Abstract

Clean water is a basic human need that is used for daily activities. However, as the population increases, the need for water also increases. One method of conserving water resources is Rainwater Storage. Conventional rainwater storage cannot be appropriately monitored, maintain water quality, and only works like a container, which, if left to continue, can result in the collected rainwater becoming a source of disease and dangerous for users. This research aims to create an automatic rainwater collection system and water quality monitoring that can control the flow of water that will enter the reservoir to keep the water entering the reservoir of good quality. In the manufacture of this system, three sensors are used, including a pH sensor, a water turbidity sensor, and a TDS (Total Dissolved Solids) sensor. In determining water quality, the k-Nearest Neighbor (k-NN) method is used to classify whether the water is feasible, less feasible, or not suitable for consumption. Data transmission uses the ESP8266 WiFi module, and monitoring data can be viewed on the website. Testing the system using an experimental method, and in testing, it is found that this system can classify water quality with an accuracy rate of 70%.

Abstract

Accidents caused by malfunctioning of the brake light system are increasing in line with the rise in road facilities. It provides space for drivers to drive vehicles quickly. To overcome this problem, a system that can signal the driver must rapidly identify the damaged brake lights. The purpose of this study was to produce a car brake indicator tool. This tool is an electronic device that functions to determine the brake light when one of the brake lights is off by automatically giving a signal on the car's dashboard. The method used to produce brake work indicator tools consists of designing, manufacturing, and testing. The testing process has been carried out through a lux meter, and the test variables include testing the use of electric current, voltage when the tool is working, and trying the performance of the device on the car. From testing this tool, the results obtained when the current usage of the tool is working, namely before the induction works of 2 amperes and when the induction works it is 0.5 amperes. The magnitude of the voltage when the device is used is 11.8 volts. Based on the experiments that have been carried out, there are no disturbances in the lighting system or other systems on the car when this tool is working. This tool can work well to provide convenience and comfort when driving by car.

Abstract

The Payment System is a series of interconnected components consisting of rules, institutions, and procedures used for money transactions in fulfilling the obligations of economic activities. The Duta Bangsa University of Surakarta is a case study in this research where the student payment system is still a billing system. The faculty finance department gives bills tuition fees to students one by one. Moreover, it determines the bank used for payments. It resulted in quite many queues when filling out the study plan card (KRS) and exams. This research aims to produce a web service application and standardization with good performance in the payment process at Duta Bangsa University through virtual accounts from various banks and payment channels. The method used to achieve the authors' goals in this study is the Rational Unified Process (RUP) method. The research result is a web service application that can make invoices, inquiries, payments, and reversals of various bank payment channels. The User Acceptance Test results show a very agreeable value of 94.17%, so that the web service is feasible for the production version application. While testing the response time to measure performance for 7 (seven) days, the average response time was 0.49809 seconds.

Abstract

This study aims to determine the effect of modification of the Honda Tiger 2000 on exhaust emissions of CO and HC. The method used is to modify the carburettor venturi piston and replace the rocker arm with a roller rocker arm. The exhaust emission test used a gas analyzer type SUKYOUNG SY-GA 401. The object of the study was a Honda Tiger 2000 motorcycle. The results showed that modification of the Honda Tiger 2000 motorcycle at idle, 1000 rpm, 1500 rpm, and 2000 rpm increased CO emissions but reduced HC emissions. Based on comparing the motorcycle emission threshold values for manufacture ≤ 2010, namely CO emissions exceeding 5.5% and HC emissions less than 2400 ppm. Pertamax Turbo fuel consumption is more efficient than Pertalite with a distance ratio of 45 km requiring 1L Pertamax Turbo and 1.4L Petalite.
