Biogas is an alternative energy source that is environmentally friendly, cheap, easy to obtain and renewable. In general, all types of organic materials can be processed to produce biogas, however only homogeneous organic materials (solid and liquid) such as manure and urine (urine) of livestock are suitable for a simple biogas system. Biogas can be burned like LPG and on a large scale can be used to generate electricity, so that biogas can be used as an alternative energy source that is environmentally friendly and renewable. To determine the performance of biogas as an alternative energy source, in this research the method used is to compare the performance of Biogas with LPG gas as a source of electrical energy. Analysis of trial data per minute (RPM), with varying load levels, shows that the RPM of generators using LPG only decreases slightly as the electrical load increases, which shows that the generator is able to maintain more consistent performance. The RPM produced by LPG, which ranges from 2358 to 2420 RPM, indicates that the engine is running faster and more efficiently, while biogas has a lower RPM, ranging from 1715 to 1820 RPM, which indicates slower operation. LPG efficiency ranges from 89.60% to 98.12%, while biogas efficiency ranges from 74.67% to 89.60%. Even though biogas shows less stable performance than LPG, biogas still has potential as an alternative fuel, especially in areas that have limited access to LPG but have abundant sources of biogas raw materials. The use of biogas can reduce dependence on fossil fuels and reduce greenhouse gas emissions. Even though LPG is more efficient, biogas has significant potential to be developed as a more environmentally friendly alternative energy source because LPG relies on non-renewable fossil fuels and has a negative impact on the environment in the long term.

Agricultural tools are important for agrarian communities. However, for some people in Banyumas Regency, Central Java, very few people have businesses in the agricultural tools sector. In fact, this can be a promising business opportunity. Knowledge about making blacksmith agricultural tools is generally obtained from generation to generation. Some blacksmiths in Banyumas generally only produce agricultural tools such as kudi and work machetes, because the need for these tools never stops, is always needed by farmers or workers, and the equipment produced does not require high design, even tends to be monotonous because the main thing is its function as work equipment. That is why Science and Technology for the Community (IbM) was implemented at the Pandai Besi Kirso production house on November 6, 2025, as a method of increasing production. IbM was continued with training in techniques for selecting raw materials, making potions that can improve the quality of iron, and making a variety of new products with high quality both in terms of strength and aesthetics. It was identified that agricultural tool craftsmen generally (1) Have limitations in equipment, (2) Lack expertise in metal blending, (3) Lack of innovative product variations, not only quality but also unique ethnic ones and (4) Low management quality. The implementation of IbM is expected to be able to minimize the problems of agricultural tool craftsmen's businesses, so that the blacksmith craftsmen's community businesses can develop and have a positive impact on the existence of MSMEs in Banyumas Regency.
