Abstract

Utilizing waste as an alternative building material is becoming an effective solution to environmental problems and is popular in developing countries. On the other hand, the concrete industry, a key component of construction, continues to innovate to improve quality and efficiency. The increasing demand for concrete is driving the development of mix designs that meet stringent quality and compressive strength standards, while taking into account environmental sustainability. Advances in concrete technology spur research initiatives to improve its quality and efficiency of use, with innovations in material selection and execution methodologies. This is aimed at meeting the increasing needs and overcoming construction challenges. Modern concrete is required to perform optimally in less time, requiring effective additives for performance enhancement. Recent research has integrated bamboo waste from the handicraft industry as a component of concrete mixes, increasing the speed of project execution and providing a sustainable solution in waste management. The authors were interested in conducting an in-depth study on increasing the compressive strength of concrete by integrating waste bamboo pieces. The concrete under study has the following grades f´c 25 MPa (K-300) and tested at 7, 14, and 28 days to assess the effectiveness of bamboo as an additive. The test results are expected to provide significant data on the viability of bamboo waste as a partial substitution for coarse aggregate. The title of the study, “Use of Waste Bamboo Pieces as Partial Substitution for Coarse Aggregate to Increase the Compressive Strength of Concrete,” reflects the objectives of the study and the utilization of sustainable materials in modern construction. Based on the results of the research that has been carried out and the discussion in the previous chapter with the variation of waste bamboo pieces 0%, 10% and 15%, the conclusions can be drawn, namely as follows the results of compressive strength testing on normal concrete at the age of 28 days reach 452 kN (fʹc 26,1 MPa = 104%), while variation 1 of 10% waste bamboo cuttings experienced a decrease in compressive strength, reaching 305 kN (fʹc 17,60 MPa = 70%), and variation 2 15% waste bamboo cuttings decreased, reaching 309 kN (fʹc 17.83 MPa = 71%).

Abstract

Concrete is a primary construction material consisting of a mixture of cement, water, sand, and aggregate, and often includes additives to improve specific properties such as workability, durability, and setting time (McCormac, 2004). Bamboo fibers, which have a compressive strength of 45.4 MPa (Afdal, 2016) and contain hydroxyapatite (HA), are used as an additive in concrete to improve performance. This study tested the compressive strength of normal concrete and concrete with bamboo fiber variations of 2%, 4%, and 6% at ages of 7, 14, and 28 days, each with two samples per variation (total of 24 test specimens). The test results showed that at 7 days, the 6% variation exhibited the highest compressive strength increase (20.42 MPa) compared to normal concrete (16.37 MPa). However, at 14 and 28 days, only the 6% variation again showed an increase in compressive strength (22.64 MPa), while the 2% and 4% variations tended to decrease compared to normal concrete.

Abstract

Road construction on soft soils presents significant technical challenges due to the natural properties of the soil such as low bearing capacity, high compressibility and limited shear strength. This study aims to analyze the response of soft clay soil to vertical loads under varying water infiltration conditions using numerical modeling with PLAXIS 2D software. Modeling was performed at a laboratory scale of 1:20 with a soft soil thickness of 57 cm and a 3 cm thick flexible pavement layer. Simulations were conducted under three water addition scenarios: 19%, 36%, and 53%, each with a waiting period of 3 days before a load of 20.4 kg was applied. The simulation results showed that increasing the water content significantly affected the soil deformation (displacement), with vertical settlement values of 0.06128 mm, 0.1342 mm, and 1.039 mm for the 19%, 36%, and 53% scenarios, respectively. Meanwhile, the effective stress values also experienced a limited increase, namely 10.17 kN/m², 11.39 kN/m², and 11.41 kN/m². This finding indicates that although the effective stress increases numerically, saturated conditions due to high infiltration can actually decrease the overall stability of the soil.

Abstract

Kepailitan merupakan suatu kondisi di mana debitor tidak dapat memenuhi kewajiban finansialnya, yang berujung pada proses hukum untuk penyelesaian utang. Penelitian ini bertujuan untuk mengkaji perspektif hukum terhadap kepailitan pada dua jenis badan usaha, yakni Perseroan Terbatas (PT) dan Persekutuan Firma. Kedua badan usaha ini memiliki karakteristik hukum yang berbeda, yang mempengaruhi mekanisme penyelesaian kepailitan dan dampaknya terhadap kreditor serta pemegang saham atau anggota. Dalam konteks PT, terdapat pembatasan tanggung jawab pemegang saham terhadap utang perusahaan, sementara dalam Persekutuan Firma, anggota persekutuan memiliki tanggung jawab penuh terhadap kewajiban bisnis, baik secara pribadi maupun bersama. Penelitian ini menggunakan pendekatan normatif dengan analisis terhadap undang-undang yang relevan, serta literatur yang berkaitan dengan kepailitan dan hukum perusahaan. Hasil penelitian menunjukkan bahwa meskipun ada perbedaan mendasar dalam pengaturan tanggung jawab hukum antara PT dan Firma, keduanya memiliki mekanisme yang bertujuan untuk memberikan perlindungan bagi kreditor sekaligus memastikan kelangsungan usaha. Oleh karena itu, pemahaman yang mendalam mengenai perbedaan dan persamaan dalam pengaturan kepailitan kedua badan usaha ini sangat penting bagi pengusaha, praktisi hukum, serta pihak-pihak terkait dalam upaya mengelola risiko hukum yang mungkin timbul.
