Abstract

PT. Nusa Palapa Gemilang merupakan sebuah perusahaan yang bergerak di industri pupuk NPK dan non NPK. Berdasarkan hasil observasi didapatkan beberapa potensi bahaya kerja, salah satunya adalah karena kurangnya kesadaran pekerja mengenai keselamatan dan kesehatan kerja (K3). Penelitian ini bertujuan untuk mengidentifikasi potensi kerja untuk mengantisipasi kecelakaan kerja. Penelitian ini menggunakan Hazard and Operability Study (HAZOP) untuk menganalisis potensi hazard di unit produksi NPK 1. Berdasarkan klasifikasi hazard setelah dilakukan penilaian risiko, hasil penilaian risiko menunjukkan sebanyak 95% potensi hazard merupakan hazard tingkat risiko tinggi (high) dan sebanyak 5% potensi Hazard merupakan hazard risiko sedang (moderate). Selain itu, ditemukan sebanyak 14 potensi hazard yang dapat diklasifikasikan menjadi empat tipe hazard yaitu sikap kerja, prosedur kerja, tempat kerja, dan kondisi lingkungan kerja. Rekomendasi yang diberikan berdasarkan klasifikasi bahaya berupa himbauan pekerja untuk menggunakan APD berupa masker, helmet, safety spectacles, dan sepatu safety. Selain itu, diperlukan rambu-rambu seperti rambu wajib penggunaan APD, rambu bahaya forklif, dan rambu lantai licin sebagai peringatan kepada pekerja bahwa terdapat risiko bahaya saat berada di tempat kerja, sehingga K3 di tempat kerja dapat ditingkatkan dan dapat memiminimalkan kecelakaan kerja.

Abstract

Inefficiencies in temperature-controlled raw material warehouses, especially in the Fast-Moving Consumer Goods (FMCG) industry, can hinder production continuity and escalate operational costs. PT. XYZ, a leading cosmetic manufacturer, currently uses a Dedicated Storage system that fails to consider material movement frequency, resulting in limited storage slots, high material handling costs, and ineffective retrieval processes. To overcome these challenges, this study applied the Class-Based Storage (CBS) method by classifying materials into A (fast-moving), B (medium-moving), and C (slow-moving) categories based on their movement frequency. The contribution of this research lies in integrating CBS with the nearest location principle and simulation modeling to provide a structured solution for warehouse layout optimization. A quantitative approach was used by collecting outbound raw material data from January to December 2024, analyzing material movement frequency, and calculating material handling costs. The redesign of the warehouse layout considered the frequency-based classification and used AnyLogic software to simulate the proposed configuration. The analysis also involved calculating rectilinear distances and estimating handling costs based on operator and equipment expenses. The results showed that the proposed CBS-based layout reduced the total travel distance by 27.55% and decreased daily material handling costs by 28.67%. Additionally, high-frequency materials were positioned closer to the input/output points, improving accessibility and retrieval speed. The simulation confirmed increased warehouse efficiency, better space utilization, and reduced operator workload. In conclusion, the implementation of the CBS method in warehouse layout design significantly improved operational performance and reduced logistics costs. This study serves as a reference for companies managing temperature-sensitive inventory and provides a foundation for future research incorporating real-time inventory tracking and dynamic slotting systems.

Abstract

Nurses working in critical care units face substantial mental workload and occupational stress, yet most prior studies rely on a single subjective or objective measurement approach. This study examined the mental workload and occupational stress of Intensive Care Unit (ICU) and Emergency Department (IGD) nurses at RSUI Cawas Klaten, Indonesia, and validated subjective instruments against physiological indicators. Using a quantitative descriptive correlational design, data were collected from all 27 ICU and IGD nurses (total sampling) using the NASA Task Load Index (NASA-TLX), the Expanded Nursing Stress Scale (ENSS), and an Apple Watch SE Generation 2 smartwatch recording Heart Rate (HR) and Heart Rate Variability (HRV) across three phases: rest, work, and questionnaire completion. Results showed a High mental workload (mean Weighted Workload = 54.67) dominated by the Effort dimension, and an overall Low Stress level (mean ENSS = 1.95) that approached the Moderate Stress threshold, led by treatment uncertainty and patient/family related stressors. Pearson correlation revealed a significant positive relationship between ENSS and HRV during work (r = 0.630, p < 0.001) and between NASA-TLX and HR during work (r = 0.468, p = 0.014), whereas post work measurements showed no significant association. These findings confirm that HR and HRV recorded during active work, rather than after work, are valid physiological indicators for cross validating subjective workload and stress instruments among critical care nurses.

Abstract

Engineering laboratories combine high-energy machinery, live circuits, pressurised fluids and open flames with novice student operators, yet occupational health and safety in Indonesian higher education is still managed largely through academic rather than risk-based instruments. This study applies Hazard Identification, Risk Assessment and Risk Control (HIRARC) to six practicum laboratories of the Department of Mechanical and Industrial Engineering, Universitas Tidar, using the practicum activity rather than the room as the unit of analysis. Hazards were identified through direct observation and document review and scored by an assessor panel on a 5 x 5 matrix with predefined severity and likelihood criteria. Three main findings emerge. First, the 27 activity-level hazards are dominated by mechanical sources, and nearly half of the activities (44%) are high risk before control. Second, risk profiles differ between laboratories: the machining-intensive Production Process, Welding and CNC laboratories carry the highest mean risk, while the single most severe activity is CNC operation with a running spindle, so mean-based and peak-based rankings point to different priorities. Third, combined engineering and administrative controls, each mapped to the Indonesian regulation that requires it, are expected by the assessor panel to bring every activity to the low band, an estimated mean reduction of 58.5%; this is a prospective panel estimate, not a result measured after implementation. The study contributes an activity-based, regulation-linked risk register that allows laboratories with different energy profiles to be compared on one scale and to be prioritised for safety investment.

Abstract

Labor-intensive manual production lines often lose efficiency through non-value-added (NVA) motion and uneven operator workload, yet these two problems are usually addressed separately. This study aims to design a framework whose main contribution is the integration of waste identification, work-method redesign, and workload balancing within a single procedure. Value Stream Mapping (VSM) maps the production flow and locates waste, the Eliminate–Combine–Rearrange–Simplify (ECRS) principle redesigns the work sequence, and a full-time-equivalent (FTE) workload analysis reallocates operators across stations. Standard times were established using the Westinghouse performance rating and ILO allowances. The framework was applied to a barecore production line in the furniture sector. The proposed redesign reduces the number of activities from 10 to 8 with the same workforce of 32 operators, and is estimated to cut total production time per sheet by 84.3 s (9.05%), from 931.15 to 846.86 s. The maximum operator workload is estimated to decrease from 0.81 to 0.77, and the workload range between the most- and least-loaded stations to narrow from 0.68 to 0.64, with no station exceeding the FTE limit of 1. These results indicate that the estimated efficiency gain comes from removing waste rather than from overloading operators. The framework offers a low-cost, repeatable diagnostic-and-redesign procedure and has potential for application to other labor-intensive manual production environments, subject to further validation across different products and layouts.
