Abstract

This study aims to develop a smart glass system with heat sensor-based lighting control for Smart Home applications. The developed system integrates temperature (thermal) sensors and light-dependent resistors (LDR) to detect temperature changes and light intensity in the room, allowing the automatic and energy-efficient adjustment of lighting. By using smart glass technology that can alter its transparency, the system is designed to create a comfortable environment for the occupants while reducing unnecessary energy consumption. The research includes system design, sensor selection and testing, hardware and software implementation, as well as system performance evaluation. The testing results show that the thermal sensor can accurately detect temperature changes, while the LDR can measure light intensity with precision. The system successfully adjusts the lighting based on temperature and light changes, saving up to 30% of the energy typically used for lighting. The system provides a more comfortable environment for the occupants, as the lighting is adjusted according to the surrounding conditions. However, there are challenges such as dependence on external conditions and relatively high implementation costs. This study recommends further development to improve the system's effectiveness and reduce production costs, enabling the wider application of this technology.

Abstract

This article discusses the design and simulation of an Arduino Uno microcontroller-based parking sensor system that uses HC-SR04 ultrasonic sensors to detect the distance of objects in the parking area. The project is implemented and tested through the Wokwi online simulation platform. This approach aims to provide an effective solution in prototyping parking sensor systems that is cost-effective and easily accessible. Simulation using Wokwi allows the development and testing of code and electronic circuits without physical hardware, making it easier to test the functionality of sensors and microcontrollers. Simulation results show that the HC-SR04 sensor can detect distance with sufficient accuracy and activate notifications based on a certain distance, which is relevant in the application of automated parking systems.

Abstract

The development of communication technology, especially mobile phones, has brought significant changes to everyday life. Their widespread use has made cell phones not only a communication tool but also a multifunctional device that influences many aspects of life. Along with the widespread use of cell phones, concerns have also emerged about the impact of electromagnetic wave radiation caused by cell phones on the human body. This research aims to analyze the effect of cell phone electromagnetic radiation on health using a literature study method, namely by taking data from several journals which are then reviewed based on the research title. And the research results obtained suggest that the radiation emitted by cellphones can potentially cause health problems such as brain tumors, stress and headaches. To prevent the impact of this radiation, we as cellphone users must be more careful in their use by not using cellphones excessively and must pay attention to the visibility when looking at the screen when in use. Keywords: Health, Cell Phones, Electromagnetic Radiation.

Abstract

Three-phase induction motors are electric motors that are widely used in the industry due to their reliability and efficiency. However, these motors are prone to disturbances such as unstable voltages, overloads, and short circuits, which can cause serious damage. To protect the motor, a reliable safety system is required. This article discusses the role of magnetic contactors in the safety system of three-phase induction motors, including their working principles, types of contactors, and their application to protect motors from electrical interference. The contactor functions as an electromagnetic switch that can connect and disconnect electricity automatically, improving operator safety by enabling remote operation. In addition, this safety system is equipped with sensors that monitor electrical parameters, allowing for a quick response to disturbances. Thus, the use of contactors in the safety system of three-phase induction motors is essential to maintain reliability and safety.

Abstract

Plastic waste is a serious environmental problem because it does not decompose naturally and takes years to break down. To address this problem, an effective solution is to recycle plastic waste into economically valuable products. This study aims to design a plastic shredder machine using the Verein Deutscher Ingenieure (VDI) 2222 method. The machine is designed to improve the efficiency of plastic waste processing through faster and larger capacity shredding. The plastic shredder machine has specifications of 124 cm in height, 94.5 cm in length and 80 cm in width, with a frame made of 50x50x5 mm angle iron. It is equipped with 33 blades on two shafts, driven by a gasoline engine and capable of shredding plastic waste at a capacity of 31.5 kg/hour. The use of the VDI 2222 method ensures a structured and optimal design. The research results show that this machine is effective in reducing the volume of plastic waste and facilitating the recycling process.

Abstract

Japfa Comfeed Indonesia Tbk. Unit Makassar merupakan salah satu perusahaan yang bergerak dalam bidang produksi pakan ternak, salah satunya adalah pakan ternak konsentrat ayam petelur yaitu produk CAL 9, GOLD KLK, dan KLKS 36. Dalam proses produksinya menggunakan 3 mesin yaitu mesin Intake, mesin Mixer, dan mesin Bagging. Urutan pelaksanaan job dilakukan tanpa metode yang jelas, sehingga menghasilkan waktu penyelesaian job keseluruhan yang lama, yaitu 26.592 menit. Sehingga, diperlukan upaya untuk mengurangi seluruh waktu penyelesaian job (makespan). Waktu penyelesaian job dapat dikurangi dengan meminimalkan makespan, sehingga memungkinkan tercapainya tujuan produksi dan peningkatan kapasitas produksi. Tujuan dari penelitian ini adalah untuk menemukan urutan job terbaik untuk mencapai makespan yang sesingkat mungkin. Berdasarkan hasil penelitian yang telah dilakukan, metode penjadwalan produksi Campbell Dudek Smith memberikan hasil yang optimum dengan menghasilkan total makespan time sebesar 13303,6 menit dengan menggunakan urutan job yang dikerjakan yaitu dimulai dari produk GOLD KLK – CAL 9 – KLKS 36. Dengan selisih waktu yang dihasilkan sebesar 13288,4 menit dari kondisi awal perusahaan sebelum menerapkan metode tersebut.

Abstract

A ship is a type of floating structure that is specifically designed to move on the surface of sea water. This structure provides the ability for the ship to carry out various functions, from transporting goods, carrying passengers, to carrying out various other maritime operations. The advantage of a ship lies in its ability to move stably and efficiently in the midst of various dynamic marine environmental conditions. The direction of the ship's movement is controlled by the steering system, which is a crucial component in maintaining the smoothness and accuracy of the ship's journey. This steering system consists of various elements, one of which is the Rudder Stock. Rudder Stock has a vital role in the steering system because it functions as a link between the steering and the ship's propulsion system. Inside the Rudder Stock, there is another important component, namely the Seal. The Seal has the main function of withstanding pressure during ship operations, so that it can prevent leaks that can damage the steering system and other mechanical components. To evaluate the performance of the Seal in withstanding pressure, a pressure analysis was carried out using a numerical method based on Computational Fluid Dynamics (CFD) software, namely ANSYS. The results of the study showed that the total working pressure on the Rudder Stock Seal reached 0.766 bar, which is the sum of the maximum hydrostatic pressure of 0.432 bar and the maximum fluid flow pressure of 0.334 bar.
