Sandstone aquifers in tropical sedimentary basins are major groundwater reservoirs, yet their public-health safety is often underestimated when assessment is restricted to physicochemical quality. This review addresses the persistent mismatch between chemically acceptable groundwater and microbiologically unsafe water, especially in shallow, permeable aquifers exposed to intense rainfall, pit latrines, septic systems, dumpsites, agricultural runoff, and weak wellhead protection. A structured narrative synthesis was conducted using peer-reviewed hydrogeological, hydrogeochemical, microbiological, vulnerability, and environmental health studies from Scopus, Web of Science, ScienceDirect, SpringerLink, and Google Scholar. The review focused on tropical sandstone aquifer systems in Africa, Asia, and South America. It examined lithological controls, major-ion evolution, microbial indicators, contamination pathways, WHO-based classification, Water Quality Index applications, contamination indices, multivariate statistics, GIS-based vulnerability mapping, and integrated hydro-microbial risk scoring. The synthesis shows that groundwater chemistry is governed mainly by silicate weathering, carbonate dissolution, cation exchange, shale interbeds, residence time, and anthropogenic inputs. However, chemical compliance does not confirm potable safety. Reported evidence includes TDS below 500 mg/L in chemically acceptable Nigerian basin aquifers, while all 12 shallow wells in Abeokuta tested positive for total coliform and Escherichia coli. Microbial loads increased during wet seasons, with Calabar groundwater recording total coliform increases from 76 to 468 CFU/100 mL and Salmonella/Shigella reaching 1081 CFU/100 mL. DRASTIC mapping further classified 21% of the Dahomey Basin as highly vulnerable. The review therefore proposes an integrated framework linking hydrochemistry, microbial evidence, vulnerability, GIS, and health-risk interpretation for safer, adaptive, and evidence-based groundwater governance.

Dredger operations in water-based mining areas have a high occupational risk because they involve a combination of wet environments, mechanical equipment, and electrical systems. The presence of electrical panels, power cables, terminal connections, electric motors, inverters/drives, and protection components on the Dredger requires a sound understanding of Occupational Health and Safety, particularly electrical safety. Water splashes, wet walking surfaces, high humidity, and improper procedures during inspection or cleaning may increase the risk of short circuits, protection trips, and electric shock. Therefore, structured basic safety training is required so that operators are able to identify electrical hazards and implement safe working procedures. This activity aimed to improve operators’ understanding of hazardous electrical components, initial safety briefing procedures, measurement practice and safe handling during trips or short-circuit indications, and the correct and safe use of water pumps for unit cleaning. The activity was carried out through field observation, technical briefing, direct demonstration on the electrical panel and work area, simple measurement practice, and safe cleaning practice. The results indicate that field documentation can serve as an effective learning medium to strengthen operators’ understanding of electrical hazard sources on the Dredger, the application of simple lock out-tag out procedures, the control of wet areas, and the limitation of water spray direction during cleaning activities. Overall, the activity shows that improved compliance with safety procedures may reduce the risk of short circuits and electric shock during operation and maintenance.

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.

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 aims to gain an in-depth understanding of the legal reasoning used by judges in the Administrative Court (PTUN) in annulling State Administrative Decisions (KTUN), as well as to examine the legal implications for the parties involved and the overall system of government administration. This research employs a normative juridical method with three approaches: statutory, conceptual, and case approaches. The analysis was conducted qualitatively by studying reference books and reviewing court decisions. The study shows that the annulment of KTUN by PTUN judges is based on three important factors, namely lack of authority (ultra vires), procedural defects, and substantive defects in the decision. In addition, violations of the General Principles of Good Governance (AUPB), such as the principles of legal certainty, prudence, and proportionality, also constitute important considerations for judges. In the judicial process, judges not only consider the formal aspects of the law, but also take into account substantive justice in order to protect citizens’ rights from improper governmental actions. The implications of the annulment of KTUN include the restoration of the plaintiff’s rights through the process of restitutio in integrum, the obligation of administrative officials to revoke or correct the issued decision, as well as the potential impact on third parties involved in the decision. In general, the annulment of KTUN serves as a legal control mechanism over government administration while also encouraging the realization of good and transparent governance within a state governed by the rule of law.

This study aims to analyze the effectiveness of the implementation of fixed asset accounting systems and procedures at the Department of Transportation of Medan City. The research employs a qualitative approach with a descriptive method to gain an in-depth understanding of actual field conditions. Data were collected through observation, interviews, documentation, and literature review, involving four informants directly engaged in fixed asset management. The results indicate that the implementation of fixed asset accounting systems and procedures has been relatively effective, as reflected in the execution of asset management stages in accordance with applicable regulations and the utilization of information technology-based systems. These systems support more structured recording and reporting processes. However, the effectiveness has not been fully optimized due to several constraints encountered during implementation. Factors influencing effectiveness include the quality of human resources, the use of technology, data completeness, and coordination among work units. The identified challenges involve data inaccuracies, limited user competence, weak internal control, and technical issues within the system. These conditions affect the quality of financial reports, particularly in terms of accuracy and timeliness, and also influence the effectiveness of internal control. This study contributes by identifying key issues and highlighting the importance of improving system quality and human resource capacity to support more effective and accountable fixed asset management.

High-quality forage selection is a central factor in improving Bali cattle performance, particularly in smallholder systems that rely heavily on local feed resources. This study evaluated the effects of odot grass (Pennisetum purpureum cv. Mott) and pakchong grass (Pennisetum purpureum cv. Thailand) on feed intake, average daily gain, and feed conversion ratio of male Bali cattle. The experiment was conducted for 30 days from February to March 2026 at CV. RnB Farm, Gorontalo Regency. Nine male Bali cattle with relatively homogeneous initial body weights of 150–200 kg was assigned to a completely randomized design with three treatments and three replications. The treatments were P0, field grass as the control; P1, 100% odot grass plus concentrate; and P2, 100% pakchong grass plus concentrate. Dry matter intake did not differ significantly among treatments, with values of 6.47 ± 0.19, 6.52 ± 0.19, and 6.55 ± 0.16 kg/head/day for P0, P1, and P2, respectively. In contrast, average daily gain differed significantly, with the highest value observed in P2 at 0.56 ± 0.08 kg/head/day, followed by P1 at 0.52 ± 0.09 kg/head/day and P0 at 0.45 ± 0.06 kg/head/day. Feed conversion ratio also differed significantly, with the most efficient value recorded in P2 at 11.98 ± 2.10. These findings indicate that pakchong grass combined with concentrate provides the best feed efficiency and growth performance, while odot grass remains a promising alternative forage for improving Bali cattle productivity.

This study examines the systemic transformation of Japan’s refugee and immigration policy from 2021 to 2025, exploring how humanitarian paradigms have been superseded by state security considerations. The research aims to analyze how Japan constructs refugees as an existential threat to legitimize its restrictive reception regime, synthesizing Realism and Constructivism to explore the intersection of securitization, national interest, and identity. Methodologically, this paper employs a qualitative interpretive case study by integrating Ruth Wodak’s Discourse-Historical Approach (DHA) and Interpretive Process Tracing (IPT) to examine government texts, policy documents, and parliamentary debates. The findings reveal a profound policy asymmetry driven by intersubjective threat framing and institutionalized topoi (abuse, threat, law and order). Ukrainian displaced persons are positively categorized as evacuees (hinanmin) to align with G7 geopolitics, whereas traditional asylum seekers are pejoratively labeled as "repeated applicants" and framed as threats to public order, social harmony (wa), and ethnic homogeneity (tan’itsu minzoku). This discursive construction successfully legitimizes extraordinary measures within the 2023 amendment of the Immigration Control and Refugee Recognition Act (ICRRA), including the abolition of automatic deportation suspensions and the expansion of a surveillance state via alternative monitoring (kanri sochi). Ultimately, this study demonstrates that international norm compliance is deeply mediated by domestic cultural appropriateness (nihonjinron). It implies the necessity for future ethnographic research on grassroots impacts and suggests transparent asylum evaluation metrics aligned with non-refoulement principles.

Data security in Electronic Medical Records (EMR) is a crucial issue in health information governance in Indonesia. This study evaluates the compliance of health facility information security systems with Ministry of Health Regulation (PERMENKES) No. 24 of 2022 and Personal Data Protection Law (UU PDP) No. 27 of 2022, and analyzes the impact of non-compliance on service quality and patient trust. The method employed is a systematic narrative literature review on the Google Scholar database (2023–2026) using the keywords "data security and privacy," "electronic medical records," and "CIA Triad," focusing on the implementation of Confidentiality, Integrity, and Availability. The four healthcare facilities examined have implemented controls such as role-based access control, Electronic Signatures (TTE), Virtual Private Networks (VPN), data encryption, and SSL/TLS protocols in accordance with PERMENKES provisions and Article 35 of the UU PDP. However, the effectiveness of implementation is hindered by weak authentication due to the use of simple passwords and excessively long auto-logout durations, the absence of comprehensive written standard operating procedures (SOPs), low staff compliance with security protocols, and minimal patient awareness regarding personal data protection rights. These weaknesses heighten the risk of patient data breaches as well as potential administrative sanctions and fines, and carry negative implications for service quality and public trust. Recommendations include strengthening internal security policies, developing written SOPs, providing continuous training for healthcare workers, implementing stronger authentication mechanisms (e.g., multi-factor authentication/MFA), and conducting patient awareness programs to ensure regulatory compliance and maintain public confidence.

The Family Hope Program (Program Keluarga Harapan/PKH) is Indonesia's primary conditional cash transfer (CCT) scheme for poverty alleviation. This study examines PKH effectiveness in improving household welfare among beneficiaries in Oebobo District, Kupang City, East Nusa Tenggara (NTT), employing a Three-Stage Least Squares (3SLS) simultaneous equation approach. The analysis integrates a Gender Equality, Disability, and Social Inclusion (GEDSI) perspective to evaluate Access, Participation, Control, and Benefit (APCB) dimensions for vulnerable groups. A mixed-methods explanatory sequential design was applied to 151 beneficiary households selected via proportional sampling across three urban sub-districts. The 3SLS estimations establish that targeting accuracy (X1) and economic empowerment (X3) are the most significant determinants of PKH effectiveness; PKH effectiveness (Y1) strongly shapes household governance (Y2) through the Family Capacity Building Meetings (P2K2) mechanism; and PKH effectiveness is the dominant determinant of household welfare (Y3), with a near-unity coefficient (β=0.97). GEDSI analysis reveals that female-headed households, the elderly, and persons with disabilities face compounding vulnerabilities inadequately addressed by current program design. The study recommends strengthening data verification systems, embedding economic empowerment as a core pillar, and adopting differentiated targeting based on intersectional vulnerability profiles.

In addition, this system is equipped with an adaptive alarm feature that can be controlled through the website so that users can set alarms according to their needs. The research method used is an experimental method with a descriptive approach through the stages of system design, hardware and software implementation, and system testing. Based on the test results, the system successfully displays weather information in real-time and runs automatic alarms according to user settings. With this system, users can obtain weather information and time reminders more effectively, practically, and efficiently.

This study aims to explain the construction of gender identity in Toni Morrison's novel Beloved through Judith Butler's gender performativity theory. This novel tells the story of the traumatic experience of slavery that shapes racial identity as well as the social issues, power relations, and extreme violence depicted within it. This study explains how Sethe and other female characters in the novel Beloved construct and demonstrate their identities through concrete actions as a form of protest against slavery. Based on Judith Butler's performativity approach, identity is not understood through a fixed biological destiny but rather as a repetition of social practices and norms within society. In the novel Beloved, Black women are represented not as a fixed biological essence but as the result of the application of norms in society. In Beloved, the Black female body is depicted as a source of oppression and a space of resistance. The system of slavery in Beloved not only controls the physical body but also women's subjectivity. Sethe's actions in protecting her child in the novel can be read as an attempt to shake up hegemonic maternal norms. The results of this study indicate that Morrison portrays identity as a political construct and always in the process of becoming. The trauma depicted in the novel is a performative mechanism that shapes the characters' subjectivities. Thus, an analysis of gender performativity in Beloved cannot be separated from the intersectional issues of race, history, slavery, and patriarchal culture.

The Food & Beverage industry relies heavily on the availability and quality of fresh raw materials, making inventory management crucial. This study aims to analyze the implementation of the First-In, First-Out (FIFO) method in inventory management at PT K Hospitality Investment. The research design used a case study. Data were collected through interviews, observation, and documentation, then analyzed descriptively and qualitatively to assess the implementation of the FIFO inventory method in inventory management. The results show that PT K Hospitality Investment adopts a strict chronological inventory system and issuance of goods based on the order of entry. The use of FIFO inventory is often supported by the FEFO (First-Expired, First-Out) technique. Integrated inventory control has contributed to the financial stability of PT K Hospitality Investment. When properly implemented, the FIFO method not only helps reduce waste and increase efficiency, but also supports the company's operational sustainability. Although the implementation has been successful, the company still faces challenges such as limited infrastructure, a manual recording system, sudden changes in trends or guest order volumes, and delays in supplier deliveries.

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.

This study aims to analyze the implementation of educational marketing management in increasing the interest of new students at MTs Negeri 3 Bekasi City, with a focus on the application of the POAC management functions (Planning, Organizing, Actuating, Controlling). The study employs a descriptive qualitative approach using a case study design. Primary data were obtained through observation and in-depth interviews with the Madrasah Principal and the Vice Principal for Student Affairs, who serves as the Chair of the PMBM Committee, while secondary data were sourced from relevant journals and literature. The research results indicate that marketing planning was carried out systematically through the formation of the PMBM committee, academic, religious, and Quranic literacy selection processes, as well as the utilization of digital and print media. Organization involved all school components in a structured manner, while promotional activities highlighted students’ academic, non-academic, and moral achievements through social media and word of mouth. This strategy proved effective, as evidenced by the number of applicants far exceeding the admission quota. However, implementation still faces challenges related to funding, limited land availability, and public perceptions regarding the difficulty of the selection process, which are addressed through routine evaluations and collaboration with government agencies.

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.

The absence of integrated blood stock management in hospitals, relying on current manual procedures, frequently results in delayed services and challenges in fulfilling blood requirements under emergencies. This research seeks to design and build a web-based blood stock monitoring platform called HemoBridge, offering real-time data accessible by the public, healthcare facilities, and the Ministry of Health. The System Development Life Cycle (SDLC) framework with the well-known Waterfall approach was adopted, encompassing needs analysis, system architecture, development, verification, deployment, and upkeep. This study used a qualitative methodology through field observation and literature review. The platform was developed using PHP and the Laravel framework, with HTML, CSS, JavaScript, and MySQL as supporting technologies. Findings indicate HemoBridge was successfully deployed with core features comprising a comprehensive landing page, donor education, role-based access control, an integrated hospital management panel, a Ministry of Health dashboard, and an advanced blood stock search module with referral capability. Validation through Black Box Testing across six primary functions confirmed all features performed as intended. The platform demonstrates the capacity to enhance data management efficiency, accelerate information retrieval, and strengthen evidence-based decision-making in healthcare. Prospective enhancements include automated stock alerts, data encryption, and wider interoperability with health institutions throughout Indonesia.

Cigarette smoke is a major source of free radicals that can cause various health problems, including disturbances in the male reproductive system. Nicotine and other harmful compounds in cigarettes increase oxidative stress and interfere with spermatogenesis. Gotu Kola (Centella asiatica) is a medicinal plant known for its antioxidant properties that may help neutralize free radicals. This study aimed to determine the effect of Gotu Kola leaf extract on the histopathological features of the testes in male Wistar rats exposed to cigarette smoke. An experimental study using a Post-Test Only Control Group Design was conducted on 24 rats divided into six groups: a normal group, a negative control group exposed to cigarette smoke, a positive control group treated with vitamin E, and three treatment groups receiving Gotu Kola extract at doses of 120, 180, and 240 mg/kg body weight for 28 days. The observed parameters were Leydig cell count and seminiferous tubule diameter. One-way ANOVA analysis showed that Gotu Kola extract significantly increased Leydig cell numbers and seminiferous tubule diameter in all treatment groups compared to the negative control group (p < 0.05). Post hoc analysis demonstrated significant differences in tubule diameter, with the highest improvement observed at the 240 mg/kg body weight dose. These findings indicate that Gotu Kola extract has potential protective effects against testicular damage caused by cigarette smoke exposure.
