The Application of Landsat TM Data and SRTM Data for Detection Vulnerability Assessment of Flood in Bengawan Solo Watershed

Bengawan Solo watershed is one of watershed that has frequent floods. Due to high rainfall in the rainy season, the river can't accommodate the surface runoff and resulted flooding around the area. The high rainfall is not only causing flood in some areas upstream watershed, but also threaten the downstream areas in East Java province, especially Bojonegoro, Lamongan, Tuban and Gresik. Data of remote sensing and Geographic Information System (GIS) could detect assessment vulnerability of flooding. The research objective is to study flood vulnerability assessment in Bengawan Solo watershed using remote sensing data. The method is the combination of information from remote sensing data, i.e.. (1) to combine band 4 with band 7 Landsat TM in which the flood pixel value is ≤ 78; (2) to detect flow accumulation using SRTM data; and (3) to detect flooding areas at the altitude of 0-50 m. The result obtained from the study is the flood vulnerability in Bengawan Solo watershed including Sragen District (Masaran, Plupuh, Gesi, Sidoharjo Sub District); Ngawi (Widodaren, Kedungalar, Pitu SubDistrict); Tuban District (Rengel, Plumpang, Widang Sub District); Bojonegoro (Padangan, Malo, Kalitidu, Trucuk, Bojonegoro,Dander, Kanor, Baureno, Sumberejo Sub District); Lamongan (Laren, Solokuro, Karanggeneng, Kalitengah Sub District); Gresik Regency (Hamlet and Bungah Sub District)

Metode observasi dengan analisis deskriptif kualitatif terhadap faktor penurunan luasan ekosistem bakau dan sedimentasi. Data-data yang dikumpulkan yaitu energi fluks gelombang, peta karakteristik pantai dan peta sebaran bakau. Hasil dari pembobotan menunjukkan desa pantai yang termasuk kategori amat sangat diutamakan (A) adalah Gebang Kulon dan Gebang Ilir. Selanjutnya, pantai yang memiliki kategori sangat diutamakan tersebar merata hampir disetiap desa, kecuali desa Bendungan, Mundu dan Kalipasung yang kategori diutamakan (B), dan desa Tawang sari kategori kurang diutamakan (D). Kata Kunci: Identifikasi pesisir, ekosistem hutan bakau, kategori, Cirebon The study is to identify the coastal damage due to the conversion of coastal mangrove to fish ponds that is correlated with coastal changes in Cirebon regency.

Performance and Scalability Analysis of Node.js and PHP/Nginx Web Application

Node.js is an application framework that can be used to build network server and web application. Due to its maturity, Node.js should be tested in various aspects such as performance and scalability to build dynamic web application. For comparison, we use PHP/Nginx web development stack to build web application to compare and analyze Node.js web application performance and scalability. For research purpose, we build dummy applications based on Dijkstra Algorithm to calculate shortest path between nodes, in this case Trans Jogja shelters. Using load generator, we simulate concurrent user requests to test performance and scalability of Node.js and PHP/Nginx web application. The general results of this research showed that Node.js application had higher performance and scalability than PHP/Nginx application
