Cassava, corn, sago and the other food crops have been commonly used as raw materials to produce green plastics. However, plastics produced from such crops cannot be tailored to fit a particular requirement due to their poor water resistance and mechanical properties. Nowadays, researchers are hence looking to get alternative raw materials from the other sustainable resources to produce plastics. Their recent published studies have reported that marine red algae, that has been already widely used as a raw material for producing biofuels, is one of the potential algae crops that can be turned into plastics. In this work, Eucheuma Cottonii, that is one of the red alga crops, was used as raw material to produce plastics by using a filtration technique. Selected latex of Artocarpus altilis and Calostropis gigantea was separately then blended with bioplastics derived from the red algae, to replace use of glycerol as plasticizer. Role of the glycerol and the selected latex on physical and mechanical properties of the red algae bioplastics obtained under a tensile test performed at room temperature are discussed. Tensile strength of some starch-based plastics collected from some recent references is also presented in this paperDoi: 10.12777/ijse.5.2.81-88 [How to cite this article: Machmud, M.N., Fahmi, R., Abdullah, R., and Kokarkin, C.

Chicory (Brassica pekinensis L.), a leaf vegetable that can grow in subtropical and tropical climates, has high economic value, but its production is still relatively small. The provision of BSF and PGPR frass is expected to increase soil organic matter content and nutrient availability for chicory plants. This experiment was carried out at the Experimental Garden, Cikidang Village, Lembang District, West BandunggRegency, at an altitudeeof 1,250 meterssabove sea level, in the Andisol soil order. This study aims to study the interaction between different doses of cassava and the best concentrations of bamboo root PGPR on the growth and yield of mustard plants. The study used a factorial Randomized Block Design (RBD) with two factors, namely BSF frass doses, namely 0 g, 25 g, 50 g, and 75 g, and PGPR concentrations of bamboo roots, concentrations of 0 ml/L water, 10 ml/L water, 20 ml/L water, and 30 ml/L water; each treatment was repeated four times. The results showed no interaction between BSF frass doses and bamboo root PGPR concentrations on the growth and yield of chicory plants. The presence of bamboo roots' PGPR and BSF frass causes the chicory plants' high response at 30 HST. The best dose of chicken manure is 75 grams per plant, and the PGPR concentration of bamboo roots is 10 ml per liter of water. Keywords: Chicken Manure Kasgot, Bamboo Root PGPR, Chinensis cabbage
