Tomato is an important vegetable crop and has been widely cultivated as a garden plant or commercially. The purpose of this study was to measure the effectiveness of organic fertilizer based on coal and cow dung based on several tomato varieties. This study used a factorial randomized design with two factors, namely the type of fertilizer consisting of "Saputra" coal fertilizer (BB), "Bio Alam Asri" manure (BA) and without organic fertilizer (B0); and the other factor is the tomato variety factor (V), namely Servo F1 (VS), Gustavi F1(VG), and Fortuna 23 (VF). Based on the results of the study, it was found that the treatment of BB and BA, in general, had a significant effect on vegetative growth and generative yields including fruit quality in the three tomato varieties tested. The highest number and fresh weight of tomatoes per plant were obtained in the treatment of BB, namely 44.00 fruits and 3.00 kg, higher than BA fertilizer, namely 39.11 fruit and 2.62 kg, and B0 namely 34.00 pieces and 2.20 kg. The highest number and fresh weight of tomatoes per plant were obtained in VS varieties, namely, 42.33 fruits and 2.74 kg, followed by VG varieties at 40.11 fruits and 2.71 kg and the lowest was VF at 34.67 fruit and 2.38 kg. The highest vitamin C content of fresh fruit was obtained in the BB treatment, which was an average of 36.75 mg/100g, higher than the treatment with BA fertilizer and B0, which were 32.81 mg/100g and 31.07mg/100g.

The pumelo population in Bali is declining one is caused of a lack of good-quality seeds. This research was conducted to determine the effectiveness of organic coal fertilizer and rabbit farm waste as organic fertilizers for the growth of pomelo grafting seedlings. The research design used a nested pattern randomized block design with 3 replications. There are two factors, the first factor is the type of fertilizer, which are Coal fertilizers, Rabbit Farm Waste fertilizers, and Cow Manure fertilizers. The second factor is the dose of each type of fertilizer which consists of 3 levels, namely: 10 tons/ha; 20 tons/ha; and 30 tons/ha. The results showed that the effectiveness of the treatment of the type of organic fertilizer and the dose of the type of organic fertilizer had no significant effect on all observed variables. This shows that both coal fertilizer and rabbit manure have almost the same quality as cow manure in influencing the growth of pomelo seedlings. The effectiveness of fertilizers tested on the average shoot length of grafting tends to show the highest yields obtained at the highest dose (30 tons/ha), namely Coal fertilizer which is 28.80 cm, rabbit manure is 31.87 cm, and cow manure obtained is 28.13 cm.

Cabbage plants (Brassica oleracea) belong to the Brassicaceae family, is a vegetable that is widely cultivated by farmers in rural Indonesia. In an effort to increase the productivity of purple cabbage it is necessary to carry out soil management. Andisol is one type of soil that is relatively fertile but has a high level of P absorption so it is necessary to add Chicken Manure and TSP Fertilizer. The purpose of this study is to determine the effect of treatment and response from the combination of treatment on the application of chicken manure and TSP fertilizer on the growth and production of purple cabbage plants. The research design used was a group randomized design (RAK) with 2 factors arranged factorially. The first factor is chicken manure fertilizer which consists of 3 levels, namely: K1 = chicken manure fertilizer 10 tons / ha (50 grams / polybag), K2 = chicken manure fertilizer 20 tons / ha ( 100 grams / polybag) and, K3 = chicken manure fertilizer 30 tons / ha ( 150 grams / polybag). The second factor of TSP fertilizer consists of 3 levels, namely: T1 = TSP 200 kg / ha ( 1 gram / polybag), T2 = TSP 300 kg / ha ( 1.5 grams / polybag) and, T3 = TSP 400 kg / ha ( 2 grams / polybag). Treatment of Chicken Manure (K), TSP fertilizer, and Interaction (KxT) had no real effect (P ≥0.05) on the variables of maximum plant height, maxmium leaf count, root length, flower crop diameter and wet weight of crop per plant.

Among various flower varieties, chrysanthemum (Chrysanthemum sp.) is one of the most significant decorative flower commodities. Along with Aphis sp., which may do a great deal of harm, Thrips sp. pests pose a serious risk to chrysanthemums. Use of organic, non-toxic materials, such as plant-based biopesticides, is one substitute for managing Thrips sp. The purpose of this study is to ascertain which weed extract solutions, and at what doses, are most efficient at managing aphid pests on chrysanthemum plants. Two factors were included in the research design, which used a Factorial Randomized Block Design in a greenhouse setting: the type of weed extract solution and its concentration. Analysis of Variance (ANOVA) was used to examine the production data; at a 5% significant level, a Duncan or LSD test was then performed. The quality of the chrysanthemums was then compared to the Indonesian National Standard (SNI) 01-4478-1988. Aphid population, aphid mortality, flower diameter at full bloom, and percentage of flower damage (derived by dividing the number of damaged petals by the total number of observed petals) were among the observed variables. The findings showed that the chrysanthemums grown in the Ageratum conyzoides weed extract solution had the maximum growth and flower production, along with the lowest percentage of diseased leaves. Furthermore, the 300 grams/liter concentration demonstrated greater efficacy in impeding pest attacks, resulting in increased chrysanthemum development and a reduced proportion of leaf infection. For chrysanthemums to develop as best they can, the study advises applying a solution of Ageratum conyzoides weed extract at a dosage of 300 grams/liter.

The market value of horticultural products, particularly ornamental plants, is quite high. It is necessary to conduct research on the introduction of appropriate technology for increasing the intensity of chrysanthemum cultivation, such as the use of chrysanthemum leaf messenger and a combination of manure, which is formulated with local resources in chrysanthemum flowers to improve quality and add value and utilize the potential of agricultural resources that are easy to apply based on the capacity of farmers and have a real impact on increasing income. This study's objective was to determine the optimal concentration of chrysanthemum leaves and the optimal combination of manure for enhancing the production and quality of chrysanthemums. Using a Factorial Randomized Block Design, field research is conducted in a greenhouse using two factors: the dosage of defoliated chrysanthemum leaves and a mixture of manure. The obtained data were statistically analyzed using the ANOVA test. If the effect of a single treatment is genuine or very real, the average value test is continued. Least significant difference (LSD) is 5%, whereas Duncan's 5% indicates an interaction between the two factors tested. The treatment of defoliated leaves had a real to very real effect on all variables, with the exception of stem diameter, whereas the combination treatment of organic fertilizers had a real to very real effect on all variables. The interaction between the quantity of defoliated leaves and the combination of organic fertilizer has no significant effect on all variables. The administration of a dose of 5 tons/ha and the combined use of goat manure and pig manure increased the length of the flower stalk, the weight of the flower stalk, the diameter of the stem, the diameter of the flower, the fresh weight of the most cost-effective flowers, and the proportion of leaves infected with rust. According to SNI 01-4478-88, the chrysanthemums produced in this investigation are of quality class A.
