Energy is one of the basic needs in the human life cycle. Energy sources that are often used are non-recyclable energy sources, so a new innovation is needed in overcoming the energy crisis problem by using renewable natural materials, one of which is efforts to make energy storage components made from activated carbon.Activated carbon is a type of carbon that has a large surface area. Activated carbon can be applied as an activated carbon electrode such as lithium ion batteries and supercapacitor. Electrode in this study were produced from sugar palm midrib biomass. The electrodes production utilized chemical activation using Kalium Hydroxyde with various percentage of 5%, 10%, and 15% which of PA-05, PA-10, and PA-15 recpectively. Aktivated carbon electrodes were prepared through a pre-carbonization, chemical activation, carbonization process using N 2 gas at temperature 600 °C and followed by physical activation using CO 2 gas at temperature 900 °C. Analysis using XRD for microstructure show semicrystalline structure for the activated carbon electrodes which is by the presence of peaks at angel of 2θ around 24° and 44° with respectively crystal orientation (002) and (100).

The need for water daily is a big problem for people living around Muara Fajar Final Processing Place (TPA) – Rumbai. This study aims to identify the depth of subsurface structures around the Muara Fajar landfill area using the Schlumberger configuration dielectric method and determine the water quality in the community wells around the landfill site. The data obtained in the acquisition process are used to calculate the apparent resistivity value at each measurement point and analyzed quantitatively and qualitatively. Then proceed with the inversion process using the progress program so that obtained resistivity value and layer thickness at each point of measurement. The results of measurement inline 1 get a range of resistivity values ranging from 961.19 – 2.10 Ωm and line 2 of 109.31 – 31.15 Ωm. Underground water taken is residents well water in the research area as many as 5 sample points using GPS. This underground water sample will be tested with parameters such as pH, TDS, Conductivity, Salinity, and Turbidity. Underground water cannot be consumed from the results of the water quality test with the parameters mentioned at the beginning if referring to the Regulation of the Minister of Health of the Republic of Indonesia because the pH obtained in all underground water samples is < 6.5 or acidic, the value of the conductivity exceeds the quality standard, and high dominant salinity value. As for the TDS and Turbidity parameters, the values are by the quality standard.

The electrical energy crisis occurs due to the availability of non-renewable sources of electrical energy. The focus of research is currently developing on how to store electrical energy using biomass energy. This study aims to analyze the electrochemical properties of the palm frond based carbon electrode using electrolyte solution of Na 2 SO 4 . Pre-carbonization of palm fronds was carried out using an electric oven with a temperature of 100 °C – 250 °C for 2 hours. Chemical activation using KOH activating agent with a concentration of 0.3 M at 80 °C for 2 hours. Carbonization was carried out at a temperature of 600 °C using an N 2 gas environment and followed by a chemical activation process using CO 2 gas at a temperature of 850 °C for 2.5 hours. Na 2 SO 4 with a concentration of 0.5 M is used as a solution in the manufacture of supercapacitor cells. The scanning rate is inversely proportional to the specific capacitance value generated. Characterization of electrochemical properties was carried out using the cyclic voltammetry method resulting in a specific capacitance value of 61.71 F/g for a scan rate of 1 mV/s, 57.93 F/g for scan rate of 2 mV/s and 51.37 F/g for scan  rate of 5 mV/s.

Magnetic properties and morphology of natural sand has been carried out in Logas Village, Kuantan Singingi Regency have been determined. Iron sand samples were processed using iron sand separator (ISS) prior to ball milling for separating between magnetic and non magnetic particles. The product of ISS was milled for 90 hours using ball milling first step method with milling ball size of 1.5 cm. Themagnetic and non-magnetic particles of ball milling products were separated  using Neodymium Iron Boron (NdFeB) magnet. The product of ball milling first step then was milled for another 30 hours with milling ball size of 0.5 cm and 0.7 cm. The susceptibility and mass susceptibility were determined based on magnetic induction of a selenoid measured using Probe Magnetic Pasco PS-2162. The composition of Logas natural sand was measured using x-ray fluorescence spectroscopy (XRF). The morphology of the magnetic particles are determined using scanning electron microscope (SEM). The results showed that the particle size of natural sand for 90 hours + 30 hours milling displays the particle sizes from 100 µm to 800 µm. As for the particle size of the samples synthesized with 90 hours + 30 hours for 0.7 cm milling ball size, the particles are almost evenly distributed, which is about 5 µm to 100 µm. The content of Fe and Ti in the sample has increased while for Si has decreased. Mass susceptibility increases with increasing ball milling time and ball milling size.
对关丹Singingi县Logas村天然砂的磁性和形貌进行了测定。铁砂样品在球磨前先用铁砂分选机进行磁性和非磁性颗粒的分离。采用球磨第一步法,磨球尺寸为1.5 cm,对ISS产品进行90小时的研磨。采用钕铁硼磁铁对球磨产品的磁性和非磁性颗粒进行分离。第一步球磨后的产品再进行30小时的球磨,球磨尺寸分别为0.5 cm和0.7 cm。利用Probe magnetic Pasco PS-2162测定的类硒化合物的磁感应强度测定了其磁化率和质量磁化率。采用x射线荧光光谱法(XRF)测定了Logas天然砂的成分。用扫描电子显微镜(SEM)测定了磁性颗粒的形貌。结果表明:天然砂经过90 h + 30 h磨矿后的粒径范围为100 ~ 800µm;对于0.7 cm磨球粒度,90小时+ 30小时合成的样品粒度,颗粒分布基本均匀,约为5µm ~ 100µm。样品中Fe和Ti的含量有所增加,而Si的含量有所下降。随着球磨时间和球磨粒度的增加,质量磁化率增大。

This research has been worked in the Graha Mustamindo Permai 3 Housing area, Rimba Panjang Village, Tambang District. This research been thorough to calculate the value of measured rock resistivity in Graha Mustamindo Permai 3 Housing and analyze rock layer types through rock resistivity values at Sepakat street, Rimba Panjang, Riau. The method using in this research is geoelectric resistivity of the Dipole-dipole configuration, two lanes with the same length of 100 meters are used and spacing between electrodes is 7 meters. The data obtained were processed using Res2Dinv software version 3.54.44. The data result that obtained show two differences trajectories in Rimba Panjang Village has varying resistivity, namely in the first lane around 1.595 Ωm to 2,762 Ωm and in the second lane 1.594 Ωm to 5,879 Ωm. Groundwater potential in the first and second lanes is quite large and is thought to be in a free aquifer so that it is easy to drill.
