Abstract

Legumes are cultivated plants that are widely used by the community. In central Kalimantan, especially in Palangka Raya city, the legume is planted by the community as a garden plant which is consumed daily. The condition of acidic peatlands in Central Kalimantan is a limiting factor for plant growth. This study aims to determine the effect of peat water from the Sabangau River in Central Kalimantan on the germination of legume plants. The study used 4 (four) types of plants such as Vigna radiata L, Vigna unguiculata L, Phaseolus vulgaris L, and Glycine max L using a Completely Randomized Design (CRD). The plant seeds were first soaked in peat water for 3 (three) hours, then transferred to a medium covered with cotton and watered using the same water. Observations were made from the first day to the seventh day. The results showed that 3 (three) types of plants such as Vigna radiata L, Vigna unguiculata L, and Phaseolus vulgaris L were able to grow using peat water as a medium, while soybeans could not germinate. The results show that out of these three types of plants, Vigna radiata L has a better growth rate than Vigna unguiculata L and Phaseolus vulgaris L. Statistical tests using ANOVA analysis showed no significant differences between the three types of plants that grow.

Abstract

Butterflies are part of biodiversity that is important to be preserved because the presence of butterflies in an ecosystem, especially forests, is very important, both as part of the food chain, pollinators, and food for other animals. This study aims to analyze the species diversity and abundance of butterflies (Lepidoptera) in the habitat of Tahawa Village Forest Area, Pulang Pisau Regency. The research method used an exploratory survey method with a sweeping technique following a transect line and then calculated Shannon-Wiener Diversity Index (H'), Evenness Index (E), and Species Richness Index (R1). Butterflies found in the Tahawa Village Forest Area consisted of 6 families divided into 15 species with a total of 63 individuals. The most species found came from the Pieridae family and the least from the Geometridae family. The Diversity Index (H') obtained a value of 2.38, classified as moderate diversity. The Evenness Index (E) is in the high category with 0.88, while the Richness Index (R1) is at 3.38 which is still classified as low.
