Designing Prototype User Interface Digital Library for Elementary School Based on Probability Bayesian

Recently of digital library technology is not only developed on the aspect of the system, but also in the interface design, because it has a significant role to reach the level of usefulness and success as source of knowledge. Digital library's interface should be developed and can adapt to the needs of children, who have different of ability and expectation when interact the user interface design than adult. This research aims to design the interface prototype digital library for elementary school students, based on the analysis of chosen existing library. Tests performed limited on the interface “simple search” form on the ICDL, with field observation approach methods, and the 6 task were completed over 15 minutes. Layout space used a single room setup when doing the observation. Data were taken from 12 elementary school students (7-12 years old), who come from three different schools. Processed analysed by Bayesian probability methods. From the results obtained, it can be concluded that the certainty of children had a difficulty when accessed forms simple search ICDL at the first used. From the analysis of the design 1 login register on the form ICDL display showed the probability of students choosing Register / Login influenced by his perspective and the time given is 0.5.Recently of digital library technology is not only developed on the aspect of the system, but also in the interface design, because it has a significant role to reach the level of usefulness and success as source of knowledge.

Peranan Aerasi Dan Silika Serta Lama Pemeraman Terhadap Kandungan Pupuk Cair Lumpur Organik Unit Gas Bio

Organic Sludge Biogas Unit (OSBGU) is a product that was generally less noticed by the owner. Filtering solids and liquids of OSBGU would be very helpful for feedstuffs and fertilizer plants. Giving aeration and silica in the fluid of OSBGU as long ripening treatment with 1, 2, 3, 4 and 7 days was expected to transform the liquid into a better liquid fertilizer of OSBGU. The results showed that the effect of treatment, fermentation time and the interaction among them on the content of liquid OSBGU manure on pH, organic C, N total, C/N ratio, and organic matter was highly significant (P<0.01), except for total N did not have differences (P>0.05). The study concluded that the role of aeration and the addition of silica and long ripening and their interaction was very influential on the content of liquid OSBGU manure on pH, organic C, C/N ratio and organic ingredients, except the N total. The study suggested to use aeration and if necessary by adding silica and fermentation time until on day 7 to improve the content of liquid OSBGU manure
