Abstract

Belt conveyor is a fairly simple equipment used to transport load units or bulk materials with a large capacity, the tool consists of belts that are resistant to the transport of solid objects. The sabuk used in this Belt Conveyor is made from various types of materials, for example from rubber, plastic, leather or metal which depends on the type and nature of the material to be transported. The testing process of this tool starts by turning on the Conveyor Belt, the rotation on the Conveyor Belt is constant at a speed of 3.1 m / min and there is no speed setting, the speed of the Conveyor Belt can be known using the Tachometer tool and can be calculated manually using the formula v = s / t where v = speed, s = distance and t = time. When the object is attached to the Conveyor Belt the object will run and pass through the Ultrasonic sensor, when the position of the object is directly under the sensor, the sensor will detect the object based on the height or distance between the sensor and the object, so that Arduino Uno can carry out the work process of the object falls into category A, B or C.

Abstract

The increasing volume of waste in Indonesia, particularly plastic waste, has led to significant environmental challenges due to its continuous accumulation. Pyrolysis offers a sustainable alternative to conventional disposal methods, such as landfilling and incineration, which are known to contribute to pollution. Pyrolysis is a thermochemical decomposition process carried out in an oxygen-deficient environment, converting plastic waste into valuable products, including gas, oil, and char. These products have various applications: the gas can be used as a fuel, the oil as a liquid fuel, and the char as a solid fuel. This study investigates the pyrolysis of three types of plastic feedstocks: high-density polyethylene (HDPE), polypropylene (PP), and a 50:50 mixture of HDPE and PP. The catalysts employed were ZSM-5 zeolite, dolomite, and a mixed catalyst comprising ZSM-5 zeolite and dolomite, with a catalyst-to-feedstock ratio of 0.2:1. The results revealed that the highest oil yields were achieved using the ZSM-5 zeolite catalyst, producing 243 ml from HDPE, 370 ml from PP, and 380 ml from the HDPE-PP mixture. Conversely, the dolomite catalyst yielded the lowest oil production, with 82 ml from HDPE, 20 ml from PP, and 282 ml from the HDPE-PP mixture. Additionally, the ZSM-5 zeolite catalyst demonstrated a consistent increase in the oil production rate every 10 minutes across all feedstocks. These findings highlight the effectiveness of ZSM-5 zeolite in enhancing oil yield during pyrolysis, offering a viable pathway for converting plastic waste into valuable energy resources.

Abstract

Piezoelectric energy harvesters (PEHs) have attracted considerable attention as an alternative approach for converting ambient mechanical energy into electrical power, particularly under low-speed wind conditions. In this study, the performance of a micro-windmill-driven piezoelectric wind energy harvesting system is experimentally investigated with emphasis on the effects of wind speed and mechanical configuration ratios. Experiments were conducted in a controlled wind tunnel environment at wind speeds of 6, 7, and 8 m/s to represent low to moderate airflow conditions commonly encountered in practical applications. Three mechanical configuration ratios, namely 1:3, 1:2, and 1:1, were evaluated to assess their influence on the dynamic response and electrical output of the piezoelectric element. The alternating voltage generated by the piezoelectric harvester was rectified, and the output voltage–time characteristics were recorded over a 60 s testing period using a data acquisition system. The experimental results demonstrate that increasing wind speed significantly improves both the voltage rise rate and the achievable steady-state voltage for all tested configurations, indicating enhanced mechanical excitation and energy conversion efficiency at higher airflow velocities. Among the configurations examined, the 1:1 ratio consistently exhibits the highest output voltage and the fastest response, particularly at wind speeds of 7 and 8 m/s, suggesting an optimal mechanical–electrical coupling. The 1:2 configuration shows comparable performance at lower wind speeds, while the 1:3 configuration produces substantially lower voltage output throughout the test duration, reflecting reduced energy transfer effectiveness. Overall, the findings highlight the importance of mechanical configuration and wind speed in determining the performance of piezoelectric wind energy harvesters. The results provide useful design guidelines for optimizing PEH systems intended for self-powered sensors and other low-power electronic applications operating in low-speed wind environments.
