Abstract

The Semeru Volcano eruption on December 4, 2021 caused damage to social, economic and environmental aspects. The Rejali Watershed (DAS) is one of the areas severely affected due to the eruption. The eruption resulted in 51 deaths, 10,565 displaced people, 1,027 houses damaged, two connecting routes and 43 public facilities damaged. This study mapped the disaster risk areas due to the eruption of Semeru Volcano. This research used Laharz to analyze the lava flow hazard map and weighting for social, economic, physical, environmental, and capacity vulnerability parameters. The results showed that the risk level of Semeru Volcano eruption is divided into three classes: high,  medium, and low risk. The high-risk area is 8915.09 Ha (14 %), the medium-risk area is 2174.74 Ha (17 %), and the low-risk area is 1885.60 Ha (69%). The high and medium risks were located on the upper and middle slopes of the Rejali watershed because the upstream area experiences a narrowing of the river flow (bottleneck) due to direct borders with structural land. The Semeru Volcano disaster risk map results can be used as a reference in sustainable risk management efforts in the Rejali watershed to reduce the impact and damage caused by the eruption.

Abstract

Disaster awareness sangat penting dimiliki oleh siswa untuk mengurangi resiko bencana. Pada proses pembelajaran disaster awareness di sekolah pada umumnya masih belum optimal. Penelitian memiliki tujuan untuk mengukur pengaruh geoinformation web technology terhadap disaster awareness siswa sekolah dasar di sekitar Gunung Semeru. Penelitian ini merupakan penelitian quasy experiment menggunakan desain pretest posttest one group. Subjek pada penelitian terdiri dari 36 siswa kelas lima SDN Sumberwuluh 2. Pemilihan lokasi penelitian didasari karena merupakan salah satu sekolah dasar yang terdampak langsung erupsi Gunung Semeru. Penentuan subjek dilakukan dengan simple random sampling technique sesuai saran guru di sekolah. Pengumpulan data menggunakan tes. Uji hipotesis penelitian dilakukan dengan Mann Whitney melalui nilai sig. 0,05. Uji hipotesis memperoleh nilai sig. 0,000 0,05. Menunjukkan adanya pengaruh geoinformation web technology terhadap disaster awareness yang didukung dengan perolehan nilai posttest lebih tinggi daripada nilai pretest. Dapat disimpulkan bahwa geoinformation web technology berpengaruh terhadap disaster awareness siswa di sekolah dasar sekitar Gunung Semeru.

Abstract

The series of volcanic activities of Mount Raung triggered primary and secondary hazards in the area around the volcano. Kalibaru watershed is one of the areas prone to landslides due to secondary hazards of eruption activity in the direction of west and northwest part of this region. This study aims to optimize tourism by mapping landslide hazard using Spatial Multi-Criteria Evaluation (SMCE) around Mount Raung. This research used 46 points of landslide data through remote sensing, field observation. Ten landslide triggering factors, namely TPI (Topographic Position Index), TWI (Topographic Wetness Index), SPI (Stream Power Index), slope, distance to river, rainfall, geology, land use, distance to road, and soil type was used to map the landslide hazard. This study used ROC (Receiver Operating Characteristic) analysis to validate the landslide susceptibility mapping with an AUC (Area Under Curve) value of 0.93, which indicates that the mapping has a high accuracy value. The results showed that the landslide susceptibility is divided into three classes: high susceptible, moderate susceptible, and low susceptible. The high susceptible area covers 151.62 km2 (21%), the moderate susceptible area covers 407.99 km2 (56%), and the low susceptible area covers 166.79 km2 (23%). Based on the results of the mapping, tourism development in the area of Mount Raung is recommended in areas that are classified as medium and low landslide susceptibility.Keywords: Mount Raung, Landslides, SMCE, Tourism Development

Abstract

INCREASING THE CAPACITY OF PRIMARY SCHOOL STUDENTS INVOLCANO ERUPTION DISASTER PREPAREDNESS THROUGH DISASTERMITIGATION SIMULATION IN THE MOUNT SEMERU REGION Indonesia ialah salah satu negara yang rawan terhadap bencana erupsi gunung api. Salah satubencana erupsi gunung api yang yang terjadi adalah Gunung Api Semeru Tahun 2021 dan 2022di Kabupaten Lumajang. Dampak letusan Gunung Api Semeru mengakibatkan banyaknya korbanjiwa. Hal itu membuktikan bahwa kurangnya pemahaman masyarakat dalam menghadapiancaman dan risiko bencana gunung api. Dengan demikan pentingnya tindakan untukmeminimalisir dampak akibat bencana yang akan datang kedepannya. Dengan adanya kegiatanpengabdian kepada masyarakat yang dilakukan oleh tim pengabdian dari Universitas Negeri Malang dalam program penelitian dan pengabdian Desentralisasi Fakultas Ilmu Sosial sebagaisalah satu solusi untuk meningkatkan kapasitas masyarakat dalam mengurangi risiko bencanagunung api. Kegiatan pengabdian dilakukan dengan pembelajaran kebencanaan dan simulasimitigasi bencana gunung api yang dilaksanakan di Desa Sumbermujur Kabupaten Lumajangpada sekolah yang terdampak langsung erupsi Gunung Semeru yakni SDN Sumberwuluh 2.Kegiatan pembelajaran kebencanaan dan simulasi bertujuan untuk meningkatkan pengetahuankebencanaan dan pengetahuan simulasi bencana gunung api, serta meminimalisir dampakerupsi Gunung Api Semeru. Metode diakukan dengan 4 tahapan yakni observasi awal,sosialisasi, pelaksanan, dan evaluasi. Hasil menunjukkan bahwa pembelajaran kebencanaandan simulasi bencana perlu rutin dilakukan di sekolah guna memberikan pengetahuankebencanaan sejak dini untuk menghadapi ancaman bencana yang sewaktu waktu dapat terjadi.Dari kegiatan yang dilakukan peserta didik juga mendapatkan pengetahuan, keterampilan dalammelakukan langkah-langkah penyelamatan diri bila terjadi bencana gunung api di sekolah. Indonesia is one of the countries prone to volcanic eruptions. One of the volcanic eruptiondisasters that occurred was the Semeru Volcano in 2021 and 2022 in Lumajang Regency. Theimpact of the Semeru Volcano eruption resulted in many casualties. This proves that the lack ofunderstanding of the community in dealing with the threats and risks of volcanic disasters. Thus,the importance of action to minimize the impact of future disasters. The community serviceactivities carried out by the community service team from the State University of Malang in theDecentralized Research and Service Program of the Faculty of Social Sciences are one of thesolutions to increase community capacity in reducing the risk of volcanic disasters. Thecommunity service activities were carried out with disaster learning and volcano disastermitigation simulations carried out in Sumbermujur Village, Lumajang Regency at a school directlyaffected by the eruption of Mount Semeru, namely SDN Sumberwuluh 2. Disaster learningactivities and simulations aim to increase disaster knowledge and knowledge of volcano disastersimulations and minimize the impact of the eruption of the Semeru Volcano. The method is carriedout with four stages: initial observation, socialization, implementation, and evaluation. The resultsshow that disaster learning and disaster simulation need to be routinely carried out in schools toprovide early disaster knowledge to deal with the threat of disasters that can occur at any time.From the activities carried out, students also gain knowledge skills in carrying out self-rescuesteps in the event of a volcano disaster at school.
