PYROLYSIS OF ALANG – ALANG (IMPERATA CILINDRICA) AS BIOENERGY SOURCE IN BANTEN PROVINCE INDONESIA

摘要: Bahan bakar fosil sumber energi memiliki keterbatasan dan tidak terbarukan, penggunaan bahan secara terus menerus mengakibatkan krisis energy lingkungan. Rumput liar pada saat ini potensi untuk dikembangkan sebagai generasi kedua biomasa. Hal keuntungan seperti tumbuh dengan cepat, mudah tumbuh, perawatan yang minimal, dapat lahan kritis tersedia dalam jumlah banyak. Dalam upaya mengembangkan biomasa, penelitian sistematis memberikan perspektif ekologi teknologi proses bioenergi dari alang – di Provinsi Banten. Pada karakterisasi dilakukan menentukan sifat bioenergy. Sedangkan fixed bed pirolisis mengidentifikasi produksi bio-oil pirolisis. Sementara analisis melihat chemical building block energi. Analisis kimia fisika melalui thermogravimetric analysis, proximate elemental compositional calorific value. lakukan Gas Chromatography–Mass Spectrometry (GC-MS). Dari hasil mengindikasikan bahwa nilai kalori 18,05 MJ/kg, ash konten rendah, tinggi kandungan volatile. GC/MS menunjukan komponen utama dikelompokan ke furan, ketone, phenol anhydrosugar merupakan platform dikonversi menjadi Fixed pyrolysis atau menunjukan, yield meningkat sebagaimana peningkatan temperatur puncaknya suhu 500 0C persentase 37,91%. Kata Kunci: Alang - alang, Pirolisis, GC/MS, Thermogravimetric Bioenergi   ABSTRACT Fossil fuel as a source of have limitation and are non-renewable. Continuous utilisation fossil fuels can lead to crisis environmental impact. Perennials grasses (alang alang) currently being developed suitable second-generation biofuel feedstock. It has advantages such rapid growth rate, easy grow, minimal maintenance utilise marginal land without competing with food supply. Taking into account the various challenges attributed transformation biomass for production, this work systematically looks at ecological perspective availability bioenergy production from in Banten Province. Biomass characterisation is carried out determine properties potential. study was conducted predict potential process. identify blocks value-added chemicals alang. The physicochemical feedstock thoroughly evaluated using analysis through GC / MS. Characterisation results indicate that value 18.39 low content high percentage volatile matter. Analysis (GC-MS) showed majority groups contained anhydro-sugars. Phenolic furanic were found major compounds bio oil. Phenolic, furanic, ketonic anhydrosugars promising renewable derived be further converted or fuels. fixed-bed increases temperature peaks 500°C 38.79%. Keywords: Pyrolysis, Bioenergy
