Publisher : Universitas Pandanaran

Dusun Karangmangu di Desa Cibalung adalah salah satu dari dusun yang terpencil lokasinya dari dusun lainnya. Karena terpencil, maka prasarana perhubungan sangat dibutuhkan sekali. Jalan Jambuluwuk-Karangmangu adalah satu-satunya akses jalan untuk menuju ke desa maupun ke kecamatan. Namun jalan tersebut mengalami kerusakan parah sepanjang 250 m1 pada lokasi Jambuluwuk atau berada pada Dusun Cibalung. Jalan tersebut diusulkan pada PPK TA. 2003 dan dapat didanai. Kegiatan dapat diselesaikan sampai targetnya, namun sebelum serah terima, terjadi musibah runtuhnya jembatan (di luar target PPK) dan ada intervensi negatif dari kepala desa dalam pengelolaan dana TPK. Dengan semangat tranparansi dan semangat dukungan untuk membangun, kegiatan tersebut mampu diselesaikan dengan baik bahkan mampu mengembangkan.Kata kunci: pembangunan, Dusun Karangmangu, terisolir

In Indonesia, there are many sources of water. They can be ground water, rivers or seas which are certainly not easy to process these resources. Many problems have to be solved in processing these resources, such as flooding and "rob" problems in the Demak district. When dry season comes, how can we provide raw water and pure water for irrigation and other problems? One of the right solutions is to make a rubber weir that contains water. Normally, weir contains wind but this study tries to use different methods of filling weir by using water to make it easier and more practical in the treatment. Identifying problems such as alternative flood and rob handling is intended to unravel the problems in traffic congestion, submerged settlements and industrial estates, and analyzes the stability of the flow that occurs in the water-filled rubber weir model. The formulation of the problem with the model of water-filled rubber weir must be followed by the experimental system conducted in the Lab Faculty of Engineering UNISSULA Semarang. Therefore, the main problems studied in this research are the experiment of the waterfilled rubber weir, the hydraulic effectiveness of the water-filled rubber weir, and stability analysis of numerical models of the water-filled rubber weir. The purposes of this study are analyzing the hydraulic effectiveness of water-filled rubber weir with SOBEK application, analyzing the characteristics of the water-filled rubber weir to obtain a good weir material based on appropriate technology, and conducting a stability analysis of the flow occurring in the water-filled rubber weir model, prototype simulation of water-filled rubber weir.

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.

Water is a fundamental necessity that must be utilized wisely. This study was conducted in Damarkasian Village, located at the foot of Mount Sindoro and characterized by its hilly terrain. The village has a very limited supply of clean water, forcing residents to rely on a neighboring village for their water needs. Although there is a water distribution system in place, only wealthier residents can afford to build their own networks, while those less fortunate must rely on public facilities along the roadside. To address the uneven water distribution, a well-planned clean water distribution system based on gravity flow is essential. Field data collected includes spring water discharge, water quality, distance, and elevation, as well as population data from official statistics. Water discharge was measured using the volumetric method, and elevation and distance were recorded using the Q-GIS application. Network evaluation, conducted using EPANET 2.0 software, indicated a water discharge rate of 12.2 liters per second. To meet the village's water needs through 2037, a discharge rate of 10.57 liters per second is required. A total of 39 service tanks and appropriately sized PVC pipes are planned without the need for pumps, reducing costs. The total budget is estimated at IDR 1.4 billion, with a tariff of IDR 1,300/m³, cheaper than the PDAM rate.PENERAPAN TEKNOLOGI EPANET DALAM RANCANGAN SISTEM AIR BERSIH DI DESA DAMARKASIANAir adalah kebutuhan mendasar yang harus dimanfaatkan secara bijak. Penelitian ini dilakukan di Desa Damarkasian, yang terletak di kaki Gunung Sindoro dan memiliki kontur perbukitan. Sumber air bersih di desa ini sangat terbatas, sehingga penduduk bergantung pada desa tetangga untuk pasokan air. Meskipun ada distribusi air, hanya masyarakat yang mampu yang dapat membangun jaringan sendiri, sementara warga kurang mampu menggunakan fasilitas umum di pinggir jalan. Untuk mengatasi masalah distribusi air yang belum merata, diperlukan perencanaan sistem distribusi air bersih dengan sistem gravitasi. Data lapangan yang dikumpulkan mencakup debit mata air, kualitas air, jarak, dan elevasi, serta data penduduk dari badan statistik. Debit air diukur dengan metode volumetrik, dan elevasi serta jarak dengan aplikasi Q-GIS. Evaluasi jaringan menggunakan software EPANET 2.0 menunjukkan debit air sebesar 12,2 lt/detik. Untuk memenuhi kebutuhan penduduk hingga 2037, diperlukan debit 10,57 lt/detik. Sebanyak 39 bak pelayanan dan pipa PVC dengan diameter yang sesuai direncanakan tanpa pompa, yang menghemat biaya. Total anggaran sebesar Rp. 1,4 miliar, dengan tarif Rp. 1.300/m3, lebih murah dari PDAM.
