Abstract

Ships contribute to CO2 gas emissions. The government's effort to reduce these emissions is by having Onshore Power Supply (OPS) facilities. OPS is a technology that allows ships at anchor to turn off their engines and connect to the local electricity network for electricity supply. Port of Berlian currently has 8 OPS spot managed by PT. Lamong Energi Indonesia. The use of OPS still needs to be examined using valid methods. In this research, researchers use the assessment methodology that has been used at the port of Lisbon regarding this onshore electricity facility type of port where the ship is docked (mooring vessel). In this methodology, the assessment process carried out includes data gathering and data processing processes. Apart from this process, it is necessary to review the character of the port or terminal that we will examine ships that most often use land-based electricity facilities are ships with a size of 1000-2999 GT. The use of land electricity facilities provides cost efficiency of 78%. This land electricity facility is used by General Cargo and Container type ships. These results indicate that the use of land electricity facilities is still inefficient ( 2.7%) and there is a need for further review of the implementation of existing policies.

Abstract

Environmental problems due to the lack of effective waste management have become a serious challenge in this modern era, triggering air, land, and water pollution and damaging ecosystems. triggering air, soil, and water pollution and damaging ecosystems. Waste is piling up not only in urban areas but also in rural areas due to population growth, urbanization, and increasing consumption patterns. approach 3Rs (Reduce, Reuse, Recycle) approach has become urgent to reduce dependence on landfills and minimize the impact of landfills. on landfills and minimize negative environmental impacts. Village Mantren adopted this approach by establishing the 3R TPS "Ponco Banyak" TPS 3R in 2022, which serves more than 500 homes and several customers outside the village. customers outside the village. In addition to waste collection, TPS 3R also composts and makes briquettes from recycled materials. making briquettes from recycled materials. Through systematic training and counseling training and counseling, the program increased community awareness and knowledge about 3R practices, making Karang Taruna members more knowledgeable about waste management and having the skills to make recycled products such as briquettes. waste management and have the skills to make recycled products such as briquettes that can be marketed, making Mantren Village marketable, making Mantren Village an example of sustainable waste management. sustainable waste management.

Abstract

As industries seek to improve product quality and reduce costs, automation tools like 3-phase induction motors have become indispensable due to their simplicity, cost-effectiveness, efficiency, and ease of maintenance. This study investigates the automation of monitoring for 3-phase induction motors through the integration of various components, including the A3114 Hall Effect sensor, PZEM-PP4T sensor, 20x4 LCD, ESP32 module, relay, Mitsubishi D700 inverter, and MCP 4725 sensor. Testing results show high accuracy in measuring critical motor parameters such as speed, voltage, and current. The Hall Effect sensor demonstrated an average accuracy of 4.12% compared to a tachometer, while the PZEM sensor exhibited a 0.90% accuracy for voltage and a 0.98% accuracy for current when compared to a multimeter, affirming the reliability of the system. Overall, the system provides consistent and precise measurements, transforming manual monitoring into an efficient automated process. This advancement significantly enhances the reliability and effectiveness of 3-phase motor monitoring in industrial applications

Abstract

The maritime industry, a cornerstone of global trade and commerce, relies heavily on effective communication, primarily through Maritime English. Ensuring safety, operational efficiency, and regulatory compliance on international waters necessitates proficiency in this standardized form of English. Despite its critical role, many maritime professionals struggle with Maritime English, especially speaking and critical thinking skills. This study explores how facilitated critical thinking in speaking can enhance Maritime English proficiency. Facilitated critical thinking involves instructional strategies that promote analysis, synthesis, and evaluation of information through interactive dialogues, problem-solving tasks, reflective practice, and collaborative learning. This study employs a mixed-methods approach, including quantitative and qualitative phases, to examine these strategies among maritime students and professionals. Results from paired samples statistics, correlations, and t-tests indicate significant improvements in speaking proficiency and critical thinking skills following the intervention. The findings suggest that integrating critical thinking into language instruction effectively addresses the unique challenges maritime professionals face, ultimately enhancing communication and safety in the maritime industry
