The problem that occurs is that the increasing number of vehicle users has an impact on the increase in the need for parking available on campus In existing conditions, it is not enough to accommodate the number of vehicles, especially on certain lecture days and when there are campus activities that invite many vehicles to enter, such as during graduation events or other activities. The characteristic analysis of car parking is that 919,505 m² can produce 38 SRP, while for a motorcycle parking area which has an area of 834.65 m² it can produce 401 SRP. The number of parking space requirement for both four-wheeled and two-wheeled vehicles in the next 10 years has increased every year with the results of the analysis of the number of students are 15.4597 people in 2030 from 8744 people in 2020 so that the need for vehicle parking spaces in the next 10 years will reach 65 SRP with A capacity of 39 SRP is available for cars and 723 SRP with a current parking capacity of 405 SRP for two-wheeled vehicles.</p> Rifky Aldila Primasworo Rifky Aldila Primasworo Andy Kristafi Arifianto Andy Kristafi Arifianto Karolina Nay Karolina Nay Copyright (c) 2021 Jurnal Qua Teknika https://creativecommons.org/licenses/by-sa/4.0 2021-09-01 2021-09-01 11 2 22 31 SISTEM PEMANTAUAN PENGGUNAAN PROTOKOL KESEHATAN COVID-19 MENGGUNAKAN METODE HAAR CASCADE DAN NEURAL NETWORK https://ejournal.unisbablitar.ac.id/index.php/qua/article/view/1686 <p><strong>SISTEM PEMANTAUAN PENGGUNAAN PROTOKOL KESEHATAN COVID-19 MENGGUNAKAN METODE HAAR CASCADE DAN NEURAL NETWORK</strong></p> <p>COVID-19 is the biggest health problem that occurs in the world today, this virus with its rapid spread and strong resistance has claimed many lives. One way to prevent the rapid spread of this virus is to break the chain of its spread, and always complying with the COVID-19 Health protocol. Some examples of the COVID-19 Health Protocol are the use of masks, normal body temperature, always washing hands, and others. However, public awareness of compliance is still very low, so the COVID-19 pandemic has not ended until now. The best solution at this time is to monitor and ensure the use of the COVID-19 Health protocol. However, with the advancement of technology now and minimizing human contact, the author created a MONITORING SYSTEM FOR THE USE OF COVID-19 HEALTH PROTOCOL USING HAAR CASCADE AND NEURAL NETWORK METHODS that use machine learning technology so that there will be no contact between humans. With this tool, the author hopes that it can reduce the spread of COVID-19 and can end it so that all people can return to normal activities without being disturbed by virus disturbances.</p> Alif Yudhistira Putra Bayu Suroso Sholihin Copyright (c) 2021 Jurnal Qua Teknika https://creativecommons.org/licenses/by-sa/4.0 2021-09-01 2021-09-01 11 2 32 46 RANCANG BANGUN SISTEM KAMERA PEREKAM PORTABLE MENGGUNAKAN RASPBERRY PI TERINTEGRASI DENGAN SERVER BERBASIS INTERNET OF THINGS https://ejournal.unisbablitar.ac.id/index.php/qua/article/view/1617 <p>Camera recorders in general will continue to record continuously without stopping and this will take up storage space. This is deemed less effective because of its limited capacity and also in terms of security, the recorded information is very vulnerable. Therefore, in this study, a portable recording camera system was designed using multi sensors and integrated raspberrypi with the server and then the recording results will automatically be sent to the server and forwarded to the user's email. This portable recording system uses a PIR sensor (Passive Infrared Receiver) HC-SR501, Raspberry Pi 3 B plus, Infrared led light, Pi camera, KY-037 sound sensor, SMTP Server (Simple Mail Transfer Protocol). When the PIR sensor detects movement or the KY-037 sound sensor detects sound, it will be processed by the Raspberry Pi and then the Pi camera will automatically perform the recording process periodically. When finished, the recording results will be sent directly to the user's email via the SMPT (Simple Mail Transfer Protocol) server provided by Google. All processes in this tool system work completely automatically.</p> ABI DZAR AL GIFARRY Abdul Rakhman Suroso Copyright (c) 2021 Jurnal Qua Teknika https://creativecommons.org/licenses/by-sa/4.0 2021-09-06 2021-09-06 11 2 47 57 10.35457/quateknika.v11i2.1617 REDESAIN SISTEM DRAINASE DI KAWASAN PASAR LAWANG KECAMATAN LAWANG KABUPATEN MALANG https://ejournal.unisbablitar.ac.id/index.php/qua/article/view/1694 <p>Drainase mempunyai pengertian mengalirkan, menguras, membuang, atau mengalihkan air. Secara umum drainase dapat didefinisikan sebagai serangkaian bangunan air yang berfungsi untuk mengurangi atau membuang kelebihan air dari suatu kawasan atau lahan, sehingga lahan dapat difungsikan secara optimal. Tujuan dari penelitian ini adalah merencanakan ulang jaringan drainase di kawasan Pasar Lawang Kabupaten Malang.

Begitupun juga dengan atap baja yang mengalami kerobohan, salah satu faktor penyebabnya ialah perencanaan struktur yang kurang matang. Pada gedung pertanahan berada di jalan Manukwari, Satreyan, Kecamatan Kanigora, Kabupaten Blitar merupakan gedung dua lantai dengan struktur bangunan dari beton bertulang dan untuk struktur rangka atap dari baja WF.</p> <p>Penelitian ini dilakukan untuk mengetahui hasil analisa perhitungan struktur rangka atap baja dan beton bertulang. Metode yang digunakan pada penelitian ini yakni <em>software </em>SAP 2000 yang mengacu pada SNI 1729:2015 tentang Spesifikasi untuk Bangunan Gedung Baja Struktural, SNI 2847:2013 tentang Persyaratan Beton Struktural Untuk Bangunan Gedung, dan SNI 1726:2012 tentang Tata Cara Perencanaan Ketahanan Gempa untuk Struktur Bangunan Gedung dan Non Gedung. Permodelan bangunan gedung pertanahan Kabupaten Blitar menggunakan SAP2000 tergolong aman karena masih mampu menahan beban yang telah diberikan. Pada perhitungan atap menggunakan SNI 1729:2015 tergolong aman karena tegangan dan lendutan yang terjadi kurang dari tegangan dan lendutan yang diijinkan. Pada perhitungan beton bertulang menggunakan SNI 2748:2013 sudah memenuhi syarat, karena lendutan total kurang dari lendutan ijin pada pelat, tahanan momen nominal lebih besar dari tahanan momen rencana pada balok dan kolom, kuat geser lebih besar daripada gaya aksial untuk pondasi.</p> Suci Lestari Nurjanah Nurjanah Nurjanah Nurjanah Copyright (c) 2021 Jurnal Qua Teknika https://creativecommons.org/licenses/by-sa/4.0 2021-09-01 2021-09-01 11 2 71 80 Perancangan Sistem Keamanan Pintar Kamera Night Vision Auto Color berbasis Raspberry PI https://ejournal.unisbablitar.ac.id/index.php/qua/article/view/1624 <p>In the rapid development of technology, there is a high crime rate. Therefore becomes very important. Many efforts can be made to secure a place and room, such as installing a security lock on the door or using a CCTV camera. But this is not enough to prevent crime from happening. Night Vision is the ability to see either in a biological or technological sense in a dark environment. Night vision capability can be achieved using two approaches, namely increasing the visible spectrum of the wave spectrum or increasing the ability to see low light intensities. Night vision has advantages and disadvantages, especially in conditions of very low light intensity. This technology has developed from time to time such as, there is the camera that uses sophisticated and modern electronic systems. Therefore, in this study, modern technology was designed with a smart security system that can be used to maintain home security or hunt at night.</p> Meutia Deli Rachmawati Abdul Rakhman Ade Silvia Handayani Copyright (c) 2021 Jurnal Qua Teknika https://creativecommons.org/licenses/by-sa/4.0 2021-09-01 2021-09-01 11 2 81 89 ANALISIS DAYA DUKUNG DAN PENURUNAN TIANG PANCANG MENGGUNAKAN DATA PDA TEST DAN PROGRAM PLAXIS PADA PEMBANGUNAN GEDUNG LABORATORIUM DAN KULIAH TERPADU UNIVERSITAS BORNEO TARAKAN https://ejournal.unisbablitar.ac.id/index.php/qua/article/view/1704 <p><em>The foundation is the structure of the lower part of a building that is directly related to the ground or part of the building that is located below the ground surface which has the function of bearing the load of other parts of the building above it.
