Abstract

ABSTRACT One of the keys to success in winning industry competition in the future or in the era globalization is to pay attention to quality issue. For that reason, if a company wants to survive, particularly in facing the future, so are required to pay attention to the quality.PT Ho Wah Genting is company operating in manufacturing sector that produces cable wire, by which one product is TLS. According to observation, there were three problems during the printing procces. Malformed product is being, and less product defects. The research on p’s control maps show that there’s data that’s out of control. Based on the analysis of the defect using the fishbone diagram for every flaw there are some factor which are human being. Machines, method, material, and also the neigborhood. Based on the analysis in the field, the product defects cannot be eliminated because when the machine is set up, it will also defect product. Based on the three alternative design tools obtained, the third design alternative was chosen because it is effective in helping operators maintain product quality and in accordance white the constraints faced by operators during the production process.

Abstract

In the midst of the current manufacturing industry competition, companies are required to maintain the quality of their produced products. PT ABC is one of the manufacturing companies engaged in the production of electronic and medical products. In this study, issues were identified in the molding department, which had a high number of black dot defects in Housing Bottom products. The objective of this research is to determine the factors causing the decline in the quality of Housing Bottom products and to identify improvement efforts for the black dot defects. This study uses a fishbone diagram to analyze the factors causing black dot defects and the DMAIC method to determine improvement efforts for the causes of black dot defects. The research findings using the fishbone diagram identified that the cause of black dot defects is a machine factor related to nozzle temperature. Therefore, the improvement efforts conducted using Design of Experiment involve setting the nozzle temperature at 290°C and the metering section temperature at 290°C, resulting in low black dot defects.

Abstract

One of the accommodations that is needed to support tourism is the availability of hotelsor inns. This is what makes entrepreneurs, especially in the field of hospitality, compete todevelop their business to attract visitors. ABC Resort is one of the companies engaged inthe accommodation sector which is most attractive to domestic and foreign touristsbecause of its location on the seafront directly adjacent to the Singapore Strait. Thepurpose of this study is to identify and analyze the standard criteria of hotel services inBatam city based on the hotel classification. The data obtained from the Voice of Customer(VoC) questionnaire will then be used as a guide in building the House of Quality (HoQ).Based on the calculation of the House of Quality (HoQ), it is known that there are 5 criteriafor service characteristics that have the highest priority value, namely the Hotel has aRestaurant and Bar with a Relative Importance Rate (TKR) value of 11%, Gym facilities,spa massage and sports healing with a TKR value of 10.2%, Availability of clean toilet andbathroom facilities with a TKR value of 8.84%, Luxury hotel buildings with a TKR value of6.55% and Interior and exterior design with a TKR value of 5.66%.

Abstract

The poor quality of containers from trucking companies affected cocoa products and caused customer dissatisfaction and financial losses for PT XYZ, a cocoa product trading company. This research evaluates the quality of container procurement services from trucking companies using the SERVQUAL and Lean Service approach and DPMO and Six Sigma methods. This study also proposes a Self-Assessment Checksheet design based on SAC (Safety, Availability, and Cost) indicators from four standard sources of foodgrade containers. The design was validated and revised by two industry practitioners and one academic. The research results show that service quality has not met the expected standards, indicated by high DPMO values and low Six Sigma levels for all service dimensions, especially Responsiveness and Tangible. The Self-Assessment Checksheet design can help trucking companies improve the quality of their services and achieve better levels of Six Sigma by facilitating them to inspect and assess the quality of the containers they provide. This design is a solution for improvements in the Tangible dimension as the main focus of this research. This study concludes that the Self-Assessment Checksheet design is a useful tool for improving the quality of container procurement services and reducing problems and losses caused by poor quality containers.

Abstract

Competition in the food Industry, is not only on the scale of the output production or brand, but also on the quality of products produced. The company needs to take quality control measures to maintain the quality of their products to comfrom to the quality standards set by the company, so that their products can be accepted by consumers. Griya Kripik Tempe is a company in the food which in the production process the are still various and fluctuating defects.The purpose of this study was to identify the level of variation in defects in the production process, identify the level of quality control performance by finding the value of DPMO, and tools design of cutting with of QFD method, fishbone diagrams are used to identify the causes of defects. The results showed that there no data out of control limits by p-chart,this value is still relatively low. Based on the fishbone diagram, it was found that human, machine, method, material and environmental factors were the cause of defects in kripik tempe production. The result of designing a cube-shaped tempe cutting tool, with many blades, a lever for pressing and a container for pieces of tempe.

Abstract

JK Tofu SME still faces obstacles in meeting market demand due to wasteful activities in the production process, such as excessive soybean soaking time and inconsistent and unmeasured yeast addition. This study aims to identify factors affecting tofu production process quality and process requirement standards. The methods used are quantitative approaches through DPMO calculations, Value Stream Mapping, and QFD. The results show that the production process still has defects such as dirty, smelly, and soft tofu. Current Value Stream Mapping analysis indicates low efficiency with a PCE of 51.67% and non-value-added time (NVA and NNVA) of 290 minutes. After improvements through Future State Mapping, the PCE increased to 71.26% and the total process time decreased to 435 minutes. The average DPMO of 33,333.33 with a sigma level of 1.933 indicates that quality is still far from Six Sigma standards. Through QFD Levels 1–3, consumer needs are translated into technical specifications, product characteristics, and production process requirements. Specifications such as ingredient composition and cooking processes influence product quality, while integration across QFD levels strengthens quality control. QFD provides strategic and operational guidance for continuous product quality improvement. This study shows that analyzing the causes of waste can affect product quality and that it is necessary to determine process requirement standards.

Abstract

This study aims to analyze and propose improvements to the tofu production process at UKM Tahu Berkah Barokah based on Good Manufacturing Practice (GMP) and Workplace Improvement Strategies and Ergonomics (WISE) standards. Observations revealed several critical non-conformities, including an unclean and poorly maintained factory environment, inadequate sanitation facilities, and low employee awareness of personal hygiene. The average defect rate reached 14.98% per month, or 21,750 pieces out of 145,050 total production. The calculated DPMO value of 37,480 with a sigma level of 3.28 indicates inefficiencies in the process, while the Cpk value of 1.00 falls below the industry standard (≥1.33). Proposed improvements include enhancing workplace cleanliness, providing sanitation and OHS training, implementing production process supervision through documentation and regular audits, and encouraging active employee involvement in workplace innovation. The integration of GMP and WISE approaches is expected to reduce production defects, improve product quality, and create a healthier and more productive working environment on a sustainable basis.
