Abstract

The rapid development in the telecommunications and digital world today makes android-based mobile devices basic needs for many people. The devices have even provided various kinds of learning media for the community. Further, even though the devices are easily to apply as learning media, they have not been a priority for Muslims in improving their knowledge, such as Sirah Shahabiyah (the journey of a female companion of the Prophet Muhammad). Due to the community’s little interests in learning Sirah Shahabiyah, it is necessary to create a learning application that allows the user and the community to easily learn it. The methods used to collect the data of this research are field study, literature review and previous literature review. The system is developed using a prototype system development method consisting of the stages of planning, analysis, design and implementation and is designed using Unified Modeling Language (UML). The result of this research is a learning application in the form of android-based Sirah Shahabiyah, by which the user and the community can easily learn Sirah Sahabiyah, facilitating pleasant and effective learning activities.

Abstract

Indonesia is a democratic country in which elections for President, Governor, Regent, and Village Heads are still conducted conventionally, where there are still many shortcomings, including the problem of sending ballot logistics, old calculations and inaccurate population data with voters. who do not get their voting rights so that it is less effective in its implementation. To overcome this, especially in the selection of the Village Head, in this study a web-based electronic voting system (e-Voting) was made using a fingerprint sensor that aims to collect voters' data so that voters get their voting rights and their voting rights cannot be used by other citizens. The method used in developing this application is the waterfall method which includes the stages of needs analysis, system design, coding and testing, testing and maintenance. The result of this research is an up to date e-Voting system for counting votes, so as to minimize fraud occurring at the time of village head election. So the conclusion obtained from this study that web-based e-Voting using a fingerprint sensor can produce a quick election winner decision because it does not require tiered and accurate vote counting because citizens who choose according to the data registered.

Abstract

The implementation of a quality management system is inseparable from the work culture of the company concerned. The better the work culture of the organization, the more effective the ISO 9001 quality management system is implemented. As with the health and safety management system or commonly called OHSAS 18001 K3 management, and the ISO 14001 environmental management system it cannot be separated from the application of work culture 5R. If the implementation of the 5R culture goes well, the quality management system, K3 system and environmental management system will certainly have a good effect on its implementation. PT. Kayu Permata has a 5R program which is held regularly every Friday of the week. In the process of determining the best department, it can also be done using a decision support system by calculating the Analytical Hierarchy Process (AHP) method so that selection can be done quickly, precisely and accurately. Keywords: 5R Program,K3 System, AHP Method, ISO.

Abstract

Postpartum haemorrhage factor is a contributor to the Maternal Mortality Rate (MMR) 19.7% in the range 12.9 - 28.9 with 480,000 deaths worldwide and 479,000 from developing countries such as Indonesia. In Indonesia the MMR is 305/100,000 Live Births (LB) of the Millennium Development Goals (MDGs) target of only 102/100,000 LB. To achieve the MDGs target, the MMR needs to be lowered, then formulated the problem of how to make an Android-based expert system using the decision tree method so that it can predict Postpartum Haemorrhage from an early age. With the aim of being able to produce an Android-based expert system to predict Postpartum Haemorrhage, so that cases of death caused by Postpartum Haemorrhage receive medical attention from an early age. The expert system makes predictions from logic in an Android-based program using the SDLC structured design system design method and a parallel development model. This logic has gone through the process of classifying a dataset using the Decision Tree method manually and using Rapid Miner. The Decision Tree logic produces three statements of PPH, NO PPH and Potential PPH which are entered using the Java programming language on Android to become an expert system. Pregnant women with predicted PPH and Potential PPH from the expert system can consult a doctor to get the medical personnel they need early to prevent maternal death caused by Postpartum Haemorrhage.
