Abstract

Physical hazards are one of the several types of dangers in Occupational Health and Safety. Companies or industries that use machines in their work processes have the potential to cause a physical hazard. One of the physical hazards is noise. Noise exposure can have an impact on employee health, namely hearing loss. A decrease in hearing threshold values can cause communication disorders and concentration problems. Variables of sound intensity, period of work, age, and disease history can influence the reduction in hearing threshold values. The results of a preliminary study on workers at PT. X indicates the sound intensity is above the threshold value, namely 86dB and 16.6% of workers experience hearing loss. The aim of this research is to determine the factors related to the hearing threshold values of workers at PT. X. The methodology in this research uses a cross-sectional approach. This study had 30 workers as samples using total sampling techniques. The results showed that the sound intensity factors (ρ = 0.030) and disease history (ρ = 0.013) were related to the hearing threshold value. Meanwhile, the factors of work experience (ρ = 0.704) and age (ρ = 1.000) are not related to the hearing threshold value. The conclusion of this research is that there is a relationship between sound intensity and history of illness with the hearing threshold value of workers at PT. X.

Abstract

The increasing demand for renewable energy has driven the development of bioethanol as an alternative fuel to replace or blend with fossil fuels, offering high prospects in the future. Driven by these high prospects, bioethanol production has begun to be widely carried out. However, the bioethanol production process tends to be complex, including fermentation and distillation processes that require intense and strict monitoring. Monitoring of both processes consists of essential parameters that must be considered, such as temperature, pH, and ethanol content, as time series data is taken intermittently and continuously. This monitoring or supervision determines the quality and success of the bioethanol production process from biomass materials, in this case, using fermented and distilled sugarcane juice. This study aims to design and implement a bioethanol production process monitoring system based on the ESP8266 microcontroller and ESP32 SoC. Both micro modules are implemented in a hybrid with HTTP communication for data logger output on a cloud service. This system uses a DS18B20 temperature sensor, a pH sensor, and an MQ3 ethanol gas sensor programmed using the Arduino IDE. The development method used is the waterfall method. Several stages include needs, including system design, implementation, hardware and software testing, and system maintenance. The implementation results show success and satisfactory achievements from the performance analysis of the sensors used. The system can monitor parameters with low errors, <1% at temperature, <10% at pH, and can detect alcohol content up to 96% of the bioethanol produced.

Abstract

This study aims to develop a transporter robot as a learning tool for elementary and secondary school students to introduce them to robotics. The robot features a differential drive system and a lifting arm akin to a forklift system. The robot is controlled using an ESP32 microcontroller and connected to an Android application through a Firebase cloud database. Utilizing an IoT platform, the training can be conducted online, allowing students to control the robot remotely while it remains at the training location. The transporter robot is designed to provide an interactive and hands-on learning experience in robotics, enabling students to grasp fundamental concepts in robotics, programming, and control systems. The differential drive system offers excellent maneuverability, while the lifting arm allows the robot to perform tasks such as lifting and moving objects, adding functional aspects to the learning process. Test results indicate that the robot performs well under online control, with fast and accurate responses to commands from the Android application. The use of Firebase ensures stable and real-time communication between the robot and the application. This implementation not only enhances the accessibility of robotics training but also enables the development of students' STEM skills in a more flexible and affordable manner. The study concludes that an ESP32-based transporter robot with online control via an Android application and Firebase cloud database can be an effective and innovative learning tool. This tool aims to enhance students’ STEM skills -especially in programming, control systems, and mechanical design- through interactive, real-world applications.

Abstract

In Indonesia, plastic waste has become an important problem at this time, because it causes environmental pollution problems. With this, further action is needed regarding the treatment of waste utilization, one of which is by converting waste into liquid fuel. Some types of rubbish that we often encounter are plastic bottles such as plastic cups, plastic bottle caps, children's toys and margarines and others, which is one of the types of PP (polypropylene) waste. The development of current plastic waste treatment technology is to convert plastic waste into fuel oil by utilizing plastic waste to be processed as plastic fuels such as premium fuel, diesel and kerosene. Polypropylene type plastic is the type of plastic that is most widely used in daily life because it has good mechanical properties with low density, heat and moisture resistance, and has good dimensional stability. Some of the technology used to convert plastic waste, among others, by using the method of high temperature (Thermal Cracking). In this study, researchers designed a Thermal cracking device, namely an Incinerator, a plastic waste smelter with high temperature, where the modification of this tool is to use used fuel oil or residual oil. In this study, the researcher analyzed the burning time, the amount of waste mass needed for the melting process in the Incinerator. In this research, a fuel equivalent of 1.5 liters of premium fuel was produced with 10 kg of plastic waste burned in the incinerator with a burning time of 125 minutes of the pyrolysis process, with a combustion temperature of 180-250 degrees Celsius.
