Dermatitis Secondary to Exposure to Nickel and Fragrance at Workplace: A Case Report

/in /by

Allergic contact dermatitis may be caused by exposure to chemicals. The skin usually develops type IV sensitivity where the initial sensitization may occur a few days but it may take years to develop in low grade exposure to these allergens. In the present study, the patient sustained the disorder through exposure to nickel sulfate, balsam of Peru and a fragrance mix which was confirmed by conducting a Patch test. The initial patient’s Investigator’s Global Assessment, Eczema Area and Severity Index, Dermatology Life Quality Index and Patient-oriented Eczema Measure scores were 3, 9.6, 6 and 14, respectively and improved to 1, 0.6, 1 and 1, respectively after two months of intervention. Good occupational hygiene is vital such as wearing polyvinyl chloride gloves to avoid nickel contact and effective handwashing practices to prevent nickel buildup on the hands. Avoidance of contact of fragrances in cleaning products averts contact dermatitis.

Nickel Price Projection Using Multivariate Regression Method and Investment Feasibility Analysis of Nickel Mining in Indonesia with Sensitivity Analysis and Monte Carlo

/in /by

Nickel is one of the metals commonly used in various industries. Indonesia is one of the countries that has the largest nickel reserves in the world. Nickel prices will be formed through an equilibrium mechanism between production supply and nickel demand. This study will analyse the relationship between nickel price formation, supply, and demand. Nickel prices will also affect the feasibility of nickel mining investment in Indonesia. The data used in this study consists of market data derived from historical reports of the last 5 – 12 years (2010 – 2022) and mining plan assumptions derived from benchmarks with similar industries. The methods used in this analysis are multivariate regression, discounted cash flow, sensitivity analysis, and Monte Carlo simulation. The results of the analysis that have been carried out show the relationship between nickel supply and demand with prices, with estimated nickel price projection ranging from $16,750 / Ton – to $18,927 / Ton. The factors that most influence the feasibility of mining investment are nickel price, sales realization, water content, contractor costs, and fuel costs. The risk of nickel mining investment in Indonesia based on Monte Carlo simulations is estimated at around 11.36%. This shows that nickel mining investment in Indonesia is still very attractive.

Stock Valuation and Financial Performance of Nickel Mining Company in Indonesia (Case Study: PT Vale Indonesia Tbk)

/in /by

Indonesia is home to 22% of the world’s nickel deposits, and its restriction on nickel ore exports since 2020 has resulted in significant changes to the supply chains of vital items such as electric vehicles and the stainless steel sector. Approximately 75% of nickel is used in the manufacturing of stainless steel, the most common use of nickel. However, nickel is also essential for the fabrication of electric vehicle (EV) battery cathodes, which are required for the shift to green energy. Current EV battery demand accounts for around 7% of worldwide output, but anticipated increases in EV demand will result in an exponential increase in nickel demand. The exponential increase in nickel demand led to volatility in global nickel prices. Volatility in global nickel prices is affecting companies that operate nickel mining businesses. PT Vale Indonesia Tbk (INCO) is listed on the Indonesia Stock Exchange as one of the nickel mining firms operating in the nickel mining business (IDX). The volatility of the global nickel price is both a breath of fresh air and a problem for the firm. INCO may also participate in and benefit from the rising worldwide demand for nickel in the foreseeable future.

The primary objective of this study is to evaluate the intrinsic value of a nickel mining company in order to assist investors in making decisions in the current market environment. Evaluation of financial performance over the last five years and projections for the next five years using absolute and relative valuation methodologies. The author suggests investors to purchase this stock using a risk-reward assessment suited to each investor’s circumstances and the potential return earned. Referring to the stock valuation evaluation, investors are recommended to purchase if the price of INCO falls below the range of IDR 6,051 to IDR 6,335. When the market price is inside and above the intended range, it is not advisable for an investor to purchase INCO.

Proposed a Design Company Performance Management System by Using Balanced Scorecard in a Nickel Mining Company (Case: PT Gema Kreasi Perdana)

/in /by

Indonesia is one of the countries that has the largest nickel reserves in the world. In the Asian region, Indonesia’s nickel laterite reserves are in the third position. Indonesia’s nickel reserves are around 800 thousand tons or about 30% of the world’s total nickel production, so that Indonesia has the potential to enjoy the demand for this stainless metal [7]. One of the companies that carry out nickel mining in Southeast Sulawesi Province is PT Gema Kreasi Perdana (GKP). As a newly established company, a variety of strategies are implemented to survive and maintain its corporate existence in the mining industry. The company needs a method for measuring performance in order to monitor and analyze company performance. Implementing a Performance Management System is one way that can be used (PMS). Balanced Scorecard (BSC) is the employed PMS in this investigation. BSC is a method for measuring the performance of a firm by bridging the gap between strategy and execution. Based on a literature review, focus group discussions (FGD), and interviews with expert practitioners in their respective fields, objective strategies are determined for each perspective. The aims and initiatives for key performance indicators (KPIs) are determined based on benchmarking with other businesses and company interviews. Data analysis and weighting from each perspective will be carried out using the Analytical Hierarchy Process (AHP) method. In addition to using goal strategies, the researchers cascaded the process from the Business Unit Level to the Individual Level and limited in the HRGA (Human Resource and General Affair) and Strategic Affair Division of PT Gema Kreasi Perdana. The cascading process is believed important to ensure that the company’s vision, mission, and strategy are communicated clearly to all employees. The cascading process is regarded important to ensure that the company’s vision, goal, and strategy are communicated clearly to each employee. This cascading produced multiple objective strategies and KPIs for HRGA and Strategic Affair Division of PT GKP. As suggestions for future research, it would be preferable for the research to cascade to all levels within each division in the company.

Features of Geological Structure and Mineragenic Specialization of Sheikhdzheyli-Zengiboba of the Sultan-Uvais Ridge Area

/in /by

The productive mineralization of the Sheikhdzheili-Zengiboba area is associated with metamorphogenic transformations of the rocks of the Urusai, Karauzyak, Kuyanchik, Sheikhdzheili suites, metamorphosed under conditions of green schist facies. The mineralized zones of the site are confined to narrow faults in the tectonic zones of the northeast and northwest directions. The main form of manifestation of gold-bearing mineralization is small steeply dipping veins, lenses, nests, non-extended systems of conformal and secant quartz veinlets containing dissemination of pyrite, arsenopyrite, chalcopyrite and pyrrhotite, which are represented by gold-arsenopyrite-pyrite, gold-arsenopyrite-chalcopyrite-pyrite natural type of ores.
