Abstract

Limbah baglog atau media tanam jamur yang sudah tidak produktif jika tidak dikelola dengan baik akan menjadi sampah yang mengotori lingkungan. Baglog dengan komponen utama selulosa jika didegradasi oleh mikroorganisme dapat dijadikan kompos.Tujuan dari penelitian ini adalah untuk mengomposkan limbah baglog yang dapat digunakan sebagi media tanam. Pembuatan kompos dari limbah baglog dengan meremah baglog hingga tidak menggumpal, kemudian ditambahkan inokulan Bacillus cereus S1,Aspergillus sp., dan Candida G3.2. Kompos diinkubasi selama 21 hari dalam karung goni. Kompos yang telah matang ditandai dengan struktur bahan yang halus, berbau tanah, berwarna coklat kehitaman serta suhu tidak lebih dari awal. Bibit caisim usia 14 hari ditanam pada media tanam yang berasal dari kompos baglog. Kadar NPK kompos diukur sebelum aplikasi,setelah penanaman caisim dan sesudah panen . Pengamatan biomasa dilakukan sesudah panen. Analisa data menggunakan Analysis Of Variance (ANOVA)dengan signifikansi α= 5% jika terdapat beda nyata diuji dengan uji tukey. Hasil penelitian menunjukkan bahwa limbah baglog dapat dikomposkan oleh isolat Bacillus cereus S1,Aspergillus sp., dan Candida G3.2. Konsentrasi (NO3-) memenuhi standar baku mutu kompos sesuai SNI 19-7030-2004 yakni lebih dari 0,4, namun konsentrasi (PO43-) kurang dari 0,1 dan (K2O) kurang dari 0,2 belum memenuhi standart baku mutu kompos sesuai SNI.Media tanam kompos limbah baglog di semua perlakuan tidak berbeda nyata terhadap biomasa tanaman berdasarkan uji Tukey.

Baglog waste or mushroom growing media that are not productive if not managed properly will become waste that pollutes the environment. Baglog with the main component of cellulose if degraded by microorganisms can be used as compost. The purpose of this study is to compost baglog waste which can be used as a planting medium. Making compost from baglog waste with baglog weak until it does not clot, then adding inoculants Bacillus cereus S1, Aspergillus sp., And Candida G3.2. Compost is incubated for 21 days in gunny sacks. Ripe compost is characterized by a material structure that is smooth, smells of soil, blackish brown and no more than the initial temperature. Caisim seeds aged 7 days are planted in planting media derived from baglog compost. NPK levels of compost were measured before application, after planting caisim and after harvest. Observation of biomass is carried out after harvest. Data analysis using Analysis Of Variance (ANOVA) with a significance of α = 5% if there are significant differences tested by tukey test. The results showed that baglog waste can be composted by Bacillus cereus S1, Aspergillus sp., And Candida G3.2 isolates. Concentration (NO3-) meets compost quality standards according to SNI 19-7030-2004 which is more than 0.4, but concentrations (PO43-) of less than 0.1 and (K2O) less than 0.2 have not met compost quality standards according to SNI. Baglog compost growing media in all treatments were not significantly different from plant biomass based on the Tukey test.
