Nowadays, almost half of the world's population is exposed to air pollution. Sources of pollutants come from energy production, households, industry, transportation, and so on. One of the targets of the sustainable development goals agenda is to pay special attention to air quality to obtain the comfort of residents in their daily activities. To determine the level of air pollution in a certain place, an instrumentation system is needed that can measure the levels of pollutants in that place. This paper describes the development of a low-cost air quality measurement system using the MQ-7 and MQ-135 gas sensors. The detected gases consist of carbon monoxide (CO), carbon dioxide (CO2), and ammonia (NH3). The information from the sensor is then processed by the NodeMCU ESP8266 module which can then be accessed via a certain internet-of-things platform, namely ThingSpeak, and a cloud-based messaging service, namely Telegram. Experimental results show that the concentration of pollutants in a certain place can be known at any time from the ThingSpeak dashboard. In addition, an alert system is created to notify the user about the number of pollutant concentrations and the effects of the presence of these pollutant gases.

This paper proposed a modified 555 timer IC with only two comparators by eliminating the discharge transistor and SR flip-flop. A periodic square waveform can be generated by utilizing the interconnection of two comparators to provide ‘Set’ and ‘Reset’ conditions to each other. The simulation and experimental results confirm that the clock frequency generated by the modified 555 timer circuit is significantly higher and duty cycle adjustment can be made more precise and flexible than the commercially available 555 timer circuit. A frequency in the band of 1MHz to 89MHz can be generated by replacing the resistors, capacitor, and comparator specification in all possible configurations. As a result, a lower cost and higher efficiency on-chip reference clock generator can be realized to fulfill versatile future application needs.

Agriculture is one sector that has a maj or role in the national economy, where agriculture has a contribution of 13.53 percent of GP A in Indonesia. The most widely produced agricultural products are types of grains such as corn, rice, and beans. However, the price of these commodities is often controlled by brokers, several aspects that become the benchmark for brokers to price these commodities are the quality of the seeds. The quality of rice or corn seeds is considered good if it meets a very small level of moisture content. Therefore, sometimes farmers dry their harvests for a long time without knowing the level of water content contained in their harvests so that it will hamper the distribution of crops. The solution to the problems experienced by the farmers is a device that can detect the moisture content in harvested seeds at low prices and an easy-to-use process, and is supported by an AI system that can assist farmers in making decisions about crop quality. This device works by reading the level of moisture in the grain using a humidity sensor that is plugged into the harvest container such as sacks and others. If it is felt that the moisture level is low, the device will provide suggestions to the user to support decision-making through the OLED screen installed on the device. The features make it easier for users to make decisions whether the harvest is worth selling or not.
