Abstract

This study aims to determine the physical quality of the alternative fuel used oil waste generated by the distillation process and to know how big the resulting efficiency distillation apparatus for the purification process used oil waste . This research was conducted by first designing a simple distillation apparatus and then burning twice with such a simple distillation apparatus . After the burning process is done testing the quality of the physical form of the density, viscosity and caloric value that previously had to be done first physical quality testing on used oil with the same parameters. The results obtained for each parameter before and after distillation is to density (860-864 kg/ ) and (760-761 kg/ ); for viscosity (20°C = 0,8374176,743 Poise, 40°C = 124,445 Poise, 60°C = 15,995 Poise); and (20°C = 0,8374 Poise, 40°C = 0,7268 Poise, 60°C = 0,3273 Poise); and to the calorific value (1.483 J) and (1.542 J). The results showed that the density parameter for testing and quality standards ( specifications ) of gasoline fuel . While testing the viscosity parameters and quality standards ( specifications ) type fuel kerosene . And to the calorific value obtained does not meet the standards and quality ( specifications ) of any type of fuel , but approaching the calorific value of the fuel type of gasoline.

Abstract

Energy in general is an activity or effort or work that can be done by certain forces such as electricity, heat, gravity, mechanics, chemistry and so on. The composition of Indonesia's energy currently derived from petroleum by 52.50%, amounting to 19.04% of natural gas, coal amounted to 21.52%, water by 3.73%, geothermal by 3.0%, and new energy by 0.2%. Electrolysis is an example of an alternative energy source. It uses an electrolyte solution to produce electricity, which is a solution capable of generating electricity. The solution usually comes from acidic fruits such as starfruit and lime. The study aims to know the potential for electrical energy that is generated, to know the intensity of the voltage that is generated, to know the current of acidity and to know the acidity of the acidification. This type of study is a quantitative study with the research method used, which is a method of experimentation. From this research, the results show that the starfruit solution has a pH of 0.40 with a voltage of 0,9 V; 1.7 V; 2.2 V and produces an electric current of 0.03 mA; 0.15 mA; 0.58 mA. The resulting lime solution has a pH of 1,39 with a voltage of 1 V; 1.8 V; 2.6 V and produces an electric current of 0.15 mA; 0.38 mA; 0.61 mA. Based on this research, it can be seen that starfruit and lime can be used as an electrolyte solution to produce electrical energy.

Abstract

This research was conducted at the hospital. Level II Pelamonia Makassar South Sulawesi. Formulation of research problems, namely (1) determine the ratio between the pressure fluid infusion and blood pressure for patients with discharge or severe nutrition in children, adults and the elderly, and (2) determine the flow rate of fluid infusion for patients experiencing discharge or severe nutrition in children children, adults and elderly. In this study the parameters under study is a comparison of blood pressure measured by a sphygmomanometer with intravenous fluid pressure in pediatric patients, the mature and elderly, as well as the flow rate of fluid infusion for pediatric patients, adults and the elderly who experience severe fluid and nutrients. Comparison of the patient's blood pressure and infusion pressure and flow rate of intravenous fluids known through calculation of several variables that have been measured and calculated. The results showed that (1) measured blood pressure values corresponding with the calculated pressure fluid infusion in pediatric patients, adults and the elderly based on the events of osmosis and (2) the flow rate of intravenous fluids to children gained an average of 6.669×10-9 m3/s (on the calculation of Q = A.v) or an average of 5.558×10-9 m3/s (on the calculation Q = V/t), while adults and the elderly gained an average of 2.001×10-8 m3/s (calculation result Q=Av) or 1,667×10-8 m3/s (on the calculation Q=V/t). This means that the flow rate of fluid infusion for pediatric patients less than the infusion flow rates for adults and the elderly.

Abstract

This research was conducted Alla district, Enrekang regency. This study aims to isolate or zoning areas prone to landslides using GIS software and identify the causes of landsileds using the wenner-schlumberger configuration geoelectric method in Alla District, Enrekang Regency. Data processing method used is res2dinv software for geoelectric data and arcgis software for mapping and required parameters such as rainfall, slope, geomorphology, soil type and geology. Based on the results obtained by using GIS application by overlapping land type map, geology, slope slope, geomorphology and rainfall, then obtained landslide inecology rate in the research area namely for low inecology rate with an area of 12% spread percentage, for moderate inewanity rate with an area of 57% dispersal percentage and for high inwant rate with an area of 30% spread percentage. Results obtained using geoelectric methods found the discovery of a potential landslide slip field. This guessing is due to the three layers in the research area there is a slip field with a resistivity value of 29.7 Ωm – 37.9 Ωm. The data of the research results using GIS application is reinforced by the data of previous research by using geoelectric methods in Pana village of Alla District Enrekang Regency Keywords: SIG, Landslide, Geoelectric, Software Arcgis.

Abstract

This study aims to determine how the effect of varying the color of LED light on the  content of carotenoid red spinach and green spinach, and to know what color produces the highest amount of carotenoids, therefore conducted research by giving 3W LED lighting with the brand sunfree lamp for 12 hours at night in open spaces with red, green, yellow and without lights with a distance of about 7cm for red lights, for green lights with a distance of 14 cm and yellow lights with a distance of 23 cm from the surface of spinach. With the intensity of the lamp 180 lux. Spinach used in this study was red spinach and green spinach. The variables measured in this study were the number of spinach leaves measured every week with temperatures ranging from 22-32 °C. Measurements were made every 7 days (every Friday). Based on the results of the activity, it can be concluded that the effect of light coloration on the levels of red spinach carotenoids on green light is very influential because the highest number of carotenoids is 123.11 μmol / L, because green light has the smallest wavelength of 495-570 nm and has the biggest photon energy is 2.17-2.50 eV. Whereas in the past green green spinach has the smallest amount of carotenoids caused by the color equation which makes the pigment or carotenoid small with carotenoid amounts of 68.46 μmol / L.Keywords: Red spinach, green spinach, UV-vis spectrophotometer, light

Abstract

Fever was a condition where the body temperature was above 37,5oC. Fever was also part of the immune process that was fighting infections due to viruses, bacteria and parasites. Fever was considered very high and potentially dangerous if the temperature reaches 39oC. This research used experimental of temperature Cobra3 method. The research showed  thermophysical values of kapok leaves, red betel leaves and hibiscus flower leaves as ingredients for fever compresses. The results of kapok leaves were the average specific heat value of 45.07 (J/groC), and heat capacity value of 901.30 (J/oC). For the sample of red betel leaves, the average specific heat value were 72.50 (J/groC) and heat capacity value 1,540 (J/oC). Sample of hibiscus flower leaves were the average specific heat value 96.30 (J/groC) and the heat capacity value 1,925.3 (J/oC).
