In the use of computer devices that are done in recent use for data processing in the form of text, images or video that can be done easily and quickly. But in reality, there are events where the work, in the form of computer files, can be lost so that the required files are missing from the storage media in the computer. In this research will be discussed and presented a comparative analysis of four software for recovery of data that has been deleted. The applications used are OSforensics, GetDataBack, Disk Genius and Diskdigger. The capabilities of such applications in the recovery of deleted data have been tested and analyzed in flash drives. Based on the tests that have been done indicates that the fourth this application can work well in terms of finding deleted data. In addition, this application is also able to recover data or retrieve the already deleted.

Infrastructure construction made andesite’s demand has increased, particularly in Lampung Province. In this research, its distribution in West Sungkai of North Lampung is mapped based on Electrical Resistivity Tomography (ERT) data from 6 lines, each of them was 186 m in length. Due to its excellent vertical resolution, Wenner configuration is performed. The research area is part of Quarter Holocene Volcanic (Qhv) formation. Lajur Barisan members consist of volcanic breccia, lava, and andesite-basalt tuff; thus, resistivity modeling is built within this aisle. Subsurface resistivity model has been created using the non-linear inversion method with promising low error at the third to fifth iterations, which marks an acceptable value. Using 2D and 3D ERT modeling, it is estimated that there are three mains of rocks based on their resistivity value: sandy tuff with 65 – 212 Ω m; tuff with 212 – 655 Ω m; and andesite with resistivity more than 655 Ω m. Andesite within this area is likely lava andesite which spread from the middle to the West and north. It is located at 5 – 35 m in depths with the reserve estimation of andesite is about 1.65 million tons.

The purpose of this study was to analyze the strategic steps in building school branding. In addition, to see and analyze the supporting and inhibiting factors and their impact on increasing school competitiveness. The research method uses a qualitative approach, with data interviews and documentation studies. The results showed the strategic steps taken by schools in building school branding in increasing competitiveness, including: a) accreditation of expertise programs, b) ISO 9001: 2008, c) positive student behavior, d) student achievement both academically and non-academics, e) quality of graduates, f) superior expertise program. Supporting factors in building school branding in increasing competitiveness include a) the quality of teachers, b) the length of teaching teachers, c) teaching according to competence, d) good school promotion. While the inhibiting factors in building school branding in increasing competitiveness, include: a) motivation of students to increase competence according to expertise program, b) appearance of school buildings, c) lack of cleanliness, and d) location of the school in the middle of the campong. Keywords: strategy, school branding, competitiveness

Scientific literacy is one of the benchmarks for the ability of words in the divinity of daily life. This study is about problem-based learning (PBL) on learning physics from aspects of the word, not, and its implementation. The writing of this article uses literature reviews. First of all, the study problem is formulated, then while it is being experienced by existing and relevant researchers to be analyzed. Data collection techniques with electronic journals through google scholar, Scopus, Microsoft academies, Harzing’s Publish or Parish, and crossref. From the results of 20 articles from journals and 3 e-books. Based on the results of the analysis concluded that the Problem Based Learning model is a skill skill, thinking analysis skills, and scientific attitudes. The results of the journal synthesis show that there have been no research results linking the learning-based problem model to the variety of science literacy skills. This becomes a loophole and basis for advanced research and development of e-Module-based learning problems. The thing behind the varied skills of science skills is one of the problems one sign of learning there is a problem, student-centered learning, and learning in a small group.

financial administration is a process or all activities related to the financial goals that aim to achieve certain goals that have been fixed in an organization and later there must be financial reports that are given at the end of the activity. Financial Administration Process include the preparation of the RPS , preparation of RKAS: RKAS is a detailed plan of funding and program funding for one year, and official school budget documents are approved by the school principal and endorsed by the world of education intended for state schools and education delivery for private schools, and the RKAS period is valid for one academic year to come consisting of income and expenses. Is a report of all activities that will be carried out in the implementation of financial management in schools and reported in accordance with established procedures.)
