Abstract

Jalan Garuda Sakti is a provincial road that connects Pekanbaru City and Kampar Regency and serves as the boundary between inner-city and outer-city road segments. Road buildings and traffic equipment facilities are essential components in supporting road functionality, safety, and user comfort. This study aims to inventory the availability and identify the needs of road buildings and equipment facilities along both segments. A quantitative approach was employed through field surveys. The results indicate that no road buildings were available on either inner-city or outer-city segments. Of the nine types of road equipment facilities assessed, the inner-city segment was equipped with only two types, namely traffic signs and street lighting, while the outer-city segment had only traffic signs. The analysis of facility requirements shows that the inner-city segment requires roadside drainage channels, 17 street lighting units, 32 traffic signs, and two types of road markings. Meanwhile, the outer-city segment requires roadside drainage channels, 33 street lighting units, 28 traffic signs, and two types of road markings. Overall, the findings reveal that road buildings and equipment facilities are still inadequate in both segments, particularly in the outer-city area, highlighting the need for accelerated infrastructure development to improve traffic safety, comfort, and  mobility.

Abstract

The Kampar River, which flows through Rumbio Village, Kampar Regency, Riau Province, plays a vital role in the hydrological cycle and the sustainability of the surrounding ecosystem. However, the river is prone to flooding, especially during the rainy season, which necessitates technical interventions such as the construction of bank protection structures. This study aims to analyze the cross-sectional capacity of the river after the construction of the bank protection and to evaluate the potential increase in flow capacity through cross-section modification on the opposite side of the constructed bank protection. The methods used include field surveys with echosounder instruments to obtain depth and flow velocity data, calculation of cross-sectional area using the Mean Section method, and analysis of river discharge. The results showed that the highest recorded discharge was 19.47 m³/s, with a cross-sectional capacity of 51.69 m³/s after the construction of the bank protection. Following the cross-sectional modification, the maximum discharge increased to 49.54 m³/s, with a modified cross-sectional capacity of 157.98 m³/s. The study concludes that cross-sectional modification can serve as an effective solution to increase flow capacity and reduce the risk of flooding in the area surrounding the Kampar River in Rumbio Village

Abstract

This study aims to utilize extracted Spent Bleaching Earth (SBE) waste as an additive material in the production of clay bricks. SBE waste is a by-product of the palm oil bleaching process, which is abundantly available and has the potential to cause environmental pollution if not properly managed. The variations of SBE content used in this research were 0%, 30%, 40%, 50%, and 60% of the total clay weight. Tests were conducted on the physical appearance, dimensions, porosity, and compressive strength of the resulting bricks. The results showed that the addition of SBE waste affected the color and surface texture of the bricks, where higher SBE content tended to decrease visual quality. The volume shrinkage values ranged from 35.24% to 39.34%, which still met the requirements of SNI 15-2094-2000. However, the compressive strength test results indicated a decrease as the SBE percentage increased, with the highest value of 2.70 MPa and the lowest of 1.76 MPa, both below the minimum SNI standard of 5 MPa (Class III). Overall, SBE waste can be utilized up to a 30% variation as an alternative additive material in brick production, but further optimization is required by reducing the mixture variation to meet the structural strength standards.

Abstract

Construction labor productivity continues to be a global challenge, particularly in Indonesia, due to skilled labor shortages and resultant inefficiencies like idleness. Despite prior research on various construction tasks, a gap exists in understanding labor efficiency in modern light-gauge steel frame roof construction, which necessitates distinct work patterns. This study empirically investigates labor efficiency in light-gauge steel roof framing within a housing complex in Pekanbaru using the Work Sampling technique to ascertain the Labor Utilization Rate (LUR) and identify influencing factors. Findings indicate that design complexity significantly affects LUR, with Gable roofs (87.17%) demonstrating higher efficiency than Pyramid Hip roofs (84.36%). Team size and effective coordination are crucial, as Team C (three workers) achieved optimal output. Although essential contributory activities correlate positively with effective work, idle time, often due to fatigue or waiting, remains a challenge, particularly in complex tasks. This research provides critical insights and practical measures to enhance productivity in contemporary light-gauge steel roof construction.

Abstract

Roads are a vital infrastructure that supports the smoothness of social, economic, educational, and mobility activities of the community. This research aims to inventory the buildings and road facilities within and outside the city, focusing on Pasir Putih Road. The method used is a field survey with a quantitative approach to calculate the percentage of component availability. The analysis results show that in urban road sections, facilities such as parking lots, drainage systems, and roadside channels are not yet available, while street lighting facilities reach 80%, traffic signs 90%, and road markings 100%. In rural road sections, the availability of facilities tends to be lower. These findings indicate the need for accelerated development and procurement of road facilities, especially in rural areas, to enhance transportation safety and comfort.

Abstract

Tanah lempung diketahui memiliki kemampuan daya dukung yang rendah akibat karakteristik plastisitas tinggi serta perubahan volume yang signifikan terhadap variasi kadar air. Penelitian ini dilakukan untuk menganalisis sejauh mana penambahan pasir pantai dapat memengaruhi nilai California Bearing Ratio (CBR) pada tanah lempung di wilayah Kota Pekanbaru Upaya stabilisasi tanah dilakukan dengan mencampurkan pasir pantai Ketaping dalam beberapa variasi proporsi, yakni 0%, 10%, 20%, 30%, dan 40% dari berat total tanah kering. Pengujian  mencakup analisis sifat fisik dan mekanik tanah, seperti kadar air, berat jenis, batas Atterberg, uji pemadatan menggunakan metode Standard Proctor, serta uji CBR dalam kondisi soaked dan unsoaked. Hasil penelitian memperlihatkan bahwa penambahan pasir pantai secara umum mampu meningkatkan nilai CBR dan kepadatan tanah, sekaligus menurunkan nilai indeks plastisitas tanah lempung. Nilai CBR tertinggi ditemukan pada campuran pasir pantai sebesar 40%, yang menunjukkan peningkatan signifikan dibandingkan dengan tanah asli tanpa campuran. Berdasarkan temuan tersebut, pasir pantai dapat dipertimbangkan sebagai material alternatif lokal yang efisien, ekonomis, dan ramah lingkungan untuk tujuan stabilisasi tanah lempung, khususnya di kawasan pesisir seperti Kota Pekanbaru

Abstract

Provinsi Riau dengan lahan gambut yang cukup luas memiliki tantangan tersendiri dalam hal konstruksi khususnya konstruksi beton bertulang. Kandungan sulfatnya serta tingkat keasaman yang tinggi bisa berdampak buruk terhadap beton yang selanjutnya terhadap tulangannya. Oleh karena itu perlu perhatian tersendiri terhadap pembetonan di lahan gambut agar awet. Di sisi lain, fly ash sebagai limbah pembakaran batu bara pada tungku pembangkit listrik tenaga uap (PLTU) dinilai dapat meningkatkan kualitas beton dalam hal kekuatan, kekedapan air, ketahanan terhadap sulfat dan workability beton (Sofwan Hadi, 2000). Penelitian ini mengkaji bagaimana pengaruh substitusi sebagian semen dengan fly ash (abu terbang) terhadap kuat tekan beton yang terpapar sulfat. Fly ash dicampurkan sebanyak 30% dari berat semen. Dibuat juga sampel beton normal tanpa fly ash sebagai pembanding. Umur sampel divariasikan 7 hari, 14 hari, dan 28 hari. Setiap variasi dibuat 3 sampel yang direndam dalam air biasa & 3 sampel yang direndam dalam air sulfat untuk pendekatan simulasi paparan sulfat terhadap beton. Hasil penelitian menunjukkan bahwa paparan sulfat untuk hampir semua variasi perlakuan dapat mengurangi kekuatan beton baik pada beton normal maupun beton yang dicampur fly ash. Pada rendaman air biasa, kuat tekan beton beton yang dicampur fly ash lebih rendah dari beton normal. Pada rendaman air sulfat, substitusi fly ash berdampak positif terhadap kuat tekan beton pada umur-umur muda (7 hari & 14 hari) namun sebaliknya pada umur beton 28 hari.
