Hydroponics is the cultivation of plants by only utilizing water without using soil. The priority is to fulfill nutritional needs for plants. The water needed in hydroponic planting is certainly less than the water requirement in cultivating plants with soil. With the current condition of the area of ??agricultural land which is decreasing along with the increase in residential land and land conversion that is increasingly unable to be controlled. If left unchecked, of course, it will be very worrying about the supply of food that can be obtained from agriculture. To avoid shortages of food, new techniques are needed in the agriculture. For example, planting techniques that can be done without using soil media, namely by hydroponic techniques. Although planting is done in water, but hydroponic techniques require little water. So that hydroponic planting is very suitable to try in areas that have minimal water supply. In order to increase agricultural production, the government strongly supports efforts to develop agricultural technology and increase science and technology. The target of this hydroponic planting can be started from the household. In general, housewives who do not work have a lot of free time, so they can develop hydroponic vegetables in their yard. The benefits that can be obtained from planting hydroponic are making beautiful gardens and the results of hydroponic planting will provide nutritional intake for the family. A better benefit is being able to provide economic benefits to support the family economy.

The research on the mortality and growth of Cryptolestes ferrugineus on IR-64 rice variety at the room temperatures of 20°C, 25°C, 30°C, 35°C and 40°C was done at the Pest Laboratory, Department of Plant Pest and Disease, Agriculture Faculty, University of Brawijaya, Malang. The results showed that C. ferrugineus could not survive at 40°C room temperature. The highest mortality of C. ferrugineus imago occurred at 40°C. Eggs produced by adult C. ferrugineus at 40°C cannot hatch into larvae, so development stops during the egg phase. The number of eggs of C. ferrugineus is produced more at room temperature 25°C than room temperature 20°C, 30°C, 35°C, and 40°C by showing the number of eggs at room temperature 25°C(85.20 items) more higher than the room temperature of 20°C(46.40 items), 30°C(55.40 items), 35°C (63.40 items) and 40°C (10.20 items)

The development of lettuce has the good prospect of supporting more people's nutrition, greater job opportunities, agribusiness development. The purpose of this study is to know how media volume affects the growth and production of lettuce. As for the benefit of this study, information to the community in particular about how the volume of soil on the growth and production of the lettuce plant can affect and provide effective soil volume information on growth and the product of the lettuce. The study used random group design methods (shelves). The study was conducted from May 26 to July 8 with six treatment, treatment of 40 g/5 kg (V1), 40 g/6 kg (V2), treatment of 40 g/7 kg (V3) treatment of 40 g/ 8 kg (V4), treatment of 40 g/9 kg (V5) and treatment of 40 g/ 10 kg (V6). In the test of media volume on the lettuce plant, application of media volume 40 g/ 5 kg soil results in the best growth on all the observable parameters: plant height (cm), leaf number (cm), root length (cm), total fresh weight (g), and total dry weight of the plant (g)

The Effect of Maja Fruit (Aegle marmelos) on Mortality of Pests of Mas Conch (Pomacea canaliculata L.) on Rice Plants inpari variety 32 The golden snail (Pomaceae canaliculata L.) is one of the important pests of rice plants. This pest attack can cause yield loss of 40% - 70% in agricultural crops. This pest also has a wide spread rate in various regions in Indonesia. The control of the golden snail in this study uses maja fruit extract which contains chemical compounds Alkaloids, saponins and tannins that are toxic to pests. This research was carried out starting from August 4 to Septmbr 3, 2021. This study aimed to determine the effect of maja fruit extract on the mortality of the golden snail (Pomaceae canaliculata L.) pest on rice plants. The experimental design used was RAK with 6 treatment concentrations, namely control, 10ml, 20ml, 30ml, 40ml, 50ml. maja fruit extract and repeated 4 times. Observations show that the higher the concentration used, the higher the content of toxic compounds that can lead to higher mortality in gold snails. The highest gold snail mortality was at a concentration of 50 ml, the lower the concentration used, the higher the percentage of damage to rice plants. The highest percentage of damage to rice plants was in the 0 treatment with a percentage of 100%.
