PT. XYZ is a national company engaged in the maritime industry, including shipbuilding and repairs. In its production activities, there are welding activities in the pipe workshop. In these activities, there are workers who experience complaints in certain parts of the body because they continue to work in less ergonomic positions. This problem is usually caused by poor work posture, lifting heavy loads, or lack of work facilities that support comfort. These complaints, if not handled properly, can increase the risk of musculoskeletal disorders that have the potential to reduce worker productivity. In solving the problems that occur, worker posture measurements are carried out using the RULA and REBA methods with the Fuzzy Logic approach to determine the level of MSDS risk. The results of the RULA method work posture measurement were 7 and the REBA method was 8. The use of these two work posture measurement methods is used as input variables in the fuzzy logic approach. The results of the output value for the MSDs risk level are 6.92 where this value is included in the high category. From the results of the processing above, it can be an evaluation of improvements for non-ergonomic work postures and work facilities.

An efficient facility layout is crucial for improving productivity and operational efficiency, especially for Small and Medium Enterprises like CV. XYZ, which face space limitations and inefficient material flow. This study aims to redesign the facility layout using the Systematic Layout Planning (SLP) method to optimize material flow, reduce internal transportation, and enhance the competitiveness of CV. XYZ in the screen printing industry. A quantitative descriptive approach was employed, with data collected through observations, interviews, documentation, and literature review. The SLP stages include activity analysis, calculation of Material Handling Costs (MHC), creating a from-to chart, priority scale table, activity relationship chart, and layout simulation using Blocplan software. The results show that the proposed layout successfully reduced the distance between workstations, optimized the process flow, and decreased MHC by 7% or IDR 15,648.75. These changes enhanced production efficiency, minimized material handling time, and created a more organized and productive layout. By effectively redesigning the facility layout, CV. XYZ improved its operational efficiency.

Ergonomics aims to ensure worker comfort while doing their work. Work posture is very important to determine the effectiveness of a job. Musculoskeletal Disorders (MSDs) are characterized by injuries to muscles, tendons, ligaments, nerves, cartilage, bones, blood vessels in the hands, feet, neck, and back. This study aims to analyze work posture in order to reduce the risk of work accidents. The REBA method analyzes work postures that focus on the body parts of the neck, back, arms, wrists, and feet of workers, and considers external loads and work activities. While the JSI method focuses on effort intensity, effort duration, number of efforts per minute, hand/wrist position, work speed, duration of activity per day. With the analysis of work postures on both workers using REBA, the final score for worker 1 was 10 and for worker 2 was 8, which means that checks and changes in implementation in the work environment are needed. Then, in the analysis of the worker's body posture using the JSI method on worker 1, the JSI value was 5 and on worker 2, the JSI value was 6.75, which means that this type of work is at risk of injury so that changes in the implementation of the work environment are needed. Based on the results of the analysis of work posture using both methods, in the thin plate cutting process, it is necessary to improve facilities and the work environment.

Fire is one of the events that can cause major impacts, ranging from material losses to life safety risks. To overcome this, technology is needed that can detect and extinguish fires quickly, especially in areas that are difficult to reach or too dangerous for humans. This study aims to design and develop a prototype of an Arduino-based automatic fire extinguishing robot equipped with a fire sensor and camera. The fire sensor is used to detect the presence of a fire source, while the camera functions as a visual support tool that helps the robot navigate and identify the position of the fire more accurately. This robot is designed to be able to move independently to the fire point after successful detection. Once close enough, the robot will activate the extinguishing mechanism to put out the fire. This prototype was tested in various environmental scenarios and varying fire intensities to measure the level of detection accuracy, response speed, and effectiveness in the extinguishing process. The test results show that the robot is able to detect and extinguish small-scale fires with a high success rate. Although there are still some limitations in terms of speed and detection distance, this prototype shows great potential as a supporting technology for fire extinguishing, especially for high-risk areas. With further development, it is hoped that this robot can function as a supporting device in handling small-scale fires and as a solution to maintain human safety from direct exposure to fire risks.

Conventional blind canes have limitations in providing accurate information about the user's environmental conditions, especially in recognizing obstacles and determining location. Therefore, this study aims to design and build a smart blind cane equipped with ultrasonic sensors and a microcontroller-based GPS system. This cane is designed to help blind users detect obstacles around them and determine their location more independently. The main system of this cane consists of an ultrasonic sensor to detect the distance of obstacles in front of the user and a GPS module to track the user's location. Data from the sensors and GPS are processed by a microcontroller, which then provides feedback to the user through vibrations and sounds. When an obstacle is detected within a certain distance, vibrations will be activated to provide a warning, while location information can be accessed through an application or other supporting devices. The test results show that this blind cane has a high level of accuracy in detecting obstacles up to a distance of 2 meters and fairly good positioning accuracy with an integrated GPS system. This cane can improve the mobility and sense of security of users in different environments. Thus, this design makes a positive contribution to assistive technology for the blind, enabling them to be more independent in their daily activities.

Floods are natural disasters often caused by a combination of factors such as high rainfall, clogged waterways, overflowing upstream rivers, and various other geographical and environmental aspects. This research aims to develop a water flow monitoring system to provide accurate information to the public about potential flood occurrences. This method is based on Internet of Things (IoT) technology and long-range wireless communication technology (LoRa), which provides real-time access to water flow rate information. Based on the research, the water flow sensor has maximum and minimum limits. The pipe diameter of the water flow sensor significantly affects measurement results. Testing the transducer system in a pond using a water flow sensor can measure the water flow rate. Differences in accuracy and the impact of internet network instability cause data transmission delays from the receiver device to Blynk, as Blynk continuously provides notifications. Notifications can be sent by request or automatically triggered when the water flow rate reaches 0.3 m/s. The water flow monitoring information system is integrated through Telegram.
