Abstract

Work accidents are not just a single event but occur through a series of interrelated causes. The main source of accidents is the existence of unsafe actions that refer to worker behavior and unsafe conditions that refer to the work environment. The approach that can be used to prevent work accidents in the work environment is the implementation of the 5S standard through the Plan Do Check Action (PDCA) methodology. The implementation of 5S is carried out in stages and systematically starting from planning, implementation, checking, and continual improvement of each 5S element. Each of the five stages is important and should be taken seriously and handled separately and sequentially. The initial three stages are operational; the fourth phase preserves the state established in the first three phases; and the fifth phase aids in our efforts to improve things continuously. Improved working conditions and an accident-free workplace can result from a better understanding of the 5S idea and how it relates to the safety management system. This will increase employee satisfaction in industrial organizations.

Abstract

The palm oil industry is a strategic sector that plays a significant role in foreign exchange earnings and national employment, but is highly vulnerable to disaster risks, both from natural (floods, fires) and technical (machine breakdowns, supply chain disruptions) factors. This study develops an industrial engineering-based disaster management framework by integrating Monte Carlo Simulation to estimate economic losses and Survival Analysis (Kaplan–Meier and Log-Rank Test) to assess the operational resilience of palm oil mills. The simulation results show an average annual loss of IDR 3.87 billion, with a 95% VaR of IDR 8.97 billion and a 95% CVaR of IDR 11.25 billion. Factors such as preventive maintenance, the location of the mill in a flood-prone area, and the availability of backup power sources significantly influence post-disaster recovery time. This study provides a quantitative basis for the allocation of financial risk reserves and strategic recommendations to improve the operational resilience of the palm oil industry to disaster uncertainty.

Abstract

Proses pengolahan air limbah berminyak (oily water treatment process) di sektor industri migas memiliki variabilitas yang tinggi, sehingga memerlukan metode pemantauan yang peka terhadap perubahan kecil proses. Penelitian ini bertujuan untuk mengevaluasi stabilitas dan kapabilitas proses oily water treatment di PT. Pertamina Hulu Mahakam dengan menggunakan metode statistik EWMA (Exponentially Weighted Moving Average), CUSUM (Cumulative Sum),dan analisis kapabilitas proses non parametrik. Data hasil uji kadar minyak selama periode agustus hingga oktober 2025 dianalisis menggunakan software Minitab 20.3. Hasil uji normalitas Anderson Darling menunjukkan data tidak terdistribusi normal (p 0,005). Analisis EWMA dan CUSUM mendeteksi dua periode out of control (sampel 10-37 dan 64-82). Nilai Ppk sebesar 1,90 menunjukkan kinerja proses sangat baik dalam memenuhi standar baku mutu Permen Lingkungan hidup No.19/2010 yaitu dibawah 50 ppm. Hasil penelitian menekankan pentingnya implementasi peta kendali untuk pemantauan mutu air limbah secara berkelanjutan.Kata kunci: EWMA, CUSUM, kapabilitas proses, industri migas
