Abstract

Roads are transportation infrastructure whose needs in Indonesia continue to increase, along with the increasing number of vehicles. Road construction is a construction that receives traffic loads, therefore it is expected that a road pavement layer must have a strong pavement construction and be able to receive loads from traffic users. AC-WC (Black-top Concrete - Wearing Course) asphalt layer is a road pavement construction consisting of asphalt composition, coarse aggregate, fine aggregate and filler. Fillers in asphalt mixtures function to increase the binding power of AC-WC asphalt, so as to improve mixture stability and fillers can fill the voids between aggregate particles, filler commonly used is stone ash. This research will be conducted with the addition of broiler eggshell filler and porland cement in the Asphalt Concrete wearing Course (AC-WC) mixture. The research was conducted with an experimental method conducted in the Civil Engineering laboratory of Abdurrab University. The specification used in this study is Public Road Revision 2 Year 2018, The optimum asphalt content (KAO) used was 6.5%. Based on the results of the study, the largest marshall stability and melting value is found in the 100% cement filler variation, which is 1772.7 Kg and the value of flow value (melting) 3.77 mm while the largest marshall quotient (MQ) value is found in the 25% eggshell filler variation, 75% cement, which is 529.2 Kg/mm.

Abstract

Perencanaan Rencana Anggaran Biaya (RAB) merupakan tahapan penting dalam proyek konstruksi untuk menjamin ketepatan pengendalian biaya. Perbedaan metode analisis harga satuan dapat menghasilkan estimasi yang bervariasi dan memengaruhi pengambilan keputusan proyek. Penelitian ini bertujuan membandingkan estimasi biaya pekerjaan struktur menggunakan metode Analisa Harga Satuan Pekerjaan (AHSP) 2023, Standar Nasional Indonesia (SNI) 2008, dan Engineer Estimate. Metode penelitian yang digunakan adalah deskriptif kuantitatif dengan pendekatan studi kasus pada pembangunan Masjid Markaz Sunnah Nusantara Al-Hijrah di Kota Pekanbaru. Data yang digunakan berupa data sekunder meliputi AHSP 2023, SNI 2008, standar harga barang dan jasa Kota Pekanbaru tahun 2022, gambar kerja struktur, serta dokumen Engineer Estimate proyek. Hasil penelitian menunjukkan estimasi biaya metode AHSP 2023 sebesar Rp61.333.100.000, metode SNI 2008 sebesar Rp46.397.700.000, dan Engineer Estimate sebesar Rp47.292.800.000. Dibandingkan Engineer Estimate, metode AHSP 2023 menghasilkan estimasi lebih tinggi sekitar 29,69%, sedangkan SNI 2008 lebih rendah sekitar 1,89%, sehingga SNI 2008 merupakan metode yang paling mendekati Engineer Estimate pada studi kasus ini dan dapat menjadi acuan estimasi yang lebih ekonomis untuk pekerjaan struktur.   Cost Budget Planning (RAB) is a crucial stage in construction projects to ensure accurate cost control. Differences in unit price analysis methods may produce varying cost estimates and influence project decision-making. This study aims to compare structural work cost estimates using the 2023 Indonesian Unit Price Analysis Standard (AHSP 2023), the Indonesian National Standard (SNI 2008), and the Engineer Estimate method. A quantitative descriptive approach with a case study design was applied to the construction of the Markaz Sunnah Nusantara Al-Hijrah Mosque in Pekanbaru City. Secondary data were used, including AHSP 2023, SNI 2008, the 2022 standard prices for goods and services in Pekanbaru, structural drawings, and the project Engineer Estimate document. The results show that the estimated structural cost using AHSP 2023 is IDR 61,333,100,000, SNI 2008 is IDR 46,397,700,000, and the Engineer Estimate is IDR 47,292,800,000. Compared with the Engineer Estimate, AHSP 2023 produces an estimate about 29.69% higher, while SNI 2008 is about 1.89% lower. Therefore, SNI 2008 provides the closest estimate to the Engineer Estimate in this case study and may serve as a more economical reference for structural cost estimation.

Abstract

Sungai Kampar merupakan salah satu sungai utama di Provinsi Riau yang memiliki potensi banjir tinggi akibat luasnya daerah aliran sungai serta pengaruh kondisi hidrologi dan hidrolika. Penelitian ini bertujuan menganalisis debit banjir rencana dan mensimulasikan sebaran genangan menggunakan model HEC-RAS. Analisis hidrologi dilakukan berdasarkan data hujan maksimum tahunan periode 1970–2020 dari Stasiun Pasar Kampar. Uji distribusi menunjukkan bahwa distribusi Log Normal paling sesuai. Intensitas hujan dihitung dengan metode Mononobe dan didistribusikan menggunakan Alternate Block Method (ABM) untuk durasi 6 jam. Debit banjir rencana dihitung dengan metode hidrograf satuan Nakayasu untuk kala ulang 20 tahun, menghasilkan debit puncak sebesar 2185,18 m³/s. Simulasi hidrolika dilakukan dengan dua skenario, yaitu banjir tertinggi dan banjir tahunan. Hasil menunjukkan bahwa pada banjir tertinggi terjadi luapan signifikan pada STA 300–500 dengan kedalaman genangan maksimum 1,54 m di bantaran kanan dan 0,46 m di bantaran kiri. Pada banjir tahunan, genangan relatif terbatas dan tidak meluap di beberapa penampang. Hasil ini dapat menjadi dasar perencanaan pengendalian dan mitigasi risiko banjir di wilayah Sungai Kampar.   Kampar River is one of the main rivers in Riau Province with significant flood potential due to its large watershed and complex hydrological–hydraulic characteristics. This study aims to estimate the design flood discharge and simulate flood inundation using the HEC-RAS model. Hydrological analysis was conducted using annual maximum daily rainfall data from 1970–2020. Among the tested distributions, Log Normal was found to be the most suitable. Rainfall intensity was calculated using the Mononobe method and temporally distributed using the Alternate Block Method (ABM) for a 6-hour storm duration. The 20-year return period flood discharge was estimated using the Nakayasu synthetic unit hydrograph, resulting in a peak discharge of 2185.18 m³/s. Hydraulic simulations were performed under two scenarios: extreme flood and annual flood conditions. Results indicate significant overbank flooding during the extreme scenario, particularly between STA 300–500, with maximum inundation depths of 1.54 m on the right overbank and 0.46 m on the left. In contrast, annual flood conditions produce limited inundation without overtopping in several cross-sections. These findings provide a technical basis for flood control planning and risk mitigation in the Kampar River area.
