Abstract

Water has become a vital necessity for every living organism to survive, leading to a threefold increase in global freshwater usage over the past 50 years. However, only 2.8% of the Earth's surface water is freshwater, while the rest is seawater. Therefore, seawater is processed into clean freshwater through desalination methods to make it consumable for the public. The desalination process involves two stages: evaporation and condensation aided by heat energy from a heater plate and a vacuum system. The use of vacuum in the desalination device aims to accelerate evaporation. In this study, three vacuum pressure variables were tested, namely no vacuum, 1 inHg vacuum pressure, and 2 inHg vacuum pressure. Data will be collected every 5 minutes for a total duration of 30 minutes for each variable. The research findings indicate that desalination using a vacuum system significantly affects the evaporation rate and the amount of freshwater obtained from the condensation process.

Abstract

Clean and sustainable energy sources are needed to meet global energy demand. Geothermal Power Plants (GPPs) may generate power from Earth's heat. However, GPPs release hazardous hydrogen sulfide (H2S) gas. To overcome this problem and maximize on resource potential, researchers have investigated converting GPP-emitted H2S into hydrogen (H2). The Fe-Cl hybrid indirect electrolysis technique is used to analyze the thermodynamics of hydrogen synthesis from H2S in GPPs. Electrolysis electricity, hydrogen generation rate, and electrolyzer energy and exergy efficiency are examined in the thermodynamic analysis. The foundation parameters show that the electrolysis process uses 20.57 kWh of power every kilogram of H2 generated. Energy and exergy efficiencies of the electrolyzer are 89.89% and 97.72%, respectively, exhibiting system efficiency. The research also examines how H2S mass flow rate and electrolysis temperature affect energy efficiency, exergy efficiency, and power consumption. Optimizing hydrogen generation and system performance requires these elements. This study analyzes the thermodynamics of hydrogen synthesis from H2S in GPPs to create sustainable and ecologically friendly energy options. H2S emissions from GPPs might be used to efficiently produce hydrogen as a renewable energy source with more research.

Abstract

This article features experimental findings on the tensile testing procedure conducted on package seals made from Polyethylene Terephthalate (PET)-Low-Density Polyethylene (LDPE)-Aluminum Foil composite materials commonly employed in food packaging applications. This study aims to ascertain the outcomes of the tensile test or tensile strength of the packaging seal utilizing the Auto Tensile Tester XLW according to the ASTM F88 standards. The tensile test involves using two types of variables: independent variables and dependent variables. The study used temperature (°C) and holding time (s) as independent factors, whereas the dependent variable is the tensile test results or tensile strength (N/mm2). This study utilized identical parameters for each variable. The specimen's measurements were 15mm x 25mm. This experiment included three temperature factors and a constant holding time of 1 second. Every parameter underwent four tests, resulting in twelve test samples. Based on the findings, the optimal temperature range for achieving the most efficient packing sealing was 135oC. The maximum sealing strength of 17.50 N/mm2 was attained within this temperature range, and the outcomes were influenced by both the temperature and the duration of the holding period. Each sample has distinct values, encompassing a rather narrow range.

Abstract

The energy crisis is increasingly felt starting from the scarcity of petroleum and gas fuels plus the increasingly expensive price makes it necessary to make efforts to obtain alternative renewable energy. One of the biomass materials that can be used as briquettes is hazelnut shells because in some observations in the field hazelnut shells tend to be discarded after taking the meat. The purpose of this study was to determine the differences in the characteristics of briquettes produced such as moisture content, calorific value, ash content influenced by the type of adhesive derived from glutinous rice so as to obtain the ideal formulation for making briquettes from hazelnut shells. This study used a complete randomised design (CRD) with variations in glutinous rice flour concentration of 20%, 30%, and 40%. The results showed that the concentration of the adhesive used was not significantly different from the value of water content, ash content and calorific value produced. The best quality briquettes were at 40% adhesive percentage, with a calorific value of 5321 cal/gr, 7.2% moisture content, and 5.1% ash content. Pecan shell briquettes with rice flour adhesive are in accordance with the Indonesian national standard (SNI) both from the value of water content, ash content and calorific value.

Abstract

Temperature control plays a critical role in various industrial applications, ensuring optimal process efficiency, product quality, and output. The programmable logic controller (PLC) has emerged as a versatile tool for implementing temperature control systems due to its advanced capabilities in computer control, communication, and automation. This work presents an approach for designing a temperature control systems using Programmable logic controller (PLC). The system employs thermostats, which is a form of temperature sensor to detect and convert temperature values into voltage signals, which are then processed by the PLC through ladder algorithms. The temperature status of the thermostats is used to switch OFF or ON electric heaters in a bid to reduce or increase the temperature of a system. The PLC technology enables continuous monitoring and control of temperature, ensuring precise regulation in industrial settings such as material processing, boiler heating, and kiln operations. Additionally, the paper highlights the advantages of PLC-based temperature control systems, including high efficiency, stability, precision, and remote monitoring capabilities. The findings suggest that PLC-based temperature control systems offer promising solutions for achieving reliable and effective temperature management in diverse industrial environments.

Abstract

The need for energy every year both in the domestic and global increases. Indonesia's energy needs are predicted to increase by 5% each year. Indonesia has renewable energy potential from solar, hydropower, wind, and geothermal sources. The potential of new renewable energy amounted to 442 GW. Of the 442 GW, the greatest potential is owned by 207 GW of solar energy. The high potential of solar energy in Indonesia is because Indonesia is located in the tropics which experiences sunshine time of approximately 6-8 hours per day and the sun continues to shine throughout the year. However, the length of irradiation also has an impact on increasing the temperature of solar panels. The higher the temperature of the solar panel, the output power will decrease and the life of the solar panel is reduced. The use of passive cooling from reference has a lower efficiency increase than active cooling. However, its installation requires lower costs, minimal maintenance, and no additional power requirements. This research will use 20WP monocrystalline solar panels with three cooling variations, namely: 1) with the addition of a thin aluminum plate and Vortex generator 2) By giving a tub of water under the panel 3) the Addition of aluminum fin. The three variations are compared with solar panels without cooling. The results on the first day showed a decrease in temperature of 2.30C with aluminum fin and an increase in power of 6.97% when using a water container. On the second day, a temperature decrease of 2.90C and a power increase of 5.81% when using aluminum fin coolers were recorded.

Abstract

This research aims to analyze and model wheel-based floating energy generation technology. The current energy crisis requires us to look for sustainable solutions to meet energy needs. The Indonesian government has targeted renewable energy use of 23% by 2025, especially in remote areas. One solution to overcome this challenge is energy storage technology. Energy storage using floating technology is an innovative solution that is being developed. In this research, we analyze the design of a floating energy wheel with a capacity of 110 kW as an alternative source of electrical energy. Wheel energy is produced from a combination of buoyancy energy and energy originating from the weight of water which is produced by the difference in fluid density in the water and air environments. The research results show that this floating energy wheel can produce a torque of 7710,62 Nm and a power of 113,83 kW, showing great potential in renewable energy storage applications. Wheel-based floating energy generation technology has the potential to be an innovative solution in renewable energy storage. Further research needs to be carried out on a larger scale and field tests to validate the potential and efficiency of this technology in the real world
