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.

Abstract

The focus in this article is to reveal: (1) The purpose of participating in dual skills programs; (2) Effectiveness of In Service Training 1 (In-1); (3) Effectiveness of In Service Training 2 (In-2); (4) Competence Pedagogic and Dual Professional Teacher Skills. Dual Skills Program is the addition of assignments and functions of teachers from normative and adaptive teachers plus the task of teaching productive expertise competencies, carried out for 12 months using the On-In-On-In learning model. Type of case study research with multi-case study design. The results of this study (1) Motivation of teachers to participate in dual skills programs to obtain educator certificates and anticipate shortages of hours; (2) Implementation of In-Service Training 1 is quite effective; (3) Implementation of In Service Training 2 (In-2) is quite effective;  (4) In general On-In-On-In training is quite effective; (5) Teacher competency after training is quite good. Constraints that occur are difficult to divide the teaching time and tasks from training dual skills programs which are quite a lot. To the development of science, especially vocational education, the results of this study are expected to be used as one of the comparative studies on the theory of the effectiveness of On-In-On-In training in obtaining dual related skills: (a) The purpose of participating in a dual expertise program (b) Effectiveness of In Service Training 1 (In-1), (c) Effectiveness of In Service Training 2 (In-2), (d) Competence of Dual Skills Teachers Post-On-In-On-In Training.

Abstract

Corrosion still remains a serious problem in the application of aluminum alloys, such as Aluminum 6061, which is one of the most widely used aluminum alloys in industries because of its high strength-to-weight ratio. However, the material degrades when exposed to aggressive environments, such as acidic, alkaline, or salty solutions, and the control of corrosion has been achieved with the use of synthetic chemical inhibitors, but the increasing concern of environmental and health risks has shifted attention to more eco-friendly alternatives. The present study aimed at evaluating the efficacy of three vegetable oils (coconut oil, palm oil, and soybean oil) as environmentally friendly corrosion inhibitors for Aluminum 6061, and the alloy coupons were subjected to three different corrosive solutions (hydrochloric acid, sodium hydroxide, and sodium chloride). A quantitative experimental procedure was employed to determine the corrosion rate through the measurement of the weight loss of aluminum coupons prior to and after the immersion, and the results showed that all three oils were able to reduce the corrosion rate when compared to the samples without any inhibitor. Among them, coconut oil gave the best protection, followed by soybean oil and palm oil, because the adsorption of the organic compounds and fatty acids in the oils onto the aluminum surface formed a thin layer that separated the metal and the corrosive environment. Consequently, the results also showed that the use of bio-based oils can be a promising alternative to synthetic corrosion inhibitors in industries that use aluminumbased materials.

Abstract

Penelitian ini bertujuan membandingkan efektivitas model Team-Based Project (TBP) Cyberpedagogy dan TBP Konvensional dalam mengembangkan critical thinking dan kreativitas mahasiswa pada pembelajaran di Pendidikan Teknik Mesin. Desain penelitian ini menggunakan kuasi eksperimen dengan dua kelompok: kelas eksperimen yang menerapkan TBP berbasis teknologi digital (cyberpedagogy), dan kelas kontrol yang menggunakan TBP konvensional. Data dikumpulkan melalui instrumen skala Likert yang telah divalidasi. Uji normalitas (Kolmogorov–Smirnov) dan homogenitas variansi (Levene’s test) menunjukkan data berdistribusi normal dan homogen. Hasil uji independent samples t-test menunjukkan nilai rata-rata critical thinking pada kelompok eksperimen sebesar 44,88 dan kontrol 43,60 (p = 0,646), sedangkan kreativitas eksperimen 42,29 dan kontrol 41,12 (p = 0,673). Seluruh nilai signifikansi 0,05, sehingga hipotesis nol diterima—tidak terdapat perbedaan yang signifikan antara kedua model pembelajaran terhadap critical thinking dan kreativitas mahasiswa. Temuan ini mendukung teori “using knowledge” dalam model Dimensi Belajar Marzano, bahwa penerapan TBP cyberpedagogy maupun konvensional sama-sama mampu mengaktifkan habits of mind di lingkungan belajar kolaboratif, selama desain proyek dan aktivitas pemecahan masalah terkelola dengan baik.
