Rapid population growth in Sidoarjo Regency has triggered massive land-use changes, resulting in increased surface runoff and reduced performance of the drainage system. This study aims to evaluate the hydraulic capacity of drainage channels in the Pondok Sidokare Indah Housing area against design flood discharges with return periods of 2, 5, and 10 years. The method used is a descriptive quantitative approach, involving hydrological analysis using maximum daily rainfall data from 2015–2025 and hydraulic modeling of the existing channel along 350 meters. The frequency analysis results indicate that the Log Pearson Type III distribution is the most suitable method based on statistical parameters and the Smirnov-Kolmogorov goodness-of-fit test. The calculation of design flood discharge using the rational method yields values of 0.749 m³/s (2-year), 1.003 m³/s (5-year), and 1.164 m³/s (10-year). Meanwhile, the maximum capacity of the existing channel ranges only between 0.534 m³/s and 0.733 m³/s. The comparison between hydrological load and channel capacity shows that all observation points (Sta 0+000 to Sta 0+350) are in overflow condition, even for the lowest return period flood discharge. This condition confirms that the current channel dimensions are no longer adequate and require normalization to mitigate annual flooding in the area.

Poor soil quality and inefficient nutrient utilization remain major constraints in tomato (Solanum lycopersicum L.) cultivation, often resulting in reduced plant growth, lower productivity, and suboptimal fruit quality. This study aims to evaluate the growth performance of rose tomatoes through the integration of open-field cultivation and hydroponic planting systems. The research methods included land preparation using the Pythagorean technique to ensure proper spacing and planting layout, the application of organic fertilizers to improve soil fertility, and the transition to a hydroponic drip irrigation system using rockwool as the growing medium during weeks 1 to 7 of plant development. Plant growth parameters, including plant height, leaf development, stem vigor, and overall plant health, were observed throughout the cultivation period. The results indicated that the combination of appropriate soil management practices and precise nutrient delivery in the hydroponic system significantly enhanced nutrient uptake and supported healthy plant growth. Furthermore, the drip irrigation system helped optimize water use efficiency while reducing nutrient losses. This integrated cultivation approach demonstrated its potential as an effective solution for maintaining crop quality and productivity, particularly in areas with limited land resources. Overall, the findings suggest that integrated management practices can provide a practical, efficient, and sustainable strategy for farmers seeking to improve horticultural production in modern agricultural systems.

Iron deficiency anemia (IDA) is a condition of insufficient iron that lowers hemoglobin levels and disrupts erythrocyte formation. This condition commonly occurs in children and can weaken the immune system, thereby increasing the risk of recurrent respiratory tract infections such as bronchiolitis, pneumonia, and Acute Respiratory Tract Infections (ARTI). Children with IDA are also at risk of worsening clinical conditions. This study employed a literature review method with a descriptive-analytical approach. A total of 10 journals (2020–2026) from Google Scholar, PubMed, ResearchGate, Elsevier, and the National Center for Biotechnology Information (NCBI) were analyzed using the Population, Intervention, Comparison, Outcome, Study Design (PICOS) framework and synthesized narratively. The results of the review indicate that iron deficiency anemia is significantly associated with an increased risk of recurrent respiratory tract infections in children. Children with IDA have a 2–5 times higher risk of developing bronchiolitis and pneumonia, and up to 10 times greater susceptibility to recurrent ARTI. This condition is also associated with increased disease severity, characterized by low hemoglobin levels, mean corpuscular volume (MCV), and serum iron, as well as elevated total iron-binding capacity (TIBC). Iron supplementation has been proven effective in reducing the incidence of recurrent infections. In conclusion, iron deficiency anemia is associated with an increased risk and severity of recurrent respiratory tract infections in children. Early detection and iron supplementation are essential to reduce morbidity and prevent infection recurrence.

Chili pepper (Capsicum annuum L.) is recognized as one of the horticultural commodities with significant economic value and an important contribution to food security in Indonesia. However, conventional cultivation practices still face various challenges, including limited land availability, climate uncertainty, and disturbances from plant pests and diseases. These conditions highlight the need for the implementation of innovative technologies to improve production efficiency while maintaining yield stability. One approach that has been increasingly developed is the hydroponic system, a cultivation technique that does not rely on soil as a growing medium but instead utilizes nutrient solutions as the primary source of essential elements. This article aims to examine various aspects of hydroponic chili cultivation, including the roles and benefits of the plant, different types of hydroponic systems, abiotic and biotic stress factors, and cultivation management strategies. Based on the review conducted, hydroponic systems, when supported by optimal nutrient management and environmental conditions, are capable of enhancing both the yield and quality of chili plants. Therefore, the development of hydroponic-based chili cultivation is considered to have promising prospects as a solution to support sustainable agriculture in the future.

The consistent decline in cucumber production in Indonesia indicates limitations in conventional cultivation systems, particularly due to land scarcity and inefficient resource management. This condition has encouraged the development of hydroponic systems as a more controlled and productive cultivation alternative. This study aims to critically analyze the key factors determining the success of hydroponic cucumber cultivation and to identify the most influential management aspects in improving yield. The method employed is a literature review, examining various recent studies related to hydroponic systems, nutrient management, growing media, and environmental factors. The results show that the advantages of hydroponics lie not only in land and water efficiency but also in the ability to precisely control growth variables. However, optimal productivity highly depends on the proper integration of nutrient management, particularly the regulation of pH, electrical conductivity (EC), and nutrient balance, as well as the control of environmental factors such as temperature, humidity, and light intensity. Inaccuracy in a single component can significantly reduce plant performance, even when other factors are optimal. Therefore, an integrated approach combining nutrient and environmental management simultaneously is essential to enhance hydroponic cucumber productivity. This study confirms that hydroponics has strong potential as a strategic solution to support sustainable agriculture amid land limitations in Indonesia.

The readiness of officers to carry out Electronic Medical Records (RME) needs to be measured using the Technology Readiness Index (TRI) method, which is an index used to measure the readiness of new technology users to achieve goals in daily life and work. This research aims to determine the readiness of Electronic Medical Record (RME) users using the Technology Readiness Index (TRI) case study at Daha Husada Regional Hospital. This is a descriptive research with an evaluation study where the research subjects are the head of medical records and 3 medical records officers in the inpatient registration section at Daha Husada Regional Hospital using a total saturated sampling technique. Data collection uses interview techniques. Data presentation is presented using narrative. The results of the research show that of the 4 variables used to measure the readiness of medical record users, medical record officers at Daha Husada Regional Hospital are ready to use medical records, even though they are ready there are still difficulties experienced and feelings of insecurity when using Electronic Medical Records (RME), namely Medical records can be accessed anywhere and are not yet integrated according to the user's wishes. Therefore, Daha Husada Regional Hospital should further tighten its electronic medical record data security system.

Knee septic arthritis is an orthopedic emergency that requires prompt and appropriate management to prevent permanent joint damage and systemic complications. Inflammatory markers such as erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are commonly used for diagnosis and monitoring of treatment response; however, their prognostic value after surgical debridement remains variable. This systematic review aimed to evaluate the role of ESR, CRP, and platelet count as prognostic indicators following irrigation and/or surgical debridement in patients with knee septic arthritis. A literature search was conducted in January using PubMed, Google Scholar, ScienceDirect, Wiley Online Library, SpringerLink, and Semantic Scholar, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Study quality was assessed using the National Heart, Lung, and Blood Institute (NHLBI) tools. Fifteen studies meeting the inclusion criteria were qualitatively analyzed. The findings indicate that elevated preoperative CRP levels and delayed postoperative CRP reduction are associated with unfavorable clinical outcomes, including failure of infection eradication and the need for repeat debridement. Although ESR is consistently elevated during the acute phase, its slower decline limits its short-term prognostic utility. Platelet count may increase as part of the systemic inflammatory response but shows inconsistent prognostic value.

Postharvest handling of leafy vegetables, such as kale (Brassica oleracea var. acephala), is crucial for maintaining product quality and market value. This study aims to review the application of sorting and grading processes in improving the quality of horticultural products. The method used is a literature review of scientific journals and relevant references related to postharvest handling of vegetables. The findings indicate that sorting functions to separate damaged and unmarketable products based on physical condition, while grading classifies products into quality categories based on size, shape, and visual appearance. These processes contribute to reducing postharvest losses, improving product uniformity, and increasing market value. Furthermore, proper sorting and grading support quality control and enhance efficiency in distribution and marketing systems. Therefore, sorting and grading are essential components of postharvest management to ensure product quality and market competitiveness.

This study examines the controversy surrounding the granting of investigative authority over electoral crimes to the Election Supervisory Body (Bawaslu) within the framework of the Integrated Law Enforcement Center (Sentra Gakkumdu). The research problem focuses on whether investigative authority should be directly assigned to Bawaslu and the main factors contributing to the suboptimal enforcement of electoral law in Indonesia. The study aims to analyze the effectiveness of the institutional design of Sentra Gakkumdu and to formulate an ideal model for electoral law enforcement in Indonesia. This research employs a normative legal method with statutory, conceptual, and comparative approaches. The analysis is strengthened through bibliometric mapping using the VOSviewer application to examine the development of studies on electoral law enforcement and institutional design, as well as by comparing Indonesia’s electoral law enforcement system with those of Norway, New Zealand, and Sweden. The findings indicate that the primary issue does not lie in the absence of investigative authority within Bawaslu, but rather in the limited investigation timeframe, weak interinstitutional coordination, and inflexible regulations.

Maternal hypertension remains one of the major contributors to maternal morbidity and mortality in Indonesia and globally. This study aimed to analyze the prevalence, mortality trends, and geographical disparities of maternal hypertension in Indonesia during the 2022–2023 period. The research employed a descriptive design using secondary data obtained from official reports of the Indonesian Ministry of Health, national health surveys, and Maternal Perinatal Death Notification (MPDN) data. Data analysis was conducted descriptively by examining prevalence rates, maternal mortality due to hypertension, regional distribution, and temporal trends across provinces in Indonesia. The findings showed a slight but consistent decline in both the prevalence and mortality rates of maternal hypertension from 2022 to 2023 in most provinces. However, significant regional disparities remained evident. Provinces in eastern Indonesia, including Papua Barat, Nusa Tenggara Timur, Maluku, and several provinces in Sulawesi and Kalimantan, consistently recorded higher prevalence and mortality rates compared to provinces in Java and Bali. Meanwhile, provinces with better healthcare infrastructure and maternal referral systems demonstrated lower mortality outcomes. The study also revealed a strong association between high prevalence and increased maternal mortality, indicating the importance of healthcare accessibility, antenatal care quality, and emergency obstetric services in reducing maternal health burdens. These findings emphasize the need for region-specific maternal health interventions, improved healthcare distribution, early detection programs, and strengthened referral systems to reduce maternal hypertension disparities and improve maternal health outcomes in Indonesia.

The development of information technology has encouraged the transformation of government administration toward digital-based governance, including correspondence management systems. Digital correspondence governance plays an important role in improving administrative effectiveness, bureaucratic efficiency, and the quality of public services. However, the implementation of digital correspondence systems in local government institutions still faces several challenges, including limited system integration, inadequate human resource capacity, and unstandardized electronic archive management. This study aims to analyze and construct a digital correspondence governance model in realizing administrative effectiveness at Dinas Komunikasi, Informatika, Statistik dan Persandian Kabupaten Gowa. This study employed a qualitative approach with a descriptive research type. Data collection techniques were conducted through observation, in-depth interviews, and documentation. Research informants were selected using purposive sampling techniques, while data analysis employed the interactive model of Miles, Huberman, and Saldaña through data condensation, data display, and conclusion drawing. The results indicate that the implementation of digital correspondence governance has improved the speed of document disposition, administrative efficiency, accessibility of documents, and organizational work coordination. However, the implementation has not been fully optimal due to constraints in system integration, human resource capacity, and digital archive management. This study produced a digital correspondence governance model emphasizing the strengthening of information technology, enhancement of employee competence, integration of administrative systems, and development of a digital work culture. It is recommended that government institutions strengthen the integration of digital correspondence systems, improve employee competencies, and establish sustainable electronic archive management standards.

Abstract: Detecting chili leaf diseases remains challenging due to the non-uniform manifestation of symptoms, local discoloration, small lesion regions, and visual similarity between disease patterns and natural leaf background variations. Although YOLO-based detectors provide favorable computational efficiency, lightweight variants often struggle to distinguish subtle lesion characteristics, while conventional attention mechanisms such as CBAM primarily rely on global feature aggregation and may overlook regional activation variability. To address these limitations, this study proposes a YOLOv9s-based detection framework integrated with a Region-Dispersion Channel Spatial Attention (RDCSA) module. The proposed module incorporates regional dispersion statistics, namely mean, standard deviation, and range, as channel descriptors to capture inter-region feature variability before applying spatial attention refinement. Experiments were conducted on the COLD dataset containing 532 original images from five chili leaf condition categories using a split-before-augmentation protocol to ensure objective evaluation. RDCSA was integrated at the P5 feature level and evaluated through attention placement analysis, component-wise ablation, sensitivity analysis, stability assessment, and comparison with modern attention mechanisms. The proposed YOLOv9s + RDCSA model achieved an mAP@50 of 0.894, mAP@50–95 of 0.773, precision of 0.858, recall of 0.861, and an F1-score of 0.859 with only a marginal increase in model parameters. The results suggest that regional dispersion-based attention improves feature discrimination while preserving computational efficiency, particularly for disease symptoms characterized by heterogeneous spatial patterns. Nevertheless, performance remains influenced by visually ambiguous symptom categories, indicating that further validation across multiple datasets and field conditions is required. Overall, the proposed RDCSA module enhances detection capability without substantially increasing computational overhead, making it a promising attention mechanism for lightweight plant disease detection systems.

This study examines the performance of student administrative services in the Society 5.0 era at the Bureau of Academic Affairs, Student Affairs, and Planning of Gorontalo State University, focusing on scholarship services. It addresses the need for accessible, responsive, transparent, inclusive, and student-centered administrative services in higher education. A descriptive qualitative approach was employed through in-depth interviews, participatory observation, and document analysis. Informants included bureau leaders, scholarship and financial aid administrators, operational officers, and students receiving various scholarship schemes. Thematic analysis was conducted through data reduction, data display, and conclusion drawing, while validity was ensured through source triangulation, method triangulation, and member checking. The findings show that accessibility has improved through service counters, websites, social media, WhatsApp, online forms, SIMPEL BAKP, and coordination with faculties and study programs. However, information remains fragmented, digital standard operating procedures are not uniform, and disability-inclusive access is limited. Responsiveness is supported by direct and digital communication, but it lacks a dedicated complaint system, automatic notifications, selection-status dashboards, and real-time disbursement tracking. Service quality is perceived as fairly good because students experience professional, friendly, and fair treatment. Nevertheless, service documentation, procedural standardization, staff training, and humanistic technology integration need strengthening. The study concludes that scholarship administration should be transformed into a centralized, inclusive, responsive, transparent, and student-centered digital-humanistic service model.

This study aims to analyse the legal status of physical possession evidenced by a Letter C under land law, as well as the issue of legal certainty in the resolution of land disputes by the state. Many members of the public still rely on a Letter C as proof of possession of the land they own, even though this document serves only as administrative evidence and not as a strong instrument of proof of ownership. This study employs a juridical-normative legal research method using a legislative approach and a conceptual approach. The legal materials were gathered through a literature review and analysed qualitatively, with the findings presented in a descriptive format. The results indicate that Letter C possesses relatively weak evidential weight as it is merely an administrative record that does not follow the procedures within the land registration system as stipulated by the UUPA. Currently, Letter C serves only as a guide and therefore no longer possesses legal force equivalent to a certificate. The land system in Indonesia adopts a negative publication system with a positive tendency, meaning that a certificate constitutes strong evidence of rights, but may still be revoked if another party is able to prove their rights.

This study examines the regulation of copyright royalties as joint property in Indonesia, the United States, and Europe, aiming to provide recommendations for better legal implementation. The research employs a normative juridical method with a comparative legal approach, utilizing library research and qualitative analysis of primary and secondary legal materials. The findings indicate that Indonesia, the United States, and Europe share common ground in recognizing royalties derived from copyright as joint property when such economic benefits are obtained during marriage. However, significant differences exist in their approaches. European countries, particularly Spain and the Republic of Moldova, clearly distinguish between exclusive rights and economic rights, where copyright remains the creator's personal property while royalties are classified as joint property. The United States demonstrates considerable flexibility through state-level regulations, adopting either community property systems or equitable distribution systems. Indonesia, through Decision No. 1622/PDT.G/2023/PA.JB, has begun recognizing royalties as joint property. Nevertheless, Indonesia still requires clearer and more comprehensive regulations to ensure legal certainty regarding the status of royalties as joint property and their distribution following divorce. This study contributes to developing legal frameworks that balance protecting creators' personal rights with the principle of fairness in family law.

This study aims to analyze the paradox of stunting in Yemen, particularly the disconnect between humanitarian response priorities and children's actual nutritional needs amid the ongoing conflict. Stunting, a form of chronic malnutrition, is a significant public health issue in Yemen, exacerbated by the conflict's disruption of food, healthcare, and sanitation systems. Despite the clear evidence of rising stunting rates, international humanitarian interventions tend to focus on addressing acute crises, such as extreme hunger, while neglecting long-term nutritional needs. Using a qualitative literature review approach, the research synthesizes data from archival documents, reports, and secondary sources to explore the structural causes of stunting and the challenges faced by humanitarian actors in Yemen. The findings reveal that the protracted conflict, economic collapse, and humanitarian blockades have worsened food insecurity and malnutrition. Moreover, the humanitarian response often prioritizes short-term survival over long-term prevention of stunting, resulting in a lack of integrated, multisectoral interventions. The study emphasizes the need for a paradigm shift in humanitarian policies to incorporate long-term development strategies and integrate stunting prevention. This research contributes to the academic understanding of the humanitarian-development nexus and offers recommendations for more holistic interventions.

The digital transformation of the Indonesian judicial system through the implementation of e-court and e-litigation necessitates a redefinition of conventional evidentiary laws, which have historically been governed by the Herziene Inlandsch Reglement (HIR) and the Rechtreglement voor de Buitengewesten (RBg). This research aims to analyze the evidentiary strength of electronic documents as expanded means of proof in civil proceedings and to identify the challenges regarding their implementation. The research method employed is normative legal research using a statutory approach and a conceptual approach. The findings indicate that based on the principle of functional equivalence, electronic documents hold a legal status equivalent to paper-based documents, provided they meet the requirements of integrity, accessibility, and authenticity through certified electronic signatures as mandated by Law Number 1 of 2024 concerning Electronic Information and Transactions. The evidentiary strength of an electronic document may reach the level of conclusive evidence, similar to an authentic deed, if supported by a reliable electronic system. However, implementation still faces technical hurdles concerning metadata verification and limited human resource competency within the judiciary. This research recommends the urgent need for a new codification of civil procedural law and the standardization of digital forensic procedures in trials to ensure legal certainty and justice for all parties in the digital era.

The development of information and communication technology has increased the use of electronic documents in legal and business activities, thereby affecting the evidentiary system in Indonesian civil procedural law. This study aims to analyze the legal regulation of electronic evidence and its evidentiary strength in resolving civil cases under Indonesian civil procedural law. The research method used is normative juridical research with statutory and library research approaches. The data were obtained from primary and secondary legal materials and analyzed qualitatively. The results show that electronic evidence has been legally recognized through Law Number 11 of 2008 in conjunction with Law Number 19 of 2016 concerning Electronic Information and Transactions. Its evidentiary strength has the same legal position as other forms of evidence as long as it fulfills the requirements of authenticity, integrity, and validity of electronic data. Therefore, more detailed regulations regarding authentication standards and examination procedures for electronic evidence are still needed to ensure legal certainty in civil court practices.

Indonesia, as a country located at the intersection of three tectonic plates, is highly vulnerable to earthquakes. This has led to the development of various innovations in earthquake-resistant housing. An interesting phenomenon can be found in Sigi District, Central Sulawesi, where several vernacular houses of the Kaili people constructed with a hybrid design (wooden frame and mud walls) have proven to withstand the major earthquake that struck Palu, Central Sulawesi, in 2018. This study aims to examine the architectural typology of non-engineered hybrid houses within the Kaili community using a qualitative descriptive approach and typological analysis. Data collection involved direct observation, interviews, and literature reviews, with a focus on the spatial and physical systems of the buildings. The sample for the study was determined through purposive sampling with specific criteria. Data analysis was conducted using a qualitative descriptive approach. The results of the study indicate that, despite changes in materials due to adaptations to technological advancements and reconstruction policies, the spatial layout and fundamental structure of the houses have maintained traditional philosophies. These houses demonstrate the integration of cultural values, local knowledge about seismic activity, and the use of local materials, which allow for both structural flexibility and some rigidity, contributing to the buildings’ resilience. These findings highlight the importance of combining technical and cultural approaches in designing earthquake-resistant houses within a local context.

Land rights disputes arising from overlapping land certificates remain a complex agrarian law issue frequently encountered in Indonesia. This phenomenon reflects weaknesses in the land administration system, particularly in data collection, land measurement, and certificate issuance. Such disputes create conflicts, legal uncertainty, and reduced public trust in the land registration system. In practice, these disputes are generally resolved through civil litigation procedures in the District Court. This study aims to comprehensively analyze civil procedural law in resolving land rights disputes involving overlapping certificates and to examine the evidentiary strength of land certificates in judicial proceedings. This research employs a normative legal method using statutory and conceptual approaches, supported by primary and secondary legal materials. The findings indicate that dispute resolution begins with the filing of a lawsuit, followed by mediation, court examination, and the evidentiary process as the most crucial stage in determining lawful ownership. Land certificates serve as strong evidence; however, they are not absolute, as they may be challenged if administrative or substantive legal defects are identified. Judges play a central role in assessing certificate validity by considering land history, physical possession, good faith, and compliance with legal procedures. Nevertheless, the effectiveness of dispute resolution still requires improvement through better land administration, enhanced data accuracy, and stronger institutional integration.
