Abstract

The implementation of ballast water management is a very important strategic step in preventing marine environmental pollution, because ship ballast water often becomes a route for the spread of invasive alien species that have the potential to disrupt the balance of the ecosistem, harm the maritime economic sector, and endanger human health. This study focuses on ballast water management practices on the MT Timur Laut Mas 2 ship, with the aim of assessing how the procedures are implemented in order to prevent the entry of alien species, reviewing the implementation of both international and national regulations, and evaluating the performance of the Ballast Water Management Sistem (BWMS) technology applied. This study uses a descriptive qualitative method based on a case study, with data collection through interviews with ship crews and company management, direct observation on board the ship, technical documentation, and a review of supporting literature. The results of the study show that the implementation of the IMO Ballast Water Management Convention (BWMC) regulations on ships has been realized through the preparation of a Ballast Water Management Plan, detailed recording in the Ballast Water Record Book, and the use of a BWMS that relies on filtration technology and ultraviolet radiation. However, the implementation still encounters obstacles in the form of limited crew understanding of system operation, variations in water quality along the shipping route that affect filtration effectiveness, and technical obstacles in equipment maintenance. Therefore, a combination of compliance with international regulations, improving crew competency through continuous training, and optimizing sistem operations are key factors in strengthening the effectiveness of ballast water management. These findings confirm that the application of modern technology in accordance with regulatory requirements can enhance marine ecosistem protection while ensuring the sustainability of the maritime industry, thus positively contributing to environmental sustainability and the stability.

Abstract

This community service activity aims to improve students' knowledge regarding microbial isolation methods for fungi and bacteria, which form an important basis in the fields of microbiology and pharmacy. The problem encountered was the limited knowledge of high school students about basic microbiology concepts, particularly microbial isolation techniques, as this material has not been taught in depth at the secondary education level. The proposed solution was an interactive counseling session consisting of a presentation on microbial isolation methods (streak plate, pour plate, spread plate, serial dilution, and surface sterilization), followed by a rewarded question and answer session and a post-test to measure the improvement in students' understanding. The activity was carried out for Grade X students of SMA Swasta Perguruan Advent 1 Medan, totaling 32 students. The post-test results showed an improvement in students' understanding of microbial isolation material, with the percentage of correct answers increasing from 35% before the activity to 82% after the counseling session, as illustrated in a comparison chart. This activity is expected to foster students' interest in microbiology and pharmacy from an early stage.
