Abstract

The foundation reinforcement of footings is an important element in building construction that functions to transfer structural loads directly to the ground. This type of foundation is often used in buildings of less than 3 stories. The provision of this foundation can be carried out conventionally in the field using manual labor or by purchasing prefabricated products that have been processed off-site. This research aims to analyze the business potential of prefabricated footing reinforcement by comparing the time and cost efficiency between these two methods. The research methodology uses a case study approach on a residential construction project in the Jubung Area of Jember Regency by calculating work duration, labor requirements, and total material and labor costs for both scenarios. The analysis results show that off-site rebar fabrication generally offers significant time efficiency and potential cost savings, especially for medium to large-scale projects. Additionally, fabrication provides the advantage of more uniform work quality and minimizes the risk of errors in the field. Based on these findings, the foundation rebar fabrication business has good prospects in supporting the needs of modern construction projects that demand speed and cost efficiency.

Abstract

Kohesi merupakan parameter penting dalam mengevaluasi kekuatan geser tanah, namun pada tanah retak, kohesi yang terbentuk bersifat semu dan tidak permanen. Penelitian ini bertujuan untuk menganalisis kohesi semu pada tanah retak menggunakan alat uji geser langsung yang dimodifikasi, dengan mempertimbangkan variasi plastisitas tanah dan kekasaran bidang geser. Pengujian dilakukan pada sampel tanah lempung dengan konsistensi very stiff dan hard, yang merepresentasikan kondisi lereng rawan retak. Alat uji geser dimodifikasi dengan sistem tekan air 0,5 kg/cm² dan sensor tekanan mikro untuk mensimulasikan kondisi lapangan. Hasil penelitian menunjukkan bahwa kohesi semu menurun signifikan seiring meningkatnya plastisitas dan kekasaran bidang geser, dengan nilai mendekati nol pada displacement maksimum, terutama pada bidang geser kasar. Penurunan ini disebabkan oleh kehancuran struktur semu antar partikel akibat proses geser. Temuan ini mengindikasikan bahwa kohesi semu bukan kekuatan intrinsik tanah, melainkan efek sementara dari struktur tanah yang terganggu akibat retakan. Pemahaman ini krusial untuk desain geoteknik dan evaluasi stabilitas lereng di wilayah rawan longsor.
