Abstract

The problem and obstacle currently experienced by aquarium users is that users have to check the condition of the food and water conditions by coming directly to the aquarium. This method can be annoying and waste a lot of the user's time working and it is certainly not easy if every time the user has to directly check the condition of the feed and water in the aquarium. So from this problem I designed a system, namely designing an aquarium prototype based on IoT (internet of things) which can help with the problems being faced by aquarium users. This system is a sophisticated manual system using Arduino Wemos D1, Turbidity sensors and Proximity sensors to determine the condition of fish food and water conditions in the aquarium. With this system, it can make it easier for users to know the condition of the feed and water conditions in the aquarium, so that the user's time is not wasted and the user does not need to bother taking care of the condition of the aquarium. From the results of water testing using the Turbidity sensor, the values ​​for very turbid water conditions were 266, 272, 281, 283, turbid water 518, 526, 536, 544 and clear water 589, 590, 594, 595. In the Proximity sensor test, the has a value of 1 when the sensor detects the presence of food and the sensor has a value of 0 when it does not detect the presence of food.

Abstract

A parking area is a place where consumers or the public can park their cars or vehicles in the empty spaces provided in the parking lot. Usually the parking area is filled with quite a lot of vehicles, so it is difficult to find empty parking spaces that are still available in the parking area, due to the density of cars or vehicles passing around the parking area who also want to find empty spaces that are still available to park their cars. This thesis aims to create a parking system that can be monitored via smartphone to determine the availability of parking slots. The parking system uses a raspberry pi microcontroller, an infrared sensor which functions to detect cars entering each parking space, LEDs are used as indicator lights to notify the status of each parking space. The results obtained from system testing are that the system has been successfully implemented as expected based on respondents' responses to the feasibility of an IoT-based intelligent parking system application using questionnaire data from 40 respondents indicating "Strongly Disagree = 0%", "Disagree = 0.5%" , “Neutral = 20.5%”, “Agree = 93.5%”, “Strongly Agree = 88%”. The maximum distance for infrared sensor detection is 80 cm. Meanwhile, the speed of obtaining data values ​​from the sensor also depends on the distance and voltage applied to the sensor.

Abstract

This study aims to find out how the influence of product quality on consumer buying interest with customer satisfaction as an intervening variable on the market share of london public healthy care product. The research method used is the method of qualitative data and quantitative data. While the data used is primary data. The data analysis method in this study uses simple linear regression analysis to obtain a comprehensive picture of the influence of product quality variables on consumer buying interest using the SPSS 25 for Windows program. To find out whether there is a significant effect of the independent variable on the dependent variable, a simple linear regression model is used.
