Abstract

Synthesis is an integration of two or more existing elements to produce a new result. Key orange (Citrus x microcarpa Bunge) is a Bangka Belitung plant that contains citric acid with a high acidic taste. Its high acidic nature can be used as a catalyst that can accelerate the reaction rate in synthesizing an α-terpineol compound from α-pinene contained in broomstick essential oil. The synthesis of α-terpineol can be done using combined and uncombined catalysts, namely 15% sulfuric acid, 99.5% acetic acid and natural citric acid from key lime juice. This study aims to determine the optimum composition of the catalyst combination of sulfuric acid, acetic acid and key lime juice in synthesizing α-terpineol compounds and the level of α-terpineol produced from the synthesis. The optimum result of the combination of catalysts that can synthesize α-pinene into α-terpineol quite well is using 15% sulfuric acid as much as 1 ml, 99.5% acetic acid as much as 1 ml and citric acid from key orange juice as much as 3 ml. The results of α-terpineol content of each catalyst are Product 1 by 33.14%, Product 2 by 6.36%, Product 3 by 1.00%, Product 4 by 17.32% and Product 5 by 18.43%.

Abstract

Sempan Village is one of the villages in Pemali District of Bangka Regency, Bangka Belitung Islands which do not yet have the featured products, while this village has nipah plants that are not used optimally. The nipah fruit can be further processed into a featured product of village i.e. syrup. The service program Chemistry Department is training Sempan Village society on the manufacture of syrup from nipah fruit. The method of this activity includes three stages i.e. preparation, implementation and evaluation. After this activity is carried out, the Sempan Village society have increased understanding, knowledge and motivation in utilizing nipah fruit into processed syrup products and this product is expected become one of the featured products of Sempan VillageKeywords: nipah fruit, syrup, Sempan Village

Abstract

A cellulose derivative substance called cellulose acetate is frequently used in the manufacturing of photographic film, fiber, membranes, and bioplastics. However, the availability of sources for cellulose acetate's raw material does not support this demand. Paper waste has a high cellulose content. Therefore, the aim of this research is to synthesize cellulose acetate from α-cellulose waste paper. In order to separate alpha cellulose from waste paper in this study, the delignification process with NaOH solvent was used as a first step. After obtaining alpha cellulose, acetic anhydride was used to carry out the acetylation reaction. The yield of α-cellulose from paper waste is 51.8%. α-Cellulose is reacted with acetic anhydride through acetylation reactions and hydrolysis of acetyl groups. From this reaction, functional groups -OH, C=O ester, and C-O acetyl appeared from the FTIR spectra analysis which indicated that cellulose acetate had been successfully synthesized. The type of cellulose acetate produced is a type of cellulose monoacetate with an acetyl groups of 23% and a degree of substitution value of 1.17.
