Abstract

Penelitian ini bertujuan menguji dan menganalisis perbedaan persepsi para mahasiswa akuntansi dalam memilih karir baik sebagai akuntan publik, akuntan perusahaan, akuntan pendidk yang bekerja di institusi pemerintah secara empiris. Penelitian ini juga menguji apakah gaji, pelatihan profesional, keprofesionalan, nilai sosial, tempat kerja, pasar tenaga kerja dan kepribadian adalah hal-hal yang dipertimbangkan mahasiswa dalam memilih karir. Populasi dalam penelitian ini adalah mahasiswa Universitas Diponegoro dan mahasiswa universitas Katolik Soegijapranata Semarang. 76 responden yang digunakan sebagai sampel didapatkan dengan menggunakan accidental purposive sampling. Sedangkan data didapatkan melalui questionaire dan hypotesis diuji dengan metode Kruskal-Wallis. Hasil pengujian telah membuktikan bahwa ada perbedaan persepsi mahasiswa dalam pemilihan karir gaji, pelatihan profesional, pengakuan keprofesionalan, linkungan kerja dan pertimbangan pasar tenaga kerja merupakan hal-hal yang bisa menyebabkan perbedaan persepsi dalam pemilihan karir. Sedangkan nilai sosial dan kepribadian bukanlah faktor yang menyebabkan perbedaan persepsi mahasiswa. This study aims to empirically examine and analyze the different perceptions of accounting students in choosing their careers that are as a public accountant, a firm accountant, an accountant or accounting educator who work in government institutions. Then, this study also examine whether financial rewards, professional training, professional recognition, social values, workplace, labor market, and personality become the students’ consideration in choosing their careers. The population in this study is accounting students at Diponegoro University and Semarang Soegijapranata Catholic University. The sample of 76 respondents are taken by using accidental purposive sampling. The data are collected through questionnaires and the hypothesis is tested by using the Kruskal-Wallis method. The test result has empirically proven that the differences of students’ perceptions in selecting their careers exist. The financial rewards or salary factors, professional training, professional recognition, work environment, and labor market considerations are the things that create the differences between students’ perceptions in choosing their career. However, social values and personality do not contribute to the differences of student perceptions.

Abstract

Mutation that occur in the virus help to avoid the host's immune system and are passed on to the next generation and synthetic compounds begin to cause influenza viruses to be resistant. The purpose of this study was to determine the effect of mutations and inhibiting compounds for neuraminidase on the H5N1 virus. All DNA neuraminidase 1 (NA1) sequences from the H5N1 virus in 2016 were downloaded through NCBI and converted into protein sequences in ExPASy. Amino acids are aligned with Clustal Omega in EMBL-EBI and HOPE servers to predict mutation effects. Amino acid sequence A/chicken/Subang/08160018-002/2016 is used to represent neuraminidase in Indonesia. Protein molecular modeling is done using Swiss Model and Fugue, the results of subsequent modeling in Ramachandra. Eight natural compounds from plants and two control compounds, zanamivir and oseltamivir were used as ligands, docked using PyRx and visualized with PyMOL and LigPlot +. As many as 11 amino acid sequences used there are 30 regions in sequences that are mutated and alter the function of neuraminidase which initially as exo-alpha-sialidase activity becomes hydrolase activity. The docking results show that rosmarinic acid, rosmanol, chlogenic acid, oleonolic acid, carnosic acid, caryophyllene and capsaicin have binding affinity between zanamivir and oseltamivir. Visualization shows that rosmarinic acid, chlorogenic acid, rosmanol, and capsaicin compounds are predicted to replace zanamivir and oseltamivir. Because mutations in neuraminidase alter the function of neuraminidase from exo-alpha-sialidase activity into hydrolase activity and rosmarinic acid, chlorogenic acid, rosmanol, and capsaicin compounds are predicted to be inhibitors for NA1.

Abstract

This research aims to know the influence of Discovery Learning on the cognitive abilities and science process skills of grade VIII students. This study uses the method of the Quasi-Experimental Sampling technique using simple random sampling. The research sample consisted of two classes, namely class VII-4 (Experimental Class), which used the model Discovery Learning, and VII-5 (Control class), using learning direct instruction, each class consists of 31 students. The research instruments in this study were a multiple-choice cognitive ability test consisting of 30 questions and a science process skills observation sheet consisting of 19 statements. Data were analyzed using prerequisite tests and t-tests (independent sample t-tests). Based on the results of data analysis, there was a significant influence (sig 2-tailed) < 0.05, where 0.000 < 0.05 on cognitive abilities and Science Process Skills in the experimental class. Based on the hypothesis test, it was found that there was an influence of discovery learning on the cognitive abilities and science process skills of grade VII students on the solar system material at SMP Negeri 13 Medan, 2024/2025 academic year.
