Abstract

Seagrass beds are coastal ecosystems that have important ecological functions as a provider of habitat, food sources, protection, and reproductive areas for various marine life including Echinoderms. This study aims to analyze the diversity of Echinoderms and their relationship with seagrass distribution in Kiama Beach, Melonguane District, Talaud Islands Regency. The research was conducted in the intertidal zone at three stations using the exploration method with purposive sampling technique. Each station is divided into three plot installation zones measuring 4 × 4 meters, with observations made at low tide. Environmental parameters (temperature and pH), type and number of Echinoderm individuals, and seagrass species were recorded and analyzed using the Shannon-Wiener diversity index and product moment correlations. The results showed that the Echinoderma community consists of two classes and five species: Archaster typicus, Linckia laevigata, Culcita novagueniae, Holothuroidea scabra, and Holothuroidea forskali, with the Asteroidea class dominating (75%). The diversity index (H') value was relatively low at all stations with a range of 0.6261–0.6631. Seagrass beds consist of five species, namely Halophila ovalis, Cymodocea rotundata, Thalassia hemprichii, Halodule uninervis, and Syringodium isoetifolium, with the highest abundance found in Halophila ovalis. Correlation results showed a strong to very strong relationship between the abundance of Echinoderms and certain seagrass types (r = 0.77–0.99) as well as a strong correlation at the overall level of the station (r = 0.74). This study confirms that the presence and abundance of Echinoderms is greatly influenced by the density and composition of seagrass species. These findings provide important baseline data for the management and conservation of seagrass beds as a support for the sustainability of coastal biodiversity.

Abstract

The student admission process in many educational institutions is still conducted manually, leading to issues such as data duplication, input errors, and delays in reporting. This study designs and implements a desktop-based student registration information system using VB.NET and MySQL, equipped with an admission-status checking feature and an automated quota-management module. The system was developed using the waterfall model, consisting of requirement analysis, system design using UML, implementation, and black-box testing. Two user roles are supported: admin and student. Admin users can manage applicant data, configure program quotas, open or close the registration period, and generate reports, while student users can create accounts, complete registration forms, and independently check their admission results. The implementation results show that all core functions operate validly based on testing involving two respondents. The quota-management feature successfully restricts the number of applicants according to predetermined capacities, and the admission-status module automatically displays pass or fail results. The system improves administrative efficiency, enhances data accuracy, and reduces reliance on manual record-keeping. Therefore, this desktop application serves as an effective solution for schools requiring a reliable and efficient admission management system without depending on stable internet connectivity.
