Abstract

Interstellar exploration faces fundamental challenges due to the time dilation effects of Einstein's theory of relativity. This review presents a comprehensive analysis of the principle of time dilation, implications for interstellar missions, as well as cutting-edge technologies that utilize this principle. The Systematic Literature Review (SLR) method with PRISMA approach was applied, resulting in 42 relevant articles that met the inclusion criteria. The review results show that: (1) the effects of time dilation pose significant challenges in interstellar mission planning, particularly in the aspects of navigation, communication, and crew biology; (2) the development of cutting-edge technologies such as the Breakthrough Starshot relativistic vehicle, high-precision atomic clocks, and autonomous AI systems offer innovative solutions to overcome these challenges; (3) the integration of relativity understanding with these advanced technologies opens up new opportunities to realize interstellar exploration in the coming decades. These findings confirm that although time dilation is a major obstacle, the development of revolutionary technologies can turn it into a supporting factor in the realization of interstellar missions.

Abstract

The transportation sector on land in Indonesia is responsible for about 27% of the country's total greenhouse gas emissions, which has a big effect on global warming (KLHK, 2021; WRI Indonesia, 2024). This study looks at trends in vehicle emissions, the main ways emissions are measured, and where more research is needed. It uses a Systematic Literature Review (SLR) method based on the PRISMA 2020 guidelines. The research searched five major databases: Scopus, ScienceDirect, Google Scholar, Portal Garuda, and Sinta, covering the time from January 1, 2015, to December 31, 2025. Out of 512 records found, 26 articles were included after going through a careful selection process. The results show that the number of cars owned increased by about 7–8% each year from 2015 to 2019, and this rate went up to 10–12% every year between 2021 and 2025 after the pandemic. By April 2025, the total number of vehicles in the country was around 168 million, with motorcycles making up most of that number, between 139 and 157 million. Most studies used the bottom-up method (69% of them), and most empirical research was done in Jakarta (14 articles), Surabaya (8 articles), and Bandung (4 articles). Medium-sized cities like Palembang, Medan, and Makassar have not been studied much and are considered scientific blind spots. In 2025, the transportation sector is expected to account for about 24.63% of the country's greenhouse gas emissions in 2024 and might rise to 28% of total carbon emissions from transport. During the dry season, urban areas have air pollution levels that are 42–57% from motor vehicles. More research in these cities is needed to help Indonesia reach its 2030 Nationally Determined Contribution (NDC) goals. This includes making better emission inventories and looking at possible ways to reduce emissions, such as switching to low-emission vehicles, which could help avoid up to 170 million tons of carbon emissions by 2040.
