Abstract

ABSTRAKPendidikan 4.0 merupakan paradigma pendidikan masa depan, dimana pembelajaran cybergogy yang diterapkan. Pembelajaran ini  memerlukan teknologi digital dan internet dalam penerapannya. Salah satu teknologi digital tersebut adalah video pembelajaran. Salah satu SMK Negeri di Kabupaten Tegal siap mendukung pendidikan 4.0 dengan menerapkan pembelajaran interaktif dengan menggunakan video. Tujuan dari pengabdian ini yaitu untuk meningkatkan keterampilan digital guru produktif SMK.. Ada 3 tahapan dalam pengabdian ini yaitu persiapan, pelaksanaan, dan evaluasi. Tahap persiapan dilakukan dengan (1) mengumpulkan informasi situasi di SMK, (2) mengatur waktu dan tempat pelatihan, dan (3) mempersiapkan alat dan bahan yang akan digunakan saat pelatihan, lembar kuesioner dan soal pretest & posttest. Tahap pelaksanaan menggunakan beberapa metode, yaitu ceramah, demonstrasi, dan praktik langsung. Evaluasi dilakukan dengan memberikan pretest dan posttest, mengisi kuesioner kebermanfaatan pengabdian, dan pengamatan selama proses pelatihan. Hasil pengabdian ini menunjukan bahwa pelatihan ini diadakan pada tanggal 27 Juli 2023 dengan jumlah peserta 15 guru dapat meningkatkan pengetahuan peserta pelatihan dari 56,00 menjadi 77,33 dari skor maksimal 100. Selama proses pelatihan peserta pelatihan termotivasi. Peserta pelatihan merasa sangat puas dengan pelatihan yang dilakukan. Kata kunci: pendidikan 4.0; SMK; video pembelajaran; youtube ABSTRACTEducation 4.0 is a future educational paradigm, where cybergogy learning is applied. This learning is not only assisted by digital technology but uses the internet in its use. One of these digital technologies is learning videos. One State Vocational School in Tegal Regency is ready to support education 4.0 by implementing learning using videos. The purpose of this service is to improve the productive digital skills of SMK teachers. There were 3 stages in this service, namely, preparation, implementation, and evaluation. The preparatory phase was carried out by (1) gathering information on the situation at the SMK, (2) arranging the time and place for the training, and (3) preparing the tools and materials to be used during the training and the pretest & posttest sheets. The implementation phase used several methods, namely lectures, demonstrations, and direct practice. Evaluation was carried out before, during and after the activity by providing pretest and posttest, observing during the training process, and assessing the performance of the trainees. The results of this service showed that this training held on July 27 2023 with a total of 15 teachers participating can increase the training participants' knowledge from 56.00 to 77.33 from a maximum score of 100. During the training process the training participants were motivated. The training participants were very satisfied with the training carried out.. keywords: education 4.0; learning video; vocational high school; youtube

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.
