Suatu proyek dikatakan sukses apabila minimal memenuhi empat faktor, antara lain adalah proyek berjalan sesuai jadwal kontrak, mendapatkan keuntungan karena pengeluaran sesuai dengan yang direncanakan, masalah yang terjadi dalam proyek kecil, dan tidak terjadi kecelakaan kerja. Jika teknis yang digunakan kurang baik maka akan berdampak buruk pada kinerja proyek dan dapat menimbulkan kerugian dari segi biaya, mutu, dan waktu. Salah satu kerugian yang ditimbulkan pada pelaksanaan proyek konstruksi disebabkan oleh karena adanya pengerjaan ulang (rework). Tujuan penelitian ini adalah untuk mengetahui faktor-faktor yang menjadi penyebab rework dan faktor dominan apa saja yang menjadi penyebab rework pada pelaksanaan proyek gedung di Kota Padang tahun 2019. Penelitian ini menggunakan instrumen kuesioner yang melibatkan 22 orang responden, terdiri dari 11 perusaaan kontraktor dan masing-masing perusahaan terdapat 2 orang responden yaitu project manager dan site manager. Uji yang dilakukan meliputi uji validitas, reabilitas, korelasi Pearson Product Moment dan analisis deskriptif berdasarkan nilai mean dengan bantuan program Statistical Package for Social Science (SPSS) for Windows version 24.0. Penelitian ini mengidentifikasi 5 faktor penyebab terjadinya rework: faktor manajerial, faktor metoda pelaksanaan konstruksi, faktor material, faktor sumberdaya manusia dan faktor site conditions. Hasil penelitian menunjukkan bahwa faktor paling dominan penyebab rework adalah faktor manajerial, pada sub faktor kurangnya kerja sama tim (teamwork) sehingga hasil konstruksi tidak sesuai dengan kontrak (X1.4) dengan nilai mean 4.32 dan persentase sebesar 86.64 %.

The road in west sumatera generally using flexible pavement, asphalt concrete binder course is used to hold the travic load, that’s why it is necessary to have a mixture with enough strength (Ariawan, 2007). Palm is one of nature resource which is widely available in west sumatera that produce palm oil. Pecentage refusal density is a state where asphalt mix that being compacted is much more bigger as simulation for secondary density, so when the mixture can’t be compacted anymore because of VIM refusal is decreasing result from the compacting until the ultimate state. The purpose of this research is to get the optimum bitumen content refusal with percentage refusal density method start from VIM refusal limit state ≤ 2% from the mixture with palm oil percentage 0%; 2,5%; 5%; 7,5%; 10%; 12,5%; and 15%, as the coarse aggregate substitute. The result from research show that the value of optimum bitumen content refusal from each mixture is 5,5%; 5,55%; 6,05%; 6,1%; 6,35%; 6,35%; and 6,45%. From research result, the sample of asphalt concrete binder course mixture with palm oil as substitute is satisfy the standard and can be used.

AC-BC coating is one type of hot mix asphalt with a minimum thickness of 4 cm. The most important characteristic of this mixture is the stability of the surface layer where the surface layer must be able to accept all types of work loads. As a foundation layer, the asphalt content it contains must be sufficient so that it can provide a waterproof coating. The aggregate used is rather rough compared to the surface wear layer. The aggregate requirement that dominates in the asphalt mixture makes us research what materials can be used as a mixture in the asphalt mixture. Palm oil waste provides an alternative opportunity as a material making up the asphalt mixture. The intended waste is oil palm shell which can be used as a substitute for coarse aggregate in asphalt mixture. The purpose of this study is to obtain the ACO BC mix KAO calculation without using an oil palm shell and using a palm oil shell with variations of 2.5%, 5%, 7.5%, 10%, 12.5%, and 15% as substitution of coarse aggregate and know the effect of adding palm shells to the mixture of test specimens on Marshall parameter values. Before the manufacture of test specimens, the materials are tested in advance in accordance with the 2010 Revised 3 General Specifications. 3. The addition of oil palm shells to the asphalt mixture showed an increase in KAO value. Based on the results of the study, the oil palm shell was suitable as an additive to the Asphalt Concrete-Binder Course (AC-BC) mixture because it met the requirements of the 2010 Revised 3 General Bina Marga General Specifications.Keywords: mixture of AC-BC, oil palm shells, KAO, Marshall parameters

Toe Scour around abutment will be very dangerous and cause loss of stability on the bridge. The case of structure failure on Batang Kalu bridge in Korong Pasa Usang Nagari Kayu Tanam, Padang Pariaman Regency on Monday (10 December 2018) is a clear example of toe scouring. A case study of toe scour was on the Batang Kalu River bridge structure has been carried out. Rainfall data closest to the study location, Kandang Empat Station was used to minimize the errors in the calculation of flood discharge design. Numerical modeling with HEC RAS and scouring estimation with some empiric equation was conducted to predicting scour depth on abutment. Simulation results show scour depth results to an average of 2.731 m and close to the scour depth that occurred in the field (2.83 m). Results showed that the local scouring in the Batang Kalu River bridge structure can be suspected as the influence of the increasing river steepness. Discharge that is triggered by heavy rain with a long duration and increased river flow velocity due to steepness has the potential to create a very intense scouring. Increasing of steepness may have been caused by sand mining activities in the upper reaches. Further studies are needed to see the potential slope changes due to exploitation in the Batang Kalu River upper reaches

South Solok Regency with a population of more than 163,000 people, 62.3% without access to clean water services through the Domestic Water Company (PDAM). The number of PDAM customers has been changed in Solok Selatan Regency in the last five years. Since the water capacity is very limited which means it difficult to increase the number of customers, so it is predicted to be unable to meet the increasing need for clean water. Based on the study of the potential for raw water availability in the South Solok Regency, Sungai Kapur has the potential as a source of raw water. To complete the potential study, it is necessary to know the quantity of raw water by examining hydrological parameters to optimize the planning of water resources potential. The quantity of raw water is assessed by the dependable flow to determine the low flow characteristic. Based on calculations, obtained a reliable discharge of 90% in monthly that can be used as raw water. The raw water source used has a discharge of ± 138.6 l / sec. However, the availability is uneven throughout the month, so a reservoir is needed to guarantee the availability of raw water for residents. In addition, raw water quality is assessed in terms of physical, chemical, and biological aspects. The results of the raw water quality test in the Sungai Kapur are eligible for raw water based on Government Regulations No. 82, 2001
