Abstract

The Indonesian government through the Smart Indonesia Program provides cash assistance through the Smart Indonesia Card. The problem that occurs is that the selection process for KIP assistance recipients has not gone through the right procedure, resulting in social jealousy among students who should not be eligible to receive assistance but receive the KIP assistance funds. This is because some students have relatives from school officials so that student data can be manipulated. Therefore, a decision support system is needed that is able to select the eligibility of students receiving KIP funds quickly and accurately by using the Preference Selection Index (PSI) method. The Preference Selection Index (PSI) method which in line performs calculations on the matrix multiplication between criteria that have a weighted value of each alternative so as to produce a PSI value which will be the final result in determining the eligibility of students to receive KIP assistance funds. The resulting impact is the selection of students who really have the eligibility requirements to get KIP funding assistance.

Abstract

The use of digital images is increasing because of the advantages possessed by digital images, the lighting quality in digital images that are too dark or too bright. Where this noise is usually obtained from the image digitization process. Noise in digital image processing is a disturbance caused by deviating digital data received by the recipient of image data. The elimination of noise in the image is one of the most important parts in image processing. In the process, the images is on. The input is converted into 3x3 matrix then the process uses the contrast streching method for fix the noise from the image. In this study using the Contrast Stretching method and the Convolution method so that the objects and backgrounds in an image can be recognized more clearly

Abstract

COVID 19 disease caused by a corona virus called SARSCo V2 (severe acute respiratory syndrome corona virus 2) was first discovered in China, precisely in the city of Wuhan, December 2019. The spread of this virus is very fast, and one of the ways this virus can spread is through objects around. For this reason, users of online shopping applications are not necessarily packages that arrive at the destination address free from the corona virus. To sterilize online shopping packages, they can be sterilized by spraying disinfectant. Spraying disinfectants can be done manually or automatically, automatic spraying being an efficient and practical way to save energy. The manufacture of this automatic disinfectant sprayer uses an Arduino Uno microcontroller as a tool control system, an FC-51 infrared sensor as an object detector, a mini water pump to drain disinfectant, a door lock for the security system, and other components. By using these components and software that supports the running of the tool, the disinfectant spraying tool can work automatically. This tool is box-shaped and has two sides of the door, the first door is for the door to enter the package and the second door is for the homeowner to pick up the package.

Abstract

During the current pandemic, keep a sound safe framework. also, obviously to know it all we need to actually take a look at it. The heart is one of the fundamental organs possessed by people whose capacity is to siphon blood all through the body. Pulse Beats Per Minute (BPM) is a boundary to decide the state of the heart and the way of deciding the state of the heart is to know the recurrence of the heartbeat. What's more, with the assistance of a temperature sensor, it will be more useful to know the state of our body. This body condition observing apparatus is planned dependent on NodeMCU ESP8266, temperature sensors DS18B20 and MAX30102 to recognize pulse. This examination was led to make it simpler for us people to control the soundness of our bodies at whatever point and any place we need. The pulse and internal heat level information from the observing device will be shown on the OLED LCD and the outcomes from the sensors will be shown on the OLED LCD and furthermore a sound notice that contains data regarding if your body is in acceptable condition dependent on the consequences of the two sensors.

Abstract

College ranking is the main thing used as a basis to attract prospective new students. Prospective new students will generally look for related information from which universities are the best to choose in the future. In the ranking of universities based on the official page of the Ministry of Research, Technology and Higher Education, the ranking of universities, both public and private, can be a reference for recruiting prospective students. The better the college ranking, the more attractive prospective new students are. To determine the ranking of a university, a decision support system is needed. There are many methods available from the decision support system, but in this study, the author will use the VIKOR method (Visekriterijumsko Kompromisno Rangiranje), which is part of the MCDM (Multi-Criteria Decision Making), as a solution to these problems. The VIKOR method is a multi-criteria optimization method that can be used on fairly complex systems. In this study, the sample data used came from 10 universities in the city of Medan, where the initials of each naming were colleges A to J. From the results of research analysis using the VIKOR method, the ranking results were as follows, where college B got the first rank with the lowest score of 0. Then the second rank was college G and in the third rank was college H with each score of 0.248211396 and 0.304702661. For the fourth, fifth, sixth, seventh to tenth ranks, they are sorted from colleges A, I, C, E, F, D, and J.

Abstract

Since the COVID-19 pandemic, every learning has to be done online, even though vocational institutions require more practice. So far, students are only given video tutorials on practical learning methods that are felt to be less effective, because students cannot directly touch the items, so it is still not optimal. This condition also makes the motivation and interest and curiosity of students in learning decrease. These situations and conditions require teachers to think creatively and innovatively in designing and implementing learning to take place effectively. One way that can be done by teachers by utilizing the latest technologies that are increasingly sophisticated as learning media. Augmented Reality technology is an alternative solution that can be used as a learning medium. Augmented Reality is an attempt to combine the real world and the virtual world created through a computer so that the boundary between the two becomes very thin. The results of this study are to produce an application that runs on the Android platform by implementing Augmented Reality as a support in learning media activities in the Audio Video Technical Vocational High School. Keywords:  Augmented Reality, Android, COVID-19, Learning Media

Abstract

Ilmu Pengetahuan dan Teknologi atau biasa kita kenal dengan sebutan IPTEK saat ini sangat menguasai dunia. Hampir semua kegiatan yang dilakukan oleh manusia setiap harinya memerlukan IPTEK. Salah satu pekerjaan yang rutin dilakukan bagi pemelihara ikan hias adalah mengganti air akuarium. Semakin lama air pada akuarium maka semakin kurang kejernihannya dan secara berkala berubah menjadi air yang keruh. Air yang keruh dapat mempengaruhi perkembangan fisik ikan. Permasalahan timbul apabila pemilik ikan lupa ataupun meninggalkan rumah dalam waktu yang cukup lama dan tidak dapat mengganti air akuarium secara rutin. Maka dari itu penulis ingin membuat sebuah sistem yang dapat mengganti air akuarium secara otomatis. Sistem  bekerja dengan dua acara. Pertama apabila air pada akuarium sudah mengalami kekeruhan dan mencapai batas yang ditentukan maka air akan diganti. Kedua penulis akan membuat sistem secara otomatis melakukan pergantian air satu kali dalam satu minggu. Setiap pergantian air yang telah dilakukan akan diberitahu kepada pemilik ikan melalui SMS (Short Message Service) bahwasanya air telah selesai diganti. Sensor turbidity bekerja  dalam mengecek kekeruhan air dan proses pergantian air berjalan dengan lancar. Pergantian air baru secara otomatis dalam waktu satu kali dalam seminggu berhasil dilakukan. Modul GSM SIM800L mengirim SMS ke Smartphone memberi informasi bahwasanya air telah diganti dengan air baru.
