Abstract

The telecommunications sector is facing increasing competition, and customer churn is still a majorchallenge despite the implementation of advanced promotions and high-quality services. Churn refers tothe discontinuation of services by customers, influenced by several factors that can be found through datamodeling. This study compares two predictive models, Random Survival Forest (RSF) and Fuzzy RandomSurvival Forest (FRSF), for predicting customer churn time in the telecommunications industry. Bothmodels are evaluated using the median C-index value obtained from 20 repetitions, ensuring moreconsistent and reliable results. RSF, a widely used survival analysis method, has shown strong predictivepower, with studies reporting up to 99% accuracy in churn prediction. However, FRSF, a modified versionthat incorporates fuzzy logic, has proved superior performance, particularly in handling imprecise oruncertain data. The results show that FRSF achieves a lower error rate of 0.1739, compared to RSF's errorrate of 0.1906. These findings suggest that FRSF outperforms RSF in churn prediction, making it a morereliable and righter model for finding at-risk customers. The study concludes that the FRSF model is thepreferred choice for predicting churn in the telecommunications industry, offering better predictive qualityand consistency in handling uncertain data.

Abstract

Technological developments have encouraged various business sectors to adapt to digitalization, including the baby equipment rental sector. This study aims to design and build a web-based baby equipment rental information system using the Laravel Framework at the Rafana Rent Store in Palopo City. The method used is a qualitative descriptive approach using a prototype development model. Data was obtained through interviews, observations, and documentation of the rental process carried out manually. The results of this study indicate that the system created can overcome various problems in the manual rental process, such as delays in service, recording, which is still done manually in notebooks, and lack of efficiency in payment confirmation. This system provides main features such as online ordering, uploading proof of payment, and managing stock of goods. Through the trials, the system was considered to facilitate customers in carrying out the rental process, which can be done anytime and anywhere, and help shop owners manage transaction data more accurately and provide efficient service to customers. Implementing this system is expected to improve the quality of service and speed up and simplify the rental process. The Rafana Rent Store can manage its business more professionally and be ready to face the digitalization era.

Abstract

The Cox Proportional hazard model is a popular method to analyze right-censored survival data. This method is efficient to use if the proportional hazard assumption is fulfilled. This method does not provide an accurate conclusion if these assumptions are not fulfilled. The new innovative method with a non-parametric approach is now developing to predict the time until an event occurs based on machine learning techniques that can solve the limitation of CPH. The method is Random Survival Forest, which analyzes right-censored survival data without regard to any assumptions. This paper aims to compare the predictive quality of the two methods using the C-index value in predicting right-censored survival data on churn data of the telecommunication industry customers with 2P packages consisting of Internet and TV, which are taken from all customer databases in the Jabodetabek area. The results show that the median value of the C-index of the RSF model is 0.769, greater than the median C-index value of the CPH model of 0.689. So the prediction quality of the RSF model is better than the CPH model in predicting the churn of the telecommunications industry customer.
