The walet is a species of bird that provides many health benefits through its nest made of saliva, such as accelerating cellregeneration, strengthening the immune system, and aiding the digestive system. The high selling price of the bird's nest hasprompted many people to cultivate it. Temperature and humidity are important factors in walet cultivation, with the optimaltemperature ranging between 26-29°C and humidity between 80-95%. Bojonegoro district, East Java, is famous for its oil drillingactivity that increases temperature and lowers environmental humidity, making it unsuitable for walet cultivation. Therefore, there is a need for a monitoring system capable of maintaining the temperature and humidity of the walet house at ideal levels. This monitoring system works automatically without human intervention, saving time and effort. The objective of this research is to design and build a prototype temperature and humidity monitoring system based on the Internet of Things (IoT) for walet houses in Bojonegoro District. It is expected that the implementation of this system can significantly improve the quality and quantity of walet nests. Keywords: walet cultivation, temperature and humidity monitoring, Internet of Things (IoT), automatic system.

Due to their high nutritional content, oyster mushrooms are a valuable food source with increasing demand. However, increasing oyster mushroom production is challenging because they require specific environmental conditions and cannot grow just anywhere. Therefore, it's crucial to adjust the environmental conditions for optimal oyster mushroom cultivation. Base on the problem, there is a need for a system that can adjust environmental conditions to meet the optimal requirements for oyster mushroom cultivation. Oyster mushrooms typically thrive in highland environments. Several environmental parameters that can influence their growth include CO2 concentration (575-731 ppm), temperature (16˚C to 30˚C), and humidity (80-95%). The designed system is expected to measure these environmental parameters using sensors, include the MQ-135 sensor and the DHT22 sensor.Additionally, actuators will be used to control the environmental parameters and bring them to the desired levels, which is exhaust fan and DC pump. The use of these sensors and actuators will be integrated with an ESP32 microcontroller, which can proces and manage the system. To maximize the quality of the oyster mushrooms, the system will utilize the Internet of Things (IoT), for automated and remote monitoring and control of the oyster mushroom cultivation process through the Blynk application.

Ketersediaan dan kualitas air bersih sangat penting untuk kehidupan sehari-hari, namun pemantauan kondisi air dalam tangki masih sering dilakukan secara manual, yang dapat menyebabkan kesalahan serta potensi risiko kecelakaan. Penelitian ini mengembangkan sistem pemantauan volume dan kualitas air berbasis Internet of Things (IoT) guna meningkatkan efisiensi dan akurasi dalam pengawasan air. Sistem ini menggunakan sensor ultrasonik untuk mengukur ketinggian air lalu dikonversi menjadi volume, sensor pH untuk mengukur keasaman, sensor kekeruhan untuk mendeteksi kejernihan air, sensor TDS untuk mengukur zat padat terlarut dalam air, serta sensor suhu untuk mengukur suhu air. Data yang diperoleh dari sensor diproses menggunakan mikrokontroler ESP32 dan ditampilkan secara real-time melalui aplikasi Blynk, sehingga pengguna dapat memantau kondisi air dari jarak jauh. Hasil pengujian menunjukkan bahwa sistem ini mampu memberikan informasi akurat mengenai parameter kualitas air dengan tingkat keakuratan lebih dari 90%. Dengan adanya sistem ini, pemantauan kondisi volume dan kualitas air pada tangki air menjadi lebih efisien, efektif, serta menghindari risiko kecelakaan dalam pengecekan manual.Kata Kunci: Sistem monitoring air, IoT, sensor kualitas air, ESP32, Blynk

Pada era modern, speaker menjadi perangkat umum dalam berbagai kegiatan seperti presentasi, seminar, prosespembelajaran, hingga kegiatan luar ruangan. Namun, kebisingan lingkungan yang dinamis sering kali mengganggu kejelasan suarayang dihasilkan speaker. Penelitian ini merancang dan mengimplementasikan sistem pengatur volume speaker otomatis berdasarkantingkat kebisingan lingkungan sekitar. Sistem menggunakan mikrokontroler ESP32 sebagai pusat pemrosesan, MicrophonePreamplifier MAX9814 sebagai pendeteksi kebisingan, serta potensiometer digital X9C103S untuk mengatur volume speakersecaraotomatis. Data kebisingan diukur dalam satuan desibel (dB) dan ditampilkan pada LCD, serta dilengkapi MP3 player sebagaiperingatan jika kebisingan melewati ambang batas. Selain itu, terdapat relay sebagai saklar elektrik untuk mengatur nyala matinyadua komponen yaitu MAX9814 dan microphone. Hasil pengujian menunjukkan sistem mampu menyesuaikan volume speakersecararesponsif dan efektif terhadap perubahan kebisingan lingkungan, sehingga meningkatkan kualitas penyampaian suara dankenyamanan pendengar. Sistem ini diharapkan dapat diterapkan pada berbagai situasi seperti ruang kelas, atau tempat publik lainnyayang memerlukan pengaturan volume otomatis.Kata Kunci: Volume speaker otomatis, Kebisingan lingkungan, Potensiometer Digital

Permintaan energi listrik yang terusmeningkat mendorong pengembangan sumberenergi yang efisien, murah, dan ramah lingkungan.Penelitian ini mengkaji pengaruh molaritas larutanNaOH terhadap performa Aluminium – Air Battery.Sistem menggunakan aluminium sebagai anoda,tembaga sebagai katoda, dan kertas saring sebagaipemisah, dengan enam sel yang dirangkai seri danvariasi molaritas NaOH sebesar 0,5 M hingga 3,0 M.Tegangan dan arus diukur setiap 5 menit selama 30menit. State of Charge (SoC) dihitung berdasarkanpenurunan tegangan relatif, sedangkan State ofHealth (SoH) dihitung dari total energi yangdihasilkan. Hasil menunjukkan bahwa peningkatanmolaritas meningkatkan performa baterai.Konsentrasi 2,5 M menghasilkan tegangan awaltertinggi (7,35 V) dan arus 0,73 A. SoC menurunselama pengosongan, namun lebih stabil padakonsentrasi tinggi. SoH meningkat seiring naiknyamolaritas, dengan nilai tertinggi pada 2,5 M. Pada3,0 M, performa menurun, kemungkinan akibatreaksi samping atau korosi elektroda.Kata Kunci: Aluminium – Air Battery, molaritasNaOH, SoC, SoH,

The habit of leaving electrical devices running unattended can lead to electricity wastage and, in the event of a short circuit, can potentially cause fires. Electricity consumption by PLN customers in the household sector continues to increase every year, necessitating enhanced efficiency. One solution is to use IoT to monitor and control electricity usage. This research employs the design of an IoT-based smart plug capable of monitoring AC electrical variables such as voltage, current, power, frequency, and power factor, as well as controlling a relay to cut off the power supply. Testing was conducted using a multimeter and a single-phase energy meter as a benchmark for the designed prototype. Additionally, the IoT system's response time was evaluated. From testing the ZMPT101b sensor, a difference of 4.358 V was found compared to the benchmark device, while the ZMCT103c sensor showed differences of 68.4 mA, 61.7 mA, and 68.3 mA across three loads. The power differences for each load were 0.38 W, 0.74 W, and 0.07 W, respectively. Regarding energy measurement performance, a difference of 0.1 kWh across the three loads was observed compared to the benchmark device. The actuator used is a relay, which disconnects the power supply in the event of an overload. The device's current-limiting performance was demonstrated when one circuit detected an overload (>5A), causing the relay in that circuit to successfully disconnect the power supply. The IoT system implementation was carried out via a web server with a local IP, which was then connected to the internet using the ESP32 Power Monitor application on a smartphone. With ESP32 Power Monitor, users can view sensor parameter readings and control the relay status for each load.Keywords : IoT, smart plug, power monitoring, energy efficiency, remote control
