Abstract

The experimental study on hydrophobic and hydrophilic peat restoration from Central Kalimantan executed in labo­ ratory using Completely Randomize Design Factorial consist of two factors. The first factor was peat type that is hydrophobic and hydrophilic peat, and the second factor is type of surfactants, those are anionic, ionic and detergent condensation. The study aims at improving the nature of irreversible drying of  hydrophobic peat Kalimantan to be­ come productive again denoted by the depository efficiency fertilizer and water holding capacity. Results of research show the surfactants improve the depository efficiency of cation K+ and Mg2+ and can maintain soil moisture content of dry peat from 20 % becoming 150 %.ABSTRAKPercobaan restorasi gambut hidrofobik dan hidrofilik  dari Kalimantan Tengah dilaksanakan di laboratorium de­ ngan Rancangan Acak Lengkap Faktorial terdiri atas 2 faktor. Faktor I adalah jenis gambut yaitu gambut hidrofobik dan hidrofilik dan faktor kedua adalah jenis surfaktan yaitu anionik, inonik dan larutan deterjen. Tujuan penelitian adalah untuk memperbaiki sifat kering tidak balik (hidrofob) gambut agar dapat produktif lagi yang ditunjukkan de­ ngan efisiensi penyimpanan pupuk (kation) dan kapasitas memegang air (water holding capacity). Hasil penelitian menunjukkan surfaktan meningkatkan efisiensi penyimpanan kation K+ dan Mg2+ dan dapat mengembalikan kelengas­ an gambut yang kering dari 20 % menjadi 150 %.

Abstract

Farming in peatland can produce a commodity well if it follows the right planting calendar. Microclimate conditions in the peatland cannot yet be measured in real-time within a shorter time interval. Pelalawan, a region where most of its farmers use peatland for oil palm cultivation, need guidance on applying the best method of oil palm cultivation, which is  possible to improve. This study aims to apply a telemetric based (field monitoring system) real-time climatic data application to monitor the agricultural field (peatland). Climate data and weather – soil sensors were set up in Pelalawan village from August 18 to November 16, 2018. Besides, the advancement of planting calendar determination method is also done for peatland farming with a climatic water balance analysis. The change in peatland farming has been successfully observed and measured. The changes in the climatic environment can be observed continuously within a time interval of 30 minutes. Sun radiation data show a significant fluctuation shift from day to day. It also occurs for rainfall, temperature and humidity data. Climatic data fluctuation can be monitored directly and continuously with a Field Monitoring System (FMS) application. Water balance for paddy and corn is obtained based on Plant Water Need and Effective Rain. The recommended schedule according to water balance analysis (surplus and deficit) is paddy 1 – corn – paddy 2.
