Abstract
Dalugha (Cyrtosperma merkusii (Hassk.) Schott) is a typical tuber in North Sulawesi. The locations are mostly in the Sangihe and Talaud Islands Regencies. Dalugha is a food source (carbohydrate) of the local community. Scientific studies about dalugha are still limited including the physiological characteristics of this plant. An important physiological characteristic of plants is the chlorophyll content. The purpose of this study was to determine the chlorophyll content of dalugha leaves in several places, the chlorophyll content of dalugha leaves from various leaf locations, and determine the relationship between chlorophyll content and dalugha cormus. The research locations were Pokol and Balane Villages, Sangihe Islands Regency, Bantik Resduk and Moronge Villages, Talaud Islands Regency, and the Experimental Gardens of Laikit and Lotta Villages from September 2019 to May 2020. This study used an observational approach, cross sectional study design or prevalence study. Data analysis of chlorophyll content and location and location of leaves using the statistical analysis method of variance (One Way ANOVA) and further tests of real honest difference (BNJ). Relationship between chlorophyll and dalugha cormus content using simple correlation statistical methods and coefficient of determination. The results showed that there were differences in the chlorophyll content of dalugha leaves between one location and another. Chlorophyll in Moronge Village 54.65 units, Balane 47.19 units, Bantik Resduk 44.19 units, Lotta 41.01 units, Pokol 38.78 units, Laikit 33.50 units. The chlorophyll content of dalugha leaves differs based on the location of the leaves. The upper part of the leaf is 46.89 units, the middle part is 43.89 units, and the lower part is 39.37 units. Chlorophyll content has a relationship with dalugha cormus production.
