Zodia are included in medicinal plants because it contains secondary metabolites such as flavonoids, tannins, alkaloids, steroids/triterpenoids that have many benefit and also as mosquito repellents. The growth and content of secondary metabolites in plants can be affected by environmental factors such as water availability. Research on the cultivation of this crop is still limited. Environmental modification in cultivation is needed to increase its secondary metabolites, and the study of the potential of this plant as medicine are necessary. This study aimed to determine the effect of water availability on the growth and secondary metabolites of zodia. The research was carried out in July-November 2021 in Greenhouse, Faculty of Agriculture, Universitas Sebelas Maret, Surakarta. The method used was a completely randomized design, one treatment factor with 4 levels namely, 100, 80, 60 and 40% of field capacity. Each treatment was repeated 6 times so that there were 24 experimental polybags. The data analysis used is Analysis of Variance, and the Duncan’s Multiple Range Test at the 5% level. The results showed that the availability of water at a level of 60% field capacity gave the best average growth parameters (plant height and number of leaves) among other treatments. The flavonoid content in each treatment showed the same average. The results of the GCMS (Gas Cromatography and Mass Spectroscopy) test of zodia leaves showed that there were dominant bioactive compounds, namely ethylbenzene, octadecamethyl cyclononasiloxane, pentadecanoid acid and heptadecanoid acid. It is suspected that the content of these compounds has the potential as antifungal, antibacterial, antioxidant and anticancer.

Black rice generally has problems in cultivation such as relatively long plant life, high habitus and low productivity. Plant breeders use several methods in hybridization activities, such as backcross method that can lead to the development towards emphasizing the superiority of each parent. This research aimed to study and determined the success rate of the black rice lines F1 backcross and the parents’ performance. This research was conducted using F1 of promising lines, parental lines and the Jeliteng variety with 9 sets of crosses. Each line and variety were repeated 3 times, in total there were 57 experimental units. The observation parameters of this research were plant height, crossing success, weight of seeds, length and width of grain, flowering age, harvesting age also number of grains and unfilled spikelet. The results of this study showed that parents plant height was positively correlated with the number of productive tillers. The taller the plant, the more productive tillers and the more flowers can be crossed. The success of the cross can increase with the number of flowers crossed. The success of crosses between F1 black rice promising lines and their parents has a success rate range of 10.82% to 33.75%. The findings imply that F1 crossbreeding of black rice promising lines with their parents can be carried out to produce backcross offspring.

Chili consumption in Indonesia has increased. Efforts to increase chili production need fertilization through roots and leaf fertilization. The research aimed to obtain optimum intervals of NPK (nitrogen, phosphor, potassium) fertilization and kinds of foliar fertilizer for the growth and yield of chili. The research was conducted from April to August 2020 in Gayam Village, Sukoharjo Regency, Central Java, Indonesia. This study used an experiential method with a Randomized Complete Block Design (RCBD) of 2 factors. The first factor was an interval of NPK fertilization (16-16-16) with a concentration of 25 g.L-1 with a dose of 240 mL.plant-1. The interval of NPK fertilization consists of 4 levels, NPK fertilizer which was applied every 5, 10, 15, and 21 days. The second factor was foliar fertilizer which consists of A foliar fertilizer, B foliar fertilizer, and C foliar fertilizer. The results showed that the interval of NPK fertilizer affected the number of dichotomous branches, dry stove weight, cumulative fruit, cumulative fruit weight, and fruit length at 1st harvest. NPK fertilization every 15 days increased the dichotomous branches by 23.16%, dry stove weight by 37.98%, cumulative fruits by 37.41%, and cumulative fruit weight by 41.46%. B foliar fertilizer and A foliar fertilizer gave the same performance in dichotomous branches. There was no interaction effect between the interval of NPK fertilization and the kind of foliar fertilizer on all growth and yield variables. NPK fertilization optimum intervals as supplementary fertilizers should be given every 15 days. This research can be used as a reference for farmers in fertilizing chilies.

Extended use of synthetic chemical fertilizers may degrade soil quality. As a synthetic chemical fertilizer substitute, organic fertilizer can improve soil quality, produce healthier agricultural products, and be environmentally sustainable. Thus, coffee grounds liquid organic fertilizer may solve this problem. This study examines how liquid organic fertilizer made from coffee grounds affects land kale's physiological and growth characteristics. A fully randomized experimental design with one factor and 11 treatments was used. A control group, NPK-16-16-16 4 g, and Arabica, Robusta, and Liberica coffee were treated with three concentrations (4 mL.L-1, 12 mL.L-1, and 20 mL.L-1). Four replicates were run for each treatment. The investigation found that coffee ground liquid organic fertilizer does not meet Minister of Agriculture Decree 261/KPTS/SR.310/M/4/2019 criteria. Compared to the control group, liquid organic fertilizer made from coffee grounds did not increase land kale growth. Additionally, it did not grow as well as with NPK16-16-16 fertilizer. Coffee grinds liquid organic fertilizer only enhances kale growing on land, promoting sustainable agriculture.

Red ginger is one of the export commodities of spices in Indonesia which plays a significant role in the country's foreign exchange earnings. In order to meet market demand, ginger cultivation needs to be fertilized both organically and inorganically to increase production. ZA fertilizer for plants serves to stimulate vegetative growth. This study aims to determine the response of red ginger to the application of ZA fertilizer has a significant effect on the growth and yield of red ginger and to obtain the optimum dose of ZA fertilizer for the growth and yield of red ginger. This research was carried out in March - August 2021 until it was completed in Pelem Hamlet, Wonorejo Village, Jatiyoso District, Karanganyar Regency, Central Java Province with coordinates 7°43'24.7”S 111°05'31.2”E. The experimental design was a Completely Randomized Complete Block Design (RCBD). This study consisted of 4 treatments with 6 replications so that 24 experimental units were obtained, while the treatments in this study were as follows: P0: Control without ZA fertilizer, P1: Treatment 225 Kg ZA/ha or 22.5 g/m2, P2: Treatment 450 Kg ZA/ha or 45 g/m2, and P3: Treatment 675 Kg ZA/ha or 67.5 g/m2. The results showed that ZA fertilizer had no significant effect on the yield of red ginger, but on growth observations, P2 treatment with a dose of 450 Kg ZA/ha can have a significant effect on the increase in the number of plants per plot. The dry weight of the stover was strongly correlated with the weight of fresh rhizomes with correlation values (r) 0.508.
