type: item
description: The physical work environment in the Aerosol Production Department of PT XYZ experienced problems related to excessive room temperatures reaching 37.3°C and chemical odor pollution caused by vapor recirculation from the coating oven process. These conditions potentially reduced operator comfort and concentration. This study aimed to analyze the effectiveness of the Kaizen approach through the Plan-Do-Check-Act (PDCA) cycle in controlling production room temperature and improving air quality. A quantitative descriptive method with an Action Research approach was employed. Problem identification and root cause analysis were conducted using the 7 QC Tools, particularly the Pareto Diagram and Fishbone Diagram. Improvement actions included the installation of turbine ventilators, aluminum foil roof insulation, and a 3-meter vertical exhaust ducting system. The results showed that the average room temperature decreased from 34.6°C to 27.4°C, representing a reduction of 7.2°C, while the peak daytime temperature decreased by 8.7°C and met the established threshold limit value. In addition, chemical odor pollution was completely eliminated. Therefore, the Kaizen-PDCA approach proved effective in improving the physical work environment sustainably.

Analisis Kinerja Produksi Untuk Peningkatan Output Menggunakan Theory Of Constraints Di Pt Xyz
type: item
description: Abstract. PT XYZ, a wooden furniture manufacturing company, served as the research site for this study which applied the Theory of Constraints (TOC) method to analyze production performance and identify bottlenecks. The company faces capacity imbalances between workstations, resulting in production targets that have not been achieved optimally. Data collection involved direct observation and interviews with related parties in the production area. The analysis was conducted by comparing the required capacity with the available capacity at each production workstation. The findings reveal that solid processing, machining, sanding, assembling, painting, and packing have sufficient available capacities to meet production requirements, thus categorized as non-bottleneck processes. In contrast, the panel processing station is identified as the main bottleneck due to its highest workload among all processes. By implementing the Theory of Constraints, the company can identify major constraints and establish improvement priorities to enhance production flow smoothness. It is expected that improvements in bottleneck processes will increase production efficiency, balance capacity among workstations, and support more optimal achievement of production targets.

type: item
description: Ketidaksesuaian kualitas pada proses assembly sepatu kulit kerap memicu siklus rework berulang yang menguras sumber daya waktu maupun biaya produksi secara signifikan. Penelitian ini mengkaji mekanisme pengendalian cacat yang diterapkan pada Product D-01 di Lini C PT XYZ, dengan menggunakan DMAIC sebagai kerangka perbaikan utama serta Pareto, P-Chart, Fishbone Diagram, 5 Whys, Failure Mode and Effects Analysis (FMEA), dan Cost of Quality (COQ) sebagai alat pendukung. Data primer bersumber dari catatan produksi internal perusahaan, pengamatan lapangan, dan wawancara terstruktur bersama pengawas produksi dan staf quality control. Pengukuran baseline menunjukkan bahwa Lini C menyumbang volume cacat paling tinggi di antara seluruh lini yang ada, dengan Product D-01 mencatat 10.487 pair cacat dari total output 80.387 pair, sehingga menghasilkan defect rate sebesar 13,05%. Distribusi Pareto mengidentifikasi wrinkle, incorrect colour, dan not straight sebagai tiga kategori cacat paling kritis. Penilaian FMEA menetapkan Risk Priority Number tertinggi sebesar 245 pada perilaku operator yang terburu-buru selama proses lasting dan brushing. Tindakan korektif mencakup pemasangan SOP visual, implementasi checklist QC pra-shift, verifikasi kondisi mesin secara rutin, dan penyediaan sampel referensi warna serta bentuk yang terstandar. Pemantauan selama dua periode berikutnya mengkonfirmasi penurunan defect rate secara bertahap menjadi 12,80% dan kemudian 11,65%, disertai penurunan estimasi biaya kegagalan internal dari Rp 2,36 juta menjadi Rp 1,86 juta per periode.

Pengaruh Jenis Laminasi terhadap Kuat Tarik dan Perubahan Warna pada Pressure sensitive label PE White
type: item
description: Pressure sensitive labels (PSLs) made of polyethylene (PE) white are widely used in the packaging industry due to their flexibility, moisture resistance, and ease of application on various substrates. This study aimed to examine the effect of glossy and matte lamination on the tensile strength and color difference (ΔE) of PE white PSLs. An experimental method was employed, with tensile testing conducted using a universal testing machine (UTM) in accordance with ASTM standards and color measurement performed using a spectrodensitometer based on the CIE Lab system. The samples were divided into three treatment groups, namely no lamination, glossy lamination, and matte lamination, with ink coverage controlled at two design conditions, full ink and minim ink. The results indicated that lamination type significantly affected both the mechanical and visual characteristics of the labels. In the tensile strength test, the highest mean value was obtained by one treatment group, indicating superior resistance to tensile loading. In terms of color stability, higher ΔE values indicated greater color change and lower lightfastness, whereas lower ΔE values reflected better color retention. Overall, the findings show that the combination of lamination type and ink coverage influences the performance of PE white PSLs in both mechanical strength and color stability.

Analisis Perbandingan Tingkat Kebisingan Kabin Pada Mitsubishi Destinator Varian Sunroof dan Non-Sunroof Menggunakan Sound Level Meter
type: item
description: This study aims to analyze and compare the cabin noise levels of the Mitsubishi Destinator Ultimate variant (sunroof) and Exceed variant (non-sunroof) under various driving speed conditions. Measurements were conducted using a Sound Level Meter inside the cabin at idle, 10, 30, 50, 70, 90, and 100 km/h. Results indicate that the Ultimate (sunroof) variant consistently produces higher noise levels than the Exceed (non-sunroof) variant across all speed variations. The largest noise difference was recorded at 100 km/h at 6.50 dB, while the smallest occurred at idle at 0.05 dB. Noise levels in both variants increased significantly with increasing speed, with the sunroof variant reaching 70.00 dB and the non-sunroof variant reaching 63.50 dB at 100 km/h. This difference is attributed to gaps and seals in the sunroof panel, which allow greater noise penetration from the external environment.

Enhancing Halal Supply Chain Resilience through Digital Traceability: A Multi-Stakeholder Perspective
type: item
description: The increasing complexity of global halal supply chains has created significant challenges in maintaining integrity, transparency, and resilience across interconnected stakeholders. Disruptions caused by technological limitations, information asymmetry, regulatory differences, and trust issues can threaten halal compliance and consumer confidence. This study aims to examine how digital traceability mechanisms contribute to enhancing halal supply chain resilience from a multi-stakeholder perspective. Using a qualitative conceptual approach based on an integrative literature review, this study synthesizes insights from halal supply chain management, digital transformation, organizational resilience, and industrial psychology. The findings indicate that digital traceability improves supply chain resilience through three key mechanisms: strengthening information transparency, increasing stakeholder trust, and facilitating collaborative decision-making. However, technological adoption alone is insufficient; successful implementation requires psychological readiness, organizational commitment, digital competency, and trust-based relationships among stakeholders. From an industrial psychology perspective, employee acceptance, perceived usefulness, organizational support, and cross-functional collaboration represent critical determinants influencing digital traceability effectiveness. This study contributes to the halal supply chain literature by integrating technological and behavioral perspectives, emphasizing that resilient halal ecosystems require alignment between digital infrastructure and human-centered organizational practices. The findings provide practical implications for halal industry managers, policymakers, and certification authorities in designing sustainable and adaptive halal supply chain systems.

Optimasi Rute Distribusi Dan Penentuan Jumlah Tenaga Kerja Kurir Di Umkm Kerupuk Mawar
type: item
description: This study aims to optimize the distribution routes and determine the ideal number of courier workforces at UMKM Kerupuk Mawar, an MSME facing inefficiencies in product delivery. The existing delivery system operates without structural planning, leading to long travel distances, high fuel consumption, and uneven driver workloads. To address these challenges, this research integrates the Saving Matrix method to optimize vehicle routing and the Full-Time Equivalent (FTE) method to evaluate and determine the optimal courier capacity based on actual workloads. Data were collected through direct observation, measuring delivery times, activities, and geographical coordinates of 25 customer locations. The results from the Saving Matrix analysis successfully reshaped the distribution network into optimal circular routes (ritase), reducing the total travel distance by 29.58% and decreasing monthly fuel costs by IDR 1,181,700. Concurrently, the FTE analysis revealed that the existing couriers experienced underload conditions due to unorganized scheduling. By restructuring the workforce based on FTE index projections, the company can operate efficiently with 5 optimized couriers, balancing workload distribution and minimizing idle time. In conclusion, combining routing optimization and workload-based workforce planning provides significant cost efficiency and operational balance for small and medium enterprises.

Defect Analysis of R8 Cover Products Using the Six Sigma Method at PT Amtek Engineering
type: item
description: Quality consistency is a critical requirement in automotive component manufacturing, particularly in precision stamping processes where visual conformity, product identification, and physical integrity directly influence customer acceptance. This study investigates quality defects in R8 Cover production at PT Amtek Engineering using the Six Sigma DMAIC (Define–Measure–Analyze–Improve–Control) framework. A descriptive quantitative and observational approach was employed using production and reject records collected from 5–17 May 2024. The Define phase utilized SIPOC and Critical-to-Quality (CTQ) mapping to identify key quality characteristics. Process capability was evaluated through Defect per Unit (DPU), Defect per Opportunity (DPO), Defect per Million Opportunities (DPMO), process yield, and sigma level measurements. Pareto analysis and fishbone diagrams were applied to determine dominant defect categories and their potential root causes. The results indicate that 82,843 units were produced with 4,533 rejected units, resulting in a DPU of 0.0547, a DPO of 0.0109, a DPMO of approximately 10,900, a process yield of 98.91%, and a sigma level of 3.8. Missing and damaged identification was identified as the most significant defect, contributing 33% of total defects, followed by missing lettering at 23%. Root-cause analysis revealed that defect occurrence was associated with operator practices, machine and tooling conditions, inspection procedures, material conformity, and workplace environment. The study proposes improvement actions focused on setup verification, preventive maintenance, tooling management, inspection standardization, operator competency development, and incoming material control. These findings provide an empirical basis for enhancing process capability and strengthening quality assurance in precision stamping operations.

CPM analysis was conducted using POM-QM for Windows to determine the critical path and project duration, while Resource Leveling was performed using Microsoft Project to optimize operator allocation. The results showed that the optimal project duration was 139.66 hours, with the critical path consisting of Frame 1+2+Support Frame and Assy MS Emboss activities. After implementing Resource Leveling, the maximum operator requirement decreased from 17 to 10 operators, the Coefficient of Variation (CV) decreased from 58.35% to 39.10%, and the Standard Deviation decreased from 4.96 to 2.67 without extending project duration. These findings demonstrate that the integration of CPM and Resource Leveling improves scheduling efficiency and supports balanced workload distribution in the PM11 Emboss Machine production process at PT XYZ.

Analisis Postur dan Perbaikan Metode Kerja dengan Metode Rapid Upper Limb Assessment (RULA) pada Industri Minyak Goreng
type: item
description: The manual loading of finished goods in the cooking oil industry has the potential to cause unergonomic work postures and musculoskeletal disorders (MSDs). This study aims to analyze the work posture of loading workers at CV. OASE using the Rapid Upper Limb Assessment (RULA) method, identify body complaints through the Nordic Body Map (NBM), and provide suggestions for ergonomic work improvements. Data were collected through observation, interviews, posture documentation, NBM questionnaires for 12 workers, and posture angle measurements using the Angle Meter 360 application for 4 workers. The results showed that all workers obtained a final RULA score of 7, including high risk and requiring immediate improvement. The NBM results showed dominant complaints in the waist with a score of 44 and the lower neck with a score of 42, including very high risk. The contributing factors were a bent posture of more than 60°, a carton load of more than 10 kg, and repeated lifting. Suggested improvements include the use of an adjustable conveyor belt so that the carton position is parallel to the worker's waist. The RULA simulation showed a score decrease from 7 to 6, so the risk changed from high to medium. These improvements are expected to reduce MSD complaints and increase the comfort and productivity of loading workers.

Analisis K3 pada Sistem Kerja Menggunakan Metode Chi Square
type: item
description: Usaha mikro ritel, khususnya Toko Madura, memainkan peran penting dalam memenuhi kebutuhan masyarakat. Namun, aktivitas kerja yang didominasi oleh durasi kerja yang panjang, beban kerja fisik, dan postur kerja yang tidak ergonomis berpotensi menyebabkan keluhan kesehatan pada pekerja. Penelitian ini bertujuan untuk menganalisis hubungan antara durasi kerja, beban kerja fisik, dan postur tubuh dengan keluhan kesehatan serta mendeskripsikan implementasi Keselamatan dan Kesehatan Kerja (K3) berbasis ergonomi di usaha mikro ritel. Penelitian ini menggunakan pendekatan kuantitatif deskriptif dengan pengumpulan data melalui observasi dan kuesioner dari 60 responden yang bekerja di usaha mikro ritel di Surabaya, Mojokerto, dan Gresik. Analisis data dilakukan menggunakan uji Chi-Square untuk menguji hubungan antar variabel kategorikal. Hasil penelitian menunjukkan bahwa semua variabel memiliki hubungan yang signifikan dengan keluhan kesehatan, yaitu durasi kerja (p = 0,020), beban kerja fisik (p < 0,001), dan postur tubuh (p < 0,001), sehingga hipotesis alternatif diterima. Temuan ini menunjukkan bahwa semakin lama durasi kerja, semakin tinggi beban kerja fisik, dan semakin tidak ergonomis postur kerja, semakin besar risiko keluhan kesehatan pada pekerja. Implikasi dari penelitian ini adalah perlunya menerapkan manajemen K3 berbasis ergonomi melalui pengaturan jam kerja, penyediaan waktu istirahat yang memadai, pengendalian beban kerja, perbaikan postur kerja, penyusunan SOP, dan pelaksanaan pelatihan K3 secara berkala untuk meningkatkan kesehatan, keselamatan, dan produktivitas pekerja usaha mikro ritel.

Analisis Waste pada Produksi Arm Sepeda Motor Menggunakan Metode 5S dan Value Stream Mapping di PT XYZ
type: item
description: The development of the manufacturing industry at the Small and Medium Enterprises (SMEs) scale in Indonesia demands increased efficiency in the production process to be competitive, but various wastes are still found, especially in non-value-added activities. This study aims to identify, analyze, and minimize waste in the production process of motorcycle Arm spare parts at PT. XYZ. The method used is a Lean Manufacturing approach through the application of Value Stream Mapping (VSM) and 5S (Seiri, Seiton, Seiso, Seiketsu, Shitsuke). Data collection was carried out through direct observation, interviews, and questionnaires to identify the dominant types of waste using VALSAT (Value Stream Analysis Tools) weighting. The results showed that the main waste that occurred was movement and transportation caused by manual cleaning processes, suboptimal layouts, and inefficient material flow. Current State Mapping analysis showed a total waiting time of 4322 seconds, with activities that still contain waste. After the proposed improvements through Future State Mapping and the implementation of 5S, there was an increase in efficiency with a waiting time of 4260 seconds and an improvement in the condition of the work area to be neater, more organized, and safer. The conclusion of this study shows that the integration of VSM and 5S methods is effective in reducing waste, improving process flow, and increasing productivity and work efficiency in the metal SME industry.

Analisis Perbaikan Kualitas Produk Besi Beton Ulir dengan Pendekatan DMAIC dan Poka Yoke di PT X
type: item
description: This study aims to analyse the defect rate of threaded reinforcing bars, identify the dominant defects, determine Six Sigma capability, and design conceptual improvements based on Poka Yoke. The method used is Six Sigma with the DMAIC approach, combined with the Poka Yoke concept, supported by observational data, interviews, and historical data collected over a 15-day period. The results of the study indicate that the production process is not yet stable, with an average value of 3.96 Sigma and a Defects Per Million Opportunities (DPMO) of 6,831.37. A Pareto analysis identified dents (74.25 per cent) and tears (15.60 per cent) as the dominant defects. The FMEA evaluation found that the root cause with the highest priority was the absence of machine initial setup records (RPN 392) and parameter sheets (RPN 343). As a solution, it is proposed to implement Visual and Administrative Poka-Yoke measures via a One-Point Lesson (OPL) board to prevent ‘blind setup’, as well as to make the completion of check sheets mandatory. This proposal is projected to reduce the RPN for tear defects to 128 and for dent defects to 112, which will subsequently be formalised in Standard Operating Procedures (SOPs).

Penerapan Metode House Of Risk (HOR) dalam Upaya Mengurangi Potensi Kecelakaan Kerja di Area Produksi Gasket
type: item
description: 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.

Perancangan Sistem Kanban dan 5S sebagai Upaya Pengurangan Waste Overproduction dan Waste Inventory pada UKM Logam
type: item
description: This study addresses a metal-component SME producing motorcycle rear brake pedals and rings, which faces two primary Waste problems: overproduction Waste resulting in Work-in-process (WIP) accumulation of 31,860 units/day across 16 workstations, and inventory Waste caused by a finished-goods warehouse lacking a storage layout system, storage racks, or clear visual markers. This research aims to design a kanban system and propose 5S improvements as an integrated solution to address both problems. The method used is a quantitative descriptive approach with a case study using February 2026 production data. The kanban system design results show that each workstation requires 3 production kanban cards (P-Kanban) and 3 withdrawal kanban cards (W-Kanban), with container capacities varying across processes. Implementation of the kanban system was able to reduce average WIP by 70% from the initial condition. Meanwhile, the 5S checklist assessment results show an average achievement of 46.7%, with the Seiton, Seiketsu, and Shitsuke phases identified as improvement priorities, each achieving 33.3%. The proposed 5S improvements include the procurement of tiered storage racks with a color-coding system, product zoning, preparation of storage SOPs, and periodic internal audits.

Evaluasi Kinerja Navigasi Inspeksi Melingkar Otonom Berbasis Finite State Machine pada UAV dengan Variasi Jarak di Webots
type: item
description: Autonomous aerial inspection requires reliable navigation mechanisms to execute sequential flight operations while maintaining trajectory accuracy and returning to the initial position. This study evaluates a Finite State Machine (FSM)-based autonomous circular inspection navigation system implemented in the Webots simulation environment. The proposed navigation system consists of sequential states including takeoff, forward navigation, hovering, circular inspection, return navigation, and landing. The effect of inspection distance on navigation performance was investigated using five target-radius configurations of 3, 5, 7, 10, and 15 m, with three repetitions for each configuration. Performance was evaluated based on mission completion time, altitude root mean square error (RMSE), circular trajectory radius RMSE, yaw RMSE, and return-to-home (RTH) error. The results show that increasing the inspection radius leads to longer mission completion times, ranging from 88.61 s at 3 m to 350.54 s at 15 m. In contrast, altitude RMSE, radius RMSE, and yaw RMSE generally decrease as the inspection radius increases, with the lowest values obtained at 15 m of 0.1230 m, 0.1830 m, and 0.1806 rad, respectively. The RTH error exhibits a non-monotonic response, with the lowest value of 0.1615 m obtained at a 5 m inspection radius. These results indicate that inspection distance affects different aspects of autonomous navigation performance, particularly the trade-off between mission duration and trajectory-tracking accuracy. The findings demonstrate the feasibility of FSM-based autonomous circular inspection navigation in Webots and provide a simulation-based baseline for further robustness evaluation and real-world implementation.

Prioritizing Supply Chain Risks and Product Defects in an Abon SME: A Sequential House of Risk and Six Sigma Analysis
type: item
description: Small food-processing firms often manage demand volatility, limited capacity, supplier dependence, and product-quality problems through informal decisions. This study prioritizes supply-chain risks and product defects in a Yogyakarta-based abon (seasoned shredded-meat) small and medium-sized enterprise using a sequential Supply Chain Operations Reference, House of Risk, and Six Sigma analysis. The dataset comprised a 22-event and 36-agent risk register, 24 proposed mitigation actions, and operational records for 52,000 units with 1,860 product returns from September 2024 to February 2025. House of Risk phase 1 showed that 15 agents accounted for 81.34% of aggregate risk potential. House of Risk phase 2 identified 10 actions accounting for 81.13% of cumulative effectiveness-to-difficulty, led by production-capacity collaboration, a structured defect-reduction program, worker supervision, retraining, and daily capacity control. The return proportion was 3.58%. Based on six recorded defect opportunities per unit, the corrected aggregate performance was 5,961.54 defects per million opportunities and a sigma level of 4.014. A provisional p-chart showed three special-cause signals, while deflated or punctured packaging was the largest defect category at 24.30%. The analysis supports an integrated action portfolio covering capacity, workforce, standard operating procedures, maintenance, supplier backup, and packaging inspection. Because no post-intervention observations were available, the findings establish priorities and a baseline rather than verified improvement effects.
