Floods are natural disasters that we often encounter during the rainy season. Apart from there are also tidal floods which are caused by global warming, this problem occurs in the city of Semarang, especially North Semarang, specifically the north coast of the Java Sea. Floods that occurred in 2021 in the city of Semarang include Starting from Genuk, Kaligawe, Satsiun Tawang, Tanjungmas, Karangayu, the flood disaster was caused by high rainfall, while tidal floods caused high tides and inundated roads and houses of residents on the north coast of Semarang city. To handle this problem, the government Currently we have made embankments, namely making embankments including the Sringin River which is equipped with a ponpa, Tenggang River, Babon River, Semarang River, Banger River, and others. These embankments are equipped with pumps so that when the water from upstream to downstream is high, the water is pumped. to the sea, the aim is to find out one of the annual discharges of the river, namely the Babon, and to find out the tamping capacity of the Babon River Longstorage. Apart from that, there is a method for handling tidal floods, namely using the Babon River Longstorage which is equipped with a pump, if there is high tide which inundates roads and houses. residents then the pump is turned on, whereas if the water recedes and does not inundate residential areas then the pump is turned off. Flood control analysis is calculated using the HEC-RAS program simulation using a return period of 50 years. Based on calculations using the HEC-HMS program. The flood discharge is 2,529 m3/sec. The high tide elevation is + 1.67 m, while the normal water level is -0.5 m.

Indonesia as an agricultural country is very interested in the availability of water to support the agricultural sector. One of the efforts to maximize agricultural production results is the utilization of water resources through proper and efficient management of water allocation. D.I Dolok has a large enough land area and of course requires quite a lot of water, so it is necessary to analyze the needs and availability regarding the control of irrigation water for optimal agricultural land. The purpose of this study is to determine the availability of water and the need for irrigation water in D.I Dolok. In this study using Dr. method. FJ. Mock, after we have calculated the data we got from the results of the field survey, the results obtained for the total discharge that can enter the Barang Weir is 51.058 m3/s, and for the amount of water availability in Barang Weir it increases in the rainy season and decreases in the dry season with the largest discharge occurred in January, namely 4,800 m3/sec and the smallest discharge occurred in August, namely 0,160 m3/sec. As for the irrigation water needs of the Barangay Dam, it was obtained 32,967 mÂ³/s with an area of 1296 Ha. Then for the calculation of the water balance by comparing the value of the mainstay discharge with the need for irrigation water with the selected cropping pattern, it can be concluded that the need for irrigation water can be fulfilled from the available mainstay discharge.

The Sambong River is located in Batang District, with relatively flat topography and proximity to the sea, making it prone to frequent flooding. As observed in the past three years, the largest flood occurred on January 2, 2023, at 11 points in Batang District, which indirectly caused significant losses to the surrounding community. Therefore, a study is needed to determine the rise in water levels and the flood discharge volume of the Sambong River and to analyze its ability to accommodate such discharge.In this study, the flood discharge analysis for the planned Sambong River was calculated using the Nakayasu HSS method, and the river flow conditions were simulated using the HEC-RAS program with the unsteady flow method. Several data and parameters were based on the existing conditions of the river, resulting in the following discharge values: Q5 319.787 mÂ³/s, Q10 381.146 mÂ³/s, Q25 460.936 mÂ³/s, Q50 521.907 mÂ³/s, and Q100 584.437 mÂ³/s. Based on the HEC-RAS simulation results from 66 STA observation points, it was found that for the Q5 and Q10 return periods, 88% of the STA locations flooded; for the Q25 return period, 91% of STA locations flooded; for the Q50 return period, 92% flooded; and for the Q100 return period, 95% of STA locations flooded, with varying flood heights. Therefore, it can be concluded that the Sambong River is no longer able to accommodate the planned flood discharge

Abstract. The Semarang toll road is the only toll road network in the city of Semarang at this time. The construction of toll roads aims to reduce congestion and improve travel time efficiency. In addition, the benefit of toll roads is that toll road users will benefit in the form of vehicle operational cost savings (BOK) and time compared to if they pass through non-toll roads. For alternative routes or non-toll roads, conventional roads can be chosen by motorists without passing through toll roads. This study aims to calculate vehicle operating costs (BOK), vehicle operating cost benefits (BKBOK) using the Pacific Consultant International (PCI) method as a limit to determine toll rates and analyze the comparison of Vehicle Operating Costs (BOK) on toll and non-toll roads. . Data collection techniques in this study used primary and secondary data collection techniques. The analysis was carried out using an interactive analysis model. The calculation of vehicle operating costs using the PCI method is taken from the lowest vehicle operating costs from various speed variations. For toll roads, the lowest vehicle operating costs occur at a speed of 60 km/hour with a total BOK of Rp. 6,803.54. Meanwhile, for non-toll roads, the lowest vehicle operating costs occur at a speed of 60 km/hour with a total BOK of Rp. 10,641.27. According to the analysis we have obtained, toll roads are cheaper than non-toll roads. For road users in the city of Semarang, it is recommended to use the Semarang section A toll road compared to non-toll roads, because vehicle operating costs are more efficient and have a much faster travel time.Keyword : BOK,BKBOK, speed, PCI, Toll Road
