Abstract

This study was conducted at STA 14+675 of the Bululawang–Sidomulyo–Tambakrejo road construction project, there was a landslide on the excavation slope with an initial geometry of 4V:1H and a height of about 10 meters. This study aims to identify the factors that cause landslides and evaluate effective treatment alternatives. The research method uses a quantitative descriptive approach supported by finite element method (FEM) based numerical analysis through PLAXIS 3D software. The soil characteristics were obtained from bore log data, soil laboratory tests, and geoelectric surveys and then compiled into a stratigraphic model for modelling. The results of the analysis showed that the increase in groundwater level had a significant effect on the reduction of slope safety factors due to increased pore pressure and decrease in effective stress of soil. The existing condition has a safety factor of 1.498 and reaches unstable conditions when the groundwater level rises to an elevation of +20.5 meters with an SF value of 0.980. Based on the results of the modelling variation slope stabilization, regrading the slope ratio to 1V:1H indicates the most stable slope condition (SF>1.5). Evaluation of slope stabilization show that regrading the first bench to 1V:1H and maintaining a steep slope 4V:1H  in the second bench provides the most cost-effectives solution with unit cost IDR 35,685,000.00 m3/m and safety factor of 1,512. However, regrading both the first and second benches to 1V:1H resulted in a higher SF value of 1.782 but required approximately 15% more land compared previous modelling variation The most stable slope stabilization conditions was obtained by regrading the first bench to 1V:1H combined with a soil retaining wall structure on the second bench resulted an SF value of 2.053 with the highest unit price implication of IDR 52,576,000.00 m3/m

Abstract

Retention is a mechanism for withholding part of payments in construction contracts that is used to ensure the fulfillment of work maintenance obligations. In practice, retention often raises disputes, especially regarding late payments, detention without legitimate reasons, or unclear terms for release of retention. This study analyzes the legal position of retention, the legal basis that requires its payment, and the implications of default when retention is still withheld after the work is declared completed through the Final Hand Over (FHO). The research uses a literature study method on the Civil Code, the Construction Services Law, the FIDIC Red Book, procurement document standards, and contract law literature. The results of the study show that retention is a legal part of a contractual agreement that is subject to the principle of pacta sunt servanda based on Article 1338 of the Civil Code. Retention detention without a legal basis after the issuance of the FHO constitutes a default, which results in the obligation to pay retention along with compensation in accordance with Article 1243 of the Civil Code. The research concludes that the retention payment is an absolute obligation that must be fulfilled and its violation entitles the Contractor to demand performance and compensation.

Abstract

The construction of the Southern Cross Line (JLS) in East Java Province is part of the National Strategic Project which aims to reduce the disparity between the northern and southern regions of Java Island. In STA 17 + 850 of the Bululawang–Sidomulyo–Tambakrejo section, the excavated slope of ±30 m high composed of limestone rocks experienced two landslides in the same segment (slope 2 and slope 3), although slope geometry has been improved through regrading from a slope of 71.6° to 45°. This study aims to analyze the main causes of landslides at the location using the cracked soil approach, as well as evaluate the effect of slope slope on the safety factor (SF) value. The concept of cracked soil refers to the existence of cracks, it can be in the form of fine cracks that are not visible visually or wide cracks, these cracks can function as rainwater infiltration pathways that can trigger collapse. The soil condition on the slope is modeled as a "behaving like sand" material with a "drained" condition (c = 0 and ? = ?). The analysis method was carried out using the Finite Element Method (FEM) with the Plaxis 2D auxiliary program through two main models. Model 1 models the soil material to be "behaving like sand" (c = 0 and ? = ?), so that the collapse is completely controlled by the inner shear angle in the absence of cohesion. Model 2 includes a polygon such as ground cracks placed on or near a slip plane, thus facilitating a specific c = 0 on that plane with variations in the width and depth of the cracks. Stability analysis at the initial conditions (after excavation) showed an SF value of >> 1, which did not yet represent the landslide conditions in the field. Through the cracked soil approach, an SF value of < 1 was obtained for both slope slope variations, both in model 1 and model 2. These results show that the cracked soil approach can be applied to explain the mechanism of landslides on the slope of STA 17 + 850 of the Bululawang-Sidomulyo-Tambakrejo Section.

Abstract

Porang is a leading commodity with export potential that is widely cultivated in Madiun District. The success story of farmers in cultivating porang led to the inauguration of the Pusat Pelatihan Pertanian dan Perdesaan Swadaya (P4S) Porang Kepel in Kare Subdistrict to support efforts to develop and sustain porang farming in Madiun District. The purpose of this study was to understand the role of P4S Porang Kepel in providing training that influences farmers' internal characteristics and the sustainability of porang farming through an approach using path analysis. This research employs a quantitative approach using path analysis with Structural Equation Modeling (SEM) to examine the relationships between P4S roles (as a learning group, facilitator, and consultant) and the three dimensions of farming sustainability: economic, physical environmental, and social. The role of P4S Porang Kepel as a study group has a direct negative influence on the physical environment aspects of sustainability and a negative indirect effect on the economic and social aspects, with the physical environment as an intervening variable. In contrast, the role of P4S Porang Kepel has a positive indirect effect on the social aspect of sustainability through the intervening variable of attitude toward porang farming. These different types of influence stem from the role of P4S as a study group, along with information from traders, which created cognitive dissonance for farmers in assessing the sustainability of porang farming.

Abstract

This article provides a comprehensive analysis of the binding force of procurement contracts within the framework of Article 1338 of the Indonesian Civil Code (KUH Perdata), which establishes that any legally executed agreement shall bind the parties with the force of law (pacta sunt servanda). Using a literature-based methodology, this study examines national regulations (the Indonesian Civil Code, public procurement legislation, Presidential Regulation No. 16/2018 and its amendments), legal doctrines of contract law and administrative law, as well as relevant judicial decisions. The findings show that procurement contracts possess a dual legal nature: they are private agreements governed by civil law while simultaneously being influenced by public law due to the state’s involvement and the use of public financial resources. As a result, their binding force is determined not only by compliance with the legal conditions for contract validity (Article 1320 of the Civil Code) but also by adherence to principles of transparency, accountability, efficiency, and regulatory conformity in public procurement. The study reveals that the application of Article 1338 to procurement contracts must consider: (1) the limits of freedom of contract, (2) standardized government procurement documents, (3) safeguards against abuse of power, and (4) dispute-resolution mechanisms such as objections, mediation, arbitration, or litigation. This article concludes that the binding nature of procurement contracts is not absolute; rather, it is contextual and conditioned by principles of good governance and public financial accountability. The study contributes to the development of procurement contract doctrine within the Indonesian legal system.

Abstract

This research investigates the implementation of the principle of equality in force majeure clauses under Indonesian government construction standard contracts, namely those regulated by the General Conditions of Contract (SSUK). The research is based on the idea that the risk-sharing in public construction contracts is still not fair. Contracting authorities (PPK) have most of the ability to interpret the contracts, while contractors have very few options when it comes to negotiating the conditions. A normative legal method was used, which included legislative, conceptual, and case methods. The examination encompasses the Indonesian Civil Code, the Construction Services Law, the Ministry of Public Works and Housing Regulation No. 14 /2020, and foreign standards such as FIDIC. The study identified seven structural imbalances in force majeure provisions: (1) outdated risk definitions unsuitable for modern challenges like pandemics and cyber-attacks, (2) rigid and ambiguous notification procedures that disadvantage contractors, (3) disproportionate time extension calculations ignoring chain effects, (4) absence of cost compensation mechanisms for uncontrollable risks, (5) unilateral interpretation authority vested in PPK without independent review, (6) lack of transparent risk allocation matrices, and (7) slow and ineffective dispute resolution mechanisms. These findings were confirmed through Supreme Court Decision No. 2241 K/Pdt/2020, which nullified contractor sanctions for flooding-related delays. The study recommends adopting adaptive risk definitions, establishing reasonable notification procedures (28-day standard), implementing cost compensation mechanisms, creating independent adjudication bodies, developing explicit risk allocation matrices, and streamlining dispute resolution processes to achieve contractual balance and good faith principles.

Abstract

This study examines the application of the principle of good faith in Indonesian construction contracts, highlighting the challenges it faces due to the technical complexity, high uncertainty, and financial risks inherent in construction projects. While the principle is affirmed in Article 1338 paragraph (3) of the Civil Code, its practical application remains unclear, often leading to disputes over delays, compensation claims, and unclear obligations. In modern construction contracts, particularly those based on international standards like FIDIC, good faith is emphasized as an operational principle, with dispute resolution mechanisms like Dispute Adjudication Boards supporting collaboration and early dispute resolution. However, empirical studies show that these boards are sometimes used for strategic delays and selective disclosures, highlighting the tension between theoretical principles and practical behavior. The study also explores how digitalization, through technologies like Building Information Modeling, audit logs, and blockchain, transforms project monitoring and verification, offering opportunities to redefine good faith as an objective, verifiable principle. This research aims to assess the role of good faith in construction contracts, dispute boards, and digitalization, providing insights into how digital tools can help objectify and enforce good faith in Indonesian construction practices.

Abstract

The construction of the Trans Sumatra Toll Road (JTTS) Betung – Jambi Section 1B faces challenges due to highly compressible soft soil conditions, which have the potential to cause excessive settlement and embankment stability problems. This study aims to optimize embankment management at STA 43+225 – 43+375 which was initially a 2m replacement by evaluating the effectiveness of Modified Chicken Foot (CAM), combined with variations in replacement depth from 0 to 2 m. The analysis was carried out using the finite element method with the PLAXIS 2D assisted program to compare the performance of consolidation settlement and safety factor ( SF ). The results showed that the application of CAM provided a delay effect ( delaytime ) on the initial settlement rate and significantly reduced the total settlement. The combination of Replacement 2 m + CAM showed optimal performance, suppressing the settlement of 5 m embankment to 0.811 m (reduced by 17% from the alternative without CAM. In addition, the application of CAM was proven to improve stability, with the highest SF value reaching 2,055 on a 3 m embankment without replacement.

Abstract

Soft ground with low bearing capacity and high compressibility is the main cause of embankment damage on the Aruk–Sp. Take road section, West Kalimantan. This research aims to evaluate the effectiveness of Encapsulated Stone Columns (ESC) as an alternative ground improvement method to increase the bearing capacity and stability of the embankment. The analysis was conducted using secondary soil data (SPT) from the most critical location (BH.04). Column geometry variations were modeled with diameters (D) of 0.7 m, 0.8 m, and 0.9 m, as well as varying distances between columns (s), to obtain an optimal design configuration. Bearing capacity was analyzed using Terzaghi's method, while embankment stability was analyzed using the Geo5 program. The results show that the bearing capacity of the foundation is a more critical design criterion than global slope stability. The ESC model with a low area replacement ratio (As < 0.19) maintains slope stability (SF > 1.5) but fails to withstand the planned embankment load of 330 kPa. Increasing the As value—through diameter enlargement or reduced column spacing—significantly improves the safety factor. The recommended geometry configuration (As ? 0.19) is safe for both bearing capacity and embankment stability under collapse conditions.

Abstract

This study addresses the persistent issue of construction project delays in Indonesia, proposing information technology (IT) adoption and strategic partnerships as key solutions to enhance project performance. Despite substantial infrastructure investment through the Proyek Strategis Nasional (PSN) program, construction delays remain a critical challenge, which cause cost overruns and suboptimal development outcomes. The research objective is to examine how IT adoption and strategic partnerships influence project performance, both directly and indirectly through supply chain integration, within state-owned construction enterprises (BUMN). The study employed a quantitative approach using questionnaires distributed through purposive sampling to 160 managers in five major construction BUMNs, followed by instrument testing using Smart PLS 4.1.1.4 software, including Outer Model Test, Inner Model Test, General Bias Test, and Hypothesis Test. The results demonstrate that: (a) Information Technology Adoption positively and significantly affects Supply Chain Integration ( -value = 4.592, -value = 0.000); (b) Strategic Partnership positively and significantly affects Supply Chain Integration ( -value = 6.501, -value = 0.000); (c) Information Technology Adoption positively and significantly affects Project Performance ( -value = 3.662, -value = 0.000); (d) Strategic Partnership has a negative and insignificant effect on Project Performance ( -value = 0.561, -value = 0.575); (e) Supply Chain Integration positively and significantly affects Project Performance ( -value = 5.379, -value = 0.000). The mediation analysis reveals that Supply Chain Integration serves as a critical mediating mechanism through which both IT adoption and strategic partnerships indirectly enhance project performance. These findings contribute to supply chain management theory by demonstrating that technological and relational capabilities must be integrated through supply chain processes to achieve optimal project outcomes.
