Infrastructure Development Certification of Human Resources Deputy Building 3 is planned as one of the supporting facilities to improve the quality of human resources, especially in the environment Badan Siber dan Sandi Negara, Indonesia. The purpose of this study is to find out the results of the analysis of the types of risk of K3 in the erection work in Project Pembangunan Infrastruktur Sertifikasi SDM Badan Siber dan Sandi Negara and know the types of K3 risks that play the most role that occur in erection work in  Project Pembangunan Infrastruktur Sertifikasi SDM Badan Siber dan Sandi Negara. Using the research method of the survey method that will be validated by K3 Experts. The survey results from the respondent questionnaire were processed using the SPSS (Statistical Package for Social Science). To analyze risk, use the result of multiplying the average opportunity value and the average impact value.

Rampa street - Poriaha / Mungkur (WINRIP) is one location that has a slope angle on its slopes prone to landslides, causing damage to some roads. Based on these conditions, the Ministry PUPR slope handling project launched on this road. In practical improvements slope stability was conducted using three methods: manlift, hanging platforms and scaffolding. All three methods have their advantages and disadvantages in terms of both cost and time. To obtain the results of the comparison of cost and time to do the direct observation and study of literature, the comparative results obtained on the cost and time to get the method implementation in accordance with needs. From the three methods, the lowest cost and the fastest duration of the results implementation method using manlift with cost of Rp 1,557,623,470 and duration of work 29 days

Low geographical conditions and flowed by many rivers and the reduction of retention ponds in Jakarta, then built a reservoir. However, during the implementation period, it was delayed by 9.74%. One of the things that can be done to overcome delays is to choose a method of implementation. The method is diversion and dewatering. The results of the analysis are expected to produce a large comparison of the costs and time of each method. From the analysis results, the cost of implementing the method of soil and rock diversion in the box culvert work is Rp. 363,935,953, while the sandbag diversion method is Rp. 332,805,831. For box culvert work using open pumping dewatering method, the required cost is Rp. 394,637,510. From these data, it was concluded that the difference in the cost of diversion sandbag and rock soil was Rp. 31,130,122. While rock soil and dewatering diversion are Rp. 30,701,557. As well as sandbag diversions with dewatering of Rp. 61,831,679.  The results of observations of the implementation time obtained the conclusion that the work of box culvert with sandbag diversion method takes 35 days, and rock soil diversion  49 days while dewatering 63 days. By time comparison the sandbag diversion method is 14 days faster than rock soil diversion, and 28 days compared to the dewatering method. From these data, it can be concluded that in terms of cost and time, the sandbag diversion method is more economical and efficient than the other two methods.

The Indonesian government stepped up infrastructure projects in the country for logistical and economic equality equalization, infrastructure in the form of a Freeway. This study aimed to analyze and compare the costs, timing, and precise method in Fullslab Precast erection work on 1 module. The data used are primary and secondary. Using the method of removal/erection with heavy equipment cranes. For the calculation of comparative analysis is obtained by analysis of the cost and time analysis. Field observations, and direct cost analysis calculation, and not directly into the calculations that will be loaded to get the proper method to the cost and time of work. The results of the right method are method 1 Crawler Crane at Rp 206.598.086,00.

Pada saat ini perkembangan teknologi konstruksi yang bervariasi menjadikan alternatif yang cukup baik dalam pembangunan proyek konstruksi, akan tetapi keterbatasan sumber daya yang ada menjadi tolak ukur yang dipertimbangkan dalam pemilihan metode maupun material yang akan digunakan dalam pelaksanaan konstruksi. Seluruh stake holder terkait dalam pembangunan sangat mengharapkan pekerjaan dapat dilakukan dalam waktu yang singkat, mutu yang dapat diandalkan dan biaya yang ekonomis. Bila dilihat dari sudut pandang kontraktor, biaya yang dikeluarkan menjadi salah satu faktor yang sangat berpengaruh dalam pelaksanaan konstruksi, oleh karena itu pemilihan metode perlu direncanakan dan diteliti secara matang. Cara yang digunakan dalam pelaksanaan konstruksi yaitu dengan mencari alternatif bekisting di dalam pelaksanaan konstruksi. Hasil dari analisa biaya pada masing-masing metode bekisting dalam /m2 yaitu : biaya bekisting konvensional sebesar Rp. 401.228, biaya bekisting bondek sebesar Rp. 236.835, biaya bekisting deckslab precast sebesar Rp. 1.069.303. Dari hasil analisa tesebut maka dapat disimpulkan, metode bondek adalah pilihan yang tepat untuk digunakan sebagai bekisting pelat lantai pada jembatan karena biaya yang dikeluarkan lebih efisien bila dibandingkan dengan bekisting konvensional dan deckslab precast.
