Penelitian ini bertujuan untuk mengetahui pengaruh penambahan ampas tahu dalam pembuatan vermicompost dengan bahan dasar sludge biogas kotoran sapi pada berbagai komposisi ampas tahu yang berbeda. Penelitian terdiri dari empat perlakuan, yaitu perlakuan pertama 0% (M1) sebagai kontrol, perlakuan kedua 10% (M2), perlakuan ketiga 20% (M3), dan perlakuan keempat 30% (M4) penambahan ampas tahu. Parameter yang diamati meliputi kualitas fisik yaitu warna, bau, suhu, pH dan tekstur pupuk, kualitas kimia terdiri dari N total, P total, K total, kadar air,kadar abu, C-organik, C/N rasio. Kualitas biologi terdiri dari jumlah daun sawi, berat panen sawi, dan panjang akar tanaman sawi. Data yang diperoleh diuji statistik dengan analisis variansi rancangan acak lengkap pola searah dan apabila menunjukkan perbedaan dilanjutkan dengan uji beda Duncan's Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa penambahan ampas tahu pada perlakuan M2 memberikan pengaruh beda nyata (P<0,05) dengan kontrol (M1) terhadap kadar air vermicompost. Perlakuan M3 dan M4 tidak memberikan pengaruh beda nyata dengan kontrol (M1) terhadap kualitas kimia vermicompost. Perlakuan M2, M3, dan M4 memberikan pengaruh berbeda nyata (P<0,05) dengan kontrol (M1) terhadap berat panen sawi. Perlakuan M4 memberikan pengaruh berbeda nyata (P<0,05) terhadap jumlah daun tanaman sawi. Kesimpulan penelitian ini, perlakuan terbaik adalah M2 (90% sludge biogas kotoran sapi dan 10% ampas tahu) karena pada kualitas biologi dapat meningkatkan berat panen sawi sebesar 33,32 gram.

This researchs purpose was to find out the effect tofu by product edition in vermicompost processing using biogas sludge as an basic material. This research consist of four treatment of different composition of tofu by product. The first treatment was using 0% (M1), the second treatment was 10% (M2), third treatment was 20% (M3), and the fourth was 30% (M4) of tofu by product. The parameter observed of physical qualities, chemical qualities, and biological qualities. Physical qualities were color, smell, temperature, pH and texture.Then, chemical qualities were the total of N (Nitrogen), P (Pospor), K (Calium), water degree, dust degree, C-Organic and also C/N Ratio.The last was biological qualities which consist of the amoung of mustards leaf, the weight of mustard, and long of the mustards root. The data were tested analysis variance of completely randomized design of one way anova, and the mean differences were analyzed with Duncan's Multiple Range Test (DMRT). The result of this research showed that adding the by product of tofu in M2 shows different effect (P<0.05) with control (M1) towards water degree of vermicompost. The differences of M3, and M4 treatment had no effect compared to M1 treatment toward chemical qualities of vermicompost.The differences of M2, M3, and M4 shows different effect (P<0.05) with control (M1) towards the weight of mustard it self (biological qualities of vermicompost). M4 treatment shows different effect (P<0,05) compered to control (M1) towards the amount of mustards leaf. The conclusion of this research was finest doses of tofu by product was M2 treatment (using 90% sludge biogas as its main compound and 10% by product of tofu) because can improve harvest weight of 33,32 gram.
