Abstract

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).

Abstract

The design and implementation of a Direct Current (DC)-based Solar-Powered Street Lighting System (PJUTS) represents an alternative solution to improve energy efficiency while promoting the utilization of renewable energy on university campuses. This study aims to design and implement a DC-based solar-powered street lighting system for the campus environment of Soerjo University, Ngawi. The research methodology included field observation, system design, component selection, installation, and performance testing of the proposed system. The implemented system consists of a 20 Wp solar panel, a 12 V 7.5 Ah VRLA battery, a 10 A solar charge controller, and a 20 W DC LED lamp. The solar panel converts solar energy into electrical energy during the daytime, which is stored in the battery and automatically utilized to power the lighting system at night through the controller. The total cost of designing and installing the system was IDR 1,460,000. The results indicate that the system operates effectively and provides adequate illumination for the campus environment according to the planned specifications. System performance is influenced by several technical factors, including installation location, pole height, solar panel tilt angle, cable installation quality, and protection system suitability. Potential problems include short circuits, cable damage, and component performance degradation due to environmental conditions. Therefore, the use of standardized components and regular maintenance is essential to ensure system reliability, efficiency, and service life. This study is expected to contribute to the development of efficient, economical, and environmentally friendly solar-powered street lighting systems, particularly in educational institutions.

Abstract

Product quality is a key factor in improving the competitiveness of manufacturing companies. PT. X, a spunbond fabric manufacturer, continues to face product defects that affect production quality. This study aims to identify Critical to Quality (CTQ) characteristics, determine the dominant defect types, measure process capability using the Six Sigma method, and propose quality improvement recommendations. The study used all production and defect data as the population, with six months of production data (May–October 2025) selected through purposive sampling based on data availability and completeness. Data were analyzed using the Six Sigma approach, including CTQ analysis, Pareto diagrams, P-Charts, Defects Per Million Opportunities (DPMO), sigma level calculations, and fishbone diagrams. The results indicate that Black Cont (D1), Fil Drop (D7), and Cont Net (D3) are the dominant defects, contributing approximately 92% of total defects. The DPMO values ranged from 12,755,102 to 17,699,115, with sigma levels between 3.87 and 3.99, indicating that the production process performs reasonably well but still requires quality improvement. The novelty of this study lies in the integrated application of Six Sigma to prioritize quality improvement in spunbond fabric production. The findings provide practical recommendations, including improving operator competence, machine maintenance, SOP implementation, raw material quality control, inspection systems, and production environment management to reduce product defects.

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

Financial management is an important skill for students in meeting daily needs and achieving planned financial goals. However, many students still experience difficulties in managing their finances due to the lack of a habit of recording income and expenses regularly. This study aims to design a student financial recording application using the User Centered Design (UCD) method. The UCD method was chosen because it focuses on user needs, characteristics, and experiences throughout the system design process. Data were collected through interviews with five students to identify user problems, needs, and expectations. The research stages included user interviews, user persona development, Customer Journey Map creation, User FLow design, and wireframe development. The results showed that students need a simple and easy-to-use application equipped with features such as income and expense recording, balance information, financial reports, expense charts, savings targets, and transaction reminders. The design result is a wireframe consisting of login, dashboard, transaction, transaction history, and user profile pages. The implementation of the User Centered Design method produced an application design that aligns with user needs and is expected to help students manage their finances more effectively, systematically, and efficiently.

Abstract

This article critically examines the implementation of Design Thinking in the development of Zenius Education, an Indonesian EdTech platform, during 2020-2024. Using a qualitative explanatory single-case study design, the study analyzes the paradox between successful user empathy and ecosystem failure that led Zenius to cease operations in 2024. Findings show that Zenius succeeded on the desirability pillar (content quality acknowledged as superior) but failed systematically on the viability pillar, scoring 2/10 on an ecosystem index compared to its closest competitor Ruangguru at 8/10. Analysis through Brown's (2008) three-pillar framework, Matthews and Wrigley's (2017) design-maturity spectrum, and Sreenivasan and Suresh's (2024) Design Thinking-Lean Start-up integration theory reveals that Zenius remained trapped at the Human-Centered Design level without transforming toward Design as Strategy. The study proposes the concept of the “Design Thinking illusion”: a condition in which user empathy is achieved yet fails to sustain business viability due to an insufficiently framed wicked problem. Practical implications are directed at UI/UX designers to move beyond interface competence toward ecosystem design that builds switching costs and long-term user loyalty.
