Published: March 2021

Reinforced concrete beams as structural elements that are often found are elements that are quite large in their role in bearing loads. Judging from the function of support as a bearer of tensile force, it is possible if the reinforced concrete beams are made with different numbers and areas of reinforcement. Reinforcement bundles are used if there is a cross-sectional dimension limitation without the distance between the reinforcement conditions being met. Beams with 2 reinforcement bundles are made to see the flexural capacity obtained. With the dimensions of the beam 150 mm x 200 mm x 1050 mm, a bundle of 2 reinforcement with a diameter of 10 mm is mounted on the tensile section of reinforced concrete beams. With a four-point bending test, a nominal bending moment is obtained. Single-section square cross-section analysis with cross-sectional area obtained using the equivalent diameter of the reinforcement bundle compared to the flexural test results. The bending moment capacity between experiment and analysis obtained the appropriate results. The bending capacity value of the two reinforcement bundles is still large so that the bending failure has not been reached.

Based on Malang Regency agriculture data in 2017 presented by the Head of the Agriculture and Food Crops and Horticulture Office (DPTPH), there was a 2.5% decrease in yields. One hectare of paddy land can produce 7.71 tons during normal weather, but currently only produces 6.9 tons per hectare. Three farmers’ groups in Malang Regency (2018), are of the opinion that the current weather greatly influences crop failure. Weather prediction used so far using conventional benchmarks for planting, is no longer relevant to current reality. These estimates are often incorrect, resulting in crop failures, which have an impact on the farmer’s economy. This study aims to make the application of weather prediction systems and recommendations for suitable planting varieties based on data on temperature, humidity, time of sun exposure, wind speed, and rainfall using Backpropagation ANN method. Data used for Karangploso District weather prediction from 2009-2018. While the variables used in the application of Backpropagation ANN: temperature, humidity, time of sun exposure, wind speed, and rainfall. For output, the prediction of rainfall in the next 12 months and planting of varieties in accordance with the predicted rainfall, OPT and land type. From the calculation results of this application the MSE error value of 0.0299 is obtained.
