Abstract
Sistem drainase merupakan elemen penting dalam pembangunan infrastruktur perkotaan, khususnya di wilayah padat penduduk seperti Kota Samarinda. Efektivitas saluran drainase sangat dipengaruhi oleh metode konstruksi yang digunakan, sehingga pemilihan metode yang tepat menjadi faktor penting dalam mencapai hasil yang efisien secara waktu dan biaya. Penelitian ini membahas perbandingan metode precast dan cast in situ pada pekerjaan saluran drainase di Jalan Flamboyan, Kelurahan Loa Buah, Kota Samarinda, yang masing- masing memiliki karakteristik, keunggulan, serta keterbatasan tersendiri. Data penelitian diperoleh melalui observasi lapangan serta dokumen proyek. Metode precast dikenal unggul dalam mutu beton dan kecepatan pemasangan, sementara cast in situ lebih fleksibel dalam penyesuaian bentuk namun memiliki durasi pekerjaan yang lebih panjang dan rentan terhadap faktor cuaca serta kualitas tenaga kerja. Hasil penelitian menunjukkan bahwa metode precast menyelesaikan pekerjaan dalam 86 hari dengan biaya sekitar Rp 9,043 miliar, sedangkan metode cast in situ membutuhkan 200 hari dengan biaya sekitar Rp 7,69 miliar. Analisis efisiensi menunjukkan bahwa precast unggul dalam waktu dengan efisiensi 57 % dan cast in situ memberikan efisiensi biaya sebesar 15 % setelah penyesuaian analitis. Secara keseluruhan, metode precast lebih direkomendasikan untuk proyek drainase berskala panjang dengan akses alat berat yang memadai, sementara metode cast in situ tetap relevan untuk lokasi dengan kebutuhan desain yang lebih fleksibel.
