Abstract

Nolbas svnr is a business engaged in the clothing industry which refers more to t-shirt screen printing. This business carries out its activities based on customer orders received through orders from individuals, shops, and schools. With the many types of screen printing that are made, the number of orders received and executed by Nolbas Svnr increases. Screen printing production at Nolbas Svnr is always changing every year. The main objective of this research is to obtain a predictive model for the amount of screen printing production using the Linear Regression method based on the number of orders obtained each year. The results that can be obtained in research can help for the supply of raw materials, the amount of raw materials, paint and so on. This study uses the linear regression method to process sales data using attributes such as year, customer name, price of goods, price of materials and the number of orders. of 0.5601. The results of the constant values ??and regression coefficients are used to predict the amount of screen printing production in 2023 at Zerobas SVNR and the predicted value is 3391. Evaluation of the multiple linear regression model shows an MAE value of 3.7247, an MSE value of 17.8633 and an R2 score of 87% .

Abstract

Analisis sentimen adalah proses yang bertujuan untuk memahami opini pelanggan dengan mengklasifikasikan ulasan menjadi sentimen positif, netral, atau negatif. Penelitian ini bertujuan untuk mengembangkan model analisis sentimen berbasis algoritma Support Vector Machine (SVM) terhadap ulasan pelanggan Toko Livia Cirebon di platform Shopee. Pendekatan penelitian dilakukan secara kuantitatif, dengan tahapan meliputi pengumpulan data, pra-pemrosesan teks (cleansing, normalisasi slang, tokenisasi, penghapusan stopword, dan stemming), pelabelan menggunakan Inset Lexicon, transformasi data teks menjadi vektor numerik dengan metode TF-IDF, pelatihan model SVM, serta evaluasi performa menggunakan metrik akurasi, precision, recall, dan F1-score. Model yang dikembangkan mencapai akurasi sebesar 91% dengan performa terbaik pada sentimen positif (F1-score 95%), meskipun performa pada kategori netral dan negatif masih memerlukan peningkatan. Hasil penelitian ini menunjukkan bahwa algoritma SVM efektif untuk analisis sentimen dalam e-commerce, memberikan wawasan strategis bagi pemilik usaha untuk menyusun strategi pemasaran dan meningkatkan kualitas layanan.

Abstract

The development of a web-based chatbot service for Puskesmas presents a potential solution to improve the accessibility and efficiency of healthcare services. This research uses Flowise AI, a chatbot development platform that leverages machine learning technology to support dynamic information processing and provide accurate and relevant responses to users. Flowise AI is integrated with Langchain Retriever to further enhance dynamic information processing, ensuring accurate and relevant responses to users. Using the Rapid Application Development (RAD) methodology, the chatbot development follows a fast-paced cycle, enabling early prototyping and continuous user feedback. The chatbot is tested using Black Box Testing to verify functionality and System Usability Scale (SUS) to evaluate usability. The test results show that the chatbot is able to provide accurate responses to patient queries, especially on relevant health topics, with an SUS score of 75, which falls within the "good" category. This score reflects that the chatbot is easy to use and acceptable to users. This technology allows the chatbot to provide more accurate, relevant, and contextual responses to patient inquiries, while dynamically accessing information from various sources, thereby improving the efficiency and effectiveness of healthcare services.

Abstract

Abstrak : Layanan darurat non kebakaran di Kabupaten Cirebon menghadapi beberapa kendala, seperti alokasi sumber daya yang tidak efisien dan terbatasnya pemanfaatan analisis data. Penelitian ini bertujuan untuk meningkatkan pengelolaan regu penyelamat dengan memanfaatkan algoritma K-Means sebagai metode pengelompokan data. Menggunakan pendekatan data mining dan penerapan Knowledge Discovery in Database (KDD), penelitian ini menganalisis 874 data layanan darurat non kebakaran yang dikumpulkan pada tahun 2023-2024. Data yang dianalisis meliputi Lokasi kejadian, jenis penyelamatan, tingkat keparahan insiden, waktu respons, dan distribusi regu penyelamat. Proses penelitian dimulai dengan konversi data kedalam format numerik. Hasil menunjukan nilai DBI terendah sebesar 0,080 dengan empat klaster optimal, yang meningkatkan efisiensi distribusi regu penyelamat=====================================================Abstract : Non-fire emergency services in Cirebon Regency face several obstacles, such as inefficient resource allocation and limited utilization of data analysis. This study aims to improve the management of rescue squads by utilizing the K-Means algorithm as a data clustering method. Using a data mining approach and the application of Knowledge Discovery in Database (KDD), this study analyzed 874 non-fire emergency service data collected in 2023-2024. The data analyzed included Location of incident, type of rescue, severity of incident, response time, and distribution of rescue squads. The research process started with converting the data into numerical format. The results showed the lowest DBI value of 0.080 with four optimal clusters, which improved the efficiency of rescue squad distribution.

Abstract

Toko Sembako Ibu Iyu merupakan toko ritel tradisional yang menghasilkan data transaksi dalam jumlah besar setiap hari, sehingga diperlukan teknik pengolahan data yang mampu mengekstraksi informasi bernilai guna mendukung pengambilan keputusan. Penelitian ini menerapkan metode data mining menggunakan algoritma association rule mining, khususnya FP-Growth, untuk mengidentifikasi pola keterkaitan produk dan memahami kecenderungan pembelian konsumen. Data yang digunakan mencakup transaksi periode Januari hingga Juni 2024 yang berisi kode transaksi, tanggal, serta daftar produk yang dibeli. Tahapan penelitian meliputi seleksi data, pembersihan duplikasi, standarisasi penamaan, dan transformasi ke format basket transaction sebelum dianalisis menggunakan FP-Growth dengan minimum support 0,01 dan minimum confidence 0,6. Hasil penelitian menghasilkan 11 aturan asosiasi, dengan aturan terbaik menunjukkan bahwa konsumen yang membeli Marlboro Kretek cenderung membeli Cheetos BBQ/Jagung Bakar, dengan nilai support 1,2% dan confidence 95,7%. Temuan ini dapat dimanfaatkan untuk strategi penataan produk, promosi bundling, dan optimalisasi manajemen persediaan sehingga mendukung peningkatan efisiensi operasional toko ritel tradisional.
