This research is related to making a web to display data on CO, CO2 and temperature monitoring results in real time. The measuring instrument used consisted of an MQ-7 sensor to detect CO gas, a MQ-135 sensor to detect CO2 gas, a DHT-22 sensor to measure the temperature and a microcontroller as a control system. CO, CO2 and temperature measurements were carried out at the University of Lampung with 10 different points. Measurements were made for three days in the morning, afternoon and evening with the duration of measurement of each location 5 minutes. Measurement data is displayed on the PC server using an interface created through the Visual Basic 2010 program and saved to the Mysql database. Data from the database is sent to the web server. Based on the results of tests conducted, the web monitoring system is running well. The web can display CO, CO2 and temperature measurement data in the form of graphs and tables in real time. The web can be accessed by web browser at devices that are connected to the internet.

This research was conducted to determine the effect of sintering time on the formation of the superconducting phase BSCCO-2212 by calculating the level of purity of the phases formed and looking at the microstructure. The variation of sintering time was 10, 20, 30 and 40 hours using the wet mixing method. The sample was calcinated with 800 °C for 10 hours and sintered with 830 °C. The XRD’s characterization result shows a decrease in phase purity with increasing the sintering time. The relative high volume fraction of the BSCCO-2212/ts10 sample is 90,48% while, the lowest volume fraction of BSCCO-2212/tc40 is 50,74%. The relative high orientation degree of BSCCO-2212/ts20 is 18,47% and the lowest orientation degree of BSCCO-2212/ts10 is 8,4%. The SEM’s characterization result shows of all samples have been oriented and have relatively little space between slabs (voids).

The Research about the design of high temperature helium gas-cooled reactor (HTGR) terraces with thorium fuel recycled using the SRAC program has been completed. This research includes the percentage of fuel enrichment, reactor core size, reactor core configuration, criticality, and the distribution of the power density. The calculation of reactor core is done in two dimensions \sfrac{1}{6} hexagonal terrace section with a triangular mesh. The fuel is used, i.e. thorium with a burn-up of 20 GWd/t and 30 GWd/t, and helium gas as a cooler. The results obtained in this study show that the ideal HTGR reactor core design with reactor core size and configuration are (x) 22 cm at point (y) = 2035,05 cm and at (y) 11 cm at point (x) = 2035,05 cm, then enrichment in fuel 8%. The result of maximum power density is 550.3685 Watt/cm3 where the position at (x) = 22 cm and axis (y) = 11 with the effective multiplication factor value keff of 1,0000002.

This study about burn up calculations on the HCLWR reactor with two dimensional hexagonal geometric models of uranium using SRAC COREBN has been carried. This study used uranium-235 and uranium-238 as the fuels, light water as coolant and moderator. The calculation was done with computational simulation of COREBN. The calculation aims to produce a conversion ratio more than 1 and a critical multiplication factor (keff). The research used fuels enrichment, burn up period, burn up step, linier power and volume fraction parameters. The percentage of enrichment from U1 and U3 were 3% and U2 was 2,5%. The volume fraction of each material was 52% fuels, 12% cladding, and 36% coolant, the reactor operating period for 548 days with 6 step of burn up then the reactorpower is 2400 MW and the linear poweris 1,792722 MW/cm. The calculation of conversion ratio was 1,01233 and keff was 0,901.

This research Coal is one of the sedimentary fossil fuels that can ignite, is formed from organic sediment, and the remains of plants are then formed through the process of coalification. The main element consists of carbon, hydrogen, and oxygen. The formation of coal has certain conditions and only occurs in certain eras throughout geological history. The carbon age was approximately 340 million years ago. In the Permian Age or the Paleozoic era, 270 million also formed the most productive coal which is almost the entire coal deposit (black coal) in other parts of the earth. In this study we conducted at the Laboratory of PT. Bukit Asam tbk. Observation Results in the Study of Average Volatile Matter 19.11, Max Volatile Matter value 38.34, Min Vollatie Matter value 11.34. And the Average Calorie Result of 7578.5 Kacl / Kg, Max Calorie Value of 8046 Kcal / Kg. In this study, it was proved that coal samples were Anthracite types.

Bio-battery is defined as an energy storage device where the energy source comes from organic compounds. The electrical characteristics of the bio-battery can be obtained using to copper (Cu) and zinc (Zn) electrode pairs. Cassava pulp is used as the electrolyte. Cassava pulp is being fermented for 48 hours, 96 hours, and 144 hours and added 4% formalin. The electrolyte cell consists of 20 cell batteries in series with each mass is ±30 grams. The electrical characteristics of fermented cassava pulp are measured with 4 watts LED load and without load. The results show that the highest voltage is 20.66 V which is obtained by 144 hours fermented cassava pulp. The electrical characteristics in this research tend to constant due to the addition of preservatives (formalin).
