Abstract

Perbaikan pada tanah lempung umumnya menggunakan metode stabilisasi untuk memperbaiki sifat-sifat tanah lempung dengan bahan tambahan yang di campurkan pada tanah lempung asli sehingga meningkatkan kuat dukung tanah sesuai spesifikasi teknis dalam kontruksi bangunan. Egg Shell Powder (ESP) merupakan hasil limbah dari rumah tangga maupun insdustri rumahan yang mempunyai kandungan kalsium karbonal (CaCO3) cukup tinggi sehingga dapat mengisis lubang antara pori-pori dan merekatkan partikel-partikel tanah. Sedangkan Sugarcane Pulp Ash (SPA) merupakan salah satu limbah dari hasil rumah tangga maupun pengolahan tebu yang tidak dimanfaatkan oleh masyarakat sekitar sehingga dapat mengurangi polusi lingkungan. Metode penelitian yang dilakukan dalam penelitian ini adalah pengujian laboratorium terhadap nilai kadar air, berat jenis dan nilai CBR penambahan ESP dan SPA terhadap tanah lempung dengan variasi 0%, 5%, 10% dan 15% serta terhadap penambahan 5% SPA. Hasil Tanah asli dalam penelitian ini termasuk dalam klasifikasi tanah CL, yakni Lempung Tak organik dengan plastisitas rendah sampai sedang. Nilai kadar air optimum cendrung mengalami penurunan seiring dengan penambahan ESP dan SPA pada tanah asli yaitu pada variasi ESP 15% dan SPA Yaitu 19 % dan nilai berat jenis mengalami peningkatan yaitu 1,71 gg/cc . Peningkatan nilai CBR terjadi pada penambahan ESP 15% dan SPA 5% yaitu sebesar 9,23%.

Abstract

Earthquake and series of specific phenomena in Palu and any other parts of the world contributed to a liquefaction that was involving massive fatalities and economic loss. The evaluation of liquefaction potential based on standard penetration test (SPT) data using deterministic approach has been widely applied. A liquefaction index model is required for the determination of a limit state between liquefaction and non-liquefaction cases by the consideration of bias issues in deterministic method. This research is aimed at the determination of liquefaction index model in relating (N1)60 and CSR7.5 using multi-gene genetic programming (MGGP) to develop limit state curve and its comparison with previous studies. The developed liquefaction index model based on SPT data using MGGP resulted in a performance in terms of successful prediction of 93% for testing of datasets.

Abstract

Water construction developments are increasing over time with the aim of preventing floods, raising water levels, and helping water resource management. However, in the planning process, debit data for 20 years is very difficult to obtain. Therefore, there is a Synthetic Unit Hydrograph (SUH) method to help analyze without using rainfall data and only using watershed characteristics for hydrological analysis. In this study, we will analyze the synthetic unit hydrograph parameters using the Nash and Soil Conservation Service (SCS) methods and compare them with data from the Gemawang AWLR in the Code River sub-watershed. A comparison was made to find out which method is suitable for the Code River sub-watershed at the AWLR Gemawang station. The suitability index or R² of the two methods shows results that are close to one or very related. The regression angle of the variation SCS method obtained an angle of 38˚, at the time of rising 36.5˚ and at recession time of 38.6˚. The Nash variation method gets 40.1˚ for one hydrograph data, 40.6˚ for rising time and 43.3˚ for descending time.

Abstract

Proyek didefinisikan sebagai runtutan tugas yang harus diselesaikan untuk mencapai suatu hasil tertentu. Menurut Project Management Institute (PMI), istilah Proyek mengacu pada "setiap usaha dengan awal dan akhir yang pasti", meliputi berbagai macam industri, termasuk proyek konstruksi. Manajer proyek pada suatu proyek memiliki pengaruh terhadap kinerja pada pelaksanaan suatu proyek. Dengan demikian jenis kepimimpinan pada seorang manajer proyek juga akan berdampak terhadap kesuksesan proyek konstruksi. Lalu kepuasan kerja pada tim proyek merupakan perasaan/pendapat tim proyek akan pekerjaan mereka. Pada penelitian ini dilakukan analisa untuk mengukur pengaruh gaya kepemimpinan servant pada manajer proyek serta kepuasan kerja tim proyek, terhadap keberhasilan proyek dalam hal kinerja jadwal, kinerja biaya, kinerja kualitas, dan kepuasan pemangku kepentingan, terutama pada proyek-proyek konstuksi di Indonesia. Penlitian dilakukan dengan melakukan survey kuantitatif terhadap profesional proyek umum maupun proyek konstruksi di Indonesia dan kemudian hasil survey akan diolah dengan metode Structural Equation Modelling.

Abstract

Roads include land transportation facilities that are widely used for Indonesians in traveling near or far. The growth of globalization can also have an influence on the level of mobility which has an impact on vehicle users and continues to increase. This causes the volume load of vehicles to exceed the limits of the designed road class, so that the quality and age of the pavement will continue to decrease. This research was conducted to analyze the condition of road pavement damage to damage to the Jl. Raya Papar – Jl. Raya Minggir with a length of 3 km. The method used for this research is PCI (Pavement Condition Index) with the aim of finding values ​​based on the type, level and extent of damage to the method used and the selection of alternative treatments as a reference and road maintenance effort.
