Abstract

Increased export-import activities on fresh food commodities in the international market led to the idea of developing new technologies in the form of cryogenic freezers using liquid nitrogen (LN2). Along with the development of preservation methods using liquid nitrogen media, we need a tool that is able to detect changes in low temperatures in LN2 storage flasks that have economic value. Therefore the purpose of this research is to make a low-temperature sensor with copper and nickel material that has an economical price. The Cu/Ni film sensor is made with an electroplating method assisted by an external magnetic field of 200 G which is installed parallel to the deposition current. The Cu/Ni film was developed by varying the concentration of the electrolyte solution. The electrolyte solution used in the deposition process consisted of a mixture of H3BO3, NiSO4, NiCl2, and H2O. Furthermore, the Cu/Ni film that was made was tested on the LN2 medium to measure its sensitivity value in response to changes in temperature. The results showed that the Cu/Ni film sensor could detect changes in the low temperature in LN2. The results of data analysis showed that the curve relationship between voltage and temperature in the sample with the 2nd concentration (C2) had the highest relationship to influence each other between the voltage and temperature variables, and the sample had the highest sensitivity value compared to the others.

Abstract

The 2D topography proffers a new challenge of modeling surface waves with a 4-point finite difference (FDM) model. Topographic representation of wave propagation over a certain area will result in loss of accuracy of the numerical model. Then from this the need for appropriate modifications to reduce calculation errors. The existing approach requires value representation as an internal extrapolation solution for temporary exterior conditions. It is finally by providing boundary conditions and initial conditions in the system. However, the scheme sometimes becomes unstable for very irregular topography. 1D extrapolation along the parallel path is known to produce a simple and efficient scheme. During extrapolation, the stability of the 1D hyperbolic Schema improved by disregarding the nearest interior boundary point, which is less than half the lattice distance. Given the limited difference so that the stencils from both sides of the central evaluation point can be used as a 2D form modification if there are not enough inside points. So that in propagation space, waves that move and change according to changes in time. It will be following the wave nature of one source that travels in the x and y fields whose amplitude will change exponentially against propagation time. It is by the nature of surface wave motion.

Abstract

Abstract: Over 30 years, the Flores region experienced earthquakes with Mw >7 twice, namely in 1992 and 2021 at shallow depths <60 km. However, the behavior of the aftershocks accompanying the quake has yet to be studied in detail. This research aims to compare the behavior of aftershocks after the main earthquake. This research uses three-lifetime analysis functions, namely, Wilber3, Mustang Web Browser, and comparison of Probability Density Function Hazard. The data used comes from IRIS data and BMKG Online Data. Through graphical analysis, it is known that the data for the time difference for aftershocks follow the RMS distribution, indicating that the Flores Sea aftershock on 12 December 1992 occurred with high intensity on the 3rd and 6th day after the main earthquake. Meanwhile, the aftershocks in the Flores Sea on 14 December 2021 tended to occur with a more even intensity during the observation period, but the power returned to high on the 7th day.Abstrak: Selama periode 30 tahun, wilayah Flores mengalami gempa dengan Mw >7 sebanyak dua kali yaitu tahun 1992 dan 2021 pada kedalaman yang dangkal <60 km. Perilaku gempa susulan yang menyertai gempa bumi tersebut masih belum diteliti dengan detil. Tujuan peneltian adalah untuk membandingkan perilaku gempa bumi susulan pasca gempa bumi utama. Penelitian ini menggunakan tiga fungsi lifetime analysis yaitu, Wilber3, Mustang Web Browser dan perbandingan Probability Density Function Hazard. Data yang digunakan bersumber dari data IRIS dan Data Online BMKG. Melalui graphical analysis, diketahui bahwa data selisih waktu gempa bumi susulan mengikuti distribusi RMS, menunjukkan bahwa gempa susulan Laut Flores 12 Desember 1992 terjadi dengan intensitas yang tinggi pada hari ke-3 dan hari ke-6 setelah gempa bumi utamanya. Sedangkan gempa bumi susulan Laut Flores 14 Desember 2021 cenderung terjadi dengan intensitas yang lebih merata selama periode pengamatan namun intensitas kembali tinggi pada hari ke-7.

Abstract

Artificial intelligence (AI) can use seismic training data to discover relationships between inputs and outcomes in real-world applications. Despite this, particularly when using geographical data, it has not been used to predict earthquakes in the Flores Sea. The algorithm will read the seismic data as a pattern of iterations throughout the operation. The output data is created by grouping based on clusters using the most effective WCSS analysis, while the input features are derived from the original international resource information system (IRIS) web service data. Given that earthquake prediction is an effort to reduce seismic disasters, this research is essential. By generating predictions, it can reduce the devastation caused by earthquakes. Using the support vector machine (SVM), hyperparameter support vector machine (HP-SVM), and particle swarm optimization support vector machine (PSO-SVM) algorithms, this study seeks to forecast the Flores Sea earthquake. According to the estimation results, the SVM algorithm’s evaluation value is less precise than that of the HP-SVM, especially the linear HP-SVM and HP-SVM Polynomial models. However, the HP-SVM RBF model’s accuracy rating is identical to that of the traditional SVM model. The improvement of the PSO-SVM model, which has the finest gamma position and a value of 9.

Abstract

Menghafal Al-Qur'an adalah usaha untuk membiasakan seorang mukmin dengan kitab sucinya. Menumbuhkan minat anak untuk menghafal Al Qur’an memang tidak semudah yang dibayangkan. Anak-anak di PPWNI (Pusat Pendidikan Warga Negara Indonesia) Klang Selangor, Malaysia terlihat tidak mampu menghafal surat-surat pendek dalam Al-Quran. Hal ini dikarenakan kurangnya dukungan bersekolah dari keluarga. Padahal, mereka adalah calon-calon generasi penerus bangsa Indonesia yang patut dibanggakan. Untuk mengatasi permasalahan di atas, tim pengabdi ini mengadakan kegiatan dalam bentuk pengenalan hafalan Qur’ an dengan metode Zahrawain bagi anak-anak di PPWNI Klang Malaysia. Metode yang digunakan dalam kegiatan ini adalah ceramah, tanya jawab, diskusi, pelatihan dan evaluasi. Dampak dari program ini adalah anak-anak tidak hanya bisa menghafal Al Qur’an saja tetapi juga dapat membaca surat yang mereka hafal. Dari hasil kegiatan dapat dilihat bahwa sebagian besar anak-anak sudah hafal dan hanya sedikit yang belum hafal surat An-Naas. Selanjutnya efek dari hafalan Al Qur’an tersebut berdampak pada ketangguhan literasi hafalan dan bacaan mereka.
