The use of plastic can cause environmental pollution and risk the health of consumers. One of ways to solve this problem is the use of biodegradable packaging food is that edible film. Raw material for preparing edible film can be derived from starch, one of them is Breadfruit starch. Edible film can protect the packaged product of the oxidation process by adding orange skin extract. This research aimed at knowing physical and chemical characteristics of edible film of breadfruit starch with the addition of orange skin extract and the implementation of the source of student learning on Polymer material. Edible film was prepared from breadfruit starch with variation by adding 0, 2, 4 and 6 grs orange skin extract. Physical analysis was tested by using Water Vapor Transmission Rate and chemical analysis was tested by using Water Content and Antioxidant Activity Tests. Research findings showed that along with increasing the composition of orange skin extract, edible film was impairing of water vapor transmission rate, and increasing of water levels and antioxidant activity. Research product appropriateness of preparing edible film of Breadfruit starch with the addition of orange skin extract as the source of student learning on Polymer material was on the category of good (88.33%).Keywords: Edible Film, Starch, Breadfruit, Extract, Orange Skin

AbstractHuman needs on fossil fuels is increasing, but the source is limited. Thus, a renewable alternative source is needed. One of them is Biomass. Biomass fuel can be in the form of bio-briquette. Bio-briquette utilization as fuel is based on the carbon content contained in Biomass such as peat and bagasse. This research aimed at knowing bio-briquette quality as fuel and learning source at senior high school. Bio-briquette prepared with variation of peat and bagasse mass composition were 40: 0, 30: 10, 20: 20, 10: 30, 0: 40 (g: g). Bio-briquette was made by using 20 g adhesive kanji. Bio-briquette quality tested was done by testing the water content, ash content, volatile matter, fixed carbon, calorific value, and duration of flame. Bio-briquette the best quality is the mass variation of G 10g: 30g AT with water content of 3.93%, ash content of 6.33%, volatile matter of 46.60%, fixed carbon of 43.14%, calorific value of 5986 cal / g , duration of flame 210 minutes and the mass variation 0g G: 40g AT with water content of 2.33%, ash content of 3.83%, volatile matter of 49.47%, calorific value of 6198 cal / g, duration of flame 250 minutes. Preparing bio-briquette of peat and bagasse as learning source on chemistry material and its implementation was on the category of good (93.33%). Keywords: Bio-briquette, Peat, Bagasse, Quality test
