Abstract

This study aims to predict corrosion in water distribution pipes at the Bukit Indah Unimal campus. Corrosion is the damage to chemical elements in a metal that changes the original properties of the metal. There are four kinds of processes for corrosion, namely, one anode loses electrons, two cathodes accept electrons, three liquids and four metals connect the cathode and anode. The geoelectric resistivity method is used to determine the soil resistance properties of the subsurface layer. The wenner 4 pin method is a geoelectric data retrieval that is often used with the same pin spacing arrangement. Res2Dinv is software that is on a computer to generate 2-dimensional images from the resistivity data obtained and determine the layer below the surface. From the inverse results, the smallest error value can be obtained when iterating up to 4 times, namely Java Road 45.3%, Sulawesi Road 49.6%, Kalimantan Road 30.6%, Sumatra II Road 46.1%, Main Gate 41.1% Sumatra I 23.4%. Based on the data, the measurable results below the surface range from 0.05 m to 5 m.

Abstract

Heat exchanger expected to high effectiveness of heat transfer. Type of plate heat exchanger was more efficient compare to another heat exchangers in industrial applications with pressure less than 30 bar. The increased velocity of cold fluid flow has an impact to increase the performance of heat exchanger by  heat transfer rate (Q), heat transfer coefficient (U), and the effectiveness of heat exchanger (ε). The increased velocity of cold fluid flow also incresing the heat transfer rate. The study carried out by variation of the cold fluid velocity at 0.03 m/s, 0.037 m/s, 0.045 m/s, 0.051 m/s and 0.059 m/s. Inlet hot fluid temperature (Th,i) at 45°C and cold fluid temperature (Tc,i) at 27°C constant. The results shows Q value from the original 1570.71 Watt to 1916.16 Watt on the hot side and 1751.89 Watt to 2187.01 Watt on the cold side. The U value from the original 1180.46 W/m2.°C becomes 1408,75 W/m2. °C. The ε value increased from 60.33% to 75.69%. The increasing of  cold fluid velocity directly proportional to the the heat transfer rate (Q) and performance of the plate heat exchanger. This Phenomenon due to the faster circulation of the cold fluid, which causes the cold fluid to quickly return to its initial temperature (Th,i), an than increasing the plate heat exchanger's performance.

Abstract

Voltammetry is widely used to detect heavy metals such as mercury (Hg). The sensor material influences the results of the voltammetry method. Carbon-based sensors are commonly developed because of their wide potential range, low background current, inexpensive, inert, and suitable for various sensors. Recently, Tire Waste (TW) was chosen as a carbon source for the manufacture of electrodes because it is rich in carbon (88%). The material is easy to obtain, green technology and a carbon source that has not been properly utilized. Separation of carbon material from TW using the pyrolysis method produces 4.32 gr (2.6%) of soot (from 200 gr TW) as a material for making carbon-based Hg sensors. The XRD pattern of TW soot has amorphous phases. SEM topography shows that the surface of TW soot consists of particles that are almost uniform in shape. The estimated particle size is about 0.25 µm. The sensor was made with a mixture of TW soot and paraffin with a 2:1 ratio. Testing the specific value of sensor capacitance using the Cyclic Voltammetry (CV) method showed the presence of cathodic and anodic currents. The Hg deposit occurred at a peak cathodic current at a scan rate of 20 mV/s. The Limit of Detection (LoD) value is 0.0681 ppm and the Limit of Quantitation (LoQ) is 0.229 ppm. Measurement of Hg in natural water samples used river water from the Aceh Jaya sub-district at two points representing the upstream and downstream of the river. The Hg concentrations obtained were 0.000536 ppm and 0.00182 ppm, respectively and were compared with the inspection results using Atomic Absorbance Spectroscopy (AAS), 0.00058 ppm and 0.00186 ppm, respectively. The t-test results of the two Hg measurement methods at a significance level (α) of 5% obtained tcount > ttable (0.0208 <2.306), indicating that there is a significant difference between the two Hg concentration measurement methods for natural water.

Abstract

Styrofoam as food packaging has a bad impact on the environment and the human body because it is made of benzene compounds. The purpose of this research is to look for environmentally friendly and safe food packaging alternatives in the form of biofoam made from waste rice plants and tapioca flour as natural adhesives. The biofoam fabrication process as food packaging is done by mixing straw waste that has been mashed with tapioca solution until it is homogeneous and has a higher viscosity, and then printing using a tool. Thermopress uses a pressure of 9,801 MPa (100 kg) with a temperature of 120°C for 14 minutes of pressing. The variations used are the use of mesh 40, 60, and 80 for the level of roughness of rice straw that has been treated in a crusher. The results of Biofoam testing with the three mesh variations 40, 60, and 80 can decompose inside soil for 28 days, and the results of testing with a mesh of 40 found low water absorption resistance with a weight gain of 36%, and the heat resistance test experienced a weight gain of 1.681%, meanwhile, biofoam with a mesh of 60 has added weight after testing water absorption of 23%, and the heat resistance test has a weight gain of 1%. And on biofoam with mesh 80, there was a weight gain after testing water absorption of 15% and resistance to heat with an increase in weight of 1%.

Abstract

The transition of energy sources from fossil fuel to biofuel is becoming a major topic in the world towards renewable energy to reduce greenhouse gas emissions, improve environmental air quality, and reduce dependence on fossil fuel in the future. This study aims to evaluate the effect of increasing the concentration of oxygenated biofuel in diesel fuel on the emissions of diesel engines. In this study, B30 (30% biodiesel and 70% diesel) was used as a base fuel, and a fraction of pure biodiesel (B100) was added to increase the biodiesel concentration in B30 fuel to create B40 (40% biodiesel and 60% diesel). Furthermore, the addition of 5% and 10% of bioethanol as a fuel additive in the fuel blend was conducted while maintaining a biodiesel concentration of 40%. The effect of bioethanol contained in the fuel blends was tested using a single-cylinder 418 cc diesel engine.  The experiment was carried out at an engine speed of 1000–3000 rpm. The result shows that the concentration of the diesel-biodiesel-bioethanol blend affected the emissions produced by the diesel engines. Combustion efficiency increased with the concentration of biodiesel in the diesel fuel, as shown by reduced CO emissions, increased CO2 emissions, and increased NOx emissions at engine speeds of 2000–3000 rpm. In comparison to 5% bioethanol at various engine speeds, adding 10% bioethanol has a disadvantageous effect on the combustion process, increasing CO and HC emissions.

Abstract

Honeycomb is applied to the Open Series Subsonic Wind Tunnel which aims to obtain a unidirectional fluid flow shape with uniform (laminar) and stable fluid flow velocities. Honeycomb testing was carried out experimentally at a flow velocity of 3 m / s without honeycomb using a variety of shapes: hexagonal, square, and circular. Each honeycomb shaped to 8mm diameter. The results of the analysis on honeycomb testing with variations in shape obtained the value of turbulence intensity that occurs in the test section, namely for hexagonal shape variations the flow that occurs is better than circular shape, while in circular shape variations the value of turbulence intensity is better than square shape. The results of the Reynold's number calculation show that the flow that occurs is laminar with the following values, in the hexagonal shape variation the value is 787, circular shape 956.48, and square shape 1199.42. After calculating the turbulence intensity and Reynold's number, we can conclude that honeycomb with hexagonal shape variation is optimal than circular shape, and circular is optimal than square.
