Abstract

Walenrang area which has the potential for iron ore mineralization. This study aims to create a subsurface model of iron ore in Santandung Village, Walenrang area based on geomanget data. The method used is geomagnetic by identifying differences in the susceptibility of subsurface rocks. Field data acquisition is done by creating a grid. The residual magnetic anomaly map obtained is then filtered for continuation upwards of 20 m and reduction to the poles for easy interpretation. The results of the eduction to the poles obtained a magnetic value of -450 - 700 nT. The subsurface rocks of Santandung Village have a susceptibility value of 0.029 - 0.3144 SI in an area of 0.2 ha at a depth of 0 - 32 m which is identified as basalt. The iron ore formed in Santandung Village is the result of basalt mineralization.

Abstract

Research has been carried out in Benteng Village, Malangke District, NorthLuwu Regency by using the schlumberger configuration geoelectric method to determine the subsurface lithology related to the identification of groundwater depth and sea water intrusion in the area. In this study, each measurement path has a length of 150 meters. The resulting data is in the form of a resistance value and is used to find the apparent resistivity value. The data is then processed using IPI2win software to obtain lithological images of subsurface rocks. From the results of the inversion using IPI2win software, it can be seen that the depth of groundwater and sea water intrusion in the area. This can be seen from the results of the interpretation based on geological conditions and the resistivity value shows that seawater intrusion occurs on line 2, starting at a depth of 0.5-9.4 meters with a resistivity value of 1.7-5.9 Ώm. A good groundwater layer to be used as a borehole is on line 1, starting from a depth of 1. 1-22.01 meters with a resistivity value ranging from 53.2-160.5 Ώm, because on line 1 sea water intrusion is not found.

Abstract

A research has been carried out with the title Spatial Analysis of the Potential Distribution of Rocks in the Hot Springs Area which aims to determine the potential distribution of rocks in the Pincara hot spring area and to determine the subsurface rock structure of the Pincara hot spring area based on the potential properties of the rocks. This study uses a Self Potential (SP) tool, by measuring the potential value at each measurement point, the potential value of surface temperature and the pH of hot water as supporting data. Retrieval of data for each measurement point using a fixed base technique (fix base). Potential data collection for daily correction is done by measuring the potential value at the same point repeatedly in a certain time interval. SP data collection points are 50 with a grid spacing of 5 meters. The results of the research in map 1 show that the characteristics of Pincara 1 hot springs have a surface temperature of 650C, smell of sulfur, there are boasting of gas bubbles, a measured pH of 7, while in map 2 the measured surface temperature of hot springs is 690C, clear, steamy, smelly. sulfur, visible boasting of gas bubbles, measured pH 8. The highest self potential value is 69.2 mV, the lowest self potential data is 1.2 mV. The average selfpotential in the study area has a value of 17.245 mV. This indicates the presence of igneous rock that causes anomaly. Igneous rock is rock that is conductive.

Abstract

A research has been conducted on the processing of peat water into clean water. This processing aims to reduce the metal content in the peat water content. Before treatment, peat water had high levels of iron, manganese and lead of 0.09 Mg / l, 2.76 Mg / l, and 0.17 Mg / l. The metal parameter still exceeds the maximum limit set by PERMENKES RI NO.416 / Menkes / Per / IX / 1990. The processing methodology used is neutralization, aeration and filterization. Neutralization process. The results showed that the manganese and iron parameters decreased, namely manganese from 2.75 Mg / l to 0.5 Mg / l, iron from 0.09 Mg / l to 0.05 Mg / l. Meanwhile, the lead content still has levels that exceed the maximum reference limit, this is due to the use of pipes containing lead elements

Abstract

Vibration is the movement of an object back and forth or oscillations that occur periodically. A construction that has mass and elasticity will basically experience vibration, so it must pay attention to the oscillatory nature of the vibration. Excessive vibration will cause a malfunction in the construction, so a model is needed to determine the vibration characteristics of the construction. One of the vibration phenomena is the movement of the spring. To create a spring motion graph using the Euler method, software such as the scilab application is needed. SCILAB is a software for numerical computing that is open source and can be run on Linux, Windows and MacOS operating systems.

Abstract

A research has been carried out with the title Spatial Analysis of the Distribution of Rock Self Potential in the Hot Springs Area which aims to determine the potential distribution of rocks in the Pincara hot spring area and to determine the subsurface rock structure of the Pincara hot spring area based on the potential properties of the rock. This study uses a Self Potential (SP) tool, by measuring the potential value at each measurement point, the potential value of the surface temperature and pH of hot water as supporting data. Data collection for each measurement point uses a fixed base technique, namely by positioning one fixed electrode as a reference point, while the other electrode moves from one measuring point to another. Potential data retrieval for daily correction is done by measuring the potential value at the same point repeatedly in a certain time interval. The SP data collection points are 50 with a grid spacing of 5 meters. The results on map 1 show that the characteristics of Pincara hot springs 1 have a surface temperature of 65oC, smell of sulfur, there are gas bubbles, pH is 7, while in map 2 the surface temperature of hot springs is 69oC, clear, steamy, smells sulfur, gas bubbles can be seen, the measured pH is 8. The highest self-potential value is 69.2 mV, the lowest self-potential data is 1.2 mV. The average self-potential in the study area has a value of 17,245 mV. The research area is the conductive zone. This is indicated by the low value of the self-measured potential, which is numerically positive in the tens order. The lowest potential anomaly zone was found in the northern area of the study area with a self-potential value of 1.2 mV. The self-potential value is on the order of tens of millivolts. This indicates the presence of igneous rocks that cause the anomaly. Igneous rock is a conductive rock.

Abstract

PID control is a control that will react to the error that has been given by the sensor, so that it can provide an improvement value to the output value. The RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L) and a capacitor (C), which are arranged in series or parallel. The resistance produced by the resistor is referred to as resistance, the resistance produced by the inductor is usually called the inductive reactance symbolized by XL, while the resistance generated by the capacitor is called the capacitive reactance symbolized by XC. The method of solving an electric circuit can be solved by using the Laplace transform associated with using SCILAB software. SCILAB is open source software and can be run on Windows, Mac and Linux operating systems.
