The purpose of this study is to create projections of the population in West Java Province in the period of 2025-2035. The method used in this research is a mixed method which is a combination of the Mathematical Method and the Component Method. The Mathematical Method is used to make projections of the total population, while the Component Method is used to make projections of the total population and population per age group. Using basic population data from the 2020 Population Census, the projection of the population of West Java in 2025, 2030, and 2035 is 51,117,160 people, 54,127,589 people, and 57,315,311 people, respectively.Tujuan penelitian ini adalah untuk membuat proyeksi penduduk Jawa Barat tahun 2025-2035. Metode yang digunakan dalam penelitian ini adalah metode campuran yang merupakan gabungan Metode Matematik dan Metode Komponen. Metode Matematik digunakan untuk membuat proyeksi total penduduk, sedangkan Metode Komponen digunakan untuk membuat proyeksi total penduduk dan penduduk per kelompok umur. Dengan menggunakan data dasar jumlah penduduk hasil sensus penduduk 2020, diperoleh proyeksi penduduk Jawa Barat tahun 2025, tahun 2030, dan tahun 2035, berturut-turut adalah 51.117.160 orang, 54.127.589 orang, dan 57.315.311 orang.

This study aims to analyze the development of scientometric research from the theme of urban economic development. The analysis was carried out on 360 articles indexed by Dimension.ai. The method used is scientometric using R Bibliometrix Biblioshiny and VosViewer as processing tools. The results obtained are that this theme has begun to develop significantly in 2020 until now. Research in urban economic development is dominantly published by Chinese authors and affiliates in reputable journals. Research opportunities from urban economic development in emerging themes found the topics of city, innovation, metropolitan, planning, future, and change. This indicates that the potential research themes are in the city planning area which is “innovative”, “future-oriented” and able to “adapt the technology” in “the face of change”. Potential topics in urban economic development were found to have changed from 1964-2013 to 2014-2020 which focused on urban, data, local, contemporary, design and cities. These results can be used as input in compiling research on the theme of urban economic development research and to help researchers find novelty and sustainable impact contributions.

Environmental degradation is one of the many environmental problems that need to be faced by every country in the world. Both developed and developing countries can find environmental degradation problems in various conditions and phenomena. One of the environmental problems in Southeast Asia is related to smog. Indonesia is one of the countries with high cases of smog pollution, this is because the vast forest area with massive land clearing makes forest fires frequent. respond. The ASEAN Agreement on Transboundary Haze Pollution is an agreement to control haze pollution that occurs in the Southeast Asian region. This study uses secondary data originating from the Indonesia Central Statistics Agency (BPS) with a quantitative method approach. This study seeks to find the phenomenon of environmental pollution, economy, and emission developments in Indonesia. It was found that energy emissions, FOLU, and forest fires were the three emissions that were not affected by the ASEAN Agreement on Transboundary Haze Pollution policy. The policy that Indonesia needs to take is to improve energy emission, fire disaster and FOLU control.
