Global economic development has led to the high complexity of society's needs. Financial institutions are here to provide facilities to meet the increasingly complex needs of society. However, the existence of problem loans can be a serious threat so classification techniques in data mining are used to overcome this problem. This research develops a model that can predict customers' ability to make credit payments so that financial institutions can avoid problematic credit. In this research, the SMOTE resampling technique is used to see the effect of sampling in dealing with class imbalance and conducting credit assessments. The research results show that the model built using SMOTE has better AUC than the model without SMOTE. From the two machine learning algorithms, logistic regression and random forest, the results show that the random forest model with SMOTE has the best performance with an accuracy value of 90%, precision of 92%, recall of 88%, F1-score of 90%, and AUC value of 0.97. Based on the best model, ten important features were obtained that influence the process of assessing credit repayment capabilities, namely the normalized score from external data sources, the period for changing customer numbers, the number of previous installment payments, the customer's age, registration time, the period for applying for credit at the credit bureau, the period for changing identity documents, the time for updating information at the credit bureau, and the length of time the customer has worked. In addition, this research produces visualizations via dashboards that can be used to improve the process of assessing credit repayment capabilities. Keywords: Prediction; Logistic Regression; Random Forest; Credit; Repayment Capabilities.

Rukti Endah Village is a village that is part of the administrative area of Seputih Raman sub-district, Central Lampung Regency. Rukti Endah Village has enormous livestock potential with a village area of 800 hectares where the majority of people are livestock breeders and farmers. One of the livestock MSMEs in Rukti Endah Village is CV Raman Farm Sejahtera, known as Raman Farm. Raman Farm facilitates livestock groups in the area to develop livestock care businesses called Hotel Ternak. The Hotel Ternak accepts care for livestock by customers to be raised until they are ready to be sold, one of which is goats. The more customers and livestock they entrust, the more difficult it is to manage the development history of each livestock. Apart from that, to expand the business network, customer trust is needed through more professional business management by utilizing information system technology. This activity aims to create an information system for monitoring goat enlargement including the health history of goats which is named the Goat Enlargement Monitoring Information System (SI MBEK) using the Rapid Application Development (RAD) system development method by means of iterative development, providing assistance and management training and use of goat farming information systems and carry out activity evaluations. The method for implementing community service used is Participatory Rural Appraisal (PRA) in which partners actively participate in this activity. The result of this community activity was the construction of SI MBEK. The application of SI MBEK can increase effectiveness in managing livestock hotels for rearing goats. Because it uses the RAD-iterative development model, SI MBEK can continue to be developed into the second version and beyond by adding features according to further needs.
