It is well known that some trees live for a very, very long time. Have you not heard about the walking mango tree of Gujarat? Its branch produces fresh roots and when the old tree dries up, a new one, developed from this branch, takes its place.
Unlike animals, a tree goes on growing, both at the top as well as at the roots. Death can happen only when growth ends. What happens, in practice, is premature death, on account of a variety of causes like uprooting by storms, attack by fungi and above all, by greedy Man!When the tree becomes too tall, the trunk develops fatigue. If by a conscious effort, we try to prop up a tree and ensure supply of water, it is my belief that the tree will not die. Some institution may take up this project.

Can Biodiesel compete with petroleum diesel?
Viewed in terms of price, biodiesel is not going to produce a cheaper price compared with petroleum diesel, but in terms of alternative environmentally friendly energy, and efforts to build national resilience in the fields of energy, then biodiesel is feasible to implement.
At present Indonesia is one country which subsidizes fuel prices and do not attract tax. Surely this will lead to various kinds of alternative energy programs will never successfully executed, the people lulled by cheapening the price of kerosene, diesel fuel prices, etc.. Unlike other countries that actually gives tax on fuel prices. Thailand is a country that has the lowest fuel taxes in the world, applying an average tax of 22% to the price of fuel is marketed in his country.

Biodiesel Handling Products
Biodiesel is a product that is not toxic and biodegradable, so the handling is much easier and simpler than petroleum diesel fuel materials.
Activities blending biodiesel and petroleum diesel does not require complicated handling, because without the pengadukanpun both materials will be mixed with a perfect and stable.

Microorganisms that exist in the nature of this has morphology, structure and
distinctive traits, as well as bacteria. Bacteria that live almost no
color and contrast it with water, in which bacterial cells are suspended.
One way to observe the shape of bacterial cells making it easy to
is identified with a method of painting or staining. It also
to know the nature of the physiological function that describes the reaction of the cell wall
bacteria through a series of painting (Dwidjoseputro, 1994).

CHAPTER I: INTRODUCTION
1.1 Background
Protein (the root word from the Greek protos, meaning "the ultimate") is a complex organic compounds of high molecular weight polymer of a monomer-monomer amino acids linked together by peptide bonds. Protein molecules containing carbon, hydrogen, oxygen, nitrogen and sometimes sulfur and phosphorus. Protein plays an important role in the structure and function of all living cells and viruses.
Most proteins are enzymes or enzyme subunits. Other types of proteins play a role in structural or mechanical functions, such as proteins that form the stems and joints Cytoskeleton. Protein involved in the immune system (immune) as an antibody, the control system in the form of the hormone, as a storage component (the seeds) and also in the transport of nutrients. As one source of nutrition, proteins serve as a source of amino acids for organisms that are not able to form these amino acids (heterotrof).

Synthesis section 
In this section urea is made from carbon dioxide gas, liquid ammonia, and the solution karbamat byrecycle. The main tool is the synthesis reactor (DC-101) of the vessel upright on the operating temperature of 195 0C and pressure of 200 kg/cm2. This reactor provides sufficient volume to conduct the reaction of urea synthesis, as close as close to the equilibrium reaction. According to the design capacity, residence time in the reactor is 25 minutes. Because the reactant and product substances are corrosive then the entire surface of contact with the solution given the protective layer of stainless steel. Usually stainless steel and stainless steel are also
