The micro, small, and medium business (SMEs) actors of batik in Indonesia are currently facing many obstacles, especially in their effort to enhance their business performance. In order to enhance their performance, the business actors are demanded to develop a more unique and various batik motif/design and to enhance their product innovation. This research is to empirically test the effect of batik motif variables and product innovation on performance, by using organizational learning as moderation variable. The samples of this research is 90 micro, small, and medium business actors of batik from two regions in the province of Central Java; the city of Semarang and Semarang Regency. Data analysis uses SPSS program of version 22 by using Structural Equation Modelling (SEM). Research finding proves that : 1) Batik motif has significant effect on performance, 2) Batik motif has significant effect on organizational learning, 3) Product innovation has significant effect on performance, 4) Product innovation has significant effect on organizational learning, 5) Organizational learning has significant effect on performance. Organizational learning moderates the correlation between batik motif and product innovation with performance. Research finding proves the enhancement of product innovation and addition of batik motif/design needed to enhance business performance.

This study aims to identify prospective chemistry teachers� difficulties in comprehension the subject of polar and nonpolar covalent bonding. In addition to that, attempts were also made to determine how they interpreted the nature of force in covalent bonding. The study was conducted in qualitative research method. Three different concept cartoons were used for data collection. 15 prospective chemistry teachers were included in the study. All of the participants were chosen in purposeful sampling method. The data collected were put to content analysis, consistently with the nature of qualitative research studies. Following the analyses, the prospective chemistry teachers� levels of comprehension the subject were revealed and the issue was discussed.

It is seen that software industry has led to development of various technologies but its failures are still unseen. Software system failures have occurred like ERP project failure in Jordan, Therac-25 (radiation therapy machine), Arianne 5(Europe�s rocket), and automated airport baggage handling (DIA) and malfunctioning of GPS systems in US. The paper deals with illustration of project management strategy steps by taking case study on GPS system into consideration.

The article deals with the optimization of logistic flow of selected company in the area of software module Process Simulate. The aim is to design a logistics flow, which will reduce machine downtime, number of workers during the operation of CNC centres or achievement the elimination of redundant manipulation steps of direct staff. Modelling and simulation of workplace in a software module Process Simulate enables to rationalize it in virtual environment, which will contribute to cost savings that are expended in the process of direct implementation of the proposals in practice.

Nowadays, there are so many attacks on the network system. And most of the big company hired the great network analyst and network security officer to defend the network. \n Every network system used the Intrusion Detection System and Intrusion Prevention System to detect and defend from the attacker. There are many types of IDS such as Snort, Sguil, OSSIM, OSSEC and many more. In this proposed project, we will demonstrate on how the snort detect the attack.\nSnort is an open source network intrusion prevention and detection system developed by Source fire. It combines the benefits of signature, protocol, and anomaly-based inspection methods and uses as a control system to monitor all network traffic and prevent network from any attack. Snort is compatible with open source operating systems and provides a good security services to network if configured with Linux open source operating systems.
