According to the findings of the observations made at this shop, there are a number of barriers to the sales business process, including the level of marketing used, which is still less effective, where product marketing in this shop is only focused on location and depends on customer arrival, and sales recording, which is still done manually using books.</p> <p>Based on these issues, research was conducted with the goal of developing an electronic sales system using the RAD technique and the Unifed Modeling Language (UML) as the system design. A software development methodology that focuses process development cycles quickly is called Rapid Application Development (RAD). The waterfall paradigm served as the foundation for the RAD model. The researchers discovered after testing that the sales application was powered by a computer system.</p> Muhammad Khaerudin, Andy Achmad Hendharsetiawan Copyright (c) 2023 International Journal Science and Technology http://journal.admi.or.id/index.php/IJST/article/view/993 Thu, 16 Nov 2023 00:00:00 +0700 CREATIVE WEBSITE DESIGN IMPLEMENTATION FOR FOOTBALL CLUB SUPPORTERS IN INDONESIA http://journal.admi.or.id/index.php/IJST/article/view/996 <p><em>The return of PSSI to implementing the league after the ban was lifted by FIFA, causing the public's enthusiasm for football to increase. Lots of creativity from the supporters who were present directly in the stadium which was amazing and really attractive and creative. Therefore, it is necessary to form an information media for a forum about the world of supporters in Indonesia and the results of the creativity of the supporters which are made with a web-based computer system. A website that contains information on how to dress supporters, the latest news on supporters and creativity from League I, League II and League III clubs. Making it easier for the public to get to know the various kinds of supporters in Indonesia and also see the creativity of supporters from various regions in expressing their support in the form of creative choreography. In making this website, information is obtained from reference books and internet media.Based on testing the website that has been made, it can be concluded that this Supporter Channel site has good quality for people who want to know about supporter information in Indonesia along with the diversity of creativity that exists with the website address </em></p> Syalis Ibnih Melati Istini Copyright (c) 2023 International Journal Science and Technology http://journal.admi.or.id/index.php/IJST/article/view/996 Wed, 22 Nov 2023 00:00:00 +0700 IMPLEMENTATION OF SIMPLEX METHOD FOR OPTIMIZATION PROFIT ON CHOCOLATE FLAVOR BREAD PRODUCTION http://journal.admi.or.id/index.php/IJST/article/view/1000 <p>Companies that carry out production activities necessarily want the company's goals to be achieved, one of which is optimal profit. Maximum profit in production can be realized by planning the optimal amount of production. The purpose of this study consists of four, namely making a profit formulation to maximize the amount of production, determining the optimal number of brown bread variants that will be produced at Win Bakery, determining the maximum profit in producing bread at Win Bakery, and predicting profits for return on investment. This research was conducted using a linear programming model. Decision variables determine the decisions that will make to achieve the optimal solution. The objective function is a function that describes the goals or objectives in linear programming problems. Relating to the optimal use of resources to obtain maximum profit or to use minimum costs. A constraint function is a form of formulation of the obstacles faced in achieving the goal. The results obtained from the research are the decision variables, with X1 being the number of square chocolate bread productions and X2 is the number of round chocolate bread productions. The objective function of the profit per unit is to maximize Z = 1000X1 + 800X2. The constraint function is the raw material used in making chocolate bread. Furthermore, the optimization of production with POM-QM resulted in the number of square chocolate bread production of as many as 13 piecess and round chocolate bread as many as 25 piecess so that the profit gained in one day was Rp. 32,500. The next calculation, the break-even point by entering fixed costs, variable costs, and profits obtained results in units of 55 units and the total profit earned is Rp. 1,777,00.</p> Stephanus Benedictus Bera Liwun, Tri Mulyanto, Aminah Yumna Aqilah Copyright (c) 2023 International Journal Science and Technology http://journal.admi.or.id/index.php/IJST/article/view/1000 Thu, 23 Nov 2023 00:00:00 +0700 DESIGN AND BUILD WEB-BASED FREELANCE APPLICATIONS http://journal.admi.or.id/index.php/IJST/article/view/986 <p><em>In today's modern era, many people have switched to looking for freelance work. One of the interesting things is freelance work because there is no work attachment to employee status, so that the person can have several jobs at one time. But until now, to find freelance work is not easy because usually many job search applications provide services only for permanent workers. For companies that are looking for freelance labor is also not easy, because freelance job search provider services are also not much. The purpose of designing this Lancer application is to make it easier for people who want to find freelance jobs. This website is designed using UML (Unified MarkUp Language). The method used in building this website uses SDLC (Software Development Life Cycle) which includes the stages of analysis, design, creation, and testing. This website is created using Laravel and MySQL frameworks</em><em>. &nbsp;</em></p> Daffa Sulthon Kautsar, Fivi Syukriah, Desy Kristyawati, Jamilah Copyright (c) 2023 International Journal Science and Technology http://journal.admi.or.id/index.php/IJST/article/view/986 Thu, 23 Nov 2023 00:00:00 +0700 SENTIMENT ANALYSIS USING LONG TERM MEMORY (LSTM) BOOK CASE STUDY: UNSOLICITED ADVICE FOR MURDERERS BY VERA WONG'S http://journal.admi.or.id/index.php/IJST/article/view/995 <p><strong><em>Reading books is one of the most effective ways to reduce stress. In today's digital era, access to finding and buying books is getting easier, so reader reviews are important in choosing books that match interests. However, with a large number of reviews, Natural Language Processing (NLP) with the Long Short-Term Memory (LSTM) method is used to help analyze positive and negative sentiments from many book reviews. This sentiment analysis is useful for readers to evaluate the quality of books, as well as for authors and sellers to find out the opinions of readers and improve the quality of their work. In this study, the book review dataset "Vera Wong's Unsolicited Advice for Murderers" from the Goodreads website is used, which is then divided into training data and validation data with a ratio of 75%: 25%. The Long Short-Term Memory (LSTM) method is used to analyze the sentiment of the reviews. The model architecture built consists of Embedding Layer, LSTM Layer with 128 neuron units, 3 Dense Layer with ReLU activation function, 3 Dropout Layer, and Fully Connected Layer with and Sigmoid activation function, Binary Cross Entropy loss function, and RMSprop optimizer. The model training process was conducted with 30 epochs. The evaluation results show that the model achieved an accuracy of 90%, indicating the model performs relatively well in correctly classifying positive sentiments.</em></strong></p> Tri Sulistyorini, Erma Sova, Nelly Sofi, Revida Iriana Napitupulu Copyright (c) 2023 International Journal Science and Technology http://journal.admi.or.id/index.php/IJST/article/view/995 Thu, 23 Nov 2023 00:00:00 +0700 IMPLEMENTATION OF SIMPLE ADDITIVE WEIGHTING (SAW) METHOD FOR DESIGN AND BUILD DECISION SUPPORT SYSTEM OF LAPTOP SELECTION (Case Study: IT Store) http://journal.admi.or.id/index.php/IJST/article/view/999 <p>Laptop is a small computer that is easy to carry anywhere, which makes everyone want to have one because of its convenience. However, the laptops currently available have various specifications, so users feel confused about choosing and buying the laptop they want. Therefore, this research was conducted to build a web-based decision-support system. The method used in this decision support system is simple additive weighting as a criterion for calculating laptop recommendations. The SAW method is a weighted addition method to determine the weighted sum to determine ranking. User satisfaction test results using a questionnaire using the End User Computing Satisfaction (EUCS) method The results of the calculation of the user satisfaction test obtained a result of 85.66%, which means that the system built can be useful for users in providing laptop recommendations.</p> Gregorius Hariyanto Setiadi, Fenina Adline Twince Tobing, Rena Nainggolan Copyright (c) 2023 International Journal Science and Technology http://journal.admi.or.id/index.php/IJST/article/view/999 Thu, 23 Nov 2023 00:00:00 +0700
