Abstract

Abstrak Kondisi geologi lokal merupakan salah satu parameter yang mempengaruhi tingkat kerusakan akibat gempabumi. Kondisi geologi kota Bengkulu telah digambarkan oleh nilai Ground Shear Strain (GSS) yang diperoleh dari hasil analisis enam puluh tujuh data mikrotremor yang dipasang di setiap jenis formasi geologi. Berdasarkan hasil analisis, nilai GSS kota Bengkulu relatif heterogen meskipun pada jenis formasi geologi yang sama. GSS kota Bengkulu diperoleh dan dibagi dalam tiga kelompok, diantarany 10-6 (25.37%), 10-5 (40.30%) dan 10-4 (32.84%). Variasi ini mengindikasikan adanya perbedaan ketebalan lapisan sedimen dan tingkat kekerasan batuan untuk setiap titik amat. Wilayah yang memiliki nilai GSS tinggi memiliki kesesuaian dengan kondisi lapangan yang sebenarya (berdasarkan hasil ground survey merupakan daerah bekas rawa dengan mofologi landai) dan kesesuaian dengan sejarah kerusakan akibat gempabumi besar di kota Bengkulu. Berdasarkan peta sebaran nilai GSS, potensi deformasi paling tinggi terindentfikasi di bagian barat Kota Bengkulu yaitu wilayah dengan formasi geologi undak alluvium, alluvium dan sebagian formasi andesit, sedangkan formasi geologi lainya relatif lebih aman. Dinamika lapisan tanah permukaan kota Bengkulu umumnya bersifat elastis dan berpotensi mengalami rekahan dansettlement. Struktur geologi yang relatif lunak dan lapisan sedimen yang tipis memungkinkan terjadinya penguatan efek gelombang dan resonansi tinggi ketika gempabumi terjadi. Kata-kata kunci: Kondisi geologi lokal kota Bengkulu, Ground Shear Strain, deformasi. Abstract Local geology condition has become one of the most parameters which affected damage level of earthquake. Geology condition of Bengkulu city has been described by Ground Shear Strain (GSS) value that obtained by sixty seven microtremor data analysis result what instaled on each geology formation types. According analysis result, GSS value of Bengkulu city was heterogeneous relatively in spite of similar geology formation type. GSS in Bengkulu City has obtained and be divided to three category, including 10-6 (25.37%), 10-5 (40.30%) and 10-4 (32.84%). These variations indicate differences in the thickness of sediment layer and rock solidity level of sites. The Areas of high value of GSS have compatibility with actual field conditions (Based on ground survey, it was swamp area and morphology ramps relatively) and have compatibility with damaged earthquake effect history of Bengkulu city. According map of GSS value distributions, high potency of deformation was indicated in western of Bengkulu city area, it was alluvium terraces formation, alluvium formation and partial of andesite formation, while others were relatively safer. The dynamic characteristic of surface soil layer on Bengkulu city was elastic and potential crack and settlement.The soft geology structure relatively and thin of sediments layer would affected amplification of wave and high resonance when earthquake occur. Keywords: Local geology condition of Bengkulu city, ground shear strain, deformation of soil

Abstract

ABSTRAK   Provinsi Bengkulu terletak di antara Sumatra Fault Zone  dan Mentawai Fault Zone, yang mana merupakan sistem patahan paling berbahaya di Pulau Sumatera, Indonesia. Selain itu, gempa bumi Bengkulu tahun 2000 dengan magnitudo sebesar Mw 7,9 menyebabkan banyak korban jiwa dan harta benda di sekitar wilayah studi, dan banyak gempa lain yang merusak yang terjadi setelah gempa ini. Penentuan zona rawan gempa Kabupaten Bengkulu Selatan penting dilakukan untuk mengurangi kerusakan akibat gempa. Oleh karena itu, perekaman data mikrotremor short period dilakukan di 65 titik di daerah penelitian. Analisis data ambient noise dapat membantu mengidentifikasi local site-efect di Kabupaten Bengkulu Selatan dengan menggunakan metode Horizontal to Vertical Spectral Ratio (HVSR). Frekuensi fundamental alami berkisar antara 1.0 Hz hingga 9.3 ​​Hz, dan faktor amplifikasi berkisar antara 1.8 hingga 4.4. Nilai PGA diperoleh dari kejadian gempa bumi selama 100 tahun dan dihitung menggunakan persamaan Kanai. Hasil menunjukkan bahwa nilai PGA berkisar antara 0.18 g hingga 0.78 g. Zona rawan gempa di Kabupaten Bengkulu Selatan terbagi menjadi tiga zona, yaitu zona klasifikasi rendah (Kota Manna, Pasar Manna, Bunga mas, dan Seginim) , sedang (Pino Raya, Air Nipis, dan Ulu Manna), dan tinggi (Manna, Kedurang, dan Kedurang Ilir). Hasil penelitian ini dapat menjadi rekomendasi bagi pemangku kepentingan untuk mempertimbangkan langkah-langkah yang tepat untuk desain dan konstruksi tahan gempa di Kabupaten Bengkulu Selatan.   Kata  kunci: Gempa Bumi, HVSR, Kabupaten Bengkulu Selatan, PGA.   ABSTRACT   Bengkulu Province is between the Sumatra Fault Zone and the Mentawai Fault Zone, the most dangerous fault system in Sumatra, Indonesia. In addition, the 2000 Bengkulu earthquake with a magnitude of Mw 7.9 caused a significant loss of life and property in the study area, and many other destructive earthquakes occurred after this earthquake. Determining the earthquake-prone zone of South Bengkulu Regency is essential to reducing earthquake damage. Therefore, short-period microtremor data recording was conducted at 65 points in the study area. Analysis of ambient noise data can help identify local site effects in South Bengkulu Regency using the Horizontal to Vertical Spectral Ratio (HVSR) method. The natural fundamental frequency ranges from 1.0 Hz to 9.3 Hz, and the amplification factor ranges from 1.8 to 4.4. PGA values were obtained from a 100-year earthquake event and calculated using the Kanai equation. The results show that PGA values range from 0.18 g to 0.78 g. The earthquake-prone zones in South Bengkulu Regency are divided into three zones: low (Kota Manna, Pasar Manna, Bunga Mas, and Seginim), medium (Pino Raya, Air Nipis, and Ulu Manna), and high (Manna, Kedurang, and Kedurang Ilir). The results of this study can serve as recommendations for stakeholders to consider appropriate measures for earthquake-resistant design and construction in South Bengkulu Regency.   Keywords: Earthquake, HVSR, South Bengkulu Regency, PGA.

Abstract

DOI:10.17014/ijog.8.3.313-328Bengkulu Province is the converging path region between the Indo-Australian - Eurasian tectonic plates in the ocean and the Sumatran f ault crossing on the mainland. The condition implies that the sliding force of the slab is easy to trigger fractures and to cause the material to be relatively less elastic, resulting in high seismic intensity. This study aims to identify areas with the potential for landslides and its mapping, and to analyze the factors that cause landslides in Central Bengkulu Regency, Bengkulu Province, Indonesia. This study was conducted using rock physical parameters of ground shear strain (GSS) which were correlated with parameters of slope, slope height, Vs30 value, fault distance to measurement point, rock conditions, rainfall, and PGA value. Furthermore, these parameters were overlaid thoroughly by the statistical method of the Analytical Hierarchy Process (AHP). Data acquisition is divided into two stages, namely the secondary data collection stage and the field survey stage. Secondary data collection was carried out to support the creation of landslide potential maps, analysis, and field survey data input. Secondary data is the value of Vs 30, the distance of the fault to the measurement point, rainfall, and the PGA value. Field survey data are in the form of GSS values, slope, slope height, and rock conditions. The results of this study are identified areas that have the category of high, medium, and low landslide potential. Based on the calculated parameters, the GSS parameter is the most dominant which affects the landslide potential in the studied area.

Abstract

Geopolitical conflict in the South China Sea is a complex and complicated issue, involving several countries that are divided into claimant states and non-claimant states. Claimant states refer to countries such as China, Taiwan, the Philippines, Vietnam, Malaysia, and Brunai Darusalam that claim territory in the South China Sea, while Indonesia is included in the non- claimant state category. This is due to the development of problems that continue from year to year, while the geographical position and the South China Sea route have strategic importance. As the world's maritime axis, Indonesia must maintain a neutral position and play a role in achieving peace in the conflict by utilising opportunities in the international context. This research uses a qualitative method with descriptive analysis, by collecting data through literature sources such as books, journals, and magazines. The focus of this research is to understand the role and benefits of Indonesia's defence diplomacy in handling geopolitical conflicts in the South China Sea, both on a national and international scale. The results show that Indonesia plays an active role in realising world peace through conflict resolution in the South China Sea, by promoting peaceful resolution based on UNCLOS. In this process, Indonesia gained benefits such as the maintenance of maritime sovereignty, increased regional security and stability, strengthened bilateral relations, and became a promoter in providing peaceful solutions in accordance with international law.

Abstract

Peperangan yang ada dimuka bumi ini seperti koin yang berlainan sisi, sisi lain mendatangkan bencana, sisi yang lain mendatangkan keuntungan. Turki menjadi satu-satunya negara yang benar-benar menfaatkan situasi tersebut. Berawal dari embargo yang diberikan oleh Amerika Serikat kepada Turki karena sudah mengivasi Siprus, Turki mencoba mandiri dalam industry persenjataan dalam negeri. Pengembangan industri senjata untuk militer yang pada awalnya hanya untuk memenuhi kebutuhan pasar senjata dalam negeri dan kemudian guna memenuhi kebutuhan pasar dunia internasional. Banyak persenjataan buatan Turki yang beredar di dunia internasional. Seperti contoh nya Drone Bayraktar TB 2 yang sangat fenomenal dan mampu membuat militer rusia kerepotan menghadapinya. Militer rusia benar-benar dibuat kerepotan oleh militer ukraina dengan menggunakan Dorne Bayraktar TB 2.

Abstract

Desa Urai merupakan salah satu desa yang terkena dampak abrasi parah di Kabupaten Bengkulu Utara. Abrasi yang terjadi menyebabkan perubahan garis pantai sehingga mengakibatkan kerusakan sarana dan prasarana yang ada di pantai. Pada riset ini memperoleh data primer menggunakan metode MASW dan data sekunder berupa data garis pantai pesisir Desa Urai selama 16 tahun (2006-2022) dengan menggunakan citra satelit. Analisis perubahan garis pantai Desa Urai, Kabupaten Bengkulu Utara dari 2006 hingga 2022 menunjukkan adanya abrasi signifikan. Titik-titik utama mengalami abrasi sekitar ±8 meter/tahun, sedangkan titik dengan perlindungan pantai memiliki abrasi minimal, hanya sekitar 0,1-0,5 meter/tahun. Ini menunjukkan keberhasilan infrastruktur perlindungan pantai dalam mengurangi dampak abrasi. Penelitian menemukan perubahan garis pantai rata-rata ±8 meter/tahun. Analisis menggunakan MASW dan citra satelit menunjukkan abrasi terparah di titik 1, 2, 4, 6, dan 8 (±3,4-8 meter/tahun), sedangkan titik 3 dan 7 mengalami abrasi paling rendah (±0,1-0,5 meter/tahun). Struktur batuan pada kedalaman ±30 meter terdiri dari 3 lapisan. Penelitian bertujuan untuk mitigasi bencana abrasi demi pembangunan berkelanjutan dari pemerintah provinsi hingga desa di Desa Urai, Kabupaten Bengkulu Utara. Urai Village is one of the villages affected by severe abrasion in North Bengkulu Regency. The abrasion that occurs causes changes in the coastline, causing damage to the facilities and infrastructure on the beach. In this research, primary data was obtained using the MASW method and secondary data in the form of coastal coastal data of Urai Village for 16 years (2006-2022) using satellite imagery.

Abstract

Bengkulu City is situated within a subduction zone where the Indo-Australian and Eurasian tectonic plates converge, rendering the area highly susceptible to seismic activity. This study employs the microseismic method to assess seismic vulnerability and the subsurface rock structure at the Dendam Tak Sudah Lake Flyover Construction Site in Bengkulu City, which encompasses a swampy region. The microseismic method used was an inversion of the horizontal to vertical (H/V) spectral ratio (HV-Inv) for determining the dominant frequency (f0), amplification factor (A0), seismic sensitivity index (Kg), and shear wave velocity (Vs). The findings reveal that f0 in the study area range from 2.16 to 7.53 Hz, A0 vary from 0.40 to 3.79, and Kg values span from 0.03 to 6.04. The sedimentary layers exhibit an average thickness of 5-10 meters, with some locations showing significantly thicker sedimentary deposits. Notably, the highest seismic susceptibility is recorded at point T8. The Vs values range from 185.19 to 539.49 m/s, which are inversely proportional to the Kg values and indicate soil classifications varying from soft to medium. The overall seismic risk in the study area is moderate. These results offer key insights into geophysical and geological conditions in Bengkulu City, crucial for earthquake mitigation.
