Abstract

This research aims to propose a method to study the effect of data availability indisaster-response study. This research focused on how to quantify the relationbetween data availability and actions taken by decision maker. The more specifictopic is represented as disaster response due to varying data availability usingSerious Game method in the Public Works Unit Surakarta. The serious gameprovide scenario to gather data about several issues. Digital elevation model,flood alert stage decision making, and damage prediction information wereneeded. This research also could promote as a complement the other method forcollecting data and decision-making training program for flood manager. Theresult of analysis has shown that there are differences of responses based on thedata availability. Better responses can be achieved by the improvement of dataavailability. It also proves that the number of correct decision was raised by theimprovement of data availability.

Abstract

This research is aimed to assess the flood hazard in part of Surakarta usinghydrodynamic modelling. Flo2D software is used to simulate the flood for 10, 25and 100 year return period. The modeling results include two flood parameters, i.ewater depth and flow velocity. A comparison was made in flood hazard mappingbetween single parameter and multi parameters. The multi parameters hazardmaps improve the reliability of the hazard class delineation. The impact assessmentis done in two point of view, human safety and property damage. The furtherimpact assessment is done by calculating the number of buildings affected by flood.

Abstract

Abstrak. Akuisisi data dengan menggunakan pesawat tanpa awak semakin sering dilakukan. Penelitian ini memodelkan data elevasi dari pengukuran lapangan dengan menggunakan pesawat tanpa awak. Tujuan dari penelitian ini :(1) untuk menguji kemampuan pesawat tanpa awak dalam mengakuisisi data elevasi, dan (2) untuk membandingkan data elevasi jika ditambahkan data point cloud dan data pengukuran batimetri. Metode pengolahan dengan menggunakan data point cloud dilakukan dengan pertama-tama mencocokkan titik kunci. Pencocokan titik kunci mengkaitkan seluruh hasil foto udara hingga membentuk satu kesatuan area yang telah difoto. Selanjutnya dilakukan penampalan titik ikat pada area yang telah terbentuk dari pencocokan titik kunci. Titik ikat berfungsi sebagai koreksi data pada saat pesawat tanpa awak melakukan pengambilan data. Foto udara yang telah dikoreksi kemudian diolah untuk mendapatkan data point cloud. Point cloud berguna sebagai data penyusun ortofoto dan data Digital Surface Model (DSM). Pengolahan data point cloud hingga menghasilkan DSM dilakukan dengan menggunakan software Pix4D dan Agisoft photoscan. Hasil yang diperoleh menunjukkan bahwa terjadi peningkatan kemampuan DSM ketika data pointcloud ditambahkan data titik ikat dan data pengukuran batimetri. Sehingga dapat disimpulkan bahwa akuisisi data menggunakan pesawat tanpa awak mampu menghasilkan data yang dapat dipercaya. Selain dapat dipercaya akuisisi data dengan pesawat tanpa awak lebih murah jika dibandingkan dengan akuisisi data dengan foto udara.Keywords:  digital surface model, pesawat tanpa awak, titik ikat Abstract. Data acquisition using unmanned aircraft is increasingly being done. This study models elevation data from field measurements using unmanned aircraft. The purpose of this study: (1) to test the ability of unmanned aircraft to acquire elevation data, and (2) to compare elevation data if added point cloud data and bathymetry measurement data. The processing method using point cloud data is done by first matching key points. Matching key points links all aerial photography results to forming a single unit area that has been photographed. Next, a tie point is carried out in the area formed from matching key points. Tie points function as data correction when unmanned aircraft take data. Corrected aerial photos are then processed to obtain point cloud data. Point cloud is useful as orthophoto compiler data and Digital Surface Model (DSM) data. Point cloud data processing to produce DSM is done using Pix4D and Agisoft photoscan software.The results obtained showed that there was an increase in DSM capabilities when point cloud data was added to the tie point data and bathymetry measurement data. So, it can be concluded that data acquisition using unmanned aircraft is able to produce reliable data. Besides being reliable, data acquisition with unmanned aircraft is cheaper compared to data acquisition with aerial photography.Keywords: unmanned aerial vehicle, ground c point, Digital surface modelDOI: http://dx.doi.org/10.7454/jglitrop.v3i2.59

Abstract

The magnitude of the risk due to a disaster depends on several factors, namely the hazard (natural hazard), vulnerability, and capacity. The earthquake that occurred in 2006 in Bantul District caused the death toll, damage to the building, and the victim who suffered severe injuries to become people with disability. The purpose of this study is to analyze the factors causing earthquake victims to be people with disability. Questionnaires were distributed to 130 respondents, using simple random sampling technique. Based on the result of the research, the factors causing difable daksa are (1) threats: all difable daksa live in earthquake prone areas, (2) vulnerability: house building made from material that easily collapsed, (3) capacity: have knowledge and means of disaster mitigation, (4) community behavior during earthquake disaster: people do not know how to safely handle earthquake disaster.Besarnya risiko akibat suatu bencana tergantung pada beberapa faktor, yaitu ancaman (natural hazard), kerentanan (vulnerability)dan kapasitas/ kemampuan(capacity). Gempa bumi yang terjadi tahun 2006 di Kabupaten Bantul menyebabkan korban meninggal dunia, kerusakan bangunan dan korban yang mengalami luka parah sehingga menjadi difable daksa. Tujuan penelitian adalah menganalisis faktor-faktor penyebab korban bencana gempa bumi menjadi difable daksa. Kuesioner di sebar kepada 130 responden, dengan teknik simple random sampling. Berdasarkan pada hasil penelitian faktor-faktor penyebab menjadi difable daksa adalah (1) ancaman: semua difable daksa tinggal pada daerah rawan bencana gempa bumi, (2) kerentanan: bangunan rumah terbuat dari material yang mudah roboh, (3) kapasitas/ kemampuan: tidak mempunyai pengetahuan dan sarana mitigasi bencana, (4) perilaku masyarakat ketika terjadi bencana gempa bumi: masyarakat tidak mengetahui bagaimana cara aman menghadapi bencana gempa bumi.Key Word: Earthquake, Difabel, Capability and Ri
