Abstract

Light intensity in plants influences their growth potential as well as their morphological, anatomical, and physiological structures. This study aimed to observe the leaf area, leaf thickness, leaf type, stomatal type, stomatal density, chlorophyll content, and phytochemical content of Sente leaves (Alocasia macrorrhizos) in two locations with different light intensities. This exploratory research used a survey method to determine the research location, and environmental parameter measurements was used as supporting data. Morphological and anatomical parameters and chlorophyll content were assessed using a quantitative approach, while phytochemical content was determined qualitatively and analyzed descriptively. The results showed differences in the morphology, anatomy, chlorophyll content, and phytochemicals of Sente leaves in varying light intensities. Morphologically, the leaves of Sente plants in shaded locations had larger surface areas, were thinner, and appeared greener compared to those in unshaded locations. The stomatal density of leaves in unshaded areas was higher (76.43 cells/mm ²) compared to shaded areas (56.05 cells/mm ²). The chlorophyll content in shaded locations was higher (82.03 CCl) than in unshaded locations (41.7 CCl). Phytochemical tests for flavonoids and saponins showed higher compound levels in leaves from unshaded locations, while tannin tests revealed higher levels in shaded locations compared to unshaded ones. Meanwhile, tests for alkaloids and quinones yielded negative results.

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

This research aimed to obtain the optimal concentration combination of 2,4-D and BAP growth regulators for inducing callus from the stem explant of Chrysanthemum (C. morifolium Ramat) in bright and dark conditions. Stem explants of chrysanthemum were grown in culture medium supplemented with various concentrations and combinations of 2,4-D and BAP under different lighting conditions for 45 days after culture. A laboratory-scale experimental method was used in this research using Completely Randomized Design (CRD). The observed parameters were induction time, percentage formation, size, fresh weight, dry weight, texture, color, and various respones generated by callus. All data were analyzed descriptively. The results showed that all concentrations and combinations of growth regulators could induce callus. In bright condition, the fastest callus induction time was 7 days after culture; most calli were dark green and dark brown colored with compact texture; the callus size was 1.36 cm; also, the highest dry weight generated by callus was 0.17 gram. Meanwhile, in dark conditions, the fastest callus induction time was 6 days after culture; most calli were light green and light brown colored with compact texture; the callus size was 1.18 cm; and the highest dry weight generated by callus was 0.15 gram.

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

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.

Abstract

Neonatal jaundice is the condition of a newborn with high levels of bilirubin, which can cause various negative impacts on the baby, such as neurological abnormalities, mental retardation and seizures. The main treatment that can be done is by administering light phototherapy. Preliminary studies in the city of Bandung, there are still hospitals in Bandung that use phototherapy with the Compact Flourescent Lamp (CFL) type of lamp and there are also hospitals that use phototherapy with the Light Emitting Diode (LED) type. Objective: The aim of this research is to identify the effectiveness of LED and CFL phototherapy in reducing bilirubin levels in babies with neonatal jaundice in Bandung City. Method: This research method is a quasi-experiment with a retrospective approach. The sample for this study was 72 babies who were given phototherapy from January to July 2023. The data collection technique used data recorded at hospitals in Bandung City. Data was collected with checklist sheets and data analysis using the independent sample t test. The research locations were Bandung Kiwari Hospital and Bandung Muhamadiyah Hospital. Results: The results of the independent t-test showed a significant difference in total serum bilirubin values in the two groups before and after phototherapy (sig coefficient = 0.000 < 0.05). The group of neonates with CFL had a bilirubin value of 9.3989 which was higher compared to the group of neonates with LED phototherapy, namely 6.4189. LED phototherapy is more effective in reducing bilirubin compared to CFL phototherapy. Conclusions: Hospital policies to add LED phototherapy facilities can be considered, because they are more effective in reducing bilirubin levels.
