Kinerja Traksi Model Roda Trek Bersirip Pada Tanah Lumpur di Bak Tanah
Abstract
Traktor tangan roda bersirip mengalami kesulitan saat beroperasi di sawah
berlumpur dalam. Untuk mengatasi masalah ini, roda perlu diganti dengan trek yang
memiliki bidang kontak jauh lebih besar. Untuk keperluan desain, diperlukan data
karakteristik kinerja traksi trek pada tanah berlumpur yang dapat diperoleh dengan
menguji model trek di bak tanah. Penelitian ini bertujuan menganalisis kinerja
traksi model trek bersirip pada tanah lumpur. Model trek dengan panjang 60 cm dan
lebar 20 cm diuji di bak tanah yang berisi tanah berlumpur sedalam 30 cm.
Pengujian dilakukan terhadap variasi beban vertikal 9.5, 12.5, 15.5, 18.5, dan 22.7
kg; beban horizontal 1, 2, 3, dan 4 kg; jarak antarsirip 12.70, 19.05, dan 25.40 cm;
dan tinggi sirip 5, 10, dan 15 cm. Di setiap percobaan, parameter kinerja traksi akan
diukur. Selama pengujian, dilakukan pengukuran terhadap ketenggelaman trek, slip
trek, dan efisiensi traksi. Hasil pengujian menunjukkan bahwa beban tarik dan
beban vertikal memiliki pengaruh yang dominan terhadap ketenggelaman trek, slip
trek, dan efisiensi traksi. Desain trek optimum saat trek menggunakan tinggi sirip
10 cm dan jarak antarsirip 19.05 cm dengan ketenggelaman trek 7.32 cm, slip trek
14.43% dan efisiensi traksi 68.46%. Pendugaan memiliki nilai kesalahan terendah
13.992% atau kebenaran 86.008% untuk ketenggelam trek. Hand tractors with lugged wheels have difficulty operating in the deep mud
rice fields. To solve this problem, the wheels need to be replaced with tracks that
have a much larger contact area. For design purposes, data on traction performance
characteristics of the track on muddy soil are required, which can be obtained by
testing the track model on a soil bin. The objective of this research is to analyze the
traction performance of the lugged track model on mud soil. A track model with a
length of 60 cm and a width of 20 cm will be tested in a soil bin filled with muddy
soil with a depth of 30 cm. The test will be carried out on variations in vertical loads
of 9.5, 12.5, 15.5, 18.5, and 22.7 kg; horizontal loads of 1, 2, 3, and 4 kg; distance
between of lugs of 12.70, 19.05, and 25.40 cm; and height of lugs of 5, 10, and 15
cm. In each experiment, the traction performance parameters will be measured.
During the test, track sinkage, track slip, and tractive efficiency were measured. The
test results show that the pull force and vertical force have a dominant effect on
track sinkage, track slip, and tractive efficiency. Optimum track design when the
track wheel uses a lug height of 10 cm and a distance between lugs of 19.05 cm
with a track sinkage of 7.32 cm, track slip of 14%, and tractive efficiency of
68.46%. Estimation has the lowest error value of 13.992% or accuracy value of
86.008% for track sinkage.
