Breadfruit is very good as a food substitute and can be used as solar carbohydrates to support prospective food consumption. Duwet Village, Wonosari Subdistrict, Klaten Regency has the potential for breadfruit trees in residents' yards. However, the breadfruit produced has not been used optimally because there is still a lack of knowledge and understanding of the use of breadfruit. The purpose of this community service was to provide knowledge and skills to members of Family Empowerment and Welfare (in Indonesian is PKK) in the village. The method implemented was counseling and training. Counseling and training are carried out virtually because it was still in a state of the Covid-19 Pandemic and the implementation of Restrictions on the Movement of Community Activities (PPKM). Counseling and training begins with the preparation of video tutorials for Making Breadfruit Flour and Video Tutorials for Making Processed Breadfruit Flour. The video is uploaded to the participants' WhatsApp Group (WAG). Before and before uploading the video, the participants were given a pre-test and post-test. The results of community service activities showed that there was an increase in participants' understanding in making breadfruit flour (29.22%), and making processed breadfruit (25.18%). Increased understanding of participants has exceeded the target to be achieved. Even though using social media, the dedication was successful.

Herbal teas come from other than tea plant (Camelia sinensis). Among the plants that can be used to make tea are ketapang leaves. Efforts are needed to combine with other leaves to make the product more acceptable to consumers. The study aimed to determine the chemical and organoleptic properties of ketapang herbal leaf tea varied by adding mint leaf powder. The stages of the research included making ketapang leaf powder, mixing the ingredients according to the treatment, and testing the tea powder. Tests consist of testing chemical properties (moisture content, ash content, total phenolic, and antioxidant activity) and organoleptic properties (color, taste, and aroma). A completely randomized design (CRD) unidirectional pattern was used in this experiment. The treatment variable was the addition of mint leaf powder with a concentration of 0%, 1%, 2%, 3%, 4%. Analysis of Variance (ANOVA) with a significance level of 0.05 was used to analyze the data obtained. Further tests with the Duncan Multi Range Test (DMRT) were carried out if significant differences were found. The results showed that the water content of ketapang leaf herbal tea powder combined with mint leaf powder was not significantly affected by variations in the added mint leaf powder. However, the ash content had a significant effect. Adding mint leaf powder also significantly affected the antioxidant activity, total phenolics, and organoleptic properties (color, taste, and aroma) of steeping ketapang leaf herbal tea. The total phenolic content and antioxidant activity decreased with the addition of mint leaf powder. The higher the concentration of mint leaf powder added to the ketapang leaf powder, the lower the antioxidant activity. However, adding mint leaf powder up to 4% could increase panelist acceptance of the taste and aroma of ketapang herbal leaf tea.

Public awareness of the food quality which is they consume is increasing. Food consumption becomes more varied by not only consuming carbohydrates, protein and fat sources, but balanced with the consumption of fruits as a source of vitamins. One way to maintain the quality of fruits during storage is to use edible coatings. Edible coatings made from hydrocolloid materials such as starch as natural coating materials, are non-toxic and safe for health so that starch-based edible coatings are feasible to be developed. One of them is arrowroot starch. Improving the coating function is done by adding antimicrobial ingredients, one of which is lemongrass extract. The purpose of this study was to determine the effectiveness of the use of antimicrobial edible coating on the physica and chemical characteristics of strawberryes during storage. The experimental design used in this study was a factorial completely randomized design, with the treatment of Antimicrobial Concentration (A) with five levels of treatment, namely: A1 = 0%, A2 = 0.1%, A3 = 0.2%; A4 = 0.3% and A5 = 0.4% and Storage Time, namely B1 = 0 days; B2 = 2 days; B3 = 4 days and B4 = 6 days. Each treatment was repeated twice to obtain an experimental unit of 5 x 4 x 2 = 40 experimental units. Product analysis carried out was weight loss, texture and total dissolved solids. Based on the data obtained, the use of antimicrobial concentration and storage time affect the results of the analysis. The longer the storage, the weight loss increased, the texture became softer and the total dissolved solids decreased.Keywords: antimicrobia, arrowroot, edible coating, lemongrass, strawberry
