Abstract

The global energy crisis caused by the limits of oil reserves urging the needs for alternative energy solution, including a pyrolysis-based oil energy. In this study, we investigate the pyrolysis of corn cob biomass with varying particle sizes (3 mesh, 5 mesh, 7 mesh, and 10 mesh) to evaluate its effect on product yields and physical properties. Each experiment was conducted for 90 minutes using 300 grams of feedstock, pre-dried in a microwave oven at 120°C for 2 hours. The results revealed that the bio-oil yield decreased with smaller particle sizes, from 31.52% at 3 mesh to 26.12% at 10 mesh. Conversely, bio-char yield increased from 37.48% to 46.47%, while bio-gas yield decreased from 31.00% to 27.42%. This suggests that excessively small particle sizes reduce bio-oil yield due to uncontrolled reactions despite their higher surface area. The bio-oil density ranged between 1.0235 and 1.0353 g/ml, indicating consistent physical properties across particle sizes. The inlet and outlet temperatures of the reactor (T1 and T2) and condenser (T3 and T4) remained relatively increasingly stable, indicating consistent condensation of pyrolysis gases into liquid bio-oil. This study has successfully provided an insight into the optimization of particle size of the waste processing of corn cob into energy by using the pyrolysis method.

Abstract

Piezoelectric energy harvesters (PEHs) convert mechanical energy into electricity. They operate based on pressure or vibration. One method for inducing vibration in PEHs is vortex-induced vibration (VIV), which harnesses wind energy using a bluff body. In this study, the researchers investigated the output voltage generated by PEHs at different altitudes, specifically 6.25 cm and 12.5 cm. Both experimental and simulation approaches were employed. The experimental setup included a PEH composed of a piezoelectric bimorph and a rectangular-trapezoid substrate. Wind speeds of 5, 7, and 9 m/s were tested in a wind tunnel with a cross-section of 250 mm x 250 mm. The simulation utilized the finite element method to explore wind flow patterns. Notably, the results revealed that PEHs positioned at an altitude of 6.25 cm generated higher voltages than those at 12.5 cm. At an altitude of 6.25 cm, each wind speed's maximum electrical voltage values are 4.18 volts, 4.67 volts, and 5.13 volts, respectively. The maximum electric voltage value at a height of 12.5 cm for each wind speed is 2.1 volts, 3.94 volts, and 4.44 volts, respectively. This phenomenon is attributed to the narrowing of the wind tunnel’s inlet area due to the presence of a bluff body, leading to increased air velocity along the tunnel walls. Consequently, a vortex forms near the square bluff body, resulting in pressure fluctuations that induce PEH vibration and generate voltage.

Abstract

Vegetable oil, obtained from plants such as coconut or Jatropha curcas, serves as a valuable renewable energy source. Nonetheless, it presents certain limitations in comparison to diesel fuels, namely, low volatility and high viscosity. One straightforward approach to overcome these limitations is the addition of high-volatility oil and low-viscosity oil. In this study, we incorporated 10% clove oil into coconut oil and Jatropha curcas oil. Fuel properties, including density, viscosity, flash point, and heating value, were measured in accordance with international standards. Additionally, Thermogravimetric Analysis (TGA) testing was performed to detect decomposition during the heating process. The findings indicated that the addition of clove oil increases density (from 0.922 g/ml to 0.934 g/ml), while other properties decrease, such as viscosity (from 30.12 cst to 27.7 cst), flash point (from 286°C to 182°C), and heating value (from 37.1 MJ/kg to 35.8 MJ/kg). TGA demonstrated that the inclusion of clove oil resulted in increased decomposition within the temperature range of 200°C–400°C, suggesting that clove oil falls into the category of medium-volatile oils. Although the addition of clove oil were able to modify the fuel properties of vegetable oil, it did not align with the characteristics of conventional diesel fuel and necessitates further modification for practical implementation

Abstract

This research investigates the properties and performance of fuel blends comprising biodiesel, Calophyllum inophyllum oil (Nyamplung), and essential oils. Biodiesel, a renewable energy source, has gained significant attention due to its low sulfur content, high calorific value, and biodegradability. Experimental investigations involved blending biodiesel with Nyamplung oil and essential oils (clove oil, pine oil, and turpentine oil) in varying proportions. Fuel properties, including density, viscosity, and flash point, were analyzed to assess combustion characteristics. Additionally, engine performance parameters such as torque and exhaust gas temperature (EGT) were evaluated to understand combustion efficiency and engine health. The results revealed that the addition of Nyamplung oil and essential oils increased the density and viscosity of the fuel blends compared to pure biodiesel, impacting atomization and combustion processes. Despite higher viscosity potentially causing ignition delay, flash points decreased due to the presence of essential oils, enhancing safety during storage and handling. Torque measurements indicated variations in engine performance among fuel mixtures, with incomplete combustion observed in blends containing essential oils. EGT measurements further highlighted differences in combustion completeness, with lower temperatures observed in pure biodiesel due to improved atomization and complete combustion.

Abstract

The development of technology demands prospective workers to possess operational skills for equipment in industries, one of which relies on automation. A widely used example of automation technology in the industrial world is Programmable Logic Control (PLC), enabling the automatic control of industrial equipment with ease of scalability. In this context, vocational high school (SMK) students, representing a talent pool for the industrial sector, are required to understand, apply, and possess skills in operating PLC-based industrial equipment. However, to impart such skills, schools often face challenges in acquiring practical equipment, where the costs of which tend to be relatively high. In this community service (Abdimas) program, the team develops demonstration tools for industrial automation, specifically focusing on pneumatic actuators based on PLC. The partner and target in this community service program is SMK Bina Industri located in Ds. Jatiwangi, Kec. Cikarang Barat, Kab. Bekasi. The implementation of this program is carried out through several stages, including (1) identification of partner’s needs; (2) development of demonstration tools; (3) training on the use of demonstration tools; and (4) the handover of the demonstration tools. SMK Bina Industri highly appreciates the implemented program and encourages the development of a partnership that goes beyond the focus on developing demonstration tools and grants. It is expected to include capacity-building activities such as seminars/workshops for teachers and students. This program has successfully developed economical yet effective demonstration tools, opening opportunities for partnerships between universities and vocational high schools in embracing the Golden Indonesia's vision of 2045.
