Abstract

Trains are a means of transportation of interest to the public in Indonesia. In addition to fast, the cost and convenience of service on the train became one of the reasons for the selection of this transportation. Accidents at railway crossings are common in Indonesia. One reason is the absence of a doorstop in the railway crossing. In this research, we try to develop the closing and opening tool of train railway crossing automatically. This device is equipped with vibration sensor and infrared sensor to detect train arrival. The sensor readout signal will be processed by arduino UNO and sent to the control center using wireless nRF24l01 + PA + LNA module. The signal will be received by the control module using the same receiver module and will be processed by arduino mega 2560 to open and close the railway crossing door equipped with LED indicator. Based on the test results, the nRF24l01 + PA + LNA transceiver module can work at a distance of 940 meters with an average data transmission delay of 1.2952 seconds.

Abstract

Fusel oil is a side product of ethanol manufacturing process through the fermentation of molasses. Sometimes, fusel oil is accidently mixed with liquid waste from the bottom of alcohol rectifying column. This mixture is called lutter washer. Fusel oil contains isoamyl alcohol, n-amyl alcohol, and other alcohols. Isoamyl alcohol is the raw material of organic ester. Further processing is required to increase the economic value of fusel oil, such as the separation of components by distillation. In this study, the composition of isoamyl alcohol and n-amyl alcohol in the residue in the distillation process as a function of distillation time in a packing column was evaluated. An artificial waste lutter washer was used as a raw materials in this experiment. The processes were conducted using a distillation column with a cylindrical dan spherical glass packing materials. Lutter washer was distilled with total reflux until the equilibrium temperature was reached, then the data of the experiment was taken during 180 minutes at the condition of reflux at 5/5 (5 minutes distillate was returned to the tower and 5 minutes distillate was collected). The composition of the distillation residue were evaluated at interval time of 30 minutes. The same processes were evaluated using different heights of packing materials. The data show that the highest composition of isoamyl alcohol and n-amyl alcohol are 21.99% and 3.70% of the 15 mL total residue, respectively. It is obtained in the distillation process that used the packing materials with ball shape, the column with 85 cm of height and 3.5 cm of diameter.

Abstract

This research investigates  stressed sheeting welded (SSW) effects of stiffened thin plate structure with preheat temperature  variations. Stiffened thin plate structure is a structure that  consists of frame and sheet that used on  vehicle structure because of requirement low volume materials. The principle of  SSW is installation of sheeting on the frame is done by pulling the sheeting in hot conditions so the sheeting after joined with the frame has the flat surface. Lap joints of  SS 400 with thickness of  1 mm dan 3 mm were made using Gas Metal Arc Welding. The preheat temperature that used were 50°C, 60°C and 70°C. The mechanical properties were measured with respect to strength and hardness while physical properties were examined based on the distortion, micro and macrostructure. Results show that the distortion of weld metal with preheat temperatures 50°C, 60°C and 70°C are 1.02; 2.06; and 2.22 mm respectively. This values is better than weld metal without  SSW that has distortion 3.02 mm. The tensile  strength of weld metals with SSW method  is 20% higher than the weld metal  without SSW. Ferrite and pearlite structure appeared in based metal and HAZ region while weld metal had acicular ferrite and grain boundary ferrite structure.

Abstract

Preparations and modifications of Ni-Mo/natural zeolite and Mo-Ni/natural zeolite catalysts as well as their characterizations had been carried out. The preparations of catalysts were carried out by reacting a natural zeolite produced in Wonosari with the precursor of Ni(NO3)2.9H2O and Mo(NH4)7.6H2O. The modifications were performed by varying the rasio of Ni/Mo whereas the Mo was previously loaded to the zeolite or Mo/Ni ratio whereas the Ni was previously loaded and the total metal content was 1 wt.% based on the zeolite. The aim of this research for the fututure is to prepare catalysts with high acidity and crystallinity for the conversion of waste plastics fraction to gasoline fraction (C5-C12 hydrocarbons).    The characterization of catalysts included determination of metal content using Atomic Adsorption Analysis (AAS), acidity by adsorption of ammonia or pyridine vapour  base method, and crystallinity by X-ray Diffraction (XRD). The treatment of catalysts using Etilene Diamine Tetra Acetic acid  (EDTA) was performed to study the metal distribution on the outer or inner surface of the zeolite.    The characterization results showed that the loading of Ni and Mo to the zeolite produced higher acidity catalysts than those of monometal loaded catalysts. The increase of Ni loaded caused the decrease of catalysts acidity, on the other hand, the increase of Mo loaded caused the increase of catalysts acidity. The metals loaded on the zeolite were distributed inside the pore and at outer surface of the zeolite. For all catalyst samples, the acidities determined using ammonia were higher than those of pyridine, and the acidities determined before the EDTA treatment was lower than those after the treatment.  The metals loading on the zeolite did not defect its crystallnity. Metal contents of the zeolite before the EDTA treatment were higher than those after the treatment. The relationship between the metal ratios towards the catalyst acidity was varying. The EDTA treatment to the zeolite sample enhanced the crystallinity of the sampel. Catalyst samples produced in this research have high acidities and crystallinities, thus promisingly can be used for conversion process of waste plastics to gasoline fraction.  Keywords : natural zeolite, acidity, Ni-Mo/natural zeolite, Mo-Ni/natural zeolite, crystallinity, EDTA
