ABSTRAKTatanan pendidikan pasca mewabahnya covid-19 mengalami perubahan yang cukup signifikan. Dunia Pendidikan juga dituntut untuk bisa bersahabat dengan jarak. Dalam pendidikan yang serba terbatas ini pembelajaran daring menjadi satu-satunya pilihan demi terus berlangsungnya usaha mencerdaskan anak bangsa. Pembelajaran daring yang dapat dilakukan salah satunya yaitu dengan pembelajaran daring berbasis vinesa yang dikembangkan oleh Universitas Negeri Surabaya. Metode yang digunakan dalam penelitian ini adalah penelitian kuantitatif dengan pendekatan deskriptif. Penelitian ini mengumpulkan dan menganalisa data langsung yang berasal dari responden sebagai user vinesa kemudian dianalisis dan divalidasi menggunakan metode trianggulasi untuk mendapatkan data yang valid. Penelitian ini menunjukkan bahwa pembelajaran daring berbasis vinesa sangat mudah dan memiliki tampilan yang cukup baik, memiliki tools yang mudah dipahami user, Serta memiliki berbagai macam media materi yang menarik. Namun demikian vinesa juga memiliki kekurangan yaitu penggunaanya cukup memerlukan kuantitas kuota yang cukup banyak Kata Kunci: Pembelajaran Daring, Vinesa, Pendidikan Teknik Mesin. ABSTRACTThe educational structure after the Covid-19 outbreak underwent significant changes. The world of education is also required to be friendly with distance. In this limited education, online learning is the only option for continuing efforts to educate the nation's children. One of the ways to do online learning is by using vinesa-based online learning developed by the State University of Surabaya. The method used in this research is quantitative research with a descriptive approach. This study collected and analyzed direct data from respondents as vinesa users then analyzed and validated using the triangulation method to obtain valid data. This research shows that vinesa-based online learning is very easy and has a pretty good appearance, has tools that are easy for users to understand, and has a variety of interesting media materials. However, Vinesa also has a disadvantage, namely that its use requires quite a large quantity of quota.. Keywords: Online Learning, Vinesa, Mechanical Engineering Education
One of the causes of air pollution today is the increasing use of motorized vehicles. The use of technology has also been pinned on many wrong vehicles to improve the quality of the exhaust emissions that have been produced. One of them is EFI (Electronic Fuel Injection) technology which has been embedded in many vehicles. The component that has an effect on improving the quality of exhaust emissions at EFI is an electronic fuel pump. The fuel pressure on the electronic pump can be adjusted manually. This study aims to determine changes in fuel pressure on exhaust gas emission levels. This research uses an experimental method, where the fuel pressure is varied from the pressure of 50psi, 40psi, 30psi and 20psi, and the engine speed is varied from 800rpm, 1500rpm, 2250rpm, 3000rpm and 3750rpm. The results of the data obtained are analyzed using the quantitative description method. The test results showed that there was a decrease in the lowest CO level of 0.663% at 30psi fuel pressure with 3750rpm engine speed. HC also experienced a decrease, the lowest decrease was obtained in the value of 280ppm at 20psi fuel pressure and 3750rpm engine speed. While CO2 has increased, the highest increase of 13.33% was achieved at 20psi fuel pressure and 3750rpm engine speed.
The objectives of this study are: (1) creating an augmented reality (AR) application in the form of a press machine; (2) testing the attractiveness of the technology developed; and (3) testing the effectiveness of AR technology in the form of press machines. The method used is research and development (R&D). The final stage of product development is to carry out quasi-experiments. The phase is focused on all vocational students at Malang State University. The findings in this study include: (1) AR-shaped press machine that was developed proved to have a high level of design attractiveness and material; (2) AR shaped press machine that was developed proved effective in increasing student’s basic understanding of the competence in understanding the function of press machine components; and (3) all results in this study are expected to be the main reference in the development of AR technology for learning.
In this industrial revolution 4.0 era, professional science, technology, engineering, and mathematics (STEM) bachelor must have various skills. One of which is problem-solving skills. The development of problem-solving skills (PSS) is very important in higher education. Students must have PSS that must be improved to become excellent graduates, including physics bachelor candidates. Many physics bachelor candidates lack problem-solving skills. This problem is the basis for developing innovative learning models based online that, by design, can improve the problem-solving skills of physics bachelor candidates in the COVID-19 pandemic. This research aims to analyze the effectiveness ORNE learning model in improving the problem-solving skills of physics bachelor candidates as an alternative to online learning in the COVID-19 pandemic. The research design used a true-experiment with a non-equivalent control group design with 58 physics bachelor candidates. Data collected using the problem-solving skills test and then analyzed using the Paired Sample Test, Effect Size, N-gain, and Independent Sample Test. The results showed that the ORNE learning model proved effective in improving physics bachelor candidates' problem-solving skills. This research implies that the ORNE learning model can improve physics bachelor candidates' problem-solving skills as an alternative to online learning in the COVID-19 pandemic.
Desa Rejosari Kecamatan Gondang, Kab. Tulungagung terdapat beberapa pelaku Usaha Kecil Menengah (UKM) yang memproduksi tempe, namun sudah bertahun-tahun berjalan tetapi tidak ada perkembangan yang signifikan baik dari segi omset, proses produksi, manajemen dll, sehingga TIM Pengabdian Kepada Masyarakat (PKM) hadir untuk membantu permasalahan yang dihadapi pelaku usaha tempe di Desa Rejosari yang dalam hal ini bertindak sebagai mitra. Berdasarkan hasil diskusi dengan mitra terdapat dua permasalahan urgen yang harus diselesaikan untuk mencapai tujuan tersebut, yaitu (1) permasalahan aspek produksi, yakni rendahnya kualitas dan kuantitas produksi pengupasan kulit kedelai yang masih dilakukan secara manual dan (2) permasalahan aspek manajemen, yakni lemahnya pengelolaan manajemen UKM tempe, khususnya manajemen produksi dan manajemen keuangan. Solusi untuk menyelesaikan kedua permasalahan tersebut adalah: (a) penerapan mesin pengupas kulit ari kedelai yang efektif dan efisien, dan (b) Melakukan kegiatan diskusi, pelatihan dan pendampingan. Metode pelaksanaan program PKM ini dilakukan dengan tahapan: (1) menentukan permasalahan prioritas (2 )Penentuan metode kegiatan, (3) perancangan mesin (4) Manufaktur (5) Uji coba mesin, (6) penerapan mesin, (7) Pelatiahan Pengoprasian mesin, (8) Pelatihan Manajemen Usaha, dan (9) Pemantauan dan pendampingan. Hasil pelaksanaan program PKM adalah: (1) penerapan 1 unit mesin pengupas kulit kedelai kering yang efektif dan efisien dengan kapasitas produksi minimal 250 kg/jam, (2) terjadinya perubahan penerapan manajemen usaha yang lebih baik, khususnya manajemen keuangan, (3) pendapatan pengusaha kecil tempe meningkat, (4) masih tersedia banyak waktu bagi UKM tempe untuk melakukan aktivitas produktif lain.
