Abstract

The University of Victory Sorong realizes that there are limitations in controlling every student's development as a whole; it takes synergy with parents so that both parties can show their presence together. This parent/students’ guardian information system that was built makes it easier for parents to monitor or control the academic and non-academic activities of students of the University of Victory Sorong. Parents can help the Head of the Study Program to discipline students in improving student learning. Parents can also consult with the head of the study program regarding their child's development. In this information system, too, parents can see the student's grade as the final result of their learning efforts for one semester. This research was built using the SDLC method with a waterfall. Data were collected using documentation, observation, and interviews. This web-based parent/students’ guardian information system allows each parent/students’ guardian user to easily access the desired information. Some of the information that can be accessed is the Study Plan Card, Study Result Card, Student’s Transcript, and can consult with the Head of the Study Program through the Chatting feature. Programming language using PHP and MySQL database. The system is built in a user-friendly manner so that the system is equipped with an interface that is easy to understand and attractive.

Abstract

The government through the Ministry of Religious Affairs canceled the departure of pilgrims from Indonesia in 2020. The decision was taken, considering the Covid-19 pandemic still plagues almost all parts of the world, including Indonesia and Saudi Arabia. "Saudi Arabia has never opened access for pilgrims from any country. As a result, the government could no longer have enough time to make its main preparations in the service and protection of Jemaah. Based on this fact, the government decided not to send pilgrims in 2020. Judging from the charts and data recorded from April to December 2020 there was a sharp increase. There were 743,198 confirmed cases of infection, 109,963 cases treated, 22,138 cases died and 611,091 were declared cured. This is a consideration of the government in taking the decision to lower the letter of cancellation of hajj departure in 2020. To retrieve this sentiment data the author took the data methodology from Twitter by using the data retrieval step using orange anaconda tools with the amount of data obtained as many as 670 tweets that have 3 variables that are positive by 37%, negative 12% and neutral 51%. To analyze sentiment data from Twitter the author used 3 classification methods and produced an accuracy value of KnN of 0.507, Random forest of 0.531 and Naïve bayes of 0.532. Based on the results of the analysis conducted by the author that the response or comments of the public to the delay / cancellation of the hajj departure was reaped a neutral response and support the government's move. Of the 3 methods used, the most superior method is the Naïve bayes method because it uses probability and statistics.

Abstract

Backpropagation is an artificial neural network that has the architecture in conducting training and determining the right parameters to produce the correct output of similar but not the same input. One of the parameters that influences the determination of bacpropagation architecture is the rate of learning, where if the value of the learning rate is too high then the network architecture becomes unstable otherwise if the value of the learning rate is too low the network architecture converges and takes a long time in training network architecture. This research data is secondary data sourced from UCI Data Mechine Learning. The best network architecture in this study is 13-10-3, with different learning rates ranging from 0.01, 0.03, 0.06, 0.01, 0.13, 0.16, 0.2, 0.23, 0.026, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.9. From the 21 different learning rate values in the 13-10-3 network architecture, it is found that the level of learning rate is very important to get the right and fast network architecture. This can be seen in experiments with a learning rate of 0.65 can produce a better level of accuracy compared to a learning rate smaller than 0.65.

Abstract

Payroll is a form of compensation given to employees as a form of appreciation for their work. For this reason, an organization or company must be able to manage its employee agreements properly and correctly, because it is related to employee welfare. At this time, there are still many organizations that do not have a good payroll information system. This can cause problems such as errors in making a salary recap caused because the data processing is still done manually. Besides that, making a payroll report takes a long time, because the payroll data documentation is still not neatly arranged. With this problem, the existing payroll information system is less effective. Therefore, it is necessary to develop a better payroll information system, with the aim of helping solve these problems. To achieve this goal, it is necessary to have an appropriate model in system development such as the use of the Rapid Application Development (RAD) model. With this RAD model, it will be clearer the stages that must be carried out in system development, so as to produce a payroll program application that can help solve existing problems
