<![CDATA[The purpose of this study was to analyze the effectiveness (production, efficiency, satisfaction) of purun plant materials as a substitute for polybags in the nursery. This research was conducted in the nursery of the Faculty of Forestry, In November 2019 - February 2020 with the T test data analysis method and Boxplot comparison. The results of this study indicate that the characteristics of inorganic media bags are inorganic based, a mixture of various chemicals, and difficult to decompose. Meanwhile, organic media bags are purun-based and easy to decompose. The time needed to fill the inorganic media bag was 6.95 seconds longer than the organic media bag. The percentage of life for treatment A seedlings 92%, B treatment 92%, treatment C 96%, and treatment D 88%. The growth of Trembesi seeds is not significant. Inorganic media bag damage was only included in the 20% category (very difficult decompose), while the damage to organic media bags was in the category of 100% (easily biodegradable). The decomposition of the media bag in the inorganic media bag is very small or even absent because the number and length of roots that come out is tiny, while the organic media bag can decompose completely because of the number and length of wild rootsTujuan penelitian ini yaitu, menganalisis efektivitas (Produksi. efesiensi, Kepuasan) bahan tumbuhan purun sebagai pengganti polybag di persemaian. Penelitian ini dilakukan di persemaian Fakultas Kehutanan Universitas Lambung Mangkurat. Pada bulan November 2019- Februari 2020 dengan metode analisis data Uji T dan perbandingan Boxplot. Hasil penelitian ini menunjukkan bahwa karakteristik kantong media anorganik yaitu, berbahan dasar anorganik, campuran berbagai zat kimia, dan sulit terdekomposisi. Sedangkan kantong media organnik berbahan dasar purun dan mudah terdekomposisi Waktu yang diperlukan untuk mengisi kantong media anorganik lebih lama 6.95 detik dibandingkan kantong media organik. Persentase hidup bibit perlakuan A sebesar 92%, perakuan B 92%, perlakuan C 96%, dan perlakuan D 88%. Pertumbuhan bibit trembesi tidak ada yang signifikan. Kerusakan kantong media anorganik hanya masuk dalam kategori 20% atau sangat sulit terurai, sedangkan kerusakan kantong media organik sampai dalam kategori 100% atau sangat mudah terurai. Terurainya kantong media pada kantong media sangat kecil atau bahkan tidak ada karena jumlah dan panjang akar yang keluar sangat sedikit, sedangkan kantong media organik bisa terurai sempurna karena jumlah dan panjang akar yang keliar sangat banyak]]>
