Abstract

Kindergarten teachers have been integrating technology into their teaching routine activities in Indonesia during the Covid-19 pandemic. When it comes to kindergartners, teachers cannot do much of anything remotely, particularly if pupils must sit and gaze at a computer for hours on end. Penguin Family Islamic Preschool Teacher will be prepared to create effective and efficient technology-based in this community project. Socialization and continuity guidance was the major activities. Qualitative analysis is employed for data analysis, data reduction, data presentation, and deriving conclusions. The result of discussions’ community services is 1) find online resources before you start student teaching; 2) invite parents to participate; 3) examine each child's activities; 4) enlist every student's participation; 5) help develop fine motor abilities; 6) learn about developmental-appropriate practice; 7) know your lesson plan; 8) educate socially; 9) observe the routine procedures. The conclusion is Kindergarteners are still learning to think critically, and they may lack group-work experience and struggle with self-discipline in an online environment. Simple procedures may require detailed instruction in the online environment.

Abstract

Salah satu hak pejalan kaki yang tidak boleh dilanggar oleh pengendara lain yang melintas yaitu zebra cross. Peraturan agar tidak berhenti di zebra cross sudah diatur dalam Undang-Undang Lalu Lintas dan Angkutan Jalan (UULAJ) Nomor 22 Tahun 2019 pasal 284 yang berbunyi “Setiap orang yang mengemudikan kendaraan bermotor dengan tidak mengutamakan keselamatan pejalan kaki atau pesepeda sebagaimana yang dimaksud dalam pasal 106 ayat (2)  dipidana kurungan paling lama 2 (dua) bulan dan denda sebesar Rp 500.000 (lima ratus ribu rupiah)”. Namun, masih banyak terdapat kendaraan bermotor yang melanggar aturan tersebut. Oleh karena itu, dalam penelitian ini, dibangun purwarupa sistem peringatan pengendara pelanggar zebra cross berbasis mikrokontroler ESP32-CAM, dengan menggunakan sensor ultrasonic untuk mendeteksi kendaraan. Ketika sensor mendeteksi kendaraan melebihi garis zebra cross yang ditentukan dan keadaaan lampu sedang berwarna merah, maka buzzer akan berbunyi sebagai peringatan pengendara yang melanggar garis zebra cross untuk mundur ke garis yang seharusnya. Selanjutnya, sistem akan meng-capture pelanggaran yang terjadi dan hasil tangkapan layarnya akan dikirimkan ke telegram sebagai bukti pelanggaran. Hasil dari penelitian ini, sensor ultrasonic mampu bekerja apabila terdapat kendaraan yang melintasi melewati garis batas sejauh 65,6 cm pada saat lampu berwarna merah. Pada saat terjadi pelanggaran, buzzer berbunyi menandakan pelanggaran terjadi dan kamera ESP32-CAM akan menangkap layar dan mengirimkan ke telegram sebagai bukti pelanggaran. Perhitungan waktu saat buzzer berbunyi sampai akhirnya gambar diterima dan ter-download sempurna ke telegram yaitu sebesar 5,2 – 7,99 detik.One of the rights of pedestrians that other passing motorists must not violate is zebra cross. Regulations so as not to stop at Zebra cross have been regulated in the Traffic and Road Transport Law (UULAJ) Number 22 of 2019 article 284, which reads, "Everyone who drives a motorized vehicle without prioritizing the safety of pedestrians or cyclists as referred to in article 106 paragraph (2) shall be sentenced to a maximum imprisonment of 2 (two) months and a fine of Rp. 500,000 (five hundred thousand rupiahs)”. However, many motorized vehicles stop at the zebra cross line, so it is difficult for pedestrians to cross the road because they are blocked by the car. Therefore, this study built a warning system for violators of zebra cross at red lights using the ESP32-CAM microcontroller, using ultrasonic sensors to detect vehicles. When the sensor detects the vehicle exceeds the specified zebra cross line and the sunlight is red, the buzzer will signal drivers who violate the Zebra cross line to back down to the appropriate queue. Next, the system will capture the violation, and the screenshot will be sent to the telegram as evidence of the breach. The results of this study show that ultrasonic sensors can work if vehicles cross the 65.6 cm boundary line when the light is red. When a violation occurs, a buzzer sounds indicating a violation has occurred, and the ESP32-CAM camera will capture the screen and send it to a telegram as evidence of a breach. The calculation of when the buzzer sounds until the image is finally received and downloaded perfectly to Telegram is 5.2 – 7.99 seconds. Misspellings and grammatical errors can affect your credibility. The same goes for misused commas and other types of punctuation. Not only will Grammarly underline these issues, but it will also show you how to write a sentence correctly.

Abstract

The progress of information and communication technology has resulted in a number of villages in Lingga Regency, Riau Islands still feeling the lack of public information due to signal limitations. One of the islands in the spotlight of the government is Pekajang Island. Economically the population of Pekajang Island interacts more with Bangka Island. A considerable distance and very minimal transportation facilities make Pekajang Island isolated. Therefore, to provide ICT services, a backhaul network is needed to support access to ICT services. In the study, a backhaul network of microwave transmission systems has been designed using frequency and diversity without diversity in the Riau archipelago. From the results of the design test using Pathloss 5.0 Simulator, the reliability value of the system that uses frequency diversity is 99.96879% and without diversity is 99.81417%. It can be concluded that the design results of a microwave transmission system using frequency diveristy are feasible to be applied because it has a system reliability value above the threshold based on ITU-R G.827 and F.1703 standards.Perancangan Jaringan Backhaul Sistem Transmisi Gelombang Mikro Digital Menggunakan Frequency Diversity dan Tanpa Diversity di Wilayah Kepulauan Riau

Abstract

In this study, the authors conducted an analysis of the quality of fiber optic network maintenance based on attenuation value and maintenance time using fuzzy Mamdani logic and simulated using Matlab software, to improve accuracy in drawing conclusions on maintaining quality. This study uses a quantitative method, in which the author obtains a summary of customer data from PT. Telkom Indonesia in a period of 4 months of observation from August to November 2021. In August there were 776 customers, in September there were 362 customers, in October there were 359 customers, and in November 445 customers who underwent Indihome fiber optic cable maintenance. The test results with the centroid method with an input Handling Time of 1.5 hours and an Attenuation of 15 dB, then the output Repair Quality is 5.5 or categorized as Good. The greater the attenuation value generated, the more time it takes to maintain the IndiHome internet network disturbance. This is due to the many technical maintenance of fiber optic cables carried out by technicians to adjust for damage/trouble in the field. It is expected that maintenance can be carried out routinely in order to avoid fatal internet disturbances on the customer's side, and maximize maintenance time according to the dosage determined by the company, which is less than 3 hours, taking into account the work performance of technicians and also the quality of maintenance.

Abstract

Metro ethernet is a data communication network owned by PT. Telkom Indonesia (Persero) through distribution channels, one of which is Open Shortest Path First (OSPF). As technology develops, IPv4 is used as the core addressing protocol for every communicating network device and has the responsibility of finding the route taken by packets to reach their destination. The problem that occurs in the data communication network is the absence of stable connectivity when there are links between cities experiencing downtime, resulting in several link congestion on the data packet path. To overcome the above problems, this study analyzed IPv4-based metro ethernet networks through the OSPF routing protocol using Graphical Network Simulator-3 (GNS-3). This study implements a failover system as a backup link in the event of a Jakarta-Bogor downlink. Based on the simulation and test results, the failover link shows a success status and functions to minimize network connection breakdowns. This is because the use of OSPF routing isOSPF routing canen the main link is down, so the path will be diverted via the backup link. QoS measurements using a single link obtained an average throughput of 195 Kbps, while dual links obtained an average throughput of 258 Kbps. This is because the distance from the source to the destination router is passed by more single links than dual links. Overall, the measurement shows that having a backup link can increase the stability of the data communication network connection when it is down and tested according to ETSI standards

Abstract

Along with the increasing demand for data networks, on the Java island network traffic, especially the Surabaya - Bangil link, the operator increases the channel capacity by modernizing DWDM (Dense Wavelength Division Multiplexing) technology in its transmission equipment. At that time, the DWDM technology was DWDM 6800 with a maximum capacity of one port that could only accommodate 10 Gbit/s, while using DWDM 9800, the maximum capacity of one port could accommodate up to 100 Gbit/s. Modernization of DWDM 6800 to DWDM 9800 technology uses the cross-connect method so that it does not require many costs and can be done within a short duration of time so that network performance can be adequately maintained. As a result, after modernization, the network has sufficient reserves to cover demand for the next few years.
