Abstract

Di Dusun II, Kecamatan Medang Deras masyarakat giat meningkatkan kesejahteraan pereokonomiannya dengan mengoptimalkan bidang usahannya dan salah satunya pembuatan kripik ubi. Dalam upaya meningkatkan produksi kripik ubi dengan alat pemotong bahan tersebut guna meminimalis waktu proses. Adanya penyuluhan dan pelatihan pembuatan dan penerapan alat pemotong makanan ringan dalam upaya meningkatkan produktivitas industri, kepada kelompok pengusaha kecil di daerah tersebut mendapat tanggapan dan dukungan sangat besar. Penyuluhan membahas tentang manfaat tentang keuntungan pemakaian alat pemotong kripik. Pelatihan dilakukan untuk membimbing langkah-langkah pembuatan alat pemotong dan pengoperasiannya. Dengan adanya penyuluhan tersebut masyarakat mampu membuat dan mengembangkan alat tersebut serta mampu mengoperasikannnya.

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

The National Energy Policy to develop the use of renewable energy has opened up opportunities for industry to develop the use of biomass. A study on the use of palm shells as a substitute for industrial diesel in a thermal oil heating system at a natural rubber resin factory in North Sumatra has been carried out. All information and data on the operation of TOH were obtained through secondary data collection and direct discussions in the field. The secondary data obtained include the type and specification of the heater, the characteristics of the thermal oil (type, flow rate, temperature inlet and outlet of the heater), fuel consumption/hour and the characteristics of palm shells. From the study conducted, it can be concluded that during the process of heating thermal oil which takes place gradually in the TOH system using industrial diesel, it has a heat capacity of 1.500.000 kcal/hour, but the maximum heat that is useful for heating thermal oil is 694,396 kcal/hour with maximum thermal efficiency is 80.69%. Estimated consumption of palm kernel shells required to heat thermal oil on the assumption of 70% thermal efficiency as a substitute for energy supplied by industrial diesel is 237 kg/hour. The savings from this fuel replacement is estimated Rp.3.286.800.000/year.
