This study aims to analyze the influence of Product Quality, Price, Sales Promotion, and Advertising on consumer purchasing decisions on the Bukalapak online store platform. This study used a quantitative approach with descriptive methods, aiming to illustrate the relationships between variables based on empirical data. Primary data were obtained by distributing questionnaires to 120 respondents who were active Bukalapak users in the West Medan District. The data analysis technique used was multiple linear regression with the aid of SPSS software to determine the effect of each independent variable on the dependent variable. The analysis results indicate that, partially, the variables Product Quality, Sales Promotion, and Advertising have a positive and significant influence on purchasing decisions. This means that the higher the product quality, the more effective the promotion, and the more attractive the advertisement, the greater the likelihood of consumers making a purchase. Conversely, the variable Price showed a negative and significant influence, indicating that inappropriate pricing can reduce purchase intention. Simultaneously, all four variables have a significant influence on purchasing decisions. The Adjusted R Square value of 70.4% indicates that this research model is able to explain 70.4% of the variation in purchasing decisions, while the dependent variable is influenced by factors outside the model. This study recommends that Bukalapak continue to improve product quality, develop competitive pricing strategies, strengthen promotions, and create creative advertising. Further research is recommended to consider additional variables such as product reviews, brand image, and service quality to enrich the analysis.

This study discusses the utilization of service progress operational activities at PT PAL Indonesia. The purpose of this study is to evaluate how well the current procedures are implemented and to identify any obstacles that arise during the process of submitting and accounting for service advances. A descriptive qualitative methodology was used, with data collected through observation, interviews, and documentation. The findings indicate that the procedures for submitting and reporting service advance payments have been carried out in a structured manner, supported by the digital IM4 system and a layered verification mechanism to minimize errors. However, challenges remain, such as delays in fund disbursement due to budget limitations, which impact the timely execution and reporting of activities. The use of digital technology has proven to enhance efficiency and transparency in managing operational finances. This research provides valuable insights for the development of a more effective and timely service advance management system, while also emphasizing the importance of budget strengthening and employee training to support smooth operations.

Kemajuan teknologi informasi mendorong perubahan sistem pendidikan, termasuk kebijakan perkuliahan online sejak pandemi COVID-19. Penelitian ini menganalisis sentimen mahasiswa terhadap kebijakan tersebut menggunakan pendekatan multibahasa dengan algoritma K-Nearest Neighbor (KNN) dan Naïve Bayes. Adapun aspek pembeda penelitian ini adalah penggunaan data dari bahasa Indonesia dan bahasa daerah Sulawesi Barat, yaitu bahasa Mandar, yang menambah kompleksitas tahap preprocessing. Data dikumpulkan melalui kuesioner yang menghasilkan 1.680 opini mahasiswa, dan setelah tahap preprocessing menghasilkan 1.679 data yang siap dianalisis. Hasil klasifikasi menunjukkan algoritma K-Nearest Neighbor terdapat 1002 kategori positif dan 677 kategori negatif. Kemudian pada algoritma Naïve Bayes terdapat 1020 kategori positif dan 659 kategori negatif. Berdasarkan hasil klasifikasi, mayoritas opini bersifat positif, mencerminkan bahwa mahasiswa menerima adanya kebijakan tersebut. Hasil evaluasi melalui confusion matrix serta K-Fold Cross Validation menunjukkan bahwa pendekatan klasifikasi Naïve Bayes mengungguli KNN dengan accuracy 74.87%, precision 74.92%, recall 74.87%, dan f1-score 74.64%. Sementara itu, KNN mencatat accuracy 72.84%, precision 72.80%, recall 72.84%, dan f1-score 72.67%. Hal tersebut mengindikasikan bahwa Naïve Bayes mempunyai kemampuan generalisasi yang lebih unggul pada konteks data teks multibahasa yang kompleks. Penelitian ini menyoroti pentingnya strategi evaluasi dan teknik preprocessing yang sesuai dalam klasifikasi sentimen multibahasa.

The social conflict that occurred in Negeri Masihulan, Central Maluku Regency, in April 2025, resulted in dozens of residents' houses burning down and had serious psychological impacts, especially for children. Children as a vulnerable group experience fear, anxiety, and trauma due to conflict and displacement situations. This community service aims to provide psychosocial assistance through trauma healing as an effort for non-litigation legal protection for child victims of social conflict. This activity was carried out using the approach of playing, drawing, telling stories, and praying together, attended by 30 children aged 5-13 years. The results of the activity showed positive changes in the emotional condition of children, a growing sense of security, and an increased spirit of togetherness after the conflict. Trauma healing has proven to be an effective instrument in psychological recovery as well as a form of implementation of community-based legal protection. It is hoped that this activity will become a model in handling child victims of conflict in areas prone to social conflict in Maluku.

Pragmatics, a fundamental branch of linguistics, focuses on the implicit rules that govern human interaction. It delves into how meaning is constructed, conveyed, and interpreted in everyday communication beyond literal language. This study explores the mechanisms of pragmatics in daily life, particularly how context, shared knowledge, and social conventions influence interactions. Key areas examined include speech acts, implicature, and politeness strategies, which highlight the dynamic nature of meaning-making in various social contexts. Speech acts, such as requests, apologies, and promises, illustrate how utterances perform actions beyond their lexical content. Implicature examines how individuals infer meaning that is not explicitly stated, relying on context and shared assumptions. Politeness strategies, which vary across cultures, play a crucial role in managing interpersonal relationships and ensuring smooth communication by balancing social expectations and individual intentions. Understanding these unspoken rules is essential for effective communication, as they often dictate the success of social interactions. Misinterpretations in pragmatics can lead to misunderstandings, social faux pas, or conflicts, emphasizing the importance of cultural and contextual awareness. Pragmatic competence is crucial in multilingual and multicultural settings, where differing conventions and norms can create unique challenges. By synthesizing theoretical insights from existing literature, this study highlights the pervasive influence of pragmatics in shaping human interaction. It underscores the necessity of pragmatic awareness in fostering interpersonal understanding, enhancing communication skills, and navigating the complexities of social life effectively.

Kampung Depet Indah is one of the villages in the Celala District, Central Aceh District. Kampung Depet Indah is located in an area that is remote in the District of Celala with its vast natural potential with agricultural land and plantations. Based on the results of surveys conducted on several farms and plantations, there are still many farmers who on average use chemical fertilizers as a source of additional or substitute nutrients needed by plants to support growth. One of the work programs being carried out is the manufacture of liquid organic fertilizer (POC) from banana peel waste, where POC itself is a liquid organic fertilizer that can be used by farmers as a provider of nutrients for plants and crops. The implementation of making POC up to the socialization stage to the community consists of several stages which include: (1) Preparation of tools and materials (2) Making POC as a sample (3) Making POC posters (4) Socializing POC to the community (5) Question and answer session.
