modern (baru)
 Rambu ukur (baak) baik dilengkapi dengan mistar
skala maupun tidak
 Sepatu rambu sebagai alas dari rambu ukur
 Statif rambu untuk menjaga rambu supaya tidak
jatuh
 Nivo kotak untuk membuat rambu supaya tidak
miring (baik kemuka atau kebelakang dan ke kiri
atau ke kanan

 Jarak antara TSR (benang atas) dan BSR (benang
bawah) disebut interval stadia .
September 5, 2016 pengukuran Beda Tinggi - MGR 30
Hor. Dist. = SI x SF
SI = Stadia interval
SF = Stadia factor

31. TGM
UGM Garis silang
merupakan garis
kolimasi
 BB dan BA disebut
dengan garis stadia
 Biasanya stadia
mempunyai faktor
pengali 100
September 5, 2016 pengukuran Beda Tinggi - MGR 31

32. TGM

 BA = 3.040
 BB = 2.946
 BA – BB = 0.094
 Jarak optis =
0.094 x 100 = 9.4
metres
September 5, 2016 pengukuran Beda Tinggi - MGR 32

33. TGM

September 5, 2016 pengukuran Beda Tinggi - MGR 33
Hor. Dist. = TSR - BSR( )x SF
Dist = TSR - BSR( ) x SF
= 6.01 - 5.47( ) x 100
= 0.54 x 100
= 54 ft

34. TGM
UGM
September 5, 2016 pengukuran Beda Tinggi - MGR 34
Dist = TSR - BSR( ) x SF
= 7.844 - 4.619( ) x 100
= 3.225 x 100
= 322.5 ft

35. TGM
UGM
Apabila Benang atas atau benang
bawah terhalang, bisa digunakan
cara ½ stadia. ½ stadia adalah
setengah dari interval stadia
September 5, 2016 pengukuran Beda Tinggi - MGR 35
Contoh :
Jika TRS = 7.34 dan
elevasi 6.21, maka jarak
mendatarnya :
Horizontal Distance = TSR - Elev( )x 2[ ]x 100
= 7.34 - 6.21( )x 2[ ]x 100
= 226 ft

 Ada beberapa faktor yang mempengaruhi kesalahan
pengukuran beda tinggi yang menggunakan penyipat
datar, di antaranya ::
 • Kesalahan garis kolimasi
 • Karena kelengkungan bumi
 • Kesalahan refraksi (undulasi)
 • Kesalahan paralaks

PENGUKURAN TITIK KONTROL VERTIKAL
1.Pengukuran tinggi titik-titik kontrol vertikal dilakukan dengan
metode sipat datar. Spesifikasi pengukuran adalah sebagai
berikut:
2.Sebelum alat digunakan harus dicek garis kolimasinya
terlebih dahulu.
3.Pengukuran beda tinggi dalam satu seksi dilakukan pergi
pulang dalam satu hari.
4.Jarak maksimum antara alat sipatdatar ke rambu 60 meter.
5.Kedudukan alat pada setiap slag pengukuran harus pada
jarak yang sama antara jarak instrumen ke rambu depan dan
instrumen ke rambu belakang.
6.Kesalahan penutup maksimum ukuran pergi-pulang sebesar
10 mm √L (L: dalam kilometer).

 A benchmark in every-day language is a point
of reference for a measurement. In surveying a
benchmark is specifically any permanent
marker placed by a surveyor with a precisely
known vertical elevation (but not necessarily a
precisely known horizontal location). Designed
to be used for many projects.

• It is more convenient for “Area Levelling” and can become
cumbersome on long traverses.
It is also an easier method for “On the Fly Levelling”
• Also Known as Instrument Height Method

 Definition – Misclose- is when closing
of a traverse due to errors in readings
and instrument limitations there is a
discrepancy.
 The allowable discrepancy is (12 x square
root of traverse in kilometres)

UGM
 Traverse Length = 190 metres
 Allowable Misclose = 12 x SQRT(0.190)
= 12 x 0.4359
= 5.23mm
