This study aims to regulate bandwidth usage and monitor website access using MikroTik. Bandwidth regulation with the aim of equalizing internet use where the number of students and teachers is 500 people, while monitoring websites and blocking negative websites aims to limit student access, which amounts to 416 students, consisting of 120 junior high school students, 150 vocational high school students, and 150 students. SD 100 and students 66 people. This research was conducted at Asshodiqiyah Vocational School as a technology base in the school environment under the Asshodiqiyah Foundation. The Assodiqiyah Foundation oversees elementary, junior high, and vocational schools and accommodates foreign students as boarding students. The service location is located at Jl. Sawah Besar Timur No 99 Rt.9 Rw. 2 Kaligawe Village, Gayamsari District, Semarang City. The method used in this research is Research and Development (R&D) [4]. This research discusses how to create and implement to the public how to use the Mikrotik tool as a regulator of bandwidth usage and see the sites that are accessed and if necessary block sites that are considered less suitable for students to access. The expected result is an even use of internet bandwidth and security of site access from negative things. So that students will avoid the negative influences that exist from the internet.

The mouth is the entrance to the digestive system and contains accessory organs that are in the early stages of digestion, while teeth are made of a very hard material, namely dentin. (Indah Irma & Ayu Intan, 2013. Many people complain of pain in the teeth and mouth due to lack of hygiene in maintaining the health of this organ. So when people are attacked by dental and oral diseases, people try to do their own treatment, for example buying toothache medicine in the shop. According to Turban (in Vincent, 2011) an expert system is a system that uses human knowledge where this knowledge is entered into a computer and then used to solve problems that usually require human expertise or expertise. The method used is the forward chaining method, namely forward chaining starting from a set of facts (there are) by looking for rules that match the assumptions/hypotheses that exist towards conclusions (Siswanto 2010).
 
 

This study aims to build a library system application that can be used in the library of the Faculty of Engineering UNTAG Semarang based on an RFID card. From the background of the problem, namely, the process of borrowing and returning books is quite long, because to search for borrowed books the librarian must go to the bookshelf and look for the title of the book to be borrowed. The difficulty in making reports, because it is done after the library activities are finished, does not automatically coincide with the process of borrowing and returning services. Starting from the problems above, and paying attention to the number of daily visitors in the library that must be served, the authors propose to create a library service application using an RFID tag that can help the process of searching for member data and library books quickly.

This research was conducted because of the importance of the metaverse in its contribution to increasing GDP. Metaverse business growth in the last 10 years compared to GDP has contributed 2.8% globally. This is what is interesting to study regarding the opportunities and challenges faced in the application of the metaverse. This research was conducted by using a literature review review to obtain a theoretical basis that could support solving a problem that is being or will be studied. Opportunities and challenges of the metaverse in the literature review can be concluded that previous researchers have used a good research methodology using a good theoretical basis and research steps. Most studies show that the metaverse is still in demand as a topic of interest by well-known research and is still a trending theme in the research world. The application of the metaverse platform covers multi-disciplinary fields, including education, health, business/marketing, games, information systems, concerts, fashion events, advertising, virtual real estate ownership etc. This research suggestion needs a detailed discussion of the problems and challenges faced in the Metaverse application in the coming period, in the next 10 years it is predicted that the metaverse will still be a hot topic of conversation globally, the need for metaverse development in various fields, and the need for copyright, brand rights and trade rights in relation to the metaverse-based application platform.

Credit Card (CC) scam In financial markets is a growing nuisance. CC scams increasing rapidly and causing large amounts of financial losses for organizations, governments, and public institutions, especially now that all payment methods for e-commerce shopping can be done much more easily through digital payment methods. For this reason, the purpose of this study is to detect scam CC transactions from a given dataset by performing a predictive investigation on the CC transaction dataset using machine learning techniques. The method used is a predictive model approach, namely logistic regression models (LR-M), random forests (RF), and XGBoost combined along particular resampling techniques that have been practiced to anticipate scams and the authenticity of CC transactions. Model performance was calculated grounded Re-call Curve (RC), precision, f1-score, PR, and ROC.
The experimental results show that the random forest in combination with the hybrid resampling approach of SMOTE and removal of Tomek Links works better than other models. The random forest model and XGBoost accomplished are preferred over the LR-M as long as their global  f1 score is without re-sampling. This demonstrates the strength of one technique that can provide greater achievement alike in the existence of class inequality dilemmas. Each approach, at the same time when used with Ran-Under, will give a great memory score but fails cursedly in the language of accuracy. Compared to the coordinate model sine re-sampling, the accuracy and RS are not repaired in cases where Tomek linker displacement was used. RF and xgboost perform quite well in terms of f1-S when Ran-Over is used. SMOTE increases the random forest draw score and xgboost but the precision score (PS) decreases slightly.
Completely, during a hybrid solution of Tomek delinker and SMOTE was practiced with random forest, it gave equitable attention and RS in the PR-AUC. XGboost failed to increase the PS even though the same re-sampling technique was used. For future research, a fee-delicate study method can be applied as long as fee misclassifications. So for future research, it is very necessary to consider this behavior change and it is also very important to develop predictive models. In addition to this, much larger data is needed so that detailed studies on handling non-stationary properties in CC scam detection can be carried out better.

Gamerground is a computer shop engaged in the sale of laptops, computers, spare parts, accessories supporting and providing repair services. The marketing process is less than optimal because it only sells by phone or social media. There are some problems that occur between them : 1. Stock management is not optimal because of frequent discrepancies between stock records with the amount of goods available so often consumers feel disappointed with the services provided, 2. The issue of uploaded ad duration in uploaded social media will alternate from one product content display to another in a relatively short period of time, 3. The absence of management of consumer sales transactions thus requiring recording of repeated transactions, 4. The decline in sales turnover in recent months, 5. The management of customer or consumer data is less noticed. Based on these problems, this study aims to design a web-based online sales information system mobile on gamerground. This research uses the development of SDLC waterfall model system which consists of planning, analysis, design, implementation and maintenance. Using PHP and MySQL Server programming language as database. The results of research in the form of Online Sales Information System Web-Based Mobile that can facilitate consumers to view products, make reservations for consumers and management for the admin. This information system is equipped with product management features, order data management, customer data management, preparing order reports and payment confirmation. So that this information system can provide convenience both consumer and admin on gamerground.
