Abstract

Proses produksi krimer bubuk memiliki karakteristik bahaya yang kompleks karena melibatkan bahan berbentuk serbuk halus, mesin bertekanan, temperatur tinggi, bahan kimia pembersih, perpindahan material, dan aktivitas manual berulang. Kondisi tersebut menuntut pemetaan risiko yang tidak hanya menilai kejadian kecelakaan, tetapi juga memprioritaskan penyebab yang mampu memicu beberapa kejadian sekaligus. Penelitian ini bertujuan mengidentifikasi kejadian dan agen risiko keselamatan dan kesehatan kerja, menentukan agen risiko prioritas, serta menyusun urutan strategi mitigasi pada proses produksi PT. XYZ. Penelitian menggunakan studi kasus deskriptif dengan data kualitatif dan kuantitatif. Data dikumpulkan melalui observasi, wawancara, dan kuesioner terhadap 25 responden yang dipilih secara purposif dari area penerimaan bahan, pencampuran, pengeringan semprot, produksi, pengemasan, laboratorium pengendalian mutu, dan fungsi keselamatan kerja. Analisis dilakukan menggunakan House of Risk dua fase. Hasil penelitian mengidentifikasi 16 kejadian risiko dan 16 agen risiko. Agen dengan Aggregate Risk Potential tertinggi adalah paparan debu halus bahan baku dengan nilai 470, diikuti sumber percikan dari gumpalan krimer hangus dengan nilai 369. Sepuluh agen prioritas menyumbang 87,88% dari total potensi risiko agregat. Pada fase mitigasi, prosedur Clean as You Go memperoleh nilai Effectiveness to Difficulty tertinggi sebesar 3.033, disusul penggunaan alat pelindung diri lengkap sebesar 1.896 dan pelatihan pengangkatan manual sebesar 1.611. Temuan menunjukkan bahwa pengendalian segera berbasis kebersihan area dan kepatuhan pekerja perlu dipadukan dengan investasi rekayasa berupa pengendalian debu dan proteksi kebakaran. Pendekatan bertahap tersebut memberikan dasar operasional bagi perusahaan untuk mengalokasikan sumber daya keselamatan secara lebih terarah.

Abstract

Distribution channels have an important meaning for achieving company success in the field of marketing so that company management is required to always be responsive and able to adapt to environmental changes. Input and output data processing is done by giving weights to the input and output using the DEA CCR primal model by maximizing the input-oriented-based objective function. The results of processing the efficiency scale show the relative efficiency level of the scale of each DMU in the company. The efficiency scale is obtained through the formulation of the DEA CCR primal model between each DMU input and output. If the DMU gets an input and output efficiency value of less than 100%, then the DMU is said to be relatively inefficient. Meanwhile, if the efficient value is equal to 100%, then the DMU is said to be relatively efficient. Of the 5 distribution cities, Sidoarjo, PaluKendari, Bandung and Lamongan which were analyzed, there were 2 cities that were inefficient or experiencing waste in their input and output variables, so the company needed to reorganize the level of use of inputs and outputs it achieved and utilize them optimally to get output that is optimal. targeted.

Abstract

In an era where digital transformation dictates the survival of technology firms, selecting the optimal branch location is no longer a peripheral decision it is a strategic imperative. This study offers a powerful yet practical application of the Analytic Hierarchy Process (AHP) to evaluate potential expansion sites for a mid-sized software development company in Indonesia. By integrating expert judgments with location-specific criteria such as talent availability, infrastructure reliability, ecosystem proximity, and cost efficiency, the AHP model provides a structured, transparent, and replicable framework for decision-making. The results clearly identify Location A—an urban tech hub near major IT universities as the most strategic choice, significantly outperforming other alternatives. More than just a location ranking, this model demonstrates how conventional decision-making in software enterprise expansion can be elevated through applied analytical thinking. The study also proves that even without high-end analytics platforms, decision models built in common tools like Excel can yield robust and scalable insights. These findings carry immediate relevance for technology firms, policy planners, and academic researchers who seek to align operational expansion with long-term innovation and productivity outcomes in knowledge-based industries.

Abstract

This study aims to identify the potential risk of work accidents, determine the main causative factors, and develop risk mitigation strategies using the House of Risk (HOR) method in the gasket production area at PT XY. This research is motivated by the high potential for work accidents caused by the use of production machines, especially press machines that are not equipped with safety systems, as well as the implementation of risk management that still needs to be improved. The research uses a quantitative descriptive method by collecting data through direct observation and interviews with parties involved in the production process. The analysis was carried out using HOR Phase I to identify and determine the priority of risk agents based on the Aggregate Risk Potential (ARP) value, then continued with HOR Phase II to determine the most effective mitigation actions. The results of the study showed that there were 10 risk events and 14 risk agents that had the potential to cause work accidents. The main causative factors include high production targets, reduced operator concentration, machines without safety guards, non-compliance with SOPs, less than optimal preventive maintenance, damaged electrical cables, and inconsistent use of personal protective equipment (PPE). Prioritized mitigation strategies include increasing compliance with the use of PPE, implementing regular preventive maintenance, strengthening the implementation of SOPs through routine inspections, Occupational Safety and Health (K3) training, implementing the 5R/5S program, and installing safety sensors on press machines. The application of the HOR method provides a systematic approach in determining risk control priorities so that it can improve work safety in the production area.
