Abstract

Research has been conducted to determine the effect of biobriquette fuel types on electric power generated in miniature steam power plants. This study uses four fuels, namely raw materials for coconut shell and wood, and biobriquette from coconut shell and wood. There are two parameters tested in this study, namely the burning time and evaporation of 2000 ml of distilled water and the electric power generated. Based on research that has been done it can be concluded that the type of fuel influences the amount of power produced. From the type of fuel obtained that the greater the calorific value of a fuel, the electric power produced will be greater as well. small heating value of around 3000 cal / g, the electric power produced is getting smaller, that is equal to 0.0021 watts.

Abstract

Sub-surface analysis has been conducted to find out the lithology which includes the structure, the type of rock and the thickness of the geothermal layer of geothermal resources by using the geoelectric configuration method of Wenner-Schlumberger in Kalompie Hamlet, Galung Village, Barru sub-District, Barru District. The working principle of the geoelectric method is performed by injecting an electric current to the ground surface through a pair of current electrodes and measuring the potential difference with another pair of electrodes. The research was conducted in three trajectories with a trajectory length of 105 m and a spacing of 7 m electrodes. The result of the data interpretation was obtained by three materials that is sandy soil with resistivity value 0,095 - 4,05 Ωm have thickness 1 - 12 m, tuffed sandstone with resistivity value 4,05 - 39,7 Ωm having thickness 10 - 14 m, with a resistivity value of 39.7 - 547 Ωm with a thickness of 5 - 15 m, this rock is suspected as a rock cover on Kalompie hot water source area because it has a difficult nature to pass water (impermeabel). The geological structures of fault, anticline and syncline are not found in this research because the measurement path does not cut or pass through the path of geological structure.

Abstract

This research aims at the process of making fly ash nanosilica using ultrasonic methods and to determine the characterization of nanosilica from fly ash. Many studies have shown that fly ash contains silica. The process of extracting silica from fly ash uses the reflux method extraction process. Meanwhile, the process of making silica nanoparticles uses ultrasonic methods. The ultrasonic method is a method for breaking particles by utilizing ultrasonic waves with a high frequency that is above 20 kHz. The resulting silica was divided into three with each different treatment, namely silica without sonication (TN), silica with sonication process for 60 minutes (N60) and for 120 minutes (N120). The silica each has a percentage of elements (%) ie 23.13%, 20.25% and 17.82%.

Abstract

Research has been carried out with the title of the biobriquette quality mixture of coconut shell, corn cobs, and rice husk with sago flour as adhesive. The purpose of this study was to determine the quality of the bio-briquettes with a mixture of coconut shells, corn cobs and rice husks with sago flour as an adhesive. In this study the raw material used was coconut shell with the process of drying at temperatures of 3500C, corn cobs with a temperature of 1500C and rice husks with a temperature of 1200C with the composition used was 60%: 20%: 20%, 60%: 25%: 15%, 60%: 30%: 10% and 60%: 35%: 5% then sieving particle size for all 40 mesh samples, mixing using 3 grams of sago flour as bio-briquette adhesive, then bio-briquette printing and drying is done. Furthermore testing of compressive strength, moisture content, ash content, calorific value and combustion time with the results of compressive strength testing using the tool. TA.XTPlus Texture Analyzer the best characteristics obtained in the composition 60%: 35%: 5% with a value of 9.82 kg /cm2, and the best characteristic moisture content was tested in the composition of 60%: 30%: 10% with a value of 4.59%. The quality produced from the biobriquette mixture of coconut shell, corn cobs, and rice husk with sago flour as adhesive can be categorized as good. This is seen from the testing of water content, ash content and calorific value that meets the Indonesian national standard and the burning time of 152.18 minutes, except for compressive strength testing that does not equal to the quality standards of Indonesia.

Abstract

Springs are a problem in areas where geographic conditions are predominantly hot with low annual rainfall. Water is one of the basic needs for all living things on Earth, both plants, animals and especially humans. If there is a scarcity of spring sources, it is certain that daily activities are very disturbed. Scarcity of springs as happened in Jenetallasa Village greatly influences community activities in the Village. Prolonged drought results in increasingly severe water scarcity that occurs. Based on this problem, a field study was conducted to estimate the aquifer zone. Aquifers are a source of springs located in cavities brought under the surface of the ground which reminisce or flow. Aquifers themselves can be predicted without existence of drilling or excavation. Detection of aquifers can be done using geoelectric methods with different configurations. Our field study this time uses a schlumberger configuration with a length of 120 meters with an approximate depth of 60 meters below ground level.

Abstract

The main objective of this research is to determine the effect of molar oxides of SiO2:Al2O3 and Na2O:SiO2 to the mechanical properties of geopolymer based on laterite soil deposite Bone. Geopolymers were produced through alkali-activation method of dehydroxylation laterite. Dehydroxylation was performed by using high-temperature furnace at  for 4 hours. The chemical compositions and the microstructure properties of the starting and the resulting materials were characterized based on X-Ray Diffraction (XRD) and Scanning Electron Microscopys (SEM). Measurements of bulk density, apparent porosity and compressive strength were carried out by using Archimedes method and Universal Testing Machine. The results showed that the highest phase of the starting material was quartz (SiO2). The physical properties of geopolymers was examined from the value of their bulk density, apparent porosity and the magnitude of their compressive strength. The results showed that the value of the porosity and the density are inversely proportional, the smaller the porosity, the greater the density. The highest compressive strength value was 6.33 MPa obtained from the sample designated as K6. It was found that geopolymer based on Bone laterite exhibited good mechanical properties.

Abstract

This research aims to determine the relationship between light intensity and beam distance as the inverse square law. From the experimental results it was found that the relationship between light intensity with the distance of the beam that is the farther the distance of the beam used, the intensity of the light obtained will be smaller, and vice versa. From the results of research conducted, obtained results for an average light intensity of 2.0636 Cd.
