Abstract

Penggunaan lahan parkir di badan jalan dapat menyebabkan terganggunya arus lalu intas. Salah satu ruas jalan di Kota Solok yang sebagian badan jalannya digunakan untuk parkir kendaraan adalah jalan Jenderal Sudirman. Ketika kendaraan melakukan manuver parkir akan membutuhkan waktu beberapa saat terutama ketika mengeluarkan kendaraan. Aktivitas ini dapat mengakibatkan tertundanya arus lalu lintas dan menimbulkan antrian kendaraan yang seterusnya dapat menyebabkan kemacetan lalu lintas. Penelitian ini bertujuan untuk mengetahui sejauh mana pengaruh manuver parkir badan jalan terhadap karakteristik lalu lintas. Metode yang digunakan adalah Uji Z Dua Arah, yang mana menghasilkan karakteristik parkir dan karakteristik lalu lintas yang dikelompokkan dalam dua kondisi lalu lintas yakni ketika arus lalu lintas lancar dan ketika arus lalu lintas terganggu. Karakteristik parkir yang diteliti berupa durasi manuver parkir ketika memasuki dan meninggalkan ruang parkir yang didasarkan pada faktor keberadaan kendaraan lain disisi ruang parkir, dan karakteristik lalu lintas berupa perhitungan volume kendaraan. Penelitian ini menghasilkan volume kendaraan ketika arus lalu lintas lancar dibandingkan dengan volume arus lalu lintas terganggu terjadi penurunan volume kendaraan dan dilakukan uji z dua arah didapatkan bahwa penurunan yang terjadi bersifat signifikan.

Abstract

Construction activities carried out in a self-managed manner experienced several problems or obstacles. One of the problems faced is, among others, design changes, changes in material prices, details of costs carried out in the field are not included in the Cost Budget Plan, materials often arrive late from the work plan, work method errors which cause repetitive work, loss of tools and materials at the project location and are still completing the work after the work contract is completed, so this project experiences delays in completing the work even though the work contract has been completed. This research aims to find out what factors influence delays in completion and to find out the dominant factors that influence delays in completion of the project Self-Managed Vocational High School Padang Center of Excellence. This research was analyzed using descriptive statistical analysis methods to determine the dominant factors that influence delays in completing self-managed work. From the results of data analysis using descriptive statistical analysis, it was obtained that there were changes or additions to work during project implementation with factor code (B3) as the dominant factor influencing delays in completing self-managed work.

Abstract

ainfall variability and extreme precipitation are critical environmental factors affecting the durability of reinforced concrete in coastal areas. This study aims to analyze the risk of reinforced concrete degradation in Padang City based on climate data from 2014 to 2024. The analysis was conducted by calculating mean monthly rainfall, standard deviation, coefficient of variation, and extreme thresholds (P90) to identify critical months with high wet exposure. Subsequently, concrete environmental classification according to SNI 2847:2019 was used to assess design implications on concrete quality and cover thickness. The results indicate that most months exhibit a coefficient of variation above 40%, with September–November identified as the most critical period for degradation risk. Extreme monthly rainfall during this period ranges from 589 to 769 mm, increasing wetting duration and wet–dry cycles, which may accelerate water penetration, carbonation, and reinforcement corrosion. These findings highlight the need for a durability-based design approach that adapts to local climatic conditions, particularly in specifying minimum concrete strength and cover thickness. This study provides a conceptual framework for evaluating reinforced concrete degradation risks in tropical coastal areas and offers guidance for designing more durable and sustainable structures.
