Abstract

Indonesia's Agriculture is a strategic sector in increasing economic growth. One of the efforts to increase agricultural production in Indonesia is through technology. Smart farming models can be developed to improve the efficiency and effectiveness of farmland management. The monitoring and watering regulation system using IOT has many benefits, including time efficiency, work effectiveness, remote operation, simplicity, and better irrigation accuracy. In this study, the Smart Farming Device was placed in a coastal area with a hot climate in the chili garden. The experiment was conducted 9 hours from 08.00 – 17.00 WIB (West Indonesian Time). The Smart Farming Device works in a modular manner controlled remotely by the internet network, which works by energy converted from the sunlight. The use of types of sensors and the sensors placed on the farmland will determine the accuracy of the information received by farmers. From the sensors parameter, we found that spraying water to the farmland does not raise the soil moisture. A wind speed sensor needs to be added to the device to determine the effect of wind blow on the environmental parameters of the farmland. The irrigation method looks more promising for improving soil moisture conditions than the method of spraying water through the air.

Abstract

Bending is a process of mixing materials which results in convexity while other parts become concave due to the influence of force or bending moment. During the bending process, it results in different pipe strains, which cause permanent strains. The annealing process (heat treatment) is a process for changing the metal structure by heating the specimen. The aim of this research is to analyze the material hardness of the ASTM 304 L stainless steel long elbow pipe after the annealing process is carried out, the test is carried out at various angles, namely (0°, 90°, 180°, and 270°) using the Hardness Tester. The method used in this research is an experimental method, a research procedure carried out to determine the effects of the annealing treatment given to the material. The research results from the 0° angle have a material hardness of 156 HB, from the 90° angle the material hardness is 140 HB, from the 1800 angle the material hardness is 164 HB, from the 2700 angle the material hardness is 159 HB, the conclusion is that the annealing process and the inner angle of the long elbow pipe has a significant influence on the hardness of stainless steel materials. Keywords: elbow pipe, annealing, hardness tester.
