KAJIAN BEBERAPA SIFAT KIMIA TANAH PADA TANAH SAWAH DI BERBAGAI LOKASI DI KOTA PALEMBANG

Penelitian ini bertujuan untuk mengkaji beberapa sifat kimia tanah pada tanah sawah di berbagai lokasi di Kota Palembang.  Metode penelitian menggunakan metode survei.  Penelitian dilakukan di 10 Kecamatan di Kota Palembang yang memiliki petak sawah, pengambilan contoh tanah secara komposit pada 5 titik pengamatan di petak sawah pada kedalam 0-20 cm, kemudian dilakukan analisis di Laboratorium kimia, biologi dan kesuburan tanah UNSRI.  Dari hasil analisis yang telah dilakukan, diperoleh data sifat kimia tanah yaitu pH tanah, bahan organic, dan kapasistas tukar kation (KTK). Dari penelitian ini didapatkan hasil kandungan pH dalam tanah sawah di Kota Palembang tergolong dalam golongan masam - sangat masam , dimana nilai pH tanah pada lokasi penelitian paling tinggi ditemukan pada daerah Plaju yaitu 4,61, sedangkkan daerah Seberang Ulu I yaitu 3,69. Secara umum dengan tingkat kemasaman tersebut lokasi penelitian mempunyai tingkat kesuburan yang relatif rendah sehingga ketersediaan unsure hara bagi tanaman tergolong rendah.. kandungan bahan organik termasuk dalam golongan rendah – sedang. Kandungan  bahan organik  tertinggi ditemukan didaerah Ilir Barat II yaitu 4,54 %,  sedangkan   kandungan bahan Organik terendah ditemukan pada daerah Gandus yaitu 1,97 %. Bahan organik berkaitan erat dengan besarnya kandungan karbon organik di dalam tanah. Sedangkan  nilai kapasitas tukar kation (KTK) pada lokasi penelitian tergolong tinggi dengan kisaran nilai  25 – 40 me/g. Kapasitas tukar kation adalah jumlah kation yang dijerap dan dipertukarkan oleh tanah dan dinyatakan dalam satuan cmol(+)/kg. selain liat bahan organik merupakan   material yang dapat menyumbang KTK tanah, karena muatan negatif dari bahan organik dapat menarik kation yang bermuatan positif

Traditional Palembang Society Wisdom on Natural Resource Management for Food Security

Studies on managing natural resources are currently attracting high interest in research. This is driven by the desire to find solutions to the problems that arise in managing natural resources to meet the needs of human life. Population increase and growth have caused the use of natural resources to be increasingly depleted, even close to scarcity.
