Abstract

Implementation of government projects funded by the State Revenue and Expenditure Budget (APBN) still often faces legal uncertainty problems, particularly in the implementation of public construction contracts affected by price fluctuations, complex project risks, and suboptimal dispute resolution mechanisms. The principle of legal certainty—an essential foundation of public administration—has not been fully realized consistently in government goods and services procurement practices. This research uses a normative juridical method with a statutory and conceptual approach, aiming to formulate an adaptive contract model and a digital law governance framework relevant to the dynamics of state construction projects. The findings show the need to reformulate a more robust contract model that is responsive to changing conditions through the implementation of price adjustment clauses, proportional risk distribution, and the use of dispute boards as preventive dispute-resolution instruments. Moreover, the integration of digital systems such as SPSE (Electronic Procurement System), e-monitoring, and smart legal dashboards plays a significant role in strengthening data-based legal certainty and enhancing transparency in the procurement process. Based on these findings, the research recommends updating regulations and designing more adaptive construction contracts to support accountability, efficiency, and strengthen public trust in the implementation of national strategic projects.

Abstract

This study examines legal protection for service providers against unilateral contract termination by service users in the construction sector in Indonesia. This problem arises from the imbalance in the legal and economic positions between the parties, as well as weak legal regulations that provide room for broad interpretation for service users. This study uses a normative juridical method with a statutory, conceptual, case, and comparative legal approach. The analysis was conducted on the Civil Code (KUHPerdata), Law Number 2 of 2017 concerning Construction Services, and Presidential Regulation Number 16 of 2018, then compared with the legal systems of the European Union, China, and South Korea. The results of the study indicate that legal protection in Indonesia is still administrative and formalistic, not guaranteeing proportional contractual justice for service providers. Therefore, this study recommends a balanced contractual protection model, which emphasizes compensation obligations, the principle of good faith, and the establishment of an independent contract mediation institution as a solution towards a fair, transparent, and sustainable contractual legal system.

Abstract

The landscape of construction projects in Indonesia is becoming increasingly complex with the growing involvement of international funding and foreign contractors. The FIDIC Red Book 2017 has become the dominant global standard, while Indonesia operates under its own national construction law framework. This study aims to comparatively analyze the principles, mechanisms, and risk allocation in the FIDIC Red Book 2017 (Reprinted 2022) and the Indonesian national construction contract framework as reflected in the Construction Services Law and its derivative regulations. Using a normative literature study with a comparative law approach, the research identifies fundamental philosophical differences in risk management. FIDIC emphasizes fairness, balanced risk allocation, and structured procedural mechanisms (FIDIC, 2022; Soekotjo, 2019), whereas Indonesia’s national regulations tend to favor the Employer (government) with limited contractual flexibility (LKPP, 2021). The key findings lie in differences related to claim mechanisms, the role of the Engineer, and dispute resolution processes. This study contributes by providing a systematic comparative mapping useful for stakeholders—especially in hybrid international–national projects—and offers recommendations for harmonizing and improving contractual frameworks in Indonesian construction practice.

Abstract

Simultaneous general elections throughout Indonesia can have a substantial environmental impact. The primary environmental challenge, which repeatedly causes problems, is the inadequate management of waste from campaign props. Waste management for campaign materials has not been specifically regulated, leading to policy inconsistencies across regions. Currently, managing waste from campaign props falls under the responsibility of Regional Apparatus Organizations, which process it for reuse where possible. Waste that cannot be reused must not be disposed of in Final Disposal Sites (TPA). The limited number of landfills and waste recycling sites in each region is insufficient compared to the volume of campaign props used in simultaneous elections. The Province of Bali took the initiative to implement green elections from the initial planning stage through to the end of election implementation. The General Elections Commission (KPU) urged contestants' campaigns to avoid plastic billboards, promoting social media and non-plastic alternatives instead. This green election initiative was realized through policies enacted by the Regional Government, including the Governor's Regulation on reducing plastic waste. It exemplifies cross-sector collaboration as a strategy to mitigate the ecological impact of election implementation. This study analyzes collaborative efforts and proposes policy recommendations for realizing green elections in Indonesia. This research employs a qualitative method with an empirical juridical approach, focusing on the implementation of green elections in Bali Province during the 2024 Regional Elections.

Abstract

The landslide incident on the Karo Regency Boundary Road – Panji STA 26+000, North Sumatra Province, showed a decrease in slope stability as indicated by a safety factor (sf) value of less than 1.00. This study aims to analyze the causes of slope instability influenced by the cracked soil phenomenon and heavy rain. The slope stability analysis research method was carried out using Geo5 software based on the limit equilibrium method. The simulation results with the Geo5 application on the original soil conditions showed a safety factor (sf) value of 2.10 which indicated that the slope was in a safe and stable condition. However, after the cracked soil parameters and heavy rain intensity were entered into the Geo5 application, the analysis results showed a drastic decrease in the safety factor (sf) value to 0.93 which indicated that the slope was in an unsafe condition or a landslide. The cracked soil phenomenon increased the infiltration path of rainwater which then accelerated the increase in pore water pressure and weakened the shear strength of the soil, causing landslides.

Abstract

This study explores how communal solidarity and familial bonds function as forms of social capital that strengthen catechetical ministry in rural Catholic communities, drawing evidence from the pastoral reality of Stasi Rondo Woing. Although the community faces persistent challenges—such as limited catechist formation, low participation, and geographical constraints—the research reveals that deeply rooted cultural values of mutual cooperation, kinship, and shared responsibility provide a powerful foundation for revitalizing faith formation. Using a qualitative approach involving interviews, observations, and documentation, the study shows that these social capital dimensions significantly shape how catechesis is received, practiced, and sustained. Communal solidarity encourages collective engagement in catechetical gatherings, while family-based relational networks foster intergenerational transmission of faith and leadership emergence within small Christian communities. When catechesis is integrated into these relational and cultural structures, it becomes more relevant, participatory, and transformative, enabling the community to take active ownership of its spiritual development. This study concludes that leveraging communal and familial social capital is essential for building resilient and empowered catechetical ministries in rural settings, offering a model that aligns with contextual pastoral approaches and supports long-term ecclesial vitality.

Abstract

The Business Judgment Rule (BJR) is a corporate law principle that provides protection to directors for business decisions taken in good faith, prudence, and orientation to the interests of the company. This concept becomes important when the directors' decisions result in losses or alleged criminal acts, as occurred in the case of the acquisition of PT Jalan Nusantara (JNT) by PT ASDP Indonesia Ferry (Persero) which involved three former directors of the company. The problem is how the Business Judgment Rule (BJR) can provide legal protection to directors in the strategic decision-making process, as well as assessing the limitations and exceptions to its application if there are indications of abuse of authority, serious negligence, or conflicts of interest. By using a normative juridical approach and analysis of court decisions, laws and regulations, and corporate law literature, this study shows that the application of the Business Judgment Rule (BJR) requires proof that the directors acted in accordance with fiduciary duty standards, including the duty of care and duty of loyalty. The research findings confirm that the Business Judgment Rule (BJR) cannot be used as a shield if acquisition decisions are made without adequate feasibility studies, deviate from corporate procedures, or carry the potential for state losses. Therefore, this contribution contributes to understanding the limits of legal protection for state-owned enterprise directors and its legal implications for corporate decision-making practices in Indonesia.

Abstract

The construction of the Serang – Panimbang Toll Road Section III faces the challenge of surplus excavated material dominated by clay shale from the Bojong Formation. This material is categorized as highly plastic clay (CH) with high swelling and shrinkage potential, so it does not meet the specifications as fill material without special treatment. This study aims to evaluate the effectiveness of stabilizing the excavated soil using calcium carbonate (CaCO3)-based lime. The research method was conducted experimentally in the laboratory with variations in lime content additions of 6%, 7%, and 8% to the dry weight of the soil. The tests included physical properties (Atterberg Limits, Specific Gravity) and mechanical properties (Standard Proctor, CBR Soaked, Unconfined Compressive Strength/UCS, and Swelling). The results showed that the original soil had a Plasticity Index (PI) of 61.17% and a very high swelling potential of 6.92%. Stabilization with CaCO3 proved to be effective in improving soil characteristics. The most optimal decrease in PI occurred at a variation of 7% (to 47.63%), but the best improvement in mechanical properties was achieved at a variation of 6%. At a 6% concentration, the soaked CBR value increased from 0.498% to 1.549%, the unconfined compressive strength (qu) increased to 2.681 kg/cm², and the swelling potential decreased dramatically to 1.26%. Thus, a 6% addition concentration is recommended as the optimum variation for soil stabilization at the study site.

Abstract

Infrastructure damage on the Aruk – Sp. Take Road Section, Sambas Regency (especially STA 99+000 to STA 99+550), is directly attributed to soft soil conditions characterized by low bearing capacity and high compressibility. Previous conventional repair methods were deemed ineffective, while permanent solutions involving Pile Slabs proved to be financially prohibitive for extensive road segments. This study aims to analyze the effectiveness of combining a lightweight fill material (Foam Mortar) with consolidation acceleration using Prefabricated Vertical Drains (PVD) on key geotechnical parameters: settlement, consolidation time, and slope stability. The methodology comprises soil data analysis, modeling of embankment designs with varying Foam Mortar compositions (0%, 25%, and 50%) at different heights, and consolidation calculations using a triangular PVD pattern. The analysis results demonstrate that installing PVD at an optimal spacing of 1.25 meters achieved a degree of consolidation of 91.2% within 22 weeks. Furthermore, the inclusion of Foam Mortar was proven significant in reducing the overall load and substantially improving stability. In the final height design of 3.30 meters, the 50% Foam Mortar variation reduced the maximum settlement to 1.38 meters (compared to 1.70 meters on 100% conventional earthfill) and drastically increased the Safety Factor (SF) from 1.90 to 3.06.

Abstract

Differential settlement in the transition zone between embankment segments and rigid structures such as Slab-on-Pile is one of the most critical issues in toll road construction on soft soil, as it may reduce ride comfort, safety, and service life. In the Serang–Panimbang Toll Road Section III Project, the applied ground treatment method consists of Free Draining Granular Material (FDGM) supporting the approach embankment and bored piles as the abutment foundation for the Slab-on-Pile system. This study aims to evaluate the performance of the existing treatment method by comparing settlement predictions derived from one-dimensional analytical methods (Terzaghi’s theory for embankments and the Boussinesq and Poulos–Davis methods for abutments) with two-dimensional numerical modeling using PLAXIS. The resulting settlement profile in the transition zone is then analyzed to assess the potential for differential settlement with respect to the applicable serviceability limits. The validation results show a strong agreement between analytical and numerical methods, with settlement deviations of 6.09% for the embankment and 4.93% for the abutment. Nevertheless, the embankment over FDGM experiences a total settlement of 51.90 cm, while the Slab-on-Pile abutment settles only 6.10 cm, producing a differential settlement of 45.80 cm, far exceeding the allowable limit. These findings indicate that the use of FDGM alone is insufficient to accommodate the high compressibility of the thick soft soil deposit at the study location.
