Abstract

An exceptionally strong earthquake with magnitude 9 on the Richter scale struck Aceh on December 26, 2004 at 07.59 local time, followed by a very big tsunami. The earthquake epicenter was located about 149 km south of Meulaboh City in the Indian Ocean. The tsunami waves travelled at a speed of + 500 km/hour. Entire strips along west coast of Meulaboh City was wiped clean from surface of the earth, many people were reported dead or missing in Meulaboh. Houses, office andbusiness buildings, roads, recreation areas, utilities, and other infrastructure elements were devastated, damaged, or made useless from the coastal line until 2km to the land area. The coastal planning for sustainable development of tsunamiin the area is needed for reducing the damages and saving the people life.

Abstract

Karanganyar District is a hilly area with steep slopes, rock constituent of young volcanic deposits of Lawu Volcano products, thick soil and relatively high rainfall, so it is potential for large landslides in this region. The landuse in the Karanganyar District including the Tengklik Village is generally dominated by rice fields, seasonal gardens and settlements. Plantation made up in areas with steep topography has great influence on erosion and landslides. Similarly, many settlements are built on a slope so that the area is very vulnerable to the threat of landslides. In the rainy season landslides are common. The potential hazard of landslidesoccurred in 14 sub districts in Karanganyar District. Large landslides have occurred in Karanganyar on December 26, 2007 which claimed the lives of 62 people, with the greatest victims were in the Ledoksari Village, Tawangmangu. The Tengklik Village has already experienced creep type landslides, which have destroyed settlements, roads, seasonalgardens and all existing infrastructure in the area. In order to do the proper handling and anticipation of a catastrophic landslide, a variety of technological applications landslides using geographic information system (GIS) was then carried out, to detect the configuration of 2D geoelectrical subsurface prone areas for landslide risk study and regional planning.

Abstract

Waduk merupakan badan yang air memilki multifungsi dalam menyokong kehidupan penduduk serta turut menciptakan keseimbangan ekologi, tata air dan lingkungan. Waduk Penjalin yang terletak di Kabupaten Brebes, Provinsi Jawa Tengah, mempunyai luas 4,77 km2 dengan volume maksimum rata-rata tahunan sebesar 7.942.500 m3 dan volume rata-rata minimum tahunan 2.610.000 m3. Waduk Penjalin merupakan bendungan tipe urugan, dengan ketinggian dari lembah terdalam 16 meter, lebar puncak mercu 4 meter dan panjang puncak mercu 850 meter. Kondisi tanggul sudah mengalami beberapa kali renovasi. Di bagian perbatasan dengan tanggul Waduk Penjalin terdapat permukiman dan infrastruktur yang sangat padat, dan mempunyai risiko tinggi apabila tanggul tersebut tersebut jebol. Sesuai amanat UU No 24 tahun 2007, maka perlu dilakukan kajian risiko bencana terkait dengan jebolnya tanggul waduk tersebut secara lebih mendalam. Kajian mengenai risiko yang menyangkut perpaduan antara bahaya dan kerentanan terkait jebolnya tanggul waduk menjadi hal yang sangat penting. Parameter yang dipakai dalam analisis kerentanan adalah tataguna lahan (tanaman tahunan, tanaman musiman, sawah, permukiman, lahan kosong dan badan air). Data hasil penilaian risiko tersebut dapat digunakan sebagai dasar pertimbangan perencanaan tata ruang berbasis kebencanaan serta pengurangan risiko bencana. Zona genangan akibat jebolnya tanggul Waduk Penjalin mengarah ke timur. Berdasarkan pada hasil analisis tingkatan risiko bencana jebolnya tanggul Waduk Penjalin yang dilakukan melalui analisis spasial, dibagi menjadi risiko tinggi, risiko sedang, risiko rendah dan daerah aman

Abstract

The west coast of Lampung area is included of high potential of disasters, both earthquake and tsunami. The Sumatera active fault zone and subduction zone are located in the area and as a source of earthquake hazards. The big earthquakes had struck in the in 1933 and 1994, causing great damages and manycasualties. Tectonic earthquake accompanied by tsunami causes sea water demolished main land kilometers away in the lowland topography of west coast of Lampung. The accuracy data of earthquake and tsunami disasters reduction are needed for disaster mitigation, land use management,regional planning and sustainable development in west coast of Lampung. All aspects of disaster risk reduction are well considered in order to minimize possible vulnerabilities and disaster risks throughout the society, activity, and place.
