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.

Abstract

The use of waste as an alternative building material is 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 has driven the development of mix designs that meet strict quality and compressive strength standards, while also considering environmental sustainability. Advancements in concrete technology are driving research initiatives to improve the quality and efficiency of its use, with innovations in material selection and implementation methodologies. This aims to meet increasing demands and address construction challenges. Modern concrete is required to perform optimally in shorter timeframes, necessitating effective additives for performance enhancement. Recent research has integrated bamboo waste from the craft industry as a concrete mixture component, accelerating project implementation and providing a sustainable solution for waste management. The author is interested in conducting an in-depth study on increasing the compressive strength of concrete by integrating bamboo waste. The concrete studied has a quality of f´c 25 MPa (K-300) and was 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 substitute for coarse aggregate. The study title, “The Use of Bamboo Waste as a Partial Substitute for Coarse Aggregate to Enhance Concrete Compressive Strength,” reflects the research objectives and the utilization of sustainable materials in modern construction. Based on the results of the research conducted and the discussion in the previous chapter with variations of black bamboo waste at 0%, 10%, and 15%, the following conclusions can be drawn: the compressive strength test results for normal concrete at 28 days reached 452 kN (fʹc 26.1 MPa = 104%), while variation 1 with 10% black bamboo waste showed a decrease in compressive strength, reaching 305 kN (fʹc 17.60 MPa = 70%), and variation 2 with 15% black bamboo waste also showed a decrease, reaching 309 kN (fʹc 17.83 MPa = 71%).

Abstract

Porous concrete is used in infrastructure projects that require water absorption, supporting green cities and sustainable development. Its composition differs from conventional concrete because it has minimal or no fine aggregates, thus forming pores. This study aims to compare the compressive strength of normal porous concrete with porous concrete in which some of the cement is replaced with gypsum board waste powder. Testing was conducted at 7, 14, and 28 days to determine the effect of waste on concrete strength development. Compressive strength testing of porous concrete with varying amounts of gypsum powder waste showed that at 0% composition, the results at 7 and 14 days met the SNI 1974: 2011 standard. However, at 5% and 10% composition, the results at 7 days only partially met the standard, while at 14 days they were below the minimum limit of 88%. This indicates a decrease in compressive strength performance as the percentage of gypsum waste increases.

Abstract

Arsitektur merupakan perwujudan hasil penerapan ilmu pengetahuan, teknologi dan seni secara utuh dalam bentuk ruang dan lingkungan binaan sebagai bagian dari budaya dan peradaban manusia, pemenuhan fungsi, prinsip bangunan dan prinsip estetika serta memasukkan faktor keselamatan, kesehatan, kenyamanan dan kemudahan. Sebagai arsitek profesional yang merancang rencana arsitektur dan sebagai penulis, pencipta suatu karya memiliki hak atas karyanya. Untuk mendefinisikannya, pemilik hak cipta adalah pencipta sendiri sebagai pemilik hak cipta atau orang yang menerima hak pencipta, dan dapat disimpulkan bahwa pencipta karya desain secara otomatis adalah pemilik hak cipta setelah penciptaan dengan prinsip deklaratif. Faktanya adalah pelanggaran gambar online semakin meluas, namun pelaku pelanggaran gambar online selalu terbebas dari tuntutan hukum karena tidak ada aturan khusus tentang pelanggaran gambar online seperti di Indonesia.
