Abstract

In the industrial world, the quality and productivity of products play a crucial role in the success of various production systems. The ceramic industry encounters challenges related to defective products due to various factors. When COVID-19 struck, one ceramic tile company temporarily laid off workers and suspended operations at several plants due to a decrease in orders. In January 2023, the company only opened three plants. It was found that many problems were encountered particularly with the production of SL-type ceramic tiles (25 cm × 25 cm). They were still striving to reduce these issues and ensure smooth production processes. The problems that frequently occur can be attributed to the production process, materials, machinery, or human factors. Consequently, research has been conducted to control defective products, thereby enhancing production quality using the Six Sigma DMAIC method. The DMAIC methodology is the cornerstone of Six Sigma problem-solving, involving sequential improvement steps. These steps in the DMAIC method include Define, Measure, Analyze, Improve, and Control. Based on the conducted calculations, an average DPMO (Defects per Million Opportunities) value of 8621.2 was obtained, with an average sigma value of 3.91. DPMO, which measures failure in the DMAIC method, indicates failures per million opportunities. Based on this, it suggests that production falls within the average category of the Indonesian industry and is deemed sufficiently satisfactory. This study also provides improvement steps that need to be taken to reduce defective products.

Abstract

Puskesmas XYZ, situated in Cilegon City, serves one or multiple sub-districts as a primary healthcare facility, boasting a commendable performance rating of 3.66. To elevate service quality, the Mayor of Cilegon has suggested transitioning to the Regional Public Service Agency system, granting the health center operational autonomy apart from local government dependencies. Despite its laudable performance, Puskesmas XYZ requires enhancements to adopt the BLUD system, as indicated in Cilegon's 2020 Public Service Assessment Report. The report highlights six areas necessitating improvement: service policies, professional human resources, information systems, facilities, and infrastructure, as well as consultation and complaint mechanisms. This study aims to assess and prioritize improvement strategies using the Servperf model and PROMETHEE method. PROMETHEE calculations identified 10 alternatives with negative net flow: E4, RS2, TA3, E3, E5, AS2, RS3, AS1, RS4, and E1. Moreover, the process definition mapping identified 5 alternatives with activity flows across administration, general polyclinic, and pharmacy sections. This breakdown includes 11 activities as VA, 7 as NVA, and 2 as NNVA. Additionally, a root cause analysis (RCA) employing the 5 Whys method was conducted to identify issues and propose viable enhancements for Puskesmas XYZ. These measures aim to empower the health center, fortify its services, rectify weaknesses, and ultimately bolster healthcare provisions for the community.

Abstract

The growth of small and medium-scale industries has significantly influenced regional economies. These industries, spanning from food production, handicrafts, furniture, to textiles and garment manufacturing, play a crucial role in addressing unemployment rates and bolstering regional economic development. To support small and medium enterprises (SMEs), the government has introduced the People's Business Credit Program (KUR). Besides the KUR program, SMEs receive capital aid and guidance from neighboring companies through what is commonly known as Corporate Social Responsibility (CSR). This study aims to explore the relationship between CSR assistance, KUR, and entrepreneurship in enhancing SME performance. Employing the Structural Equation Modeling (SEM) method, the research investigates causal links between independent and dependent variables, assessing the validity and reliability of the research instrument overall. SEM facilitates the examination of intricate variable relationships to provide an overarching view of the model. Upon data collection and analysis, this study concludes that there exists a causal relationship between CSR and KUR in relation to entrepreneurship, with a total effect value of 0.36. Furthermore, there is a correlation between CSR, KUR, and entrepreneurship, contributing to the enhancement of SME performance, with an indirect effect value of 0.25.

Abstract

Most Medium, Small, and Micro Enterprises (MSMEs) in the culinary sector are experiencing the fastest growth and increasing trends in demand and income, indicating the potential for business expansion. However, many MSMEs have encountered several problems in their supply chain that could jeopardize business continuity. The objectives of this research are: 1) to identify risk events and risk sources (risk agents) and prioritize them; and 2) to determine the mitigation actions (preventive actions) that MSMEs need to undertake to minimize risks. The identification of risk events is conducted using the SCOR (Supply Chain Operation Reference) approach, while data analysis employs the HOR (House of Risk) method. It is revealed that there are 38 risk events with 24 risk sources. From the three priority risk sources, 8 mitigation actions were developed, with 3 priority mitigation actions identified: determining supplier criteria, establishing minimum order time regulations, and maintaining records related to production raw material stocks.

Abstract

In contemporary times, the use of smartphones has become an essential requirement for daily life in the digital era. The prevalent consequences of smartphone usage include the development of poor posture and behaviors. This study aimed to assess the risk of musculoskeletal disorders (MSD) among smartphone users, focusing on adolescents aged 12 to 19 years. A sample of 82 students (79.3% female and 20.7% male, with an average age of 15.7 ± 2 years and a normal BMI of 76.8%) in the West Lombok district of the West Nusa Tenggara Province in Indonesia was measured. Data collection through simple random sampling involved distributing questionnaires to participants and requesting them to provide responses based on their personal experiences. The present study employs a chi-square analysis to examine the association between smartphone usage, posture behavior, and the highest values of MSD complaints. The findings indicate that the neck (46.3%) and back (45.1%) were the body regions with the most prevalent complaints of MSD. The participants frequently engaged in standing without support and walking as their posture behaviors. There was a significant correlation between the level of neck pain and posture during walking. The use of smartphones among adolescents has an impact on the risk level of experiencing MSD complaints, thereby increasing the potential for illness and abnormalities. Hence, it is necessary to exercise sufficient control over the routine usage of smartphones to mitigate the negative impacts incurred.

Abstract

Supply chain risk management plays a pivotal role for businesses, regardless of their size—be it large industries or Micro, Small, and Medium Enterprises (MSMEs). Even in MSMEs, supply chain risk management is crucial to mitigate potential risks stemming from various events. Consider BS, an MSME producing bread in Cilegon city, established in 2020, aspiring for market expansion. However, BS faces internal challenges such as fluctuating flour availability, recurring machine breakdowns twice a month, and consumer returns due to order discrepancies. Thus, this study aims to analyze supply chain risks to proactively prevent these recurrent events. The method employed here is the House of Risk. Through data processing, 32 risk events were identified by mapping supply chain activities based on the SCOR principle. From these events, 18 risk agents were derived, highlighting critical areas that require resolution. Employing a Pareto diagram, six priority risk agents have been identified for immediate resolution.

Abstract

Customer service quality is a key performance indicator that directly impacts a company's image. This study identified potential issues with a mobile banking app (m-banking) based on its low rating on the Google Play Store compared to similar apps. The app's rating likely reflects user satisfaction with the m-banking service. To address these concerns and improve service quality based on user feedback (voice of customer), a study was conducted using three methods: text mining, mobile banking service quality analysis, and Quality Function Deployment (QFD). The text mining method analyzed sentiment from comments on the Google Play Store. It employed a Support Vector Machine (SVM) algorithm, achieving high accuracy (0.86), precision (0.86), recall (0.84), F1-score (0.85), and AUC (0.84). Negative sentiment analysis identified five dimensions encompassing 15 attributes of m-banking service quality. These attributes were then incorporated into a questionnaire distributed to 100 respondents. Six attributes with the lowest gap values were identified as priority attributes, representing the most critical customer concerns. These attributes were used as the "voice of the customer" in the QFD method. By constructing a House of Quality (HoQ) matrix, the study established a priority ranking of technical responses. These responses include strategies to optimize tools, application features, and memory usage, reduce excessive animation and the use of live wallpapers, create an update mechanism, provide content localization features, continuously incorporate customer feedback into application improvements.
