Saphira, Halyta Mega (2019) Evaluasi WHC (Water Holding Capacity) Profil Tanah di Kebun Percobaan Kemiri Sunan, Kecamatan Kalipare, Kabupaten Malang. Sarjana thesis, Universitas Brawijaya.
Abstract
Evaluasi lahan merupakan suatu proses atau kegiatan penilaian penampilan lahan untuk tujuan khusus seperti halnya penilaian lahan kemiri sunan di suatu kebun percobaan. Kemiri sunan (Reutealis trisperma (Blanco) Airy Shaw) yang merupakan salah satu komoditas terbaik penghasil biodiesel ini, mampu menjadi pilihan komoditas potensial penunjang perekonomian daerah. Komoditas yang mulai dikembangkan ini tumbuh dan berkembang dengan bergantung pada ketersediaan air terutama pada lahan-lahan tadah hujan seperti halnya pada 2 blok lahan kemiri sunan di wilayah penelitian tersebut, yang memiliki karakteristik lahan dan usia tanam yang berbeda, serta pernah ditemui genangan air saat curah hujan yang tinggi berlangsung dalam kurun waktu yang lama. Melihat potensi ekonomi dan permasalahan di lahan pengembangan kemiri sunan, penelitian ini dilakukan dengan tujuan untuk mengevaluasi kondisi WHC (Water Holding Capacity) profil tanah . Pelaksanaan penelitian dilakukan pada 2 blok lahan kemiri sunan di kebun percobaan Balai Penelitian Tanaman Pemanis dan Serat (Balittas), Kalipare. Pemilihan blok lahan didasarkan pada adanya karakteristik lahan dan usia tanam yang berbeda, yakni usia 6 tahun 1 bulan dan 4 tahun 4 bulan. Kondisi WHC (Water Holding Capacity) aktual diperoleh melalui penentuan tekstur, pengamatan permeabilitas, pengukuran nilai pF 0; 2,5 dan 4,2, serta Berat Isi (BI) dan Berat Jenis (BJ) pada tiap horizon tanah yang didaptakan dengan mebuat 1 buah penampang profil tanah di tengah-tengah lahan kemiri sunan padatia blok lahan penelitian. Hasil yang diperoleh akan dikaitkan dengan potensi pengelolaan yang sesuai. WHC (Water Holding Capacity) pada blok lahan kemiri sunan usia 6 tahun 1 bulan memiliki nilai WHC (Water Holding Capacity) yang lebih tinggi dibandingkan dengan pada blok lahan kemiri sunan usia 4 tahun 4 bulan. Namun, kondisi WHC (Water Holding Capacity) kedua blok lahan tergolong dalam kriteria rendah (5-10% volume) hingga sangat rendah (<5% volume), sehingga perlu dilakukan pengelolaan tanah yang tepat. Saran pengelolaan yang dapat diterapkan adalah membuat lubang biopori yang mampu meningkatkan resapan air dalam tanah.
English Abstract
Land evaluation is a process or activity to evaluating the appearance of land for special purposes such as the assessment of Reutealis trisperma in an research land. Reutealis trisperma (Blanco) Airy Shaw, which is one of the best commodities producing biodiesel, is able to become a potential commodity choice to support the regional economy. Commodities that are being developed are growing and developing depending on the availability of water, especially on rainfed land as well as in 2 blocks of Reutealis trisperma in the study area, which have different land characteristics with planting age wich diffferents too, and have encountered puddles of water during bulk high rainfall lasts for a long time. Looking at the economic potential and problems in the land development, this study was conducted with the aim of evaluating the condition of the soil profile of the Water Holding Capacity. The research was carried out on 2 blocks land of Reutealis trisperma in experimental garden of Balai Penelitian Tanaman Pemanis dan Serat (Balittas), Kalipare. The selection of land blocks is based on the existence of different land characteristics and planting ages, namely age 6 years 1 month and 4 years 4 months. The actual condition of WHC (Water Holding Capacity) is obtained through texture determination, permeability observation, measurement of pF value 0; 2.5 and 4.2, as well as the bulk density and particle density at each soil horizon that was obtained by making 1 cross section of the soil profile in the middle of the Reutealis trisperma block of the research land. The results obtained will be associated with appropriate management potential. WHC (Water Holding Capacity) in the block of 6 year 1 month old Reutealis trisperma land has a higher WHC (Water Holding Capacity) compared to the 4 year and 4 month old Reutealis trisperma block. However, the conditions of the WHC (Water Holding Capacity) of the two land blocks are classified as low (5-10% volume) untill very low (<5% volume), so proper soil management is needed. The management advice that can be applied is to make biopores that can increase water absorption in the soil.
