Abstract

Research on macrozoobenthic populations in Mariah Bandar Springs, Pematang Bandar District, Simalungun Regency, North Sumatra Province was carried out from May 2022 to June 2022. The purpose of this study was to gather information about macrozoobenthos populations in Mariah Bandar Springs and to find out about the diversity of macrozoobenthos populations in Mariah Bandar Spring Waters. This research was conducted in three locations, namely upstream, middle and downstream of Mariah Bandar Springs. There are each sub-location from each of these locations, in one location consisting of the upper, middle and lower ends. Each of the locations uses three points in macrozoobenthos sampling. Macrozoobenthos sampling using surber net. The results showed that there were 9 species of macrozoobenthos including Lumbricus sp, Thiara winteri, Enallagma nymph, Thiara scraba, Corbicula fluminea, Chironomus sp, Orthetrum glaucum larvae, Hagenius brevistylus and Euplanaria sp. Based on the Shannon-Wienner diversity index, locations I, II, III have low diversity (H' = 0.147).

Abstract

One of the primary benchmarks for evaluating the quality of higher education is the successful integration of its graduates into the workforce. Unfortunately, the Faculty of Engineering at Universitas Negeri Medan lacks a dedicated platform to facilitate the dissemination of job opportunities to its alumni and establish partnerships with employers to streamline this process. As a solution, this research endeavors to develop a web-based Alumni and Career Development Center application that serves as a bridge between the corporate sector and the industrial world, enabling alumni to access job opportunities and employers to connect online. The system design incorporates the Agile Method, UML, PHP programming language, and the MySQL database engine. However, there is still room for enhancement, particularly in integrating the candidate selection process. The testing data demonstrates promising results, underscoring the system's reliability for future implementation. The application has undergone testing and assessment, including an acceptability test with a rating of 88.32, falling within the valid range, and a user interface evaluation yielding a score of 0.916667, indicating a very high level of quality.
