Dengue Fever is one of the viral diseases of the tropics that are easily spread in high density and humid area such as in Surabaya. Many researchers in various expertise have studied this disease. Some of them use statistical and machine learning approach to predict the outbreak of the disease, so that the government can prevent that incident. In this paper we use the geographically weighted regression for predicting the dengue fever outbreak in Surabaya. The geographically weighted regression has superiority in estimating the coefficient of the explanatory variables locally. So that, we can put more attention into the region with has high estimates coefficient parameters. Here, we look at the locally estimates of the dengue fever infected in the year 2016, 2017, population density and poverty percentage for predicting the dengue fever outbreak in the year 2018. In this study, the pattern of the predicted model can follow the pattern of the true dataset.
Reliability Centered Maintenence (RCM) is a systematic maintenence strategy based on system reliability. Application of RCM process will not always come out with a binary output of "yes" and "no". Most of the time they are not supported with available detail information to calculate system reliability. The fuzzy logic method attempts to eliminate the uncertainty by providing "truth" in different degrees.Data and responses from maintenance department will be processed using the two methods (reliability centered maintenance and fuzzy logic) to design maintenance strategy for the company. The results of the fuzzy logic RCM application are maintenance strategy which fit with current and future condition.
Digital native held information in their hands through the gadget. Previous research to 460 respondents in six university libraries in Surabaya, Indonesia shows that overall quality of the library is excellent. However, it does not encourage them to come to the library. Therefore, library needs to facilitate digital native needs by repositioning as a community hub, a place where community interact, collaborate and learn. The library can also apply a hybrid library concept by adding digital collection through subscription or repository. Findings from previous research show that there are facilities need to be prioritized to encourage digital native to come: common rooms, discussion rooms, and books that support students’ academic needs. These facilities are re-arrange as a new library interior design. The method used to redesign the libraries are by conducting an interview with the users and questionnaires. It is found that each library visitors have different characteristic and preference, therefore the interior must be designed to accommodate those need.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
