Abstract

The impact of the converter kit type on the performance of diesel engines using biodiesel and LPG fuel has been explored. Converter kits play a vital role in transforming the fuel supply system, and experiments have been conducted to assess their influence on various engine performance parameters. The findings of the study indicate that the selection of a converter kit significantly affects the performance of dual-fuel diesel engines (biodiesel and LPG). Gas Heater converter kits, including type 1, type 2, and type 3 variations, were scrutinized in this research. Testing revealed variations in LPG-Biodiesel fuel mixing ratios depending on the type of converter kit employed. For instance, Gas Heater type 3 achieves the highest value with a mixing ratio of 14.4. Furthermore, the performance of the engine in terms of power and torque is also impacted by the type of converter kit utilized. Gas Heater type 1 exhibits peak performance, with power reaching 5.4 kW and torque measuring 34.81 Nm. Despite the operational costs of dual-fuel diesel engines tending to be higher than those using pure biodiesel, the research concludes that the choice of the converter kit type can have a substantial effect on engine performance, particularly regarding fuel efficiency.

Abstract

Water is a natural resource that is very important for life in the world, especially for humans and other living things. There are few areas in Indonesia that have unsuitable water due to water pollution and limited fresh water source. Distillation is an effective way to produce clean water that is free from impurities in the form of small solids, germs and bacteria. One type of distillation systems is a solar distillation. However, the use of these still has low productivity. There are several ways to increase the productivity of solar distillation systems, one of them is by adding thermal energy storage material such as aluminum oxide (Al2O3) nanoparticles. This study based on  experimental method by comparing a solar distillation systems with the addition of Al2O3 nanoparticles on the absorber plate coating to the coating without the addition of Al2O3. The test results showed that the addition of Al2O3 nanoparticles increased the productivity of solar distillation. The results show the addition of mass concentration of Al2O3 (nano particles): 10%; 15% and 20% ,  increased distillate  production by: 44.73%; 88.98% and 134.85% compared without the addition of nanoparticles to the absorber plate coating.

Abstract

Turbines are one important component in a power plant. The function of the turbine is to utilize the potential energy contained in the steam which is then converted into kinetic energy by the nozzle, then the kinetic energy is converted again into mechanical energy in the turbine blade and shaft rotation. In a rankine cycle after the steam comes out of the Low Pressure Turbine (LPT), the steam will change in phase from gas to liquid by passing through the condenser. The condensate water is heated again through a Low Pressure Heater (LPH) until finally it is heated again to the High Pressure Heater (HPH) before entering the boiler. But whether the performance of the turbine if when the HPH is not operating will decrease. In this study, an efficiency calculation will be carried out between the condition of the HPH operating and the condition of the HPH not operating, as well as finding coal consumption in both conditions. Based on the study, turbine efficiency did not show any significant difference between the condition of the HPH being in operation and the HPH not operating, that is 94.07% for the condition of the HPH to operate and 93.72% for the condition of the HPH not operating. While coal consumption at the time the HPH was operating was 164 Ton / h and at the HPH not operating was 170 Ton /h.

Abstract

Maintenance on the turbine must always be carried out, because if one component of the turbine engine is damaged, it will affect the entire performance of the turbine engine. The function of bearing lubrication in turbines is to prevent direct contact between the bearing and the turbine shaft. Therefore, lubrication is needed. Bearing lubrication on the turbine is a very important issue so that the turbine should not be rotated without lubrication will cause material damage. Preventive maintenance of turbines can be pursued by implementing QCC PM. Adding a portable purifier when excessive water content occurs, adjusting the pressure steam seal serves to prevent main steam from entering the bearing area which can cause high water content due to mixing of oil with water. Making a steam block serves to prevent steam from entering the bearing area lubricated by VG 46 medium oil, causing high water content. And routine maintenance to check the mesh aims to assess the feasibility of the mesh and the suitability of the needs of the cleanliness purifier oil system which can be seen from the CBM data, namely tribology monitoring.

Abstract

Distillation is a water purification process through evaporation and condensation. Research on solar distillation was developed using the Computational Fluid Dynamic (CFD) method to obtain an overview of the transmission of solar radiation heat by the cover glass for variations in the angle of the glass inclination of 100, 200 and 300. The water height in the basin is 100 mm. The simulation results show that the heating process with variations in the angle of the cover glass affects the distillation results. The smaller angle of the cover glass inclination, the higher heat flux entering the basin so that the evaporation process becomes higher which ultimately increases the amount of distillate water production produced. The highest heat flux entering the distillation system was achieved by the system with a cover glass inclination angle of 100 with a value of 388.525 W / m2, while the lowest was at an angle of 300 with a value of 379.792 W / m2. In addition, the highest distillate production was obtained on the cover glass with an inclination angle of 10 ° of 1.078 cc. For operational hours at 13.00 WIB and simulation time 180 seconds.
