Analysis of Input Optimization for Cassava (Manihot esculenta) Production in the Marga Tiga Sub-District East Lampung District

This study aims to ascertain how production inputs affect cassava farming and examine use as efficiently possible. The research location was selected because the area is a center for production. Cobb-Douglas function model an analytical technique used assess output. Analyze level of input utilization optimization at same time by comparing marginal product's value other inputs. study's variables included land area, labor, seeds, urea-fertilizer, NPK-fertilizer, ZA-fertilizer, SP36-fertilizer, herbicides, yields. result this that simultaneously influence Several in Marga Tiga District are still not optimal need be added, including organic fertilizer, urea ZA fertilizer. Meanwhile, several inputs, namely NPK SP 36 optimal, so farmers reduce them.
