Abstract

In this digital era, network speed is very important, because nowadays many people use the internet as a companion in various events. Data communication is one of the means to allow several devices to communicate with each other. To simplify and speed up network usage, the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) protocols are used as the transport layer during data transfer. In running this simulation using the Cisco Packet Tracer simulation application using bus topology as the topology type.

Abstract

Electromagnetic waves in 5G transmission in Indonesia, a cellular network based on electromagnetic waves, which has revolutionized wireless communications. This wireless technology is more advanced than previous wireless technologies (1G, 2G, 3G and 4G). Electromagnetic waves are a type of electromagnetic radiation consisting of electric and magnetic fields moving simultaneously. 5G operates at a higher frequency than previous cellular technologies. The relationship between 5G signals and electromagnetic waves and their impact on signal performance and range. Here we discuss how 5G operates at higher frequency ranges, including millimeter wave (mmWave), which offers very high data speeds and large capacities. 5G technology is a fifth generation wireless communication network that offers faster data speeds, lower latency, and greater connection capacity compared to previous generations. Of particular concern is the impact of the electromagnetic fields (EMF) generated by this technology on the environment and human health. 5G technology uses higher frequencies in the millimeter wave (mmWave) spectrum, reaching 24 to 100 GHz, in addition to low to medium frequencies also used by 4G networks. Research has shown that the electromagnetic field of 5G technology has different properties, such as shorter wavelengths so that the penetration depth into living tissue is smaller.

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

This study aims to evaluate the performance of three-phase induction motors used in cooling tower systems at PT. Polychem Indonesia Tbk. Cooling towers play an important role in maintaining production stability in the chemical industry, where motor reliability is essential to ensure continuous water circulation. This study uses a quantitative approach through an online inspection method with the main parameters measured including voltage, current, and temperature. Field observations are supplemented with literature studies and interviews with experienced technicians to strengthen the analysis. The measurement results show that the motor operates within safe limits, with voltage maintained stable below 400 V, current not exceeding the nominal current of 345 A, and operating temperature remaining below 75°C. Error analysis shows a relatively small average error percentage, namely 0.02% for voltage, 0.05% for temperature, and 0.16% for current. These values are well below the ±5% tolerance limit according to the IEC 13B-23 standard, thus proving the accuracy of the measurements and the reliability of the motor's performance. These findings also indicate that a routine preventive maintenance program can minimize the risk of overvoltage, overcurrent, and overheating. Thus, it can be concluded that the GM-315 A three-phase induction motor is still operating reliably, efficiently, and safely in supporting the cooling tower system at PT. Polychem Indonesia Tbk Abstrak Penelitian ini bertujuan untuk mengevaluasi kinerja motor induksi 3 fasa yang digunakan pada sistem cooling tower di PT. Polychem Indonesia Tbk. Cooling tower berperan penting dalam menjaga kestabilan produksi pada industri kimia, di mana keandalan motor sangat dibutuhkan untuk memastikan sirkulasi air berjalan kontinu. Penelitian ini menggunakan pendekatan kuantitatif melui metode on-line inspection dengan parameter utama yang diukur meliputi tegangan, arus, dan suhu. Observasi lapangan dilengkapi dengan studi literatur serta wawancara dengan teknisi berpengalaman guna memperkuat analisis. Hasil pengukuran menunjukkan bahwa motor beroperasi dalam batas aman, dengan tegangan terjaga stabil di bawah 400 V, arus tidak melebihi arus nominal 345 A, dan suhu operasional tetap berada di bawah 75°C. analisis error menunjukkan nilai rata-rata persentase error yang relatif kecil, yaitu 0,02% untuk tegangan, 0,05% untuk suhu, dan 0,16% untuk arus. Nilai ini jauh di bawah batas toleransi ±5% sesuai standar IEC 13B-23, sehingga membuktikan tingkat akurasi pengukuran serta keandalan kinerja motor. Temuan ini juga mengindikasikan bahwa program pemeliharaan preventif yang dilakukan secara rutin mampu meminimalkan risiko terjadinya overvoltage, overcurrent, maupun overheating. Dengan demikian, motor induksi 3 fasa GM-315 A dapat disimpulkan masih bekerja dengan andal, efisien, dan aman dalam mendukung sistem cooling tower di PT. Polychem Indonesia Tbk
