IMPROVEMENT ON WASTE SEGREGATION BEHAVIOR BY VERBAL AND VISUAL PROMPT IN INDONESIA INTERNATIONAL INSTITUTE FOR LIFE SCIENCES (i3L)
orting waste is seen to be an efficient way to promote recycling and lessen environmental
damage. To reinforce the waste sorting behavior, this study observed the impact of verbal and visual
prompts intervention in a community of a higher education institution, Indonesia International
Institute for Life Sciences (i3L). The treatment incorporated volunteers to stand guard beside the
canteen waste bins (visual prompt) to instruct every wrong waste separator to remove their waste
from the wrong bin to the correct bin (verbal prompt). The intervention was done for four weeks,
one hour every weekday from twelve to one p.m. The data collection was done in two ways: via
waste observation log during the four weeks of intervention and one precursor week of no
intervention; and through questionnaires distributed on the last week of the intervention. The
prompt generated a statistical improvement in the community’s waste sorting behavior, however,
due to flawed study design, the result and cause cannot be justified.
