Technological independence is one aspect of the challenges of the industrial revolution era 4.0. Digitalization, robotization, big data, internet of things (IoT), and efficiency of work processes require an update in technology. If everything is held in the fulfillment of practicum facilities, it will undoubtedly cost a prohibitive fee. Many of the tools and machines found in learning machining practices in Vocational High Schools (VHS) in Indonesia are still a conventional machine. This study provides a breakthrough solution in the effectiveness and efficiency of traditional machining of the lathe that starts with a preliminary identification of literature, selection according to inclusion and exclusion criteria, coding, themes classifications, and supplementary areas. Through the literature review methodology, this article has the main objective of identifying the needs in architecture and the need for supporting devices on conventional lathes based on the IoT as well as safe, comfortable, and modern work areas in lathe machining practices.

Kemajuan UMKM di Pacarejo sangat tergantung dengan kontribusi aktif dari ibu-ibu PKK. Salah satu dusun yaitu Kepuh, Desa Pacarejo, Kabupaten Gunungkidul, Daerah Istimewa Yogyakarta telah mendapatkan pedampingan intensif dari Universitas Negeri Yogyakarta. Hasil bumi Desa Pacarejo yang belum diolah secara maksimal salah satunya adalah kacang tanah. Sebagai salah satu daerah tujuan wisata, kacang tanah berpotensi diolah menjadi oleh-oleh khas dari Gunungkidul. Belum optimalnya pengolahan makanan berbasis kacang di Desa Pacarejo disebabkan oleh beberapa permasalahan yaitu permasalahan produksi, mutu produk, dan pemasaran. Program pengabdian kepada masyarakat yang dilakukan akan berfokus pada permasalahan produksi terkait produksi kulit lumpia kacang umpet, permasalahan mutu produk terkait desain packaging yang mengangkat identitas Desa Pacarejo, dan permasalahan pemasaran terkait ekspansi pasar secara luas. Tujuan Pengabdian Kepada Masyarakat antara lain: (1) meningkatkan kapasitas produksi olahan makanan “kacang umpet” di Desa Pacarejo melalui bantuan Teknologi Tepat Guna; (2) meningkatkan mutu produk dan varian rasa produk dengan menunjukan identitas Desa Pacarejo; dan (3) memperluas jangkauan pemasaran produk-produk UMKM baik di dalam dan luar DIY. Metode pelaksanaan PPM melalui empat langkah yaitu; tahap pelatihan, pendampingan, monitoring dan evaluasi. Hasil kegiatan pengabdian dapat menambah wawasan Ibu-ibu PKK dalam menambah variasi rasa olahan kacang umpet dan meningkatkan nilai jual produk.The progress of MSMEs in Pacarejo is highly dependent on the active contribution of PKK women. One of the hamlets, Kepuh, Pacarejo Village, Gunungkidul Regency, Yogyakarta Special Region, has received intensive assistance from Yogyakarta State University. One of the crops of Pacarejo Village that has not been maximized is peanuts. As a tourist destination, peanuts have the potential to be processed into typical souvenirs from Gunungkidul. The suboptimal processing of peanut-based food in Pacarejo Village is caused by several problems, namely production, product quality, and marketing. The community service program will focus on production problems related to the production of peanut spring roll skins, product quality problems related to packaging design that raises the identity of Pacarejo Village, and marketing problems related to broad market expansion. The objectives of the Community Service include: (1) increasing the production capacity of processed food "kacang umpet" in Pacarejo Village through Appropriate Technology assistance; (2) improving product quality and product flavor variants by showing the identity of Pacarejo Village; and (3) expanding the marketing reach of MSME products both within and outside DIY. The method of implementing PPM through four steps, namely; training, mentoring, monitoring and evaluation stages. The results of the community service activities can add insight to PKK mothers in adding variations in the taste of processed hide-and-seek beans and increasing the selling value of the product.

In the era of Industry 4.0, CO₂ laser cutting technology has been increasingly adopted across manufacturing, creative industries, and vocational education due to its precision, flexibility, and non-contact process. However, wood-based composites such as Medium Density Fibreboard (MDF) present challenges in laser machining, including thermal deformation, carbonization, and surface damage, necessitating further investigation into process parameters. This study designed and developed a CNC CO₂ Laser Cutting Machine with a 60 W laser source, dimensions of 160 × 100 × 85 cm, and a working area of 110 × 72 × 2 cm, integrating mechanical, optical, and control systems to improve efficiency and precision. The research method involved prototype design, fabrication, assembly, and iterative trials on acrylic, plywood, and MDF, with adjustments made to optimize power, cutting speed, and control stability. Surface roughness tests showed significant variation across materials, with MDF achieving an average Ra value of 6.25 µm (smooth) and acrylic achieving 0.85 µm (very smooth), indicating that acrylic provides superior aesthetic and precision outcomes, while MDF remains suitable for applications with moderate tolerance. The findings highlight that laser parameter optimization is critical for cut quality, and further refinements through jigs/fixtures and the addition of a rotary axis are recommended to enhance structural accuracy and expand application versatility.

Cassava is one of the commodities that is widely processed in Pagerharjo village, especially by the Madu Lestari Women Farmers Group (WFG). The problem found in WFG is that the production process of cassava chips is still done manually and has not been touched by the appropriate technology desired by KWT. This affects the capacity produced in production not much and limits labor. The purpose of this research is to explain the design process or design, explain the process of machining and test and analyze the factual capacity produced by the semi-automatic system cassava chips slicing machine. The research method used is research and development. The research process starts from observation, needs analysis, design, machine building, assembly, performance testing, data collection and analysis. Data analysis uses descriptive and quantitative theoretical considerations. The results of the study produced a cassava chips slicing machine semi-automatic system capable of producing a production capacity of 62.1 kg/h with a driving motor power of ¼ Hp.

Coffee is one of the favorite beverages enjoyed by people from all walks of life. The main challenge in the coffee bean peeling process in small and medium enterprises (SMEs) is that it is still done manually. The primary goal of creating this technological innovation is to assist workers in the production process by using appropriate technology, thereby improving the quality, effectiveness, and efficiency of their work. The design optimization and manufacturing process of the coffee pulper machine begins with literature studies, design and calculations, the fabrication of the machine, and ends with testing. The design is created using Inventor Autocad software. The coffee peeling machine measures 110 cm x 127 cm x 130 cm and is powered by a gasoline engine with an initial speed of 1800 rpm, which increases to 3600 rpm. It uses two pulleys with a ratio of 1:6, an A-75 V-belt, and a solid shaft with a diameter of 20 mm. The final result shows that the coffee pulper machine has a capacity of 610 kg per hour.
