Abstract

Problems that arise in forage supply are continuity of farm and it’s low productivity and limited soil water availability in dry season. This study aims to: 1) examine the role of AMF on the growth of some types of grass fodder by different levels of water stress on podzolic soil; and 2) understand the interaction between application of AMF in different water stress and the types of grass on growth of forage grasses. This research was conducted in plastic house of Field Laboratory of Assessment Institute for Agricultural Technology (BPTP) Aceh. Randomized block design (RAK) with 6 x 3 factorial for three replications was used. The first factor was application the AMF and water stress which consists of six levels, namely: C1 = Without AMF + water stress 60% of field capacity, C2 = Without AMF + water stress 80% of field capacity, C3 = Without AMF + without water stress (100 % of field capacity), C4 = AMF + water stress 60% of field capacity, C5 = AMF + water stress 80% of field capacity, C6 = AMF + without water stress (100% field capacity). The second factor was type of grass that consists of three levels, namely: R1 = Brachiaria decumbens, R2 = Brachiaria mutica, R3 = Cynodon plectostachyus. The parameters observed in this research were canopy fresh weight, root dry weight, leaf relative water content. Results showed AMF addition of water stress 60% of field capacity on Jantho podzolic soil increased the canopy fresh weight, root dry weight, and leaf relative water content. There were interaction effects between applications AMF at different water stresses and the types of grass against canopy fresh weight, root dry weight and leaf relative water content.

Abstract

Use of Guano and Fertilizer NPK to Improve Quality of Subsoil Media and Growth of Oil Palm SeedlingABSTRACT. Utilization of subsoil as a growing medium for the nursery is a challenge to replace the role of topsoil as media for oil palm nurseries mainly on main nursery. This research was aimed at studying the effects of organic Guano and inorganic NPK fertilizer on oil palm seedling growth on sub soil growing media. The experiment was conducted in a pot, arranged in a randomized complete block design (RCBD), factorial 4x3 with 3 replicates. There were two factors examined, 1) guano dose consisting of four levels, namely: 0 kg, 0.5 kg, 1.0 kg and 1.5 kg/polybags and 2) inorganic fertilizers NPK consisting of three levels, namely: 0, 15, and 30 g/polybags. The results showed that subsoil can be used for growing media with applications of fertilizer Guano and inorganic NPK fertilizer. Guano and NPK fertilizer affected several soil chemical properties, i.e. increase in soil pH, available total C and N and P, and cation exchange capacity (CEC) and affected growth of oil palm seedling at age 16 weeks after planting. The best combination for the best seedling growth was obtained at 1.5 kg Guano + 30 kg NPK

Abstract

This study aims to describe the condition of Tripa Peat Swamp Forest (TPSF) in the Province of Aceh Indonesia that has been converted from forest to oil palm plantation and mixed farms. The results showed that the degradation of the peat soil and the environment have occurred in the TPSF. Degradation of peat is characterized by the occurrence of changes in water holding capacity and changes in chemical and physical properties of soil. Environmental degradation is characterized by changes in groundwater levels and land subsidence. TPSF restoration efforts can be carried out in accordance with the directives of land use and land conservation and water management

Abstract

Plants need an ideal and healthy soil condition for their growth and a sufficient amount of soil macronutrients. To determine soil nutrients, several methods have been widely employed. Yet, most of them are based on solvent extraction, which is normally time-consuming, requires complicated sample preparation, and sometimes involves chemical materials. Thus, a novel, fast and simultaneous method is required as an alternative method used to predict soil macronutrients in a short period and without involving chemical materials. Near infrared spectroscopy (NIRS) can be considered for this need, since this method is fast, environmentally friendly, and non-destructive. Therefore, the main objective of this study is to apply an NIRS method to predict soil macronutrients (N, P, and K). The diffuse reflectance spectrum was acquired for soil samples in a wavelength range from 1000–2500 nm. Spectra data were corrected using a smoothing method whilst prediction models were developed using principal component regression (PCR) and partial least square regression (PLSR). Prediction accuracy and robustness were evaluated using these following statistical indicators: correlation coefficient (r), root mean square error (RMSEC) and residual predictive deviation (RPD). The results showed that NIRS was able to predict soil macronutrients simultaneously with a maximum correlation coefficient r = 0.97 for N prediction, r = 0.99 for P prediction, and r = 0.95 for K prediction. Thus, it may be concluded that an NIRS method is feasible to be applied as a novel, reliable and fast method to predict soil macronutrients (N, P, and K) simultaneously.

Abstract

Gold mining activities in Aceh Jaya District could lead to mercury contamination of the environment.This research was conducted to assess the status of mercury in Krueng Sabee river as impacted bygold processing waste dumped into the river in the District of Aceh Jaya. Water, sediment, andaquatic animal (biota) samples were taken at three locations along the river, i.e. downstream, half-waycenter, and upstream. Mercury concentrations in the samples were analyzed by using SNI 02-0086-2005 method for sediment and biota, and SNI 01-3554-2006 method for water, and measured usingAtomic Absorption Spectrophotometer (AAS). The results were then compared to water qualitystandards for mercury Indonesian Govermental Regulation (KepMenLH No.02/ MenKLH/ 2002, PP.No. 18 Tahun 1999, dan BPOM No. 3725/ B/ SK/ VII/ 1989). The results showed that mercury levelsin Krueng Sabee river at all locations sampled during wet and dry seasons were below that of thewater quality standards, whereas mercury concentrations in sediment and biota samples at allsampling locations in Krueng Sabee river were above the maximum contaminant level. High levelsof mercury in the aquatic environment may pose a health concern for the community living in thecontaminated area.
