Abstract

Estimation of Chlorophyll-a Concentration using Refined Neural Network (Case Study: Lake Kasumigaura) Chlorophyll-a has been became one of clinical in-water constituents to represent water quality. Many researchers have used neural network method to estimate chlorophyll-a concentration in the water body. However, a few number of water samples limits the use of neural network, meaning that those number is insufficient to train the neural network model and makes the result is not reliable. One of famous interpolation method, that is Inverse Distance Weighting (IDW), is utilized in this study to enrich water samples dataset over non-station points. The data from those non-station points would further be used to train the neural network model. After the training, the neural network method was refined by using the water samples over stations such that the accuracy in chlorophyll-a estimation was increased. MERIS images are used in this study. Based on statistical analysis, RMSE value before and after the refinement is decreased from 6,7872 mg m-3 to 6,5606 mg m-3.

Abstract

The Application of WorldView-2 Image for Bathymetry Mapping in Kemujan Island Karimunjawa National Park The development of remote sensing technology gives an opportunity to extract bathymetry information on the optically shallow water area. This was done by utilizing the reflectance of spectral bands with the ability to penetrate water body. The aim of this research is to map bathymetry of Kemujan Island using remote sensing empirical modeling.  Quickbird image was used in this study. It has four spectral bands namely blue, green, red and near infrared band. These bands were rationed and acquired 12 band ratios. In total, 120 samples were used to produce bathymetry model and 379 samples were used for validation. The models were created for up to the depth of 7 m.  The result showed that the model from band ratio of green and blue band produced the highest accuracy with R² of 0.632 and SE of 1.2 m. The result proved that blue band is the most effective band to be combined with other bands for band ratio input for bathymetry modeling.

Abstract

Spatial Analysis of SSS Distribution Using 8-OLI Landsat Imagery As a Guide In Mitigating of Marine Corrosion (Case Study: Kendari Bay Waters) Sea surface salinity (SSS) is the amount of dissolved salt in sea water expressed in psu. Besides being able to be measured directly on the field, SSS could also be extracted from satellite image data. This study objective is to explain how SSS is extracted from Landsat 8 data to determine the distribution of SSS in Kendari Bay waters. Furthermore, distribution and patterns are used as guidelines for mitigating corrosion due to seawater on coastal building materials. In this study, SSS was extracted using channel-ratios with wavelengths of 450-510 nm and 530-590 nm, for 5 years (2014-2018). The results show that in 2014-2018 the estimated-SSS was 8,583 psu, 8,612 psu, 8,627 psu, 8,273 psu, and 8,372 psu; respectively. In the open sea, the salinity range is generally in the range of 33-37 psu with elative constant value. River runoff and high rainfall are the main factors in low SSS waters in Kendari Bay.

Abstract

Relative Radiometric Normalization for Multi-sensors and Multi-temporal based on Pseudo-invariant Feature Extraction Technology developments promote the abundance availability of multi-temporal satellite imagery data. Otherwise, the utilization of such satellite data have not been implemented optimally due to several limitation requirements. The utilization of the multi-temporal satellite images for change detection is advantageous for modelling and predicting spatial changes in particular period of time. However, in the implementation, the radiometric correction on either multi-temporal or also multi-sensors is required. In this research, weighted regularized generalized canonical correlation analysis (WRGCCA) is proposed to select invariant features or pseudo-invariant features (PIFs) for multi-sensors and multi-temporal images. The method is the improvement of multivariate alteration detection (MAD) that adopts canonical correlation analysis (CCA) and its extension, generalized canonical correlation analysis (GCCA), to detect bitemporal and multi-temporal data respectively. However, each of the methods, CCA and GCCA, has the limitation on differentiating acceptable PIFs due to sensitive to spatial changes. Therefore, with the utilization of weighting and regularization functions to the algorithm, the proposed method WRGCCA with the aid of iterative reweighted multivariate alteration detection (IRMAD) can select reliable PIFs and yielding more accurate PIFs significantly to 10% - 50% determined from root mean square error (RMSE). The improved PIFs selection can be explained by qualitative and quantitative analysis based on the multi-temporal image normalization.

Abstract

Effects of Land Cover Changes on GHG Emissions in Fast-Growing Areas in Semarang City This article aims to convey the results of the calculation of greenhouse gas (GHG) emissions from land cover change factors. The method used is spatio-temporal with remote sensing supported by Support Vector Machine classification techniques from Deztsaka Tools. The results obtained were the most significant changes in land cover occurred in the forest land cover class which decreased by 1515.29 Ha (21%). Carbon reserves in fast-growing areas have decreased by 90,741.06 tons (68.58%) and 22% of the area has released GHG emissions in the amount of more than 1000 tons. This phenomenon requires serious attention because land cover change is very significant, so that control efforts through spatial planning policies are absolutely necessary.
