Abstract

The health and comfort of infants are highly sensitive to room environmental factors, particularly temperature and humidity, which play a critical role in supporting their well-being. Managing these factors becomes complex due to constant fluctuations in ambient conditions, necessitating the use of advanced technology to ensure stability and adaptability. This study explores the application of fuzzy logic in designing a temperature and humidity control system for infant rooms, aiming to maintain an optimal environment for infant care. Fuzzy logic offers a robust approach for handling variability, enabling precise adjustments based on a set of predefined rules and inputs. The system operates by processing real-time input values of temperature and humidity and producing adaptive responses through control outputs, such as cooler, heater, and blower settings. These adjustments are determined by a series of if-then rules that interpret the input conditions to produce the necessary responses. Experimental testing and evaluation confirm that the fuzzy logic-based control system effectively maintains room temperature and humidity within the desired range. The results indicate that this approach can successfully sustain a stable and comfortable environment, underscoring its potential application in enhancing infant health and comfort through controlled indoor climate conditions.

Abstract

Strawberry is a kind of plant that can grow well in the highlands. The cultivation of strawberry plants requires a large area of ​​land, whereas in urban areas the land is increasingly narrow. The best solution to overcome this is by cultivating an aeroponic system. Aeroponic systems utilize the element of water or solution which is sprayed in the form of mist and will hit the roots of plants. The pH monitoring system in strawberry plants is carried out to observe changes in the PH of the water sprayed to the roots of the plants according to the PH requirements of the strawberry plants. The monitoring system using Android with a user interface that is easy to use and PH information of strawberry plants can be easily monitored. At pH, it has an error of 0.33%, while for other tests it has an error of 0.16%. For sending data with the HC05 module testing with a distance of 10 meters and 20 meters the device can be connected properly and data reception is also good. For a distance of 25 meters and 30 meters, there is a delay in the process of receiving data, for testing distances of 35 meters and 40 meters the receipt of data is incomplete and the data displayed is also irregular. Then for testing with a distance of 55 meters an error occurred and a distance of 57 meters could not be connected

Abstract

Budidaya maggot (larva) Black Soldier Fly (BSF) memiliki peran penting dalam pengelolaan limbah organik dan produksi pakan berprotein tinggi. Namun, proses pengendalian suhu dan kelembapan dalam kandang masih dilakukan secara manual, menyebabkan kondisi lingkungan yang kurang stabil dan berpotensi menghambat pertumbuhan larva. Suhu optimal untuk mendukung pertumbuhan maggot berada pada kisaran 24–30°C. Penelitian ini mengembangkan sistem otomatis berbasis mikrokontroler ESP32 yang dilengkapi sensor suhu DS18B20 dan sensor kelembapan soil moisture sebagai input utama. Sistem ini menerapkan logika fuzzy Mamdani untuk mengendalikan tiga actuator utama, yaitu heater, exhaust fan, dan mist maker secara otomatis dan mandiri. Sebanyak 9 aturan fuzzy digunakan untuk merespons kondisi kandang secara real time dan menghasilkan durasi kerja actuator yang adaptif serta tepat sasaran. Hasil pengujian menunjukkan sensor suhu memiliki tingkat akurasi tinggi dengan error antara 0.01%–0.07%. Dengan pengaturan otomatis ini, kondisi kandang dapat dijaga tetap stabil, mendukung pertumbuhan maggot yang optimal, efisien, konsisten, dan berkelanjutan.
