Abstract

Rice mills produce abundant husk waste. The husks are used as a mixing material for bricks because they are flammable and have capability to form hot coals with high calor. This potential is used to develop the husks into briquettes. This study used rice husks (oriza sativa) and flamboyant pods (Royal ponciana) as the main ingredients for forming briquettes. This pods was chosen because had not optimally used. The composition of rice husk briquettes and flamboyant fruit skins made of 16.7%: 83.3%, 33.4%: 66.6%, 50%: 50%, 66.6%: 33.4%, 83.3 %: 16.7%. The briquettes formed were measured the calorific value, mass reduction using the TGA (Thermogravimetric analysis) thermal measurement method, and measured the values ​​of moisture, ash, volatile, and fixed carbon content. The results of the measurement of the lowest calorific value in rice husk briquettes were 83.3% with a value of 4,551 cal / gram, while the highest value was 5,945 cal / gram in rice husk briquettes percentage of 16.7%. The result of TGA measurement of the largest mass reduction was briquettes with a percentage of husk 83.3% having the highest mass reduction of 11.1 mg. The results of the measurement of water content obtained 7.04%, 24.70% volatile, 9.98% ash content, 58.28% fixed carbon

Abstract

Head bushing is part of the plastic sack-making machine components that process works always have friction between the bushing head cham causing wear and tear. This wear and tear leads to further damage to the components - components other spare parts. Head material is nylon pure solid has a melting point 350-425 ° C, but was unable to maintain its shape because happen frictions during the process of making plastic sack. Research to make head bushing by adding the powder of wood Ulin (Eusideroxylon Zwageri) as reinforcements and to do wear and tear. The results obtained show. that the optimum value of the powder composition wood ulin is 4% , with value of wear and tear 0,0544 mm/h with a time 96 hours 29 minutes 29 seconds. But overall, the addition powder of wood Ulin, cannot be used as ingredients of make head bushing, because value of wear and tear of head bushing without additive of powder of wood Ulin, more smaller than head bushing with additive powder wood Ulin.

Abstract

lectric furnace atau tungku listrik adalah peralatan pemanas yang menggunakan sumber panas dari listrik. Electric furnace konvensional yang ada sekarang terkadang kurang akurasi dalam proses waktu maupun suhu. Tujuan penelitian ini adalah membuat mesin electric furnace berbasis mikrokontroler dengan fungsi utama proses pemanasan lebih akurasi terjaga waktu dan suhu dan dapat di atur secara otomatis serta di monitor melalui LCD (Liquid Crystal Display). Metode yang dipakai adalah perancangan awal sekaligus pembuatannya dan pengujian untuk uji kinerja rangkaian kelistrikan, uji kecepatan pencapaian suhu, dan uji perpindahan panas dengan melakukan pengukuran suhu dari suhu dalam electric furnace hingga suhu permukaan luar pelat. Perhitungan perpindahan panas dimulai dari dalam dinding electric furnace, batu tahan api (refraktori), pelat besi dan suhu lingkungan dengan panas yang dihasilkan dari elemen listrik berkapasitas 4400 Watt. Diperoleh hasil electric furnace dengan dimensi ruang tungku ukuran 190 mm x 350 mm x 320mm. Uji coba kinerja rangkaian kelistrikan furnace, di coba pada suhu 800 ˚C di tahan selama 30 menit, hasil yang diperoleh suhu tetap konstan 800˚C. Uji kecepatan untuk pencapaian suhu, electric furnace mampu bekerja hingga tempertur maksimum 1000 ˚C, dengan kecepatan untuk pencapaian suhu 1000 ˚C selama 17.111 detik atau 47,5 jam dengan rata-rata kenaikan suhu tiap 1˚C adalah 0,1 detik, Laju perpindahan panas total pada dinding electric furnace adalah 6,83W/m2K.
