    Abstract
    Indonesia is an agricultural country that has many agricultural sectors to date. Agricultural cultivation in Indonesia is generally carried out in wetlands (rice fields) and dry land (gardens). The moisture content of paddy fields for paddy is usually very high and sometimes vehicles have to be operated on saturated and watery surfaces so that surface traffic is very difficult. This very soft soil is one of the biggest sources of the difficulty of mechanization in rice cultivation in rice fields. This study aims to obtain the value of soil resistance due to plate pressing in paddy fields. The results showed that the highest average soil penetration resistance was found at a depth of 20 cm with a plate surface area of 5 x 15 cm² and an angle of 90 ° of 70 kPa.The lowest average soil penetration resistance is found at a depth of 4 cm with a plate surface area of 5 x 5 cm² and an angle of 90 ° of 9 kPa.The soil texture in the study location was 27% dusty clay, 63% dust, and 15% clay).The highest ground water content was 43.07%.The highest bulk density is 0.90 g / cm³.
     
    Indonesia merupakan negara agraris yang memiliki banyak sektor pertanian hingga saat ini. Budidaya pertanian di Indonesia, umumnya dilakukan di lahan basah (lahan sawah) dan lahan kering (kebun).Kadar air lahan sawah untuk padi biasanya sangat tinggi dan terkadang kendaraan harus dioperasikan pada permukaan yang jenuh dan berair sehingga lalu lintas di permukaan sangat sulit.Tanah yang sangat lunak ini salah satu sumber terbesar dari sulitnya mekanisasi pada budidaya padi di sawah.Penelitian ini bertujuan untuk untuk memperoleh nilai tahanan tanah akibat penekanan plat di lahan sawah. Hasil penelitian menunjukkan rata-rata ketahanan penetrasi tanah tertinggi terdapat pada kedalaman 20 cm dengan luas permukaan plat 5 x 15cm² dan sudut 90° sebesar 70 kPa.Rata-rata ketahanan penetrasi tanah terendah terdapat pada kedalaman 4 cm dengan luas permukaan plat 5 x 5 cm² dan sudut 90° sebesar 9 kPa.Tekstur tanah pada lokasi penelitian adalah lempung berdebu pasir 27%, debu 63% , dan liat 15% ).Kadar air tanah tertinggi sebesar 43,07%.Bulk density tertinggi sebesar 0,90 g/cm³.
