Abstract
ABSTRACT
The stability of a construction building is the most important thing in its
planning. As is the case with the construction of the retaining wall in the Intake
Infrastructure Development Project and the Sepaku River Transmission Pipeline,
North Penajam Paser Regency, Sukaraja Region, Kec. Sepaku, East Kalimantan,
76147. This research was conducted to determine the value of the factor of safety
for a cantilever type retaining wall and to calculate the reinforcement to ensure
the safety of the structure. Research on the analysis of the stability of this
retaining wall, will be analyzed manually.
The method carried out in this study involves the following steps. First,
data collection is carried out regarding the condition of the soil in the location to
be reviewed. Next, an analysis was carried out on the forces acting on the soil
retaining wall, including the lateral pressure of the soil and the load acting on the
soil retaining wall. This analysis will produce a safety factor of stability of
cantilever-type soil retaining walls.Next, the calculation of the repetition of the
soil retaining wall is carried out to guarantee the strength and rigidity of the
structure.
The results of the stability analysis of the cantilever-type soil retaining
wall against shear obtained a value of 9,06 > 1.5 (safe), stability against rolling
obtained a value of 7,58 > 1.5 (safe). The results of the stability analysis of the
cantilever-type soil retaining wall against the strength of the soil carrying
capacity obtained a value of 32,17 > 3 (safe). As for the calculation of repetition
on the soil retaining wall, for pieces I – I using 13 mm reinforcement with 54 rods
of reinforcement, pieces II – II using 22 mm reinforcement with 19 sticks of
reinforcement, pieces III – III using 19 reinforcement with 25 sticks of
reinforcement, pieces IV – IV using 13 mm reinforcement with 64 sticks of
reinforcement, V – V cuts using 16 mm reinforcement with a total of 42 rods.
Keyword: Retaining wall, cantilever type, analysis, calculation of reinforcement,

ABSTRAK
Kestabilan suatu bengunan konstruksi merupakan hal yang paling penting
dalam perencanaannya. Seperti halnya konstruksi dinding penahan tanah yang ada
pada Proyek Pembangunan Prasarana Intake dan Jaringan Pipa Transmisi Sungai
Sepaku, Kabupaten Penajam Paser Utara, Daerah Sukaraja, Kec. Sepaku,
Kalimantan Timur, 76147. Penelitian ini dilakukan untuk mengetahui nilai faktor
keamanan dinding penahan tanah tipe kantilever serta perhitungan penulangan
untuk memastikan keselamatan struktur tersebut. Penelitian tentang Analisis
stabilitas dinding penahan tanah ini, akan dianalisis secara manual.
Metode yang dilakukan dalam penelitian ini melibatkan langkah-langkah
berikut. Pertama, dilakukan pengumpulan data mengenai kondisi tanah dilokasi
yang akan ditinjau. Selanjutnya, dilakukan analisis pada gaya-gaya yang bekerja
pada dinding penahan tanah, termasuk tekanan lateral dari tanah dan beban yang
bekerja pada dinding penahan tanah tersebut. Analisis ini akan menghasilkan
faktor keamanan stabilitas dinding penahan tanah tipe kantilever. Selanjutnya,
dilakukan perhitungan penulangan dinding penahan tanah untuk menjamin
kekuatan dan kekakuan struktur.
Hasil analisis stabilitas dinding penahan tanah tipe kantilever terhadap geser
diperoleh nilai sebesar 9,06 1,5 (aman), stabilitas terhadap guling diperoleh
nilai sebesar 7,58 1,5 (aman). Hasil analisis stabilitas dinding penahan tanah
tipe kantilever terhadap kuat daya dukung tanah diperoleh nilai 32,17 3 (aman).
Sedangkan untuk perhitungan penulangan pada dinding penahan tanah, untuk
potongan I – I menggunakan tulangan 13 mm dengan jumlah tulangan 54 batang,
potongan II – II menggunakan tulangan 22 mm dengan jumlah tulangan 19
batang, potongan III – III menggunakan tulangan 19 dengan jumlah tulangan 25
batang, potongan IV – IV menggunakan tulangan 13 mm dengan jumlah tulangan
64 batang, potongan V – V menggunakan tulangan 16 mm dengan jumlah
tulangan 42 batang.
Kata kunci: Dinding penahan tanah, tipe kantilever, analisis, perhitungan
penulangan, struktur.
