Worldwide trade is conducted 80% through maritime routes, including the export and import of coal. Coal is a non-renewable energy source, often used as fuel for power plants. As technology advances, detecting metal contaminants in coal cargo becomes crucial to prevent contamination of coal with metal materials. This study aims to (1) understand the operation of a conveyor in transporting coal, and (2) assess how the Proximity inductive sensor detects metal presence. The methods used in this research include real data analysis and literature review, conducted aboard the ship. The researcher designed and developed a prototype system for this purpose. The Proximity inductive sensor is utilized to detect metal contaminants, such as aluminum, iron, and stainless steel, among the coal cargo. The research was carried out during sea practice (prola) aboard the WHS ISKANDAR 1. The findings indicate that the conveyor is driven by a DC motor, and the Proximity inductive sensor effectively detects metals to separate them from the coal cargo, thus purifying the coal from metal contaminants.

This study aims to analyze the economic and social impacts within the environmental context on the sustainability of catfish farming in Basanah Village. Environmental issues such as water quality, land availability, and land-use changes have significantly affected aquaculture practices. Moreover, the social dynamics of the surrounding community, including patterns of cooperation, public perception of catfish farming, and economic impacts on farmers’ income and welfare, are central to the investigation. This research employs a descriptive qualitative approach through field observations, in-depth interviews, and documentation involving local farmers, community leaders, and relevant stakeholders. The findings reveal that economic aspects, such as production cost efficiency and income improvement, are highly dependent on stable environmental conditions and strong social support. Conversely, environmental degradation and weak social participation hinder business development. Therefore, participatory-based policies integrating sustainable environmental management with the strengthening of local socioeconomic capacities are urgently needed. This study offers a significant contribution as a foundation for formulating empowerment strategies for environmentally and socially-based small-scale aquaculture enterprises at the village level.
 

The implementation of patient safety standards is a major challenge in healthcare services, particularly in hospitals such as RSAU Soemitro. Data indicates that there were 25 patient safety incidents in the Inpatient Installation in 2023, with falls being the most common case (9), followed by nosocomial infections, medication errors (4), and the absence of patient identification bracelets during surgery (7). This study aims to analyze the influence of clinical skills and supervisory techniques on the implementation of patient safety standards at RSAU Soemitro, with caring behavior as an intervening variable. This quantitative research employs a cross-sectional study design, using a sample of 110 nurses in the inpatient installation. Data collection was conducted using questionnaires, and data analysis was performed using SEM-PLS techniques. The results show that the implementation of patient safety standards is simultaneously influenced by clinical skills, supervisory techniques, and caring behavior. Caring behavior can be significantly influenced by both clinical skills and supervisory techniques. Additionally, the implementation of patient safety standards is influenced by clinical skills and supervisory techniques both directly and indirectly through caring behavior. Furthermore, caring behavior has been proven to be the most significant factor, contributing 53.1%. These findings suggest that hospital management should focus on interpersonal skills training to support better implementation of patient safety standards.

Human survival depends on the environment. However, the lack of human awareness in protecting the environment has caused a lot of destruction to occur. To increase human awareness and understanding, Pandawara uses TikTok social media to provide information as well as appeal to people to preserve the environment. This research aims to measure and analyze the effectiveness of TikTok social media content presented by the @PandawaGrup account as a campaign tool to increase public awareness and participation in efforts to clean the environment and the responses that occur therein. The researcher used a qualitative descriptive research method which was implemented by monitoring and analyzing the @pandawagrup account evenly. The results of this research are that the social media TikTok @pandawagrup as a campaign media in protecting the environment is considered to have a significant role because it is able to share advocacy information about the environment and there are positive impacts that emerge which can be seen from the large number of positive responses both in terms of the number of likes and good opinions in awareness of protecting the environment.

The diversity of terrestrial plants in Indonesia are very huge, including production crops such as palm oil (Elaeis sp.), teak (Tectona grandis L.), lemon (Citrus limon L.) and Aloe vera. The quality of production crops is influenced by the diversity of soil microorganisms, namely the Arbuscular Mycorrhizal Fungi (AMF). AMF plays an important role in the growth and development of the host plant. This study aims to determine the diversity of AMF in the rhizosphere of some production crops at SEAMEO BIOTROP, West Java. Research methods are soil sampling and preparation, soil sieving, AMF spore extraction and morphological identification. As a result, spore density tends to be uniform in all four plants (3 spores per 10 gram). The highest to lowest relative abundance percentage of spores on Glomus sp. (52.17%), Acaulospora sp. (34.79%) and Gigaspora sp. (13,04%). Soil, host plant and AMF factors affect the diversity of AMF.
