Abstract

Transplanter padi merupakan metode penanaman padi
dengan menggunakan mesin modern yang bertujuan agar proses
penanaman lebih cepat dan efisien. Berbeda dengan penanaman bibit adi secara konvensional dimana penanamannya dengan menabur benih bibit padi setelah lahan dibajak atau tanpa mesin. Mesin transplanter memiliki beberaa kelebihan diantaranya yaitu proses tanam lebih cepat, dapat menjangkau area tanam lebih luas, mengurangi jumlah tenaga kerja, mudah dalam pengoerasian, serta jarak tanam dapat ditentukan dan seragam. Di Indonesia saat ini sudah banyak petani yang memanfaatkan teknologi mesin transplanter dan banyak yang sudah merasakan manfaatnya. Pada mesin transplanter terpasang banyak komponen salah satu yang paling krusial yaitu poros lengan penanam. Dimana poros lengan penanam tersebut memiliki putaran yang paling tinggi diantara komponen yang lainnya. Selain itu, poros tersebut juga bekerja dengan menerima beban berupa puntir, lentur, tekan dan tarikan seperti roda gigi,
bearing dan lengan penanam. Sehingga menjadi penting dalam
proses perancangan pada poros tersebut agar poros tersebut
beroperasi denga aman. Dengan memanfaatkan perkembangan
teknologi, pada penelitian ini akan dilakukan simulasi pada poros lengan penanam dengan material poros AISI 1035 menggunakan software simulasi elemen hingga. Kelebihan ini dapat meminimalisir biaya untuk uji eksperimen di laboratorium. Kemudian dilakukan perhitungan safety factor dan distribusi xi tegangan yang dialami pada poros sehingga diketahui letak kritis pembebanan poros rice transplanter machine. Dalam penelitian ini dimensi dari poros adalah berdiameter 15 mm dimana terdapat beberapa komponen pada poros diantaranya dua buah bearing, satu roda gigi, dan dua lengan penanam. Berdasarkan hasil simulasi didapatkan nilai tegangan maksimum poros sebesar 62,8 N/mm2, sedangkan untuk tegangan displacement maksimum poros tersebut senilai 0,07 mm. Berdasarkan hasil simulasi dapat disimpulkan bahwa poros tersebut dikategorikan aman karena tegangan maksimum poros lebih kecil dari tegangan ijin bahan. Selain itu, terdapat perbedaan nilai antara perhitungan manual dan hasil simulasi. Dimana perbedaannya sebesar 1,2%.

Rice transplanter is a method of rice planting using
modern machines that aim to make the planting process faster and more efficient. In contrast to conventional planting adi seedlings where planting by sowing rice seed seeds after the land is plowed or without machinery. Transplanter machine has several advantages including faster planting process, can reach a wider planting area, reduce the amount of labor, easy in the matching, and planting distance can be determined and uniform.
In Indonesia today there are many farmers who utilize the
technology of transplanter machines and many who already feel the benefits. In the transplanter machine installed many components one of the most crucial is the shaft of the grower's arm. Where the shaft of the grower's arm has the highest rotation among the other components. In addition, the shaft also works by accepting loads in the form of twists, bending, presses and pulls such as gears, bearings and grower arms. So it becomes important in the design process on the shaft so that the shaft operates safely. By utilizing the development of technology, in this study will be conducted analysis on the arm shaft grower with shaft material AISI 1035 using software simulation elements up. This advantage can minimize the cost for experimental tests in the laboratory. Then the calculation of safety factor and voltage
distribution experienced on the shaft so that it is known the critical location of loading the rice transplanter machine shaft.In this study the dimensions of the shaft were 15 mm in diameter where there were several components on the shaft including two bearings, one gear, and two planting arms. Based on the simulation results obtained the maximum voltage value of the shaft of 62.8 N / mm2, while for the maximum displacement voltage of the shaft is worth 0.07 mm. Based on the results of the simulation it can be concluded that the shaft is categorized as safe because the maximum voltage of the shaft is smaller than the material permit voltage. In addition, there is a difference in value between manual calculations and simulation results. Where the difference is 1.2%.
