The purpose of this study is to determine the structure of regional revenues and analyze the shift in leading sectors in Kampar Regency from 2010 to 2019. The data used are the Central Statistics Agency of Kampar Regency, the Central Statistics Agency of Riau Province, the Regional Development Planning Agency and other sources such as the internet and literature study. The analysis was carried out with a descriptive method using a quantitative approach. In this study using location quetient (LQ) analysis tools, shift share, typology class. The results of the analysis show that Kampar Regency in running its government and its economy still depends on the transfer of central government funds and the analysis also shows a shift in the leading sectors in Kampar Regency, such as the manufacturing sector and the health service sector and social activities from 2010 to 2014 2015 - 2019.

Abstract

Mango is one type of fruit that is most popular with the public. The use of mangoes is only for the flesh for consumption, while the skin and seeds are discarded, causing organic waste in the environment. This study aims to determine the content of secondary metabolites and antioxidant activity in the seeds of arum manis mango (Mangifera indica Linn.), kweni mango (Mangifera odorata Griff.) and bacang mango (Mangifera foetida Lour.). Mango seed extract was made by maceration method using 70% methanol solvent. The phytochemical test was carried out qualitatively and the antioxidant activity test was carried out using the DPPH (2,2-diphenyl-1- picrihidrazyl) method. The results of the phytochemical tests showed that the methanol extracts from the seeds of arum manis, kweni and bacang mangoes contained the same secondary metabolites, namely alkaloids, flavonoids, triterpenoids, tannins and saponins. Bacang mango seeds have a higher content of secondary metabolites compared to arum manis and kweni mango seeds. Antioxidant activity test showed that the methanol extract of arummanis, kweni and bacang mango seeds had an IC value below 50 which was classified as very strong antioxidant activity. Of the three samples, arum manis mango seed extract had the strongest antioxidant activity (2.84 µg/mL) compared to bacang mango seeds (2.85 µg/mL) and kweni (3.22 µg/mL).
