Abstract

INTISARI Bencana longsor merupakan salah satu bencana yang sering terjadi di wilayah yang memiliki lereng yang terjal, khususnya di Indonesia. Salah satunya yaitu Kecamatan Ngargoyoso Kabupaten Karanganyar. Kecamatan ini terletak di barat lereng Gunung Lawu, yang menyebabkan Kecamatan ini rawan terhadap kerentanan longsor. Apalagi terdapat permukiman, lahan pertanian dan perkebunan masyarakat. Kondisi ini menimbulkan kerentanan longsor yang lebih tinggi, yang perlu menjadi perhatian. Tujuan dari penelitian ini adalah menganalisis kerentanan longsor di Kecamatan Ngargoyoso dan menganalisis kerentanan permukiman di Kecamatan Ngargoyoso. Metode yang digunakan dalam penelitian ini adalah metode survey, dengan teknik pengambilan sampel Cluster Random Sampling. Metode ini mengambil sampel pada setiap satuan lahan. Selain itu survey ini juga memperoleh data primer dan sekunder yang akan diniliai terkait dengan longsor untuk mendapatkan tingkat kerentanan fisik dan permukiman. Hasil penelitian menunjukkan kerentanan fisik memiliki kelas sedang dan kerentanan permukiman memiliki kelas sedang dan rendah. Kerentanan fisik tertinggi tersebar di satuan lahan V4-I-M-K dengan skor 37 dan terendah pada satuan lahan V4-I-M-PMK dan V4-I-M-SW dengan skor 25. Sedangkan kerentanan permukiman memiliki 2 kelas tingkat kerentanan yaitu sedang dan rendah. Kerentanan permukiman sedang tersebar di Desa Ngargoyoso, Kemuning, Segorogunung, Berjo dan Girimulyo, kerentanan rendah tersebar di Desa Nglegok, Jatirejo, dan Dukuh. Kata Kunci : Kerentanan, Permukiman, dan Longsor vii ABSTRACT Lanslide disaster is one of the disasters that often occur steep slopes areas, especially in Indonesia. One of them is Ngargoyoso sub-district Karangnyar Regency. This sub-district is located on the western flank of Lawu volcano, which is vulnerable to landslide occurrences. Moreover there are settlements, agricultural land and community plantations. This condition generates higher landslide vulnerability, which needs to be concern. The purposes of this research are to analyze the vulnerability of landslides in the Ngargoyoso sub-district, and to analyze the vulnerability of settlements in the Ngargoyoso sub-district. The method used in this research was survey method, with Cluster Random Sampling technique. This method took a sample in each land unit. Futhermore, this survey also obtained primary data and secondary data that will be scored related to landslides to get the physical settlements and vulnerability. The result show that physical vulnerability has moderate vulnerability calsses and settlements vulnerability has medium and low classes. The highest physical vulnerability is spread in the land unit V4-I-M-K with a score of 37 and the lowest in the land unit V4-I-M-PMK and V4-I-M-SW with score 25. While settlement vulnerabilities have 2 classes of vulnerability that is moderate and low.The medium vulnerability of settlements spread in the villages of Ngargoyoso, Kemuning, Segorogunung, Berjo, and Girimulyo, and low vulnerability is spread in the villages of Nglegok, Jatirejo, and Dukuh.
