<![CDATA[In this era of globalization, technological developments are very rapid penetrated in all fields in particular. in the food and beverage sector..During a pandemic like this, as entrepreneurs, food and drink must adapt. Adaptation in question is hygiene in the process of making drinks and food. One example. it is an automatic drink making machine. that can help in the process. make drinks more practical and hygienic to keep more sterile. when making drinks in terms of blending drink ingredients. the process of stirring and pouring hot water. In an automatic drink making machine, in a supermarket there are still many weaknesses. ie the user is still making physical contact, such as approaching and selecting the menu and waiting for the process to complete. Based on the problems that exist among the general public, an idea was formed to design and manufacture an Internet of Things (IOT) based automatic drinking machine. which can help users in terms of making a drink. Users only need to select the drink menu that they want to make on the Android smartphone application that is connected to the access point, then the machine will carry out the process of making drinks. according to the menu selected in the application. The user only takes drinks to the places that are available. Based on the results of testing and analysis carried out on a machine this helps users to place orders and can enjoy drinks that are processed automatically.]]>

<![CDATA[Electrical Impedance Tomography (EIT) merupakan metode pencitraan non-invasive yang semakin banyak dikembangkan oleh para peneliti karena selain berbiaya rendah juga menggunakan bahan non-radiatif. Rekonstruksi citra dari EIT biasanya menggunakan perangkat lunak bernama EIDORS. Namun literasi penggunaan EIDORS masih sedikit dan kebanyakan peneliti berfokus pada hasil citra rekonstruksi saja. Oleh karena itu dalam artikel ini peneliti mencoba melakukan studi dengan melakukan variasi penyesuaian algoritma EIDORS agar diperoleh suatu citra yang akurat sesuai kondisi objek yang dicitrakan. Dari beberapa kali pengambilan data dan penyesuaian kode algoritma diperoleh dua kesimpulan bahwa akurasi pencitraan EIDORS dapat ditingkatkan dengan menambahkan kode program rotate_meas dan penyesuaian nilai amplitudo arus dalam library mk_stim_pattern dari nilai 1 hingga 0.01.]]>

<![CDATA[Penggunaan energi terbarukan semakin banyak diterapkan dalam kehidupan sehari-hari, khususnya pada pemanfaatan energi dari matahari dengan bantuan perangkat sel surya. Energi dari sel surya secara luas dapat digunakan dalam memenuhi kebutuhan berbagai macam perangkat yang memerlukan energi listrik, salah satunya dapat digunakan sebagai sumber daya utama untuk pengoperasian perangkat prototipe desalinasi dual output. Perangkat ini memiliki fungsi dapat memproduksi air tawar dan kristal garam secara bersamaan melalui proses distilasi. Dengan menggunakan sel surya sebagai sumber daya utama, maka proses tersebut sangat ramah lingkungan dan murah dalam biaya operasionalnya, namun banyaknya energi listrik yang dibangkitkan oleh sel surya sangat tergantung dari cuaca di sekitarnya. Untuk mengefisienkan penggunaan energi sel surya maka peneliti memiliki solusi dengan menerapkan sensor suhu sebagai kontrol otomatis dalam menghidupkan dan mematikan elemen pemanas pada proses distilasi. Hasil yang didapat berupa sistem kontrol menggunakan perangkat mikrokontroler dan sensor suhu yang mampu secara akurat mengendalikan elemen pemanas dengan menyalakannya saat suhu di bawah 100oC dan mematikannya saat suhu di atas 100oC sehingga tidak terjadi pemborosan listrik saat proses distilasi pada suhu tinggi.]]>

<![CDATA[Environmentally friendly problems have been widely studied in scientific journals, one of which is the use of gases that can damage the environment in a variety of cooling devices such as refrigerators and air conditioners (AC). In the past two decades, most of the refrigeration engines were still using Chloro Fluoro Carbons (CFC) gas, which had been researched in fact could damage the ozone layer. One alternative is to use freon gas to replace CFC gas as a component of air conditioning. Until now, CFC gas has been completely replaced by freon gas in the use of household appliances. But the use of this gas still has a bad side, especially for humans, when it inhaled in a certain amount can cause death. Therefore, in this study an air conditioning device with a main component was designed using thermoelectric TEC1-12706 which utilizes the Peltier effect in producing cold temperatures. This device is able to cooling a room with dimension 12 m2 in the interval of time 120 minutes to a temperature of 28.1 °C.]]>
