Abstract
Self Propelled Coal Barge (SPCB) atau tongkang batu bara bermesin penggerak
sendiri adalah teknologi baru yang digunakan dalam distribusi batu bara antar pulau.
SPCB memiliki kelebihan efisiensi dibandingkan dengan tongkang yang masih
ditarik oleh kapal tunda (tug boat) untuk bergerak. Pada penelitian ini akan dikaji
keandalan struktur kekuatan memanjang SPCB. Variasi tinggi dan periode
gelombang diaplikasikan dalam rangka pencarian distribusi bending moment. Variasi
tinggi gelombang yang digunakan sebesar 0,5–4,5 m dan variasi periode gelombang
3,5–13,5 sekon. Distribusi bending moment mengikuti distribusi normal dengan nilai
rata-rata sebesar 21069,017 MNm pada kondisi sagging dan sebesar 20984,63 MNm
pada kondisi hogging. Nilai standar deviasi bending moment sebesar 5640,628 MNm
pada kondisi sagging dan 3903,234 MNm pada kondisi hogging. Analisis
perhitungan modulus penampang dilakukan dengan perhitungan manual berdasarkan
Rawson, K J. dan Tupper, E. C. (2001). Analisis keandalan Pada kondisi sagging
menunjukkan struktur memiliki keandalan sebesar 1 untuk 10 dan 100 kali simulasi.
Keandalan terkecil sebesar 0,9983 terjadi pada saat 100000 kali simulasi. Pada
kondisi hogging, struktur memiliki keandalan sebesar 1 untuk 10, 100, 10000 dan
10000 kali simulasi. Keandalan terkecil sebesar 0,999902 terjadi saat 1000000 kali
simulasi.

Self Propelled Barge Coal (SPCB) is a new technology used in coal distribution
between islands. SPCB has efficiency advantages compared with a barge that was
pulled by tugboat (tug boat) to move. In this study will be assessed the reliability of
longitudinal structure extends SPCB. Variations height and wave period is applied in
order to find the distribution of bending moment. Wave height variation which is
used extends from 0.5 to 4.5 m and wave period variation from 3.5 to 13.5 second.
Bending moment distribution follow a normal distribution with an average value of
21069.017 MNM in sagging conditions and 20984.63 MNM in hogging conditions.
Standard deviation value of bending moment is 5640.628 MNM in sagging condition
and 3903.234 MNM in hogging condition. Analysis section modulus calculation
performed by manual calculation based Rawson, K J. and Tupper, EC (2001). In the
reliability analysis showed in sagging condition of the structure has a reliability of 1
to 10 and 100 times the simulation. The smallest reliability of 0.9983 occurs during
simulation 100000 times. At hogging condition, the structure has a reliability of 1 to
10, 100, 10 000 and 10000 times the simulation. The smallest reliability of 0.999902
occurs 1000000 times simulation.
