One of the most important procedures in denture fabrication and orthodontic treatment is molding the patient’s detail oral cavity to determine the treatment planning. This procedure was done by using alginate impression material or irreversible hydrocolloid in which the basic material is sodium alginate imported from abroad because it is extracted from brown algae which its habitat is not in Indonesia so that it is causes the impression material is relatively expensive roomates is impact to high cost of dental treatment. Indonesia as the archipelago country has availability of abundant brown algae Padina sp. Especially in Puntondo-Punaga seashore, South Sulawesi, but it has not Cultivate yet by the local society because it is never discovered by alginate industry so it is just grow wild and its potency is useless. This experiment identified the purposes of how much sodium alginate is produced from Padina Sp. Extraction as the basic matter of irreversible hydrocolloid. The design of this study is experimental design with one shot case study method. In early stage research, extraction of alginate in the form of sodium alginate. After that, they are weighted by using analytical weight in milligrams (mg) unit. Then, it is compare with the standard sodium alginate to observe the similarity of molecules by using FTIR (Fourier Transform Infra Red) device. Data were Analyzed using mean differences. Based on Padina extracted, produced 12.86 g of sodium alginate content or 28.4% from the cleaning algae was used roomates total weight is 45 g. Based on FTIR test, showed that sodium alginate is extracted similar to the standard sodium alginate with the found of hydroxyl, carboxylic acid, ether group and the which is the composer of sodium alginate. In conclusion, from both of infra red spectrum pattern, it was observed unsignificant difference. Extracted sodium alginate Padina is same with the standard sodium alginate and it has 12.86 g content.

Objective: This research aims to explore the potential of brown algae species padina sp. as a dental impression material by examining the physical characteristics of the sodium alginate extraction of brown algae species padina sp. Material and Methods:This research is a quasi-experimental with one-shot case study design. Samples are brown algae species padina sp. from Punaga and Puntondo beach in South Sulawesi. Brown algae species padina sp. is extracted to obtain sodium alginate and further tested for physical characteristics including viscosity test and water content. Results:The extraction of brown algae species padina sp. resulted in 250 grams (25%) of brown powdered sodium alginate that smelled fishy. Physical characteristic tests revealed the water content of sodium alginate species from brown algae padina sp. was 8%. This result is acceptable for sodium alginate water content as set by the Food Chemical Codex that requires less than 15% water content. The measurement of the viscosity obtained is 13.33 cps. Conclusion:These results indicate that the species of brown algae padina sp. has the potential to be one of the basic materials of dental impression material.

Obat kumur telah dipakai secara luas pada masyarakat. Fungsi utama dari obat kumur adalah membersihkan rongga mulut, mengurangi napas tidak sedap, mempunyai berbagai macam rasa dan membuat mulut terasa segar. Penelitian ini bertujuan mengetahui daya hambat anti bakteri beberapa jenis obat kumur terhadap Streptococcus mutans. Jenis penelitian ini adalah eksperimen laboratoris rancangan quasi experimental. Sampel adalah obat kumur dengan kandungan iodine povidin, hexatidine, alcohol, benzydamin HCl dan aquadest sebagai kontrol. Isolat S.mutans segar adalah bakteri S.mutans yang telah diremajakan. Kemampuan daya hambat sampel obat kumur dapat terlihat dengan adanya zona inhibisi berupa daerah jernih (zona bening) yang terbentuk setelah masa inkubasi selama 24 jam di dalam inkubator dengan suhu 37 o C. Zona bening diukur dengan menggunakan kaliper secara vertikal, horisontal dan diagonal kemudian dirata-ratakan. Hasil penelitian menunjukkan kemampuan daya hambat terhadap pertumbuhan S.mutans yang terbesar adalah obat kumur yang mengandung hexatidine dan benzydamin HCL.
