Mentors with students

Mentors with parents and students

STEP 1: IDENTIFYING GLOBAL SIGNIFICANT ISSUES

Jakarta had the worst air quality in the world, according to AirVisual, an air quality monitoring app. With an Air Quality Index (AQI) of 210, Indonesia’s capital easily ranked above other notoriously polluted cities, such as Beijing, Dubai, and New Delhi.

So, when we discuss about worst quality of Jakarta, when will it end to a discussion or we can do something as our action to reduce the air pollution?
That's why the students choose the topic " How to reduce air pollution" as their concern in their exhibition.

The students joined a seminar in @america, Pacific Place Mall, South Jakarta on January 30th, 2020. They gained a lot of information that can be use as our prior knowledge, how to reduce mercury emissions from coal in Indonesia, what the effects from the air pollution are, what the solution is, etc.

The students did an experiment to check the air pollution around our school and our home. Based on the pollution catcher experiment, they get know that air quality in Jakarta worst and one of the cause of air pollution is emissions from transportation, motor cycle. It proves when the students also put the pollution catcher in one of the mentor's motor cycle.

STEP 2: DETERMINING TIMING AND TIME FRAME

Making Connections Between Previous Learning and Current Learning

Prior Knowledge:
•K2: Transportation
Students learnt about transportation when they were in K2 and it relates to their exhibition topic, how the transportation also affect to the air pollution, and also which transportation that contain lead materials produce air pollution.
•G2: Building and structure, and Natural habitat.
Students learnt about building & structure, also natural habitat when they were in G2. It connects how the building and structure give effect to the air pollution because of lead materials and its influence to the natural habitat.
•G3: Human body system.
Students learnt about human body system when they were in G3 and it relates how the effect of lead materials to human health.
•G4: Economic activity.
Students learnt about economic activity when they were in G4 and it relates how human and economic activities can have negative impact to environment.

step 3: engaging support from the learning community

Collecting Data and Reporting Finding/Researching and Seeking Information

We went to KPBB ( Komite Penghapusan Bensin Bertimbel) to collect information about how KPBB collaborate with the government in managing lead gasoline and solution for air pollution that caused by it. The result was KPBB succeeded in convincing the government to collaborate in managing lead. The gasoline from PERTAMINA no longer using lead. KPBB also organized workshop to educate people the danger of lead gasoline and how to reduce air pollution.
In PERTAMINA, students learned about other solution in producing less pollution gasoline by mixing 30% palm oil with 70% gasoline, and the product name is B30.

STEP 4: organizing and learning

The gasoline that powers the vehicle doesn't occur naturally like water in a stream. So where does it come from? Gasoline actually must be produced from a thick, dark substance pumped from deep underground. We call that substance crude oil or petroleum. The students learned about the composition of gasoline from Ms. Beta, she has background in chemical study and know about the lead materials.

They also learnt about octane number. The octane rating or number is a measure of the resistance of gasoline and other fuels to detonation (engine knocking) in spark-ignition internal combustion engines. High-performance engines typically have higher compression ratios and are therefore more prone to detonation, so they require higher octane fuel. A lower-performance engine will not generally perform better with high-octane fuel, since the compression ratio is fixed by the engine design.

The octane number of a fuel is measured in a test engine, and is defined by comparison with the mixture of iso-octane and normal heptane which would have the same anti-knocking capacity as the fuel under test: the percentage, by volume, of iso-octane in that mixture is the octane number of the fuel.
For example, gasoline with the same knocking characteristics as a mixture of 90% iso-octane and 10% heptane would have an octane rating of 90. Because some fuels are more knock-resistant than iso-octane, the definition has been extended to allow for octane numbers higher than 100.

STEP 5: monitoring the exhibition

Research Finding
Experiment to test the lead levels in 3 samples of gasoline (Pertalite, pure Pertamax and retail Pertamax), the result are the material level of Pertalite, pure Pertamax and retail Pertamax are 0,001 g/l

STEP 6: sharing the exhibition
consider action on learning
"Social Entrepreneurship, Participation, and life style choice"

Social Entrepreneurship, Participation, and life style choices

The students did their action by going to school using school bus, car pooling, and walking to school. Those are their action in reducing the air pollution. They also designed T-shirt Pins as a campaign to stop air pollution.

The students found that a strong commitment by the people is the key to significant improvement of the city's air quality, and so are we ready to work together in significantly clean up the city’s air?
The greater our commitment, the cleaner Jakarta’s air will be.
