Abstract

This research analyzes contractual challenges arising from the Owner's involvement in engineering drawing approvals within Engineering, Procurement, and Construction (EPC) contracts, using the 500 kV Sumatra Transmission Project as a case study. Under the FIDIC Silver Book, the contractor bears full responsibility for engineering, procurement, and construction; however, PT PLN (Persero)'s review and approval of drawings introduced legal ambiguity and contributed to delays that led to Extension of Time (EOT) claims. Using a normative legal research method, the study shows that delays caused by Owner-initiated revisions constitute a valid basis for EOT under Sub-Clause 8.4, provided claims are submitted timely and supported by evidence. Conversely, procedural non-compliance may classify such delays as contractor default, subjecting the contractor to liquidated damages. The research concludes that Indonesia's civil law framework has not fully integrated FIDIC Silver Book principles, particularly regarding EOT processes, risk allocation, and dispute resolution. The study recommends standardizing EPC governance and clarifying Owner involvement.

Abstract

Highway construction in Indonesia frequently encounters geotechnical problems due to soft soil conditions. The combination of pile slab construction and road embankments, which are commonly found on highways, has the potential for subsidence in the long term if 90% consolidation has not been achieved or primary settlement of the embankment has not been completed. This has the potential to disrupt the safety and serviceability of road users and cause delays in construction completion. Soft soil conditions, as found on the Patimban Subang Access Toll Road, have an NSPT value ?10 to a depth of 10 meters. This study aims to analyze the settlement of embankments using replacement and without replacement at the junction of the embankment segment and pile slab. By using a 1.5 m replacement in soft soil layers using the Terzaghi method, the cumulative settlement was 87.17 cm, while Plaxis 2D modeling showed a settlement of 93.90 cm. On the other hand, manual calculations without using replacement showed a cumulative settlement of 120.27 cm.

Abstract

The involvement of foreign companies in infrastructure development in Indonesia has increased rapidly over the last two decades, driven by growing needs for capital, technology, and advanced project management standards. However, the complexity of cross-jurisdictional issues and divergent interests among states, state-owned enterprises, investors, and contractors heightens the potential for intense legal disputes. This research examines the characteristics of disputes, their root causes, national and international regulatory frameworks, dispute resolution mechanisms, case patterns, and recommendations for strengthening project governance. Studies show that dispute roots extend beyond technical-contractual matters to include political factors, regulatory disharmony, information asymmetries, and weak contract administration. The research concludes that preventing disputes through appropriate risk allocation, regulatory transparency, and enhanced government capacity represents fundamental steps to mitigate the economic and political costs of high-value infrastructure disputes. The findings imply that, to enhance Indonesia’s attractiveness to foreign investors, policymakers should prioritize regulatory harmonization, institutionalize early dispute prevention mechanisms such as the Dispute Avoidance/Adjudication Board (DAAB), and streamline enforcement of international arbitration awards.

Abstract

This research analyzes the adaptation strategies of three multinational automotive companies in Indonesia—namely Toyota Motor Manufacturing Indonesia (TMMIN), PT Astra International Tbk., and PT Indomobil Sukses Internasional Tbk.—in responding to the dynamics of the global business environment through the perspective of Dynamic Capability Theory. The focus of the study is directed toward the three components of capability according to the theory: adaptive capability, absorptive capability, and innovative capability, which serve as the basis for evaluating the companies' ability to make strategic adjustments amid rapid changes triggered by globalization, geopolitical tensions, supply chain disruptions, workforce transformation, acceleration of digitalization, and increased global investment in low-emission vehicle technology. The results of the study show that the three companies practice different but complementary adaptation strategies. TMMIN develops the most systemic strategies through electrification, export strengthening, green manufacturing, technology transfer, and triple helix collaboration. Astra's strategy focuses on digital transformation, ecosystem synergy, technology investment, and strengthening corporate sustainability. Indomobil's adaptation strategy focuses on exploiting market knowledge, global brand collaboration, and resilient segments. The synthesis of these three strategies results in an adaptation framework that overcomes the negative impacts of global dynamics, such as supply chain disruptions, skilled labor shortages, technology gaps, and digitalization pressures. This research makes a theoretical contribution to the development of the International Business Management literature, especially in understanding the contextual application of dynamic capability in the Indonesian automotive industry.

Abstract

The construction of the Betung (SP Sekayu) – Tempino – Jambi Trans Sumatra Toll Road Section 1B, particularly at STA 55+900, faces significant geotechnical challenges due to soft subgrade in the floodplain area. Geotechnical investigations indicate that the surface layer up to a depth of 4.45 meters is dominated by very soft silty clay with an N-SPT value of 2-4, which risks triggering embankment instability and excessive settlement in the planned 6.6-meter high embankment. This study aims to analyze the effectiveness of lightweight fill material in the form of foam mortar as a substitute for conventional embankment materials. Numerical analysis based on the finite element method (Plaxis 2D) was carried out by modeling variations in foam mortar thickness of 25%, 50%, and 75% of the embankment height. The simulation results show that the use of lightweight materials effectively increases stability and reduces settlement. The most optimal design configuration was obtained at a substitution variation of 75% foam mortar, which resulted in a Safety Factor (SF) value of 2.727. This value indicates an 58.64% increase in stability compared to conventional soil embankments and is capable of reducing total settlement by up to 25.26% (by 9.745 cm). These findings recommend foam mortar as an alternative solution that meets the technical criteria for stability and deformation.

Abstract

This study discusses the settlement and lateral displacement of piles on a toll road built on saturated soft soil in a coastal area. The case study focuses on the point where the off-ramp and main road meet, with soil conditions dominated by very soft clay to a depth of ±58 m (N-SPT <10), meaning the piles function primarily as friction piles. Soil data from the BH-03 drill were processed through N-SPT correction, consistency grouping, and compressibility parameter correlation to obtain input for numerical modeling. The modeling was done using PLAXIS 2D under plane strain conditions, with the Soft Soil model for clay and Mohr–Coulomb for non-cohesive soil. Construction stages included 2.5 m of backfilling, two years of consolidation, and the installation of new piles near existing piles. The results showed that the vertical settlement of the pile tip from the numerical model was 3.9 cm, closely matching the analytical calculation results (3.07–3.66 cm), which is still within the SNI 8460 serviceability criteria. However, the lateral displacement reached 5–5.7 cm, exceeding the SNI limit of <2.5 cm. Horizontal displacement contours revealed a 6.3–10.1 cm soil shift toward the outside of the slope during new pile construction, indicating that long-term consolidation, embankment slope geometry, and seabed slope are the main causes of lateral deformation.

Abstract

The construction of the Patimban Port Access Toll Road faces significant geotechnical challenges due to the presence of thick soft soil layers characterized by low bearing capacity and high compressibility. Conventional soil embankments constructed on such ground conditions may induce excessive settlement and require a long consolidation period. This study aims to evaluate the effectiveness of Expanded Polystyrene (EPS) Geofoam as an alternative lightweight embankment material through numerical analysis using PLAXIS 2D. Four embankment configurations were analyzed: conventional embankment with initial preloading and composite embankments incorporating EPS Geofoam with thicknesses of 1 m, 2 m, and 3 m. The evaluation parameters include vertical settlement magnitude, consolidation time, and deformation patterns at key observation points, namely the center line, embankment toe, and critical settlement point beneath the embankment. The results indicate that the application of EPS Geofoam significantly reduces vertical settlement compared to the conventional embankment. Settlement reduction exceeding 85% was achieved for Geofoam thicknesses of 2 m and 3 m, accompanied by accelerated consolidation stabilization within less than 140 days. Increasing Geofoam thickness effectively reduces settlement but may induce uplift at the embankment toe due to lateral stress redistribution. Overall, EPS Geofoam with a thickness of 2–3 m provides the most optimal performance in controlling settlement and accelerating soil stabilization, making it a viable lightweight embankment solution for toll road construction on soft soil, particularly in coastal areas such as Patimban.

Abstract

ile foundations are a common solution on soft soils with low bearing capacity. However, new construction activity near existing structures has the potential to trigger pile displacement or settlement. This study aims to analyze the performance of existing slab-on-pile foundations at study sites with soft soil up to a depth of 70 m, where the distance between the new foundation and the existing foundation is relatively small. The analysis was carried out through theoretical calculations (Meyerhof and Poulos-Davis methods) and gradual numerical modeling using PLAXIS 2D. The results of axial calculations show an ultimate capacity of kN. The numerical results indicate that the axial force in the existing piles has decreased. Vertical deformation ( ) increases from 3.4 cm to 5.96 cm in the structural phase. The increase in external load causes horizontal deformation ( ) in the backfill phase to reach 29 mm, exceeding the service limit of 25 mm; this lateral deformation then reduces to 18.9 mm in the final phase. In addition, the bending moment in the piles shows a significant increase from 11.18 kNm to 96.82 kNm, indicating the dominance of additional load and changes in soil conditions on the bending response of the piles. These results emphasize the importance of comprehensively evaluating soil-structure interactions under soft soil conditions and narrow distances between foundations.

Abstract

This research aims to develop and apply lyrics of poetry with the theme of Iman, Islam, and Ihsan as a medium for character learning in the university environment. This development model departs from the need for religious media that is touching, easy to remember, and in harmony with Islamic values. The method used is research and development according to Sugiyono (2019) with the stages of needs analysis, design, expert validation, and limited implementation. The results of the study show that the lyrics of the verses developed have a strong spiritual and emotional touch, helping students understand the basic concepts of Islam through aesthetic language. The application of these poems increases religious awareness, worship discipline, and social empathy of students. Thus, Islamic poetry can function as a medium for internalizing the values of faith, Islam, and ihsan in the context of character education in higher education.
