The territory development will depend on that territory itself, where the word of autonomy for each province or territory will give contribution how Indonesian will responsible for development their territory. In order to develop territory, the information technology can be used as a boost or tools to give and deliver the best information and Geographic Information System is one of the informat...

Synthesis of Rosin Acid Starch Catalyzed by Lipase

Rosin, an abundant raw material from pine trees, was used as a starting material directly for the synthesis of rosin acid starch. The esterification reaction was catalyzed by lipase (Novozym 435) under mild conditions. Based on single factor experimentation, the optimal esterification conditions were obtained as follows: rosin acid/anhydrous glucose unit in the molar ratio 2:1, reaction time 4 ...

Synthesis, Characterization, and Bioactivity of Rosin Quaternary Ammonium Salt Derivatives

Two series of rosin quaternary ammonium salts (QAS) were synthesized using the same path. The structure of the target products was characterized by HPLC, MS, IR, and 1 HNMR, and the bioactivity was determined by filter paper method using Trametes versicolor (white-rot fungus) and Gloeophyllum trabeum (brown-rot fungus), which are two kinds of general wood decay fungi in nature. The results show...

Rosin an Important Polymer for Drug Delivery: a Short Review

Natural polymers are widely used in pharmaceutical formulations. They are biodegradable and generally nontoxic in nature. In this review pharmaceutical application of rosin is characterized. Rosin is a natural non-volatile resinous mass obtained from Pinus palustris. Physico-chemical characteristics and ease of availability of rosin provide a platform to use it as a polymer for different drug d...
