Abstract

The Air Conditioning (AC) system is an important requirement for vehicle passengers to get thermal comfort. However, the AC system draws power from the engine to drive the compressor. Meanwhile, vehicles driven by Liquefied Petroleum Gas (LPG) provide decent cooling potential to assist the main air conditioning system. Therefore, this study aims to examine the effect of cooling on LPG-fueled vehicles by utilizing LPG flow to be used as a secondary refrigerant. The research was carried out on a 1495 cc engine with a special evaporator which was tested at variations of blower speed 1, 2, and 3. The tests were carried out at engine speeds of 1000, 2000, and 3000 rpm. The results showed the lowest cooling effect at blower speed level 1 with engine speed of 1000 rpm and the highest at blower speed level 3 with engine speed of 3000 rpm. The greatest cooling effect is obtained at 373 Watts at 3000 rpm engine speed and level 3 blower speed.

Abstract

Patents have an important role in increasing the competitiveness of a nation. Patents encourage researchers and inventors to develop new ideas, which allows them to obtain exclusive rights to their inventions. However, many researchers have produced outputs in the form of prototypes, processes, and key methods for making tools or products, but some of them have not registered legal protection for their findings in the form of patents because they are not competent to draft patent documents. Therefore, this technical note presents practical steps in preparing patent documents, especially for novice researchers. This technical note is limited to patents in the mechanical field. The examples provided are also only an alternative and not the only way to prepare patent documents. We hope that this technical note will benefit novice researchers and encourage them to register patents for their research findings.

Abstract

The emergence of Corona Virus Disease 19 (Covid-19) required a new method to control its spread. During this time, controlling COVID-19 was carried out by implementation of a sterilization chamber using a liquid-based disinfectant. However, the use of liquid-based disinfectants has been evaluated to be less effective because it allows disrupting the respiratory tract. Therefore, this work presents a negative pressure sterilization chamber using Ozone and UV-C lamp. Ozone has been recommended by the Indonesian Institute of Sciences (LIPI) as a substitute for liquid-based disinfectants. In addition, to maximize performance, the chambers are added with UV-C lamps. The negative pressure sterilization chamber with Ozone and ultraviolet lamps was successfully created with the main parts of the cubicle chamber, an Ozone generator, at least one ultraviolet lamp, exhaust fan, switch, and a timer. The negative pressure sterilization chamber with Ozone and ultraviolet lamps according to this work, where the Ozone supply from the Ozone generator is made automatically to the door opening and closing. The duration of the Ozone supply was regulated by a timer. Then, the ultraviolet lamp can be activated together with Ozone or independently. With the implementation of this sterilization chamber, the spread of the Covid-19 virus is expected to be suppressed in a safer way than using liquid-based disinfectants.

Abstract

The demand for energy is increasing due to population growth, technological advancements, and a growing need for sustainable energy sources. Indonesia, which faces an energy deficit, is exploring alternatives to fossil fuels. Biogas, produced through the anaerobic fermentation of organic matter, offers a clean and sustainable energy option while addressing waste disposal issues. Therefore, this literature review examines various aspects of a biogas power plant, including a feasibility study that encompasses technical and economic analyses, generator design, trials, implementation, and post-implementation evaluation. In this review, we gathered scientific papers from Google Scholar using the keywords "pembangkit listrik biogas" between 2019 and 2022, with a focus on recent content. Patents and citations were excluded from the Google Scholar searches to ensure article relevance. Out of a total of 40 articles, 30 were rejected because they did not originate from scientific journals. The collected articles are categorized based on the materials used for biogas generation in power plants. This systematic approach yielded 10 relevant articles. Consequently, the literature reveals that various raw materials, such as palm oil mill waste (POME), livestock manure, and organic waste, hold the potential for biogas production. The results emphasize the economic feasibility of specific biogas projects, the environmental challenges they pose, and the positive impact they have on community well-being

Abstract

In this work, naturally available moringa oleifera leaves (also known as horseradish trees or drumstick trees) are chosen as a heterogeneous catalyst in the transesterification for biodiesel production from palm oil. The dry moringa oleifera leaves are calcinated at 700 °C for 3 hours to improve their adsorbing property. The calcinated catalyst characterization analysis from XRD and EDX highlights the presence of calcium, potassium, and other elements. Response surface method (RSM) optimization and artificial neural network (ANN) modeling were carried out to elucidate the interaction effect of significant process variables on biodiesel yield. The results show that a maximum biodiesel yield of 92.82% was achieved at optimum conditions of catalyst usage (9 wt.%), molar ratio, methanol to triglyceride (7:1), temperature (50 °C) and reaction time (120 min). The catalyst usage (wt.%) was identified as a significant process variable, followed by the molar ratio. Furthermore, the biodiesel’s significant fuel properties in terms of thermal, physical, chemical, and elemental match the established standards of ASTM. Finally, when the catalyst was reused for five cycles, more than 50% of the biodiesel yield was achieved.

Abstract

In 2022, the World Liquified Petroleum Gas Association (WLPGA) reported that there are more than 28.3 million LPG-fueled vehicles used throughout the world with an increasing trend in the last 20 years. The growth of LPG-fueled vehicles will require more mechanics from vocational school graduates who master environmentally friendly technology. Considering the availability of resources, Muhammadiyah Vocational High School 1 Bandongan Magelang (SMK MUTU Bandongan) has the potential to complement the competencies of graduates with mastery and skills in servicing modern and environmentally friendly vehicles, as one of their uniqueness from others. Therefore, we develop and implement environmentally friendly automotive technology learning media, especially LPG-fueled vehicles at SMK MUTU Bandongan. This is an implementation of research on LPG-fueled vehicles over the last 10 years. Activities are carried out through (1) rebuilding and reconditioning the engine which will be modified into a bi-fuel engine; (2) procurement and installation of converter kits; and (3) increasing teacher competency.

Abstract

The current study proposed an innovative combined power and cooling solar Organic Rankine Cycle (ORC) with bottoming vapour absorption (VAS) and vapour compression refrigeration (VCP) cycles using ammonia–water as the working fluid. The advantage of these cycles is the integration of two cooling evaporators, producing equivalent refrigerating effects from the VCP condensate. The power generation sub-system, the topping cycle, employed a solar-driven ORC. At operating conditions, the energy and exergy efficiencies stood at 38.63 and 42.09%, respectively, with overall refrigerating effect, power output, and COP calculated at 1358 kW, 26.65 kW, and 2.34 in that order. The parametric results indicated a 40% and 55% increase in energy and exergy efficiencies at high turbine inlet temperatures, with a 1.73 % increase in refrigerating effect and a 1.56% decrease in the exergy of cooling. Similarly, at an elevated generator pressure of 4.75 bar, an overall COP of 3.046 was reached. The total exergy of products and fuel was calculated at 1347.91 and 786.38 kW, respectively, with an exergy destruction ratio of 0.997. The results showed a total improvement potential (IP) of 426.768 kW, with the evaporators, absorber, and heat exchanger having the highest IP of 66. 32, 119.4, and 68.08 kW respectively. The study showed enhancement in performance when compared with previous studies and recommended system optimization and sustainability analysis as future considerations for system practical application.
