Based on the result of the analysis it was then synthesized a new signal to comprehend whether the analysis results were appropriate or not .
The research was conducted by recording the sound of the gong by using Sound Forge software. The data of recording result were analyzed using FFT in order to obtain the sound signal components. The process of sound synthesis was conducted by using additive synthesis method supported by Matlab (R2012a) sofware.
The results of this study showed that there were some basic factors which determined sound signal, which were fundamental frequency, harmonic frequencies, amplitudes, amplitude ratios and phase differences. The sound signal as the result of reconstruction from the data had been close enough to natural sound produced by the gong.
The results of this study showed that the phenomenon of "ngombak" on the gong ageng was a beat between two frequencies that have a relatively high amplitude. Beside that, this study also showed that there were some fundamental factors that made up a sound signal that were the fundamental frequency, harmonic frequencies, amplitudes, amplitude ratios and phase differences. The sound signal reconstructed from the data above was good enough to approach the natural sound generated by the gong.Fauji AhmadPurwanto Agus2014-11-07T04:28:30Z2014-11-07T04:28:30Zhttp://eprints.uny.ac.id/id/eprint/11480This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/114802014-11-07T04:28:30ZTHE COMPARATION STUDY OF LABORATORY EXPERIMENT AND

COGNITIVE ACHIEVEMENT AND SCIENCE PROCESS SKILLS ON THE
TOPIC OF LINEAR MOTIONThis research aims to compare the effectiveness of laboratory experiment and computer
simulation methods in the teaching-learning of physics. It can done by testting the difference of cognitive
achievement and science process skills for students who learn physics, on the topic of linear motion, by
using laboratory experiment and computer simulation methods. This topic includes motions along a
straight line with a constant velocity and a constant acceleration.
The research method was a quasi-experiment with pretest-posttest experimental group design. It
was conducted in SMAN 2 Wates. The population was all students in this school and the sample was the
X-grade students. The sampling technique was the cluster random sampling. After drawing lots, the X-Agrade student was the experiment group using simulation and the X-C-grade student was the experiment
group using experiment laboratory. Data were collected by using pretest and posttest, based on students’
cognitive achievement and science process skills. Data analysis method to test hypothesis was Manova
(Multivariate Analysis of Variance). Before hypothesis testing, the pre-requisite analysis was done, that is
the normality of data distribution and variance homogeneity.
This research shows that (1) there were the increasing differences of cognitive achievement and
science process skills between students who learn physics on the topic of linear motion by using
laboratory experiment and computer simulation methods; (2) the laboratory experiment method was more
effective than the computer simulation.Sumardi YosaphatKhasanah DyahUtami TitinIstikhomah Novia2014-11-07T04:28:29Z2014-11-07T04:28:29Zhttp://eprints.uny.ac.id/id/eprint/11477This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/114772014-11-07T04:28:29ZIMPROVING THE RESULT OF PHYSICS STUDY OF THE STUDENTS

CONCEPTS THROUGH COMPUTER SIMULATION ANIMATIONThe use of computer simulated animation as learning media in Physics has gained
popularity. This research aims to test the student’s self-confidence to understanding and
the student’s belief in the concepts of Physics presented by computer simulated
animation. The study was conducted by means of in-depth interviews to one student on
the physics concepts that were being studied through a computer simulated animation.
The interview results show that the student does not believe in the accuracy of concepts
presented by the animation. The student still doubt the accuracy of the physic concepts
that have already understood and the concepts presented thorugh the animation after
answering series of questions testing the accuracy of ith concepts. This research
recommendation is that there should be teachers’ guidance to help students learning
through computer simulated animation to understand physic concepts .Hari Kristiyanto WahyuPrabowo PrabowoKardi Soeparman2014-11-07T04:28:29Z2014-11-07T04:28:29Zhttp://eprints.uny.ac.id/id/eprint/11488This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/114882014-11-07T04:28:29ZANALYZING PHYSICS ITEMS OF UN, TIMSS, AND PISA

PISA are higher in the aspect of contextual, complexity, and reality in the daily life
than the others.Wasis Wasis2014-11-07T04:28:29Z2014-11-07T04:28:29Zhttp://eprints.uny.ac.id/id/eprint/11523This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/115232014-11-07T04:28:29ZTHE DEVELOPMENT OF UNIVERSAL MASS BALANCEIn this paper, we describe the construction of the Universal Mass Balance (UMB).
The working principle of UMB has been tested through parabolic flight in
microgravity, normal gravity and hypergravity environment to investigate the
independency of measured oscillation frequency to the oscillated mass on
gravitational conditions. The frequency was obtained by analyzing the emf signal.
Later, the UMB was simplified by using optical detection. Once the UMB is
calibrated, the unknown mass can be measured by slightly displacing it from
equilibrium position to oscillate. As the frequency is known, the mass of the load
immediately can be calculated automatically and displayed. The UMB offers
potential applications in space science related fieldAziz Wan Nor Suhaila WanAyop Shahrul KadriAmat Mohamad AzrulHashim Mohd HelmyJaafar Rosly2014-11-07T04:28:28Z2014-11-07T04:28:28Zhttp://eprints.uny.ac.id/id/eprint/11520This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/115202014-11-07T04:28:28ZRE-EVALUATION OF HILAAL VISIBILITY CRITERIA

TRAPPED PARTICLEMicrorheology studies are based on Brownian motion (BM) of particles. The main
causes of BM are thermal fluctuation and viscosity of medium. One of the
microrheological methods is single probe study using Optical Tweezers (OT) to
extract information about the material characteristics. The OT uses single particle,
which undergoes BM. For analysis of the BM, we need Power Spectrum Density
(PSD). Therefore, this paper discuss on the simulation of the PSD calculation of
single particle in liquid. We generate random number, which represent the
displacement of the particle for on allocated period of time. The PSD is calculated
using Origin Pro 9.1. The resulted PSD is useful for further investigations, for
example in characterization of storage and loss modulus of a material.Riyanto SugengAyop Shahrul KadriAziz Wan Nor Suhaila Wan2014-11-07T04:28:25Z2014-11-07T04:28:25Zhttp://eprints.uny.ac.id/id/eprint/11495This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/114952014-11-07T04:28:25ZDEVELOPMENT OF EVALUATION MODEL OF PHYSICS EXPERIMENT
EXAM FOR SECONDARY LEVELSurvey on using of science laboratory and physics experiment as particular showed schools
generally almost never use experiment methods in learning process, some schools performed once until
fourth in a 6month-period. Even they applied experiment method, schools tends to use cook-book type of
students worksheet with less to equip student’s thinking skills, lack of investigating experiment guidance
and its rubrics given by government. The research is aimed to develop evaluation model of physics
experiment exam for secondary level. Two types of experiment guidance and its evaluation rubrics are
developed; type A focused on abilities to plan experiment activities, while type B is related with abilities
to conduct the planned experiment. The research was carried in 3 secondary schools at low-medium-high
students’ categories to gain various feedbacks. The research, which covering 6 physical science (linear
motion, change of matters, density, waves, expansion, and electricity), produced revised experiment
guidance based on qualitative analysis of students’ responses in performed A and B types, respectively.
Some strike points has been made to revise the experiments guidance A type such as describing problems,
predicting, determine materials, experiment procedures ideas to solve problems. Furthermore, in type B
the emphasize lies on data quality, analyzing and inferring aspects. The result of the research is a
fundamental research to develop scaling up of evaluation model of physical science.Utari SetiyaImansyah HarunLiliawati WinnyHidayat Arif2014-11-07T04:28:25Z2014-11-07T04:28:25Zhttp://eprints.uny.ac.id/id/eprint/11507This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/115072014-11-07T04:28:25ZTHE PATTERNS OFTHE SOUND INTENSITY DISTRIBUTION OF
MIDRANGE LOUDSPEAKERThis study aimed to determine the pattern of intensity vector distribution of the midrange loudspeaker at frequency 3000 Hz and 6000 Hz. The 3000 Hz was selected because human ear was very sensitive to this frequency, whereas the frequency 6000 Hz was selected as an output limit of the midrange loudspeaker. The data were collected by using two condenser microphone that was connected by using a Spectra Plus 5.0 program to the computer. The data (voice) were taken at a distance of 1 meter from the center of the loudspeaker. The distance between the sample points was 10° for one position and there were 36 points for each frequency. At each sample point on a position, a second condenser microphones rotated by 36 points around the first condenser microphone. The second condenser microphones rotation interval was 10. At frequency 3000 Hz, the pattern of sound intensity vector distribution tended to spread over the front and the left side of loudspeaker. While at frequency 6000 Hz, the pattern of sound intensity vector distribution focused to the front of loudspeaker.Laely Septiana NurPurwanto Agus2014-11-07T04:28:24Z2014-11-07T04:28:24Zhttp://eprints.uny.ac.id/id/eprint/11503This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/115032014-11-07T04:28:24ZTHE DEVELOPMENT OF TITANIA SOLAR CELLS BY INSERTION OF CONDUCTIVE MATERIAL AS AN ALTERNATIVE THIRD GENERATION SOLAR CELLSSolar cells are one source of electrical energy alternatives being developed. One of them is a third-generation solar cells are made from titania. Titania serves as the active layer in photoelectrochemical solar cells. Various modifications to the titania layer is done to obtain the efficiency of solar cells better. Modifications can be done by inserting a conductive material on titania layer. Conductive material which inserted can be either metallic copper (Cu) or iron (Fe). Insertion of metal copper or iron in the active layer of titania aims to accelerate the movement of electrons results in the generation of titania coating, onto the electrodes. So the current become higher and we get the efficiency of solar cells better.Prasetyowati Rita2014-11-07T04:28:21Z2014-11-07T04:28:21Zhttp://eprints.uny.ac.id/id/eprint/11482This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/114822014-11-07T04:28:21ZPERFORMANCE OF DIPLOMA OF SCIENCE STUDENTS AT UPSI IN

need to the PBL-based physics module for the gifted-talented students and defining the developed
teaching materials. The results of the definition of the curriculum a nd students’ characteristics are used to
develop the module for the gifted-talented students adapted with PBL syntax. Review and validation were
conducted in three phases. The first phase was done by linguists and graphics and material experts, the
second phase by a Physics lecturer who also assessed other research instruments, and the third by their
peers (Physics teachers in accelerated classes) in order to make the final module ready to be tested to the
students. A post test-only control study design was employed to test the use of the module. The results
showed that the module was appropriate for use with good criteria (assessment of experts is at 3.22;
assessment of lecturers at 3.45; assessment of teachers at 3.61 with a maximum scale of 4). Students'
response to the module was very positive. Students were vastly interested in the use of the PBL-based
Physics module and found it easy to use. Based on the statistical tests, the results showed that students
with this module had learning achievements of cognitive, affective, and psychomotor better than those
who merely used the school-book in the PBL learning environment. This indicates that the PBL -based
Physics module can effectively be used to improve the learning achievements of cognitive, affective, and
psychomotor of the students.Niswati Rodliyatul Jauhariyah MukhayyarotinSarwanto SarwantoSuparmi Suparmi2014-11-07T04:28:19Z2014-11-07T04:28:19Zhttp://eprints.uny.ac.id/id/eprint/11543This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/115432014-11-07T04:28:19ZTHE EFFECT OF REDUCING Na2O AND INCREASING PbO ON OPTICAL AND PHYSICAL PROPERTIES OF TZPBN:Er GLASSESThe TZPBN:Er [55TeO2 – 35ZnO – (5+x)PbO – 2Bi2O3 – (2-x)Na2O – Er2O3] glasses where x = 0, 0.5, 1, 1.5, and 2 % mol have been prepared by melt quenching technique. The physical colour of glasses are pinky because of Erbium Oxide doped. But, the pink colour decreased with increasingly Pb2+ ion. Beside that, the transparency of glasses decreased with reducing Na2O as a modifier ion in glass composition. The density measurement were made by Archimedes method used pycnometer and calculated with empirical equation. The refractive index of glass measured with spectrometer by Brewsters’ angle method. Increasing of PbO in TZPBN:Er composition have density effect and refractive index effect. The density and refractive index of glass increased with increasing Pb2+ ion on each composition of glasses.Jauhariyah Mukhayyarotin Niswati RodliyatulMarzuki AhmadCari Cari2014-11-07T04:28:18Z2014-11-07T04:28:18Zhttp://eprints.uny.ac.id/id/eprint/11489This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/114892014-11-07T04:28:18ZIMPROVING THE STUDENT LEARNING OUTCOMES

This research was started with a recorded sound of an acoustic guitar in the key of C with the plucked technique. The research samples were recorded by using the software of SpectraPLUS 5.0. From the data it was taken samples of 5 periods. Then the data were analyzed using Matlab R2010 to obtain the spectrum in every sound signal. The sample was correlated by using Microsoft Office Excel 2013. The correlation result was then presented in a correlation graphics with the x-axis as a number of shift and y-axis as a correlation value. The correlation result showed harmony pattern on each triad in the scale of C major. Content of the signal spectra, showed frequencies and amplitudes. The higher the number of similar frequency content of the two notes in a triad, the more comfortable the two notes were listened to. Amplitude in each harmonics affected the correlation value. The higher the amplitude the greater the correlation value. The lower the amplitude the smaller the correlation value. The number of data of cutted signal also affected the precision of position of the maximum of cross-correlation between two notes in a triad. The correlation concept can be used to prove the level of similarity between two signals in a triad.Rusitha MegaPurwanto Agus2014-11-07T04:28:15Z2014-11-07T04:28:15Zhttp://eprints.uny.ac.id/id/eprint/11538This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/115382014-11-07T04:28:15Z“JOKO TINGKIR” FOR DECISION MAKING ON REALTIME TSUNAMI WARNING SYSTEMMost of Tsunami Early Warning System has used earthquake magnitude as indicator of tsunami.

Purpose of this study is to test the validity of Joko Tingkir computer program for decision-making on a tsunami early warning system in real time. The Joko Tingkir computer program implemented a Tsunami Faulting Model (TFM). TFM uses the principle that the tsunami affected by the length and width of earthquake rupture. Both can be represented by the duration of rupture (Tdur) or Exceed 50 second duration (T50Ex) and the dominant period (Td). TFM has been implemented by Joko Tingkir computer program. Based on the test results of Joko Tingkir computer programs in real time for 146 earthquakes (magnitude 5 to 6.9) and offline testing at FMIPA UNESA laboratory for 33 earthquakes (magnitude 6.5 to 9.3) can be concluded that the Joko Tingkir computer program can estimate Tdur, T50Ex and Td simultaneously, accurately and quickly, so the Joko Tingkir computer program can be used for decision making on real time Tsunami Early Warning System.Madlazim MadlazimSupriyono SupriyonoMasturyono MasturyonoHardy ThomasKaryono Karyono2014-11-07T04:28:13Z2014-11-07T04:28:13Zhttp://eprints.uny.ac.id/id/eprint/11491This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/114912014-11-07T04:28:13ZTHE MEASUREMENT OF LECTURERS’ TEACHING QUALITY AND

Hitherto a mathematical model that predicts the hilal visibility for a particular location only consider Moon–Sun geometry configuration and twilight sky brightness factors. This paper discusses hilal visibility predictions on telescopic–based visual observations which include the age of the observer, the light transmission in the optical instrument, the size of the mirror/lens as light collector and the magnification of the telescope used as well. The model accommodates all of the above factors are then applied to predict the next hilal visibility for the beginning of Ramadan, Shawwal and Dul-hijjah 1435 Hijri (2014 AD).Utama Judhistira Aria2014-11-07T04:28:01Z2014-11-07T04:28:01Zhttp://eprints.uny.ac.id/id/eprint/11528This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/115282014-11-07T04:28:01ZTESTING MICROCRYSTALLINE CELULLOSE USING SPECTROMETER AND POLARIZED LIGHT MICROSCOPEIt has been proposed to test the microcrystalline of cellulose materials using polarized light microscope (PLM) and uv-visible spectrometer . The microcrystalline cellulose was prepared from kenaf bast fibers while the nano crystalline was prepared from alpha cellulose using thermal acid hydrolysis. We use at 20% (v/v) and 40% (v/v)H2 SO4 in the experiment mixed and stirred within an hour up to hours. The testing using PLM clearly indicates the existence of microcryatalline cellulose while the use of uv-visible spectrometer can reveal the effectiveness of the acid hydrolysis in extracting the nanofibril from the alpha cellulose.Harsojo HarsojoMardiansyah DediSosiati Harini2014-11-07T04:27:59Z2014-11-07T04:27:59Zhttp://eprints.uny.ac.id/id/eprint/11493This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/114932014-11-07T04:27:59ZINCREASING STUDENT’S ATTENTION IN PHYSICS LEARNING WITH

INSTRUCTION-ASSISTEDThis study examines the increasing attention of student in learning using three variations of Physics
Assisted Learning Interactive Computer Program (PFBPKI) as Self Operated Instrument (SOI) , and
PFBPKI as a medium, as well as learning without PFBPKI on three superior class-1, class-2 and regular
class, through a quasi- experimental study factorial. The attention significantly increased from the three
variations of learning , the three classes of treatment [F (2, 253 ) = 183.92 , p < 0.05] with the effect size
of 59%, the difference class in attention was significant [F (2,253 ) = 8.39, p < 0.05] with effect size by 6
%, while the effect of the interaction between learning with classroom variation was also significant [F
(2,253 ) = 8.39, p < 0.05] with effect size by 7 %. The analysis showed increased interest in learning
variations contribution is much larger than the class differences and interactions. So the authors
speculation that attention affects the learning process empirical can be proved. This study found the junior
high school students are more interested in studying physics with PFBPKI operated by their selves, and
giving much attention to the relatively high contribution to the regular classes, its mean that computer assisted learning contribute to increase the learning attention of all junior high school students.Festiyed Festiyed2014-11-07T04:27:53Z2014-11-07T04:27:55Zhttp://eprints.uny.ac.id/id/eprint/11529This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/115292014-11-07T04:27:53ZMODELING OF REACTIVE MAGNETRON SPUTTERING IN TIALN FILM DEPOSITION: ANALYSIS OF PUMPSPEED AND TARGET CURRENT EFFECTA model of reactive magnetron sputtering has been developed by using mathematic model.

Computation and radiotherapy simulations are done on model of thyroid cancer. Tumor tissue is at a depth of 11.2 mm and has a thickness of 14 mm covered by three normal tissue, i.e. skin with a thickness of 1.2 mm, adipose tissue with a thickness of 4 mm and muscle tissue with thickness of 6 mm. The thyroid tissue is irradiated with 19 proton beams with energies ranging from 36 MeV to 54 MeV to cover the entire area of the tumor and will produce 19 Bragg curve. Computation is done to obtain appropriate weighting factors for each of the Bragg curve which then can be used to determine the number of protons for each beam in order to obtain the desired ionization effect.Sulistya EkoKusminarto KusminartoHermanto Arief2014-11-07T04:27:50Z2014-11-07T04:27:50Zhttp://eprints.uny.ac.id/id/eprint/11504This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/115042014-11-07T04:27:50ZPOWER SPECTRUM OF LARGE GONG (GONG AGENG) KAGUNGAN
DALEM GONGSO KANJENG KYAI GUNTUR SARIThe purposes of this research were to observe the power spectrum and the evolution pattern of the power spectrum of large gong (gong ageng) Kagungan Dalem Gongso Kanjeng Kyai Guntur Sari. Power spectrum was important because physical quantities involved an energy transfer which had a close relationship with acoustic energy detection in the hearing process.
The data in this research were secondary. The source of sound signal was a set of large gong (gong ageng) which consist of gong ageng 1 and gong ageng 2, while the sensor to detect the sound signal was condenser microphone. As soon as the instruments were played, the condenser microphone was put in the resonance box (behind of gong) in order to record the signal from the first time they played until the amplitude was decayed.
The result of the power spectrum analysis using Parseval’s theorem which was implemented in own made program by Matlab (R2010a) showed that, in the large gong (gong ageng) instrument, the biggest sound power was owned by the second harmonic component which is 88,2 Hz. The analysis result of the power evolution of large gong (gong ageng) showed that all frequency components had regular evolution pattern as well as regular interval which resulted in wave (ombak) phenomenon.Nurani DharaPurwanto AgusSumarna Sumarna2014-11-07T04:27:49Z2014-11-07T04:27:49Zhttp://eprints.uny.ac.id/id/eprint/11532This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/115322014-11-07T04:27:49ZAN EXAMPLE OF SYSTEM WHICH CAN BE USED TO EXPLICITLY SHOW THE SYMMETRY BETWEEN THE ELECTRIC AND MAGNETIC FIELDSElectric and magnetic fields are almost but not exactly symmetric. That fact does not preclude the existence of perfect symmetry in specific systems in a certain context. In this paper we describe an example of such systems which are charge distributions with cylindrical symmetry and their related systems of current distributions with cylindrical symmetry (which of course can be realized by moving the first systems with constant velocity longitudinally along the cylindrical length). We will show that in these systems there is perfect symmetry and we will prove that the symmetry can be understood from the standpoint of special relativity.Hermanto Arief2014-11-07T04:27:49Z2014-11-07T04:27:49Zhttp://eprints.uny.ac.id/id/eprint/11534This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/115342014-11-07T04:27:49ZTHE EFFECT OF TELLURIUM ATOMIC FRACTION ON THE CRYSTAL

TECHNIQUEThis study aimed to determine the effect of atomic fraction x of tellurium (Te) on the lattice parameters
and the crystal structure of the Pb (Se, Te) compound prepared using Bridgman technique. Further
characterization of the materials used X-Ray Difraction to determine the lattice parameters and the crystal
structure. The chemical composition was determined using Energy Dispersive Spectroscopy (EDS), and
the surface morfology shown by Scanning Electron Microscope (SEM). The results showed that all
compounds crystallized in a cubic crystal structure and the lattice parameters of the crystal were a
function of the fraction x of Tellurium atoms. EDS results showed that all samples were non
stoichiometric but approached ideal composition. All compounds had identical surface because it had a
cubic structure with homogeneous materials.Ariswan AriswanDarmawan Denny2014-11-06T08:55:12Z2014-11-06T08:55:12Zhttp://eprints.uny.ac.id/id/eprint/11458This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/114582014-11-06T08:55:12ZDEVELOPMENT OF BLENDED LEARNING MODEL FOR IMPROVING
STUDENTS COMPETENCE IN THE ENGINEERING PHYSICS LEARNINGEngineering Physics at the Faculty of Engineering, State University of Padang is supporting courses for
expertise courses. The courses material of Engineering Physics is adapted to the needs of expertise
courses in every department. The fact showed that the ability of students to master the concepts of physics
is still low. Thus, they face difficulty in applying physics concepts to the relevant expertise courses.
Therefore, the students are demanded more to be active and the lecturers are applying a variety of
learning methods. The obstacles, face to face time in the classroom to be insufficient to meet these
demands. One of learning model that can be applied is a blended learning model. This research aimed to
develop a model of blended learning to improve student competencies in engineering physics learning.
Research and development of research methods were refer to Borg and Gall models with four stages: a
preliminary study, planning, development, and implementation. The development model of learning is
done by combining face-to-face learning with a web-based learning (e-learning), so that students have the
competence to master and apply the concepts of physics. E-learning programs are developed to support
blended learning using e-learning software from Moodle, because it has a complete facility needed. The
results showed that the developed learning model was valid, practical, and effective to improve the
competence of physics and applied the physics concepts.Usmeldi Usmeldi2014-11-06T08:54:59Z2014-11-06T08:54:59Zhttp://eprints.uny.ac.id/id/eprint/11461This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/114612014-11-06T08:54:59ZTREATING FOURIER SERIES AS VECTOR:
A CONCEPT SIMPLIFICATION FOR TEACHING FOURIER SERIESFourier series as a representation of periodic function is quite frequently
encountered in various fields of science and engineering, especially in physics. In
practice, even non-periodic function defined in a certain range of the domain can be
represented by Fourier series. Vectors, on the other hand, are usually introduced
earlier than Fourier series. Similar to Fourier series, vectors are also used intensively
and extensively in physics. In this paper we will examine the properties of Fourier
series that account for its similarities to the properties of vectors. The orthogonal
properties of bases vectors in the context of dot product amongst bases vectors will
be the central discussion to examine the similarities between vectors and Fourier
series.V.D. Wirjawan Johannes2014-11-06T08:54:59Z2014-11-06T08:54:59Zhttp://eprints.uny.ac.id/id/eprint/11462This item is in the repository with the URL: http://eprints.uny.ac.id/id/eprint/114622014-11-06T08:54:59ZMAPPING OF PROFESSIONAL, PEDAGOGICAL, SOCIAL, AND PERSONAL
