This research is directed to sound absorption performance test on single-reflex bandpass type speaker box from a fiber of Areca Nut with polyurethane and gypsum matrix. The variables of this study change the frequency into 3 types namely, 125, 250 and 500 Hz and then modify the sound pressure into 10 types, namely, 31.5, 63, 125, 250, 500, 1000, 2000, 4000, 8000 and 16000 Hz. The preparation of the research material begins with a cutting of the areca nut, splitting, drying, picking fiber, chopping, and blending, sieving, making 3 types of sheet-shaped, mixing polyurethane with gypsum and printing specimens. Preparation of research materials in the form of box specimen type single reflex bandpass which is then tested with the method of buzz and sound pressure (SPL). While the value of voice pressure (SPL) circularly on the axis X, Y and Z obtained the highest average value 57 dB on the Y3 axis and the lowest average value of 51.59 dB on the X2 axis.

This paper introduces a new multi-purpose image watermarking algorithm which based on a hybrid of lifting wavelet transform (LWT) and Arnold transform for copyright protection and image authentication. In the proposed scheme, the original image is first decomposed by LWT into four subbands. Then the robust watermark which is a binary logo image is decomposed by Discrete Wavelet Transform (DWT) as such only the high frequency subband of the watermark are embedded in the low frequency subband of the original image. The fragile watermark is block wise self-generated from the original image and scrambled using Arnold transform which is later embedded in the spatial domain of the robust watermarked image. Self-generated fragile watermark supports self-authentication with high localization, whereas scrambling the fragile watermark increases the security of the algorithm. On the other hand, the lifting scheme approaches have almost one half the amounts of operations compared to the DWT based approaches. The overall system has been tested against various attacks and the results demonstrated that the robust watermark can be decoded successively under each attack. In addition, the proposed algorithm can detect any tampering attempts.

Wireless Power Transfer (WPT) is an attractive technology because it can supply power to IoT devices where battery replacement is difficult or the maintenance cost is high. Polarization Switching WPT antenna (PS-WPT antenna) is proposed in this paper. The polarization switching characteristic makes this design a good candidate for 5G-IoT sensors powered by using wireless power transfer. The 3GPP had standardized 5G-IoT [1]-[3] in June 2016. It provides deep indoor and wide area coverage extension of 20dB over GSM. The 5G-IoT network can support 50,000 users per cell and a battery life of more than ten years. The key problems of the 5G-IoT network protocol are the coordination and communication between large number of IoT devices and the base station. Using the PS-WPT antenna technology, the cell coverage could be separated into several partitions to wake up IoT devices within one partition of the cell to avoid the collision. The PS-WPT antenna has been designed and analyzed in this paper for the polling protocol to solve the problem of communication and collision between 50,000 IoT devices per cell within the base station.

The development of higher education is very rapid rise to the tight competition both public universities and private colleges. XYZ University realized to win the competition, required continuous quality improvement, including the quality of existing service facilities. Amenities quality services is believed to support the success of the learning activities and improve user satisfaction. This study aims to determine the extent to which the quality of the services effect on user satisfaction. The research method used is survey-based questionnaire that measure perception and expectation. The results showed a gap between perception and expectations of the respondents have a negative value for each item. This means XYZ service facility at the university is not currently meet the expectations of society members. Three service facility that has the lowest index is based on the perception of respondents is a laboratory (2.56), computer and multimedia (2.63) as well as wifi network (2.99). The magnitude of the correlation between satisfaction with the quality of service facilities is 0.725 which means a strong and positive relationship. The influence of the quality of service facilities to the satisfaction of the students is 0.525 meaning that the variable quality of the services facility can explain 52.5% of the variable satisfaction. The study provided recommendations for improvements to enhance the quality of services facility at the XYZ university facilities.
