Abstract

Kegiatan proyek sebagai lahan usaha industri konstruksi memiliki karakteristik khusus yang membedakannya dengan  kegiatan operasional.  Kondisi  ideal  bagi pelaksana konstruksi yaitu  ketika  seluruh  komponen kontrak konstruksi dengan pengguna jasa diuraikan secara jelas dalam surat perjanjian, syarat umum kontrak, syarat khusus kontrak, spesifikasi ekternal, gambar rencana, dan daftar kuantitas. Sebagaimana bagian dari proses Manajemen Proyek, perencanaan dan pengendalian yang baik belum menjamin terwujudnya efektivitas sasaran proyek. Terjadinya perubahan pekerjaan pada proyek konstruksi dapat memberikan dampak negatif secara langsung dan tidak langsung, bagi kontraktor maupun bagi pemilik. Dampak perubahan pekerjaan secara langsung adalah penambahan biaya item pekerjaan karena adanya volume dan material, konflik jadwal pelaksanaan, pekerjaan ulang, meningkatnya overhead dan meningkatnya biaya tenaga kerja. Analisis korelasi dan analisis regresi menunjukkan bahwa faktor teknis, faktor administrasi dan faktor personil yang menyebabkan terjadinya addendum mempunyai  pengaruh  terhadap efektivitas pencapaian sasaran proyek Kata-kata Kunci: addendum, efektivitas sasaran proyek

Abstract

One of the factors causing the cracking of rigid pavement surfaces for roadways is the occurrence of tensile stresses due to vehicle wheel loads that exceed the tensile stresses of the concrete, if not handled immediately will affect the service life of pavement construction.This research is conducted to get alternative solution from pavement construction problem, that is damage before end of service period. One of the efforts that can be done is to make a model of pavement construction that can reduce the tensile stress on the underside of the concrete plate by adding a stiffening block on the underside of the concrete plate for road pavement. The results of this study are expected to be one form of innovation from rigid pavement construction that can be applied in Indonesia.  On the basis of this then the researchers took the title "Performance Pavement Pavement Construction Model with the Confession Block".The purpose of this research is to know the effect of the addition of the stiffening block on the pavement construction model with the stiffening block, compared to the pavement model without the stiffening block, in terms of the number of load repetitions and the cracking patterns occurring on the surface of the concrete plate.Pursuant to result of research with experimental method on pavement model with size of width 50 cm, length 50 cm and thickness 3 cm. Data obtained that the performance of pavement model with the stiffening block, able to reduce crack width by 41.82%. Maximum load repetition on pavement model with Type I block 31.33% higher than the maximum load repetition on pavement model without stiff block (Type II). The damage patterns that occur in Type I pavement models, beginning with cracks in the corners, followed by cracking in the middle until the plate is split.

Abstract

Proyek konstruksi erat sekali dengan jadwal kerja yang padat bagi pekerjanya sebagai sumber daya utama dalam sebuah pencapaian proyek. Situasi proyek yang dinamis dengan mobilitas tinggi dapat memicu ancaman kecelakaan yang dapat terjadi setiap saat bagi pekerja selama jam kerja. Selain kondisi internal pekerja, kecelakaan dapat disebabkan oleh karakteristik lingkungan proyek. Monitoring keselamatan pekerja konstruksi diperlukan untuk menghindarkan pekerja konstruksi dari potensi kecelakaan akibat adanya bahaya dari karakteristik proyek konstruksi seperti lubang pada lantai (hole/opening) dan sisi tepianyang terbuka (unprotected side). Karakteristik proyek yang membahayakan pekerja konstruksi dapat dikendalikan dengan upaya penggunaan peralatan keselamatan kerja sehingga kemungkinan kejadian kecelakaan dapat diminimalkan. Untuk itu penelitian ini bertujuan membangun sebuah model sistem monitoring keselamatan pekerja konstruksi guna mencegah kecelakaan konstruksi. Pendekatan fuzzy logic adalah pilihan yang tepat untuk digunakan dalam analisa karena penilaian masalah keselamatan kerja merupakan salah satu pembahasan yang bersifat kualitatif sehingga lebih sulit diukur secara tepat dalam sebuah angka yang pasti. Identifikasi karakteristik proyek yang menyebabkan kecelakaan menghasilkan variabel input berupa tinggi jatuh, jarak hazard dan sistem proteksi yang digunakan pada proyek. Nilai pada variabel input diubah ke dalam bahasa linguistik untuk proses fuzzifikasi. Pendekatan knowledge based digunakan untuk proses inferensi yang dituangkan dalam aturan-aturan fuzzy untuk kemudian digunakan sebagai pengambilan keputusan dengan output tunggal yakni tingkat bahaya kecelakaan yang dialami pekerja konstruksi ketika bekerja. Hasil pendekatan dapat menunjukkan tingkat bahaya yang dapat terjadi sesuai dengan kondisi karakteristik proyek tempat pekerja beraktivitas sehingga dapat digunakan sebagai dasar pengambilan keputusan pencegahan kecelakaan konstruksi. Kata-kata Kunci: fuzzy logic, monitoring keselamatan, pekerja konstruksi

Abstract

Genting is a utility roof materials above the building that serves as a protective weather and channeling rain water that was on it down. Alternative yangb concrete tiles is done more efficiently without the combustion process. Kelud the ash sand fly bergradai to the distance, in other words the farther the distance of the small grain diameter at a given radius. The heat caused by the Volcanic magma, ash makes Kelud Sand has a high water absorption, but will have saturated and rejected, resulting in bledding. By mixing sand times as a species, then an increase hidroulis and mechanical properties of an ideal mix ratio. From the experiment results for the compressive strength of the mixture 2: 2: 1 is stronger ie max 108.00 kg /cm2, a mixture of 3: 2: 1 compression stress value obtained sbesar 64.00 kg /cm2 and the mixture of 4: 2: 1 obtained compressive stress value of 24.00 kg /cm2. As for the bending stress fracture to a mixture of 2: 2: 1 max values obtained at 33.5 kg / cm2and for a mixture of 3: 2: 1 max values obtained at 23.33 kg /cm2 while for mixture 3: 2: 1 obtained value max of 5.33 kg /cm2, and water absorption in the saturated surface dry condition for a mixture of 2: 2: 1 obtained 10.23%, water absorption in the saturated surface dry condition for a mixture of 3: 2: 1 obtained 11.82 %, water absorption on the condition of saturated surface dry to mix 4: 2: 1 obtained 12.81%,. Then for mains water tembur can be seen in the discussion section, but can be inferred to mix 2: 2: 1 is more dense because Crystal showed a copy with a little water and a relatively dry and to a mixture of 4: 2: 1 indicates a copy with softer water crystals and evenly with a small diameter, both assessed at the time of maximum concentration, while for the mixture 3: 2: 1 is more porous at the same time.
