Traktor roda 4 merupakan alat utama dalam pengolahan tanah yang memiliki peran penting sebagai sumber tenaga penggerak. Namun, penggunaan traktor dapat menyebabkan pemadatan tanah yang berlebihan dan berdampak negatif terhadap struktur tanah serta terganggunya kandungan mineral, bahan organik, air, dan udara di dalam tanah. Salah satu alternatif penanganan pemadatan tanah adalah penggunaan mulsa organik yang terbukti dapat memperbaiki sifat fisik, kimia, dan biologi tanah. Penelitian ini bertujuan untuk mengetahui pengaruh jenis mulsa organik terhadap pemadatan tanah enam bulan setelah perlintasan traktor roda 4. 
Penelitian dilaksanakan pada bulan September 2024 hingga Juli 2025 di lahan Unit Penyewaan Jasa Alsintan (UPJA) Sokaraja dan Laboratorium Terpadu 1 IAB Universitas Jenderal Soedirman. Percobaan menggunakan Rancangan Acak Lengkap (RAL) dengan empat perlakuan, yaitu tanpa mulsa (M0), mulsa jerami (MJ), mulsa sekam (MS), dan mulsa serasah daun bambu (Md), dengan lima kali ulangan pada tiap kedalaman tanah (0–10, 10–20, 20–30, 30–40, dan 40–50 cm), sehingga diperoleh total 100 sampel. Variabel yang diamati meliputi dry bulk density, porositas, kadar air tanah, dan konduktivitas hidrolik jenuh. Hasil penelitian menunjukkan bahwa pemberian mulsa organik mampu menurunkan nilai dry bulk density serta meningkatkan porositas, kadar air, dan konduktivitas hidrolik jenuh. Kedalaman tanah turut memengaruhi seluruh parameter yang diamati. Nilai konduktivitas hidrolik jenuh memiliki hubungan linier negatif dengan dry bulk density (R² = 0,6594) serta hubungan linier positif dengan porositas (R² = 0,6594) dan kadar air (R² = 0,3152). Hasil pengamatan 6 bulan menunjukkan kecenderungan peningkatan dry bulk density serta penurunan nilai porositas, kadar air, dan konduktivitas hidrolik jenuh dibandingkan data 0 bulan.

Abtrak (Bhs. Inggris)

The four-wheel tractor plays a crucial role in soil tillage, serving as a primary power source. However, its use often results in excessive soil compaction, which negatively affects soil structure and disrupts the balance of minerals, organic matter, water, and air within the soil. One alternative to mitigate soil compaction is the application of organic mulch, which has been proven to improve the physical, chemical, and biological properties of soil. This study aimed to investigate the effect of different types of organic mulch on soil compaction six months after four-wheel tractor traffic. 
The research was conducted from September 2024 to July 2025 at the Agricultural Machinery Service Unit (UPJA) Sokaraja and the Integrated Laboratory 1 IAB, Jenderal Soedirman University. The experiment was arranged in a Completely Randomized Design (CRD) with four treatments: no mulch (M0), straw mulch (MJ), rice husk mulch (MS), and bamboo leaf litter mulch (Md), with five replications at each soil depth (0–10, 10–20, 20–30, 30–40, and 40–50 cm), resulting in a total of 100 soil samples. Observed variables included dry bulk density, porosity, soil moisture content, and saturated hydraulic conductivity. The results showed that organic mulch application reduced dry bulk density and increased porosity, moisture content, and saturated hydraulic conductivity. Soil depth also significantly influenced all observed parameters. Saturated hydraulic conductivity had a negative linear relationship with dry bulk density (R² = 0.6594) and a positive linear relationship with both porosity (R² = 0.6594) and moisture content (R² = 0.3152). Data collected at 6 months indicated a trend of higher dry bulk density and lower porosity, moisture content, and saturated hydraulic conductivity compared to data collected at 0 months.
