Robusta coffee is widely cultivated in Indonesia, and it is often processed into ground coffee. In this study, coffee jelly candy was made for product diversification of coffee. In this case, gel forming agents and sugar are needed to build jelly candy texture, aroma, and taste. The aim of this research was to study the characteristics of coffee jelly candy as affected by sucrose concentration and the ratio of carrageenan to gelatin. A completely randomized design using two factors (sucrose concentration of 40% and 60%; and gelatin to carrageenan ratio of 25:75, 50:50, and 75:25 w/w) was employed. The result showed that sucrose concentrations and gelatin to carrageenan ratio significantly (α > 5%) affected texture, color, moisture content, ash content, and organoleptic parameters (preference towards color, texture, taste, and overall). However, sucrose concentration and the ratio of gelatin to carrageenan not significantly (α < 0,05%) affect antioxidant activity and polyphenol concentration. The effectiveness test showed that coffee jelly candy with 40% sucrose concentration and the ratio of gelatin:carrageenan 50:50 had the highest score with L (lightness) value of 46.79, hardness of 54.53 g/mm, moisture content of 19.26%, ash content of 1.36%, antioxidant activity of 26.63%, total polyphenol of 0.46 mg GAE/mL, preference towards color of 5.60 (rather like), preferences towards aroma of 5.83 (rather like), preferences towards taste of 5.10 (rather like), preferences towards texture of 5.13 (rather like), and overall preference of 5.57 (rather like). Keywords: carrageenan, gelatin, jelly candy, organoleptic, robusta, sucrose

This research aimed was to determine the effect of temperature and duration of withering on the characteristics of herbal tea of kenikir leaves (Cosmos caudatus Kunth.) and to know the right temperature and duration of withering time to get the best characteristics of herbal tea. The experimental design used was Completely Randomized Design with two factors which were withering temperature (70oC, 80OC, and 90oC) and withering duration (1, 2, and 3 minutes). All of the treatment was repeated two times to obtain 18 units of experiments. The data obtained were analyzed by variance and if the treatment had a significant effect followed by The Duncan Multiple Range Test. The results showed that interaction of temperature and withering time had a very significant effect on moisture content, total phenolics, total flavonoids, antioxidant activity, and color (scoring test). The results showed that interaction 90oC of withering temperature during 2 minutes was the best treatment to produce kenikir leaves herbal tea with the moisture content 6,76% b/b, extract content 32,89%, vitamin C 3,35 mg /g total phenolics 79,26 mg GAE/g, total flavonoids 161,01 mg QE/g and antioxidant activity 74,29% with IC50 valued 24,409 ppm.

This study aims to determine the effect of the proportion of brown rice flour and seaweed flour on the antioxidant activity of iwel, a traditional Lombok cake. This study used a completely randomized design (CRD) with one factor, namely the proportion of brown rice flour and seaweed flour with 6 treatments, namely K0 (100%: 0%), K1 (90%: 10%), K2 (80%: 20) , K3 (70%: 30%), K4 (60%: 40%) and K5 (50%: 50%). Each treatment was repeated 3 times in order to obtain 18 experimental units. The chemical parameters observed included chemical parameters (antioxidant activity, moisture content, ash content), and organoleptic parameters (texture, color, taste and odor) by hedonic and scoring. Observation data were analyzed using Analysis of Variance at the 5% real level using Co-stat software. If there is a significant difference, a further test is carried out using Orthogonal Polynomials for chemical parameters and Honest Significant Difference (BNJ) at the 5% level for organoleptic parameters. The results showed that the higher the addition of seaweed flour caused a decreased in antioxidant activity, moisture content, and preference of panelists but increased ash content of iwel. The proportion of brown rice flour and seaweed flour at K2 was the best treatment seen from the antioxidant activity of 58.80%; moisture content 17.13%; and the ash content of 3.94% and the panelists prefer a bit chewy texture, red color, taste of brown rice flour and had not smell of seaweed.

Cassava is also known as cassava, an annual tropical and sub-tropical tree from the Euphorbiaceae family. Tubers widely recognized as staple foods. Cassava has advantages compared to other food ingredients. Aside from being a staple food, many kinds of cassava processed products have utilized by our community, including cassava crackers. This study used a Completely Randomized Design (CRD) with 5 (five) treatments and 4 (four) replications or 5 x 4 to obtain 20 experimental units. The treatment factor is steaming length, which consists of 5 levels of steaming time as follows: A: 30 minutes, B: 60 minutes, C: 90 minutes, D: 120 minutes, E: 150 minutes. The quality of cassava crackers to be tested or measured based on their physical appearance is related to consumer acceptance. In conducting organoleptic testing, panelists influenced by several factors. Factors that influence panelists include physical factors and psychological factors. The organoleptic parameters observed included color, taste, and degree of crispness. Laboratory tests include carbohydrate tests, water content, ash content, protein, and fat content. The conclusion was that the effect of steaming time had no significant effect on moisture content, ash content, protein, and crispness, while the effect of steaming duration had a significant impact on the levels of fat, carbohydrate, taste, and color in cassava crackers. The best quality of the five treatments was treatment 5 (p5), ie, steaming time with 150 minutes
