The type of this research was Research and Development (R & D). The measures used in this study refer to Sugiyono (2013) which have been modified into the steps of: 1) Doing the needs analysis 2) Developing the initial product 3) Validating to the experts and legibility 4) Revising Product and 5) Analyzing the data. The results showed that the validation score of teaching materials in the form of handouts feasibility aspects of the content was 88.23% (highly valid), the presentation of the feasibility aspects was 91.66% (highly valid), feasibility aspects of language was
93.26% (highly valid) and students test legibility was 87.50% (excellent). From the assessment of expert validation and test of legibility students the teaching materials, the handout on palm tree population structure (Arenga pinnata Merr.) in Rampah Manjangan waterfall Loksado was highly valid and very well used as a supplementary material on ecological plants population concepts in Biology Education Department, Universitas Lambung Mangkurat, Banjarmasin.
