kinetic energy and gravitational potential energy, including energy called mechanical energy. makanik energy is the amount of potential energy and kinetic energy possessed by an object, and is also the total energy. amount of mechanical energy of an object is always fixed, while the kinetic energy and potential energy can be changed-ubah.energi potential + kinetic energy.
formula: E = Em + Ek

example:
a body is at rest at a height of 80 cm, 5 kg of body mass, and acceleration of gravity g = 10 m/s(squared). determine the mechanical energy of the object.

resolution:
means it does not have the speed or v = 0, whereas the object height h = 80cm = 0.8 m.

then: Em = Ep + Ek = mgh + 1/2mv (squared) = 5.10.0,8 + 0 = 40 joules.

so, the mechanical energy of objects that dwell on the table will be equal to the potential energy, since kinetic energy is zero.

Tools hammers used in the work plate manifold and it's all depending on the type of use. In general a hammer into two types, namely a hammer used to hit the plate and used to hit iron. To beat or zinc plate to use plastic or wooden hammer, to strike while the iron or the like used sledge hammer. Error using a hammer this will result in damaged platnya or palunya. For example, to pave the iron plate using a hammer, the zinc coating will flake off, so this will cause the plate to peel, so if you want to hit the iron or the like using a hammer or a plastic timber, then the hammer will be damaged. Sledge hammer has a form of the manifold, depending on usage.
Various iron Hammer / hammer hard:
a. hummer konde: used to beat rivet and strengthen the connection plate and the other jobs that need to be a light beating.
b. hummer Pelipat: Hammer is used to fold the edges on the plate, especially in the pengawatan.
c. hummer pen: is used to smooth the connection and also to beat the light.
d. hummer pengeling: used for the formation of rivet
e. hummer peregang: tense is used to plate.
f. Straighten hummer: used to refine the end of the form of work.
g. Transverse hammer, a hammer is used to thin this material.
h. hummer arch: a hammer is used to form objects that curve.

Surely man was created by Allah SWT is the most perfect machluk compared with the others, including Angel, Jin, Devil, Animals, dllnya. But our own as a man does not know or do not know akan ourselves as human beings. For that let us learn about ourselves as human beings, Who is us? From which the original? How to go later? And the most important is how we lead the life of this world so that world safely and achkirat later?

for every action that is not done.
for each event that is not done ..
for every error that done ...
for every opportunity that was lost ..

I will appreciate all the more I appreciate ..
to do something this week ..

for every heart is hurt ..
for every soul that away ..
for each of the pent-up crying ..
for each of the temple of prayer for hope and strength ...

I will try harder again ..
to be a sincere man.

Salinity in the soil vary both spatial and vertical. Therefore, the measurement of adequate land must be made in both directions to obtain the exact results of the salinity in the particular field. Measurements made at high water that remains on the field will not show salinity levels in the soil. Salinity in the soil were measured at most in terms of DHL's solution to the land use DHL gauge, the units per decisiemens meters (ds / m) or millimhos per centimeter (mmhos / cm); both units is the equivalent.

Salinity in the soil can be measured through a variety of ways:

1. Saturated extracts: Use this method when laboratory facilities are available. Technique involves the measurement of DHL's solution is extracted from the pasta water saturated soil. Disuling water that is added to 200-400 g soil dry air - and stirred - until soil is completely saturated. Leave the sample at least 4 hours. Use filter penyedot (pressure plate) or centrifuge to extract water that is enough. Add 1 drops of 0.1% solution (NaPO3) 6 for each 25 mL extract. Measure tesebut extract from DHL. Measurement is abbreviated as DHLe (Electric Power Hantar extracts from). This method gives a more meaningful measure for the salinity in the soil and independent of soil texture, but requires more time.
 
2. Extract ground water: This method also requires laboratory facilities, but the method is easier than saturated extracts. Prepare a mixture of soil: water (1:5 by weight) using air dried soil and water that has been disuling. Shake for 1 hour (or when the shaker is not available, shake hands with the sample for 1 minute at least 4 times in interval of 30 minutes). Let the moment and filter lands larutannya. Add 1 drops of 0.1% solution (NaPO3) 6 for each 25 ml extract. Measure Electric Power Hantar solution of the land. Measurement depends on the texture of the soil. To convert units DHL1: 5 to DHLe; multiply by 23 (for sand, loam and loamy sand soil), with 14 (for sandy loam, light loam loamy sand), with 10 (for clay loamy, clayey silt and clay light sand), with 9 (for the sandy clay, silt, light and medium light), with 8 (for the clay are), and with 6 (for heavy clay).
   
3. Piezometers: This method is fast and can be used directly in rice fields with high water that remains. Metal or plastic pipes perforated or slit bercelah-inserted into the mire with a perforated zone which is adapted to the soil profile in which the salinity will be measured. Pipe must be long enough so that the top remain several centimeters above the high water in the rice field. Holes in the pipe must be sized small enough so that the only solution that can be ground through. When you ignore the land is a problem, pipes can be covered with cotton cloth secarik with the bottom closed. DHL's solution is to gather in the pipe can be measured using a gauge DHL.
