Cultivating mustard greens requires maintaining the ideal soil moisture level within the range of 50% to 70% Relative Humidity (RH). To fulfill water requirements and preserve soil moisture, irrigation processes are essential. Historically, farmers have employed manual irrigation methods, such as flooding entire agricultural fields, leading to water wastage and requiring significant labor. This research aims to develop an automated irrigation system based on soil conditions to assist farmers in the irrigation process. The automated irrigation system operates by responding to soil conditions. It initiates irrigation when the soil is dry and automatically ceases when the soil becomes adequately moist. This system utilizes Arduino as the central control unit, soil moisture sensors as input devices, an LCD for monitoring, and a water pump for distributing water to the agricultural fields through drip irrigation. The research methodology follows engineering design principles and encompasses three stages: design, installation, and implementation. The design phase involves creating the system, programming, and designing the drip irrigation system. Installation entails assembling the components of the automated irrigation system, while implementation involves deploying the system in agricultural fields and conducting tests. The research findings indicate that the automated irrigation system effectively irrigates when soil moisture falls below 50% and halts when it reaches 70%. Calibration tests reveal a 2% variance between the capacitive soil moisture sensor and the Soil Moisture Meter. The water requirement for a single mustard greens plant to reach the ideal soil moisture level (50-70% RH) is approximately 150 ml.

Daily life cannot be separated from the use of electrical energy, such as in homes, which often cannot limit it. Accompanied by technological developments so that the internet can be used in everyday life, the concept of the Internet of Things emerged. This concept has been utilized so that it can help maximize the use of electrical energy. Using NodeMCU which has an ESP8266 Chip so it is able to connect to the internet. The Blynk platform is used for users as a tools to find out in real time the power and costs of using electrical energy. Limitations on electricity use can be set. When the electricity usage has reached the usage limit, the buzzer will turn on automatically as a warning. Another additional control that can be carried out is cutting off electricity which can be done remotely. Cutting off the electricity flow is carried out using a relay which is a switch that is operated using electricity.

The increasing population growth in Indonesia also affects the need for a comfortable and safe shopping place. The increasing number of consumers at the same time causes lines, especially in the payment section. The purpose of this research is to try to develop a cashier with a self-service method to help speed up the payment process and reduce lines. This research uses a GM66 scanner to scan barcodes on product items to be purchased. While the 3200-DB TCS Sensor is used to detect the nominal money paid. Information on the price of goods that have been scanned is displayed on the LCD screen. After payment is complete, the shopping receipt will be printed. In the results of this study, a tool was obtained that can be used to automatically sum up the price of groceries. Additionally, this tool can also facilitate transactions for payment of groceries. However, in this study, the new payment transaction process can only use $50 bills, and there is no system for returning change.
