Abstract:

“Penelitian ini bertujuan untuk mengetahui potensi produksi biogas yang dihasilkan daripemanfaatan bio-limbah perhotelan seperti limbah dapur (kitchen) dan limbah lumpur (sewage)dengan penambahan inokolum kotoran hewan. Jumlah material kering (total solid, TS) darilimbah hotel akan dikaji untuk diketahui pengaruhnya terhadap produksi biogas yang dihasilkan.Penelitian dilakukan secara eksperimen dengan variasi TS sebesar 3, 4, 5 gram ke dalamsebuah biodigester skala laboratorium kapasitas 1000ml. Pengukuran kinerja dari biodigesterdiamati selama 40 hari dan dilakukan pengkondisian pH pada digester kontrol. Pengujiankandungan gas metana dilakukan secara langsung menggunakan metode absorpsi CO2 Brigongas tester. Hasil penelitian menunjukkan bahwa dengan mengkondisikan pH pada rentang 6,8-7,5 merupakan kondisi ideal bagi bakteri metana sehingga mempengaruhi produksi biogas yangdihasilkan. Komposisi 5 gram TS sewage dengan pH dikondisikan menunjukkan volume spesifikbiogas paling tinggi. Sedangkan persentase gas metana yang dihasilkan tidak memiliki korelasilangsung terhadap komposisi material kering dan menunjukkan fenomena yang hampir seragamKata kunci : Limbah perhotelan, inokolum, biogas, total solidThis study aims to determine biogas production using organic waste as raw material from hotelindustries such as kitchen waste and sewage sludge with the addition of inokolum. Total drymatter (total solid, TS) of organic waste is studied to determine its effect on the biogas production.Experiments was conducted with a variation of TS of 3, 4, 5 grams into a biodigester laboratoryscale of 1000ml. Measurement of the performance of the biodigester was observed for 40 daysand the pH condition in the digester was controlled. Methane gas content was done directly usingBrigon CO2 gas tester. The results showed that the conditioned of pH 6.8 to 7.5 are found as theideal conditions for methane bacteria to produce of biogas. Composition of 5 grams TS sewagewith a conditioned pH showed the highest specific volume of biogas production. While thepercentage of methane gas that is produced does not have a direct correlation to the compositionof TS and show the phenomenon that is almost uniformlyKey words: hotel wastes, inoculum, biogas, total solids”
