Abstract

Indonesia merupakan negara yang rawan terhadap bencana gempa bumi karena terletak di wilayah cincin api Pasifik dengan aktivitas tektonik yang tinggi. Rendahnya tingkat kesiapsiagaan masyarakat dalam menghadapi bencana sering kali berdampak pada meningkatnya jumlah korban jiwa serta kerugian materiil. Penelitian ini bertujuan untuk menganalisis pengaruh simulasi triage bencana terhadap peningkatan kesiapsiagaan menghadapi gempa bumi di Desa Mangunkerta, Kecamatan Cugenang, Kabupaten Cianjur. Penelitian ini menggunakan desain kuasi-eksperimen dengan pendekatan two-group pretest-posttest design. Sebanyak 112 responden dipilih melalui teknik purposive sampling dan dibagi menjadi dua kelompok, yaitu kelompok intervensi (n = 56) dan kelompok kontrol (n = 56). Kriteria inklusi meliputi warga berusia 20–59 tahun yang berdomisili di Desa Mangunkerta. Kelompok intervensi diberikan simulasi triage bencana yang mencakup pelatihan penilaian prioritas korban, evakuasi dasar, dan koordinasi saat gempa bumi. Pengumpulan data dilakukan menggunakan kuesioner kesiapsiagaan yang mencakup dimensi pengetahuan, sikap, dan keterampilan. Analisis data menggunakan uji Wilcoxon untuk analisis intrakelompok dan Mann-Whitney untuk analisis antar kelompok. Hasil menunjukkan adanya peningkatan signifikan pada skor kesiapsiagaan dalam kelompok intervensi setelah pemberian simulasi (p < 0,05), sedangkan kelompok kontrol tidak menunjukkan perbedaan yang signifikan (p = 0,157). Terdapat perbedaan bermakna antara kedua kelompok setelah intervensi (p = 0,000). Simulasi triage bencana efektif dalam meningkatkan kesiapsiagaan masyarakat menghadapi gempa bumi, terutama dalam aspek pengetahuan, sikap, dan keterampilan.

Abstract

Knowledge about types of waste, waste sorting and its dangers is initial knowledge that must be possessed from an early age. This initial knowledge is part of environmental literacy. School is the most basic level of formal education in Indonesia. So indirectly, character formation about understanding waste management must be given at this level. The application of the principle of waste management, namely 3R, needs to be simplified into APiK (Take, Sort and Reduce). The purpose of implementing this method is to reduce the amount of unsorted waste in the school, thereby reducing the burden on waste officers and the accumulation of waste in the TPA. The training method in this service starts from Socialization, implementation of pre-test, screening of Apik method videos, Practice of making Waste Reduction Products and ending with a post-test. This service was carried out in an elementary education environment with 23 students participating. The entire series of activities have been carried out. Socialization and training were successfully implemented and there was an increase in student knowledge regarding waste management. They have learned how to make vermycompos, styrofoam bricks and Ecobricks. When the post-test was conducted, there was an increase to 81% of students who had understood waste management. This activity was carried out according to plan and succeeded in increasing student knowledge.

Abstract

Background: Indonesia’s position along the Pacific Ring of Fire exposes it to frequent seismic events. The recent magnitude 5.6 earthquake in Cianjur highlighted notable deficiencies in community preparedness, especially in areas such as knowledge, disaster education, and emergency response planning. Insufficient public awareness remains a major obstacle to effective disaster risk management. Objective: This study aimed to determine the impact of Virtual Reality (VR)-based education using the Simple Triage and Rapid Treatment (START) method on enhancing earthquake preparedness among community members. Methods: A quasi-experimental design with pre- and post-tests and a control group was employed. A total of 112 participants were selected via purposive sampling and divided into intervention and control groups. The intervention group engaged in VR simulations focused on the START triage process as part of their disaster education curriculum. Knowledge improvement was measured using the N-Gain Score to evaluate pre- and post-intervention changes. Results: The VR-based START triage training led to a 64.47% increase in participants’ knowledge, reflecting a moderate level of effectiveness. Compared to the control group, those in the intervention group showed significantly greater improvements in earthquake preparedness. Conclusion: Incorporating START triage into VR-based educational programs can substantially boost community members’ understanding of earthquake preparedness. This interactive and scalable method holds promise for enhancing public disaster education and fostering greater resilience in vulnerable populations.
