Abstract

Runoff is one of flood and erosion causal factor in Indonesia. Runoff occurred when rainfall cannot be infiltrated and flowed on the ground surface. Cidanau watershed has quite high rainfall average (2573 mm/year) so it has high runoff potential. Zero Runoff System (ZROS) is one of water conservation way which can infiltrate runoff to the ground using permeation structures. ZROS’s successful parameter in order to decreasing runoff rate can be observed by the soil water content differences before and after ZROS application. Soil water content estimation was conducted by water balance model with and without runoff and then it is compared with soil water content from measuring. The simulation results indicated that soil water content in the research field before and after ZROS application is 0.476 and 0.569 m3/m3 respectively. The simulation is also conducted for past 10 years (2004-2013) and resulted higher soil water content if ZROS were applied. This results indicates that ZROS capable to decrease and permeate runoff to the ground and then increase soil water content level. Water balance model with and without runoff has coefficient of determination (R2) 0.606. It means that this model could simulate the soil water content differences before and after ZROS application valid relatively.

Abstract

Environmental biophysics of peatland has high fluctuating by time and its affected on soil CO2 emission. Therefore it is necessary to develop a system for monitoring the biophysical environment and CO2 emissions that can measure continuously to obtain accumulation annual carbon emissions more accurately. The objective of this research was to develop a monitoring system of the environmental biophysics of peatland and CO2 emissions from bare peatlands open. The system of measurement and monitoring of environmental biophysics that have been developed have been able to function properly which includes weather parameters and soil biophysical environment (temperature, soil moisture, and groundwater levels). Carbon emission was measured on an open peat land without vegetation amounting to 62.25 tonnes of CO2/ha/year. Carbon emissions have a positive relationship with soil temperature but has a negative relationship with soil moisture and rainfall.

Abstract

Climate change causes uncertainty in water availability. The change may include annual rainfall, evapotranspiration and the shift of rainy and dry seasons, thus, it affects hydrological response in the region. Water demand will increase over time with population, industrial and business growth but the water availability has not been ascertained to sustainably satisfy those needs.  Cidanau Watershed has wetland ecosystem so-called the Rawa Danau (Caldera), with an area of around 2,500 ha. This watershed receives average annual rainfall around 2,500 mm. Climate change especially the local climate in the region of Cidanau was analyzed to illustrate how the relationship with Cidanau river discharge. It is expected that climate change does not affect the water availability in the watershed. In this study, the analysis of local climate change and its impact on the availability of water resources on Cidanau Watershed was based on climate trends, water balance analysis, and estimation of  discharge of Cidanau Watershed. This research was carried out using climate data and discharge from 1996 until 2010. The results showed that climate variables have changed from 1996 to 2010. This change mainly occurred in temperature, annual rainfall, and evapotranspiration. Based on the analysis, the discharge of Cidanau Watershed will decrease due to changes in rainfall and evapotranspiration. The estimated minimum river discharge of Cidanau Watershed ranges from 0.5 to 1 m3/s until 2050.

Abstract

Artificial neural network (ANN) approach was used to model energy dissipation process into sensible heat and latent heat (evapotranspiration) fluxes. The ANN model has 5 inputs which are leaf temperature Tl, air temperature Ta, net radiation Rn, wind speed uc and actual vapor pressure ea. Adjustment of ANN was conducted using back propagation technique, employing measurement data of input and output parameters of the ANN. The estimation results using the adjusted ANN shows its capability in resembling the heat dissipation process by giving outputs of sensible and latent heat fluxes closed to its respective measurement values as the measured input values are given.  The ANN structure presented in this paper suits for modeling similar process over vegetated surfaces, but the adjusted parameters are unique. Therefore observation data set for each different vegetation and adjustment of ANN are required.

Abstract

Forecasting the occurrence of the onset of dry season and its length is important in determining the availability of water for irrigation, domestic and industrial uses. The length of dry season is used for reference in calculating water demand. Prediction of drought can be studied based on the rainfall patterns that have occurred. This is possible because there is a tendency that the rain will repeat a certain pattern at a certain time. The purpose of this study was to predict the onset of dry and rainy seasons as well as their length. Determination of the onset of dry season and its length was conducted using polynomial function of the cumulative amount of rain every single day based on the rain data. The research was conducted using rainfall data from Climate Station III in Serang from 1989 to 2010. The sum of daily rainfall could form a polynomial function. If the magnitude of daily rainfall in a certain period of time is less than the slope of the cumulative annual rainfall, then at that time the dry season is occurred. Determination of the dry season peak can be done by finding the maximum (extreme) point from the polynomial function by getting the second derivative which value is close or equal to zero. In average, the dry season occurred in Serang city started on the 132nd until 300th day. Deviation value for the onset of dry and rainy seasons were 23 and 38 days, respectively, with an average of length of 168 days. The average of R2 value for polynomial function was 0.9937.
