Abstract

Kaki palsu harus dirancang sedemikian rupa sehingga nyaman dipakai sepanjang hari. Ini mencakup pemilihan bahan yang lembut dan tahan lama untuk bagian yang bersentuhan dengan kulit, serta perpaduan yang baik antara dukungan struktural dan fleksibilitas. Pasien dengan amputasi kaki memiliki tantangan mobilitas dalam kehidupan sehari hari. Salah satu alat bantu gerak yang mampu secara efisien dan mandiri digunakan oleh pasien adalah kaki palsu. Terdapat beberapa jenis cacat dan kebutuhan kaki palsu, diantaranya adalah cacat pada bagian kaki bagian bawah / telapak kaki. Kaki palsu yang berada di pasaran Indonesia baru berpusat pada kaki palsu jenis konvensional yang tidak memberikan sensasi berjalan selayaknya orang normal. Maka dari itu perlu dikembangkan kaki palsu jenis ESR yang memberikan sensasi berjalan seperti orang normal karena kaki palsu jenis ini mampu menyimpan dan mengembalikan energi melalui mekanisme pegas. Tahapan penelitian yang akan dilakukan diantaranya adalah studi literatur dan referensi desain untuk reverse engineering, proses desain 3D dengan menerapkan kaida ergonomik, analisis biomekanik menggunakan metode finite elemen analysis, rapid prototyping 3 Printing, setelah itu dilakukan uji kekuatan mekanis dari hasil cetak 3D. Dari hasil penelitian menunjukkan bahwa desain kaki palsu yang telah dikembangkan, mampu menahan beban tubuh manusia.

Abstract

The design of a cassava slicing machine using the Pahl & Beitz method serves as a solution to improve production capacity and work efficiency in a cassava chips MSME located in Wonosobo, Central Java. The manual cassava slicing process often requires a long time, increases the risk of injury, and produces non-uniform slices. The Pahl & Beitz method is applied through four main stages: task clarification, concept development, form design, and design evaluation. This study presents novelty in implementing a V-belt and pulley-based transmission system with a compact dimensional configuration adapted to the limited production space of MSMEs, as well as the use of type 304 stainless steel to ensure product hygiene and machine durability. Compared to conventional slicing machines, this design demonstrates an increase in capacity of up to 70 kg/hour, along with better energy efficiency and operator safety. This research is expected to serve as a reference for the development of appropriate technology to support MSMEs in the food processing sector, enhance competitiveness, and meet the growing market demand.

Abstract

Limited technical knowledge in distillation processes and product formulation has hindered the economic optimization of lemongrass among the Tanjung Asri Women Farmer Group (KWT). This community service program aims to enhance the technical capacity of KWT members through a sciencepreneurship approach, integrating extraction, purification, and product stability processes. The methodology employed participatory training, equipment demonstrations, and hands-on production practice. Results showed a significant increase in participants' technical understanding from 72.5% to 91.3%, with 80% of participants becoming proficient in independent distillation equipment operation. The implemented process innovation successfully increased oil yield by ±20%, producing clearer and more stable essential oil. Overall, the program fostered product downstreaming and business diversification based on lemongrass essential oil as a driver for sustainable local economic development.
