Abstract

This study aimed to evaluate the different magnetic results of an electromagnetic induction with proton magnetometer measurements on an archaeological site. The electromagnetic induction allows measuring both the apparent magnetic susceptibility in part per thousand (ppt) and the apparent electrical conductivity in millisiemens (mS/m). A proton magnetometer measures the total magnetic intensity in nanotesla (nT), caused by the induced and remanent magnetisations. An archaeological site where historical documents indicated the presence of a 13th century fortress that built by Lamuri Sultanate was selected as a test area. The measurement were conducted by divided the study area into 10 profiles.Some standard data processing have been applied to the measured data. The result of the first survey with electromagnetic induction showed low magnetic anomalies in the buried remains of Lamuri fortress. The similar value are shown as well by low magnetic field intensity in magnetometer measurement.

Abstract

Abstract. Climate change is a global phenomenon that currently and seriously impacts the environment. Increasing concentrations of greenhouse gases have caused changes in extreme climate events. We have studied index rainfall extream trend at two meteorological stations of Sultan Iskandar Muda in Banda Aceh and Cut Nyak Dien in Meulaboh from 1982-2013. Daily rainfall data were processed using software of RClimDex to obtain the extreme rainfall index. Such indexes are extreme climate index set by the expert team for Climate Change Detection Monitoring and Indices (ETCCDMI) including of maximum 1-day and 5-days precipitation amount (RX1day and RX5day), total annual precipitation (PRCPTOT), consecutive dry days (CDD), consecutive wet days (CWD), very wet days (R95p), extremely wet days (R99p) and heavy precipitation days (R20mm). Based on our study, we found that the PRCPTOT tend to decrease, whereas occurances of RX1day and RX5day increase. The Banda Aceh station which has a monsoonal pattern is charaterized by increasing in R95p and R99p as well as but decreasing in R20mm. The CWD and CDD tend to accumulate at once. The Meulaboh station that has the type of equatorial rain show decreasing trend in R95p and R99p, but increasing trend in R20mm. The CWD and CDD occur within some days. The projection Representative Concentration Pathways (RCP) 4.5 and 8.5 from 2014-2050 showed an increasing pattern frequency of rain in Banda Aceh and a decreasing pattern in Meulaboh. Keywords: Trend, Extream Climate Index, ProjectionREFERENCE Lutgens.

Abstract

The gravity method was applied to the cultural heritage site of Cot Sidi Abdullah in Kuta Krueng Village, Samudera Pasai District, North Aceh Regency for mapping and reconstruction structure of the cultural heritage site and distribution of artifact objects buried in the subsurface. Data measurement was carried out in a grid with 2 meters spacing between the points to cover all area of the cultural heritage site. The model of gravity anomaly distribution from the vertical derivative results shows a square pattern of anomaly gravity surrounding the measurement areas. This anomaly pattern is thought as a response from the remaining walls of the site structure which are buried in the subsurface with anomalous values between 0.02 mGal/m - 0.08 mGal/m.  The estimation of the walls of the archaeological site from the anomalous response to this gravity value is proved by the excavation results in the southern part of the study area.  While the minimum value of the vertical derivative filter (-0.06 mGal/m to - 0.01 mGal/m) is the response from the area around the archaeological site.  The reconstruction results of the site based on the estimation of the walls with a length of ± 45 meters and a width of ± 40 meters.

Abstract

Magnetic gradiometer survey has been conducted on the yard of the archaeological site of Masjid Tuha Indrapuri, Aceh Besar Regency, Aceh Province. The site is one of the oldest mosques erected during the Aceh Sultanate period. Magnetic method was applied for mapping archaeological structures buried beneath the surface. Total magnetic field data were measured using Proton Precession Magnetometer with grid spacing of 2 meters between stations covering the entire area of the site. Diurnal and international geomagnetic reference field data were corrected to the measured data in order to calculate total magnetic field anomalies that were influenced by the buried magnetic objects. The total magnetic field anomalies distribution shows two elongated structures with U-shaped patterns surrounding the mosque. The patterns are also revealed in reduction to the pole and derivative vertical filters of the total field anomaly data. The anomaly patterns are considered a response from the rest of the buried fences that were built around the mosque in the past.

Abstract

Laser-induced breakdown spectroscopy (LIBS) was employed to characterize the geochemical signatures layer by layer of 2004 Indian Ocean tsunami deposits in Seungko Mulat Village, Aceh Province, Indonesia. In the LIBS experimental setup, a Nd-YAG laser beam is directed towards the deposit samples, and the resulting atomic emission lines from the laser-induced plasma are captured using a spectrometer. Our analysis reveals terrestrial indicators (Fe), heavy metals (Cu, Cr, Co, Cd), and increased emission intensity of Mg, Ca, Al, K, Si, Ba, N, and O in the 2004 Indian Ocean tsunami layers. The emission intensity ratios of several elements in the 2004 Indian Ocean tsunami deposit layers, namely Ca/Ti, Si/Ti, and K/Ti, unveil notable disparities among the elements evaluated. This indicates the possibility of utilizing these ratios as reliable geochemical markers to differentiate the layer by layer of tsunami deposits. LIBS surpasses XRF in detecting nearly all elements simultaneously and identifying both light elements and specific heavy metals (Ba, Cu, Cr, Co, Cd, Pb, Ni, V, W), exceeding XRF's detection capabilities. This study emphasizes the effectiveness of LIBS as an advanced optical technique, offering speed and promise in analyzing layer-by-layer geochemical markers of the 2004 Indian Ocean tsunami deposits in Seungko Mulat Village.

Abstract

The Boreal Summer Intraseasonal Oscillation (BSISO) is intraseasonal climate variability in addition to the Madden-Julian Oscillation (MJO) that affects weather and climate in the Indo-Pacific region including the Province of Aceh. The impact of BSISO on extreme rainfall and flooding in Aceh needs to be investigated to enhance preparedness, mitigation, and adaptation strategies against its negative impacts. The datasets use in situ daily rainfall data from 5 BMKG stations in Aceh and the BSISO indices (BSISO1 and BSISO2) during the extended boreal summer (May–October) period 2001–2020, as well as flood event data in Aceh from 2008–2020. The results of this study show that rainfall in Aceh province is influenced by BSISO variability and has the potential to increase extreme rainfall and even cause flooding in some areas in Aceh, depending on the propagation path of BSISO. The frequency of extreme rainfall in Aceh during BSISO is identified using daily rainfall beyond the 95th percentile in each BSISO phase, which increases the probability of extreme rainfall in Aceh by around 20–100% during phases 1-3 in both BSISO1 and BSISO2. During BSISO1, the probability of flooding in phases 1-3 increased by up to 90%, and BSISO2 also increased the probability of flooding in phases 1-4 by up to 72%.

Abstract

The interaction process between the atmosphere and the ocean that occurs in the Pacific Ocean and the Indian Ocean has a major impact on climate and weather conditions in Indonesia. The phenomenon that arises due to this interaction is known as El Nino - Southern Oscillation (ENSO). In addition to ENSO, other mechanisms also impact weather and climate change in Indonesia, including the Indian Ocean Dipole (IOD). This study aimed to analyze the effect of ENSO and IOD on rainfall in the Aceh region. The data used were CHIRPS rainfall data with the locations of four meteorological stations and one climatology station in Aceh, IOD index data and ENSO index data. Data processing in this study was carried out using Grid Analysis and Display System (GrADS) software and Spreadsheet for CHIRPS rainfall data, followed by processing ENSO index data and IOD index using Spreadsheet software. The analysis showed that the ENSO phenomenon has a longer occurrence than the IOD phenomenon. ENSO has a greater influence on rainfall in the Aceh region than IOD, especially La Nina, which has a weak to moderate correlation. Negative IOD and El Nino phenomena influence several observation points, but some stations do not show a correlation between rainfall and the index. The positive IOD phenomenon is strongly negatively correlated with rainfall at the observation station, which shows that positive IOD does not influence the Aceh region.

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

Radio is one of the media still used by the public either for having entertainment or gaining information. Amid the rapid growth of television and internet, radio is still exhibiting its existence. Radio s involvement on the efforts of educating Disaster Risk Reduction (DRR) to the public is crucial because it can be accessed conveniently in variety circumstances. This study focused on examining how the existence of Radio RepublikIndonesia (RRI) Banda Aceh in educating DRR efforts for the public. It discussed about how the people obtain the DRR education through some radio programs concerning to DRR. RRI Banda Aceh was chosen because it is the only one government owned radio in Banda Aceh that is responsible on educating the public through the broadcasting contents. This study was conducted by using a qualitative method. The data were collected by means of interviewing the leaders of RRI Banda Aceh and observing the recording of the radio broadcasted contents related to the DRR. This study, eventually, found that the existence of RRI Banda Aceh in educating DRR efforts was manifested in three different ways such as broadcasting disaster news, talk-shows, and public service announcements. Those three ways had their own advantages and disadvantages.
