Abstract

Today's rapid development in the world of information technology causes almost all human work to become lighter and more effortless. One of them is the teacher's duties in teaching and giving grades. Applications already available on laptops or computers, such as Microsoft Office, can create more interactive teaching materials, create financial reports, or manage grades. However, most teachers who are familiar with laptops or computers can only operate the simple functions available in these applications, so the work that can be done is still limited. This service is carried out through training methods with material on using Microsoft Office applications (Word, Excel, PowerPoint) for teachers. The school being targeted is SD Negeri 7 Kesiman, whose environment is already fluent in technology but whose human resources are still limited in operating computers. The training material in the form of a Microsoft Office training module compiled by the service society team is used as a learning medium for teachers at SD Negeri 7 Kesiman. Evaluation of training activities used methods in the form of pre-test and post-test, in which the results showed that the ability of teachers at SD Negeri 7 Kesiman to understand the material had increased from before. These results also illustrate that the modules are arranged to make it easy to learn and conform to the needs of the features that the teacher often uses. Keywords : Competency, computer, information technology, Microsoft Office, teacher.

Abstract

The majority of the population uses clean water sourced from the PDAM (Indonesian Regional Water Supply Company) pipeline to meet their daily needs. However, clean water utilization is sometimes not smooth because the upstream's water supply is stalled or the PDAM pipeline disrupted. This disruption that often occurs slowly causes routine community activities, such as bathing or cooking, become stop because clean water is a basic need. Thus, a system is needed to provide early warning when the PDAM water supply starts to have problems so that the community can make initial anticipation. This study designed a prototype of an early warning system using an Arduino-based water flow sensor that records water flow discharge data on the PDAM pipeline and sent to the Firebase Realtime Database to be monitored in real-time through an Android application. The system testing is done by black-box testing, i.e. we check all functions of this system, mainly on sending a warning notification when the water flow debt is at a low rate. In the end, by using this system, the user can prepare themselves early, such as collecting residual water debit in the tub and save water when there is a disruption in PDAM water.

Abstract

The development of information technology makes many organizations utilizing it in their business process. For example, hospitals use certain information systems in medicine management. We observe that most medicines applications do not provide the drug usage prediction feature so that this situation causes the hospital staff being difficult in providing enough medicines. Therefore, in this experimental research, we developed an application in the form of a simple design for helping the hospitals in predicting daily medicine usage. This application also provides medicines stock management and doctor diagnosis features. The Brainy library is used to facilitate implementing the backpropagation neural network method in PHP programming language. We choose PHP because this server script is widely used in information system development. We demonstrated that the mock-up as the result of this development is able to work properly. For further study, we suggest expanding this mock-up become a full hospital information system that covers many functions in medical centers.
