THE DEVELOPMENT OF QR CODE BASED MOBILE ATTENDANCE INFORMATION SYSTEM USING SCRUM FRAMEWORK
As one of State ‘s Higher Education Institutions, the Kalimantan Institute of Technology (ITK) must perform the education and teaching function as mandated by the tri dharma perguruan tinggi, then the function is regulated in academic regulations and implemented in business processes of attendance. Currently, the attendances data are recapitulated manually at week 15 by Academic Staff. The attendance process that has been running has several problems, namely prone to violations of the actual meeting realization and attendance count, recapitulation time that takes a long time, risk of data input errors and loss of presence sheet. Based on these problems, the attendance information system is developed (SIAP ITK). This research was conducted with the agile software development methodology with the scrum framework. The results of this research is an android application following the business processes of attendance in ITK. Based on the testing result which was carried out during this research, SIAP ITK is considered capable of optimizing the attendance process that has been running at ITK
Selective Polarity-guided Extraction and Purification of Acetogenins in Annona muricata L. Leaves
Herein is described the selective polar-guided extraction and
column chromatography separation of annonaceous acetogenins from the leaves of Annona muricata L., commonly known as soursop. The objective
of this study is to obtain an acetogenin-rich fraction,
containing mainly annonacin, known to be present in the highest amount in soursop
leaves. Solvents with various polarities (ethyl acetate,
hexane, chloroform, ethanol, water) and their mixtures were used in the extraction, fractionation, and
isolation steps. The liquid chromatography-mass spectrometry analysis
of the isolate sample showed that annonacin, having a
molecular mass of 597.23, is the dominant acetogenin present. The amount of acetogenin isolated from the soursop leaf
samples was 242 mg/g, based
on the total lactone determination using the Kedde reagent. The cytotoxicity activity of the isolate sample was determined using the brine shrimp test. This study shows that there is a positive correlation between lactone content due to acetogenins and the
level of cytotoxicity in the fractions obtained. The low LC50
value of 1 ppm showed a significant
cytotoxicity of the ethyl acetate fraction
obtained, higher than cytotoxicity of cancer drug cyclophosphamide. High lactone content and a high cytotoxicity of the ethyl acetate fraction indicate the potential of A. muricata leaves as the source of bioactive
compounds for anti-cancer treatment
