Abstract

The soil strength characteristic, which is usually e.xpressed bycohesion and internal piction, is as basic data for applying farmmachineries/equipments and farm structures. The objective of this research is to study the soil strength and density relationships of latosol and red yellowish podzolic soil. This research was conducted by standard compaction test and soil strength test (uniaxial, direct shear and triaxiul).

Abstract

AbstractThe widely sugarcane plantation area in Indonesia causes the management of sugarcane litter conducted by mechanization. To manage sugarcane litter into compost needed several machineries such as tractors,trash rakes, trailesr, choppers, trucks, composting turner, loaders, and compost applicators. The objective of this study was to design a compost applicator for sugarcane litter that can be used for a plant cane andratoon in dry land. The process of making a prototype applicators follow the design flowchart that begins with the calculation of the dimensions, design of engineering drawings, selection and material purchases. The result showed that the applicator prototype with belt conveyor metering device could function well and was able to apply the compost with a high dose (15 ton / ha).Keywords: mechanization, compost applicator, compost, sugarcane litter, sugarcaneAbstrakAreal perkebunan tebu di Indonesia yang luas menyebabkan kegiatan pengelolaan serasah tebu dilakukan dengan mekanisasi. Untuk mengelola serasah tebu menjadi kompos dibutuhkan beberapateknologi seperti traktor, trash rake, trailer, alat pencacah, truk, pengaduk, loader, dan aplikator kompos. Tujuan penelitian ini adalah merancang aplikator kompos serasah tebu yang dapat dioperasikan untuktanaman tebu baru (PC) dan tebu keprasan (ratoon) lahan kering. Proses pembuatan prototipe aplikator mengikuti alur perancangan alat yang diawali dengan perhitungan dimensi, disain gambar teknik dan pemilihan serta pembelian bahan. Hasil penelitian menunjukkan bahwa prototipe aplikator dengan penjatah tipe belt conveyor dapat berfungsi dengan baik dan mampu mengaplikasikan kompos dengan dosis tinggi (15 ton/ha).Kata kunci : mekanisasi,aplikator kompos, kompos, tebu, lahan keringDiterima: 27 November 2013; Disetujui: 19 Februari 2014
