Abstract

Solid-liquid mass transfer data is very necessary for the design of mass transfer equipment, in which the coefficient determination is influenced by the rotation speed and diameter of the stirrer. Thus, this study aims to investigate the effect of variations in stirring speed and stirrer diameter on the mass transfer coefficient of a solid-liquid system. This research was conducted in a stainlesssteel stirred vessel with a diameter of 5 – 19.5 cm and a height of 20 cm equipped with baffles. The alum used was sized to pass a 20mesh sieve and retained by a 30mesh sieve. Alum was then put into a vessel with water as a solvent and stirred with stirring speed varies from 100-500 rpm. Every 10 seconds, 5 ml of sample was taken to analyze the concentration of alum by measuring its density. This experiment was carried out with variations in the speed of the stirrer rotation and the diameter of the stirrer with a constant D/Dt ratio. The result showed that there is a relationship between the mass transfer coefficient with the variables studied for the alum-water granular system in a stirred tank. The calculation results show an average deviation error of 0.66%. The dimensionless equation can be used to accurately evaluate the mass transfer coefficient experiment.

Abstract

Air pollution is a critical environmental challenge in urban areas, particularly developing regions like Medan, Indonesia. This study aims to analyze the dynamics of PM 2.5 dispersion, identify pollution sources, and assess the role of meteorological factors in influencing air quality. Using the HYSPLIT model, the research examines pollutant transport and dispersion over ten months, specifically focusing on a high-pollution episode in May 2024. The study integrates meteorological data and local air quality measurements to simulate forward and backward trajectories at multiple altitudes. The results reveal that PM 2.5 concentrations in Medan are driven by local emissions, such as transportation and industrial activities, and transboundary pollution from biomass burning in neighboring provinces. Higher altitudes capture the influence of regional winds, while localized sources and atmospheric turbulence dominate near-surface levels. Meteorological conditions, including wind patterns, temperature stability, and rainfall, significantly affect pollutant dispersion and accumulation. By leveraging advanced modeling tools and meteorological data, the study provides a robust framework for air quality management in urban environments. These insights contribute to the broader understanding of pollution dynamics and support evidence-based strategies to protect public health and the environment.

Abstract

Workplace noise is one of the physical factors that is often overlooked, although long-term exposure can have serious impacts on cardiovascular health. In workers exposed to noise, blood pressure and heart rate often increase as the body's response to physical stress. This physiological mechanism triggered by prolonged noise can result in an increased risk of cardiovascular disorders, including hypertension and heart rhythm disorders. The purpose of this study was to analyze the effect of noise on increasing blood pressure and heart rate in workers in the workshop area, especially the dynotest room. This type of research is observational with a cross-sectional research design. Conducted in December - May 2024 with the object of research on workers exposed to noise in the workshop area, especially the dynotest room. Data were analyzed using the Logistic Regression test. The total sample was 40 workers in the workshop area and dynotest room. Data were collected from observations, room noise measurements, blood pressure, and heart rate. Based on the results of the study, the average results for the dynotest area were 83.5 dBA, while for the dynotest room, the average results were 117.8 dBA. The results of statistical tests of blood pressure and pulse rate in workers obtained a sig value = 0.001. These results indicate an increase in blood pressure and pulse rate due to noise. It is recommended for the Company to monitor workers to find out the disorders caused by noise.

Rapid restoration of clean water services, combined with strengthening community operational capacity, is essential to prevent further public health risks. This article aims to present an integrated model that combines the deployment of emergency water treatment technology with community-based technical training in a post-flash flood context in Aceh, Indonesia. The program was implemented through a participatory and phased approach, including rapid needs assessment, commissioning of a skid-mounted mobile water treatment unit, operator training, and routine monitoring. Water quality assessment results indicate a consistent reduction in physico-chemical parameters from raw water to treated water and final drinking water, demonstrating stable performance of the system under fluctuating field conditions. In addition, community satisfaction evaluation shows that most respondents expressed high satisfaction with service delivery, system performance, and program impact on health and basic water needs, particularly in terms of accessibility, system reliability, and operational ease at the local user level. The deployed unit successfully restored access to safer water for affected communities while maintaining operational stability under variable field conditions. Furthermore, the training program improved local operator competence and strengthened safe water handling practices at the household level. This integrated approach, combining non-chemical water treatment technology and community empowerment, provides a practical and replicable model for post-flood emergency drinking water supply, emphasizing recontamination risk control and community-based operational sustainability. Keywords: Flash Flood, Emergency Water Purification, Community Training, Safe Drinking Water, Disaster Response.

Abstract

ABSTRAK Kegiatan pengabdian kepada masyarakat merupakan salah satu implementasi tridarma perguruan tinggi yang berperan dalam menjawab permasalahan lingkungan secara langsung di tingkat komunitas. Namun, pelaksanaan kegiatan pengabdian masih menghadapi berbagai tantangan, seperti rendahnya keberlanjutan program, keterbatasan koordinasi antarwilayah, serta belum optimalnya peran organisasi mahasiswa sebagai penggerak utama kegiatan. Oleh karena itu, artikel ini bertujuan untuk mendeskripsikan dan menganalisis peran Ikatan Mahasiswa Teknik Lingkungan Indonesia (IMTLI) periode 2015/2016 dalam penguatan pengabdian masyarakat melalui pendekatan berbasis organisasi. Metode yang digunakan adalah pendekatan deskriptif kualitatif dengan analisis terhadap dokumentasi kegiatan, distribusi wilayah pelaksanaan, serta keterlibatan anggota dari berbagai perguruan tinggi di Indonesia. Hasil kajian menunjukkan bahwa pendekatan berbasis organisasi mampu mendukung distribusi kegiatan pengabdian secara lebih luas, meningkatkan koordinasi lintas wilayah, serta memperkuat kolaborasi antaranggota. Selain itu, keterlibatan organisasi mahasiswa secara kolektif berkontribusi dalam meningkatkan efektivitas pelaksanaan program melalui penyesuaian terhadap kondisi lokal di masing-masing wilayah. Keterbaruan kegiatan ini terletak pada model pengabdian masyarakat berbasis organisasi mahasiswa yang mengintegrasikan kapasitas individu menjadi kekuatan kolektif dalam skala nasional. Dengan demikian, kegiatan ini tidak hanya memberikan dampak langsung kepada masyarakat, tetapi juga memperkuat peran organisasi mahasiswa sebagai aktor strategis dalam pengembangan pengabdian masyarakat yang adaptif, kolaboratif, dan berkelanjutan. Pendekatan ini juga mendorong terbentuknya jaringan kolaboratif antar perguruan tinggi yang memperluas jangkauan program serta meningkatkan kapasitas organisasi dalam perencanaan, pelaksanaan, dan evaluasi kegiatan pengabdian masyarakat secara sistematis dan terukur. Temuan ini memberikan dasar pengembangan model serupa pada berbagai konteks peran organisasi mahasiswa dalam penguatan pengabdian kepada masyarakat. Kata Kunci: Pengabdian Masyarakat, Organisasi Mahasiswa, IMTLI, Teknik Lingkungan, Kolaborasi Wilayah.  ABSTRACT Community service activities represent one of the core implementations of the higher education tridharma, playing a role in addressing environmental issues directly at the community level. However, the implementation of these activities still faces several challenges, such as limited program sustainability, constrained inter-regional coordination, and the suboptimal role of student organizations as primary driving forces. Therefore, this article aims to describe and analyze the role of the Indonesian Environmental Engineering Student Association (IMTLI) for the 2015/2016 period in strengthening community service through an organization-based approach. The method used is a descriptive qualitative approach, involving analysis of program documentation, distribution of implementation areas, and the involvement of members from various universities across Indonesia. The results indicate that the organization-based approach supports a broader distribution of community service activities, improves cross-regional coordination, and strengthens collaboration among members. In addition, the collective involvement of student organizations contributes to enhancing program effectiveness through adaptation to local conditions in each region. The novelty of this study lies in the organization-based community service model that integrates individual capacities into a collective force at a national scale. Thus, these activities not only provide direct benefits to communities but also strengthen the role of student organizations as strategic actors in developing adaptive, collaborative, and sustainable community service. This approach also encourages the establishment of collaborative networks among universities, expanding program reach and improving organizational capacity in planning, implementation, and evaluation of community service activities in a systematic and measurable manner. These findings provide a foundation for developing similar models in various contexts of student organization roles in strengthening community service. Keywords: Community Service, Student Organization, IMTLI, Environmental Engineering, Regional Collaboration.
