Abstract

The number of national parks in Indonesia increased rapidly since 1982. Support from local people plays an important role in sustaining national parks, therefore their needs, aspirations and attitudes should be considered to assure better national park management. This research was intended to discern the knowledge, perception and attitude of local people residing close to Kerinci Seblat National Park towards the park and its conservation initiatives, to identify factors affecting them, and to determine if local communities perceived more benefit from the park were likely to support it. Knowledge of local people about the existence of the park and regulation governed it was high. However, knowledge of local people about its function and benefit for society was relatively low. Attitudes of local people on the park and its conservation initiatives was affected by many factors including their involvement in an organization, administrative residence affiliation (district), ethnic, formal education attainment, distance of residence to national park, income, family size, affluence, and agricultural land ownership. Almost all of the local people perceived that the park did not give them economic benefit directly, therefore they expected to be involved in planning and making use of it. They also perceived that it was needed to conserve natural resources and supply ecological services. However, most of the people perceived that their lives did not depend on the park, so its existence should not be guarded collectively.

Abstract

Biological methods have gained attention as an alternative treatment for oil degradation in pollution remediation. External and internal factors have a great influence on crude oil biodegradation. This experiment studied the effect of oil concentrations and ratios of Ammonium and Phosphate on oil degradation in mixed cultures of local strains of Pseudomonas aeruginosa and Arthrobacter simplex. The oil degradation ability of this mixed culture was compared to the dormant culture of Epyzim. The increase of oil concentration, from 1, 3, 5 and 10% (w/v), significantly lowered the ability of both cultures to degrade the oil i.e from 83 % for 1% oil concentration to 64% for 10% oil concentration using local strains. The local strains showed better capability compare to the dormant culture. Medium composition was designed by three levels of ammonium concentration (7.6, 37.9 and 75.8 mg l-1) and two levels of phosphate concentration (2.0 and 9.9 mg l-1). The ratio of ammonium to phosphate of 3.8:1.0 in the growth media has resulted the maximum level of oil degradation, i.e 83% and 88%, for dormant and local cultures respectively. The results suggest a potential usage of local microorganisms in degrading crude oil-polluted water.
