Dinamika dan perubahan yang terjadi saat ini begitu dinamis, terlebih di era revolusi industri 4.0 atau disebut sebagai revolusi digital yang diindikasikan oleh perubahan yang sangat besar di semua bidang berbasis teknologi. Perubahan juga terjadi di bidang Pendidikan yang mana dituntut dapat berjalan beriringan sesuai dengan perubahan yang ada agar dapat menghasilkan sumber daya daya manusia pendidikan tinggi yang memiliki kualitas tinggi yang juga inovatif, kreatif, dan efisien. Oleh karena itu, untuk menghadapi kondisi tersebut Kementerian Pendidikan dan Kebudayaan membuat kebijakan terkait Pendidikan diantaranya kebijakan Merdeka Belajar Kampus Merdeka (MBKM). Kebijakan MBKM memberikan kebebasan dan otonomi kepada Lembaga Pendidikan, dan merdeka dari birokratisasi, dosen dibebaskan dari birokrasi yang berbelit serta mahasiswa diberikan kebebasan dalam memilih bidang yang mereka minati. Terjadi pergeseran bentuk pembelajaran sehingga menjadi peluang dan tantangan bagi perguruan tinggi dalam memfasilitasi model pembelajaran yang mampu menghadapi tantangan jaman dan menuju kampus yang bermutu dan bereputasi.
Most of the four wheeled tractors were operated manually for many agricultural applications. Therefore the operator's fatigue during operating tractor can't be avoided. To decrease operator's fatigue it was necessary to operate tractor automatically for forward and backward motion. This research focus on the automatic backward motion and decrease turning radius by modify the brake pedal and forward-backward transmission mechanisms, which were controlled using DC motor with H-bridge actuator. Functional test was done by lifting up the tractor so that it was not move sideways while the tires were rotated. Performance test was done on the field to know the ability of the tractor to move forward and backward automatically and to know the turning radius when the left or right brake pedal was pushed down automatically. Experimental result showed that the time required to push the brake was about 0.47 s for left brake and 0.61 s for right brake. Field test result showed that the tractor was able to control automatically for forward motion with average speed of 0.62 m/s, backward motion with average speed of 0.63 m/s, to turn left with average turning radius of 2.2 m, and turn right with average turning radius of 2.4 m.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
