Penelitian ini bertujuan untuk meningkatkan kreativitas dan prestasi belajar mahasiswa dengan menerapkan model pembelajaran Cooperative Problem Solving yang di dukung oleh Hierarki Konsep pada mata kuliah Pengantar Teknologi Informasi. Penelitian ini adalah Penelitian Tindakan Kelas yang dilakukan dalam dua siklus. Setiap siklus memiliki empat tahap: perencanaan, pelaksanaan, observasi, dan refleksi. Subjek penelitiannya adalah kelas Pendidikan Teknologi Informasi semester I FKIP Universitas Budidarma yang berjumlah 30 orang. Teknik pengumpulan data melalui pengamatan, wawancara, studi dokumen, kuesioner, dan tes. Teknik analisis yang digunakan dalam penelitian ini adalah deskriptif kualitatif. Berdasarkan hasil penelitian, dapat disimpulkan bahwa penerapan model pembelajaran cooperative problem solving yang di dukung oleh Hierarki Konsep dapat meningkatkan kreativitas dan prestasi pembelajaran mahasiswa pada mata kuliah Pengantar Teknologi Informasi pada mahasiswa Prodi Pendidikan Teknologi Informasi. Pada Siklus I, persentase kreativitas mahasiswa mencapai 60% dan meningkat menjadi 96, 67% pada Siklus II. Persentase penyelesaian aspek pembelajaran pengetahuan mahasiswa dalam Siklus I adalah 56, 67% dan meningkat menjadi 86, 67% pada Siklus II. Persentase penyelesaian aspek pembelajaran sikap mahasiswa pada Siklus I adalah 93, 33%, dan pada Siklus II meningkat menjadi 100%, dan penyelesaian aspek pembelajaran keterampilan mahasiswa meningkat dari 93, 33% menjadi 100%.

Diagnostic Efficiacy of Immunochromatography Technique for Detection of Viral Hepatitisinfection in Suspected Serum Specimens

A prospective study was conducted in order to evaluate the diagnostic efficacy of immunochromatography assays for qualitative detection of hepatitis B surface antigen and hepatitis C virus antibodies, using commercially available rapid test devices. Rural population of district Chakwal visiting primary care hospitals for screening of hepatitis B and hepatitis C virus infections was selected as study population. Coagulated blood specimens were collected from a total of 500 individuals; serum was separated and stored at -20 C till analysis. Necessary demographic information with previous exposure and screening history of each individual was also recorded in pre designed performa. The stored serum specimens were analyzed for detection of hepatitis B surface antigen and hepatitis C virus antibodies through immunochromatography technique (ICT) and enzyme linked immunosorbant assay (ELISA) using commercially available ICT rapid test devices and ELISA kits. Out of total 500 specimens analyzed through ICT for HBs Ag detection, 15 exhibited positive outcome for the infection whereas analysis of the same specimens through standard ELIS test revealed 16 true positives. One of the ICT tested specimens was therefore recorded as false negative. The sensitivity of rapid test device for HBs Ag detection was therefore 93.75% with 100% specificity, 100% positive predictive value and 99.8% diagnostic accuracy. Similarly 34 of the 500 ICT tested specimens exhibited positive outcome for hepatitis C virus infection whereas 37 true positives were recorded when same specimens were analyzed through standard ELISA test. The sensitivity of ICT rapid test device for HCV Ab detection was therefore 91.89% with 99.57% specificity, 94.44% positive predictive value, 99.35% negative predictive value and 99% diagnostic accuracy. The findings indicate that the rapid diagnostic immunoassays, in spite of requiring minimum time and equipment, are not comparable with standard ELISA for screening of hepatitis B and hepatitis C virus infections.
