Abstract

Tsunami risk monitoring and management planning have become mandatory for the management of Pacitan District due to the high tsunami risk in the region caused by being among the subduction zone of the major plates and an area of active megathrust and ocean floor expansion. Approach in this study used four dimensions of risk to develop a tsunami index value: physical, social, economic, and environmental. The enumeration exercise used secondary data and analysis and processing techniques using QGIS and Microsoft Excel software, with the specific aim of graphically presenting the studied areas of tsunami vulnerability and the vulnerability index score from the regions for editing purposes. The locations such as Pacitan, Pringkuku, and Tulakan sub-districts are relatively vulnerable and therefore need to be upgraded its underdeveloped areas. This is because of poor infrastructure, population congestion, and unwarranted socioeconomic circumstances leading to a high level of exposure. Where such risks exist there is the need for planning such vulnerable areas according to the level to minimize the high risk of tsunami vulnerability in Pacitan.

Abstract

Background: Pengelolaan keuangan di tingkat Rukun Tetangga (RT) masih banyak dilakukan secara manual, sehingga berpotensi menimbulkan kesalahan pencatatan, keterlambatan pembayaran, serta permasalahan transparansi dan privasi. Kegiatan pengabdian masyarakat ini bertujuan meningkatkan efektivitas dan akurasi pengelolaan kas di RT 02 RW 06 Perumahan Griya Serpong Asri, Kabupaten Tangerang, melalui penerapan sistem digital berbasis Microsoft Excel yang terintegrasi dengan WhatsApp Blast (SheetWA). Metode: pelaksanaan meliputi wawancara dengan pengurus RT, perancangan sistem, simulasi, implementasi, dan evaluasi. Sistem memungkinkan pengiriman notifikasi iuran kas secara personal melalui pesan WhatsApp otomatis berbasis data Excel. Hasil: Terjadi peningkatan efektivitas penagihan dibanding metode manual, dengan 54% warga memberikan respons positif, serta meningkatnya transparansi laporan keuangan dan terjaganya privasi warga. Kesimpulan: Kegiatan ini menunjukkan bahwa pemanfaatan teknologi sederhana dan mudah diadopsi mampu meningkatkan kualitas pengelolaan keuangan komunitas secara efisien dan akuntabel.

Abstract

The city of Sukabumi is an urban area that has a high level of vulnerability to various disasters, especially hydrometeorological disasters such as floods and landslides, which are influenced by high rainfall, topography, and land use. This study analyzes the level of disaster vulnerability in the city of Sukabumi through the integration of social, economic, physical, and environmental aspects using a quantitative SIG-based spatial approach. This region has a high risk of hydrometeorological disasters due to intense rainfall, hilly topography, and changes in land use. Official data from BPS and BIG were processed through normalization, weighting, and mapping to produce a composite index per subdistrict. The results of the study show that 86% of subdistricts are in the moderate vulnerability category, namely Gunung Puyuh (0.41), Cikole (0.49), Citamiang (0.36), Warudoyong (0.503), Baros (0.356), and Cibeureum (0.449). Only 14% of subdistricts are in the low category, namely Lembursitu (0.321). The subdistrict with the highest vulnerability level is Warudoyong (0.503), while the lowest is Lembursitu (0.321). These findings emphasize the need for integrated mitigation strategies, especially in areas with moderate vulnerability indices that dominate the entire city.

Abstract

Ekosistem mangrove memiliki peran penting dalam menjaga stabilitas wilayah pesisir, namun terus mengalami tekanan akibat faktor alami dan aktivitas manusia. Penelitian ini menganalisis dinamika perubahan tutupan mangrove di Delta Mahakam, Kabupaten Kutai Kartanegara, untuk periode 2015–2025 serta memprediksi kondisi hingga tahun 2030 menggunakan pendekatan penginderaan jauh dan pemodelan sistem dinamis. Data citra Landsat 8 OLI diolah melalui Google Earth Engine untuk menghasilkan peta mangrove tahunan yang diklasifikasikan menggunakan algoritma Random Forest. Uji akurasi dilakukan melalui matriks kebingungan, akurasi produsen/pengguna, dan koefisien kappa. Deret waktu luasan mangrove kemudian digunakan untuk menghitung laju regenerasi dan degenerasi tahunan yang dimasukkan ke dalam model stock–flow pada Powersim Studio. Hasil penelitian menunjukkan penurunan luasan mangrove pada 2015–2020 dan peningkatan pada 2025 dengan luas mencapai 51.071,37 ha. Hasil simulasi sistem dinamis memprediksi adanya pertumbuhan positif yang sangat moderat hingga tahun 2030 dengan proyeksi luas 51.153,14 ha. Temuan ini mengindikasikan bahwa meskipun tekanan antropogenik masih terjadi, proses regenerasi alami dan potensi rehabilitasi turut menjaga kestabilan ekosistem. Pendekatan terpadu ini memberikan gambaran komprehensif mengenai dinamika mangrove serta mendukung perencanaan pengelolaan pesisir berkelanjutan.

Abstract

This research on the development of picture storybook media aims to provide education as literacy material for elementary school students regarding earthquake disaster mitigation, especially in the Cilegon area, Banten, which is one of the earthquake-prone areas. This research aims to develop a picture storybook media entitled "I'm Not Afraid of the Earthquake!" and find out the feasibility of the picture storybook. The process of developing picture storybooks uses the Hannafin and Peck method with three processes, namely needs analysis, design, and development with each process going through an evaluation and revision process. Data collection was carried out using questionnaires. The type of data produced is in the form of quantitative data that is analyzed using assessment criteria guidelines to determine product quality. The validation results from experts stated that the product with an average percentage of 95% with a very decent category. The assessment of media experts obtained a score of 93% and the assessment of material experts obtained a score of 98% and the trial of student products obtained a score of 90% with the category. This development research can be concluded that picture storybook media is very feasible to use for elementary school students.

Abstract

This study aims to identify the level of vulnerability of Yogyakarta City to the eruption of Mount Merapi by looking at four main factors: social, economic, physical, and environmental. The method used is secondary data analysis obtained from literature review and previous research, as well as the calculation of the vulnerability index based on BNPB Regulation No. 2 of 2012. The results of the study show that almost all sub-districts in Yogyakarta have high social vulnerability, influenced by low levels of education, limited access to information, and a high number of vulnerable groups such as children, the elderly, and low-income communities. Physical vulnerability is also quite high due to inadequate infrastructure and lack of evacuation routes. In terms of economy, most sub-districts show low to moderate vulnerability, although some areas are still dependent on certain sectors. Environmental aspects show low vulnerability, but long-term threats such as ecosystem damage due to volcanic ash still need to be considered. This study recommends mitigation measures in the form of strengthening social capacity, improving infrastructure, and diversifying the economy.
