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

Production of sengon continuously improved to meet the needs of the timber industry, but increased production sengon still face the problem of that disease gall rust fungus Uromycladiumtepperianum Sacc. that is causing inhibited growth of sengon, so it needs to be eco-friendly controlled by spraying fungicide from mindi leaves which contains active ingredient azadirachtin and margocyn as antimicroorganisms. The research was conducted by using Factorial Completely Randomized Design with 2 factors and 3 replications. Priming factors (A) consisted of A0 (control), A1 (immersion), and A2 (humidification). Fungicide factors (B) consisted of B0 (control), B1 (100 grams of Mindi leaves / 2L water), B2 (150 grams of mindi leaves/2L water), B3 (200 grams of mindi leaves/2L of water), and B4 (250 grams of mindi leaves/2L water). Fungicide was given every 7 days after inoculation with 7 times of applications. The results of the research proved that the treatment A2B3 (priming with humidification and fungicides 200 grams of mindi leaves/2L of water) was an effective treatment in reducing the intensity of gall rust disease on sengon with 8,36% of intensity.
