Abstract

The meeting is part of an important activity of the civitas employee in the Faculty of Computer Science, Brawijaya University to negotiate or resolve a problem that concerns the common interest, or development of the Faculty. The thing that must be ready in meeting activities is to make the meeting agenda and make minutes of the meeting. Making minutes of the results of this meeting is important, to help the accreditation process or re-accreditation of study programs. But in the implementation found several problems. The first problem is that the flow of meeting event making is still done conventionally when notifying the meeting agenda by sending SMS to prospective meeting participants. If there are prospective meeting participants who are unable to attend, the meeting participants do not know the contents of the meeting because the meeting material is not accepted by meeting participants who are unable to attend. The absence of a meeting remainder automatically leads to a meeting making prospective meeting participants sometimes forget about meetings. The second problem, namely when making minutes of the meeting is still carried out by each meeting participant. So that many minutes of meetings are not archived and lost. This makes it difficult for the Quality Assurance Unit (UJM) to find minutes of meetings to meet the needs of accreditation or re-accreditation of study programs. The third problem is that during the implementation of the meeting it still involves volunteers from the meeting participants to document the meeting activities with photos or videos, but often the photos or videos are not archived because of forgetfulness. The development of this software is web based using the waterfall method. This system provides a meeting event remainder feature that uses the Google Calendar API. This system uses the Logitech C525 webcam. Unit testing is performed using the white-box testing method 3 times. Validation testing using the black-box testing method 52 times resulted in 100% valid. Usability testing using the System Usability Scale method produces a score of 76.6 which is categorized as acceptable, so that the system meets user needs.

Abstract

The Center for Disability Study and Services Universitas Brawijaya (PSLD) conducts the mentoring process for students with disabilities every day. The scheduling process for mentoring students with disabilities is done by matching the disability student and volunteer schedules and verifying mentoring manually by looking at the mentoring logbook that has been filled out by volunteer students every week, which makes scheduling and verification of mentoring results ineffective because of the long and unknowable process the results directly. PSLD also does not yet have a reporting media that can be used to channel aspirations and complaints experienced by students so that students cannot report directly and cannot know the progress of the proposed report. Disability student assistance software is a system that has the goal of solving problems experienced by PSLD. The system can schedule the mentoring automatically based on the empty schedule of students, recap the mentoring process, and can provide functions for reporting. The system is developed through the stages of determining user needs, carrying out design, implementation, and testing. Testing is done using unit testing, validation, and compatibility with 100% valid results, and all functions can run well in several test environments.

Abstract

Malang City is one of the cities in East Java Province in Indonesia which has a lot of potential to be used as a tourist destination that can be visited by both domestic and foreign tourists. Data shows that the number of tourists visiting Malang is less than that of Batu City. The small number of tourists is caused by several factors. One of them is the lack of information related to tourist attractions in the city of Malang. To deal with these problems, a system development that aims to make it easier for tourists to get information about Malang city tourist destinations. In addition to finding information the system can also be used by tourists to submit proposed tourism locations that may not have been registered. Tourists can also provide value to tourist sites so that they can be used as a reference for tourism managers in building good tourism locations. The system was built using the Laravel framework which has more features than other frameworks and uses BotMan for the construction of chatbots in order to provide interactive information and with map support for more accurate location indicators. Testing is done by testing three aspects, namely unit testing, integration testing and validation testing in which all three tests produce a value of 100% valid. In compatibility testing we get the results that the system can run on 8 types of browsers. It is expected that this development will make it easier for tourists to access and obtain information about Malang City tourism.

Abstract

Children growth and development can increase significantly at the age of the first 1000 days of birth. Child growth and development can run optimally if the need for adequate nutritional intake. In early life, malnutrition (nutritional deficiencies) is very susceptible to occur, one of the consequences is stunting. Stunting is a condition when a baby has a lower height than a baby at his age, which is caused by poor parenting practices. The impact of a baby stunting can increase the risk of disease and even death, which will continue until the child is older. This application is formed by running 4 of the 5 stages of application development with the waterfall technique. Based on the results of the questionnaire, interviews with pediatricians and literature studies, 22 functional requirement were obtained and one non-functional requirement was obtained. Then the requirement modeling is done by using UML modeling which is used as a basis for implementing the design. The results of modeling are mapped into the PHP programming language, then tested with white box and black box techniques to test functional requirements and compatibility testing for non-functional testing. From the results of functional requirements's testing, obtained 100% valid results. While compatibility testing shows that the system is capable of running on 11 different search types.

Abstract

Posyandu is a Community-Based Health Effort (UKBM) organized from, by, for and with the people with the aim of prospering the community in the health sector. Those who manage posyandu consist of nutritionists, midwives and cadres. One of a kind is the toddlers posyandu which only serves patients under five years old. At the posyandu a monthly activity will be held in the form of checking the condition of infants. In the checking process there are stages of measurement, recording and reporting. There are many cases of losing books or losing KIA books so the data cannot be updated. With this problem the KMS recording and reporting system was built. It is expected that with this system the possibility of losing KIA books will decrease and the possibility of data errors will also decrease. This system was built using the Android operating system and using the waterfall SDLC (Software Development Life Cycle). This system chose the Android operating system because mobile devices are practical and easy to carry everywhere. If the user loses the smartphone, data about the child's growth is stored on the database server. This system uses MySQL as a database and volley to move data from the database to the system or vice versa using the PHP language. In the needs analysis process, there are 9 functional needs and involve 2 actors namely guest and member. In the implementation process using the Java language as the basic language of the Android operating system. Whereas the testing process uses 2 types of testing namely white box and black box. White box testing uses 2 methods, namely unit testing and integration testing. Black box testing uses a validation testing method to test every need.
