Abstract

Selatbaru Indah Beach is one of the tourist beaches in Bengkalis Regency, located in Bantan District, 22 km from Bengkalis City. This beach has sheet pile construction using geobag materials and Armor rock. Currently experiencing changes in the plaster structure with the slope of the previous structure was 1:3 changed to 1:5. This research is to find out which slope of the structure is more efficient in reducing run up and overtopping in the Selatbaru tourist beach area. This research method uses field observation methods with surveys of building conditions and wave and tidal data from other sources. Wave height data is 0.5 m with HWL 2.45 m, LWL 0.03 m, wave period is 2.7 seconds, freeboard height is 0.45 m now and 0.25 m after a sea level rise of 0.2 m from present condiition. The results of the analysis for the slope of 1:3 sheet plaster, the value of Irribaren is 1.58 and Ru/H is 1.7, so the run up value is 0.85 m and overtopping occurs, for the slope of sheet pile 1:5 the value of Irribaren is 1.58 and Ru/H is 0.95, so the run up value is 0.2 m and there is no overtopping. The slope of 1:5 is able to reduce run up from 0.85 m to 0.2 m by 76%. This is because the sloping side of the sheet pile towards the sea will reduce wave run up. Keywords: Seawall, run up, slope structure, overtopping

Abstract

Located in Selatbaru Village, about 25 km from the centre of Bengkalis City, Selatbaru beach has become afavourite destination for tourists who want to enjoy the beauty of nature while engaging in outdoor activities. At thatbeach, a stepped-type seawall has been constructed to prevent erosion and make it easier for visitors to enjoy the beach,such as going down to and coming up from the beach. The current situation is during high tide and strong winds, wavesrun up the top of the seawall, causing seawater to surge onto the land. This research will conduct experiments by creatinga prototype based on field survey data and laboratory scale, including the seawall dimensions, water level, and waveheight, with a scale ratio of 1:10. The experimental scenarios to be conducted in the laboratory a. Existing seawall slopeof 1:3 with embankment, b. Changing the seawall slope to 1:5, and c. Changing the seawall slope to 1:5 withembankment. The irregular wave height to be simulated in the laboratory is 0.8 meters. The experiment will be conductedto observe the response of the seawall structure to incoming waves and the over topping occurring on the seawallstructure. The results shows that the alternative of adding an embankment and using a 1:3 seawall slope, has already beenable to reduce over topping volume 40,74 %. For the second scenario, the over topping volume decreased by 77.78 %,while the third scenario reduced over topping by 100 %. The best scenario is the third with slope to 1:5 and added of embankment that will decrease volume overtopping up to 100 %.

Abstract

Jalan Pangkalan Nyirih - Kadur merupakan salah satu jalan yang berada Kecamatan Rupat Kabupaten Bengkalis, Jalan Pangkalan Nyirih - Kadur saat ini sudah ditimbun dengan base B, Namun saat ini kondisinya sudah mengalami kerusakan berupa lubang lubang besar karena penimbunan dilakukan beberapa tahun yang lalu. Maka dari itu diperlukan perencanaan tebal perkerasan dan rencana anggaran biaya. Metode yang digunakan untuk menghitung tebal perkerasan adalah Manual Desain Perkerasan 2017, sedangkan untuk anggaran biaya menggunakan HSP bengkalis tahun 2022. Dengan umur rencana 40 tahun dan nilai CBR lapangan 7.8%, maka diperoleh hasil lapis pondasi kelas B setebal 300 mm, lapis pondasi kelas A setebal 125 mm dan perkerasan kaku setebal 200 mm mutu beton K-300 kg/cm². Direncanakan menggunakan Beton Bersambung Dengan Tulangan (BBDT) anyaman welded wiremesh, dan menggunakan Dudukan tie bar yang digunakan adalah baja tulangan polos, diperoleh hasil rencana anggaran biaya sebesar Rp.19.117.704.648,81

Abstract

Jalan memegang peranan penting dalam mendukung mobilitas dan pertumbuhan ekonomi. Namun, kerusakan jalan seperti retak, lubang, dan deformasi ringan dapat mengganggu kenyamanan dan keselamatan pengguna. Penelitian ini menganalisis kondisi perkerasan lentur di ruas Jalan Pelintung (Batas Kab. Bengkalis) – Sepahat – Sei. Pakning sepanjang 29,97 km menggunakan metode Bina Marga 1990, RCS, RCI, IRI, SDI, dan aplikasi RoadLab Pro. Hasil menunjukkan seluruh segmen memiliki Urutan Prioritas (UP) > 7, sehingga direkomendasikan untuk pemeliharaan rutin. Nilai IRI yang diperoleh dari RoadLab Pro dikonversi menjadi RCI dan dibandingkan dengan nilai RCI hasil perhitungan manual. RoadLab Pro menghasilkan nilai RCI rata-rata sebesar 95,7% (kondisi sangat baik), lebih tinggi dibandingkan metode manual sebesar 80,7%, dengan selisih 0,1–2,0 akibat gangguan jaringan. Meskipun terdapat perbedaan, hasil yang tidak terlalu signifikan dan menunjukkan bahwa aplikasi ini efektif dalam mempercepat proses evaluasi kondisi jalan. Penggunaan teknologi digital seperti RoadLab Pro dapat menjadi alternatif yang efisien dalam survei kerusakan jalan. Penelitian selanjutnya disarankan dilakukan di lokasi dengan kualitas jaringan yang lebih baik untuk meningkatkan akurasi pengambilan data secara digital.
