Abstract

Maggot or Black Soldier Fly larvae is one of the living things that can be used as waste treatment technology, especially in organic waste. Factors that greatly affect the growth of BSF maggots are the feed media provided and environmental conditions. The environmental conditions referred to here are temperature, sunlight, and humidity during the life cycle of the adult fly phase inthe cage. The number of eggs produced will affect how many maggots will be produced. Processing organic waste is very dependent on the number of maggots, the more waste, the more maggots are needed. This research will present the design of fly cages that have been modified into IoT-based cages and how the characteristics of IoT devices for black soldier fly cages. The purpose of this research is to maximize the productivity of black soldier flies through technology. The results showed that the IoT-based cage design will be installed with a hose nozzle spraying mist outside the cage and a grow light lamp. Characteristics of IoT Devices using ESP32 microcontroller, DHT22 sensor to measure temperature and humidity, and TSL2561 sensor to measure Light Intensity, Actuators controlled through relays are Pump12V and Growlight T10, then data will be sent via Firebase RTDB and application. Optimal environmental conditions can increase the productivity of Black Soldier Fly. Keywords: Black Soldier Fly, Light Intensity, Egg, Temperature, Humidity, TSL2561, DHT22.

Abstract

A fuel cell is a device that can generate electricity using environmentally friendly fuel. It produces electricity through a chemical reaction between hydrogen and oxygen, with water and electricity as the outputs. Due to its ability to produce water and electricity, fuel cells are considered environmentally friendly devices. However, fuel cells also have some drawbacks, such as the requirement for a balanced ratio of hydrogen and oxygen, the need for precise temperature control, and the disposal of unused hydrogen gas into the environment. This results in wastage of hydrogen gas, which could be recycled for further processing. A hydrogen circulation system is designed to recycle hydrogen gas, allowing it to be reused by the fuel cell. The research involves the use of an air filter to clean the hydrogen gas, ensuring that only gas is processed. Additionally, a recirculation pump is utilized to push the processed hydrogen gas back into the fuel cell's input. Keywords: Fuel Cell, Circulation System, Air Filter, Recirculation Pump

Abstract

The Open Cathode Proton-Exchange Membrane Fuel Cell (OCPEMFC) is a promising technology for generating clean and efficient electrical energy. However, the performance of OCPEMFC is influenced by various factors, including the operational temperature range. The performance also depends on the chemical reactions occurring between hydrogen and oxygen with water, with electricity and heat produced as reaction products. In the reaction process of OCPEMFC, the rate and quality of oxygen supply to the cathode play a crucial role in enhancing the performance of OCPEMFC. This research aims to analyze the influence of temperature on OCPEMFC performance. OCPEMFC is a technology capable of producing environmentally friendly and efficient electrical energy. However, the performance of OCPEMFC can be affected by the operational temperature range. This study utilizes a system specifically designed to support temperature measurements using the DS18B20 sensor. The use of a blower in analyzing the temperature's effecton OCPEMFC performance is one solution to maintain the operational temperature range of OCPEMFC, which also affects the oxygen flow rate to the cathode. The application of a blower with Pulse Width Modulation (PWM) control is a solution to maintain the operational temperature range of OCPEMFC. The PWM value on the blower directly influences the generated airflow rate. PWM control allows adjusting the airflow to maintain the desired operational temperature. By increasing the blower speed, the oxygen flow rate can be enhanced, improving the efficiency of electrochemical reactions inside OCPEMFC. The use of a blower to control the temperature of OCPEMFC can help improve its performance, extend its lifespan, and support its use in cleaner and more sustainable energy applications. Keywords: FUEL CELL, BLOWER, TEMPERATURE, DS18B20 sensors , PWM
