This study was conducted at a pharmaceutical manufacturing company, focusing on the blistering process of capsule products. Quality control issues were identified, particularly defects that do not meet company standards. The objective of this research is to identify the root causes of defects and propose improvements using the Poka Yoke and Kaizen methods. The study is limited to defects found in capsules that have passed the blistering stage, including crushed capsules, dirt contamination, misprinted expiration dates, and empty capsules. The capsules used in the study already meet company standards before processing. The analysis applies the Six Sigma methodology with the DMAIC approach (Define, Measure, Analyze, Improve, Control). Results from January 2024 to March 2025 show a DPMO value of 9100.625 and a sigma level of 3.86. The Pareto diagram indicates that the most dominant defects are crushed capsules (35.8%) and dirty capsules (30%). Based on FMEA analysis, the highest RPN values are caused by capsule misalignment in the blister machine (for crushed defects) and powder residue sticking to the sealing area (for dirty defects). Improvements are proposed using Poka Yoke techniques and continuous improvement through Kaizen, specifically applying the 5M and 5S principles.

This research was conducted in a micro, small and medium enterprise (MSME) which produces apparel with its own brand. Even though they have been producing clothes since October 2020, sales have not met the target so the owner decided to temporarily stop the business with plans to continue after having sufficient capital. This study aims to determine consumer expectations for pajama products, measure the gap between expectations and products, and provide a design for the development of product quality using the Kansei Engineering and Quality Function Deployment (QFD). By processing the results of the first questionnaire and grouping the attributes into the eight dimensions of product quality, the eight most important attributes were comfort, pockets on shirt, safe, durable, smooth, easy to buy, affordable, and minimalist. The second questionnaire asked respondents to express their level of expectations and perceptions of the main product, competitor 1 and 2, which were then used to conduct a gap analysis. The gap value showed that consumer satisfaction with the main pajama product is lower than competitor 1, but higher than competitor 2, where the main product has an advantage in the 'affordable price' attribute. Furthermore, the three phases of the House of Quality (HOQ) provided manufacturing planning results in the form of using materials without defects, cotton and cotton t-shirt materials, plain or minimalist motifs, short sleeve and short pants model, variations in sizes M, L, and XL for all models, and the provision of pockets in shirts and pajama pants.

Environmental awareness is something that really needs to be introduced in various circles. This also needs to be instilled in the church through movements in each environment. The PKM team partners with one of the neighborhoods in this church, namely the St. Yulius neighborhood with around 60 heads of families. The St Yulius environmental sector feels it is necessary to develop educational activities and real practices, so that people become more aware of the problem of global warming. Currently, Yulius's environment has sorted its waste, made eco enzymes, and planted and cared for trees. Seeing the existing behavior, the PKM team proposed a training that could increase people's knowledge and real practice through making kombucha. In this PKM, participants are taught how to make kombucha tea and kombucha coffee as probiotic drinks, namely drinks that contain good microorganisms to maintain a healthy digestive tract. Apart from that, participants also learned about advanced processing of kombucha for home SPA products such as skin cream, skin toner and hair tonic. Based on the questionnaire distributed, all participants who took part in this activity said this activity was very useful and increased their insight. Through this training, it is also hoped that awareness will grow among participants regarding the problem of global warming which has a negative impact on colonies of microorganisms that are invisible to the eye. In fact, humans really need the presence of colonies of microorganisms that are good for the health of the human body ABSTRAK Kepedulian lingkungan hidup adalah hal yang sangat perlu dikenalkan di berbagai kalangan. Hal ini juga perlu ditanamkan di gereja melalui gerakkan di masing-masing lingkungan. Tim PKM bermitra dengan salah satu lingkungan yang ada di Gereja ini, yaitu lingkungan st Yulius dengan jumlah kepala keluarga sekitar 60 kepala. Sie lingkungan hidup St Yulius merasa perlu mengembangkan kegiatan edukasi dan praktik nyata, agar umat semakin peduli terhadap masalah pemanasan global. Saat ini lingkungan Yulius sudah memilah sampahnya, membuat eco enzim, serta menanam dan merawat pohon. Melihat perilaku yang ada maka, tim PKM mengusulkan suatu pelatihan yang dapat menambah pengetahuan dan praktik nyata umat melalui pembuatan kombucha. Dalam PKM ini, peserta diajarkan cara pembuatan teh kombucha dan kopi kombucha sebagai minuman probiotik, yaitu minuman yang mengandung mikroorganisme baik untuk menjaga kesehatan saluran pencernaan. Selain itu, peserta juga mempelajari pengolahan lanjutan kombucha untuk produk SPA rumahan seperti krem kulit, toner kulit dan tonik rambut. Seluruh peserta yang mengikuti kegiatan ini berdasarkan kuesioner yang disebarkan mengatakan kegiatan ini sangat bermanfaat dan menambah wawasan mereka. Melalui pelatihan ini juga diharapkan semakin tumbuh kesadaran di kalangan peserta akan masalah pemanasan global yang berdampak buruk bagi koloni mikroorganisme yang tak tampak oleh mata. Sementara disisi lain manusia juga sangat membutuhkan kehadiran koloni mikroorganisme yang baik untuk kesehatan tubuh manusia.

This safety shoe company is a manufacturing company that faces various quality issues, such as defects in stitching, leather, mismatched shoe pairs, and incomplete components. Based on production data from March 2024 to February 2025, the most dominant defects were “Mismatched Pairs” and “Incomplete Components,” with a total of 3,694 defective pairs out of 120,000 produced, resulting in a DPMO value of 7,695.83. This study aims to identify the root causes of these defects and design quality improvement solutions using the New Seven Quality Tools and PokaYoke methods. Data were collected through field observations and literature reviews, then analyzed using tools such as the Pareto Diagram, Affinity Diagram, Interrelationship Diagram, Tree Diagram, and Matrix Analysis. The results show that immediate corrective actions include the development of standard operating procedures (SOPs), routine socialization, daily briefings, improved lighting, and component replacement. Long- term solutions, such as adding conveyor belts and implementing preventive maintenance, could not yet be executed due to time and cost constraints. Implementation efforts focused on developing a Poka Yoke-based SOP at the packing station as a concrete step toward improving product quality.

Increasingly fierce industrial competition requires companies to continuously improve the quality of their products to meet customer expectations and maintain competitiveness. This research was conducted at PT XYZ, a manufacturing company that produces Bottled Drinking Water (AMDK), with a focus on cup packaging products. The purpose of this research is to identify the types and causes of product defects, and formulate a quality improvement strategy using the Six Sigma method based on the DMAIC (Define, Measure, Analyze, Improve, Control) and Quality Function Deployment (QFD) approaches. The observation results show that the dominant types of defects are frosted cups, mushy cups, striped cups, and cup sizes that exceed the standard. The Defect per Million Opportunities (DPMO) calculation shows a value of 5.755 with a sigma level of 4, which means that the production process still requires significant improvement to achieve the Six Sigma target. Through the QFD stage, customer requirements are translated into technical characteristics that form the basis for the development of the House of Quality (HoQ). The results of this study provide a quality improvement strategy that is more structured and oriented to customer needs, and can be used as a reference for continuous improvement in the mineral water industry.

Many sellers of goods through digital platforms (marketplaces) do not have large storage space, so currently logistics companies also provide warehouse services to store goods from these sellers. A good warehouse management system (WMS) must be able to flow goods from input to output effectively and efficiently. Many logistics companies have yet to comprehensively measure key performance indicators (KPIs) for their WMS due to the perception that measurement is difficult and should only be performed by experts. This study aims to design and measure the KPIs of a WMS. This study uses a case study approach in a logistics company that has a storage area for various types of goods from sellers. Data were collected through literature studies, observations, and interviews. The methods used were the Analytical Hierarchy Process (AHP) and Snorm De Boer. The results show that three KPIs fall into the poor category, including: putaway per man-hour, % location and cube occupied, and order lines picked per man-hour. The company needs to create a structured system for storing goods based on their type, set standard storage time limits or even increase storage capacity, and also need to monitor the smooth flow of goods. In the end, it is hoped that all proposed KPIs can be measured periodically for continuous improvement.
