Abstract

A type of fish suspected to have morphological characteristics similar to Nemacheilus spp was found in the Sibam River. However, the species has not yet been identified with certainty. This study aims to identify the types of Nemacheilus spp in the Sibam River based on morphometric and meristic characteristics. This study was conducted from September to November 2024. Sampling was conducted six times in the upper reaches of the Sibam River at two-week intervals. The fish samples obtained were then measured for their morphometric characteristics and counted for their meristic characteristics, followed by species identification based on relevant literature. The results showed that 38 Nemacheilus spp were caught, comprising 18 males and 20 females. Morphologically, male fish tended to have more contrasting and brighter body colors than females, which were relatively paler. Among the 24 morphometric characters observed, four characters showed differences between male and female fish, namely the head height (HH) of male fish was relatively shorter than females, the body height (BH) of female fish was higher than males, the distance from the dorsal fin to the caudal fin (DFCF) of males is longer than that of females, and the eye diameter (ED) of males is smaller than that of females. The meristic characteristics of male and female fish show similarities, with fin formulas D.II 6-8, P 9-12, V 6-7, A 4-5, and C 13-16.

Abstract

Cosmos caudatus is known as an herb that may improve fish health in general. However, the effects of this herb provision on the fish tissue structure have never been studied. To determine any changes in fish tissue provided with C. caudatus-enriched pellets, a study was conducted in June - August 2024. A CRD with 4 treatments: T0 (control), T1 (10 g/kg), T2 (15 g/kg), and T3 (20 g/kg), and 3 replications per treatment was applied. Commercial fish feed pellets were mixed with C. caudatus powder, and this feed was given to the experimental fish 3 times/day, at satiation. The fish was reared in saline media (5 ppt) for 60 days. By the end of the experiment, the tissue was removed and processed for histological study (formalin-fixed, alcohol series processed, 5mm sliced, HE-stained). Results showed that the provision of C. caudatus-enriched pellets does not affect the tissue structure of the fish in general, as the tissue structure was almost normal. However, abnormalities were observed in several fish, including the control fish, including hyperplasia and hemorrhage in the gills, glomerular damage and hemorrhage in kidney tissue, and hepatocyte damage in the liver. As the control fish that were not fed C. caudatus showed abnormalities in their tissues, it is predicted that the provision of C. caudatus may not cause the damage; instead, it may be related to other factors, such as water salinity. T1 (10 g/kg feed) had the highest survival rate at 96.66%. Based on the data provided, it can be concluded that the provision of C. caudatus-enriched pellets does not negatively affect the fish's tissue structure.

Abstract

This study aims to determine the types and abundances of phytoplankton species in Lubuk Larangan, Desa Sungai Paku. This research was conducted in May-June 2024 in Lubuk Larangan, Sungai Paku Village, Kampar Kiri District, Kampar Regency. The method used was the survey method, and data analysis was conducted using statistical tests. Phytoplankton species found in Lubuk Larangan, Sungai Paku Village, were 33 species belonging to 5 classes: Chlorophyceae, Cyanophyceae, Diatome, Euglenophyceae, and Zygnematophyceae. The abundance of phytoplankton species ranged from 7.080 to 16.800 cells/L. The highest phytoplankton abundance was at station II (16.800 cells/L), and the lowest was at station I (7.080,8 cells/L). Diversity index values ranged from 3.2883 to 3.7419, uniformity index 0.90 to 0.95, and dominance index 0.08 to 0.11. The high abundance of phytoplankton species obtained in the lubuk larangan (Station II) compared to the area outside the lubuk larangan (Stations I and III) indicates a difference type and abundance of phytoplankton with the results of the T test obtained a significant value of 0.028 (p < 0.05) and the value of T count is 3.374 and the value of T table is 2.77645 where T count is greater than T table

Abstract

Forest and land fires pose a serious threat to Pelalawan Regency, undermining environmental sustainability and community well-being. The Fire-Free Village (FFV) program serves as a preventive initiative that promotes active community participation and institutional collaboration. This study aims to analyze internal and external factors influencing the effectiveness of the FFV program and to formulate strategies for strengthening its implementation and adaptability to local conditions. A mixed-methods approach combined with SWOT analysis was employed, focusing on five program-supported villages. The findings indicate that strengths such as strong community participation and government policy support serve as key assets. At the same time, weaknesses and threats include limited resources and the persistent culture of land burning. Optimization strategies include enhancing human resource capacity, developing alternative economic activities, improving early-detection technologies, and promoting education grounded in local cultural values. These findings contribute significantly to the development of more effective and sustainable forest and land fire prevention strategies in Pelalawan Regency.
