Antibacterial Effect of Chitosan from Squid Pens against Porphyromonas gingivalis
Objectives: To find the antibacterial effect of chitosan from squid pen against Porphyromonas gingivalis at certain concentration.
Methods: Suspension of chitosan 1.5% (w/v) was diluted in several tubes. The lowest concentration with no bacterial growth is considered to have antibacterial activity against Porphyromonas gingivalis.
Results: There was no bacterial growth in nutrient agar media at the concentration of 12.5%.
Conclusions: Chitosan that was made from squid pens has antibacterial activity against Porphyromonas gingivalis.

Result of Chitosan dilution on Porphyromonas gingivalis
Replication in this table explain that each of the chitosan dilution sample replicated 4 times.
| Concentration | Replication | Colony Forming Unit (mean) | Percentage |
| Positive Control | 4 | 149.5 | 100% |
| 25% Concentration | 4 | 0 | 0% |
| 12.5% Concentration | 4 | 0 | 0% |
| 6.25% Concentration | 4 | 10.75 | 7.19% |
| 3.13 Concentration | 4 | 24.00 | 16.5% |
