Abstract

Control is a form of protection against various undesirable actions or disturbances, both internal and external, that can affect a system. This research aims to analyze defects in plywood products at the JatiMulyo Furniture Store using the Total Quality Control (TQC) method to determine priority problems that must be resolved first. The study adopts a mixed-method approach by combining qualitative and quantitative analyses. A fishbone diagram is utilized to systematically identify possible causes of defects. The findings reveal three main types of defects: cracked plywood (103 units, 32%), unsymmetrical plywood (114 units, 36%), and inappropriate plywood thickness (103 units, 32%), with a total of 320 defective units. No data correction was necessary as all percentages fall within acceptable limits. This thorough analysis enables the identification of key factors affecting product quality and provides direction for continuous improvement. The results are expected to guide quality control efforts. Further improvements can be made using continuous monitoring and corrective action.

Abstract

PT XYZ is a company that is competent in the manufacturing of aircraft and helicopters. In the aircraft production process, an aircraft painting process is carried out in the Painting Shop hangar. Painting on aircraft serves a dual purpose: protecting the aircraft from rust and corrosion, and representing the identity of a company or country. However, many defects are still found during this process that do not meet quality standards. This can be seen from the aircraft painting final inspection defect data for 2020-2023, 307 defects were found from 5 painted aircraft. This research employs the Failure Mode and Effect Analysis (FMEA) to identify failure modes in defects, their causes, and the severity, occurrence, detection, and Risk Priority Number (RPN) values of these defects, thereby determining repair priorities. The types of defects, misses, and runs fall into the high-risk category because they have an RPN value of >200, so they will be prioritized for immediate improvement. Fault Tree Analysis (FTA) is also used to identify the root causes of defects that occur. The causes of defects are attributed to human, machine, method, and environmental factors.

Abstract

This research analyzes the influence of Green Supply Chain Management (Green SCM) and Performance Supply Chain Management (Performance SCM) variables on environmental, economic and social dimensions, as well as their impact on sustainable performance. The confirmatory test results show that the construct indicators used are significant for measuring both endogenous and exogenous latent variables. The estimation method applied is maximum likelihood (ML), which searches for optimal parameters to produce the highest covariance. The proposed model meets most of the goodness of fit criteria, although it is not fit according to the chi square criteria, but is considered feasible based on the existing consensus. Hypothesis testing shows that Green SCM has a positive effect on the environment, economy and social. On the other hand, SCM Performance has no significant effect on the economy. Further analysis indicates that 43.5% of the economic variables can be explained by Green SCM and Performance SCM, while the remaining 56.5% is influenced by other factors. These findings emphasize the importance of implementing Green SCM in supporting sustainable performance.

Abstract

Indonesian society has long consumed tofu as a side dish or snack. A crucial issue identified in the packaging of Tahu Crispy is the use of non-food-grade duplex paper, which absorbs excessive oil, lacks product identity, and has an unattractive design. Therefore, this study aims to determine a suitable packaging design concept for Tahu Crispy. The Kansei Engineering method is employed due to its ability to interpret consumer impressions, emotions, and desires. The Kansei words were grouped using Principal Component Analysis (PCA). A total of 31 Kansei words were obtained through a questionnaire distributed with video stimuli. The data was then processed using R software, generating a design concept based on PCA input.

Abstract

Inefficiencies in temperature-controlled raw material warehouses, especially in the Fast-Moving Consumer Goods (FMCG) industry, can hinder production continuity and escalate operational costs. PT. XYZ, a leading cosmetic manufacturer, currently uses a Dedicated Storage system that fails to consider material movement frequency, resulting in limited storage slots, high material handling costs, and ineffective retrieval processes. To overcome these challenges, this study applied the Class-Based Storage (CBS) method by classifying materials into A (fast-moving), B (medium-moving), and C (slow-moving) categories based on their movement frequency. The contribution of this research lies in integrating CBS with the nearest location principle and simulation modeling to provide a structured solution for warehouse layout optimization. A quantitative approach was used by collecting outbound raw material data from January to December 2024, analyzing material movement frequency, and calculating material handling costs. The redesign of the warehouse layout considered the frequency-based classification and used AnyLogic software to simulate the proposed configuration. The analysis also involved calculating rectilinear distances and estimating handling costs based on operator and equipment expenses. The results showed that the proposed CBS-based layout reduced the total travel distance by 27.55% and decreased daily material handling costs by 28.67%. Additionally, high-frequency materials were positioned closer to the input/output points, improving accessibility and retrieval speed. The simulation confirmed increased warehouse efficiency, better space utilization, and reduced operator workload. In conclusion, the implementation of the CBS method in warehouse layout design significantly improved operational performance and reduced logistics costs. This study serves as a reference for companies managing temperature-sensitive inventory and provides a foundation for future research incorporating real-time inventory tracking and dynamic slotting systems.

Abstract

Cost of Quality (CoQ) is a critical tool in quality management, widely used to identify, evaluate, and optimize quality-related costs. While CoQ models such as the Prevention-Appraisal-Failure (PAF), Activity-Based Costing (ABC), Crosby, Opportunity Cost, and Process Costing have been extensively applied in discrete manufacturing systems, they remain underdeveloped for continuous production systems that exhibit time-dependent quality deterioration. This literature review explores the applicability of existing CoQ models to continuous and deteriorating systems. The analysis reveals that most CoQ models assume static failure behavior and do not accommodate gradual degradation or dynamic input quality. Among the models reviewed, the Opportunity Cost model is found to be the most conceptually aligned with dynamic loss due to declining quality, while ABC can complement it by tracing cost drivers linked to quality-related activities. Furthermore, this study outlines the potential of combining these models into a time-dependent dynamic CoQ framework, integrating deterioration functions and quality thresholds. Such a model could better represent the trade-off between prevention investments and the economic losses due to quality decay. Methodologically, this study employs a systematic literature review and comparative analysis to evaluate and synthesize prior CoQ models. The significance of this research lies in addressing theoretical and practical gaps in CoQ modeling for continuous production, which is increasingly important for industries striving for efficiency, competitiveness, and sustainability. This review ultimately provides a conceptual foundation for developing a mathematically optimized CoQ model for continuous systems, with potential validation through biogas production case studies

Abstract

This study aims to analyze parents' responses to the trial implementation of the Free Nutritious Meal Program (MBG) conducted in several elementary schools in Trenggalek Regency. The MBG program, initiated by the government, is in its pilot stage and primarily targets improvements in students' nutritional intake, health, academic performance, and efforts to reduce stunting. mploying a mixed-methods approach, the research combined qualitative insights from in-depth interviews with parents, teachers, and school principals, alongside quantitative data gathered from structured questionnaires distributed to parents involved in the pilot program. The study evaluated variables such as food quality, hygiene, serving frequency, school–parent communication, and parental expectations and concerns regarding the program’s continuity. The findings reveal a largely positive response; parents particularly appreciated the program's role in fostering healthier eating habits and alleviating household financial burdens. However, several critical issues emerged, including limited menu variety, inconsistent food taste quality, and lack of transparency regarding meal schedules and nutritional content. Some parents expressed hope for the program’s expansion, provided that food quality and safety standards are maintained. Further analysis indicates that effective communication and parental involvement significantly influence satisfaction and support levels for the program. These insights offer valuable input for local governments and schools in refining MBG implementation to maximize its impact. This research contributes to a better understanding of the dynamics of the MBG pilot at the elementary school level and provides data-driven recommendations to enhance future policy and execution of free nutritious meal programs.

Abstract

Ganda Bakery is a legendary food business that has been operating since 1979, located at Jl. Kartini No. 21, Pematangsiantar, North Sumatra. The main issue lies in one of its flagship products, the jumbo bread filled with srikaya, which still uses basic packaging made of paper and rubber bands, without any brand identity or appealing design. This has led to consumer complaints, especially from tourists, as the packaging is considered unattractive, non-functional, and impractical for use as a long-distance food souvenir. This study aims to design new packaging that reflects consumer preferences using the Kansei Engineering approach and the Kano Model. An initial questionnaire was distributed to 96 respondents, with 77.1% stating that the current packaging is neither attractive nor functional. The analysis generated 190 Kansei words, which were refined into 15 core descriptors, including durable, eye-catching, innovative, strong identity, and informative. These were then analyzed through validity, reliability, and factor analysis. The Kano Model results indicated that attributes such as informative, high-quality materials, shape that matches the contents, clear text, visual appeal, durability, ease of use, and illustration belong to the One-Dimensional category. Meanwhile, attributes like innovative, strong identity, and colourful packaging fall under the Attractive category, while varied typography and unique design are categorized as Indifferent. The best design, scoring 4.31, features a gable box measuring 26 × 10 × 16 cm, which is ergonomic and practical, made from thick art carton with a protective layer, in bright yellow and dark brown, and includes complete, easy-to-read product information.

Abstract

PT. XYZ is a company engaged in sugar production, where the cane cutter machine plays a critical role in shredding sugarcane before extraction. During the milling period from May to November 2023, the machine experienced 31 breakdowns, leading to considerable downtime and increased operational costs. This study determines maintenance intervals using the Risk-Based Maintenance (RBM) approach to assess risk levels and the Cost of Unreliability (COUR) method to quantify financial impacts. The initial RBM analysis identified a monthly risk value of IDR 47,147,150. By implementing scheduled replacement intervals—17 days for the cutting knife, 28 days for the cutting disk, 14 days for the bearing, 31 days for the conveyor, and 26 days for the driving turbine—the Cost of Reliability (COR) was established at IDR 76,700,415/month. Although the planned expenditure increased, it remains within the company's 2% tolerance limit at a 1.66% severity level. Furthermore, the COUR analysis revealed that the potential downtime loss of IDR 238,583,981 far outweighs the preventive investment. These results demonstrate that integrating RBM and COUR methods effectively balances maintenance costs while protecting the company from disproportionate financial losses due to equipment unreliability.

Abstract

Kemuning Sky Hills is a natural tourist attraction in Karanganyar Regency that offers various extreme rides, including a glass bridge, a sky swing, a flying chair, and a flying bicycle. Although it attracts tourists, the safety risks associated with these rides have not been optimally managed. This study aims to assess safety risks using the Hazard Identification, Risk Assessment, and Determination of Control (HIRADC) and provide a deeper understanding of the importance of safety risk analysis in extreme tourism destinations. The risk assessment is based on the Australian Standard HB 205-2004 reference. Data were collected through direct observation, interviews with officers and visitors, and field documentation. The results showed that several potential hazards fall into the High Risk to Extreme Risk categories. There are 10 risks in the High Risk category and 4 risks in the Extreme Risk category. The most extreme risks identified include overloading due to visitor density, gaps in the fence on the Glass Bridge, broken ropes on the Sky Swing, and the threat of landslides in the tourist area. Proposed controls include installing safety nets, rope guides, and warning signs, establishing a structured maintenance schedule, and providing education. This study concludes that safety management at Kemuning Sky Hills should be strengthened by implementing an integrated, structured safety management system that includes standardized operational procedures, routine risk assessments, clear emergency response mechanisms, and continuous staff training to ensure a consistently safe and sustainable tourist environment.
