The IEEE 802.15.4 is the most common standard development protocol that is applied to the current industrial wireless sensor network. Specific standards and requirement for IWSN has been regulated by international standard organization, which consider security as one of the most important parameters that need to be considered. The encryption method is a commonly used method in data protection on a wireless sensor network system, but nevertheless there are still several limitations that need to be improved. In this work, a stream cipher Rabbit algorithm encryption was proposed as an alternative solution to securing IWSN for oil and gas industry sector. From simulation, the Rabbit algorithm with a 50% shorter key length compared to the RC4 algorithm has shown, a better-quality security algorithm of 9% for the entropy and 25.56% from minimum standard avalanche effect compare to RC4.

Currently, the type of battery that is widely used is a Lithium material battery. Lithium batteries have high power density than other materials, however lithium material is very toxic and dangerous, hence it requires special handling for operation. In this paper, a battery management system which can protect and do passive balancing of the battery from overcharging are carried out. The overcharging protection circuit is tested by monitoring the voltage and current values of each battery cell when it is charged, simultaneously. While the passive balancing circuit is conducted only by measuring the voltage value of each battery cell. Based on the measurements, the proposed circuit is able to protect from overcharging and to balance each battery cell at a voltage of 3.75 Volt with a charging current of 0.2 Ampere.

Because the ECG contains much of information regarding various heart diseases, the interpretation of an ECG is essential for monitoring heart health. Sensors, data acquisition, and pre-processing, such as filtering and denoising, can be done on a single chip. In line with that, the interpretation technique is also being developed, related to the speed of calculations and accuracy. In general, there are four stages of processing ECG information, namely, pre-processing, QRS detection, feature extraction, and classification. This paper proposes another alternative for ECG beat classification, that eliminates the pre-processing stage and combines feature extraction and classification in a single calculation stage, namely ensemble MLP. This method is expected to reduce computational costs while maintaining accuracy of 97% or more and a large number of classes, with 10 or more.

Electrical system in remote areas that cannot be connected to national electricity networks can be served by installing solar based off grid system. The battery bank energy storage as an important part of off grid PV system still have challenges in renewable energy systems and hardly depend on weather conditions. This article will focus on the characteristics of lead-acid battery charging and discharging against residential loads. The research methodology used by testing the rooftop PV system for residential load useage which consists of 2 units 200 Ah battery, 1 unit off-grid inverter 1500 VA, 4 solar panels 260 Wp/unit, and vary residential AC load. The PV loading test was conducted to achieve battery average internal resistance as well as state of charge (SOC). The results of battery characteristics testing show that when clear sky during the day, the charging current is sufficient to charge batteries, so even high load such as air conditioner operated, PV generation still capable in serving loads without termination. The system will be interrupted only if the inverter current limit exceed. This battery usage characteristics can be used as a basis for further demand side management of residential load powered by PV system to improve continuity supply.

A compact ultra-wideband (UWB) bandpass filter based on cross dumbbell stub with notch band structures is proposed and implemented. This bandpass filter (BPF) structure consists of directly feed line input/output. As the novelty, the cross dumbbell stub resonator was used and it was placed at the middle of the filter structure. By using this structure, the BPF not only has a compact size but also it has a wide-passband response. To remove unnecessary radio frequency (RF) signal, the rejection (notch) band was also proposed by using a novel technique which uses U-shaped defected microstrip structure (DMS). Moreover, the DMS is constructed at the center between crossed dumbbell resonators. This notch band structure has highly independent and it can be adjusted by modifying the U-shaped structure. Therefore, the specific frequency of the notch band can be selected independently without expanded number of resonator or stub. Furthermore, this BPF is fabricated on 2D - Duroid/RT 5880 substrate with permittivity (εr) of 2.2, thickness (h) of 1.57 mm, and loss tangent tand of 0.0009. Furthermore, the measured results show that the UWB-BPF has 3-dB passband from 3.0 – 12.2 GHz, with notch band at 6.7 GHz and the notch band has attenuation −22 dB. The design structure was verified by a good agreement between simulated and measured result. Overall, the proposed filter design has excellent performance in term of insertion loss, high independent notch-band, compact size, and implementable structures.

Face recognition is commonly applied to recognize an authorized personal in accessing secured personal information. Each personal owns a specific trait/feature on their face. Many researchers in this field make a pattern of the feature to analyze the characteristic of it. In this paper, author introduce a method called as an artificial neural network (ANN) to analyze and memorize the feature of the face likes how a brain work in remembering anything. Author used a back propagation (BP-ANN) approach of ANN to build a network mapping of the system. BP-ANN would equalize the ability to recognize the input pattern of task with the pattern used along the training process of the ANN. So, the percentage of the recognition process is reliable.

Hyperspectral imaging is often used to determine what components present in a scene of the earth’s surface. Each pixel in a hyperspectral image may contain of a pure material or a mixture of multiple materials due to the limitation of spatial resolution. To determine the abundance of each component in a pixel, a process called hyperspectral unmixing was introduced. In hyperspectral unmixing, each pixel in an image is compared to a spectral library to determine material types and their proportion in the pixel. In this study, we construct an algorithm to optimize the hyperspectral unmixing problem using L2,1 norm and Total Variation regularization to reduce reconstruction error. Specifically, our research aims to improve the unmixing results by applying L2,1 norm to impose collaborative sparsity on all pixels in the image and adding Total Variation regularization to improve the smoothness of resulting image. Our experimental results with both synthetic and real hyperspectral data show improvements in terms of lower RMSE and higher SSIM than those of other methods.

Random access channel (RACH) is the first step that needs to be conducted by any devices which require data transmission in modern cellular networks. Since LTE and beyond also often used to serve IoT application due to its wide coverage and availability, conserving energy is important. This paper presents a flexible preamble allocation scheme which is applied in RACH procedure and evaluates its energy consumption. The flexible preamble allocation enables base station to fine-tune its preamble allocation, which mainly used to prioritize H2H services over IoT ones. Such access prioritization translates in more efficient signaling transmissions during RACH procedure by reducing collision. The result demonstrates that the scheme can effectively reduce energy usage compared with the standard RACH procedure with shared preamble pool.
