Abstract
Kelapa sawit merupakan komoditas yang setiap tahunnya selalu mengalami peningkatan, oleh sebab itu limbah yang dihasilkan seperti TKKS juga mengalami peningkatan. Karena struktur lignin pada TKKS cukup tinggi menyebabkan TKKS sulit terdegradasi dalam pembuatan biogas, sehingga perlu dilakukan pretreatment untuk dapat memecah struktur lignin tersebut. Penelitian ini melakukan pretreatment pada TKKS menggunakan bakteri (Comamonas testosteroni dan Lysinibacillus sphaericus) dan penambahan MnCl2. Proses pretreatment menggunakan 5 sampel dengan 3 kali perulangan, terdiri dari 1 sampel untreated dan 4 sampel treated. Dalam pembuatan biogas menggunakan metode Biochemical Methane Potential (BMP) untuk mengetahui besar gas metana yang dihasilkan dengan lama pengamatan 28 hari dalam kondisi anaerob. Uji BMP menggunakan 7 sampel dengan 3 kali perulangan, terdiri dari 2 sampel kontrol (blank dan α-selulosa) dan 5 sampel pretreatment. Penelitian ini menggunakan metode rancangan acak lengkap dengan faktor pemberian bakteri dan MnCl2, parameter proses pretreatment menggunakan pengujian pH, susut berat, Total Suloble Phenol (TSP), Total Gula Reduksi (TGR), dan kadar lignin. Sampel TKKS dengan bakteri Lysinibacillus sphaericus dan MnCl2 menghasilkan nilai TSP, TGR, dan susut berat yang lebih tinggi dibanding dengan sampel lain. Hasil TSP dan TGR setelah pretreatment yang dilakukan mampu memberikan degradasi TKKS yang baik. Adapun berdasarkan kandungan lignin yang diperoleh, pemberian MnCl2 masih kurang berpengaruh dalam memberikan peningkatan degradasi lignin, dimana pada bakteri Comamonas testosteroni memberikan peningkatan dalam degradasi lignin sebesar 0,06% sedangkan pada bakteri Lysinibacillus sphaericus tidak memberikan peningkatan degradasi lignin. Sampel TKKS mempunyai juga berpotensi digunakan sebagai bahan produksi biogas atau metana. Karena berdasarkan karakteristik fisik dan nilai kalor pada sampel pretreatment menghasilkan peningkatan nilai kalor dan kandungan organik (TS dan VS). Hasil potensi metana spesifik (SMP) tertinggi diperoleh sampel TKKS dengan bakteri Lysinibacillus sphaericus dan MnCl2 sebesar 0,248 m3/KgVS dan hasil SMP terendah diperoleh sampel TKKS untreated sebesar 0,049 m3/KgVS
English Abstract
Palm oil is a commodity that always increases every year, so the wastage produced such as EFB also increases. Because the lignin structure in OPEFB is quite high, it is difficult to degrade OPEFB in the manufacture of biogas, so it is necessary to do a pretreatment to be able to break down the lignin structure. In this study, bacteria (Comamonas testosteroni dan Lysinibacillus sphaericus) and the addition of MnCl2 were used to pre-treat OPEFB. The pretreatment process used 5 samples with 3 repetitions, consisting of 1 untreated sample and 4 treated samples. In making biogas using the Biochemical Methane Potential (BMP) method to determine the amount of methane gas produced with 28 days of observation under anaerobic conditions. The BMP test used 7 samples with 3 repetitions, consisting of 2 control samples (blank and α-cellulose) and 5 pretreatment samples. This study used a randomized design method with bacteria and MnCl2 as a factor, the parameters of the pretreatment process were pH, weight loss, Total Soluble Phenol (TSP), Total Reducing Sugar (TGR), and lignin content. Compared with other samples, the OPEFB sample containing Lysinibacillus sphaericus and MnCl2 produced higher TSP, TGR and weight loss values. The results of TSP and TGR after a pretreatment were able to provide good OPEFB degradation. Meanwhile, based on the lignin content obtained, the administration of MnCl2 was still less influential in increasing lignin degradation, where in the Comamonas testosteroni bacteria it gave an increase in lignin degradation by 0.06% while in Lysinibacillus sphaericus bacteria it did not increase lignin degradation. OPEFB samples have the potential to be used as a biogas or methane production material. Because of the physical characteristics and calorific value of the pretreatment samples resulted in an increase in calorific value and organic content (TS and VS). Highest specific methane potential (SMP) The yield was obtained from OPEFB samples with Lysinella sphaericus and MnCl2 at 0.248 m3/KgVS and the lowest SMP results obtained by untreated OPEFB samples of 0.049 m3/KgVS
