XYZ company produce the various shape of motor spare parts product. The company has three identical parallel spot welding machines that use a random method of production scheduling, based on machine capacity without any sequence of jobs, and only use daily production targets given to operators. Based on the data, the actual scheduling of the machines has a very large completion time difference between each machine, or the machine loading is uneven. As a result, the makespan becomes longer with a value of 440000 seconds (26 days). This research aims to minimize the existing makespan by giving proposed scheduling, using the suggested algorithm method, which has a small number of iterations and has an optimal result. The method begins with the longest processing time sequence rule which is used as the upper bound for the first iteration, then continued to calculate the lower bound and machine workload. The calculation stops at the 15th iteration because the completion time value exceeds the lower and upper bound so that the optimal scheduling taken is scheduled in the 14th iteration with a makespan value of 914412 seconds (16 days). The proposed scheduling can minimize the makespan from the actual schedule by 38%.

Sukapura Village, located in Bandung Regency, has a Family Welfare Empowerment (PKK) program that includes various activities, such as the production of cassava chips. Currently, there is a high demand for cassava chips that cannot be met. Through analysis conducted by the community service team, it has been determined that the demand for cassava chips exceeds the production capacity. One of the contributing factors is the manual process involved in making cassava chips, which takes a relatively long time. One specific manual process is the mixing of cassava chips with dry seasoning. The cassava chips are placed in a container, and then dry spices are added. The mixing process is carried out by hand, ensuring that the spices are evenly distributed throughout the cassava chips. This manual process typically takes around 10-14 minutes for every 1.5 kg of cassava chips. To address this issue and improve efficiency, the community service team has designed and constructed a machine specifically for mixing dry seasoning. With this machine, the mixing process is significantly more efficient, taking less than 5 minutes to achieve optimal results. As a result, the time efficiency and productivity of the mixing process have greatly increased.
