Abstract During road reconstruction period, a negative impact was imposed on road users and the surrounding environment. These impacts are the result of the work zone which is used as working space and road reconstruction. This work zone is potential to influence the drivers stress and to decrease road traffic performance such as travel delays, congestions and road accidents. Guidelines for green (environmentally friendly) infrastructure defined in New Road Construction Concept (NR2C) in European infrastructure vision 2040 concept, can be used to mitigate this negative impact. Twenty projects of Balai V National Roads Improvement in East Java, and Balai VIII in Bali for fiscal year 2013 is used as a case study. Descriptive method used for the discussion of case studies. Management traffic safety in work zones assessed the suitability of the setting up of signs, markings and guardrail. Shift arrangements work during the day (peak hours) or night (off peak hour), is used as an indicator of the negative impact of road users and the environment. The analysis showed that the work zone management in the implementation of national road reconstruction projects toward green (environmentally friendly) construction concept. It is shown from the implementation of safety attributes average 68%, and the implementation of the reconstruction in the off peak hours by 55% of the projects. Keywords: road reconstruction, work zone, negative impact, green construction  Abstrak Pada saat pelaksanaan rekonstruksi jalan, dampak negatif akan  terjadi pada pengguna jalan dan lingkungan sekitarnya.

Abstract

The low standard of National road is continuously reconstructed to establish Trans National connectivities. During the reconstruction period, the loss of road user costs and the negative impacts for surrounding environment were inccurred. Predicted losses of road users have not been conducted, so that it is important to be investigated. Initially, road performances were analyzed during road reconstruction. The road performances were analyzed using a descriptive method. Road performance variable includes running costs referred to the Bina Marga guidelines of Pd - T-15 -2005- B. National road reconstruction project in fiscal year 2013 is used as a case study. The results of the analysis are obtained as follows: 1) speed (Vm) can be predicted from the exponential relationship model in which degree of saturation in pre-reconstruction (DSp) is used as a generator variable. This generator variable is predicted declining at 6 km/h (DSp = 0.1);  2) The traffic flow (Qm) is predicted by multiplying the current pre-reconstruction flows with a factor of Fq. Traffic flows is predicted declining by 28% (Fq = 0.72); and 3) The degree of saturation (DSm) is predicted by a factor of Fds and estimated to increase by 30% (Fds = 1.3).

Abstract

Road safety is a topic that came out over the years and has now become a worldwideproblem. This can be picked up with the founding of the Decade of Action for Road Safety 2010-2020 by the United Nations. Efforts of prevention road safety during the implementation of roadimprovement has been specified in the path of contract execution. However, assessment of safetyaudits in the work zone on the road improvements has not been studied. Descriptive method used toidentify related attributes of safety in the work zone. Hierarchy and the weighting of each attribute isused the Analytical Hierarchy Process (AHP) method. The results obtained in, the weighting of the 4criteria division of work zones in sequence from the weight of greater are: the work zone; closerszone; initial taper zone and end taper zone by weight are: 59%; 27%; 9% and 6%. Weight rating ofalternative attributes for closers zone criteria is: road work warning signs: lane usage instructionssigns; closers zone distance; narrowing of lanes of the road warning signs and speed limit warningsigns, with their respective weights are: 46%; 23%; 15%; 11%; 5%. Weight rating attributesalternative to early taper zone criteria are: the installation of cone/guardrail; reflector at the initial ofthe work zone; minimum taper length requirement with respective weights: 53%; 30%; 17%.Assessment criteria attribute for the work zone are: minimum length of the work zone; the minimalwidth of the work zone; installation cone/guardrail; and the minimum distance between work zones,with respective weights: 70%; 15%; 9%; 6%.

Abstract

ABSTRAK Perkembangan ilmu pengetahuan dan teknologi yang semakin cepat, dimana pertumbuhan dan perkembangan disebabkan oleh kebutuhan akan sarana dan prasarana yang memadai. Hal ini juga terjadi di Indonesia dimana perkembangan terjadi di bidang konstruksi baik dari segi disain maupun metode konstruksinya. Pemilihan strategi pembangunan sangat penting, karena pemilihan metode yang tepat sangat berpengaruh dengan hasil yang akan dicapai, dimana pemilihan metode tepat dan baik dapat diukur dari kinerja biaya, mutu, dan waktu. Pada pembangunan Mandarin Oriental Resort, PT. Bali Ragawisata selaku owner pada tahap konstruksinya menggunakan metode design and build. Sebelum dilakukan tahap konstruksi untuk mengurangi kerugiaan karena keterlanjuran penanaman modal, maka perlu dilakuknan analisis studi kelayakan. Analisis studi kelayakan pada resort ini akan menganalisis aspek pasar, aspek legalitas, aspek teknis, dan aspek finansial. Pada analisis aspek pasar untuk resort ini dikatakan layak karena masih memiliki peluang sebesar 3.482 kamar untuk tahun 2018. Analisis pada aspek legalitas yaitu kepemilikan dokumen-dokumen pelegalan perusahaan karena berhubungan dengan perizinan dan sebagai bukti kepatuhan terhadap hukum. Analisis pada aspek teknis menunjukan layak dimana KDB sebesar 47% dari persyaratan minimum 60%, KLB dengan nilai 21.465 m2 lebih rendah dari syarat yang ditetapkan sebesar 33.408 m2, nilai KDH 19% sudah melebihi batas maksimum 30%, dan Kebutuhan lahan parkir sebesar 33% dimana sudah melebihi syarat minimum 30%. Untuk analisis aspek finansial menunjukan hasil layak dimana nilai Net Present Value sebesar Rp. 292.137.054.746,00, Benefit Cost Ratio sebesar 1,223, Interal Rate of Return 18,236% dimana lebih besar dari nilai nilai MARR 13%, Discounted Payback Period Rp. 18.906.074.093,00, BEP pada tahun ke 9 bulan 8, nilai sisa dari bangunan dan tanah sebesar Rp. 22.660.800.000,00 dan pada analisis sensitivitas pada kondisi penurunan pendapatan sebesar 10 % dan kenaikan operasional 10% proyek dikatakan tidak layak.

Abstract

RISK MANAGEMENT DURING IMPLEMENTATION OF HOTEL CONSTRUCTION PROJECT AT SARBAGITA AREA ABSTRACT Construction project is an unique project and constrained by cost, quality and time. During construction project implementation, problems are frequently occur that affect toward cost, quality and time. Therefore according to such matter, it is considerably necessary to conduct research concerning risk management. Risk management include risk identification, risk analysis, risk acceptance distribution, risk mitigation and risk ownership. This research was conducted through interview with expert parties in hotel construction project implementation at Sarbagita (Denpasar, Badung, Gianyar, and Tabanan) region. This research aimed to identify and determine risk acceptance level, determine dominant risk, conduct mitigation action and risk ownership allocation. Total risks identified in this research were 37 risks that consist of 19 risks according to literature and 18 new finding risks. Dominant risk in this research were 28 risks, classified into 19 undesirable risks and 9 unacceptable risks. Both risks frequently occur in upper structure work. The most frequent risk sources occur in undesirable and unacceptable risks were technical risk. Technical risk in unacceptable risk were difference between picture and actual field, inaccurate scheduling, picture problems from planner and material specification discontinuation. Technical risk in undesirable risk were mainly tools mobilization delay, working hours limitation, quality and specification inconsistency and material discontinuation. Mitigation action mostly performed in technical risk were such as communication escalation between involved parties and organization structure improvement and project administration. Largest risk ownership allocation were in contractor side. These were due to contractor as the most responsible party in construction project implementation.

Abstract

The project implementation process from planning to implementation sometimes encounters problems ranging from cost, quality and time. In the implementation process, there are obstacles, namely the soil conditions in the image do not match the actual conditions and the architectural work undergoes a design change, because the previously planned floor plan does not match the desired function. These problems lead to the need for additional costs and additional time for project completion. This study aims to identify, assess risk acceptance to determine dominant risk, mitigate risk and determine risk ownership that will be obtained as a result of these problems. The study used a qualitative descriptive method. Data were collected by means of brainstorming, interviews, observations and questionnaires. Questionnaires were distributed to 28 respondents. The results show that there are 40 valid risk identifications. There are 10 unacceptable risks and 21 undesirable risks which include dominant risk and 9 acceptable risks that do not require mitigation measures. Mitigation is carried out with 3 types of actions, namely by reducing, transferring and holding risks. The dominant risk is unacceptable, namely the occurrence of design changes more than once. Mitigation is done by ensuring the design is approved by all parties involved or who have an interest in the design to be carried out such as the owner or management of the hospital so that the design is in accordance with the desired function so that there is no design change more than once. The allocation of ownership of the largest risk is the responsibility of the contractor, namely the risk of financial problems to the contractor. The dominant risk impact on the additional cost and time added to this work has a major impact on the technical and project aspects. The total amount of additional costs is Rp. 10,825.600.000,- and the total additional time is 117 days on the project.
