Detection and Analysis of Harmful Algal Blooms and Fish Mortalities in Jakarta Bay Via Satellite Imagery | Chapter 1 | Scientific Research, New Technologies and Applications Vol. 5

The coastal region of Jakarta Bay is susceptible to fish mortality and harmful algal blooms (HAB), often triggered by human activities and environmental changes. This study analyzed data from the Terra and Aqua MODIS satellites collected between 2004 and 2015 to measure chlorophyll-a levels indicative of algal blooms. The research aimed to identify and examine fish mortality and HAB in Jakarta Bay using satellite imagery. Multispectral and hyperspectral satellite data were processed to detect harmful algae distribution and fish mortality regions, integrating field data, biological water parameters, and remote sensing data. The findings suggest satellite imagery effectively monitors chlorophyll-a concentration variations, which is crucial for HAB detection. However, severe blooms do not always result in significant fish deaths. The primary cause of fish mortality was insufficient water circulation, which led to oxygen deficiency during peak blooms. The study highlights the potential of satellite-based monitoring for identifying and managing toxic algal blooms and fish deaths, providing essential data for water resource management in Jakarta Bay. Despite limitations like cloud cover, developing an early warning system (EWS) using satellite imagery is proposed as a revolutionary solution for algal blooms. This technique is vital for establishing an EWS in Jakarta Bay.

Study of the Struck-By Hazard in the Application of Ultrasound Sensor in Construction Safety | Chapter 4 | Current Overview on Science and Technology Research Vol. 5

 Traditional building sites were simpler than modern ones, and safety management was developed to address these easier construction challenges. Currently, sensors are employed in construction safety management to provide the essential level of safety for complicated sites due to their capacity for automating operations and real-time monitoring. The purpose of the study is to evaluate the appropriateness of several sensor technologies for use in struckby hazard avoidance systems and to determine how well sensors protect construction sites from such dangers. As managing construction sites becomes more challenging, the construction industry is currently under pressure to complete projects as rapidly as possible while also fulfilling the goal of safety. To manage complex facilities and protect against potential dangers, an early warning system with ultrasonic sensors is suggested. The administration of modern construction sites with outdated safety management methodologies makes them difficult to monitor since new building techniques are being implemented at such sophisticated sites and in response to swift, ongoing changes in construction sites. The early warning system under consideration will help site managers perform their duties more effectively. Several experts have carried out numerous studies on the prevention of strike-by danger in construction. However, it isn't given enough consideration, particularly when using ultrasound sensors to protect against potential dangers. As a result, it has been established how effectively ultrasonic sensors may be used in this area of construction.
