| dc.description | Self-comcpacting concrete (SCC) merupakan suatu inovasi dari beton
konvensional yang mampu mengisi ruang–ruang didalam cetakan tanpa proses
pemadatan, dan mampu mengalir dengan berat sendirinya. Beton jenis ini dapat
memadat sendiri dan memliki workability tinggi sehingga tidak dibutuhkan alat
bantu vibrator dan compactor untuk memadatkannya. Self-compacting concrete
harus mampu menahan gaya tekan dan lentur sehingga bangunan tidak mengalami
kegagalan struktur, stabil dan aman. Kuat lentur dapat diprediksi menggunakan
logika fuzzy. Logika fuzzy merupakan logika untuk menyelesaikan masalah dengan
memetakan ruang input ke dalam ruang output. Penelitian ini bertujuan untuk
mengetahui prediksi nilai kuat lentur self-compacting concrete menggunakan
logika fuzzy terhadap jumlah material yang digunakan. Pemodelan dilakukan
dengan metode fuzzy mamdani yang terdapat pada toolbox software MATLAB
dengan fungsi keanggotaan representasi kurva trapesium. Prediksi nilai kuat lentur
selanjutnya akan dibandingkan dengan data sekunder yang diperoleh dari penelitian
sebelumnya tentang self-compacting concrete. Hasil pemodelan menunjukkan
bahwa prediksi nilai kuat lentur logika fuzzy mendekati nilai kuat lentur
laboratorium dengan presentase error rata-rata sebesar 5,79% dan simpangan nilai
kuat lentur sebesar 4,20%, sehingga nilai kuat lentur tidak jauh berbeda. | en_US |
| dc.description.abstract | Self-compacting concrete (SCC) is an innovation of conventional concrete that is
able to fill spaces in the mold without the compaction process, and is able to flow
by itself.This type of concrete can solidify itself and possess high workability so it
does not need a vibrator and compactor tool to compact it. Self-compacting
concrete must be able to withstand compressive and bending forces so that the
building does not experience structural failure, stable and safe. Flexural strength
can be predicted using fuzzy logic. Fuzzy logic is a logic for solving problems by
mapping input space into the output space. This study aims to determine the
predictions of the flexural strength of self-compacting concrete using fuzzy logic to
the amount of material used. Modeling is done by the fuzzy mamdani method found
in the MATLAB software toolbox with the membership function of the trapezoidal
curve representation. The prediction of the next flexural strength will be compared
with secondary data obtained from previous research on self-compacting concrete.
The modeling results show that the predictive value of fuzzy logic flexural strength
approaches the laboratory flexural strength with an average percentage error of
5.79% and a deviation of flexural strength value of 4.20%, so that the flexural
strength value is not much different. | en_US |
