Abstract

Pressure on coastal water conditions in Manokwari caused by human activities can affect the morphometric adaptation of seagrass plants, one of which is Halophila ovalis. The study aimed to analyze the morphometric differences of Halophila ovalis caused by differences in environmental factors on several coastal areas in Manokwari. A total of 20 samples of H. ovalis were taken from each of the beaches studied and then four morphological characters were measured. Morphometric data of H. ovalis between locations were analyzed using analysis of variance (ANOVA), then continued with non-multidimensional scaling (NMDS) analysis. The results showed that there were changes in the morphometrics of H. ovalis from the four research locations. Specifically, it was found that the H. ovalis with the most different morphology came from Rendani Beach. NMDS analysis shows that the morphometrics of H. ovalis on Rendani Beach are separate from  from Yenkarwar, Wosi and Saubeba Beaches. The NMDS model was explain 74.19% of the morphometric diversity influenced by environmental parameters such as water temperature, substrate conditions, pH, salinity, and dissolved oxygen levels. We concluded that there had been morphometric changes in the seagrass H. ovalis in several coastal waters in Manokwari.

Abstract

Indigenous Papuans utilize plants around them for traditional medicine. This study aims to determine the types of traditional medicinal plants used by indigenous Papuans in Sairo Village and Lebau Village, as well as the content of secondary metabolites of these plants to enrich pharmacological data. The method used was interviews and field surveys followed by phytochemical screening to determine the content of compounds in plants used as medicine. The results obtained in this study are 27 types of medicinal plants used by indigenous Papuans in in Sairo Village and Lebau Village of Manokwari Regency. Plant parts are utilized and the way they are used varies for various diseases. The results of phytochemical screening show that there are saponins, alkaloids and tannins that vary in medicinal plants.

Abstract

Daun gatal (Laportea decumana (Roxb.) Wedd.) is a medicinal plant traditionally used by local Papuan communities as a physical therapy to relieve fatigue, muscle pain, and body aches. However, the ecological aspects of its cultivation remain poorly understood. This study aimed to compare the leaf morphological variables of daun gatal cultivated under shaded and unshaded conditions. Field observations were conducted alongside leaf morphometric analysis and examination of leaf trichome characteristics to strengthen the analytical results. The findings indicated that air temperature, air humidity, and sunlight intensity were positively correlated (~0.80) with plant height, leaf area, trichome length, and trichome density in plants grown under shaded conditions. Meanwhile, plant height and stem diameter did not differ significantly (P>0.05) between shaded and unshaded treatments. In contrast, leaf length, leaf width, and leaf area showed significant differences (P<0.05) between the two treatments. Trichomes of plants grown in shaded habitats were significantly longer than those in unshaded habitats (P<0.05). Trichome density exhibited a similar pattern, being higher in shaded areas than in unshaded areas, although the difference was not statistically significant (P>0.05). Overall, this study demonstrates that the daun gatal exhibits morphological adaptations to variations in light intensity within its habitat, providing an important scientific basis for the effective management and optimal cultivation of Laportea decumana in Manokwari Regency.
