Abstract

Efficiencies in the components of solar power generation systems (PLTS) are things that need to be known for an effective system design. The research of efficiency analysis on the components of solar power generation systems aims to determine the efficiency of PLTS system components, namely the efficiency of the solar charge controller (SCC), the efficiency of the inverter and the efficiency of the conduit between the battery and the inverter. The method used is an experimental method that designing a solar home system and measuring the quantity of electricity in each component of the system. The equipment used is a 2000 wp capacity solar panel, a 3000 watt inverter, a 60 ampere solar charge controller and a 400 Ah 24 volt battery. The results showed that the average solar charge controller efficiency was 80%, power losses of 20% occurred due to the limitation of the voltage and current at the SCC output to protect the battery from overvoltages and currents from the photovoltaic module. The results of the research show that the power wasted due to the protection of this SCC varies from 32 watts to 239 watts on the photovoltaic input power of 149 watts to 1239 watts. The average efficiency of an inverter is 84% and fluctuates from 71% to 97%, 71% efficiency occurs at a load of 38 watts while for an efficiency of 97% occurs at a loading of 277 watts. The average cable efficiency is 96% with fluctuations in cable efficiency because loading only 2% and This fluctuation is more stable than the fluctuation of the efficiency of the inverter and SCC, which is 26% each

Abstract

In today's modern era, the use of the internet of things (IoT) has been widely applied in various fields, almost all electronic devices are connected to the internet. Along with the development of technology, the application of this technology in the field of agriculture really needs to be considered. Due to the increasing need for plant monitoring and care. Therefore, the importance of plant care and monitoring so that plants can produce good quality.  In this research, an automatic plant watering system is designed that is connected to the internet network so that users can monitor plants so that they are maintained and produce plant quality. This system is designed using a NodeMcu microcontroller as the center of the system and as a data sender between systems and a web server. In this research, a monitoring system and automatic plant watering has been successful by reading the size of the moisture in the soil. The result is this system can provide water needs for plants. Then the system sends information to the website page that has been built so that users can monitor their plants anytime and anywhere.

Abstract

In general, we are certainly no stranger to seeing a tool called a simple pendulum swing for measuring the acceleration of gravity which is often shown during basic physics practicum courses. A simple pendulum swing with a manual measurement pattern is a physics practicum teaching aid that aims to measure the value of the acceleration of gravity with the form of a series of tools in the form of a small object, namely a solid ball and hung on a rope whose mass can be neglected. Then the other end of the rope is hung on a fixed hanger, after which if the pendulum is given a small deviation and then released, the pendulum will oscillate (vibrate) between two points, for example points A and B, with a fixed period T. Where the variables measured are the period (T), the mass of the pendulum (m), the angle deviation (O) and the length of the string (L) which will then be processed into an equation to find the value of the acceleration due to gravity. While the simple pendulum swing device with a digital pattern is a teaching aid for physics practicum whose purpose is also the same, namely to measure the value of the acceleration of gravity with the form of a series of tools that are also almost the same but the difference is the addition of intelligent electronic devices, namely the Arduino module as a control system and proximity sensors and push buttons. button as input device. The description related to the function of the electronic device for measuring the time variable of a pendulum when swinging is carried out using a capacitive proximity sensor with an Arduino internal timer facility. While the manual pattern usually uses a stopwatch.
