Good afternoon ladies and gentleman
May I introduce my self
My name is Amin Sukarjo
I am a director of TARNUS Observatory
It’s an honor to have the opportunity to introduce our invention about new sky object
It has been two years we observed it’s object, base on the prediction about object that always follow our Earth
Jupiter has it’s Trojan, and how about Earth, does Earth have it too?
Start from this question we try to hunt object that always in earth orbit
I‘ve divided my presentation into 3 parts
• POSITION
• ANALYSIS
• CONCLUSION
Here it is the TARNUS observatory that is used to observe the night sky
It has 8 m diameter and 25 m focal length, respectively.
And what we’ve got is very surprisingly, because it always closes to the sun. it just can be observed at morning or evening. So they can be called as a morning star like object or evening star like object.
This objects are very tiny, though can't be seemed by your naked eyes.
Here it is the object, the tiny one.
Because it’s always close to the sun, so we can predict that it’s position is as describe on the picture.
it’s size has approximately 10 km of diameter.
CONCLUSION
• There are two objects, orbit at the same path with Earth
• They can be called Earth Trojan “Aminoid” (proposed)
Thank you

USING OF MATHEMATICS
1. History of mathematics
The area of study known as the history of mathematics is primarily an investigation into the origin of new discoveries in mathematics, to a lesser extent an investigation into the standard mathematical methods and notation of the past.
Before the modern age and the worldwide spread of knowledge, written examples of new mathematical developments have come to light only in a few locales.
2. Using of mathematics
Mathematics is a way describing relationship between numbers and others measurable quantities. It allows scientists to communicate ideas using universally. It is truly the language of science.
For most part mathematics remains behind the scenes. We benefit from the results of mathematical research every day.
At the beginning, arithmetic, algebra, and geometry were the only mathematics disciplines.
In the past , evidence exists that early counting involved women who kept records of their monthly biological cycles; twenty-eight, twenty-nine, or thirty scratches on bone or stone, followed by a distinctive scratching on the bone or stone, for example.
Mathematical instruments discovered include an accurate decimal ruler with small and precise subdivisions, a shell instrument that served as a compass to measure angles on plane surfaces or in horizon multiplies of 40 – 360 degrees, a shell instrument used to measure 8 – 12 whole sections of the horizon and sky, and instrument for measuring the positions of stars for navigational purposes.
In a global are, the fiber optic network carrying our telephone conversation was designed with the help of mathematics. Our computers are the results of millions of hour mathematics analysis. Weather prediction, the design fuel efficient automobiles and airplane traffic control and medical depend mathematics.
Hallo ladies and gentlemans,
My name is erawati
I’m a chemistry teacher.
To day, I will present abaut polymer.
I’ve devided my presentation into 3 part.
- First of my presentation, I will present definition of polymer.
- Secondly, I present the classification of polymer
- Finally. I present the classification of polymer.
1. Definition of polymer
A polymer is a substance composed of molecules with large molecular mass composed of repeating structural units, or monomers, connected by covalent chemical bonds.
The examples of polymers include plastics, DNA, proteins, and the others.
2. Classification of polymer
Based of origin, polymer can be classified into two group :
1. Natural polymer
Natural polymer is derived from nature
The examples of natural polymer are:
a. Protein
b. selulosa
c. starch
d. natural rubber
e. glikogen
2. Synthetic polymer
Synthetic polymer is human made
The example of synthetic polymer are:
1. Nilon 66
It used to make string, parachute, fish net, rain coat, tent, etc.
2. Orlon (akrylon)
It used to make textile fibre
3. Bakelit (hidroksi metil fenol)
It used to make electric equipment
4. melamine
It used to make plastic utensil
5. Teflon (polytetra fluoro etilena)
It used to cover in pan layer
6. Polivinil Chloride (PVC)
It used to make pipe, pail, plastic chair, plastic bottle, etc.
7. Polistirena
It used to make plastic bottle of soft drink, wrap of snack, etc.
8. Dakron
It used to make textile fibre
Thank’s for your attention. See you…………
Excuse me, smoker (the accounting expert)
In cigarette many dangerous elements such as nicotine, tar, carbon dioxide, carbon monoxide, and soon. The nicotine causes the smoker addicted and very difficult to escape from the cigarette. The tar can close lungs will cause lungs diseases. The characteristic of carbon monoxide is easier closed by blood hemoglobin than oxygen. In summary the dangerous elements causes some diseases for example cancer (abnormal development of cells), heart attacking, lungs diseases, and very bad to fetus development. According the research that smoker can get crazy diseases.
To stop smoking must need the participation of the smokers, smoker environment, and government. The smoker must have an aim to stop smoking. To stop smoking need time, we can do it gradually for example if we usually smoke one pack of cigarette per day, please decrease it. One tip to stop smoking is fast. The smoker environment must conducive and help him/his to stop smoking. The government must release the regulation about prohibition to smoke (minimize in public area). As a teacher we can support this regulation that is we apply it in our school environment. We make our school free from smell smoking every time.
Therefore bad effect of smoking very much, we must stop smoking and campaign to other people. You can start from yourself, your family, your neighbor. Finally our live will save from smell smoking.
The importance of kidneys
What do your kidneys do? Why are they so important?
A. Structure of the Kidneys
The kidneys are a pair of bean-shaped organs that lie on either side of human spine in the lower middle of human back. Each kidney weighs about 0.5 percent of your total body weight or about the size of your fist. Although the kidneys are small organs by weight, they receive a huge amount (20 percent) of the blood pumped by the heart. Each kidney contains approximately one million filtering units called nephrons.
The kidneys are connected to the urinary bladder by tubes called ureters. Urine is stored in the urinary bladder until human ready to empty their bladder. The bladder is connected to the outside of the body by another tubelike structure called the urethra.
B. Function of the Kidneys
Kidney is one of the most important organs in our body. In addition to excreting urine, the kidneys maintain proper blood volume and acid-base homeostasis, regulate blood pressure, and remove the erythropoietin hormone that stimulates the production of red blood cells.
If someone has kidney problems, then all of the function above can not work well. Could you imagine how it will be? So, that is the reason why kidney is the one of the most important organ in our body.
Terrorism
When an airplane crashed World Trade Centre Building in September 11, 2001, the world’s got shock by that action. Besides, that action resulted collapses of two building and extensive damaged to nearby building, 2.974 people dead as an immediate attack. That is the kind of terrorism action, mass suicide or suicide attack.
Terrorism is unlawful act of violence to intimidate government or societies to achieve politic, religious or ideological objectives. Terrorism has a long history. It can be traced in Roman history when people resistance to Roman occupation. Modern history of terrorism was coined in the French Revolution’s Reign Terror (1793-1794).In middle 20th century, terrorism became a tool used by both sides of colonial conflicts.
There are two types of terrorism, first is domestic terrorism and second is international terrorism. Domestic terrorism is terrorism action that’s directed to the government without foreign involving. Oklahoma City bombing for example. Second, international terrorism is terrorism action that’s directed to other countries, such as September 11, 2001 bombing.
The methods of terrorism can be divided into five methods such as, firearm, explosive devices, chemical agents, biological agents and nuclear weapon. Firearm and explosive devices are the methods that‘s usually used by terrorist. Chemical agents are chemical thing that used to kill or incapacitate people. The chemical gas usually tasteless and odorless such as saran nerves. The biological terrorism use microbes, such as bacteria, viruses, toxins to produce illness, death and terror. The nuclear weapon is used by spreading radioactive materials through ventilation system or explosion.
The motives of terrorism are spread fear to societies, resistance to foreign ruler, sending a political messages and revenge to unfair treatment.
How to prevent terrorism is depend on causalities. If causalities can be eliminated, the terrorism can be eliminated too. The first thing is by education. By education, people can appreciate the differences in cultures, religions, beliefs, and human behaviors. It can also educate people that’s freedom is not just for our group but to all groups. Second, by eliminate the root of terrorism, such as social disparity, unfair treatment and poverty. Third, by establishing surveillance and monitoring system on terrorism attack, and fourth, by improving protective system for citizens.
The Composting of Garbage
Basically, composting is process fragmentation compost material with biologic way in certain temperature, with result compost ( humus ). Compost well known as organic manure, stable, low level density, and can back to the soil without high energy.
Aerobic Composting is a modification way from traditional composting. Garbage hoard heaped in a certain dimensional and density to get the temperature that needed. With Heaping Method, garbage formed good and not scattered, garbage volume can be held more, the time of composting can be controlled, and compost maturity can become perfect, decrease in stinky, and economize in water – using.
Step in composting consist of grouping, cutting, forming, sprinklings, returning through, drying, screening and packaging. Compost material will mature in 6 – 7 weeks and has characteristic is black color, not smelly, smooth texture ( likes soil ), and constant temperature ( 23-25oC). The useful is Compost as bio-activator, manure, seeding media, and soil conditioner.

DRUG ABUSE
Drug Abuse is the taking of drugs excessively, or not under a doctor’s prescription.
Effects of Drug Abuse :
o Tollerance, a condition where a person has to keep on taking more and more of a drug to achieve the same effect
o Addiction, where a person experiences withdrawal symptoms if he does not taking a drug. They include feeling :
o Physically ill (experience nausea, vomiting, uncontrolled trembling, etc)
o Mentally disturbed (experience acute anxiety, depression, etc)
Types of Drug :
Stimulant Drugs
Examples include cocaine and amphetamine stimulate the central nervous system (brain and spinal chord) by releasing neurotransmitter such as norepinephrine that increase brain activity and raise blood pressure.
Cocaine, used medically as a local anaesthetic in minor surgery.
Amphetamines are used to counteract depression, prevent fatigue and counteract hunger in patients who are dieting.
Depressant Drug
Examples include barbiturates which are used as sleeping pills. These are prescribed to overcome insomnia and to treat epilepsy.
Hallucinogenic Drugs
Examples including also called marijuana and LSD (Lysergic acid diethylamide). They cause a person to experience illusion, hallucination and distorted images.
Opiates
These includes opium, morphine, codein and heroin (narcotic drugs) because they relieve pain and induced sleep and stupor.
Heroin, made by the chemical modification of morphine. And it is several times more powerful than morphine.
The danger of this drug is that the user becomes rapidly addicted.
Another problem is that the addicts usually inject the drug directly into a vein. The hypodermic needles they share may be unsterilized and contamined, resulting the transmission of diseases such as hepatitis B, venereal diseases and AIDS.

SUBSIDY CUTTING
Pertamina was a State Enterprise,so its managed and responsibled by Governement.
Oil and fuel was one of human main life need. . Extremely oil and fuel very important of human life.
At least since 1859 oil most needed by industry as well as in household necessity,
forinstance for cooking and heating. Dailly,thousands barell oil lifted and processed from
soil and have been cosumed by industry and household . Pitiful, Pertamina can not to fulfilled the domestic demand of oil. Pertamina still import oil from the other country.
It causes World Oil price always influences domestic oil price.
Government should have policies to make society gets peaceful and prosperous. He should gives aids and efforts as far as the price of oil and fuel keep reached by domestic consumer, eventhough world 0il price is increase. .
Government must bear part of oil production Cost. Its called Oil subsidy. Its to be one of
governement expenditure on his budget.
Now adays World oil demand is rising while oil supply relatively constant. As like as an expert say that oil scarcity reaches the peak on 2025. Its make world oil price soar. And – of course – will causes the increasing of oil subsidy in governement budget. Its too hard for government to realize his welfare policy. It is make many efforets to economizing the use of oil.
Governement of Indonesia have been making policies to decrease dependency of oil.
Firstly :”Oil conversion” Which Government replaces the use kerosene stove with LPG stove especially for destitute family or among low-income households
Secondly- as a recent news- Oil Subsidy Cutting. Permited by Hause of representative, government will cutting the kerosene subsidy beginning on May. The kerosene selling
to be limited. It just sold in a 5 littres contened plastic bottle, priced Rp 47.000,00 or
US $5 each bottle and only at a legal Oil Station. The Kerosene to be scarce and its Price will increase more than 50 %.
I think its will makes many more problem,especially for kerosene user in the low-income house hold. Many person will lost theyre activities ( dor to dor kerosene retailer, bakso kupat tahu, and gorengan seller,dairy kerosene hause cooker etc).
They lost of theyre income, or must look for other job.
