Abstract

Banjarwaru village is one of the villages in Cilacap district with the potential for wooden broom handle craft commodities. The processing of mahogany wood (Swietenia mahagoni) into broom handles produces wood waste that has not been utilized optimally. The accumulation of wood waste is caused by a lack of knowledge among the Banjarwaru village woodworking community regarding the potential dangers, benefits, and economic value of wood waste. Therefore, training in wood waste processing into value-added products such as particleboard is needed. The Community service team together with BUMDes Banjarwaru carried out mentoring activities as a solution method for utilizing wood waste. The mentoring activities carried out consist of educating the negative effects of wood waste on the environment, educating the potential and benefits of wood waste in another processed forms, and training in wood waste processing into particleboard. These series of activities succeeded in increasing the woodworking community understanding of wood waste by 81.6%. The success rate of mentoring reached 91,67% shown by 11 out of 12 mentoring participants understood the potential danger, benefits, and other processed forms of wood waste.

Abstract

Tingginya kebutuhan manusia akan sistem pendingin berakibat pada melonjaknya penggunaan refrigeran jenis hidrokarbon maupun fluorokarbon dari tahun ke tahun. Hidrokarbon dan fluorokarbon merupakan zat yang berbahaya karena dapat merusak lapisan ozon di stratosfer yang menyebabkan peningkatan sinar ultraviolet yang diterima oleh manusia di bumi sehingga berdampak buruk pada kesehatan. Sistem pendingin berbasis termoelektrik sebagai pompa kalor padat adalah salah satu solusi yang aman sebagai pengganti sistem pendingin hidrokarbon maupun fluorokarbon. Pada penelitian ini akan dilakukan eksperimen dari sebuah sistem pendingin berbasis termoelektrik dengan alat penukar kalor yang menggunakan air sebagai fluida kerjanya. Penelitian akan difokuskan pada unjuk kerja sistem yang optimal terhadap tegangan dan debit aliran air sebagai fluida kerja. Dari hasil pengujian diperoleh sistem optimal pada konsumsi tegangan 6V dan arus 2.24A, pada debit laju aliran air 0.5 liter/menit. Adapun COP dari sistem pada saat itu adalah sebesar 0.86.

Abstract

Background. BUMDes Banjarwaru Sejahtera is a business owned and managed by the people of Banjarwaru Village, Cilacap Regency. Some of the businesses that have been managed by BUMDes Banjarwaru Sejahtera include renting molen machines and making handicrafts such as broom handles and woven bamboo household crafts which produce an abundance of wood waste left over from the production process. So far, this wood waste has been sold to tofu craftsmen as fuel for the tofu production process. Purpose. People can use wood waste as added value by processing wood waste into handicrafts that have high economic value so that they can improve the welfare of the people of Banjarwaru village. Through this community service activity, training will be held on the use of wood waste chopping machines so that processed wood waste can be made into handicrafts such as particle boards or other handicrafts. Method. The method used is a lecture method where the community service team who are lecturers at the Cilacap State Polytechnic provide training on the use of wood waste chopping machines to members of BUMDes Banjarwaru Sejahtera and several wood craftsmen in Banjarwaru village. Results. The results of this community service activity have had a positive impact on business development at BUMDes Banjarwaru Sejahtera. Conclusion. Through this community service activity, it can be concluded that this activity has had a positive impact on the business development of BUMDes Banjarwaru Sejahtera. Apart from this, training in the use of wood waste chopping machines can also increase the competence of wood craftsmen in Banjarwaru village so they can produce more varied crafts made from wood waste.

Abstract

The trend of using electric motorbikes to drive two-wheeled vehicles in Indonesia has started to increase. This is because the increasing public awareness of the benefits of electric vehicles is linked to the decreasing fossil energy reserves. Apart from that, electric vehicles are an environmentally friendly means of transportation because they do not cause air pollution. Based on previously research SEMOLI Generation 1, it is known that the use of a sprocket and chain transmission model on electric motorbikes produces less than optimal performance when used on flat roads, because on flat roads there is no need for large torque. The aim of this SEMOLI Generation 2 research is to conduct experiments using a CVT transmission which is predicted to be able to provide large torque when the road conditions are uphill, and able to provide higher speeds when the road conditions are flat. The research stages carried out successively are: conducting studies, selecting transmissions, assembling, fabricating, designing frames and swing arms, testing, and preparing documents. Based on the test results, it was found that using a CVT was able to increase maximum speed on both horizontal and uphill road conditions. This increase is because CVT has a wide transmission comparison range, so it is able to overcome uphill and horizontal road conditions.
