Abstract

Dukungan fasilitas komputer atau alat bantu kegiatan hands-on lainnya jelas dibutuhkan dalam membekali keterampilan praktis bidang komputasi dan teknologi informasi kepada peserta didik. Dalam penelitian ini, diusulkan suatu portable server berbasis single board computer (SBC) dan teknologi WiFi-direct untuk menjadi alat bantu pembelajaran dengan beberapa karakteristik: (a) portable secara fisik, (b) rendah biaya, (c) dapat diakses dari berbagai platform perangkat pengguna, dan (d) tidak mengandalkan ketersediaan koneksi internet. Fokus penelitian ini adalah rancang bangun portable server tersebut dan pengujian kinerjanya ketika digunakan dalam pembelajaran hands-on. Server yang dibangun berhasil diakses oleh beberapa perangkat berbeda (dicobakan hingga 4 platform perangkat yang berbeda) baik secara terpisah maupun secara bersamaan. Pengujian kinerja yang dilakukan mencakup pengujian waktu respon sistem dan pengujian penggunaan sumber daya komputasi server. Pengujian waktu respon sistem dilakukan untuk mengetahui berapa lama waktu yang dibutuhkan dan harus dialokasikan untuk persiapan server dalam kerangka waktu kegiatan pembelajaran. Hasil yang didapatkan cukup baik, yaitu total waktu terlama sejak server booting sampai pengguna berhasil login adalah 2 menit 45 detik. Pengujian penggunaan sumber daya komputasi server pada paper kali ini difokuskan berupa baselining untuk mendapatkan gambaran penggunaan sumber daya server dalam kondisi beban minimum ketika hanya diakses oleh pengguna tunggal yang hanya mengakses satu tool pembelajaran saja. Baseline penggunaan sumberdaya komputasi server yang didapatkan meliputi penggunaan sumber daya CPU, memory dan network untuk beberapa skenario: akses melalui kabel UTP, akses melalui hotspot server, aktivitas remote shell, aktivitas remote desktop, dan akses suatu tool pembelajaran berbasis command line interface (CLI). Tindak lanjut yang diharapkan dari penelitian ini adalah pengujian waktu respon, pengujian beban, serta pengujian batas kemampuan server ketika diakses secara simultan oleh banyak pengguna yang mewakili lazimnya jumlah peserta suatu kelas.

Abstract

The community health centres, or commonly known as Puskesmas in Bahasa, are the backbone for Indonesia citizens in dealing with and fighting against the Covid-19 outbreak. They are the first responders and primary services that is closest to the community. Their healthcare professionals have a very important role as the front lines that identify the symptoms at the village level. It is mandatory that they use adequate personal protective equipment (PPE) when examining people's health. With the PPE, healthcare professionals remain protected from the risk of Covid-19 exposure. The lack of PPE availability sometimes makes many officers have to use any available materials as their protection. Addressing the lack of PPE availability in a Puskesmas of a suburban area like Bungus, the Department of Computer Systems, Universitas Andalas, decides to put some innovations into practice. In this community service activity, certain PPE and sterilization tool-aids are designed and developed to protect healthcare professionals from the risk of Covid-19 exposure. Some of the types of equipment provided for the centre are portable sterilization poles, hand sanitizer tool-aids that can be used without having to be touched by hands, face shield in the form of a face-covered hat using mica material that can be reused by washing or wiping it using a disinfectant, and hijack-masks made from spun-bond fabric that is comfortable and waterproof.

Abstract

Emotions influence individual behavior and there is no emotional experience that has a stronger influence than stress. Prolonged stress has a direct negative influence on physical and emotional conditions. For that reason, it is important to know a person's mental stress state, so that further action can be taken later, so as not to have a serious impact on physical and mental health. In this study, the photoplethysmograph (PPG) approach is used to recognize mental stress conditions based on Heart Rate Variability (HRV) frequency domain analysis. In this study stress was identified by SVM classifier using LF, HF and LF / HF Ratio from HRV frequency domain analysis. The LF results were increased in mild stress conditions, HF increased in conditions of mild stress and medium stress and the LF / HF Ratio slowly increased from mild stress to severe stress. The training data obtained 80 data with 95% mild stress accuracy from 19 data, medium stress accuracy 96% from 49 data and 99% severe stress accuracy with 12 data.

Abstract

This study aims to create a system to detect vehicle speed in the School Safe Zone area using Mini PC based with Computer Vision technology and Image Processing techniques. This research, was hoped for the drivers will more discipline in driving, so can create safe and comfortable traffic in the School Safe Zone area. This system was made using a camera module to take video of the track, Raspberry Pi was used as the main device for detection and speed calculation. Every vehicle which crossed the zone would be detected and tracked to follow every vehicle movement, then was conducted a process of saving the center point of the vehicle object based on the initial detection line. Finally, calculated the vehicle speed based on the distance and time the vehicle moved on the frame which was set based on the detection line. The results of the vehicle speed would be displayed on the LCD and the output was in the form of a sound from the speaker as a warning for drivers whose vehicle speed exceeds 25 km / hour. Based on results of this research, the system was capable for work well in detecting and getting the speed results of passing vehicles. However, for direct implementation the devices in this system are inadequate for video processing, so that the response time and accuracy level was obtained by the system did not match for actual conditions.

Abstract

Tantrums are outbursts of anger and they can occur at any age. An attitude tantrum or what is commonly referred to as a temper tantrum is a child's outburst of anger that often occurs when a child shows negative behavior. Emotional outbursts of tantrums that occur in children with autism are not only to seek the attention of adults, but also as an outlet for a child's feelings for parents and those around him on a whim or feeling he is feeling, but the child cannot convey it. For this reason, researchers propose a system for detecting early symptoms of tantrums in children with autism through facial expressions with CNN. The CNN method is one of the deep learning methods that can be used to recognize and classify an object in a digital image. Then the preprocessing process is carried out using labeling on the data. Then the CNN architecture is designed with input containing 48x48x1 neurons. The data was then trained using 357 epochs with an accuracy rate of 72.67%%. Then tested using test data for children with autism to get an average accuracy value of 72.67%%.

Abstract

Security is very important necessary for everyone, one of that security’s needed is the savety of valuables both publicly and more especially at home. Because many of thieves who come direcly to the house, the door was forced open, ande forgot to close the door, the thefs cases increased. Therefore the system can detect movement in front of the door using a PIR sensor design, gives a warning when the door is forced open and can open or close the door automatically. This research uses the Telegram Bot to send orders and receive notifications in the form of text or images. The PIR sensor will give notification when a movement is detected in front of the door, onece detectedit will turn on the LED light and take a picture of the movement, a warning from the system in the form of buzzer. It will also serve as a warning when the door is forced open. When the user enters the open command via Telegram Bot, the door will open and close by itself. The error of the tested system is 0%, all components can work as expected.
