IN BATCH SYSTEM TO PRODUCE BIO-METHANE}, volume={8}, url={https://journal.ipb.ac.id/index.php/jurnalikt/article/view/15824}, DOI={10.29244/jitkt.v8i2.15824}, abstractNote={<em>This study</em><em> aimed to determine the potential of bio-methane produced by <span style="text-decoration: underline;">Gracilaria</span></em> sp.<em> in a batch system.</em><em> The experiment was conducted in batch system and it was initiated by acclimatization process (12 days) and ended methane production process (30 days). The results showed that biochemical properties of <span style="text-decoration: underline;">Gracilaria</span> </em>sp.<em>  are carbohydrate 65.46 ± 0.58%, lignin 13.20 ± 2.23%, TOC (Total Organic Carbon) 33.39 ± 0.23%, Nitrogen 1.12 ± 0.01%, and C/N ratio 29.82. Acclimatization proceeded successfully and it was indicated by 62.7 L biogas of 4.025 L of substrate <span style="text-decoration: underline;">Gracilaria</span> </em>sp.<em> produced within a pH range of 6.2 - 7.1. </em><em>The batch</em><em> method of anaerobic biodegradation showed that 4 kg of <span style="text-decoration: underline;">Gracilaria</span> </em>sp.<em> can produced 131.1 L of biogas containing methane and 46.7 L or 11.6 L CH<sub>4</sub> /kg.</em&gt;}, number={2}, journal={Jurnal Ilmu dan Teknologi Kelautan Tropis}, author={Kawaroe, Mujizat and Hasanudin, Udin and Krisye.}, year={2017}, month={Apr.}, pages={595-603} }
