Abstract

This study aims to examine in depth the implementation and violations of the engineering code of ethics in the Hambalang National Education, Training, and Sports School (P3SON) Project. The Hambalang Project, which experienced structural failure due to neglect of geotechnical engineering principles and political collusion, is used as a case study of systemic failure. The analysis focuses on violations of the Sapta Dharma of the Indonesian Engineers Association (PII) and the evaluation of professional responsibility based on ethical theories (Deontology, Teleology, and Virtue Ethics). The analysis results indicate that ethical violations, especially conflicts of interest and systemic corruption, are the main causes that trigger technical violations (ignoring the risks of expansive clay soil). The identified fundamental violations are Sapta Dharma Point 1 (Prioritizing Public Safety), Point 2 (Working According to Competence), and Point 4 (Avoiding Conflicts of Interest). Recommendations proposed include systemic solutions such as the separation of critical contracts and mandatory independent design validation (peer review) to strengthen the culture of engineering ethics.

Abstract

The tragic collapse of Champlain Towers South (CTS) in Surfside, Florida, on June 24, 2021, was a progressive structural failure that killed 98 people and became one of the most significant civil engineering disasters in recent decades. Engineering investigations indicated that the failure initiated in the transfer slab and pool deck area, which experienced severe degradation due to waterproofing failure, chloride penetration, reinforcement corrosion, and spalling, which reduced the load-bearing capacity of the elements. A 2018 report by Morabito Consultants identified “major structural damage” to the slab and columns above the underground garage, but repair recommendations were not promptly implemented by the building owner. This delay was exacerbated by inconsistent subsequent technical interpretations and ineffective risk communication. This study evaluates the CTS tragedy through an engineering ethics approach using the Indonesian Engineers Association (PII) Code of Ethics framework, including Sapta Dharma and Catur Karsa, as well as the theories of deontology, utilitarianism, and virtue ethics. The analysis results show that the engineer's obligation to prioritize public safety (duty to warn) takes higher priority than contractual obligations to the client. Failure to formally escalate to regulators when a building owner fails to respond to critical findings constitutes an ethical violation that contributed to the lack of mitigation before progressive collapse. Furthermore, indications of conflict of interest and a lack of professional rigor worsen the quality of technical decision-making. As a practical contribution, this study proposes the implementation of a “Structural Hazard Mandatory Reporting Protocol” that includes imminent hazard criteria, a tiered reporting mechanism, response deadlines, and protections for reporting engineers. This study emphasizes the importance of integrity, moral courage, and improved structural inspection standards to prevent similar failures in the future.

Abstract

The legal protection of Kurash athletes’ rights is a shared responsibility between the central and regional governments. Guarantees regarding decent income, health insurance, career advancement, appreciation, and performance bonuses must be optimized and distributed fairly to all Kurash athletes. This study aims to examine the extent of the implementation of Law No. 11 of 2022 on Sports and related regulations, as well as to identify obstacles in fulfilling athletes’ rights. The research applies a juridical-empirical method with descriptive analysis, analyzing Law No. 11 of 2022 and collecting data through interviews with relevant informants. The findings reveal that although regulations protecting athletes’ rights exist, the implementation of legal protection for Kurash athletes remains suboptimal. The inhibiting factors include budget constraints, limited government attention to non-Olympic sports, and the persistence of corruption among certain organizational officials. This study emphasizes the importance of collaboration between the government, sports organizations, and society to create a fair and sustainable ecosystem for the development of Kurash athletes.

Abstract

The coastal area of Nusaniwe District in Ambon City is a dynamic and dense area of human activity, such as ports, settlements, and industries. This condition makes the area vulnerable to shoreline changes triggered by natural factors and human activities. This study aims to analyze changes in the coastline of Nusaniwe District during the period 2015-2024 using Landsat 8-9 satellite imagery which was analyzed using the Digital Shoreline Analysis System (DSAS) method based on Net Shoreline Movement (NSM) and End Point Rate (EPR) parameters. The results of the analysis show that the change in the coastline in this region is dominated by retreat, especially in area C (Negeri Latuhalat) with an average change of 11.98 meters from 2015-2024. Meanwhile, area E (Wainitu Village) experienced an advanced coastline with an average change of 4.28 meters. The total area of identified coastline changes is 35,573 Ha, consisting of 24,867 Ha of backward coastline and 10,707 Ha of advanced coastline. These significant changes are influenced by human activities and coastal environmental conditions. This research is expected to be the basis for spatial planning and disaster mitigation efforts in the coastal area of Ambon City.

Abstract

This study attempts to identify the procedure for annulling an arbitral award through the courts and the legal framework governing it. The author uses Gustav Radbruch's legal theory the theory of justice, legal certainty, and legal consequences as an instrument to examine and explain the mechanism for annulling an arbitral award, the types of legal remedies available, and their legal consequences. Using this approach, the author can assess whether an annulment request for an award can be submitted based on the grounds stipulated in law, as well as identify the legal steps that can be taken and their legal impact. The method used is normative legal research, which compiles legal sources by referring to norms in statutory regulations, court decisions, and social customs. The legal sources analyzed include primary materials authoritative documents such as laws, official records, legal treatises, and judicial decisions and secondary materials, namely non-official publications such as textbooks, legal dictionaries, journals, and commentaries on court decisions. Based on the findings, the author concludes that the arbitration award is final and binding on the parties. However, an annulment can be requested if the three conditions stipulated in Article 70 of Law Number 30 of 1999 concerning Arbitration and Alternative Dispute Resolution are met. Because it is a special civil case, there is no appeal to the High Court; the term "appeal" actually refers to cassation to the Supreme Court, which in Article 72 paragraph 4 is stated as the first and final legal remedy. According to Circular Letter Number 4 of 2016 concerning the Implementation of the Results of the 2016 Plenary Meeting of the Supreme Court Chamber as a guideline for the courts, if the District Court rejects the application for annulment of the arbitration award, no further legal remedies are available, either an appeal or a judicial review.

Abstract

Arabic maharah qira’ah learning for non-native speakers still faces obstacles in text comprehension due to limited vocabulary, the complexity of language structures, and the use of learning approaches that tend to be partial rather than integrative. This study aims to analyze integratively the application of bottom-up, top-down, and interactive reading theories in maharah qira’ah learning. This study uses a descriptive qualitative approach with the library research method. Data were obtained from various literature sources such as books, scientific journal articles, and relevant previous studies, then analyzed using content analysis techniques. The results of the study show that the bottom-up approach plays a role in the gradual recognition of language elements, while the top-down approach helps comprehension through background knowledge activities, and the interactive model integrates both simultaneously. The integration of these three approaches becomes more effective when applied in systematic learning stages, namely pre-reading, during-reading, and post-reading. Thus, the integration of reading theories can be a strategic solution in developing maharah qira’ah learning that is more comprehensive, systematic, and effective for non-native speakers.

Abstract

Smallholder dairy farming plays a crucial role in rural livelihoods and food security in developing countries, yet it is highly exposed to multidimensional risks that threaten its sustainability. While previous studies have examined agricultural risks and sustainability separately, limited attention has been given to how these risks interact to shape system resilience and adaptive capacity. This study aims to analyze resilience in smallholder dairy farming by integrating Enterprise Risk Management (ERM) with a multidimensional sustainability framework. A case study was conducted in Suci Village, Jember Regency, Indonesia, involving 30 respondents, including farmers, cooperative representatives, and agricultural officers. Data were collected through focus group discussions, semi-structured interviews, and field observations. Risks were identified and assessed using an ERM-based risk register matrix, evaluated through likelihood and impact scoring. The results were subsequently reinterpreted using a resilience framework, linking risk exposure, sensitivity, and adaptive capacity. The findings reveal that most risks are concentrated in the high and extreme categories, indicating a structurally vulnerable system with low baseline resilience. Risks are highly interconnected across ecological, economic, social, and technological dimensions, generating cascading effects that amplify system instability. Technological limitations and weak institutional capacity were identified as key constraints to adaptive capacity, further increasing vulnerability to recurring shocks. This study contributes to the literature by extending ERM from a risk classification tool into a resilience-oriented analytical framework. By integrating risk management with sustainability dimensions, the study provides a novel approach to understanding and strengthening resilience in smallholder agribusiness systems. The findings offer practical implications for developing integrated, context-specific strategies to enhance long-term sustainability and adaptive capacity in smallholder dairy farming.

Abstract

The condition of the subgrade soil on the Hukurila-Seri Ring Road section, Ambon City has the potential to experience a decrease in carrying capacity due to the abandonment of construction projects. To overcome these problems, efforts are made to improve the soil using the stabilization method using additional materials in the form of cement and clay soil. This study aims to determine the classification of soil at the location, as well as evaluate the effect of the addition of cement and clay soil on soil grain gradation and CBR (California Bearing Ratio) value. The test was carried out in the laboratory using native soil taken from the research site, then mixed with variations of cement (4%, 7%, and 10%) as well as a combination of optimum cement + clay soil (2%, 9%, and 24%). The results of the study showed that the addition of cement significantly increased the CBR value of the soil. The optimum mixture is obtained at the 10% cement variation which provides the highest increase in CBR value.

Abstract

The high generation of waste in Indonesia, especially in the city of Surakarta, as well as suboptimal management has the potential to cause environmental pollution and increase the risk of health problems, especially in vulnerable groups such as scavengers at the Putri Cempo Landfill. This study aims to determine the relationship between knowledge and personal hygiene behavior in scavengers at Putri Cempo Landfill Surakarta with an observational design and this cross sectional approach has been carried out in February 2026. The research population was 287 scavengers, with a sample of 162 respondents taken using the purposive sampling technique. The results were obtained through primary data collected using a questionnaire that has been tested for validity and reliability and equipped with observational data. Data analysis was carried out univariate and bivariate using the Chi-Square test with a significance level of p < 0.05. The results showed that in the group of scavengers with low knowledge, most (56.2%) had poor personal hygiene behavior, while in the group with high knowledge, the majority (66.3%) had good personal hygiene behavior. The results of the Chi-Square test found that there was a significant relationship between knowledge and personal hygiene behavior in scavengers at the Putri Cempo Landfill Surakarta (p = 0.007). The conclusion of the research is the need to educate the scavenger community to increase personal hygiene knowledge and maximize the provision of sanitation facilities around the landfill.

Abstract

The environmental conditions of the Landfill (TPA) of unhygienic waste are at high risk to the skin health of workers, especially scavengers who interact directly with waste every day. This study aims to analyze the relationship between personal hygiene and symptoms of skin diseases in scavengers at TPA Putri Cempo Surakarta. This research is an analytical  observational research design through a cross sectional approach that has been carried out in February 2026 at the Putri Cempo Surakarta Landfill located in Mojosongo Village, Surakarta. Sampling involved 162 respondents obtained from a population of 287 people at the Putri Cempo Landfill through the calculation of the Lemeshow formula and purposive sampling techniques. Primary data was collected through filling out questionnaires and direct observation. The results showed that 78 (80.4%) scavengers with poor personal hygiene had experienced skin diseases in the last six months. The results showed that there was a significant relationship between the incidence of skin diseases and personal hygiene supported by the chi-square test with a p value of 0.028 (p < 0.05). So it can be concluded that poor personal hygiene has an impact on the appearance of skin disease symptoms in scavengers at landfills. Good preventive measures and personal hygiene are the key to increasing the safety and productivity of scavengers.
