Sehari di Karnival Sains Daerah Gombak 2011


Pada 20 April 2011, SEPINTAR  telah menghantar  5 orang pelajar iaitu ;


1. Mohammad Firdaus bin Ahmad 
2Amin Khalidi bin Alias
3. Amirul Shauqi bin Abdul Razak
4.Nurulain bin Shahrul Bahri
5.Noor Naimah binti Mahmud

Pelajar-pelajar di atas adalah sebahagian pasukan yang mewakili SEPINTAR dalam Solar Boat Challenge anjuran BP MyScience Project ke Karnival Sains peringkat daerah Gombak yang bertempat di SMK Sungai Pusu diiringi oleh Puan Norazrina binti Safree dan Puan Noor Farihana binti Mohamad Supi. Objektif lawatan ini adalah untuk ;
  •          Mencari informasi mengenai Solar Boat
  •           Mengkaji model-model Solar Boat

Mereka telah menemu ramah hakim pertandingan bagi mendapatkan maklumat sekaligus dapat menjana idea bagi pertandingan yang akan datang. Pelbagai ilmu dan nasihat keramat telah diperoleh.

Sebaik sahaja tiba di bumi SEPINTAR, pelajar-pelajar ini telah mereka dan membuat satu model Solar Boat dengan bantuan guru pembimbing. Model ini telah dihasilkan berasaskan pengujian terhadap keseimbangan dan keapungan solar boat ini. Alhamdulillah, walaupun tempoh penghasilan ini hanyalah selama 3 jam, tetapi mereka berjaya menggerakkan boat itu. Walaubagaimanapun, terdapat sedikit kesilapan yang dilakukan. Bot ini bergerak secara terbalik / mengundur akibat tersalah pateri motor. Mereka akan melakukan ujian kedua dengan mengubah beberapa aspek bot. Nantikan perkembangan pasukan Solar Boat Challenge Sepintar pada episod akan datang ! Wassalam.

How Do Solar Panels Work?



      Solar panels collect solar radiation from the sun and actively convert that energy to electricity. Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy. The energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current, from which metal contacts in the solar cell can generate electricity. The more solar cells in a solar panel and the higher the quality of the solar cells, the more total electrical output the solar panel can produce. The conversion of sunlight to usable electrical energy has been dubbed the Photovoltaic Effect.

       The photovoltaic effect arises from the properties of the p-n junction diode, as such there are no moving parts in a solar panel.





       The factors that affect the output of solar panels are weather conditions, shade caused by obstructions to direct sunlight, and the angle and position at which the solar panel is installed. Solar panels function the best when placed in direct sunlight, away from obstructions that might cast shade, and in areas with high regional solar insolation ratings.
Solar panel efficiency can be optimized by using dynamic mounts that follow the position of the sun in the sky and rotate the solar panel to get the maximum amount of direct 
exposure during the day as possible.

HISTORY of SOLAR THERMAL


        With an abundance of solar energy - enough shining on the Earth every hour to meet the world demand for an entire year - it's no surprise that solar radiation has time and again been harnessed to meet the growing needs of mankind.

        From ancient Mediterranean homes built to face the sun during the cold winter months to highly sophisticated thin-film photovoltaic cells, which generate electricity from sunlight, solar energy continues to be a leading source of alternative energy.


         In 1912, these parabolic solar collectors, built on a small farming community on the Nile River 15 miles south of Cairo, Egypt, were developed by a Philadelphia inventor, entrepreneur, and solar visionary named Frank Shuman. Each collector was 204 feet in length, 13 feet in width and was fitted with a mechanical tracker which kept it automatically tilted to appropriately absorb the sun.

        The heat collected by these reflectors was used to produce steam to power a series of large water pumps. Together they produced the equivalent of 55 horsepower and were capable of pumping an astonishing 6000 gallons of water per minute, bringing irrigation water to vast areas of arid desert land.








Shuman (pictured on the left) planned to build more than 20,000 square miles of these solar reflectors in the Sahara but was forced to shelve the idea due to the outbreak of World War I.
       After the war, as the world discovered the vast oil fields in Iraq, Iran, and Venezuela, the allure of limitless solar energy was diminished and Shuman returned to his hometown of Tacony, in Pennsylvania, never to realize his dreams and visions.

         Solar radiation, an emission-free and inexhaustible supply of energy, is the most abundant of all known energy sources in the world. Utilizing solar technology and other forms of renewable energy helps to reduce reliance on fossil fuels for energy production, thus directly reducing CO2 emissions which contribute to artificial climate change and global warming.

Earth Day !!

Gaylord Nelson
      Earth Day is a day that is intended to inspire awareness and appreciation for the Earth's natural environment. Earth  Day was founded by United States Senator Gaylord Nelson as an environmental teach-in first held on April 22, 1970. Over 20 million people participated that year, and Earth Day is now observed on April 22 each year by more than 500 million people and several national governments in 175 countries.

      Earth Day is becoming one of the most important hallmarks in the world of conservation and recycling. Earth Day gives those people who have not taken part in recycling the opportunity to make changes to their lives and their community that they will cherish for a lifetime.

Solar Boat Briefing



On 12th April of 2011, SBP Integrasi Rawang had send five students and two teachers to SMK Alam Megah to attend a Solar Boat Briefing as part of BP MyScience Project 2011. We reached the school at 9.45 a.m.. Before the briefing started, we were served with breakfast. Mrs. Salamah Abdul Manaf, one of the GPKs SMK Alam Megah welcomed us with a short welcoming speech. The briefing was given by BP Representative, Mr. Zukifli Othman and Mr. Koh Kian Choon.

This Solar Boat briefing was attended by five schools from Selangor, namely SMK Alam Megah, SMK Saujana Impian, SMK Tengku Ampuan Rahimah, SMK Sri Permata and our school, SBP Integrasi Rawang. Mr. Koh and Mr. Zukifli had explained to all the participant the vision and objectives of Solar Boat Competition. They also gave the criteria on new fresh ideas on boat design and PowerPoint presentation. 

This year’s competition was being stricter terms and conditions will be enforced. It is SBP Integrasi Rawang’s first participation in this National competition. Therefore, we expect it to be challenging. In the end, Mr. Koh gave each school three solar panels and a motor. This briefing ended at 11.55 a.m.. We were served with a delicious meal before going back. We reached our school at 1.30 p.m.. Even though, this is new to us, we hope that we can do the best for our school.

Trading Game and Carbon Challenge Report

On the 28th March 2011, the Carbon Challenge and Trading Game was held at the Al Aqsa Hall of SBP Integrasi Rawang.  This activity was carried out from 9 am until 3.00 pm. The students that have taken part in this activity were students from Form 4.  75 Science Stream students have taken part in Carbon Challenge while the 80 Science Islamic student in Trading Game.
Briefing from Mr Zukifli Othman

These activities were conducted entirely by BP. A representative from BP, Mr. Zukifli Othman, the External Affairs Manager was present for the both activities.
            The ceremony then proceeded with the Trading Game. Trading Game is about having fun with mathematics especially the calculation skills while learning how to be a good trader/accountant/market analyst of a company. Mr. Zukifli has given little information about the Trading Game before he started the game.

Bip for the players
Before the Trading Game gets started, students were put in 17 groups. Each group consists of 5 people and was asked to appoint a Chair Person, an Accountant, a Market Analyst and a Trader.


Some form four students in SBPI Rawang that participate in the game

This game is divided into 2 rounds. The first round was the practise round and the second round was the competition round. The practise round is to ensure the participants understand how to play the Trading Game. During the competition round, the participants  had to make the right decision in order to win. For this round, each team was given RM50,000 and a 1000 barrels of oil as initial capital.
        
Winners of Trading Game
                                                                                                         "I can understand 
the intricacies
                                                                                                         of business accounts and to
                                                                                                  become

        After the Trading Game activity, the Carbon Challenge activity was carried out. Carbon Challenge is about expanding and testing our knowledge of the environment. Plus, Carbon Challenge is informing students about our carbon footprint, how important is the environment to the people and some IQ test about green-awareness. Each participant was given a remote which also known as ‘Turning Point Remote’. This Turning Point Remote is used to answer the questions provided

Presentations from selected groups

                                                                               "I realized that to save the world from pollution                                                                               is not easy but if everyone on Earth to contribute                                                                                to this effort, then our future will not be dark"                                                                                             -SYAWAL B. NASARUDDIN-
         
         Lastly, in conclusion, students had lot of fun gaining some new knowledge about our environment and they learned how to be a successful person in business.
