Abstract

This study focused on variation of buffer distance as well as different shaft materials and 3 loading of test specimens. Obtained from the test results on the aluminum shaft at a buffer distance of 60 cm the largest vibration value occurs on the x axis of 17.8 mm/s and the largest deflection occurs at 0.45 m with a weight of 0.135 kg is 0.044 m. Experiment using a buffer distance of 80 cm the largest vibration value occurs on the z axis of 12.6 mm / s and the largest deflection value occurs at 0.6 m with a weight of 0.135 kg is 0.046 m. Experiment using a buffer distance of 100 cm the largest vibration value occurs on the z axis of 14.9 mm/s and the largest deflection occurs at a distance of 0.75 m with a weight of 0.135 kg is 0.088 m. Tests on the stainless steel axle at a buffer distance of 60 cm the largest vibration value occurs on the z axis of 24.1 mm/s and the largest deflection value occurs at a distance of 0.45 m with a weight of 0.135 kg is 0.0037 m. Test uasing a buffer distance of 80 cm the largest vibration value occurs on the x axis of 22.6 mm/s and the largest deflection value occurs at a distance of 0.6 m with a weight of 0.011 kg is 0.046 m. Pada jarak penyangga 100 cm nilai getaran terbesar terjadi pada sumbu z yaitu 14,2 mm/s dan nilai defleksi terbesar terjadi pada jarak 0,75 dengan berat 0,135 yaitu 0,057 m. Testing on the copper shaft at a buffer distance of 60 cm the largest vibration value occurs on the x axis of 20 mm/s and the largest deflection value occurs at a distance of 0.45 m with a weight of 0.135 kg is 0.0032 m. Experiment using a buffer distance of 80 cm the largest vibration value occurs on the x axis of 15 mm/s and the largest deflection value occurs at a distance of 0.6 m with a weight of 0.135 kg is 0.017 m. Test using a buffer distance of 100 cm the largest vibration value occurs on the x axis of 12 mm/s and the largest deflection value occurs at a distance of 0.75 m with a weight of 0.135 kg is 0.119 m.

Abstract

Abstrak. Algoritma Dijkstra merupakan algoritma yang dipakai dalam penentuanlintasan terpendek dari suatu titik tertentu ke setiap titik lain pada suatu graf. Lin-tasan terpendek untuk suatu titik tertentu dengan titik lainnya diperoleh dari pohonpembangun yang memiliki nilai minimum. Pada makalah ini akan dibahas teori darialgoritma Dijkstra serta penerapannya dalam menentukan lintasan terpendek.Kata Kunci: Pohon pembangun, algoritma Dijkstra, lintasan terpendek
