Abstract

Mortar sebagai repair material relatif mudah dibuat dan diaplikasikan di lapangan. Pembuatan dan penggunaan mortar relatif lebih mudah dibandingkan dengan beton sendiri. Namun, mortar belum memenuhi sebagai repair material. Untuk itu, mortar perlu ditambahkan dengan material lainnya guna menambah kuat lekat antara repair material beton. Salah satu material yang dapat digunakan adalah polymer. Metode penelitian yang digunakan adalah metode eksperimen. Penelitian dirancang dengan 5 perlakuan untuk uji kuat lekat dan susut (shrinkage), perlakuan yang diujicobakan yaitu penambahan polymer 0%, 2,5%, 5%, 7,5% dan 10% dari berat semen dan variasi campuran serat bambu 1%, 2% dan 3%. Hasil penelitian menunjukan bahwa penambahan polymer pada mortar berserat bambu mempengaruhi nilai kuat lekat dan susut (shrinkage) mortar. Kuat lekat mortar berserat bambu tertinggi pada variasi penambahan polymer 5% yaitu sebesar 4,33 Mpa, 4,72 Mpa dan 4,07 Mpa pada mortar berserat bambu 1%, 2% dan 3%. Sedangkan kuat lekat mortar berserat bambu terendah pada variasi penambahan polymer 10% yaitu sebesar 2,10 Mpa, 2,36 Mpa dan 1,84 Mpa pada mortar berserat bambu 1%, 2% dan 3%. Mortar berserat bambu yang mengalami susut paling besar pada variasi penambahan polymer sebesar 10% yaitu sebesar 703,333 microstrain, 695,000 microstrain dan 708,333 microstrain pada mortar berserat bambu 1%, 2% dan 3%. Sedangkan mortar berserat bambu yang mengalami susut paling kecil pada variasi penambahan polymer 5% yaitu sebesar 573,333 microstrain, 563,333 microstrain dan 611,667 microstrain pada mortar berserat bambu 1%, 2% dan 3%. Variasi penambahan polymer yang optimum sebesar 4,48% menghasilkan kuat lekat maksimum sebesar 4,402 MPa dan susut yang minimum sebesar 563,333 microstrain .

Abstract

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

Abstract

One of the important things in activities to get the necessary cost calculations for development is to make a Budget Plan (RAB). Calculation analysis is needed to get a budget plan that is accurate and close to the actual budget in implementation, as well as a guide for owners in providing funds. In the analysis, it must be made in detail in order to obtain optimal calculation results, one of which is the analysis of the budget plan with three case study methods for making simple residential houses. The purpose of this study was to determine the calculation of the budget with the method of SNI, BOW and Regional Price I Ciamis Regency and the most economical method of the three methods. In this study, three analyzes were carried out, namely BOW (Burgerlije Openbare Werken) analysis, 2002 SNI and Price analysis for Region I Ciamis Regency, all of which used the reference price of materials, the price of labor wages and the same volume of work, namely in related manufacturing. From the research results obtained: Budget Plan based on BOW analysis of Rp. 16,076,465.00. The Budget Plan based on the 2002 SNI analysis is Rp. 14,305,678.00. Budget plan based on Local Area Price analysis of Rp. 12,406,295.00. Of the three analyzes the lowest price is to use the price analysis of Region I Ciamis Regency (Local Price Standards in 2020) Indonesia.

Abstract

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
