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

Roads are transportation infrastructure whose needs in Indonesia continue to increase, along with the increasing number of vehicles. Road construction is a construction that receives traffic loads, therefore it is expected that a road pavement layer must have a strong pavement construction and be able to receive loads from traffic users. AC-WC (Black-top Concrete - Wearing Course) asphalt layer is a road pavement construction consisting of asphalt composition, coarse aggregate, fine aggregate and filler. Fillers in asphalt mixtures function to increase the binding power of AC-WC asphalt, so as to improve mixture stability and fillers can fill the voids between aggregate particles, filler commonly used is stone ash. This research will be conducted with the addition of broiler eggshell filler and porland cement in the Asphalt Concrete wearing Course (AC-WC) mixture. The research was conducted with an experimental method conducted in the Civil Engineering laboratory of Abdurrab University. The specification used in this study is Public Road Revision 2 Year 2018, The optimum asphalt content (KAO) used was 6.5%. Based on the results of the study, the largest marshall stability and melting value is found in the 100% cement filler variation, which is 1772.7 Kg and the value of flow value (melting) 3.77 mm while the largest marshall quotient (MQ) value is found in the 25% eggshell filler variation, 75% cement, which is 529.2 Kg/mm.

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.
