Abstract

Asphalt porous merupakan campuran bergradasi terbuka (open graded) dengan persentase agregat kasar yang besar, persentase agregat halus yang kecil, sehingga menyediakan rongga udara yang besar. Aspal porus merupakan inovasi untuk mengurangi genangan air di atas permukaan jalan. Aspal porus memiliki nilai stabilitas yang rendah namun memiliki nilai permeabilitas yang tinggi yang disebabkan oleh banyaknya rongga dalam campuran lapisan perkerasan sebagai sistem drainase. Aspal porus digunakan pada jalan yang memiliki lalu lintas yang rendah. Penelitian ini bertujuan untuk mengetahui nilai permeabilitas dan kekuatan material berdasarkan kriteria marshall dengan agregat yang bersumber dari Kakaskasen dan diatur di laboraturium sehingga memiliki parameter komposisi campuran sebagai bahan pengisi dan aspal penetrasi 60/70 sebagai bahan pengikat. Rancangan campuran berdasarkan komposisi agregat sesuai dengan persyaratan gradasi (Asphalt Concrete-Wearing Course) atau disingkat AC-WC dan dicari kadar aspal perkiraan dibuat benda uji marshall. Kadar aspal ditetapkan dulu menggunakan aspal penetrasi 60/70 sebagai bahan pengikat dan dibuat benda uji marshall dengan 5 variasi kadar batu blondos serta dilakukan pengujian untuk mendapatkan nilai permeabilitas dimana air di dalam tabung jatuh bebas kedalam mould yang berisi benda uji pada ketinggian tertentu sampai melewati rongga pada campuran. Hasil penelitian menunjukkan pada campuran aspal porus didapat kadar aspal terbaik 4.7% dengan kadar batu blondos sebesar 75% diperoleh nilai stabilitas 870,1 mm, flow 5,5 mm, VIM = 19,6 %, MQ = 203,4 kg/mm, semua besaran nilai kriteria marshall memenuhi nilai batas-batas spesifikasi. Hasil penelitian permeabilitas aspal porus didapat 0%; 0,48 cm/s , 25%; 0,81 cm/s, 50%; 0,60 cm/s, 75%; 0,34 cm/s, 100%; 0,63 cm/s, darisemua besaran nilai permeabilitas aspal yang memenuhi batas-batas kriteria spesifikasi adalah 75% campuran batu blondos. Berdasarkan penelitian tersebut diperoleh bahwa campuran aspal porus dengan menggunakan material bersumber dari Sungai Loning dengan menggunakan bahan pengikat aspal penetrasi 60/70 memiliki nilai stabilitas yang tinggi dan memiliki nilai permeabilitas yang tinggi tapi campuran tersebut masih layak digunakan pada kondisi jalan yang lalulintas rendah. Dengan demikian disarankan untuk campuran aspal porus melakukan penelitian yang lebih lagi dengan menggunakan sumber material yang berbeda serta bahan pengikatnya dan perlu diadakan penelitian lanjutan tentang kinerja marshall seiring dengan pengaruhnya kekuatan pada campuran perkerasan.

Abstract

The Pakijangan River Basin in Brebes Regency plays a critical role in supplying raw water for domestic, agricultural, and environmental needs. However, the absence of continuous streamflow records and increasing pressure on water resources pose significant challenges to effective management. This study aims to quantitatively estimate water allocation within the basin through a water balance approach. The methodology includes field surveys of existing conditions, analysis of water demand and availability, and water balance simulation using the RIBASIM (River Basin Simulation) model integrated with the Sacramento rainfall-runoff method. Rainfall data were obtained from two representative manual stations: Klampok and Slatri. Simulation results indicate that the Pakijangan Basin remains in surplus throughout the year, with dependable flow sufficient to meet all domestic and non-domestic water demands. With a distribution efficiency indicator (K factor) of 1, the basin even has the capacity to supply neighboring basins (Pemali River Basin) at a rate of 0.1 m³/s. These findings serve as a valuable foundation for sustainable, equitable, and efficient water resource planning and management in the region

Abstract

This study analyzes the application of time management using the crashing method on the Rehabilitation Project of the Disdikbudpora’s Hall Building in Semarang Regency. This project has an implementation period of 57 calendar days. To assess whether this duration could be optimized, the crashing method was applied to critical path activities by adding overtime work hours (1 to 3 hours/day). The research utilized a qualitative method with a quantitative approach, using primary data from field observations and secondary data such as schedules and weekly reports. Results showed that by adding 1, 2, and 3 hours of overtime, the project duration could be reduced to 54, 49, and 48 days, respectively. Cost analysis revealed that adding 2 hours of overtime provided the most optimal balance between shortened duration and additional labor costs, totaling IDR 58,556,562.50. This option offered a 5 day acceleration with a relatively small cost difference compared to 1 hour overtime. Therefore, adding 2 hours of overtime is considered the most efficient strategy for project acceleration.

Abstract

Many people still use private vehicles, making BRT's function as a solution to overcome congestion not optimally realized. The aims of this study were: 1) to determine the supporting and inhibiting factors for the Trans Semarang Bus Rapid Transit (BRT) service (Mangkang-Penggaron Corridor); 2) determine the effectiveness of the Trans Semarang Bus Rapid Transit (BRT) service (Mangkang-Penggaron Corridor). This research uses a quantitative approach. Data collection techniques are observation, interviews, and documentation. Data analysis technique is descriptive statistics. The research results show that the supporting factors for the BRT Trans Semarang service are the dominant flat and wide roads, so that large buses can be used. The inhibiting factors in BRT Trans Semarang services are the absence of a special lane for BRT Trans Semarang, so waiting times and fleet intervals are still very dependent on existing traffic conditions. How to overcome the inhibiting factors in BRT Trans Semarang services, namely planning a special route for the Jrakah intersection to the Pedurungan intersection with a length of 12.8 km to improve service and reduce passenger waiting time, as well as improve fleet intervals. While the effectiveness of BRT Trans Semarang service corridor I Mangkang-Penggaron obtained a total average percentage value of 84% in the very good category. The results of the one sample t-test that have been carried out obtained a sig 2-tailed value of 0.000 0.05, indicating that Ho was rejected, so the average value of the effectiveness of the Trans Semarang Bus Rapid Transit (BRT) service corridor I Mangkang-Penggaron is not the same with 80. It can be concluded that the effectiveness of the Trans Semarang Bus Rapid Transit (BRT) service (Mangkang-Penggaron Corridor) has been running effectively.
