Pothole’s defect is major damages indicated the road condition visually, and the structural defects due to some potential causes. Nowadays, new forms of remote sensing technique were widely used, but less studies in the application of low altitude multispectral mapping. The potential of multispectral images is its help better in resolution due to its spectral characteristic. Hence, it helps a lot in feature classification with proper training sample, classifier used, and spectral band composite. Thus, this study aims to extract the defective roads by using the multispectral image of Parrot Sequoia with low flight altitude. This study tries to detect a pothole's existence from band combination and supervised classification other than its common use which ultimately for agriculture purposes. The classifier used in this is Maximum Likelihood, Support vector machine (SVM) and Mahalanobis Distance. 15 different probability of band stacks of green, NIR, red edge, and red band were used as multispectral images. The comparison of the performance between the types of classifier and band combination was modeled and discussed in this study. Classifier algorithm maximum likelihood gives the lowest error of 0.108m² with a combination of NIR + red edge band. SVM gives the lowest error of 0.427m² with a combination of green + NIR + red edge + red band. While Mahalanobis distance gives the lowest error of -0.082m² with a combination of red edge + red band. Averagely, Mahalanobis distance gives the lowest error of 0.299m² of all bands used. Keywords: Road, pothole, UAV, multispectral, UAV and detection

Funding for education in Islam basically focuses on distributing education costs and burdens that must be borne by the community. Things that need to be considered in education financing are the amount of money that must be spent and where the source of the money is obtained. Thus, based on the source, the cost of education is obtained from the cost of education that comes from the government, the community, and the Baitul Mal. The main obstacle in financing Islamic education is due to limited sources of funds, low support for the community. In this case the thought about the source of education costs, at least the education providers must have planned it in detail because if the implementation process only depends on certain parties, in this case, the education providers are not serious in developing it. All these aspects are the concern of Pesantren in providing education to students, thus the educational aspect becomes part of the aspect of assessment that is very important in learning. The right attitude to respond to today's developments is expressed by the values of moral education developed through management functions to improve the quality of Islamic education in Islamic boarding schools. By implementing it in formal education, Pesantren education, informal education, and non-formal education, it will produce spiritual values, ethical honesty values, and tolerance values. Based on this view, the program implemented felt by all Pesantren residents through a good financial system.

The wake wash from passing ships can cause environmental damage. The wake wash is an important issue for naval architects and shipbuilders in concentrating on more environmentally friendly designs. This paper presents results of a parametric study of catamaran hull form to obtain low wake wash hull form configurations or low speed inland waterway boats. The study uses a Computational Fluid Dynamics (CFD) simulation, and model experiments were carried out for validation of the CFD software set-up. The study concentrates on the asymmetric catamaran hull form. The investigation is conducted on two configurations of hull form; Flat Side Inward (FSI) and Flat Side Outward (FSO) configurations. The investigation is conducted on a hull form with a Length to Beam (L/B) ratio of 12.2, 15.2 and 18.3 and a Separation to Length (S/L) ratio of 0.2, 0.3 and 0.4. The results based on wave height criteria at various longitudinal cuts have shown that the FSO configuration has a lower wake wash compared with the FSI configuration. Considering L/B and S/L ratios, hull forms with a larger separation or higher L/B ratios produce lower wave heights.
