Abstract

Lack of water is one of the problems in the agricultural sector. The location of the farm which is located above the water source causes difficulties in flowing the rice field area. During the dry season, farmers are forced to lift water using a water pump. Therefore, a more economical water pump is needed, one of that is a spiral pump which is driven by an undershot waterwheel. The results of the undershot waterwheel design obtained a diameter of 1 m, a width of 1.15 m, and a blade area of 0.459 m2. The frame of the wheel is made of plain concrete iron with a diameter of 8 mm, the blade of the wheel is made of 0.4 mm thick galvanized plate, the support for the pinwheel is made of angled iron with a size of 4 x 4 cm, while the shaft of the pinwheel is made of galvanized pipe with an outer diameter of 33.8 mm and 3.2 mm thick. From the test results, the wheel rotation is 15.2 rpm, torque is 9.5 Nm, wheel power is 15.11 watts, and the undershot waterwheel efficiency is 16.54%.

Abstract

This research focuses on manufacturing composite wings using the vacuum bag process. The vacuum bag method is used because it can reduce manufacturing time and improve the quality of the final product. This study aims to determine the impact of the vacuum bag method on the geometry between the design stages and the final results of the UAV wing. Differences in design geometry and final results are calculated by measurement. The effects of variations in thickness and loading were estimated by modeling simulations with Fusion360 Software. The geometry of the design stage and the final result did not have a significant change, with a difference of 10% in thickness, 2.45% in wing length, and 0.80% in wing width. For deformation, it can be concluded that the increase in thickness and loading is directly proportional to the magnitude of the deformation that occurs. The greater the value of thickness and loading, the greater the deformation that occurs.

Abstract

The application of natural fibers in the hybrid laminated composite with synthetic fibers potentially reduces the production cost of composite products. Jute fibers have gained interest because of their properties such as biodegradability, low cost, and high cellulose content. This study investigated the effect of chemical treatment on the woven jute fiber to determine its impact on the mechanical properties of jute/carbon hybrid composites. The chemical treatment with alkalization and then bleaching is considered for jute woven fibers before manufacturing hybrid composite. Four layers using two woven jute fibers and two woven carbon fibers were fabricated by the vacuum infusion method. Physical properties were carried out by Fourier transform infrared and x-ray diffraction to treat jute fiber. Tensile and flexural tests are carried out according to ASTM standards D638 and D790, respectively. Composite hybrid R-JKJK and P-JKJK have fulfilled the criteria to be used as an alternative helmet material.

Abstract

This study aims to determine the effect of the direction of magnetic fields and their absence on the premixed combustion of kapok oil on the flame's characteristics during the combustion process. Vegetable oils as a substitute for petroleum fuels are important for sustainable research. This research used a laboratory-scale experimental method to obtain the evolution, temperature, and flame height in premix combustion by adding magnets. Kapok oil is filled into boilers of 600 ml and heated to a temperature of 300 oC. A kapok oil vapor and air mixture is reacting in a burner chamber. Two permanent magnetic rods are placed on either side of the burner tip. This study found that the attraction of magnetic fields produces a brighter, slimmer flame with the highest temperature compared to the repulsive effect of magnetic fields without them. Lorentz force generated by magnetic fields continuously breaks off fuel's chemical chains, causing magnetic vibrations in flames. Oxygen-containing air around the burner is separating itself, causing electrons to be released, thus producing higher flame temperatures produced by rapid combustion reactions. A magnetic field around the flame induces a flow of air, which magnetically causes heat transfer around flames, resulting in varying flame heights.

Abstract

Boiling oil palm, especially in Fresh Fruit Bunches (TBS) is one of the most important stages in the palm oil processing process. During the boiling process, it is hoped the temperature and steam pressure, as well as the working time on the sterilizer, are correct so that they do not damage the quality of CPO and that the sterilizer material is also maintained and safe.. Therefore, a thermal analysis was carried out on a horizontal sterilizer using a thermodynamic analysis approach and looking for thermal efficiency at peaks I, II, and III. The research was completed using a mathematical analysis method. Data collection was carried out using literature study techniques and field observations. The results showed that the value of transient conduction on the lorry peak I: 392.476 MJ, peak II: 77.186 MJ, peak III: 28.457 MJ.

Abstract

The massive use of fossil energy will cause a buildup of CO2 gas from combustion. The Indonesian government is targeting the use of renewable energy as a solution. The renewable energy source that can be chosen is solar energy. However, the use of solar panels requires a plan so that they can operate optimally according to the conditions of the installation area. Therefore, it is necessary to study the use of solar panels on the roofs of buildings as a concrete manifestation of meeting the set targets. In this research, an analysis of electrical energy needs was carried out in Building A of the Batulicin Polytechnic (Polibali), and a simulation of the use of solar panels on the roof of Building A Polibali was conducted to obtain system specifications that could be built. The method used is a direct measurement of electricity usage data in Building A Polibali and a simulation of electrical energy that can be produced from installing solar panels using premium PVSol software. Considering the roof area, 180 solar panel modules were selected with a power rating of 285 W per module and a tilt angle of 15 degrees, so that the simulated system power was 51,3 kWp. The results obtained show that the planned production of electrical energy from solar panels can exceed the overall electricity consumption needs of Building A Polibali, which is 26,512.9 kWh per year, with production from solar panels of 75,217 kWh per year.

Abstract

Car wheels have an important role in supporting the load of the vehicle, so the wheels are required to have the strength and design that can withstand the weight of the vehicle. Good wheels must be able to withstand the weight of the vehicle as well as the collisions that occur during the use period. The collision that occurs will cause stress on the wheel material. The magnitude of the stress can be simulated using computer-aided engineering (CAE)-based software. This study simulated collisions in the case of an impact test with the SAE 175 standard, with an impact of 3200 Newton, and the wheel material used was ASTM A299, which has an elastic modulus of 200 GPa and a yield strength of 275 MPa. The wheel design has a design difference that lies in the V-shaped spokes, with the V angle for the model 1 wheel being 22°, the model 2 wheel being 50°, and the model 3 wheel being 90°. The simulation results on the values of stress and strain show that the greater the value of the V angle of the wheel, the smaller the value of the stress and strain produced due to the collisions imposed on the wheel. This is due to the better ability of the wheel design with a larger wheel V angle value to spread the stress and not accumulate at a critical point

Abstract

This study aims to carry out pneumatic trainer motion simulations using Festo Fluidsim 3.6 software programming simulation. The trainer design has three main parts, namely a frame made of iron, a programmable automatic control device in the form of a PLC, and the third is a mechanical movement device in the form of a pneumatic circuit. This tool will be integrated into a circuit system, which is then tested with three experiments based on circuit simulations made in the Festo Fluidsim 3.6 software. The test results from 3 simulation experiments show that the PLC control system can send signals to the mechanical motion of a single-acting cylinder. The PLC control system can also send signals to the mechanical motion of a double-acting cylinder with non-simultaneous motion. Other than that, the PLC control system can send signals on the mechanical motion of a double-acting cylinder with simultaneous motion. The three experimental tests found that the number of strokes for a single-acting cylinder was more than that for a double-acting cylinder. The three tests showed that they could move the cylinder well with variations in flow control, namely the flow control openings of 25, 50, 75 and 100%.

Abstract

When the battery is used, it will generate heat due to chemical processes and external factors like sunlight that make the battery hot on the solar panel-based transport e-scooter. Indirectly, the battery also receives heat from the surrounding environment. Battery temperature also affects the performance, efficiency, and performance of the battery, so to maintain battery temperature, cooling is needed. This study aims to determine the variation of battery cooling temperature on the charging power of LiFePO4 batteries on e-scooters with solar panels. This research method is carried out by making a battery-cooling device as a box with active cooling using a cooling fan to cool the battery inside. After that, it makes a management and monitoring tool for the battery cooling system to regulate and measure the temperature of the ESP32-based battery. After conducting research and data processing, it can be concluded that the advantages of installing a LifePO4 battery cooling system on an e-scooter using solar panels can increase charging power. From all the data obtained, the temperature when charging at 25oC has a power that is 19% greater than the 35oC temperature on the battery

Abstract

The use of electricity without following standards, safety, and regulations can lead to inefficiency and ongoing crises. This study aims to analyze efficiency, design strategies, and implement an Energy Management System (EMS) based on ISO 50001 at the Islamic University of Kalimantan. The methods involve literature review, observation, surveys, and primary and secondary data collection. An energy audit in three buildings on the UNISKA campus revealed an energy consumption intensity (IKE) of 16.16 kWh/m2/month, which is inefficient according to the 2012 DEPDIKNAS standards. The Gap-Analyst method was used to calculate the difference between actual and desired IKE, resulting in a difference value of 4.52 kWh/m2. With IKE savings of 11.64 kWh/m2/month, the total saved cost amounts to Rp. 81,839,250, achieving a 27.93% reduction. UNISKA management is expected to implement recommendations and the ISO 50001-based Energy Management System for energy efficiency.
