volumes have been published. So many
interesting topics and areas have been
covered in all the articles. EETech News

articles also include participations from
other institutions, not restricted to UiTM.

We hope that the readers may benefit from
the articles and keep supporting EETech
News in the years to come. I would also like
to thank and extend my gratitude to the
management for approving this project and
to my co-editors, as well as the
contributing authors for this issue.

"How to include SDG in
Education?"

"United Nations (UN) has a consensus that was
launched in 2015 and adopted by 193 countries,
Malaysia included. The Sustainable Development
Goals (SDG) listed 17 goals to address the long-
standing challenge faced by the community and
the world. The primary purpose is to end poverty,
protect the planet, and ensure everyone's well-
being by 2030. This is an urgent calling to all
countries (poor, rich, and middle-income
countries) to work together and make sure no
parties are left behind. Putting an end to poverty
and hunger must go in hand with the strategies to
improve health and education and reduce
inequality. Consequently, to spike in economic
growth while fighting climate change and working
to preserve our oceans and forests. " Page 5

SCIENCE OF COOKING: MAILARD REACTION

Have you ever wondered why meat items such as
chicken breast or beef steak become brown after
cooking? In culinary world, this process is known as
the Maillard reaction (pronounced as my-yard), named
after Louis-Camille Maillard, a French chemist who
discovered this process in the early 20th century.
The process of the Millard reaction occurs when the
proteins and sugars in and on the food are heated
(exposure to heat), and a simultaneous chemical
response occurs, giving the food new flavours, scents,
and colours.

The chemical interaction between amino acids and sugars are important elements that contributes to
the Maillard reaction. Importantly, carbohydrates must be present for the Maillard Reaction to take
place. The Maillard reaction is an advanced process which begins with the creation of glycosylamine (a
type of glycoside). Glycosylamine consists of a glycosyl group attached to an amino group. All these
substances undertake a reaction called Amadori rearrangement to produce a derivate of amino deoxy
fructose. The temperature of the Maillard reaction process begins at room temperature, and the cycle
continues when the surface temperature of the food reaches 149°C. The Browning process happens
when a small amount of moisture is needed in the food from a molecular level to aid, although too
much can impair it.

However, there are some ways to remove surface

moisture such as drying the surface of the food with

paper towels before cooking, air drying meat and

vegetables on a tray in the refrigerator overnight, and

salting foods right before cooking to prevent excess

moisture on the surface due to osmosis and before

pan-searing, as well as reverse-searing beef in the

oven dries the food’s surface to quicker browning.

Additionally, the Maillard reaction also takes place at

room temperature but at a much slower rate and occurs

at its slowest at low temperatures, low pH and low Aw

levels. Along with producing colour, the Maillard

reaction also simultaneously produces a vast array of

unique flavours. Methionine and cysteine: two amino

acids that contain sulphur, are crucial in the synthesis of References

The importance of spatial data technology, specifically the use of remotely
sensed data and geographic information systems (GIS), has significantly
emerged in recent years [1]. Remote sensing is the art and science of taking
measurements of the planet from aircraft or satellites using sensors
mounted on the aircraft or satellite.
Sensors which installed on a platform (specifically, satellite, aerial, or
unmanned airborne systems) above the earth's surface measured and
recorded the electromagnetic radiation [2]. The sensors is mounted for a few
hundred meters away above the earth’s surface. Data collection methods
from remote sensing can be in active or passive. Natural radiation emitted
or reflected by the objects under observation is picked up by passive
sensors while Active sensors, like radar, produce their own energy in the
direction of the object, and then measure the signal that is reflected back
from the object [2].
Remote sensing offers a remarkable amount of geographical data and
information in this method. This provides a practical method for monitoring
and detecting changes to the environment and the earth. As a result, it is a
significant tool in both basic and applied sciences, especially in the fields of
geography, geoscience, and the environment [2].

Satellites are important for the advancement of technologies like global
mapping, GPS, and urban planning. The collection of geographical data is
one of the many breakthroughs made possible by satellites in orbit.
Agriculture, weather, forestry, biodiversity, and a number of other sectors
and industries are all key users of remote sensing. In the field of coastal
engineering, remote sensing can be used to determine sea surface
temperature, chlorophyll content, suspended sediment concentration, yellow
material concentration, wave characteristics, and many more coastal
element. Remote sensing imagery is linked into a geographic information
system (GIS).

The Geographic Information System (GIS) is a tool for creating and
analyzing spatial data which spatially referenced to the earth, and it is
primarily concerned with the position of features as well as their properties
and attributes. It assists researchers in gathering, analyzing, and visualizing
geographic data for a variety of reasons [3]. The study of remotely sensed
data and recent technical advancements in geographic information system
(GIS) techniques and approaches have shown to be effective tools in both
fundamental and applied geosciences [2].

CONFIGURING MY OWN HOME

MODEM: HINTS AND TECHNIQUES

Written by Wan Ahmad Khusairi bin Wan Chek
(School of Electrical Engineering , College of Engineering
UiTM Terengganu Branch Dungun Campus

Ever wonder how to configure your own modem at Figure 1
home? After discovering warning signals from my old,
original Unifi modem, I decided to install a new modem
with Huawei Wifi AX3 modem that I bought from
Shopee. For configuring the modem, an IP address of
192.168.3.1 has been set up. For the changes to take
effect, the modem must be turned ON during the
configuration process
To set the settings for boxes 1,2, and 3 in Figure 1, I have
contacted the Unifi support Centre to receive the
necessary information. As shown, the MRU and MAC
clone are configured as default since they will not cause
any internet disconnection. In order to enable home Wi-
Fi accessibility inside the house, VLAN configuration has
been set up to “Malaysia Unifi”. After all the setting
completed, the Wi-Fi connection is established.
.

The next step is to configure and connect my television
using my HppTV box in order to enable the Wi-Fi
network. The configuration is part of the IPTV
configuration depicted in Figure 2. Prior to enabling the
IPTV network, the LAN interface to LAN3 has been set
up since the HyppTV box is connected to LAN3 on the
HUAWEI modem. Once again, the IPTV setup requires
the mode selection of “Malaysia Unifi” before the
HyppTV box can be connected to the internet via the
modem. As soon as the setup completed, the HyppTV
box resumed its normal operation.

The hype of JWST does not stop there as later, more images were released such as Stephan’s Quintet,
Southern Ring Nebula, WASP-96b and SMACS 0723 [1]. The latest reveal was the Tarantula Nebula. It was
not an unknown nebula but rather a familiar one that was viewed by a new set of eyes. The nebula was
nicknamed as such due to its resemblance to spider but with recent development, the JWST shows that the
appearance is more of a resemblance to a burrow lined with tarantula’s silk [3]. Most of the images released
was a revisit of the old images captured by Hubble Space Telescope and comparison of the images
captured by each telescope was widely shared through social media and mainstream news alike.

The comparison astonishes us even further as the clearer images captured by the JWST shows the existence
of a multiple galaxies in the background that was not evidence through the Hubble Space Telescope. The
JWST operate differently from the Hubble as the Hubble mainly observed in optical and ultraviolet
wavelengths with minor infrared capabilities, while the JWST primarily observed in infrared and due to the
nature of space that made JWST capable to observed in great detail using infrared telescope. Another major
difference is that the JWST orbit the sun whilst the Hubble Space Telescope only orbit the Earth [5].

The reveal gave a glimpse of celestial body to be discovered in our solar system and inspire new generation
toward space discovery and cosmic study. Hopefully this progress be a springboard to new technological
invention that gives benefits to humankind. As of now, the world will patiently wait and wonder at every
image released by JWST.
