Abstract

Many lettuce plants are grown hydroponically because they produce better quality.The problem with hydroponic systems is that the plant roots are submerged in the nutrient solution, therefore it will rot easily due to lack of oxygen in the root area. To overcome this problem, hydroponics with microbubble technology is applied. This research aims to determine the performance of the ventury dual nozzle in producing microbubbles and its effect on the growth and productivity of lettuce plants. This research was carried out by assembling a hydroponic system equipped with a ventury model aerator, measuring bubble characteristics using the image processing method and analyzing plant parameters using variance analysis. Ventury nozzle with a pressure of 260 KPa produces microbubbles measuring between 200 - 300 m and a spray range of 6.13 cm with a resistance of around 3.2-4.6 seconds. The use of a ventury nozzle model aerator increases dissolved oxygen and distributes it evenly in the hydroponic nutrient solution, thereby increasing the growth and yield of lettuce plants.

Abstract

Irrigation plays a crucial role in agriculture, particularly in Indonesia, by ensuring a stable water supply for rice fields, thereby enhancing crop productivity and optimizing water use. The efficiency of an irrigation network directly impacts water distribution, making it essential to assess system performance regularly. This study evaluates the performance of the tertiary irrigation system in the Bulutimorang Irrigation Area, Sidrap Regency, and maps the condition of its existing physical infrastructure. The research was conducted from May to July 2023 and involved field surveys, network tracing, and interviews with farmers, sluice gate officers, and irrigation personnel (juru/mantri). Data were analyzed to validate key performance indicators based on the Regulation of the Minister of PUPR No. 12/PRT/M/2015. The results indicate that the tertiary irrigation network in the Bulutimorang Irrigation Area is functioning well, with an overall performance score of 72.06%. These findings highlight the need for continued maintenance and improvement strategies to sustain efficient irrigation management in the region.
