Abstract

Occupational Safety and Health (K3) is an important aspect in protecting workers from potential accidents and health problems arising from work activities, including in the administrative sector, which is often considered low-risk. However, the Human Resources (HR) Department at PT Micro Madani Institute (MMI) Solo Branch still found several potential hazards and work risks that have not been optimally identified. This study aims to apply the Hazard and Operability Study (HAZOPS) and Job Safety Analysis (JSA) methods to identify and mitigate hazards and work accident risks in the HR Department's activities at PT Micro Madani Institute (MMI) Solo Branch. The research method is a qualitative study with a descriptive approach through observation and interviews. Risk analysis used the JSA and HAZOPS methods. The results of the study show that the application of the HAZOPS method in five sections of the HR Department successfully identified 53 potential hazards and risks, consisting of 12 extreme risks, 23 high risks, 15 moderate risks, and 3 low risks with the Employee Training and Development section as the section with the largest number of risks. Meanwhile, the application of the JSA method also identified 53 potential hazards and risks from 19 work activities. The dominant risks stem from non-ergonomic work postures, prolonged sitting, intensive computer use, and high workloads. This study concludes that the JSA and HAZOPS methods are effective in identifying potential occupational hazards and risks and can serve as the basis for control efforts to minimize workplace accidents and improve OHS implementation in the HR Department.

Abstract

Ineffective spare part inventory planning may lead to supply delays and reduced compliance with lead time supply key performance indicators (KPIs). This study aims to implement the Collaborative Planning, Forecasting, and Replenishment (CPFR) method in spare part inventory planning at PT XYZ and to compare lead time supply performance before and after the implementation of the CPFR method. This research utilizes spare part usage data from January to June 2025, focusing on fast-moving spare parts. Demand forecasting is conducted using an error forecasting approach with the moving average method. Forecast accuracy is evaluated using the Mean Absolute Deviation (MAD) and Mean Absolute Percentage Error (MAPE). Furthermore, inventory planning is carried out through the calculation of safety stock and reorder point (ROP) as the basis for determining replenishment decisions. The results indicate that the simulated implementation of the CPFR method provides a more structured and anticipative inventory planning process. The comparison of performance before and after the application of CPFR shows an improvement in lead time supply compliance with the established KPIs. Therefore, the CPFR method has the potential to support improved spare part inventory planning performance at PT XYZ.

Abstract

Occupational safety and health (OHS) is a crucial aspect that must be considered in every industry, including production environments involving heavy machinery and complex processes, which are often the site of workplace accidents. OHS analysis is crucial for ensuring worker safety and security, as well as identifying areas for improvement. This study aims to analyze the implementation of occupational safety and health (OHS) in the production area of PT Gama Steel Solo using the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) method. The results indicate that across seven main types of work in the production area, 34 potential hazards were identified, with 35 risks classified by risk level: 3 low risks, 9 moderate risks, 14 high risks, and 9 extreme risks. Based on the HIRARC analysis, several recommended risk control measures include engineering controls, administrative controls, and the use of personal protective equipment (PPE) in accordance with established standards. This study concludes that the HIRARC approach is effective in supporting companies to systematically identify hazards, conduct risk assessments, and provide a basis for decision-making/control recommendations to improve production safety.

Abstract

Penelitian ini bertujuan membandingkan efektivitas dua pendekatan hibrida, yaitu K-Means Clustering dengan metode Weighted Product (WP) dan Simple Additive Weighting (SAW), dalam pemetaan potensi wisata di Indonesia pada konteks pasca-pandemi. Data penelitian berasal dari 456 destinasi wisata, dengan 40 data terpilih yang digunakan dalam proses analisis berdasarkan kelengkapan dan konsistensi atribut. Tahapan penelitian meliputi pra-pemrosesan data, klasterisasi menggunakan algoritma K-Means, serta perankingan hasil klaster dengan metode WP dan SAW. Evaluasi kualitas klaster dilakukan menggunakan Silhouette Coefficient. Hasil penelitian menunjukkan bahwa kombinasi K-Means + WP menghasilkan nilai Silhouette sebesar 0,62, lebih tinggi dibandingkan K-Means + SAW sebesar 0,59, yang mengindikasikan pemisahan klaster yang lebih baik. Temuan ini menunjukkan bahwa pendekatan multiplikatif pada WP lebih efektif dalam mempertegas perbedaan karakteristik antar klaster, sehingga dapat digunakan sebagai metode pendukung pengambilan keputusan dalam pemetaan potensi wisata pasca-pandemi.   Abstract This study aims to compare the effectiveness of two hybrid approaches, namely K-Means Clustering with the Weighted Product (WP) method and Simple Additive Weighting (SAW), in mapping tourism potential in Indonesia in the post-pandemic context. The research data comes from 456 tourist destinations, with 40 selected data used in the analysis process based on the completeness and consistency of attributes. The research stages include data pre-processing, clustering using the K-Means algorithm, and ranking the cluster results using the WP and SAW methods. Cluster quality evaluation was carried out using the Silhouette Coefficient. The results show that the combination of K-Means + WP produces a Silhouette value of 0.62, higher than K-Means + SAW at 0.59, indicating better cluster separation. These findings indicate that the multiplicative approach in WP is more effective in emphasizing the differences in characteristics between clusters, so it can be used as a decision-support method in mapping post-pandemic tourism potential.
