Abstract
Limbah baglog jamur tiram serta limbah buah-buahan dan sayuran berpotensi dimanfaatkan sebagai bahan baku pupuk organik cair karena masih mengandung bahan organik yang dapat didekomposisi melalui proses fermentasi. Penelitian ini bertujuan menganalisis perbandingan karakteristik MOL kubis dan kulit nanas (MOL Kukunas) dengan EM4, menganalisis kualitas pupuk organik cair berdasarkan variasi jenis dan dosis bioaktivator, serta menganalisis pengaruh pemberian pupuk organik cair terhadap pertumbuhan sawi pakcoy (Brassica rapa L.). Metode yang digunakan adalah deskriptif komparatif untuk membandingkan karakteristik bioaktivator dan kualitas pupuk organik cair, serta analisis statistik Welch ANOVA, Games-Howell, dan Kruskal-Wallis untuk pertumbuhan tanaman. Perlakuan pupuk organik cair terdiri atas tanpa bioaktivator, MOL Kukunas 200 mL, MOL Kukunas 300 mL, EM4 200 mL, dan EM4 300 mL. Pupuk organik cair difermentasi selama 21 hari dan diaplikasikan pada sawi pakcoy dengan dosis 10 mL/L air/polybag. Hasil penelitian menunjukkan MOL Kukunas dan EM4 memiliki pH dan suhu yang sama, yaitu 3,85 dan 26°C, tetapi berbeda pada warna, aroma, jenis, dan kepadatan mikroba. MOL Kukunas memiliki total kepadatan mikroba 3,3 × 105 CFU/mL, sedangkan EM4 sebesar 5,2 × 107 CFU/mL. Kualitas pupuk organik cair menunjukkan pH dan C-organik telah memenuhi standar mutu, sedangkan warna, nitrogen, fosfor, kalium, dan rasio C/N belum memenuhi standar. Kandungan hara makro tertinggi terdapat pada MOL Kukunas 300 mL sebesar 0,211%, sedangkan C-organik tertinggi pada MOL Kukunas 200 mL sebesar 19,994%. Pemberian pupuk organik cair berpengaruh nyata terhadap panjang tanaman berdasarkan uji Welch ANOVA, tetapi tidak berpengaruh nyata terhadap jumlah daun berdasarkan uji Kruskal-Wallis.
