Urbanization in Indonesia has led to increased waste generation, posing significant challenges to sustainability. Until now, the method for collecting and transporting waste in Indonesia is still done manually. Nusantara, the New State Capital of Indonesia, aims to address these challenges through the adoption of a Smart Waste Management System (SWMS), leveraging IoT and ICT technologies. This paper reviews the current state of technology research in this field. The proposed SWMS framework integrates various types of sensors for waste monitoring, categorizing, and real-time tracking. This system enhances operational efficiency by triggering waste pickup when bin fill levels exceed a set threshold and directing waste pickup vehicles equipped with GPS and surveillance systems to specific locations. Managed by a central management system accessible via web or mobile applications, this framework exemplifies an innovative approach to waste management in Nusantara, aligning with the city’s vision of becoming a smart and sustainable urban area. The paper concludes that integrating IoT and ICT in waste management is crucial for achieving sustainable urban environments. The successful implementation of SWMS in Nusantara could serve as a model for other cities globally.

The rise of large cities worldwide has spurred the emergence of Transit Oriented Development (TOD) as an urban planning concept. Indonesia, including Jakarta, has begun implementing TOD strategies. To facilitate TOD in Indonesia, this study proposes a conceptual mobile app, TOD.id, informed by preliminary research. It introduces a novel tax approach, Land Value Capture (LVC) tax, to address funding challenges, which account for up to 53.8% of the problem. However, TOD.id remains in a developmental phase, with all features in the conceptual stage, making it unsuitable for immediate market launch. During this stage, this research aims to enhance the TOD.id mobile app by refining existing features and exploring potential new functionalities, which will be based by literature review and benchmarking against similar existing apps in Indonesia. The study employs a desk study method, a qualitative benchmark study method, and the collection of qualitative data. The outcomes of this research are expected to pave the way for the optimal realization of TOD.id in the Indonesian market, aligning with the projections from previous studies.

As stated in the Nationally Determined Contribution (NDC) document, which establishes emission reduction objectives for 2030, the Government of Indonesia has ratified the Paris Agreement, a worldwide agreement to decrease emissions of greenhouse gases (GHG) and to address the consequences of climate change. This was accomplished through Law No. 16 of 2016. To achieve zero emissions, Indonesia focuses on reducing the use of fossil fuels, adopting environmentally friendly technologies, and increasing the utilization of renewable energy. Global environmental challenges, driven by climate change, have far-reaching implications, including severe health and economic consequences. This study aims to explores the strategies globally performed to reduce the carbon emissions of buildings. To obtain that objective, this study uses a qualitative literature review. The study shows that strategies that can help reduce the buildings carbon emissions include population dynamics, solar photovoltaic, solar water heaters, material use, energy consumption, building stock, and economic considerations. The finding presents a unique opportunity for prioritizing green building practices and carbon emission reduction strategies in Indonesia.

Public-Private Partnership (PPP) schemes in delivering economic and social infrastructure are growing in developing countries worldwide. Various developing countries, including Indonesia, has also been preparing and developing numerous projects, ranging from larger-scale economic infrastructures that include toll roads to multifunction satellites and smaller-scale social infrastructures that include water supply, solid-waste management, and regional hospital projects. With the increasing numbers of smaller infrastructure projects proposed by the local government, attracting financers to invest in these projects is still a challenge the government faces. Financial institutions are still averse to making the appraisal and due diligence to such projects, owing to the nature of little historical evidence of private finance involvement in small-scale infrastructure finance. In some western countries, citizens have taken the initiative to forward and finance their local infrastructure development due to realizing the social, economic, and environmental benefits of civic projects for the local community. Theoretical research has shown the opportunity of utilizing crowdfunding for local urban infrastructure; however, the factors contributing to benefit from this finance method are yet to be identified. This paper seeks to answer questions on what success factors contribute to the opportunity to adapt the crowdfunding scheme to finance a smaller-scale urban infrastructure project by conducting qualitative literature review.

Construction is a crucial industry that drives a nation's economic growth, yet it often faces inherent challenges related to productivity and waste generation. Lean Construction (LC) has emerged as a promising approach to address these challenges. However, despite its success in various construction projects, some gaps in the practical adoption of LC hinder its widespread practitioner uptake. Therefore, to close the gap, the objective of this study is threefold: identify waste factors of construction activities, determine suitable lean tools for project performance improvement, and assess the impacts of the implementation of lean tools on project completion time and costs. A toll road project in Indonesia was investigated as the case study. A combined research method was employed by administering a questionnaire survey to pertinent project participants, conducting in-depth interviews, and analyzing relevant documents to achieve these objectives. This study discovered 15 non-value-added (NVA) activities that can be eliminated to enhance overall project performance. Most of these activities can be accommodated using coordination and collaboration, while some require a more comprehensive approach, including standardization, the Five S, crash programs, and overlapping techniques. Implementing lean tools resulted in a 19.17% reduction in project completion time, although it contributed to a 5.33% decrease in organizational profit compared to traditional approaches. The findings of this study hold the potential to benefit those facing similar issues, not only in emerging countries but also in developed economies grappling with similar contexts.
