Abstract

The research about composition and structure of Arthropoda community was conducted at oil palm plantations Arthropoda were collected at oil palm plantation, conservasion forest and forest edge sites (between conservation forest and plantation area) by survey method with systematic random sampling for arthropoda in litter and soil. A total of four Arthropoda species that belonging to 2 orders, 3 families, 4 general and 57 individuals was collected. The highest number of individuals Isotomiella sp. (14 ind) family Isotomidae. Arthropoda community composition consists of 3 families & 4 species: Neanuridae (Lobella sp.), Brachystomellidae (Brachystomella sp.) & Isotomidae (Isotomiella sp. & Folsomides sp.), Arthropoda community structure The highest density is in the litter location I (16 ind / m2) while the lowest density is in location III (3.56 ind / m2). The highest soil density is in location I (4,538.56 ind / m3) & the lowest density is in location III (789,761 ind / m3). The highest relative density is location III (100%) & the lowest relative density is found in location I (litter, 5.8%) & (soil, 8.9%). The highest Shannon-Wiener diversity index, both litter and soil, were found in location I (litter 1.28) & (soil, 1.38) and the lowest diversity index was found in location III (0). The highest similarity index for Sorensen was location III (75.71%) and the lowest was the comparison between locations II & I (20%).

Abstract

Premna pubescens (wild leaves) has a rich history of traditional medicinal use, including as an anti-inflammatory, antioxidant, and anticancer agent. This study aimed to investigate the potential therapeutic effects of the ethanol extract of Premna pubescens leaves on erythrocyte count and kidney histology in Rattus norvegicus L. Twenty-four male Wistar rats were divided into four groups: control, ethanol extract of wild leaves, Sheep Red Blood Cell (SRBC) antigen, and combined ethanol extract with SRBC. The experiment involved administering wild leaf ethanol extract at 250 mg/kg BW for 30 days, followed by SRBC injection on days 8 and 15. Erythrocyte counts were measured, and kidney histological changes were observed.The results showed a significant increase in erythrocyte count in the A1 (7.42 ± 0.35 million cells/μl) and A3 groups (7.77 ± 0.23 million cells/μl) compared to the control group (7.05 ± 1.07 million cells/μl) and SRBC-treated rats (6.61 ± 0.18 million cells/μl). Histological analysis of the kidneys revealed clearer glomeruli and tubules, with reduced signs of inflammation and bleeding compared to the SRBC-treated group. These findings suggest that Premna pubescens extract has potential therapeutic effects on erythrocyte count and renal tissue, likely due to its antioxidant and anti-inflammatory properties. In conclusion, the ethanol extract of Premna pubescens shows promise in positively affecting erythrocyte count and mitigating kidney damage, demonstrating its potential as a therapeutic agent.
