Abstract

The problem of non-organic waste that is difficult to decompose has become a significant environmental issue in various regions, both urban and rural. To answer this challenge, the student team of the Student Work Lecture (KKM) 41 Year 2025 together with lecturers from the Industrial Engineering Study Program carried out community service activities in Mekarsari Village by designing and building waste incinerators based on appropriate technology, namely environmentally friendly and low-smoke rocket stoves. This activity was carried out through several stages, including initial surveys, location mapping, tool development, and evaluation of effectiveness by the local community. The rocket stove developed is designed to withstand combustion temperatures of up to 4000°C, with chimney temperatures ranging from 2000°C to 2500°C, and a maximum burning time of only 20 minutes. This efficiency shows that the combustion process takes place optimally. The sealed design with tight insulation using cement and hebel materials makes this tool safe, efficient, and environmentally friendly. This technology not only significantly reduces the volume of non-organic waste, but also reduces the impact of air pollution due to combustion fumes. Through a participatory and educational approach, the people of Mekarsari Village are actively involved in the process of building and utilizing tools, so that collective understanding and awareness of the importance of sustainable waste management is created. The results of this activity are expected to be an applicative solution in non-organic waste control at the local level, and can be replicated in other regions with similar characteristics. Thus, this service activity contributes to environmental preservation and improving the quality of life of the community through appropriate technological innovations.

Abstract

The lean approach is often used by manufacturing companies to increase productivity in the production area. In this case PT P, a manufacturing company that produces refrigerators, faces the same problem on the unloading process in the final assembly area. The unloading process is the operation to move the finished product from the production line and store it in the finished goods warehouse. Operators in the unloading area have tasks to unload finished products from conveyors which are connected directly from the assembly line and placing them on pallets. Due to the refrigerator is quite heavy a forklift has to use to move the full pallet to the finished goods warehouse which is located next to the unloading area. Once finished the forklift returns to the unloading area with the empty pallets and places them in the unloading area, to be refilled by the unloading operator. Based on the data taken, the cycle time in the unloading process was recorded to be varied and the highest was 33 seconds, exceeding the takt time that had been determined on the production line, which was 24 seconds. This means that there is waste that occurs in the unloading area. The long and unstable cycle time in the unloading process makes the production line disrupted because the conveyor often stops and causes productivity to drop. For this reason, it is necessary to analyze and improve the process with the Lean concept by reducing the existing waste, so that the cycle time becomes stable and smaller than the takt time.

Abstract

LP is one of the pharmaceutical companies located in Serang, Banten. The production of the company is tablets, capsules, and syrup. Problems that occur at PT. LP is a product defect that occurs in capsule filling, especially in capsule A. The purpose of this study is to determine the defective products that occur in capsule A and to find out the proposed improvements that will be made to reduce product defects in capsule A. The research methods used are Statistical Process Control (SPC) and Fuzzy Failure Mode and Effect Analysis (F-FMEA). The population and samples used were defective capsule A during the production process from March 2022 to May 2023, with sampling techniques through production data, observation and interviews. And the results of research using a check sheet show that the percentage of defects reaches 6%, based on the pareto chart, the priority of improvement that needs to be done is for the dominant type of defect, namely the dented capsule reject reaches 90%, and on the control chart there are still control points that are outside the UCL and LCL. FMEA calculations, the RPN value of the capsule is dented on the head of the capsule or capsule body reaches 384, and the FRPN value is 6.76.
