IBNUH SYAHNI R: Rancang Bangun Alat Pencacah Jagung, dibimbing oleh ACHWIL PUTRA MUNIR dan SAIPUL BAHRI DAULAY.
Pencacahan dilakukan untuk mengecilkan ukuran biji jagung menjadi butiran-butiran dengan tingkat ketebalan tertentu agar lebih mudah diolah menjadi makanan ternak. Penelitian ini bertujuan untuk merancang, membuat, menguji serta menganalisis nilai ekonomis alat pencacah jagung. Parameter yang diamati yaitu kapasitas efektif alat, persentase bahan rusak, dan analisis ekonomi.
Dari hasil penelitian diperoleh kapasitas efektif alat sebesar 40.82 kg/jam dan persentase bahan rusak sebesar 10 %. Analisis ekonomi, biaya pokok untuk tahun pertama sampai tahun kelima berturut-turut yaitu Rp. 360,12/kg, Rp. 361,41/kg, Rp. 361,56/kg, Rp. 362,36/kg dan Rp. 363,22/kg. Break even point yaitu sebesar 8662,52 kg/tahun. Net present value sebesar Rp. 42.574.847,2 Internal rate of return adalah sebesar 47,64%.

ABSTRACT
IBNUH SYAHNI R: Design and construction of corn grater, supervised by ACHWIL PUTRA MUNIR and SAIPUL BAHRI DAULAY.
Corn grating is reduction of the size of the corn into granules with a certain degree of thickness to be more easily processed into cattle fodder. This research was aimed to design, innovate, test and analyze the economic value of corn grater. Parameters observed were the effective capacity of the equipment, percentage of damaged corn, and economic analysis.
Based on this research, it was summarized that the effective capacity of the equipment was 40,82 kg/hour and the damaged corn percentage was 10%. The economic analysis was as follows: basic costs for the first to the fifth year were Rp. 360,12 / kg, Rp. 361,41 / kg, Rp. 361,56 / kg, Rp. 362,36 / kg dan Rp. 363,22 / kg respectively. The break even point was 8662,52 kg / year. The net present value was Rp. 42.574.847,2. The internal rate of return was 47,62%.
