Abstract

Kondisi kritis jembatan indonesia dimana hanya 1,2% dari total 18.990 jembatan nasional yang berada dalam kondisi baik di Indonesia, menunjukkan tingginya urgensi pemeliharaan infrastruktur jembatan. Pekerjaan pemeliharaan dan perawatan menjadi aspek krusial untuk memastikan kualitas dan kelangsungan jembatan. Dalam konteks proyek konstruksi, pengembangan Work Breakdown Structure (WBS) pada tahap perencanaan dianggap sebagai elemen penting untuk menjamin kesuksesan proyek. Standar WBS berbasis risiko menjadi alat kunci dalam mengidentifikasi risiko pekerjaan dengan merinci setiap tahap hingga paket pekerjaan, efektif mengurangi dan mengendalikan potensi risiko kecelakaan kerja.Penelitian ini bertujuan mengembangkan standar WBS berbasis risiko khusus untuk pekerjaan pemeliharaan struktur atas jembatan beton. Standar yang dihasilkan terdiri dari 6 level, mencakup 27 variabel risiko dominan, dan menyajikan 3 rekomendasi respons risiko yang dapat diadopsi. Implementasi standar WBS ini diharapkan dapat meningkatkan kinerja keselamatan konstruksi, terutama dalam pengelolaan sumber daya dan pelaksanaan monitoring yang lebih baik. Sebagai panduan holistik, standar ini menjadi landasan untuk optimalisasi pekerjaan pemeliharaan, menjaga kualitas infrastruktur, dan mengurangi risiko potensial dalam proyek konstruksi. Dengan demikian, standar ini diharapkan dapat menjadi kontribusi signifikan dalam memperkuat keselamatan konstruksi, memajukan kualitas infrastruktur, dan menekan risiko potensial dalam proyek konstruksi di Indonesia.

Abstract

Construction projects have been developing from the management side year by year. One of the problems that government has been facing government construction projects over the years is the duration of the procurement process that takes too long which is hard to be implemented if the project is urgent in terms of time. This creates the urgency to seek the solutions to the problem of how to shorten the time of the procurement process. The design and build integrated contract method that unites the planning and implementation process simultaneously is able to answer these problems and shorten the procurement time of government construction projects. However, there are many disputes faced by construction projects that use integrated design contracts postproject, one of which comes from the Government Internal Supervisory Apparatus (APIP) or commonly called the Inspectorate. This is because there are several different standard between the inspectorate and the owner or contractor that has been used in the process of government construction projects Audit. This study aims to identify the standards of the audit process of the Inspectorate, analyze the risks that cause disputes, and to develop standards for risk-based audit methods for design and build-based construction projects in order to minimize disputes that occured from the inspectorate side of perspective.

Abstract

The development of housing in Indonesia, growing rapidly due to urbanization and population growth, faces challenges in terms of land, labor, and housing backlog. Despite being innovative, modular prefabrication methods are limited by unattractive designs and high costs, slowing down construction, harming the productivity of construction companies, and hindering the growth of the national construction sector. These challenges are prevalent in various countries and are influenced by low knowledge, conservative mindsets, and inhibiting regulations. In Indonesia, additional issues include a lack of mastery of modular prefabrication methods and awareness of long-term benefits. This research identified innovative risk-based applications of modular prefabrication with an ISO approach to improve project performance. The methodology employed includes a literature review, a questionnaire survey, and phased expert validation. The study found that out of 38 risk factors based on the 4 processes of implementing modular prefabrication methods, the average risk assessment is high. As a result, 5 innovations are proposed as efforts to reduce risk assessments. The research analyzed data from various literature, resulting in low inter-data connectivity. However, the processes and outcomes of this research can be relied upon for further understanding in subsequent research. This study combined proposed new innovations with those from external literature that have the potential to be applied in Indonesia for optimizing the cost efficiency of modular prefabrication methods.

Abstract

The research aims to identify the risk factors and the medium-high risks to use as the basis for the innovative method of spun pile manufacturing technology. The research uses the Delphi method to analyze and review the validity of content construction, pilot and respondent surveys, focus group discussions, and expert validation. The findings show utilizing and optimizing the technology on production machinery is influential for results on both product and service quality. The dominance category in the medium-risk technology indicates the need for improvement in the operator's competence. The result also indicates the largest medium risk is during the initial integration, Cutting and Heading at 84%, and the final step, Stressing and Spinning, at 59%. The research improvement to map the production process is related to the medium and high risks to know where and how the industry can improve. This risk-based technology and integration method is a proposed method using an approach to innovation management by reducing the risk values. Innovation by improving the standard operational procedure (SOP) was based on the relation of each activity during the integration within the risk category of medium-medium, medium-high, and high-high. We recommend improving SOP and utilizing information technology on precision for both subprocesses. Doi: 10.28991/CEJ-2024-010-11-015 Full Text: PDF
