Abstract

The escalating accumulation of plastic waste demands not only scalable but integrative conversion solutions. Among thermochemical routes, catalytic pyrolysis has emerged as a promising pathway to produce gasoline-range hydrocarbons from plastic polymers compatible with spark-ignition engines. This review critically evaluates recent advancements in pyrolysis of key plastics polypropylene (PP), polyethylene (PE), polystyrene (PS), polyethylene terephthalate (PET), and polyvinyl chloride (PVC) with a focus on fuel yield, hydrocarbon distribution, and engine-level performance. Comparative analysis reveals PP as the most viable feedstock, achieving up to 85% liquid yield and producing oil with high Research Octane Numbers (RON 85–95), outperforming PE and PS in combustion efficiency and emission compliance. However, persistent challenges such as fuel instability, catalyst deactivation, and elevated aromatic emissions particularly from PS complicate real-world deployment. The review further dissects the interplay between catalyst type, reactor design, and post-treatment, highlighting how these variables modulate product quality and engine operability. Notably, 10–20% PP/PE-derived pyrolysis gasoline blends demonstrate near-parity with conventional gasoline in Brake Thermal Efficiency and regulated emissions, without requiring engine modifications. This work bridges molecular-level reaction chemistry with combustion diagnostics and policy-aligned emission metrics, offering a rare multiscale synthesis. By articulating process-emission-performance trade-offs, it provides a strategic reference for researchers and practitioners aiming to scale waste-to-fuel systems within circular economy frameworks.

Abstract

Simalingkar Public Health Service is located in one of one of the 5 districts in Medan with the Red zone status. At the Partner location, it was found that they using hand wash basin with ordinary hand operated tap and it was not optimal to preventing the spread of the Covid-19 virus since some surface of plastic or steel in public health service cannot absorb droplet and preserving the active virus, it could become the transmission vehicle of the virus from one person to the next. Because that area with high touch intensity can pose a risk of transmission of the Covid-19 virus, the solution that will be offered by designing and making an automatic tap hand wash basin by using feet pedals so that there is no need hand to touch the water tap The purpose of this activity is expected that Partners can preventing the spread of Covid-19 by using hands free wash basin on daily health service activities.

Abstract

terakhir ini. Hal ini penting dikarenakan dasar dalam perhitungan konsumsi energi pada proses penguapan air maupun umumnya kehilangan massa cairan di suatu reservoir. Pada penelitian ini dilakukan simulasi secara transient, yang bertujuan untuk mengetahui laju penguapan air laut yang terjadi pada sebuah reservoir atau bak penampung, dengan asumsi radiasi matahari yang dianggap telah diserap oleh bak sebagai fluks panas. Simulasi yang digunakan menggunakan metode CFD (computational Fluid Dynamics) multifasa (Volume of Fluid) dengan perangkat lunak Ansys Fluent. Kondisi batas yang digunakan pada simulasi ini dengan kondisi nilai radiasi sebesar 600 W/m2. Pada hasil simulasi dapat diperolah nilai laju perpindahan massa dan laju perpindahan panas, dengan nilai rata-rata laju selama 1 jam, untuk tanpa kipas 2,78671×10-6 kg/s dan 2049,18 J/s.

Abstract

This research examines the performance of a Diesel engine that uses alternative fuel biodiesel from a mixture of rubber seeds with plastic waste pyrolysis and diesel oil. The plastic waste used is plastic bottle caps, which are processed by pyrolysis to obtain oil. One of the objectives of mixing biodiesel with plastic waste pyrolysis oil is to increase the calorific value of rubber seed biodiesel. The calorific value of rubber seed biodiesel is 39.95 kJ/kg, and the calorific value of plastic waste pyrolysis oil is 46.55 kJ/kg. Mixing rubber seed biodiesel with plastic waste pyrolysis oil increases the calorific value of rubber seed biodiesel by around 9.63%-13.63%. Experimental results show that there is a reduction in exhaust emissions when using biodiesel for opacity of 7.51-66.08%, CO 12.5-50%, HC 7.14-62.96% and an increase in CO2 emissions of around 3.08-84.62%. Tests using biodiesel were carried out without modifying the Diesel engine.

Abstract

Studi ini menganalisis pengaruh penambahan metanol pada minyak pirolisis limbah plastik terhadap emisi gas buang mesin Otto stasioner sebagai upaya meningkatkan kualitas pembakaran bahan bakar alternatif. Penelitian ini bertujuan untuk menganalisis pengaruh fraksi metanol dalam bahan bakar minyak pirolisis limbah plastik terhadap emisi HC, CO, CO₂, O₂, dan nilai lambda pada mesin Otto stasioner serta mengidentifikasi komposisi campuran optimum berdasarkan kinerja emisi. Pengujian dilakukan pada tiga putaran mesin yaitu 1500 rpm, 2000 rpm, dan 2500 rpm dengan parameter emisi yang diukur meliputi HC, CO, CO₂, O₂, dan nilai lambda. Hasil pengujian menunjukkan bahwa campuran 5% metanol dengan 95% pirolisis plastik memberikan performa emisi terbaik, ditandai dengan kadar HC dan CO yang lebih rendah, CO₂ lebih tinggi, serta O₂ yang lebih rendah dibandingkan campuran lainnya. Sementara itu, pada campuran 10% dan 15% metanol terjadi peningkatan emisi HC dan CO serta penurunan CO₂, yang menandakan pembakaran kurang sempurna. Dengan demikian, penambahan metanol dalam jumlah terbatas mampu meningkatkan efisiensi pembakaran dan menekan emisi berbahaya dari mesin Otto stasioner berbahan bakar campuran pirolisis plastik.
