Abstract

Limbah hasil galian Aspal Hot Mix (AHM) umumnya tidak dimanfaatkan kembali dan hanya menjadi tumpukan material bongkaran yang terbengkalai di lingkungan sekitar proyek. Material ini sering dianggap memiliki kualitas rendah dan tidak layak digunakan kembali sebagai bahan konstruksi. Penelitian ini bertujuan untuk mengevaluasi potensi pemanfaatan limbah galian AHM sebagai bahan campuran dalam pembuatan Lapis Pondasi Atas (LPA) pada konstruksi perkerasan jalan. Pengujian dilakukan dengan metode laboratorium menggunakan lima variasi campuran limbah galian AHM, yaitu 0%, 10%, 20%, 30%, 40%, dan 50%, menggantikan batu pecah ukuran 1–2 cm. Evaluasi kinerja dilakukan berdasarkan nilai rendaman California Bearing Ratio (CBR). Hasil pengujian menunjukkan bahwa campuran dengan 20% limbah galian AHM menghasilkan nilai CBR rendaman sebesar 100,2%, sedangkan campuran 30% menghasilkan nilai CBR rendaman sebesar 94,4%. Kedua nilai tersebut melebihi batas minimum yang disyaratkan dalam Spesifikasi Umum Bina Marga 2018 Revisi 2, yaitu sebesar 90%. Dengan demikian, limbah galian AHM memiliki potensi yang baik sebagai material alternatif untuk LPA, yang tidak hanya mendukung efisiensi biaya, tetapi juga berkontribusi terhadap pengurangan limbah konstruksi.   Excavated Hot Mix Asphalt (HMA) waste is generally not reused and often accumulates as discarded demolition material in the vicinity of project sites. This material is frequently considered to be of low quality and unsuitable for reuse as construction material. This research aims to evaluate the potential of utilizing excavated HMA waste as a mixed material in the production of Base Course (LPA) for road pavement construction.The study was conducted using laboratory methods with five variations of excavated HMA waste mixtures: 0%, 10%, 20%, 30%, 40%, and 50%, replacing 1-2 cm crushed stone. Performance evaluation was based on the soaked California Bearing Ratio (CBR) values.The test results showed that the mixture with 20% excavated HMA waste yielded a soaked CBR value of 100.2%, while the 30% mixture resulted in a soaked CBR value of 94.4%. Both of these values exceed the minimum requirement of 90% stipulated in the Bina Marga General Specification 2018 Revision 2.Therefore, excavated HMA waste has good potential as an alternative material for Base Course (LPA), which not only supports cost efficiency but also contributes to the reduction of construction waste.

Abstract

This study assesses the financial feasibility of a privately financed infrastructure project under a Build-Operate-Transfer (BOT) scheme with a total investment of USD 76 million. The investment is distributed over a three-year construction phase, followed by a 30- to 60-year operation period generating annual net profits of USD 8.64 million. Key financial metrics including Net Present Value (NPV) and Internal Rate of Return (IRR) are utilized to evaluate the project. The results indicate a negative NPV of approximately USD -14.85 million for a 30-year operation, suggesting the project is not viable under a conservative time horizon. However, extending the operation to 60 years yields a positive NPV of USD +23.8 million and an estimated IRR of 11.7%, surpassing the assumed discount rate of 10%. These findings highlight the importance of operational duration in BOT projects and suggest that long-term operation is essential to achieve financial sustainability. Recommendations include extending the concession period and optimizing cost structures to enhance investment attractiveness.

Abstract

The toll road of Padang - Sicincin uses earth embankments in the construction process. In earth filling work, there is a target that must be met, namely that it must be able to spread and compact the soil by 1,474,809 m3/day, where this volume is the plan to meet the target that has been set. The problem that is currently occurring is that the land for the toll road entrance at STA 13+300 – 13+900 on Jalan Nagari Lubuk Alung has just been acquired in 2022. From the results of a field inspection that took approximately a week, there was a delay in terms of landfill work. in the field. Therefore, it is necessary to research to find out the causes of delays. The focus of this research is to determine the productivity of heavy equipment to determine solutions to catch up with work delays that are occurring. After conducting a review in the field, the results obtained from each heavy equipment were 1,471,150 m3/day (excavator), 1,464,610 m3/day (dump truck), 3,086,070 (bulldozer), and 4,150,272 m3/day. (vibro roller). From the results obtained, the excavators and dump trucks in the field were unable to meet the planned targets. Therefore, the handling efforts carried out are by increasing the number of excavators and dump trucks working in the field. Based on the results of calculations and analysis, to complete the embankment work on time, increase the number of tools by two units for excavators and three units for dump trucks. With this additional simulation, the time required to complete work in the field is 13 days faster than the planned time that had been made.

Abstract

Perencanaan Rencana Anggaran Biaya (RAB) merupakan tahapan penting dalam proyek konstruksi untuk menjamin ketepatan pengendalian biaya. Perbedaan metode analisis harga satuan dapat menghasilkan estimasi yang bervariasi dan memengaruhi pengambilan keputusan proyek. Penelitian ini bertujuan membandingkan estimasi biaya pekerjaan struktur menggunakan metode Analisa Harga Satuan Pekerjaan (AHSP) 2023, Standar Nasional Indonesia (SNI) 2008, dan Engineer Estimate. Metode penelitian yang digunakan adalah deskriptif kuantitatif dengan pendekatan studi kasus pada pembangunan Masjid Markaz Sunnah Nusantara Al-Hijrah di Kota Pekanbaru. Data yang digunakan berupa data sekunder meliputi AHSP 2023, SNI 2008, standar harga barang dan jasa Kota Pekanbaru tahun 2022, gambar kerja struktur, serta dokumen Engineer Estimate proyek. Hasil penelitian menunjukkan estimasi biaya metode AHSP 2023 sebesar Rp61.333.100.000, metode SNI 2008 sebesar Rp46.397.700.000, dan Engineer Estimate sebesar Rp47.292.800.000. Dibandingkan Engineer Estimate, metode AHSP 2023 menghasilkan estimasi lebih tinggi sekitar 29,69%, sedangkan SNI 2008 lebih rendah sekitar 1,89%, sehingga SNI 2008 merupakan metode yang paling mendekati Engineer Estimate pada studi kasus ini dan dapat menjadi acuan estimasi yang lebih ekonomis untuk pekerjaan struktur.   Cost Budget Planning (RAB) is a crucial stage in construction projects to ensure accurate cost control. Differences in unit price analysis methods may produce varying cost estimates and influence project decision-making. This study aims to compare structural work cost estimates using the 2023 Indonesian Unit Price Analysis Standard (AHSP 2023), the Indonesian National Standard (SNI 2008), and the Engineer Estimate method. A quantitative descriptive approach with a case study design was applied to the construction of the Markaz Sunnah Nusantara Al-Hijrah Mosque in Pekanbaru City. Secondary data were used, including AHSP 2023, SNI 2008, the 2022 standard prices for goods and services in Pekanbaru, structural drawings, and the project Engineer Estimate document. The results show that the estimated structural cost using AHSP 2023 is IDR 61,333,100,000, SNI 2008 is IDR 46,397,700,000, and the Engineer Estimate is IDR 47,292,800,000. Compared with the Engineer Estimate, AHSP 2023 produces an estimate about 29.69% higher, while SNI 2008 is about 1.89% lower. Therefore, SNI 2008 provides the closest estimate to the Engineer Estimate in this case study and may serve as a more economical reference for structural cost estimation.
