Abstract

Orange is one of the plants that cultivated and considered as horticultural plants. One of the regencies which have a lot of oranges crops is Banyuwangi and orange is one of the Banyuwangi commodities. The kind of orange which cultivated in Banyuwangi is Jeruk Siam (Citrus nobilis). Availability of oranges all of the years and the high of oranges consuming caused a lot of peel. To process orange peel be a product that have economics value that is be essentials oil. The aim of this research is to explore the diversity of volatile compounds of Citrus nobilis peel. The method used in this research is soxhletation which n-hexane as solvent. Extract was analyzed by using GCMS-QP2020 NX Shimadzu. Two of major volatile compound was identified as beta myrcene and dl-limonene which had Rt dan % area are 2.501 minutes, 3.75% and 3.113 minute, 41.08% the data was compared to Wiley 9 LIB. The data fragmentation (m/z) of beta myrcene are 41, 43, 53, 69, 93, 107, 121,136. The data fragmentation (m/z) of dl-limonene are 36, 41, 53, 68,79, 93, 107, 121, dan 136.

Abstract

Benzoic acid is an aromatic compound (C7H6O2), was found in plant and animal tissues, and also be produced from the fermentation process of microbial metabolism. Benzoic acid and its derivatives are widely used in agriculture, health and food. Because it’s functional, the reactivity of benzoic acid and its derivatives must be understood. One of the reactivity of benzoic acid is acidity. Acidity of benzoic acid is used to predicted reaction mechanism. Focus of this research is analysis the acidity of benzoic acid and its derivatives based on resonance theory and the effect of EWG (electron withdrawing groups) and DG (donating groups) to its acidity. The data in this research is collect by literature review on November 2024. In this research, it was found that the acidity of the benzoic acid and its derivatives was influenced by the type and position of the substituent. If the substituent is EWG, the acidity is increase and when substituent is DG, the acidity is decrease. These data can be explained by resonance.
