The problem occurs mother who for prenatal check-ups are only given the fetus underweight. Determining the start of pregnancy and gestational age is important to be able to know within the progress of pregnancy. One of the ways to determine gestational age by knowing the first day of the last menstrual period (LMP). With the naegele method, tjis calculation can also be used to calculate the estimated day of birth. As an easy way to estimate the weight of the fetus is to measure the height of the uterine fundus (TFU). Therefore, based on the problems above, an android-based pregnancy calendar and calculation application of gestational age were made by using the Naegele algorithm. The pregnancy calendar and calculation application of gestational age are designed to make it easier for pregnant women to find out the estimated day or birth. The gestational age and normal fetal weight according to gestational age on an android smartphone. Keywords: Naegele, HPHT, estimated birth, gestational age, fetal weight.

Abstract

Online learning media (Online learning) uses a technological approach that is more suited to today's student learning systems compared to conservative methods of learning in the classroom. By looking at the varying number of questions, the weighting of the exercises varies with the number of questions contained in the exercises. As for the examples of questions that consist of 20 questions, each question is worth 5, so if the student answers 20 questions correctly then the student gets a score of 100. The problems encountered in research on citizenship education learning are still manual so that students' understanding of the concepts and rules of citizenship education is still limited. less because it is rote. The problem formulation based on the background above is that the weighting of the questions and answers is not yet known. The benefit of this research is as an information medium to introduce quiz exercises in applications with citizenship education subject matter for students at Vocational High School 08, North Bengkulu Regency with the concept of learning while playing.

Abstract

The increasing development of computer technology has an impact on various fields. Including land and building taxes. Determination of property tax which was done manually has gradually developed using computers. Along with this, mapping technology is also developing rapidly. Therefore, integration between taxpayer data and mapping data is very important for each individual. A Decision Support System is a computer-based information system that takes an approach to generating various decision alternatives to help certain parties in dealing with problems using data and models. The proposed method is Analytic Hierarchy Process (AHP) which is a method that is able to create a sequence of alternative decisions and select the best alternative in a decision support system to increase effectiveness in paying building taxes. AHP allows judgment and decision making based on uncertain and insignificant data. By using the AHP method, hopefully it can help make decisions easier in increasing the effectiveness of land and building tax payments at the Seluma Regency Revenue Agency Service. The decision support system application to increase effectiveness in paying land and building taxes in the regional revenue agency of Seluma district was successfully built using the Analytic Hierarchy Process (AHP) method. Incremental research methods can be applied for application development. Application testing was carried out using the Blackcox method and the results the application is declared suitable for implementation.Keywords: SPK, Property TAX, AHP

Abstract

Information technology-based sales applications have emerged as essential solutions for optimizing sales processes, tracking inventory, and understanding customer purchasing patterns. Fokus Computer Store offers a range of products, including computer components, laptops, as well as accessories such as mice, mouse pads, keyboards, USB drives, and other computer components. However, challenges arise in sales efficiency, where certain items tend to accumulate without being sold over extended periods, impacting the store's cash flow. Therefore, an application capable of providing product recommendations based on previous sales data becomes crucial in assisting the store in effective inventory management and maintaining a smooth cash flow. The Apriori method is one form of association rule in the field of data mining. Alongside Apriori, there are other methods within this category, such as Generalized Rule Induction and Hash-Based Algorithms. The Apriori method, being a proven effective algorithm for association analysis, will be employed to uncover potential hidden purchasing patterns within the store's transactional data. By analyzing customer purchase data, this application can identify relationships between frequently co-purchased products. The results of this analysis can be utilized to formulate product recommendations for customers, enhance cross-product sales opportunities, and support inventory management decisions. This application can serve as a point-of-sale system at Fokus Computer Store, with the ability to display the outcomes of the Apriori algorithm calculations based on the input sales data. Despite the application developed by the author having certain limitations, particularly in terms of user interface and data, the author anticipates receiving constructive criticism and suggestions to aid in refining the application for the betterment of its future iterations

Abstract

Indonesia is the most populous country in Southeast Asia and a great asset for the development of the Indonesian nation. A large population, if not managed properly, can pose problems in the future. The significant number of unemployed individuals in Indonesia creates its own challenges. The workforce in Indonesia still consists of a significant portion with primary and secondary education, while those with tertiary education are relatively few. The workforce can become the spearhead by creating job opportunities (job creators), so reducing unemployment cannot solely rely on job creation through private or foreign investment and the government. The tough competition among the increasing number of unemployed individuals each year has led to a new option, namely starting a self-employed business, which falls under the category of micro, small, and medium enterprises (MSMEs). MSMEs play a crucial role in improving and growing the community's economy. MSMEs are considered capable of withstanding any situation to achieve the welfare of the society. Establishing a new MSME is a challenging decision for those with limited funds, and careful consideration is required before starting one. The abundance of business options that can serve as references does not always guarantee success since not all businesses will thrive. Before deciding on the type of self-employment to pursue, prospective entrepreneurs must conduct research first. Therefore, there is a need for education and guidance for prospective entrepreneurs to avoid missteps when starting an MSME. The current technological advancements can be utilized to assist prospective entrepreneurs in providing relevant data related to self-employment, one of which is through the use of smartphone technology. Users can access literature regarding the process of establishing a self-employed business and learn from the experiences shared by entrepreneurs who are currently building their businesses

Abstract

In today's digital era, digital images play an important role in various fields, including image processing, surveillance systems, and medical image processing. However, one of the main challenges is that low-resolution images often experience quality degradation, so the loss of important details caused by noise and blurring makes the information in the image unclear. To overcome this problem, various image processing methods have been developed, including the Otsu Thresholding and Canny Edge Detection methods. This study will compare two methods for improving the quality of low-resolution images, namely Otsu Thresholding and Canny Edge Detection. This experiment was conducted to determine how effective the two methods are by testing several low-resolution image samples and then evaluating the results based on the PSNR, MSE, and SSIM metric values. The experimental results obtained show that the Otsu Thresholding method outperforms Canny Edge Detection in terms of improving image quality, as evidenced by better PSNR, lower MSE, and SSIM closer to 1. Thus, Otsu Thresholding is recommended as a more effective and optimal method in low-resolution image processing. Therefore, it is hoped that the results of this study can be a reference for developing more effective and optimal low-resolution image processing methods in the future.
