Abstract

Abstract: Gampong Beureunut is a village with 323 population which located in District of , Aceh Besar. In the last 20 years, Gampong Beureunut has been repeatedly hit by flash floods in 1987, 2000 and the latest occured on January 2nd, 2013. The occurrence of flash floods is caused by the break of natural dam at Krueng Teungku groove that is located above the village and the estuary lies right in the Gampong Beureunut so the damage impact of flash floods is quite severe. Referring to the regulation of General Guidelines for Assessment of the Disaster Ratio issued by BNPB No. 2 of 2012, will assess the level of vulnerability of the community in Gampong Beureunut in term of tackling the threat of banjir bandang. There are four indicators to be taken in advance in term of determining the level, they are; social, economic, physical and environmental vulnerability. Based on the results of analysis data which the source information mostly obtained by direct survey to the location of the research found that the vulnerability level of community Gampong Beureunut against the threat of flash floods is medium. This shows that the people of Gampong Beureunut are vulnerable to the threat of flash floods so that some strategies are needed to reduce the vulnerability, among othersthe government should support the existence of gampong institutions that have been formed as disaster information centers, the need for extension, socialization and simulation, improvement of critical facilities and relocation of housing residents who are still in danger zone of flash floods.Abstrak: Gampong Beureunut adalah suatu gampong berpenduduk 323 jiwa yang terletak di Kecamatan Seulimum Kabupaten Aceh Besar. Dalam kurun waktu 20 tahun terakhir, Gampong Beureunut telah berulang kali dilanda banjir bandang yaitu tahun 1987, 2000 dan yang terakhir pada tanggal 2 Januari 2013. Terjadinya banjir bandang tersebut disebabkan karena jebolnya bendungan alam di alur Krueng Teungku yang terletak di atas permukiman penduduk dan bermuara tepat di Gampong Beureunut sehingga dampak kerusakan yang ditimbulkan cukup parah. Dengan berpedoman pada Perka BNPB No 2 Tahun 2012 tentang Pedoman Umum Pengkajian Resiko Bencana, pada penelitian ini akan ditinjau tingkat kerentanan masyarakat Gampong Beureunut terhadap ancaman banjir bandang. Untuk mendapatkan tingkat kerentanan ancaman banjir bandang, terdapat empat indikator yang harus ditentukan terlebih dahulu, yaitu kerentanan sosial, ekonomi, fisik dan lingkungan. Dari hasil analisis data yang sumbernya sebagian besar didapat dari survey langsung ke lokasi penelitian, didapat hasil bahwa tingkat kerentanan masyarakat gampong beureunut terhadap ancaman banjir bandang adalah sedang. Ini menunjukkan bahwa masyarakat Gampong Beureunut rentan terhadap ancaman banjir bandang sehingga diperlukan beberapa strategi untuk mengurangi kerentanan tersebut, antara lain pemerintah harus mendukung keberadaan lembaga gampong yang telah terbentuk sebagai pusat informasi bencana, perlunya dilakukan penyuluhan, sosialisasi dan simulasi, perbaikan fasilitas kritis dan relokasi perumahan penduduk yang masih berada pada zona bahaya banjir bandang.

Abstract

Representative Concentration Pathways (RCP) scenarios are based on assumptions about the future development of radiative forcing. There are 4 RCP scenarios, but only 2 RCP scenarios are used in this study, RCP 4.5 and RCP 8.5. The aims are to identify characteristics and percentage changes in extreme climate indices in the future. CMIP5 model data such as CCSM4, IPSL-CM5A-LR, IPSL-CM5A-MR, IPSL-CM5B-LR and NorESM1-M were used. The model data was downscaled using a statistical method, and bias correction was based on observational data from five BMKG stations in Aceh Province for the historical period (2001-2005). Subsequently, the observation data and bias-corrected model data for extreme climate events were identified based on the Expert Team on Climate Change Detection and Indices (ETCCDI). The extreme climate indices utilized in this study are consecutive rainy days (CWD), consecutive dry days (CDD), total annual rainfall (Prcptot), monthly maximum temperature (TXx), and monthly minimum temperature (TNn). The results show that the CDD, Prcptot, TXx and TNn climate indices tend to increase in 2021 – 2100 periods. Meanwhile, the CWD decreased. Based on the historical period, all extreme climate indices increased significantly in 2021 - 2100 except TXx, which decreased in 2021 – 2040.

Abstract

Ground movement is one of the most frequent disasters causing major damages in Indonesia. Unmanned Aerial Vehicle (UAV) has been widely used as a rapid observation method to obtain detailed characterization of ground movement. Often, active landslide area is difficult to access. This hinders close monitoring and observations of the ground movement. This study aims to demonstrate the use of UAV as tools for monitoring and observations on active ground movement area and to validate the results. For this purpose, the study was conducted at Gampong Lamkleng, Aceh Besar-Indonesia using spatio-temporal analysis by UAV photogrammetry. The UAV was chosen because it is easy to use, practical, and safe for landslide area that are relatively small and difficult to reach. Aerial photographs were processed using the Agisoft Metashape software in modeling and analyzed using Quantum GIS (QGIS) and ArcGis. The observation results show that the largest ground movement occurred in January 20 to 23, 2021 which was related to precipitation rates measured at a nearby rainfall station. The movement volume was 1,411.063 m3 and a rate of ground movement reaching 0.69 m/day due to heavy rain. The estimated value of losses is IDR 1,055,854,000. The UAV images analysis were compared to actual ground elevation measured using Real-Time Kinematic (RTK). The validation show that the accuracy based on comparison between photogrammetric and RTK measurement was at agreeable rate (99%). Otherwise, the accuracy performed on 19 check point using Root Mean Square Error analysis found that the accuracy was still very low. The low RMSE value is due to the georeferencing process using the Ground Control Point not being carried out.

Abstract

Earthquakes and tsunamis natural disasters have repeatedly occurred on the coast of Aceh province, which lies between the confluence of two plates. The tsunami deposits in this area can provide important information regarding the reconstruction of marine attacks by past earthquakes and tsunamis. In general, tsunami deposits can be identified based on their geological, sedimentological, paleontological, and geochemical characteristics. In our research work, spectrometry X-ray fluorescence (XRF) has been utilized to investigate the geochemical signatures of tsunami-affected soil samples in Aceh province at three tsunami-impacted areas, namely Aceh Besar regency, Banda Aceh City, and Aceh Barat regency. The sampling point is located about a kilometer from the coastal line. Our findings indicate that tsunami-affected soils in Aceh Province after 10 years struck by tsunami contain terrestrial markers such as Fe and Ti, carbonate markers (Mg, Ca), and heavy metals elements (Cr, Ni, Cu, Zn, and Sr). On the other hand, in our study, the concentration ratios of several elements such as Si/Ti and Ca/Ti seem most suitable as a chemical signature for differentiating environmental conditions such as the 2004 Indian Ocean tsunami event. It could be noticed that geochemical analysis by XRF can be applied to characterize the tsunami-affected soils in several coastal areas of Aceh province.

Abstract

The spread of the coronavirus has had a major impact on the education and tourism sectors, so lockdowns and travel restrictions have prohibited people from traveling. This lockdown policy calls for all activities to be carried out from home, such as work, travel and other outside activities. One of those affected is the Museum, where the Museum as one of the tourist destinations and also education places is affected because it cannot operate. As more and more people stay at home due to the coronavirus pandemic, the need for alternative ways of traveling becomes important. The rapid use of the internet during the pandemic, so that an alternative virtual tour as a substitute for traveling to a place directly becomes a solution. This study aims to evaluate the use of Tsunami Museum virtual tour uploaded in YouTube in 2020 as digital media during the pandemic. This research was conducted using a quantitative-qualitative method with a descriptive approach. Data were obtained from interviews, questionnaires, field observations, photo documentation of activities and literature studies. The results showed that the pandemic made Tsunami Museum manager carry out a digital transformation in educating the public. Virtual Tour uses the zoom application and utilizes social media to promote it. The results of the questionnaire distributed to the virtual tour participants of this museum showed above average of mean standar response from the respondents and were supported by the results of the committee's interview, mentioning that Virtual Tour can help disseminate information on the value of museums related to disaster even during Covid-19.

Abstract

Ek Leuntie Cave is a karst cave in Meunasah Lhok, Lhoong District, Aceh Besar Regency. This cave is very rare. It has 12 tsunami layers dating back 7500 years. These layers need to be preserved as a paleotsunami geopark in Aceh. However, there are many challenges to developing public facilities in karst areas, such as sinkholes and landslides. Therefore, this study aims to investigate the potential hazards in the area by using the Ground Penetrating Radar (GPR) method at 700 MHz and 250 MHz frequencies.  The GPR method is used because of its ability to image shallow subsurface structures with high resolution. The GPR method was used on 7 survey lines around Ek Leuntie Cave. The resulting radargrams are then processed using GPRPy software to clarify the reflection signal. GPR interpretation at 700 MHz and 250 MHz frequencies produces the same radargram at a very shallow depth, but the boundaries between layers are clearer at 700 MHz. Core data from multiple samples supports GPR interpretation. Based on the core data, the compact layer is located in the sandy soil layer, while the less compact layer is located in the old main road before the tsunami layer and in the bedrock. The less compact layer has potential hazards such as subsidence. The area is located in the west to south of the cave. Based on the GPR radargrams obtained, the investigation area is dominated by clay fill, sandy soil, clayey sand and bedrock. The results of the study are expected to be used as a reference for mitigation in the development of the Ek Leuntie Cave Geopark.

Abstract

Youth misconduct such as truancy, running away from home, smoking, and staying out late remains a recurring concern in Malaysia where public alarm has been amplified by viral social media cases. Legally, such adolescents fall under the category of “children beyond control” in the Child Act 2001. Between 2017 and 2023, the Department of Social Welfare recorded 1,534 cases nationwide, 40 of which were from the state of Terengganu. Failure to address such behaviour risks escalating into delinquency and crime, highlighting the need for early intervention. This study aims to identify the most prevalent forms of uncontrollable behaviour in Terengganu, examine legal procedures and rehabilitation orders imposed by the Court For Children, and propose improvements to strengthen child welfare protection. Using a descriptive socio-legal methodology, qualitative data were collected through semi-structured interviews with magistrates, welfare officers and probation officers, supplemented by library research. Findings indicate the need for comprehensive intervention strategies to ensure protection, rehabilitation, and reintegration. The study contributes to scholarship and practice by aligning case management with the National Child Policy and the United Nations Convention on the Rights of the Child, while offering practical insights to improve the handling of children beyond control in Terengganu.
