Sustainable Self-Compacting Concrete: The Role of Limestone Powder as A Cement Replacement

JURNAL TEKNIK SIPIL CENDEKIA (JTSC) doi:10.51988/jtsc.v7i2.505

The excessive use of cement in concrete production contributes significantly to environmental impacts, particularly CO? emissions. One potential solution is the partial replacement of cement with limestone powder in self-compacting concrete (SCC). This study aimed to investigate the effect of limestone powder as a partial cement replacement on the fresh properties and compressive strength of SCC. Limestone powder was used at replacement levels of 0%, 6%, 9%, 12%, and 15% by weight of cement. The fresh properties of SCC were evaluated using slump flow, V-funnel, and L-box tests, while compressive strength tests were conducted to assess hardened performance. The results showed that SCC mixtures containing up to 9% limestone powder satisfied the SCC workability requirements. The optimum performance was achieved at 6% limestone powder replacement, which produced a slump flow diameter of 600 mm and compressive strength of 29.58 MPa, exceeding the design strength target of 25 MPa. Higher replacement levels reduced both workability and compressive strength, with the 15% mixture failing to meet acceptable performance criteria. These findings indicate that limestone powder can be effectively utilized as a sustainable partial cement replacement in SCC at moderate replacement levels while maintaining satisfactory fresh and hardened properties.

TINJAUAN SISTEMATIS KOMPARASI PCI DAN VISI KOMPUTER UNTUK EVALUASI KERUSAKAN JALAN

RADIAL: Jurnal Peradaban Sains, Rekayasa dan Teknologi doi:https://doi.org/10.37971/radial.v14i1.577

This study aims to conduct a comparative analysis of the conventional Pavement Condition Index (PCI) method and a computer vision-based approach in evaluating road pavement damage in Indonesia. The method used was a Systematic Literature Review (SLR) based on the PRISMA 2020 guidelines. Data were collected through a structured search of the Scopus and Google Scholar databases, identifying 27 selected studies that met the inclusion criteria. The results show that PCI has high accuracy and is internationally recognized for evaluating 20 types of damage, but it requires significant time, cost, and manpower and involves subjectivity. Conversely, computer vision using deep learning algorithms can provide fast, objective, and scalable results with 76–95% accuracy, although it is still limited to specific types of damage and is influenced by environmental factors. This study recommends a hybrid approach that integrates both methods, along with the use of low-cost technologies, such as smartphones and GIS-based UAVs, to support more efficient road infrastructure maintenance in Indonesia.

Sosialisasi dan Pengenalan Forensik Engineering Sebagai Upaya Peningkatan Kompetensi Mahasiswa Teknik di Universitas Gorontalo

JGen doi:10.60126/jgen.v4i1.1442

Forensik engineering merupakan bidang multidisiplin dalam teknik yang berperan penting dalam mengidentifikasi penyebab kegagalan struktur, infrastruktur, maupun sistem rekayasa. Namun demikian, pemahaman mahasiswa teknik terhadap konsep dan penerapan forensik engineering masih relatif terbatas, khususnya di lingkungan Universitas Gorontalo. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan dan kompetensi mahasiswa teknik melalui sosialisasi dan pengenalan forensik engineering sebagai bagian dari penguatan kapasitas akademik dan profesional. Metode pelaksanaan kegiatan meliputi penyampaian materi secara interaktif, diskusi studi kasus kegagalan struktur, serta evaluasi pemahaman peserta melalui kuesioner pre-test dan post-test. Sasaran kegiatan adalah mahasiswa Fakultas Teknik Universitas Gorontalo dari berbagai program studi. Hasil kegiatan menunjukkan adanya peningkatan signifikan pada pemahaman peserta terhadap konsep dasar, ruang lingkup, dan peran forensik engineering dalam dunia keteknikan. Selain itu, kegiatan ini juga menumbuhkan kesadaran mahasiswa akan pentingnya aspek keselamatan, etika profesi, dan tanggung jawab insinyur dalam praktik rekayasa. Dengan demikian, sosialisasi dan pengenalan forensik engineering terbukti efektif sebagai upaya peningkatan kompetensi mahasiswa teknik dan diharapkan dapat menjadi dasar pengembangan kurikulum maupun kegiatan akademik lanjutan di Universitas Gorontalo.
