Drainage Jalan Raya Kelet - Bangsri, which is located in Jinggotan Village, Kembang District, Jepara Regency, is classified as an artificial drainage with a length of 725 meters. According to Muria News, “Jepara, 4/02/2020, it rained heavily from 10.30 to 15.00 on Jalan Raya Kembang - Bangsri, at that time there was a big flood which inundated the road as high as 30- 40 cm. Stagnant water occurs from the Flower Park to the Jinggotan bridge which is located to the south of SMA 1 Kembang. The flood disrupts the flow of local traffic, thereby inhibiting the speed of vehicles passing through it. "This research on the analysis of drainage capacity on Jalan Raya Kelet - Bangsri aims to determine the ability of drainage to drain wastewater, as well as to determine drainage capacity, and provide solutions to problems. the. In this previous research, what was done was to review the condition of the existing channel first, by collecting primary and secondary data then analyzing using HEC - RAS 5.0.7 software. Based on the problems that occurred on Jalan Raya Kelet - Bangsri drainage, it is necessary to analyze the drainage capacity, so that we can find out the solution for future planning. Hydrological analysis using HEC-RAS 5.0.7 software will make it easier to re-plan a drainage with a simulated channel condition. In the calculation analysis using the log distribution distribution log Pearson III because the value of Cs <1 from this method gets 2 years of rainfall 226.0757 mm, 5 years 285,6254 mm, 10 years 322,7451 mm so as to produce a planned flood discharge Q 2019 2.99 m3 / s, Q 2021 3.28 m3 / s, Q 2024 3.64 m3 / s, and Q 2029 4.04 m3 / s. whereas the HEC-RAS 5.07 software produces an average channel discharge of Q 2.43 m3 / s where Q Discharge> Q channel is stated that Q channel does not meet the requirements to drain flood discharge resulting in water runoff. For this reason, it is planned that U ditch with dimensions b = 1.2 m and h = 1.4 m with a manning roughness of 0.014 and a channel slope of 2.75%, from the analysis using HEC-RAS 5.0.7 software with U ditch dimensions b = 1.2 m and h = 1.4 m meet the requirements and are safe to accommodate flood discharge.

Basically, transportation is very necessary to facilitate all activities carried out by humans. The development of land transportation, such as the development of public transportation, is very rapid from year to year, this also requires development and progress in terminals as one of the road transportation infrastructure for loading and unloading people and/or goods, as is the case at Jetak Terminal, Kec. Kaliwungu District. Kudus is a type C passenger terminal, but along with the development of transportation, this terminal has changed its function to a type B terminal, so it is necessary to develop the terminal in terms of capacity and infrastructure. The method used in this research is to record the number plates of public transport entering, parking and leaving the terminal. Before conducting research, first ask for a research permit letter from the campus and the District Government. holy in this case BAPEDA Kab. Holy. The position of the Jetak Terminal in the existing road network system can be said to be quite strategic because it is on the main city route that connects Kaliwungu District with other areas, both in the western part of the city and with areas in the eastern part. Jetak Terminal has an area of 6.750 m², which consists of the building area and public transport parking area. Jetak Terminal currently has a parking area used by angkudes, microbuses, AKDP and motorbikes. Based on the results of calculations and survey results in the field, the need for parking space at the Jetak Terminal is currently unable to serve existing needs, where many microbuses are waiting for passengers outside the terminal. As a form of solving problems at the Jetak Terminal, it is possible to develop the terminal by optimizing the existing land around the terminal so that it can be utilized for the development of the Jetak Terminal.

Soft soil is caused by cohesion, a low internal friction angle and high compressibility. If not recognized and investigated it can cause instability and long-term decline that cannot be tolerated. One of the treatments that occurs in soft soil is light backfilling with foam mortar. The aim of this research is to carry out an analysis of the stability of embankments using lightweight materials at the location of bridge embankments in order to predict how much of an impact there will be in reducing settlement and increasing embankment stability. Analysis was carried out using the Finite Element Method with the help of the Plaxis 2D program. The method used in this research is descriptive qualitative, namely research by collecting primary and secondary data from the parameters and variables studied and then analyzing them to draw conclusions. In the results of the analysis using Plaxis Softwere using foam mortar treatment with an embankment slope of 1: 1.5, the results showed that the decline in 1 year was 4 cm (meeting the design criteria), the decline in 10 years was 2.8 cm (meeting the design criteria), apart from that the safety factor using foam mortar was also greater than the design criteria, which means the stability of the slope is safe.

Bencana banjir yang sering terjadi di Kecamatan Juwana, Kabupaten Pati, memerlukan upaya mitigasi yang efektif untuk mengurangi risiko dan dampaknya. Penelitian ini bertujuan untuk mengidentifikasi debit banjir rencana, menganalisis implementasi perangkat lunak HEC-RAS dalam pemodelan hidraulik, serta mengintegrasikan hasilnya dengan GIS untuk visualisasi zona rawan banjir. Analisis hidrologi dilakukan untuk menghitung debit banjir rencana menggunakan metode Rasional, Der Weduwen, Haspers, dan HSS Nakayasu. Simulasi hidraulik menggunakan HEC-RAS memberikan informasi mendalam mengenai profil muka air, kedalaman genangan, dan kecepatan aliran sungai pada berbagai titik sepanjang Sungai Silugonggo. Hasil penelitian menunjukkan debit banjir rencana mencapai puncak metode Rasional 2903,2192 m3/s, Der Weduwen 2291,861827 m3/s, Haspers 4433,007922 m3/s, dan Nakayasu 6114,1573 m3/s. Simulasi HEC-RAS berhasil memodelkan aliran sub-kritis (angka Froude < 1) dengan kedalaman genangan hingga 3 meter pada beberapa titik kritis. Integrasi dengan GIS menghasilkan peta risiko banjir yang memvisualisasikan area terdampak secara akurat, yang sangat berguna untuk perencanaan mitigasi bencana. Hasil integrasi ini menghasilkan peta risiko yang dapat digunakan sebagai acuan dalam penanggulangan bencana banjir. Metode yang lebih komperhesif yaitu Metode Nakayasu karena memiliki keunggulan dalam perhitungan hidrograf aliran dari waktu ke waktu. Penelitian ini menyimpulkan bahwa kombinasi HEC-RAS dan GIS merupakan pendekatan yang efektif dalam penanggulangan banjir, baik untuk identifikasi risiko maupun perencanaan infrastruktur pengendalian banjir. Penerapan hasil penelitian ini diharapkan dapat membantu pemerintah dan masyarakat dalam mengurangi dampak bencana banjir di Kecamatan Juwana.
