Abstract

Muntingia calabura (kersen) is a tropical plant with high adaptability that reproduces generatively through seeds. This study aimed to determine the generative reproduction process of kersen through natural seed germination and to observe the early growth and adaptive response of the plant after being transplanted into planting media. The method used was observation with a descriptive approach. The study was conducted for approximately 14 days, using young plants resulting from natural germination as the research objects. The procedures included collecting seedlings, transplanting them into planting media, and observing plant growth. The results showed that the plant did not exhibit significant height growth, remaining at approximately 15 cm, and the number of leaves decreased from 8 to 6 due to leaf yellowing and abscission. This condition indicates the occurrence of transplant shock after relocation to new planting media. However, the plant maintained an upright stem, indicating its ability to survive. Therefore, generative reproduction through seeds is the main mechanism of kersen propagation, although early plant growth is strongly influenced by environmental conditions and adaptation processes.

Abstract

Coastal ecosystems consist of lively habitats marked by elevated temperatures, salinity levels, significant wind exposure, and minimal soil moisture, all of which affect the growth and spread of plant species. The coconut tree (Cocos nucifera) stands out as a prevalent species in tropical coastal regions owing to its exceptional ability to adapt. The objective of this research is to assess the bioecological traits of coconut trees located at Kuranji Beach, in the West Lombok Regency, through direct environmental observations. The study utilized a descriptive observational approach, focusing on measurements of soil temperature, soil acidity, and moisture levels in the soil. Findings revealed that the soil temperature was at 35°C, soil pH measured between 7 and 7.5 (indicating neutrality to slight alkalinity), while soil moisture was identified as low (indicating dry conditions). These results suggest that the coastal habitat imposes challenges for plant development; nonetheless, coconut trees show significant adaptation capabilities through both structural and functional responses. This research highlights the crucial ecological role that coconut vegetation plays in sustaining coastal durability and resilience.
