Abstract

Panen merupakan tahap akhir dari proses budidaya padi di sawah, salah satu hal yang penting dalam pemanenan padi adalah cara panen. Cara panen dapat digolongkan dalam dua macam yaitu secara tradisional dan mekanis. Secara tradisional panen mempunyai kelemahan  dalam kebutuhan tenaga kerja yang banyak serta kapasitas kerja yang rendah sedangkan secara mekanis harga mesin panen yang mahal serta kondisi lahan pertanian di Indonesia yang bergelombang belum memungkinkan digunakannya mesin pemanen mekanis. Tujuan penelitian ini adalah merancang suatu mesin pemanen padi mekanis satu jalur yang sesuai dengan kondisi lahan pertanian di Indonesia, serta mengujinya pada lahan padi siap panen. Dari pengujian dan perhitungan didapatkan nilai tahanan guling dari mesin pemanen padi sebesar 454,133 N dan daya untuk menggerakkan mesin maju sebesar 111,01 Watt. Pada pengujian di lapang mesin pemanen padi menunjukkan unjuk kerja yang baik, dimana batang pengarah dan gigi bintang mampu mengarahkan batang tanaman padi ke titik pemotongan, dan kemampuan pisau yang dengan cepat memotong batang tanaman padi. Salah satu fungsi utama yang kurang tercapai adalah kemampuan konveyor menggeser tanaman padi ke sisi luar dari mesin pemanen. Hal ini disebabkan oleh kurangnya kecepatan gerak dari konveyor dan gigi bintang.   Kata kunci: mesin pemanen padi satu jalur, rancang bangun, mesin pertanian

Abstract

Data Envelopment Analysis (DEA) is a method for evaluating and improving the performance of organizational unit.  In this study, DEA applied to evaluate the performances of mechanized small farms in Madiun regency.  Firstly, 28 farmers that have been surveyed, were evaluated by combined DEA model which integrated all inputs and outputs sets.  Then, two different analyses which had different inputs/outputs set were established; one was cost and revenue analysis and the other was age of hand tractor analysis.  Finally, all index of efficiency in combined model and both separated models were compared.  The results revealed that 11 farmers judged efficient on combined treatment. However, on comparison of separated and combined treatment appeared that only 2 farmers were truly efficient while 9 farmers were judged partially efficient.  Two farmers were truly efficient could be the optimization benchmark in all aspect of farmers performance.  Nine partially efficient farms still had a room for improvement performances. Since inefficient farms should be motivated to achieve standard performance much higher on each aspect of performance on separated model, optimization through combined DEA way was better for 17 inefficient farmers.Keywords: data envelopment analysis, separated DEA model, combined DEA model, hand tractor, efficiency of performance, potential improvement

Abstract

Bioethanol is one alternative to fossil fuel substitutes depleting annually. Bioethanol production using waste material containing cellulose such as rice straw, require special attention in the process of pretreatment to customize the lignocellulose both in terms of structure and size to break up and reduce the content of lignin and hemicellulose. This research has been conducted on the hydrolysis of rice straw using wet milling pretreatment (WMP) and microwave-NaOH method compared to the dry milling pretreatment (DMP) with respect to the content of cellulose, hemicellulose and lignin. The results showed that the hydrolysis using WMP has a lower content of cellulose, hemicellulose and lignin compared to the DMP, since the size of the rice straw affect the mesh lignocellulose content. The larger mesh size of rice straw used, so the lignocellulose content is getting smaller.   Keywords: Bioetanol, Delignifikasi, Pretreatment, Wet Milling, Rice Straw
