Penerapan Algoritma Naive Bayes pada Analisis Sentimen Ulasan Aplikasi Whoosh – Kereta Cepat Di Google Play Store
Sentiment analysis of user reviews on mobile app distribution platforms is a complex and crucial issue, especially with the rapid growth of the number of users and the volume of reviews. This research focuses on the application of Naive Bayes Algorithm to analyze the sentiment of user reviews of WHOOSH app on Google Play Store. Naive Bayes algorithm was chosen due to its efficiency and easy implementation. Using a dataset of 500 cleaned and labeled reviews (positive or negative), the model was trained and achieved 81.25% accuracy. The high precision for the positive class (90%) demonstrates the model's ability to correctly identify positive reviews. Although the recall of the positive class is high (94%), the recall of the negative class still needs to be improved (64%). Overall, the Naive Bayes model is effective for classifying sentiment in WHOOSH user reviews, but needs to improve the accuracy and recall of negative classes

CIPP EVALUATION MODEL IN LEARNING IN MADRASAH IBTIDAIYAH
This research aims to describe the CIPP evaluation model at Madrasah Ibtidaiyah. The research uses a type of library research with a content analysis method to explore data that has been collected through the Google Scholar database and books in online libraries related to the topic being studied. The research results show that the CIPP evaluation model is carried out comprehensively to understand the activities of a particular program, starting from the emergence of the idea to the results obtained from the program created. The basic concept of the CIPP model is to evaluate several components including context, input, process and product. The CIPP model has several objectives including context evaluation to serve planning decisions, input evaluation, structuring decisions, process evaluation, to serve implementing decisions, product evaluation, to serve recycling decisions. Compared to other evaluation models, the CIPP model has several advantages, namely being more comprehensive, having a holistic approach, having the potential to move in the area of formative and summative evaluation, being able to provide a good basis for making decisions and policies as well as preparing further programs. However, apart from these advantages, of course there are also disadvantages. The shortcomings of the CIPP evaluation model are that it is too concerned with where the process should be rather than the reality in the field, tends to focus on rational management, application in the field of classroom learning has a low level of implementation
Program Pendaftaran Tanah Sistematis Lengkap (PTSL) Oleh Badan Pertanahan Nasional Di Surabaya
Pelaksanaan pendaftaran tanah tiap daerah merupakan tanggung jawab pemerintah yang menjelaskan salah satunya kegunaan sertifikat tanah, yaitu untuk memberikan kepastian hukum dan perlindungan hukum kepada pemegang hak atas suatu bidang tanah, satuan rumah susun dan hakhak lain yang terdaftar agar dengan mudah dapat membuktikan dirinya sebagai pemegang hak yang bersangkutan. Tujuan penelitian untuk mengetahui dan menganalisis Program Pendaftaran Tanah Sistematis Lengkap (PTSL) oleh Kantor Badan Pertanahan Nasional Kota Surabaya dan manfaat yang terjadi. Metode yang hendak digunakan dalam penelitian ini adalah metode penelitian yuridis normatif menggunakan pendekatan perundang-undangan. Hambatan dalam pelaksanaannya seperti belum tercapainya tujuan dalam pencapaian target Sertifikat Hak Atas Tanah (SHAT), karena banyak pemohon yang belum terdaftar, kurangnya fasilitas untuk pelaksanaan pendaftaran dan kurangnya komunikasi antara kantor BPN dan masyarakat yang kurang paham mengenai adanya program PTSL. Untuk mengatasi hambatan tersebut, yaitu dengan mengaktivasikan NIK yang tidak valid agar dapat mengajuakan pemberkasan untuk pendaftaran program PTSL, mengoptimalkan proses pemberkasan dari pihak Desa agar pengentrian oleh staf kantor BPN bisa segera dilakukan dan cepat selesai
PENGARUH VARIASI CAMPURAN 2,5-DIMETHYLFURAN- MINYAK KELAPA PADA PEMBAKARAN DROPLED TERHADAP PERILAKU NYALA API
Tujuan dari penelitian ini untuk mengetahui pengaruh variasi campuran 2,5-dimethylfuran- minyak kelapa pembakaran droplet terhadap evolusi nyala api, tinggi nyala api dan emisi hydrocarbon. Minyak nabati dan turunannya serta penambahan bioaditif 2,5-dimethylfuran sangat dibutuhkan untuk dilakukan penelitian sebagai pengganti bahan bakar fosil. Bahan bakar menggunakan variasi campuran 2,5-dimethylfuran-minyak kelapa. Dilakukan penelitian secara eksperimental dengan menempatkan sebuah tetesan campuran 2,5-dimethylfuran- minyak kelapa pada thermocouple type K dengan diameter tetesan 0.3 mm. Hasil penelitian menemukan campuran 2,5-dimethylfuran 15%-minyak kelapa bahwa bahan bakar mudah menguap disebabkan nilai viskositas 2,5-dimethylfuran lebih rendah daripada minyak kelapa. Sehingga molekul bahan bakar bergerak sangat leluasa menghasilkan proses nukleasi pada droplet menjadi lebih singkat. Adanya senyawa 2,5-dimethylfuran yang menghasilkan ikatan baru itu berpotensi meningkatkan panjang karbon rantai minyak kelapa. Dampaknya jarak antar molekul bahan bakar menjadi lebih kecil, sehingga kemungkinan untuk efektif tabrakan sangat besar. Fenomena ini dapat meningkatkan reaktivitas molekul bahan bakar sehingga mudah terbakar dan laju pembakaran difusi meningkat menghasilkan nyala api bulat, tinggi nyala api rendah dan emisi hydrocarbon menurun dan lebih stabil dibandingkan dengan campuran 2,5-dimethylfuran lainnya
