Abstract

Floods, fires and gas leaks that occur often cause problems that can result in losses that are not small in value. The absence of an early warning system when floods, fires and gas leaks make people less alert. In this study designed a flood detection system, fire detection and leak detection in gases that work automatically based on a microcontroller. The water level monitoring system is carried out by using an HC-SR04 type ultrasonic sensor that will read the water level, the fire monitoring system is carried out by using a DHT11 type temperature sensor that will detect the occurrence of fire while the gas leak monitoring system is carried out by using a gas sensor type MQ-9 will find out the gas leak. If all three sensors detect parameters such as rising water levels, rising temperatures and high gas concentrations, the system will sound the buzzer as an early warning sign. This system connected to the Internet of Things (IoT) which will display data in real time displayed using the web-based IoT Platform, Mapid. With this system, it is expected that the public can be more alert to floods, fires and gas leaks.

Abstract

Lack of green land in urban areas makes gardening difficult. The high mobility of city residents makes gardening on urban agricultural crops. However, these problems can be overcome by gardening with a controlled urban farming system. In this research a monitoring system is designed that can read soil moisture in the urban farming system. The humidity monitoring system is carried out by implementing the YL-69 sensor which will determine the level of soil moisture. This Soil Moisture Monitoring System will be connected to the Internet of Things (IoT) which will display data in real time. The output of the YL-69 type humidity sensor in real time is required using the Web-based IoT Platform, Thingspeak. With this system, it is expected that the community can be more efficient and productive in conducting gardening activities in urban areas

Abstract

Some administrative procedures in many institutes are still carried out conventionally, which is deemed less efficient and takes much time. On the other hand, communication with other parties requires a process of exchanging information, so a system is needed to confirm the validity of the information. Therefore, a digital letter system that can prove the validity of the information gained through the digital media right from the party concerned is developing. This can be overcome using the authentication method. Adding One Time Password (OTP) as an authentication method that employs one temporary password key can be the solution. This study uses the One Time Password (OTP) method as a validation system and the SHA-512 algorithm as an OTP code generator to generate random codes. This system leverages android technology on mobile to ease access to the correspondence administration system to make it easier to visit with features that prioritize information and access speed. This application is implemented at the State Polytechnic of Sriwijaya to improve the administrative process to run more effectively. The black box testing revealed that all available menus and features were appropriate, and the application already had a system that functions according to user needs. Moreover, in the One Time Password generation test with the SHA-512 algorithm, it was determined that the average response time for generating the OTP code was 4.4 seconds in 15 trials, which can be considered fairly accurate.

Abstract

State Polytechnic of Sriwijaya currently uses the conventional method of distributing information, such as posting event pamphlets on campus bulletin boards. However, this method has proven ineffective because many students rarely see the bulletin boards, resulting in some failing to register for events because they are unaware of them. In addition, the procedure for registering event participants is still inefficient, as participants' information is handwritten on the registration form paper, which might result in the paper being lost or damaged. Then, the event certificate issuing system still in physical form will necessitate a lengthier issue procedure. Therefore, an event management system must be created to facilitate the distribution of information about upcoming events at the State Polytechnic of Sriwijaya. This system also incorporates ticket purchasing and certificate issuance using Android and the Laravel website, allowing for more efficient event ticket purchase and issuing electronic certificates (e-certificates). The prototype method is used in the application development method and the Unified Modeling Language (UML) system was used in the system design phase, while MySQL was employed as the database. This study reveals that the designed application system can efficiently support the online distribution of information, ticket purchasing, and issuance of electronic certificates. The findings of system testing via the blackbox method demonstrate that all of the designed application system's features operate correctly and effectively. From the results of the UAT test, this system is included in the very feasible category. Supported by the results of software testing of each factor: variable functionality 96.2% (very feasible), variable Efficiency 97.2% (very feasible), variable Usability 96.2% (very feasible).
