modern deposits of heavy mineral sands that formed in coastal settings can be voluminous with individual deposits as much as about 1 km wide and more than 5 km long. Grains of monazite or xenotime in placer deposits are mingled with other heavy minerals of industrial value. Monazite and xenotime are durable and often the heaviest minerals within the sand-silt deposit, which makes them relatively easy to mechanically separate. Thus, the REE ore minerals, monazite or xenotime, can be recovered from heavy mineral placers as a low-cost coproduct along with the economic production of the associated industrial minerals. This special volume provides a comprehensive review of the current state of knowledge for rare earth and critical elements in ore deposits. The first six chapters are devoted to rare earth elements (REEs) because of the unprecedented interest in these elements during the past several years. The following eight chapters describe critical elements in a number of important ore deposit types. These chapters include a description of the deposit type, major deposits, critical element mineralogy and geochemistry, processes controlling ore-grade enrichment, and exploration guides. This volume represents an important contribution to our understanding of where, how, and why individual critical elements occur and should be of use to both geoscientists and public policy analysts. The term “critical minerals” was coined in a 2008 National Research Council report (National Research Council, 2008). Although the NRC report used the term “critical minerals,” its focus was primarily on individual chemical elements. The two factors used in the NRC report to rank criticality were (1) the degree to which a commodity is essential, and (2) the risk of supply disruption for the commodity. Technological advancements and changes in lifestyles have changed the criticality of elements; many that had few historic uses are now essential for our current lifestyles, green technologies, and military applications. The concept of element criticality is useful for evaluation of the fragility of commodity markets. This fragility is commonly due to a potential risk of supply disruption, which may be difficult to quantify because it can be affected by political, economic, geologic, geographic, and environmental variables. Identifying potential sources for some of the elements deemed critical can be challenging. Because many of these elements have had minor historic usage, exploration for them has been limited. Thus, as this volume highlights, the understanding of the occurrence and genesis of critical elements in various ore deposit models is much less well defined than for base and precious metals. A better understanding of the geologic and...

Companies, including PT Vale Indonesia (PTVI), generally should implement inventory control. PTVI use approximately 32,077 tons per month coal as a heating catalyst on the reducing furnace. There were several periods in 2017 and 2018 where the coal inventory exceed the safety stock and maximum stock level with the total cost of IDR 616,059,680.00 in 2017 and IDR 669,720,480.00 in 2018. In order to analyze and solve that stock problems, this research used the Lot-Sizing technique with Lot for Lot (LFL), Economic Order Quantity (EOQ), Part Period Balancing (PPB), and the Silver-Meal Algorithm (SMA) methods to obtain the demand and appropriate order time, by considering the lead time factor, safety stock, and reorder point to obtain the efficient costs. As a result, the safety stock value was 7,922 tons with reorder point 18,674 tons. The PPB and SMA methods gave the most minimum total inventory cost of IDR 437,021,589,280 and efficiency of 34.74%.

There are two types of investors, the first is the type of investor who focuses on return on investment and the second type is the investor who pays attention to Environmental, Social, and Governance (ESG) values in investing. This requires management to make adjustments to create a competitive advantage. One of the frameworks used to measure the competitive advantage of a company is the Porter framework. However, Porter's framework needs to be supplemented with ESG values to capture the value creation process in today's business environment. This research is applied research by applying the existing framework in the field. In this case, the framework used consists of two, namely the Porter framework and the LST integration framework. The ESG framework is implemented at the industrial level using industrial divisions based on industrial divisions in the Indonesia Stock Exchange. This study focused on the raw material production sector, namely agriculture, and mining. This study showed that ESG factors affected the competitive advantage of companies and industries. If a company in an industry ignores the value of ESG, the company will experience a decrease in competitiveness. Meanwhile, if the industry does not pay attention to the ESG factor, the industry will experience a decline compared to other industries that pay attention to the ESG factor.

Copper resistant bacteria can be isolated from environments where copper levels are abundant from mining, industrial, or agricultural activities. The aim of this work was to study the molecular and physiologicalcharacteristics of indigenous copper resistant bacteria isolated from activated sludge in an industrial wastewatertreatment plant in Surabaya, Indonesia. The bacterial isolates were designated as strains IrC1, IrC2, and IrC4. Phylogenetic analysis based on 16S rDNA sequence analysis identified isolates IrC1, IrC2, and IrC4 as Acinetobacter oleivorans (98.41% similarity), Acinetobacter pitii (97.22% similarity), and Cupriavidus pauculus (96.99 similarity), respectively. The addition of 5 mM of CuSO4 in the medium affected morphological 4 appearance of all isolates to green and undulate margin might be due to the survival mechanism of bacteria by absorbing the copper. This studies indicated that copper resistance mechanism of all isolates was facilitated through the bioaccumulation of copper inside the cell, especially on the membrane fraction and inside the cytoplasm, albeit at a limited amount. It was observed that isolates IrC1, IrC2, and IrC4 were capable of accumulating 137.23 , 364.66 , and 272.07 mg L-1 of copper, respectively from the medium containing 8 mM CuSO4. The capability of isolates IrC1, IrC2, and IrC4 to accumulate copper can be exploited in bioremediation 4 process for removing copper from industrial sewage.

ABSTRAK ANTAM adalah perusahaan pertambangan yang memiliki praktik pengelolaan sosial dan lingkungan yang telah sesuai bahkan melampaui ketentuan hukum di Indonesia dan standar internasional. Oleh karena itu, ketika terdapat kebutuhan dari para perajin dan pedagang perhiasan di Indonesia untuk bisa menembus pasar internasional yang semakin memerhatikan keberlanjutan, ANTAM ada dalam posisi sebagai mitra pemasok bahan baku yang dipersyaratkan. ANTAM bukan semata-mata melakukan penjualan kepada mereka, melainkan juga berkontribusi dalam memberikan pengetahuan, keterampilan, dan akses yang dibutuhkan para perajin dan pedagang itu. Dalam bisnis perhiasan, konsep green business dapat dilihat dengan adanya Responsible Jewelry Council (RJC) dan Fairtrade International yang merupakan organisasi international yang memiliki kepedulian dalam mempromosikan praktik industri perhiasan yang sesuai dengan seluruh aspek tanggung jawab sosial untuk mencapai keberlanjutan. Kedua organisasi tersebut adalah anggota dari ISEAL (International Social and Environmental Accreditation and Labelling). RJC memiliki 500+ anggota yang melakukan kegiatan penambangan, pengolahan dan pemurnian, pembuatan perhiasan, sampai dengan pelaku usaha penjualan perhiasan. RJC Code of Practice mencakup di antaranya standar hak asasi manusia, hak pekerja, dampak lingkungan, publikasi atau penjelasan tentang produk dan beberapa topik lainnya yang dimutakhirkan terakhir pada tahun 2013 yang di antaranya mengacu pada UN Guiding Principles on Businesses and Human Rights yang dikeluarkan oleh PBB dan memasukkan ketentuan mengenai sumber bahan baku yang bebas konflik. Sertifikasi RJC juga membantu perusahaan dalam kemamputelusuran suatu produk, uji kelayakan rantai pasokan, dan penggunaan standar tersebut terus meningkat. Fairtrade International juga bergerak dalam bidang yang sama, namun lebih fokus pada tambang rakyat dan komunitasnya. ISEAL mendukung para penambang untuk meningkatkan hubungan jangka panjang dan adil untuk memastikan bahwa pertambangan dapat menekan angka kemiskinan dan mendukung terwujudnya pembangunan berkelanjutan. ANTAM membantu para perajin dan pedagang perhiasan untuk dapat memenuhi standar internasional itu, selain menjadi pemasok bahan bakunya. Penjualan ANTAM meningkat seiring dengan semakin banyaknya perajin dan pedagang yang bisa memenuhi standar internasional. Kasus kolaborasi antara ANTAM dengan para perajin dan pedagang perhiasan di Bali yang dipaparkan menunjukkan bahwa gagasan Porter dan Cramer (2011) tentang creating shared value (CSV) bisa dilaksanakan oleh industri pertambangan, dengan menggabungkan pengembangan masyarakat (community development) dan pengembangan bisnis (business development). ABSTRACT ANTAM is a mining company that has social and environmental management practices that comply with and even exceed Indonesian legal requirements as well as meet international standards. Therefore, when there is a need from crafters and jewelry traders in Indonesia to be able to penetrate the international market which is increasingly concerned about sustainability, ANTAM is in a position as a supplier of required raw materials. In the jewelry business, the concept of green business can be seen with the Responsible Jewelry Council (RJC) and Fairtrade International, which is an international organization that has a concern in promoting the practice of the jewelry industry in accordance with all aspects of social responsibility to achieve sustainability. Both organizations are members of ISEAL (International Social and Environmental Accreditation and Labeling). RJC has 500+ members who carry out mining, processing and refining activities, jewelry making, to business people selling jewelry. The RJC Code of Practice includes human rights standards, workers' rights, environmental impacts, publications or explanations about products and several other topics, most recently updated in 2013, among which refer to the UN Guiding Principles on Businesses and Human Rights issued by the United Nations and include provisions regarding conflict-free sources of raw materials. RJC certification also helps companies in product traceability, supply chain feasibility testing, and the use of these standards continues to increase. Fairtrade International is also engaged in the same field, but is more focused on the mining of the people and their communities. ISEAL supports miners to improve long-term and equitable relations to ensure that mining can reduce poverty and support sustainable development. ANTAM is helping crafters and jewelry traders to be able to meet these international standards, in addition to being a supplier of raw materials. ANTAM's sales have increased along with the increasing number of craftsmen and traders who can meet international standards. The case of collaboration between ANTAM and crafters and jewelers in Bali presented shows that the idea of Porter and Cramer (2011) about creating shared value (CSV) could be implemented by the mining industry, by way of combining community development and business development.

Conservation and tourism contribute to greener economic growth in many countries. Although protected areas have often been viewed as land excluded from economic development for the purposes of environmental conservation, many countries have realized their powerful economic potential through tourism and visitation. In fact, tourism has been an integral part of protected area management since the beginning of their conception. If appropriate policy and technical capacity are established, most protected area professionals argue that both ecosystem protection and tourism development can be implemented concurrently without undermining the objectives of either activity. Lao PDR policy makers have recognized the economic potential of protected areas and seek to develop these sites as a focus of the NSEDP 2015-2019 and the 2030 National Green Growth Strategy, given the globally unique natural heritage of Lao PDR. Not only does tourism in protected areas provide employment opportunities to youth and ethnic peoples, but tourism is also one of the few sectors with high female labor participation above parity (including in Indonesia, Malaysia, Philippines and Thailand).7 Many jobs in protected area management and tourism operations often do not require high levels of education, providing lower barriers to acquire employment for poor communities with properly supported with policy and regulations. Furthermore, these jobs and incomes can often be more sustainable than those in mining or timber activities due to boom and bust cycles from extractive industries. Finally, tourism jobs are often safer than comparable extractive jobs.

As a consequence of recent human activities. populations of approximately 75% of the world’s primates are in decline, and more than 60% of species (n = 512) are threatened with extinction. Major anthropogenic pressures on primate persistence include the widespread loss and degradation of natural habitats caused by the expansion of industrial agriculture, pastureland for cattle, logging, mining, and fossil fuel extraction. This is the result of growing global market demands for agricultural and nonagricultural commodities. Here, we profile the effects of international trade of forest-risk agricultural and nonagricultural commodities, namely soybean, oil palm, natural rubber, beef, forestry products, fossil fuels, metals, minerals, and gemstones on habitat conversion in the Neotropics, Africa, and South and Southeast Asia. Total estimated forest loss for these regions between 2001 and 2017 was ca 179 million ha. The average percent of commodity-driven permanent deforestation for the period 2001–2015 was highest in Southeast Asia (47%) followed by the Neotropics (26%), South Asia (26%), and Africa (7%). Commodities exports increased significantly between 2000 and 2016 in all primate range regions leading to the widespread conversion of forested land to agricultural fields and an increase in natural resource extraction. In 2016, US $1.1 trillion of natural-resource commodities were traded by countries in primate range regions. The Neotropics accounted for 41% of the total value of these exports, Southeast Asia for 27%, Africa 21%, and South Asia 11%. Major commodity exporters in 2016 were Brazil, India, Indonesia, Malaysia and South Africa, countries of high primate diversity and endemism. Among the top 10 importers were China, the US, Japan, and Switzerland. Primate range countries lag far behind importer nations in food security and gross domestic product per capita, suggesting that trade and commodity-driven land-use have done little to generate wealth and well-being in primate habitat countries. Modeling of land-use and projected extinction of primate species by 2050 and 2100 under a business as usual scenario for 61 primate range countries indicate that each country is expected to see a significant increase in the number of species threatened with extinction. To mitigate this impending crisis, we advocate the “greening” of trade, a global shift toward a low-meat diet, reduced consumption of oil seed, diminished use of tropical timber, fossil fuels, metals, minerals, and gemstones from the tropics, accompanied by a stronger and sustained global resolve to regulate and reverse the negative impacts of growing unsustainable global demands and commodity trade on income inequality, and the destruction of primates and their habitats.
