Abstract

The onshore transportation of heavy modules requires a reliable lashing securing system to prevent cargo shifting, which can lead to accidents and economic losses. This study evaluates the effectiveness of a lashing system used for transporting a heavy industrial component by land. A quantitative method was employed, comparing the total securing force provided by the lashing system against the sliding force induced by vehicle acceleration, braking, and cornering. Technical data on the lashing system, module specifications, and friction coefficients were obtained from field surveys and technical documents. The results show that the total securing force of the optimized lashing system is 2.49 MT, which exceeds the maximum sliding force of 1.87 MT under emergency braking conditions. The resulting safety ratio of 1.33 meets the minimum requirements of DNVGL-ST-N001 and the IMO CSS Code. A sensitivity analysis indicates that the lashing angle and contact surface friction coefficient are the most influential parameters. This study concludes that the evaluated lashing system is safe and applicable to similar transportation operations. Recommendations are provided regarding periodic inspections and optimization of lashing configurations.

Abstract

Digital platform capitalism has restructured market coordination through data extraction, algorithmic governance, network effects, and ecosystem integration. Contemporary competition law, grounded in the consumer welfare paradigm, evaluates market conduct primarily through price-based metrics that obscure structural asymmetries. This article addresses the gap between allocative efficiency and structural justice by developing Ethical Market Failure (EMF)—a structural extension of classical market failure theory capturing infrastructural concentration, dependency locking, and distributive asymmetry in platform dominated economies. Integrating digital competition scholarship with Islamic political economy, the study employs the Maqasid alShariah framework as a normative evaluative architecture. The classical institution of hisbah is reinterpreted as a governance logic informing regulatory oversight. Using Indonesia as a semi analytical empirical anchor, the article demonstrates how subsidy driven expansion, gig labor absorption, and ecosystem consolidation generate long-term structural distortions despite short-term consumer gains. This study contributes to platform governance debates by situating consumer welfare within a broader justice sensitive institutional hierarchy.

Abstract

Pemikiran ekonomi Islam pada konsep produksi untuk mengimbangi pemikiran ekonomi produksi konvensional yang mana dalam ekonomi Islam memandang ekonomi berada di tengah dan memperjuangkan keseimbangan yang adil di semua bidang ekonomi, termasuk keseimbangan antara bisnis dan modal, sehingga menghasilkan output yang seimbang antara pemilik pabrik dan pekerja serta output produk yang halalan toyibah dan berkah untuk konsumen, dan pemilik perusahaan serta memberikan dampak manfat untuk kelompok sosial. Metode penelitian dalam penelitian ini menggunakan metode kwalitatif dengan riset pada jurnal sebelumnya dengan meneliti road map dari hasil karya yang sudah ekisis. Hasil Penelitian bahwa  konsep  produksi secara Islam dengan system bagi hasil dan membayar upah pekerja sebelum kering keringatnya, menghasilkan produk yang halalan toyibah dan berkah serta menguntungkan. Penegasan ini dapat diterima jika perilaku prinsip Islam ini dikerjakan dengan komprehensip, terhadap sarana, prasarana, peralatan produksi, bahan produksi yang halal dan metode konsep produksi secara syari’, konsep distribusi dan konsumsi secara Islam, maka menghasilkan barang produksi yang bermanfaat dan berkeadilan dan seimbang.

Abstract

This paper presents the piping stress analysis of the XYZPlatform as part of the EPCI Contract for Platform Reactivation of the XYZ Project, operated by PT. XYZ. The analysis was conducted using CAESAR II Version 2019 (11.0) for piping system Model 03, covering the pipeline from Pig Receiver (R-002) to Upstream HIPPS (Z-010). The objective was to verify compliance with ASME B31.3 (2020) Process Piping code under various load cases including hydrotest, sustained, operating, occasional, and expansion conditions. Line properties analyzed involve 8-inch and 10-inch carbon steel pipes (A106 Grade B and API 5L X52) with design pressure up to 1,550 psi and design temperature of 200°F. Results demonstrate that all maximum stresses are within allowable limits, with sustained stress ratio reaching 60.8%, occasional stress ratio at 61.2%, and thermal expansion ratio at 23.0%. Maximum displacement in the operating condition is 9.013 mm in the X-axis direction, well within the 100 mm threshold. Flange leakage verification using the Pressure Equivalent Method yields a maximum ratio of 77.72%, confirming integrity. The minimum natural frequency of the piping system is 4.585 Hz, exceeding the required 4 Hz minimum. All equipment nozzle loads at the Pig Receiver are within allowable limits per CPY-SPE-0009. The study confirms that the proposed piping configuration for XYZPlatform is structurally sound and compliant with applicable codes and project specifications.
