Toxicity assessment of nitric acid functionalized with iron oxide nanoparticles and sipeg as a new radiographic contrast media / Rasdin Ridwan

Engineered nanoparticles have been extensively explored in various biomedical settings including nanoparticulate imaging agents due to its promising benefits to mankind. Iodine-intolerance patients have caused alarming concerns in searching new contrast media with lower toxicity effect. However, proper potential mechanism of nanoparticles has yet to be fully established despite its early acceptance and emerging usage. By using animal model system, the aim of present study is to assess acute nanotoxicity of 14 nm iron oxide nanoparticles (IONPs) coated with nitric acid and silane-polyethylene glycol (SiPEG) in comparison to iodine. Eighteen male wistar rats were used in order to explore the underlying toxicity of IONPs in liver tissues. ·OH free radicals were elucidated by using reactive oxygen species (ROS) production assay and western blotting for the presence of p53 protein expression. The results revealed coated IONPs produced higher ROS level compared to iodine, however no statistical significant were observed. It can be hypothesized that higher amount of antioxidant has been produced by rats in iodine group in correlation to combat higher amount of ROS produced before assayed was conducted. Stronger expressions of p53 protein from the coated IONPs group were further observed. Expression of p53 protein suggested initiation of antioxidants production by the protein to ameliorate intracellular ROS production to further achieve normal redox balance in curtailing further damage. The outcomes highlighted that short-term administration of IONPs with different functionalization surfaces may be safe to be applied as radiographic contrast media

PENGEMBANGAN MODEL PEMBELAJARAN RADEC (READ, ANSWER, DISCUSS, EXPLAIN, AND CREATE) BERBANTUAN MEDIA TIKTOK EDUKATIF DALAM PEMBELAJARAN MEMBACA PUISI DI SMA/SEDERAJAT

ABSTRAK Kemampuan membaca dapat dijadikan sebagai sarana penyampaian pesan atau alat informasi yang bersumber dari tulisan. Namun, hal ini dalam pembelajaran membaca puisi memiliki beberapa kendala bahwa peserta didik kesulitan mwmbaca puisi dengan baik. Permasalahan tersebut disebabkan karena pendidik belum memaksimalkan model pembelajaran dengan metode penggunaan media yang kurang menarik. Menanggapi permasalahan tersebut, peneliti mengembangkan model pembelajaran RADEC berbantuan media TikTok Edukatif dalam pembelajaran yang sesuai dengan kebutuhan, situasi, dan kondisi di sekolah. Metode penelitian dan pengembangan yang dilakukan dalam penelitian ini adalah Research and Development (R&D). Model penelitian ini terdiri dari empat tahap, yaitu: Define (Pendefenisian), Design (Rancangan), Develop (Pengembangan), dan Disseminate (penyebaran). Subjek dalam penelitian ini adalah peserta didik kelas X SMA Lab-School UPI, SMA Kartika XIX-2, dan MAS Darul Fallaah Unismuh. Penetapan subjek tersebut dengan teknik “purposive sampling”. Teknik pengumpulan data dengan wawancara, observasi, dan angket/kuesioner. Uji kelayakan model divalidasi oleh 8 ahli dengan skor rata-rata 78% kategori layak. Keterpakaian model pembelajaran diperoleh dari respons pendidik dan peserta didik melalui penyebaran angket. Rata-rata tingkat respons guru adalah 57,5% menjawab sangat setuju, peserta didik sebanyak 66% menjawab sangat setuju. Hal tersebut menunjukkan bahwa model pembelajaran RADEC berbantuan media TikTok edukatif dalam pembelajaran membaca puisi telah layak dan berhasil diterapkan dalam proses pembelajaran, karena membuat pendidik lebih mudah dalam menyampaikan materi, serta membuat peserta didik lebih termotivasi dalam mencapai tujuan pembelajaran.

ABSTRACT The ability to read can be used as a means of conveying messages or information tools sourced from writing. However, this in learning to read poetry has some obstacles that learners have difficulty reading poetry well. This problem is caused because educators have not maximized the learning model with less interesting methods of using media. In response to these problems, researchers developed a RADEC learning model assisted by Educational TikTok media in learning that suits the needs, situations, and conditions in schools. The research and development method carried out in this study is Research and Development (R&D). This research model consists of four stages, namely: Define, Design, Develop, and Disseminate. The subjects in this study were students of class X SMA Lab-School UPI, SMA Kartika XIX-2, and MAS Darul Fallaah Unismuh. The determination of the subject is by the technique of "purposive sampling". Data collection techniques with interviews, observations, and questionnaires. The feasibility test of the model was validated by 8 experts with an average score of 78% of the viable category. The use of learning models is obtained from the responses of educators and students through the dissemination of questionnaires. The average teacher response rate was 57.5% answered strongly in agreement, 66% of learners answered strongly in agreement. This shows that the RADEC learning model assisted by educational TikTok media in learning to read poetry has been feasible and successfully applied in the learning process, because it makes it easier for educators to deliver material, and makes students more motivated in achieving learning goals.

Effective bracing system for telecommunication towers

Nowadays, towers with four-legged self-supporting system are widely used worldwide for wireless and broadcast communication purpose. However the major concern is the failure of such structure in a disaster since in wireless communication network these kinds of towers play a significant role. Thus, all these tendencies of extreme conditions are considered for designing such towers are of the utmost importance. This study was carried out to determine the effects of different heights of towers at 30 m, 40 m, 50 m, and 60 m as well as different types of bracing systems such as K and Y with respect to the wind load acting on the towers. The wind speeds considered in this study were 33.5 m-1 and 44.0 ms-1. The wind modelling and simulation of the tower was conducted using commercial available software STAAD. ProV8i. The results were compared in terms of displacement and member stress. Based on the result obtained, the displacement of towers with Y bracing system was found lesser than K bracing system approximately 36% while the member stress of the tower with K bracing system was found more than Y bracing system about 56% at wind speed 44.0 ms-1
