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

The research on corrosion rate analysis of concrete iron with swampsoil medium has been conducted. The aims of this study were to determine thecorrosion rate and the types of corrosion that occurred in concrete iron withswamp soil medium. The methods of this study are Weight Loss method, AtomicAbsorption Spectroscopy (AAS) test, and Scanning Electron Microscope-EnergyDispersion X-Ray (SEM-EDX). This study used a different immersion timevariant, such as 20 days, 40 days, 65 days, and without medium for 65 days. Theconcrete iron used in this study is concrete U-24 or plain concrete iron 10. Thecorrosion rate that occurs in iron concrete with swamp soil medium at 20 daysimmersion is 20977.5868 mmpy, 40 days immersion is 17721.9174 mmpy, 65days immersion is 16932. 9071 and 65 days without a medium are 3023.3793mmpy. The more time, the rate of corrosion become more slowly due to theinfluence of corrosion products that have occurred. The corrosion rate without themedium is slower than the corrosion rate with the medium. The types of corrosionthat occurs in concrete iron with swamp soil medium are crevice corrosion andpitting corrosion.

Abstract

A study entitled Identification of Landslide-Prone Areas in Camba Sub-District, Maros Regency Using Microtremor has been carried out. Microtremor is ground vibration other than earthquake, it can be a vibration due to human activities and natural activities. So microtremor can occur due to vibrations due to people who are walking, car vibrations, vibrations of factory machines, wind vibrations, ocean waves or natural vibrations from the ground. This study aims to determine how much the dominant frequency produced in microtremor measurements in landslide prone areas in Camba sub-district, Maros district. Data collection was carried out by 10 points. The data obtained were processed using geopsy software. Based on the research that has been carried out, it can be concluded that the measurement point that has the biggest landslide potential is at the measurement point that has the smallest dominant frequency value with a large dominant frequency of 0.73 Hz and the measurement point that has the smallest landslide potential is at the measurement point that has a value the largest dominant frequency with a dominant frequency of 8.27 Hz. The most dominant frequency value that appears is 5 Hz.

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

This field study aims to look at the structure of rock layers and formations in the Mallawa area of Maros Regency. The method used in this studi is sampling at two points where these two points are estimated to have alignment on the layer. This method is a method of observation, direct measurement, and rock sampling at each point. From . This is obtained by several rock samples from each point which are then tested using water which serves to test the permeability and porosity of rock samples, while the hardness of the rock is tested by giving a scratch on the sample. From the research it was concluded that in general the rock structure in Pada’ Elo, Kecamatan. Mallawa, Maros Regency is composed of sedimentary rock formations.

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. Keywords: geoelectric, Wenner-Schlumberger configuration, geothermal

Abstract

This study is about Dye Sensitized Solar Cell (DSSC) which aims to determine the absorbance value of henna leaf extract (Lawsonia Inermis L) as a sensitizer in DSSC and find out how the effect of immersion time of TiO2 layer on the efficiency value produced. The method used to make the extract is maceration and to doping TiO2 using the doctor blade method with an area of 1.5x1.5 cm. In this study UV-Vis testing was carried out to determine the absorbance value of dye henna leaf extract, current and voltage testing to determine the current and voltage values obtained from cells and SEM tests to determine the surface structure of TiO2 layers. The absorbance value of the nail extract leaf extract is based on the results of the UV Vis test which is 0.077 which is located in an area with a wavelength of 663 nm. For the TiO2 coating immersion time obtained the lowest efficiency value of cells with immersion of TiO2 layer for 1 hour which is 0.0038%, then immersion of TiO2 layer for 12 hours obtained efficiency value 0.0056% and soaking TiO2 layer for 24 hours obtained efficiency value 0.0083%.
