Industri semen menyumbangkan sekitar 8% emisi karbondioksida di dunia yang signifikan memberikan dampak buruk bagi lingkungan<em>. Ground Granulated Blast Furnace Slag</em> (GGBFS), yang merupakan limbah indutri padat, dapat dimanfaatkan menjadi salah satu alternatif bahan substitusi sebagian semen untuk membuat material konstruksi yang ramah lingkungan. Penelitian ini bertujuan untuk mengetahui pemanfaatan limbah industri yaitu GGBFS sebagai substitusi semen pada mortar mutu tinggi untuk membuat <em>self-compacting mortar</em> (SCM). Variasi substitusi sebagian semen dengan GGBFS yang diambil untuk membuat SCM adalah sebesar 0%, 10% dan 20%. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh dari sustitusi sebagian semen dengan GGBFS terhadap kekuatan tekan dan sorptivitas. Rasio air terhadap binder (w/b) diambil sebesar 0,3. Berdasarkan hasil yang telah diperoleh, kekuatan tekan SCM pada variasi 20% mencapai 61,8 MPa pada umur 28 hari. Pada campuran yang sama, diperoleh nilai <em>initial absorption</em> sebesar 0,0076 dan <em>secondary absorption</em> sebesar 0,0024 yang mengindikasikan campuran dengan substitusi sebagian semen dengan GGBFS sebesar 20% memiliki tingkat penyerapan air yang rendah dan memiliki durabilitas yang baik. Pemanfaatan GGBFS sebagai substitusi sebagian semen memiliki manfaat yang positif untuk menciptakan material konstruksi yang ramah lingkungan.</p>2024-10-28T00:00:00+07:00Copyright (c) 2024 Nenny Samudra, Herry Suryadi Djayaprabha, Diana Darapuspahttps://journal.unpar.ac.id/index.php/josc/article/view/8109Investigation of Community Engagement in Sustainable Construction Projects: Case Studies from Nigeria 2024-09-20T07:52:45+07:00Hyginus C.

Using a mixed-methods approach, data were collected through interviews, surveys, and document analysis. The research identifies significant variations in engagement practices, with Lagos showing high engagement levels, leading to greater community acceptance and better environmental outcomes. Key success factors include strong leadership, adequate funding, and effective communication, while challenges such as socio-cultural barriers and political interference were noted. The findings emphasize the importance of sustained, tailored engagement strategies to enhance project sustainability and community support. This study contributes to the literature by providing empirical data on the long-term impacts of community engagement, offering insights for policy makers and project managers to improve community participation in sustainable construction.</p>2024-10-28T00:00:00+07:00Copyright (c) 2024 Hyginus Unegbu, Danjuma Saleh Yawas, Bashar Dan-asabe, Abdulmumin Akoredeley Alabihttps://journal.unpar.ac.id/index.php/josc/article/view/8112An Investigation of Renewable Energy Solutions for Off-Grid Sustainable Housing in Rural Nigeria2024-08-22T15:49:09+07:00Hyginus C. O. Unegbuchidieberehyg@gmail.comDanjuma Saleh Yawasdyawas@yahoo.comBashar Dan-asabebashar.dan.asabe@gmail.comAbdulmumin Akoredeley Alabiabdulmm2001@gmail.com<p>This study examines the adoption of renewable energy solutions for off-grid sustainable housing in rural Nigeria, focusing on the types of technologies implemented, their impact on living standards, and the factors influencing adoption. A mixed-methods approach, combining quantitative survey data from 340 households with qualitative interviews and case studies, reveals that solar photovoltaic (PV) systems are the most widely adopted renewable energy technology, significantly enhancing health outcomes, economic activities, and educational opportunities. Multivariate regression analysis identifies income, education level, and awareness as key predictors of renewable energy adoption, with coefficients of 0.345, 0.267, and 0.453, respectively, suggesting that higher income, education levels, and awareness substantially increase the likelihood of adopting renewable energy solutions. Structural Equation Modeling (SEM) illustrates that awareness mediates the impact of income and education on adoption, which, in turn, contributes to improved living standards. The study underscores the need for comprehensive policies, community engagement, capacity building, financial support, and effective monitoring and evaluation frameworks to encourage renewable energy adoption in rural Nigeria. These findings highlight the multifaceted benefits of renewable energy, including improved health, economic growth, and educational outcomes, while suggesting that addressing identified barriers can enhance the effectiveness and scalability of renewable energy initiatives.</p>2024-10-28T00:00:00+07:00Copyright (c) 2024 Hyginus Unegbu, Danjuma Saleh Yawas, Bashar Dan-asabe, Abdulmumin Akoredeley Alabihttps://journal.unpar.ac.id/index.php/josc/article/view/8114Climate Resilience in Nigerian Construction: A Systematic Review of Strategies and Outcomes2024-09-20T07:58:10+07:00Hyginus C. O. Unegbuchidieberehyg@gmail.comDanjuma Saleh Yawasdyawas@yahoo.comBashar Dan-asabebashar.dan.asabe@gmail.comAbdulmumin Akoredeley Alabiabdulmm2001@gmail.com<p>Climate resilience in the construction sector is critical for ensuring the durability and sustainability of infrastructure amidst the increasing impacts of climate change. This study systematically reviews climate resilience strategies in the Nigerian construction sector, evaluating their effectiveness and outcomes. A comprehensive literature search yielded 50 peer-reviewed journal articles, conference papers, and official reports, focusing on design innovations, material selection, policy frameworks, and case studies across Nigeria's diverse climatic zones. Key findings indicate that strategies such as flood barriers, green roofs, and sustainable materials are effective in mitigating climate risks, although challenges such as financial constraints, regulatory gaps, and lack of awareness persist. The study highlights the importance of community involvement, government support, and technological innovation in successfully implementing resilience measures. Comparative analysis with global best practices underscores the need for integrated approaches tailored to Nigeria's unique context. The study concludes with recommendations for future research, emphasizing the need for longitudinal studies, cross-regional comparisons, and the integration of traditional knowledge. Policy implications include the development of comprehensive regulatory frameworks and public-private partnerships to enhance the sector's adaptive capacity. This research provides valuable insights and practical recommendations for enhancing climate resilience in Nigeria's construction industry, contributing to broader goals of sustainable development and climate adaptation.</p>2024-10-28T00:00:00+07:00Copyright (c) 2024 Hyginus Unegbu, Danjuma Saleh Yawas, Bashar Dan-asabe, Abdulmumin Akoredeley Alabihttps://journal.unpar.ac.id/index.php/josc/article/view/8157Analisis Faktor-Faktor Penyebab Cost Overruns Proyek Konstruksi Gedung: Kajian Literatur Sistematis2024-08-22T15:56:14+07:00Friedrich Adescanius Suryawinata8102201029@student.unpar.ac.id<p>Industri konstruksi merupakan salah satu kekuatan dalam perekonomian dunia, sehingga apabila terdapat masalah dalam industri konstruksi maka menyebabkan masalah pada perekonomian dunia. Salah satu masalah yang biasa terjadi adalah masalah pembengkakan biaya. Penelitian ini dilakukan untuk mengetahui faktor dominan penyebab <em>cost overruns</em> pada proyek konstruksi dan memitigasi risiko terjadinya <em>cost overruns</em> pada proyek konstruksi gedung. Metode yang digunakan adalah <em>systematic literature review</em> untuk mengumpulkan, dan menguji secara kritis hasil dari berbagai kajian penelitian sebelumnya untuk menjawab topik yang ingin didalami. Artikel yang digunakan sebanyak 15-20 artikel yang difokuskan pada penelitian tahun 2010-2024 dan berfokus pada pembengkakan biaya pada konstruksi gedung. Dari hasil penelitian teridentifikasi bahwa terdapat tujuh faktor dominan yang menyebabkan <em>cost overruns</em> yaitu: permasalahan desain, <em>force majeure</em>, fluktuasi harga, kesalahan estimasi biaya, pekerjaan tambah, pekerjaan ulang dan inflasi. Mitigasi risiko untuk menghindari atau mengurangi terjadinya <em>cost overruns</em> pada proyek konstruksi gedung dilakukan dengan cara: meningkatkan anggaran untuk kontrak pengawas, mempekerjakan pengawas yang kompeten dari negara maju, menggunakan pengawas yang profesional dan kompeten, melakukan estimasi biaya dengan tepat, memberikan harga penawaran yang jelas, menerapkan manajemen proyek dengan baik, mempererat komunikasi dan kerja sama, melakukan penjadwalan dengan baik sebelum proyek dimulai dan menghindari perselisihan antar pihak yang terlibat dalam proyek.</p>2024-10-28T00:00:00+07:00Copyright (c) 2024 Friedrich Adescanius Suryawinata
