Banjir merupakan salah satu bencana alam yang dapat mengancam kelangsungan hidup manusia dan merusak infrastruktur bangunan, sehingga membuat manusia harus berusaha mencegah kemungkinan bencana tersebut terjadi. Baik berupa memberikan pengarahan pada masyarakat untuk menanam pohon dan membuang sampah pada tempatnya. Salah satu altenatif untuk mengantisipasi permasalahan tersebut adalah dengan membuat alat pendeteksi ketinggian air yang perlu diawasi ketinggian airnya agar tidak terjadi bencana yang tidak diinginkan. Pada perancangan alat pendeteksi banjir via gelombang radio ini menggunakan mikrokontroller Atmega8535 dan juga sensor air yang digunakan untuk mendeteksi ketinggian air. Sensor ketinggian air akan membaca nilai resistansi pada saat sensor terkena air. Sensor akan selalu mengirim data melalui gelombang radio yang terpasang pada unit sensor. Ketika mikrokontroller membaca adanya air pada sensor maka mikrokontroller akan mengaktifkan pemancar (Transmitter) dan mengirimkan data berupa bit sesuai dengan tinggi keadaan air. Data-data yang dibaca akan dipancarkan dan diolah oleh mikrokontroller pada rangkaian penerima. Hasil pembacaan ketinggian air dari tegangan yang terukur, sehingga pada nilai tegangan tertentu alarm akan berbunyi dan dari keadaan sensor tersbut di tampilkan pada LCD dan PC sebagai monitoring ketinggian air

AI programming by children using Snap! block programming in a developing country

The development of human civilization today can’t be separated from the Artificial Intelligence. To prepare for this, early education on Artificial intel-ligent should be done. Some activities have been done to support students making AI programs, for example Google AIY, Machine Learning for Kids website, the Wolfram Language, and the eCraft2Learn project. One of the new block pro-gramming languages Snap! has been extended to provide an easy-to-use interface that provides AI cloud services as well as other AI functions. However, there is little research about AI programming learning for children in developing coun-tries. This paper presents how the learning of AI programming using Snap! pro-gramming in Indonesia. The learning process was evaluated with 40 Senior High Schools and Vocational students. 84% students had some basic programming ex-perience but others had none. 70% students who had basic programming experi-ence felt that AI programming using Snap! was easy to understand, yet the stu-dents with no programming experience found it difficult. Even though mostly the students can answer the evaluation question about how AI works and all the stu-dents were keen on creating AI programs using Snap!. We concluded that Snap! programing worked to introduce AI to children and has encouraged children to explore AI programming. However, some improvements are required to improve the learning process of AI programing using Snap! in developing country. The improvements are presented in this paper as the result of this research
