Abstract

The spatial model for irrigated paddy yield acreage and yield prediction use the Landsat-TM of remote sensing data which has been producted by LAPAN using the Vegetation Index (VI) as a single parameter. Verification of the model mentioned above has also been done for Java Island showing that the accuracy result is acceptable for the operational although there are some limitation of the model. The objective of this research is to develop a spatial model for the paddy yield acreage and the yield prediction using Landsat-TM data, based on another parameter i.e the single parameter of Leaf Area Index (LAI), or using both parameter of LAI and VI to improve the accuracy prediction, compared to the accuracy using the single parameter of VI. The spatial model based on the Leaf Area Index (LAI) reduces dynamic factor of the parameter which control the growth stage of the paddy in the field such as the soil moisture (level of water) and the weather condition such as the temperature and the moisture radition, pests and diseases. In this research phase, the profile of LAI against the paddy age based on the field measurement shows that the LAI value increases a long with the vegetative growth and reaches the peak value of 4,567 at the maximum vagatative index (8-9weeks after the planting time). Furthermore, the LAI value decreases a long with the generative growth. The LAI value at the maximum vegetative phase can be used to predict the paddy production. The relation between the LAI and the spectral bands combination of Landsat-TM can be obtained by using the Power Regression Model as follows: LAI=0,2219*(TM4/TM3)2,1005(R2=0,95) where LAI means the value Leaf of Area Index on the paddy object at the paddy field area, which represents the pixel in the image spatial distribution. While TM3 means the digital number (gray level value) of the pixel in the spectral band 3 of Landsat-TM image data which represent the paddy object at the paddy field area, and TM4 means the digital number of the pixel in the spectral band 4 of Landsat-TM image data, which represent the paddy object at the paddy field area. The research also shows the application example or the model or the algorithm whivh is obtained in this research by using Landsat-TM. The LAI spatial of the paddy field area in Kabupaten Subang/Sukamandi West Java can be produced.

Abstract

Study on the utilization of satellite data for precipitable water vapor over Java Island has been done. MODIS (Moderate Resolution Imaging Spectroradiometer)data of TERRA/AQUA satellite are used to estimate the precipitable water. As one of the dynamic atmospheric parameter, the precipitable water data is able to indicate the dryness or wetness of a certain region. Such data can be devired from MODIS data at the wavelength range of 0.865, 1.24, 0.905, 0.936, and 0.940 um. Verification of precipitable water from MODIS data is done by using radiosodle data at 2 climatology station in Java Island (Jakarta and Surabaya). The verification result illustrate that the standart deviation between MODIS precipitable water and radiosonde data for the period of August-October 2004, the standard deviation is ± 1.6 cmand the correlation coefficient is 0.88. In addition, It is found that the correlation between the MODIS precipitable water and the altitude is significantly polynomial model. Beside that, the precipitable water tends to decrease along with the increase of the altitude at 0-2000 m above the sea level. The precipitable water in West Java is higher than in East Java, both in dry season and in rainy season. This condition can explain why the climate in West Java more wet than in East Java. We hope this research can be useful for spatial weather information in large area in real time.

Abstract

This research aims to estimate the land moisture condition of the agricultural land, especially for paddy fields based on MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data with 250 m and 500 m spatial resolution and daily temporal resolution. An index called Land Moisture Index (LMI) is created from 1st principle component result of NDSI (Normalize Difference Soil Index), and NDVI (Normalize Difference Vegetation Index), NDWI (Normalize Difference Water Index). There is a high correlation between the LMI and the soil moisture (LM) for the agricultural land with the soil moisture then more 75%, as the increasing of LM is followed by the increasing of the LMI. Based on the above method, the land moisture can be derived spatially from the agricultural land, and especially on the paddy fields for drought prediction.

Abstract

Segara anakan and its surrounding which is located in Cilacap Regency Central of Java, is the study area for this research. This region, like other estuaries, has a unique ecosystem which is protected and surrounded by the mangrove forest that can cause very dinamic development. In the upland, there are big rivers flow; Citanduy, Cibeureum, and Cimeneng. The main issue in this region is that the lagoon to become narrowing because of rapid sedimentation process. Landsat MSS, TM, and ETM of the years 1978, 1995, 1998, and 2003 are remote sensing data used in this research. An analysis in term of correlation between landuse/landcover change and sedimentation was carried out by looking at their change in the upper land especially along the rivers that have big contribution to the sedimentation in the lagoon. The result shows that there is high relation between landuse/lancover change in the upper land and sedimantation around the lagoon.
