Judul: Desain Dan Kinerja Mesin Pemindah Bahan Pada Sistem Pengering Efek Rumah Kaca (ERK)-Hybrid Dan In-Store Dryer (ISD) Terintegrasi Untuk Biji Jagung
Abstrak: Sebuah prototipe bucket elevator sudah dirancang dan dibuat untuk pengangkutan biji jagung, sebagai bagian dari sistem terintegrasi pengering Efek Rumah Kaca (ERK)-Hybrid dan In-Store Dryer (ISD). Bucket elevator dirancang untuk mengangkut biji jagung kering dari pengering ERK-Hybrid ke ISD, dengan kapasitas1400 kg/jam, jarak vertikal 5,1 m, kecepatan sabuk 0,433 m/detik dan jarak antar bucket 0,3 m. Serangkaian pengujian dilakukan untuk mengukur kinerja dari bucket elevator seperti : kapasitas pemindahan, biji tersisa, biji rusak dan konsumsi daya listrik menggunakan tiga tingkatan kadar air yaitu 14%, 18% dan 28%. Hasil rancangan dan pengujian akan dibahas dalam tesis ini. Hasil pengujian pertama pada kecepatan putar di puli atas 92 rpm, menghasilkan kapasitas pemindahan rata-rata 612,22 kg/jam, biji tersisa rata-rata 0,27%, biji rusak rata-rata 0,1% dan kebutuhan daya listrik rata-rata 308 Watt. Karena kapasitas yang direncanakan lebih rendah dari yang diharapkan (1400 kg/jam), kecepatan putar di puli atas ditingkatkan menjadi 184 rpm. Hasil pengujian menggunakan kecepatan putar di puli atas tersebut menunjukkan peningkatan kapasitas pemindahan menjadi 945,47 kg/jam, biji tersisa 0,17%, biji rusak 0,44% dan kebutuhan daya listrik 324 Watt. Pengujian menggunakan tiga tingkat kadar air menunjukkan kadar air yang tinggi menghasilkan kapasitas pemindahan terendah, biji tersisa dan biji rusak tertinggi. Pada kadar air 14% dihasilkan kapasitas pemindahan 1000 kg/jam, sedangkan pada kadar air 18% and 28% menghasilkan kapasitas pemindahan masing-masing 630 kg/jam dan 500 kg/jam.

Abstrak: Cassava is the fourth leading commodity after rice, wheat and corn. Market demand and high productivity of cassava make it as one of the potential export commodities. In case for export or industrial use fresh cassava must be processed first into semi-finished materials for added value. It will be better if the added value is left to the farmer. For the purpose, the farmer needs to be furnished with proper and affordable technology. This study aims to design, construct and testing a dryer which apply the principle of greenhouse effect by additional heating of biomass furnace. Dryer is designed with a capacity of 180 kilograms cassava from 65% wb moisture content up to 13% wb moisture content. Drying chamber has dimensions of 2 m x 1.5 m x 2.4 m (L x W x H) with 30 shelves. This dryer has a cross flow type heat exchanger and regulating the circulation of air using a turbine ventilator. On testing with the full capacity, the dryer can dried up 180 kg cassava chips from 61.31 %wb (158.53 %db) moisture content to 9.87 %wb (11.01 %db) moisture content. On these test the dryer has a total efficiency of 18.3%, energy share of solar energy 7.72% and biomass 92.28%, drying time is 49 hours at a rate of 4.50 %db/h. While testing with half capacity, was dried 95 kg cassava chips from moisture content of 69.47%wb (232.26 %db) to 8.81 %wb (9.67 %db), the total efficiency of the dryer was 14.84% with the share of energy from solar energy 7.31% and 92.69% of the biomass, drying time required is 28 hours with the drying rate 8.56 %db/h.

Abstrak: Sulawesi has a high biodiversity of phanerogams and high degree of endemism. Phytogeographically Sulawesi is part of East Malesia; it is separated from the West Malesia by the Wallace's line. As compared to adjacent major island in Malesia, the number of bryophytes species which were found in Sulawesi is low.
