Abstract

The wide variety of products offered by a company, combined with the consistent demands of specific products from customers, create a certain problem for the organization when they want to market a new product. Organization need information that could help them promote the most suitable product based on their customer’s characteristics. The organization also need to suggest alternative products for customer if the requested product is unavailable. In this research, we design a Recommender System that could suggest either new or alternatif products to customer based on their characteristic and transaction history. This proposed system adopts Cosine Similarity method to calculate product similarity score and Content-based Filtering to calculate customer recommendation score and used as a model for the proposed system. Subsequently, these models are used to classify customers as well as products according to their transaction behavior and consequently recommends new products more likely to be purchased by them. Based on the testing results of the proposed system, it can be concluded that the chosen methods can be utilized to recommend products and costumer of products. It is shown that Precision and Recall of product similarity scores and customer recommendation for product scores are 100% and 93.47%.

Abstract

Immunization is one effort to improve the health (promotion) and disease prevention (preventive) thoroughly and continuously. Immunization has become mandatory in Indonesia, especially for children under the age of 12 years. Currently there are health centers that do not have a historical immunization record of each baby so the records of immunizing all babies are merged into one book. Currently the processing of delivers information held by health care facilities is still using the immunization schedule card provided during registration immunization program. Accordingly communication between health care facilities with parents of babies is not efficient. Therefore the aim of this research is to produce the design of immunization information system that helps the health care facilities to provide information and data about immunization schedule each of baby. On systems that have been designed, the health center can obtain data and information of the babies that follows immunization program quickly, providing an accurate historical data record of immunization and information about immunization schedule would do next. By using SMS Gateway technology that could remind and warned parents about schedules and types of immunization to be received next through these technologies.
