Abstract
INTISARI Penelitian ini dilakukan di Desa Lencoh, Kecamatan Selo, Kabupaten Boyolali, Provinsi jawa tengah. Secara geografis daerah penelitian terletak pada 437784 – 438959 MT dan 9172711 – 9171836 MS dengan luas wilayah 149.62 Ha. Secara umum, daerah penelitian termasuk daerah rawan bencana longsor. Penelitian ini bertujuan untuk menentukan tingkat kerentanan gerakan massa tanah dan/ batuan untuk permukiman dan mengetahui dampak gerakan massa tanah terhadap permukiman. Metode yang digunakan adalah survey, pemetaan, dan Pengharkatan. Metode yang dilakukan meliputi kegiatan observasi, pengukuran ketebalan tanah, menentukan tekstur tanah, permeabilitas tanah, pengukuran kemiringan lereng, dan pengamatan pendiskripsian morfologi sesuai parameternya, seperti tingkat pelapukan batuan, kekuatan batuan dan penggunaan lahan. Tahap penelitian mencakup tahap persiapan, tahap kerja lapangan dan analisis data serta pengerjaan laporan. Data yang diperoleh berupa data – data primer yang didapatkan langsung dilapangan dan data – data sekunder di peroleh dari berbagai pustaka dan instansi – instansi terkait. Metode yang digunakan dalam menentukan satuan lahan daerah adalah Metode Tumpang Susun (overlay) peta. Berdasarkan hasil analisis dan evaluasi hasil penelitian menunjukkan: Kerntanan gerakan massa tanah daerah permukiman Lencoh mempunyai 2 (dua) zona kerentanan gerakan massa tanah dan/ batuan yang meliputi : (1). zona kerentanan gerakan massa tanah dan/ batuan kelas III (tiga) dengan kriteria menengah dengan luas 41,83 ha, (2). zona kerentanan gerakan massa tanah dan/ batuan kelas IV (empat) dengan kriteria tinggi dengan luas 107, 79 ha. Dampak gerakan massa tanah terhadap permukiman, sementara tidak ada korban jiwa, tetapi menimbulkan dampak kerugian harta atau benda pada salah satu rumah warga dukuh Wates. Kata kunci : Kerentanan, Gerakan Massa Tanah, Permukiman. ABSTRACT The study area is located at Lencoh village, Selo sub - district, Boyolali district, Central Java. Geographically the study area located in 437784 – 438959 MT and 9172711 – 9171836 MS South Latitude with the extensive area 149.62 Ha. Generally the study area are including in vulnerable landslide area. The purpose in this study is to determine the degree of vulnerability of land mass movement and to evaluate the existing residential with land suitability for residential class criteria. The methodology that used in this study is survey, mapping and scoring. The methodology pervades measuring and directly observation of the texture and soil thickness, permeability, slope, description of morphological parameters, such as weathering, strength of rocks and land use. The methodology has done in several stages that are preparation, work in the field, analysis data and reporting. Data obtained in the form of primary data available from the field and secondary data available from literature and related agency. To determine the land units, researcher use map overlay methodology. Based on the result of analysis and evaluation, researcher obtain the result there are two vunerability zone of soil mass movement, that is : (1.) Vulnerability zone of soil mass movement levels III (intermadiate criteria) with 41,83 Ha of extensive area, (2.) Vulnerability zone of soil mass movement levels IV (high criteria) with 107, 79 Ha extensive area, from the study area. The impact of mass movement against of settlement, as a while there were no fatality, but there is an impact of property losses on one house resident at Wates Village Key words: Vulnerability, Mass Movement, Settlement.
