Abstract

This study aims to analyze the use of digital media in overcoming learning boredom in IPAS at the elementary school level. Learning boredom is often caused by monotonous teaching methods, limited learning media, and low student engagement. This research uses a literature review method by examining relevant studies published between 2020 and 2025. The results show that digital media such as learning videos, animations, interactive applications, and educational games can create a more engaging and interactive learning environment. These media help increase students’ motivation, participation, and understanding of abstract concepts through visual and audiovisual presentations. However, the implementation of digital media still faces challenges, including limited teacher competence, inadequate facilities, and low digital literacy among students. Therefore, efforts such as teacher training, improving infrastructure, and collaboration between schools and parents are needed. In conclusion, digital media play an important role in reducing learning boredom and improving the quality of IPAS learning in elementary schools.

Abstract

Acclimatization is the last and critical stage in the in vitro culture of Musa paradisiaca L. var. kepok tanjung. The primary hardening phase of acclimatization is carried out so that plantlets can adapt from heterotrophic conditions to autotrophic conditions. This study aims to optimize the acclimatization media for M. paradisiaca L. var. kepok tanjung plantlets, an important factor in the acclimatization process. A completely randomized design was applied in this study using 13 different combinations of soil, cocopeat, and charcoal husk media. The observation parameters included morphological parameters (height, number of leaves, leaf area, pseudo-stem diameter, and survival rate) and physiological parameters (wet weight, dry weight, relative water content (RWC), and chlorophyll content index (CCI), which were analyzed using ANOVA or Kruskal-Wallis according to data assumptions. The results showed that all media combinations produced a 100% survival rate, with the best results shown by the cocopeat: charcoal husk (1:1) combination. This media combination provided the highest increase in height (1.05 ± 0.11 cm), pseudo-stem diameter (1.15 ± 0.12 mm), number of leaves (0.75 leaves), leaf area (121.06 ± 20 cm²), fresh weight (8.23 ± 2.99 g), dry weight (0.45 ± 0.16 g), CCI (23.2 ± 3.63), and the highest relative water content (98.47%). The combination of cocopeat and husk charcoal (1:1) was able to maintain moisture and provide good aeration for plantlet growth. Therefore, the combination of cocopeat and charcoal husk (1:1) is recommended as the most effective media for acclimatizing M. paradisiaca L. var. kepok tanjung plantlets in the primary hardening phase.

Abstract

This study aimed to assess the ability of water hyacinth (Eichhornia crassipes) as a bioaccumulator of heavy metals copper (Cu) and zinc (Zn) in rubber industry wastewater at PT Batanghari, Bengkulu. The research methods included water and water hyacinth sampling from effluent ponds and controls, followed by analysis of Cu and Zn levels using atomic absorption spectrophotometry (AAS). Results showed that Zn levels in wastewater reached 143.0884 mg/l (28 times the quality standard), while Cu was 0.1845 mg/l (still below the quality standard). Water hyacinth accumulated metals in different patterns: Cu was highest in the roots (1.4480 mg/l), while Zn was evenly distributed in the roots (6.7261 mg/l) and leaves (6.6473 mg/l). Analysis of bioaccumulation (BAF) and translocation factors (TF) revealed the efficiency of water hyacinth in absorbing metals, especially Zn, although the absorption mechanism is selective and influenced by environmental conditions such as pH, dissolved oxygen, and the presence of organic compounds. The implications of this study emphasize the potential of water hyacinth as an economical and sustainable phytoremediation solution for the rubber industry, with recommendations of implementing a constructed wetland system and periodic harvesting for optimization.

Abstract

This study aims to compare the salt content (NaCl) in the leaves of several types of coastal plants that grow in different formations, namely Mangrove, Barringtonia, and Pres-Caprae. The study was conducted in the coastal area of Lais District, North Bengkulu Regency using direct survey methods in the field and laboratory analysis using a refractometer. The results showed that there were 10 species of coastal plants from three formations, namely Barringtonia, Mangrove, and Pes-Caprae. The highest salt content was found in the Acanthus species ilicifolius (2.75‰) from the Mangrove formation, while the lowest levels were found in Canavalia maritima (0.75‰) from the Pes-Caprae formation. The difference in salt content is thought to be influenced by the location of its habitat in the coastal area and its ability to adapt both structurally and physiologically so that it can survive in an environment with extreme salt content. The results of this study provide important information about the adaptation of coastal plants to salinity and can be the basis for further research on salt concentration in coastal plants.

Abstract

This study investigates the phytochemical content and morpho-anatomical characteristics of Celosia argentea L. plants grown under different light intensities in the Embung Leuwi Padjadjaran area. Leaf samples were collected from shaded and unshaded locations to compare their responses to varying light conditions. Phytochemical analysis revealed that plants in higher light intensity areas tended to have increased levels of specific phytochemical compounds, which is crucial for the plant's defense mechanisms. Furthermore, the research found morphological and anatomical differences, such as greater leaf thickness and a lower stomatal density in unshaded plants. Conversely, shaded plants exhibited higher chlorophyll content and larger leaf areas, which are adapted to low-light environments. The study concludes that varying light intensity significantly influences the morpho-anatomical features and phytochemical composition of Celosia argentea L., with shaded conditions promoting adaptations for light capture and unshaded conditions increasing certain phytochemicals and leaf thickness.
