Abstract

Sejumlah besar serasah tebu berukuran panjang berserakan di lahan setelah panen harus dibersihkan, karena mengganggu proses kerja pada musim tanam berikutnya. Penelitian ini menggunakan metode rekayasa merancang-bangun sebuah mesin pemotong serasah tebu. Hasilnya adalah sebuah unit prototipe mesin pemotong serasah tebu dengan pisau pemotong tipe reel berdimensi lebar 240 cm, panjang 268 cm dan tinggi 133 cm. Komponen pencacahnya terdiri dari silinder pencacah dengan panjang dan diameter masing-masing 60 dan 429 cm serta diameter poros silinder 45 cm. Mesin ini mampu memotong serasah tebu menjadi cacahan  kecil sebesar 2-4 cm dan langsung menguburkannya ke dalam tanah, di mana nutrisi yang masih terjandung dapat dimanfaatkan sebagai bahan kompos. Kata kunci : Serasah tebu, Rancang bangun unit pemotong serasah, Bahan kompos

Abstract

The problem of sugarcane trash after harvesting is experienced by the world's sugarcane plantations, including those in Indonesia. Large amount of sugarcane trash left in the field makes difficulties in soil management and plant maintenance. Current practice done by the sugarcane plantations was “burning before soil tillage”. However, the practice of burning cause unwanted impact to the environment and human health. Meanwhile, sugarcane trash still rich of nutrients for the land. The trash size is still long so that it should be reduced to improve composting process. The prototype was tested on 4 levels of reel rotational speeds and 4 levels of trash densities. During the tests, cutting torque and rotational speed of the reel were measured using a torque-meter and a digital tachometer. The prototype chopped up sugarcane trash of about 1.7 - 3.2 cm length. Higher trash density caused a higher cutting torque and cutting power, while higher rotational speed caused a lower cutting torque and a higher cutting power. The highest cutting torque was 4.03 kg.m, when chopped sugarcane trash of 32 kg/m3 in trash density on 400 rotational speed. Increasing the rotational speed caused a shorter trash size.
