Abstract
Atmospheric correction is very important process to determine of land and ocean surface properties measured from satellite data, especially optical remote sensing satellite system, because passive satellite instruments will always be contaminated by the influence of the atmosphere. The result of this processing is the surface reflectance (sr) product, and it is a necessary process when quantitatively monitoring environmental quality parameters from space. The goal of this study is to assessing of the spectral remote sensing reflectance satellite (Rrs
(λ) by the image correction for atmospheric effects (iCOR) tools on total suspended solid (TSS) concentration from the MultiSpectral Instrument (MSI) sensor on-board Sentinel-2 and the Operational Land Imager (OLI) sensor on-board Landsat-8. Involvement of 25 in-situ TSS stations in Kendari bay waters is to assess the results of iCOR-S2 and iCOR-L8. An assessment of the sr results reduced to Rrs
(λ) on the MSI and OLI data respectively, affected the value of R
2 where the highest value R
2 = 0.665 is shown on red band OLI data. Meanwhile, the assessment of three TSS algorithms models is built on Rrs
(λ), all of them showed mean relative error (MRE) < 30% and were considered capable of defining TSS concentrations in the study area.

Authors: Pratomo D G , Khomsin  , Putranto B F E 
Published: December 2019

Abstract
An Airborne LiDAR can be used to map the depth of the water. This system is called an Airborne LiDAR Bathymetry. In order to measure the water depth, an Airborne LiDAR is utilized with the green light sensor beside the near-infrared light sensor. However, water condition affects the capability of the green light penetration. The clarity of the water and the vegetation are some of the restriction for green light to penetrate the water especially in inland water areas. The research examined the penetration capability of the green light of the Airborne LiDAR Bathymetry in shallow water areas. A comparison of depth values derived from the LiDAR system and the direct measurements was performed to asses the penetration accuracy of the green light. The depth comparison is derived from eleven channels in the research area. The direct measurement was conducted by using a tape to measure the depth, and the RTK GNSS to measure channel’s dimension. A Secchi Disk also used to measure the turbidity of the water. The vertical reference for the depth is Earth Gravitational Model 2008 (EGM 2008). Based on the research, the depth difference between LiDAR Bathymetry and the direct measurement ranges from 0.02 m to 0.22 m. The vertical accuracy of the LiDAR Bathymetry is 0.239 m within 95% of confidence level.
Bathymetric mapping of shallow water using Landsat 8 and Sentinel 2A Satellite Data. Case Study: East Madura’s Waters

Abstract
Bathymetric mapping was used to map the sea floor. The accurate and recent sea floor data are needed by many human activities such as for water transportation routes and off-shore infrastructure constructions. General in-situ mapping using multi/single beam echo-sounder is time consuming, high cost and difficult access to a remote area. Bathymetric mapping on shallow water near coastal area also facing a challenge when the in-situ mapping is difficult to be performed for the reason of the access of survey-ship. In this research, we proposed a new technique to map the shallow sea floor (less than 80 m of depth) using optical remote sensing satellite data by exploiting the Landsat 8 and Sentinel 2A imageries. The bathymetric data estimated from these satellites then validated with in-situ measurement data collected in April and October, 2015. The range of absolute depth was 8.724 – 12.056 meter for Landsat 8 and 9.220 -11.149 meter for Sentinel 2. A promising result was obtained for Landsat 8 data with NMAE of 21.288% and wider range of estimated depth compared with obtained depth by Sentinel 2. Both samples point of remote sensing images failed to deal with water depth shallower than 8 m and deeper than 13 meters.

Abstract
Drought will affect almost every aspect of human life. The impact of drought hazards is often slow but certain, so that if not monitored continuously it will result in the loss of food due to crops and dead livestock, farmers losing their livelihoods and others. Lamongan regency is one of districts with drought level in very high risk class. At IRBI BNPB in 2011, Lamongan Regency is 2nd ranked of all regencies in Indonesia. By interpreting remote sensing data we will be obtained parameters such as ground surface temperature, vegetation density with EVI transformation, wetness index, brightness index, and land use. These parameters and accompanied by secondary data which is rainfall can be used to identify the drought potential in Lamongan because each parameter has properties that can be associated with its vulnerability to drought potential. Performed by weighting technique and overlay process on these parameters can produce the identified areas with very high drought potential which is 14.171 hectares or 0.009% of total area and dominated in Paciran Sub-District. And the identified areas with very low drought potential which is 20979.626 hectares with a percentage 13.222% of total area and dominated in Karangbinangun Sub-District, Kalitengah Sub-District, Turi Sub-District and Deket Sub-District.

Published: December 2019

Abstract
The use of historical and present spatial data in urban growth analysis has been considered as a fundamental prerequisite in urban geographical studies, future planning and implementation of city development policies. In the current study, a comparative analysis of urban growth based on city center and central business district (CBD) of Antananarivo, the capital city of Madagascar was carried out. Four temporal satellite images of 5 years interval were used to determine the pattern, the process and general conditions of expansion of the urban extents in different directions. Pearson’s chi-square test and Shannon’s entropy measure were used to evaluate the degree-of-freedom and degree of sprawl towards the analysis of urban growth. To combine the previously mentioned statistics, the degree of goodness was used. The comparative analysis shows that there are contradictive results in the derived statistical measures from both considered urban growth centers indicating different conditions of urban growth. Deeper analysis accompanied by the theory of Von Thünen on urban land use support that the CBD is the most appropriate center of growth for the application of the previously mentioned statistical measures for the case of Antananarivo city.

Published: December 2019

Abstract
The increasing population and inadequate planning resulted in informal settlements and poor social infrastructures in Kigali City. As response, the Kigali City authority adopted the Kigali City Master Plan (KCMP) to guide the urban development. However, no evaluations of the KCMP implementation has been carried out. This study assessed therefore the level of KCMP implementation and its impact on living conditions of urban dwellers in Nyarugenge District. We evaluated the KCMP implementation using Geographical Information System (GIS) overlay analysis, based on indicators of degree of conformity: accordance, unfulfillment and deviation. We assessed the impact of KCMP implementation using a paired sample t-test analysis to compare the availability/accessibility of urban quality of life indicators before and after the adoption of the KCMP. The results indicated that the level of KCMP implementation is low due to zoning categories and construction standards that are not affordable for low-income citizens. Nevertheless, this implementation has partly improved dwellers’ living conditions through the provision of some elements of urban quality of life. The KCMP should be revised thereby considering the affordability of its implementation by different stakeholders including low-income populations. Further researches should assess negative impacts of KCMP implementation on living conditions of urban dwellers.

Abstract
Unda river basin is one of the potential river basin in Bali Province of with a perennial river so that water availability is available every year. Even though it has a great potential, the river basin management is not optimal so that during the dry season there is still a lack of water. Water Evaluation and Planning (WEAP) is a model that can combine hydrological processes with management of water allocation in a catchment area. This model can evaluate the water availability in the Unda river basin. WEAP has a tool that is automatic delineation mode that can be used to automatically delineate catchment areas, land cover data and climate data based on satellite data which can make easier to modelling. The results of this study can be used as an evaluation in the water availability in the Unda River Basin so that the potential in the Unda River Basin can be optimal and sustainable.

Authors: Anjasmara I M , Mauradhia A , Susilo  
Published: December 2019

Abstract
Study by the National Centre for Earthquake Studies suggests the presence of two segments of Kendeng active fault, namely Surabaya fault and Waru fault in Surabaya. This study aims to investigate the surface deformation and earthquake potential in Surabaya that possibly related to the activities of those two faults. We use GPS campaigns data conducted in March 2017, September 2017, May 2018, and October 2018 and five GGPS CORS stations around Surabaya provided by the Indonesian Geospatial Information Agency. In total, 21 GPS stations data were processed to obtain horizontal and vertical displacement velocities in each station. The results showed almost all stations move toward southeast with the velocity rates range from 1.034 cm/yr to 5.674 cm/yr, except BM33 and SB07 that moves northeast with the velocity rates 4.065 cm/yr and 3.312 cm/yr respectively. For the vertical displacements, almost all stations subject to subsidence with the rates range from -0.190 cm/yr to -5.769 cm/yr. Only three stations subject to uplift namely BM23 with the rate of 0.234 cm/yr, BM24 with the rate of 2.844 cm/yr, and BM29 with the rate of 3.33 cm/yr. The strain analyses showed large shortenings in the area between two faults with the values up to 11.95 μstrain. From the results, we can conclude that the surrounding area of the two faults have different deformation patterns, and by confirming with geological data, we suggest that Surabaya has an earthquake potential due to the active faults.

Published: December 2019

Abstract
Land subsidence in urban area of Indonesia like Jakarta, Bandung, Semarang, Pekalongan and others is quite well known today. Base on the geodetic measurements (e.g. Leveling, GNSS and InSAR) we can identify rates per year and also magnitude in certain periods. Nevertheless the initial time of its occurrence, especially a part influenced by anthropogenic causes, in many cases still remains unclear due to data limitation. This is an interesting research question because the initial time is crucial for determining total magnitude, while this total magnitude is important information for assessing the impact of subsidence. For example to understand the occurrence of tidal inundation, widening area of flood, calculating cost of adaptation, water table inversion, etc. we need to know quite exact the total magnitude of anthropogenic subsidence from its first initiation. Luckily we have long data measurements of subsidence in Jakarta, long data observation of groundwater in several urban areas and times series of images satellite that can be used for determining the initial time of anthropogenic subsidence in urban area of Indonesia. This paper will highlight how these data set answering quite well the research question.

Published: December 2019

Abstract
The Ai Renung site is the first megalithic complex site on Sumbawa that has 8 sarcophagus objects and has been used as an ancient park by the NTB Provincial Cultural Heritage Preservation Hall. Unfortunately, until now it does not have a cultural heritage map that describes the location and condition of the site, so the presentation of spatial information that describes the location is not conveyed to tourists. In this study, an augmented reality application was made from a combination of 3D model visualization and orthophoto maps. Augmented reality application is implemented on an Android device. Application users can see the visualization of the 3D sarcophagus model virtually using an Android device when scanning one of the markers found on the Ai Renung Site Cultural Heritage Map. This study also analyzes 3D models and orthophoto. The results of the control point analysis on orthophoto, the RMSE value of 0.293 m was produced. Based on the CE90 test of the RMSE value, orthophoto can be used as a base map in making Cultural Heritage Zone Maps with a scale of 1: 1000 and entering into order class 3. As for forming a 3-dimensional model, most 3D model objects have RMSE values that are less than 0.5 m. So that it meets the Level of Detail 3 order criteria.

Abstract
Permanent surface water is defined as area of the Earth continental surface corresponding to an accumulation of water, showing slight variations in water levels, retaining most of their volumes over the year and that do not dry up. Bengawan Solo watershed, especially in the downstream area is situated in East Java, Indonesia and is recorded as the longest and the largest river on Java Island. Thus, this river becomes one of the biggest water resources in Java, Indonesia. As a water resources, it is important to identify spatial distribution of permanent surface water in Bengawan Solo River. Synthetic Aperture Radar (SAR) is an effective way to detect surface water over large areas. Sentinel-1 is a new available SAR and its spatial resolution and short temporal baselines have the potential to identify permanent surface water. Thus, we propose an identification of permanent surface water using Sentinel-1 data. The quantitative evaluation shows relevant results with overall accuracy of more than 97%, F-measure provides value 0.79, also very low False Positive Rate and commission error. There are also morphological and land use change detected in the area. These results are encouraging and the first step for monitoring Bengawan Solo River.
Analysis of ionosphere changes due to earthquakes (case study: Regency of Lombok and Donggala)
Authors: Cahyadi M N , Prasetyo M T A 
Published: December 2019

AbstractEarthquakes will form and propagate atmospheric waves, rayleigh waves, acoustic waves and gravity waves. When acoustic waves reach the ionosphere, this affects the ionospheric electron density that can be known from GNSS signals, this disorder is commonly called CID. Electromagnetic waves transmitted by GPS satellite signals that pass through the ionosphere will cause a delay in time, from this data can be used to detect the presence of ionospheric variations through TEC values. In this study an analysis of ionospheric changes due to the earthquake that occurred in Lombok Regency and Donggala Regency. The result of the analysis show that the value of ionospheric disturbance from 5 August – 28 September 2018 was around 0.19 TECU – 0.56 TECU.

Abstract
GNSS technology has been widely used in the field of surveys and mapping. According to Abidin this is because GNSS can be used regardless of time, is not affected by the topography of the survey area, and provides accuracy with a wide spectrum. GNSS technology also has several disadvantages, one of which is price. The tool used to implement GNSS technology has a high price, for example is the geodetic type which has prices ranging from hundreds of millions of rupiah. The last few years have found low-cost GNSS. which has a cheaper price. To find out the quality of low-cost GNSS a test was carried out. In this study a low-cost GN70 Oem Board was tested.
This study focuses on testing accuracy and precision. The method used for testing is RTK, and Static for data as a reference. RTK data acquisition uses the NTRIP method with CORS Surabaya as the base. There are 3 test locations in this study. The first is in BM01ITS or “bits”.
