Abstract

Industri barbershop menghadapi tantangan dalam meningkatkan kualitas layanan dan efisiensi operasional seiring meningkatnya kebutuhan pelanggan terhadap layanan yang cepat, personal, dan berbasis digital. Sebagian besar sistem reservasi dan transaksi yang digunakan saat ini masih berfokus pada pencatatan operasional tanpa memanfaatkan data pelanggan sebagai sumber informasi strategis untuk mendukung pengambilan keputusan. Penelitian ini bertujuan untuk mengembangkan Framework Data-Driven Customer Analytics yang terintegrasi dengan sistem informasi reservasi dan transaksi guna meningkatkan kinerja operasional dan kualitas layanan pada usaha barbershop. Framework yang diusulkan memanfaatkan data reservasi, transaksi, frekuensi kunjungan, preferensi layanan, dan pola perilaku pelanggan untuk menghasilkan informasi analitik yang mendukung pengambilan keputusan berbasis data. Pengembangan sistem dilakukan menggunakan metode Waterfall yang meliputi analisis kebutuhan, perancangan framework, implementasi sistem, dan pengujian. Evaluasi sistem dilakukan melalui pengujian fungsional menggunakan Black Box Testing serta analisis kinerja berdasarkan indikator operasional dan layanan pelanggan. Hasil penelitian menunjukkan bahwa framework yang dikembangkan mampu mengintegrasikan data pelanggan secara efektif, menyediakan informasi analitik yang relevan bagi pengelola, meningkatkan efisiensi proses reservasi dan transaksi, serta mendukung penyusunan strategi layanan yang lebih tepat sasaran. Kontribusi penelitian ini terletak pada pengembangan model customer analytics berbasis data yang dapat dimanfaatkan sebagai dasar pengambilan keputusan untuk meningkatkan daya saing dan keberlanjutan bisnis barbershop di era transformasi digital. Kata Kunci: Customer Analytics, Data-Driven Framework, Sistem Informasi Reservasi, Sistem Transaksi, Barbershop, dan Pengambilan Keputusan Berbasis Data.

Abstract

After the internet was discovered, humans were greatly helped by internet access, both in the economic sector and in the dissemination of news or information. However, the more the internet develops, the more uses the internet has, and the internet is often misused by internet users, such as online gambling, pornography and violent content. So if there are no restrictions on accessing content or websites that contain elements that are not good and can be accessed very easily by internet users, it is feared that if minors want to open these websites, it is feared that it could damage morals. children who are still immature in using the internet, therefore a Proxy Server is needed which aims to filter internet access from prohibited sites which are likely to be accessed by users who are immature in using the internet and provide healthy internet implementation by adding a proxy server as filtering websites. filtering or blocking websites that are inappropriate for internet users. The results of this research are that the network security tool using a proxy works if there is an attempt to open a website listed on the list of websites that are not allowed to be accessed and the proxy server network security system, there is no limit to how many websites can be blocked.

Abstract

This research aims to compare the accuracy of the Naïve Bayes and Decision Tree methods in predicting Land and Building Tax (PBB-P2) compliance in Tebing Tinggi city. The data used includes tax and payment determination for 2022 and 2023. The methods applied include data preprocessing, use of an inconvenience matrix for evaluation, as well as measuring accuracy with various data sharing ratios (80:20, 75:25, 70:30, 60:40, and 50:50). The research results show that the Decision Tree model consistently has much higher accuracy compared to the Naïve Bayes model, with accuracy reaching 99% at all data split ratios, while Naïve Bayes shows accuracy between 54% and 56%. The confusion matrix supports this finding by showing that the Decision Tree model has higher True Positives and True Negatives, and lower False Positives and False Negatives compared to Naïve Bayes. In conclusion, the Decision Tree method is more effective in classifying tax compliance compared to Naïve Bayes so that it is a more optimal choice for a tax compliance classification system based on the accuracy and performance obtained from this research.

Abstract

The rapid development of technology has significantly had an indirect impact on all aspects and dimensions of human life. Online shopping is a form of technological progress. Online shopping is all activities related to online transactions that take place via the internet or other electronic networks. The online shopping process no longer requires face-to-face contact but can be done simply by communicating via the internet. Based on the researcher's preliminary study, at SMK Negeri 1 Tanjung Pura many students spend time shopping online. This online shopping is not only done during break times or after school but is also done during class hours. Based on researchers' observations, students at SMK Negeri 1 Tanjung Pura who like online shopping have an impact on their education. Their study time is reduced, causing their grades to drop. Apart from that, online shopping affects its users, it can cause relational and social problems which have made children rarely socialize with their surroundings, withdraw from social interactions and ultimately make their lives uncontrollable because online shopping takes over their minds. Therefore, through this task, an analysis of the level of online shopping addiction was made using the K-Nearest Neighbor method. The data used is data from students at SMA Negeri 1 Tanjung Pura and the results of this data will be classified using the K-Nearest Neighbor algorithm to find out whether someone is addicted to online shopping based on the level of addiction. The results of the analysis of the level of online shopping addiction in these students, whether they have low addiction or high addiction.

Abstract

The advancement of information technology has had a significant impact on various fields, including education. One area that has been greatly influenced is the teaching of programming algorithms, where technology helps simplify the understanding of fundamental concepts, such as data sorting algorithms. This study focuses on the implementation of the Insertion Sort algorithm using the Flowgorithm application to facilitate the understanding of the data sorting process. Flowgorithm is a software tool that enables the creation of flowcharts to visually represent the steps of an algorithm, which can then be translated into programming languages. The Insertion Sort algorithm was chosen due to its simplicity and its effectiveness in sorting small datasets. This study covers the design and implementation of the algorithm using Flowgorithm, testing with positive integer data, and verifying the correctness of the sorting results through manual calculations. The test results show that the algorithm works correctly, producing the proper sequence from unsorted data. Additionally, the pseudocode generated from the Flowgorithm design can be translated into a programming language like Python. This research contributes to enhancing the understanding of algorithmic concepts, particularly sorting algorithms, by using Flowgorithm as an effective learning tool.
