Abstract


Melon fruit waste with high sugar and water content is potential as a substrate for hydrogen production by dark fermentation. This study investigated the performance of biohydrogen production from melon fruit waste in a stirred tank reactor with initial concentration of 13100 mg sCOD/L, in room temperature, initial pH of 7 and controlling final pH at 5.5 by adding NaOH. The fermentation was carried out for 24 hours. The value of pH, volatile solid (VS), soluble chemical oxygen demand (sCOD), volatile fatty acid (VFA), biogas volume, hydrogen content, and cell concentration was analized every hour to determine the performance of reactor. Hydrogen content reached 16.20% with hydrogen production rate (HPR) of 458.12 mL/Lreactor/day in the standard temperature and pressure (STP) condition. Substrate consumption at the end of fermentation reached 24.61% of sCOD and 78.28% of VS. Metabolite products were dominated by acetate and butyrate with butyrate to acetate ratio of 7:6.  The kinetic of product formation was evaluated by the kinetic model of Gompertz. Meanwhile the kinetics of cell growth was approximated by logistics model

Sampah buah melon yang cukup melimpah dan kaya akan gula dan air sangat berpotensi sebagai substrat untuk produksi biohidrogen secara fermentasi gelap. Pada penelitian ini dipelajari kinerja produksi biohidrogen dari sampah buah melon menggunakan reaktor tangki berpengaduk. Konsentrasi awal substrat 13.100 mg sCOD/L pada suhu ruang, pH awal 7 dan dan dilakukan kontrol terhadap pH akhir fermentasi agar tidak turun lebih rendah dari pH 5,5 dengan penambahan NaOH. Fermentasi berlangsung selama 24 jam dan setiap jam dilakukan analisis terhadap pH, volatile solid (VS), soluble chemical oxygen demand (sCOD), volatile fatty acid (VFA), volume biogas, kadar hidrogen dan konsentrasi biomassa untuk mengetahui kinerja reaktor. Kadar biohidrogan yang diperoleh sebesar 16,20% dengan laju produksi hidrogen sebesar 458,12 mL/Lreaktor/hari pada keadaan STP. Konsumsi substrat pada akhir fermentasi mencapai 24,61% sCOD dan 78,28% VS. Produk metabolit dominan adalah asetat dan butirat dengan ratio butirat per asetat sebesar 1,2.  Kinetika pembentukan hidrogen dipelajari melalui model kinetika persamaan Gompertz. Sedangkan kinetika pertumbuhan sel didekati dengan model kinetika persamaan logistik.
