To improve public services, accuracy and acceleration are needed in classifying the types of complaints so that complaints can immediately get a response from the relevant regional apparatus. This public complaint data is in text form and is not balanced in each category of regional apparatus, so we contribute to research to compare the performance of different text mining-based classification algorithms. In addition, we also tested the resampling method to overcome imbalanced data. In the final stage, testing is carried out using a multiclass confusion matrix table to show accuracy, precision, recall, and f1-score. The test results show the highest value in the Naïve Bayes algorithm with the ComplementNB model without resampling data, which is 89.58% accuracy, 86.72% precision, 82.40% recall, 84.09% f1-score. However, all scores decreased when combined with SMOTE resampling of 83.66% accuracy, 67.79% precision, 80.35% recall, 71.68% f1-score. ComplementNB can be an alternative model in the classification of public complaints with imbalanced datasets

Sign language is a language that prioritizes body language and lip movements, not sound, in communicating. The deaf and speech impaired are the main group who use this language by combining the form of finger movement, orientation and movement of the hands, arms, and body, to express their thoughts. This application uses pictures and questions to find out the information they convey. So this application was designed so that it can help the general public to receive information from the deaf and speech impaired by using Black Box testing to test for functional errors contained in the application.

Poverty index is a term for measuring poverty, this is done by a government agency or commonly referred to as the Central Statistics Agency (BPS). The poverty index or poverty rate is the percentage of the population in a province who is below the poverty line, which is the minimum in obtaining an adequate standard of living. In the government's efforts to reduce the level of poverty in a province, the government often provides special assistance programs for people belonging to the poverty line. Based on the explanations that have been discussed, a conclusion can be drawn. This research can be done using the Data Mining technique to group the total Poverty Index by Province in Indonesia using the K-Medoids Algorithm, then by determining the Clusters randomly. The results of this study are expected to assist the government in providing assistance to the affected population below the poverty line.

Delays in the completion of pvd production can be caused by several factors. Including the actual experience in the production of the difficulty of each process and color type, even the difficulty of the product type can also be affected. In this study, the prediction of the delay in the completion of pvd production was carried out using the C4.5 decision tree and Multilayer Perceptron data mining method approach using Production Results data at PT. Surya Toto Indonesia, whose results are expected to provide information and input for the company in making production plans in the future. The data testing method was carried out with 5 (five) testing times with different amounts of data to determine the level of consistency of accuracy obtained. C4.5 gives the results of a decision tree where the root is the color type and as the leaf is the product category, type type and order period. The average value of accuracy generated in the C4.5 decision tree method is 87.15%. While the Multilayer Perceptron obtained an average accuracy of 87.98%, which is greater than the decision tree method with a difference of 0.83%.

Peran pasif terbukti menjadi metode yang tidak efisien dalam sebuah layanan informasi. Penggunaan teknologi di perguruan tinggi membantu untuk menghasilkan sebuah layanan informasi yang efektif, fleksibel dan akurat di mana aktivitas interaksi mahasiswa dan dosen menjadikannya aktor utama dalam menjalin hubungan yang baik pada proses perkuliahan. Namun, menerapkan lingkungan di mana mahasiswa aktif dalam menjalin interaksi yang baik dengan dosen membutuhkan banyak usaha mengingat jumlah variabel yang terlibat dalam tujuan ini. Untuk mengidentifikasi variabel-variabel tersebut, perlu dilakukan analisis terhadap data yang dihasilkan mahasiswa untuk mencari pola-pola yang memungkinkan untuk diklasifikasikan menurut kebutuhannya. Setelah kebutuhan ini diidentifikasi, dimungkinkan untuk membuat keputusan yang berkontribusi pada proses aktivitas interaksi mahasiswa; untuk ini, penggunaan kecerdasan buatan dipertimbangkan. Teknik-teknik ini meniru proses pemikiran manusia menggunakan struktur yang mengandung pengetahuan dan pengalaman ahli manusia.

Information regarding monitoring of operational expenditures of the Regional Public Service Agency at the Emergency Ambulance Service Unit of the DKI Jakarta Health Office. Because the finances issued or used must be accurately informed. In this case, monitoring the operational expenses of the Regional Public Service Agency at the Emergency Ambulance Service Unit of the DKI Jakarta Health Service still has many obstacles. Constraints faced are such as the technical executor. The activity of submitting an accountability letter still has a long stage, the Verifier is not there so that the process of checking the accountability letter stops, the input of reports is carried out one by one by the Spending Treasurer using Microsoft Excel. The process of monitoring the operational expenses of the Regional Public Service Agency at the Emergency Ambulance Service Unit of the DKI Jakarta Health Office takes a long time. And another obstacle is the occurrence of classifying the type of operational expenditure. In this data analysis method, using Balanced Scorecard (BSC) analysis, system design uses Visual Paradigm to create UML (Unified Modeling Language), PHP programming language, MySQL to create databases. The result of this research is that an information system for monitoring operational expenditures of the Regional Public Service Agency can create and submit a letter of accountability and verification letters are carried out computerized, the Expenditure Treasurer no longer enters the general cash books one by one, the Expenditure Treasurer no longer classifies the types of operational expenditure in recap operational expenditure.
