Abstract

Masyarakat dewasa ini lebih sering melakukan pembelian produk melalui daring. Hal ini tentu membutuh-kan kecermatan dalam membaca ulasan guna mendapatkan produk yang baik. Sentimen analisis dilakukan untuk menganalisa ulasan pengunjung dari komentar sebuah produk dalam media sosial. Penelitian kali ini difokuskan kepada ulasan produk handphone merk asus zenfone2 yang diambil dari amazon.com guna mengetahui sentimen pengunjung website terkait produk yang dipilih. Proses pengolahan data tersebut dimulai dari pemilahan ulasan yang didapat menjadi perkalimat untuk mempermudah proses selanjutnya. Untuk mendapatkan noun dan adjective dari kalimat tersebut, dilakukan tahapan preprocessing seperti lower case, tokenisasi, lemmatization, serta POS tagging. Noun yang didapat dari prepocessisng tersebut digunakan dalam algoritma FP-growth untuk menemukan fitur pada handphone asus zenfone2 yang sering dibicarakan. Sedangkan adjective yang di dapat, akan digunakan untuk mendeteksi apakah kalimat yang mengandung fitur tersebut bernilai positif atau negatif. Hasil dari analisis ini dapat digunakan customer dalam mempertimbangkan produk tersebut tanpa harus membaca ulasan satu persatu.

Abstract

Preliminary. The Banten Jaya University Library repository system still uses the conventional method of storing it on a shelf in the reference room, this makes it difficult for students who are completing their final project/thesis to access it online. Moreover, with the closure of the campus due to the COVID-19 pandemic, the PSBB and PPKM were continued. Research purposes. This research makes it easier for students to access library repository collections wherever they are, measure the extent of students' literacy skills in utilizing information sources, and show the impact on their research performance. Research methods. The data collection method uses a questionnaire, with statistical analysis, a model for assessing student literacy skills with Empowering 8, which is a research method used to produce products and test the effectiveness of these products, with the Waterfall system development model, which consists of analysis, design, implementation, and testing. Data Analysis. Metadata obtained from the repository application, distributing questionnaires to students taking Thesis/Final Project courses from each faculty. Results and Discussion. The literacy level of Banten Jaya University students is quite good, especially after the online repository has been built, there is a significant correlation between student literacy levels and student performance results. Conclusions and suggestions. A good literacy level is the basic capital in solving student problems while doing their research, it is necessary to have a Research Information Literacy program for students that is integrated with Research Methods courses so that student research performance increases in accessing the repository that has been built.

Abstract

TThis study aims to cluster laptop price data using the K-Means algorithm to obtain a more structured and interpretable price segmentation. The data used in this study consist of laptop price data that have undergone a preprocessing stage, including data cleaning, data transformation, and data normalization to ensure optimal data quality. The determination of the optimal number of clusters was conducted using the Elbow Method by analyzing the Within Cluster Sum of Squares (WCSS) values, which indicated that the optimal number of clusters is k = 3. Subsequently, the K-Means algorithm was applied to group the laptop price data into three clusters based on price characteristics. The clustering results reveal three main groups, namely low-price, mid-price, and high-price laptop clusters. This segmentation provides a clear overview of the laptop market conditions and highlights the differences in price ranges among the clusters. The results demonstrate that the K-Means algorithm is able to cluster laptop price data effectively and consistently. The resulting segmentation can be utilized as a basis for decision-making for consumers as well as business stakeholders in developing marketing strategies and determining appropriate laptop pricing

Abstract

The Serang Regency Environmental Agency carries out government duties in the environmental sector in accordance with the Regional Medium-Term Development Plan in the Regional Medium Term Development Plan (RPJMD). The high volume of correspondence (incoming and outgoing mail) presents a significant performance challenge. Given that the mail management process—from receipt, creation, storage, and documentation—is still performed manually, a solution is needed. Therefore, a Letter Archive Information System developed using PHP and MySQL is crucial. This system functions to record and track all mail, aiming to simplify the process and save time and effort spent searching for archived data. After implementation, this system successfully helped administrators overcome the difficulties of inputting letter data, which was previously done manually. In conclusion, this letter archive system improved overall work efficiency, made data input more effective and efficient, and achieved high levels of satisfaction from administrators.
