Abstract

A learning model known as "project-based learning" makes use of projects or activities as media. Project-based learning is used in the lecture-based lathe machining practicum course. development into the creation of a project-based learning-based textbook for student learning materials on lathe machining practicums. The steps of analysis, design, media development, expert validation, and field testing are all included in the textbook development process. The average percentage received from material expert validation was 89%, whereas the average percentage obtained from media expert validation was 90.5%. Following field testing on students participating in a lathe machining practicum and expert validation, the field trial results yielded an 88.66% percentage. Expert validation and field testing results show that the textbook fits into the very good category.

Abstract

Abstrak Tingginya jumlah penjualan kendaraan bermotor di Indonesia yang mencapai 94.067 unit pada tahun 2023 dapat menyebabkan berbagai permasalahan seperti kemacetan dan kecelakaan. Selain menimbulkan korban jiwa kecelakaan lalu lintas juga menyebabkan kerugian materi berupa kerusakan pada kendaraan seperti goresan atau penyok pada panel bodi mobil. Kerusakan tersebut dapat diperbaiki melalui proses pengecatan ulang untuk mengembalikan ke kondisi semula. Kualitas hasil pengecatan yang baik dapat dilihat dari nilai lekat dan nilai kilapnya. Nilai kilap menandakan kualitas hasil pengecatan yang dapat meningkatkan estetika dari sebuah kendaraan. Bengkel Yunex Paint yang beralamat di Desa Gesing Temanggung dipilih menjadi mitra pengabdian karena bergerak di perbaikan bodi dan pengecatan yang setiap minggunya mampu mengerjakan 2 unit mobil dengan total waktu pengerjaan 4-6 hari untuk pengecatan ulang panel bumper maupun kap mesin. Bengkel ini masih banyak menghadapi berbagai permasalahan pada  proses produksi seperti hasil pengecatan yang kurang mengkilap karena finishing masih dilakukan secara manual sehingga jumlah mobil yang dikerjakan tidak mengalami peningkatan menyebabkan perkembangan usahanya kurang signifikan. Mengatasi permasalahan tersebut maka diusulkan penerapan mesin rotary polisher yang diharapkan dapat meningkatkan efisiensi waktu dan kualitas hasil pengecatan, sehingga meningkatkan daya saing dan produktivitas Bengkel Yunex Paint. Pengabdian ini melibatkan 11 orang termasuk dengan pekerja bengkel. Metode pelaksanaan meliputi ceramah, demonstrasi, praktik langsung serta pendampingan, dan pengambilan data. Data hasil ukur daya kilap yang didapatkan yaitu 24,7 sebelum finishing, 85,3 sesudah finishing manual dan 94,1 sesudah finishing menggunakan mesin rotary polisher. Dari data yang didapatkan mesin rotary polisher dapat menambah nilai kilap hasil finishing pengecatan. Kata kunci: kualitas pengecatan; nilai kilap; mesin rotary polisher. Abstract The high number of motor vehicle sales in Indonesia, which reached 94,067 units in 2023, can cause various problems such as congestion and accidents. In addition to causing casualties, traffic accidents also cause material losses in the form of damage to vehicles such as scratches or dents on car body panels. The damage can be repaired through the repainting process to restore it to its original condition. The quality of good painting results can be seen from the adhesion value and gloss value. The gloss value indicates the quality of the painting results that can improve the aesthetics of a vehicle. The Yunex Paint workshop located in Gesing Village, Temanggung, was chosen as a service partner because it is engaged in body repair and painting which every week is able to work on 2 units of cars with a total processing time of 4-6 days for repainting bumper panels and hoods. This workshop still faces many problems in the production process such as painting results that are less shiny because finishing is still done manually so that the number of cars being worked on has not increased causing insignificant business development. Overcoming these problems, the application of a rotary polisher machine is proposed which is expected to increase the efficiency of time and quality of painting results, thereby increasing the competitiveness and productivity of the Yunex Paint Workshop. This service involved 11 people including workshop workers. The implementation method includes lectures, demonstrations, hands-on practice and mentoring, and data collection. The gloss measurement data obtained were 24.7 before finishing, 85.3 after manual finishing and 94.1 after finishing using a rotary polisher machine. From the data obtained, the rotary polisher machine can increase the gloss value of the painting finishing results. Keywords: painting quality; gloss value; rotary polisher machine.

Abstract

The traditional soybean filtration process in small- and medium-scale tofu industries remains inefficient due to labour-intensive operations, inconsistent extract quality, and high processing time. Manual pressing methods often result in reduced extract yield, uneven texture, and contamination risks. Therefore, this study aims to design and evaluate a soybean filtration machine powered by an electric motor and a low-torque gearbox, with the goal of improving efficiency, hygiene, and mechanical reliability. The research employed a Research and Development approach using the Four-D model: define, design, develop, and disseminate. A 0.5 hp electric motor was integrated with a 1:20 ratio gearbox to achieve stable rotational motion for the reciprocating filter system. The mechanical analysis indicated a total working force of 613.725 N, a motor torque of 61.37 Nm, and an output torque of 1,105 Nm after accounting for efficiency. The system demonstrated low structural deflection (0.405 mm) and a high safety factor of 3.81, confirming robust mechanical integrity. Experimental testing yielded a filtration efficiency of 93% and an average flow rate of 1.2 L/min, showing a 70–80% reduction in processing time compared to manual filtration. The feasibility assessment resulted in an 88.63% approval rating from operators, classifying the machine as highly feasible. Overall, the designed system effectively improves productivity, ergonomics, and product consistency in soybean-based food processing.
