In the previous research in Badut temple, it resulted in the conclusion that on the research path, there is a Badut temple foundation, at a depth of 0 m -1.5m, which is square wide. The results of this study require further research to detect the presence of a cavity zone because the presence of cavity zones has the potential for subsidence of the temple foundation. This study aims to determine the distribution of cavity zones under the temple foundation. Research in the first location around the temple building was carried out by scanning 8 straight lines, then combined and analyzed. Based on the results of the analysis, it is found that the cavity zones are spread from trajectory 1-8. The largest cavity zone is located in the corner of the intersection of lanes 1 and 2. The second location research was carried out in the pool in front of the temple; the results showed that the pool floor was dominated by the cavity and watery zone. Only a few points showed buried rock, which was shown by reddish-yellow color. Based on the data analysis, it can be concluded that around the temple, there are still many cavity zones, and there are still some buried rocks. As for the pool area, it is dominated by a cavity zone, so it is possible that there is still a lot of empty space under the ground floor of the pool, and it is watery.

Teknik yang digunakan untuk estimasi sumber suara (DOA) adalah Beamforming. Tujuan dari Estimasi ini adalah untuk mengoptimalkan gelombang yang diinginkan dan melemahkan noise. Pada penelitian ini dilakukan estimasi DOA menggunakan teknik Fast Fourier Transform (FFT) beamforming dengan  konfigurasi sensor secara Uniform Linear Array (ULA). Penelitian dilakukan dengan memberikan noise yang nilai frekuensinya tidak sama dengan frekuensi sumber dan frekuensi yang sama dengan frekuensi sumber. Hasil penelitian menunjukkan pemberian noise berpengaruh terhadap estimasi DOA dengan nilai error pengukuran ± 0.10.

Save and Credit Cooperatives of Syariah Financing BMT NU East Java is a bank that runs syariah principles. Differentiation is very important and must be owned by Islamic banks that have a strategy to retain customers who make credit by means of service excelent, mentoring and education, and emotional relations. The purpose of this study is knowing and analyze the effect of venture capital financing on the increase customer's business at KSPP Syariah BMT NU East Java and for obtain empirical data on whether or not there is an influence of venture capital financing. This study use quantitative approach with analysis simple linear regression techniques to SPSS 20 aplicatrion. While testing the hypothesis using the t test calculation. The population in this study amounted to 35 customers. Samples use saturated or census samples. Data collection techniques using questionnaires. The results is first, the t test of business capital financing variable shows 0,000 smaller than a (0,000 <0.05). t count> t table (7.909> 1.68957). This means that venture capital financing has a significant effect on business improvement. Second, R Square values obtained, amounting to 0.655 or 65.5%. This means that 65.5% of the regression models in this study in explaining the dependent variable (Increased Effort), while the remaining 34.5% is influenced variables not account in the result.
