CLASS STUDY AND MAP OF FLOOD VULNERABILITY LEVELS IN THE KRUENG JREUE SUB WATERSHED ACEH Besar

The increasing intensity of land conversion in the Krueng Jreue Aceh Besar Sub-watershed due to changes in land use causes changes in the biophysical characteristics of the land. Changes in the biophysical characteristics of land cause an increase in the level of flood vulnerability. This research uses a descriptive method (survey). The research results show: The variables determining the level of flood vulnerability are based on the biophysical aspects of the land, namely: dynamic factors (rainfall, land use) and static factors (soil infiltration, slope slope). Flood Vulnerability Level Classes and Maps (TKB), consisting of: Very Vulnerable, residential areas, rice fields (42≤TKB≤50); Vulnerable, moor (34≤TKB≤41); and Medium, open land, shrubs, grasslands, secondary forests, primary forests (26≤TKB≤33), average 32.38 (medium class).Primary forests and secondary forests in non-cultivation areas, covering an area of ​​12,598.00 ha or 54.26% of the total area of ​​the Krueng Jreue Sub-watershed (23,218.06 ha), have the lowest level of flood vulnerability. Flood disasters occur in November-December, when rainfall is high, which causes residents to be exposed, physical and economic losses and land damage.

Analisis Hujan Ekstrim Probable Maximum Precipitation (PMP) menggunakan metode Hersfield dan Perhitungan Debit Banjir

Extreme rain is rain with the lowest intensity of 50 mm/24 hours or 20 mm/hour. River is an elongated surface water flow and flows from a higher place (upstream) to a lower place (downstream). The area of KIuet is 1429.93 km and the area of Kluet River is 163.51 km2 and the length of the river is 68.26 km. The problem is that Kluet Utara River experiences high rainfall, resulting in overflows that flatten agricultural land and submerge residential areas. The purpose of the study was to calculate the planned return period rainfall, analyze the PMP (probable Maximum Precipitation) value and analyze the flood discharge to evaluate the PMF (Probable Maximum Flood) value and the return flood discharge. The benefits of this research are used to see the PMF value and return period rainfall to analyze the frequency of flooding KIuet Utara Watershed (DAS). The scope of the research was to calculate rainfall and flood discharge in KIuet Utara Watershed and secondary data which includes 10 years rainfall data obtained from BMKG (Meteorology, Climatology and Geophysics Agency) Indrapuri Aceh Besar and watershed maps obtained from PT. Mediatama Indoconsult. Processing of rainfall data on return period used Log Pearson III Method and PMP used Hersfield Method while calculating the planned flood discharge using Melchior Method. The results of the research is the rainfall value for the return period for the lowest rainfall in the 2 year return period is as high as 211,836 mm and the highest rainfall for the 1000 year return period is 566,239 mm, so that the flood discharge plan for the return period for the lowest flood discharge in the 2 year return period is equal to 2061,342 m3/s and the highest flood discharge at the 1000 year return period is 5510,490 m3/s. The PMP value was obtained at 2128,432 mm so that the PMF was obtained at 20714,772 m3/s. Log Pearson III and PMP methods can be used to calculate the rainfall in KIuet Utara and the results from the rainfall are used to calculate the planned flood discharge using Melchior Method.

The impact of land use and land cover changes on ecosystem service value in Aceh Besar Regency, Aceh, Indonesia

Land use and land cover (LULC) have a significant impact on changes in the value of ecosystem services. Therefore, this study investigated the relationship between ecosystem service value (ESV) and LULC in Aceh Besar Regency by calculating nine ESV variables, namely gas regulation (GR), water supply (WS), soil formation (SF), waste treatment (WT), biodiversity protection (BP), food production (FP), raw materials (RM), recreation (RC), and culture (CT) on each type of land cover in Aceh Besar Regency in three years: 2000, 2010 and 2020. The results showed that both decades saw in all three years, there was a decrease in the value of the forest ecosystem in Aceh Besar Regency due to the addition of activities and population needs, resulting in the conversion of forest land into built-up areas. This indicates that there is a relationship between land use and land cover change and human activities that have the potential to negatively affect the value of ecosystem services.

Analysis of gravity anomaly data for identification of mineral distribution prospects in the Kuta Cot Glie area, Aceh Besar

Abstract Gravity anomaly data was analyzed using the gravity method to obtain variations in gravity values and to identify mineral distribution prospects in the Kuta Cot Glie area, Aceh Besar. The Scintrex CG-5 gravimeter instrument was used to measure gravity data. After being corrected and receiving complete Bouguer anomaly values, the variation in gravity values from the research location was shown to be in the range 75-126 mGal. There are two anomalies within gravity values that are higher and lower than the surroundings. The first one is the distribution of serpentine minerals (2.4 – 3.10 g/cm 3) with variations of 108-126 mGal. This serpentine mineral is located at the center of the research location with a total area of ± 67,500 m 2. The second anomaly is limonite mineral deposits (1.55-1.7 g/cm3) with variations in gravity values of 75-87 mGal. The limonite were found on the East and West sides of the location, with a distribution area of ±71,250 m 2. The mineral deposit of limonite is a result of weathering from serpentinite rocks, therefore, the location of limonite mineral deposits is lower than the location of serpentinite. These results are aligned with the geological conditions which is dominated by serpentinite ultramafic metamorphic rocks.

Study of physical parameters on Sargassum liquid fertilizer production and its nutrient contents

Abstract Sargassum can be used as an alternative material for liquid organic fertilizer production. Liquid organic fertilizer is more environmental-friendly than the synthetic one. In the previous research, we have reported that Sargassum from Lange Beach (Aceh Besar, Aceh, Indonesia) was potential as a source of nutrients for plants. This current work aims to evaluate the levels of plants growth hormones including auxin, cytokinin, and gibberellin. Furthermore, we also evaluated the levels of macronutrients of the Sargassum liquid fertilizer (SLF) obtained from a twenty-five-day fermentation compared with the Indonesian Agricultural Ministry Regulation of Permentan no. 70/SR./140/10/2011. Using a high-performance liquid chromatography (HPLC) analysis, we reported that the levels of auxin, cytokinin, and gibberellin were 2.546 ± 0.399 ppm; 130.093 ± 0.378 ppm; and 13.456 ± 0.783 ppm, respectively. In addition, the contents of nitrogen (N), phosphorus (P), and potassium (K) as macronutrients were 1.79 ± 0.25 %; 0.025 ± 0.005 %; and 0.15 ± 0 %, respectively. Our study also measured the physical parameters of the reactor, such as temperature and humidity, when the production was taking place. Reactor temperature during the production process was in between 31 and 32°C. Meanwhile, the humidity was in between 87 and 89%. In conclusion, this work demonstrated that SLF produced from Lange’s Sargassum had sufficient nutrients needed by plants according to the national regulation.

Morphometric variations and length-weight relationships of chue snail Faunus ater (Linnaeus, 1758) in the southwest coast estuary of Aceh, Indonesia

Abstract Chue snail, Faunus ater is commonly found on the south-west coast of Aceh. This snail is consumed by the Aceh people and is an important ingredient in the traditional food of the Acehnese. Presently, there is limited information related to chue snails in Aceh waters, including morphological variations and length-weight relationships. These details are crucial for better management planning for this species. Therefore, this research aims to analyze the morphological variations and length-weight relationships of F. ater on the southwest coast of Aceh, Indonesia. Sampling was carried out from July to August 2023 in six estuaries as the presentative of six popula tions covered six districts, namely: Jantang Aceh Besar, Kuala Teunom Aceh Jaya, Kuala Ujong Kalak Aceh Barat, Kuala Trang Nagan Raya, Kuala Lama Tuha Aceh Barat Daya, and Jembatan Kembar Aceh Singkil. A total of 60 samples from each location were used for morphometric analysis using traditional morphometric approaches and the Linear Allometric Model (LAM) for growth patterns. The results showed that the F. ater popula tion was divided into three groups based on the scatter plot, where one group consisted of four populations, namely Jantang (Aceh Besar), Teunom (Aceh Jaya), Ujong Kalak (West Aceh), Kuala Trang (Nagan Raya) and the other two groups were represented by one popula tion or location. The growth pattern of F. ater on the south-west coast of Aceh is classified as negative allometric, the rela tive weight condition factor tends to 100, and the Fulton condition factor is in the range of 1.35-3.33.

Some results from a transversely excited atmospheric carbon dioxide-laser induced breakdown spectroscopy investigation of tsunami deposit cored from Aceh Besar coastal region

Abstract We undertook an extensive analysis to examine the geochemical imprints encapsulated within the samples of the 2004 Indian Ocean tsunami deposits procured from the Seungko Mulat coastal region, nestled in the western section of Aceh Besar Regency, Aceh Province, Indonesia. In order to induce the formation of micro-plasma, a Transversely Excited Atmospheric Carbon Dioxide-Laser Induced Breakdown Spectroscopy (TEA CO2-LIBS) has been employed as the excitation source. Our investigation unveils distinct spectral signatures within every layer of the stratified tsunami deposit. We observed the unmistakable presence of salt elements (Ca, K, Mg, Na, Al), transition metals, heavy metals (Si, Fe, Ti, Ba, Sr, Cu, Cr, Pb, Mn, Ni, V), and also organic constituents (C, H, O, and N). The emission intensities of these elements exhibited a significant increase within the layers of the tsunami deposit, unequivocally setting them apart from their non-tsunami equivalents. In addition, we performed a vertical analysis of LIBS elemental emission intensity ratios, unveiling unique values for the Ca/Ti, and Si/Ti, ratios, which significantly distinguish them from all other ratios scrutinized in this exhaustive investigation. This research serves to highlight the effectiveness of TEA-LIBS as a promising and efficient optical technique for discerning the chemical profile associated with the renowned 2004 Indian Ocean tsunami deposits from Seungko Mulat Village in Aceh Province.

Qualitative Geochemical Analysis of the 2004 Indian Ocean Giant Tsunami Deposits Excavated at Seungko Mulat Located in Aceh Besar of Indonesia Using Laser-Induced Breakdown Spectroscopy

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.

Penguatan Pengetahuan Kesiapsiagaan Terhadap Bahaya Bencana Gempa Bumi dan Tsunami bagi Siswa SMAN I Lhoknga, Kabupaten Aceh Besar

Earthquakes and tsunamis are natural disasters that can occur anywhere and anytime. Knowledge about the dangers of natural disasters needs to be imparted to the community so that they can understand the types and levels of danger that may arise. This is necessary to enhance the community's capacity to deal with disasters. Reflecting on the occurrence of the 2004 Aceh Earthquake and Tsunami, which claimed hundreds of thousands of lives and caused hundreds of millions of US dollars in losses, increasing knowledge and understanding of disaster hazards needs to be continuously pursued. The repetition of these activities aligns the history of disaster events passed down through generations with the advancements in scientific knowledge and technological progress. Increasing knowledge of earthquake and tsunami hazards can be achieved, in part, through socialization efforts. One appropriate segment of society to receive reinforcement of knowledge through socialization activities is high school students, particularly the students of SMAN 1 Lhoknga, Aceh Besar Regency. Students are the younger generation whose roles can be agents of change within the wider community. Therefore, their role in the realm of disaster management needs to be supported by a good and competent capacity enhancement. Thus, students of SMAN 1 Lhoknga can understand the factors causing and the impacts arising from earthquake and tsunami disasters and actively participate in such events.

Characterization of thermophilic bacteria from Ie Seum Hot Springs, Aceh Besar, Indonesia as producers of protease enzyme

Abstract. Sabaria E, Yasmin Y, Ismail YS, Bessania MA, Putri I, Fitri L. 2024. Characterization of thermophilic bacteria from Ie Seum Hot Springs, Aceh Besar, Indonesia as producers of protease enzyme. Biodiversitas 25: 1867-1874. Thermophilic bacteria are microorganisms that can survive in high-temperature environments exceeding 75°C. The Ie Seum Hot Springs in Aceh Besar, Indonesia are known to be a place where these thermophilic bacteria inhabit. In such extreme conditions, proteins and enzymes are often denatured, making these bacteria of interest due to their ability to adapt and produce enzymes such as proteases. Proteases are called proteolytic enzymes that can be applied both in the economic and medical fields. This study aimed to isolate and identify thermophilic bacteria species that have the highest potential for protease production in Ie Seum Hot Spring, Aceh Besar by analyzing the 16S rRNA gene and characterizing them using biochemical tests. Based on the result, seven thermophilic bacterial isolates, namely BT1, BT2, BT3, BT4, BT5, BT6, and BT7 were obtained, each showing different colony characteristics. The biochemical tests also revealed differences metabolic activity of each isolate. Of these isolates, BT4 exhibited the highest proteolytic index (4.65). Additionally, the 16S rRNA gene sequence analysis showed that the BT4 strain belongs to the genus Bacillus and has high similarities to Bacillus sp., B. licheniformis and B. sonorensis. These findings suggest that BT4 has significant potential as a source of thermophilic protease enzymes.
