Tinjauan Kinerja Simpang Tak Bersinyal Jl. AA Wahab, Jl. Sun Ismail, Dan Jl. Kh Hutu Badu Di Kabupaten Gorontalo

Penelitian ini berjudul "Tinjauan Kinerja Simpang Tak Bersinyal Jl. A. A. Wahab, Jl. Sun Ismail, dan Jl. KH Hutu Badu" yang dianalisis menggunakan metode pedoman Jalan Indonesia 2023. Penelitian ini bertujuan untuk mengevaluasi kinerja persimpangan tak bersinyal di Kabupaten Gorontalo berdasarkan data survei lapangan dan analisis perhitungan. Hasil penelitian menunjukkan bahwa tingkat arus lalu lintas tertinggi terjadi pada jam 17.00-18.00 WITA. Kinerja persimpangan dinilai dari beberapa indikator utama: nilai derajat kejenuhan (Dj) sebesar 0,501, yang masih lebih kecil dari batas maksimum 0,85; tundaan lalu lintas sebesar 5,86 detik, yang berada di bawah ambang batas 10 detik; dan nilai peluang antrian sebesar 17,92%, yang berada di bawah batas aman 35%. Kesimpulan dari analisis ini mengindikasikan bahwa kinerja persimpangan tersebut masih berada dalam kategori yang baik dan aman menurut pedoman yang berlaku.

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

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

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.
