The fish attractor called "Piknet" is an instrument designed based on sound wave to maximize the fishing activity by gill-netters. The sound wave are used in "Piknet" ranged from 100-1000 Hz. The "Piknet" test was conducted to know the range of sound wave which has well responses by salt water fish. The result showed that the sound wave ranged 500...

... author: nurul.rosana@hangtuah.ac.id Two range of frequency will be examined to 18 fish in salt water. The frequency ranged between 100-500 Hz and 500-1000 Hz. The selection of these frequency range is based on related literatures. The test was conducted 3 times in 15 minutes for each frequency range to observe the fish responses. Piknet device is immersed and installed on the right side of saltwater tank (Fig. 3). Figure 1 show the device called Piknet. The cross-sectional dimension is 9 cm x 6 cm with 4.5 watts and 9 volt battery in power consumption. Figure 2 shows the step by step procedure of experiment. ...

As the empirical literature in educational technology continues to grow, meta-analyses are increasingly being used to synthesise research to inform practice. However, not all meta-analyses are equal. To examine their evolution over the past 30 years, this study systematically analysed the quality of 52 meta-analyses (1988–2017) on educational techn...
Cheating forms part of a complex emotional and cognitive process. However, although a relatively mundane phenomenon, instruments to evaluate cheating and its effects socially are scarce. This paper presents a five-stage approach aimed at providing validity to an instrument designed to assess cheating — specifically, its detection, and emotional rea...
Ground based optical telescopes are seriously affected by atmospheric turbulence induced aberrations. Understanding properties of these aberrations is important both for instruments design and image restoration methods development. Because the point spread function can reflect performance of the whole optic system, it is appropriate to use the poin...

A study of the diffusion process of sound wave-based attractor innovation in fishing groups needs to be done because the application of innovation requires an adaptation process so that one can adopt the new subject through the established stages. The innovation-decision process is a mental process by which a person or institution goes from initial knowledge about an innovation. This research aims to analyze the measurement model and the relationship between variables in the decision-making of Piknet innovation by fishermen in Bulak Surabaya. SEM PLS data analysis was used to determine the relationship between latent and manifest variables. The test results showed that the CR value is above 0.7; therefore, it can be said that the variable has been met. The AVE values for X1-X5, Y1 and Y2 are above 0.5. Therefore, each latent variable has a valid measurement model. The conclusions from the research are as follows: (1) The analysis results of the measurement model met the requirements with good characteristics. Therefore, it can be continued to the next stage of structural model analysis; (2) Furthermore, 11 eliminated indicator variables did not meet the standard requirements of the outer loading value ; (3) A significant relationship was found in the latent variables of X1-X5, Y1 and Y2; (4) Indicator variables related to the latent variable are X1.4, X2.1, X3.2, X4.1-X4.3, X5.1, X5.2, Y1.1-Y1.3 and Y2.1,-Y2.3. To develop this research, continuous research is needed by examining each of the variables used in depth.
... The attractor as a catching aid that is used can come from light or sound waves [8]. Sound wave-based attractors with a frequency range of 500-1000 Hz [9] are a fishing aid that can be used in three-layer gill nets (trammel net) to increase the catch. In the results of previous research, it was found that the fish's interest in the sound produced by the attractor produced a pattern, where the fish that had approached, turned away due to a change in the frequency of the sound produced by the tool, so it is necessary to research changes in the frequency range aimed at optimizing the catch. ...
... The method used in this research was experimental fishing, where the research was carried out by giving treatment to the object and looking for the effect of the treatment on the object under study. The instrument used in this study was a sound wave-based attractor that had been tested in the laboratory and in the water [9]. In this study, the frequency ranges used as treatment were the range of 500-1000 Hz by using 6 tools, each of which had a different frequency ranges, namely 500 Hz, 600 Hz, 700 Hz, 800 Hz, 900 Hz and 1000 Hz. ...
