Abstract

Ketika menggunakan beton bertulang dalam desain struktur, penting untuk memperhatikan kekuatan tekannya serta plastisitas dan deformasinya. Untuk meningkatkan kekuatan lentur dan daktilitasnya, bahan dengan kekuatan tarik tinggi ditambahkan. Salah satu contohnya adalah polimer serat karbon yang dikuatkan (CFRP), yang terbuat dari serat karbon yang disajikan sebagai fiberglass. Sebuah set tujuh balok beton bertulang, masing-masing dengan dimensi 12 x 20 cm dan panjang 200 cm, dibangun untuk menghitung jumlah kontribusi lapisan komposit fiberglass (CFRP) terhadap peningkatan kuat lentur dan daktilitas. Hasil pengujian menunjukkan bahwa lapisan CFRP yang lebih banyak membuat balok beton bertulang lebih mudah ditekuk. Kekuatan lentur balok RNSC 1A meningkat sebesar 6,65%, dan kekuatan lentur balok RNSC 2A meningkat sebesar 14,45%. Daktilitas balok RNSC 1B meningkat sebesar 12,71%, dan daktilitas balok RNSC 1B meningkat sebesar 17,13% menjadi 44,52%. Kekuatan fleksibel RNSC 1C meningkat sebesar 20,81% dan 11.89%. Kekuatan fleksibel RNSC 2B meningkat sebesar 17.92% dan 44.64%, sedangkan kekuatan fleksibel RNSC 2C meningkat sebesar 28.62% dan 37.64%.

Abstract

Jalan Baru Intersection on Jalan H.M. Noerdin Pandji, Palembang, is a signalized intersection connecting strategic areas such as shopping centers, residential zones, and access to Sultan Mahmud Badaruddin II Airport. High traffic volumes during peak hours often cause congestion, making it necessary to analyze the intersection’s performance. This study aims to assess the existing conditions and evaluate the intersection’s performance through an intersection inventory survey, classified turning movement count, and cycle time survey, supported by secondary data from relevant agencies. Analysis was conducted using peak hour traffic volume data (07:00–08:00 WIB) totaling 10,412 vehicles/hour. Results show the highest traffic volume on Jalan Pangeran Ayin at 3,662 pcu/hour and the lowest on Jalan Sako Baru at 1,375 pcu/hour. The average queue length reached 83.41 meters, with the longest queue at 120 meters. The average delay was 56.9 seconds/pcu, categorized as LOS E, indicating near-saturated flow with moderate to high delays. Overall, the intersection can still accommodate peak hour traffic, but performance is declining on certain approaches, particularly Jalan Pangeran Ayin and Jalan Sako Baru.Keywords: Intersection Performance, Traffic, LOS, Congestion, Palembang

Abstract

At present, paving blocks are widely used as building elements for making building construction, especially for yard pavement, parking lots, and environmental roads. Paving blocks are often used because they have good compressive strength properties, can withstand loads within certain limits, longer plan life, and are easy to install. In addition to these advantages, paving blocks are also better than other pavements in terms of economical maintenance, also in terms of the exterior of a building, and also when viewed in terms of environmental sustainability, as a water absorption system. Sawdust is the material (generally powder) that remains from burning wood. Generally, 6-10% of the mass of wood burned produces ash. From the results of research and discussion in the manufacture of paving blocks with wood dust ash additives planned to increase the compressive strength of paving blocks at the age of 28 days, it was found that the compressive strength of normal paving blocks with 0% wood dust ash was 16.08 MPa, while the compressive strength of paving blocks added with wood dust ash with a composition of 5%, 10%, and 15%, produced a compressive strength of 18.05 MPa; 15.24 MPa; 12.20 MPa;. The effect of sawdust ash on the addition of composition materials in the manufacture of paving blocks can increase the compressive strength of the paving block itself. The compressive strength of paving blocks increases after the addition of sawdust ash from the lowest sawdust ash of 0% to 5% ash only, while paving blocks with 10% and 15% sawdust ash experience a significant decrease in compressive strength value from normal sawdust ash. Keywords: Paving Block, Wood Powder Ash

Abstract

The increase in tyre production has led to an increase in tyre rubber waste, which is harmful to the environment. The use of rubber tyres as a substitute additive material in concrete or laston (AC-WC) is one way out to reduce unused rubber tyre waste. The purpose of this research is to determine the effect of the use of used rubber tyres on the Durability and Flexibility values of the laston layer mixture (AC-WC) and to determine the optimum mixture component value for Durability and Flexibility in the laston layer mixture (AC-WC). This research uses experimental methods, namely, quantitative research methods. In this study, researchers used a percentage of used tyre mixture of 1%, 2%, 3% and 4% of the weight of the test specimen and 0% as a normal mixture. The results of this study indicate that the flow value in the standard marshall percentage of used tyre rubber 1% and 2% meets the 2018 revised Bina Marga Specification 2 between 2-4 mm. While the percentage of used tyre rubber 3% and 4% does not meet the 2018 revised Bina Marga Specification 2 between 2-4 mm. Because the greater the percentage of used tyre rubber, the greater the flow value obtained. In Marshall Stability, it can be concluded that the remaining Marshall Stability value of the normal AC-WC asphalt mixture is 90.67%, this value meets the Bina Marga 2018 Revision 2 Specifications with standard Specifications 90%.  Keywords: laston layer mix (AC-WC), durability, flexibility, waste rubber tire, marshall
