The tax revenues at Pratama Serang Tax Office in the latest five years have a decent percentage of accomplishment while the income of the tax itself is keep increasing, this thing is caused by several problem. For instance, taxpayer compliance, tax audit, and the disbursement of tax arrears. The objective of this research is to discover the effect of taxpayer compliance, tax audit, and the disbursement of tax arrears toward the tax revenues. This research applied descriptive statistic method by using quantitative approach. To discover the taxpayer compliance, tax audit, and the disbursement of tax arrears toward tax revenue agency, there will be a data testing by using multiple linear regression, classical assumption test, and the t test in hypothesis test. The result of the research present that the taxpayer compliance, tax audit, and the disbursement of tax arrears' variable are affecting the tax revenue at Pratama Serang Tax Office in 2012 to 2016.

Mobile phones are turning out to be increasingly ubiquitous and many users carry multiple phones to accommodate their changing needs. Here in this paper we present a virtualization technology called mobile phone virtualization which in turn creates a cloud computing service called Phone Call as a service (PCaaS). This service can purge the requirement of multiple phones and multiple Sims through the introduction of virtual sim cards. A wide number of virtual Sims providing various services is loaded to the cloud. The clients can obtain these services as per their requirement. This paper provides a concrete idea about the PCaaS cloud service by providing the design architecture of the Phone Call as a service (PCaaS) along with its implementation. This is followed by the design aspects of the same.

Nowadays the major difficulty faced by many countries is to monitor the recycling process. And there is an always emergent demand for low cost, very low power and condensed size monitoring systems with wireless communication systems, which can be used in different kinds of industrial environment applications. Consequently, the number of recycling spots has been steadily increasing. In order to ensure that the recycle bins, several monitoring solutions have been proposed. Still we have several limitations, such as requiring wires for power and/or communications and not being able to fit in all existing types of bins. This paper presents a wireless embedded solution for monitoring the level of the bins located in recycling spots. The proposed system automatically alerts a remote central station when a bin reaches a programmable filling level, thus avoiding the need to spot check if the bin is full and ensuring that the recycling spot is kept clean. The developed prototype required hardware-software co-design and aimed to meet the above mentioned requirements, resorting to the IEEE 802.15.4 protocol for wireless communications between all nodes in the network, each based on a System-On-Chip (SoC) CC2530 from Texas Instruments. Due to its wireless nature, the architecture requires a battery for power supplying the nodes. In recycling spot filling level readings of each bin is made up of ultrasonic sensor. The data collected by the monitoring platform is then sent to the remote central station that processes it in order to optimize routes and establish a scheduled collection of the recycling spots.
