Present research expresses an experimental investigation on nanoparticle use to enhance Solar still (SS) yield. Manganese Oxide (MNO2) is selected as a material and used in SS. The nanomaterial added with the black chrome paint of SS walls increase weight concentrations (WC) MNO2 have been from 20% 50 see its effect It has observed that heat transfer water temperature enhanced by paint. improved yield also 19.5% compared alone WC 20–50%. MNO2nanoparticle's payback time 82 days at than 98 days.
The development of higher education is very rapid rise to the tight competition both public universities and private colleges. XYZ University realized win competition, required continuous quality improvement, including existing service facilities. Amenities services believed support success learning activities improve user satisfaction. This study aims determine extent which effect on research method used survey-based questionnaire that measure perception expectation. results showed a gap...
Implementation of Decision Support System for various purposes now can facilitate policy makers to get the best alternative from a variety predefined criteria, one methods used in implementation is VIKOR (Vise Kriterijumska Optimizacija I Kompromisno Resenje), method this research got results with an efficient and easily understood process computationally, it expected that study parties develop model any solutions.
The steganography process combines mathematics and computer science. Steganography consists of a set methods techniques to embed the data into another media so that contents are unreadable anyone who does not have authority read these data. main objective use base64 method is convert any file in order achieve privacy. This paper discusses encoding using base64, which schemes same binary form series ASCII code. Also, EoF technique used text performed by Base64. As an example, for mechanisms...
In the management of education is not uncommon educational institutions sometimes receive sources funds from outside, one which comes Department Education in implementation its duty to provide allocation called Special Allocation Fund (DAK). This assistance APBN revenues areas devoted schools help fund special activities such as addition or improvement school facilities and infrastructure. The application this grantee needs use a Decision Support System (CMS) allow decisions be generated...
Decision Support System is a system commonly used to assist management in assisting decision-making top managerial sections, Multi-Criteria Making (MCDM) one of many methods that can be select the best alternative from number alternatives based on certain criteria, utilized Elimination Et Choix Traduisant la Realite (ELECTRE) method works concept outranking using pairwise comparisons each appropriate this paper applies ELECTRE web application employed for input and output dynamic...
Decision support systems are part of computer-based information (including knowledge-based systems) that used to decision making within an organization or company. The system provides a semi-structured decision, where no one knows for sure how decisions should be made. Recruitment employee recruitment in PT.Waspada Medan always through some tight selection before set accepted as employees at Medan. There several criteria must owned by each participant requirement become To get the best...
The aim this study is discussed on the detection and correction of data containing additive outlier (AO) model ARIMA (p, d, q). process using an iterative procedure popularized by Box, Jenkins, Reinsel (1994). By method we obtained models were fit to AO, added original coefficients from iteration regression methods. In simulation that contained AO initial are (2,0,0) with MSE = 36,780, after Zt 0,106+0,204Zt−1+0,401Zt−2−329X1(t)+115X2(t)+35,9X3(t) 19,365. This shows there improvement...
Improving the quality of human resources that can be done with intelligent organizing carefully at level Senior High School. In order for participant to follow intelligently, every should not only have achievement and general knowledge but also must experience in following smartly before. this case, both Teachers Principals are constrained selection such discerning participants. For use a computer-based information system reduce constraints participants carefully. Decision support is assist...
Symmetric type cryptography algorithm is known many weaknesses in encryption process compared with asymmetric algorithm, symmetric stream cipher are that works on XOR between plaintext and key, to improve the security of done improvisation by using Triple Transposition Key which developed from Cipher also use Base64 for ending process, experiment ciphertext produced good enough very random.
Currently, data security is crucial so as not to fall into the hands of irresponsible, steganography and cryptography a technique commonly used secure information from irresponsible parties by using computational algorithms such Pixel Value Differencing Algorithm on process GOST (Government Standard) for cryptographic process, that insertion messages (steganography) in image will be encrypted first newly inserted, this expected increase confidentiality integrity because add changing...
The development of technology is very fast, especially in the field Internet that at any time experiencing significant changes, also supported by ability human resources, Keylogger a tool most developed because this application rarely recognized malicious program antivirus, keylogger will record all activities related to keystrokes, recording process accomplished using string matching method. method keyboard help admin knowing what user accessed on computer.
