Abstract

The graduation rate for each student is different, timely and not on time. What can be an obstacle is if there are many students who graduate not on time. Based on data in 2018 on the official website of the Faculty of Computer Science, Universitas Brawijaya, the average student admission of Information Systems every year is approximately 227 students, while for the average student graduating annually around 134 students. So based on these data, an application is needed that is able to help decision makers to predict earlier students who have the potential to pass on time so that further action can be given. The process of predicting the timeliness of graduating students will be done using the Naive Bayes algorithm. The system implementation will utilize the Laravel framework and Weka simple CLI. The output generated from the system is in the form of a dashboard visualization with a chart containing graduation information, a form to create a model, information from the model that has been made, and a form that can be used by the Head of the SI Department to predict the timeliness of graduating students. The results of the evaluation and validation of the Naive Bayes algorithm resulted in an accuracy value of 88.6076% and an AUC of 0.9558. The results of testing the system using black-box testing shows that the system is valid according to defined requirements. While for usability testing with the System Usability Scale produces a value of 67.5 which is classified as an Adjective rating Good.

Abstract

Fires often occur in the area of housing, Office space or in the Woods. The emergence of the fires themselves often leave casualties is not a little. Fire occurrence process itself can develop quickly or slowly depending on various factors such as the typically temperature, wind direction or weather based on material to burn. The issue was made of various fire alarm systems that are usually placed on building large and function gives a warning if the fire is large enough or usually the alarm will also be activated manually but the system does not tell you the location of the occurrence of fires. Based on the problems researchers make fire with point detection system sensor LM35 and flame sensor using algorithms K-Nearest Neighbor and a microcontroller, Arduino Mega as data processing. The workings of this system with sensor LM35 temperature detected on duty around the room and the sensor detects flame flame candles. If there is a fire then the system will process the calculation by the method of classification results obtained so KNN are used as the end result of this system. After the research is done, the results obtained from testing system has the accuracy of 80.55% and for process calculation of classification are obtained for 1428.83 ms.

Abstract

The Medium Voltage Network Reconfiguration Work Plan Program is one of the work plan programs in the investment budget worksheet. This work plan program is used to rearrange the medium voltage network by dividing a load of electricity distribution facilities with other electricity distribution facilities. The documentation of the proposed work plan program now still uses several separated documents. It becomes ineffective task since there will be duplicated documents for the same proposal due to revisions. Changes in construction prices also cause changes in the proposed data such that manual changes need to be made for each proposal. This will take a long time process. Customer Service Unit (ULP) at this time also can't know the progress of the proposal that has been submitted. The investment budget worksheet system for the medium voltage network reconfiguration work plan program was developed to solve these problems. This system development was done in a web-based platform. Such development was done by using the Waterfall development model and an object-oriented approach. The system has been tested through several testing strategies, namely unit testing, integration testing, and validation testing. The unit and integration testings were performed by using white-box testing technique, while the validation testing were done using black-box testing technique.

Abstract

Roads are infrastructure that have an important role to support land transportation and support equitable development in an area., therefore road conditions must always be in good condition. In conducting monitoring, a survey is needed to determine the feasibility of road conditions. One survey method used is the International Roughness Index (IRI). PT. Hirfi Studio is a technical consultant company in Malang that provides transportation infrastructure survey services. PT. Hirfi Studio conducts surveys using direct visual observation method and then recorded manually on a survey form to be processed and converted into an IRI scale. The main tool used in conducting surveys are GPS, cameras and worksheets. The weakness of that processes are survey data in the paper form vulnerable to loss and damage, and processing data from the digitization of data to making maps takes a long time. Therefore, it is necessary to develop an automation survey on road condition using smart phone sensors to assist in conducting surveys. System development is done using software development life cycle (SDLC) waterfall model with object-oriented approach. The implementation of the application applies the model-view-controller (MVC) pattern in Codeigniter framework using HTML, PHP, CSS and Javascript programming language and uses database management system (DBMS) MySQL. In the testing phase, the unit testing value is 100% from 12 test cases, 100% validation of 46 test cases, and compatibility testing shows that the application can run on all desktop and smartphone web browsers.

Abstract

Home security system is an important and mandatory thing that must be considered by every homeowner. Therefore, one solution that is widely used is to use CCTV to monitor the state of the home environment, but the current CCTV data stored is in the form of video which usually requires a large enough storage space of course it is less efficient in the use of storage space. The solution is to build a CCTV with a system that uses image files as a data format, in addition to more efficient storage of image data formats, it also makes the system work less so that it is lower power than video formats. Therefore in this research, a CCTV system based on Wireless Sensor Network with Motion Detection System for Home Security consists of 3 sensor nodes and a sink node. When the sensor node detects a movement of the system will send a notification to the homeowner and take pictures automatically then send it to the sink node. Homeowners will receive a URL address to access the image file. This system communicates using a WiFi network and consists of several components, namely: 3 ESP32 microcontrollers and a camera, 3 SR501 PIR (Passive InfraRed) sensors and a Raspberry Pi Model B. Based on the results of trials on this system it was found that the system can detect movement by effective in the range of 1 meter to 6 meters from moving objects. Each sensor node is able to send images to the sink node. The system is able to send notifications to homeowners and the system can provide a URL address so that image files can be accessed remotely.

Abstract

This sponsorship and partnership search engine was initially designed to bring companies and communities together. Sponsorship is a form of financial support from a company to ensure the success of an upcoming event, which in return will help the company to gain awareness and good image through the event. However, there are many obstacles that communities often encounter. One being the difficulties in finding accurate information of the sponsor. As for the company, in order to settle into an agreement to support an event, must acquire detailed information regarding the event itself and take many factors into consideration. To solve the issues, a website is built to showcase not only a list of sponsors, but also list of events that might need one. That way, the product offer as well as the aim of the event will be shown clearly. This research is conducted using Object Oriented approach, with MVC [Model - View - Controller] design protocol, and will be developed using the waterfall methode. The sytem development will be conducted through MySQL database. The research has been succesfully tested through unit test, integrated test, validation test, and compatibility test. The entire research has been successfully conducted according to the previous design and analysis.
