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

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

Abstract

AbstrakKelurahan Sukarame, Kota Bandar Lampung merupakan salah satu kelurahan dengan jumlah kepadatan penduduk yang tinggi diiringi dengan peningkatan timbulan sampah setiap tahunnya.  Pemerintah telah telah menyediakan fasilitas dan infrastruktur dalam mengelola sampah namun Kelurahan Sukarame masih memiliki probelmatika dalam penggunaannya seperti banyaknya TPS Ilegal. Hal tersebut mengindikasi bahwa terdapat permasalahan pada kesadaran dan kurangnya pemahaman masyarakat dalam pengelolaan sampah hingga pemanfaatan fasilitas pengelolaan sampah di Kelurahan Sukarame. Oleh karena itu, edukasi dan sosialisasi terkait pengelolaan sampah perlu dilakukan terhadap stakeholder atau tokoh masyarakat di Kelurahan Sukarame seperti ketua-ketua Rukun Tetangga (RT) atau Rukun Warga (RW). Kajian dasar yaitu mengidentifikasi timbulan, densitas, dan komposisi sampah mengacu pada SNI 19-3964-1994. Karakteristik sampah (kelembapan dan niai kalor) akan diidentifikasi melalui formula empiris berdasarkan komposisi sampah. Sosialisasi diberikan kepada peserta perwakilan Kelurahan Sukarame. Keberhasilan sosialisasi teridentifikasi melalui 10 pertanyaan sederhana terkait konsep dasar persampahan. Hasil timbulan sampah yang didapatkan di Kelurahan Sukarame sebesar 0,08±0,02 kg/orang/hari atau 0,24±0,05 L/orang/hari. Komposisi sampah teridentifikasi adalah 73% sampah organik biodegradable, diikuti dengan sampah plastik 26,5%. Karakteristik sampah memiliki kelembapan relatif 47% dan nilai kalor 3.097 Kkal/kg. Pewadahan sampah disarankan menggunakan wadah terpilah tiga jenis sampah (organik, plastik, dan lainnya). Pengolahan sampah yang dianjurkan adalah pengolahan dengan metode komposting secara individual/komunal (sampah organik), pirolisis (sampah plastik), dan bank sampah atau TPS3R untuk pengelolaannya. Hasil sosialisasi ditemukan bahwa lebih dari 50% peserta memiliki peningkatan pemahaman dan berhasil teredukasi. Kata kunci: sosialisasi; pengelolaan sampah; kelurahan sukarame; timbulan sampah AbstractSukarame Subdistrict, Bandar Lampung City is one of the subdistricts with a high population density accompanied by an increase in waste generation every year. The government has provided facilities and infrastructure for managing waste, but Sukarame Village still has problems with its use, such as the number of illegal TPS. This indicates that there are problems with community awareness and lack of understanding in waste management and the use of waste management facilities in Sukarame Village. Therefore, education and outreach regarding waste management needs to be carried out among stakeholders or community figures in Sukarame Village, such as the heads of the Neighborhood Association (RT) or Community Association (RW). The basic study is identifying waste generation, density and composition referring to SNI 19-3964-1994. Waste characteristics (moisture and heat value) will be identified through empirical formulas based on waste composition. Socialization was given to participants representing Sukarame Village. The success of socialization was identified through 10 simple questions related to basic waste concepts. The waste generation results obtained in Sukarame Village were 0.08 ± 0.02 kg/person/day or 0.24 ± 0.05 L/person/day. The identified waste composition is 73% biodegradable organic waste, followed by 26.5% plastic waste. The characteristics of the waste have a relative humidity of 47% and a calorific value of 3,097 Kcal/kg. It is recommended that waste containers be used in containers separated by three types of waste (organic, plastic, and others). The recommended waste processing is processing using individual/communal composting methods (organic waste), pyrolysis (plastic waste), and waste banks or TPS3R for management. The results of the socialization revealed that over 50% of participants experienced an improvement in understanding and were successfully educated. Keywords: socialization; waste management; sukarame subdistrict; solid waste production

Abstract

One of the most widely used fuels is coal, where the South Sumatra region is an area with coal potential whose production is still being increased. On the other hand, there are negative impacts caused by coal exploration activities, one of which is mining runoff, commonly called acid mine drainage. Acid mine drainage has a low pH and contains inorganic constituents such as iron and manganese. Therefore, proper and optimum information processing is needed to support environmentally friendly mining management. In contrast, alternative materials such as blast furnace slag, wood ash, fly ash, cement kiln dust, and construction waste are being used. These materials are effective against AMD, at a relatively low cost, and outperform traditional neutralizers. However, comparing them with conventional agents is challenging due to limited data and experimental variation. In this study, the objectives to be achieved are 1) to determine the quality conditions of AMW at the study location, 2) to determine the effectiveness of the use of chemical and alternative compound neutralization agents in the processing process, and 3) to provide recommendations for the dosage, type of neutralization agent, and the most optimum time in AMW processing. The AMW obtained is then subjected to laboratory analysis related to quality, including TSS, pH, Fe, and Mn parameters. In addition, conventional and alternative neutralization agents are also prepared and then used to process AMW. Then, experiments were carried out on variations in the type of neutralization agent, the dosage of neutralization agent use, and the contact time between the neutralization agent and AMW. Experimental results have shown that these materials, mainly pond ash and concrete sludge, can effectively neutralize pH and reduce Mn concentrations by up to 83.26% and 79.12%, respectively. Similarly, Fe concentrations can be reduced by up to 80.76% and 74.05% using pond ash and concrete sludge, respectively. While these results are promising, future research should focus on characterizing the generated sludge to confirm the adsorption of ferrous and manganese ions onto the surface of the alternative neutralizers.

Abstract

Climate change that is happening at this time affects the decrease in the availability of water in the world. Urban areas, especially coastal areas, will have a more significant impact on water scarcity. Coastal areas in Indonesia, such as Bandar Lampung City, are mainly concerned in this study. Therefore, a study was conducted to determine the variables that influence water conservation practices in Bandar Lampung, which focuses on social psychological factors with four independent variables. By knowing the independent variable that has the highest level of influence, an approach to conservation efforts at the individual level can be approached. Data were obtained using a closed questionnaire with answer options using a Likert scale. Data analysis used simple linear regression and stepwise regression. The simple linear regression results show that the variable social norms (X4) are the highest variable with a value of R2 0.0385. In stepwise regression, the variable attitude towards conservation (X1), the benefits obtained (X2), individual control behavior (X3), and social norms (X4) simultaneously have a coefficient of determination value of R2 0.06127, where the social norms variable align with sample linear regression results on water conservation practices. These social norms can be used as a reference by stakeholders such as Perumda, Regional Government, NGOs, etc., through individual approaches in mapping strategies for increasing water conservation practices.
