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.

Abstract

Herce Farida Solossa 20.2018.2.00117 Mapping of Groundwater Hardness Distribution of Drinking Water for Bangkalan District Community, in 2019. Thesis, Department of Environmental Engineering, Faculty of Civil Engineering and Planning, Adhi Tama Institute of Technology Surabaya, Advisor Dr. Yulfiah, ST., Msi.              Water hardness is the content of certain minerals in water, generally calcium (Ca) and magnesium (Mg) ions in the form of carbonate salts and this content if it exceeds quality standards can have an impact on human health. The purpose of this study is to map the distribution of groundwater hardness as a source of water supply in Kab. Bangkalan. The sample of this study is shallow wells with a depth not exceeding 20 m. This type of research is a descriptive study with a qualitative and quantitative approach. The research sample was taken as many as 18 following the number of subdistricts in Kab. Base Samples taken are water source wells used by the community. Sampling time is the dry season. Samples taken are stored in bottles and immediately taken to the laboratory for examination. Sampling locations are made in the form of maps with the ArcGis application. The conclusion of this research is that the level of hardness in groundwater in Kab. Base has moderate value - maximum. The distribution of hard water is also evenly distributed throughout the Kab. Base with the maximum distribution from east-west to east and east-east while the hardening is starting from north and northeast to south, southwest and west. This suggestion that can be made is that residents who use shallow wells should use a filter and cook it first for drinking needs.

Abstract

The decrease in air quality becomes one of the development impacts that must be controlled deliberately. Planting trees is crucial for reducing the total number of dust and gas pollutants as it can restrain air pollution through absorption and adsorption. This research aimed at (a) determining the most appropriate types of plants for controlling air pollution and (b) developing software to plan the need for Green Open Space (GOS) in the urban city. The criteria of assessment for measuring the ability of a plant to absorb pollutant gas consisted of: (a) the density level of tree-crown, (b) plant combination, (c) thickness level of leaf, (d) the total number of leaves, and (e) plant distance. Meanwhile, the criteria for assessing the ability of the plant to adsorb dust particles comprised: (a) the roughness of leaf surface structure, (b) leaf width, (c) density level of tree-crown, (d) texture of stem skin surface, and (e) density level of the twig. The results of the research demonstrated that plants of Angsana (Pterocarpus indicus), Kihujan (Samanea saman), and Acacia (Acacia auriculiformis) were very appropriate for absorbing pollutant gas. Meanwhile, the good plants for adsorbing dust particles involved Angsana, Kihujan, Acacia, Tanjung (Mimusops elengi), Kersen (Mutingia calabura), Ketapang (Terminalia cattapa), and red Dadap (Erythrina crista-galli) by the level of adsorption ability around 65-75%. The successfully developed software could present suitability between Green Open Space (GOS) calculated manually and the one counted by software.
