Pollen is used by bees as a source of protein to support life and increase bee productivity. The sizes and types of pollen carried by bees vary greatly. Plants originating from the highlands are likely to produce pollen diameters that are different from those from the lowlands. It is necessary to measure the diameter of pollen that honey bees feed from different plant types to find out the food source that bees prefer. This research aims to determine the effect of height on the diameter of pollen from various types of plants carried by honey bees to increase production. The research method used in this research is field experimental. The research design used a completely randomized design (CRD) linear model with 3 altitude treatments, namely height 0-100 masl (P1), height 400-499 masl (P2) and height 800-899 masl (P3). The research results show that altitude has a very real influence (P<0.05) on bee pollen diameter. The largest average pollen diameter located at P2, namely 53,260c ± 5,703 μm for pollen width (Equatorial) and 58,144c ± 5,894 μm for pollen length (Polar). Then the average of the second diameter at height P3, namely 47.825b ± 5.426 μm for pollen length (Polar) and 51.435b ± 5.867 μm for pollen width (Equatorial). Apart from that, the smallest average pollen diameter is located at P1 with pollen width (equatorial) of 32.258a ± 2.544 μm and pollen length (pollen) of 38.157a ± 3.752 μm. To meet pollen needs, bees do not depend on diameter certain things specifically. The largest pollen that a bee can swallow is pollen in diameter equatorial pollen between 9.63 μm to 94.79 μm.
