This study aims to 1) to know the description of student's social support 2) to understand the student's self-esteem 3) to establish the relationship between social support and student's self-esteem. The subjects of the study were the students of class VIII Determination of the sample using a total sample which means the whole population becomes the sample. The research method used is correlati…
The research has been conducted about resistivity underground modeling located at Perumnas Griya Bina Widya UNRI Tampan Subdistrict of Pekanbaru City. Resistivity underground data taken using Schlumberger geoelectrical method of electrode configuration. Geoelectric data processed with Vertical Electrical Sounding (VES). Based on the research, there were four layers in each block with different …
The aims of this study are to determine the influence of percentage of potassium hydroxide (KOH) and to the adsorption of methylene blue of the activated carbon. Activated carbon was prepared from fibers of empty fruit bunches of oil palm (fibers of EFB) pre-carbonized at 280 for 4 hours. Chemical activation was conducted to the sample for 25 hours with weight percentage of KOH of 25%, 50%, and…
The research about groundwater flow pattern in Perumnas Griya Bina Widya UNRI Tampan subdistrict of Pekanbaru have been done. Groundwater flow pattern mode from one dimension geoelectric data of Schlumberger electrode configuration. Based on formation of lithology resulted from geoelectric data, resulted four formation of lithology from block A to block G of the Perumnas. From the mapping resul…
Supercapacitor electrodes from rubber wood saw dust (RWSD) have been fabricated using experiment method with RSWD and KOH mass ratio variation of 1:1, 1:3, 1:5 and 1:17. Electrodes were carbonized at 600 oC and followed by physical activation method in CO2 gas under condition on the constant temperature of 900 oC. Chemical activation was performed using KOH solution as an activating agent. The …
A density of plasma thermal carbon ion species has been successfully simulated with the software program Matrix Laboratory (MATLAB). The code is designed from the continuity equation by time function and the Arrhenius Equation. The code is run by entering the coefficient charge each reaction and Arrhenius parameters formed as a matrix. The Arrhenius parameters are α, β, and γ. Six reaction o…
Has conducted research on the impact of particulate matter PM10 concentrations relation to the factor of temperature, humidity and wind speed have been done in August 2015 until November 2015. The methodology used in this study is the method imterprestas data. The data obtained from aerial labor kulim station Pekanbaru. Result obtained in august 2015 to november 2015, namely the concentration o…
The addition of surfactant of Sodium Dodecyl Sulfate (SDS) in activated carbon electrodes (ACE) based on from Rubber Wood SawDust (RWSD) has been analysed. The ACE synthesis was performed by combaining chemical and physical activation process. All samples were devided into four catagories such as : 0 M, 0.5 M, 1 M and 1.5 M. The physical properties density was calculated by analyzing mass, radi…
The research studied the effect of variations in chemical activation time toward adsorption rate of activated carbon from Eucalyptus Pellita wood. Eucalyptus Pellita wood used was the inside part of wood which was about 2 cm from the outer portion wood. The first process of Eucalyptus Pellita wood becoming activated carbon was done by the conventional carbonization process for 1.5 hours and con…
Flat coil inductive sensor works by detecting changes in the magnetic field of an object without a physical contact with measuring object. This study use two flat coil sensor geometry circle on Printed Circuit Board (PCB) through the etching process with indutance of Hμ5.22and Hμ9.17respectively. Flat coil evaluation sensor using LC oscillator produces the eigen frequency of 1MHz up to 2MHz. …
