Abstract

SDS Nurul Huda is a private elementary school located at Jl. Sei Serayu No 38, Babura, District of Medan Sunggal, City of Medan, North Sumatra Province. This school has been operating since 1978. Currently, student data entry and grading at SDS Nurul Huda are still done manually. Some teachers face difficulties in inputting data and grading due to it being time-consuming, especially for older teachers who struggle with reading numbers. Errors in writing student data and grades also frequently occur. This research aims to develop a data entry and grading application for students as a solution to enhance efficiency in school administration processes and replace the manual system, which is often prone to errors and time-consuming in data entry and grading. The outcome of this research is an Application for Data Entry and Grading for SDS Nurul Huda to facilitate teachers in swiftly and easily inputting student data and grades.

Abstract

Predicting sales of herbal products is the main challenge faced in this research. Currently, forecasting is done solely based on previous sales records, which often prove to be inaccurate. As a result, the company frequently experiences unstable sales and faces difficulties in optimizing inventory and planning product orders efficiently to meet high customer demand. This situation often leads to significant cost losses, forcing the company to reduce capital costs for certain products to cover these losses. The problem arises because the company has not yet implemented an appropriate forecasting method, resulting in estimates that are not supported by a reliable system. This research aims to design and implement a Sales Management Information System for Herbal Products, focusing on the use of the Double Exponential Smoothing (DES) and Double Moving Average (DMA) methods. Additionally, this study aims to compare the two methods in predicting sales by analyzing and calculating the Mean Absolute Percentage Error (MAPE) value for each method. The research uses 200 sales data points from 8 best-selling products, including one of the best-selling products, HNI HEALTH, with data collected from April 2022 to April 2024. The MAPE results from the sales data were then calculated by summing all the MAPE values and dividing them according to the number of MAPEs with an alpha of 0.3. It was found that the DES method is more accurate, with an average Mean Absolute Percentage Error (MAPE) value of 0.285, compared to the DMA method, which has an average MAPE value of 0.292. The DES method is considered more accurate because its MAPE value is smaller than that of the DMA method.

Abstract

One of the methods of securing information systems that is commonly known by many people is passwords. Without realizing it, passwords have an important role in securing information that is confidential. In some applications related to software, such as cellphones, ATM cards, and others. There is also a security system that functions similarly to a password. commonly known as a PIN Code. Although it only consists of numbers, its use is the same as a password, which is to secure information. The stored information is usually digital or database-based. Password security aims to secure a password stored in the database, the password needs to be secured because if the password is known by unauthorized parties or who are not entitled then important and other data will be stolen. The password that is secured is a password that is used daily, be it email passwords, social media, databases, operating systems on the device and others into the database. vigenere cipher algorithm to encode the password in a database. The result of this test is that password security is carried out based on the vigenere cipher method using a visual studio application and utilizing a Database with a MySQL application. The end result used is the result of the security process with the result key having no resemblance to the original record. Formation of keys based on user decisions. It is worth paying attention that the key should not be forgotten.
