Abstract

To get a small PCB size, it is important to put the tracks close together. When a track carries a high frequency signal (EMI source track), then the signal on that track will affect signals on other tracks, which is called the crosstalk phenomenon. The affected track is called the victim track. The result of this phenomenon is the damage to the signal on the victim track. So that the load on the victim track will receive a different signal form compared to the signal form from the source. To see this phenomenon, a module is made which consists of various configurations between the emi source track and the victim track. This configuration is distinguished by the distance between the emi source track and the victim tract, the width of the two tracks, and the length of the parallel path between the two tracks. Based on the test scenario that has been planned, the results of this study show that the highest emission value on the victim occurs when the distance between the tracks is 1 mm, the track width is 10 mm, and the length of the parallel path between the tracks is 95 mm. When the source track is given a square signal with an amplitude of 2.84 V, a frequency of 2.5 MHz, emission is obtained on the victim track is 156 mV (Near End) and 146 mV (Far End).

Abstract

Nowadays, 4G cellular service has become a basic need especially for campus communities. Information exchange and learning processes often utilize technology in this service. Block 6, floor 2 of the PCR campus consists of 2 lecturer rooms, 4 laboratories, 1 meeting room and 1 research room. Of course, this is one of the spots in PCR where 4G service is needed. Of the several 4G service providers in Indonesia, Telkomsel is the operator that has the most customers. 4G network performance can be seen in several parameters such as RSRP, RSRQ, CSFB, Throughput and SINR. These parameters are obtained through a process called Drive Test (DT). Drive Tests carried out by walking in closed areas such as inside buildings, malls, and such are called Walktests (Indoor Drive Tests). This research is focused on observing only one parameter, namely throughput. From this research, the maximum throughput value for Telkomsel's 4G network in Block 6, Floor 2, PCR Campus at the time of measurement (July 13 2023 at 16.43 WIB) was 2.18 Mbps. So when compared with the KPI set by Telkomsel, the throughput value in block 6, floor 2 of the PCR campus is in the "fairly good" category. Keywords: 4G, Drive Test, Throughput

Abstract

Pada umumnya penyortiran telur di UMKM produsen telur bebek dilakukan secara manual oleh manusia, sehingga membutuhkan tenaga kerja dan waktu yang lebih lama serta kurang efisien. Selain itu, kesalahan manusia dalam menentukan bobot telur juga dapat mempengaruhi akurasi dalam proses penyortiran. Dalam penelitian ini dibuat sebuah alat pernyortir telur bebek otomatis berdasarkan bobot. Dengan alat ini diharapkan dapat memberikan solusi atas permasalahan yang ada. Alat yang telah dibuat menggunakan konveyor untuk membawa telur secara otomatis ke sensor load cell untuk ditimbang, dan motor servo sebagai pemilah telur berdasarkan bobot yang telah ditimbang oleh sensor load cell. Hasil telur yang disortir terbagi menjadi 3 klasifikasi bobot yaitu ringan, sedang, dan berat. Data bobot-bobot telur yang telah terukur akan masuk kedalam microsoft excel dengan bantuan software PLX-DAQ. Alat penyortir telur bebek otomatis ini membutuhkan waktu 8,73 detik per butir dengan keakurasian bobot 98,36%.

Abstract

Indoor farming requires a substitute for sunlight for its growth, therefore a system was created to control the light intensity used for indoor farming using the BH1750 Sensor which has an accuracy level of 94.6% and an AC Light Dimmer as a PWM Module. It is important to remember that AC Light Dimmers regulate light intensity by cutting off some of the sinusoidal waves from the AC electric current, and this can produce side effects such as noise or electromagnetic interference (EMI) in electrical lines. In the noise conducted emission test on the AC Light Dimmer, a noise value of 80.33dBµV was obtained, which is far from the CISPR 22 Class B standard value, so a passive EMI filter with the Low Pass Filter (LPF) type was designed to be able to reduce the conducted emission noise. The passive EMI filter designed and tested has an effective dampening response even though there is a shift in the cut-off frequency of 28.7KHz from that obtained in the calculations. The Passive EMI Filter designed is capable of reducing noise conducted emissions produced by AC Light dimmers by 80.33dBµV to 26.46dBµV and produces excellent attenuation of up to 53.87dB and meets the specified standards (CISPR22 Class B).

Abstract

The mobile phone has become the communication device of choice for most people due to its practicality compared to other communication devices. A mobile phone requires electrical energy from its battery to function. Over time, the electrical energy stored in the battery depletes, and the phone needs to be recharged. A frequent problem arises when users are outside without a charger or have difficulty finding a safe power source. To address this issue, this final project proposes a solution: a secure mobile charging station that can be placed in public locations such as stations, hospitals, banks, hotels, malls, restaurants, and other venues. The paid mobile charging station consists of six charging lockers. Each locker is secured with a solenoid lock controlled by a Node MCU ESP32 microcontroller. Payment can be made using either coins or an RFID card. To charge their mobile phones, users must insert coins or swipe an RFID card. Once payment is made, users can charge their phones in the provided lockers for a specified period. System testing demonstrates high reliability, with a 100% success rate in coin validation, accurate RFID balance deductions, and seamless data transmission between the ESP32 and the database. The results indicate that the proposed system is a cost-effective, scalable, and secure solution for providing public mobile charging services in locations such as malls, hospitals, and transportation hubs.

Abstract

Peatland Forest Fires pose a serious threat, particularly in Riau, which has 3.89 million hectares of peatland and is highly vulnerable during the dry season. These fires are difficult to control because the flames can spread beneath the dry surface of the soil. One preventive measure is real-time monitoring of the water table to maintain soil moisture. Long Range (LoRa) technology, with its long-range communication and low power consumption, is more effective than cellular-based IoT systems, which are limited in remote areas. This study developed a seven-hop LoRa multi-hop system to transmit data from remote areas to a cellular network via river routes without the need for expensive infrastructure. The solution is more efficient, offering a cost reduction of up to 96%-99% compared to other methods. The system will be applied at PT Rimba Mandau Lestari, Siak Regency, Riau, to replace the less effective manual monitoring approach. Testing results showed that the use of a Low Noise Amplifier (LNA) improved signal quality, achieving an average RSSI of -97.6 dBm and a Delivery Success Rate of 100%, with a delay of up to 12.36 seconds.
