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

Abstrak: Ozon yang berada pada lapisan troposfer merupakan zat pencemar yang berbahaya bagi kesehatan manusia antara lain gangguan pernapasan, iritasi mata dan telinga, serta menimbulkan beberapa penyakit spesifik. Oleh karena itu pemantauan terhadap parameter ini perlu dilakukan. Pada banyak kasus penggunaan difussive sampler  dapat menghasilkan hasil yang valid dan merupakan metoda alternatif dengan biaya efektif apabila dibandingkan dengan metoda aktif. Oleh karena itu pengembangan mengenai alat ukur pasif ini dibutuhkan. Alat ukur pasif yang lazim digunakan merupakan alat ukur pasif yang seluruh bagiannya berasal dari luar negeri sehingga akses terhadap teknologi ini cukup terhambat baik dari sisi dana maupun kemudahan aplikasi. Dengan studi literatur yang cukup dan pengetahuan mengenai bahan material dan bahan kimia, segala bahan untuk bagian dari alat ukur pasif tersebut dapat didapatkan tanpa import. Bahan tersebut antara lain Teflon untuk tabung utama, stainless steel untuk mesh, polimer etilen untuk tutup tabung, dan PTFE untuk filter. Kemudian bahan tersebut dirakit dengan mencontoh Ogawa Passive Sampler. Dari hasil yg diperoleh presisi pengukuran alat ukur pasif berbahan berada dalam rentang 73-93% sedangkan rerata perbedaan dengan alat ukur pasif Gradko dalam rentang 20-42%.Kata kunci: Alat ukur pasif, bahan lokal, Ion kromatografi, Metode pemantauan pasif, OzonAbstract : The ozone compound which is in the troposphere layer is a pollutant that is harmful to human health such as respiratory problems, irritation of the eyes and ears, and also raises some specific diseases. Therefore, monitoring of these parameters is a need. In many cases the use of diffusive sampler can produce valid results and is an alternative method with a cost effective when compared with active methods.  Passive sampler commonly used is a passive sampler that all parts come from overseas so that access to this technology is quite constrained in funds and lack of application. With sufficient literature study and knowledge of materials and chemicals, all materials for passive sampler part can be obtained without import. Materials include Teflon for the main tube, stainless steel for the mesh, polymers of ethylene for the caps, and PTFE for the filter. Then the material is assembled with the example of Ogawa Passive Sampler. Results obtained from measurement of precision the local passive sampler in the range 73-93%, while mean of difference compared to Gradko passive sampler in the range 20-42%.Key words: Ion Chromatograph, local based materials, Ozone, Passive sampler

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

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.

Abstract

Limbah bahan berbahaya dan beracun (B3) yang dihasilkan di Indonesia setiap tahunnya mengalami peningkatan. Hal ini ditunjukkan dengan jumlah limbah B3 yang terus bertambah setiap tahunnya menjadi sekitar 200 juta ton pada tahun 2020. Makin besarnya limbah B3 ini makin memperbesar potensi bencana lingkungan jika tidak dikelola dengan baik. Pertambangan batu bara yang mendominasi aktivitas industri energi tidak terlepas dari permasalahan ini. Salah satu bisnis proses yang kerap terlupakan terkait pengelolaan lingkungan perusahaan pertambangan adalah proses pengangkutan. Oleh karena itu, penelitian ini akan menganalisis pengelolaan limbah B3 di salah satu fasilitas pengangkutan batu bara yaitu pelabuhan. Data primer pada penelitian ini didapatkan dengan melakukan observasi, wawancara, dan dokumentasi. Sedangkan data sekunder berupa data neraca limbah B3 laporan pelaksanaan pengelolaan lingkungan. Data yang telah didapatkan kemudian dilakukan evaluasi kesesuaian dengan peraturan mengenai pengelolaan limbah B3. Hasil identifikasi menunjukkan jenis limbah B3 yang mendominasi adalah oli bekas dan kemasan bekas B3. Kesimpulan dari evaluasi pengelolaan limbah B3 di lokasi studi yaitu di PT X telah dilakukan namun masih terdapat sedikit ruang untuk lebih baik di beberapa aspek pengelolaan limbah B3
