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.

Procurement of machinery is a facilitation to overcome auction problems in accordance with the strategic plan of the Dinas TPHPKP to maintain and improve the quality or quality of commodities so as to increase the selling value. To carry out this facilitation with limited funds, other sources of subsidized funds are needed, the government needs tools to determine the nominal funding decision, the decision to place the machine, and the feasibility study of the model. Based on surveys, interviews, and previous research, the research data was processed using goal programming with Excel and ILOG CPLEX. This study chooses scenario three as the optimal scenario because the nominal subsidy of funds is smaller than scenarios one and two, but results in machine option decisions on each quality improvement function with a positive benefit deviation value of Rp. 20,014,000. This study succeeded in formulating a fund allocation model, determining five locations for placing machines and stating the feasibility of a fund allocation model with a Benefit Cost Ratio value of 1.49. Future research is expected to be able to consider the cost of energy consumption in the next use of the machine, consider the form of village assets as a candidate for placing the machine, and calculate other feasibility study parameters.

The concept of blood supply chain is distribute blood products safely, cheaply, and accessible to patients. There are four main activities in the blood supply chain, namely blood collection, blood processing, laboratory testing, and storage and distribution of blood products. The current development of PMI Gunungkidul Regency in carrying out its duties is still hampered by several things caused by risks, one of which is supply and demand uncertainty. In 2021, the blood supply at PMI will still experience a crisis of decreasing by 20%-30%, while the demand for blood from hospitals continues to exist and fluctuates. Based on the results of House of Risk Phase 1, there are 10 dominant risks that affect the blood supply chain. The results of the House of Risk Phase 2 resulted in preventative action to handle the 10 dominant risks. Apart from that, the results of the key risk indicators (KRI) are used as an early warning system for PMI Gunungkidul Regency. Implementation of preventive actions that have been designed and implemented key risk indicators, namely the number of blood bag supplies per month with a limit value of 79 blood bags and 399 blood bags.

Making stamped batik goes through 5 stages, namely tasting, dyeing color, removing hot and cold tubs, and drying. This process takes place repeatedly for a long time, causing workers to potentially experience musculoskeletal complaints and the risk of Cumulative Trauma Disorders (CTDs). The purpose of this study was to determine whether batik Nilo Tirto workers were at risk for developing CTDs or not. This research was conducted by using a method to determine the level of worker complaints with a Nordic Body Map (NBM) questionnaire. After knowing each class of worker complaints, the CTDs Risk Index method is used to determine the risk score for muscle injury in workers. If the score is > 1, it is relatively unsafe, so it needs improvement. The 2 most significant scores on the CTDs Risk Index worksheet will be analyzed further to determine the risk factors for musculoskeletal use using the PLIBEL Checklist. The results obtained are, there are 2 workstations that have the highest score on the CTDs Risk Index, namely color dyeing and cold bathing. This is caused by awkward body postures when working, repetitive movements, and poor workstation conditions, so the repair needs to be done. The results of this study can be used for improvements to the workstation for dyeing color and cold tubing in the form of design proposals and the work postures of the two workers.

The opportunities for developing grapes on an agribusiness and agroindustry scale in Indonesia are very high but have not been widely implemented. The aim of this research is to analyze the obstacles to the development of the current downstream grape supply chain. To develop the downstream grape supply chain, the first step is to identify the sub-elements that are part of the affected sector elements, the obstacles that occur and the programs needed. Identification of sub elements is carried out using ISM. Based on the results of the Interpretive Structural Modeling (ISM) analysis, the results showed that the obstacles to the downstreaming of the wine supply chain were that it had not paid attention to farmers who were the most important actors, had not designed a quality assurance system which was a program that should have been designed from the start of downstream planning and didn’t pay attention to the availability of materials. standard which is the main obstacle that has not been implemented so far. These three sub-elements can be integrated for institutional design to make downstream activities easier.

Based on data from SIPSN, the total national waste generation consisting of 200 regencies or cities has reached 21.45 million tons in 2021. Of the total national waste pile, 7.13 million tons (33.26%) are still unmanaged. To help resolve this issue, PT NS together with PT M organized waste bank program which aims to build and develop more waste banks, but fact on the field showed that not all waste bank movements can run smoothly. Therefore, an analysis of the performance of waste bank services was carried out using the balanced scorecard and long-term strategic planning was conducted using hoshin kanri. From the results of the 9 prioritized strategic goals weighting, it was found that increase in profit has the greatest weight with value of 0.171. While new customer acquisition has the smallest weight with value of 0.070. From the performance evaluation carried out with objective matrix and traffic light system, there are 4 performance indicators in green, 1 in yellow, and 4 in red. After this, strategic planning can be carried out using the hoshin kanri strategy map to provide long-term strategy that can help waste banks in the program to operate sustainably.
