Abstract

Disasters for plantjs usually occur due to the incompatibility of the environmental temperature with the temperature limit for plant growth, one example is the pakcoy plant which requires exposure to direct light with the air temperature not being too hot. Evaporative cooling is one of the methods to reduce temperature and increase relative humiditygreenhouse to create optimal climatic conditions for plants. One way of evaporative cooling is done by using a toolmisting (atomizer). This study aims to determine the effectiveness of usemisting in microclimate control (temperature and humidity). Greenhouse on the growth of pakcoy plants. This study used the method of direct observation which was carried out during the planting period of pakcoy plants. Based on the results obtained, the lowest average temperature was in the 30 minutes misting of 27–30 °C, at misting 20 minutes 27–31 °C, meanwhile misting for 10 minutes 27–31 °C and withoutmisting ranges from 32–38 °C. Air humidity on misting 30 and 20 minutes between 81–89 % and treatment misting 10 minutes ranged from 82–89%, while at without misting ranging from 63–77%. The use of misting as an effective control of temperature and humidity produces an average air temperature and relative humidity for the growth of pakcoy plants, namely a temperature of 26-31 °C and a humidity of 82-89%. The misting treatment with an interval of 20 minutes produced the highest number of leaves, namely 22 leaves and the misting treatment with an interval of 10 minutes produced the plants with the highest plant height and weight. The use of misting ignition time intervals has a significant effect on temperature but does not have a significant effect on humidity.

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

In smallholder cacao plantations, the protective crops used varied, so they have different effects on splash erosion. The management of land cover with a canopy of cacao and shade trees on cacao fields, aims to control of splash erosion. This study was conducted by directly measuring the magnitude of splash erosion under several levels of canopy cover. The magnitude of splash erosion was determined by measuring the depth of the eroded soil using the bottle cap method. The measurements were carried out every rain event (46 rain events with rainfall varied from 0.28 to 97.04 mm). The canopy cover level was determined by analyzing the images taken using a digital camera. The images were processed by Matlab software with closure approach. The data were analyzed by regression analysis to determine the relationship between canopy cover level and the depth of splash erosion that occurred. The results showed that the level of canopy cover influence the depth of splash erosion. In addition, this study indicates that the level of splash erosion not only influenced by the level of closure and rainfall, but also strongly influenced by the size of the leaf cover. Keywords: Cacao plantation, Canopy cover, Regression analysis, Splash erosion.
