Abstract

Projects at the brownfield location cannot be separated from potential hazards related to geotechnical conditions and the existing project site. The construction phase is carried out at a location in the middle of an already operating factory. Lack of understanding of site characteristics and minimal use of the technology used can result in the project not meeting what was expected. This study aims to identify brownfield risk events during the construction phase of the PLTGU project development in Indonesia. This research uses quantitative and qualitative methods with a case study approach. Primary data were collected using documentation, field observations, survey questionnaires and structured interviews. The results of the study identified 23 (twenty three) and 6 (six) main risks based on the rankings, namely: 1) Groundwater level risk, 2) Location infrastructure damage, 3) Flood risk, 4) Structural damage and structural settlement, 5) Land subsidence, 6) Leakage of existing underground pipes. risks affecting project performance during the construction phase. The results of the study reveal that these risk events are risks that must be managed by project management during the construction phase.

Abstract

Failed tender often occurs in the process of procuring in government agencies. In BP2JK Central Java, the number of failed tender packages in the last 3 years is quite high, namely 10-35%. This study aims to analyze the risk of failed tender in the BP2JK area. The method used in this study is descriptive quantitative, where the analysis was based on historical procurement data in the last 4 (four) years and also on a questionnaire to 90 respondents consisting of 28 Pokja and 62 PPK in the BP2JK Central Java area. The results of the analysis show that there are 12 identified risks. If sorted from the highest risk level, these include: selection document errors, evaluation process errors, procurement implementation that was not on schedule, no participants passed the evaluation, bids did not meet requirements, procurement process errors, more than 1 (one) document uploaded, overqualified, owner estimate too low, participants did not show evidence, e-procurement system was hacked and price negotiations were not reached. While the method was frequently used as a risk response is reducing the possibility of a risk occurring, and followed by reducing the impact of risk, sharing risk, avoiding risk or accepting risk.

Abstract

Penerapan standard bangunan tahan gempa baru pada penelitian ini adalah bagian dari mekanisme kebijakan teknis dan harmonisasi kepentingan dari para praktisi gedung di daerah. Persoalan teknis di lapangan menuntut adanya integrasi komitmen antara praktisi gedung dan pemilik proyek. Jika suatu penerapan standard bangunan terjadi saat gedung sedang dibangun maka perlu mekanisme kebijakan yang dapat mengharmonisasi kepentingan teknis dan administrasi proyek. Penelitian ini merupakan bukti empirik bagaimana mekanisme kebijakan retrofit bangunan pasca penerapan SNI bangunan tahan gempa baru diterapkan pada bangunan rumah sakit umum di Jawa Barat. Metode penelitian yang digunakan adalah menggunakan simulasi model struktur dan wawancara semi-structured dengan enam praktisi gedung yang telah berpengalaman antara 15-25 tahun. Hasil simulasi model struktur diperoleh bahwa beberapa elemen struktur harus dilakukan retrofit untuk meningkatkan kapasitas terhadap beban gempa baru yang relatif meningkat dua kalinya dari standar gempa lama. Hasil penelitian menunjukkan bahwa, keberhasilan penerapan standard gedung tahan gempa baru dipengaruhi oleh mekanisme komunikasi dan pengalaman kontraktor yang memadai pada eksekusi di lokasi. Interaksi antara pemilik proyek, kontraktor, dan tim manajemen konstruksi adalah bentuk mekanisme yang bisa dikembangkan terutama bagi praktisi gedung di daerah dengan keterbatasan sumber daya teknologi dan keterampilan.
