Abstract

Curcuma sumatrana or Koenih Rimbo, is an endemic plant of West Sumatra that is threatened with extinction due to deforestation, climate change, and human activities. This study aims to understand the ecology of C. sumatrana to support effective conservation efforts. The study was conducted in seven potential locations in West Sumatra using exploration methods and analysis of environmental factors, such as altitude, temperature, humidity, soil pH, and canopy cover. The results showed that this species was only found in three locations, namely Lubuk Kilangan, Koto Malintang, and Koto Pulai, with the highest population in Koto Malintang. Environmental factors such as altitude, canopy cover, and air humidity were shown to support optimal growth of this species. Canonical Correspondence Analysis (CCA) identified a close relationship between environmental factors and morphological parameters, including plant height, number of branches, and leaf size. This study emphasizes the importance of natural habitat conservation and further research on the ecology of this species to prevent its extinction.

Abstract

Tomato (Solanum lycopersicum L.) is one of the horticultural commodities with high economic value whose growth is greatly influenced by environmental conditions. This study aims to examine the phenology of tomato plants, including the time of flowering and flowering duration in different environmental conditions as a basis for developing more effective cultivation techniques. The study was conducted in two locations, namely Kamang Magek District and Padang City, with 20 replications per location. Phenology observations were carried out on the time of flowering and flowering duration of tomato plants, and the data obtained were analyzed using the t-test at a significance level of 5%. The results showed a significant difference between the two locations, where the average time of flowering in Kamang Magek District was 38.5 days after planting (DAP) with a flowering duration of 10.85 days, while in Padang City the time of flowering occurred at 75.8 DAP with a flowering duration of 30.3 days. This difference indicates that environmental conditions in Kamang Magek District are more supportive of accelerating the flowering phase with a shorter flowering cycle.
