A construction project is unique, specific and dynamic, and therefore projects have different levels and combinations of risks, different responses are taken to minimise those risks and different consequences affect project performance. The primary aim of this study was to analyse the impacts of perceived project risk on project performance. A path model was developed and path analysis was used to determine the relationships between risk and performance. The main survey was predominantly based on a series of interviews with project managers. A total of 22 building projects under construction were surveyed; however, only 13 projects used an 'S' curve to monitor their project performance. The study focused on these 13 projects and found that perceived project risk had a direct negative effect on monthly progress achievement, while monthly progress had a direct positive impact on schedule performance. Although project risk had no direct effect on schedule performance, this was influenced indirectly with monthly progress as the mediator between them. These findings indicate that the higher the project risk in a project, the greater the negative impact on monthly progress, and consequently the worse the schedule performance will be.Building project, path analysis, project delay, project performance, risk management,
Green Supply Chain Management (GSCM) is a concept that integrates environmental factors into the traditional SCM started from the process of design, material procurement, production, distribution and end-of life. The benefits of implementing GSCM does not only improve the company’s environmental performance, but also improve economic performance such as reducing operational costs and organizational performance such as improving the company’s image. In manufacture and automotive industry, GSCM is able to improve company performance, therefore construction industry can consider of adopting this approach. Some GSCM practices in construction sector include green design, green purchasing, green transportation, green construction, green warehousing, green recycling and facilitating green practices. The aim of this study is to identify relevant green design, green purchasing and green transportation practices as part of GSCM if applied in the construction sector. The research variables were obtained through a literature study on GSCM both in construction sector and other sectors, then the variables were validated by respondents, practitioners in construction sector. Based on three respondents, there are ten green design practices, six green purchasing practices and five green transportation practices that are relevant to the construction sector, especially building projects.
Abstract In Each activity in the oil and gas industry there are risks that could hamper the project and also there is a huge risk to the environment, social and economic. Besides oil and gas industry projects also have the potential to be dangerous to life, property and the environment, the hazard can occur if the activity is not controlled and regulated by appropriate. Basically, the disaster is certainly not possible to be planned and can occur at any time. But the circumstances of a disaster can be anticipated, that is the way to plan preventive measures and control.Based on the description above, this paper aims to discuss risk factors and risk assessment techniques that can help sustainable development programs. From the results of this study note that the risk factors of projects in the oil and gas industry is very complex, so a risk analysis must be done from various aspects, namely the project itself, the environment and disaster and should be integrated with aspects of sustainable development. As for the suggested technique is a combination of monte carlo and system dynamics. KeywordsSustainable Development, Risk Assessment Techniques, Combination Monte Carlo and System DynamicsAbstrak Dalam setiap kegiatan di industri minyak dan gas ada risiko yang dapat menghambat proyek dan juga ada risiko besar terhadap lingkungan, sosial dan ekonomi. Selain proyek industri migas juga berpotensi membahayakan kehidupan, properti dan lingkungan, bahaya bisa terjadi jika aktivitasnya tidak terkontrol dan diatur dengan tepat. Pada dasarnya, bencana ini tentu tidak mungkin direncanakan dan bisa terjadi kapan saja. Namun keadaan bencana dapat diantisipasi, itulah cara untuk merencanakan tindakan pencegahan dan pengendalian. Berdasarkan uraian di atas, makalah ini bertujuan untuk membahas faktor risiko dan teknik penilaian risiko yang dapat membantu program pembangunan berkelanjutan. Dari hasil penelitian ini diketahui bahwa faktor risiko proyek di industri minyak dan gas bumi sangat kompleks sehingga analisis risiko harus dilakukan dari berbagai aspek, yaitu proyek itu sendiri, lingkungan dan bencana dan harus diintegrasikan.
ABSTRAKAda suatu kecenderungan yang alamiah dari kelompok pemangku kepentingan untuk mencoba mempengaruhi kondisinya dalam keberhasilan proyek. Gambaran ini merupakan tantangan bagi pelaku jasa konstruksi untuk menganalisis dan mangelola berbagai perhatian dan kebutuhan dalam pelaksanaan proyek konstruksi. Tujuan dari penelitian ini adalah untuk mengetahui seberapa baik faktor-faktor yang mempengaruhi kondisi pemangku kepentingan dalam keberhasilan proyek. Faktor kondisi ketidakpastian yang datang dari pemangku kepentingan dapat diidentifikasi menjadi tiga bagian, yaitu dampak atau pengaruh yang ditimbulkan oleh pemangku kepentingan, pengikatan pemangku kepentingan dan keberdayaan psikologis pemangku kepentingan. Data didapatkan dari survei kuesioner yang berasal dari 204 responden sebagai pelaku jasa konstruksi dan dianalisis dengan menggunakan model persamaan struktural (Sructural Equation Modeling atau SEM). Hasil dari penelitian ini adalah melakukan verifikasi terhadap hipotesis yang direkomendasikan. Kondisi pemangku kepentingan yang dapat diidentifikasi menjadi dampak atau pengaruh pemangku kepentingan, pengikatan pemangku kepentingan dan keberdayaan psikologis pemangku kepentingan mempunyai pengaruh positif yang signifikan dalam keberhasilan proyek. PENDAHULUANKondisi pemangku kepentingan mempunyai pengaruh yang besar dalam keberhasilan proyek. Pemangku kepentingan merupakan beberapa kelompok atau individu yang dapat mempengaruhi atau dipengaruhi oleh pencapaian tujuan proyek. Keberhasilan proyek adalah tercapainya tujuan proyek dari sudut pandang pemangku kepentingan terkait yang secara tradisional diukur dari indikator ketepatan biaya, waktu dan kualitas sesuai kesepakatan pihak terkait. Ada suatu kecenderungan yang alamiah dari kelompok pemangku kepentingan untuk mencoba mempengaruhi kondisinya dalam keberhasilan proyek. Pengaruh kondisi atau keadaan pemangku kepentingan dalam mencapai keberhasilan proyek dapat dilihat dari dampak yang ditimbulkan oleh pemangku kepentingan (Nguyen et al., 2009), pengikatan (engagement) yang ada pada pemangku kepentingan (Ayuso et al., 2006) dan keberdayaan psikologis
