Abstract

Anomalies may degrade network performance for specific network traffic. Because of its nature, it causes abnormal network traffic. Using the K-means clustering method, this study addresses the formulation of the problem of detecting network bandwidth usage anomalies. The objective of this study is to identify potential network traffic anomalies. This study uses the K-Means Method to predict the value of the network traffic anomalies that will appear. K-Means operates by repeatedly iterating based on the initial cluster entered, until the same cluster results are discovered. The results of the study indicate that predicting the occurrence of anomalies with K-Means will help suppress activities that impede network traffic.

Abstract

A program of community service has been implemented, with a focus on designing and producing low-cost, easily-assembled solar panels for the Opak-Grembyangan Madurejo Pramabanan village community. Creation of solar panel lighting systems that are practical to use and are capable of producing up to 100 Watts of electricity. The actions taken serve to introduce people to renewable energy sources, educate them about it, and help with solar panel lighting for the master plan area for village tourism development. Village communities may be equipped with the knowledge and skills necessary to create solar panel lights independently and for mass production after receiving continual mentoring and training. Alternative energy management is a more broad goal to be able to lessen reliance on fossil fuels and create a green tourism sector.

Abstract

Penelitian ini bertujuan untuk menggali wawasan yang mendalam dari ulasan Google Maps wisatawan tentang Candi Borobudur menggunakan metode Pemodelan Topik Latent Dirichlet Allocation(LDA). Candi Borobudur, salah satu situs warisan dunia yang terkenal di Indonesia, menerima banyak ulasan dari wisatawan yang berbeda-beda. Namun, untuk mengidenfikasi tren, preferensi, dan aspek yang paling penting bagi pengunjung, diperlukan analisis yang lebih dalam. Dengan menggunakan pendekatan LDA, mengelompokkan ulasan-ulasan ini kedalam topik-topik latensial yang memungkinkan untuk mengeksplorasi pola-pola umum dan perbedaan-perbedaan dalam persepsi dan pengalaman pengunjung terhadap Candi borobudur. Proses pemodelan topik ini mencakup beberapa langkah, dimulai dari persiapan data, pra-pemrosesan data, wordcloud, topic coherence serta pemodelan topik. Adapun nilai koherensi paling baik diperoleh dalam model Latent dirichlet allocation (LDA) adalah topik terbaik dengan jumlah 4 topik. Sedangkan dari hasil analisis pemodelan topik pada metode Latent dirichlet allocation (LDA) pada Kata "candi" (0.050883695), "borobudur" (0.02406518), "tiket" (0.018967053), dan "masuk" (0.018507887), menyoroti fokus pada aspek kuil, aksesibilitas, dan biaya masuk. Kata "jalan" (0.012353696) dan "parkir" (0.011362941) menunjukkan perhatian terhadap infrastruktur, sementara "area" (0.01039175) mengacu pada lingkungan sekitar candi. Istilah "rb" (0.009597249) dan "harga" (0.0092093265) merujuk pada biaya dalam rupiah, dan "beli" (0.008586656) terkait dengan pembelian tiket. Hasil ini memberikan wawasan tentang fokus utama dalam pembahasan Borobudur, mencakup kuil, aksesibilitas, infrastruktur, dan biaya.Kata kunci: Google Maps, Pemodelan Topik, Latent Dirichlet Alloation(LDA), Nilai Koherensi This research aims to extract deep insights from tourists' Google Maps reviews of Borobudur Temple using the Latent Dirichlet Allocation (LDA) Topic Modeling method. Borobudur Temple, one of the famous world heritage sites in Indonesia, receives many reviews from different tourists. However, to identify trends, preferences, and aspects that are most important to visitors, a deeper analysis is required. Using the LDA approach, categorizing these reviews into latent topics makes it possible to explore common patterns and differences in visitors' perceptions and experiences of Borobudur Temple. This topic modeling process includes several steps, starting from data preparation, data pre-processing, wordcloud, topic coherence and topic modeling. The best coherence value obtained in the Latent dirichlet allocation (LDA) model is the best topic with a total of 4 topics.. While based on the results of the analysis of topic modeling with the Latent dirichlet allocation (LDA) method on Borobudur reviews get 4 topic models The best coherence value obtained in the Latent dirichlet allocation (LDA) model is the best topic with a total of 4 topics. While from the results of the topic modeling analysis on the Latent dirichlet allocation (LDA) method on the words “temple” (0.050883695), “borobudur” (0.02406518), “ticket” (0.018967053), and “entrance” (0.018507887), highlighting the focus on aspects of the temple, accessibility, and entrance fees. The words “road” (0.012353696) and “parking” (0.011362941) indicate attention to infrastructure, while “area” (0.01039175) refers to the temple's surroundings. The terms “rb” (0.009597249) and “harga” (0.0092093265) refer to costs in rupiah, and “beli” (0.008586656) is related to ticket purchases. These results provide insight into the main focus of the Borobudur discussion, covering temples, accessibility, infrastructure, and costs.Keywords: Google maps, topic modelling, Latent Dirichlet Alloation(LDA), Coherence Score
