Abstract

A shopping cart is an assisting tool in the commercial area where its function is as a temporary container for selected shopping items before the items are counted and billed. The cart becomes an indispensable tool in supermarkets. The more shopping items there are, the more energy is needed to manually push or pull the cart. This is considered not very effective in supporting consumer productivity in finding and fulfilling their needs. The aim of this research is to create a smart cart used in supermarkets, thus facilitating users in carrying shopping items. The design of the smart cart combines hardware and software. Arduino Uno serves as the main component with object detection around it using the HC-SR04 Ultrasonic Sensor and Bluetooth Module as the link between the cart and Smartphone. The cart is controlled by a smartphone using Bluetooth as the connection within a maximum range of 7m, powered by 4 DC motors and a 12V DC Battery. The maximum load capacity of this cart is 2,5 Kg. The cart's ability to detect objects is limited to a distance of <20 cm.

Abstract

The septic tank is a temporary waste disposal site, designed to be closed, there are two holes to drain the reservoir and another hole for evaporation. Septic tanks produce hazardous gases, for example sewer gas, have a pungent odor and are flammable, if the concentration is high, causing poisoning if inhaled, if in a closed room and there is a source of fire, it can trigger an explosion. Therefore, an automation tool is needed as a warning system for the volume of the septic tank and to neutralize the sewer gas level, which has been equipped with solar panels as battery chargers embedded in it. This tool consists of HC-SR04 to measure the remaining volume capacity, MQ2 detects and measures sewer gas levels, a fan to neutralize sewer gas, a buzzer for warning. From the results of this study, the HC-SR04 detects the remaining volume from 28% to 2%, meaning that the volume of the septic tank increases, so the buzzer is active as a notification. Furthermore, MQ2 detects gas concentrations from 2ppm to 64ppm, meaning that the gas concentration increases beyond the safe limit, which is 30ppm, causing the fan to work to neutralize sewer gas levels.

Abstract

Households are the largest contributor to waste, various types of waste are generated, ranging from organic, non-organic waste and so on. If each household produces 2 kg of waste every day, and the waste is immediately disposed of in a temporary landfill (TPS), then a very large amount of waste is buried in the TPS. Therefore, a tool is needed that functions to process waste that can be recycled into compost, namely waste or food waste classified as organic waste. The tool in question consists of a nema 17 stepper motor as a cutter and stirrer for garbage to mix with the soil, a YL-69 sensor as a soil moisture detector, a DS18B20 sensor as a soil temperature detector and two mini pumps as a water supply and EM4. From the results of this study, YL-69 detects soil moisture of 17% to 86%, meaning that soil moisture increases, so the stepper will be active to stir the soil and organic waste. Furthermore, DS18B20 detects soil temperatures of 25°C to 34°C, meaning that when the temperature is between 30°C to 34°C, the composting process takes place, the water supply and EM4 stop automatically. Keywords – Organic Waste; Compost; Microcontroller, DS18B20, YL-69.
