CO 2 emission has become a growing concern for most of the countries and many factors or reasons have been found to enhance this emission in one way or the other. In this particular study, the impact of biogas energy, wind energy and solar energy production is supposed to be studied on CO 2 emission in Indonesia. The author has collected data for research purpose from Indonesia. The data covers the period of 29 years and has been collected from authentic databases. After data collection process, several tests and techniques are used for the purpose of analyzing and exploring various aspects related to the study and the variables. The tests used by the author in this study include unit root test and GMM estimation technique. All these tests have distinct features and used for various purposes. The results obtained from the above-mentioned tests indicate that the production of all types of energies discussed in the study i.e. biogas, wind and solar energy have significant impacts on CO 2 emission while the impact of the only control variable, energy consumption is found to be insignificant. Various theoretical, practical and policy making implications have been identified by the author and some limitations of the study have also been discussed in the last.
In traditional context, fossil fuel energy consumption is observed as non-renewable sources and contributing its major part for the energy source in the world economy. However, a new term under the title of renewable energy source is also examined and studied too. The focus of this paper is to investigate the impact of fossil fuel energy and renewable energy sources on the factor of climate change. For the measurement of climate change, overall six dimensions were added in the empirical analyses. The time period for the study was 1987 to 2013 and data was collected from World Development Indicator WDI. Findings for the regression analyses reveal that climate change in terms of CO 2 emissions from liquid fuel consumption (kt) or C 1 is directly influenced by both fossil and renewable energy, and same trend is found for CO 2 emissions (kt); C 2 . Meanwhile, the third indicator of climate change C 3 or CO 2 emissions (kg per 2010 US$ of GDP) is negatively affected by renewable energy. Furthermore, C 4 (CO 2 emissions from gaseous fuel consumption [% of total]) is directly influenced by both of the energy sources in Thailand. Additionally, the trends in C 5 is found to be positively determined by both fossil fuel and renewable energy, while their negative and significant impact is observed for C 6 ; CO 2 emissions from transport (% of total fuel combustion). Future research studies may consider the sub division of energy sources in both public and private sectors.
Increased economic growth and transportation have led to a great increase in carbon emission in Malaysia. This paper investigates the factors such as distance travel (DT), fuel efficiency (FE), fuel price (FP) and fuel consumption as determinants of carbon emission from road transportation in Malaysia for the period 1990 to 2019. The results indicate that DT, FP, and FE are the main determinants of carbon emission. The study concludes that to reduce carbon emission in Malaysia, policies causing structural adjustments in the road transport sector of Malaysia must be implemented.
Abstrak Saat ini kualitas pelayanan menjadi permasalahan yang cukup sering terjadi untuk itu pemerintah berperan sebagai penyedia jasa untuk memenuhi keinginan maupun kebutuhan masyarakat. Kantor imigrasi 1 kota Bandung adalah salah satu lembaga pemerintah yang bergerak dalam bidang pelayanan yang berkaitan dengan keimigrasian dan salah satu pelayanan yang menjadi sorotan yaitu pembuatan paspor karena dalam proses pembuatannya masih belum optimal. Tujuan penelitian untuk mengetahui masalah pelayanan di kantor imigrasi kota Bandung. Penelitian ini menggunakan metode kualitatif dengan pendekatan deskriptif. Berdasarkan penelitian, ditemukan hasil bahwa kelima dimensi tersebut sudah berjalan dengan baik, hanya saja perlu adanya peningkatan peningkatan pada setiap dimensinya seperti pada dimensi tangibles yang diharapkan untuk meningkatkan kualitas aplikasi onlinenya, dimensi responsiveness yang diharapkan dapat mengembangkan sistemnya serta dimensi emphathy yang diharapkan agar lebih ditingkatkan lagi kualitas SDMnya. Abstract Currently, the quality of service is a problem that occurs quite often, for the government acts as a service provider to meet the wishes and needs of the community. Immigration office 1 Bandung is one of the government agencies engaged in services related to immigration and one of the services that are in the spotlight is making passports because the manufacturing process is still not optimal. The purpose of this research is to find out service problems at the immigration office in the city of Bandung. This study uses a qualitative method with a descriptive approach. Based on the research, it was found that the five dimensions have been running well, it's just that there needs to be an increase in each dimension such as the tangibles dimension which is expected to improve the quality of the online application, the responsiveness dimension which is expected to develop the system and the empathy dimension which is expected to be further improved. the quality of human resources.
