Abstract

Agam district has a coconut plantation of 56,744 hectares with an average production of 3,000 tons per year. Coconut water is one of the coconut plant products that has not been utilized optimally. Many benefits or new products that have a higher selling value use coconut water as a raw material. One of the products derived from coconut water that we consume daily is Nata de coco. Nata de coco has high fiber, but low in calories. Nata de coco can also be a business opportunity for the home industry. Based on the business opportunity from Nata de coco, The community service of Politeknik ATI Padang held the training of the production of Nata de coco to the women community in Kamang Hilir Village, Agam District, West Sumatera. The training was carried out on February 5, 2023 attended by 30 participants. The training began with the explanation about the materials and tools used in making Nata de coco. The main materials used were coconut water, urea, sugar, Acetobacter xylinum. Then, the practice is carried out jointly between the women community and the community service team from Politeknik ATI Padang. The training was closed with the presentation of business prospective from Nata de coco. All of the participants were enthusiastic with this training. It is expected that the women community in Kamang Hilir Village have the knowledge and the skill to make their own Nata de coco.

Abstract

Nagari Sikucua, Kampung Dalam Subdistrict, Padang Pariaman produces nearly 800 tons of fragrant areca nut every year which is sent to Jambi to meet export needs. Areca nut contains tannins, substances that have many benefits, some of which are anti-inflammatory, corrosion inhibitors, antioxidants. This study aims to obtain tannins in areca nut extract through a kinetic maceration process with pre-treatment with ultrasonic irradiation wave. The dried areca nut was ground and sieved with various sizes of 20, 40 and 70 mesh and then extracted with ethanol as solvent. The concentration of ethanol used consisted of 35%, 50%, 65% and 80%. Ultrasonic irradiation waves were given for the initial 15 minutes of maceration and then continued with kinetic maceration for up to 4 hours in a water bath at 45°C. The extraction results were concentrated in a rotary evaporator and then tested for tannin levels using Follin Denish reagent in the standard series of tannic acid as a comparison with spectrophotometer UV-Vis. The highest yield of tannin content 11.10% was obtained in the 4-hour maceration process with pre-treatment ultrasonic irradiation at concentration of 80% ethanol with a size of 40 mesh.
