Investigation On The Role of Cavity and Slit of Cavity Resonators to Sound Absorption Behavior

Slit resonator and also perforated resonator are few kind of room interior finishing. They act as sound absorbers. Gen-erally, they are constructed of at least three basic types of absorbers, such as porous, membrane and cavity compo-nents.These types of room surface finishing should acoustically provide aural quality for audience and even architec-turally contribute aesthetic value for interior finishing. To attain a well performance of interior finishing, composition of surfaces, textures and colors, motivate designers to explore slit and also perforated resonator as frequent choices. Configuration, dimension, composition and form of cavity or slit may give different and specific sound absorption be-havior as well as sound absorption ability and quality. Research that has been done leads to the objective to study the role of slit and cavity resonators as sound absorbers through experimental method in a reverberant chamber

Compliments Given by a Teacher in Symphpnia Music School Surabaya to High-, Mid-, and Low-ability Students

This research aimed at observing compliment and non-compliment feedbacks between a teacher at a private music school and her students who had different abilities. The data were the recorded piano lesson of each student and the analysis was focused on the compliments and exchange structures as directed by Holmes (1988) and Coulthart (1992). The findings showed that all students received more compliments than non-compliments. For the compliment, all types of student received ‘Good' token the most. On the second place high-ability student received ‘Very Good', while mid- and low-ability student got mitigation. As for the non-compliment feedback, high- and low-ability student got criticism the most and it was found that the frequency of no feedback in mid-ability student occured the most

STRATEGIC INFORMATION SYSTEMS PLANNING AND INFORMATION TECHNOLOGY FOR SCHOOL

As a foundation, At-Thoat school has a routine agenda every year, namely the Admission of New Students (ANS). Even though they have implemented by online, they have not been able to realize one day service. The speed and automation of ANS services greatly helps the acquisition of new students. Because competition for new students is competitive. In addition, the number of new students at At-Thoat has also greatly influenced the survival of the school. The solution offered in this study for this problem is to compile a strategic design for Information Systems (IS) and Information Technology (IT) using the Ward and Peppard method, which are design methods capable of producing IS / IT strategies that are in line with business strategies. The first stage in applying this method in this research is the analysis of current conditions, both the organization as a whole and the IS / IT aspect. The next stage is an analysis of IS / IT needs in the future. The final stage is the preparation of IS / IT strategic steps. To analyze each of these stages, analysis tools are needed, namely: SWOT, critical success factor. The implementation of the Ward and Peppard methods and their analytical tools were able to identify and recommend IS / IT needs at At-Thoat School for the next 5 years. However, the resulting recommendations must be adjusted to the priority scale, because of the various limitations faced.  

The effect of geometric structure on stiffness and damping factor of wood applicable to machine tool structure

Stiffness and vibration damping capability are important criteria in design of machine tool structure. In other sides, the weight of machine tool structure must be reduced to increase the handling capability. This paper presents an analysis of the effect of geometric structure on stiffness and vibration damping of wood structure. The stiffness was analysed using numerical method, so called finite element method (FEM), while the vibration damping capability was experimentally tested. Vibration testing was also performed to wood structures with sand powder filled into its rectangular hole to observe the its effect on damping factor. Simulation results show that the cross ribs structure yielded minimum mass reduction ratio compared to the three square holes as well as the single rectangular hole structures. While the vibration test results explained that the damping factor of Shorea laevis wood was higher than that Hevea braziiensis wood. The use of sand powder as vibrating mass in closed-box structure effectively increased the damping capability, for single rectangular hole structure the damping factor was increased from 0.048 to 0.07
