"Pekerjaan rigid pavement pada proyek jalan tol Trans Sumatera ruas Pekanbaru-Padang merupakan salah satu tahap konstruksi yang sangat krusial dalam menjamin kualitas dan keberlanjutan jalan tol. Daftar ketidaksesuaian yang tercatat dalam Berita Acara (BA) PHO akibat berbagai faktor, seperti aspek teknis, keterbatasan sumber daya, hingga pengelolaan proyek yang kurang optimal. Penelitian ini bertujuan untuk mengidentifikasi jenis-jenis Defect List yang sering terjadi pada perkerasan rigid pavement, merumuskan langkah-langkah efektif untuk meminimalkan terjadinya Defect List, serta menganalisis risiko yang muncul akibat deffect rigid. Hasil penelitian menunjukkan bahwa penerapan strategi antisipasi mampu mengurangi jumlah Defect List. Pada lokasi yang penulis lakukan yaitu STA 58+400 hingga STA 60+200, jumlah Defect List yang ditemukan terdiri atas 9 defect minor dan 9 defect mayor. Angka ini lebih rendah dibandingkan dengan dua lokasi lainnya, yakni STA 55+200 hingga STA 57+000 dengan 15 defect minor dan 20 defect mayor, serta STA 60+200 hingga STA 62+000 yang mencatat 12 defect minor dan 32 defect mayor. Perbedaan ini diduga disebabkan oleh kurangnya penerapan langkah-langkah preventif pada lokasi-lokasi tertentu. Melalui penelitian ini, diharapkan menjadi panduan dalam pelaksanaan pekerjaan rigid pavement, sehingga kualitas konstruksi jalan rigid pavement dapat ditingkatkan dan diharapkan berkontribusi dalam pengembangan konstruksi jalan di masa mendatang.

The rigid pavement work on the Trans Sumatera toll road project section, Pekanbaru-Padang, is one of the most crucial construction stages in ensuring the quality and sustainability of the toll road.  The list of discrepancies recorded in the PHO Minutes of Meeting (MoM) is due to various factors, such as technical aspects, resource limitations, and suboptimal project management. This research aims to identify the types of Defect Lists that frequently occur in rigid pavement, formulate effective steps to minimize the occurrence of Defect Lists, and analyze the risks that arise due to rigid defects. The research results show that the implementation of anticipation strategies can reduce the number of Defect Lists. At the location I examined, namely STA 58+400 to STA 60+200, the number of defects found consisted of 9 minor defects and 9 major defects. This figure is lower compared to the other two locations, namely STA 55+200 to STA 57+000, which had 15 minor defects and 20 major defects, and STA 60+200 to STA 62+000, which recorded 12 minor defects and 32 major defects. We suspect that the lack of implementation of preventive measures at certain locations is the cause of this difference. This research aims to guide the implementation of rigid pavement work, enhancing its quality and potentially contributing to the future development of road construction. "

"The pavement of the nailed-slab system has been proposed as an alternative solution for addressing the rigid pavement problem in soft soils. This system is used for developing a rigid pavement. The simple method of using an equivalent modulus of subgrade reaction (k’) in nailed-slab system analysis was proposed by a previous researcher. This modulus consists of the modulus of subgrade reaction from a plate load test (k) and an additional modulus of subgrade reaction due to pile installing (k). The additional modulus of subgrade reaction has been proposed by some authors. The displacement factor was used in determining the additional modulus of subgrade reaction. This factor is difficult to define. In this research, the prototype test of a nailed slab with single-pile installation was conducted to learn the validation of the theory of the additional modulus of subgrade reaction on a full-scale dimension. The prototype was constructed on soft clay, and the connection between the pile and slab was perfect monolithically. This system was loaded by centric load. A new curve of the displacement factor is proposed. Calculated deflections based on this curve were compared to the observed deflection and resulted in good agreement with the observation. Hence, it can be used in preliminary design."

"Penelitian ini ditujukan untuk mengetahui sejauh mana etsa dan gerinda pada permukaan semen gelas ionomer mempengaruhi kekuatan ikatan antara semen gelas ionomer dengan resin komposit. Sampel berupa lempeng semen gelas ionomer sebanyak 40 yang dibagi menjadi 4 kelompok, setiap kelompok terdiri dari 10 buah yang masing masing mendapat perlakuan sebagai berikut: kelompok I permukaan semen gelas ionomer dietsa dengan asam fosfat 37% selama 30 detik, kelompok II digerinda , kelompok III dietsa dan digerinda, dan kelompok IV sebagai kelompok kontrol tidak dietsa dan tidak digerinda.Analisa statistik dengan anova 2 arch ternyata ada perbedaan yang bermakna antar kelompok pada (p=?7.05). Sedang analisa statistik dengan uji t dengan p=o,05 menunjukkan ada perbedaan bermakna antara kelompok I-IV dan II-IV.Disimpulkan bahwa dengan etsa asam selama 30 detik pada permukaan gelas ionomer diperoleh ikatan yang terbaik antara semen gelas ionomer dengan resin komposit."
