Abstract

Penelitian yang dilakukan adalah rancang bangun alat peraga praktikum berupa modul kontrol level air pada tandon dan bak. Output berupa pompa air dan solenoid valve. Pompa digunakan untuk mengalirkan air dari sumur ke tandon sedangkan solenoid valve digunakan untuk mengalirkan air dari tandon ke bak. Kerja pompa di pengaruhi level air di sumur dan tandon, kondisi awal sumur penuh (sensor level air sumur on) dan tandon kosong (sensor level atas dan bawah tandon off). Pada kondisi ini pompa bekerja beberapa saat kemudian sensor level bawah tandon on dan pompa masih bekerja. Pompa berhenti bekerja saat sensor level atas tandon berubah menjadi on (tandon penuh). Apabila tandon kembali kosong maka pompa akan kembali bekerja. Jika suatu saat sumur kering (sensor level air sumur off) maka pompa tidak akan bekerja, pompa akan bekerja kembali jika sumur kembali penuh. Kerja selenoid valve hanya dipengaruhi kondisi level air di bak saja. Saat bak kosong (Sensor level air bak off), selenoid valve (SV) akan bekerja. Ketika bak penuh (sensor level air bak on) selenoid valve (SV) akan berhenti bekerja. Sensor level air disumur dan bak digunakan mercury switch yang dimasukkan pelampung, untuk sensor level air tendon digunakan proximity capasitive.

Abstract

In the transition from the dry season to the rainy season, betta fish breeders are particularly affected. Betta fish cubs are prone to death. Betta fish fry are betta fish children after 1 to 7 days. The feedstock of betta fish cubs, namely water fleas, is greatly reduced due to overflowing water. Unstable temperature attacks the body resistance of betta fish cubs. This study designed and made a conditioning device for the growth of betta fish fry using PLC Zelio SR3B261BD and NodeMCU ESP8266.  Features of the tool consist of making artemia feed, distributing artemia feed, telling breeders to mix feed, controlling, and monitoring the temperature of the pond water. The results of the study showed that the device can work to hatch artemia eggs, distribute artemia to fry, notify farmers via telegram to mix feed, monitor the temperature, and maintain the temperature of the pond water in the range of 24?C - 27?C. The difference with previous fish farming research, this research adds a feature of making betta fish feed through the process of hatching artemia eggs.

Abstract

Public awareness of healthy lifestyles has increased the demand for fresh vegetables. However, limited land availability due to population growth poses a challenge for agricultural production. Hydroponics offers a solution without requiring large areas of land, yet its success depends heavily on controlling environmental parameters such as pH, temperature, and nutrients. This community service project aimed to implement smart greenhouse technology based on the Internet of Things (IoT) powered by renewable energy (RE) for curly lettuce cultivation at Nurus Sunnah Farm, Semarang City. The implementation stages included site surveys, system design and fabrication, installation, training, mentoring, and sustainability evaluation. The developed system utilized solar panels as an energy source and was equipped with three types of sensors (pH, TDS, temperature/humidity) integrated with ESP32 and an online monitoring platform. The results showed that the system was able to monitor and control hydroponic parameters in real time, with a pH sensor reading error of 0.0231 and a TDS sensor error of 0.0116. This innovation facilitates the management of nutrients, pH, and temperature, while reducing dependence on electricity from the national grid. The application of this technology has proven to enhance management efficiency, potentially maximize crop productivity, and support sustainable agriculture based on renewable energy
