Chemical Content Study of Salak Sidimpuan (Salacca sumatrana Becc.) Fruit Based on Altitude

Salak can grow well in the lowlands at an altitude of 200 m above sea level to an altitude of 700 meters above sea level with a wet climate type. The desired environment has a pH of 5-7, rainfall of 1500-3000 mm per year with a dry season of four to six months. The purpose of this study was to determine the differences in soluble sugar content, vitamin C content and total titratable acid of Sidimpuan salak fruit (Salacca sumatrana Becc) based on the three classifications of altitude. This research has been carried out in West Angkola District in three locations with an altitude of 500-650m above sea level, Padangsidimpuan Hutaimbaru in 3 garden locations with an altitude of 400-500 m above sea level and South Angkola there are 3 with an altitude of 200-300 m above sea level, starting in August to September 2021. Based on the results of this study, it is concluded that the difference in altitude of the place does not significantly affect the dissolved sugar content and vitamin C of Sidimpuan salak fruit but the altitude of the place has a significant effect on the total titratable acid of salak fruit, namely 1.4011% in West Angkola and 0.9822% Padangsidimpuan Hutaimbaru sub-district and South Angkola 1.2644%.
