Abstract:
Cabbage plants are among the highest needs in Indonesia. In various attempts by farmers
to increase chili production, the disease in chili plants often causes farmers to fail to
harvest. The use of pesticides in agriculture is quite important in preventing and reducing
disease in chili peppers. Pesticides for chili peppers are widely distributed on the market
and have the advantages of each product offered to farmers, so farmers must be more
careful and understanding in choosing pesticides to be used in preventing chili pepper
disease. The Bukittinggi City Agriculture and Food Service in improving food security
makes this one of the efforts in running the program by determining the best pesticide
selection in preventing chili plant disease so that it can improve the yield and quality of
the chili plant. The best pesticide selection is required. Criteria as conditions in the
selection of the best pesticides. The goal achieved in this study was the introduction of a
decision support system using the Weighted Aggregate Sum Product Assessment
(WASPAS) method to support decision-making to help farmers in providing alternatives
to assess the best pesticides preventing disease in chili plants. Methods used in research
include data processing, data analysis, system design, implementation and system testing.
Data processing is obtained from interviews and literature studies of 30 data. Then
analysis of the data is done, determining the attributes and criteria, determining the
decision matrix, normalizing the matrix, generating the pesticide alternative value,
normalizing, calculating the alternative value (Qi), lastly determining the ranking. The
results obtained are that the system is able to produce alternative pesticide optimization
values already ranked 3 highest to lowest with optimization values of Tridex 80 WP,
Holyzeb 80 WP, Lamzeb 80 WP.
