Abstract

The increasing demand for coal energy globally has led to the rapid growth of the coal industry in Indonesia. It is projected that coal energy will still dominate in the world until 2050. This development will undoubtedly impact the quality of the environment, one of which is related to air pollution. As one of the distribution chain links, coal port facilities require attention regarding air quality management. This research shows that the source of fugitive pollutants from coal loading and unloading activities at the research location comes from supporting equipment for loading and unloading activities and coal stockpiles. These tools continuously emit non-chimney contaminants, namely coal dust. Non-fugitive pollution is generated by heavy equipment and generators used in activities in the workshop area. Measurement of ambient air quality at the study site indicated that the particulate parameters (TSP, PM10, and Dustfall) needed to be comparable with the standards. In contrast, the gas parameter that was the most significant was the SO2 pollutant. Efforts to control air pollution are using sprinklers and installing windproof nets, which are indicated to be quite effective in reducing dust in the crusher area. Recommendations in controlling air pollution are to automate the sprinkler system for watering and monitoring airflow and plant trees with the ability to absorb SO2 effectively.

Abstract

 ABSTRAKPartikulat merupakan salah satu polutan utama yang dihasilkan baik dari industri ataupun transportasi. Partikulat merupakan salah satu polutan kualitas udara yang paling merusak kesehatan dan juga diketahui sebagai karsinogenik. Emission trading ataupun emission offset merupakan salah satu tools yang efektif untuk menurunkan emisi. Konsepnya berlawanan dengan pendekatan tradisional yaitu dengan ’command and control’ namun menggantungkan usaha reduksi emisi kepada mekanisme pasar untuk mendapatkan cara yang paling murah dan efektif. Program atau inisiatif Emission Offset akan lebih tepat manfaatnya jika dilakukan pada lokasi yang spesisifik. penurunan emisi. Dalam trade hal yang diperhitungkan adalah supply (ketersediaan), demand (kebutuhan), sehingga dapat memperkirakan market clearing prices atau harga (emission reduction credit) ERC yang tepat. Institusi kelembagaan di Indonesia yang dapat memiliki kewenangan untuk berkoordinasi melakukan emission offset sudah tersedia. beberapa regulasi yang perlu ada antara lain terkait wilayah pengelolaan kualitas udara (WPKU) dan kebijakan pendukung lain. Secara teknis kebutuhan data terkait pengukuran emisi sangat diperlukan, data wajib transparan dan dapat dipertanggung jawabkan. Selain itu, diperlukan juga validasi dari laboratorium yang telah ditunjuk. Tujuan penelitian ini untuk dapat mengidentifikasi konsentrasi partikulat, menentukan skala sistem emission offset baik itu luas kawasan, sumber pencemar yang dituju, ataupun parameter kritis yang akan dikendalikan. Maka metode penelitian yang digunakan antara lain pemantauan kualitas udara yang tersebar di seluruh wilayah Indonesia pada lokasi yang spesisifik., dan juga inventarisasi emisi dimana penentuan emission cap polutan partikulat (PM2.5 dan PM10) berbagai system offset emission caps ditentukan melalui proses politik yang menyeimbangkan antara cost and benefits dari penurunan emisi. Kata Kunci : Emission Offset, Emmision Trading, ERC, Indonesia, Partikulat ABSTRACT Potential Overview Of Particulate Concentration Control With Offset Emission Program In Indonesia. Particulate is one of the main pollutants produced either from industry or transportation. Particulates are one of the most damaging air quality pollutants to health and are also known to be carcinogenic. emission trading or emission offset is one of the effective tools to reduce emissions. The concept is contrary to the traditional approach of 'command and control' but relies on emission reduction efforts to market mechanisms to find the cheapest and most effective way . Emission offset programs or initiatives will be more appropriate if they are carried out in specific locations. emission reduction. In trade, the things that are taken into account are supply (availability), demand (need), so that they can estimate the right market clearing prices or (Emission Reduction Credit) ERC prices. Institutional institutions in Indonesia that can have the authority to coordinate Emission Offset are already available. Several regulations that need to exist include those related to the air quality management area (WPKU) and other supporting policies. Technically, the need for data related to emission measurement is very necessary, the data must be transparent and can be accounted for. In addition, validation from a designated laboratory is also required. The purpose of this study is to identify particulate concentrations, determine the scale of the emission offset system, whether it is the area, the source of the pollutant being targeted, or the critical parameters to be controlled. So the research methods used include monitoring air quality spread throughout Indonesia in specific locations, and also an emission inventory where the determination of the emission cap of particulate pollutants (PM2.5 and PM10) of various offset emission caps systems is determined through a balanced political process. between the costs and benefits of reducing emissions. Keywords : emission offset, emmision trading, ERC, Indonesia, particulate

Abstract

Radin Inten II International Airport is the largest airport in Lampung Province which in 2019 underwent a status change to become an international airport. This article tries to present changes in the acoustic environment caused by flight activities around the airport. Noise measurements were carried out at 12 sampling points in the range of 300-4000 m and under the flight path, which then calculated the noise level (Leq) and the WECPNL index. Contour mapping of noise exposure uses an overlay technique visualized with contour lines. Leq measurement results are 60.4-81.4 dBA with an average value of 69.8 dBA. The distance of the sampling point to the runway is known to have a negative correlation with the noise level, while the noise measured on weekdays and weekends has no difference. The mapping results show that the most affected zones are dense settlements about 600 m from the runway. Three locations are known to fall into the noise level 3 zone, and two other sites fall into the noise level 1 and 2 zones. The non-noise zone is within a 2.5 km distance from the runway. The reduced comfort of living due to noise is a consequence of the economic improvement that may be felt by the people living around the airport.

Abstract

Data SIPSN tiga tahun terakhir menunjukkan timbulan sampah di Kabupaten Langkat meningkat 24,71% atau dari yang awalnya 152.099 menjadi 189.685 ton. Lebih dari 42% timbulan sampah disumbangkan oleh sektor domestik yang seharusnya dapat dikelola sedekat mungkin dari sumbernya. Dengan demikian, kegiatan pengabdian kepada masyarakat ini bertujuan memberikan pelatihan agar masyarakat lebih memahami cara mengurangi timbulan sampah dengan mengubahnya menjadi produk yang bermanfaat. Pelatihan dilaksanakan pada 5 Agustus 2021 di Rumah Komunitas Pohon Rindang, Desa Perkebunan Bukit Lawang, kepada 43 anak usia 8-15 tahun. Metode yang digunakan adalah penyuluhan interaktif dengan memberikan demonstrasi cara membuat keranjang takakura dan stringbag. Keranjang takakura 45x37x57 cm dapat menampung hingga 1,5 kg sampah organik basah per hari, sedangkan pembuatan pakaian bekas menjadi stringbag dapat menunda pembuangan material ke TPA. Dalam jangka panjang kegiatan ini diharapkan menjadi kebiasaan baru bagi masyarakat dalam mengelola sampah untuk menjadikan Desa Perkebunan Bukit Lawang sebagai desa pariwisata yang berkelanjutan.

Abstract

Urban water management efforts are essential in encouraging the fulfillment of the SDGs targets. One action that can be done is to approach the calculation of the actual water consumption value. This research conducted a survey of domestic water consumption in Bandar Lampung City to obtain comprehensive information. Bandar Lampung City was chosen because it is one of the cities on the island of Sumatra with a high economic growth rate. Lampung Province is the top 3 province in Sumatera Island with the higher Gross Domestic Product Growth on 2022, with Bandar Lampung as its capital city. Furthermore, water consumption patterns were analyzed for various activities, socio demographic conditions, and the community's economy. The results showed that of the 404 samples, the average water usage was 195.08 liters/person/day, with the dominant activities in use including bathing (66.84 liters/person/day), flushing the toilet (35.71 liters/person) / day), and ablution (29.74 liters/person/day). Furthermore, the variable number of family members in one house and income level have significant different on total domestic water consumption. The results obtained in this study are expected to assist in making decisions regarding urban water management plans.

Abstract

global warming and environmental issues are being caused by the overuse of fossil fuels and increased industrialization around the world, which has resulted in the production of greenhouse gases. As a result, it's crucial to reach net-zero carbon emissions. By balancing the total quantity of carbon dioxide or other greenhouse gas emissions over a specific period and taking actions that are ecologically responsible, net zero carbon emissions can be accomplished. For environmental sustainability to be successful, it must be able to influence people's attitudes and behavior toward the environment. To understand NGOs' obligations in supporting net-zero carbon emissions, this paper presents a methodical debate utilizing NGOs as case studies. The method is employed in this work by reviewing the body of primary and secondary research on the study issue. This essay initially lists different environmental NGOs organizations before categorizing and outlining some of the significant GHGs reduction initiatives made by these organizations. This essay also addresses key issues that must be addressed upon to achieve the best outcomes. This report gives a broad overview of the synergizing domains that NGOs around the globe work in to assist improvement environmental security.
