Microstrip antena can be the main choice in various communication applications because it has a fairly light mass and small size when compared to other types of antenas such as dipole antenas, yagi and so on. To know about the workings of radar. Use the CST Studio Suite application to simulate and analyze the difference in gain of the single antena, 1x2, 1x4, 1x8 arrays that have been made. From the results obtained from Gain with single Gain 1.73 dB, Array 1x2 Gain 2.97dB, Array 1x4 Gain 5.5 dB, Array 1x8 Gain 7.46 dBA Single Microstrip antena has small dimensions that can work at high frequencies However, this single patch Microstrip Antena has a weakness in the amount of radiant power (Gain), and a large polarization angle, to reduce the weakness of this single patch Microstrip Antena.

In Indonesia, the food and beverage industry grew by approximately 2.54% from 2020 to 2021, with a total revenue of around Rp775.1 trillion according to the Central Statistics Agency (BPS). Specifically, frozen foods such as ice cream, sorbet, and frozen yogurt have gained significant popularity among various consumer groups. The primary stage in the production of frozen foods involves high-quality dough mixing. The designed system consists of an Arduino Mega 2560, load cell sensor, IR obstacle sensor, keypad, single-phase AC motor, and LCD. The load cell sensor is used to measure the weight of ingredients before the mixing process. Test results indicate that the system can weigh ingredients with high accuracy (deviation of 1.82%) and detect obstacles that may cause the motor to not rotate. The system operates in two modes: timer and automatic. In timer mode, the device can set the time according to keypad settings and automatically stop when the time is up. In automatic mode, the mixing machine rotates according to the weight of the ingredients (0.30 kg - 2 kg), with warnings if the ingredients are empty or excessive.

Three-phase induction motors are one of the main components in various industries. To ensure optimal performance and prevent damage to the motor, a reliable speed monitoring and protection system is needed. Considering the difficulty of technicians or engineers in monitoring induction motors in a factory, this is the main thing that is happening at the moment. In this research, researchers designed and implemented a LabVIEW-based 3-phase induction motor speed monitoring and protection system using a Variable Speed Drive (VSD) and controlled by OUSEAL PLC. The monitoring system design or as an HMI (Human Machine Interface) was designed using LabVIEW software via RS-485 serial communication using the Modbus RTU (Remote Terminal Unit) protocol. To set the desired motor rotation speed, namely by changing the frequency value entering the motor, this setting can be adjusted via the LabVIEW interface. Furthermore, the protection system is designed using the error code feature found on the VSD and uses a thermocouple sensor to protect the motor temperature so that if the system experiences a disturbance, the induction motor will stop automatically and then display the error code or disturbance that occurred. The designed system works in accordance with the design, control and monitoring of the rotation speed of a 3 phase induction motor which can be controlled using the LabView application interface. From the results of the research that has been carried out, it is stated that changes in the frequency value entering a 3-phase induction motor will result in a faster rotation speed of the motor produced.

Sistem monitoring dan controlling penggunaan air pada saat ini masih menggunakan alat konvensional, dimana pengguna tidak dapat mengecek dan mengontrol air yang digunakan secara jarak jauh. Era teknologi yang berkembang semakin pesat menuntut manusia untuk melakukan berbagai inovasi yang bisa mempermudah suatu pekerjaan tanpa mengurangi keakurasian hasil. Penelitian ini telah membuat sistem yang dapat melakukan pengambilan data debit air dan total penggunaan air. Selain itu, sistem ini juga dapat melakukan control penggunaan air secara otomatis. Mikrokontroller yang digunakan adalah ESP32 karena dapat dikoneksikan ke internet. Platform IoT yang digunakan adalah Ubidots sebagai penampil pada sistem monitoring. Alat yang dibuat dapat berjalan dengan baik dengan hasil uji didapatkan Pada pengujian ini didapatkan hasil pada bukaan keran 10o didapatkan debit air sebesar 0,006 Liter/detik dan pada bukaan keran 80o didapatkan nilai 0,216 Liter/detik. Nilai pada bukaan keran ini sama dengan posisi 60⁰ dan 70⁰. alasan didapat nilai berikut karena pada bukaan 60⁰ tekanan air yang mengalir sudah full sehingga Ketika diposisi 70⁰ dan 80⁰ masih memiliki debit yang sama. Selanjutnya pengujian dilakukan dengan membandingkan antara nilai yang dihasilkan oleh serial monitor dan hasil pengukuran manual menggunakan gelas ukur. Dari hasil pengujian ini didapatkan nilai selisih rata – rata pada 0,188 Liter. Selisih ini didapat dari adanya kebocoran pada selang yang masuk ke penampungan sehingga ikut terukur. Cloud ubidots mampu menampilkan data debit, volume total penggunaan dan grafik pemakaian.

Analisis Pengaruh Penggunaan AAU pada Swap RRU terhadap Kualitas Layanan Telekomunikasi di Wilayah Pusdikom Cibeureum Cimahi

2024-02-14T02:26:25+07:00

Telecommunications technology continues to undergo advancements. The enabler of communication in the field of telecommunications is the telecommunications equipment installed on a BTS tower. These devices are constantly being updated to improve the service provided by the provider to meet the needs of customers. One of the network technologies currently used is 4G LTE. To enhance the network service, one of the measures taken is performing a swap or upgrade of the telecommunications equipment on a BTS tower. The upgrade of telecommunications equipment is also influenced by the population in the vicinity of the BTS tower. This allows for the replacement of telecommunications devices with ones that have broader coverage and better signal quality. This research, we discuss the issue of network capacity shortage in the Cibeureum area, South Cimahi. This is indicated by the addition of AAUs to the BTS tower in Pusdikom, Cibeureum. This research found data that South Cimahi is the most densely populated area in the city compared to other districts. Therefore, the addition of AAUs is highly effective for this issue. It is known that the AAUs are added to replace the RRUs on the tower. This is because the capacity and transmission channels of AAUs are greater than RRUs. The addition of AAU with 32T32R specifications to the tower improves signal quality with the following parameter values: RSRP(dbm): -68, -72, -76; RSRQ(db): -11, -10, -10; and SNR(db): 1, 1, 4. These values are categorized as good, indicating that the addition of AAU to the tower can effectively increase network capacity and transmission channels, thereby improving network quality in the area.
