Abstrak: Badan Nasional Penanggulangan Bencana (BNPB) menyebutkan bahwa telah terjadi bencana longsor di sepanjang bulan Desember 2014 terdapat 9 titik longsor dan pada 5 Februari 2018 kembali terjadi longsor yang terdapat di 22 titik yaitu di Desa Batulayang, Tugu Utara, Jogjoan dan Tugu Selatan. Secara topografi kontur tanah berada pada kemiringan yang curam, dengan intensitas curah hujan mencapai 575.1 mm/bulan sehingga dapat berpotensi longsor. Tujuan penelitian untuk mengidentifikasi kerawanan dan keakuratan titik lokasi longsor berdasarkan dua metode yang dikeluarkan oleh Direktorat Vulkanologi dan Mitigasi Bencana yaitu DVMBG 2004 dan DVMBG 2005. Penelitian ini menggunakan data penginderaan jauh dengan melakukan pembobotan terhadap parameter longsor. Kemudian memvalidasi data dengan titik kejadian longsor. Hasil analisis dengan DVMBG 2004 menunjukkan tahun 2014 dan 2018 klasifikasi rawan longsor mendominasi dengan persentase 82.54% dan 64.59%. Hasil analisis menggunakan DVMBG 2005 tahun 2014 dan 2018 klasifikasi rawan mendominasi potensi longsor dengan persentase 68.63% dan 84.61%. Pada model pendugaan longsor DVMBG 2004 terdapat 9 titik yang tidak tervalidasi. Sedangkan pada DVMBG 2005 seluruh titik kejadian tervalidasi sehingga model pendugaan longsor DVMBG 2005 sebagai metode yang di rekomendasi untuk pembuatan peta potensi kerawanan longsor. Kata kunci: DVMBG, keakuratan, longsor, titik lokasi, National Disaster Management Agency stated that there have been landslides throughout December 2014 there were 9 landslide points and on February 5 2018 another landslide occurred in 22 points, namely in Batulayang Village, North Tugu, Jogjoan and South Tugu. Topographically, the land contour is on a steep slope, with rainfall intensity reaching 575.1 mm/month. The purpose of this study is to identify the vulnerability and accuracy of landslide location points based on two methods issued by the Directorate of Volcanology and Disaster Mitigation, namely DVMBG 2004 and DVMBG 2005. This study uses remote sensing data by weighting landslide parameters. Then validate the data with the point of landslide occurrence. The results of the analysis with the 2004 DVMBG show that in 2014 and 2018 the landslide-prone classification dominated with a percentage of 82.54% and 64.59%, respectively. The results of the analysis using the 2005 DVMBG in 2014 and 2018 classification of hazard dominates the potential for landslides with a percentage of 68.63% and 84.61%, respectively. In the 2004 DVMBG landslide estimation model, there are 9 points that are not validated. Meanwhile, in the 2005 DVMBG all points of occurrence were validated. So the 2005 DVMBG landslide estimation model is the recommended method for making landslide hazard potential maps. Keywords: Accuracy, DVMBG, landslide, point location

Abstrak: Longsor dapat menyebabkan bencana yang menyebabkan kerugian material maupun immaterial. Risiko dan dampak bencana longsor dapat diminimalisir dengan berbagai upaya mitigasi bencana longsor. Salah satu upaya mitigasi bencana longsor adalah pembuatan peta wilayah rawan longsor. Peta wilayah rawan longsor berupa Peta Zona Kerentanan Gerakan Tanah (ZKGT) sudah tersedia dalam skala 1:100 000 yang diterbitkan oleh Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG). Peta ZKGT skala 1:100 000 belum cukup menggambarkan area rawan longsor untuk skala kecamatan, sehingga diperlukan peta skala lebih besar untuk skala kecamatan. Penelitian ini bertujuan memetakan wilayah rawan longsor di Kecamata Sukajaya menggunakan pendekatan klasifikasi Resiko Bencana Indonesia (RBI), Badan Nasional Penanggulangan Bencana (BNPB) 2016 yang dimodifikasi dengan menambahkan parameter tutupan lahan. Keandalan peta dievaluasi menggunakan data kejadian longsor di Kecamatan Sukajaya pada tahun 2020 dan membandingkannya dengan Peta ZKGT PVMBG. Hasil pemetaan area rawan longsor RBI BNPB – Modif menunjukkan 75,4% wilayah Kecamatan Sukajaya memiliki tingkat kerawanan tinggi terhadap longsor. Evaluasi keandalan peta membuktikan bahwa Peta Area Rawan Longsor RBI BNPB–Modif untuk Kecamatan Sukajaya lebih andal dibandingkan Peta ZKGT PVMBG., Landslides potentially lead in disasters that result in both material and immaterial damages. Reducing damages from landslides can be accomplished through a variety of mitigation measures, one of which is the development of a landslide-venerability areas map. The Center for Volcanology and Geological Hazard Mitigation (PVMBG) has issued a map showing landslide venerability areas in the form of a Land Movement Vulnerability Zone (ZKGT) Map, scale 1:100 000. The ZKGT map at that scale is less sufficient to describe landslide venerability areas at the dstrict scale. Therefore, a larger map scale is required. The purpose of this study is to map landslide venerability areas in Sukajaya District, Bogor Regency utilizing the Indonesian Disaster Risk Mapping (RBI) approach of National Disaster Management Agency's (BNPB) 2016, which has been modified to include land cover data. The map's reliability was determined by comparing it to landslide events in Sukajaya District in 2020 and the ZKGT PVMBG Map. The results of the Modified RBI-BNPB–mapping of landslide vulnerability areas indicate that 75.4 percent of the Sukajaya District area is highly vulnerable to landslides, and the Modified RBI BNPB Landslide Map is more reliable than the ZKGT PVMBG Map.

Abstrak: Egg is an animal origin food product which has high nutritional value especially protein. Cholesterol content of eggs is only found in egg yolk, on the other hand albumen does not countain cholesterol at all but high content of protein, so it can be used as a free cholesterol-protein sources. The application of albumen as egg instant drink effervescent tablet can be an alternative of protein source for people who need free-cholesterol diet. It can also become an egg product diversification.
