Problems that often occur with CBT that have been developed include 1) low level and nature of test adaptation, 2) flexible size and unit of test administration, 3) user interface issues, 4) automated test assembly and test quality control, 5 ) security risks. Overcoming the problems above requires smart solutions, which are able to overcome current and future problems. One of the solutions offered to overcome this problem is to modify the old test model with a computer-based test model CBT-DE (Computer Bassed Test For Digital Entrepreneurship) using adaptive and integrated Mobile-Virtual Learning using an expert system. The use of an expert system in the CBT-DE model aims to make it easier to modify the system, can be used on various types of computers and other mobile devices which will be useful in integrating systems, has the ability to adapt, and has reliable information facilities. With this research, the CBT-DE (Computer Bassed Test For Digital Entrepreneurship) model uses Adaptive and Integrated Mobile-Virtual Learning which is able to provide material sharing and entrepreneurship education assessment tests to students in identifying students who have entrepreneurial talent and those who do not have entrepreneurial talent. . So that in the future the vision and mission of Dharma Andalas University can be achieved as a University based on Technopreneurship (technology and entrepreneurship). The research method used in developing this model is the research and development (R and D) method with the 4 D model. The expected output of this research will be a model, a product in the form of a CBT-DE application, publication in a Scopus indexed international journal, and proceedings Scopus indexed international seminar.</em></p> Sularno .

While sucking blood, the flea secretes a secretion that irritate the skin tissues it causes a massive itch. Fleas can be treated by chemical drugs like 1 % permethrin, but it did have side effect of itching, rusting, swelling in the skin and massive burning sensation. Citronella oil (Cymbopogon nardus) have a chemical content which are insecticidal among them is citronellal which can be used as a natural pediculosid. This research aims to formulate lotion preparations that are stable and effective as anti-fleas and increase the time of death of fleas compared to permethrin. The concentrations of citronella oil used for F1, F2 and F3 were 5%; 7.5%; and 10%. The three formulas were evaluated including organoleptic examination, homogeneity, pH, emulsion type, dispersibility, viscosity, skin irritation, cycling test, and anti-lice activity test. Data analysis used the Kruskal Wallis statistical test. Based on the results of the evaluation of the preparations, it was found that the organoleptic examination of the preparation of lotions FI, FII, FIII had a consistency of thick to liquid form, white to pale yellow, had a distinctive smell of citronella oil, FI test pH = 7.31-6.51, FII = 7 03-6,38 and FIII = 6,98-6,35, FI spread ability test = 6,15-7,75 cm, FII = 6,55-8,25 cm and FIII = 8,55-10,05 cm, emulsion type test FI, FII, FIII have emulsion type M / A, FI viscosity test = 2956-3107 cPs, FII = 2360-2677 cPs, FIII = 764-980 cPs, homogeneity test on FI, FII, FIII homogeneous, freeze and thaw test on FI, FII is stable while FIII is unstable, skin irritation test on FI, FII, FIII is not irritation, FI anti-flea activity test = 122-167 seconds, FII = 117-128 seconds, FIII = 69-90</em> <em>seconds.</em></p> Nesa Agistia Afrah Hafizah Emma Susanti Nofriyanti . ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 2024-02-12 2024-02-12 3 1 17 22 10.47233/jppie.v3i1.1269
