The scarcity and possible depletion of energy sources in the future is due to the high energy consumption in the manufacturing industry. One of the efforts to deal with this problem is scheduling. This article investigates the Hybrid Flow Shop Scheduling Problem (HFSSP) to minimize energy consumption. A metaheuristic algorithm procedure is proposed, inspired by the Salp swarm in the ocean, the Salp Swarm Algorithm. The SSA algorithm is proposed to determine the optimal sequencing considering minimal energy consumption. An interesting finding of this study is that the higher the population and iterations, the lower the energy consumption. In addition, the optimization results show that the total energy consumption is due to variations in setup and removal energy consumption and idle machine energy consumption. From the numerical results, the SSA algorithm can produce scheduling with minimal energy consumption compared to the heuristic procedure.

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.

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 continuous use of fossil energy can have an impact on the energy crisis and environmental pollution Greenhouse Gas (GHG) is a contributing factor to climate change. Electric cars are one of the solutions to these problems. Because electric cars use clean and renewable electrical resources to drive their vehicles, they can reduce dependence on limited fossil fuels. In the use of electric cars that utilize regenerative braking technology, the first stage is to design the portion of mechanical braking on both the front and rear wheels, along with regenerative braking. The goal is to obtain a safe braking portion by following the ideal braking upper limit that has been set, as well as the lower limit set by the ECE braking standard. After obtaining a safe braking portion that is in accordance with actual conditions, the next step is to find the energy generated by the regenerative braking system by simulating it using Matlab-simulink. In this simulation, the regenerative brake efficiency can be obtained by comparing the absorbed energy and the available braking energy. The regenerative brake system in this study is able to absorb 1.7623 kWh of energy with an efficiency of 67.31% at a regenerative braking portion of 0.137 and front mechanical braking of 0.6629 at a road friction coefficient of 0.8.

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 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.
