Abstract

Safety road are closely related to geometric design, which includes road function, speed design, superelevation, and alignment. This paper is a geometric study to realize a safety road on Sumpiuh Ring Road, Banyumas Regency, Central Java. The locus of this research is the PI-2 and PI-3 bends located at STA. 22+213 to 22+348 which are two opposing bends that are close to each other. Measurement of existing shows that the transverse slope of the road cross-section at the peak of the PI-2 bend is 2.00% while at PI-3 it is 0.70%. With a speed of 60 km/hour, the driver will have difficulty controlling his vehicle due to centrifugal force. Such conditions make this location prone to accidents. From the analysis results, a transverse slope of 7.75% is required for PI-2, and 6.45% for PI-3. Construction adjustments need to be made to meet the needs of this superelevation design. The form of mitigation that can be done is by adding signs and road facilities such as guardrails, traffic signs such as chevron signs, speed reduction signs, rumble strips, and speed humps. This is intended to reduce the level of accidents at the location and reduce the fatalities.

Abstract

AbstrakKapal Patroli merupakan kapal yang memiliki ukuran yang relatif kecil, namun memiliki kecepatan yang cukup tinggi. Bentuk kapal yang kecil akan berpengaruh terhadap gerakan rolling kapal, sehingga menarik untuk dibahas secara mendalam pengaruh pemasangan bilge keel terhadap gerakan kapal. Penelitian ini akan menganalisis pengaruh bilge keel yang ditambah jumlahnya menjadi 2 pasang dan 3 pasang terhadap efek gerakan rolling kapal agar dapat memperbaiki performa kapal menjadi lebih baik. Model kapal patroli yang telah didesain akan dianalisis menggunakan metode BEM (Boundary Element Method) yang terintegrasi untuk mendapatkan nilai rolling pada setiap model yang dianalisis. Pada penelitian ini, didapatkan kesimpulan bahwa penambahan jumlah bilge keel akan menambah RMS rolling sebesar 11-50% pada kecepatan rendah, namun dapat mengurangi RMS rolling sebesar 7-28% pada kecepatan tinggi.Kata kunci: Bilge Keel, Kapal Patroli, Olah Gerak Kapal, Rolling.AbstractA Study on the Effects of Bilge Keel Number on 14 m Patrol Boat’s Rolling Motion: Patrol boats can move at such high speed despite their relatively small size. This relatively small size will affect its rolling motions, hence the effect of bilge keel installation on ship motions is an interesting topic to discuss. In this study, the effect of adding bilge keel pair to 2 and 3 pairs of bilge keel on ship’s rolling motions was studied so that the ship’s performance becomes more optimal. The patrol boat model that had been designed was studied using integrated BEM (Boundary Element Method) to obtain each model’s rolling value. This study concluded that the addition of installed bilge keel pairs increased RMS rolling by 11-50% on low speed, but it reduced 7-28% RMS rolling at high speed.Keywords:  Bilge Keel, Patrol boats, Ship motions, Rolling.
