Bintangur (Calophyllum soulattri Burm. F.) is a type of medicinal plant that has quite a lot of benefits such as antioxidant, anti-inflammatory and antibacterial, so it is important to develop it into a dosage form. Emulsions are preparations containing liquid medicinal ingredients or drug solutions dispersed in a liquid carrier. Emulsion preparations are preparations that are more easily absorbed when administered orally. Evaluation of the physical properties of the emulsion was carried out from organoleptic, pH, and viscosity parameters to produce good physical properties because they affect the resulting therapeutic effect. 150 mL of the preparation was made and evaluated for the physical properties of the organoleptic test, pH test, and viscosity test. The pH of the preparation must correspond to the pH of the oral preparation, namely 5-7, and the resulting viscosity must not be too runny or too thick because it is difficult to redisperse. The organoleptic test results of the bintangur extract emulsion had a characteristic yellow-brown color and the aroma of coconut oil with a bitter-sweet taste. The pH test results of the bintangur extract emulsion entered the range for oral preparations 5-7 with an average of 5.936 and the viscosity of the bintangur extract emulsion was 114.2 cP.

Riskesdas data in 2018 showed that the number of tooth decays in West Kalimantan province was 49.55% and that in Pontianak City was 39.52%. The results of a preliminary survey conducted on 5th-grade students of SDN 09 Pontianak found an average of three deciduous teeth and four adult teeth affected by dental caries. One way to prevent dental caries is to brush the teeth using toothpaste that contain active antibacterial ingredients. One herb widely used as an active ingredient in toothpaste is siwak. This community service activity aims to increase knowledge and skills in making herbal toothpaste to reduce the dental plaque index. This activity uses health counseling methods through lectures, leaflet distribution, and training on making herbal toothpaste from siwak. This activity was conducted in collaboration with SDN 09 Pontianak and was held on Friday, June 24, 2022, with 53 participants. From this activity, the participants received education on the benefits of herbal toothpaste for dental and oral health. In addition, this training activity can increase creativity and skills in creating herbal toothpaste and foster an entrepreneurial spirit. After this activity, it will continue with training activities with the theme of entrepreneurship as part of efforts to downstream and commercialize herbal toothpaste products.
