Abstract

This study aimed to assess the effectiveness of using YouTube Channel videos as a learning tool, with a specific focus on tire changing and wheel balancing content, to enhance student learning outcomes and prepare them for the Vocational Competency Exam at Vocational High Schools. The research was conducted at Dharma Bahari Vocational School in Surabaya, where blended learning was adopted in response to the COVID-19 pandemic. The research utilized a quantitative descriptive research design, incorporating response questionnaires from both students and teachers, as well as cognitive, affective, and psychomotor assessment instrument sheets. Data collection included questionnaires, tests, and observations, followed by quantitative descriptive analysis. The findings of the study indicated a significant positive impact of using YouTube Channel video media on student learning outcomes. This impact was evident through the noteworthy difference in student learning outcomes before and after the intervention. The significance value (p-value) in the t-test was 0.000, falling below the probability threshold of 0.05, signifying a substantial difference in the learning outcomes of students who utilized YouTube Channel video media. In conclusion, this research affirms that YouTube Channel can effectively serve as a supportive tool in blended learning and as a means of preparing students for vocational competency exams. as a result, the recommendation stemming from this research is to continue harnessing YouTube Channel video media for learning purposes and to explore the development of video content relevant to other materials.

Abstract

Permasalahan dalam penanganan sampah mendorong munculnya berbagai inovasi mesin pencacah sampah organik berskala industri dengan alokasi biaya yang cukup besar. Penelitian ini bertujuan untuk merancang mesin pencacah sampah organik multifungsi berkapasitas 54 kg/jam, yang dapat digunakan untuk mencacah sampah organik dengan menyesuaikan kapasitas rumah tangga. Metode dalam penelitian ini yaitu research and development, dimulai dari observasi, studi literatur, desain alat, hingga uji coba fungsi mesin. Mesin dirancang dengan dimensi 30 cm x 24 cm x 120 cm yang beroperasi pada kecepatan 1415,1 rpm dan membutuhkan daya sebesar 372,54 Watt serta menghasilkan torsi 2,514 Nm. Mesin ini menggunakan desain pisau dynaflow pada blender yang dapat dilepas pasang dengan variasi 4, 8, hingga 12 mata pisau. Pengujian mesin menggunakan sampah sayur atau buah yang dicampur air dengan perbandingan massa 1:1 (2,7 kg sampah dan 2,7 liter air) dengan waktu pencacahan 3 menit. Hasil pencacahan terbagi menjadi dua bentuk, yakni hasil pencacahan yang melewati saringan dengan diameter ≤ 5 mm dengan tekstur lebih cair dan hasil pencacahan > 5 mm yang bertekstur lebih padat. Hasil pencacahan pada mesin pencacah sampah organik ini dapat digunakan sebagai pakan ternak maupun diolah menjadi pupuk cair.

Abstract

Educational staff, commonly referred to as administrative human resources, play a critical role as strategic assets in supporting the success of higher education institutions, including at the Vocational Faculty of Surabaya State University (Unesa). Institutional performance and service quality are closely linked to the competence and performance of these educational staff. Therefore, systematic training and development efforts are essential to enhance their competencies in line with the dynamic needs of the institution. One effective approach to designing relevant and impactful training programs is through Training Needs Assessment (TNA), which serves as a critical initial step in the training design process. TNA helps to identify gaps between existing competencies and future institutional demands, ensuring that training programs are targeted, responsive, and aligned with both institutional strategic objectives and individual performance improvement. This study aims to design a comprehensive training and development model for educational staff at the Vocational Faculty of Surabaya State University, based on a structured TNA process. The TNA will adopt both macro and micro approaches, mapping institutional-level needs as well as job-specific and individual performance gaps. The expected output is the development of an up-to-date, data-driven training and development model that can serve as a strategic reference for preparing faculty development plans and academic texts in the future, ensuring the sustainable improvement of educational staff competencies and institutional performance

Abstract

Sepeda listrik roda tiga merupakan alternatif transportasi ramah lingkungan yang memerlukan sistem suspensi optimal untuk meningkatkan kenyamanan dan keamanan pengendara di jalan Indonesia yang masih banyak rusak dan bergelombang. Penelitian ini bertujuan menganalisis fenomena keterbatasan sistem suspensi pasif sepeda listrik roda tiga Aviator AT 230 terhadap pencapaian standar kenyamanan dan keamanan khususnya pada kondisi jalan bumpy. Metode penelitian dilakukan secara eksperimental berbasis simulasi menggunakan pemodelan quarter-car dan software MATLAB/Simulink dengan memvariasikan tiga mode kecepatan (Eco, Normal, Sport) pada profil jalan bumpy. Model matematis dibangun berdasarkan parameter kendaraan dan dianalisis untuk menghasilkan nilai RMS (Root Mean Square) percepatan vertikal sesuai Standar ISO 2631-1:1997. Hasil analisis menunjukkan bahwa semua kombinasi mode kecepatan menghasilkan RMS percepatan di atas 1,25 m/s² yang dikategorikan sebagai sangat tidak nyaman menurut Standar ISO 2631-1:1997, dengan peningkatan signifikan sebesar 265% dari mode Eco ke mode Sport. Selain itu, defleksi suspensi pada semua mode kecepatan tetap dalam batas aman secara struktural. Temuan ini membuktikan bahwa sistem suspensi pasif Aviator AT 230 memiliki keterbatasan dalam menjamin kenyamanan optimal, meskipun aman secara struktural. Penelitian ini merekomendasikan penggunaan mode Eco pada jalan gunduk untuk meningkatkan kenyamanan pengendara dan memberikan dasar bagi pengembangan strategi optimasi suspensi yang lebih adaptif di masa mendatang.
