essay
1. Wind power generation pointed out as kind of energy with the fastest growthrate in the world today, why the Indonesian state has not implemented fullyhydro(PLTN) ?
Answer:statistical areas in Indonesia are less fully support because it does not allareas / regions in Indonesia potential. only in the tip of Sumatra and theeastern area of Indonesia that coverage will very much lah. that is why theIndonesian state has not fully switched to nuclear power plants. and onemore thing the wind power is not stable in all regions Indonesia.
2. to Indonesia with an estimated average wind speed - average about 3 m / s.whether the right turbine in use in Indonesia?
Answer:small-scale turbines more suitable for use in Indonesia, the difference affectsthe capacity of the initial minimum speed requirement (cut in win speed) thatneed large-scale turbines operate on the cut to win speed 5m / s while thesmall-scale turbines can work 3m /s.

soal 1in areas where there is only allowing its nuclear power plant in Indonesia?and whether nuclear power could be applied in Indonesia we know the range ofissues existing nuclear radiation?
Answer:indeed there are still cases like that. because the country who can build a nuclear
power plant must have a high stability both political and other. foreign parties mustlimit, because there is an international nuclear agency IAEA name, and it is not onlytaking care of one country alone but lot.
soal 2We know the construction of PLTN in Indonesia is a lot of Controversy, like where doyou personally respond to this?and here you think TV is more dangerous radiation from the nuclear radiation, how?
Answer:
Radiation tu TVs larger than the nuclear radiation. imagine if you watch TV, howmany hours you are stronger? It can damage organs of the eye.while waiting for the other alternative energy, while the war to the WHO Thosecountries want to boycott us. prevented positive creative people. may not dunkz!God created the earth and sky tu emang studied in order to make us more Cautiousand Recognize the Greatness of God! !

7. why nuclear development could be an alternative to overcome the energy
crisis ?
a new alternative energy and other renewable energy such as
geothermal, wind, ocean waves, etc. should be optimized first. If these
energy reserves are exhausted, then the nuclear energy as a last resort.
Another reason is, the technology of carbon emission-free nuclear power
plants as well as harmonious with the world efforts in combating global
warming.
8. What is the factors that impede the development of renewable energy?
- fossil fuels are still subsidized by the government so that new and
renewable energy to compete in terms of price
- the lack of interest in renewable energy to develop this energy
- until recently the development of technologies for new and renewable
energy is still lacking

2.What is the advantages of biogas?
Answers
1. Biogas is gas produced by anaerobic activity or fermentation of organic materials
including: human and animal excrement, domestic waste (household),
biodegradable waste or any organic wastes are biodegradable in anaerobic
conditions. The main content of the biogas is methane and carbon dioxide.
2
1. Biogas does not destroy the balance of carbon dioxide caused by deforestation
(deforestation) and destruction of land
2 Energy Biogas can serve as an energy substitute for fossil fuels that would reduce
atmospheric greenhouse gases and other emissions.
3 Methane is a greenhouse gas whose existence duatmosfer will increase the
temperature, by using biogas as a fuel it will reduce methane gas in the air.
4 Waste in the form of animal manure and human waste is material that is not

d. Pollution of greenhouse gases (mainly CO2) from burning fossil fuels.
Answer : C
2. Essay
1. Why the scarcity of fuel Is a sight that can be found in various regions in
the country?
Answer : Because oil price hikes up to U.S 70/barrels affect economic
activity in various part of the world. Example in Indonesia the Crisis wasworsened by the rampart smuggling of oil that allegedly loss the state up
to 8,8 trillion dollar per year and it is can be like that because of the
weakening rupiah against the dollar and there government of Indonesia
must the serious to share about the problem.
2. Give your listen, what the government must to do dependence on fossil
fuels not to be serious threat to the lives of living creatures on earth?
Answer: The development and implementation of renewable fuel is
environmentally friendly need to get serious attention from various
countries. But in the real government actually has prepared a variety ofregulations to reduce dependence on fossil fuel. Unfortunately, at the
level of implementation has not seen any serious and systematic effort to
implement renewable energy to substitute and with close cooperation
between government, industry and society, bio-ethanol and biodiesel are
the two candidate who could be implemented to reduce depence on fossil
fuels.

3. What is the process of making Crude Jatropha Oil (CJO)?
- The jatropha seeds cleaned of debris washed by manual or machine
- Seeds were soaked for about 5 minutes, then drained until the water no longer drips
- Seed are dried using a dryer with drying tool, then the seeds are put into a centrifuge to
separate the flesh from the skin grain seeds
- Meat seeds that have been separated from his skin, rolled and ready to be pressed. Long
period of grinding to a pressing must fast because avoid oxidation
- The process of pressing usually leave residu which still contain 70-10 % oil. Therefore,

essay:
1. what must we do to face the crisis energy?answer : we can use renewable energy such as biomass, solar cell and etc.
or we can use energy with good management, so there isn0t loss energy.
2. why must we optimalizate energy?
answer : because the energy sources are less. Coal will used up until 50 years later,
natural gas will used up 30 years later and patroleum will used up 10 year later.
the reservation will used up if we don't find an0ther the sources.So, we must to
optimalization energy
