Abstract

Potensi pemanfaatan pangan lokal berupa jagung harus di budidaya guna mengantisipasi masa transisi pandemi Virus Corona 19 yang makin mengedihkan, sehingga perlu menciptakan mekanisme teknologi tepat guna dalam mengolah pangan lokal bagi masyarkat dalam meningkatkan kwalitas dan kwantitas konsumsi pangan jagung selama masa transisi pandemi. Hasil aneka olahan jagung dapat memperkuat ketahanan pangan lokal ini dengan bermacam-macam hasil olahan jagung seperti, jagung bose, jagung katemak, jagung titi dan nasi jagung.umumnya pembuatan jagung bose secara manual dengan cara menumbuk biji jagung didalam wadah (lesung) selama waktu 14 menit sehingga timbul gesekan antara poros, lesung dan biji jagung dalam lesung guna mengeluarkan kulit ari biji jagung. Mesin ini dapat di desain dengan ukuran panjang 1350 mm x lebar 500 mm x tinggi 1100 mm, diameter poros engkol pengerak mekanisme pengupas 80 mm serta diameter poros pengupas 110 mm. Motor penggerak dengan daya dari perhitungan sebesar 154.8 Watt, dengan kecepatan putaran poros engkol 350 Rpm dan kecepatan poros pengupas 123 m/sec dengan tegangan gesek poros pengupas sebesar 16 N/m untuk menggerakkan mesin pengupas kulit ari jagung dengan kapasitas 5 kg.

Abstract

Student satisfaction is a critical indicator for maintaining the competitiveness and reputation of higher education institutions. To ensure continuous improvement and meet student expectations, this study aims to evaluate student satisfaction within the Faculty of Engineering at a higher education institution by analyzing service quality gaps using the Partial Least Squares - Structural Equation Modeling (PLS-SEM) method. Five service dimensions—Tangible (physical facilities), Reliability (dependability), Responsiveness (promptness), Assurance (staff competence), and Empathy (personalized care)—were assessed through quantitative questionnaires and qualitative data. The analysis results indicate that Tangible, Responsiveness, Assurance, and Empathy have a significant influence on student satisfaction, while Reliability does not show a meaningful effect. The model demonstrates a substantial ability to explain the variation in student satisfaction and shows good predictive relevance. Based on these findings, strategic recommendations are proposed to enhance physical facilities, improve service responsiveness, strengthen staff competence, and adopt more personalized service approaches to bridge the gap between student expectations and actual experiences. These insights provide a solid foundation for improving academic and administrative services, thereby contributing to better educational outcomes and enhancing the institution’s overall competitiveness.

Abstract

The objective of this training is to enhance the proficiency of high school/vocational high school teachers in the creation of technical drawings using Autodesk Inventor, a software that is utilized for 3D modeling, structural strength simulation, motion animation, and other engineering analyses. The Faculty of Engineering, Darma Persada University conducted this training on February, both online and offline. The training method encompasses theory, direct practice, and evaluation through pre-tests and post-tests. The results of the training demonstrated a decrease in the teachers' comprehension of the fundamental concepts and the application of Autodesk Inventor in engineering education. The documentation and evaluation of this program can serve as a reference for the development of similar training in the future.

Abstract

This community service program was designed to strengthen the capacity of teachers and lecturers in utilizing advanced prompting techniques based on Artificial Intelligence (AI) to support instructional innovation. The focus of the training was on two effective methods Chain of Thought (CoT) and Role Prompting which enhance human-AI interaction in educational contexts. The activity was conducted through face-to-face workshops involving 25 participants from various educational institutions, combining theoretical explanations, hands-on practice, and case-based discussions. Participants learned how to construct structured and contextual prompts for teaching applications such as lesson planning, explanation of concepts, and simulation-based learning. Evaluation results showed a significant improvement in participants’ understanding and ability to apply prompt engineering strategies, as reflected in both assessment scores and the quality of practical outputs. The program also contributed to raising awareness about ethical AI usage in education and emphasized the role of digital literacy in enabling educators to adapt to the demands of digital transformation.

Abstract

Mastery of technical drawing is an important skill in the world of education, especially in the field of engineering, including for high school teachers or equivalent who teach vocational fields such as mechanical engineering, automotive, and machining design. AutoCAD Mechanical as a Computer-Aided Design (CAD) software provides various features that facilitate the creation of technical drawings according to international standards. This community service activity aims to improve teachers' competency in creating technical drawings using AutoCAD Mechanical, so that they can integrate these skills into the learning process. The training was attended by 20 teachers from various vocational and general high schools. The implementation method included material delivery, demonstrations, and direct practice with instructor guidance. The results of the activity showed that 85% of participants were able to create 2D and 3D technical drawings according to ISO standards with an accuracy level above 90%. This training is expected to improve the quality of learning in schools, so that graduates have engineering design competencies relevant to industry needs
