Factorial experimental designs involve more than one factor and what needs to be tested is the interaction between treatment factors in addition to the effects of each treatment factor itself. This study aims (a) to consider graphical line drawings as a reference for formulating conclusions that there is an interaction between the two treatment factors, and (b) to examine and follow up on the results of the analysis of variance in factorial experiments which conclude that the interaction between the two factors is significant, not to ignore the possibility of single factor variance dominating. . The research refers to the research data "Study of the Effect of Pellet organic Fertilizer from Municipal Waste on the Nutrient Content of Spinach (Amaranthus hybridus L)." the two single factors are significant, the graphic lines intersect a lot, the data presentation and interpretation refer to the combined treatment (b) the carotene content data in spinach vegetables, the interaction of the two treatment factors is significant, the two single factors are significant, the graphic lines are almost all parallel and almost intersect, so the data presentation and the interpretation of the PeOF raw material type factor refers to a single factor, (c) the data on the content of vitamin C in spinach vegetables, the interaction of the two treatment factors is significant, the two single factors are significant, the graphic lines are almost all not parallel, almost intersect, so the data presentation and the interpretation of the material type factor PeOF standard and urea application factor refer to a single factor. When using a factorial design, it is found that real interactions do not necessarily mean that the data presentation refers to the combined treatment. It is necessary to test further for the possibility that the diversity of single factors is more dominant so that the data presentation and conclusions refer to a single factor.

Eggplant is a horticultural crop that contains vitamins and nutrients such as vitamin A, vitamin C, potassium, phosphorus, iron, protein and carbohydrates. Optimizing eggplant productivity can be supported by the application of mycorrhizal fertilizers as a provider of phosphorus elements and maintaining soil moisture. The aim of this study was to distinguish the timing of mycorrhizal fertilizer application in supporting eggplant productivity. The treatment was divided into three, namely P1: fertilizing two weeks before planting at a dose of 5 kg/ha; P2: fertilizing one week before planting at a dose of 5 kg/ha; and P3: fertilization at planting time of 5 kg/ha. Completely randomized design with 3 replications was tested in this study. The results of the study were that mycorrhizal fertilizers on vegetative observations tended to be better on the treatment at planting time compared to the other two treatments, but on vegetative observations at plant height at the age of 21 DAT the treatment 1 week before planting turned out to be superior to the other two treatments. Generative observations tended to have better results in the treatment 1 week before planting than the treatment at planting time which tended to have lower yields where the fresh weight of the fruit only weighed 150,35 grams while the treatment 2 weeks before planting had a fresh weight of 161,35 grams . The length of the treated fruit 1 week before planting was 27,35 cm far above the treatment at planting with a length of only 24,26 cm.

Egg shells are household waste that is very easy to find. Egg shells or egg shells can also come from waste disposal of laying hens. So far, there is a lot of egg shell waste by martabak sellers in Surabaya. The lack of public knowledge and insight regarding the use of eggshell waste causes this waste to pollute the environment. This study aims to determine the interaction between the application of organic fertilizer eggshell waste pellets and the dose of urea fertilizer used and its effect on the growth and yield of spinach plants. This research was conducted from mey to june 2022 at the Experimental Garden of the Faculty of Agriculture, Wijaya Kusuma University, Surabaya. This experiment was carried out using a randomized block design consisting of two treatment factors, namely POPe of eggshell waste (P) and dose of urea (K). This treatment was repeated three times with P0 (without POPe treatment), POPe treatment of eggshell waste consisting of P1 (9 gr POPe), P2 (18 gr POPe), P3 (27 gr POPe) and K0 (without urea dose), dose urea K1 fertilization (3.2 gr urea). The results showed that the use of POPe and urea on spinach plants had no significant effect on any observed parameters.

Hydroponics is a plant cultivation technique that uses water as a growing medium. The acidity level (pH) of water is an important factor in the success of hydroponic plant cultivation. High water acidity (pH>8) can be controlled by adding acid solution to a pH level of 5.8-7.0. This research was conducted to examine the nutrient content of lettuce. The research used a Randomized Block Design with 9 treatments (3 types of water and 3 types of acid solution). The types of water used include Kebonsari well water, Bugul Kidul well water and Pasuruan city PDAM water. The acid solutions used include nitric acid, phosphoric acid and sulfuric acid. The results of the research show that adding acid solutions to all types of water produces different plant nutrient contents. The addition of nitric acid and phosphoric acid solutions respectively had a significant effect on the N and P nutrient content of lettuce plants. The addition of phosphate solution can be recommended as a pH lowering solution in hydroponic cultivation.
