Results obtained showed evidences of non-linear relationships between catch yields and environmental data. BG and ALB show largest CPUE values which occurred mainly in the area with SSTs of 26 – 27 °C and SSCs of 0.15 – 0.3mg/m3. CPUEs appear to be “randomly” dispersed and have a slight positive (negative) correlation with SSC (SST) i.e., 0.33 (−0.38) but not with GM values i.e., −0.02. The weak correlation between CPUE, SST, SSC and GM lead to assume that CPUEs might be linked to other influential parameters that are not assessed in the present study but are needed to give complete prediction of potential fishing ground areas, knowing that the length of observation period is less than 1 year.","PeriodicalId":310717,"journal":{"name":"2018 4th International Symposium on Geoinformatics (ISyG)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115452581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the value of tidal range obtained in each region, calculation estimates the amount of energy that can be produced. Calculation of tidal energy potential has been done using tidal barrage tool design. Based on this research, Southwest of Papua Island has the highest tidal range in Indonesia of more than 5 meters, while west of Sumatera Island (in the north) and southwest of Kalimantan Island have the lowest tidal range less of than 1 meter. Based on our analysis, Bagan Siapi-api (near Halang Island), Bagan Siapi-api (near Rupat Island), North Tembilahan, South Tembilahan, Gulf of Bintuni, South East of Papua (near Arafura Sea) and South of Papua (near Arafura Sea) are the potential locations for development of tidal energy with tidal barrage device. The prediction of electrical power that can be harnessed ranged from 60.45 MW to 3719.13 MW. The highest power that can be obtained is in the area of Gulf of Bintuni and the lowest power is in the area of Bagan Siapi-api (near Halang Island).

According to data from disaster management agency of Batu City, Badan Penanggulangan Bencana Daerah (BPBD), in a range time from 1th of January, 2016 to 31th of July, 2016, it was revealed that 39 landslides gained material loss up to 2,8 billion rupiahs. The early detection system of landslide disaster installed by BPBD of Batu City currently cannot work optimally so that the decision outputs produced by the system were inaccurate. In order to solve these problems, in this study, we propose a Real Time Landslide Monitoring System Based on 3D WebGIS and Embedded System, to anticipate the landslides disaster. A prototyping-based software model development was employed to build the software model. The initial step of this study was marked by DEM data extraction and processing spatial data such as digitizing, survey data extraction, manual digitation of the building, building 3D maps, and visualizing 3D Maps into WebGIS. We employed unit testing of white-box testing and sensor accuracy as a testing method. According to unit testing results, it was shown that all components of the program unit have the desired output results by mean all features can run properly. Whereas, the sensor accuracy test results show a high degree of accuracy. In another word, the data published by the system is valid.","PeriodicalId":310717,"journal":{"name":"2018 4th International Symposium on Geoinformatics (ISyG)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115980521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Especially data acquired using an optical sensor mounted on the UAV. The American Society of Photogrammetry and Remote Sensing (ASPRS) standards were used for the quality guidance. Fixed-wing type of UAV was employed with the mounted optical sensor. The final result of vertical elevation generated from the optical sensor then compared with the data of terrestrial laser scanner from two different spatial distribution of checkpoint (that is even and uneven) of two different locations (that is active and inactive) of high confidence area. The accuracy assessment found that the even spatial distribution and a higher number of checkpoints of active high confidence area lead to higher vertical elevation error, while the uneven distribution and lower number of checkpoints of inactive confidence area lead to lower vertical elevation error. This study proposed that for vertical accuracy assessment, the user need to find the inactive bare-earth confidence area for quality control of DTM derived from the mounted optical sensor on UAV.","PeriodicalId":310717,"journal":{"name":"2018 4th International Symposium on Geoinformatics (ISyG)","volume":"283 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116400198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The high number of fire incidents in Indonesia requires attention from the government so that any natural disasters such as forest fires can be resolved. These fire incidents can be analyzed since the data has already been obtained and recorded from satellite. Unfortunately, the data is too large to be analyzed as it was. Based on data obtained from the EOSDIS website, recorded as many as 289,256 fire spots occur in the region of Sumatra in the timeframe between 2001 and 2014. It needs an algorithm to segment the data or clusters the data so that large data can be processed into good information for the user. In this study, a comparative study of clustering algorithms between the K-Means and the Isodata was conducted. Both algorithms used in this study were assessed based on the quality of the clusters produced, which is calculated using Silhouette Coefficient (SC). The final result value of Silhouette Coefficient the K-Means method is 0.999997187, and the Isodata method is 0.999957161. so in this case, K-Means algorithm has a higher SC value compared to the Isodata algorithm in clustering the data of fire spots with a small SC value difference.","PeriodicalId":310717,"journal":{"name":"2018 4th International Symposium on Geoinformatics (ISyG)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116978391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

East Java is a province in Indonesia that often occurs forest fires. One of the forest areas that often occur forest fires in East Java Province is Tahura R. Soerjo area. Moreover, forest fires are one of the most challenging issues handled by Tahura R. Soerjo in managing forest areas. Moreover, until now the technology to overcome the problem of the forest is still very minimal.

Approach in watershed management is related to erosion threat that can be done by doing in handling and management of watershed. Management of soil conservation, erosion control and management of water catchment areas can be presented in geospatial information that contains spatial information and quantitative data from information on soil erosion. In this study, the risk map model of erosion in Beringin watershed mainly based in expert’s knowledge (AHP) and the RUSLE model which is considered to be a contemporary simple and widely used approach of soil erosion assessment. The risk mapping resulted in high class threatening 1.309%, medium grade 48.183%, and 50.508% of the total area of Beringin Watershed.
