Development of Cascara Tisane with The Addition of Dried Pineapple (Ananas sativus) and Rosella Flower (Hibiscus sabdariffa)
Coffee cherry skin, a form of coffee production waste that accounts for up to 60% of the total yield, contains natural antioxidants that have the potential to become functional foods. Cascara Tisane is a brewed beverage derived from dried coffee cherry skin. Adding other ingredients to this product can help increase consumer acceptance in Indonesia. In this study, the additional ingredients used were dried pineapple and rosella flowers. To determine the effect of adding these ingredients, it is necessary to identify the drying temperature and chemical and organoleptic characteristics to produce Cascara Tisane products according to the Indonesian National Standard (SNI). The research consisted of two stages, namely (1) the identification of the drying temperature of coffee cherry skin and (2) the formulation of the addition of dried pineapple and rosella. The drying temperatures used were 45 oC, 50 oC, 55 oC, and 60 oC. The sample formulation consists of four levels, namely code 126 (75% coffee cherry skin, 15% dried pineapple, 10% rosella): 216 (65% coffee cherry skin, 20% dried pineapple, 15% rosella); and 616 (55% coffee cherry skin, 25% dried pineapple, 20% rosella). Chemical characteristics analysis was conducted on moisture and ash contents, as well as antioxidant activity. Furthermore, a hedonic test was used to evaluate cascara tisane products' organoleptic characteristics (aroma, taste, color, and aftertaste) with a 5-point hedonic scale. The results showed the optimum drying temperature of coffee cherry skin at 45 oC, with the most preferred formula being formula 616
Production of Biodegradable Straw from Banana Peel
This study aims to determine the effect of enhancement in stirring temperature (75oC, 80oC, 85oC) and type of plasticizer (glycerol and sorbitol) on the characteristics of biodegradable straw from ambon banana peel waste and to compare them with the characteristics of conventional boba’s straws. Methods used in this study were tensile strength, elongation, biodegradation, and water uptake tests. The result showed enhancement of stirring temperature and type of plasticizer did not significantly affect the characteristics of biodegradable straws from ambon banana peel waste (p > 0.05). Enhancement of stirring temperature will increase the tensile strength and water resistance value, but decreased elongation and biodegradation value because enhancement of stirring temperature will decrease the water content and increase the molecular density. In addition, plasticizer will increase elongation value and level of biodegradation, but decrease tensile strength and water resistance values. Plasticizer has the ability to increase the elasticity of polymers, as well as increase water absorption because it has hydrophilic hydroxyl groups. Biodegradable straw that have been developed has a colour of black, being rigid, with a length of 13 cm and an external diameter of 1.2 cm. The colour and external diameter of biodegradable boba’s straw looks similar with conventional boba’s straw but shorter in length. Therefore, ambon banana peel waste was promising to be used as an alternative material for biodegradable straw in the future
Development of Sago Analog Rice with The Addition of Glucomannan Flour Using Value Engineering Method
Analog rice is an imitation of rice made with non-rice ingredients such as tubers and cereals as an alternative healthy food. However, the existence of analog rice has not been fully known and accepted by the public due to a lack of knowledge. The physical characteristics of analog rice do not resemble paddy rice and still have several attributes that interfere with consumer acceptance. Adding glucomannan to make analog rice is expected to improve product attributes. This study aims to determine the priority of product development attributes and produce analog rice with the best concept through high value. The method used in this product development is value engineering, which has five steps: information, creativity, analysis, development, and recommendation steps. The best concept for analogs is rice made from sago with an additional composition of 0.07 gram glucomannan flour and 7 ml pandan essence oil. Sago analog rice with 0.07 grams of glucomannan and 7 ml pandan essence oil has 83.74% carbohydrate, 3.02% fat, 4.53% protein, 8.15% water content, and 0.55% ash content.

Potential Utilization of Sesame Seed Coat as Raw Material for Flour Production
Sesame seed coat is a by-product from hulled sesame seed industry which has high nutritional content but still has low economic value because it is only used in animal feeding. The purpose of this study is to explore the potential of sesame seed coat as a raw material for making flour by looking at the protein content, dietary fiber, food safety, and antioxidant potential so it can be recovered and used as a value added product. Temperature and time in drying can be the factor that determines the final quality. This study was conducted to investigate the best experimental design in combination of drying temperature and time to acquire the best water content, protein content and fiber content on flour. Testing for microbial contamination with total yeast and mold count and testing for chemical contamination of heavy metals such as mercury (Hg), cadmium (Cd), and lead (Pb) were also carried out to ensure food safety. Testing for antioxidant activity and ferulic acid content were also carried out to determine the potential of sesame seed coat flour as an antioxidant-rich food. The results of this study showed that the best temperature and drying time for making sesame seed coat flour was 60oC and 6 hours. In that conditions, the water content, protein content, total dietary fiber content, antioxidant activity, and ferulic acid content were 13,3333%, 7,3537%, 21,6947, 5.871,2381 ppm, and 8,749 mg/kg respectfully for each category. In the microbial test, the results showed that the number of molds and yeast was 8 x 103 colonies/g, while for the chemical contamination test, it was 0.04 mg/kg for mercury, 0.67 mg/kg for cadmium, and undetectable amount for lead
