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.

Aromatic areca catechu is one of the main agro commodities in West Sumatra. It contains tannin which are valuable compounds that are widely used in the textile industries, leather product manufacturing, or furniture industries. Utilization of tannin extraction from the aromatic betel nut is expected to increase its economic value. This study aims to extract tannin through kinetic maceration methods by varying the maceration duration of 1,2,3,4, and 5 hours; and varying the solvent concentration of ethanol 35%, 50%, 65%, 80%, and 96%. The scented areca nut powder used has a mesh size of e” 20, the stirring speed 450 rpm and the temperature kept constant at 45 oC. The extraction results were then concentrated and tested by UV-Vis spectrophotometric analysis with a standard solution of tannic acid. Optimal yield value is 3.750%  identified at maceration length of 2 hours with a solvent concentration of 65% ethanol.

Areca nut from Padang Pariaman as an export commodity is rich in tannin content and its ability as an antioxidant is used as the object of this research. The extraction of fragrant betel nut seeds has been carried out using the usual kinetic maceration method and the kinetic maceration method with ultrasonic wave irradiation pretreatment. The purpose of this study was to study the effect of ultrasonic irradiation on the tannin content, total phenol and antioxidant inhibition of the ethanol extract of areca nut seeds. A total of 20 grams of areca nut powder in a mesh variation of 20, 40 and 70 was extracted in 200 ml of ethanol with a solvent variation of 65% and 80%. Using three treatments, namely maceration treatment without ultrasonic irradiation, maceration with 15 minutes of ultrasonic irradiation pretreatment and the third treatment with 30 minutes of ultrasonic irradiation. The solvent was evaporated in a rotary evaporator and then tested for tannin levels using Follin Denish and DPPH reagents to measure antioxidants. The results of the highest tannin content were obtained in the third treatment, namely maceration with ultrasonic irradiation treatment 30 minutes, areca nut powder size 40 mesh, ethanol solvent 80% obtained tannin content of 12.5%. Meanwhile, the highest antioxidant activity was obtained at 70 mesh size, 80% ethanol solvent and the same treatment, which was 81.78.

The agricultural sector is one of the main pillars of the economy in Koto Tangah District. Increasing agricultural production requires the support of fertilizer availability in terms of quantity and price. In order to provide fertilizer at competitive prices, fertilizers are needed at low prices and are environmentally friendly. This community service activity is given to the community in Lubuk Minturun Village in the form of training in the manufacture of liquid organic fertilizer (POC) with a fermentation process and extracts of lemongrass. The main ingredient of this fertilizer is rice waste which can be easily collected by local people. The training covers the process of making fertilizer, the fermentation process to packaging. Lemongrass extract is added to increase nutrients in the soil and reduce odors from the fermentation process. The proposing team took this theme in order to provide an alternative for making POCs to the community in Lubuk Minturun Village in the hope of contributing to local flower or fruit plant nurseries. In this case, the proposing team took Lubuk Minturun Village as a model because this area is located close to the ATI Padang Polytechnic Campus, so that it can help the lives of the people around the campus.

West Sumatra has a high potential of coconut resources with most of it being processed for copra products. The pandemic situation in recent years has caused the price of copra products to fluctuate, so an alternative coconut processing is needed. Virgin Coconut Oil (VCO) is an alternative coconut product that can increase economic value of coconut and is needed as a supplement that can strengthen the body's immune system during the Covid-19 pandemic. One of the efforts to train the community to be able to process coconut into VCO is to conduct training activities that are directly located in the coconut farmer cluster, which is carried out in Sungai Sirah Village, South Coast District, West Sumatra. This community service activity aims to increase the competence of farmers in the village so that they can process the coconut produced into VCO, hence help their economy when the price of copra drops. The stages of the activity start from socialization, presentation on production process, and continued with demonstrating how to make VCO. Participants were divided into several small groups where they could immediately practice how to make this VCO with the correct fermentation steps. After the manufacturing process is well understood, the next step was training of how to do packaging and marketing. Farmers were trained on how to package products in order to get good quality product and then trained to sell VCO through online shop such as Facebook, Instagram, Tokopedia, etc. This activity helps add more insight in terms of processing and marketing, in which participants increase their knowledge and competence to form the basis for entrepreneurship of coconut processed products.
