Abstract

This study aims to determine how much the ability of Pandan Wangi (Pandanus amaryllifolius Roxb.) Plants to accumulate phosphate laundry waste from Kendari City and to determine the phytoremediation mechanism of laundry waste by calculating the bioconcentration factor (BCF) and translocation factor (TF) phosphate in Pandan plant was planted on media with varying concentrations of laundry waste. This type of experimental research was prepared based on the Completely Randomized Design (CRD) pattern consisting of control P0 (1,000 mL water) and 4 treatments: P1 (250 mL laundry waste + 750 mL water), P2 (500 mL laundry waste + 500 mL water), P3 (750 mL laundry waste + 250 mL water) and P4 (1,000 mL laundry waste). Data were analyzed using Analysis of Variance (ANOVA). The results showed that the largest accumulation of laundry waste phosphate in Pandan Wangi plants was in treatment P4 (0.071%), then P3 (0.063%), P2 (0.061%), P1 (0.059%) and P0 (0.055%). Based on the Anova test, the average of each treatment was not significantly different from the control of laundry waste phosphate accumulation.

Abstract

The quercetin flavonoid content in cherry leaves and Moringa serves as a competitive inhibitor of hypoxanthine and xanthine which causes uric acid not to form. The purpose of this study was to determine the effect of grains of cherry leaves and Moringa leaves on the uric acid levels of mice. 25 male mice weighing 20-30 grams 2-3 months old were divided into 5 treatment groups, namely: K1 as a negative control (without treatment), K2 as the positive control (chicken liver juice 0.5 mL), K3 (cherry leaf juice and liver juice chicken), K4 (Moringa leaf juice and chicken liver juice) and K5 (a mixture of cherry leaf juice, Moringa, and chicken liver juice). Mice are first measured initial uric acid levels. The administration of chicken liver juice at a dose of 0.5 mL is done three times a day for 7 days so as to achieve a hyperuricemia condition. Furthermore, the juice was given according to the treatment group at a dose of 0.2 mL for 14 days and finally, uric acid levels were calculated. Data were analyzed by ANOVA and LSD test (α = 0.05). The results showed that the administration of cherry leaves and moringa juice significantly reduced blood uric acid levels in mice in all treatment groups. The highest mean decrease in uric acid levels was in the K5 (0.91 mg / dL) group, compared with K1 (0.93 mg / dL), K2 (2.03 mg / dL), K3 (0.994 mg / dL) and K4 (0.98 mg / dL) .Keywords:  Uric Acid Levels, Hyperuricemia, Munitingia calabura L, Moringa oleifera L. AbstrakKandungan flavonoid golongan kuercetin pada daun kersen dan kelor berfungsi sebagai inhibitor kompetitif hipoxantin dan xantin yang menyebabkan asam urat tidak terbentuk. Tujuan penelitian ini untuk mengetahui pengaruh pemberian perasan daun kersen dan daun kelor terhadap kadar asam urat mencit. 25 ekor mencit jantan berat 20-30 gr berumur 2-3 bulan dibagi kedalam 5 kelompok perlakuan yaitu: K1 sebagai kontrol negatif (tanpa perlakuan), K2 sebagai kontrol positif (jus hati ayam 0.5 mL), K3 (perasan daun kersen dan jus hati ayam), K4 (perasan daun kelor dan jus hati ayam) dan K5 (campuran perasan daun kersen, kelor dan jus hati ayam). Mencit terlebih dahulu diukur kadar asam urat awal. Pemberian jus hati ayam dengan dosis 0.5 mL  dilakukan tiga kali sehari selama 7 hari sehingga mencapai kondisi hiperurisemia. Selanjutnya diberi perasan sesuai kelompok perlakuan dengan dosis 0.2 mL selama 14 hari dan dihitung kadar asam urat akhir. Data dianalisis dengan ANOVA dan uji BNT (α=0,05). Hasil penelitian menunjukkan bahwa pemberian perasan daun kersen dan kelor secara signifikan menurunkan kadar asam urat darah mencit pada semua kelompok perlakuan. Rerata penurunan kadar asam urat tertinggi terdapat pada kelompok K5 (0.91 mg/dL), dibandingkan dengan K1 (0.93 mg/dL),  K2 (2.03 mg/dL), K3 (0.994 mg/dL) dan K4 (0.98 mg/dL).Kata kunci : Kadar Asam Urat, Hiperurisemia.,Munitingia calabura L, Moringa oleifera L.

Abstract

ABSTRACTThis study aims to determine the effect of MSG to the microscopic structure of the ovaries of mice. This study was a experimental study using a completely randomized design (CRD). A total of 16 female mice aged 3 month were devided into 4 groups namely P0 (Control), P1 (0,012 mg/gr BB), P2 (0,015 mg/gr BB) and P3 (0,018 mg/gr BB), MSG administration carried out of 14 days. On day 15 the animals were sacrificed and performed organ harvesting ovaries to make histological preparations. Observation were made by observing the histological structure of the ovaries , and count the number of primary follicles, secondary, tertiary, the korpus luteum and follicular atretic. Data were tested with ANOVA, and LSD (α=0,05%). The result showed the existence of structural damage in the form of a gap between the ovarian follicular granulosa cells and ovarium follicle diameter reduced with increasing doses of MSG given. MSG administration also decreases the average number of follicles in all treatment doses, but the mean of the highest drop in the number of follicles present in treatmen P3 that is, the number of primary follicles (2,50), secondary follicles (2,25), tertiary follicles (1,25) and follicular atretic (4,25), while the corpus luteum is not found.Keywords : Monosodium glutamate, Damaged Structure of The Ovaries, Mice (Mus musculus,L)
