Abstract

An electric motor is a device that converts electrical energy into mechanical energy. One of its  important components is the armature which functions as the center of movement. Armature is paired with another component of electric motor. In order to achieve a good quality of electric motor, armature quality must be controlled through a standard experiment called balancing test. An adhesive material called putty will be added into armature if the balancing test result is not up to standard. This study conducted in one of automotive industry in Indonesia. The company face a problem in balancing test process. Putty addition carried by factory workers only based on their estimation, resulting in the mass of putty used not in accordance with predetermined standards and also inconsistent, so that the balancing process takes a long time. This research offer a solution for the problem, i.e. putty dispenser to replace the manual putty-picking process with a standardized semi-automatic one. The research objective is to analyze the quality and productivity of the putty dispenser tool design in the armature balancing process. Through 100 armature samples consist of type A and type B, this study examines the quality of the putty mass provided using the most frequently occurring value and uses the independent T-test method to examine the hypothesis that there is a real difference in cycle time before and after the putty dispenser tool. Frame strength testing was also carried out using Solidworks software simulation with 632 N loading. The results of the research on the putty dispenser tool are that the frame used is proven safe, a decrease in cycle time with a percentage of 34.16%, an increase in productivity of 34.13%, also improved quality through the aspects of %NG reduction of 42.29%, and a standardized and constant putty mass of 100 mg for armature type A and 200 mg for armature type B.

Abstract

This study explores how SDGs-integrated Problem-Based Learning (PBL), supported by Repong Damar ethno-comics, contributes to the development of students’ critical thinking and sustainability awareness. A quasi-experimental approach with a non-equivalent control group design was applied to two tenth-grade classes at Senior High School Perintis Bandar Lampung selected purposively. Students’ critical thinking was assessed using essay tests, while sustainability awareness was measured through questionnaires. The findings revealed a statistically significant difference between groups (p < 0.05). The experimental class demonstrated a higher N-gain (0.64, moderate) compared to the control class (0.47, moderate). In addition, sustainability awareness in the experimental group reached a high category (85.8%). These results highlight the potential of combining SDGs-oriented PBL with culturally relevant media to create meaningful learning experiences that support both cognitive and sustainability-related competencies. Integrasi SDGs dalam Problem-Based Learning Berbantuan Etnokomik: Pengaruhnya terhadap Keterampilan Berpikir Kritis dan Kesadaran Keberlanjutan Siswa ABSTRAK: Penelitian ini mengkaji peran pembelajaran Problem-Based Learning (PBL) terintegrasi SDGs yang didukung etno-komik Repong Damar dalam mengembangkan keterampilan berpikir kritis dan kesadaran keberlanjutan siswa. Metode yang digunakan adalah kuasi eksperimen dengan desain non-equivalent control group pada dua kelas X SMA Perintis Bandar Lampung yang dipilih secara purposive. Data keterampilan berpikir kritis diperoleh melalui tes esai, sedangkan kesadaran keberlanjutan diukur menggunakan angket. Hasil penelitian menunjukkan adanya perbedaan signifikan antara kedua kelompok (p < 0,05). Kelompok eksperimen memiliki nilai N-gain lebih tinggi (0,64, kategori sedang) dibandingkan kelompok kontrol (0,47, kategori sedang). Selain itu, tingkat kesadaran keberlanjutan pada kelompok eksperimen berada pada kategori tinggi (85,8%). Temuan ini menunjukkan bahwa integrasi PBL berbasis SDGs dengan media kontekstual berbasis budaya lokal mampu memberikan pengalaman belajar yang bermakna serta mendukung pengembangan kemampuan kognitif dan kesadaran keberlanjutan siswa.

Abstract

Digital transformation in higher education has encouraged the use of web-based learning media that can integrate teaching materials, learning activities, and evaluation in a single accessible platform. This study aimed to develop PhytoAction, a Wix-based website employing the Problem-Based Learning (PBL) model integrated with Sustainable Development Goals (SDGs) 13: Climate Action, for the Plant Physiology course. The research followed the Lee and Owens (2004) five-stage development model consisting of analysis, design, development, implementation, and evaluation. Data were collected through validation sheets completed by material experts, media experts, and education practitioners, as well as student response questionnaires during one-to-one, small-group, and field trials. Results showed that the website obtained a "very valid" category from material experts (96.22% before revision, improving to 100% after revision), media experts (92.75% before revision, improving to 96% after revision), and practitioners (97.38%). Practicality trials also indicated a "very practical" category, with average scores of 91.52% (one-to-one trial), 90.06% (small-group trial), and 87.03% (field trial). These findings suggest that PhytoAction is a valid and practical learning medium that can support more contextual, flexible, and student-centered learning in the Plant Physiology course.
