Abstract

Pitcher plants are plant species that have unique shapes. Nepenthes spp. in the feature has become an important issue about his developments in research on carnivorous plants and rare plants. Nepenthes spp. has been classified as a protected plant due to excessive exploitation, which can damage the place of origin. The research in this article focuses on analyzing the content of chlorophyll a, b, and carotenoid in leaves and pitchers of Nepenthes gracilis. Leaves and pitchers (fresh and dried) were extracted in 3 types of solvents (acetone, methanol, and DMSO). The samples were then analyzed with a UV-VIS spectrophotometer. The results showed that the leaf and pitcher samples had quite different results. The leaf sample showed higher results than the pitcher sample, which had a chlorophyll a (3.434a), chlorophyll b (1.311a), carotenoids (0.918a), and total chlorophyll (4.745a) content. The pitcher sample had a content of chlorophyll a (1.463b), b (0.642b), carotenoids (0.445b), and total chlorophyll (2.105b). The treatment of samples given various solvents such as DMSO, Acetone, and Ethanol showed insignificant results on the content of chlorophyll a, chlorophyll b, carotenoids, and total chlorophyll. The conclusion is that all solvents can be used to analyze pigment content. Keywords: Carnivorous plant, Nepenthes gracilis, Pigment Content, Extracted solvents

Abstract

Abstract – SD Negeri 12 Padang Panjang is one of the schools that has made efforts to implement the Adiwiyata program. In 2024, the school represented the city of Padang Panjang in the Adiwiyata competition at the West Sumatra provincial level; however, it did not achieve optimal results. For the 2025 Adiwiyata program, SD Negeri 12 has set a target to become the provincial representative of West Sumatra. Based on the evaluation results from 2024, it was found that the assessment indicator for Participatory-Based Environmental Activities needs improvement. One activity that can support this effort is hydroponic cultivation. A hydroponic cultivation training was conducted by 26 fifth-grade students. The training included both theoretical material and hands-on practice in cultivating green vegetables using a hydroponic system. The training was guided by two experts who are competent in the field. This training successfully increased students' knowledge of hydroponic vegetable cultivation. Moreover, over 90% of the participants demonstrated teamwork and developed a greater awareness of environmental care. This outcome is a significant contribution to supporting SD Negeri 12 Padang Panjang Barat’s efforts toward achieving Adiwiyata School status.

Abstract

The production of manganase peroxidase (MnP, a key lignolityc enzyme with broad applications in bioremediation and industrial processing, can be significantly enhanced trough the optimation of medium composition and fermentation time. This study aimed to determine the optimal organic medium, concentration, and incubation period for MnP production by Pleurotus ostreatus. Various plant-base substrates such as brown rice, mungbean, almond, red bean soybean, and potato dextrose broth (PDB) were evaluated using a descriptive method, withvthe obtained data calculated and analyzed in Excel, and the results presented in the form of diagrams. The results showed that brown rice medium is the most optimal medium to support the produvction of MnP (981,6 U/L), attribute to its high carbohydrate and micronutrien content. Futher optimization revealed that a consentration of 7,5%, while fermentation time optimization indicated that the 9th day was optima, producing up to 3207,1 U/L of enzyme activity. These findings suggest that selecting the right substrate and fermentation conditions can substantially improve MnP synthesis by P. ostreatus, making it a promising strategy for sustainable enzyme production and future biotecnological application. For future studies, it is recommended to explore large scale fermentation systems and alternative agro industrial waste susbtrates to further enhance enzyme yield and cost efficiency

Abstract

The rapid advancement of technology and information has led to a significant increase in smartphone usage in Indonesia, reaching 67.88% in 2022. Smartphones emit non-ionizing electromagnetic waves that may pose biological effects, particularly on the kidneys, which play a crucial role in maintaining the body's homeostasis. Previous studies have reported that electromagnetic radiation can induce histological damage in the kidneys through oxidative stress mechanisms, including tubular narrowing, Bowman’s capsule dilation, and tubular epithelial necrosis. Airplane mode is known to significantly reduce electromagnetic radiation exposure. This study aimed to determine the effect of smartphone radiation in airplane mode on the kidney histology of female mice. An experimental design was employed using four female mice divided into one control group and three treatment groups, which were exposed to a smartphone in airplane mode for 4, 6, and 8 hours per day for 7 consecutive days. Kidney tissues were processed using paraffin embedding and stained with Hematoxylin–Eosin for microscopic examination. The results showed no significant histological differences between the control and treatment groups. The glomerulus, Bowman’s capsule space, and proximal and distal convoluted tubules appeared normal without signs of narrowing, dilation, hemorrhage, or necrosis. These findings indicate that smartphone radiation in airplane mode does not cause histological damage to the kidneys of female mice.

Abstract

Biofuels are fuels derived from biomass and consist of biogas, biodiesel and bioethanol. Bioethanol is a biofuel whose main ingredients are from plants and generally use microorganisms in the fermentation process. One way is to use thermophilic bacteria with the advantage of low contamination levels and better product quality. Bacteria that exist in nature are not only in a single form but also exist in the form of a consortium in which there are beneficial or detrimental bacterial interactions. Favorable bacterial interactions indicate that the bacteria are compatible. Using a consortium with compatible bacteria gives better results than using a single bacteria. This study aims to determine the compatibility and effect of a consortium of thermophilic bacteria from Mudiak Sapan hot springs on biofuel yields. This research is a descriptive research. To test the cooperation between isolates, a compatibility test was carried out using the disk diffusion method. Then the biculture consortium isolates of thermophilic bacteria were fermented in liquid TMM medium (Thermophilic Minimum Media) and the bioethanol content was measured using a distillation apparatus. The results of this study showed that the six pairs of compatible consortium and MS 9-12 consortium produced the highest bioethanol, namely 1.0003%. Then the biculture consortium isolates of thermophilic bacteria were fermented in liquid TMM medium (Thermophilic Minimum Media) and the bioethanol content was measured using a distillation apparatus. The results of this study showed that the six pairs of compatible consortium and MS 9-12 consortium produced the highest bioethanol, namely 1.0003%. Then the biculture consortium isolates of thermophilic bacteria were fermented in liquid TMM medium (Thermophilic Minimum Media) and the bioethanol content was measured using a distillation apparatus. The results of this study showed that the six pairs of compatible consortium and MS 9-12 consortium produced the highest bioethanol, namely 1.0003%.
