The study used a pseudo-experimental design with a posttest-only control group design pattern. The population included the entire class VII, and the sample was randomly selected of two equivalent parallel classes, totaling 22 students each. The experimental class received the discovery learning treatment, while the control class used conventional methods. The research instrument is in the form of learning outcome tests in the form of objectives and essays that have been tested for validity and reliability. Data were analyzed through normality test, homogeneity test, and t-test of two independent samples at a significance level of 0.05. The results showed significant differences between the two groups. The average posttest score of the experimental class was 80.68 higher than the control class of 72.72. The analysis of the t-test yielded a t_hitung value of 2.74 greater than t_tabel 2.01, which means that the null hypothesis was rejected. The frequency distribution in the experimental class also showed a concentration of scores in the high category, while the control class was more dominant in the medium category. These findings confirm that discovery learning not only improves cognitive learning outcomes, but also encourages students' active engagement, motivation, and critical thinking skills. This study concludes that the implementation of discovery learning is effective in improving science learning outcomes in the classification of living things. Implicitly, teachers are advised to integrate this approach as an alternative to student-centered science learning strategies.

Fungal infections are a common health problem in tropical regions, including Indonesia, since humid conditions support microbial growth. Candida tropicalis is a pathogenic species frequently identified as the cause of both superficial and systemic candidiasis. The rising resistance to synthetic antifungal agents such as fluconazole and ketoconazole highlights the need for safer and more effective alternative therapies. Propolis, a resinous substance produced by Trigona sp. bees from various plant sources, contains flavonoids, phenolics, and terpenoids with important biological activities, including antimicrobial and antifungal effects. This study aimed to evaluate the effectiveness of ethanol extract of propolis from Balikpapan against the growth of Candida tropicalis using the disk diffusion method. Phytochemical screening revealed the presence of alkaloids, flavonoids, phenolics, tannins, and terpenoids in the extract. Antifungal activity testing showed that concentrations of 80%, 90%, and 100% significantly inhibited fungal growth, with the largest inhibition zone of 27.93 mm observed at 100% concentration. Statistical analysis using ANOVA confirmed significant differences among treatments. Thus, ethanol extract of Trigona sp. propolis from Balikpapan demonstrates strong potential as a natural antifungal agent. These findings support the use of propolis as a natural-based therapeutic alternative for fungal infections and contribute to the development of herbal pharmaceutical products.

Burn injuries are a significant health problem because they damage the skin’s protective barrier, increase the risk of infection, and may cause severe complications if not treated properly. The healing process is complex and involves several cellular events, in which fibroblasts play a key role by producing collagen and forming granulation tissue. Recently, there has been growing interest in natural, herbal-based therapies for wound care. Tamarind leaves (Tamarindus indica) were chosen in this study because they contain flavonoids, polyphenols, tannins, and saponins, all of which have anti-inflammatory, antioxidant, and tissue-regenerating properties. The aim was to evaluate the effectiveness of ethanol extract gel of tamarind leaves at concentrations of 2.5%, 5%, and 10% in promoting fibroblast proliferation and healing of burn wounds in male rats (Rattus norvegicus). An experimental randomized design was used with six groups: normal control, neative control, positive control, and three treatment groups. Clinical observation and histopathological analysis showed that the extract gel accelerated wound closure significantly compared to the negative control. Fibroblast proliferation was higher in all treatment groups, with the 10% extract giving the best result, similar to Bioplacenton. These findings highlight tamarind leaves’ potential as a safe and affordable alternative for burn wound therapy.

The prevalence of social media addiction is continuously increasing worldwide, including in Indonesia. Instagram has become the most widely used platform among students aged 18–25 years. Although Instagram provides many benefits, spending too much time on the application can cause learning concentration problems, procrastination, and a decrease in Grade Point Average (GPA). The purpose of this study was to determine whether there is a correlation between Instagram social media addiction and GPA among students of the Diploma Three Nursing Program at Universitas Abulyatama. This study applied a cross-sectional quantitative correlational design. The sampling technique used proportional random sampling, involving 78 students from a total population of 362 students. The research instruments consisted of cumulative GPA data and The Instagram Addiction Scale (TIAS). The study was conducted at the Diploma Three Nursing Program of Universitas Abulyatama from April 26 to May 9, 2025. Data analysis was performed using bivariate analysis with the Chi-Square test. The results showed that the majority of respondents were in the moderate category of Instagram addiction (56 students, 71.8%), followed by the high category (22 students, 28.2%). Meanwhile, GPA distribution indicated that 35 students (44.9%) were in the very high category, 24 students (30.8%) in the high category, and 19 students (24.3%) in the moderate category. The bivariate analysis with the Chi-Square test obtained a p-value of 0.001 (≤ 0.05), indicating a significant relationship between Instagram addiction and GPA. In conclusion, there is a correlation between Instagram social media addiction and students’ academic performance. Although Instagram use is widespread, students are expected to develop good time management skills and prioritize academic responsibilities to minimize the negative impact of social media use.

Organic agriculture plays a vital role in Indonesia’s agricultural development, with a key challenge being how to boost productivity efficiently and sustainably. Liquid Organic Fertilizer (LOF) derived from natural materials provides an eco-friendly option to improve soil fertility and crop yields. Bamboo shoots (Bambusa spp.), rich in organic carbon and gibberellin, present strong potential as LOF raw material to support plant growth. This study evaluated the effect of bamboo shoot-based LOF on the growth and yield of white radish (Raphanus sativus). The research was conducted from May to August 2025 in Kalolok, Batupapan Village, Tana Toraja Regency, South Sulawesi, at an altitude of 775 m. LOF was produced by fermenting 200 kg of ground bamboo shoots with 4 kg palm sugar, 1 liter EM4, and 200 liters water for 14 days. Treatments consisted of 0, 100, 200, and 300 ml per liter of water, applied twice at two-week intervals starting 14 days after planting. Using a randomized block design with four treatments and three replications, variables observed included plant height, leaf number, tuber size, and yield. Results showed that 300 ml/liter LOF gave the best outcomes: tallest plants (27 cm), most leaves (15.89), largest tubers (29.37 cm length; 6.06 cm diameter), and highest weight (731 g/plant; 6936.67 g/plot). These effects are linked to balanced nutrients (N, P, K, Mg, Ca) enhancing vegetative growth and tuber development. Thus, bamboo shoot-based LOF at 300 ml/liter is recommended as an effective organic fertilizer for white radish.

Background: Anemia is one of the public health problems commonly found among adolescent girls, especially in developing countries like Indonesia. This condition affects concentration, academic performance, and productivity, making early detection an essential step to prevent long-term complications. Objective: This study aims to determine the results of early detection of anemia based on clinical symptoms and hemoglobin (Hb) levels among adolescent girls at SMPN 18 Palembang. Methods: This research used a descriptive design with a cross-sectional approach. A total of 132 seventh-grade female students were selected randomly. Data were collected through an anemia symptom questionnaire and hemoglobin level measurement using a hemoglobinometer. Results: The study found that 23.5% of respondents were anemic (Hb < 12 g/dL), and 48.5% showed symptoms of anemia. However, the sensitivity of symptoms in detecting anemia was only 39%, specificity was 19%, with a positive predictive value (PPV) of 60.93% and a negative predictive value (NPV) of 8.82%. Conclusion: Based on the findings, symptom-based detection alone is not sufficiently accurate to diagnose anemia. Hemoglobin level examination is still required as a more valid and objective screening method for the early detection of anemia in adolescent girls In addition to medical intervention, the study advocates for increased awareness and education about anemia, its causes, and prevention methods among students, parents, and educators. Addressing nutritional deficiencies, especially iron intake, through dietary improvements and supplementation is essential in combating anemia in adolescent girls.

Colitis is an inflammatory characterized by thickening of the mucosal wall of the colon. The Colon In Loop examination is one of the diagnostic procedures for colitis, utilizing contrast media to assess the functional condition of the colon. At the Radiology Installation of RSUD (Regional General Hospital) Banyumas, the radiological procedure for Colon In Loop was performed on post-colostomy patients, thus differs from previous studies. This study aims to identify the examination procedure of Colon In Loop at RSUD Banyumas, the rationale for using Anteroposterior (AP) and Lateral projections, and the reason for not performing evacuation before the administration of negative contrast media. This qualitative descriptive study employed a case. The subjects included three radiographers, one radiology nurse, and one radiology specialist. The object of study was the Colon In Loop Post Colostomy examination procedure in colitis cases. Data were collected through observation, interviews, documentation. Data analysis involved data reduction and data presentation. confirmed with theory, and narrative presentation leading to conclusions. Result shows contrast media consisting of 250 grams of barium sulfate dissolved in 1000 ml of water (25% w/v). The examination is performed in stages followed by AP and Lateral projection imaging to evaluate contrast distribution in the colon. Negative contrast media administration is performed without prior evacuation to enhance patient comfort and reduce examination time. When administering negative contrast media, evacuation is not performed before air is introduced. This is done based on the patient's condition, to shorten the examination time, and due to considerations regarding the quality of barium sulfate; thus, evacuation could impair barium adherence to the colon mucosa. In conclusion, AP and lateral projections are considered adequate for establishing a diagnosis of colitis. The omission of evacuation is based on patient condition, time efficiency, and the suboptimal quality of barium. It is recommended to perform evacuation and increase barium concentration to improve adherence to the colon mucosal wall.

This article examines the legal consequences of a delayed notification of a share acquisition under Indonesian competition law, focusing on the case of PT X's takeover of PT Y. The central issue is PT X's failure to report the acquisition to the Commission for the Supervision of Business Competition (KPPU) within the mandated 30-day period, as stipulated by Law Number 5 of 1999 and its implementing regulation, Government Regulation Number 57 of 2010. The notification was submitted with a significant delay of 2,023 days, a clear violation of the statutory requirements. As a result of this non-compliance, the KPPU, through its Decision No. 31/KPPU-M/2020, imposed an administrative fine on PT X amounting to   IDR 1,050,000,000.00 (one billion fifty million rupiah). Beyond the direct financial penalty, the violation led to severe indirect repercussions, including significant    reputational damage, which threatened to erode investor confidence and disrupt existing business relationships. The KPPU's firm and consistent enforcement in this case highlights the critical function of the post-merger notification system in Indonesia as a preventative mechanism to assess transactions that could lead to excessive market concentration. The decision underscores the legal principles of     transparency, fairness, and accountability that underpin Indonesian competition law. This case serves as a powerful deterrent, signaling to all business actors that non-compliance will not be tolerated. Ultimately, such rigorous enforcement is crucial for fostering a culture of legal adherence, maintaining market integrity, and building a more transparent and competitive business ecosystem that supports sustainable economic growth in Indonesia.

This study aims to analyze the influence of using non-digital or “traditional” learning media on the learning concentration of Grade X students in Islamic Religious Education (PAI). The background of this research is based on the phenomenon of increasing student distractions caused by the use of gadgets and digital media, which often reduce focus during the learning process. Therefore, alternative learning strategies are needed by utilizing simple media that emphasize direct interaction between teachers and students. The research method used is quantitative with a survey approach through questionnaires distributed to Grade X students as respondents. The study population consists of all Grade X students at one senior high school, with the sample determined using Slovin’s formula to ensure representativeness. Data were analyzed using simple regression techniques to measure the extent of the influence of non-digital learning media on students’ concentration levels in PAI learning. The results of the study show a positive and significant effect, where non-digital learning media such as blackboards, flashcards, and simple teaching aids were proven to help increase focus, reduce distractions, and strengthen comprehension of religious subject matter. In addition, the use of traditional media encourages active student participation through discussions and hands-on activities, making the learning process more interactive. Thus, this study concludes that non-digital learning media remain relevant as effective alternatives, particularly in PAI learning for Grade X students, and can serve as a practical solution in addressing the challenges of the digital era, which is filled with potential distractions.

Sappan wood (Caesalpinia sappan L.) is known to contain various bioactive compounds such as saponins, tannins, flavonoids, phenols, brazilin, and gallic acid. These compounds play an important role as antioxidants that can ward off free radicals and absorb UVA and UVB radiation that are harmful to the skin. Ultraviolet radiation is known to accelerate premature aging and cause tissue damage, so a topical formulation is needed that can provide protection while maintaining skin health. This study aims to determine the antioxidant activity and sunscreen ability of sappan wood extract in the form of lip balm with varying extract concentrations. Antioxidant activity was evaluated using the DPPH (1,1-Diphenyl-2-Picrylhydrazyl) method, while the Sun Protection Factor (SPF) value was determined by the Mansyur method using UV-Vis spectrophotometry. Sappan wood extract was formulated into four lip balm preparations, namely F0 (control without extract), F1 (5%), F2 (10%), and F3 (15%). Physical tests including homogeneity, pH, spreadability, adhesiveness, and organoleptic were conducted to ensure the quality of the preparation. The results showed that sappanwood extract had an IC50 value of 23.62 ppm which was categorized as very strong antioxidant activity. In the lip balm formulation, the IC50 values ​​obtained were F0 = 246.76 ppm (very weak), F1 = 92.68 ppm (strong), F2 = 78.03 ppm (strong), and F3 = 63.58 ppm (strong). The SPF test showed a protection value of F0 = 2.11 (minimum), F1 = 13.64 (maximum), F2 = 14.25 (maximum), and F3 = 18.28 (ultra). Thus, lip balm made from sappanwood extract has the potential as a cosmetic preparation that not only meets physical criteria, but also provides high antioxidant activity and effective sunscreen protection.

Anemia is a global health problem affecting approximately 30% of adolescents worldwide, with the highest prevalence among women aged 15-49. In Indonesia, data from the Ministry of Health in 2019 showed that the prevalence of anemia in adolescent girls reached 32%, with cases higher than in adolescent boys (27.2% vs. 20.3%). Anemia in adolescent girls negatively impacts growth, increases susceptibility to infection, and affects concentration and academic performance.

These results indicate that consuming pandan leaf pudding is effective in increasing hemoglobin levels in the study group.

This study was motivated by the low performance of students’ drop shot skills in elementary school badminton extracurricular activities, where the success rate of shots remained low despite regular training. The aim of this research was to analyze the effect of drop shot training using two methods—fixed targets and variable targets—on improving students’ shot accuracy. The study employed an experimental method with a pretest-posttest control group design. The sample consisted of 30 students selected through purposive sampling, with the requirement of having participated in badminton extracurricular activities for at least one year. The participants were divided into two groups: 15 students underwent fixed-target training, and 15 students underwent variable-target training. The training program was implemented over six weeks with a frequency of three sessions per week. The results indicated that both training methods significantly improved students’ drop shot accuracy. However, the variable-target training group showed greater improvement compared to the fixed-target group. This was due to the training variation, which required better concentration, adaptability, and decision-making, making it more similar to real game conditions. These findings highlight the importance of applying varied training methods in developing students’ basic badminton skills. Therefore, this study provides practical implications for coaches to prioritize variable-target training methods in coaching programs to enhance the effectiveness of technical skills, particularly the drop shot.
