Abstract

The purpose of this study was to analyze the metal oxide content in natural clay in Pangkep Regency, South Sulawesi Province, which will be used as the basic material for making gelcasting porous ceramics. One of the basic ingredients for making ceramics is alumina silica metal oxide. This metal oxide is found in several minerals, one of which is clay minerals. The sample used in this study was natural clay in Pangkep Regency, South Sulawesi Province. The parameters studied were alumina silica content before and after natural clay was used in the synthesis of porous ceramics. The synthesis method used is the gelcasting method. The metal oxide content was analyzed using XRF and to observe the morphology of the ceramic body using SEM. The results showed that the metal oxide content for the main ceramic material in the form of alumina silica did not change significantly before and after sintering, Al2O3 was 11.98% before sintering and 11.32% after sintering while SiO2 content was 71.12% before sintering and 73.32% after sintering. It is supported by the results of the morphology of the ceramic body, natural clay that has undergone curing in the ceramic body.

Abstract

Types of meat from food products that circulating in the market can be detected by Polymerase Chain Reaction with the cytochrome b gene as a marker. The most important and characteristic component for the PCR reaction is the primer, which is an oligonucleotide that acts as an initiator in the PCR reaction. In this study, the primer designed was intended to amplify the pig cytochrome b gene. The design was carried out with the help of the Primer-BLAST application, and manually, three pairs of primers came from BLAST primers, and one pair of primers was designed manually. The primer that has been designed is tested on pork, beef, and food industry products, such as pork sausage, beef sausage, and chicken sausage. The results of PCR amplification were identified qualitatively using 1% Agarose Gel Electrophoresis and visualized using a UV transilluminator. The primer designed manually to produce the whole pig cytochrome b gene with a product size of 1140 bp has succeeded in amplifying the product and is specific because it only produces bands in pork samples, while in chicken and beef samples, it does not produce bands. The three pairs of primers suggested by Primer-BLAST could amplify the porcine cytochrome b gene with band sizes of 121 bp, 272 bp, and 262 bp, but they are not specified yet because it also can amplify the gene in beef and chicken samples. The manual primer design is the best primer and can be further used to detect foodstuffs contains pig genes by PCR.

Abstract

The purpose of this study was to use the ICP-MS method to examine the particle size of TiO2 in various forms of sunscreen, with a focus on the effectiveness of UV radiation absorption. Research methods are employed to support this research by reviewing many sources as references. ICP-MS was used to measure the size of TiO2 nanoparticles in sunscreens in various forms such as powder, cream, and spray. The particle size of TiO2 in powder form is 41.17nm, in cream form is 42nm, and in spray form is 94.5nm, according to the studies. Sunscreen in the form of a spray has the biggest particle size in terms of particle size. Absorption and scattering can be increased by using larger particles

Abstract

The many uses of gold nanoparticles in the biomedical field, including as an antimicrobial agent, prompted us to analyze the development of gold nanoparticles as antimicrobial agents research through a bibliometric approach with computational mapping analysis. The publication data used are publications from the Google Scholar database using the Publish or Perish Reference Manager software. The article's title, abstract, and publication year are used as a reference in processing publication data to make it more relevant and specific to the related topic, and the data is visualized by VOSviewer software. Found 257 highly relevant publication articles on related issues indexed by Google Scholar during the last ten years (2013 to 2022). The results show that research on associated topics has developed well because the number of publications has not decreased from 2013-2021, and until August 2022, the number of publications reached an amount equivalent to the number of publications in 2015-2017. The bibliometric results show that the publication trend of gold nanoparticles as antimicrobial agents is directed at studies on antimicrobial effect, antimicrobial property, and antiviral activity. The results of this study are expected to be used as a first step for further research on related topics.

Abstract

Ikan kayu atau skipjack tuna (Katsuwonus pelamis), adalah salah satu komoditas perikanan Indonesia yang lebih dikenal dengan sebutan lokal Cakalang fufu, yang memiliki nilai ekonomis tinggi dan mampu menembus pasar internasional. Di Sulawesi Utara khusunya sumber daya ikan jenis ini mencapai 459.800 ton/tahun. Berdasarkan laporanFDA (Food and Drug Administration) dari tahun 2001-2005 terdapat 350 penolakan pada produk tuna Indonesia, alasannya karena kandungan logam beratnya, diantaranya kadmium yang melebihi ambang batas. Tujuan dari penelitian ini adalah untuk pengembangan metodde voltammetry dalam menentukan kandungan cadmium dalam sampel ikan cakalang fufu dengan menggunakan grafit pensil sebagai electrode kerja dan menentukan batas deteksi metode ini dalam mendeteksi cadmium. Sampel daging ikan cakalang yang akan diperiksa diambil dari Pasar Tradisional Amurang Kabupaten Minahasa Selatan , provinsi Sulawesi Utara. Sampel dipreparasi setelah itu didestruksi menggunakan asam nitrat, asam perklorat, dan hydrogen peroksida. Sampel hasil destruksi kemudian dianalisis dengan metode voltammetry pulsa diferensia lmenggunakan grafit pensil sebagai electrode kerja dengan penambahan standar dimana kondisi kerja diatur untuk pembacaan dari potensial -1,0 V sampai 1,2 V. Dari penelitian ini diperoleh hasil bahwa metode voltammetri menggunakan elektrode grafit pensil dapat mendeteksi kadmium (II), rata-rata perolehan kembali 50%. Konsentrasi kadmium dalam sampel ikan cakalang fufu yang diperoleh dengan metode voltammetri menggunakan elektrode grafit pensil adalah 2,2 ppm.

Abstract

Zinc oxide nanoparticle properties that can improve the quality of biodegradable food packaging become the impetus to develop research on biodegradable food packaging with the addition of ZnO nanoparticles. However, it is not yet known whether research on this topic is still widely carried out or not. This study aims to know the development of this research topic from 2013 to 2022 through a bibliometric approach with computational mapping analysis using VOSviewer. The search for article data from Google Scholar database was carried out by entering a query language into Publish or Perish. There are 207 articles that meet the criteria after being filtered by reading the title and abstract. Based on the number of publications each year, research on this topic is relatively increasing. Based on three mapping visualizations from VOSviewer results, the relation of packaging to properties or capabilities, such as biodegradability, extending the food shelf life, and antimicrobial activity is still rarely discussed. These results can be a reference for researchers to develop research on biodegradable food packaging with the addition of ZnO nanoparticles, with a discussion focusing on these properties or capabilities.
