Abstract

Change of Some Phisycial and Chemical Properties of Peat Soil of Jambo Aye- Aceh Utara and due to Depths of Dranage TreatmentABSTRACT. The objective of this research was to evaluate the change of physical and chemical properties of peat soil of Jambo Aye Aceh Utara due to the depth of drainage treatments. The research was set according to randomized completely design with three replication. Pipes of alluminium with length of 100 cm and diameter of 30 cm was used to set the depth of drainage treatments. The depth of drainage treatments were: no-drainage, 20 cm, 40 cm, and 60 cm. The results showed the dept of drainage on peat soil affected some of physical and chemical properties of peat soil. From the physical properties point of view, the deeper of drainage was conducted, the more subsidence occurred, otherwise the higher bulk density was occurred. From the chemical properties point of view, the drainage more than 20 cm decreased pH, N-total, P-available, K-exchangeable, and Base Saturated, otherwise increased C-organic, Cation Exchangeable Capacity, and Al-exchangeable. It was recommended to use the drainage depth of 20 cm for controlling the change of some physical and chemical properties of peat soil.

Abstract

Developing Prediction Method of Watershed for Main Rivers in AcehABSTRACT. The conversion of rural land to urban land usually increases erosion, discharge and volume of storm runoff in watershed. It also causes other problem that effect soil and water. An urban or urbanizing watershed is one in which impervious surface cover or will soon cover a considerable area. Impervious surface includes roads, side walk, parking lots and building. Natural flow paths in the watershed may be replaced or supplemented by paved gutters, storm sewers or other elements of artificial drainage. Hydrologic studies to determine runoff and peak discharge should ideally be base on long-term stationary stream flow records for the area, such records are seldom available for small drainage areas. Even were they are available, accurate statistical analysis of them is usually impossible because of the conversion of land to urban uses during period of record. It therefore is necessary to estimate peak discharge with hydrologic models based on measurable watershed characteristics. Only through understanding of these characteristic and experience in using these models can be make sound judgments on how to alter model parameter to reflect changing watershed conditions.

Abstract

Lhoknga Sub District was one of regions experiencing earthquake and tsunami disaster occurred on 26 December 2004. The aims of the research were to evaluate soil characteristics, to study land suitability and to propose recommendation of land use and rehabilitation of the tsunami affected agricultural area in Lhoknga Sub District. The result showed that soil textures were varied from very coarse at the area near to the coastline to rather fine at the area far from the coast. The soil structures of topsoil was generally plate and blocky, while that of subsoil was generally massive. The quality of irrigation water in was still suitable for crops, the pH of water was neutral and low in salinity (0,4 mS cm-1). The water quality of wells was high (good) and water quality of drainage and surface water was low (rather bad). Water quality of wells was good enough, indicated by low water salinity (0,26-0,78 mS cm-1) and  low of SAR value. The recommendations for land reclamation were (1) cleaning and repairing of irrigation and drainage channel  (2) leaching of salinity in topsoil from soil profile by flooding method (basin irrigation) or furrow irrigation,  (3) constructing the ditches for cultivation in managing the excess of salinity, (4) establishing ditches for paddy, and (5) removing the sediment above the topsoil.

Abstract

The purpose of the study was to determine the amount of rainfall interception on coffee plants, and obtain a relationship between rainfall and interception of coffee plant. The research was conducted in a coffee plantation in Kebet Village, Bebesen Sub-District, Central Aceh District. The experiment was carried out from February to March 2011. The method used in this research was a descriptive method, using direct measurements in the field. The samples of coffee plants were 4 years and 15 years old. The results showed that rainfall interception of 4 years-coffee-crop was 56.87% of the total rainfall of 82.50 mm  and  that of 15-year-old coffee plants was 72.12%, of total rainfall of 133.50 mm. The greater the rainfall was, the greater the interception would be, as well as the older age of the coffee plant was, the greater the percentage of interception was recorded. The average proportion of rainfall as the water passes (throughfall) was greater than the proportion of rainfall that becomes stream stems (stemflow), due to high density of leaves covering the stem. Relationship between rainfall and interception on coffee plants was a natural logarithm equation: (1) for 4 years coffee crop,  I = 3.440 ln (Pg) + 0.650 and R2 = 0.56; (2) for 15 years old coffee crop, I = 2.992 ln (Pg) + 2.371 and R2 = 0.69.

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

Keumala Dam is built on Krueng Baro River which is one of the strategic rivers in Aceh Province to irrigates the farmland and supplies drinking water for the community downstream. However, this river has a considerable issues due to its long path and passing through various geological formations, causing a high concentration of sediments in the river. Therefore, this study aimed to analyze the river hydrodynamics employing the HEC-RAS 5.0 software. The results of the study revealed that the flow capacity of sediment transport along the riverbed varies directly with the difference between the shear stress at the bottom sediment and the critical shear stress allowed for moving particles. Sediment transport occurred in all sediment samples from the upstream and downstream of Keumala Dam. The flow reduction due to the damming changed the channel and flow regime, while the decrease in water release reduced the floating and bottom sediment transport to the the downstream. The total sediment around the weir area at the normal discharge is 6,325,698.93 tons/year. Sedimentation around the weir is a severe problem as it can affect the function and performance of the weir and irrigation channel. Siltation due to sedimentation also closed the intake of Keumala PDAM. Thus, periodical dredging and transporting sediments from the bottom of the weir are necessary to overcome this problem. Dredging and transporting sediments will improve the Keumala weir performance to irrigates the Krueng Baro Irrigation Area. Thus, the discharge capacity of othe weir intake can be maintained to irrigate the farmland following the planned area.

Abstract

Abtstract - Rainfall-runoff modeling using tank model founded by Sugawara has been widely used in Asia. Many researchers use the tank model to predict water availability and flooding in a watershed. This paper describes the concept of rainfall-runoff modeling using tank model, discuss the problems and challenges the use of tank model, especially in Province of Aceh, Indonesia and how to improve the outcome of simulation of tank model. Many factors affect the rainfall-runoff phenomena of a wide range of watershed include: soil type, land use types, rainfall, morphometry, geology and geomorphology, caused the tank model usefull only for concerning watershed. It is necessary to adjust some parameters of tank model for other watershed by recalibrating the observed and simulated discharges. Rainfall runoff modeling using the tank model for a watershed scale is more reasonable focused on each sub-watershed by considering soil types, land use types and rainfall of the concerning watershed. Land use data can be enhanced by using landsat imagery or aerial photographs to support the validation the existing of land use type. Long term of observed discharges and rainfall data should be increased by set up the AWLR (Automatic Water Level Recorder) and rainfall stations for each of sub-watersheds. The reasonable tank model can be resulted not only by calibrating the observed and simulated discharges, but also by considering the observed and simulated infiltration for each soil and land use types of the concerning watershed.
