Abstract

Management plays a very important role in supporting the running of the asset inventory and its management. Currently, the drug supply asset management system at the Kaka Bekasi Pharmacy is still carried out using a simple computerized method, namely using the Microsoft Excel application and manual recording, causing various kinds of problems. The problem faced by the pharmacy is that the asset management of drug supplies in the process of recording orders, purchases, sales is not recorded accurately and is well integrated so that in the search process one has to look for drug stock data, as well as being slow in knowing which drugs will expire. Lack of security in the system is also a problem with pharmacies as it can be accessed by anyone. Therefore, to assist managers in drug asset management, a Web-based Drug Inventory Asset Management Information System was designed using the Prototype Method at the Kaka Bekasi Pharmacy, system design using UML, PHP programming language with sublime text editor and MySQL database management software. The result of this research is a prototype that can be further developed in order to produce an asset management information system that can be implemented at the Kaka Bekasi Pharmacy.

Abstract

Visualization is a tool that makes it easy to understand the information presented in charts and graphs. The purpose is to facilitate data exploration. Therefore, the authors use relationship diagrams as Mathematical Modeling to explore data that has a relationship between tables. The purpose of the study is to map the dataset, which found out a possibility that some errors when entering data. In the mapping process, we use the composition of relations, thus making the number of possible relationships in the mapping. Because of the problem, the table mapping use into a binary relationship diagram based on the number of attributes in a table. The conclusion obtained when using a binary relation diagram is that the more column in a table, the more mapping relationship diagrams must be drawn. Although the relationship diagram becomes very complex, it handled if the tables are correctly normalized.

Abstract

Almost all aspects of human life has been touched by the development of information and communication technology. Especially in the current pandemic where face-to-face interactions are very limited, so sometimes information is not conveyed clearly and precisely. For example, in the case of work when there are new employees who have difficulty getting information or just asking colleagues because they cannot convey information clearly. The lack of access and the amount of access needed to obtain certain information makes it difficult for new employees to work even though the questions asked are the same questions asked by one employee or another. Chatbot is the result of technological innovation that aims to facilitate the process of exchanging information by using interactive programs. With this text-based Chatbot application, you can minimize the time needed to answer questions because it is automated. The Naive Bayes Classifier algorithm was used in making Chatbot in this study by previously creating a collection of frequently arising questions (FAQ) containing 10 questions and their answers which will be used as a dataset. By using a split ratio of 0.8 and a total of 60 questions, the resulting accuracy value is 93.33% and the error value is 6.66%.

Abstract

Identifying the corona virus on international arrival passengers aims to find out whether the passenger has the corona virus or not. Corona virus is one of the health problems that really needs our attention now. Because this virus can cause death, and the way the virus is transmitted is very easy and fast. There are many things that can be done to reduce the spread of this virus to the territory of Indonesia, one of which is to identify the body temperature of each passenger on international arrivals at the airport. At the airport the identification of this virus is done by using Artificial Intelligence. One of the things that is the goal of developing artificial intelligence (AI) is to help humans. This often means imitating the abilities and intelligence of the person he is trying to help or replace. The tool used is the Thermal Scanner Camera that can see directly the body temperature of the passenger. And there are several kits that have been made to check directly whether there is a corona virus in the human body by using the Rapid Test and PCR Test. This research was conducted to see how important AI (artificial intelligence) is in helping reduce the spread of corona virus. According to some existing data, the use of Thermal Scanner Camera can help reduce the spread of corona virus at airports.
