Abstract

Technology allows the process of managing catfish remotely, namely catfish managers do not need to manage feeding. In addition, the automated system makes it possible to preserve the quality of catfish as well as savings in feed costs. Today's automated tools mostly use a microcontroller as a controller. Microcontrollers can be programmed to execute commands as needed and at the same time become a form of automation system application in catfish management. In this study, the author designed a microcontroller-based automatic catfish feeding system. The microcontroller used is the ATMega 28 microcontroller which is connected to the RTC DS3231 module. This microcontroller is also equipped with a servo motor that works to move the fish feed valve automatically. The servo motor used is the MG996R servo which has a working voltage of 6V which is sourced from the power supply which is lowered in voltage using step down. The RTC DS3231 module is connected with the arduino uno R3 module, which is the control center of the automatic feed device. The microcontroller turns on following the fish feeding time, which is 8 am and 3 pm. The servo motor will work to open the valve twice in one day automatically with an angle or percentage of the feed valve opening by 35% - 45% for approximately 5 - 10 seconds and the feed that comes out is about 40-70 grams per 10 seconds.

Abstract

In aquaculture production, the number of fish cultivated in freshwater ponds contributes up to 1.1 million tonnes. Catfish(Clarias sp.) is a type of freshwater fish that is quite popular in the cultivation process. The feeding system still has many shortcomings, suchas the amount of feed that is not regular and the timing of feeding which is prone to being irregular. The automatic feeding system requiresa continuous power supply without being interrupted by blackouts from the PLN electricity network. One of the power supply alternatives isto create a power generation system (PLTS). Based on the research results, the solar module capacity is 500 Wp for 1 polycrystalline typemodule, the solar charge controller rating is 20 A, the VRLA battery capacity is 200Ah 12 V KIJO, and the inverter capacity is 850 VA. Theresults of calculations and planning of PLTS can supply electricity with a load power of 1867 watts/hour.

Abstract

The need for electrical energy in a region is increasing along with the growth of the population. Sources of electrical energy derived from fossils will run out over time because this energy is non-renewable. Thus, renewable sources of electrical energy must be developed and become a very urgent need for the community, including in the southern coastal area of ​​Malang Regency, East Java. The location has sufficient solar radiation potential and can be used to generate electrical energy. The development of renewable energy supports the self-sufficiency of the community in fulfilling electricity by utilizing the resources around them. This paper aims to examine the opportunities for developing hybrid power plants (electric generator sets and solar panels) in the southern coastal area of ​​Malang Regency using the HOMER software simulation. The results of the study concluded that generation using a hybrid system, with a COE value of IDR 6,972, an NPC value of IDR 615 (million) and a CO2 emission value of 5,992 kg per year is the recommended system configuration. The results of this study were then taken into consideration in designing a power generation system in the south coast region of Malang Regency.
