Indonesia is a tropical country that has abundant natural wealth in the form of flora and fauna. One of the fauna that is beneficial to humans is the honey bee. An influential factor in the success of honey bee cultivation is the availability of bee feed in the form of flowering plants. The flowers of these plants contain nectar, pollen, or nectar and pollen which is very influential in honey production. The availability of a 500 m wide yard at the Nurul Islam Sekarbela Islamic Boarding School, Mataram City, is currently only used as a living pharmacy planted with medicinal plants and ornamental plants, such as several types of flowers and there are several large trees such as mango trees as shade trees. Almost all types of flowering plants are a source of bee food, because flowers are pollen producers. This study uses an exploratory method with purposive sampling technique. After determining the sampling point, then the process of identifying what plants were found in the Nurul Islam Islamic Boarding School Area was carried out. This identification uses the key to the determination of resin and pollen-producing plants, and is based on related scientific journals. The results of the research that have been carried out obtained 16 types of resin-producing plants, namely: four o'clock flowers, red shoots, sunflowers, turi, purslane, palm, kastuba, miana, longan, mango, rambutan, lime, banana, guava, avocado, and jackfruit. So it can be concluded that the grounds of the Nurul Islam Islamic Boarding School can be used as a beekeeping by placing bee stubs in tall trees, away from disturbances from students or the surrounding community.

Eggplant (Solanum melongena L.) is a garden plant grown for its fruit. Some green eggplant farmers in West Lombok, use NPK fertilizer as the main choice to produce quality fruit, they never use organic fertilizer when planting green eggplant for fear that the size of the fruit produced is not as big as the fruit grown using NPK. Low quality green eggplants are rarely in demand by the public, so it will have an impact on decreasing selling prices in the market. This study aims to determine the effect of fertilizer variation on the growth of green eggplant (Solanum melongena L). This research is a true experiment that wants to see the growth of green eggplant plants given a variety of fertilizers. In this study using 3 treatments, namely PA (chicken manure + soil in a ratio of 2:1), PK (goat manure + soil in a ratio of 2:1), PN (NPK fertilizer 20 g given to each polybag size 2 kg). The results of the analysis from the table and the average diagram, the application of fertilizer variations showed that there were differences in the growth of green eggplant plants on the parameters of plant height, number of leaves, number of branches, number of flowers and number of fruit. The results of the ANOVA statistical test showed that there was an effect of fertilizer variation on the parameters of the number of leaves and the number of branches, but it was not significant on the parameters of plant height, number of flowers and number of green eggplant (Solanum melongena L.).
