Ferrocement is a mortar made from a homogeneous mixture of cement, sand, and water reinforced with reinforcement covered with continuous and tightly woven wire. The specification aspect is carried out by testing the mortar compressive strength at the ages of (3, 7, 14, 21, and 28 days) and water absorption testing at the age of 28 days after curing. Water loss testing is carried out by observing the ferrocement irrigation channel on a laboratory scale at the age of 28 days. The cost and time aspects of the work implementation are analyzed based on the Circular Letter of the Directorate General of Construction Development Number 33 of 2023. The results of the compressive strength study of stone masonry mortar at the age of 28 days for Type N were 107.41 kg/cm2; Type M was 263.77 kg/cm2; and ferrocement was 361.66 kg/cm2. The water absorption value of Type N mortar was 17.62%; Type M was 16.71%; and ferrocement was 16.26%. This means that the mortar mixture plan for Type N, Type M, and Ferrocement met the required specifications and criteria. The water loss of the laboratory-scale ferrocement channel was 3.66% and there was no seepage or water droplets on the surface of the test object. These results indicate that ferrocement is watertight. The cost of implementing the irrigation channel work using river stone masonry is Rp. 454,577,440.00 and ferrocement Rp. 410,802,000.00. The implementation time for the irrigation channel work using river stone masonry is 65 working days and 55 working days for ferrocement. These results show that ferrocement construction is more efficient than river stone masonry in terms of specifications, costs and time.
