Numeracy literacy is intended so that students can solve practical problems related to numbers in daily life. The purpose of this study was to determine the knowledge that students have about economics learning applied to numeracy literacy. The subjects taken in this study were students of fifth-grade Elementary School, Bandung, Indonesia. The data collection instrument used a pretest-posttest which was made in the Quizizz Application. The results of this study state that the average student still didnâ€™t understand numeracy literacy. Students' understanding of the material for numeracy literacy can be improved by providing economics material via PowerPoint or YouTube which is done online from using the zoom application with educators. The results of the research show that the average post-test score for all of the sample students is 90.6% greater than the average pre-test score of 56.6% so the difference is 34%. Therefore, learning economics can be improving their numeracy literacy studentsâ€™ skills.

Zinc sulfide is a semiconductor that is widely used in various fields. Synthesis of zinc sulfide nanoparticles by microwave irradiation method has promising prospects because of its advantages, such as commercially available precursors, short reaction times, low operating temperatures, and produced high quantity and high-quality products. The purpose of this study was to evaluate the feasibility of the production of zinc sulfide from zinc nitrate hexahydrate and thioacetamide by microwave irradiation method. The evaluation was done from the engineering and economic perspectives. The feasibility analysis method from the engineering perspective was done by designing the initial production design on a large scale, whereas the analysis from an economic perspective was done by calculating various economic parameters (i.e., Gross Profit Margin, Cumulative Net Present Value, Internal Rate Return, Payback Period, Break Event Point, and Profitability Index). The engineering perspective showed that the production of zinc sulfide nanoparticles can be done on a large scale due to the commercial availability of materials and tools. Based on the economic evaluation, this project is ideal for an industrial scale. The profits increased over 20 years and the payback period was achieved within two years. We hope this study can provide references to readers, industry, and researchers regarding the feasibility analysis of the production of zinc sulfide nanoparticles by microwave irradiation method on a large scale.

The purpose of this study was to determine the feasibility of a project for the manufacture of magnesium oxide nanoparticles using the sol-gel method by evaluating both technically and economically. Evaluation from the technical side is determined by stoichiometric calculations and evaluation of the initial factory design, while the evaluation from the economic side is determined by several parameters to determine the benefits of the project to be established (Gross Profit Margin, Internal Rate Return, Break-Even Point, Payback Period, and Cumulative Net Present Values). Some of these economic evaluation parameters were analyzed to inform the production potential of magnesium oxide nanoparticles, such as determining the level of profitability of a project (Gross Profit Margin), predicting the length of time required for an investment to return the initial capital expenditure (Payback Period), predicting the condition of a production project in the form of a production function in years (Cumulative Net Present Value), etc. The results of the technical analysis show that this project can produce 1,425 kg of magnesium oxide nanoparticles per day and the total cost of the equipment purchased is 45,243 USD. Payback Period analysis shows that the investment willbe profitable after more than three years. To ensure project feasibility, the project is estimated from ideal to worst-case conditions in production, including salary, sales, raw materials, utilities, as well as external conditions such as taxes

Perkembangan masyarakat saat ini semakin didorong dan didukung oleh pertumbuhan teknologi komunikasi melalui pengujian keamanan dengan aplikasi web Google Gruyere. Berbagai kerentanan umum, seperti Cross-Site Scripting (XSS), Client State Manipulation, Cross-Site Request Forgery (CSRF), dan Path Traversal, diidentifikasi dan dianalisis. Metode penelitian meliputi identifikasi masalah, tinjauan pustaka, dan eksperimen dengan menggunakan alat pengujian penetrasi. Hasil penelitian menunjukkan bahwa pengujian keamanan yang komprehensif sangat penting untuk menjaga integritas, kerahasiaan, dan ketersediaan informasi dalam suatu sistem. Pengujian penetrasi membantu mengembangkan strategi keamanan yang lebih baik dengan mengidentifikasi kerentanan secara cepat dan akurat dan memungkinkan organisasi untuk melawan potensi ancaman keamanan sebelum dapat dieksploitasi. Menerapkan langkah-langkah keamanan yang tepat seperti sanitasi masukan, penggunaan token CSRF, dan validasi masukan dapat mengurangi risiko serangan siber dan melindungi data pengguna. Kesadaran akan ancaman dan tindakan pencegahan yang tepat sangat penting untuk meningkatkan keamanan siber aplikasi web.

The ability of students to learn mathematics, especially in solving mathematical problems, is quite low. The pandemic conditions forced distance learning so that it hampered the improvement of students' ability to solve mathematical problems and non-mathematical problems. Innovation in learning is needed to help students to always be motivated in learning mathematics. This study aims to determine how much benefit the YouTube platform is as a distance learning medium to improve students' ability to solve problems mathematically. This activity method uses a quantitative approach with the target of grade 5 elementary school students. The results showed that the post-test average of students was 83.4%, an increase of 25.9% from the pre-test results which only reached 57.5%. This shows that videos uploaded to the YouTube platform can be an effective and innovative way to improve the mathematical problem-solving abilities of elementary school students.

The Literacy Habituation to Grow Early Childhood Language Skills Through Picture Story Books in Early Childhood Education Hidayat, Linda Fasha; Nandiyanto, Asep Bayu Dani; Kurniawan, Tedi; Bilad, Muhammad Roil

Literacy is a language skill possessed by someone in communicating. Literacy habituation needs to be done from an early age because it will make children accustomed to literacy which will also be able to cultivate their imagination. At this time, many parties apply literacy to early childhood with an inappropriate process, some children are required to be able to read and write in a method that requires children to think hard. By using picture storybook media, it will foster children's literacy skills. In this quantitative method, the authors take samples from several children with observational data collection techniques, namely interviews and questionnaires. The results of data collection stated that eight out of ten children succeeded in following the literacy habits that the authors applied. Therefore, literacy is very important to be applied to early childhood so that children can have the ability to communicate effectively that can develop their potential and participate in community life in the future.
