Abstract
By analysing both theoretical and experimental aspects of the Torricelli's Law,
we develop a questionnaire that specifically used to detect the misconceptions
occurred in this subject. All responses from the questionnaire are analysed
carefully to find out significant causes related to each point of misconceptions.
The findings suggest us how to improve our teaching in Fluid Mechanics.
The experiment with variety of orifice sizes also suggests us how to choose the
appropriate one which is useful for designing the experimental kits for students
at different education levels.

Abstract
The home-made apparatus for determining fluid viscosity is invented during the
COVID-19 pandemic. Our notion is based on the use of underwater variable length
pendulum. The certain string length where critical damping of the pendulum
starts to occur can be found with the bare eye and thus allows us to calculate the
viscosity of our designed fluid. Unlike other apparatus whose viscosity determination
technique requires stopwatch or other electrical instruments, our apparatus is
purely mechanical.

Abstract
Among several techniques to observe terminal velocity that require sensors
technology or high frame rate VDO recording, we propose a simple low-cost
technique anyone can do at home, just a bottle of designed liquid supported by a
mass scale and a suitable spherical object are required. Our notion is based on the
Newton's third law applying between sphere-liquid, liquid-container and container-
mass scales. As a consequence, buoyancy and drag forces can be detected on the
mass scales and the reading will be increased in the same way as the velocity
does. Based on this experiment, we also develop a questionnaire used to detect
the misconceptions about buoyancy force, drag force, and Newton's third law.
The results obtained from this questionnaire are important for the development
of science curriculum and instruction in the future.

Abstract
In a normal classroom, finding the basic values from the experiments in the story
of the Coupled Pendulum that requires knowledge of the initial period and
frequency determination. Applying the matter of Oscillation motion to explain,
for example, a pendulum clock. which is a pendulum swing to figure out the
equation of elimination leading to periods and frequencies but different objects
are connected together and observed the change. The frequency and period of the
Coupled Pendulum is generally determined by measuring the distance of one full
cycle of motion and taking note of the time value to determine the period. The
method obtained is quite difficult because the distance measurements happen
quickly and easy errors. Difficult to repeat experiments, therefore designing
various methods. For convenience, variety and accuracy through the use of the
Tracker program that measures distances and angles that change with time Using
a variety of applications, and another method is to use a variety of applications
that use magnetic field sensors. from the need to create equipment to use in the
laboratory starting from the center because the company that sells the ready-made
kit doesn't say what's inside. Therefore, it must be built from learning theory
figuring out how to measure and compare the values obtained.

Abstract
The stroke is a serious, life-threatening problems because it has no warning. This
can bring dramatic and unexpected changes in human’s lives. The rapid detection
of brain damage is the best way for preventing the risk of stroke patient life.
Therefore, this research aims to fabricate the finger force sensors to measure the
magnitude of finger force in daily life. The thin film force sensors were applied
on the finger exercise equipment. This equipment could adjust the spring constant
which use to create the restoring force. Then, the fingers were pushed with the
various spring constants so that the force was varied. The force from the 4 fingers
were also collected by Arduino program. The results show that the sexual and
finger length could affect the force of the fingers. We found that males could exert
force on the sensors more than females. In addition, the middle finger is stronger
than the others. The results indicate that humans have different hand
compressions due to the different forces of the fingers. Moreover, our sensor
could be applied to record the data of the finger exercise; these data can be used
to compare with everyday life data for indicating and predicting the risk of stroke.

Abstract
In this project, we develop a Boyle’s law experiment, which is one of the General
Physics laboratories, into an online system using the ESP8266 node
microcontroller units (Node MCU) and Internet of Things (IoT). Generally, the
Boyle’s law experiment consisted of two moveable glass tubes that contain
mercury (Hg). One end of the glass tubes is opened while the other is closed.
Stepping motors, which were connected to the Node MCU, have been attached to
move glass tubes instead of a conventional method. The level of Hg was observed
by a webcam connected to the Node MCU. The Node MCU was wirelessly
connected to the smartphone via the web application. The results of our Boyle’s
law experiment agree with the conventional setup. In the future, our system will
be developed into a web application that can be run anywhere that there is the
internet.

Abstract
Harmonograph is a fascinating device that can create patterns. The patterns are
created on paper by the movement part of the harmonograph. The oscillatory part
of the harmonograph is the central mechanism caused by the pendulum. A
harmonic graph of simple harmonic motion from a harmonograph is used to
instruct media instead of a pendulum or spring by studying the Lissajous figures.
This research presents the application for examination of the Harmonograph
behavior. Users can use the program to examine the image affected by oscillated
components of the harmonograph. In this research, applications consist of the
following. Frist program can simulate the images obtained from a harmonograph.
The second program is to find the parameters of the equation of motion of the
pendulum on both axes. The third program is a program to simulate the movement
of the harmonograph. From the study, the image characteristics of the
harmonograph obtained from the application have a related appearance to the
Lissajous diagram by will look distorted from the Lissajous if the arm length of
both sides is short. The resulting distortion is proportional to the arm length and
the distant from the pivot point to the vertex point of the pendulum.

Abstract
In 2019, the education was interrupted by COVID-19. The students could not go
to study in the classroom. They lost the opportunity to learn practically. Therefore,
this research aims to prepare the virtual experimental which using Arduino Wi-
Fi board for controlling the equipment in real-time. The reflection and refraction
of light were selected for setting this virtual lab because the students can learn
visually and they could understand the Snell’s law from this experiment in one
shot. The experiment was separated into two parts. The first part is hardware
which consists of NodeMCU ESP8266, servo motor, semicircle acrylic, 360-
degree plate and 520 nm wavelength laser. The second part is the software which
use to adjust and capture the image of reflection and refraction of the light. Then,
the experimental was aligned. The laser must incident on the interface of
semicircle acrylic at 0 degree angle (i.e., orthogonal to the interface). The incident
angles were adjusted from 0 to 90 degrees by Blynk software. The results show
that as the light incident on the surface of the media, the reflection of light at the
interface was occurred. We found that the reflection angle was equal to the
incident angle. Moreover, the refraction of light from the image could help to
determine the refractive index of the acrylic which is equal to 1.54. This research
succeeded to show the virtual lab in which we can control the incident angle of
light by smartphone through the Blynk software. In summary, this virtual lab
could demonstrate the principle of reflection and refraction of light: i.e.,
validating Snell's law, describing the intensity of the reflected and refracted rays
and determining the refractive index of our semicircle acrylic.

Abstract
This project was to study of the energy band gaps of titanium dioxide (TiO2)
nanotubes coated and uncoated with gold nanoparticles. The TiO2 nanotubes were
synthesized by anodizing process in ethylene glycol and ammonium fluoride
electrolytes at room temperature with 25 volts for 90 min. The morphological,
surface composition and crystalline characteristics of uncoated and coated
titanium dioxide nanotubes with gold nanoparticles were analyzed by field
emission scanning electron microscopy (FE-SEM), energy dispersive X-ray
analysis (EDS) and X-ray diffractometer (XRD), respectively. The FE-SEM
results revealed the presence of gold nanoparticles on TiO2 nanotubes. When
coated with 100 cycles and 125 cycles of gold nanoparticles, the TiO2 nanotubes
had a mean diameter of 75 nm and 10 nm of gold nanoparticles, respectively. The
energy band gaps of coated and uncoated TiO2 nanotubes were calculated via
UV-Vis spectroscopy using Tauc plots and Kubelka–Munk function. These
results confirm that the energy band gaps of TiO2 nanotubes were reduced when
coated with gold nanoparticles.

Abstract
This research examines the wetting properties of titanium dioxide nanotubes
coated with gold nanoparticles. The titanium dioxide nanotubes were synthesized
by an anodizing process at room temperature. A voltage difference of 25 volts
was applied for 90 min with ethylene glycol and ammonium fluoride electrolytes.
Titanium dioxide nanotubes were coated with gold nanoparticles by an interval
electroplating technique. The samples were analyzed by x-ray diffractometer
(xrd), field emission scanning electron microscopy (fe-sem) and energy
dispersive x-ray analysis (edx) to explore crystal structure, morphology and
composition, respectively. It was found that the synthesized titanium dioxide
nanotubes have anatase and rutile phases. The morphology clearly shows an
orderly arrangement of tubular tubes When coating titanium dioxide nanotubes
with gold nanoparticles at 100 and 125 cycles, it was found that an increase in the
number of coating cycles resulted in a decrease in the content of the gold
nanoparticles. Contact Angle Meter was used to examine the wettability. The
results show hydrophilic properties of both coated and uncoated titanium dioxide
nanotubes. Titanium dioxide nanotubes uncoated with gold nanoparticles have
contact angles of 39.02 degrees. Titanium dioxide nanotubes coated with gold
nanoparticles for 125 and 100 cycles have contact angles of 38.66 and 74.14
degrees, respectively.

Abstract
The purposes of this research were to 1) develop the lesson plans on matter in
daily life by using problem-based learning with questioning techniques for 5th
grade students, 2) study the learning outcome by using a problem-based learning
with questioning techniques on matter in daily life, and 3) study the problem-
solving ability by using problem-based learning with questioning techniques on
matter in daily life. The sample group was one classroom of 5th grade students
( N=20) selected by cluster random sampling. The research tools consisted of
1) the lesson plans on matter in daily life by using problem-based learning with
questioning techniques, 2) the learning achievement test on matter in daily life,
3) the problem-solving ability test, 4) the item objective consistency assessment
form, and 5) the lesson plan quality assessment form. The results showed that
1 ) the quality of the lesson plans was at high level ( X̅ = 4 . 4 3 , S.D. = 0 . 5 3 ) ,
2) the mean scores of students’ learning on matter in daily life were higher than
70 percent criteria at statistically significant .05 level, and 3) the mean scores of
students’ problem-solving ability on matter in daily life were higher than 7 0
percent criteria at statistically significant .05 level.
