Abstract

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.

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

Kegiatan ini bertujuan untuk melakukan kampanye penanganan Covid-19 di Perumahan Bukit Dewa Residence Kota Bengkulu. Berdasarkan survey awal perilaku pencegahan Covid-19, diketahui bahwa virus korona (Covid-19) adalah virus yang berbahaya (90% setuju dan 7,5% ragu-ragu dan 2,5% tidak setuju). Hal ini seiring dengan pendapat tentang kondisi saat ini masih tergolong darurat Covid-19 (95% setuju dan 5% tidak setuju). Tindakan pencegahan penyebaran Covid-19 tetap perlu dilakukan (100% responden menjawab setuju). Lebih lanjut, tindakan pencegahan Covid-19 melalui penggunaan masker saat keluar rumah, sebanyak 92,5% responden menjawab selalu dan sebanyak 7,5% menjawab kadang-kadang. Terkait sikap saling mengingatkan tentang penggunaan masker, responden menjawab 75% mengingatkan jika ada orang tidak memakai masker dan 25% menjawab masa bodoh. Terkait kebiasaan mencuci tangan atau menggunakan handsanitizer, sebanyak 87,5% responden menjawab selalu dan 12,5% menjawab kadang-kadang. Tindakan pencegahan covid-19 berupa menjaga jarak (physical distancing)  merupakan tindakan yang paling sulit dilakukan oleh masyarakat dimana 57,1% responden menjawab kadang-kadang dan 42,9% menjawab selalu. Kampanye penanganan Covid-19 yang dilakukan melalui penyampaian informasi tentang perlunya tindakan pencegahan Covid-19 seperti 3M (menggunakan masker, mencuci tangan atau menggunakan handsanitizer dan menjaga jarak). Penyampaian informasi dilakukan melalui media virtual (whatsapp grup, status whatsapp dan media sosial) dan pemasangan spanduk untuk mencegah kerumunan serta pembuatan handsanitizer. Antusias warga dalam menerima informasi dan pemahaman terhadap pentingnya tindakan pencegahan covid-19 sangat baik dimana 100% masyarakat akan menggunakan masker jika keluar rumah, selalu mencuci tangan. Namun, kebiasaan untuk menjaga jarak masih sulit dilakukan seluruh warga jika di tempat umum seperti di pasar dan di tempat umum lainnya.

Abstract

North Bengkulu has a significant level of earthquake virility. One method to identify this virginity is through research into the correlation between Peak Ground Acceleration (PGA), Peak Ground Velocity (PGV), and Modified Mercalli Intensity (MMI). The data used came from the United States Geological Survey (USGS), which is secondary data. The data processing process involves applying an empirical formula that describes the relationship between PGV and intensity, as well as PGA and earthquake intensity. Furthermore, the results of the PGA & PGV calculations are incorporated into ArcGis 10.8 to create PGA&PGV contour maps, and the relationship curves of PGA to PGV, PGA, and MMI, and PGV & MMI using Excel 2019. The results of the analysis show that the largest PGV PGA value is in Arga Makmur district which has a intensity of 4.

Abstract

Pesisir Kabupaten Bengkulu Utara merupakan daerah yang rentan terhadap perubahan garis pantai yang disebabkan fenomena abrasi pantai. Abrasi pantai yang terjadi merusak infrastruktur, permukiman warga dan daerah agrobisnis. Penelitian ini bertujuan untuk mengestimasi kecepatan perubahan garis pantai di daerah Kabupaten Bengkulu Utara menggunakan Unmanned Aerial Vehicle (UAV). Pengambilan data UAV menggunakan drone DJI Mavic 2 Pro pada bulan Oktober 2018 pada lima lokasi daerah penelitian yakni daerah pantai Padang Betuah, Lais, Serangai, Ketahun dan Pelabuhan PT. Firman. Pengolahan data menggunakan software Agisoft PhotoScan untuk mendapatkan Orthophoto. Sebagai referensi data garis pantai sebelumnya digunakan peta Rupabumi dari Badan Informasi Geospasial (BIG) tahun 1992, 2000 dan 2011 sebagai data sekunder. Metode tumpang susun digunakan untuk mendapatkan informasi perubahan pantai dengan foto UAV tahun 2018 dan data tahun 1992, 2000 dan 2011. Hasil penelitian menunjukkan bahwa nilai rata-rata kecepatan perubahan garis pantai yang telah terjadi di lima lokasi penelitian berdasarkan data UAV tahun 2018 dengan data sekunder 1992, 2000 dan 2011 adalah: Padang Betuah sebesar 19,4 m/th, Lais sebesar 19,9 m/th, Serangai sebesar 19,5 m/th, Ketahun sebesar 15,9 m/th dan Pelabuhan PT. Firman sebesar 15,7 m/th. Secara umum nilai rata-rata kecepatan perubahan garis pantai mencapai 18,1 m/th, sesuai dengan hasil pengamatan di lapangan. Perbedaan kecepatan perubahan garis pantai untuk masing-masing lokasi penelitian disebabkan oleh perbedaan morfologi/kemiringan, struktur batuan penyusun pantai, kekuatan gelombang laut dan arus sejajar pantai pada masing-masing lokasi, sehingga diperlukan kajian lanjutan berbagai disiplin ilmu untuk memahami karakteristik perubahan garis pantai di Bengkulu Utara secara komprehensif baik spasial maupun temporal.

Abstract

The phenomenon of mechanical waves propagation in rock media is difficult to detect without the use of tools. To "see" the propagation of seismic waves, tools can be used in the form of a main unit monitor on a set of digital Seismograph-16S24-P 24 geophone channel tools. The community service activity aims to provide an understanding of the basic concepts of mechanical wave propagation in rocks to senior high school students throughout Bengkulu City as an enrichment for Physics Practicum. The method used to achieve the objectives of this community service activity is carried out through the stages of Focus Group Discussion (FGD), field data acquisition, data processing, data analysis and interpretation. Activity evaluation is carried out by observing activity participants in data acquisition, data processing, data analysis and interpretation. The results of the activity show that the activity participants have a good understanding of the basic concept of mechanical wave propagation in rocks. Furthermore, Bengkulu City Physics Teachers can transmit this knowledge to senior high school students as an enrichment for Physics Practicum. The material on the application of mechanical waves to rock media can also be used as a learning tool based on disaster risk reduction in the main physics subject, according to the characteristics of the study area.
