Abstract

Efficiently classifying public complaints is crucial for fostering transparent and responsive governance in the digital age. However, the sheer volume and textual nature of complaint data pose significant challenges for manual categorization, particularly within local government systems. This study seeks to develop an automatic classification model for public complaints by employing Logistic Regression and TF-IDF vectorization. The dataset, comprising complaints submitted to the Karanganyar Regency Government from January to June 2025, underwent preprocessing through standard natural language techniques and was converted into numerical features using TF-IDF. Logistic Regression was chosen for its simplicity, interpretability, and effectiveness with sparse text data. To address class imbalance, class weighting and stratified sampling were utilized. The model achieved an overall accuracy of 61%, surpassing the Naive Bayes baseline. Confusion matrix analysis demonstrated strong performance in dominant categories, although minority classes continued to present challenges. The results suggest that Logistic Regression offers a practical and explainable solution for early-stage complaint classification systems, especially in public sector contexts. This study lays the foundation for the future development of intelligent e-government platforms capable of real-time complaint handling.

Abstract

Background: The hospitality industry is highly competitive and continuously seeks strategies to attract and retain customers. Multisensory marketing, which engages all five senses, has emerged as an effective way to enrich the guest experience and to foster loyalty. Objective: This study examines how multisensory strategies influence customer loyalty at a five-star hotel in Surabaya, focusing on key loyalty metrics, including repeat visits, willingness to recommend, and emotional attachment. Method: A qualitative approach was employed through in-depth interviews with hotel staff and real guest participants. Data were coded using a structured thematic framework, with illustrative raw excerpts included to ensure transparency. Ethical approval was obtained, and informed consent was secured from all participants. Results: The findings reveal that the hotel's multisensory applications—including visual ambiance, signature scents, curated soundscapes, and diverse culinary experiences—enhance customer satisfaction and contribute to loyalty patterns. Visualized results as presented in the thematic tables and charts, highlight the key links between sensory engagement and loyalty behaviors. Conclusion: Multisensory strategies effectively create memorable, emotionally engaging guest experiences, strengthening loyalty by increasing satisfaction, repeat patronage, and advocacy. These findings underscore the value of integrating multisensory marketing as a sustainable competitive advantage in luxury hospitality. Keywords: Customer Loyalty; Multisensory Marketing; Hospitality Strategy; Guest Experience; Sensory Branding; Emotional Engagement.

Abstract

Corruption is a bureaucratic disease that has become as entrenched as the common cold, undermining governments globally. Proactive government policies can reduce corruption crimes through prosecution, prevention and education. The Indonesian government has implemented a ‘trident’ corruption eradication policy in educational institutions aiming to shape the attitudes, norms and behaviour of the nation’s younger generation. Unfortunately, the existing literature is limited in assessing the policy output of preventing and eradicating corruption, particularly the effectiveness of anti-corruption education among university students. A policy output evaluation perspective is offered to fill this research gap. This study aims to evaluate the policy output of anti-corruption education in shaping attitudes, norms and behaviour using the theory of planned behaviour. A quantitative approach and survey method were chosen, and a total of 125 respondents participated. The partial least squares algorithm and bootstrapping methods were used to analyse the data. The study’s results reveal that perceived behaviour control, attitude, subjective norm have significant influences on students’ intention. Perceived behaviour control has significant influences on students’ anti-corruption behaviour, though attitudes do not affect students’ anti-corruption behaviour. The findings also show that it has a good level of effectiveness in anti-corruption education policy outputs in achieving policy goals. Our policy recommendations include socialisation about anti-corruption to the community, implementing ideology education and upholding the law on corruption to increase the success of corruption prevention and eradication policies.

Abstract

Artikel ini membahas prinsip fundamental dalam sistem hukum yang menekankan keadilan, kemanfaatan, dan kepastian hukum, khususnya dalam konteks hukum perjanjian dan peran notaris sebagai pejabat umum. Akta autentik yang dibuat oleh notaris memiliki kedudukan istimewa karena memberikan kekuatan pembuktian sempurna dan menjadi instrumen penting dalam menjamin kepastian hukum. Namun, untuk menjaga kredibilitas dan profesionalisme notaris, pengawasan negara melalui Majelis Pengawas Notaris (MPN) menjadi keharusan. Penelitian ini menitikberatkan pada peran Majelis Pengawas Daerah (MPD) sebagai ujung tombak pengawasan di tingkat kabupaten/kota. MPD memiliki kewenangan melakukan pembinaan, pengawasan, serta pemeriksaan atas dugaan pelanggaran jabatan notaris. Dengan metode penelitian yuridis normatif menggunakan pendekatan perundang-undangan dan konsep, penelitian ini menegaskan bahwa pembinaan oleh MPD bertujuan menjaga martabat profesi notaris, sedangkan pengawasan berfungsi mencegah penyalahgunaan kewenangan. Kesimpulannya, MPD berperan strategis dalam memastikan notaris menjalankan tugas sesuai kode etik dan peraturan perundang-undangan, sehingga hak masyarakat atas pelayanan hukum yang adil, transparan, dan pasti dapat terlindungi.

Abstract

Penelitian ini bertujuan untuk menganalisis secara kritis syarat dan pemenuhan hukum terhadap pemutusan perjanjian yang dilakukan secara sepihak berdasarkan Kitab Undang-Undang Hukum Perdata (KUH Perdata) Indonesia. Pemutusan perjanjian secara sepihak kerap menimbulkan ketidakpastian hukum dan merugikan salah satu pihak karena bertentangan dengan asas pacta sunt servanda yang mengikat perjanjian sebagai undang-undang bagi para pihak. Metode yang digunakan adalah penelitian hukum normatif dengan pendekatan perundang-undangan dan pendekatan konseptual. Sumber bahan hukum terdiri dari bahan hukum primer (KUH Perdata), bahan hukum sekunder (buku teks, jurnal hukum, dan doktrin), serta bahan hukum tersier (kamus hukum dan artikel daring). Teknik analisis yang digunakan adalah deskriptif-analitis dan interpretasi teks hukum.Hasil penelitian menunjukkan bahwa pemutusan perjanjian secara sepihak hanya dapat dibenarkan apabila didasarkan pada kesepakatan para pihak dalam klausul perjanjian, atau alasan yang secara tegas ditentukan oleh undang-undang, seperti wanprestasi yang dibuktikan melalui somasi dan putusan hakim (Pasal 1266 KUH Perdata). Apabila pemutusan sepihak dilakukan tanpa dasar hukum yang sah, tindakan tersebut dapat dikualifikasikan sebagai wanprestasi (Pasal 1243 KUH Perdata) atau sebagai perbuatan melawan hukum (Pasal 1365 KUH Perdata), tergantung pada ada tidaknya hubungan perjanjian dan pemenuhan unsur kesalahan serta kerugian. Oleh karena itu, pemutusan perjanjian wajib memperhatikan asas itikad baik, kepatutan, dan kepastian hukum guna melindungi hak-hak para pihak.
