Khaerun Nisa, Adi Chandra, Nurwahid Syam — Tue, 10 Feb 2026 00:00:00 +0800

This study aims to design the Development of a Pond Water Quality Monitoring System Using the Esp32 Microcontroller in the Panyutanah hamlet shrimp pond, to implement and determine the community's response to the development of the Pond water quality monitoring system using the Esp32 microcontroller with Telegram notifications.

This research uses development research methods adapted from the 4-D model (Four-D Model), which includes the stages of defining, designing, and developing.

Based on the results of research on developing a pond water quality monitoring system using the Esp32 microcontroller, it can be concluded that: (1) This tool uses the Esp32 Microcontroller as a data processor, servo motor (water pump) as a place for water to enter and exit, the LCD functions to display the pH value and the temperature given by the sensor, as well as Telegram as a monitoring tool. As for testing the system used using the Black Box method. (2) From the test results it was found that the development of a pond water quality monitoring system using the Esp32 microcontroller could make it easier for shrimp farmers to know the water quality automatically.

PROTOTYPE OF A LAYER CHICKEN EGG COUNTER IN CHICKEN COOPS USING ESP8266 AND ULTRASONIC SENSOR BASED ON IOT

Hasnita sari, Dedy Hendryadi, Juniarti Iryani — Sat, 04 Oct 2025 00:00:00 +0800

This study aims to (1) Make an automatic egg counter prototype, (2) Know how the automatic egg counter prototype works, (3) Know the response of laying hen cage owners. This study uses the prototype research method. Prototype research has several stage of research, namely needs analysis, rapid design, build prototype, evaluate initial users, improve prototype, implement and maintain. The results of the study showed that: (1) The prototype of a purebred chicken egg counter in a chicken coop used an esp 8266 and an iot-based ultrasonic sensor was made based on ac curate research results and thoughts and valid data by carrying out various stages of existing research and this prototype was tested on farms owned by Mrs. Darmiati who is in jonjoro, panggaloang village (2) The user’s perception says that this prototype is good, and in accordance with the previously designed system and one day it can be applied directly to the chicken coop so that it can help with egg counting work (3) Based on the data obtained from the results prototype trials on two respondents obtained good results very positive with a percentage value of 81,1% and the results of these calculations will appear in the blynk application.

WEB-BASED BATIK CLOTHING SALES INFORMATION SYSTEM AT DANISWARA BOUTIQUE BULUKUMBA

Nurlaelah Nurlaelah, Dedy Hendryadi, Nurwahid Syam — Sat, 04 Oct 2025 00:00:00 +0800

This study aims to: (1) design a web-based information system for selling batik clothes at Daniswara Boutique Bulukumba. (2) implementing a web-based sales information system at the Bulukumba Daniswara Boutique. This research uses the waterfall method is a software development method with a linear sequential model, starting from the system requirements analysis, design, coding to the testing stage. This method has stages, namely: (1) Requirements analyst, (2) Design, (3) Implementation (Build & Coding), (4) Integration and Testing (Integration & testing), (5) Operation and Maintenance (Operation & maintenance). Based on the results of research on the web-based information system for selling batik clothes, it can be concluded that: (1) The web-based batik clothing sales system was built using Sublime software (text editor), MySQL Xampp 7 Database Management System (DBMS) uses the waterfall method and with the PHP programming language. (2) The batik shirt sales system consists of 2 users, namely Admin and Buyer. Based on the test, it was found that the web-based batik clothing sales information system can be used to facilitate data entry of goods, and make it easier for buyers to see the available categories of goods and can meet the needs of the user to select the desired item category.

PROTOTYPE OF A HOUSE FIRE DETECTION AND EXTINGUISHING SYSTEM USING A WATER PUMP BASED ON ARDUINO UNO

fikra nur rahma, Raden Wirawan, Muh Awal Nur — Sat, 04 Oct 2025 00:00:00 +0800

- This research aims to: (1) Designing a home fire detection and extinguishing device using an arduino uno-based water pump. (2) Knowing how sensors and microcontrollers work in the prototype of detecting and extinguishing house fires using an arduino uno-based water pump. The method used in this research is prototyping. The stages in the prototype method are collecting requirements, building prototypes, evaluating prototypes, coding systems, testing systems, evaluating systems, using systems. The results of the research show that: (1) The prototype of a home fire detection and extinguishing system using an arduino uno based water pump is designed using a system block diagram consisting of inputs, processes, output where inputs are flame sensors and MQ-2 sensors, processes, are arduino, relay and sim 800l gsm modules and outputs are buzzers, water pumps and call to cellphones. (2) This prototype was made using two sensors, namely the flame sensor and the MQ-2 sensor as inputs that can work properly where the flame sensor functions as a fire detector and the MQ-2 sensor as a smoke detector in every room. Each sensor produces an output in the form of a digital value or number, namely 1 and 0. This value is used as a condition on the Arduino Uno to produce output in the form of a buzzer, water pump and call.
