Abstract


Abstract
Paddy field soil condition is an important factor to be considered in designing a lug wheel for paddy field cultivation. To get the optimum wheel design, the wheel traction performance should be predicted before constructing the wheel. The purpose of this research were 1) to develop a prediction method of lug wheel performance, 2) to analyze the performance of lug wheel, and 3) to select the best configuration of lug wheel design. Tractive performance prediction method was developed based on the forces acting on
active lugs when the wheel operates in the soil. Soil reaction forces to wheel lugs were predicted using measured data of soil resistance on plat penetration in the soil. Nine wheel designs were tested in a paddy field to validate the prediction of wheel traction performance. The results showed that the developed
prediction method developed had not approached the wheel traction efficiency maesurement results. The wheel traction efficiency prediction showed a high level of error that was more than 65%. The best wheel design for the paddy field was determined from the highest average measurement value of the wheel traction efficiency i.e 47.81%, that was the wheel with 12 lugs and 30° lug angle.


Abstrak
Kondisi lahan sawah merupakan faktor penting yang perlu dipertimbangkan dalam perancangan roda besi bersirip untuk pengolahan tanah. Untuk mendapatkan desain roda besi bersirip yang optimal, kinerja traksi harus diduga sebelum melakukan perancangan. Tujuan dari penelitian ini adalah 1) untuk mengembangkan sebuah metode pendugaan kinerja traksi roda besi bersirip, 2) untuk menganalisis kinerja
traksi roda besi bersirip, 3) untuk menentukan konfigurasi desain roda besi bersirip terbaik. Metoda untuk menduga kinerja traksi dikembangkan berdasarkan gaya-gaya reaksi yang bekerja pada sirip aktif pada saat roda besi bersirip beroperasi di lahan. Gaya reaksi tanah pada sirip roda diduga dengan menggunakan data pengukuran tahanan tanah terhadap penetrasi plat. Sebanyak 9 buah tipe desain roda besi bersirip telah diuji pada lahan sawah untuk memvalidasi hasil pendugaan kinerja traksi roda besi bersirip. Hasil validasi menunjukkan bahwa efisiensi traksi hasil pengembangan metode pendugaan belum mendekati hasil efisiensi traksi pengukuran. Pendugaan efisiensi traksi roda besi bersirip menghasilkan tingkat error yang tinggi yaitu lebih dari 65%. Desain roda besi bersirip terbaik untuk lahan sawah ditentukan dari ratarata nilai efisiensi traksi hasil pengukuran tertinggi sebesar 47.81% yaitu roda besi bersirip dengan jumlah
sirip 12 dan sudut sirip 30°.
