So far, the rural population of fuel users make firewood stoves from ground or cement. Often waiting is made less efficient and produces a lot of smoke pollution, especially if the level of dryness of the wood is low. From this background, then came the idea for the manufacture of stoves that save fuel wood and minimal smoke pollution. Furthermore, to be able to achieve this goal, in this study a biomass furnace will be developed that has a combustion air regulation system and a firewood drying system before use. Research implementation is divided into furnace design (design and fabrication) and testing (combustion characteristics and performance). Research begins with the design of the dimensions and shape of the furnace to be made. Furthermore, fabrication of stoves from Stainless Steel plate materials will be carried out at the Mechanical Technology Laboratory, IST AKPRIND. The stove produced by the construction will be tested with fuel wood in terms of combustion characteristics and performance. The results show that biomass stoves can be used and produced for household and small-scale industries.

A simple thermal and catalytic degradation of polyethylene plastic waste has been carried out to produce alternative liquid fuel. Plastic of 1500 grams was pyrolyzed at a specific temperature of 450 °C. The gases were condensed in a water-cooled condenser and collected in a liquid container. Energy balance calculation was done where catalytic cracking with Y zeolite as catalyst seemed to be the best because the generated thermal energy from waste plastic oil was already higher than the required electric energy supplied for the cracking. However, several improvements must always be made in order to save more energy and create the best result for commercialization.

Pattern making in sand casting requires high-level skilled workers since accuracy is the most important concern in producing good quality products. Therefore, conventional pattern-making becomes a major obstacle in developing new products, especially for complicated products as it takes over 70% of the total time in production of the foundry process. This study offers an alternative method in pattern making utilizing 3D technology with the Fuse Deposition Material (FDM) method. It consisted of three steps: planning, production, and evaluation. An intake manifold is an example product that was designed by using Computer Aided Design (CAD) and then imported to a slicer application to obtain the G codes. After the design was printed by using filament of PLA+, it was assembled to create the plate pattern that then was used to produce the intake manifold through casting. The study result shows that the FDM method of the 3D printing technology is feasible for pattern making on sand casting. Deviation and shrinkage of the casting product were still within tolerance. The largest shrinkage is 0.453 mm (1.258%).

The demand for increasingly diverse product designs and specifications in the manufacturing industry requires Computer Numerical Control (CNC) machine operators to have high technical skills and strong self-efficacy and creativity. High self-efficacy allows operators to be more confident in applying their technical skills, while creativity helps them solve problems and challenges during the production process. This study aims to improve students' self-efficacy and creativity by applying the Peer-Project Based Learning (Peer-PjBL) model, which combines aspects of project-based learning with peer-to-peer learning. The method used in this research is Classroom Action Research (PTK), which consists of two implementation cycles. Each cycle involves planning, implementation, observation, and reflection stages. The subjects of this study were 20 students who took the CNC Machining Technology course at Universitas Negeri Yogyakarta. Data were collected using a questionnaire that measured self-efficacy and student creativity indicators and then analyzed descriptively. The results showed that applying the Peer-PjBL method significantly increased students' self-efficacy and creativity in each research cycle. This improvement can be seen in students' ability to face new challenges independently, as well as their ability to generate diverse creative ideas in solving problems. This research makes an important contribution to the development of learning methods in vocational education by emphasizing the improvement of technical abilities and non-technical skills, such as self-efficacy and creativity, which are needed in the modern world of work.

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.
