Abstract

Indonesia merupakan negara yang rawan terhadap bencana alam seperti banjir, tanah longsor, gempabumi dan lain-lain, bahkan dapat dikatakan indonesia merupakan laboratorium bencana alam oleh orang asing, hal ini dikarenakan indonesia terletak pada daerah yang aktif tektonik dan vulkanik sebagai akibat pertemuan tiga lempeng tektonik, yaitu Lempeng India-Australia, Pasifik, dan Eurasia. peneliti berusaha untuk meminimalisir akibat bencana dengan menggunakan teknologi tepat guna. Salah satu teknologi berkembang saat ini adalah sistem informasi geografis (SIG).Sistem Informasi Geografis berbasis dekstop (dekstop mapping) akhir-akhir ini mempunyai peran penting dalam mitigasi bencana alam, tetapi Dekstopmapping memiliki pembatas terhadap pengguna, karena hanya bisa menggunakan berdasarkan menu yang ada dan tidak bisa mengembangkan sesuai dengan kebutuhan. Penelitian ini dilakukan untuk mengembangkan SIG berbasis web yang dapat digunakan untuk monitoring banjir di wilayah Daerah AliranSungai (DAS) Bengawan Solo hulu, menggunakan Java Applet, PHP dan My SQL Spasial. Pengembangan sistem dirancang dengan menggunakan model waterfall dengan langkah-langkah berikut: 1) system requirements, 2) software requirements, 3) analysis, 4) program design, 5) coding, 6) testing, dan 7)operations, didukung dengan referensi penelitian, observasi, dan diskusi ahli. Hasil penelitian menunjukkan bahwa dengan menggunakan Java Applet, My SQL Spasial dan PHP, aplikasi SIG web dapat memberikan informasi tentang kerawanan terjadinya banjir di wilayah DAS Bengawan Solo Hulu. Pengguna dapat memilih wilayah yang dikehendaki sehingga aplikasi ini dapat memberikan informasi tentang tingkat kerawanan banjir, kemiringan lereng, jenis tanah, penggunaan lahan dan jumlah rumah yang harus dievakuasi apabila terjadi banjir di wilayah DAS Bengawan Solo Hulu berdasarkan area kerentanan banjiryang dipilih. Aplikasi ini diharapkan dapat digunakan untuk monitoring banjir di Wilayah DAS Bengawan Solo dengan mengetahui daerah yang potensi terjadi banjir, dan jumlah rumah yang berada dalam wilayah satuan kerentanan banjir. Sistem ini menjadikan mayasarakat bisa mengetahui lebih awal daerah mana saja yang berpotensi terjadi banjir sehingga bisa meminimalkan kerugian.Kata kunci : SIG Web, Banjir, DAS Bengawan Solo Hulu

Abstract

The study was carried out in Ungaran. The goals of this study are to know and to evaluate the potential spring to add drinking water of Ungaran population. This study uses observation and secondary data analysis. The collected data are meteorology data, the water production of Municipal waterworks, the quality and the quantity of springs, the number of population and the customers. The result of the study shows that there are eight springs with the total debit 157 liter/ second or 6739 m3/ day. The Municipal Waterworks uses 65 liter/ second or 5616 m3/ day with the leaking rate 7% or 5222,88 m3/ day and the rest is used for irrigation. The quality of spring is qualified for drinking water requirement. The need of drinking water for per capita of the population is 136.7 liter/ capita/ day. In 2003 the prediction of the number of consumers is about 20.745 persons, so the total need of drinking water is predicted about 2835.8 m3/ day. The total need of drinking water added with the leak water is 3032.36 m3/ day. The Municipal Waterworks fulfils the need of drinking water for the population especially for the consumers of Municipal Waterworks. However, if the number of customers is accounted based on the number of the population in the pipe sope (­+ 48246 persons), the Municipal Waterworks will not fulfil the need of drinking water for population, therefore it needs to add volume production of drinking water.

Abstract

ABSTRACT The study was conducted in Klaten Regency at Wedi Sub Watershed, part of Dengkeng Watershed. The study aimed to: 1) study the interpretation accuracy of black and white Panchromatic Aerial Photograph scaling 1: 50.000 in identifying the soil factor, slope, landuse, vegetation density, and land conversation, related to the influences  toward  water  infiltration  condition  in  the  research  area;  2)  make  the zonation  of  infiltration  capability  and  water  infiltration  condition  based  on  land factors  the  result  of  aerial  photograph  interpretation;  and  3)  study  the  spatial distribution pattern of water infiltration condition in the research area and analyze to the distribution according to spatial. The research method used aerial photograph interpretation with supported by limited survey for field test, by sampling method was stratified sampling. The method of analysis applied spatial analysis by using Geographical Information System (GIS). The result of the study showed that: 1) the level of aerial photograph accuracy for  interpreting  determinate  factors  of  water  infiltration  in  the  research  area  is acceptable each with the accuracy level of: slope 89.47%; soil texture 82.14%; land use 90.16%; vegetation density 88.89%; and land conservation 80.88%. It mean that although the accuracy level achieved had not been included in very good category, the aerial photograph still can be used in this study; 2) the condition of water infiltration in the research area tended to be relative still good,  indicated by the of the land unit in status of ‘critical’ in the width no more than 25% (30.496 km2). The land unit in status of ‘begin to be rather critical’ in the width of 55.692 km2 or 50.97 %; while the remaining 3.154 km2 or 20.62% was in the status of ‘natural normal’ and 22.544 km2 or 20.62% had ‘good’ status; 3) In the research area, the space of land units with the condition of good infiltration had no spatial relevance to the space of land units and the great infiltration capability.
