Get PDFThis study aimed to evaluate the growth and yield responses of soybean (Glycine max L. Merr.) to the application of liquid organic fertilizer (LOF) derived from apu-apu (Pistia stratiotes L.) and various soil conditioners on Ultisol soil. The research was carried out from September to December 2020 at the experimental garden of the Faculty of Agriculture, Universitas Medan Area, located at an altitude of 22 masl with flat topography, Ultisol soil characteristics, and a soil pH of 4.94. The experimens used a randomized block design with two factors: (1) concensrations of apu-apu LOF (0%, 25%, 50%, and 75% per liter of water) and (2) types of soil conditioners (no conditioner, rice-husk biochar, Mucuna bracteata green manure, and human-hair organic amendmens at 50 g per polybag). Observed parameters included plans height, number of branches, flowering age, number of bunches per plans and per plot, number of pods per plans and per plot, seed weight per plans and per plot, and 100-seed dry weight. The results showed that the application of LOF from apu-apu significansly increased several agronomic and yield componenss, namely number of branches at 6 WAP, number of bunches per plans and per plot, number of pods per plans and per plot, seed weight per plans and per plot, and 100-seed dry weight. Meanwhile, the application of differens soil conditioners produced highly significans effects on plans height at 4–6 WAP, number of pods per plant and per plot, seed weight per plans and per plot, and 100-seed dry weight, although it did not significansly affect the number of branches or number of bunches. Overall, the combination of LOF and soil conditioners improved soybean growth and productivity in Ultisol soil conditions

Immunomodulatory Activity of Chinese Betel (Peperomia pellucida L.) Extract on the Spleen Histopathology in a Murine Model of Gastroenteritis
Get PDFGastroenteritis, a prevalent digestive disorder caused by various pathogens including Escherichia coli, remains a global health challenge with significant morbidity and mortality, particularly in low-income countries. The spleen, as a critical immune organ, is often compromised during systemic infections. Peperomia pellucida (L.) , a traditional medicinal herb, is known for its antimicrobial, anti-inflammatory, and antioxidant properties. This study investigates the histopathological effects of P. pellucida leaf ethanol extract on spleen tissue in mice induced with E. coli to model bacterial gastroenteritis. Thirty male Swiss mice were divided into six groups (n=5): normal control, negative control (aquades), positive control (Yakult), and three treatment groups receiving P. pellucida extract at 100, 300, and 500 mg/kg BW. After seven days of pretreatment, mice were orally infected with E. coli (1×10ⶠCFU/mL) for another seven days. Spleen tissues were harvested, fixed, and stained with hematoxylin-eosin for histopathological evaluation focusing on degeneration, necrosis, and PMN infiltration. Statistical analysis was performed using ANOVA followed by LSD tests. The highest dose of P. pellucida extract (500 mg/kg BW) significantly reduced spleen tissue damage, showing decreased degeneration (9.08%), necrosis (6.05%), and PMN infiltration (18.45%) compared to lower doses. The effect was comparable to the positive control. The ethanol extract of P. pellucida demonstrates a dose-dependent protective effect on spleen histopathology in E. coli-induced gastroenteritis in mice, supporting its potential as a natural antiseptic agent
The Impact of Social Media Addiction on Adolescent Mental Health in Ambon City, Indonesia
Get PDFThe increasing prevalence of social media use among adolescents has raised concerns regarding its potential impact on mental health. This study investigated the relationship between social media addiction and adolescent mental health in Ambon, Indonesia. A quantitative cross-sectional research design was utilized, involving 336 adolescents aged 13-18 who actively used social media. Data were gathered through a structured questionnaire assessing demographic characteristics, social media usage patterns, and mental health status using the Depression Anxiety Stress Scale (DASS-21). Descriptive analysis, bivariate analysis using odds ratios (ORs), and multivariate analysis via multiple logistic regression were conducted. Results indicated that 64.88% of respondents had poor mental health scores. Bivariate analysis revealed significant associations between age, study frequency, duration of social media use, and social media usage scores with mental health conditions (p<0.05). Multiple logistic regression identified that adolescents aged 18-20 years, those who studied infrequently, used social media for over three hours daily, and had high social media usage scores were at greater risk of poor mental health. These findings underscore the importance of collaborative efforts among stakeholders to design effective interventions and policies that foster responsible social media use and promote adolescent mental well-being in the digital era
Detection of Escherichia coli Contamination Using Most Probable Number (MPN) Methods of Jamu Pahitan in Singaparna District, Tasikmalaya
Get PDFIndonesians consume a lot of traditional jamu, including jamu pahitan. However, the hygiene aspect in the production and serving process is often neglected, so it has the potential to be contaminated with Escherichia coli. Using the MPN method, this study analyzed the presence of E. coli in jamu pahitan sold in Singaparna District. A total of 10 samples were tested, taken from jamu vendors who used plastic bottle packaging. The MPN test results showed that all samples contained E. coli with MPN values ranging from 6.0-1100 g/mL. None of the samples met food safety standards based on SNI 7388:2009, because the maximum limit of E. coli in drinks is <3 MPN/mL. The results of Gram staining of bacteria showed that the bacteria found were bacilli, red in color, including Gram-negative bacteria, indicating the presence of E. coli bacteria

The roots of A. cepa from the soaking treatment of C. latifolia extract were used to make preparations using the squash method. The results of the ANOVA test showed that the administration of C. latifolia root extract had a significant effect on the mitotic index and cell abnormalities (P<0.05). P1 had the most effective value in reducing the mitotic index and cell chromosome abnormalities
Effectiveness of Cherry Tomato Extract in Gel Form to Accelerate the Healing Process of Excision Wounds in Wistar White Rats
Get PDFCherry tomatoes (Solanum lycopersicum L. var. cerasiforme) are rich in antioxidants, particularly flavonoids and lycopene, which help reduce free radicals and promote wound healing. Flavonoids exhibit anti-inflammatory, antioxidant, antibacterial, and antidiabetic properties. They enhance wound contraction, collagen deposition, granulation tissue formation, and epithelialization in wound healing. This study evaluates the efficacy of cherry tomato extract gel in accelerating excision wound healing in Wistar rats. This in vivo experimental study used a post-test control group design. Twenty-five 2–3-month-old Wistar rats with excision wounds were treated with cherry tomato extract gel or controls. The five groups included a positive control (NaCl), a negative control (CMC-Na gel), and treatment groups receiving 8%, 12%, or 16% extract gel. Wound size was measured on days 3, 5, 7, and 9, with data analyzed using One-Way ANOVA and post hoc tests. The extract-treated groups exhibited nearly complete wound closure by day 9. The wound size of the treatment groups significantly differed from the control groups (p<0.05). Cherry tomato extract gel significantly accelerates wound closure at 8%, 12%, and 16% concentrations, with the best results observed at 16% (p<0.05), surpassing even the positive control. The 16% extract gel group demonstrated the most effective wound healing. Cherry tomato extract gel significantly enhances wound healing, with the 16% concentration demonstrating the most effective acceleration of wound closure. These findings suggest that cherry tomato extract gel, particularly at 16%, holds promise as a potent wound-healing agent

The Effect of Angkak Addition Towards DPPH Antioxidant Activity and Yields in Mixed Angkak-Red Ginger Extracts
Get PDFAngkak and red ginger, which represents West Borneo’s Chinese ethnic group’s herbal cooking, were studied to produce antioxidant activity through shogaol along with monacolin K and respond to DPPH (2, 2-diphenyl-1-picrylhydrazyl) test. This research aims to combine the two ingredients into extracts and observe how they affect the yields and IC50 value. Methods were started with the extraction of both materials in a variety of simplicia powder weights using 800 rpm stirring speed at 60°C for 120 minutes. The extracts were then tested for percentage yield (%), Thin Layer Chromatography (TLC), and half-maximal inhibitory concentration (IC50) value. IBM SPSS Statistics 25 analysis was also carried out at the end for yields and IC50 values data. Results showed that the angkak addition affected the IC50 value without giving any significant impact on each yield amount (p-value>0,05). Increased angkak in the variations led to the IC50 values decrease, ranging from 122.996 ppm (Mix 1) to 225.399 ppm (Mix 3). Angkak’s pigments and red ginger’s polyphenol compounds which provide antioxidant ability were found to occupy Mix extracts based on the TLC profile. In conclusion, angkak decreased the DPPH antioxidant activity of its extract combination with red ginger, but did not affect the yield percentage
