Alam, Nugraha (2019) Studi Kemampuan Infiltrasi Tanah Pada Sentra Tanaman Bawang Putih (Allium sativum L.) di Kecamatan Pujon, Kabupaten Malang. Sarjana thesis, Universitas Brawijaya.
Abstract
Budidaya Bawang Putih (Allium sativum L.) di luar musim (off season) memiliki pengairan yang kurang baik. Hal tersebut merupakan masalah utama yang dapat menghambat pertumbuhan dan produksi. Perbaikan faktor fisik tanah seperti penggemburan (porositas) dan permeabilitas tanah sangat diharapkan, karena akan berpengaruh secara langsung terhadap kelancaran fungsi infiltrasi. Peranan infiltrasi menjadikan penelitian tentang studi kemampuan infiltrasi pada lahan tanaman bawang putih sangat diperlukan. Data laju infiltrasi dapat dimanfaatkan untuk menduga kapan suatu limpasan permukaan (run-off) Penelitian ini dilakukan untuk mengukur tingkat infiltrasi tanah pada lahan Bawang Putih (Allium sativum. L) di Kecamatan Pujon, Kabupaten Malang. Selain itu, penelitian ini juga bertujuan untuk mengetahui karakteristik tanah yang mempengaruhi infiltrasi tanah dan pengaruhnya terhadap produktivitas pada lahan Bawang Putih (Allium sativum. L) di Kecamatan Pujon, Kabupaten Malang. Penelitian ini dilakukan pada bulan Oktober sampai dengan bulan Desember 2018 di Kecamatan Pujon, Kabupaten Malang. Penelitian dilaksanakan dengan metode survey yaitu menentukan titik pengamatan berupa SPL, pengamatan lapang dan pengambilan sampel tanah yang kemudian di lakukan analisis di Laboratorium Fisika Tanah Jurusan Tanah, Fakultas Pertanian, Universitas Brawijaya. Hasil pengamatan di lapang menunjukan bahwa terdapat 10 SPL yang terbentuk melalui jenis tanah (Inceptisols, Andisols, Alfisols), kemiringan (0-8%, 8-16%, 16-30%, dan >30%) dan juga landform yang didapatkan dari peta landform Kecamatan Pujon. Peneliti melakukan metode purposive sampling sehingga mendapatkan titik pengamatan sejumlah 5 SPL yang terbagi menjadi 2 titik pengamatan di setiap SPL. Penelitian lapang yang kemudian melalui tahap survey dan membandingkan dengan lahan yang memiliki produksi bawang putih di setiap SPL. Hasil penelitian menunjukkan bahwa (1) Hasil laju infiltrasi pada 5 SPL yang diamati tergolong ke dalam kelas infiltrasi cepat hingga sangat cepat yaitu diatas 12,5 cm/jam (2) Laju infiltrasi dipengaruhi oleh beberapa sifat fisik tanah. Hasil dari penelitian ini menunjukkan bahwa partikel liat memiliki peranan yang paling berpengaruh pada laju infiltrasi tanah dengan nilai korelasi negatif sejumlah -0,8032 (3) Berdasarkan hasil uji korelasi didapatkan hasil bahwa tidak ada hubungan secara langsung antara laju infiltrasi tanah dengan hasil produktivitas bawang putih (ton/ha).
English Abstract
Garlic cultivation (Allium sativum L.) in the off-season has poor watering. This is a serious problem that can inhibit growth and production of garlic. Improvement of soil physical factors such as fouling (porosity) and soil permeability is highly expected, because it will directly affect the smooth functioning of the infiltration. The role of infiltration makes the study of the study of the ability of infiltration in garlic crop fields very necessary. Infiltration rate data can be used to predict when a run-off will be carried out. This study was conducted to measure the level of soil infiltration in Garlic (Allium sativum. L) in Pujon District, Malang Regency. In addition, this study also aims to determine soil characteristics that affect soil infiltration and its effect on productivity on Garlic (Allium sativum. L) in Pujon District, Malang Regency. This research was conducted from October to December 2018 in Pujon District, Malang Regency. The research was conducted by survey method, which was to determine the observation points in the form of soil map units, field observations and soil sampling, which was then analyzed at the Soil Physics Laboratory at the Land Department, Faculty of Agriculture, Brawijaya University. Field observations showed that there were 10 SPL formed through soil types (Inceptisols, Andisols, Alfisols), slope (0-8%, 8-16%, 16-30%, and> 30%) and also landform obtained from map of Pujon District landform. The researcher conducted a purposive sampling method so that the observation points of 5 soil map units were divided into 2 observation points in each SPL. Field research then went through the survey stage and compared with the land that had garlic production in each soil map units. The results showed that (1) The results of infiltration rates at 5 soil map units observed belong to the fast to very fast infiltration class, which is above 12.5 cm / hour (2) Infiltration rates were influenced by several physical properties of the soil. The results of this study indicate that clay particles have the most influential role on the rate of infiltration of the soil with a negative correlation value of -0.8032 (3) Based on the results of the correlation test the results show that there was no direct relationship between the rate of soil infiltration and the yield of garlic productivity (tons / acre).
