Selection of maize lines for drought stress is the initial step in developing maize varieties with high production characteristics and resistance to drought stress. The research aims to determine the characteristics of maize lines in the vegetative phase and to select for resistance of maize lines in the vegetative phase using PEG 6000. The research used a Randomized Complete Block Design (RCBD), which was arranged factorially with three replications and two treatments. The number of treatments in this study was 40 treatment combinations, so there were 120 experimental units. Factor I was genotype, and factor II was the giving of PEG-6000 solution. All maize lines were planted in polybags measuring 20 x 20 cm. There are two levels of PEG 6000 solution treatment: 0% concentration (optimum condition) and 10% concentration, which is equivalent to -0.19 Mpa (drought stress condition) (Mexal et al., 1975). When the plants are 10 days after planting (DAP), drought stress is applied using a 10% concentration of PEG 6000 solution. The observed characters were plant height, root length, leaf area, leaf chlorophyll, plant wet weight, and plant dry weight. The research results showed that drought stress treatment mostly reduced the character values of plant height, root length, leaf area, leaf chlorophyll, plant wet weight, and plant dry weight. All tested lines showed significant differences in all tested characters against optimum condition treatments and drought stress. The lines resistant to drought stress were G4, G9, G11, G13, G14, G15, G16, G17, and G19.

One way to increase maize productivity in dry land is to develop superior maize varieties with high production, early maturity, and resistance to drought stress. The study aims to evaluate the characteristics of 10 hybrid maize candidates with high production, early maturity and resistance to drought stress. The research used a Randomized Complete Block Design (RCBD) with 13 genotypes (10 hybrid maize candidates, three comparison varieties (Jakaring, Pioneer-X, and Bisi-X)) as treatments. It was repeated three times, so that there were 39 experimental units. Drought stress using the CYMMYT method, namely drought stress, is carried out when the plants are 50 DAP until harvest, but providing irrigation with field capacity at 0 to 40 DAP with an interval of every 10 days. The observation parameters in this study were plant height, number of leaves, leaf length, leaf area, ear height, days of 50% tasseling, days to 50% silking, harvest age, number of kernel rows, weight of cob with husk, ear length, ear diameter, kernel width, kernel length, kernel thickness, kernel diameter, 1000-kernel weight, and production per hectare. The results of the study showed that the thirteen tested characters showed a very significant effect of the treatment, namely plant height, number of leaves, leaf length, leaf area, ear height, days of 50% tasseling, days to 50% silking, harvest age, number of kernel rows, weight of cob with husk, ear length, kernel width, and 1000-kernel weight. Four characters showed a significant effect of treatment: kernel length, kernel thickness, kernel diameter, and production per hectare. The ear diameter character did not show any significant differences between treatments. The broad heritability values for all tested characters for the 13 genotypes ranged from 49.90 to 97.90. Production per hectare was positively correlated with ear length (0.79**), ear diameter (0.37*), and kernel thickness (0.59**). Furthermore, the production character per hectare is negatively correlated with harvest age (-0.49**) and kernel length (-0.38*). G1, G2, G3, and G6 are the hybrid maize candidates selected for the release of hybrid varieties with high production and early maturity.

Farmer empowerment through the development of local agricultural commodities is an important strategy to increase farmers’ income and strengthen the independence of farmer groups. This community service activity aimed to enhance the capacity of the Padimas Farmer Group in Sana Tengah Village, Pasean Sub-district, Pamekasan Regency, through the development of local Madura melon as a regional flagship commodity. The program was implemented using a participatory–collaborative approach that actively involved farmers in all stages of the activity, including the identification of local needs and potentials, provision of demonstration plot land, cultivation assistance, and continuous monitoring and evaluation. The melon demonstration plot served as a practical learning medium for farmers in applying cultivation techniques adapted to local agroclimatic conditions. The results showed that the development of the local melon demonstration plot significantly improved farmers’ knowledge and skills in melon cultivation, with a plant survival rate reaching 99%. In addition, this activity supported the establishment of a group-based flagship commodity with promising economic value and market opportunities. Overall, the farmer empowerment program contributed positively to strengthening farmers’ economic independence and has the potential to serve as a model for sustainable horticultural agribusiness development in the Pamekasan region.

Sugar apple (Annona squamosa L.) is one of the local fruit commodities with high potential as a source of functional natural ingredients. This study aims to identify the morphological characteristics and profile the phytochemical content of local Sumenep sugar apple fruit as a basis for the development of its bioactivity. Morphological observations were carried out in the Sumenep area, including fruit shape, size, stem circumference, leaf characteristics, and flower parts. Phytochemical analysis was conducted using qualitative tests for tannins and saponins, while tests for flavonoids and alkaloids are planned for the next stage. Observation results showed that local Sumenep sugar apple fruits have morphological variations in the form of ovoid, round, and oblong shapes, influenced by genetic factors and environmental conditions. Phytochemical tests showed the presence of tannins, indicated by a color change to dark green when using FeCl₃ reagent, as well as the presence of saponins, demonstrated by the formation of stable foam during the shaking test. These findings reinforce the potential of local Sumenep soursop fruit as a candidate source of functional natural compounds, particularly in relation to antioxidant, antimicrobial activities, and other pharmacological benefits. Further studies are needed to analyze other phytochemical contents and evaluate bioactive activities more comprehensively.
