Abstract

Abtstract - Rainfall-runoff model 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 model using tank model, discuss the problems and challenges in using of the 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 types, 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 parameters of the model. Rainfall runoff model 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 parameters, but also by considering the observed and simulated infiltration for each soil and land use types of the concerning watershed. Key words: rainfall-runoff model, tank model, infiltration, land use types, soil types, watershed

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.

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 ? Development of industrial forest plantation currently has a primary function to produce timber for the fulfillment of the pulp and paper industry raw matter. In times of growing trees plantations have the ability to absorb carbon dioxide gases (CO2) in the atmosphere throught the process of photosynthesis which builds biomass stands and produce oxygen gases (O2). The potency of forest stands biomass and build a model standing stock biomass using the Normalized Difference Vegetation Index (NDVI) value from Satellite Imagery was investigated. Types of crops grown in Forest Product Utilization Permit for Cultivated Forest Area in PT.Acehnusa Indrapuri are A.mangium and E.urophylla plantations with area approximately 15,500.59 ha. The results showed the biomass content at the lowest value 16.81 tons per hectare with the NDVI Value of 0.342 whereas the highest content of biomass amounted to 145.750 tons per hectare in NDVI value 0.813. The content of plant biomass of forest stands can be expected by NDVI values using the model equation Y = 250.32 X 2 -15.221X- 3.3623 with R2 of 97.27%

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 research aimed to analyse the climate type change and its effect on the weatland paddy production. The average precipation of area used a method of Thiessen Polygon. The temperature and air humidity used Dauglas HK.Lee’s classification. Meanwhile, Schmidth-Ferguson’ classification was used to observe the climate type change of the area and the climate change on the weatland paddy production was analysed through a regression multiple. The observation was conducted for 15 years in the first period (1983-1997) and for 15 years in the second period (1998-2012). The research results showed that the change of climate type in the area of Aceh Besar district had happened from the type A to the type B in the area of Saree and Kota Jantho subdistrict. Further, the climate change of type B to the type C also happened in Blang Bintang subdistrict. Saree had the average precipitation from 2.466 mm/year in the first period to 1.735 mm/year in the second period. Also, Blang Bintang subdistrict had the average precipitation from 3.857 mm/year to 1.393 mm/year, and Kota Jantho subdistrict had the precipitation from 4.431 mm/year to 1.917. The regression analysis showed that the climate did not have a clear influence on the weatland paddy productivity and the area the for live of wide harvested. Great Aceh District had implemented a development of agriculture for food plants which were not affected by the climate change structurally or non structurally. This can be seen from the fact that the Local Government had given a contribution to the society: such as giving new variety of plants in every planting season, organic fertilizer, drainage and reservoir building, opening a new weatland and agricultural extension workers. Although these contributions have not been implemented fully, they have given positive effect on the threat of food security in Great Aceh District for the last 30 years. This can be seen that the total of weatland paddy production in the last 15 years of the second period have got increased for 1.558.711 tons or 10.3 per cent and got decreased for 13.686 ha, so that the influence of climate change was not significant for two period examied. Abstrak: Penelitian ini bertujuan untuk menganalisis perubahan tipe iklim terhadap produksi padi sawah, rata-rata curah hujan wilayah menggunakan metode Poligon Thiessen, suhu dan kelembaban udara menggunakan penggolongan Dauglas HK. Lee. Sedangkan klasifikasi Schmidth-Ferguson digunakan untuk melihat perubahan tipe iklim wilayah, perubahan iklim terhadap produksi dilakukan analisis Regresi linier berganda. Pengamatan dilakukan pada periode 15 tahunan pertama (1983-1997) dan 15 periode 15 tahunan kedua (1998-2012). Hasil penelitian menunjukkan bahwa telah terjadi perubahan tipe iklim wilayah di Kabupaten Aceh Besar dari tipe A ke tipe B pada Kawasan Saree dan Kecamatan Kota Jantho. Selanjutnya perubahan tipe iklim B ke tipe C untuk Kecamatan Blang Bintang. Dengan rata-rata curah hujan Kawasan Saree 2.466 mm tahun-1 periode pertama menjadi 1.735 mm tahun-1 di periode kedua, Kecamatan Blang Bintang 3.857 mm/tahun menjadi 1.393 mm tahun dan Kecamatan Kota Jantho 4.431 mm tahun-1 menjadi 1.917 mm tahun-1. Analisis regresi menunjukkan bahwa perubahan iklim berpengaruh tidak nyata terhadap produktivitas padi sawah dan luas lahan gagal panen. Dikarenakan Kabupaten Aceh Besar telah menerapkan pembangunan pertanian tanaman pangan yang tahan terhadap perubahan iklim baik struktural maupun non struktural. Hal ini terlihat dari adanya bantuan Pemerintah daerah kepada masyarakat seperti: pemberian varietas-varietas baru setiap musim tanam, pupuk organik, pembagunan irigasi dan drainase, waduk, pembukaan lahan sawah baru serta tenaga penyuluh pertanian. Kendati demikian belum sepenuhnya terlaksanakan tetapi ini telah memberikan konstribusi terhadap ancaman ketahanan pangan di Kabupaten Aceh Besar selama 30 tahun terakhir yang terlihat dari jumlah produksi padi sawah 15 tahunan periode kedua terjadi peningkatan sebesar 1.558.711 ton atau 10.3 persen dan luas lahan gagal panen terjadi penurunan sebesar 13.686 ha, sehingga pengaruh perubahan iklim terabaikan selama dua periode tersebut.
