The remote control system on electrical equipment in the room can be fulfilled through the internet as an IoT (Internet of Things) implementation. All devices managed from one interface, so home appliances management delivered quickly and conveniently. The main contribution in this research is IP based controlling for rooms with control lights and vertical curtains, and also the temperature of the air conditioner (AC) with IoT Technology. The used hardware is Raspberry Pi 3 as a server, Relay, motor stepper, IR led Transmitter, and temperature sensor DS18B20. For implementation, an android application is built by MIT App Inventor 2. The results show that all features function correctly, but each device responds with a different delay value. Delay time response of a lamp, vertical blind, and AC is up to 1.5 sec, 2.1 sec, and 1.6 sec, respectively.electrical appliances, IoT, controlling system, smart room
Komunitas Sahabat Penyu di Dusun Mampie Kabupaten Polewali Mandar (Polman) adalah kumpulan masyarakat yang aktif dalam kegiatan pelestarian penyu dengan mengumpulkan telur penyu, melakukan penetasan, perawatan serta rehabilitas penyu guna menjaga populasi penyu yang semakin berkurang di daerah tersebut. Hal ini bertujuan untuk melestarikan penyu mengingat semakin berkurangnya populasi penyu yang ada di Polman khususnya di Dusun Mampie. Kegiatan yang dilakukan melalui pendekatan ke sejumlah pemuda dan masyarakat lainya yang selama ini aktif menjual telur penyu ke pasaran untuk tidak lagi memperjual-belikan telur tersebut. Kurangnya kesadaran masyarakat akan manajemen konservasi penyu, proses monitoring jumlah dan perkembangbiakan telur penyu yang masih bersifat tradisional serta permasalahan pendanaan yang masih sangat minim merupakan masalah yang dihadapi oleh Komunitas Sahabat Penyu. Oleh karena itu, kegiatan pengabdian ini menawarkan solusi terkait peningkatan keterampilan para anggota komunitas dalam hal Teknologi Informasi untuk peningkatan kesadaran masyarakat terkait konservasi penyu. Tujuan kegiatan Pengabdian pada Masyarakat ini adalah memberikan pengenalan keterampilan dan pelatihan Teknologi Informasi kepada komunitas Sahabat Penyu tentang pembuatan sistem informasi berbasis website dengan media Wix. Media ini adalah sebuah aplikasi yang telah banyak digunakan untuk membuat website mulai dari blog, online shop, corporate website, serta situs edukasi. Selain itu, pelatihan desain media periklanan sederhana juga diberikan, yaitu pembuatan brosur, pamphlet, poster dan flyer. Dengan keterampilan yang diperoleh dari proses pelatihan Teknologi Informasi yang diberikan oleh tim pengabdian Departemen Teknik Informatika dan Departemen Teknik Elektro Universitas Hasanuddin maka komunitas Sahabat Penyu dapat menciptakan sistem informasi komunitas yang dapat berfungsi sebagai ajang promosi komunitas untuk menjaga eksistensi sehingga otomatis dapat menumbuhkan kesadaran akan pelestarian populasi penyu dan meningkatkan donasi kepeduliaan masyarakat terhadap penyu.
Microorganisms such as bacteria are the main cause of various infectious diseases such as cholera, botulism, gonorrhea, Lyme disease, sore throat, tuberculosis and so on. Therefore, identification and classification of bacteria is very important in the world of medicine to help experts diagnose diseases suffered by patients. However, manual identification and classification of bacteria takes a long time and a professional individual. With the help of artificial intelligence, we can effectively and efficiently classify bacteria and save a lot of time and human labor. In this study, a system was created to classify bacteria from microscopic image samples. This system uses deep learning with the transfer learning method. Inception V3 architecture was modified and retained using 108 image samples labeled with five types of bacteria, namely Acinetobacter baumanii, Escherichia coli, Neisseria gonorrhoeae, Propionibacterium acnes and Veionella. The data is then divided into training and validation using the k-fold cross validation method. Furthermore, the features that have been extracted by the model are trained with the configuration of minibatchsize 5, maxepoch 5, initiallearnrate 0.0001, and validation frequency 3. The model is then tested with data validation by conducting ten experiments and getting an average accuracy value of 94.42%.
The river currents is one of renewable energy types. It can be utilized for electrical generation. This study discusses about design and testing of initial prototype of power plants based on river currents prime mover. The working principle of this prototype is to convert kinetic energy from water current into electrical energy. The prototype testing were carried out at several variations of river currents velocity: 0.6, 0.8, 0.9, 1.2 and 1.3 m/s. The testing at 1.3 m/s velocity produced 1300 rpm of generator rotational speed, 0.22 A of electrical current, 5.2 V of electrical output voltage and 1.14 Watt of electrical power output.
