Abstract

This research utilizes a frequency generator application on smartphones with the aim of enhancing students' understanding of the concept of sound resonance in closed organ pipes. The study employs a pretest-posttest design with a control group that was not selected randomly. The method used is non-probabilistic sampling (convenience sampling). The sample used in this study consists of fourth-semester Elementary Teacher Education (PGSD )students who are taking the science learning course. Data collection was conducted using a Concept Understanding Instrument Sheet. The percentage of students' concept understanding above the average increased from 40.1% to 63.4%. This indicates that the concept understanding attained improved after receiving treatment in the form of the frequency generator application. The N-Gain test results yielded an average score of 0.68.

Abstract

Urek-Urek Village with all its community diversity requires overlapping in terms of economic equality, especially in terms of fertilizer subsidies. The problem is caused by inaccurate land data so that the asset data used as the basis for distributing subsidies affects the amount of subsidies received which does not match field conditions. The implementation of subsidy management so far has been based on conventional techniques so that a capable system is needed to accommodate the problems. This study uses a user-centered design approach as the basis for designing the Land Mapping Information System (SIPETAN) application design. This study will concentrate on two main problems: the SIPETAN user interface design process and the analysis of SIPETAN users in providing agricultural information to farmers in Urek-Urek Village. This study shows practical applications that can be used for the land data collection process and to help the Urek-Urek Village organization manage it.

Abstract

The development of a Client Side Rendering (CSR)-based Single Page Application (SPA) has search engine indexability weaknesses, while Server Side Rendering (SSR) overloads server computation. This study aims to prove the efficiency of the Dynamic Rendering architecture as a middle-ground solution. Through Nginx configuration, the server detects the User-Agent to serve static pages (CSR) to human users and fully rendered pages (SSR) to bot crawlers. Experimental testing was conducted on a Virtual Private Server (VPS) using k6 with a constant load of 100 Virtual Users, Prometheus, and Grafana, as well as Document Object Model (DOM) validation via Google Search Console. The Mann-Whitney U Test results proved a significant performance difference with a p-value < 0.05. The implementation of Dynamic Rendering is highly efficient, capable of reducing CPU Utilization by 92.28% and Memory Usage by 5.14%, and increasing Request Per Second (RPS) capacity by 17.19%. Indexability validation also confirmed that crawlers successfully received the HTML document entirely. In conclusion, Dynamic Rendering is proven to be an effective architectural solution to minimize server load while ensuring optimal content visibility on search engines.
