Fuzzy logic is a logic that has values of fuzziness or ambiguity between true and false. Values in fuzzy logic typically range from 0 to 1. The theory of fuzzy logic is widely used for control systems in various fields. An automatic flower irrigation system is an automated watering device that can be operated with fuzzy logic. In this research, there are two main parameters: temperature and humidity. For the temperature parameter, five linguistic variables are used: cold, cool, normal, warm, and hot. Meanwhile, for soil moisture, three linguistic variables are used: dry, moist, and wet. The results of this research are the maximum setting points obtained according to the rules that have been defined. In this study, the maximum setting point is achieved with a high temperature and low humidity. The difference in output between the Mamdani and Sugeno methods is not very significant. The Mamdani method produces real number values, while the Sugeno method produces integer values. This difference is due to several factors, one of which is the difference in the use of formulas in the defuzzification process of each method.

Watering and fertilizing are very important to maintain the quality of the oil palm seeds. If the oil palm seeds are not watered regularly the soil will dry out while the oil palm seeds generally need to maintain adequate soil moisture and require a loose textured soil medium. So far, farmers have not optimally fulfilled the needs for water and fertilizer for oil palm seeds because they still use manual and traditional methods. Technological developments have made it possible to create irrigation and fertilization techniques automatically. In this study, a prototype of an automatic watering and fertilizing system was designed and realized for oil palm seedlings using the NodeMCU ESP8266 as the main controller in addition to RTC, humidity sensors, relays, water pumps, LCDs, and smartphones. RTC is used for fertilization scheduling, humidity sensors to sense soil moisture levels, relays as automatic switches that turn on and off pumps, water pumps to pump water and liquid fertilizer, LCD to display information, and smartphones to monitor conditions and processes of watering and fertilizing coconut seedlings palm. The test results show that the prototype tool can work well. When the soil moisture is read by the humidity sensor less than 30% (dry soil condition) then pump one is activated and when the soil moisture is more than 60% (wet soil condition) then pump one turns off. Furthermore, fertilization can take place according to a predetermined schedule where the second pump will automatically activate with a duration of 20 seconds for each fertilization period.

Technical shrinkage is shrinkage caused by impedance in generation equipment or transmission equipment to the distribution network so that there is energy loss. There are several technical shrinkage problems at PT. Perusahaan Listrik Negara (PLN) especially in Customer Service Unit (ULP) Lhokseumawe City and for now the cause is still unsolved, because this technical shrinkage problem will harm and have an impact on consumers and PLN itself. The purpose of the study was to optimize technical shrinkage in the distribution network to reduce energy losses that occurred during the electrical power distribution process in the distribution network of PT. PLN (Persero) ULP Lhokseumawe City. This study uses the help of Electrical Transient Analyzer Program (ETAP) software to simulate the power flow so that the depreciation value that occurs is obtained, then re-load adjustment is carried out to simulate again to determine the change in the depreciation value obtained after load adjustment. The results of the ETAP simulation show the depreciation value that occurred before the load adjustment was made by 76.7 kW after the depreciation load adjustment was adjusted to 59.6 kW. This means that this technical shrinkage can be suppressed by changing the feeder operation pattern and voltage drop value in accordance with the limitation provisions set in SPLN 72:1987.

AbstractThe reliability of off-grid solar power systems (PLTS) is highly dependent on battery performance. However, the battery shows limited response in supplying the load due to unstable voltage fluctuations, which causes the battery to heat up quickly. So there is a need for additional components in the system such as supercapacitors. Supercapacitors are energy storage devices with high power and energy density, short charging duration, long service life, and low risk of heat. This research aims to determine the effect of supercapacitors on the performance of off-grid PLTS systems. The research uses data from the specifications of the off-grid rooftop PLTS system at SMKN 1 Lingsar. Temperature and irradiation data are obtained from the data logger installed in the system. The research is a simulation in Simulink MATLAB. Several supercapacitor capacities were selected to determine changes in system performance. The simulation results show that the supercapacitor capacity has a significant effect on the current and voltage in the battery. Supercapacitors show the ability to absorb and release large currents in a relatively short time, thereby speeding up the battery charging process. Supercapacitors with a capacity equivalent to battery capacity have the best contribution to system performance. Keywords:Batteries; Off-grid Rooftop PV System; Supercapacitor.

This research focuses on the importance of maintaining generator output voltage stabilization using automatic voltage regulator (AVR), especially in dealing with load impacts and environmental changes. Through the implementation of internet of things (IoT), this system can be controlled and monitored remotely, enabling real-time monitoring without physical presence at the generator location. The main objective of this research is to increase energy efficiency by optimizing generator operation. System development methods include design, prototyping and testing stages. Test results show that the automatic voltage regulator is effective in maintaining a stable output voltage of around 220 V, even though the current varies according to the existing load. The power produced ranges from 23 to 670 W, with a power factor between 0.7 and 1. Despite a slight voltage drop to 217 V, the power factor increases to 0.93. The system uses NodeMCU to send data to Blynk and Google Spreadsheets servers, as well as servo motors and PZEM-004T sensors for control and monitoring. Overall, this research shows that the internet of things-based automatic voltage regulator system is effective in maintaining stability and increasing generator operational efficiency, with the ability to manage voltage, current, power, and power factor efficiently.

Fully controlled rectifier and BCR. The battery charge regulator (BCR) is the most important unit of an uninterruptible power supply (UPS) device. The BCR uses a 15 V/5 A transformer to lower the voltage so as not to overload the BCR components. Full control using four thyristors serves to supply voltage to the BCR, while the BCR serves to regulate battery charging. Forcing the battery to be charged at a constant voltage with the same current results in shorter battery life. Battery charging through the BCR is set to match the battery voltage, then allowing the BCR to control it by adjusting the phase voltage to 13.5 V for high voltage discharge (HVD) and 10.5 V for low voltage discharge (LVD). By using an IC Regulator combined with a relay as a voltage breaker for a fully charged battery, it will automatically disconnect to avoid overcharging the battery. Based on the performance test results of a fully controlled rectifier system using thyristors and BCR on a 12V/5Ah battery, the output voltage is as a fully controlled 12 V rectifier, the BCR switch can charge the internal battery in minutes with a current that varies between 2.1 A to 0.1 A.
