Abstract

This study examines the stomatal characteristics and leaf thickness of six species within the Liliales: Gloriosa superba, Sansevieria trifasciata, Aloe vera, Cordyline terminalis, Pleomele angustifolia, and Allium fistulosum. Stomatal density, type, and distribution were measured to understand their relationship with leaf morphology. The results show that Gloriosa superba has a stomatal density of 148.72/mm² and an index of 0.295, with thin leaves. Sansevieria trifasciata, with its thick, fleshy leaves, has a lower stomatal density of 15.39/mm² and an index of 0.031. Aloe vera, another species with thick leaves, has a stomatal density of 38.47/mm² and an index of 0.067. In contrast, Cordyline terminalis and *Pleomele angustifolia, which have thin leaves, exhibit higher stomatal densities of 192.31/mm² and 128.21/mm², respectively. Their stomatal indices are 0.092 for Cordyline terminalis and 0.163 for Pleomele angustifolia. Allium fistulosum also has thin leaves, with a stomatal density of 100/mm² and a high stomatal index of 0.390. The study reveals that species with thicker leaves tend to have lower stomatal densities, a feature that helps reduce water loss in arid environments. These findings contribute to a deeper understanding of plant adaptation mechanisms and have implications for improving water-use efficiency in agriculture and conservation efforts.

Abstract

Rice-washed water is wastewater resulted from the rice cleaning process that is rich in nutrients. The use of ramie chip waste can be considered a potential substrate due to its lignocellulosic nature, similar to other wastes studied. This study aimed to examine the effect of rice-washed water on the mycelium and pinhead growth of white oyster mushrooms grown in the ramie chip waste as the growing medium. The experiment was conducted for three months using a completely randomized design with four rice-washed water treatments and six replications. The rice-washed water concentration treatments were 0% (K0), 25% (K1), 50% (K2), and 100% (K3), which were added to the ramie chip waste as the growing medium for white oyster mushroom. The time of mycelium propagation velocity, the time the first pinhead appearance, the number of mushroom bodies, and the largest cap diameter were observed. The results showed that ramie chip waste-derived media was suitable to cultivate white oyster mushrooms. Adding 100% rice-washed water to the media significantly affected the speed of mycelium propagation (16.51 days) compared to control (30 days) and the appearance of the first pinhead (31.5 days) compared to control (38.5 days) as well as the number of fruiting bodies of mushroom (8.8) compared to control (6.2). However, the rice-washed water application did not significantly affect the diameter of the largest mushroom cap.

Abstract

Eco-enzymes are a natural alternative to harmful synthetic chemicals in the home. Changing organic kitchen waste from vegetable and fruit waste into household and environmental recycling materials can help solve the waste problem. Eco-enzyme liquid has many uses, such as washing dishes, clothes, floors, hair, body wash, hand sanitizer, body detox, air freshener, radiation blocker, pool cleaner, pet and organic fertilizers and pesticides that can be made from organic waste. This community service program aimed to increase public awareness and sensitivity to the problems that were found in the environment, provide ideas for entrepreneurship such as the utilization of waste in the form of eco enzymes, and eco brick. The socialization activities were carried out through presentations, discussions, and demonstrations of making eco enzymes, as well as distributing questionnaires to find out the increase in the level of public understanding before and after the activity was carried out. The questionnaire results showed that people's knowledge about the use of organic waste to make eco enzymes increased after participating in extension activities, as well as the community's interest in processing organic waste into eco enzymes and using them in daily life

Abstract

Bidens pilosa is a plant known for its secondary metabolites with therapeutic properties. This study aimed to examine the effects of different light intensities on the morphology, anatomy, chlorophyll content, and secondary metabolite production of B. pilosa in the Arboretum of Universitas Padjadjaran. The shaded and unshaded area had light intensities of 5828 and 32768 lux, respectively. Leaf samples were collected from three different individuals in each area, with three leaves taken per plant. Morphological and anatomical traits such as leaf thickness, leaf area, stomatal density, and chlorophyll content were observed, along with secondary metabolite content. Results showed that plants in the shaded area had thinner leaves (0,19 mm) and lower stomatal density (275,16 cells/mm2) but a larger leaf area (4 cm2) and higher chlorophyll content (29,33 CCI) compared to leaves in the unshaded area, which had thicker leaves (0,213 mm), higher stomatal density (310,83 cells/mm2), a smaller leaf area (2,33 cm2), and lower chlorophyll content (27,27 CCI). Alkaloids, flavonoids, tannins, and saponins were detected in both conditions, with a higher level of alkaloid and tannin in unshaded plants. These findings enhance our understanding of the relationship between light intensity influences plant morphology, photosynthesis, and secondary metabolite production, with potential applications in cultivation and medicinal use.

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

Former gold mining land, especially those abandoned without reclamation, experiences serious physical, chemical, and biological degradation, and is potentially contaminated with heavy metals such as mercury (Hg). This study aims to evaluate the effectiveness of organic farming-based bioreclamation and good soil management, using dwarf elephant grass (Pennisetum purpureum) and chicken manure in improving the condition of former gold mining land. The parameters analyzed include physical, chemical, and biological properties of the soil, as well as mercury levels in the soil and plants. The results showed that the soil quality index increased from 0.32 (low) to 0.62 (good). The organic C content increased from 0.91% to 2.16%, soil pH increased from 3.53 to 5.03, and the availability of phosphorus and potassium also increased. The population of methyl mercury-reducing bacteria increased 22.4 - 58.2 times, indicating improved microbial adaptation to the environment. Mercury content in plant tissue decreased drastically from 11.60 mg/kg to 0.11 mg/kg or a decrease of 99.05%, although still slightly exceeding the threshold. The conclusion is that reclamation with an organic approach and effective soil management not only improves soil fertility and quality, but also reduces the risk of heavy metal poisoning.

Abstract

The background of this study is that 11 of the 15 children in Group B at Permata Bunda Preschool have not yet developed patience. An educator must have the desire and ability to teach their students to be good children and be able to change bad traits into good ones. Therefore, the purpose of this study is to increase patience in children at Permata Bunda Preschool. The learning method used to increase children's patience is the Play, Story, and Singing method. Through the Play, Story, and Singing method, the researcher used a Classroom Action Research design, with two cycles of action. The level of children's patience in the initial observation was only 49.25%. Then, actions were taken in cycle I, and the children's patience increased to 64.25%. However, this value did not reach optimal results, therefore, actions were carried out again in cycle II to improve patience. In this study, the researcher used the Classroom Action Research method through two cycles. The results of activities in cycle II showed optimal results of 92%. The results obtained after the second cycle of action indicate that the application of the Play, Story, and Singing method to foster patience in children at Permata Bunda Preschool (PAUD) resulted in optimal improvement and can be reused by teachers as a learning method in the future.
