Photovoltaic (PV) systems as a source of renewable electricity generation have experienced rapid development. However, PV systems have several problems, one of which is that the generated electrical power is unbalanced affected by temperature, humidity, irradiation, etc., which makes it difficult to obtain maximum power from PV. In addition, the difference in irradiation levels on each PV module caused by partial shading conditions can cause more than one peak on the PV characteristic curve. This study will compare the performance of the Firefly and Incremental Conductance algorithms in tracking the global peak in the PV characteristic curve. In simulating partial shading conditions, this research uses 6 PV modules connected in series-parallel with 4 test scenarios where each module has a different irradiation value. Simulation testing in this research uses MATLAB-SIMULINK software. Maximum Power Point Tracking (MPPT) simulation results show that from experiments using 4 different test scenarios, the Firefly algorithm obtained an average efficiency of 98.6437%. While the Incremental Conductance algorithm obtained an average efficiency of 78.3448%. So that the percentage of the superiority of the Firefly algorithm over the Incremental Conductance algorithm is 19.9607%.

The quality of pond water is very important for the successful cultivation of koi fish. The survival rate and growth of the fish are highly dependent on the water quality. If there are any changes in temperature or pH levels, the koi fish can become stressed and even die. The optimal temperature for the growth of koi fish is between 25°C - 30°C, while the optimal pH range is between 6.5 - 8.5. A monitoring system is used to measure the water quality of the koi fish using temperature and pH sensors, and the data is measured in real-time using the Internet of Things (IoT) to obtain good water quality and ideal temperature and pH values. With the Internet of Things (IoT), data can be sent and received quickly, taking about 0.5 seconds from the sender to the receiver, even if the distance is far as long as it is connected to the internet. This data is then sent to the Blynk server and can be displayed through the Blynk application on an Android device. If the water quality is not ideal, information will be sent to the koi fish cultivator's Android smartphone in the form of notifications on the Blynk server.

Water quality is important for koi fish health and is affected by the condition of the filter pond. The filter pond filters dirty water and delivers clean water to the pond so the cleanliness of the filter pond can be seen from the turbidity level of the water. The water pump is used to circulate water and it is important to perform maintenance on the water pump so that there is no decrease in performance. A monitoring system is needed using turbidity sensors and water flow sensors, and can be accessed via Android smartphones using Blynk. Each sensor is tested to test the difference value with the measuring instrument on each sensor. The turbidity sensor gets an average difference value of 2.31% and the water flow sensor gets an average difference value of 0.61%. This means that the sensor can read each parameter well. In addition, testing for the difference value of data transmission and notification on LCD and Blynk. Data transmission gets a difference value of 0% which means that the data sent by ESP32 can be displayed on LCD and Blynk and has no delay.

Solar energy is a renewable energy source, which can be used to produce electricity. The problem experienced at the locations of Proklamator Koi partners is that there are frequent power outages because they are located in rural areas that have poor electrical reliability, so the design of the Hybrid PLTS system was carried out as a solution to this problem. The purpose of designing this tool is to create a Hybrid PLTS system that is capable of producing an alternative source of electrical energy from solar panels as a backup power source. This system uses the main components of solar panels with a total capacity of 200WP, 30A Solar Charge Controller, 1000W Inverter and Automatic Transfer Switch. From the test results, it was found that the maximum output power produced by the 200WP solar panel is 151.33W. The electric power supply from the PLTS is capable of charging a12V 100Ah battery for approximately 8 hours from a 12V battery condition to 13.6V and can be used as a 48W water pump power supply for approximately 10 hours 30 minutes from 13.3V battery condition to battery reaches 12V or 50% battery capacity. The average inverter output voltage is 228.28V and the average ATS switching time in transferring the power source from PLN to inverter takes 0.288s and from inverter to PLN takes 0.151s. Then, the initial capital spent in designing this Hybrid PLTS system was IDR 5,688,500.00 with operational and maintenance costs of IDR 113,770.00 a year.
