Abstract

Essential oil distillation has been carried out from the lemongrass material using two heaters there are rice husk and heating mantel. In comparison ingredients (lemongrass: water = 0.125 kg: 0.5 liters) distillation with rice husk heater requires energy 6022.5 kcal, 3660 second distillation time, costs Rp 912.5 with an average rendemen of oil produced 0.0635 %. Distillation with the same material amount using heating mantel requires the energy 832.143 Kcal, distillation time 6990 seconds, the cost Rp 608.6 and producing the rendemen 0.114%. Distillate debit is influenced by the heat generated which produced by the rice husk and heating mantel. The quality of lemongrass oil which produced by the rice husk heating is better than the heating mantel in term of the lemongrass oil color and oil refractive index. Lemongrass oil which is produced by the pale brown of heating rice husk and refractive index values were in the range of 1.4830 to 1.4890. Keywords: rice husk, heating mantel, distillation, lemongrass oil, energy.

Abstract

Ferroelectric material originating from Barium Strontium Titanate (BST), is expected to have high energy because it has a dielectric constant and high charge storage capacity [6]. Materials produced by the process of ferium dopan, it is hoped will be a temperature sensor. If, materials BST and BFST (Barium Ferium Strontium Titanate) subjected to the temperature (material change that temperature), and the resulting voltage, then this material can be applied as a temperature sensor using a microcontroller. Microcontroller that used is ATMega 8535 with internal ADC. Voltage was generated, will be reinforced with a voltage amplifier (OpAmp) and will be processed into digital data at the ATMega8535 internal ADC (Analog Digital Converter).Incoming digital data will be processed and displayed in the view Microcontroller-based desktop applications Delphi 7. The material to be tested is material BST, BFST 5%, and BFST 15%.   Keyword: BST, Temperature sensor, ATMEGA 8535, ADC, Delphi 7

Abstract

Has done growth Ba0,25Sr0, 75TiO3 (BST) thin film and BST are pure Ferium Oxide Fe2O3 dopant (BFST) with dopant variations 5%, 10% and 15% above the substrate Si (100) type-p using Chemical Solution Deposition Method (CSD) with the spin coating technique at a speed of around 3000 rpm for 30 seconds. BST thin films made with 1 M concentration and annealing at a temperature of 850°C for Si Substrate. Thin film on silicon substrate type-p thickness characterization performed using the volumetric method and the characterization of electrical conductivity by using LCR meter. From the characterization results showed the thickness increases with the addition of ferium oxide dopant given. Electrical conductivity value of BST and BFST thin films are in the range semiconductor materials and electrical conductivity values obtained increased when the higher intensity light is used whereas resistance value could decrease if the light intensity is increased. The addition of ferium oxide dopant will increases electrical conductivity value of BST and BFST thin films.   Keywords : BFST, thin film, CSD, spin coating, electrical conductivity

Abstract

Rice husk furnace  is a technology based on local wisdom to anticipate threats crisis energy. At first investigated husk stoves for cooking only in the scale of the household, but today rice husk furnace developed for industrial scale because of the importance of commercial aspects of a very promising from this rice husk furnace. In rice husk furnace also developed an industrial scale boiler system, boiler systems where it can enlarge its efficiency, in the midst of a boiler chimney pots have used, because basically rice husk furnace process is influenced by air flow. Husk furnace efficiency greatly affect the number of furnace ash which is required in the cooking process.   Keywords: rice husk, rice husk furnaces, air flow, efficiency, boilers.
