Analysis of the Factors Influencing Parents' Satisfaction with the Free School Lunch Program
type: item
description: 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.

Optimizing Equipment Layout with ARC and 5S in a Metal Casting Molding Division
type: item
description: A metal casting manufacturing company operating in Ceper, Klaten. One of the key areas in its production process is the molding division, where casting molds are made. Several issues were identified in this area, including poor organization, inadequate cleanliness, and insufficient attention to workplace safety. This study aims to evaluate the implementation of the 5S culture (Seiri, Seiton, Seiso, Seiketsu, and Shitsuke) in the molding division and to propose improvements to enhance four key principles: effectiveness, efficiency, productivity, and occupational safety. Based on the results of the 5S questionnaire data analysis, the overall implementation level was relatively low at 52.78%, with Seiso scoring the highest (66%), followed by Shitsuke (57%), Seiri (54%), Seiton (51%), and Seiketsu (35%). To address these issues, several improvements were proposed, including procedures for item sorting, equipment labeling, implementation of workplace signage, development of Standard Operating Procedures (SOP) for machines, scheduling of machine/tool maintenance, and the establishment of a reward and punishment system. These efforts were further supported by optimizing the workplace layout using the Activity Relationship Chart (ARC) method. The implementation of these improvements resulted in a significant increase in the utilization of the production area, from 33% to 66%.

Determination of Preventive Maintenance Interval Based on Reliability Threshold and Risk-Based Maintenance
type: item
description: 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.

Risk Identification and Safety Assessment in Kemuning Sky Hills Tourism Area
type: item
description: 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.

Supply Chain Mapping of Pempek Products Through a Green Economy Approach
type: item
description: Indonesia is one of the most multicultural countries in the world, where each region has its own distinct characteristics and uniqueness, ranging from local languages, traditional clothing, dances, music, traditional ceremonies, handicrafts, and traditional foods. One of these diverse regions is South Sumatra, particularly the city of Palembang, which is famous for its iconic traditional food, pempek. Pempek not only represents the culture of Palembang but also serves as a vital contributor to the local economy. As demand for pempek continues to rise, both locally and from other regions, its production has grown significantly, leading to the rapid development of small and medium-sized enterprises (SMEs) to meet market needs. However, the production process of pempek, from suppliers to consumers, can have negative environmental impacts, such as the use of unsustainable raw materials, high energy consumption, and suboptimal waste management. Therefore, it is necessary to conduct research on sustainable production and distribution of pempek to minimize environmental damage. In this context, the application of a green economy approach is highly relevant. The green economy emphasizes resource efficiency, waste reduction, and environmental quality improvement. Without implementing green economy principles, the pempek industry has the potential to cause environmental degradation, threatening the natural resources that are essential for pempek production. The purpose of this study is to map the current supply chain of pempek products from upstream to downstream and to identify internal and external factors in implementing a green economy approach within the pempek product supply chain.

Packaging Design of Roti Ganda Pematangsiantar Using Kansei Engineering Method and The Kano Model
type: item
description: 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.

Cost of Quality Models in Continuous Production Systems with Deteriorating Quality: A Review and Research Agenda
type: item
description: 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

Implementation of Class-Based Storage for Warehouse Layout Optimization in Temperature-Controlled Raw Material Storage (Case Study: PT. XYZ)
type: item
description: 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 incor…

The Effect Of Green Supply Chain Management And Supply Chain Management Performance On Sustainable Performance
type: item
description: 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.

type: item
description: 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.

Cleaner Production in the Marble Industry (Case Study: UD Warna Utama)
type: item
description: UD Warna Utama is one of the marble stone industries located in Tulungagung, East Java. In the marble stone process, there are three stages of production, namely the sawing of marble blocks, the sawing of marble slabs, and the polishing of marble. In the production process, the waste generated is sometimes sold as building foundation material, while other residues are directly disposed of into the surrounding environment of the factory, causing environmental pollution. This research aims to identify opportunities for improving efficiency and reducing environmental impact, as well as providing alternative proposals to minimize and utilize the waste generated in accordance with the concept of clean production. A quick analysis of the material flow using the Quick Scan method and interviews yielded several options for implementing clean production, namely the Recycle and Reuse methods. The proposed alternatives were evaluated using the B/C Ratio and Payback Period feasibility analysis, resulting in viable proposals for implementation, including the creation of water retention systems for block stone sawing processes, selling sludge waste as construction material, making mosaics, and producing terrazzo.

Implementation of Taguchi Method in Optimizing Virgin Coconut Oil Extraction by Cooling and Centrifugation Techniques
type: item
description: Virgin Coconut Oil (VCO) extraction through refrigeration and centrifugation techniques has become the preferred extraction technique due to its ability to maintain oil quality. However, optimization of extraction yield and quality remains a challenge. Therefore, this study aims to identify the optimal factors in VCO extraction, focusing on yield and physicochemical quality, through the application of the Taguchi method. The factors tested included centrifugation speed, centrifugation time, storage temperature, and storage duration, each with three levels, using an orthogonal array L9(3^4). In addition, analysis of variance (ANOVA) was used to investigate the effects and contributions of each aspect. The experimental results indicated that centrifugation speed and storage temperature had significant effects on VCO yield, while centrifugation time and storage duration had minimal effects. Analysis of Variance (ANOVA) confirmed that centrifugation speed contributed 88.31% and storage temperature 7.68% to the yield. For the quality parameters of VCO content, such as moisture content, free fatty acids, total acid number, and peroxide value, no factor significantly affected the quality of VCO, indicating that this method is effective in maintaining quality under various conditions. These findings suggest that optimization of centrifugation speed and storage temperature can increase VCO yield without compromising quality. This research contributes to providing practical insights for efficient and high-quality VCO production, in accordance with the Indonesian National Standard (SNI 7381:2022) for VCO quality. Furthermore, VCO producers, including micro and small scale businesses, can produce large scale and consistent VCO without having to reduce product quality by optimizing centrifugation speed and storage temperature during the VCO manufacturing process.

Optimising Inventory Control in Pharmaceutical Distribution: A Case Study on PT. XYZ
type: item
description: Inventory control is a policy designed to manage and regulate the supply, storage, and accessibility of items in an organisation. Its primary purpose is to ensure that there is always enough stock on hand to meet demand while minimising the costs associated with holding and maintaining inventory. XYZ, a pharmaceutical distributor, faces challenges in optimising its inventory control policy, resulting in frequent stockouts, overstocks, and product damage during distribution. This study aims to design an optimised inventory control policy to enhance the Company's drug inventory system performance. The research begins by classifying inventory items using the ABC method and calculating the inventory turnover ratio (TOR). A scatter diagram is then constructed based on historical demand data to identify product demand patterns. Subsequently, three forecasting methods are applied, and the most accurate method is selected based on the Mean Absolute Percentage Error (MAPE). Inventory issues are categorised, with Class A drugs managed using the Q model and Classes B and C using the P model. The Hadley-Within method with backorder is employed for inventory problem-solving. The proposed inventory policy results in a total inventory cost of IDR 339,221,858 and a TOR of 4.26. In contrast, the existing system incurs a total inventory cost of IDR 1,338,286,901 with a TOR of 8.7. Implementing the optimised policy would lead to a cost reduction of 74.65%, equating to IDR 999,065,044, and improved inventory efficiency. This study provides a practical approach for pharmaceutical distributors to enhance inventory management, reduce costs, and optimise supply chain performance.
