Abstract

Royal Prima Hospital faces challenges in managing its drug inventory. Each month, the available quantity of drugs remains the same without considering the actual needs, based only on the amount of drugs sold. As a result, there is often an excess of drug stock, leading to reduced shelf life, lower drug prices, and unsatisfactory patient service. This situation is certainly detrimental to the hospital. To help hospital management reduce errors in forecasting drug sales, the Double Exponential Smoothing forecasting method with an alpha of 0.6 was applied, as the sales data show a trend. This method provides a solution that can be used to predict the number of drugs that will be sold in both the short and long term with a high level of accuracy. The forecasting results produced a Mean Absolute Error (MAE) of 791.64, a Mean Square Error (MSE) of 17,887,289,511.31, and a Mean Absolute Percentage Error (MAPE) of 0.78%. Thus, hospital management can manage drug inventory more efficiently and reduce wastage. This study offers significant benefits by providing a more accurate approach to forecasting drug sales.

Abstract

Waste is a rather serious issue. One of the main factors is the lack of awareness in society regarding proper waste management and disposal, as well as a lack of concern for environmental cleanliness, which results in an increasing accumulation of waste that can lead to environmental pollution and diseases affecting public health. Therefore, this research was conducted to provide an alternative solution for the community, enabling people to easily manage and dispose of waste properly and instill the habit of waste separation. This was achieved through the design and development of a web and mobile-based waste management application called E-Bin for the residents of Ciwaru village. The research was carried out using the waterfall method, which involved data collection and system design based on existing systems. The application was successfully built and resulted in two systems a web system for administrators and a mobile application that is easily accessible to the community. The application was developed using Android Studio with Java as the programming language, MySQL as the database server, and Visual Studio Code as a supporting tool. It has been tested using black-box testing, demonstrating that the application functions well and is suitable for use.

Abstract

Almost every home has a Wi-Fi (Wireless Fidelity) internet connection, and it is normal practice to safeguard internet access to prevent unauthorized use and to make sure that internet usage does not exceed costs. Using WPA (Wi-Fi Protected Access) protection is one method of securing internet access over Wi-Fi. However, some people are still attempting to crack WPA2 in order to obtain unrestricted, free, and unauthorized access to the internet. The purpose of this study is to identify the ways in which AeroWPA can be utilized to mitigate the problem of obtaining WiFi access without a password. AeroWPA and Wi-Fi Deauther are used in the keamanan access control procedure, with the Router Nirkabel Totolink N300RT serving as the subject of the investigation in order to identify any kind of anomaly. The study's findings indicate that the process of changing a password in an AeroWPA script is hindered by password cracking, which causes a connected phone to freeze twice. Additionally, SSID security is compromised by using a password that is obtained from a logged-in user and the script itself employs Social Engineering.

Abstract

Kefamenanu City is located in East Nusa Tenggara (NTT) Province, precisely in North Central Timor Regency, this city borders land directly with the State of Timor Leste. The population density level in Kefamenanu city is relatively lower when compared to other regions in NTT, but by looking at the fact that most of the area is dominated by dry land and the increase in population growth rate that always increases every year, then in terms of providing land for housing locations will be a challenge for the TTU Regency Government. Determining the location of houses requires consideration of various aspects such as water availability, disaster vulnerability, public facilities, distance from trade centers, road conditions, transportation facilities, and land prices. This research aims to develop a Geographic Information System (GIS) that provides information related to disaster-prone areas and is equipped with a Decision Support System (SPK) using the Simple Additive Weighting (SAW) method. SAW method is used to help people in choosing housing locations based on the criteria they have. The results show that this system is effective in providing information and supporting decision making on housing locations that are safer and more comfortable, and can minimize potential disasters. In conclusion, the proposed system can be a valuable tool for local governments and communities in planning housing development in disaster-prone areas.

Abstract

The development of software technology is currently very fast and significant, especially in information systems, and one of them is the development of learning application technologies for mobile devices. In time, application technologies can also be learned through mobile phones. Android is an operating system that supports learning from mobile applications. English For Skill (EFS) is one of the English learning courses in Kediri. Almost a dozen or even hundreds of students do English to learn skills and are fluent in English, but the learning system used in the institution still uses a paper text system and the reason is that there are many books scattered and useless books. So we need a learning and registration app that is accessible to students anytime, anywhere. Based on this, this study aims to create an Android based registration and learning application for English For Skill institutions. This registration and learning application uses the software development lifecycle methodology. The steps in this methodology include analysis, design, implementation, testing and maintenance. The resulting registration and learning application should make it easier for institutions to implement the registration and learning systems that have been implemented.
