ANALISIS KESALAHAN MAHASISWA PENDIDIKAN MATEMATIKA DALAM MENYELESAIKAN SOAL NILAI MUTLAK PADA MATERI BILANGAN REAL

Tujuan pendidikan dalam pembelajaran dikatakan tercapai apabila mahasiswa mampu memahami, mendalami matematika dan mampu mengaplikasikannya dalam menyelesaikan masalah yang ada. Penelitian ini mempunyai tujuan untuk mendeskripsikan kesalahan mahasiswa dalam menyelesaikan  soal nilai mutlak pada mata kuliah Analisis Real. Penelitian ini merupakan penelitian kualitatif, dengan menggunakan pendekatan penelitian yang dilakukan adalah mengamati kasus yang dilakukan mahasiswa dalam mengerjakan permasalahan dalam matematika yang berbentuk soal. Adapun subjek dalam penelitian ini adalah mahasiwa pendidikan matematika Fakultas Keguruan dan Ilmu Pendidikan Universitas Muslim Nusantara Al-Washliyah Medan semester VI  kelas A Tahun akademik 2018/2019. Metode pengumpulan data yang digunakan pada penelitian ini adalah menggunakan metode tes dan wawancara. Penelitian ini dilaksanakan pada bulan April 2019.  Sebelum peneliti melakukan analisis, peneliti memeriksa keabsahan data agar memperoleh data yang valid. Selanjutnya dari data yang sudah valid baru dianalisis yang kemudian ditarik suatu simpulan. Dari hasil penelitian didapatkan hasil bahwa, mahasiswa melakukan beberapa kesalahan yaitu : kesalahan dalam menemukan konsep nilai mutlak, Kesalahan konsep dalam penggunaan tanda pertidaksamaan, Kesalahan dalam langkah – langkah penyelesaian dan kesalahan tidak melanjutkan proses penyelesaian. Sehubungan dengan hal tesebut, penyebab kesalahan mahasiswa dalam menyelesaikan soal matematika dapat digolongkan menjadi tiga yaitu: mahasiswa itu sendiri, dosen dan fasilitas (buku acuan) yang digunakan. &nbsp

Direct evidence of ZnO morphology modification via the selective adsorption of ZnO-binding peptides

Biomolecule-mediated ZnO synthesis has great potential for the tailoring of ZnO morphology for specific application in biosensors, window materials for display and solar cells, dye-sensitized solar cells (DSSCs), biomedical materials, and photocatalysts due to its specificity and multi-functionality. In this contribution, the effect of a ZnO-binding peptide (ZnO-BP, G-12: GLHVMHKVAPPR) and its GGGC-tagged derivative (GT-16: GLHVMHKVAPPRGGGC) on the growth of ZnO crystals expressing morphologies dependent on the relative growth rates of (0001) and (10 (1) over bar0) planes of ZnO have been studied. The amount of peptide adsorbed was determined by a depletion method using oriented ZnO films grown by Atomic Layer Deposition (ALD), while the adsorption behavior of G-12 and GT-16 was investigated using XPS and a computational approach. Direct evidence was obtained to show that (i) both the ZnO-BP identified by phage display and its GGGC derivative (GT-16) are able to bind to ZnO and modify crystal growth in a molecule and concentration dependent fashion, (ii) plane selectivity for interaction with the (0001) versus the (10 (1) over bar0) crystal planes is greater for GT-16 than G-12; and (iii) specific peptide residues interact with the crystal surface albeit in the presence of charge compensating anions. To our knowledge, this is the first study to provide unambiguous and direct quantitative experimental evidence of the modification of ZnO morphology via (selective and nonselective) adsorption-growth inhibition mechanisms mediated by a ZnO-BP identified from phage display libraries

HOW TO CALCULATE THE SQUARED NUMBER ?

Penelitian ini bertujuan untuk mempermudah siswa dalam menyelesaikan soal bilangan kuadrat pada siswa kelas VII. Jenis penelitian ini adalah deskriptif kualitatif dengan sampel penelitian adalah siswa kelas VII dari berbagai sekolah di kota Medan. Instrumen yang digunakan dalam penelitian ini adalah test tertulis, wawancara dan juga dokumentasi. Teknik analisis data dengan cara penyajian data dalam bentuk hasil perolehan kecepatan waktu pengerjaan siswa serta penarikan kesimpulan. Hasil penelitian menunjukkan bahwa tingkat kecepatan siswa dalam menyelesaikan soal bilangan kuadrat dengan cara konvensional memperoleh rata-rata pengerjaan 40 detik per siswa sedangkan untuk kecepatan penyelesaian jawaban soal dengan cara cepat memperoleh rata-rata kecepatan 25 detik per siswanya dengan jawaban yang sudah dipastikan benar. Kesulitan yang dihadapi sebelum diberikannya konsep cara cepat penyelesaian soal bilangan berpangkat dua: (1) tidak memahami konsep penyelesaian bilangan kuadrat dan (2) kesalahan dalam perhitungan perkalian    &nbsp

TINJAUAN ATAS PENGENAAN PAJAK PENGHASILAN (PPh) PASAL 23 DI PT. INDONESIA POWER PLTU JAWA BARAT 2 PELABUHAN RATU OPERATION AND MAINTENANCE SERVICES UNIT

This Final Project Report was compiled by Aisawa Alama with Student Number 1741211009. With the title REVIEW ON INCOME TAX INCOME (PPH) ARTICLE 23 IN PT. INDONESIA WEST JAVA POWER PLANT 2 PORTS OF OPERATING QUEEN AND ONE MAINTENANCE SERVICE ". compiled based on the guidance of Ms. Reni Anggriani, SE.,Ak.,CA.,M.Ak and Mr. Elan Eriswanto, SE., MM This report is based on the results of research conducted by the author at PT. Indonesia Power Pltu West Java 2 Pelabuhan Ratu. Article 23 Income Tax is a tax that is levied on capital, surrender, services, prizes for awards other than those which have been deducted pph article 21. at PT. Indonesia Power is charged for the services of each transaction made with the vendor. But on the other hand there is still something that needs to be done related to the erroneous tax payment transaction article 23, PT. Indonesia Power as the recipient of the discussion and the recipient of services to borrow and report tax article 23. This study discusses to study and discuss the imposition of article 23 tax on PT. Indonesia Power and find out what types of services are available at PT. Indonesian Strength. In this study, the author uses a descriptive method that can be interpreted as a problem solving procedure that is saved by describing the state of the research subject or object of research (a person, institution, community, etc.) when searching for facts that can be seen, or displayed the results . Data collection techniques used in this report are interviews, observation and library research. Interview is a method of data conversion by way of question and answer. Observation is a technique of collecting data directly to the company. While the literature study the author conducted a literature study to find and collect information through various media such as journals, reference books, trusted internet sites and government regulations. Based on research that has been done, it can conclude the tax imposition of article 23 at PT. Indonesia Power is carried out well in accordance with the taxation procedures performed. PT. Indonesia Power also carries out tax assignments as cutters and collectors carried out properly in accordance with taxation guidelines. And the efforts made for those at PT. Indonesia Power is right, namely by making tax guidelines called tax guideline
