Abstract

Red chili is one type of vegetable that is quite important in Indonesia, both as a commodity consumed domestically and as an export commodity. Red chili production in Indonesia is still relatively low. The choice of chili plants in this research is based on the high market demand for chili commodities, however, to meet the demand which continues to increase every year, it is necessary to increase chili production through intensification or extensification. Weather factors have a big influence on the development of chili plants. During the long dry season, chili plants cannot grow well, this is due to the lack of water available for the plant's needs, which increases pest attacks. Another factor is excess soil moisture which can trigger chili plants to rot and die. To make it easier to cultivate chili plants, innovation needs to be carried out to help chili cultivators manage their chili plant cultivation, therefore by using the Plantation Irrigation System Automation tool using the Drip Method with Photovoltaic as an Energy Source it is hoped that this can be an innovation in managing the cultivation of chili plants, especially in controlling soil moisture in chili plants.

Abstract

Electrical energy is one of the basic needs for humans today, almost every activity we do is inseparable from the use of electrical energy, the use of electrical energy must be paid according to the amount and duration of electricity use in electricity management authorized by state-owned companies, namely PT. PLN Persero using kWh meter. In the postpaid type kWh Meter (Kilo Watt Hours), we cannot know the amount of electrical power that has been used in real-time.This research aims to design a system that can acquire power consumption in kWh andpower consumption costs (Watts) real-time by utilizing the ACS712 current sensor and voltage sensor circuit as input current and voltageand then processed by Arduino Uno for processing. The data is in an application interface, then the usage data is stored automatically in the data base local by the MySQL application.The results of this study are by comparing the calculation of power consumption (Watt) and the nominal cost of electricity in anapplication interface. After the data is obtained, it can be concluded that the readings from input the current and voltage sensor in this system are not accurate and unstable, so that the comparison of the value by the kWh meter is 4.8 kWh with a nominal cost of Rp. 7,745.76, while in this system design the power value obtained is 9.08 kWh with a nominal usage fee of Rp. 14,652.39. Then the difference in value between the calculation of kWh and the design of this system is 4.28 kWh, with a nominal difference in the cost of using it of Rp. 6,906.63.
