Indonesia is an area of tropical islands with a tropical wet (humid tropic) which has two seasons of the dry season that occurred in May to October and the rainy season in November to April. In meteorological data monitoring system many of the facilities used include using thingspeak that can be accessed online and realtime wherever and whenever connected to the internet. The purpose of this research is to make monitoring system of meteorological sensor data in realtime by using data logger which is stored in thingspeak server using Android platform, Windows, iOS. The input of this research comes from meteorological sensor which is then processed using a microcontroller in the form of serial data so that it can be sent to the network which will be connected to thingspeak.com. On the Android platform the application is used thingsview, while on IOS using TS Connect application and on Windows using googlechrome, mozzila firefox or browser available on the PC client. The website address used on the Windows platform is https://thingspeak.com/channels/358620. Monitoring results have values corresponding to the data logger. The unsuitable value of the monitoring result is caused by the error that occurs on the sensor.

Development of microprocessor technology provides new ideas for creating smart devices, one of which is in the field of smart home. Smart home is a concept of a home integrated with a smart system and supported by technology that enables all work to be more effective and efficient. Mirror is a household device that is beneficial to humans. In this paper, a research on smart mirrors is explained. A smart mirror is a mirror integrated with an intelligent system so that it can display multimedia data originating from the internet using Raspberry as a computing tool, PIR sensor as a tool to control monitors, and DC fans as a tool to control temperature system. In this paper, the mirror was able to display information about time, weather, academic calendar, lab work schedules, prayer schedules, and academic news. A PIR sensor has a good accuracy when the device is placed at 180 cm above the ground and the distance between mirror and humans when mirroring is 70 cm. A DC fan was utilized to stabilize the system temperature in a range of 40 to 50 oC.

Electrical capacitance volume tomography (ECVT) is a method for determining the volumetric distribution of dielectric permittivity using the capacitance measurement principle. The determination of volumetric distribution of dielectric permittivity is important to regulate a process in which quantity of materials is a decisive parameter such as in industrial setting or vehicle sub-system. ECVT is a relatively fast and non-radiating method to observe spatio-temporal phenomena inside a process, making it a valuable technique. Sensor modelling and image reconstruction study are essentials in designing a suitable imaging system based on measurements from plurality of electrodes providing higher degree of information being observed. This research conducts sensor modelling with varying fuel objects in the interior of a cylindrical vessel. The capacitance value was simulated between a combination of eight electrodes mounted encapsulating the tube. Each measured electrode was given an excitation voltage as a source of an electrostatic field, which interacts with the object’s presence. The objects in this study are benzene, kerosene, and diesel fuel, along with reference dielectric values of water and air. Image reconstruction used the linear back projection (LBP) method. Matrix operations between sensor’s pre-defined sensitivity and capacitance values produce data that can be plotted into an image estimating the true distribution of objects. Capacitance values from modelling are proportional to the actual object’s permittivity. The reconstruction provides qualitative information on the proportion of fuel in the vessel based on the capacitance value. Images have distinct values according to the presence of different objects under investigation. The research contribution is a proof of concept in using capacitance tomography to detect different fuels inside an enclosed tank at modelling stage. In addition, this study serves as a guideline for implementing a non-invasive and non-intrusive system for determining proportions of materials of interests inside a certain setup.

Attendance is the documentation of presence and activity in institution. A software has been made to monitor the attendance using face recognition. The software uses camera to capture the image and works on any background color. The aim of this paper is to calculate its performance with sensitivity, specificity, and accuracy using Eigenface Algorithm and Principal Component Analysis (PCA) method. Face recognition in this paper is based on Eigenface algorithm, using pixel information from images captured by webcam. The image is represented using PCA method. The software is tested using different expressions and accessories in object’s face. The performance of the software indicates 73.33%sensitivity, 52.17% specificity, and 86.67% accuracy. The successful rate in identifying the face for distance testing is 70%, while successful rate of 85% is achieved for object wearing eyeglasses and veil (jilbab). Furthermore, the successful rate for various expression is 85.33%.

Paper ini membahas perancangan alat terapi oksigen dengan laju aliran udara tinggi atau biasa disebut dengan high flow nasal cannula (HFNC). Alat tersebut penting untuk memperoleh konsentrasi oksigen dan laju aliran yang ditentukan dengan menggunakan pencampuran gas tabung venturi. Mikrokontroler digunakan untuk mengolah data dan terhubung dengan WiFi sehingga dapat terintegrasi dengan sistem internet of things (IoT). Pengukuran dilakukan menggunakan sensor oksigen KE-25, sensor aliran udara FS-300A dan sensor tekanan MPX5700 untuk membaca parameter. Layar kristal cair (LCD) menampilkan data konsentrasi oksigen, laju aliran oksigen, tekanan dalam ruang, dan status katup solenoid. HFNC berhasil dirancang pada papan sirkuit cetak (PCB) dua lapis.

Pengujian tak merusak (NDT) berbasis arus eddy merupakan metode evaluasi objek tanpa melakukan kontak dan intrusi. Teknik ini penting digunakan dalam pemantauan kondisi suatu entitas berbahan logam. Keberagaman struktur target menjadi tantangan yang menuntut performa akurasi dan resolusi spasial dari instrumentasi arus eddy. Paper ini membahas pemodelan sensor pada domain dua dimensi menggunakan metode elemen hingga dengan bantuan perangkat lunak multifisika. Konfigurasi sensor kumparan induksi dikaji untuk variasi kondisi objek pada frekuensi operasi di bawah 1 kHz. Pada kumparan dengan inti udara, keberadaan cacat pada objek menghasilkan perubahan tegangan penerima sebesar 0,31%; sedangkan pada kumparan dengan inti besi sebesar 0,41%. Penambahan inti besi pada sensor kumparan induksi meningkatkan sensitivitas deteksi sebesar 86%. Prosedur ini dapat menjadi pemandu dalam mengembangkan sistem instrumentasi berbasis arus eddy yang efektif.
