Abstract

This research was conducted to study the relationship between soil moisture content and soil physical characteristics that affected the moisture.The soil samples were collected from 22 scattered sites of West Java and Central Java. Analysis of soil physical properties (texture, bulk density, particle density, total porosity and soil moisture retention) and soil chemical property (organic matter) was conducted at the laboratory of the Department of Soil Sciences, Faculty of Agriculture, Bogor Agricultural University. Analysis of simple linear regression was applied to know the correlation between soil moisture content and other basic soil physical properties.Availability of soil moisture (pF 4.20 – pF 2.54) significantly correlated with organic matter, total porosity, and micropores. The higher organic matter content, as well as total porosity and micro, pores the higher available soil moisture. Soil moisture of field capacity significantly correlated with clay content, sand content, micro and macropores. The higher clay content and micropores the higher soil moisture of field capacity. In the contrary, the higher macropores and sand content the lower the field capacity. Soil moisture of the wilting point significantly correlated with clay content and macropores. The higher clay content the higher the wilting point, while the higher macro pores the lower soil moisture of wilting point. Keywords: Available soil water, field capacity, organic matter, soil pores, wilting point

Abstract

The research was conducted in the Sub Watershed Cisangkuy of theUpper Citarum Watershed in the Bandung regency. Cisangkuy river playsimportant role in the water supply to the population of Bandung regency andBandung city. In the last ten years, the debit of the river was decreased at dryseason but increased at rainy season that causes of flood in some places. It isneeded to research the variability of hydroclimatology at the region. The monthlyrainfall and debit in range of 2001-2011 was processed using the coefficient ofvariation (CV), wavelets and moving average analysis. The result of thecoefficient of variation and wavelets analysis show the monthly rainfall of fourweather stations: Cileunca, Kertamanah, Cipanas and Ciherang have the CV of78%, 82%, 84%, 70% respectively and show the dominant oscillation around 8-16months. The debit of two hydrology stations: Pataruman and Kamasan have theCV of 97%, 86% respectively and show the dominant oscillation around 128months and 64 months. The analysis of moving average with the simple,exponential, adaptive methods show the increase of five yearly debit significantlyin the range of observed data which cause of the flood in the Kamasan Banjaranregion. The 8-16 months oscillation is associated with the apparent position of theSun between the Tropics of Cancer and Capricorn which cause regional variationsin the intensity of monsoon and it’s called annual oscillation. The 128 monthsoscillation of debit is associated with the ten to twelve (TTO) years oscillation inthe tropical tropospheric temperature. While 64 months oscillation is associatedwith the the tropical Pacific phenomena El Niño (warm condition) and La Niña(cold conditions) are the cause of 2-7 years oscillations which famous with ENSOcycle.Keywords: Watershed, Rainfall, Debit, Variability, Hidroclimatology, Wavelets,Moving Average, Oscillation

Abstract

One of the main problems with acidic soils is the availability of soil nutrients. In such soils, iron (Fe) and manganese (Mn) ions are highly present. This study evaluated the Fe and Mn fractions in the soil profiles of forests used for agroforestry and dryland agriculture in the upper Ciliwung watershed. The watershed is a zone of high rainfall washing. The evaluation was based on the results of analysis of soil samples taken at four soil horizons (Ao or Ap, A1 or A2, B1, and B2) for each type of land use. Research was conducted by survey and laboratory analysis. Fractionation of Fe and Mn employed sequential extraction methods with different compounds in each fraction. Fractionation was divided into exchangeable fractions (Exch), acid extractable (Acex), can be reduced (Red), oxidized (Oxs), and residual (Res). Results showed that Res Fe was (>23000.8 ppm or 76.3%) and Oxs Mn (>1642.9 ppm or 52.9%) dominated each type of land use, while the lowest fractions were Exch Fe (<12.2 ppm or 0.022%) and Exch Mn fraction (<97.2 ppm or 1.50%) in each type of land use.

Abstract

Kelapa sawit (Elais guineensis Jacq.) merupakan salah satu tanaman yang memerlukan air dalam jumlah yang banyak. Ketersediaan air merupakan salah satu faktor pembatas utama bagi produksi kelapa sawit. Pada musim kemarau kelapa sawit akan mengandalkan cadangan air bawah tanah untuk kebutuhan airnya. Hantaran hidrolik merupakan parameter sifat fisik tanah yang berperan dalam penambahan air bawah tanah. Tujuan dilakukannya penelitian ini adalah mengetahui karakteristik hantaran hidrolik jenuh pada berbagai jenis lokasi yang meliputi gawangan mati, piringan, dan jalan pikul pada perkebunan kelapa sawit PTPN VII Lampung. Karakteristik ini dapat dijadikan acuan pengelolaan lahan agar dapat meningkatkan cadangan air bawah tanah. Nilai hantaran hidrolik jenuh pada lokasi gawangan mati berkisar antara 2.9-30.4 cm jam-1 dengan kelas sedang sampai sangat cepat, pada lokasi piringan berkisar antara 2.5-13.4 cm jam-1 dengan kelas agak lambat sampai cepat, dan pada lokasi berupa jalan pikul nilai hantaran hidrolik jenuhnya berkisar antara 1.6-12.8 cm jam-1 yang berada pada kelas agak lambat sampai cepat. Tingginya hantaran hidrolik pada gawangan mati disebabkan terjaganya struktur tanah oleh tumpukan pelepah yang sudah mati. Hasil penelitian menunjukan bahwa aktifitas pemanenan yang intensif menurunkan nilai hantaran hidrolik jenuh tanah pada areal piringan dan jalan pikul tempat mengangkut hasil panen disebabkan peningkatan kepadatan tanah.

Abstract

Change in landuse caused by a population increase from 114,973 people in 2007 to 134,792 people in 2012 (14.70% increased) has influenced the hydrological characteristics of Way Betung watershed. The Soil and Water Assesment Tools (SWAT) hydrological model could predict the hydrological characteristics influenced by the change in landuse. The aims of this study were: 1) to assess the impact of landuse change on hydrological characteristics; and, 2) to recommend the best landuse of Way Betung Watershed.The SWAT model was applied to simulate the change of landuse in Way Betung watershed. The effects of landuse change on the hydrological characteristics of Way Betung Watershed in 2001, 2006, and 2010 showed  the water yield of 874.66, 1047.70, and 774.04 mm respectively. The coefficient of surface runoff (C) for those three years were 0.16, 0.31, and 0.23, whereas the coeficient of river regime were 30.65, 66.25, and 53.57 respectively. The application of agrotechnology on agricultural land and in line with the functions of forest area (scenario 4) gave the best response towards hydrological characteristics in the form of 709.69 mm of water yield with C being 0.14, whereas the coeficient of river regime value was 3.66.
