Abstract

The Covid-19 pandemic requires schools to divert their learning in their respective homes simultaneously with government regulations related to large-scale social access (PSBB) which aim to avoid crowds and add new clusters in the educational environment. This is a challenge for schools that do not yet have a bold learning platform and for teachers who still cannot use technology to provide their learning boldly. The web-based e-learning platform is expected to be able to assist teachers and students in carrying out learning without any technical guidance on its use. By using Rapid Application Development (RAD) in its design, it is hoped that it can produce an e-learning platform that is easy to use by teachers and students from SMAN ABC. This research is only up to the Design Workshop.

Abstract

The purpose of this study is to build a data model for scheduling lectures at the Informatics Engineering Study Program, Faculty of Engineering, Muria Kudus University uses ontology as part of the implementation of semantic web technology. System built based on existing schedule data in the Informatics Engineering Study Program, such as data days, courses, credits, space and time stored in RDF / OWL format. The use of a lot of data with different storage formats becomes problems in finding valid information. To overcome this, it is necessary a system that can provide complete information is needed, namely with using semantic web technology. The semantic web is used to understand meaning of a word and concept, because it builds interconnected resources. Semantic web implementation is built using the ontology approach applied to RDF/OWL format. The results of this study are improving the ability of computers to search for more informationrich lecture schedules in the Informatics Engineering Study Program.

Abstract

This study aims to apply twitter bootstrap in an e-commerce web so that the web display becomes more responsive, that is, it can provide a display according to the device used to access the web. The object of this research is the Putra Reban Store in Kendal which markets local art equipment and supplies, especially masks.The system development method used in this research is the Scrum method with stages including product backlog, sprint backlog, sprint and working increment. This method was chosen because it can save system development time and can transform a business that is difficult to measure into one that is easy to develop. The system is designed with 2 actors, namely admin and customer. Admin has access rights to manage product data, customer data, and order data, while customers have the right to access product data and make order transactions.With this developed system, it is easier for Putra Reban Stores to market their products because product descriptions and product availability stocks can be informed more easily and accurately. With complete and accurate product information, it will also be easier for customers to make transactions.

Abstract

Aset yang dikelola oleh sebuah instansi bisa berupa peralatan yang mempunyai batas umur pakai, jika perawatannya tidak tepat maka akan berakibat pada pemakaian yang tidak maksimal. Perawatan bisa berupa servis rutin dan servis ketika terjadi kerusakan, perawatan dilakukan oleh tenaga teknisi. Kemampuan dari setiap teknisi belum tentu sama, pemberian tugas berdasarkan pada unsur subyektivitas tidak akan mampu memberikan layanan yang baik pada perbaikan yang diminta oleh masing-masing divisi, karena pemilihan teknisi berdasarkan subyektivitas tersebut belum tentu didapatkan teknisi yang memiliki keahlian sesuai dengan tingkat kerusakan alat.   Perlu sebuah upaya obyektif untuk mendukung keputusan dalam mereferensikan teknisi pada sebuah proses perbaikan dengan menggunakan metode K-Nearest Neigbor

Abstract

Penilaian secara periodik terhadap driver perlu dilakukan, untuk mengevaluasi kinerja. Pelaksanaan evaluasi membutuhkan waktu sehingga evaluasi sering dilakukan ketika terjadi keluhan dari penumpang, memberikan efek perubahan yang sifatnya sementara juga, setelah keluhan teratasi maka driver maupun pimpinan divisi transportasi menganggap tidak akan terjadi lagi kejadian yang sama. Bentuk evaluasi seperti di atas seringkali hanya  dilakukan terhadap driver yang dikeluhkan penumpang.   Penilaian kinerja yang termodel dan menyeluruh terhadap semua driver, yang sifatnya periodik dengan Sistem Pendukung Keputusan berbasis Profile Matching mampu meminimalisir kejadikan yang dikeluhkan penumpang..

Abstract

Broiler Chicken Feed System is a tool that is implemented using microcontroller technology. The focus of technology in industry 4.0 is that all devices can be controlled and monitored remotely, as long as they are connected to a network. In accordance with this vision, this technology makes it easier for farmers to feed chickens that were originally still using manual labor, then made automatically by implementing microcontroller technology consisting of SIM800L, Arduino, servo motors, and ultrasonic sensors. By using two ultrasonic sensors that are placed to enter orders and provide information about the stock of chicken feed this technology can work well. The focus of this technology is that it can be used for remote monitoring. Not only that, this technology can also send notifications to the farmer's smartphone to show the condition of the chicken feed stock that is still available. By applying this technology, chicken farmers can combine and feed their chickens from anywhere.

Abstract

Social distancing is an effort to prevent the spread of the coronavirus. Several systems for monitoring social distancing have been developed. People detection is an essential step in implementing a social distancing system. Failure to detect people causes the social distancing system to be inaccurate. Two people who communicate cannot occur violations of social distancing because one person is not detected. Therefore, we propose a precise person detection method for the social distancing system. The proposed social distancing system uses the YOLOv3 method for people detection and Euclidean Distance for measuring the distance of social distancing. YOLOv3 can detect people's objects precisely, even people who are caught small by the camera. Experiments on two outdoor video datasets result in an F1 value of more than 0.8. This proposed system can serve as a reference for future social distancing research.

Abstract

The Ministry of Education and Culture (Kemendikbud) issued Circular Letter Number 15 of 2020 concerning Guidelines for Organizing Learning from Home in an Emergency for the Spread of Covid-19. This causes the learning process that should be done face-to-face, being changed to online. Students must study from home and carry out the online thesis guidance process. Some of the difficulties experienced by students during direct mentoring, namely the difficulty of meeting lecturers who are busy teaching or doing assignments from institutions, besides that students who come from outside the city have to go back and forth just to meet the supervisor.. One of the ways to solve this problem is by applying technology.   Currently there is web technology that can be used to easily develop applications, namely the concept of a framework approach. With the existence of an online-based application which is the role of current technological developments, it will make the thesis guidance process carried out by lecturers and students more flexible. Students are able to carry out the guidance process anywhere and anytime.
