Abstract

The escalating volume of plastic waste has become a critical environmental challenge, highlighting the need for innovative solutions to repurpose it into valuable construction materials. This study aimed to design and develop a pneumatic-based eco-paving block printing machine that uses plastic waste as its primary raw material. The research methodology encompassed the design and simulation of pneumatic circuits, structural analysis involving stress distribution, displacement, and factor of safety (FOS), and strength testing of the fabricated eco-paving blocks. The machine was equipped with a pneumatic cylinder measuring 80 × 75 mm, operating at a pressure of 6 bar and generating a maximum pressing force of 300 kg. The simulation results confirmed that the maximum stress and displacement remained within safe limits, with a minimum FOS of 8.4, thereby ensuring a stable and reliable design. Testing of the eco-paving blocks revealed compressive strengths ranging from 38 to 54 MPa, surpassing the requirements of the SNI 03-0691-1996 standard. This study demonstrates that a pneumatic-based eco-paving block printing machine effectively transforms plastic waste into high-quality construction materials compliant with national standards, offering a practical solution to the plastic waste crisis while promoting sustainability in the construction industry.

Abstract

In Lohbener Village, Indramayu Regency, small and medium enterprises (SMEs) produce tofu using traditional methods, where the soybean pulp filtering process requires significant time and physical effort. To address this issue, a soybean pulp filtering machine was developed to improve filtering efficiency. The machine was tested with three different input loads—5 kg, 10 kg, and 15 kg—at a constant speed of 57 rpm. The filtering times recorded were 3 minutes 10 seconds, 5 minutes 17 seconds, and 8 minutes 21 seconds, respectively, determined by the point at which no more liquid discharged from the system. The final weights of the filtered soybean pulp were 1.5 kg, 5.7 kg, and 7.4 kg, respectively. These weight differences were influenced by an unbalanced soybean-to-water ratio, which affected extraction effectiveness. The average moisture content of the filtered pulp was 18% for the 5 kg load, 14.90% for 10 kg, and 15.17% for 15 kg. These results indicate that the use of the filtering machine significantly improves filtering efficiency compared to manual methods, in terms of time, output, and pulp quality. Overall, the machine has a positive impact on increasing productivity and product quality in tofu production at the SME level.

Abstract

Indramayu is the largest rice barn area in Java, so it contributes waste from the rice production process, but the waste processing process is less productive or there are very few enthusiasts. So there is a very big opportunity by utilizing waste which is more useful, namely by processing it into fish pellets which have a high price value compared to other processing methods. The design of the rice husk grinding machine uses a type 32 disk mill knife and a type 32 fish pellet printer that will print 3 mm pellets with a machine frame dimension of 849 x 597 x 918. The frame of this machine uses 40 x 40 x 1.35 mm hollow iron. The specifications of this fish machine consist of three main components, namely a husk refiner, a pellet dough mixer, and a fish pellet molder driven by a combustion engine with the motor power and speed used, namely a refiner power of 1.82 HP with a speed of 3600 rpm, a mixer power of 1.86 HP with a speed of 771.42 rpm, a molding power of 0.56 HP with a speed of 771.42 rpm. So the total power used for this machine is 5.5 HP or 4.1 kw. So it can be seen that the motor power is 5.5 HP < 7 HP, so a 7 HP drive motor can be used.

Abstract

ABSTRACT – Manual tofu cutting is often time-consuming and less efficient, necessitating innovation to enhance productivity. This study aims to design an automatic tofu cutting machine as a replacement for the manual cutting process. The method used is Participatory Rural Appraisal (PRA) with an experimental approach. The design process involves simulations to determine the machine's technical specifications, resulting in a minimum pneumatic piston diameter of 24 mm, an inertia of 88,281.25, and a maximum stress of 0.24 N/mm². Testing shows that the machine can cut 112 pieces of tofu in 3.8 seconds. These results indicate that the automatic tofu cutting machine significantly improves the efficiency and speed of the cutting process compared to manual methods. This research contributes to the development of more efficient food processing technology applicable to small-scale industries.

Abstract

This study examines the performance of a thermal management system for 18650 lithium-ion batteries using a circular placement configuration and a forward-curved fan. Experiments were conducted with variations in fan speed, the number of fan blades, and battery positioning (aligned or zigzag) to observe their effects on temperature and temperature distribution during the battery discharge process. The results showed that increasing fan speed significantly reduced battery temperature to around 30-33°C and improved temperature distribution uniformity with a standard deviation ranging from 0.5 to 1.21°C. Meanwhile, variations in the number of fan blades and battery positioning had an insignificant impact on temperature reduction but did influence temperature distribution uniformity, with the lowest standard deviation of 0.5-0.6°C observed in the three-blade variation. The zigzag positioning provided a more uniform temperature distribution compared to the aligned positioning, with a standard deviation of 0.51-0.97°C
