Abstract

Effectiveness is a condition that shows the level of success or achievement of goals measured by quality, quantity, and time in accordance with what has been planned before. The temperature sensor measures the amount of hot / cold energy produced by the object so that it is possible to know or detect the symptoms of temperature changes in the form of analog or digital outputs. A humidity sensor is a measuring instrument to assist in the process of measuring or defining the humidity of water vapor contained in the air. This study used three categories of low price, standard, and expensive. The sensors used are temperature and humidity sensors, namely DHT11, DHT21, and DHT22 which are tested at three different times namely morning, afternoon, and night outdoors, as well as in extreme hot temperature conditions using irons and extreme cold temperature conditions using ice cubes inserted into containers.  This study used a thermohygrometer as a comparison to determine the accuracy of the sensor. After taking data at three different times, namely morning, afternoon, and night outdoors and in extreme hot temperature conditions using irons and extreme cold conditions using ice cubes 30 times, the results obtained were DHT22 sensors with expensive categories whose effectiveness was better than DHT11 sensors and DHT21 sensors. Data from DHT11 morning difference in average temperature (T) = 0.70°C and humidity (H) = 20%, day 1.2°C and 10%, and night 0.70°C and 22%, as well as extreme heat 2.50°C and 4% and extreme cold temperatures average 0.50°C and 15%. The DHT21 sensor in the morning showed an average difference of 0.20°C and 12%, afternoon differences of 0.80°C and 15%, and night 0.30°C and 10%, as well as extreme heat of 0.90°C and 12% and extreme cold of 4.30°C and 4%. DHT22 sensor in morning difference of 0.10°C and 9%, afternoon 0.60°C and 15%, and night 0.10°C and 13%, as well as extreme heat 0.30°C and 12% and extreme cold temperature of 4°C and 2.50% compared to thermohygrometer.

Abstract

Public services generally only provide suggestion box to people who have complaints. In the ongoing complaints, namely the people use written media (suggestion and complaint boxes) and oral media (face to face with employees). The complaint handling system is not stored in the database which causes the unknown number of complaints that have or have not handled so that the handling of complaints is delayed or skipped. Every complaint that is recorded manually will attack the search for data and is not efficient because complaints must be met directly and do not rule out data being damaged or lost because there is no backup. This study aims to develop a Community Complaint Application in the Pitumpanua District and to find out the results of testing the Community Complaint Application in the Pitumpanua District. This study uses a model waterfall development with data collection techniques using techniques interviews, and questionnaires to measure the feasibility of the device software that has been developed with several Respondentts. System testing in this study uses several standards the quality of software development, namely ISO 25010, among others are functional suitability with good category results, very good usability, portability with good category results, Based on the results research is produced a Complaint Application Development Website-Based Society that can be used to make public complaints and manage the administration of public complaint reports.
