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

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.
