Abstract

Penelitian ini bertujuan mengkaji karakteristik morfologi, anatomi, kandungan fitokimia, dan klorofil daun tiga spesies famili Fabaceae (Acacia auriculiformis, Dendrolobium umbellatum, dan Cynometra ramiflora) yang tumbuh di Taman Wisata Alam (TWA) Pananjung, Pangandaran. Penelitian ini diharapkan menjadi penelitian dasar tentang potensi spesies Fabaceae dalam bidang farmasi, pertanian, dan konservasi sumber daya alam. Penelitian dilakukan secara observasional melalui pengamatan morfologi dan anatomi daun, pengujian fitokimia secara kualitatif (alkaloid, tanin, dan saponin), serta kadar klorofil daun. Hasil penelitian menunjukkan ada perbedaan karakteristik morfologi, anatomi, dan profil fitokimia antar spesies. A. auriculiformis dan C. ramiflora mengandung alkaloid dan saponin. D. umbellatum mengandung tanin dan saponin. Species yang mengandung klorofil dari yang tertinggi ke terendah secara berurutan adalah C. ramiflora, D. umbellatum, dan A. auriculiformis. Faktor lingkungan yang terukur adalah 859.33-7474 lux untuk intensitas cahaya, 75-83,67% untuk kelembapan udara, 29,23-30,4°C untuk temperatur udara, 6,6-6,93 untuk pH tanah, <2 mg/kg untuk kadar nitrogen tanah, <6,67 mg/kg untuk kadar fosfor tanah, serta <2,34 mg/kg untuk kadar unsur kalium tanah.

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.
