1. Directive (the same as practice – practice sebelumna)
2. Keselamatn Keja (same as practice – practice earlier)
3. Equipment and supplies (the same as during the previous practice)
4. Work Steps
For example, points P and Q are points of a large building, it takes two to put the dots located on one line with P and Q (located between point P and point Q).
Yalon holding the first and second person holding a yalon. The second man tried to put yalonnya at point b1 and the first place the yalonhya in point a1, the way the two are mutually aim / look at that point b1, a1 and P and a 1 and b 1 Q looks a straight line.
Measure the distance between two dots in the field.
Hint, keselamatam work and equipment together with previous practice (crockery plus pen steel or stakes of bamboo / wood) When using a measuring tape, both of material linen fabric, fiber glass and steel, it must be careful because the numbers are easily erased and when entwined over time can be broken. Measuring tape ends have links (grip) and a dotted 0 at a distance of 10 cm from the handle.
Work steps:
Carried out by at least two people.
a. Define the points to be measured (eg point A and point B).
b. If the distance exceeds the length of the measuring tape, then the distance AB is divided into several times the length of the measuring tape, with the help of yalon, do as the steps to make a straight line on the ground, so that the distance AB or AB lines really straight, so the distance is very thorough.
c. So that the distance is really flat, then use a spirit level carpenter / mason (so that the measuring tape is always horizontal position)
d. To support the calculation of distance, usually menggunanakan pen steel or bamboo stakes
e. Pen steel / bamboo stakes helpful to calculate the measurement step. For example, the first at the end of the measurement to collect 11 pieces of pen means the number of steps 11-1 = 10. Thus, the distance measured 10 x length of the measuring tape, measuring tape when the length of 20 m, the distance = 10 x 20 m = 200 m, plus the rest are probably less dai 20 meters (8 meters) so pangjang a total of 208 meters.
