Hydroponic cultivation of mustard greens (Brassica juncea L.) in greenhouses is an effective alternative for overcoming land limitations, particularly in urban areas. Hydroponic systems enable plants to obtain nutrients optimally through the application of the Nutrient Film Technique (NFT) and Deep Flow Technique (DFT), thereby promoting more efficient plant growth. In addition, the success of hydroponic mustard cultivation is influenced by environmental control, including temperatures ranging from 15–35°C and relative humidity levels of 70–90%. Plant nutrient requirements are supplied through an AB Mix nutrient solution with a pH range of 5.5–6.5 and an electrical conductivity (EC) value of 1.5–3.0 mS/cm. This review aims to analyze various factors affecting the growth of hydroponic mustard greens, including nutrient management, environmental conditions, and biological pest and disease control using beneficial agents such as Trichoderma and Bacillus. Furthermore, this study discusses several technical and economic challenges that may influence cultivation success. The findings indicate that hydroponic systems can significantly improve crop productivity and yield quality, reduce the use of chemical pesticides, and support the implementation of sustainable and environmentally friendly urban agriculture in Indonesia.

Food safety of fresh fish is an important concern because fish is highly perishable and may be misused with hazardous preservatives such as formalin. This study aimed to determine formalin content and analyze the relationship between length and weight of Nile tilapia (Oreochromis niloticus) and formalin levels in traditional markets of Gorontalo City. The study was conducted from January to February 2026 in five traditional markets, namely TPI Tenda, Moodu, Potanga, Andalas, and Sentral. Nile tilapia samples were analyzed using a formaldehyde test kit, and formalin levels were expressed in ppm. Total length and fish weight were measured, and the relationship between physical size and formalin content was analyzed using Pearson correlation. The results showed that all Nile tilapia samples tested positive for formalin, with concentrations ranging from 0.11 to 0.23 ppm. The highest formalin levels were found in TPI Tenda and Moodu, each at 0.23 ppm, while the lowest level was found in Sentral at 0.11 ppm. Fish length ranged from 19.43 to 25.61 cm, while fish weight ranged from 0.17 to 1.78 g. The correlations between length and formalin content and between weight and formalin content were both very strongly negative, with r = -0.97. These findings indicate that smaller fish tended to contain higher formalin levels. Market supervision, trader education, and formalin-free fish handling practices should be strengthened to protect consumer health.

Reproductive health is an aspect of health that still requires serious attention, particularly for women of reproductive age. Polycystic Ovary Syndrome (PCOS) is a hormonal disorder with a prevalence of 3.4% among women worldwide, yet it often goes undetected due to a lack of awareness. This community service activity aims to increase the knowledge of women of reproductive age regarding menstruation, PCOS, and the importance of early detection through an educational webinar titled “Hormone Talk: Exploring Menstruation, PCOS, and the Importance of Early Detection.” The event was held online via the Zoom Meeting platform on December 13, 2025, and was attended by over 100 participants, the majority of whom were female students. The evaluation method utilized pre-tests and post-tests analyzed using a Dependent T-test. The results showed a significant increase in the average knowledge score from 64.78 (pre-test) to 79.67 (post-test), with a difference of 14.89 points and a p-value of 0.000. This demonstrates that reproductive health educational webinars are effective in enhancing participants’ knowledge. It is hoped that this activity can serve as a model for sustainable digital-based health promotion interventions in efforts to improve reproductive health literacy among Indonesian women.

Soybean is an important food commodity in Indonesia because it is the main raw material for tofu and tempeh, two major protein sources widely consumed by the population. However, domestic soybean production remains far below national demand resulting in heavy dependence on imports. In contrast maize is increasingly preferred by farmers due to its higher productivity and a more stable economic value. Therefore, maize–soybean intercropping has emerged as a promising strategy to improve land-use efficiency while increasing soybean production without reducing maize cultivation. This study systematically mapped and synthesized maize–soybean intercropping research in Indonesia and conducted a meta-analysis of Land Equivalent Ratio LER values reported across studies. Literature searches using Scopus, Web of Science, and Google Scholar identified 179 eligible publications published between 1978 and 2023. Most studies focused on agronomic factors such as variety selection spacing arrangement and fertilizer management. Meta-analysis showed average LER values of 1.47 ± 0.046 for maize–soybean intercropping and 1.36 ± 0.081 for maize–mung bean intercropping indicating advantages over monoculture systems. However, inconsistencies in methodology and reporting standards limited study comparability and sustainability assessments. Future research should integrate ecological, social, and long-term economic indicators alongside standardized reporting frameworks to strengthen evidence-based intercropping recommendations nationally for sustainable agriculture.

The legal arrangement of cannabis in Indonesia is based on Article 28H paragraph (1) of the 1945 Constitution of the Republic of Indonesia which guarantees the right to health services, elaborated through Law Number 35 of 2009 concerning Narcotics and Law Number 17 of 2023 concerning Health. Cannabis is classified as a Group I narcotic prohibited for health services under Article 8 paragraph (1) of Law Number 35 of 2009, while Article 139 of Law Number 17 of 2023 requires that the use of medicines containing narcotics may only be carried out based on a prescription from medical personnel. At the same time, Canada through the Cannabis Act (S.C. 2018, c. 16) and Uruguay through Ley No. 19.172 (2013) apply fundamentally different legal arrangements for cannabis. This research uses normative legal research methods with a comparative law approach, applying the criminal policy framework of Marc Ancel and the law enforcement theory of Joseph Goldstein. The results show: (1) cannabis arrangement in Indonesia is prohibitive through Article 8 paragraph (1) of Law Number 35 of 2009, while Article 6 paragraph (3) opens a mechanism for reclassification through Ministerial Regulation; (2) Canada through the Cannabis Act applies a regulated market model with a CAD 11.4 billion legal industry and a 70% reduction in arrests, while Uruguay through Ley No. 19.172 applies a state monopoly with an 85% reduction in arrests without an increase in problematic use; (3) fundamental differences in legal systems, political systems, socio-cultural backgrounds, religion, and narcotics policy philosophy mean that the Canadian and Uruguayan models are not relevant to be directly applied in the Indonesian criminal law system.

This study analyzes normative conflicts in the evolution of local government regulations from Law No. 22 of 1999 to Law No. 23 of 2014, along with the changes following the Job Creation Law. The research background is grounded in the phenomenon of policy pendulum swings, which indicate a shift from radical decentralization toward structured centralization, as well as the disruptions caused by the omnibus law approach. The research aims to identify and classify vertical and horizontal normative conflicts and formulate recommendations for regulatory harmonization. The method used is normative legal research with a legislative and conceptual approach, employing Hans Kelsen’s theory of antinomy as an analytical tool. The research findings identified two main forms of normative conflict: first, a vertical conflict between Law No. 22/1999, which advocates for the broadest possible autonomy, and Law No. 23/2014, which strengthens central control through the concepts of absolute affairs and NSPK, creating a paradox of centralization within decentralization. Second, a horizontal conflict following the Job Creation Law, which centralizes regional licensing authority through the OSS system and revives Article 251 regarding the annulment of regional regulations that have been declared unconstitutional by the Constitutional Court. The implications of this research recommend revising problematic articles and strengthening the role of regions within a just decentralization system.

The observation of guidance and counseling activities was conducted at SDN 2 Pasaleman, located in Pasaleman Village, Kresna Street, Dusun Pon. This study aimed to identify the problems faced by students and to examine the role of teachers in implementing guidance and counseling services at the elementary school level. Data were collected through direct observation in the school environment and interviews with homeroom teachers. The results indicated several student-related issues, including verbal bullying such as teasing, low learning motivation, fighting behavior among lower-grade students, and a tendency to skip school among upper-grade students. These issues were influenced by peer environments, limited supervision, and low awareness of the importance of education. Teachers have made various efforts, including providing guidance, applying individual approaches, and maintaining communication with parents. Additionally, character values are integrated into daily learning activities. In general, guidance and counseling services have been implemented, but further improvement in more systematic strategies and broader support is still required.

This study examines the interpretation of the Qur’anic verse mentioning the lion in QS. Al-Muddathir [74]: 51 through the approach of tafsir ilmi (scientific exegesis). The aim of this research is to analyze the theological meaning of the term qaswarah, explore the interpretations of classical and contemporary exegetes, and relate them to the perspective of animal science as well as the underlying wisdom. This study employs a qualitative method with a library research approach, using primary sources from Qur’anic verses and classical tafsir works, and secondary sources from books, journal articles, and relevant scientific literature. The results show that the term qaswarah in QS. Al-Muddathir [74]: 51 has various interpretations, such as lion, hunter, or something frightening. However, most exegetes tend to interpret it as a lion due to its relevance to the context of the parable in the verse. The parable illustrates people who turn away from the truth like wild donkeys fleeing in fear from a predator. From the perspective of tafsir ilmi, this depiction aligns with scientific facts that identify the lion as an apex predator capable of triggering a fight-or-flight response in prey animals. Furthermore, the mention of the lion in the Qur’an is not merely descriptive but also contains theological, ecological, moral, and psychological values. The lion serves as a symbol to describe irrational human behavior in rejecting the truth. Thus, tafsir ilmi demonstrates a harmonious relationship between revelation and science, where natural phenomena are used as a medium to convey profound moral and spiritual messages.

This study aims to describe the implementation of instilling Islamic Religious Education values in the aspects of the Qur’an and Aqidah at TPQ Fattuhul Qulub, Doyo Baru District. The background of this research is based on the importance of Islamic religious education in shaping children’s character and morals from an early age amid the decline in the morality of the younger generation. TPQ, as a non-formal educational institution, has an important role in instilling Islamic values through learning the Qur’an, aqidah, and morals. However, in its implementation, several obstacles are still found, such as the low understanding of students regarding religious values, varying abilities in reading the Qur’an, and the lack of support from family and community environments.This study employed a descriptive qualitative approach. Data were collected through observation, interviews, and documentation at TPQ Fattuhul Qulub, Doyo Baru District. The focus of the research includes the planning, implementation, and evaluation processes of instilling Islamic Religious Education values in the aspects of the Qur’an and Aqidah.The results of the study indicate that the instillation of Islamic Religious Education values has been carried out through structured stages of planning, implementation, and evaluation. The learning process was conducted using the methods of Iqra’, tahsin, tahfidz, talaqqi, lectures, role modeling, habituation, and exemplary stories. In the Qur’anic aspect, students were guided to read the Qur’an according to tajwid rules and memorize short surahs, while in the Aqidah aspect, students were taught the pillars of faith, the attributes of Allah and His Messenger, and the formation of Islamic morals. The evaluation results showed improvements in Qur’anic reading skills, memorization, understanding of aqidah, and changes in students’ religious behavior, such as becoming more disciplined, polite, and diligent in worship. This success was supported by the exemplary behavior of the teachers and the involvement of parents in the learning process.

This study investigates the effect of total risk on firm performance and sustained growth among consumer non-cyclicals manufacturing companies listed on the Indonesia Stock Exchange (IDX) over the period 2019–2023. Total risk is operationalized through the systematic risk proxy (Beta/β), estimated via the Capital Asset Pricing Model (CAPM) framework as the covariance between individual stock returns and the market return divided by the variance of market returns, using the Jakarta Composite Index (JCI) as the market benchmark. Firm performance is measured through Return on Assets (ROA), Return on Equity (ROE), and Tobin’s Q, while sustained growth is operationalized following Gerson et al. (2025) as SG = b × ROE, where b denotes the earnings retention ratio. Panel data regression analysis is applied to 225 firm-year observations drawn from 45 companies, with model selection guided by the Chow and Hausman specification tests. The Fixed Effect Model (FEM) is adopted for ROA, ROE, and SG, while the Random Effect Model (REM) is applied for Tobin’s Q. Results indicate that systematic risk exerts a significant negative effect on ROA (β = −0.312; p < 0.01) and ROE (β = −0.278; p < 0.01), but is statistically non-significant for Tobin’s Q, suggesting that capital market pricing in Indonesia does not fully incorporate systematic risk information. Critically, systematic risk exerts the largest and most significant negative effect on sustained growth (β = −0.347; p < 0.01), revealing a dual transmission mechanism through which risk suppresses ROE while simultaneously inducing more conservative dividend policies, both of which constrain long-run growth sustainability. These findings carry important implications for corporate risk management strategy and empirically enrich the literature on risk, performance, and growth in emerging capital markets.

Vegetable stall businesses represent a common form of micro-enterprise that meets consumers' daily needs, including in the Depok District. However, most business owners have yet to adopt proper and adequate financial record-keeping practices, relying instead on manual methods. This makes it difficult to control and evaluate business financial management. This community engagement initiative aimed to provide guidance on digitizing accounting records for vegetable stall MSMEs using the BukuWarung application and to enhance the digital financial literacy of business owners regarding digital financial management. A quantitative descriptive approach was employed, involving observation, interviews, documentation, and direct assistance provided to vegetable stall owners in the Depok District. Observations revealed that business owners gained a better understanding of and improved skills in using the BukuWarung application, becoming capable of independently recording income, expenses, and business receivables and payables. The initiative demonstrated that implementing a guidance program for digitizing accounting records via the BukuWarung application significantly contributed to improving the financial management capabilities of vegetable-trading MSMEs. These findings suggest the potential for applying similar guidance models to MSMEs in other regions to foster broader digital financial literacy.

Recent Internet of Things (IoT) intrusion detection studies have reported near-perfect benchmark performance for Distributed Denial of Service (DDoS) detection, yet limited attention has been given to understanding how different traffic representations contribute to the detection process under highly imbalanced traffic conditions. This study presents an ablation-driven analysis to investigate the contribution of statistical and temporal representations for large-scale IoT DDoS detection using the CICIoT2023 dataset. Three experimental scenarios are evaluated, including statistical representation, temporal sequence representation, and hybrid statistical–temporal representation. Temporal representations are learned using a one-dimensional Convolutional Neural Network (1D-CNN) with lag-based traffic sequences, while ensemble tree-based classifiers are employed for final classification and representation analysis. In addition, multiple ablation configurations are designed to evaluate the impact of temporal dependency modeling and feature engineering strategies on detection performance. Experimental results show that statistical traffic representations remain highly effective for DDoS detection on CICIoT2023, achieving 99.36% accuracy and 99.31% weighted F1-score in the statistical representation scenario. Feature importance analysis further indicates that engineered statistical features contribute substantially more to the classification process than CNN-based temporal representations. Although temporal modeling captures sequential traffic behavior, its contribution is relatively limited and mainly acts as a complementary representation. Furthermore, the hybrid configuration produces only marginal improvements over the statistical representation alone. These findings highlight the importance of representation-level analysis for understanding the actual contribution of statistical and temporal modeling in modern IoT intrusion detection systems beyond relying solely on benchmark accuracy.

Bariatric surgery is effective in treating obesity and type 2 diabetes mellitus (T2DM); however, pregnancy occurring within 12–24 months after surgery carries significant risks. This report presents a complex pregnancy case in a patient with a history of sleeve gastrectomy, post-hemithyroidectomy hypothyroidism, and T2DM. A 29-year-old primigravida conceived 2 months after undergoing sleeve gastrectomy, which successfully induced T2DM remission, with HbA1c decreasing from 11% to 5.5%. Although glycemic control and euthyroid status were maintained throughout pregnancy, the patient developed severe preeclampsia at 35–36 weeks of gestation, complicated by intrauterine growth restriction (IUGR) and oligohydramnios. An emergency cesarean section delivered a male infant weighing 2000 grams with Apgar scores of 8 and 9 at the first and fifth minutes, respectively. The neonate required 14 days of NICU care due to respiratory distress syndrome, respiratory failure, and hyperbilirubinemia. Maternal gestational weight gain was suboptimal at only 4 kg, below the recommended range for pregnant women with obesity. This case highlights the importance of adhering to the recommended surgery-to-conception interval following bariatric surgery. Early pregnancy after surgery, combined with multiple metabolic comorbidities, may contribute to adverse maternal and neonatal outcomes. Multidisciplinary management, comprehensive nutritional monitoring, and optimization of comorbidities before conception are essential to improve pregnancy outcomes in this population.

Gestational hypertension is one of the leading causes of maternal mortality in Indonesia. Non-pharmacological interventions such as lavender aromatherapy have gained attention as complementary therapies due to their natural properties and minimal side effects. This study aims to evaluate the effect of lavender aromatherapy on blood pressure among pregnant women with gestational hypertension. The research employed a quasi-experimental design using a one-group pretest-posttest approach. A total of 15 participants meeting the inclusion criteria received an intervention consisting of lavender aromatherapy inhalation for 10–15 minutes. The results showed a decrease in mean systolic blood pressure from 141.53 mmHg before the intervention to 139.27 mmHg after the intervention. However, the mean diastolic blood pressure slightly increased from 90.20 mmHg to 90.27 mmHg. The reduction in systolic pressure indicates a potential relaxation effect of lavender, likely mediated through parasympathetic nervous system stimulation. Although the change in diastolic pressure was minimal and not clinically significant, these findings support the use of lavender aromatherapy as a supportive approach in managing blood pressure in pregnant women with gestational hypertension. This complementary therapy is expected to enhance maternal healthcare, particularly in improving comfort and reducing stress during pregnancy.

The findings indicate that the principal plays a strategic role in planning, implementing, and evaluating teacher performance appraisal through systematic academic supervision, including pre-observation, observation, and post-observation stages. The follow-up actions are carried out in a structured manner, ranging from guidance and warnings to rewards for high-performing teachers. The implementation of teacher performance appraisal has a positive impact on the quality of learning, such as improving teacher professionalism, creating active and engaging learning environments, and enhancing students’ motivation and learning outcomes. Therefore, the effective role of the principal in teacher performance appraisal is a crucial factor in improving educational quality.

Nile tilapia (Oreochromis niloticus) culture requires an efficient and low-cost feeding strategy that can support fry growth and survival. This study aimed to analyze the effects of three types of natural feed, namely silk worms, earthworms, and snails, on absolute length growth, absolute weight growth, and survival of Nile tilapia fry. The study was conducted at the Aquaculture Laboratory, Faculty of Science and Computer Science, Universitas Muhammadiyah Gorontalo, from January 31 to March 2, 2026. An experimental method was applied using a Completely Randomized Design consisting of three treatments and three replications. A total of 45 Nile tilapia fry were reared in 9 plastic containers filled with 10 L of water, with 5 fish in each container. Growth and survival data were analyzed using ANOVA at the 5% significance level, while water quality was analyzed descriptively. The results showed that the type of natural feed had no significant effect on absolute length growth, absolute weight growth, and survival. Descriptively, silk worms produced the highest length and weight growth, with values of 2.99 cm and 6.37 g, respectively. Snails produced the highest survival rate of 86.66%. Water quality remained stable, with temperature ranging from 26.3 to 26.8°C, pH from 7.6 to 7.9, and dissolved oxygen from 5.2 to 5.6 mg/L. These findings indicate that silk worms are potential natural feed for improving growth, while snails support the survival of Nile tilapia fry.

World Health Organization (WHO) reports that immunization is able to prevent approximately 3–5 million deaths each year; however, a number of children still do not receive optimal immunization coverage due to insufficient parental knowledge. This study aimed to analyze the effect of health education on improving mothers’ knowledge regarding early childhood immunization in RW 04, Kertamaya Subdistrict, Bogor City, in 2026. This study employed a pre- experimental design with a one-group pretest–posttest approach involving 30 respondents. Knowledge levels were measured using a questionnaire before and after the health education intervention and analyzed using the Paired Sample T-Test. The results indicated a statistically significant difference in mothers’knowledge levels before and after the health education intervention (p = 0.029). In addition, the proportion of respondents with good knowledge increased from 76.7% in the pre-test to 93.3% in the post-test. These findings demonstrate that health education has a significant effect on improving mothers’ knowledge and can serve as an effective promotive intervention to support the success of community-level immunization programs.
