Abstract

This study aims to determine the effect of giving kayambang bokashi (Salvinia molesta) on the growth of oil palm seedlings on peat. The research was conducted at land of Analytical laboratory Palangkaraya University, from July to October 2011. This research used Completely Randomized Design (CRD) single factor consisting of four treatments are: 0 ; 0,5; 1,0; and 2,0 kg. Bokashi kayambang polibag-1). Each treatment was repeated 6 times to obtain 24 units of the experiment. The results showed that bokashi kayambang has effect on height increment, increment the number of stem leaves and wet and dry weight of oil palm seedlings. There is no significantly different on stem diameter increment, leaf area, root length and number of roots. Bokashi kayambang a dose of 2 kg. Polybag-1 provides a real impact and can improve the wet and dry weight of oil palm seedlings

Abstract

The irreversible drying indicated by the hydrophobic characteristic is one of the characteristics of peat which can be used to indicate the level of peatland degradation. Hydrophobic peat usually occurs as a result of fire or intensive drought which is mainly caused by peat land conversion. The objective of this research is to study the effect of land use on peat hydrophobicity, based on FTIR spectra and water penetration drop time. The result show that hydrophobicity characteristics of peat is influence by land use differences. The abandoned or scrub land has higher hydrophobic characteristic which indicated by slow water penetration time and the higher hydrophobic index based on the FTIR method, compared with rubber and palm oil plantation. Organic compounds that appear and cause peat to become hydrophobic include carboxyl, hydroxyl phenolic groups, and high lignin content.

Abstract

The research aims to determine the effect of leaching on N-total and C-organic on podzolic soils and acid sulphate soils. This research was conducted for 6 weeks from March until April 2020, housed in the Laboratory of the Department of Agriculture, Faculty of Agriculture, University of Palangka Raya. This research used Complete Random Design (CRD) single factor. There are 6 treatments namely P1 = NPK fertilizer = 0 kg.ha-1 on Podzolic Red Yellow (PRY); P2 = NPK fertilizer = 150 kg.ha-1 on Podzolic Red Yellow (PRY) ; P3 = NPK fertilizer = 300 kg.ha-1 on Podzolic Red Yellow (PRY); P4 = NPK fertilizer = 0 kg.ha-1 on Acid Sulphate Soils (ASS); P5 = NPK fertilizer = 150 kg.ha-1 on id Sulphate Soils (ASS); P6 = NPK fertilizer = 300 kg.ha-1 on Sulphate Soils (ASS);. Each treatment was repeated 3 times. The measured variable is the content of N-total, and C-organic in soil and water leaching. Data were analyzed with analysis of variance on the level of alpha = 0.05 and alpha = 0,01. If there is real effect in treatment, The result of HRD (Honest Real Different) level of alpha = 0.05. The results of research showed the higher dose of NPK fertilizer compound given cause increased content of N-total, and C-organic on a red-yellow podzolic soil and acid sulfate soil before leaching and after leaching. The dose of NPP fertilizer Compound that high will increase the content of N-total, and C-organic dissolved in water leaching red yellow podzolic soil and acid sulphate soils.
