Sampah plastik merupakan salah satu jenis sampah yang bisa menimbulkan pencemaran lingkungan jika tidak bisa ditangani dengan baik. Salah satu metode untuk mengatasi masalah tersebut adalah dengan mengubahnya menjadi bahan bakar alternatif melalui proses pirolisis. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh laju kenaikan suhu terhadap rendemen dan kualitas produk pirolisis sampah plastik di dalam Rotary Drum Reactor. Bahan baku yang digunakan adalah sampah plastik berupa tas kresek hitam yang bersih dan kering. Bahan tersebut dimasukkan ke dalam reaktor untuk dipanaskan sampai suhu 3500C selama satu jam menggunakan steam-atomizing burner. Variabel dari penelitian ini adalah laju kenaikan suhu di dalam reaktor, yaitu 5, 10, dan 150C/menit. Hasil penelitian menunjukkan bahwa semakin tinggi laju kenaikan suhu, rendemen minyak yang dihasilkan juga semakin besar. Rendemen terbesar yaitu 46% yang dicapai pada laju kenaikan suhu 150C/menit. Hasil uji laboratorium menunjukkan bahwa karakteristik minyak hasil pirolisis mendekati sifat-sifat minyak solar, sehingga bisa dijadikan alternatif bahan bakar mesin diesel di masa depan.
<p>Organic wastes has potential as a renewable energy resource. The waste could be converted as a gaseous fuel through gasification method. The objective of this reserach was to study the performance of gasification of various organic waste using fixed bed updraft gasifier especially in term of production of heat and stability of gas production. The raw material that used are rice husk, sawdust pellet, and wood branch. The stabilization of gas production was measurdd based on the time interval of gas could be burnt. The result shows that the kind of biomass has influenced the heating rate and stability of gas production. Sawdust pellet have the biggest burning stabilisation, that is 45 minute of burning time, compare to rice husk that have 15 minute burning time, and wood branch that have 30 minutes burning time. The main problem of gasification of organic waste was less stabilization of gas production due to low material compaction and uncontinuous mass flow.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
