Budidaya jamur tiram (Pleurotus ostreatus) bergantung pada media tanam homogen yang disebut baglog, yang terutama terdiri dari serbuk gergaji, sekam padi, dedak, kapur, dan air. Metode pencampuran manual tidak efisien, memakan waktu, dan menghasilkan campuran yang tidak seragam, sehingga mengurangi kualitas pertumbuhan miselium. Studi ini menyajikan modifikasi dan evaluasi kinerja mesin pencampur baglog yang awalnya dirancang oleh Teguh (2017) yang menunjukkan tumpahan material dari drum pencampur dan kapasitas keluaran material yang tidak memadai. Modifikasi tersebut melibatkan perancangan ulang perpanjangan tinggi drum pencampur menggunakan rangka batang sudut (40 mm × 40 mm), pemasangan lembaran seng galvanis, dan penambahan mekanisme pembukaan berengsel dengan baut pengunci untuk mencegah kebocoran material. Pengujian kinerja dilakukan menggunakan tiga rasio massa serbuk gergaji terhadap sekam padi: 5 kg:5 kg, 7,5 kg:7,5 kg, dan 10 kg:10 kg. Sampel sebanyak 100 g dikumpulkan dari tiga titik pengambilan sampel pada interval pencampuran 1 menit, 2 menit, dan 3 menit. Hasil penelitian menunjukkan rasio campuran rata-rata 60% serbuk gergaji dan 40% sekam padi per 100 g sampel, dengan kapasitas produksi 25 kg/detik menggunakan motor listrik 0,5 Hp pada 1430 rpm. Mesin yang dimodifikasi menunjukkan peningkatan kinerja penahanan dan homogenitas pencampuran yang konsisten di semua beban yang diuji. Temuan ini mendukung potensi otomatisasi lebih lanjut dari proses produksi baglog untuk memenuhi permintaan jamur tiram yang terus meningkat di Indonesia.
