Abstract

Since the inauguration of Regulation the Republic of Indonesia's Minister of Health No. 82 in 2013 concerning Hospital Management Information Systems obligates UNRI Hospital has a system that handles patient registration in the form of an information system. However, since its inauguration in 2013, UNRI hospital has used the Hospital Management Information System (SIMRS) which has been implemented since 2017. UNRI hospital still use conventional methods for patient registration and consultation. Prospective patients must fill in forms and submit equipment documents such as a photocopy of UNRI civitas identity card (for UNRI civitas) and Identity Card (KTP) and to register as a patient before consulting. This research uses Waterfall method in addition to being easily understood this method also has sequential stages so that there are no overlapping stages.. While the system design uses Context Diagrams, Data Flow Diagrams, and Use Case Diagrams. The database used is MySQL with notification feature from Firebase. There are two applications built, namely Website and Android. Website outputs are tested using the Black-Box and Android applications are tested using User Acceptance Likert Scale. Results of the Black-Box test are UNRI Hospital patient registration Websites with criteria such as display menu on the main page, print button on the patient registration page, add button on the notification page, etc. Results of User Acceptance testing on Android bassed on 33 questioner from 30 respondents has produced 87,12% Likert scale results.

Abstract

One of traditional foods of Indonesian people is tempe. Tempe is made from fermented soybeans with Rhizopus Oligosporus mold. In its production, producers’ tempe often fail. One of them is Harber Tempe Factory, located in Pelita Street, Pekanbaru City. Beside weather factors, there are no supporting tools for temperature and humidity detection at the factory, also become obstacles in fermentation process of tempe. Producers’ tempe do not know exactly how much temperature and humidity must be maintained for fermentation process. Manufacturers only can estimate temperature and humidity in fermentation room. If temperature is considered too hot, producers’ tempe will come to factory and open air pentilation. So, the room temperature is back to normal because house of producer’s tempe and tempe factory are separate.Tools used in this study are ESP8266 Module, DHT22, Relay, Power Bank as power, fan and battery. Internet of Things (IoT) is a concept where objects in physical form can be connected and can transfer data through internet network by sensors. The concept of IoT describes every object that can be connected to internet and can be controlled remotely without having to be in that place. With IoT, job will be made faster and easier. The results obtained from the test are if temperature and humidity are above or below of normal temperature (250C-320C), a notification will appear on user's smartphone via Blynk application. If temperature is too hot, fan will turn on automatically. If temperature is too cold, light will turn on. Monitoring data can be viewed on thingspeak in graphical form.
