Abstract

Blora Regency has a diverse artistic treasury. Various arts have been preserved until now. Besides attracting tourists to Blora, the art is also a manifestation of the high creativity of Blora people. The five distinctive arts of Blora Regency that are still preserved by the community are: Barongan Blora, Tayub Blora, Kadroh, Ketoprak, and Karawitan. Almost all of the typical arts of Blora Regency use gamelan instruments. Gamelan itself is a musical instrument not only owned by Blora Regency, but also an Indonesian traditional musical instrument that is worldwide. Gamelan for ancient people is considered as their identity, according to them traditional music is something to be proud of and liked. But why do young people today even dislike traditional music. One effort to attract the interest of the younger generation is to modernize the gamelan. Modernizing gamelan is not only to attract the interest of the younger generation, it will also be used as a solution to of preserving culture. Keywords: Arduino Uno, Capasitive Sensor, Saron Digital

Abstract

Electrical Loads are electrical equipment that is attached to the electrical system in a house or building. The operation of electrical equipment generally still uses a mechanical switch. The use of mechanical switches is considered less effective because controlling electrical equipment must be done directly through the switch. In this research, a prototype controller of an electric load was designed and built through voice commands given via an Android smartphone. The prototype made is based on the Arduino nano microcontroller. The prototype made is capable of controlling 10 electrical loads with a load capacity of 200 Watt each. The trials that have been carried out show that the prototype is able to execute voice commands with a success rate of 91%.

Abstract

The increasing number of motor vehicles in urban areas causes a decline in air quality due to emissions such as carbon monoxide (CO) and carbon dioxide (CO₂). If left unchecked, similar conditions may occur in Cepu City. This research developed an air quality monitoring and early warning system based on the Internet of Things (IoT) using an MQ-135 sensor to detect CO and CO₂ and a DHT22 sensor for temperature and humidity. The collected data are transmitted to the Thingspeak platform and sent to users via Telegram notifications. The device was tested for seven days at two different locations in Cepu. The results show that the system can provide real-time air quality information and early warnings to help the public take precautions against air pollution impacts
