Abstract

ABSTRAK Pembangunan Gedung Perkuliahan sebagai bagian dari Proyek Infrastruktur sering menghadapi tantangan Efisiensi Biaya dan Waktu. Penelitian ini bertujuan untuk menganalisis penerapan Value Engineering (VE) sebagai pendekatan sistematis dalam mengurangi biaya proyek Pembangunan Gedung Kuliah 12 lantai dengan luas total 24.000 m² dan nilai anggaran sebesar Rp.164.668.171.695,00. Fokus penelitian ini adalah pada pekerjaan struktur, khususnya elemen Plat Lantai yang dinilai memiliki potensi penghematan tertinggi tanpa mengganggu sistem struktur utama bangunan. Metode penelitian meliputi analisis dokumen proyek, wawancara, serta kajian terhadap alternatif desain berbasis VE. Hasil penelitian menunjukkan bahwa penggunaan Hollow Core Slab (HCS) sebagai pengganti Plat Beton Bertulang Konvensional dapat mengurangi biaya sebesar Rp3.492.288.479,00 atau 18,14% dari desain awal, serta mempercepat waktu pelaksanaan hingga 53 hari atau 21,03%. Penelitian ini merekomendasikan penerapan VE secara sistematis pada proyek konstruksi serupa untuk mengoptimalkan sumber daya dan meningkatkan efisiensi proyek. Penelitian ini memberikan kontribusi keilmuan pada wawasan praktis dan teoretis mengenai penerapan VE dalam konteks proyek pendidikan tinggi di Indonesia, termasuk implikasi terhadap regulasi dan praktik konstruksi lokal. Mengevaluasi efisiensi penggunaan Hollow Core Slab (HCS) sebagai alternatif elemen plat lantai dalam proyek gedung pendidikan tinggi bertingkat tinggi di Indonesia.  Temuan ini selaras dengan prinsip tata ruang yang mengedepankan optimalisasi penggunaan lahan dan efisiensi ruang vertikal, khususnya di kawasan perkotaan padat, sehingga dapat menjadi referensi dalam penyusunan kebijakan zonasi pendidikan berbasis konstruksi berkelanjutanKata Kunci: Value Engineering, Efisiensi Biaya, Efisiensi Waktu, Proyek Konstruksi, Hollow Core Slab ABSTRACTThe construction of university buildings, as part of infrastructure development projects, often encounters challenges related to cost and time efficiency. This study aims to analyze the application of Value Engineering (VE) as a systematic approach to reduce the overall budget of a 12-story university building project with a total floor area of 24,000 m² and a budget of IDR 164,668,171,695. The research focuses on the structural works, particularly the floor slab component, which is considered to have the highest potential for savings without compromising the integrity of the main structural system. The methodology involves project document analysis, interviews, and evaluation of VE-based alternative designs. The findings reveal that substituting the conventional reinforced concrete slab with a Hollow Core Slab (HCS) can reduce costs by IDR 3,492,288,479 or 18,14% of the original design and shorten the construction duration by up to 53 days or 21.03%. This study recommends the systematic application of VE in similar construction projects to optimize resource utilization and improve project efficiency. The research offers both practical and theoretical contributions to the discourse on VE implementation in higher education building projects in Indonesia, including implications for national construction regulations and practices. It also evaluates the efficiency of HCS as an alternative floor slab system in high-rise educational facilities. These findings align with spatial planning principles that emphasize optimal land use and vertical space efficiency, especially in dense urban areas, and may serve as a reference for developing sustainable, construction-based zoning policies for educational areas.Keywords: Value Engineering, Cost Efficiency, Time Efficiency, Construction Project, Hollow Core Slab

Abstract

The use of rigid pavement waste as recycled aggregate in concrete has become a focus of research in an effort to improve sustainability in the construction industry. This article discusses the main challenges in using rigid pavement waste as recycled aggregate, especially related to the mechanical strength of concrete, such as compressive and flexural strength. In addition, this article also explores various innovations in concrete mix design that can overcome the mechanical performance weaknesses of recycled concrete. Some of the solutions discussed include the use of reinforcing fibers, alternative binders, and more efficient production technologies. The research shows that these innovations can significantly improve the performance of recycled concrete with rigid pavement waste aggregate, making it a viable option to support more environmentally friendly infrastructure development.

Abstract

Inaccuracy in planning project activities during project implementation greatly affects implementation delays in the field. The purpose of the study is to determine and analyze: (1) the causal factors that contribute to project completion delays, (2) the causal factors that contribute to the dominant delay in project completion, and (3) delay risk management. In the Sports facilities (Eastern Tribune Development) project. Cirebon Regency. This study is a type of quantitative descriptive study. Data collection was done through FGD, interviews and questionnaires distributed to 10 qualified respondents in the construction sector. The resources of this study are the cause of the delay in the completion of the projects. A House of Risk (HOR) approach was used to analyze the data. Research results show that (1) Cirebon Regency Sports Facilities Building (Eastern Tribune Development) project has 14 risk events and 17 identified risk causes that cause delays. (2) Control factors that cause delays in project completion include: material factors, contract document factors, project owner factors, and contractor and design consultant factors, and (3) delay risk management options, including: (a) good communication and coordination. with the owner; (b) apply a comprehensive planning approach to procurement of materials, (c) coordinate current project drawings between consultants and field workers, (d) contact consultants and supervisors.
