Penelitian ini dilakukan untuk melihat pengaruh pelapisan bioplastik glukomanan dari tepung porang yang divariasikan konsentrasi senyawa flavonoid kulit nanas terhadap gugus fungsi dan sifat antibakteri pada biofoam. Bahan biofoam dalam penelitian ini terdiri dari bahan baku utama dan bahan aditif. Bahan baku utama yang digunakan dalam penelitian ini adalah pati kulit pisang dan selulosa dari serat kulit durian. Kemudian, bahan aditif yang digunakan yaitu tepung porang, polimer CMC, dan flavonoid dari kulit nanas. Bahan baku utama dicampur dan diikat oleh polimer pengikat berupa CMC. Campuran dicetak dengan metode thermopressing dengan suhu 170 oC dalam waktu 3 menit. Biofoam hasil cetakan dilapisi bioplastik glukomanan dari tepung porang yang telah divariasikan konsentrasi senyawa flavonoid (1.250, 2.500, 5.000, 10.000) ppm.

Berdasarkan hasil pengujian, daya serap air biofoam berhasil diturunkan dari 55% menjadi 7,8%, 8%, 12%, dan 9%. Hidrofobisitas tersebut diduga berasal dari bioplastik tepung porang sebagai plastizer.

The Mw6.0 Mentawai earthquake 2019 with a thrust fault mechanism and the Mw5.4 South Solok earthquake 2019 with a strike-slip fault mechanism were used as case studies for the subduction zone and Sumatran Fault, respectively. The deformation was observed using 12 SuGAr (Sumatra GPS Array) and 8 InaCORS (Indonesian Continuously Operating Reference Station) stations, which were processed using GAMIT/GLOBK software. There are differences in the deformation vectors of the two earthquakes. The Mentawai earthquake experienced larger energy accumulation than the South Solok earthquake. The coseismic phase of the Mentawai earthquake experienced the largest horizontal shift at the SLBU station, which was 15.48 mm in the direction of S29.96W, while the South Solok earthquake is found to horizontally shift the CSDH station at the size of 5.75 mm towards S11.45E. The postseismic phase of the Mentawai earthquake lasted 60 days, longer than the South Solok earthquake (20 days). The difference in deformation characteristic between these two earthquakes found in this study will be valuable information in modeling earthquakes in Sumatra.","PeriodicalId":52720,"journal":{"name":"JIF Jurnal Ilmu Fisika","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41498702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Smartphone users in Indonesia are estimated to reach 191.6 million people (70.1% of the population) in 2021. The duration of use that tends to be long will have a negative effect on the body. This is related to exposure to blue light radiation produced by smartphone screens. The use of Light Emitting Diode (LED) technology is becoming increasingly popular on smartphone screens. Although it looks white, the light emitted from the smartphone screen has a wavelength of 400 – 490 nm, which belongs to the blue light category. Two common suggestions that can be made to reduce exposure to blue light radiation are reduces unnecessarily high light levels at night and attenuates shortwave components in the spectrum. However, there are still many users who don't realize that their smartphone has a blue light filter feature. Currently, low-cost spectrometers have been developed for self-assembly, for example the papercraft spectrometer from the Public Lab. This article will focus on the analysis of blue light reduction from LED smartphone screens. There were three smartphones that were observed, i.e., one unit each with an AMOLED, OLED and Super AMOLED screen. Observations were made when the phone's built-in blue light filter feature was activated or not. The results of the spectrum analysis show that there are differences in the intensity values when the blue light filter is not activated and is activated. When the phone's built-in blue light filter is activated, the intensity generated from the screen is lower than when the filter is off. Based on the blue light intensity reduction calculation, it was found that the average reduction of the three observed smartphones ’s filter was able to reduce blue light between 52.79% - 68.78%. Smartphone with Super AMOLED screen has better blue-light spectrum reduction performance, compared with its counterparts.","PeriodicalId":52720,"journal":{"name":"JIF Jurnal Ilmu Fisika","volume":"57 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90530178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Peak ground acceleration was analyzed using Donovan and McGuire equation, and the earthquake intensity was analyzed using the Wald equation. The result of this study represented peak ground acceleration value in Malang Regency, which was varied from 23.687 â€“ 33.069 gal (Donovan attenuation equation) and 22.245 â€“ 31.705 gal (McGuire attenuation equation). While based on earthquake depth, Malang Regency had a damage capacity of IV-V MMI on an intensity scale. This intensity was equivalent to the formation of cracks in the ground. Almost all residents also feel the vibrations. The most severe damage was due to the earthquake on April 10, 2021, at 14:00:16 WIB spoiled Dampit and Bantur district's public facilities.
