Abstract

The creation of an Internet of Things-based motor vehicle early prevetion tool (Sitinjau Lauik Case Study) has been completed.. The aim of this research is to develop a tool to minimize accidents caused by human physiological factors such as fatigue and drowsiness. This device utilizes the MPU 6050 sensor, pulse heart sensor, buzzer, vibration motor, GPS, Arduino Uno and Wemos D1 Mini. The research method began with the construction of the device and the permance testing of the system. The results indicate that the system of this device can detect drowsiness or fatigue by measuring the heart rate at less than 70 bpm using the pulse heart sensor and detecting head movements using the MPU 6050 sensor, where the X- axis angle is > 29,23 ° < - 30,63 ° and the Y-axis angle is > 29,33° < -20,12°. When drowsiness is detected, the device sends notifications via the Telegram application containing the driver’s condition, heart rate, andlocation through a Google Maps link. Subsequently, when the driver is drowsy, the buzzer sounds to provide a warning and the vibration motor provides vibration to give a sensory wake-up signal to the driver, helping to awaken them from a drowsy state. Overall, the device functions effectively.

Abstract

Gunung Talang, Twin Lake, Gumanti Valley, Hiliran Gumanti and Pantai Cermin sub-districts in Solok Regency, which are dominated by hills and trees, are the cause of unstable signal quality, causing complaints from the public regarding this. So this study is to determine the network quality in Gunung Talang District, Twin Lakes, Gumanti Valley, Hiliran Gumanti, and Pantai Cermin on Telkomsel, XL and Indosat Operators. Checking is carried out using the drive test method  using TEMS Pocket on 2G and 4G networks. The quality of the 2G network from the measurement results was obtained for RxLevel all operators was bad and for RxQual was good except for Telkomsel operators.Meanwhile,on the 4G network, measurement results for RSRP and SINR for all operators are bad. Some areas that have problems are recommended for optimization, site passenger  and site addition. All of this happens because  of obstacles in the form of hills, cliffs, and tall trees at some point. From the results of the study, the quality of the Telkomsel operator's 4G network has an RSRP value of 46.16% and SINR of 61.06%. XL operators have an RSRP value of 42.7% and SINR which is 60.74%.Meanwhile, Indosat Ooredoo has an RSRP value of 43.2% and SINR of 74.6%. As for the 2G network, the quality of Telkomsel's 2G network operator has an RxLevel value of 47.8% and RxQual of 89.49%. XL operators have an RxLevel value of 58.34% and RxQual of 77.62%.Meanwhile,Indosat Ooredoo has an RxLevel value of 46.16% and RxQual is 80.56%.

Abstract

Rural areas are indicated to be still difficult to reach by 4G signals due to diverse topographical conditions and uneven landscapes, especially hilly areas that weaken the signal reception level in this region. To make the 4G signal accessible in this area, a repeater in the form of an antenna is needed to strengthen the signal. In this study, a yagi antenna is designed with three reflector elements at a working frequency of 1800 Mhz 4G LTE, expected to produce a minimum gain of 12 dBi and a more focused antenna radiation to strengthen the 4G signal in rural areas. The antenna design was simulated using CST Studio Suite software, with optimized simulation results yielding a return loss of -22 dB, VSWR 1.167, and gain 12.40 dBi. From the measurements obtained, the yagi antenna with three reflector elements works well at a frequency of 1800 Mhz, with a return loss of -34.77 dB, VSWR 1.065, gain 12.96 dBi, and unidirectional radiation. With the optimal antenna parameters and the addition of three reflector elements, it's possible to increase the gain value, even though the gain increase isn't substantial, and it narrows the HPBW (Half Power BeamWidth) value. Moreover, testing the yagi antenna at 3 different distances demonstrated that the resulting gain value can enhance 4G signal speed in rural areas

Abstract

The public truly needs technological advancements, particularly internet networks, in order to access information such as phone, data, and video services, all of which are growing in volume. This requirement also holds true for isolated places without internet connectivity, like Nagari Rangkiang Luluih. The primary barrier to building telecommunications infrastructure, such as Base Transceiver Stations (BTS), which are more expensive than BTS, is geographic conditions. For isolated Indonesian locations without access to a telecommunications network, such as Rangkiang Luluih, VSAT technology offers a practical alternative in the form of dependable and constant internet connections. VSAT provides greater coverage and increased dependability by acting as a repeater for satellite communications. greater than BTS, particularly in regions with challenging topography. When compared to BTS technology, the design findings demonstrate that VSAT is a more cost-effective and efficient option. Planning the VSAT network design in Nagari Rangkiang Luluih yielded optimal parameter values for internet access services in the Tigo Lurah District, Solok Regency, and the hilly, forested, and valleyous remote areas. These values included an average delay of 34.08 ms, a throughput of 379.66 bps, a jitter of 10.58 ms, and a packet loss of 0%.

Abstract

Materi fisika pada tingkat SMA yang terkait dengan ilmu elektro adalah getaran, gelombang dan bunyi; listrik statis, listrik dinamis, energi dan daya listrik,kemagnetan, dan induksi magnet. Semua materi tersebut diajarkan dengan mengedepankan pelatihan kemampuan kognitif berupa hafalan dan analisis dari siswa. Dimana siswa banyak mengingat rumus dan latihan soal mengenai materi terkait. Dengan membuat sebuah rangkaian radio FM sederhana bisa memberikan pemahaman kognitif yang terkait aplikasi ilmu bagi siswa mengenai apa tujuan dan manfaat dari materi yang sedang dipelajari. Pemahamahan getaran dan gelombang akan ditunjukkan dengan mikrofon yang dapat merubah getaran suara menjadi energi listrik yang merupakan listrik dinamis. Pada aplikasinya listrik dapat dibangkitkan dengan menggunakan lilitan dan kapasitor. Dan dengan sifat listrik dan magnet memungkinkan sinyal listrik dirubah menjadi gelombang elektromagnetik dan sebaliknya dirubah dari gelombang elektromagnetik menjadi energi listrik. Sehingga pada akhirnya siswa mendapat gambar bahwa energi suara dapat di transmisikan melalui gelombang radio. Diharapkan dengan bantuan rangkaian FM ini membuat siswa lebih tertarik mempelajari materi gelombang, kelistrikan dan kemagnetan dalam pelajaran fisika.
