A study on the absorption of carbon dioxide (CO₂) in the plant was conducted at low land and private highland forest. The purpose of this study was to get plant species with high CO₂ absorption in both lowland and upland of the private forest. The study used a survey method. The location was grouped into two strata, namely lowland and highland of the private forest. The sample of composition of the private forest vegetation at both lowland and highlands location was carried out by using quadrat 10 m x 10 m. The capacity of the plant CO₂ absorption was analyzed through the mass of carbohydrates. The results showed that there are 27 species of plants that consistently composed at both strata of private forest. These species consist of both trees, and crops with the number of species were 21 and 6 species, respectively. Species of trees that have a high absorption of CO₂ are Tectona grandis, Neolamarckia cadamba, Havea brasiliensis, Coffeea robusta, Gmelina arborea, Cocos nucifera, Mangifera indica, Hibiscus macrophyllus, Canna edulis, Vigna sinensis, Zea mays, and Calocasia esculenta. The results of this study can be used as a basis for preparing a sustainable private forest pattern-based on the high absorption of CO₂.

在低地和私人高地森林中进行了植物吸收二氧化碳（CO _{2 ）的研究。}本研究的目的是在私人森林的低地和高地获得具有高 CO _{2吸收的植物物种。}该研究采用了调查方法。该位置分为两层，即私人森林的低地和高地。使用样方 10 mx 10 m 进行低地和高地私人森林植被组成的样本。_{工厂 CO 2}的容量通过碳水化合物的质量分析吸收。结果表明，在私人森林的两层中，共有27种植物一致组成。这些物种由树木和作物组成，物种数量分别为21种和6种。CO ₂吸收率高的树种有Tectona grandis、Neolamarckia cadamba、Havea brasiliensis、Coffea robusta、Gmelina arborea、Cocos nucifera、Mangifera indica、Hibiscus macrophyllus、Canna edulis、Vigna sinensis、Zea mays和Calocasia esculenta。_{本研究结果可作为构建基于高吸收CO 2}的可持续私有林格局的基础。
