The phenomenon that occurs in the load lifting system is the need for an efficient and reliable mechanism to move the crane hoist pulley vertically and horizontally. This study aims to design and test a crane hoist system that uses a DC motor and a stepper motor controlled by an L293D motor driver, and to develop an application based on MIT App Inventor to control the movement of the motor. The research method used is integrated hardware and software design, followed by testing the performance of the motor, driver, and the application developed. Testing was carried out under limited load conditions, to measure the motor speed, voltage, and current used at loads of 10 to 100 grams. The results of the study showed that the system can function well at varying speeds, and the motor is able to lift a maximum load of up to 100 grams with a speed that decreases according to the weight of the load. The MIT App Inventor application successfully controls the motor effectively via a WiFi connection with a maximum distance of 10 meters, and loads the operation of the crane vertically and horizontally. This study proves that the designed system is able to work optimally in lifting and moving loads, and the application developed provides easy and efficient control.

Stroke is a physical disability disease, which affects the upper extremity motor system. To support post-stroke motor rehabilitation, research on IoT-based elbow exoskeleton therapy devices that help elbow therapy with flexion and extension movements.

It can be concluded that the device shows stable performance in low (20 °) and medium (40 °) modes, but in testing with high mode (60 °) with a load of 2 Kg there is a decrease in servo performance which is indicated by the instability of the servo movement which shows an angle of 56 °.

Electricity is a primary human need today. Because nowadays all equipment is electronic-based, it allows the use of large amounts of power every day. It can be seen clearly that every year the use of electricity is increasing. An example that we can see the development of the times at this time, so many restaurants are emerging. Each restaurant requires a large amount of electrical power for their production equipment. With the need for large electrical power, a tool is also needed to be able to monitor the power. One of the advances that can be felt is in the field of control, currently with the network technology, computers can be solved, especially those based on the internet / IOT (Internet Off Things) which have grown rapidly making the problem of distance and time barriers can be solved solution and time. The interface used for operation is App Invetor, which system-wise, App Inventor consists of two components, namely the server and the client. The App Inventor server functions to store all program assets and provide other services related to application (project) file management.

In the era of globalization, technology increases efficiency in various human activities, including plant cultivation. Chili plants require special care, especially in meeting water needs according to ideal soil moisture, which is 30% -50% for chili. Conventional monitoring methods are inefficient because they require a lot of time and energy. A new breakthrough is needed to continuously monitor temperature, air humidity, and soil moisture. The designed tool will be placed in Cipadung Village to monitor soil moisture in chili plants, which require soil moisture that is not too high. This tool facilitates monitoring through the application, allowing automatic and manual watering. Soil moisture stability is also important for tomatoes, so watering can be regulated through the application display. This tool is useful for monitoring soil moisture levels effectively, supporting plant care with stable soil moisture needs, and facilitating the watering process through the application.
