Abstract

This research aims to determine the influence of variations of coconut shell charcoal and bamboo charcoal on briquette characteristics, thus obtained optimum composition that produces briquette with the best characteristic. This research is a laboratory experimentation study, with free variables being charcoal compositions, and bound variables are characteristic briquettes consisting of: Heat value, moisture content, and ignition length. The results showed that variations in the composition of briquette from coconut charcoal and bamboo charcoal influenced briquette characteristics, moisture value, moisture content, and the length of time of ignition. The highest heat value is obtained on the composition of 10% of bamboo charcoal and 90% of coconut shell Charcoal is 7110.73 cal/G with a water content of 4.82% and the length of time of 150.45 minutes.

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 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

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%.

Abstract

Leaf spring is one of a component of the vehicle which are used to vibration damping caused by the force. Some cases that occur in the vehicle namely overload. This case can affect to fatigue life of steel leaf spring. One of a method that use to fatigue life prediction is high fatigue cycle where this method can be simulated using the finite element method. The number both element and node used in this research where 6961 element and 14726 nodes, respectively. Magnitude of the force used is 80 KN, 100 KN, and 200 KN where thus force are used to prediction of the fatigue life steel leaf spring. The result of this research revealed force 80 KN have the fatigue life longer than force 200 KN and 200 KN which is 106 cycle. In addition, the critical value of the fatigue life 80 KN is smaller than 100 KN, and 200 KN. As such as, the force 80 KN is recommendation as allowed force which use to vehicle. This value is validated by safety factor analysis where the force allowed as 80 KN with safety factor equal to 2.56.

Abstract

This study was to determine the effect of storage time on temperature, humidity and freshness of vegetables on different packages. This research was carried out by packing green mustard vegetables, fruit tomatoes, and potato fruit using banana leaves and charcoal and without packaging using a thermohygrometer to measure temperature and humidity. Data retrieval is done once a day at 09.00 WITA to complete. The results of this study indicate that there is an effect of storage time on the value of temperature, humidity and freshness of vegetables. The freshness of green mustard vegetables lasts longer with banana leaf packaging than those using charcoal and without packaging. Freshness for fruit tomatoes and curly tomatoes lasts longer on the packaging of banana leaves that use charcoal than without packaging and which use banana leaf packaging. old without packaging compared to packaging and charcoal.

Abstract

This research aims to determine the seepage of liquid waste in Makassar industry area or well known as KIMA. The method used is a geoelectric resistivity wenner configuration on five lines within 150 m and 75 m. From those five lines that has been measured revealed that there is seepage of a waste. It is signed with the resistivity comes to low it is <10Ω.m. The waste seepage is found at a distance of 15 m which is the closest distance from the waste source whereas the waste seepage farthest from the source of waste is found at a distance of 155 m and the waste seepage found from interpretation result uneven on each line.
