This situation is also faced in several u niversit ies that stores various kinds of data, especially new admissions database. But the abundant data has not been widely used in digging the information or knowledge that can help university management in making strategic plans. Every year there are new students who retire that do not register, therefore, it takes an application that can process a lot of data to find out the possib le retirement for new students. To find out the prediction retirement prospective students, this paper uses C.45 algorithm. The method can change the a very large fact into a decision tree that represents the rule. The result of this research is that the application can classify the new students in tree structure in order that it can produce a rule. This application is able to predict the possibility of the retirement of new student. With this application, it is expected that the possibility of a prospective student will retire from college can be known at an early stage, so the management can make a decision easily. Development of this application built uses PHP as the interface application system and MySql in database processing. System development methodology used is the waterfall model","PeriodicalId":32019,"journal":{"name":"JOIN Jurnal Online Informatika","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87002813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Greenhouse can be one solution to solve this problem, by utilize greenhouse our enviroment can be controlled and also protect the plants from outside interference. During this condition is still done manually both to measure the temperature or watering the plants. In this study the author developed a system to monitor and automate room temperature and soil moisture in greenhouse by utilizing Wireless Sensor Network (WSN) technology. The system consists of 1 node temperature and humidity chamber and 1 node of greenhouse soil moisture where each node is composed of arduino uno as its microcontroller, ESP8266 as Wi-Fi module, sensor, and relay. The results of monitoring and automation data will be sent to the web server by wireless, to make it easier for greenhouse farmers and monitoring their greenhouse. The results of this study can be found that the system is able to monitor and perform automatic control of temperature decrease, when the temperature reaches more than 28C and able to increase soil moisture automatically when the soil moisture is less than 40%, in addition by using ESP8266 data monitoring and automation results can be sent to the web server but based on the test results obtained that the maximum range of data transmission is 50 meters from the node to the access point.","PeriodicalId":32019,"journal":{"name":"JOIN Jurnal Online Informatika","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74614547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
