Population growth that increases exponentially becomes a challenge in itself in meeting food security, while food production increases at a slower rate than population growth. In meeting this food security, one solution is to create local food security on a household scale with the urban farming method. This is because 56% of the world's population lives in urban areas. There is a classic American planting pattern developed by the Haudenosaunee, namely three sisters planting or Dioheka. Dioheka is an organic polyculture cropping pattern that uses corn, pumpkin, and chickpeas as its main components. One of the factors that become an important component in fruit production is pollination, either by insects, wind, or water. Insects that have potential as pollinators are Trigona laeviceps, which are stingless insects or commonly called klenceng. The duration of the bee perching on the flower or flower handling time is a parameter that needs to be considered because the longer the bee perches, the higher the amount of nectar in the flower and the greater the chance for the flower to become fruit. The purpose of this study was to determine the best growing space for Dioheka and its effect on flower handling time by klenceng. The study was conducted using a completely randomized design in the form of 6 growth chamber treatments and 6 replications. Treatment is in the form of planting in growbags measuring 75 L, 100 L, and 200 L which are placed in a greenhouse together with klenceng colonies. The results showed that the highest klenceng arrivals were found in corn plants at 200 L growbags, which was 1327.2 seconds per day and in pumpkins at 100 L growbags, which was 571.8 seconds per day, while the bean plants were not visited by klenceng. In maize and beans, the fruit with the highest yield was fruit grown in a 200 L growbag, while pumpkins did not produce fruit.
