Abstract

This research objective examined the source of pollutants, water quality and water pollution level of Buyan Lake. The research conducted field observation to identify the source of pollutants, measuring the water quality and water pollution level of Lake Buyan compared to the standard of environmental quality and damage criteria. This research employed the newest standard measurement and equipment in purpose of water and wastewater inspection. Furthermore, this research used STORET method to analys the pollution level. The results discovered that the pollutant’s source was the settlement and agricultural activities around Buyan Lake. The average value of physical parameters i.e temperature, dissolved residue (TDS), suspended residue (TSS), turbidity and brightness are 23.02 oC; 127 mg.L-1, 4.71 mg L-1, 12.52 JTU; and 133.6 cm respectively. The average values ??of the chemical parameters i.e. pH, DO, BOD5, COD, NO3, NO2, Ammonia and Phosphate are 7.48, 5.95 mg.L-1*, 25.46 mg.L-1*, 42.99 mg.L-1*, 1.25 mg.L-1, 0.054 mg.L-1, 0.158 mg.L-1, and 0.149 mg.L-1 respectively. The average values ??of bacteriological parameters i.e Fecal Coliform and Total Coliform are 32.8 MPN/100 ml and 392 MPN/100 ml. The comparation results showed that DO, BOD5, COD, NO2, ammonia, phosphate, fecal coliform and total coliform exceed the Class I Standard of Water Quality. STRORET analysis confirmed a high level of pollution i.e. -40. The overall results show that Buyan Lake water is in the heavily polluted category due to domestic and agricultural activities. Keywords: Buyan Lake; Pollutant Sources; Pollution Level and Water Quality.

Abstract

Loloh air rebusan daun sirih merupakan obat tradisional Bali mengandung senyawa aktif Hidroksichavikol, memiliki aktivitas sebagai antioksidan dan antidislipemia. Dari hasil-hasil penelitian dilaporkan bahwa loloh air rebusan daun sirih mengandung senyawa aktif hidroksikavikol (HC). Senyawa aktif hiroksikavikol memiliki aktivitas sebagai antioksidan dan antidislipidemia. Sebagai anti oksidan dapat mengais ROS dan menghambat aktivitas radikal bebas. Sebagai antidislipidemia dapat menormalkan metabolisma lipid dengan menurunkan kadar kolesterol total, trigliserida, LDL dan VLDL serta meningkatkan kadar HDL serum darah. Stres oksidatif dan dislipidemia merupakan factor resiko utama penyakit jantung yang disebabkan oleh aterosklerosis. Aterosklerosis adalah terjadinya pembentukkan plak di dalam lumen pembuluh darah yang dipicu oleh sters oksidatif melalui disfungsi sel endotel, implamasi dan peroksidasi lipid. Stres oksidatif menyebabkan disfunsi sel endotel, meningkatkan kontraktilitas, pertumbuhan VSMC, invasi monosit dan peroksidasi lipid, inflamasi dan peningkatan pengendapan matrik protein ekstraseluler. Berdasarkan hal-hal tersebut disimpulkan bahwa HC loloh air rebusan daun sirih memiliki aktivitas sebagai antioksidan dan antidislipidemia untuk mencegah penyakit jantung.
