Permasalahan kerusakan jalan yang terjadi, menunjukkan kinerja jalan yang ada saat ini tidak seperti yang diharapkan. Jalan dengan struktur perkerasan kaku mengalami kerusakan akibat beban lalu lintas yang melebihi kapasitas. Struktur perkerasan menjadi lemah atau berkurang kemampuannya untuk menerima beban sehingga perlu dilakukan penguatan struktur perkerasan kaku. Tujuan penelitian untuk mengetahui desain over slabbing yang meliputi kuat tekan, kuat lentur, modulus elastisits, permeabilitas dan susut beton sebagai material penguat perkerasan kaku dengan bahan tambah fly ash. Metode yang digunakan dalam penelitian ini adalah metode eksperimen. Penelitian dirancang dengan empat perlakuan, tiap perlakuan diulang tiga kali. Hasil penelitian menunjukkan bahwa material over slabbing untuk penguat perkerasan kaku menghasilkan nilai kuat tekan beton rata-rata tertinggi pada variasi kadar fly ash 10% sebesar 24,05 Mpa. Kuat lentur rata-rata tertinggi pada variasi kadar fly ash 10% sebesar 3,02 Mpa, ini tidak memenuhi syarat kekuatan rencana pada umur 28 hari sebesar 3,78 MPa. Modulus elastisitas beton rata-rata tertinggi pada variasi kadar fly ash 10% sebesar 23,066 103 Mpa. Nilai koefesien permeabilitas beton terbesar pada variasi kadar fly ash 30% sebesar 1,723 10-5 m/det dan nilai koefesien permeabilitas beton terkecil pada variasi kadar fly ash 10% sebesar 3,393 10-5 m/det, nilai koefesien permeabilitas beton seluruhnya memenuhi syarat ACI 301-729 sebesar 1,5 10-11 m/det. Susut terbesar terjadi pada baton dengan variasi kadar fly ash 30% sebesar 702,222 microstrain sedangkan susut terkecil terjadi pada beton dengan variasi kadar fly ash 10% sebesar 502,500 microstrain

Tasikmalaya City is one of the cities located in the southeastern part of West Java Province, included in 2 (two) watersheds, namely Citanduy and Ciwulan. The condition of the existing canal in the City of Tasikmalaya is still considered insufficient to accommodate the overflow of rainwater, so that many areas are still inundated. This study looks for the priority scale of thinking handling, knowing the performance of drainage in the selected location, and getting the concept of handling the drainage channel at the selected location. Channel channel priority scale using ANP software. Performance is reviewed based on discharge at 1, 2, and 5 years by using SWMM. The concept of improving the drainage system is carried out using two scenarios, namely increasing the dimensions of the channel and reducing the amount of air runoff by making infiltration wells. The results of the analysis show that the priority of channel repairs on Jl. HZ Mustofa. The channel capacity is based on the discharge of the 1 year return period there are 11 overflowing drainage channels, the 2 year return period there are 15 overflowing drainage channels and the 5 year return period there are 16 overflowing drainage channels from 43 drainage channels. The concept of canal management can be implemented, but there are land constraints. If the infiltration well is applied in accordance with the calculation results, the 1-year return discharge is reduced by 24.65%, the 2-year return period is reduced by 19.63%, and the 5-year return period is 18.18%. However, the use of infiltration wells is considered ineffective to reduce rainwater runoff, but has a positive impact on groundwater conservation.

Tasikmalaya is a city that has problems with drainage channels. The location of area from this city that is often to a flood point is AH Nasution Street, Mangkubumi. The largest height of the flood is 50 cm with longest duration of flooding after the flood is started . The purpose of this research is to find out condition of the drainage channel of AH Nasution Street, Mangkubumi, length of drainage is 800 m. The study research using EPA SWMM 5.1 and to find the effective drainage to deal with frequent floods. The results of this research can be concluded that the condition of the channel on AH. Nasution street needs to be repaired, the drainage of this channels is overflow. After the simulation running there are 12 drainage channels that experience overflow and the the largest discharge is at the point of the outfalls 2 (SP.2) with 0.850 m3 / sec. On the channel of drainage AH Nasution Street was calculate to redesigned 2 types of drainage. The typical dimensions with calculation results formula is b = 1 m and H = 1.07 m and the outfalls drainage channel is b = 1 m and H = 1.33 m.

TKota asikmalaya merupakan kota yang bermasalah dengan saluran air. Salah satu kawasan yang sering menjadi titik banjir adalah Jalan SL Tobing, Kecamatan Cihideung, Kota Tasikmalaya, lokasi penelitian dimulai dari saluran Kantor Badan Kepegawaian Daerah, saluran di depan SPBU Walikota SL Tobing dan saluran limbah jalan Cipinang. Titik pusat titik banjir terjadi di saluran Kantor Radar Tasikmalaya dan pertigaan Jalan SL Tobing hingga Jalan Cipicung, dengan ketinggian terbesar sekitar 60 cm dan durasi banjir terlama setelah kejadian yaitu 24 jam jika hujan. tidak berhenti. Tujuan dari penelitian ini adalah untuk mengetahui kondisi saluran drainase di Jalan SL Tobing Kecamatan Cihideung Kota Tasikmalaya sejauh 1050 m menggunakan EPA SWMM 5.1 dan mengetahui saluran drainase yang efektif untuk menghadapi banjir yang sering terjadi. Hasil penelitian ini dapat dikatakan bahwa kondisi saluran di jalan SL perlu ditingkatkan, karena masih ada beberapa saluran yang mengalami luapan. Hasil simulasi dengan menggunakan software EPA SWMM 5.1 menunjukkan debit terbesar sebesar 1,024 m3/detik dengan luas daerah tangkapan sebesar 32.037 Ha.

The number of people who increase every year has resulted in the shift of land use in every place, not least in the city of Tasikmalaya. This change in land use indirectly results in reduced water catchment areas so that when it rains with high intensity it will cause inundation. Inundation in urban areas can be caused by several factors, for example due to a disturbed drainage system. The purpose of this study was to determine the condition of the drainage channel on the Bantar street of Tasikmalaya City and to determine the ideal drainage channel to deal with frequent floods.The method used in this research is direct measurement in the field (observation) by taking existing channel data consisting of the coordinates of each channel for each stationing, field contour data, and channel dimensions. Then the data is processed to determine the condition of the drainage channel that will be used for the analysis of the ideal channel capacity to deal with flood problems at the research location.The results of this study can be concluded that the condition of the existing channels on the outskirts of the city of Tasikmalaya some already exist that are not suitable for use, and must be immediately replaced with a more ideal channel so that the water discharge can flow smoothly and the dimensions of the channel are ideal for maximum water flow. on the Bantar City Tasikmalaya road section, the width (b) = 0.8 height (H) = 0.9 and guard height (W) = 0.6 with a drainage coefficient (C) = 0.70, and land slope (s) =0.02.

ABSTRACT City transportation as part of public transportation plays an important role in supporting the mobility of residents of the City of Ciamis. City transportation has the most number of fleets compared to other types of public transportation. The population itself continues to increase over time. This condition causes an increase in population mobility so that the existence of city transportation can help people's activities and mobility in their daily lives. In this study, an analysis of the performance of urban transport operations in the city of Ciamis was carried out, the aim was to determine the success of procuring urban transportation for the benefit of operators and users. Performance measurement is carried out using indicators of passenger waiting time, vehicle speed, density, headway and passenger load factor. The standard time between or headway is 1-12 minutes and the waiting time for passengers is an average of 5-10 minutes and a maximum time of 10-20 minutes refers to the standard determined by the Directorate General of Land Transportation. Based on the results of research on the headway value used in city transportation from each route, the average time interval between the first vehicle and the next vehicle is currently quite effective because it is still within the tolerance limits of the Department of Transportation regulations, which is 1-12 minutes, while the average headway City transportation is 3 minutes. The performance of city transportation when viewed in terms of efficiency and effectiveness from the survey results, city transportation at the Ciamis Terminal is quite good
