This study aims to determine the effectiveness of antibacterial pineapple peel extract (Ananascomosus. L) on Ralstonia solanacearum growth. Pineapple peel extract (Ananas comosus.L) containsantibacterial compounds of bromelin and tannin enzymes that are able to inhibit the growth of plantcausing bacteria, Ralstonia solanacearum. Ralstonia solanacearum bacteria will be given 5treatments with pineapple peel extract 10%, 30%, 60%, 100% and positive control Streptomicinsulfate 0.01%, each repeated 5 times. The test was performed by adding 100μl of Ralstoniasolanacearum suspension which was diluted into 15ml Tetrazolium chloride agar medium which wasgiven 100 ml of pineapple peel extract. The results showed that the treatment of pineapple peel extracthad a significant effect on the growth of Ralstonia solanacearum. The average number of treatedbacteria 60% (4x107 CFU), 100% (8x106 CFU) and Streptomicin sulfate 0.01% (4x106 CFU) wassignificant (P <0.01) higher than the number of bacteria treated by concentration 10% (1.79x108)and 30% (1.27x108). Consentration 100% pineapple peel extract (Ananas comosus.L) is the mosteffective in inhibiting the growth of Ralstonia solanacearum. Thus it can be concluded that pineapplepeel extract (Ananas comosus.L) is effective as an antibacterial Ralstonia solanacearum.

A study has been conducted to compare some varieties of planting media on red lettuce (Lactuca sativa var crispa L), the variables observed in this study are wet weight and chlorophyll content. This research was conducted by using complete randomized design (RAL) consisting of 5 variants of planting medium (Rockwool (as control), cocopeat, fuel husk, cotton and sponge) with 4 replications. The results showed that rockwool planting media had significant effect (P <0,05) on wet weight of red lettuce plant (Lactuca sativa var. Crispa L). Then, on the results of chlorophyll content test, it was found that the variation of burning husk medium media on red lettuce plant had significant effect (P <0,05) to chlorophyll a and total chlorophyll, while in chlorophyll b the result obtained was not significantly different (P> 0, 05). The results of this study indicate that the treatment of rockwool planting media in red lettuce plant growth is effective to increase wet weight and the treatment of burning husk medium media can increase the chlorophyll content of red lettuce plants namely chlorophyll a and total chlorophyll red lettuce plants (Lactuca sativa var. Crispa L.). Keywords: red lettuce, wet weight, test of chlorophyll content a, chlorophyll b, total chlorophyll

The aim of this study was to compare the organic fertilizer of azolla pinnata and banana peel and a combination of azolla pinnata and banana peel with the same concentration of 800 ppm to the weight of harvest and the chlorophyll content of ground spinach (Ipomoea reptans Poir.). The experiment was carried out experimentally using a completely randomized design with control treatment, 800 ppm azolla pinnata, 800 ppm banana skin and a combination of azolla pinnata and banana peels 800 ppm which were repeated 6 times each. The application was carried out by pouring 800 ppm of azolla pinnata, 800 ppm of banana peel and a combination of azolla pinnata and 800 ppm banana peel on each gutter. The results showed that azolla pinnata and banana peel nutrition had a significant effect (P <0.05) on harvest weight and chlorophyll content of ground spinach plants (Ipomoea reptans Poir.). Nutrition azolla pinnata and banana peel with a concentration of 800 ppm can increase the weight of the land spinach (Ipomoea reptans Poir.) Which has the highest average. In testing the chlorophyll content, the results of chlorophyll a content, chlorophyll b content and the highest total chlorophyll content was found in azolla pinnata 800 ppm nutrition. The results of this study concluded that 800 ppm azolla pinnata, 800 ppm banana peel and 800 ppm combination of azolla pinnata and banana peel in the growth of ground spinach plants (Ipomoea reptans Poir.) Were effective to increase harvest weight and increase chlorophyll content of land spinach (Ipomoea reptans Poir.) Namely chlorophyll a, chlorophyll b and total chlorophyll of land spinach plants (Ipomoea reptans Poir.).
