Abstract

Indonesia has the greatest potential for geothermal energy in the world. Geothermal has an important role as an alternative fuel because it is a renewable energy source, but its use has not been maximized. One of the areas that have the greatest potential for geothermal energy in South Solok, West Sumatra. Therefore, this study was conducted to determine the geothermal system in the South Solok area, West Sumatra by using the gravity method. The gravity data processing stage requires some software to get the CBA value(Complete Bouguer Anomaly), map contours of the CBA. Anomaly separation with the butterworth filter method, determination of residual anomaly slice points, and 2D modeling of geothermal systems. Based on modeling, the qualitative interpretation interprets the Complete Bouguer Anomaly map which is suspected as a geothermal prospect area is a low anomaly ranging from 7.9 mgal - 9.4 mgal which is marked in dark blue. Meanwhile, quantitative interpretation produces modeling of the AB and CD slicing with a total of four layers. This layer consists of clay rock as a cap rock, sandstone as a reservoir, granite as a heated rock as a heat source, and the last layer in the form of magma as a heat source. The anomaly modeling of these two sections is dominated by granite rock with a density value of 2500 kg/m3 for the AB section and 2550 kg/m3 for the CD section.

Abstract

The purpose of this nickel electroplating research on aluminum is to determine the effect of time on mechanical properties in the form of hardness values from specimens and then the SEM-EDX Test is carried out on specimens with the highest hardness test values to find out the microstructure and composition in the coating. The materials used in this study are nickel as the coating and aluminum 2024 as the coated material. The fixed variables used in this study include voltage (25 V), electrode distance (20 cm), water (2400 ml), salt (40gr), vinegar (1600 ml), aluminum 2024, and nickel. The free variables are variation in coating time, namely 10, 15, and 20 minutes. The results of this study showed that the highest hardness value was found in specimens with 10 minutes of immersion time with a value of 198.31 HV and the lowest in specimens with 20 minutes of immersion time with a value of 132.81 HV. After the SEM-EDX test, it was found that the micro layer structure contained pitting (defects) and the element with the highest presentation in the layer was Ni with a mass of 84.07% and an atomic number of 55.29%.

Abstract

The wear properties of metals are very important in manufacturing. This is evidenced in the many studies that analyze the wear properties of a metal. This study uses Metal Matrix Composites, where the manufacturing process uses metal as the matrix and ceramics as reinforcement with powder metallurgy manufacturing methods. Where the powder of the two composite materials is compacted and heated at a certain temperature to form a solid composite material. The purpose of this study is to ensure that the mechanical properties of the Mo/Al2O3 composite are greater than that of the constituent material. In this study, molybdenum powder was used as a matrix material and alumina as a reinforcing material. Mo has excellent mechanical properties, namely hardness and excellent wear resistance. Al2O3 has excellent wear resistance properties. Research variables include heating temperature of 900, 1000, 1100°C and holding time of heating process for 0.5, 1, 1.5 hours with compaction pressure of 125 MPa and weight fraction of Mo by 80% and Al2O3 by 10%. Based on the test results, the highest sinter density was found at a sintering temperature of 1100oC and a sintering holding time of 1.5 hours at 6.831g/cm3. The value of porosity and wear rate is getting lower, namely 28.8% and the wear rate is 0.0012 mm/minute.

Abstract

The geothermal power plant located in Gunung Salak plays a crucial role in increasing the electricity supply transmitted to the Java-Bali region, as the energy demand continues to rise. The objective of this research is to determine the 3D subsurface structure of Gunung Salak, specifically the distribution of the reservoir as the target for geothermal energy using the Gravity method. Gravity data, including gravity disturbance (gd), geoid, and Digital Elevation Model (DEM), were obtained from the ICGEM website with a total of 48740 data each. Based on the results of the residual anomaly map, the low anomalies beneath Gunung Salak have values from -5.15 to -1.88 mGal, which are suspected to be associated with the magma chamber. The high anomalies beneath the manifestations have values from 0.92 to 5.01 mGal, indicating andesitic basalt intrusive rocks believed to be the reservoir rock. Through the 3D inversion modeling of the subsurface structure of the Gunung Salak geothermal system, a clay cap with a density from 2.47 to 2.5 g/cc at depths of 0 to 700 m and andesitic basalt rock as the reservoir with a density from 2.74 to 2.91 g/cc at depths of 700 to 3000 m have been identified.

Abstract

Kebutuhan akan air oleh masyarakat semakin meningkat, sehingga penggunaan air yan berlebihan sering terjadi. Oleh karena itu perlu dibuatkan alat untuk pengendalian air PDAM agar penggunaan air dapat dilakukan lebih hemat dan efisien. Pada penelitian ini dibuatlah sistem pengendalian air PDAM dengan arduino uno yang menggunakan sensor flowmeter untuk pengukuran volume dan debit air, pompa air serta LCD untuk tampilan volume air dan debit air. Sehingga dapat diketahui dalam sehari berapa banyak liter air yang digunakan untuk kebutuhan hidup. Berdasarkan hasil pengujian, didapatkan nilai accurancy untuk volume sebesar 95.6% - 96.8 % yaitu dengan membandingkan nilai volume pembaca di arduino dan volume perhitungan manual dan  nilai accurancy untuk debit air adalah 95.6 %. Sehingga dapat dikatakan semakin tinggi nilai flowrate maka nilai error semakin kecil dan sebaliknya semakin rendah nilai flowrate maka nilai error semakin besar.

Abstract

In this research, a modification of polyurethane (PU) sponge material has been made to obtain superhydrophobic-superoleophilic properties. The PU sponge was coated with several nanomaterials such as ZnO, Fe3O4+TEOS, and stearic acid by dip-coating and drop-coating methods. The tests include selective separation of oil and water with a magnetic response. Several types of oil and organic solvents were tested for absorption capacity. The results showed that the PU@ZnO@Fe3O4@SA sponge has a good absorption capacity, from 4.37 mL to 7.37 mL. The fabricated PU sponge could selectively separate oil from water with a separation efficiency above 99%. The fabricated PU sponge also could be magnetically driven by external magnetic fields. From the characterization using 3D OM, the water contact angle was 153.38°, which indicates that the PU@ZnO@Fe3O4@SA sponge is superhydrophobic. And from surface morphology obtained an average pore size diameter of 167.475 μm.
