This article discusses social media and deviant religious behavior among teenagers. The main problem raised is why there is deviation in teenagers' religious behavior? This article comes from qualitative-literature research to obtain the latest data regarding the relationship between social media and deviant religious behavior in adolescents. The findings of this research indicate that deviations in adolescent religious behavior stem from negative use of social media. The presence of social media is actually very beneficial for human life, because social media provides various information and needs. However, when teenagers are immersed in social media, it is not uncommon for them to abandon their religious values, resulting in various violations and deviations from actual norms. In fact, Islam prohibits behavior that deviates from religious rules. Artikel ini membahas tentang media sosial dan penyimpangan perilaku keagamaan remaja. Permasalahan utama yang diangkat adalah mengapa terjadi penyimpangan perilaku keagamaan remaja? Artike ini berasal dari penelitian kualitatif-literatur untuk mendapatkan data terkini tentang kaitan media ssial dengan penyimpangan perilaku keagamaan remaja. Temuan penelitian ini menunjukkan bahwa penyimpangan perilaku keagamaan remaja bermula dari pengunaan media sosial yang negatif. Kehadiran media sosial sebenarnya bermaanfaat sekali bagi kehidupan manusia, karena media sosial menyediakan berbagai informasi dan kebutuhan. Namun demikian, ketika para remaja tenggelam dalam media sosial, tidak jarang mereka menanggalkan nilai-nilai religiusitasnya sehingga terjadi beragam pelanggaran dan penyimpangan dari norma yang sebenarnya. Padahal, Islam melarang perilaku yang menyimpang dari aturan keagamaan.

In this work, a photonic crystal fiber based on a plasmonic sensor for the early detection of tuberculosis has been designed with finite element analysis. The component is constructed with a substrate layer made of fused silica material, which is then coated with a thin film of TiO2 layer as an adhesive layer to strongly attach the Au layer with the silica fiber surface. The TiO2 layer has an optimal thickness of 45 nm, while the Au layer has a thickness of 50 nm. The sensor design has a refractive index (RI) detection range from 1.27 RIU to 1.37 RIU, it also shows a maximum wavelength sensitivity (WS), maximum amplitude sensitivity (AS), sensor resolution (SR), and sensor accuracy (SA) of 20,000 nm/RIU (x-polarized) and 17.000 nm/RIU( y-polarized), -211.38 1/RIU (x-polarized) and -211.211 1/RIU (y-polarized), 9.17 x 10−5 RIU (x-polarized) and 1 x 10−4 RIU (y-polarized), and 0.025/nm respectively. Tuberculosis exhibits a normal and infected RI range of 1.343 RIU to 1.351 RIU. Therefore, the proposed sensor design is capable of detecting four types of TB infections with high sensitivity.

This article outlines the development of a Fiber Bragg Grating (FBG) intended for use as a sensor for CH4 and CO2 gases. Following fabrication, the FBG was effectively treated with a layer of Graphene Material through a modified RF Sputtering process. This coating procedure involved introducing argon gas into the chamber and subjecting the FBG, securely held by two vacuum stages, to a temperature range of 27°C to 600°C by adjusting the power supplied to the cathode and anode, ranging from 0 to 125 Watts. Subsequently, the FBG was employed as a key sensing element within an experimental setup aimed at measuring gas concentrations within a confined space. The assessment involved analyzing the reflected signal of the FBG using an Optical Interrogator System, which demonstrated a shift in the Bragg wavelength of the reflected signal corresponding to varying gas concentrations. This study indicates promising outcomes for the Graphene-coated FBG as a gas sensor. The sensor’s sensitivity was evaluated based on the Bragg wavelength shift resulting from gas presence within the chamber. The Graphene-coated FBG exhibited sensitivities of 3.3 ppm for CH4 and 3.7 ppm for CO2, surpassing those reported in prior research efforts.
