This article discusses the implementation of PrestaShop in website development, marketing and logistics at the SS Galery Rantauprapat store. PrestaShop is an e-commerce platform designed to make it easier to create and manage online stores with features that support sales, including product management, payment systems, and sales analysis. In the context of SS Gallery, the implementation of PrestaShop aims to increase operational efficiency and expand market reach. The implementation process begins with designing a website that is responsive and user-friendly, allowing customers to access product information easily. The e-marketing features in PrestaShop are also used to increase product promotions, attract more customers and increase their loyalty. In addition, an integrated logistics system helps in managing goods delivery efficiently, reducing customer waiting time. The results of this research show that using PrestaShop not only increases sales productivity but also simplifies the marketing process and logistics management. In this way, SS Galery Rantauprapat can compete better in an increasingly competitive digital market. This research provides insight for other business actors about the importance of information technology in supporting business growth in the digital era.

The development of today's increasingly advanced technology such as the use of computers has become popular in the community, the use of computers is very important because the computer is a tool in carrying out data processing activities, so that a job can be completed properly. How the distribution of rice for the poor can work properly using this application. The purpose of the study is to assist the process of distributing rice for the poor at the Sirandorung Village Office. The system analysis stage is a very important stage because errors at this stage will result in errors in the next stage. In analyzing the system, several methods are used, among others. Based on the results of research and discussion that the results of the analysis of the implementation of the distribution of rice for poor households (Raskin) in Sirandorung Village, Rantau Utara District, Labuhanbatu Regency, the implementation is still not precise and has not been implemented properly. This is based on the analysis above and based on the results of questionnaires and interviews with researchers from the Sirandorung sub-district office. All people in the Sirandorung sub-district should be collected and provided with detailed information about the Raskin program so that there is no misunderstanding or receiving inaccurate information about Raskin.

Gubernur DKI Jakarta saat ini, meski sudah terpilih sejak tahun 2017 selalu menarik untuk dibicarakan atau bahkan dikomentari. Komentar yang muncul berasal dari media secara langsung atau melalui media sosial. Twitter menjadi salah satu media sosial yang sering digunakan sebagai media untuk mengomentari gubernur terpilih bahkan bisa menjadi trending topic di media sosial Twitter. Netizen yang berkomentar pun beragam, ada yang selalu menge-Tweet kritik, ada yang berkomentar Positif, dan ada pula yang hanya me-retweet. Dalam penelitian ini, prediksi apakah Netizen aktif akan cenderung selalu menimbulkan komentar Positif atau Negatif akan dilakukan dalam penelitian ini. Model algoritma yang digunakan adalah Decision Tree, NaÃ¯ve Bayes, Random Forest, dan juga Ensemble. Data Twitter yang diolah harus melalui preprocessing terlebih dahulu sebelum dilanjutkan menggunakan Rapidminer. Dalam uji coba menggunakan Rapidminer dilakukan dalam empat kali uji coba dengan membagi menjadi dua bagian yaitu data testing dan data latih. Perbandingan yang dilakukan adalah 10% data pengujian: 90% data pelatihan, kemudian 20% data pengujian: 80% data pelatihan, kemudian 30% data pengujian: 70% data pelatihan, dan yang terakhir adalah 35% data pengujian: 65% data pelatihan. Rata-rata Akurasi untuk algoritma Decision Tree adalah 93,15%, sedangkan untuk algoritma NaÃ¯ve Bayes Akurasinya adalah 91,55%, kemudian untuk algoritma Random Forest adalah 93,41, dan yang terakhir adalah algoritma Ensemble dengan Akurasi sebesar 93,42%. sini. 65% data pelatihan.

This study aims to analyze consumer purchasing patterns in minimarkets using the Apriori and Fp Growth association algorithms based on transaction data, where the data consists of 10 goods receipt transactions with 7 variable items such as Ultra Milk UHT 250ml, Indomie Goreng Spesial, Beras Ramos 5kg, Teh Cup Sariwangi 25's, Minyak Goreng Bimoli 1L, Soap Bar Lifebuoy 75g, and Mie Lemonilo Goreng 70g. The analysis process is carried out through the preprocessing stage, transformation to binary format, and application of the algorithm with minimum support parameters of 20% and confidence of 50%. The results show that Ultra Milk UHT 250ml has the highest support (0.5) followed by Indomie Goreng Spesial (0.4), while the combination of UHT Milk with Indomie has a support of 0.2; in terms of confidence, a number of rules even reach a perfect value of 1.0, for example the relationship between Teh Cup Sariwangi and Ultra Milk which always appear together. Quantitatively, Apriori produces 25 association rules with a processing time of approximately 2.1 seconds, while Fp Growth produces the same number of rules but is more efficient with a processing time of 1.3 seconds and lower memory usage, so it can be concluded that although both are equal in terms of rule quality, Fp Growth is superior in computational efficiency. This finding has important practical implications for minimarket management, especially to support shelf arrangement strategies, more targeted stock planning, and the preparation of bundling promotions based on product combinations with high confidence, while also showing a scientific contribution in the form of comparing the performance of two association algorithms on incoming goods data that is relatively rarely used in previous studies.

The growing automotive industry demands workshops to improve the quality of service for customer satisfaction. However, manual measurement of satisfaction is often inefficient and subjective. This study proposes the application of machine learning algorithms K-Means Clustering to analyze customer satisfaction data in Rizal workshop. This method is used to Group customers into several clusters based on similar satisfaction characteristics. The results of this grouping are expected to provide more objective and in-depth insights to identify patterns of satisfaction, thus enabling the workshop to formulate a more effective and targeted service quality improvement strategy.

This study was conducted to classify public satisfaction levels using the Support Vector Machine (SVM) algorithm as the primary data analysis method. The objective of this study was to obtain an accurate and reliable prediction model for determining the Satisfaction and Dissatisfaction categories based on the available data. The theoretical basis used refers to the concept of machine learning, specifically SVM, which works by forming an optimal hyperplane to separate data classes. In addition, model evaluation theories such as the Confusion Matrix were used to objectively measure prediction performance. The research methodology included data collection, pre-processing, dividing the dataset into training and test data, and training the SVM model. Evaluation was conducted using accuracy, sensitivity, and specificity metrics to assess the model's ability to predict data accurately. The results and discussion indicate that the SVM successfully classified the majority of data correctly, with the Satisfaction class having a perfect prediction rate while the Dissatisfaction class still had a small error. Further analysis indicated the need for SVM parameter optimization to improve accuracy in the minority class. The conclusion of this study states that the SVM has good performance in classifying public satisfaction data, although it still requires refinement in recognizing certain class patterns. This finding opens up opportunities for developing more adaptive methods to improve predictive performance.
