Abstract

Transportation infrastructure development is one of the vital aspects needed to improve the economic growth of a country. In Indonesia, transportation infrastructure development in the next 15 years requires an estimated investment of IDR 1,785 trilion. This figure includes IDR 339 trilion investment for roads, IDR117 trilion for ports, IDR 32 trilion for airports, and IDR 326 trilion for railways. Public Private Partnership (PPP) approach is used in the infrastructure development program as an alternative to finance transportation infrastructure projects in Indonesia. This paper aims to discuss the historical development of PPP policy inIndonesia in an effort to create Value for Money in the infrastructure development projects. Furthermore, various studies on the key success factors of successful implementation of PPP schemes in other countries and the strategic action from Indonesian government to produce a range of policies that support the implementation of the PPP scheme since 1998-2012 are also discussed.Keywords: Public Private Partnership, transportation infrastructure, project financing.

Abstract

ABSTRAK Tren pertumbuhan nilai aset properti milik negara terus bertambah. Sebagian aset tersebut berpotensi untuk diinvestasikan terutama aset properti yang berstatus idle. Salah satu portofolio yang dapat dimanfaatkan adalah properti komersil. Agar aset idle dapat dimanfaatkan, harus dilakukan analisa peruntukan lahan terlebih dahulu. Dalam analisa peruntukan lahan, hal yang membedakan antara penelitian ini dengan penelitian sebelumnya adalah penggunaan kriteria untuk penilaian aspek lokasi. Dalam penelitian ini, kriteria yang digunakan memiliki persyaratan yang spesifik bagi setiap properti. Sedangkan kriteria yang digunakan dalam penelitian sebelumnya tidak dikhususkan serta dibedakan sesuai jenis propertinya. Tujuan penelitian ini adalah menyusun model untuk melakukan pemilihan jenis properti yang sesuai pada aset negara berdasarkan aspek lokasi. Model dikembangkan menggunakan pendekatan multikriteria. Bobot kriteria ditentukan menggunakan metode Analitycal Hierarchy Process (AHP). Sedangkan penentuan parameter kriteria lokasi sebagai persyaratan kriteria lokasi dilakukan menggunakan metode Fuzzy Sets. Adapun metode skoring digunakan untuk menentukan properti prioritas. Pengujian model dilakukan terhadap 5 (lima) aset negara yang terletak di DKI Jakarta. Hasil pengujian menunjukkan bahwa model mampu melakukan pemilihan bisnis properti yang sesuai pada aset negara. Properti yang terpilih juga tidak melanggar zonasi peruntukan kawasan. Pengujian model juga menunjukkan bagaimana pemilihan bisnis properti diselesaikan secara sederhana dan mudah. Sehingga diharapkan model dapat membantu para pihak yang terlibat dalam tahapan awal pengembangan properti untuk memilih bisnis properti yang layak.

Abstract

Management area of leadership and commitment in the quality management system is a mean to achieve successful functions, even more on construction industry. The objective of this research is to analyze the correlation between leadership and commitment focus management area and quality performance as indicated by rework. Research location is uranium (U), thorium (Th), and rare earth elements (REE) processing pilot plant construction area in Center for Nuclear Minerals Technology-BATAN. Primary data were collected from the 36 of 37 submitted questionnaires, and representing 97 % response rate. The research used descriptive analysis, which depends on the poll and the use of Statistical Package for the Social Sciences (SPSS) main program for data analysis. The relationship between leadership and commitment and quality performance was analyzed using spearman rank correlation coefficient. Findings of research provide guideline and alert to project managers or management of organization where leadership, commitment, infrastructure, and environmental work have moderate to strong correlation to rework level. The results further revealed that there is no relationship between responsibility and authority for the management system and organizational policy and construction quality performance. The research provides evidence, in fact to achieve the quality performance of a pilot plant construction must be concerned with leadership attribute, maintaining commitment and provide support resources on the whole project cycle.  Area manajemen kepemimpinan dan komitmen dalam sistem manajemen mutu adalah sarana untuk mencapai keberhasilan suatu pekerjaan, terlebih pada industri konstruksi.

Abstract

Green Building (GB) is a design concept that implements sustainable processes and green technologies in the building’s life cycle. However, the design process of GB tends to take longer than conventional buildings due to the integration of various green requirements and performances into the building design. Technological advances are continually improving the quality of human life by providing solutions to problems they encounter, such as the machine learning (ML) technique utilized to develop predictive and classification models. This study aims to develop a GB design prediction by employing an ML approach by considering four GB design criteria: energy efficiency, indoor environmental quality, water efficiency, and site planning. A dataset of GB projects collected from a private construction company based in Jakarta was used to train and test the ML model. Mean Square Error (MSE) was used to evaluate the model accuracy. The comparison of MSE results of the conducted experiments showed that the combination of the ANN method with the IF-ELSE algorithm resulted in the most accurate ML model for GB design prediction with an MSE of 1.3, creating a predictive model that improves the time efficiency of GB design process.

Abstract

Reliability of a road is mandatory since damaged will impede the traffic. Destruction is caused by various factors; one of the most important factors is excess load. Overload may give the load of each axle of a vehicle exceeds the determined standard. This condition occurs in trucks exceeding the load limit. In designing the structure of a road based on the method of Directorate General of Highways Ministry of Public Works of the Republic of Indonesia, axle load calculated in equivalent-number, or known as equivalent axle load (EAL), of 8.16 tons of standard axle. Total equivalent-number over the service life is defined as cumulative equivalent standard axle load (CESA). Due to traffic volume exceeding the volume forecast or, in other words there is an excessive load of traffic, it will make CESA achieved faster than planned. This excessive load in Indonesia, however, has been considered as a factor of environmental condition, so there is a need to introduce a correction factor for EAL as high as 20-25% in the process of designing flexible and rigid pavement so as to reduce early damage.

Abstract

Soekarno–Hatta Airport is the main gateway for international flights to Greater Jakarta. Its accessibility depends on the inter-city and Sedyatmo toll roads, which causes congestion in peak hours, leading to uncertainty about travel times. The Soekarno–Hatta International Airport Rail Link (SHIARL) is proposed as an alternative mass transportation project, which is expected to provide accessibility and mobility for people and goods to and from the airport. Previously, the project was unattractive to private investors as it was technically and financially unfeasible. Therefore, this research aims to improve the feasibility of the Soekarno-Hatta International Airport Rail Link (SHIARL) by using a value-engineering approach to create maximum value for money for the project. This research combines quantitative and qualitative methods. Questionnaire surveys are distributed to various stakeholders in the project, and a focus-group discussion (FGD) is conducted. The results identified additional, innovative functions through the integration of the Mass Rapid Transit (MRT), flood control, telecommunications, and development in the downtown area around the station. The life-cycle cost analysis confirmed the increased value for money because of the project’s additional functions, including a positive Net Present Value (NPV). Moreover, the findings showed that the internal rate of return (IRR) was 3% higher than the original single-function project.

Abstract

Indonesian government attempts to improve connectivity and to increase regional activities in Sumatera Island through the development of Trans Sumatera Toll Road (TSTR). However, despite its benefits to local economic development in Sumatera, the project shows low feasibility due to a low amount of investment. It can be attributed from the lack of planning in the initial phase to produce a comprehensive route that considers the various potentials of the regions. Thus, this research aims to investigate alternative route planning of Trans Sumatera Toll Road particularly in this paper for Central Sumatera by studying Gross Regional Domestic Product (GRDP), population and other significant factors. This research exposes cities and districts in Riau, West Sumatera, and Jambi which potentially contribute to the regional economy. Each selected towns and districts will be integrated with the intermodal system and connected to other functions to establish the Trans Sumatera Toll Road project in Central Sumatera. Compared to existing estimation of investment from public records, this alternative route has generated a competitive cost of investment which is estimated around 118,053,400,074,696 rupiahs. The research findings are expected to become the basis to improve other similar infrastructure toll road project development.
