Abstract

Penelitian ini dilakukan untuk menganalisis pengaruh variasi konsentrasi campuran jembatan garam terhadap karakteristik elektrik 5 buah sel galvanis seri menggunakan elektroda Cu(Ag)-Zn dengan beban 20 LED. Variasi konsentrasi campuran jembatan garam menggunakan alumina 0,1 dan 1 mol, kalsium karbonat 0,1 dan 1 mol pada semen dengan menggunakan air laut sebagai pelarut. Monitoring tegangan dan arus pada sel galvanis menggunakan sensor INA219 sedangkan monitoring intensitas cahaya menggunakan sensor BH1750 secara real-time. Hasil penelitian menunjukkan bahwa semakin besar konsentrasi alumina pada jembatan garam akan semakin besar nilai tegangan yang dihasilkan. Nilai hambatan dalam sel galvanis akan semakin kecil apabila konsentrasi jembatan garam kalsium karbonat memiliki nilai kecil.

Abstract

Research on laboratory room security system has begun to be developed with various kinds of inputs used. In this study, the design of a laboratory room security prototype with automatic doors has been realized using the MLX90614 temperature sensor based on Arduino Atmega 2560. The design of this prototype aims to design a prototype laboratoey room with automatic doors using a door lock solenoid and a temperature sensor MLX90614. In addition, this system is equipped with a counter to reduce and add people in the room using the FC-51 infrared sensor. Data retrieval is done by detecting human temperature before entering the room, when the temperature input is met, the door of the room will open with a maximum limit of 10 people. The results showed that the system was functioning properly, indicated by the state of the door that could open when it received an input of temperature between 35-37°C, the door remained closed when detecting of temperature other than 35-37°, and the door remained closed when the object in the room was up to 10 people.

Abstract

The research was conducted to determine the effect of sintering temperature on the level of purity of the superconducting phase BSCCO-2212 and BPSCCO-2212 using the wet mixing method. Sintering was carried out for 20 hours with variations in sintering temperature: 825, 830, 835 and 840°C. XRD results showed that the phase purity level increased until it reached the optimum point at 835°C sintering temperature and then decreased at 840°C. The highest volume fraction of the BSCCO-2212 sample was obtained at a sintering temperature of 835°C at 71.09% and the highest degree of orientation was obtained at a sintering temperature of 830°C at 26.44%. In the BPSCCO-2212 sample, the highest volume fraction was obtained at a sintering temperature of 835°C at 52.59% and the highest degree of orientation at a sintering temperature of 830°C at 43.49%. The results of the comparison of BSCCO-2212 and BPSCCO-2212 samples showed that the BPSCCO-2212 sample had a higher level of phase purity than BSCCO-2212.

Abstract

Synthesis and characterization of rice husk and asphalt silica composites was carried out with a ratio of 85%: 15%. Silica synthesis from rice husk was carried out by the sol-gel method. The materials used in this study were rice husks, asphalt, distilled water, gasoline, NaOH and HNO3. Then the silica and asphalt according to the comparison is set at 110oC. This study aims to look at the structural characteristics, functionality and physical properties, namely water content and thickness development of the sample. Based on the research that has been done, it can be concluded that from the results of XRD characterization the samples have silica and amorphous carbon structures, then based on FTIR characterization shows the -OH (hydroxil) functional groups occur at wave number 3524 cm-1, the hydroxide metal Si-OH (silanol) is oxidized into Si - O - Si and Si - O are formed at wave numbers 1084 cm-1, 810 cm-1 and 462 cm-1 and the formation of the C-H and C=O function group occurs at wave numbers 2923 cm-1 and 2361 cm-1. Then test the physical properties of the water content of 7.642% with a change in thickness development of 4.783%.

Abstract

Research has been carried out on the synthesis of nanotitania by hydrothermal as a function of temperature. The purpose of this study was to determine the effect of temperature on the phase formation, structure and particle size of TiO2 using the hydrothermal method with TiOSO4 as the main ingredient. In this study, using temperature variations of 150, 200, 250 and 300°C and samples were characterized using X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The phases formed are the anatase and rutile phases which have a tetragonal structure and the hilly phase with an orthorhombic structure. The rutile phase appeared predominantly in each sample and the sulfuric phase only appeared at 250ºC. The anatase phase obtains a particle size of 10-18 nm, where the higher the temperature, the bigger the particle size. Furthermore, the rutile phase obtained a particle size of 14-25 nm, where the higher the temperature, the smaller the particle size.
