Abstract

Electric car consists of a chassis that carries the vehicle's load, such as an electric motor to drive the wheels, and a battery as an energy source for the electric motor. Overall vehicle performance is controlled and monitored by the battery and engine controller systems. The objectives of the research on Design and Analysis of Electric Car Chassis Using the Finite Element Method Using Solidworks 2017 can be described as follows: Identifying aspects of the design strength of the AISI 4130 frame (hollow steel 40 x 60 mm). The design determines the wheel alignment of the wheel geometry, the angle of inclination of this wheel will later be used as a reference when making the frame and continues to make the geometry for the wheels and the width of the rear wheel tread. This axle uses a vehicle equivalent axle. Measurement, the rear wheel track of the vehicle axle is 1126 mm, and the front wheel track uses a track with a different width. For easier handling during maneuvers, the wheelbase is fixed at 1835.5mm, so the front front wheel track is wider than the rear wheel track. Mesh on the chassis using tetrahedral as shown in figure 2.a then loading is given to the node point position where the driver is on the chassis supporting the driver's load is 750 N and the battery is added, the weight of the BLDC motor and solar panel is 310 N and the maneuver is 100 N. The simulation results show the voltage value VonMises Stress with AISI 4130 material with a maximum stress value of 2.796 x 108 Pa, right maneuver 3.92 x 108 Pa and left maneuver 4.071 x 108 Pa with a given load of 1060 N. The maximum vonmises stress occurs when the kart maneuvers left while the highest maximum displacement occurs only due to the influence of gravity without being affected by vehicle maneuvers so that maneuvers can reduce displacement.

Abstract

The government implemented the use of a 30% biodiesel mixture in diesel fuel for all types of sectors in 2020. In the upcoming years, this policy will probably continue to be strengthened. The compatibility of the elastomers (seals, gaskets, and O-rings) used in the fuel system needs to be carefully considered, though, as biodiesel may have an adverse effect on components composed of natural rubber or synthetic rubber. This study aims to determine the compatibility of elastomeric fuel mixtures of 30% and 40% biodiesel based palm oil (CPO) in Indonesia. The elastomer used in this study, acrylonitrile butadiene rubber (NBR), is frequently utilized in the automobile industry or in fuel storage systems in the production of electricity, mining, and other industries. Using the ASTM D471 technique, the compatibility of this elastomer is evaluated based on mass swelling, swelling volume, tensile strength, and hardness. It was discovered by mass swelling, swelling volume, tensile strength, and hardness tests that the compatibility of acrylonitrile butadiene rubber diminishes with increasing biodiesel content (FAME).

Abstract

Indonesia is one of the largest essential oil producing countries in the world and is supported by natural resources with climatic conditions, soil and plant species that are very suitable for the growth of patchouli plants. The use of essential oils today is not only as a raw material for fragrances and cosmetics but also in the health sector. One of the basic ingredients for producing essential oils is patchouli. The main thing that needs to be considered in the processing of this essential patchouli oil is the yield it produces. This study aims to analyze the mass balance and yield in the processing of patchouli essential oil in a distillation system with 5kg, 4kg, 3kg patchouli leaf raw material variations. Distillation of patchouli leaves was carried out using the steam and water distillation method with a temperature in the kettle not exceeding 100 oC for 6 hours. The main variables in the processing of patchouli leaves into essential oil are distillation efficiency and the yield obtained. The more mass of patchouli leaves used, the more it will increase the distillation efficiency of 79.7%, 82.1% and 82.4% as well as the yield of the resulting oil increased 1.67%, 1.7% and 1.78%

Abstract

The goal of this research was to determine the heat resistance behavior of polymer composite fiber boards with oil palm empty fruit bunches (OPEFB) fillers as influenced by mass density and water absorption, with the hope that partition boards with OPEFB fiber fillers could reduce the heat entering the room from outside vines through directly exposed walls. The partition board under discussion is a heat insulator with a thermal conductivity test impacted by the mass density of the composite. The test method used is ASTM-C-177-2013, which consists of measuring heat propagation by modifying a 40-watt heat source and testing specimens from polymer composite partition boards formed based on standards obtained from partition forming boards with a matrix of polyester resin SHCP 2667 WNC fraction weight with a fiber weight ratio of 25 wt.%, 30 wt.%, and 35 wt.% randomly arranged (chopped strand mat/CSM). The highest thermal conductivity value was observed in a 25 wt.% fiber weight ratio of 0.141 W/m.oC at a void percentage of 7.65% for a 5 minutes test time; 0.146 W/m.oC for a 10 minutes test time; 0.151 W/m.oC for 15 minutes test time at a mass density of 1.16 gr/cm. While the 35 wt.% fiber weight ratio has the lowest thermal conductivity value of 0.137 W/m.oC at a void percentage of 4.24% for a 5 minutes test time; 0.142 W/m.oC for a 10 minutes test time; and 0.147 W/m.oC for a 15 minutes test time at a mass density of 1.24 gr/cm3 and a water absorption capacity of 3.75%. According to the investigation’s findings, the higher the water absorption capacity, the higher the thermal conductivity of the partition board, and the higher the mass density, the lower the thermal conductivity. As a result, the lower the value of the thermal conductivity of the partition board, the better the insulating properties.

Abstract

Study of power flow analysis to obtain information about the flow of power or voltage in an electric power system. As time goes by and the number of tourists on Pandang Island, especially in the development and change sector, will also increase, the amount of burden incurred will also increase, so that a good initial design is no longer suitable for the current load. For this reason, it is necessary to analyze the power flow in order to determine the condition of the electric power system. The benefits of this research are also for planning evaluation if there will be additional burden innovations. In this study, ETAP Power Station 19.0 software was used using Newton Raphson for power flow simulation. The results obtained in the Etap simulation are 37% generating load with a total active power of 10.35 KW, reactive power of 6.85 Kvar, and apparent power of 12.42 KVA. This research also increases the load by 4,800 watts, where the photovoltaic generator must increase the photovoltaic capacity from the previous 10.26 kw to 13.29 kw, therefore solar cell panels will be added as many as 8 panels.

Abstract

The use of solar panel systems as solar energy utilization has become an attractive solution in order to reduce the use of fossil energy for electricity conversion raw materials. A solar Tracker system is used to increase the efficiency of solar panels by facing the solar panels to the angle of incidence of sunlight. This research aims to design the optimum angle that will be applied to the solar tracker system at University of Singaperbangsa Karawang. This study uses the simulation method of PVsyst software to analyze the performance of solar panel systems at various variations of tilt angle and azimuth. This research involves two optimum angle variations (5° and 9°), as well as an azimuth direction of 0° (system facing North) that will be applied to a static solar panel system and a solar tracker system. The collected sunlight data was inputted from the Meteonorm 8.0 database. The results of this study inform that the solar tracker system (Tilt Angel 5°) gets the most optimal energy compared to the other three systems, with the energy produced amounting to 247.92 kWh / year, and gets the smallest percentage of lost energy which is 7.46%. Following up on this research, it is necessary to combine research methods to determine the exact position of the Tilt Angel and Azimuth, then direct application is needed to compare the accuracy of the data obtained from the simulation.

Abstract

The method of calculating the volume of fuel oil using standard 15⁰ C is one of the methods used internationally in calculating the volume of handover transactions. To standardize the calculation of fuel volume in various weather conditions, there are several fuel calculation methods, namely the Observed calculation method, th calculation method in standard 15⁰ C, the calculation method in barrels and the calculation method in long tons. For the calculation method that is suitable for use in Indonesia is the standard volume calculation method of 15⁰ C, so that in extreme weather conditions or temperature differences, the volume calculation can still be accommodated even though the difference is very significant. In this case, we take a sample calculation of the volume of MFO fuel oil through the Moto Tanker at the Belawan PLTU Jetty Port. From the measurement results, the overall volume was 4,802,983 liters of Observed, and at a standard volume of 15⁰ C, a volume of 4,747,268 liters of standard 15⁰ C was obtained. From these results, the difference between the Observed volume and the standard volume of 15⁰ C was 55,715 liters or equivalent to 1.16% of the volume Observed. So it can be concluded that the standard volume value of 15⁰ C is 1.16% smaller than the Observed volume and the standard volume of 15⁰ C will always be lower than the Observed volume. For this reason, the standard volume calculation method of 15⁰ C is a very suitable method for calculating the volume of fuel oil.
