Abstract

This research was conducted by using non-destructive test method and destructive test to investigatethe compressive strength of repaired concrete masonry wall with chemical additive sited at Sriwulan Village which is tidal flooding prone area and PucangGading Village. Non-destructive test using Hammer Test was conducted at age 12 months, 13 months, and 14 months after concrete masonry wall being repaired.It was found that in Sriwulan Village, the highest compressive strength is 49.37 MPa at age 14 month whilethe highest compressive strength value is on the in PucangGading is 50,51 MPa at age 13 month. It was also found that destructive test using Core Drill Test was conducted at age 14 month after the masonry wall have been repaired. The highest compressive strength in Sriwulan village was 58,6 MPa and in PucangGading was 82,63 MPa.

Abstract

Rawa Pening soil contains peat has low level of California Bearing Ratio (CBR) and high permeability so it is less suitable for embankment. Above the embankment functioned as a road body. This study adds cement and matos (normal) to increase soil bearing capacity. (50%), 50% G 50% Cement (C) 8%, TSRP 50% + G 50% + C 8% + Matos (M) 2%, 4% and 6%. CBR soaked, normal results obtained CBR 2.99% while the CBR requirement of 5.44%. Addition of C 8% adds CBR value to 9,25%, while addition of M 2% increase CBR value equal to 8,9%, M 4% yield CBR become 16% and M 6% get CBR equal to 16%. Low compaction, normal soil undergoes seepage after a day, compaction is undergone seepage after 3 days and standard compaction does not undergo seepage for 7 days. The most optimal result, with stabilization of C 8% and M 4%. Addition of M 2% is not effective or equal to 8% cement. The addition of M 6% equals M 4%.

Abstract

Tanah merupakan bagian yang sangat penting dan harus diperhatikan kondisi dan karakteristiknya sebelum melakukan proses perencanaan maupun pelaksanaan pekerjaan konstruksi. Tanah sebagai dasar dari pondasi diharapkan memiliki daya dukung yang tinggi dan mengalami penurunan yang relatif kecil. Dalam perencanaan kontruksi berskala besar, pengujian tanah dilakukan untuk mendapatkan nilai parameter tanah sehingga jenis dan sifat tanah dapat diketahui dan meminimalkan risiko keruntuhan dan terjadi kegagalan struktur tanah pondasi yang juga bisa berakibat kegagalan struktur di atasnya. Subgrade merupakan lapisan tanah yang paling bawah dan paling dominan menahan beban konstruksi. Pemadatan tanah dasar sangat diperlukan jika tanah dasar tersebut memiliki kualitas yang kurang memenuhi spesifikasi atau kurang mendukung untuk menerima beban konstruksi.Salah satu faktor parameter tanah yang mempengaruhi daya dukung kekuatan tanah adalah modulus reaksi subgrade (ks). Pada perencanaan perkerasan, nilai modulus reaksi subgrade(ks) diambil dari NAASRA (National Association of Australian State Road Authorities) yang membuat grafik hubungan nilai ks dan nilai California Bearing Ratio berdasarkan hasil pengujian di lapangan. Melalui penelitian ini akan dicoba menemukan hubungan antara nilai ks dan CBR berdasarkan pengujian di laboratorium dan akan dibandingkan dengan hasil grafik NAASRA.

Abstract

Precast material is a user-friendly construction product. One innovation that is being developed is sandwich concrete. Sandwich concrete is composed by skin layers, that are strong and stiff, and lightweight concrete as core layer. As a part of builiding construction, each structural and non-structural element resists load in certain time. The purpose of this research is to investigate creep performance of concrete sandwich beam. By observing the effect of creep, it can be known the long-term effect due to the constant loading on a material. The test specimen is formed of sandwich construction beam, with its core layer consists of lightweight concrete and styrofoam (cement EPS sandwich panel) mixture. This research conducted with two kinds of size and proportions of specimen, single beam (length=100 cm; width=20 cm; thickness=7,5 cm)and double beam (length=100 cm; width=20 cm; thickness=7,5 cm)which is a combination of single beams glued together with Sikabond. The loading method that used in this research is third point loading as described on ASTM C393 in two positions, horizontally and vertically. After having loaded of 3 kN in 2 hours, each test specimen has deflected and gives creep strain value. The values of creep strain are: specimen RH-S01 by 3,23%, specimen RV-S03 by 0,40%, specimen RH-D03 by 0,60%, dan specimen RV-D02 by 0,32%.The smallest value of creep strain obtained by double beam that was tested vertically, due to have greater EI value than the horizontally tested specimens. According to the maximum deflection and load that can be resisted by the specimens, sandwich concrete shall not be recommended for structural beam. This research shows that the creep effect of constant loading by 3 kN for 2 hours on sandwich concrete beam is not secure

Abstract

Kecelakaan lalu lintas merupakan permasalahan lalu lintas baik di tingkat global, di Indonesia maupunKota Semarang. Hampir setiap hari berita kecelakaan lalu lintas jalan raya selalu menghiasi mediacetak maupun elektronik di Kota Semarang. Semakin meningkat jumlah penduduk di Kota Semarangmemberi potensi peningkatan kejadian kecelakaan lalu lintas, hal ini disebabkan semakin banyakpergerakan lalu lintas di ruas-ruas jalan Kota Semarang. Tujuan penelitian ini adalah untukmengetahui tingkat keselamatan lalu lintas jalan raya di Kota Semarang yang direpresentasikan dalamangka kecelakaan berbasis jumlah penduduk dan panjang jalan serta indeks severitas. Metodeperhitungan menggunakan metode yang dikembangkan oleh Pignataro (1973) dengan mengambil datajumlah kecelakaan dan korban yang tercatat di Kota Semarang. Hasil perhitungan menunjukkan bahwaangka kecelakaan berbasis jumlah penduduk menunjukkan penurunan yaitu dari 67,31 pada tahun2012 menjadi 50,32 pada tahun 2015, ditinjau dari panjang jalan terjadi penurunan dari 0,39 padatahun 2012 menjadi 0,30 pada tahun 2015, namun indeks severitas terjadi peningkatan yaitu 0,13 padatahun 2011 menjadi 0,24 pada tahun 2015. Hal ini menunjukkan bahwa tingkat keselamatan lalu lintasdi Kota Semarang terjadi penurunan, untuk itu perlu upaya penanganan serius oleh Pemerintah KotaSemarang dengan melibatkan seluruh stakeholder yang ada

Abstract

Paving block merupakan salah satu bahan bangunan yang digunakan sebagai alternative perkerasan jalan. Bahan penyusun dari paving block adalah semen, pasir dan air dengan atau tanpa bahan tambah lainnya. Bahan tambah yang digunakan dapat berupa limbah atau sisa bahan bangunan yang tidak digunakan. Penggunaan limbah bertujuan untuk meningkatkan mutu paving block dan memanfaatkan limbah secara optimal. Limbah keramik lantai merupakan contoh limbah yang banyak ditemukan di sekitar lingkungan. Oleh sebab itu, perlu diadakan penelitian untuk mengetahui pengaruh nilai kuat tekan paving block akibat penambahan pecahan keramik. Dalam penelitian ini digunakan perbandingan semen dan pasir adalah 1:5 dengan presentase pecahan keramik 0%, 5%, 10% dan 15% dari berat pasir. Nilai f.a.s yang digunakan adalah 0,3. Hasil pengujian nilai kuat tekan pada prensentase 0% adalah 424,167 kg/cm2, nilai kuat tekan pada prensentase 5% adalah 436,667 kg/cm2, nilai kuat tekan pada prensentase 10% adalah 465 kg/cm2 dan nilai kuat tekan pada prensentase 15% adalah 523,333 kg/cm2. Nilai kuat tekan tertinggi pada pecahan keramik sebanyak 15% yaitu 523,333 kg/cm2. Peningkatan kuat tekan terjadi sebesar 23,38% dari presentase pecahan keramik 0% terhadap pecahan keramik 15%. Nilai kuat tekan tersebut memenuhi persyaratan standar mutu kelas I/A dengan kuat tekan rata-rata 400 kg/cm2 dan minimal 350 kg/cm2. Dari hasil penelitian, dapat disimpulkan bahwa pecahan keramik dapat meningkatkan mutu paving block seiring dengan penambahan presentase pecahan keramik.
