The treatment of patients with acute respiratory failure due to COVID-19 needs ventilator machine support to provide oxygenation and ventilation processes. The most critical control in the machine is how to provide precision-inspired oxygen fraction (FiO2) to the patients during the treatment. Generally, the low-flow nasal cannula can provide 4-6 liters per minute of supplemental oxygen with approximately 37 - 45% FiO2. In this paper, we present high-flow and high-pressure oxygen mixing to provide up to 100% FiO2 and 60 liters per minute. The proposed system also employs the close-loop feedback control to achieve a desirable FiO2 set point. It can be used for a Continuous Positive Airway Pressure (CPAP) and Bilevel Positive Airway Pressure (BiPAP) ventilator systems with oxygen as well as a High Flow Nasal Cannula (HFNC) system for acute respiratory patient’s syndrome.

This research discusses the implementation of machine learning for modulation classification purpose. In order to proof the concept, 6 types of modulation have been selected, i.e., BPSK, QPSK, 8-PSK, 16-QAM, BFSK, and 8-PAM. Machine learning algorithm that was used in this research is support vector machine (SVM) and implemented using MATLAB’s classification learner. Data sets were generated using an ADALM-PLUTO SDR, and processed at baseband frequency range. Regarding the input predictors to the SVM algorithm, this research proposes multi classification features, such as wavelet transform-based, spectral-based, and higher-order statistical-based features. SVM algorithm obtained a classification-rule model with 91.4% of accuracy without any optimization applied.

Pulsed electric field (PEF) is one of several food preservation methods that apply short pulses of electricity for microbial inactivation and cause a minimal detrimental effect on food quality attributes. PEF technology aims to offer high-quality foods and long-time storage to customers. PEF technology is considered superior to traditional thermal processing methods for food quality attributes because it avoids or significantly reduces detrimental changes in foods’ sensory and physical properties. This paper described designing and fabricating a new milk pasteurization system based on the pulsed electric field, namely high voltage pulse power plant, agitator, heating, control panel with temperature sensor, treatment container. Testing and characterization of each sub-system and the system as a whole have been conducted, and the test results show that the pasteurization machine is running as expected.

Electrogastrogram (EGG) is one of the bio-signals that can be developed as a tool for early detection of digestive abnormalities. The use of features extraction and machine learning can be applied to accelerate the development of the system detection. In this paper, five features extraction and two classifiers are used as comparative study. The feature extraction includes Mean Absolute Value (MAV), Average Amplitude Change (AAC), Waveform Length (WL), Maximum Fractal Length (MFL), and Root Mean Square (RMS). ANN and SVM were designed as the proposed classifier. There are two classes that are designed for classification, namely Fasting and Postprandial stages. From the experimental results, it was found that the highest accuracy value is acquired when using SVM classifier and used five features extraction. The classification reached 82.3% that showed significant result. From the experimental results, it is found that EGG function as early diseases detection on digestive system is very promising i.e., Covid-19 effect to digestive system.

In this research, a radiation pattern reconfigurable (RPR) based multiple antenna was designed using a compact combination of a driven element and parasitic elements that operates at 3.5 GHz. The proposed antenna has the ability to change the radiation behavior to serve the user with better performance. The radiation characteristic of the antenna, especially the tilt angle could be reconfigured with the use of RF switches. The multiple antenna was designed on 94.4 mm x 110 mm Rogers substrate. First, an RPR antenna that uses parasitic patch array antenna was designed as a single element. Then this RPR was deployed as 2 x 1 RPR MIMO antenna using two types of configurations. Finally, the analysis showed that the multiple antenna arrangement using configuration II provides better results in terms of steering angle and gain.

A smart city is an area of the town that integrates Information and Communications Technologies (ICT). It has a multitude of smart environment services, such as smart energy and utilities, smart mobility and transportation, and smart living, combined with the day-to-day municipal administration to boost efficiency, enhance public services, and better the well-being of citizens. A reliable Internet of Things (IoT) network is required to deliver and enable these features seamlessly. Therefore, based on capacity and coverage planning, this research aims to plan the Random Phase Multiple Access (RPMA) network for smart city deployment in an urban area, namely Bandung city. It is obtained that the required number of gateways for capacity planning is twelve gateways, while for coverage planning, it is only one gateway. Once the calculation results on both capacity and coverage planning are acquired, these results are then simulated using a network simulator software, Forsk Atoll. The assessment of the simulations is done in two categories: the best signal level and the overlapping zones. The simulations results show that RPMA is plausible for smart city deployment in Bandung city with the range for the signal level received is from -70 dBm to -120 dBm with an average received signal level of -59.43 dBm, while the mean value of the overlapping zone is 1.24 server.

Non-contact vital sign detection using radar mounted on a flying platform is relevant for many applications especially for search and rescue operations in post-disaster situations. However, the vital sign is weak and easily covered by the noise and clutter. In addition, a small random movement from radar and/or humans will negatively affect detection accuracy. Thus, to address this problem, this paper proposes the detection and extraction technique of vital signs of nonstationary humans by applying sequential processing employing adaptive thresholding, image processing, and principal component analysis. The proposed method aims to be applied in detecting life signs using radar on a hovering drone. To imitate this scheme, in this study, the targeted human moves back and forth randomly in front of the radar. The results obtained by millimeter-wave radar demonstrate the ability of the proposed method to detect human respiration signs.

This paper presents the performance analysis of carbon composite materials with vacuum assisted resin infusion (VARI) method for electromagnetic interference shielding (EMIS) application. The structure was implemented using the VARI fabrication method and intended for shielding the synthetic aperture radar (SAR) instrument mounted on medium altitude long endurance (MALE) drone under development in Indonesian National Aerospace Agency. This structure is developed to shield and protect the radar subsystems from electromagnetic interference from other subsystems such as avionics and payload systems. The S-parameters measurements have been done in the anechoic chamber using vector network analyzer (VNA). The shielding effectiveness of the material is evaluated over 0.9 GHz and 5.3 GHz frequency bands using S11 for reflection factors and S21 for transmission factors to investigate the material characteristics. All of the material has fluctuated value. The quite stable value in 0.8–1 GHz S21 (dB) was carbon twill vinyl.
