Abstract

Telah dilakukan sintesis dan karakterisasi lapisan tipis opal menggunakan metode deposisi horizontal dengan penambahan frekuensi vibrasi. Sintesis dilakukan pada suhu ruang dengan variasi frekuensi vibrasi 75 Hz, 200 Hz, 300 Hz, dan 400 Hz menggunakan speaker dalam keadaan volume tetap. Karakterisasi dilakukan menggunakan Mikroskop Optik, SEM (Scanning Electron Microscopy) dan Spektrofotometer UV-Vis. Hasil mikroskop optik menunjukkan permukaan sampel dengan frekuensi vibrasi rendah lebih homogen dan tebal dibandingkan frekuensi vibrasi tinggi. Hasil SEM menunjukkan lapisan multilayer terbentuk pada semua sampel. Spektrum absobsi spektrofotometer UV-Vis menunjukkan nilai absorbansi maksimum tertinggi pada panjang gelombang 588 nm dengan nilai absorbansi 0,2. Semakin tinggi frekuensi vibrasi yang digunakan, semakin kecil nilai absorbansi dan nilai FWHM. Thin opal films have been synthesized using horizontal deposition method modified applying the addition at frequency vibration. Synthesizing was carried out with at room temperature with frequency vibration of 75, 200, 300, and 400 Hz. Characterization was carried of using optical microscope, SEM (Scanning Electron Microscopy) and UV-Vis Spectrophotometer. Characterization with optical microscope shows that small frequency vibration thickner homogenity of opal sample. SEM show that multilayer layer is all sample deposition with frequency vibration 75 Hz, 200 Hz, 300 Hz and 400 Hz. The UV-Vis spectra show that the highest maximum absorbance of 0,2 at wavelength of 588 nm for frequency vibration of 75 Hz. The higher the vibration speed used, the smaller the maximum absorbance value and the smaller the FWHM value.

Abstract

The spinel ferrite material ZnFe2O4 was synthesized using a green synthesis approach by the hydrothermal method. In the synthesis, 2M NaOH was used as a mineralizer and betel leaf extract with varying volumes of 1, 3, 5, and 7 mL as a capping agent, then continued with calcination at 500, 600, and 700°C. Several devices, such as XRD, FT-IR, SEM-EDX, DRS-UV-Vis, and VSM, were used to characterize the synthesized ZnFe2O4 material. The pattern of XRD indicated that the ZnFe2O4 material has a cubic structure, where the increase in crystal size was after calcination. The Fourier Transform Infra-Red (FT-IR) spectrum shows the Fe-O interaction at wave numbers 427-417 cm-1, which is located on the octahedral side, while the Zn-O interaction at wave numbers 534-510 cm-1, which is located on the tetrahedral side in spinel ferrite structure. From the DRS UV-Vis spectrum pattern and band gap values, it was found that the material absorbs light in the visible region. Scanning Electron Microscope (SEM) images show that the morphology of the synthesized material is circular. The Vibrating Sample Magnetometer (VSM) hysteresis curve shows that the synthesized ZnFe2O4 has paramagnetic properties. The synthesized ZnFe2O4 material has photocatalytic activity towards phenolic compounds with a degradation percentage reaching 62.2%, and this material is active as an antibacterial with an inhibition area of 14.4 for S. aereus bacteria.

Abstract

AbstrakArtikel ini berfokus pada pembuatan sabun cuci piring dari texaphone untuk meningkatkan pengetahuan ibu-ibu PKK di Kelurahan Dumai Kota. Banyak orang yang mulai meninggalkan metode konvensional memakai abu untuk mencuci piring dan lebih suka menggunakan sabun cuci piring cair sehingga keperluan akan sabun cuci piring semakin meningkat. Dengan adanya kesempatan tersebut, produk sabun cair dapat dengan mudah dijumpai di pasaran dengan jenis yang beragam. Tujuan dari artikel ini ialah agar menambah pemahaman terkait produksi sabun cuci piring cair. Pembuatan sabun cuci piring dari texaphone adalah proses yang mudah. Sabun cuci piring merupakan bahan yang sudah menjadi kebutuhan sehari-hari terutama bagi ibu rumah tangga, mahalnya harga produk sabun cuci piring di pasaran dapat diatasi dengan memproduksi sabun cuci piring sendiri dengan kualitas yang baik dan lebih ekonomis yang dapat digunakan untuk keperluan sehari-hari. Dalam artikel ini digunakan metode diskusi dan praktek yang terbagi atas dua tahapan yakni tahap persiapan dan tahap pelaksanaan kegiatan. Hasil yang diharapkan ibu-ibu PKK dapat terampil membuat sabun cuci piring dari texaphone di Kelurahan Dumai Kota dan dapat membantu meningkatkan perekonomian keluarga. Selain itu dengan diadakannya demonstrasi ini diharapkan dapat menolong dan mempermudah para masyarakat Kelurahan Dumai Kota untuk membeli produk sabun cuci piring ini di swalayan atau supermarket yang sangat terkemuka terlebih masih dalam situasi dan situasi Pandemi Covid-19 yang belum tahu kapan berakhir akan berdampak lebih luas bagi masyarakat terutama bagi pelaku usaha UMKM yang ada di Kelurahan Dumai Kota.Kata Kunci: Sabun Cuci Piring, Texaphone, Ekonomis AbstractThis article focuses on making dish soap from texaphone to upgrade the knowledge of PKK women in Dumai Kota Village. Most people are starting to leave the convencional method of using ashes to wash dishes and prefer to use liquid dish soap so that the need for dish soap is increasing. With this chance, liquid soap products can be easily found in the market with various types. The purpose of this article is to increase knowledge about the manufacture of liquid dish soap. Making dish soap from texaphone is an easy process. Dish soap is an ingredient that has become a daily necessity, especially for housewives, the high price of dish soap products on the market can be overcome by making your own dish soap with good quality and more economical which can be used for daily needs. This article using the method of discussion and practice which consists of two stages, namely the preparation stage and the activity implementation stage. The results of the research are expected that PKK women can be skilled at making dish soap from texaphone in Dumai Kota Village and can help improve the family's economy. In addition, holding this demonstration can help and make it easier on the Dumai Kota Urban Village community to buy this dish soap product at a supermarket or supermarket which is very reputable, especially still in the situation and condition of the Covid-19 Pandemic, which does not know when it will end, will have a wider impact on the community, especially for SMEs in the Dumai Kota Village.Keywords: Dishwashing Liquid, Texaphone Economical
