Abstract

Corn is a superior agricultural product for the Giri Harjo I farmer group, Girikikis Village, Giriwoyo District, Wonogiri. However, farmers process and peel corn manually, so it takes a more time and inefficient. In order to overcome this problem, this community service designed and made a corn sheller machine that was used to simplify and increase the productivity in the corn harvesting process. This service activity begins with the delivery of the corn sheller machine to the farmer group, then exposure and training on the use of the machine. Corn shelling is accomplished by inserting the corn into the sheller shaft, after which the grinding knife separates the corn kernels from the cob. The shelling test results show that this machine works well, is practical to use, is highly portable, the production process is faster, the corncobs are not damaged, and the electric power consumption is low. This machine has a 0.5 HP motor and a production capacity of 183 kg/hour for shelling corn kernels.

Abstract

Corn shelling tools have developed in Indonesia ranging from very simple corn shellers to mechanical corn shellers. However, the maize sheller with a medium-scale capacity has not been well developed. The research objective was to design and analyze the performance of a medium-capacity portable corn sheller machine to meet the maize harvest processing process, which can increase productivity, the quality of maize shelled with medium-scale capacity and also develop a new shelling tool design. This research was conducted in 3 stages, namely field observation, design, and machine performance. The results showed a corn sheller machine with a 0.5 hp electric motor. The results of the work show that the speed of the shelling process is very influential on the results of the shelling. The higher the speed of the shelling process, which is 2400 rpm, the better or no leftover corn is shredded.

Abstract

Currently, carbon derived from biomass waste or residues is being intensively utilized as electrodes due to its excellent electrical properties, including high conductivity, appropriate porosity, and a specific surface area suitable for supercapacitor applications. Despite its advantages, the performance of supercapacitors made from biomass-derived carbon is insufficient for engineering applications because of the challenges in obtaining the mesoporous structure of activated carbon (AC). Therefore, this study highlights the potential of biomass-based carbon as the electrodes of a highly efficient supercapacitor, which can facilitate highly efficient current transport in energy storage systems. It comprehensively discusses various biomass material sources and activation methods to produce carbon, with a focus on the physical and electrical properties. Initially, the study discusses carbon activation methods and mechanisms to understand why activating agents and electrolyte solutions have a high specific surface area and specific capacitance. It then concentrates on the chemical activation method and its importance in making AC useful as an efficient electrode. Finally, in this study, various biomass sources were discussed to highlight the performance of supercapacitors electrodes originating from agricultural and wood residues relating to the specific capacitance and capacitance retention. Based on the obtained results, it is concluded that biomass-based carbon materials could be the most advantageous platform material for energy conversion and storage.

Abstract

ABSTRACT Almost all households in Indonesia use a refrigerator as a place to store food that is more durable. But behind these needs, refrigerators are identified as one of the household appliances that use high electrical energy. Therefore, this study aims to examine the use of Tube in Tube Heat Exchanger (TiTHX) with refrigerant R290 in the refrigerator system to reduce household electricity consumption. This research was conducted experimentally by varying the 3 diameter ratios on TiTHX. The results showed that the use of TiTHX with the most optimum value was obtained at the variation diameter ¼ : ½ increasing refrigerator performance by 3.7%. and also reduce the consumption of electricity costs up to Rp. 17,544.44 per month. This is because the difference between the evaporation pressure and condensation pressure is smaller in systems using TiTHX which then results in lower compression work.

Abstract

The cabin car temperature will increase when parked in direct sunlight, so the energy required to cool cabin space by the air conditioner will be higher. This study aims to investigate using a thermoelectric cooling system as an alternative to a chiller system to supply cold air to the car cabin under different cooling methods for parked cars. Experimental testing of thermoelectric cooling systems was conducted to produce cold air that can be applied to car cabins as an alternative to conventional air conditioners. The thermoelectric cooling system was varied with single and double TEC modules. The double TEC modules are arranged in a series of electrical and parallel thermal arrangements. A cooling water block using a mixture of water and ethylene glycol with variations of 0.4 lpm, 0.5 lpm, and 0.6 lpm was added to the hot side of the thermoelectric module. The result shows that the thermoelectric cooling system can work properly during the 2-hour test, which constantly supplies air to the cabin space between 20-25 °C, depending on the configuration of the cooling system. The highest COP of 0.84 was obtained when using the double TEC with heatsink and added 0.5 lpm water cooling system, while the lowest COP of 0.53 was obtained when using the single TEC module without a cooling water block.

Abstract

Heatsink is composed of square or circular-shaped base plates connected to fins on one side. Fluid flow within the heatsink typically occurs through natural convection, where colder air flows into the hotter fin region and exits through the fin tips. In this study, we conducted numerical simulations using Solidworks 2021-2022 Research Licence software to investigate three different heatsink models with distinct shapes, aiming to determine the most effective cooling rate. The thermal simulation results revealed that the heatsink design with square fins exhibited lower maximum temperatures, making it recommended for applications utilizing natural convection. Additionally, heat sinks with thinner fins have a larger surface area, accommodating more fins compared to thicker ones, which affects the heat transfer efficiency within the heat sink.
