Abstract

Sungai Pedes mempunyai bentuk tebing yang sangat curam, kondisi ini sangat mudah mengalami longsor apabila pada bagian bawah tebing mengalami gerusan/erosi. Sungai Pedes yang masih aktif bermeander juga menyebabkan adanya perubahan alur sungai dari tahun ke tahun. Hal ini menunjukan bahwa terjadi gerusan di sepanjang alur Sungai Pedes. Untuk menanggulangi terjadinya gerusan terutama pada Sungai Pedes ruas P14-P40, maka perlu  direncanakan perbaikan sungai. Analisis hidrologi dengan menggunakan software HEC-HMS didapatkan debit rencana Q20th = 274,6 m3/det. Analisis hidrolika menggunakan software HEC-RAS didapatkan kedalaman air 2,2 m. Berdasarkan kemiringan dasar sebesar 0,0127 dan kedalaman air 2,2 m, didapatkan kecepatan kritis sebesar 0,532 m/det melebihi kecepatan kritis yang diijinkan 0,018 m/det. Untuk mengurangi kecepatan kritis perlu dilakukan pengurangan kemiringan dasar, didapat nilai kemiringan rencana sebesar 0,000014 dan diperoleh hasil bahwa Sungai Pedes ruas P14-P40 tidak terjadi gerusan, namun pada Sta Hu 0+25 – Hi 0+25 masih terjadi gerusan. Untuk menanggulangi gerusan yang terjadi, direncanakan bangunan berupa check dam 1 pada Sta Hu 0+50 dengan tinggi 3,6 m, check dam 2 pada Sta Hi 4 dengan tinggi 5,2 m dan bronjong pada Sta Hu 0+25 – Hi 0+25 dengan tinggi 5 m. Perencanaan teknis keseluruhan direncanakan sebesar Rp. 9.491.000.000,00 dengan durasi pekerjaan 49 minggu.

Abstract

Traffic accidents are a serious problem that requires treatment given the magnitude of the resulting losses. For this study needs to be done is conducting an analysis of the data kecelakaaan existing traffic. This final project took place Unggaran Highway Toll - Bawen in Semarang Regency. The roads are arterial roads are congested with traffic. This is due to the road connecting Semarang as one of the major cities in Central Java with the surrounding areas, for example : Solo, Magelang and Yogyakarta. The purpose of this study was to identify the location and cause of road accidents in order to provide suggestions efforts to reduce accidents will happen. Analysis of the data by the author to determine the relationship between variables that affect the number of accidents using SPSS computer program, while for determining the location of the accident - prone (blackspot), using statistical techniques of traffic control. Incidence of traffic accidents are caused by several factors, namely human (driver), environment, vehicle and road. From the data analysis, humans are the main factors causing accidents (66.89%). Driver is less anticipated driver behavior most often cause accidents (72.45%). The most frequent type of accident happens is hit the front - front (50.85%), with motorcycles (53.78%) as the most frequent vehicles involved. The most frequent time of an accident is at 12:00 to 18:00 (31.74%), and professional drivers who are often involved in accidents are employees / private (61.86%). Location blackspots on roads Unggaran - Bawen have 6, which Pertigaan Citroen (40 events), Pertigaan Weak Abang (35) events, Pertigaan Ngobo ( 31 events), Home of PT Sosro = (27 events), Home of PT Apac Inti Corpora (32 events), Pertigaan Bawen (36 events) Accident that occurred on Jalan Raya Unggaran - Bawen in the next 5 years (2008-2012) is as much 293 events and 201 events which occurred at the point - titk blackspot, while the rest occurred with locations spread along roads Unggaran - Bawen. Details of the total casualties are 444 people minor injuries (72.55%), 78 people were seriously injured (12.75%), and 90 people died (14.71%). Based on the data and the field conditions we have several recommendations to reduce the rate of accidents on roads Unggaran - Bawen ie : need to be made to the guardrail or median openings at the intersection with the aim of anticipating the next hit-and - forward, need to manufacture lap behind (U - Turn) on roads Unggaran - Bawen to facilitate vehicle that will turn it over, the need for enlargement of the fingers - fingers curved corner at the intersection, thereby reducing the frontal crash and will expand the driver's view when cornering at intersections, the need for the provision of counseling about driving safety, the need for the creation of a study conducted motorcycle lanes on Jalan Raya Unggaran-Bawen.

Abstract

ABSTRAK Dalam siklus hidrologi terdapat sungai dan saluran drainase yang berfungsi untuk mengalirkan air dari daerah tangkapan sampai ke laut. Pada lokasi studi yang berada di kawasan Arso terdapat dua sungai dan dua saluran yaitu Sungai Skanto, Sungai Tami, saluran drainase Arso Barat, dan saluran drainase Arso Timur. Kondisi saat ini, debit di Sungai Skanto dan Sungai Tami cukup besar sehingga terjadi backwater. Dengan adanya backwater di Sungai Skanto dan Sungai Tami maka aliran air limpasan dari drainase Arso Barat dan Arso Timur tidak bisa mengalir ke Sungai Skanto dan Sungai Tami yang menyebabkan melimpasnya air ke wilayah Arso. Dalam pengendalian banjir di kawasan Arso, secara prinsip air limpasan dari kawasan Arso di tampung sementara di kolam retensi. Saat banjir di Sungai Skanto dan Sungai Tami surut, air di kolam retensi dapat dialirkan keluar. Perencanaan sistem kolam retensi Arso dihitung menggunakan debit banjir dengan periode ulang 10 tahun. Dari hasil pengolahan data curah hujan periode ulang 10 tahun dengan menggunakan metode Nakayasu didapat Qrencana sebesar 246,20m3/detik untuk saluran drainase Arso Barat dan 17,282 m3/detik untuk saluran drainase Arso Timur. Dari hasil pemeriksaan saluran eksisting didapatkan bahwa saluran drainase Arso Barat bahwa saluran harus dinormalisasi. Dengan menggunakan metode flood routing Q periode ulang 10 tahun didapat volume air yang tertampung di kolam retensi sebesar 3.253.796 m3.

Abstract

Gayamsari District Area of Semarang is one of the flooded area. The causes of flooding is local rainfall that occurred in the village Gayamsari, Pandean Lamper, Siwalan and Sambirejo which is a sub-system of the East Flood Canal, where the channel capacity in the area can not accommodate the flow of water passing through the channel. Limited drainage capacity caused by the blockage of garbage and sediment that makes the water can not flow when it rains. This causes the drainage channel over capacity when it rains with great intensity and in a rather long time, which can result in a puddle with a depth of between 20-50 cm for ± 1-5 hours. To overcome this done drainage planning in order to cope with floods and inundation in the area. The initial steps of planning a drainage cover primary and secondary data collection, planning drainage used 14 years of rainfall data, topographic maps and the existing drainage system. In planning, hydrological analysis to seek the discharge plan with EPA SWMM program. Obtained flood discharge plan with a return period of 5 years on each subcatchment ranged from 0.24 to 3.81 m3 / sec. Furthermore, to determine the effectiveness of the existing channel cross section is modeled with HEC-RAS program. Planned cross-section with a steady flow conditions. The results of calculations using the program shows a cross section in the downstream Gajah Raya Street and Soekarno-Hatta Street can not accommodate discharge plan. Handling is done by increasing capacity of the drainage channel and making the detention basin.

Abstract

Telogorejo Hospital is a hospital located in the city center (CBD) with a lot of activity around it, so the traffic is congested. Currently, the private hospital is under developing with targeted towards an international hospital. Therefore it is important to assess the impact of traffic caused by the development. At the beginning of the calculation, we evaluated the performance of intersections and roads around the site development. Then proceed with the calculation of estimated towing vehicle movement and percentage growth. Both were included in the analysis of the performance of intersections and roads no hotspot at the post opening. The method of analysis used is MKJI (Indonesia Jalan Capacity Manual) 1997 dedicated to vehicle traffic. From the analysis it is known that the existing conditions in 2012 was the performance of intersections and roads hotspot is still good. It can be seen from the value of DS was still below 0.75, the speed on the road is still higher than 20 kilometer per-hour, and delay at the no hotspot intersection is still less than 30 seconds / smp. At the time of its unveiling in 2014, there is a condition on the Anggrek intersection at workingday at morning peak hours its DS value greater than 0.75 is 0.88. While the results of the analysis of the long-term 5 years after opening in 2019, Anggrek intersection performance became much worse that is the highest DS value of 1,04, but the intersection Theresiana still good. Technical solutions to address the intersection of Anggrek at the opening is to provide non-permanent median on the major approach of limiting the right turn movement on each approach and also a straight movement in South Seroja approach. The median was installed as weekday morning peak hour. In the segment of Road Anggrek is made diversion parking from the road. While the solution to the current problems five years after opening is to install a non-permanent median at the Anggrek  intersection so there is no right turn movement on each approach and also the straight movement in South Seroja  approach. It also made a major widening in line at 1 m on each side and minor lane widening at 0.5 m in each side. Simpang Theresiana good condition at present, at the opening, as well as five years after opening no problems whatsoever so there is no meaningful treatment. It's just that every Sunday morning there is a market there for people who can not be predicted future conditions, thus requiring further research.

Abstract

Waduk Wonogiri terletak di bagian selatan Kabupaten Wonogiri. Sepanjang pengoperasiannya waduk ini mengalami sedimentasi  3,1 juta m3/tahun, aliran sedimen terbesar disumbang oleh Daerah Aliran Sungai (DAS) Keduang. Diperlukan upaya untuk mengurangi sedimentasi, antara lain dengan membuat saluran bypass agar aliran dengan konsentrasi sedimen yang tinggi dapat dialihkan sebelum masuk ke waduk. Perencanaan ini bertujuan untuk menentukan debit operasional, struktur dan dimensi penampang saluran bypass Sungai Keduang hingga rencana anggaran pembangunan. Metode yang digunakan dalam perencanaan ini adalah dengan melakukan analisis hidrologi melalui pendekatan konsep debit dominan dan angkutan sedimen sehingga dapat diketahui besarnya debit, waktu pelepasan, dan tingkat efisiensi. Berdasarkan hasil analisis yang dilakukan, volume air yang dilepas melalui saluran bypass rata-rata sebesar 482.044.742 m3/tahun, dan batasan debit operasional saluran bypass sebesar 10-30 m3/s. Dengan batasan tersebut dihasilkan tingkat efisiensi saluran bypass rata-rata sebesar 29,36%. Pengoperasian saluran bypass menggunakan pintu air tipe angkat dan pintu klep otomatis, dengan perkuatan sisi mengggunakan dinding penahan pasangan batu. Perkiraan nilai biaya pembangunan saluran bypass sebesar Rp 217.540.837.000 (dua ratus tujuh belas milyar lima ratus empat puluh juta delapan ratus tiga puluh tujuh ribu rupiah) dengan durasi pelaksanaan pekerjaan selama 37 minggu.

Abstract

Optimalization of rural public transit is needed to improve people’s prosperity, especially for those who live in remote rural area. Rural public infrastructure nowadays hasn’t been optimized properly by the government yet, proven by a few number of region which already has urged rural transportation infrastructure. This research aims to select the location of rural public transit system development in Central Java according to priorities. This research focuses on the region which has had the interregion rural public transit system route already. The analysis of developing system of rural public transit defines the location priority by Analytical Hierarchy Process (AHP) method and recommends its road typical. To determine location priority uses Analytical Hierarchy Process (AHP) method. Determination of criteria based on the results of questionnaires distributed to the expert. The criteria are total area, the number of demand, population density, LQ index of rural public transit availability, the number of trip distribution, primary-food volume, the number of rural public transportation supply, and the number of vehicles-owner. Utility assessment is done by using secondary data. From these two steps, location priority will be determined. The last step is identified whether it is necessary or not to advance its road typical based on the Region Land Use Planning as mentioned in the valid regulation. The result shows that the most significant factor in determining the rural public transit system development is the number of demand which gets 25,7%. The result clearly shows that Brebes and Tegal has been admitted as the most priority region of rural public transit system development. Amongst of all the routes of interregion rural public transit, there are two routes which should be advanced its typical road: Boyolali-Sragen route and Sukoharjo-Boyolali route. The conclusion of this research is there is still a few of region on Central Java which already has the interregion rural public transit system route –only nine regions. The government should support another region to supply this route access.

Abstract

Electricity is a basic human need. Human activity will be disrupted if the availability of electrical energy is also affected. This condition is also currently being experienced by the people of Indonesia. There has been an energy crisis in some regions of Indonesia, particularly in Java - Bali where the area is the center of activity in Indonesia. This is indicated by the frequent occurrence of blackouts in rotation as in most cities in Indonesia. The crisis caused by an imbalance between  supply and demand of electricity usage. Meanwhile, the ability of the government, in this case the PLN in providing the electricity needs is very limited. Therefore, the government is encouraging private sectors and communities to participate in the production of alternative energy, one of which is the Mini Hydro Power Plant. Banyumas Regency has a potential river to build as Mini Hydro Power Plant. This mini hydro power plant will utilize the waterflow from the rivers. The electrical energy produced will be supplied to the Java – Bali interconnection network so that electricity supply can increase the Java – Bali capacity. In this  PLTMH  Logawa is planned to generate 616 kWh of power which can serve approximately 600 homes with the assumption that the usage of the power is about  900 watts per hours. It requires investment funds for the construction works amounting to Rp.25,265,787,700,-
