Abstract

Honey has many benefits. Thus, honey counterfeiting often occurs with the ever-increasing demand. However, many do not know how to distinguish between real and fake honey, even honey breeders and hunters find it difficult to tell the difference. The honey used to test the quality of honey is honey produced by Apis dorsata bees or wild bees, the nectar consumed by these bees is the kesambi tree, the kesambi tree that grows a lot on the slopes of Mount Tambora, Bima district. Honey contains a lot of antioxidants such as vitamin C, pinocembrin, chrysin, pinobaksin, catalase, and many other ingredients that are very beneficial for the health of the body. Testing the authenticity of honey using two sensors, namely a gas sensor and a color sensor, the tool has been connected to a database and web application to display test data. The web application can be accessed from any location as long as it is connected to the internet network. The results of the research are the ideal distance for measurements is carried out as far as 2 cm. The success rate in testing pure honey with a mixture of honey has different values, such as the value of pure honey has a gas sensor voltage of 3.3 volts while the value of mixed honey with 50% pure honey and 50% sugar, the value of the gas sensor voltage is 2.54 volts. Mixed honey has a voltage below 3 volts. The results of the color sensor test, namely the sensor output have different values, the RGB value for pure honey is red 206, green 246, and blue 182 while the RGB value for mixed honey is for 20% pure honey and 80% sugar mixture produces an RGB value of Red 156, Green 210, Blue 171. The color sensor can distinguish between real honey and mixed honey for trigona honey.

Abstract

Students with disabilities are special students who have equal opportunities to be independent and able to develop themselves. Through learning and increasing creativity and innovation, students with disabilities will be able to compete and contribute to progress and development of self-ability in the community environment. The rapid development of technology requires children to learn from an early age. The first step to foster children's interest in learning about technology is to create technology-based learning media. Therefore community service is carried out with the aim that students with disabilities can learn about technology and can create a work that is used as a medium for learning about technology. The PkM method used is the experimental method. The result of the PkM that has been implemented is that students can enthusiastically learn about technology such as making led circuits and water pump circuits. Six deaf students were able to successfully make LED circuits and water pump circuits for a miniature garden.

Abstract

Population growth is increasing every year. Population growth causes an increase in population density in a country. The largest population density is in urban areas. Fires in a city with a high population density will potentially cause greater damage. Material and non-material losses due to fire can be caused by not functioning maximally early warning systems, especially fire detection. In addition, other factors, such as system errors in detecting fires, can potentially cause fires. This research aims to build an intelligent system that can minimize building fire detection errors to reduce user material losses. The intelligent system can classify fire potential into four classifications, namely ”very dangerous,” ”dangerous,” ”alert,” and ”safe.” The method used in this research is Research and Development (R&D) with artificial intelligence using the Na¨ıve Bayes method, which has been integrated with the Internet of Things (IoT). This research shows that the Na¨ıve Bayes algorithm can be used to classify fire potential, proven by the overall system testing accuracy of 93.33% with an error of 6.77%.

Abstract

Penggunaan teknologi ponsel tidak dapat dilepaskan dari penggunaan charger. Charger umumnya digunakan membutuhkan energi listrik dari PLN dan generator. Panel surya dapat menjadi solusi sebagai alternatif baru untuk menyediakan sumber energi listrik. Induktif charging yang menggunakan elektromagnetik dalam sistemnya tidak memerlukan kabel saat digunakan. Alat ini menggunakan dua lilitan kumparan, yaitu lilitan primer yang terhubung dengan powerbank, dan lilitan sekunder untuk menerima dan mentransfer tegangan ke beban, dalam hal ini handphone. Hasil penelitian menunjukkan bahwa panel surya berfungsi sesuai dengan intensitas sinar matahari. Jika panel surya terkena cahaya matahari yang tidak maksimal atau cuaca berawan, tegangan output yang dihasilkan mengalami penurunan drastis. Baterai powerbank dapat menerima daya dari panel surya dengan baik, sehingga powerbank dapat terisi selama 460 menit dengan tegangan output sebesar 4 volt. Baterai handphone dapat menerima daya dari powerbank dengan rata-rata kenaikan setiap 1% baterai memerlukan waktu 8,5 menit. Sistem pengisian induktif dalam penelitian ini menggunakan panel surya 3 WP dengan sistem pembangkit sinyal gelombang sinus frekuensi 90 kHz dan dua kumparan sebagai sistem transmisi energi berbasis inductive charger.
