IDENTIFIKASI MORFOLOGI DAUN TANAMAN AREN DI KECAMATAN ANGKOLA BARAT

Abstract

This study aims to determine the morphological diversity of palm leaves in plants that are producing sap. This research was conducted in Sitaratoit Village, West Angkola District. The research method using survey methods and data collection directly at a predetermined location, by identifying plant morphology of leaves in the population of the community sugar palm plant. The data obtained were analyzed using cluster analysis with the K means method, to group objects that have similar characteristics so as to form certain groups called clusters. Observed parameters, qualitative parameters; leaf seated direction and quantitative parameters; number of productive leaves, leaf length, leaf width, leaf length, number of leaflets, number of unproductive leaves, diameter of male flower stalks and sap production. The results showed that the average direction of sitting palm leaves in the village of Sitaratoit was to the left. While the results of quantitative parameter analysis obtained 2 clusters, cluster 1 has the lowest number of members, amounting to 6 sample plants consisting of sample plants 1, 6, 7, 8, 10 and 12. While the most numerous are cluster 2 with a total membership of 14 sample plants consisting of sample plants 2, 3, 4, 5, 9, 11, 13, 14, 15, 16, 17, 18, 19 and 20. The parameter that has the highest F number is the leaf length that is equal to 39,096 with values ​​in the column Sig. is 0,000 which means it's significantly different. This shows that the leaf length character is the distinguishing factor of the two clusters. Cluster 2 is the biggest cluster because it has more sample plants, while cluster 2 has lower leaf length than cluster length 1
