Abstract

The human resources aspect is the most important thing for companies, especially to achieve organizational goals, because the success or failure of an organization is greatly influenced by human factors as people who carry out the work. One of the targets of human resource management in the organizational management function concerns employee performance issues. Employees at the Sewing Department PT. Pan Brothers Tbk Boyolali has an unstable level of performance, which can affect the achievement of company goals. This research aims to explain the factors that can influence a person's performance, such as leadership style, work culture and physical work environment which can influence employee performance. The sample was obtained using a purposive sampling method, and 47 civil servant respondents were selected as the sample. Meanwhile, the data analysis used in this research includes: data quality testing, classical assumption testing, hypothesis testing and multiple regression analysis. The results of the partial significant test (t statistical test) from the research analysis and discussion show that; transactional leadership style, with a t value of 1,555, this value is smaller than t table 1,669. This explains that the Transactional Leadership variable has no effect on the Employee Performance variable. Work Culture, with a t value of 3,033, this value is greater than t table 1,669. This explains that the Work Culture variable has an influence on the Employee Performance variable. Physical Work Environment, with a t value of 2,467, this value is greater than t table 1,669. This explains that the Physical Work Environment variable has an influence on the Employee Performance variable. Meanwhile, the results of the simultaneous significant test (f test) show that Fcount 5,600 > Ftable 2,751 with a significance value of 0.002. So it can be concluded that the two independent variables, namely Transactional Leadership (X1), Work Culture (X2) and Physical Work Environment (X3) greatly influence the dependent variable, namely Employee Performance (Y) at PT. Pan Brothers, Tbk Boyolali.

Abstract

Coal mining activities often result in acid mine drainage (AMD), which can cause environmental pollution if not properly managed. This study aims to evaluate the potential use of fly ash from the Stream Power Plant (PLTU) Tenggarong to mitigate the impacts of AMD, specifically targeting iron (Fe), manganese (Mn), and pH parameters. Acid Mine drainage is formed when sulfide minerals oxidize, producing acidic compounds that can harm the environment. This research focuses on analyzing the ability of fly ash to adsorb iron and manganese from AMD solutions, as well its capability to increase solution pH. Based on the conducted research, the optimum pH value was achieved when using 10 grams and 15 grams of fly ash in the adsorption process. The optimum concentration of iron (Fe) was attained using 10 grams to 15 grams of fly ash, while for manganese (Mn), it was achieved with 20 grams to 25 grams of fly ash. The adsorption process using 25 grams of fly ash showed the highest efficiency in reducing iron (Fe) concentration by 93.78 % and manganese (Mn) concentration by 75.47 %.

Abstract

PT.XYZ is an automotive company that has been operational since 1970, with over 400 suppliers for key components such as Stoper A and Stoper B. Annually, Stoper A sells 151,000 units (valued at IDR 4.077 billion), while Stoper B reaches 300,000 units (valued at IDR 8.100 billion). This research focuses on analyzing and optimizing the supply chain for these components, using sales data from January to December 2022. The goal is to create stock and flow diagrams, analyze the supply chain system modeling, and propose optimal scenarios for demand fulfillment. The modeling results indicate that a strategy of adding a 20% safety stock to the average sales is highly effective in preventing lost sales without burdening suppliers with overtime. However, the potential for overstock needs to be monitored. Based on the analysis, the second scenario proposing the addition of safety stock is recommended due to its effectiveness in meeting demand and efficiently managing inventory. This scenario is deemed most suitable for PT. XYZ in maintaining a balanced supply without unnecessary surplus.

Abstract

This research aims to analyze the risk of work accidents at PT Sermani Steel Corporation using the Failure Mode Effect Analysis (FMEA) method. This method is applied to identify potential hazards in the production process of zinc coated steel, such as hollow, C channel, and battens. Data were collected through questionnaires, observations, and interviews, then processed to calculate the Risk Priority Number (RPN). The results showed that the highest risk was found in zinc machine production activities, with an RPN value of 321.6, mainly related to the risk of being cut by products or product debris. Based on Pareto and Fishbone Diagram analysis, the main causes of accidents are human, machine, method, and environmental factors. The conclusions emphasize the importance of OHS training, installation of signs and indicator lights on machines, and close supervision to minimize the risk of accidents. The recommendations provided are expected to reduce work accidents by 38% of the total accidents that occur in the production area.
