Penentuan Hasil Evaluasi Pemilihan Spesies Pohon Dalam Pengendalian Polusi Udara Pabrik Semen Berdasarkan Karakteristik Morfologi.

Abstract

The rapid development of the country in Indonesia, especially in the fields of industry and technology, is inseparable from the problem of air pollution, especially in the environment, namely pollutant gas and dust. Air pollution needs to be environmentally friendly by increasing the amount of vegetation or reforestation by planting tree species that have the ability to grow and absorb pollutant gases and absorb dust particles in polluted environmental conditions. The study uses descriptive analysis by assessing tree elements macroscopically to select the appropriate tree species and can be recommended as an absorber of gas pollutants and dust absorbers based on tree suitability scoring. The results showed that of 7 (seven) dominant tree species identified, there were 3 (three) dominant tree species that were very suitable, 3 (three) dominant tree species were suitable, and only 1 (one) dominant tree species were not suitable for air pollutant gas. Whereas the evaluation of the function of dust particle absorption shows that all dominant tree species studied have the appropriate criteria in absorbing dust with the acquisition of 65%-75% evaluation value.

Efforts in Controlling Coal Dust Hazards in the Stockpile Area of a Steam Power Plant (Pltu)

“…Reforestation by planting trees is an alternative solution that can help reduce dust pollution due to coal activities. Besides being able to produce oxygen, reforestation can absorb pollutants through its leaves (Azzahro et al, 2019). The Figure 3 shows the reforestation conditions carried out by PT.…”

Evaluasi fungsi tata hijau pada tempat pemrosesan akhir (TPA) Tlekung, Kota Batu

“…Menurut Azzahro et al (2019), pohon yang sangat sesuai dalam menyerap gas polutan diantaranya akasia (Acacia mangium), angsana (Pterocarpus indicus), dan kihujan (Samanea saman). Spesies tersebut mempunyai ciri-ciri fisik yang menunjang dalam penyerapan polutan diantaranya memiliki daun yang tipis dan berjumlah banyak.…”

Types of Shade Plants As Efforts to Increase Students' Knowledge and Attitudes for Conservation

“…The type of pollution that requires systematic and comprehensive handling is pollution that is mostly produced by human activities such as Vol 1 No 2 2022 (70-74) burning motor vehicle fuel. In general, the ecological functions of road shade plants are (1) as city lungs because these plants produce oxygen gas needed by all living things, (2) as absorbents of toxic gases/particles to reduce air pollution, (3) as noise absorbers and (4) as bird habitat [5].…”

“…Not all types of plants can be used as road shade plants, as road shade plants there are certain conditions that must be met [6] said the characteristics of good shade trees planted include: (1) better absorption of CO2 and lead gases; (2) can produce Oxygen; (3) tree height is more than two meters but not more than 12 meters; (4) lush with leaf density that can cover the sun's rays; (5) broad canopy or able to cover a large area; (6) maintenance is easy; (7) the branches are not easily broken when blown by strong winds; (8) twigs or branches are not too large, because it is dangerous if they fall and fall on people who are under them; (9) strong roots into the ground so that trees do not fall easily when blown by strong winds, roots do not come out to the surface which can damage floors and walls of houses or sidewalks.…”
