The aim of this paper is to examine one of the most crucial factors in the “Technology Acceptance Model” proposed by Davis (perceived usefulness) in moderating the “DeLone and McLean” success model in the context of educational portal in Higher Education. Questionnaires were distributed online to 200 respondents and deserved to be analyzed. The respondents were regular students at the University of Bengkulu. Data analysis used Smart-PLS version 3.2.9. The research findings indicated an influence of “system quality, information quality, and service quality partially on user satisfaction” of the educational portal information systems. The result shows that perceived usefulness can strengthen the relationship between system quality, information quality, and service quality to the satisfaction of customer. This research contributes to the development of perceived usefulness variable as a moderating variable affecting the quality of a system, quality of information, and quality of service partially on user satisfaction and finding strategies needed by the University of Bengkulu effective and efficient information system.

[Leu]⁶-aureobasidin K 1 is an analog of AbK, in which aIle residue at the sixth position of AbK is replaced by Leu. [Leu]⁶-AbK 1 was successfully synthesized using a combination of solid- and solution-phase that has a difference with the previous method applied for the synthesis of other aureobasidin analogues, [2S,3S-Hmp]-AbL 2. The linear precursor was prepared by using solid-phase method with Fmoc strategy, in which an ester bond was constructed on the resin. The cyclic product was obtained from a solution-phase reaction of the linear precursor using HATU reagent. The crude of the cyclic peptide was purified using a column chromatography technique to obtain [Leu]⁶-AbK 1 with a percent yield of 5.31% that is higher compared to previous similar method for synthesis of [2S,3S-Hmp]-AbL 2. The purity level of cyclic product was analyzed using analytical RP-HPLC (t_R = 6.49 min) and analysis of structure using ¹H-NMR.
