Abstract

Apron B Bandar Udara Djalaluddin Gorontalo merupakan area strategis untuk pergerakan pesawat yang direncanakan diperluas sebesar 38.016 m² untuk mendukung status Embarkasi Haji Penuh (EHP) sehingga harus mampu melayani Pesawat Boeing 777 300ER. Salah satu komponen penting perkerasan kaku adalah lapisan stabilized base, di mana dua material yang umum digunakan yaitu lean concrete dan cement treated base (CTB) harus dievaluasi untuk menentukan opsi yang paling optimal dan efisien dari segi struktur dan ekonomi. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif komparatif, yang dilakukan dengan mengolah data numerik serta membandingkan dua jenis material stabilized base melalui simulasi menggunakan software FAARFIELD. Analisis dilakukan untuk memperoleh hasil perbandingan ketebalan struktur perkerasan, nilai PCN, serta estimasi biaya konstruksi. Hasil analisis menunjukkan bahwa struktur dengan lean concrete memiliki total ketebalan 793 mm dan menghasilkan nilai PCN sebesar 117 R/B/W/T, sedangkan struktur dengan CTB memiliki total ketebalan 795 mm dengan nilai PCN 118 R/B/W/T. Dari sisi biaya, rencana anggaran biaya untuk struktur perkerasan kaku apron B dengan menggunaan lean concrete pada lapisan stabilized base mencapai Rp 96,406,624,950, sedangkan penggunaan CTB lebih ekonomis sebesar Rp 95,350,273,103. Kedua alternatif memenuhi syarat kekuatan struktur (PCN > ACN), namun CTB menawarkan kombinasi terbaik antara performa dan efisiensi biaya untuk lapisan stabilized base Apron B.

Abstract

Corrosion is one of the main problems that can reduce the quality and service life of steel materials in the railway industry, especially on train roofs made of SS400 mild steel. This study aims to examine the effectiveness of adding natural inhibitors from corn cob ash to epoxy primer paint in inhibiting the rate of corrosion and increasing the adhesive strength of the paint. The inhibitor was made through a process of extracting silica from corn cob ash and mixing it into the primer paint at various concentrations. Fourier Transform Infra Red (FTIR) testing was used to identify the silica content in the inhibitor, while testing was carried out on the adhesive strength using an adhesion tester and the corrosion rate using the weight loss test method in HNO₃ solution. The results showed that the addition of corn cob ash inhibitor formed a protective layer on the metal surface, improved paint adhesion, and significantly reduced the corrosion rate. This study demonstrates that the use of agricultural waste such as corn cobs as a natural inhibitor is an innovative, economical, and environmentally friendly solution for controlling corrosion in steel materials in the railway industry.
