Abstract

This study aims to analyze Musculoskeletal Disorders (MSDs) complaints in shoe production workers at PT XYZ and evaluate work postures using the Posture Evaluation Index (PEI) approach. The methods used include data collection through direct observation, distribution of Cornell Musculoskeletal Discomfort Questionnaire (CMDQ), and posture assessment using OWAS, RULA, and REBA methods. The results showed that complaints most often occurred in the upper back, neck, and right shoulder, which were mostly caused by non-ergonomic work postures. The PEI assessment showed that the work section with the highest risk was the packing section, with a score of 2.7 indicating the need for immediate improvement. After improving the work posture according to ergonomic principles, the PEI score decreased to 1.6, indicating increased comfort and decreased risk of injury. This study emphasizes the importance of periodic ergonomic evaluations to improve work comfort and productivity.

Abstract

This study aims to determine the effect of music tempo on work productivity and the level of cognitive failure among employees in the fabrication division of PT. Adi Joyo Kusumo. Music is used as an intervention to address boredom and stress caused by monotonous work. This research employs the Cognitive Failure Questionnaire (CFQ) method distributed to 12 employees, and observations were made on production quantities over seven days under three conditions: without music, fast tempo music, and slow tempo music. The results indicate that fast tempo music yields the highest productivity level with a total production of 26 units, followed by the no music condition (23 units) and slow tempo music (21 units). Validity tests show that all CFQ items are valid, and reliability tests yield a Cronbach’s Alpha value of 0.921, indicating reliability. ANOVA tests show a significance value of 0.000 (p < 0.05) and an F value of 17.078, indicating a significant effect of music tempo on cognitive failure levels. Although fast tempo music can enhance work performance, the noise level reached 89 dB, disturbing other divisions. This study concludes that fast tempo music can be used as a productivity enhancement strategy, provided that noise levels are controlled to avoid negative impacts on other work environments.

Abstract

Persediaan yang efektif merupakan salah satu elemen penting dalam mendukung kelancaran operasional perusahaan. Penelitian ini bertujuan untuk mengoptimalkan manajemen stok material consumable di warehouse PT. Kaltim Methanol Industri melalui penerapan metode Economic Order quantity (EOQ) dan Min-Max Inventory. Metode EOQ digunakan untuk menentukan kuantitas pemesanan yang optimal guna meminimalkan total biaya persediaan, sedangkan Min-Max Inventory membantu dalam menetapkan batas minimum dan maksimum stok untuk mencegah kekurangan atau kelebihan persediaan. Penelitian ini menganalisis data historis konsumsi material, biaya pemesanan, dan biaya penyimpanan untuk menghitung parameter optimal. Hasil penelitian menunjukkan bahwa penerapan kombinasi kedua metode ini berhasil meningkatkan efisiensi pengelolaan stok, mengurangi frekuensi pemesanan, menentukan jumlah pesanan yang optimal, serta mengoptimalkan tingkat persediaan material consumable. Implementasi sistem ini memberikan dampak positif terhadap efektivitas operasional dan penghematan biaya perusahaan.Kata Kunci: Economic Order quantity, Min-Max Inventory, Persediaan.

Abstract

General Background: Occupational health and safety remains a critical concern in manufacturing operations where unrecognized hazards contribute to workplace accidents. Specific Background: In agricultural machinery production, the production department still encounters multiple hazards, limited supervision, and low compliance with safety standards despite the establishment of a dedicated safety unit. Knowledge Gap: Prior studies applying Hazard Identification, Risk Assessment, and Risk Control (HIRARC) predominantly focus on identification and assessment stages, with limited integration of root cause analysis for high and extreme risks. Aims: This study aims to systematically identify hazards, assess risk levels, and determine appropriate control measures through an integrated HIRARC and Fishbone approach. Results: The analysis identified 27 risk events, comprising 10 low, 8 medium, 8 high, and 1 extreme risk, with the most critical risk associated with crane-based material handling operations requiring immediate control prioritization. Root causes of high and extreme risks were linked to human, machine, method, material, and environmental factors. Novelty: The study introduces an integrated HIRARC–Fishbone framework to prioritize risk control while simultaneously identifying root causes in manufacturing processes. Implications: This approach provides a structured basis for prioritizing critical risks and supports systematic accident prevention strategies, contributing to improved occupational safety performance in industrial environments. Highlights: Twenty-seven hazard-related activities were classified into four risk categories. Crane-based material handling emerged as the most critical hazard source. Human-related factors dominated the root causes across high-risk scenarios. Keywords: Fishbone Diagram, HIRARC, Manufacturing Industry, Occupational Health and Safety

Abstract

Dalam upaya mewujudkan pembangunan perkotaan yang ramah lingkungan dan berkelanjutan, pemilihan metode konstruksi tidak dapat sembarangan. Beton pracetak dipilih karena lebih cepat dan efisien dibandingkan metode konvensional yang mengandalkan pengecoran di lokasi. Penelitian ini bertujuan untuk membandingkan waktu, biaya, dan mutu elemen struktur menggunakan metode konvensional dan pracetak. Metode yang digunakan adalah perhitungan volume pekerjaan, serta pemantauan siklus pengecoran kedua metode, serta hasil uji beton dan daftar cacat pekerjaan. Hasil penelitian ini adalah terdapat selisih biaya sebesar Rp 3.356.048.243 atau sekitar 8,64%, di mana metode pracetak menunjukkan biaya yang lebih tinggi dibandingkan metode konvensional. Dengan selisih waktu 57 hari, metode pracetak terbukti memberikan efisiensi waktu sekitar 35%. Ditemukan adanya selisih sebanyak 164 item, atau sekitar 32% lebih banyak cacat pada struktur pracetak dibandingkan dengan metode konvensional. Kesimpulan, Signifikansi, dan Implikasi dari penelitian ini adalah meskipun lebih cepat, kualitas pemasangan pada metode pracetak tetap perlu diperhatikan agar hasil akhir tetap memenuhi standar yang diharapkan.
