Abstract

Sekaran is a fairly densely populated area because it is located around the Semarang State University campus. With this dense population, culinary businesses around Sekaran are also growing. Many culinary businesses produce fried foods of various types. The problem encountered in this culinary business is that there is still a lot of oil content in the food products. This of course can harm the health of consumers. The aim of this activity is to reduce the oil content in food. The solution used is to apply an oil drainer to food products produced by culinary businesses around Sekaran. The activities carried out include: providing an understanding of the dangers of food that contains a lot of oil, providing an explanation of how to drain oil from food quickly, and providing training in the use of a drainer. The results of the activities that have been carried out are 1) providing an explanation of the function of each part of the drainer. oil in food; 2) socialize the importance of reducing the oil content in fried foods; 3) education about the effects caused by the presence of oil in food; and 4) training on how to use tools to drain oil from food has been carried out through demonstrations of tool use.

Abstract

Students’ limited understanding of lighting systems and signaling lamps is attributed to conventional teaching methods, insufficient practical tools, and the absence of interactive learning media. This study aimed to develop, assess the feasibility, and test the effectiveness of web-based interactive learning media on the subject. The method applied Research and Development (R&D) with the ADDIE development model. The research design adopted a Pretest-Posttest Control Group Design. The validation results indicated that the media was highly feasible for use, as shown by maximum eligibility scores. The effectiveness test, comparing the control and experimental groups, showed a significant difference. The improvement in students’ learning outcomes fell into the moderate category. Therefore, this learning media was proven to be both feasible and effective in enhancing students’ achievement on the topic of lighting systems and signaling lamps.

Abstract

Most students in the fashion program, particularly at SMK Negeri 6 Semarang, still show low levels of understanding regarding the principles of sustainability in the fashion industry. This is evident from the failure to meet the Learning Objective Achievement Criteria (KKTP) of 75. This condition indicates the need for more engaging, contextual, and relevant learning solutions aligned with global issues. So far, the material has been delivered conventionally through textbooks and presentations, which have proven ineffective. There is a need for the development of more engaging learning media. This study aims to assess the effectiveness of the Sustainable Fashion E-Module in enhancing student ability to analyze the fashion industries impact on the environment. The research uses a quantitative method with a pretest-posttest control group design. The sample consists of 69 students from the fashion program at SMK Negeri 6 Semarang, divided into experimental and control groups. The instruments used were pretest and posttest questions. The research data were tested for normality and homogeneity as prerequisites for analysis. Data analysis was then performed using the Normalized Gain (N-Gain) test to measure learning improvement and the Independent Sample T-Test to examine significant differences between groups. The results showed that the average N-Gain for the experimental group was 76%, categorized as effective, while the control group had only a 37% N-Gain, categorized as less effective. The T-Test showed a significance value of 0.000 < 0.05, indicating a significant difference between the two groups. Based on these findings, it can be concluded that the use of the E-Module is effective in enhancing student cognitive abilities regarding the concept of sustainable fashion

Abstract

The learning process of the motorcycle charging system at SMK Negeri Situraja still faces challenges, notably the low competency mastery of students who have not yet met the Minimum Competency Criteria. This issue arises from the limited time available for practical activities and the lack of varied and contextual teaching methods. This study aims to assess the effectiveness of the learning media, specifically a charging system simulator developed using the Project-Based Learning (PjBL) approach. The research method employed is Research and Development (R&D) with the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. The research results demonstrate that the developed simulator media is effective in improving students competency, particularly in understanding the operating principles and components of the charging system. This effectiveness is indicated by a significant improvement in learning outcomes after the simulator-based instruction. Additionally, students became more active, gained a deeper understanding of the material, and were able to apply the knowledge in independent and safe practices. The advantage of this media, compared to previous studies, is the security system that protects students during use. This feature ensures safety and creates a secure learning environment. Therefore, the PjBL-based simulator media is a suitable innovation for learning in vocational schools to support the achievement of optimal learning outcomes.

Abstract

This study aims to develop a learning application called MyLathe for eleventh-grade students in the Mechanical Engineering program at vocational high schools (SMK). The application is designed to support the discovery learning model and can be accessed via smartphones, laptops, and web platforms, enabling flexible and user-friendly learning experiences. The research employs the ADDIE development model, consisting of five phases: Analysis, Design, Development, Implementation, and Evaluation. The feasibility of MyLathe was evaluated through expert validation. Media expert validation yielded an Aiken’s V value of 0.93, while content validation scored 0.96, both indicating high validity. The reliability coefficients for both media and content exceeded 0.40, meeting acceptable standards. The effectiveness of the application was measured using an independent sample t-test, which yielded a t-value of 11.561, exceeding the critical t-table value of 1.999. This indicates a statistically significant improvement in student learning outcomes. Additionally, the N-Gain analysis showed an increase in the average pre-test score from 46.06 to a post-test score of 62.67 in the experimental class, with a comparable pre-test average of 46.84 in the control class. Practicality testing involving both teachers and students yielded a score of 92%, classified as “highly practical.” These findings suggest that the MyLathe application is a valid, reliable, effective, and practical digital learning tool for enhancing learning in machining subjects at vocational high schools.

Abstract

Perkembangan bisnis kuliner makanan di Kota Semarang berdampak meningkatnya permintaan bawang merah goreng. Permintaan bawang merah goreng juga berdampak pada produktifitas di UKM brambang goreng “Berkah Arstyaji”. Untuk meningkatkan produktifitas dan kualitasnya berdasar permitaan customer, UKM tersebut menggunakan mesin tepat guna mesin pengiris bawang merah. Namun dalam penggunaannya selama ini ternyata masih menyimpan permasalahan yang perlu upaya penyelesaiannya. Permasalahan tersebut adalah ketidak seragaman hasil irisan bawang merah yang berdampak pada kualitas bawang goreng yang tidak homogen dan produktifitasnya kurang. Ketidak seragaman hasil irisan biasannya diselesaikan dengan alat serut tangan. Hasil survey lapangan ditemukan penyebab ketidak seragaman hasil irisan bawang merah disebabkan posisi pisau pengiris yang terpasang mendatar (0 derajat) pada disk mesin, sedangkan kurangnya produktifitas karena menggunkan mata pisau tunggal. Kegiatan ini bertujuan mengembangkan mesin perajang bawang merah di pelaku UKM Brambang Goreng “Berkah Arsetyaji” Semarang. Solusi untuk mengatasi permasalahan UKM tersebut adalah mengembangkan mesin pengiris bawang merah dengan posisi sudut pisau pengiris 45 derajat, menggunakan mata pisau jamak (dua pisau), putaran motor yang dapat diatur, dan efisien listrik yang digunakan. Metode pelaksanaan yang digunakan untuk menyelesaikan permasalahan UKM Brambang Goreng “Berkah Arsetyaji” mencakupi survey lapangan, perancangan mesin, fabrikasi mesin, uji coba mesin, pelatihan, dan pendampingan. Pelaksanaan program pengabdian kepada masyarakat memberikan hasil bahwa adanya peningkatan kuantitas dan kualitas hasil irisan bawang merah yang berdampak pada peningkatan kuantitas dan kualitas brambang goreng yang dihasilkan dam pemenuhan kebutuhan customer yang terus meningkat.
