Abstract

ABSTRAKSungai Pemali berada di daerah aliran sungai (DAS) Pemali seluas 1344,27 km2 dengan panjang sungan 125,5 km dan secara rinci curah hujan setengah bulanan berkisar antara 16 mm sampai dengan 447 mm, misim kemarau berlangsung antara bulan Mei sampai dengan Oktober dan musim penghujan antara bulan November sampai dengan bulan April.Tujuan penelitian ini adalah melakukan analisis perhitungan untuk mendapatkan besarnya potensi air dengan data sekunder yang tersedia. Secara kuantitas, permasalahan air bagi pertanian terutama di lahan kering adalah pasokan air tergantung dari sebaran curah hujan di sepanjang tahun, yang sebenarnya tidak merata sekalipun di musim hujan. Oleh karena itu, diperlukan teknologi tepat guna, murah dan dapat diaplikasikan untuk mengatur ketersediaan air agar dapat memenuhi kebutuhan air.Peranan saluran irigasi membantu dalam memenuhi kebutuhan air untuk tanaman padi maupun kebutuhan air untuk petak sawah salah satunya daerah irigasi Brebes dengan luas 23.568 Ha. Hal initerbukti dengan adanya sauran irigasi sehingga kebutuhan air untuk tanaman padi tercukupi dengan baik.Kata Kunci : Analisis, Hidrologi, Potensi Air ABSTRACTPemali River is located in Pemali river basin (DAS) area of 1344.27 km2 with a widening length of 125.5 km and in detail semi-monthly rainfall ranges from 16 mm to 447 mm, drying missiles run from May to October and season the rain between November and April.The purpose of this study is to perform calculation analysis to obtain the amount of potential water with secondary data available. In quantity, the water problem for agriculture, especially in dry land is the water supply depends on the distribution of rainfall throughout the year, which is not evenly distributed even in the rainy season. Therefore, appropriate, inexpensive and applicable technology is needed to regulate the availability of water in order to meet water needs.The role of irrigation channels helps in meeting the water needs for rice crops and water needs for rice fields, one of which is Brebes irrigation area with an area of 23,568 Ha. This is proven with the existence of irrigation sauran so that the water needs for rice crops is well suited.Keywords : Analysis, Hydrology, Water Potency

Abstract

This study analyzed the irrigation water needs in the western region of Indramayu, Indonesia, using the KP-01 method and the CROPWAT 8.0 application. The main focus of this study is the importance of effective water management in agriculture, especially in the midst of increasing demand and climate change. Climatological data, soil characteristics, and crop information are collected to estimate irrigation needs. The results show that CROPWAT 8.0 is superior to the KP-01 method in terms of resource use efficiency, ease of use, flexibility, and reproducibility of results. CROPWAT 8.0 recorded the highest irrigation needs in January, while the KP-01 method recorded the highest in September. Although KP-01 provides more accurate and regulatory compliant water demand figures, CROPWAT 8.0 is more efficient for large-scale data processing. Daily evapotranspiration (ETo) variations ranged from 2.6 mm/day to 4.0 mm/day, with the highest ETo occurring in December. The highest irrigation water demand was recorded in September (1,850 ltr/second/ha) and the lowest in June (0,199 ltr/second/ha). The ETo calculation using CROPWAT shows an annual average value of 4.84 mm/day, with fluctuations affected by temperature, humidity, and solar radiation. The findings aim to optimize water resource management and increase agricultural productivity in the region. The selection of the right method depends on the specific needs and applicable regulations.

Abstract

Poor road infrastructure conditions have a significant impact on transportation efficiency, user safety, and logistics costs, especially in areas with tropical climates and heavy vehicle traffic such as in West Java. This study aims to evaluate the condition of road pavement on the Jangga–Cikamurang Road section in Indramayu Regency using the Pavement Condition Index (PCI) method. The survey was conducted visually along 1 kilometer of road, which was divided into 10 segments of 100 meters each. Observations included identification of the type of damage, severity, and extent of damage in each segment. The results of the study showed that the most dominant types of damage were alligator cracking (42.47%) and depression (33.63%) with high severity. The PCI values obtained varied between 6 and 78, with 60% of segments categorized as poor to failed, and only 10% in satisfactory condition. These findings indicate that most road sections are in unserviceable conditions and require structural handling. Based on the PCI value classification, reconstruction actions are recommended for segments with PCI < 55, overlay and structural maintenance for PCI 55–70, and preventive maintenance for PCI > 70. This study confirms the importance of implementing PCI as a technical decision-making tool in sustainable road maintenance planning.

Abstract

This study discusses the comparison of cost and time efficiency between precast and conventional concrete systems in the structural work of building construction. The research adopts a quantitative comparative approach on two segments of the Sartikaasih Bhayangkara Hospital project in Bandung. The BoQ calculation results show that the precast system incurred lower total costs, amounting to IDR 17.6 billion (A1) and IDR 12.74 billion (A2), compared to the conventional system with IDR 19.86 billion (A1) and IDR 14.29 billion (A2). In terms of time, the precast system demonstrated significant efficiency, with savings of 65.02% on A1 and 21.43% on (A2). This efficiency contributes to the reduction of indirect costs and the risk of project delays. These findings indicate that the precast system can serve as a more economical and efficient alternative for building construction projects.

Abstract

The selection of structural materials plays a crucial role in determining cost efficiency and construction time in building construction projects. This study aims to analyze and compare the construction costs of reinforced concrete and steel structures in the construction of the Modern Islamic Boarding School An-Nizam in Purwokerto. A quantitative comparative method was used by calculating the volume of work, construction cost estimates (RAB), and project duration for both types of structures. The analysis focused on main structural elements such as columns and beams, based on detailed drawings, unit price standards, and project technical data. Based on the calculations and analysis of this project, it can be concluded that the total construction cost for the reinforced concrete structure is Rp 8,983,363,148.58. Meanwhile, the total construction cost for the steel structure is Rp 8,445,489,989.60. The duration of the steel construction work is 19-20 weeks, and the duration of the concrete structure construction work is 25-30 weeks. Therefore, it can be concluded that from this case study, the total cost required for concrete structure construction is cheaper than steel structure construction by a difference of Rp 537,873,158.98. However, the duration of steel structure construction is faster than concrete construction, with a difference of 6-10 weeks.

Abstract

The rapid growth of private vehicles in urban areas has caused various problems such as traffic congestion, increased air pollution, excessive fuel consumption, and decreased quality of life. The urgency of this research lies in the need for strategic solutions to reduce the use of private vehicles in the city center, one of which is through the construction of Park and Ride (PnR) facilities integrated with public transportation. The purpose of this research is to determine the strategic location of PnR facilities in Cirebon City to support a more sustainable urban transportation system. This research uses the Analytical Hierarchy Process (AHP) method involving ten main criteria, including parking lot capacity, supporting facilities, ease of access, transportation integration, intermodal connectivity, and development costs. Data was obtained through expert surveys and secondary data from relevant agencies. The results showed that the alun-alun kejaksan area is the most optimal location for the development of PnR facilities, followed by Kejaksan Station, Prujakan Station, and Harjamukti Terminal. This location is superior in terms of accessibility, land capacity, transportation mode integration, and proximity to community activity centers. These findings are expected to be a reference in planning and policy making for the development of urban transportation systems in Cirebon City.
