Format The palm oil industry is a strategic sector that makes a significant contribution to the Indonesian economy, particularly in the plantation sector . , . , . However, the success of the palm oil industry also presents new challenges. One challenge is the large amount of palm leaf waste that remains underutilized . Much of this palm leaf waste is simply left to rot, leading to environmental pollution. A one-hectare palm oil plantation with approximately 130 trees produces a significant amount of biomass waste . Each tree produces approximately 22 fronds per year, with a total weight of 9 tons of fresh fronds . quivalent to 0. 66 tons of dry matte. per hectare. This palm oil waste, particularly the palm leaf frond waste, has significant potential for improving people's livelihoods if further processed . This initiative aligns with efforts to reduce waste and the environmental impact of the palm oil industry . One innovation is utilizing palm leaf midribs to create added value, such as palm fronds. Currently, the process of producing palm fronds is still carried out manually, which is time-consuming and inefficient for large-scale production . This is the formulation of the problem in this study. Furthermore, we need to know that Indonesia is one of the main producers with great potential to export palm fronds to countries with high market potential. The manual production of palm fronds remains prevalent in palm oil-growing communities. The process of making palm fronds manually is still widely practiced by communities in palm oil-producing areas. This traditional method is time-consuming, requires a lot of energy, and produces inconsistent results. Furthermore, the process of peeling and shredding palm frond veins manually often causes fatigue in workers and low productivity. These problems indicate the need for innovation in the form of a palm frond shredding machine that can improve work efficiency and production quality. Through the design of the right palm frond shredding machine, it is hoped that the process of processing palm fronds into palm fronds can be done more quickly, efficiently, and produce uniform sizes . In addition, the use of this machine can open new business opportunities for communities around palm oil plantations, increase the added value of agricultural waste, and support efforts to develop small and medium-sized industries based on local Thus, the design of a palm leaf shredding machine is not only a technical solution to increase productivity, but also plays an important role in supporting the circular economy and sustainable development in the agricultural sector . Based on previous research . , that the palm oil palm frond shredder machine using an electric motor with a capacity of 1800 fronds/hour is still not able to increase waste processing productivity by Another study developed a separator machine using a roll-pulling mechanism with a capacity of 7 kg/hour . 11 kg/minut. , which was also considered suboptimal . The novelty of this research lies in designing an improved palm frond separator machine that emphasizes enhanced maintainability, specifically through the ease of disassembling the leaf-chopping shaft for cleaning and replacing worn chopper components. This design aims to significantly increase productivity in palm leaf waste recycling, ultimately supporting circular economy principles and sustainable development in the agricultural sector . Based on the results of research 2 . , that the manufacture of a machine as a separator between palm oil fronds and leaves uses a roll as a puller with a capacity of 7 kg/hour, meaning that in one minute it can produce 0. 11 kg. Both studies stated that the results are still not effective and For this reason, the novelty of this research will design a palm oil frond separator machine with the advantages of the design offered providing ease of maintenance, namely the ease of removing the leaf chopper shaft part for cleaning and replacing the chopper component if the function has begun to The design o ffered can also increase productivity in the recycling process of palm leaf waste. The purpose of this research is to utilize palm leaf waste as the main material for making fronds by designing an efficient frond making machine that emphasizes the design of the machine on function, capacity and safety.
