Abstract

Among various types of plastic waste, used gallon containers are among the most commonly found in household environments. The implementation method used in this activity is a training method, designed to enhance the skills of the mothers who are members of the Bank Sampah Semangka 8 Ds. Tambakasri, Kec. Tajinan, Kabupaten Malang, in processing used gallons into decorative products with market value. Through material introduction, demonstrations, independent practice, and discussions, participants not only learn technical skills but also gain valuable insights into the importance of recycling. The success of this training program can be measured by several outcomes, both in the form of products created and behavioral changes among participants. After attending the training, each participant is able to create at least three types of products from used gallons. This effort is expected to create a broader impact in raising collective awareness about the importance of sustainable waste management.

Abstract

The racing cast wheel made of aluminum 6061-T6 is a critical component in motor vehicles, particularly in supporting performance, safety, and aesthetics. This study aims to analyze the mechanical performance of the wheel through Finite Element Analysis (FEA) simulation. The FEA simulation was conducted using Ansys 18.1 software with a load of 1500 N, covering both static and dynamic loading conditions. The material tested is Aluminum Alloy 6061-T6, with material properties derived from tensile testing. The simulation results indicate that maximum stress occurs in critical areas, such as bolt holes and the intersection of spokes with the wheel rim, with a maximum stress value of 46.027 MPa. This stress level remains below the material's yield strength (276 MPa), demonstrating that the design is safe from plastic deformation. The total deformation observed is 0.053 mm, which is negligible and does not affect the wheel's functionality. A safety factor exceeding 2.5 confirms that the wheel can withstand more extreme loads. Based on these findings, design optimizations such as adding fillets and surface treatments are recommended to enhance the wheel's reliability. This research provides valuable insights for the development of stronger, lighter, and more durable wheels, particularly suited to the diverse road conditions found in Indonesia.

Abstract

Aluminium alloy lebih sering digunakan dalam kehidupan sehari-hari dibandingkan aluminium murni dikarenakan sifat aluminium murni yang lunak dan tidak kuat terhadap beban berat. Pada velg mobil aluminium yang digunakan yaitu aluminium yang dicampur dengan mangan lalu dikeraskan agar kuat menahan beban yang diterima. Penggunaan aluminium alloy diperlukan proses electroplating untuk menambah ketahanan korosi, nilai decorative, dan daya tahan gesek. Penelitian ini bertujuan untuk mengetahui pengaruh jarak katoda-anoda dan waktu pelapisan pada electroplating terhadap laju deposit dan laju korosi aluminium alloy. Penelitian ini menggunakan eksperimen kuantitatif. Hasil penelitian menunjukkan adanya pengaruh terhadap laju deposit dan laju korosi aluminium alloy meskipun hasilnya tidak signifikan. Nilai laju deposit tertinggi pada kelompok electroplating dengan waktu pelapisan 30 menit dan jarak anoda-katoda 5 cm sebesar 65,1 x 10-5 gr/s, dan nilai laju deposit terendah pada kelompok electroplating dengan waktu pelapisan 60 menit dan jarak anoda-katoda 15 cm sebesar 24,1 x 10-5 gr/s. Nilai laju korosi tertinggi pada kelompok electroplating waktu pelapisan 60 menit dengan jarak anoda-katoda 5 cm sebesar 0,549 mm/year, kemudian nilai laju korosi terendah pada kelompok electroplating waktu pelapisan 30 menit dengan jarak anoda-katoda 15 cm sebesar 0,334 mm/year. Jarak katoda anoda secara parsial berpengaruh terhadap laju deposit dan laju korosi electroplating aluminium alloy.Kata kunci: Aluminium alloy; electroplating; jarak katoda-anoda;Aluminium alloy is more often used in daily life, than pure aluminium because of the soft, lightweight nature of pure aluminium. The aluminium used in the rims of cars mixed with manganese and then hardened to the weight received. Aluminium alloy required an electroplating process to enchane the durability of corrosion, structural value, dan propulsion. This study devoted to seing how distance of an anode catode and the time of extraction on electroplating the deposits and corrosion rates aluminium alloy. The study uses quantitative experiments. The results of these studies indicate an effect on deposits and corrosion rates of aluminium alloy eventhough the results are insignificants. The higher deposit rate on the electroplating with  coating 30 minutes and distance catoda anoda 5 cm is 65,1 x 10-5 gr/s, and the lowest deposit rates on the electroplating with coating 60 minutes and distance catoda anoda 15 cm is 24,1 x 10-5 gr/s. The higher corrosion rate on the electroplating with time coating 60 minutes and distance catoda anoda 5 cm is 0,549 mm/year, and the lowest corrosion rate on the elctroplating with coating 30 minutes and distance catoda anoda 15 cm is 0,334 mm/year.

Abstract

This study aims to determine the effect of self-efficacy on learning outcomes of vocational high school students in the context of implementing a competency-based curriculum. The approach used is quantitative with an ex post facto method. The study population was grade XI students of SMK Nasional Malang, with a total sample of 92 students taken (saturated sampling). Self-efficacy data were obtained through a questionnaire using a Likert scale, while learning outcome data were obtained from mid-semester report card scores. The results of the linear regression test showed that the data were normally distributed and had a linear relationship. The t-test showed that self-efficacy had a significant effect on student learning outcomes (p < 0.05). These findings confirm that self-efficacy is an important indicator in supporting the achievement of learning outcomes, especially in vocational education that demands students' independence, responsibility, and readiness to face the challenges of practice-based learning. Students with high self-efficacy tend to have better learning motivation, are able to manage learning strategies effectively, and demonstrate a high level of independence in completing assignments. Therefore, learning development in vocational high schools should not only emphasize technical aspects, but also need to strengthen students' self-confidence in achieving learning success.

Abstract

This study aims to develop a web-based instructional package integrated with the SIPEJAR platform for the Computer Aided Design (CAD) course at Universitas Negeri Malang, employing a Project Based Learning (PjBL) approach grounded in social constructivism. The development process followed the ADDIE model through the stages of analysis, design, development, implementation, and evaluation. Validation by content and media experts indicated high feasibility with scores above 85%. Implementation in a blended learning setting revealed significant improvements in students’ comprehension (from 16.7% to 73.3%), engagement (from 10% to 83.3%), learning satisfaction (from 16.7% to 76.7%), and motivation, which increased among all respondents. Findings highlight that the developed package is not only technically feasible but also enhances collaborative interaction, critical thinking skills, and student readiness for industry demands. This study contributes to contextual digital learning design in technical education and recommends broader application to similar courses along with the integration of learning analytics for continuous improvement.
