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

Salah satu alat pemanen energi alternatif adalah generator Winbelt. Winbelt adalah alat konversi energi yang mengubah gerakan angin menjadi energi listrik. Dalam generator Winbelt terdapat suatu alat induksi eletromagnetik yang terdiri dari magnet dan kumparan. Karena gerakan angin yang mengenai belt, sehingga menggerakan magnet secara bolak balik terhadap kumparan, maka terjadilah induksi elektromangnetis yang dapat  menghasilkan listrik. Penelitian ini membahas pengaruh lebar Pita Winbelt terhadap energi listrik yang dihasilkan dengan variasi kecepatan angin yang diberikan. Metodologi penelitian melibatkan pembuatan beberapa prototipe Windbelt dengan panjang pita yang sama namun berbeda dalam hal tingkat kelebaran. Selanjutnya, prototipe tersebut ditempatkan dalam lingkungan yang dapat mensimulasikan angin atau aliran udara yang cukup untuk menghasilkan getaran pada pita. Tegangan listrik yang dihasilkan oleh setiap prototipe diamati dan diukur menggunakan perangkat pengukur yang sesuai. Setelah dilakukan pengukuran, didapatkan  nilai tengangan listrik tertinggi dihasilkan pada variasi lebar Pita 18 mm dan dengan kecepatan angin 3.0 m/s  sebesar 2,62 volt.

Abstract

The PLC System in Vertical Plastic Injection Molding Machine is an automated electrical system designed with sensor inputs controlled by a PLC Mitsubishi FX0s-20MR. It is supplemented with additional devices such as Proximity switches and Thermocouple PID-CX100. The research aims to analyze the heater temperature to control the movement of the injection piston for controlled movement, enhancing the efficiency of the molding injection process, and preventing operational errors that could affect the machine's condition, performance, and the molding results. From the experiments conducted, it was found that the settings producing specimens with near-perfect or perfect results were in experiments number 5 and 6. The injection time in these experiments was successfully adjusted using a timer setting in the PLC program, with an automatic injection time of 15 seconds. Based on these results, it can be concluded that the optimal settings for the molding process using PP material in this equipment are a temperature of 200-210°C, pressure of 4-5 bars, and injection time of 15 seconds.

Abstract

Piezoelectric energy harvesters (PEHs) are gaining attention for their ability to generate electrical energy from environmental vibrations, with applications in various industries. This study focuses on optimizing the performance of a PEH using a cantilever system driven by wind energy through the impact of windmill blades. The objective is to evaluate how the number of windmill blades affects the PEH's voltage output and vibration stability. Experiments were conducted in a wind tunnel with a 250 mm × 250 mm cross-section equipped with a 12-inch blower to generate airflow. Three windmill configurations—3 blades, 4 blades, and 5 blades—were analyzed for output voltage and deflection of two PVDF-based PEHs placed at a 30° angle. Results indicate that the 3-blade configuration produced the highest voltage (1.79V), 4% and 43% higher than the 4-blade (1.71V) and 5-blade (1.01V) configurations, respectively. This configuration also exhibited maximum deflection and lower frequency vibrations. Increasing blade count led to higher frequency vibrations but reduced deflection and voltage output. The study highlights that fewer blades result in greater deflection and better energy harvesting performance. These findings contribute to ongoing research in PEH systems, offering insights into optimizing energy harvesting from fluctuating wind conditions by balancing deflection amplitude and vibration frequency.

Abstract

In the sheet metal forming process within the automotive and heavy machinery industries, the Dandori frame component in the die system plays a crucial role as a compressive load-bearing support. This study aims to analyze the static performance of the Dandori frame structure in a press machine using SAPH440 material. The method employed is the Finite Element Method (FEM) based on SolidWorks software to evaluate displacement, von Mises stress, and the factor of safety parameters under load variations of 1000 kg and 2000 kg. Simulation results show that the maximum deformation is only 0.032 mm, indicating high structural stiffness. The maximum stress recorded is 14.286 MPa, uniformly distributed without excessive concentration, and well below the material's yield strength. Meanwhile, the factor of safety is evenly distributed with a value of 3 throughout the structure, indicating a safe design condition. Overall, the simulation results demonstrate that SAPH440 is a suitable and effective material for use in Dandori die frames under static load applications.
