| Judul Artikel | PENGARUH APLIKASI JENIS MULSA TERHADAP SIFAT FISIK TANAH PADA BUDIDAYA KUBIS BUNGA (Brassica oleracea var. botrytis L.) DI LAHAN MARGINAL |
| Abstrak (Bhs. Indonesia) | Kubis bunga merupakan sayuran dengan prospek tinggi dalam nilai ekonomi yang dibudidayakan di dataran tinggi (Fitriani, 2009). Namun kuantitas dan kualitas produksi kubis bunga masih rendah yang disebabkan beberapa faktor (Arpanto & Soenyoto, 2018). Salah satu peningkatan produksi kubis bunga dengan pemberian mulsa baik mulsa jerami maupun mulsa plastik hitam perak. Tujuan dari penelitian yakni mengetahui pengaruh aplikasi jenis mulsa terhadap sifat fisik tanah pada budidaya kubis bunga (Brassica oleracea var. botrythis L.) di lahan marginal dan mengklasifikasi hubungan antar variabel sifat fisik tanah yang diamati. Penelitian dilakukan di Dusun Bulusari, Desa Sirau, Kecamatan Kemranjen, Kabupaten Banyumas pada Juni hingga September 2024. Pengambilan sampel tanah tidak terganggu dilakukan menggunakan ring sampler berukuran 100 cm3 setiap 1 minggu sekali selama 5 minggu pengamatan yaitu 7, 14, 21, 28, dan 35 hari setelah tanam pada 3 kedalaman tanah yaitu, 0 – 10, 10 – 20, dan 20 – 30 cm. Pada masing-masing kedalaman dilakukan 3 kali pengulangan pengambilan sampel untuk setiap kombinasi perlakuan (P0M0, P1M0, P1M1, dan P1M2) dan diperoleh 180 sampel. Analisis data menggunakan ANOVA, DMRT 5%, Student T Test, dan Analisis Regresi. Hasil penelitian menunjukkan perlakuan mulsa jerasi berpengaruh terhadap kadar air tanah basis kering, dry bulk density, porositas tanah, dan permeabilitas tanah di lapisan tanah bagian atas. Perlakuan mulsa plastik hitam perak berpengaruh terhadap kadar air tanah basis kering, dry bulk density, porositas tanah, dan permeabilitas tanah di lapisan tanah bagian bawah. Berdasarkan hasil regresi yang dilakukan, dihasilkan beberapa hubungan antar variabel sifat fisik tanah yang diamati. Linier negatif antara dry bulk density dan permeabilitas tanah dengan nilai R2 sebesar 0,2080. Linier positif antara porositas tanah dan permeabilitas tanah dengan nilai R2 sebesar 0,2080. Linier positif antara kadar air tanah basis kering dan permeabilitas tanah dengan nilai R2 sebesar 0,1610. |
| Abtrak (Bhs. Inggris) | Cauliflower was a vegetable with high prospects in economic value that was cultivated in highland areas (Fitriani, 2009). However, the quantity and quality of cauliflower production were still low, caused by several factors (Arpanto & Soenyoto, 2018). One of the efforts to increase cauliflower production was the application of mulch, either straw mulch or silver–black plastic mulch. The objective of this study was to determine the effect of mulch type application on soil physical properties in cauliflower (Brassica oleracea var. botrytis L.) cultivation on marginal land and to classify the relationships among the observed soil physical property variables. The research was conducted in Bulusari Hamlet, Sirau Village, Kemranjen Sub-district, Banyumas Regency, from June to September 2024. Undisturbed soil sampling was carried out using a ring sampler with a volume of 100 cm³ once every week for 5 weeks of observation, namely at 7, 14, 21, 28, and 35 days after planting, at three soil depths: 0–10 cm, 10–20 cm, and 20–30 cm. At each depth, three replications of soil sampling were conducted for each treatment combination (P0M0, P1M0, P1M1, and P1M2), resulting in a total of 180 samples. Data were analyzed using ANOVA, DMRT at a 5% significance level, Student’s T-Test, and regression analysis. The results of the study showed that the straw mulch treatment affected soil water content on a dry weight basis, dry bulk density, soil porosity, and soil permeability in the upper soil layer. The silver–black plastic mulch treatment affected soil water content on a dry weight basis, dry bulk density, soil porosity, and soil permeability in the lower soil layer. Based on the regression analysis, several relationships among the observed soil physical property variables were obtained: a negative linear relationship between dry bulk density and soil permeability with an R² value of 0.2080; a positive linear relationship between soil porosity and soil permeability with an R² value of 0.2080; and a positive linear relationship between soil water content on a dry weight basis and soil permeability with an R² value of 0.1610. |
