Abstract

Air is one of the most important elements of life for living things in the world. For humans, the air is an element that is very concerned because it is related to health. In Jakarta, the Air Pollution Standard Index (ISPU) is ranked second as the capital city of a country with poor air quality. Air quality in Jakarta is monitored by an Air Quality Index (AQI) of 160 with parameters in the form of very small pollutant particles with a diameter of fewer than 2.8 micrometres (PM 2.8). The purpose of this research is how we make a tool that can determine the quality of the air around us and can be carried (portable) anywhere easily. In accordance with the 4.0 industrial revolution that everything has been integrated with the Internet of Things (IoT) technology where the public can find out the air condition in real-time. In this study, the prototype method is used as a test. The main components are sensors consisting of MQ-6 (CO2 and smoke), MQ-7 (CO, LPG, CH4), MQ135 (Butane, AirQuality), and DHT-11 (Humidity, temperature). From the research that has been done where the air quality in urban areas has a low air quality index by measuring it using a prototype consisting of a gas sensor and Arduino microcontroller, which has been made to produce an average CO2 of 25 ppm, CO 2330 which has exceeded the threshold, while NH3 1.23 and C4H10 1120 are still below the threshold. These values are influenced by pollutants generated by transportation such as motorbikes, cars, and land transportation

Abstract

The benefits of the LKMA Cooperative are felt by the local community because with this cooperative farmers can continue to produce their agricultural land without fear of lack of capital. Currently, the number of members has reached 105 customers, where transactions have reached 180,000,000. This makes both administrative and financial processes very important in serving members. Currently, the bookkeeping carried out by cooperatives is computer-based using Microsoft Excel, but it is not yet efficient because cooperative administrators can only carry out transactions at certain times, such as monthly meetings, which results in long and time-consuming transaction process queues. Apart from that, the recording process still uses a card which is proof that the customer has paid the instalments, but manual recording has many weaknesses, including being left behind, damaged and even lost. Under current conditions, technology is needed to help cooperative administrators manage their cooperatives effectively and efficiently. The STMIK Himsya Semarang community service team saw an opportunity to assist LKMA cooperative administrators in managing cooperative finances using Cooperative Information System technology. This web-based cooperative information system application is made easier both from the admin and customer side because it uses the internet which can be accessed anytime and anywhere. All transactions carried out will be recorded in the database and can be seen in real-time, such as loans, payments, deposits and withdrawals.and publisher requirements.
