ONSPOT is a business owned by students of the Department of Agricultural Product Technology, Faculty of Agriculture, Riau University. This business is engaged in the contemporary beverage with the main ingredients of functional food yogurt and kefir. ONSPOT's business development received funding for activities through the University Student Entrepreneur Competition (KMP) activity in 2020 for the business development category. It is believed that this business prospect is quite promising in the future considering that ONSPOT products carry contemporary beverage products containing good bacteria that have an impact on health and have a good taste. However, the great potential that ONSPOT has to develop its products is not followed by an optimal marketing and branding process, where the marketing process is still carried out through communication from one person to another and through Instagram. The branding process is still constrained by minimal information. This causes the limitations of ONSPOT to be widely known by the public. Entrepreneurship development service activities by conducting training on ONSPOT website management and optimizing ONSPOT social media, so that ONSPOT appeals are increasingly recognized by the public

Fish crackers are one of processed poducts with the fish as the main ingredient with addition of flour orstarch. This purpose of this study was to get the best ratio between sago starch and motan fish. This researchused a Complete Randomized Design Experiment with five treatments and three replications. The treatmentswere were the ratio of sago starch : motan fish 90:10 (K1), 80:20 (K2), 70:30 (K3), 60:40 (K4), 50:50 (K5). Thedata obtained were statistically analyzed using Analysis of Variance (ANOVA) and Duncan’s New MultipleRange Test (DNMRT) at 5% level. The parameters observed were swelling power, moisture, ash, and proteincontents as well as sensory test. Ratio of sago starch and motan fish significantly affected moisture, ash andprotein contents, colour, taste, aroma, crispiness, and acceptance by panelist. The best treatment of crackersfrom this research was K4 which had swelling power 21.57%, moisture content 11.90%, ash 0.97%, andprotein 22.00%. The result of descriptive test assessment, crackers had no brown colour (2.42), flavor fishcrackers (3.70), taste fish (3.72), and texture crispiness (2.57). Overall assessment hedonic test of crackerswas preferred by the panelists.

This research was aimed to get the best crackers from a combination ratio of taro flour and red bean flour incrackers making. Research method was completely randomized design (CRD) experiment which consisted offive treatments and each treatment was repeated three times. Treatments of taro flour and red bean flour were90:10, 80:20, 70:30, 60:40, 50:50. Data were statistically analyzed by using analysis of variance and continuedwith duncan’s new multiple range test at 5% level. The result of this study showed that the ratio of taro flourand red bean flour significantly affected moisture contents, ash contents, protein contents, color, flavour,aroma, and crunchiness. Based on this research, the best treatment was the crackers with taro flour and redbean flour 50:50, which had average of moisture content of 2.21%, ash content of 2.53%, and protein contentof 9.07%. Sensory assessment of crackers by panelist showed that this crackers had a brown color, red beantaste, red bean flour, and rather hard textures.
