Abstract

Industri konveksi menghadapi tantangan dalam menentukan jumlah produksi bahan dasar akibat fluktuasi permintaan pasar dan keterbatasan bahan baku. Penelitian ini bertujuan untuk menerapkan algoritma klasifikasi C4.5 sebagai solusi prediktif berbasis data mining untuk mendukung pengambilan keputusan produksi di CV. Eternal Group. Dengan menggunakan data historis bulan Maret–Agustus 2024, sistem dirancang melalui tahapan preprocessing, perhitungan entropy dan gain ratio, serta pembentukan pohon keputusan. Hasil klasifikasi menunjukkan bahwa atribut “Permintaan Pasar” memiliki pengaruh dominan terhadap keputusan produksi, diikuti oleh “Ketersediaan Bahan Baku” dan “Tren Penjualan.” Sistem dikembangkan menggunakan PHP dan MySQL, dan diuji melalui aplikasi yang menghasilkan tingkat akurasi tinggi berdasarkan evaluasi confusion matrix. Penelitian ini tidak hanya menghasilkan sistem prediksi yang adaptif dan akurat, tetapi juga memberikan kontribusi terhadap efisiensi operasional, pengurangan pemborosan bahan baku, serta pemahaman yang lebih baik terhadap preferensi pasar. Dengan demikian, penerapan algoritma C4.5 terbukti efektif dalam mendukung strategi produksi yang lebih terukur dan responsif dalam industri konveksi.

Abstract

In this community service activity we are developing an internet network that will be used by schools in rural areas, one of the areas in Stabat City in building this internet network we use the ubnt antenna which is reliable in spreading signals in the countryside and our goal is to build an internet network in the village, namely to help the community in obtaining information that is currently very fast and the obstacles that the surrounding community has are very difficult to connect to the internet network after the team pays attention to the problem because of the large number of palm trees that make it very difficult to get a signal in the village and even the school when the school is very fast. The obstacle that the village has is that the signal in the village is not up to 2 bars so that the surrounding community is very difficult to connect to the internet network after the team noticed the problem because of the large number of palm trees which made the signal very difficult to get by local residents and even schools currently have difficulty in the learning process, let alone accessing dapodik owned by the school which must be connected to the internet network.

Abstract

This community service program aims to enhance the capacity of micro, small, and medium enterprises (MSMEs) in Aek Pamingke Village in utilizing artificial intelligence (AI) for data-driven digital marketing strategies. The activities were conducted through several stages, including needs analysis, intensive training, practical implementation, and evaluation. The initial analysis revealed that most MSME participants had limited knowledge and skills in digital marketing, with 60% categorized as having low understanding before the program. After the training, significant improvement was recorded, with 50% of participants reporting being very satisfied and 35% satisfied. The program’s impact was evident in the participants’ improved ability to design more effective data-driven marketing strategies. The main limitations of this program were the relatively small number of participants and the limited implementation time, indicating the need for extended programs with broader coverage in the future.

Abstract

The rapid development of fiber-optic–based internet technology has led to an increasing demand for stable and evenly distributed WiFi networks. Although internet service providers such as XYZ have established extensive fiber-optic infrastructure, challenges in WiFi access point distribution remain common, particularly regarding uneven network coverage and limited data-driven analysis. These issues raise the question of how to determine optimal WiFi deployment locations to ensure consistent service quality. Therefore, this study aims to analyze the spatial distribution patterns of XYZ’s WiFi network based on fiber-optic connection points, apply the Extreme Gradient Boosting (XGBoost) algorithm to classify the feasibility of WiFi distribution, and evaluate the performance of the proposed model in improving network distribution efficiency. This research employs XGBoost as a classification method to predict suitable and unsuitable WiFi deployment locations using customer data connected via fiber-optic cables. The study focuses on data preprocessing, model construction using XGBoost, performance evaluation in classifying feasible and non-feasible locations, and data balancing techniques to address class imbalance. The dataset consists of 193 XYZ customer records, divided into 80% training data and 20% testing data. The results demonstrate that the XGBoost algorithm achieves high classification accuracy in WiFi network distribution. Consequently, the proposed model can serve as a data-driven recommendation tool for optimizing WiFi deployment, enabling service providers to deliver more evenly distributed, stable, and efficient internet services

Abstract

Advances in technology and information today can produce a smart innovation in business, which we can call business intelligence. In this technological advancement is the use of previous data which will later be used to obtain a data update to increase sales of a product in this case the technique is called a data mining technique which can extract useful information from the sales data warehouse. The use of data mining techniques is expected to help speed up the decision-making process,enabling decision-makers to manage the information contained in transaction data into new knowledge. Therefore the seller must be more careful in providing the type of product, in this case the researcher conducts research on the sale of catfish which will be in great demand, so that the seller will be able to provide recommendations for the type of catfish that has the most demand, so that the seller can classify types of catfish from the type, price, and weight of the catfish using aclassification method carried out using the C4.5 data mining algorithm. The C4.5 algorithm is a tree data type decision classification algorithm. The decision tree C4.5 algorithm is built in several stages which include selecting the attribute as the root, creating a branch for each value and dividing the case on the branch. This step will be repeated for each branch until all cases in the branch have the same class. From the results of tree testing of decision search results from sales datausing the RapidMiner Studio application, the results that have the highest gain in predicting catfish sales are weight and type so that it will produce the status of selling catfish in demand and those that are not selling by giving a value of >= 25 in katakana in demand. and <25 are said to be not selling well, so the Galatama pond manager can make a reference to pay attention to these two variables in selling catfish to get the best sales.

Abstract

This study addresses the limitations of existing decentralized e-voting systems, particularly their reliance on public distributed infrastructures, limited real-world deployment feasibility, and lack of comprehensive evaluation. Previous studies have demonstrated the potential of distributed ledger-based voting mechanisms; however, most focus on conceptual designs or small-scale prototypes without detailed performance and usability validation. To address this gap, this research proposes and implements a decentralized e-voting system deployed on a local server infrastructure using distributed ledger technology and automated validation mechanisms for vote integrity. The system is designed to reduce dependency on external networks while maintaining transparency, immutability, and operational efficiency. The system was evaluated through functional testing, performance analysis, and user acceptance testing involving 30 participants in a controlled environment with 20 simulated voters. The results show that the system achieved a functional accuracy of 96% across 25 test scenarios. The average transaction response time ranged between 0.6 and 1.6 seconds, indicating efficient processing under moderate load conditions. However, the evaluation is limited to small-scale simulations and does not include stress testing, large-scale scalability analysis, or advanced security validation. Therefore, the findings demonstrate system feasibility rather than fully validated effectiveness. These results suggest that decentralized e-voting systems deployed on local infrastructures can provide a practical and efficient solution for controlled election environments, while further research is required to evaluate scalability, security robustness, and real-world deployment readiness.
