The case in this study is the decline in grain prices in early to mid-2021. This study aims to determine the percentage of sentiment polarity that appears when associated with the keyword price of grain and determine the level of accuracy of sentiment class predictions using the Naïve Bayes method. The results showed that the largest percentage of sentiment was negative as much as 46.30%, neutral 32.70% and positive as much as 20.99%. The results of the wordcloud also show that twitter users link the issue of grain prices to rice imports, the role of the government and fertilizers.

These tourist reviews can influence and consider other potential tourists who will visit these attractions. One of the popular travel platforms is TripAdvisor. Reviews on this platform regarding Mount Bromo tourism objects are analyzed further so that the tourism object managers can get information that can be used as the basis for developing the tourism objects they manage. Sentiment analysis with a classification approach with a supervised learning algorithm can be used as a method to explore tourist sentiment which is positive or negative sentiment. Of the three classification algorithms tested in this study, the Decision Tree algorithm has the highest accuracy rate of 91%, followed by Naïve Bayes and Logistic Regression, each with 88%. The precision, recall, and f1-measure levels for the Decision Tree are 0.95, 0.62, and 0.68, respectively. From the results obtained, the performance of the classification model needs to be improved because the classification model tends to predict positive sentiment class. wisatawan ini dapat mempengaruhi dan memberikan pertimbangan bagi para calon wisatawan lain yang akan mengunjungi obyek wisata tersebut. Salah satu platform wisata yang populer adalah TripAdvisor. Ulasan pada platform ini mengenai obyek wisata Gunung Bromo dianalisis lebih jauh sehingga pihak pengelola obyek wisata dapat mendapatkan informasi yang dapat digunakan sebagai dasar pengembangan obyek wisata yang dikelolanya. Analisis sentimen dengan pendekatan klasifikasi dengan algoritma supervised learning dapat digunakan sebagai salah satu metode untuk menggali sentimen wisatawan yaitu positif atau negatif. Dari tiga algoritma pengklasifikasi yang diuji pada penelitian ini, tingkat akurasi tertinggi model klasifikasi dihasilkan oleh algoritma Decision Tree sebesar 91% dan diikuti oleh Naïve Bayes dan Logistic Regression yang masing-masingnya 88%. Tingkat precision, dan f1-measure untuk Decision Tree masing-masingnya sebesar 0,95 , 0,62 , dan 0,68.

Through this system, the student admission process has not been effective and efficient because it requires a lot of time and money. In addition, with the manual admission system at MI Bani Hasyim, the target number of new students that have been set has not been achieved. From these problems, this study aims to create a web-based new student registration information system. The new PSB system has the ability to fill out registration forms, upload supporting data such as photos of new students, birth certificate, and family card, then the admin can validate the data and files of prospective participants to assess whether the registrant has met the registration requirements or not, and print out the form for re-registration. System development follows the waterfall method. The author uses PHP and MySQL.

Pests and diseases are considered as two of the main reason for these factors. Most coffee farmers in Indonesia, particularly in Province of Lampung are undereducated farmers. They still use traditional practices to identify pests and diseases. Using an expert system, we hope that farmers can accurately diagnose coffee pests and diseases. The main goal of this research is to develop a web-based expert system to diagnose coffee pests and diseases. To identify the pests and diseases Breadth First Search (BFS) technique was implemented. The data consist of 5 pests, 5 diseases, 28 symptoms of pest, and diseases the coffee plant. Certainty factor is used to weight the symptoms and it was determined by experts and the user. Then the certainty factor is iteratively computed the system to measure the likelihood of the diagnosis. To evaluate this system, 30 users were chosen and grouped into three clusters (the coffee experts, farmers, and agriculture students, computer science students).
