Abstract

The development of Internet of Things (IoT) technology has had a significant impact in various fields, including the fisheries sector. In fish farming, water quality and feeding efficiency are important factors that affect fish health and growth. This study aims to design and implement IoT-based automatic fish feed and water turbidity monitoring system. This system uses an ESP32 microcontroller connected to a turbidity sensor to monitor water turbidity levels, an ultrasonic sensor to detect feed levels, and actuator devices in the form of servos and water pumps. Turbidity data and device status are transmitted in real-time via MQTT protocol to web-based monitoring application and an Android app. Test results indicate that the system can accurately monitor water turbidity levels and activate feeding according to a schedule or manually via the user interface. The testing was conducted in a 40x12x15 cm aquarium containing five guppy ornamental fish, and on the seventh day, an increase of 1 NTU was recorded. The implementation of this technology is expected to improve operational efficiency, reduce feed waste, and maintain aquarium environmental quality sustainably..

Abstract

Hepatitis is a liver disease characterized by inflammation. Inflammation is indicated by elevated liver enzyme levels, which are caused by disruption or damage to the liver membrane. Given the significant negative impact of this disease, serious prevention and treatment of the dangers of hepatitis are necessary. Efforts to minimize these risks can be achieved by increasing public awareness of the factors that can cause hepatitis. Therefore, a system is needed that can serve as an alternative to consulting a doctor for the general public. The purpose of this research is to develop an expert system that can serve as an initial solution in the treatment of hepatitis. In its implementation, this expert system uses the forward chaining method. In this method, data is used to determine which rules will be executed to achieve a result. Based on the testing conducted, it can be concluded that this expert system application can be used by users for the early diagnosis of hepatitis

Abstract

Information and Communication Technology (ICT) has become a vital need in the world of education. SMAN 1 Ulu Musi faces the problem of suboptimal network infrastructure, particularly related to internet access and bandwidth management. The existing network is only a limited LAN without an internet connection. This study aims to design and implement a MikroTik-based computer network at SMAN 1 Ulu Musi to improve the quality of network services, perform fair bandwidth management, and support learning activities that utilize information technology. The method used is the Network Development Life Cycle (NDLC) which includes the stages of analysis, design, prototype simulation, implementation, monitoring, and management. The system implementation uses a MikroTik RB941 router connected to a 4G modem as the internet source. The implementation of the Mikrotik-based network succeeded in improving the stability and efficiency of internet access at SMAN 1 Ulu Musi. Before the implementation of the simple queue bandwidth, each client obtained 60 MBPS; after the simple queue was implemented to distribute bandwidth evenly, each client received a maximum allocation of 4 MBPS. QoS testing results showed good network performance: throughput of 0.6 KBPS, average delay of 0.866 seconds, jitter of 0.25 seconds, and packet loss of 0%. All client devices could connect and access the internet stably without significant disruptions. The implementation of a MikroTik-based computer network proved effective in improving the quality of network services at SMAN 1 Ulu Musi. This system succeeded in creating a network that is stable, manageable, and supports equitable internet access for learning activities.

Abstract

The implementation of examinations is one of the important activities in the learning evaluation process to measure the level of understanding and the achievement of students' competencies. In practice, problems are often encountered in the form of possible cheating due to similarities in the sequence of questions received by exam participants. Therefore, a method is needed that can effectively produce question randomization to improve the fairness and objectivity of the examination process. This study aims to implement the Multiplicative Congruential Random Number Generator (MCRNG) method in the examination system at SMPN 13 Kota Bengkulu as a mechanism for automatically randomizing the sequence of questions. The MCRNG method is used to generate pseudo-random numbers, which are then utilized in the process of randomizing exam questions. The study was conducted through the stages of system requirements analysis, randomization algorithm design, implementation of the MCRNG method in the examination system, and testing the results of the randomization that produced. Testing was conducted to determine the method's ability to generate variations in the sequence of questions that are different for each exam participant. The research results show that the MCRNG method is able to produce question randomization quickly and effectively with a good level of question sequence variation. The implementation of this method can reduce the likelihood of participants receiving the same arrangement of questions, thereby helping to minimize the potential for cheating during the exam. In addition, the system that was built is able to support a more structured, efficient, and transparent exam process. Thus, the application of the Congruential Random Number Generator (CRNG) method in the implementation of exams at SMPN 13 Kota Bengkulu can be an effective solution in improving the security, fairness, and quality of computer-based learning evaluation processes.

Abstract

Technological developments and the intensity of community activities have driven an increase in demand for electrical energy, thereby necessitating the exploration of sustainable alternative energy sources. One relevant solution is the utilization of Solar Power Plants (SPPs). This research focuses on the design and development of an energy consumption monitoring system for PLTS by adopting the Internet of Things (IoT) concept. The system development integrates PZEM-004T sensors to measure AC voltage, current, power, and energy parameters, ACS712 sensors for accurate current measurement, and special voltage sensors to monitor DC battery conditions. The entire control and data acquisition process is managed by the NodeMCU ESP32 module as the main processing unit. The data obtained is then displayed in real-time through the Blynk application interface. The research method applied is experimental, covering the stages of hardware design, software development, and overall IoT system integration. The evaluation results show that the system operates well, is capable of providing accurate electrical parameter readings, displays data with very low latency (around 0.1 seconds), and effectively supports remote ON/OFF control of electrical loads. Thus, this system is expected to contribute to improving

Abstract

This study aims to design and build an Internet of Things (IoT)-based temperature control device for broiler chicken cages. The system was developed to help farmers monitor temperature and humidity in real time and control a heating device remotely through a smartphone. The hardware consists of an ESP8266 microcontroller, DHT11/DHT22 temperature and humidity sensor, relay module, 40-watt incandescent lamp as the heater, LCD 16x2 display, power supply, and supporting electronic components. The software was developed using Arduino IDE and integrated with the Blynk IoT platform for monitoring and manual control. The research method used was experimental design with black-box testing on sensor detection, data transmission, relay response, and Blynk application performance. The test results show that sensor data were received within 1.8-2.1 seconds, while commands from Blynk were received within 2.5-2.7 seconds. The relay response to the heater ranged from 1.5 to 1.9 seconds, and the Blynk display response ranged from 2.3 to 2.9 seconds. These results indicate that the proposed system works properly for real-time temperature monitoring and automatic/manual heating control in a small-scale broiler cage simulation.
