Glucomannan was the main polysaccharide of Aloe vera gel. It was dissolved in water, formed a gel, and transparent as a film. Aloe vera gel was reported antimicrobial and antioxidant activity such as saponin and anthraquinone that was potential for the increased value of an edible film. However, Aloe vera gel form weak film caused glucomannan to have high water absorption. In this research, Aloe vera gel was used as a basis for the polymer film. Yellow sweet potato starch added for the strength matrix component used amylose. This starch expected to give colors from carotenoids. Glycerol also added for the flexibility of an edible film. Randomized Complete Block Design Factorial (RCBD) was applied. The first factor was concentration of yellow sweet potato starch (1%, 2%, 3%) and the second one was glycerol (0,1%, 0,25%, and 0,5%). The parameters tested were color, thickness, transparency, tensile strength, elongation, solubility, water vapor transmission rate, and inhibition zones against E. coli, and S. aureus, fungi A. niger and C. Albicans. The results showed that the addition of yellow sweet potato starch and glycerol with different concentration had a significant effect on color, thickness, transparency, tensile strength, elongation, and solubility. However, an edible film on this research has not to show bacteria and fungi inhibition zone of edible film. P2G1 is the best treatment (yellow sweet potato starch 2% and glycerol 0,1%) produced an edible film with a thickness of 0.12mm, elongation 50.85%, tensile strength 0.55 MPa, solubility 41.03%, transparency 2.13%, vapor transmission rate 3,40 g/m2/24hours, L, a+, b+ score in sequence 41.87, 0.2, and 4.1.

Edible films are thin layers made from hydrocolloids, lipids, and their combinations, functioning as a barrier to mass transfer. The hydrocolloid source that commonly used for edible film is starch. Lesser yam has the potential to be developed into food packaging products. It has a high starch yield (21.4%). The starch properties, which usually obstruct the edible film production are not resistant to high temperature, it produces a starch suspension with viscosity and ability to form a gel is not uniform, cannot stand in acidic conditions, does not resist stirring, limited solubility in water, and starch gel is easy to syneresis and brittle. This study aimed to investigate the effect of glycerol and Aloe veraconcentrations on the physical and mechanical edible film. Randomized complete block design (RCBD) factorial with two factors was adopted. The first factor was Aloe vera concentration (0, 1%, 0.2% and 0.3% w/v), and the second factor wasglycerol concentration (17.5, 22.5 and 27.5% v/w). The parameters tested included thickness, tensile strength, elongation, solubility, transparency, and water vapor transmission rate (WVTR). The results showed an interaction between the addition of glycerol and Aloe vera to thickness, tensile strength, elongation, solubility, transparency, and WVTR. The best characteristics of edible film were produced by the addition of glycerol 17.5% and Aloe vera 0.1% with thickness (0.08 mm), transparency (1.72 mm-1), tensile strength (0.156 MPa), elongation (17.25%), solubility (53.89%), and WVTR (4.09 g m-2 24 h-1).

Suweg tuber contains very high starch so that it can be used as one of the ingredients for the edible film. The use of a single ingredient from the starch group has a disadvantage because it has a weak and rigid, so it needs to be added ingredients to improve the nature of the edible film, namely by adding beeswax. The addition of beeswax is expected to improve the physical and mechanical properties of the edible film because its hydrophobic nature is a barrier to the loss of steam from products packed by the edible film. This research used a factorial randomized block design using two factors: suweg tuber starch concentration (3%.4%, and 5%) and beeswax concentration (1%.2%, and 3%). Parameters of research included analysis of raw materials in the form of water content, starch content and amylose starch content of suweg tubers whileanalysis edible film included the thickness, transparency, tensile strength, elongation, solubility, water vapor transmission rate and surface structure. The results showed that there was a very real interaction between the addition of suweg tuber and beeswax starch to thickness, elongation, tensile strength, and water vapor transmission rate and there was a real interaction with the transparency and solubility of edible film. The best treatment with near-standard results is edible film with suweg tuber starch concentration 3% (b/ v) and beeswax concentration 1% (b/ v) The surface structure of edible film on starch addition 3% (b/ v) results in a structure that more flat and soft, while the addition of beeswax 1% (b/ v) results in smaller pores.
