ABSTRAK- Kota Bengkulu merupakan daerah yang sangat rawan terhadap ancaman gempabumi. Salah satu upaya mengurangi dampak bencana gempabumi adalah melakukan analisis potensi tersebut berdasarkan data mikrotremor dan metode pembobotan statistik. Penelitian ini bertujuan memetakan dan menganalisis daerah-daerah yang rentan mengalami ancaman bahaya gempabumi. Penelitian ini dilakukan menggunakan data sekunder dan survei lapangan. Data sekunder bersumber dari penelitian-penelitian terkait, sedangkan data survei lapangan berupa data mikrotremor menggunakan metode Horizontal to Vertical Spectral Ratio (HVSR). Alat yang digunakan untuk survei lapangan berupa broadband seismometer PASI Gemini-2 triaxial geophone dengan natural freq. 2 Hz ± 10%, berat 2 kg (s.n.: 12/004). Akusisi data lapangan dilakukan selama 30 menit (360.000 samples) per titik pengukuran dengan sampling rate 5 ms (200 Hz). Selanjutnya, tumpangsusun hasil pengolahan data sekunder dan lapangan menggunakan metode pembobotan statistik Analytical Hierarchy Process (AHP), sehingga diperoleh peta potensi kerentanan gempabumi di wilayah studi. Berdasarkan hasil analisis yang ditunjukkan dalam peta kerentanan gempabumi di daerah Kota Bengkulu dalam penelitian ini, Kecamatan Gading Cempaka, Kecamatan Singaranpati, Kecamatan Selebar, sebagian kecil Kecamatan Ratu Agung, dan Kecamatan Muara Bangkahulu adalah daerah yang mempunyai potensi kegempaan tinggi, sedangkan Kecamatan Selebar adalah daerah yang mempunyai potensi kegempaan rendah. Oleh karena itu untuk daerah berisiko tinggi perlu lebih diwaspadai dan perlu perencanaan pembangunan yang mengacu kepada standar risiko bencana. ABSTRACT− Bengkulu City is an area that is very prone to earthquake threats. One of the method to reduce the impact of an earthquake disaster is to conduct a potential analysis based on microtremor data and statistical weighting methods. This study aims to map and analyze the areas have the vulnerability to experience an earthquake hazard. This study was conducted using secondary data and field surveys. Secondary data comes from related studies, while field survey data is in the form of microtremor data using the Horizontal to Vertical Spectral Ratio (HVSR) method. The instrument used for the field survey was a broadband seismometer PASI Gemini-2 triaxial geophone with natural freq. is 2 Hz ± 10%, weight is 2 kg (s.n .: 12/004). Field data acquisition was carried out for 30 minutes (360,000 samples) per observation point with a sampling rate of 5 ms (200 Hz). Furthermore, the overlay of the results of secondary and field data processing uses the statistical weighting method of Analytical Hierarchy Process (AHP), in order to obtain a map of potential the seismic vulnerability in the study area. Based on the results of the analysis shown in the seismic vulnerability map in the Bengkulu City area in this study, Gading Cempaka Sub-district, Singaranpati Sub-district, Selebar Sub-district, a small part of Ratu Agung Sub-district, and Muara Bangkahulu Sub-district were areas that had a high seismic vulnerability, while Selebar Sub-district were areas that had low seismic vulnerability. Therefore, high-risk areas need to be more vigilant and need development planning that refers to disaster risk standards.

Bengkulu city is facing groundwater problems where some of the groundwater is brackish. The study aimed to determine the structure of the subsurface layer through the propagation velocity of secondary wave (Vs) in a layer of porous medium in estimating the potential for groundwater. This research supported by resistivity data and will be validated based on the depth of the well. MASW data was processed using WinMASW Professional 5.0 software to obtain a 1D profile of the Vs value, and Res2dinv software was used to obtain a 2D cross-section of the resistivity value. The results showed a decrease in the value of Vs in the porous medium layer from 133 to 358 m/s in the first path, and from 149 to 314 m/s for the second path. The decrease in the value of Vs is in the range of groundwater potential which is close to the depth of the resident's well, with the type of porous medium layer being sands and intact clays. The subsurface profile from the Vs measurement shows a good agreement with the resistivity value profile from the Geoelectric method. So, secondary wave propagation can be used in determining groundwater potential for a depth of < 10 m

Bengkulu City is located in the subduction zone of the Indo-Australian and Eurasian plates, so it is prone to earthquake. To anticipate the impact of earthquake, disaster mitigation can be carried out, one of which is a study of the level of rock hardness in the area. This study aims to determine the level of rock hardness based on seismic wave velocity in several rock formations and to determine which rock formations have the potential to cause vulnerability to earthquakes. Field data acquisition uses the seismic refraction method with time-term inversion technique. The data obtained in the field are processed to obtain a 2-D cross-section of the subsurface seismic wave velocity values. The study results show that the level of rock hardness depends on the type of rock formation. The Andesite Rock Formation Unit (Tpan) has the highest level of hardness, while the transitional area between the Alluvium Rock Formation Unit (Qa) and the Swamp Sedimentary Rock Formation Unit (Qs) has the lowest level of hardness.

The determination of the initial of the Qomariah month is still a difference, especially in determining the initial of Ramadhan, Syawwal, and Dzulhijjah. This can happen because there are differences in the method of determination. The method is in the form of Hisab method and Rukyat method. The purpose of community service activities is to determine the initial of the month of Qomariah based on MABIMS criteria (agreement of the Minister of Religion of Brunei Darussalam, Indonesia, Malaysia, and Singapore on 27-29 June 2012 in Bali) and determine the initial of the month using computer software in the form of Accurate Hijri Calculator (AHC) ver. 2.2.1. The method used in this activity is lecture, practice, and discussion. Based on AHC software application ver. 2.2.1 shows that according to calculation 1 Ramadhan falls on Saturday April 2, 2022, but according to MABIMS criteria it falls on Sunday April 3, 2022. This is a possible difference in the start time of fasting in 2022 in Indonesia. However, for 1 Syawwal, both the calculation and the MABIMS criteria fall on the same day, Monday May 2, 2022, both in Indonesia and in other countries.

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.

DOI:10.17014/ijog.8.2.221-231Bengkulu Province, due to be crossed by Bukit Barisan Mountains has relatively large geothermal reserves. This study aims to investigate the geothermal reserves in Babakan Bogor Village, Kepahiang Regency, Bengkulu Province. The magnetotelluric (MT) method with electric and magnetic sensors was used to record data in the fields. The electric sensor consisted of three porous pots, two of which were placed horizontally (Ex, Ey) and the other one vertically (Ez) as the ground. Magnetic sensors with two coils were placed horizontally (Hx, Hy) and one vertically (Hz). The data obtained in the field are in the form of rock resistivity values which are correlated with geothermal potential, so that the reservoir could be determined. Data recording in the fields used low frequencies, i.e. 128 Hz. Data processing was done using MAPROS software to convert time-series data to EDI file types. Input data in the MAPROS software is in the form of apparent resistivity vs. depth values. Furthermore, an inversion was carried out to obtain the true resistivity value as the output of the software. ZONDMT1 and ZONDMT2 were used to model the resistivity values in one dimension (1D) and two dimensions (2D). The results showed that there were geothermal reserves in the Babakan Bogor Village, Kepahiang Regency, at a depth of 1,500 to 5,000 m.
