Abstract

Public administrative service quality is a crucial factor in citizen satisfaction. This study analyzes sentiment in public service reviews using a text mining approach with the Naïve Bayes Classifier method. The dataset was collected from citizen feedback on online platforms regarding public administrative services. Preprocessing steps included tokenization, case folding, stopword removal, and stemming. The Naïve Bayes algorithm with Laplace smoothing was applied for classification, and performance was evaluated using accuracy, precision, recall, and F1-score. The experiment resulted in an accuracy of 91.2%, precision of 90.3%, recall of 89.7%, and F1-score of 90.0%. The analysis revealed that Service Speed obtained an average score of 3.21, indicating a moderate level of citizen satisfaction in that aspect. These findings suggest that while the Naïve Bayes method is effective for sentiment classification, its greatest value lies in providing actionable insights for public service improvement. Specifically, policymakers can prioritize addressing delays in service speed through simplified procedures, improved staffing, and digital innovation, while maintaining strengths such as officer politeness and effective complaint handling. By leveraging sentiment analysis, public institutions can continuously monitor citizen feedback, identify problem areas, and implement evidence-based strategies to enhance service quality and strengthen public trust.

Abstract

Dalam meningkatkan eksistensi suatu instansi ke masyarakat luas, perlu adanya suatu media yang dapat menjadi salah satu sarana promosi. Promosi yang banyak diterapkan saat ini yaitu dalam bentuk video profil. Video profil merupakan sebuah media elektronik untuk menyampaikan informasi yang efektif dalam memperkenalkan dan promosikan suatu instansi.TK Islam Al Mujahidin merupakan salah satu sekolah Taman Kanak-Kanak yang terletak di Kota Semarang yang sampai saat ini belum memiliki media promosi dalam bentuk video profil. Berdasarkan hal tersebut, maka untuk melakukan promosi, perlu dikembangkan sebuah video profil TK Islam Al Mujahidin.Dalam pembuatan video ini, digunakan peralatan pendukung, seperti kamera, lighting, aplikasi editing video, dan pendukung lainnya, sehingga akan memudahkan pembuatan video profil. Dalam pembuatan Video Profil tahapan yang akan dibuat dimulai dari tahap Pra Produksi (persiapan ide, pengerjaan video, dan dialog atau storyboard), Tahap Produksi (proses pengambilan gambar), tahap Paska Produksi (Editing Video) serta elemen-elemen yang ada setiap tahapnya. Hasilnya berupa video profil yang dapat digunakan untuk mempromosikan TK Islam Al Mujahidin.

Abstract

This study aims to measure student satisfaction with boarding houses or contracts. To achieve this goal, the authors implement the C4.5 algorithm in data analysis. Data on student satisfaction was taken through a survey covering various factors related to price, facilities, strategic layout, and the quality of the boarding house or contract. Algorithm C4.5 is used to produce a decision-making model based on criteria that are relevant to the level of student satisfaction. The results of this model provide valuable information in understanding what factors most influence student satisfaction with boarding houses or contracts. The results showed that the C4.5 algorithm was successful in building a model capable of classifying the level of student satisfaction with boarding houses or contracts with high accuracy. The results of this study are expected to help boarding or contract parties to increase student satisfaction. In addition, this research can also be a basis for further research in the field of student satisfaction and the application of the C4.5 algorithm to similar problems.

Abstract

This study aims to design and implement a Decision Support System (DSS) to optimize the management of finished goods inventory at PT. Hesed Indonesia using the Economic Order Quantity (EOQ) method. In the manufacturing industry, one of the main challenges in the supply chain is maintaining the availability of finished goods at optimal levels to avoid overstocking which results in excessive storage costs and understocking, which can impede distribution processes. To address this challenge, the EOQ method is employed for its effectiveness in determining optimal order quantities, annual demand, and per-unit storage costs. This research adopts a case study approach with a quantitative methodology. The data collected includes annual demand for finished goods, ordering costs, and storage costs provided by the company. The processed data using the EOQ formula serves as the basis for developing a system capable of generating recommendations for optimal order quantities and ordering frequencies. The DSS is designed to deliver timely and accurate information to assist managerial decision-making regarding inventory control. The results demonstrate that the implementation of the EOQ-based DSS significantly reduces total inventory costs and enhances the company’s operational efficiency. Moreover, the system facilitates data-driven decision-making and minimizes subjectivity in inventory management. With the implementation of this system, PT. Hesed Indonesia is expected to manage its finished goods inventory more effectively and adaptively in response to market demand fluctuations.
