<![CDATA[Basic electricity tariffs are increasing and the number of uses of electrical equipment is one reason for every people to saving. One of the biggest contributors of electricity is lighting. Effective and efficient tools are needed to control the lights so that they can quickly and precisely turn on and off the lights. Light control using a microcontroller connected to the internet become solution in this study. Microcontroller on Wemos D1 Mini is used for the central system, while the social media telegram is the control application. Wemos D1 Mini is connected to the relay module to turn lights on and off. Wemos D1 Mini is connected to the internet via wifi so telegrams can communicate with it. A telegram account is made specifically as a bot to take orders from users who control electricity. The bot account is implanted on Wemos D1 Mini. The user's private telegram account is used to communicate with bot accounts. Users can turn on, turn off and view the lights conditions by giving commands to the bot account. The tools was testing to internet connection, in seven different locations and far away from it. Each location was conducted twelve experiments. From these experiments, the test results show the device works properly because there are no feature errors. The command to turn off, turn on and display the status of the lamp can be replied to properly. Need a good internet connection to get maximum results.]]>

<![CDATA[Bandar Lampung City is the centre of the economy, services and trade in Lampung Province so that a healthy city environment needs to be kept clean and comfortable to support people's lives in carrying out daily activities. One factor that affects the cleanliness and comfort of the city of Bandar Lampung is the condition of air quality in the city of Bandar Lampung. The number of vehicles and industrial factories in the city of Bandar Lampung has become a major factor affecting air quality, such as the increase in harmful pollutant gases such as carbon monoxide gas (CO) and carbon dioxide (CO2), dust (PM10), nitrogen dioxide gas (NO2) and sulfur dioxide gas (SO2).Pollutant gas monitoring is one of the solutions in creating good air quality for the community. One of them is by utilizing information and communication technology. One of the utiliparameterion of information and communication technology in air quality monitoring is to use Wireless Sensor Network (WSN). WSN technology, which is the technology used to distribute and acquire data that is monitored and controlled centrally. This research builds an air pollution monitoring system in Bandar Lamping City by utilizing WSN and GSM technology for wireless data transmission to server applications. The results of this study are air pollution monitoring systems running well by displaying the outputs of sensor node acquisition based on the parameters of carbon monoxide (CO), dust (PM10), nitrogen dioxide (NO2) and sulfur dioxide (SO2) gases. The results of the calculation of the average overall sensor nodes for each parameter are 49 μg / m3 for PM10 substances, 34 μg / m3 for SO2 substances, 24 μg / m3 for NO2 substances, and 25 μg / m3 for CO substances. Based on the ISPU index and category, the results are in a good category. This means that the condition of air quality in the city of Bandar Lampung in the good category.]]>

<![CDATA[Dengue fever is a one of the dangerous diseases and very often causes casualties every year, especially in the tropics or subtropics countries. Dengue fever cases increase during the rainy season, many factors affect the spread of dengue fever, such as vegetation, population and landfills. The aim of this research is to predict the number of cases of Dengue fever using support vector machine. The data used are dengue data in Bandar Lampung City, weather data, population data and distance matrix data between dengue fever events with each other. The amount of data used is 1,080 data with 3 kernels: linear, gaussian and polynomial. In this study four experiments were carried out, the first two experiments were carried out without Feature Selection and the next two experiments were carried out with Feature Selection. After the experiment was found The best performance in the experiment with Feature Selection with 44 Variables. From the experiments conducted, Gaussian kernel achieved the highest R2 value which is 75.52%, while the Linear kernel and Polynomial Kernel achieved R2 value of 74.61% and 75.15%, respectively]]>

<![CDATA[Clean water has a very important role in human life. If an area is difficult to get clean water for daily needs, then they have to buy water to get it. Based on these problems, research was carried out in the form of a filter tool that can be used to filter turbid water into clean water so that it can be used for daily needs and can be monitored in real-time. To be able to make these tools requires software to program so that all hardware can run, the components used are electronic components consisting of an Arduino Mega 2560, HC-SR04 Sensor, Turbidity Sensor, SIM 800L, Waterpump, and a simple water filter as a compliment. This tool works automatically, when the water tank is full of clean water, the user will receive a notification in the form of an SMS. It is hoped that the existence of this tool can help to get clean and healthy water for daily needs.]]>

<![CDATA[High business competition forces businesses to adapt to the needs of increasingly complex information systems. One of the market demands is the ease of conducting transactions that are mobile but still integrated with the company's overall information system. This challenge is also faced by a small business Kafa Photography engaged in the field of photography services for public. This business requires a data access system that is secure and supports multiple interfaces. Utilizing REST web service technology that can be used as a communication bridge between different access technologies can help the intended system integration. To improve the security of business process related information, it is necessary to add a cryptographic data mechanism. This research will develop a middleware utilizing the viginere cipher cryptographic method on REST-based web service services for the Kafa Photography business venture. The results of research in the form of web service architecture which are used as connectors between different applications, namely web and mobile that support business processes. To test the functionality and compatibility of the outcome, researcher use the Postman application tool and the prototype of mobile and web applications. The effectiveness and efficiency of derivative applications that use web services to improve services for Kafa Photography customers are not measured in this study.]]>

<![CDATA[The initial purpose of saving and loan cooperative is giving a financial solution for the members only. As time goes by, nowadays cooperative can provide finance support for small enterprise and public society. Transactions which always increasing can cause trouble in data management. The price of the application that is relatively expensive can be a problem for cooperative which don’t have any information system yet. Furthermore, user needs IT expert for maintaining and updating system. Saving and loan information system using SaaS model (Software as a Service) can be a solution to the problem. With the SaaS model users do not need to buy the app, just by subscribing with the application directly to use the application. Saving and loan multi cooperative information system developed for ease the saving and loan data management. Saving and loan multi cooperative information system developed with Extreme Programming method by using PHP languages, and Laravel Framework. The conclusion of this research is saving and loan multi cooperative information system is successfully built according to user needs, by displaying data transparently.]]>
