Abstract

Telah dilakukan penelitian tentang korelasi kadar ion logam Pb terhadap kandungan protein pada kerang darah (Anadara granosa) yang diambil di pantai Muara Badak Kalimantan Timur. Penelitian ini bertujuan untuk mengetahui kadar ion logam Pb dan kadar protein pada kerang darah berdasarkan ukuran dan lokasi sampel yang berbeda. Korelasi kadar ion logam Pb dan protein pada kerang darah diuji menggunakan metode Least Square dan product moment Pearson. Analisis kadar ion logam Pb menggunakan SSA (Atomic Absorption Spectrophotometer) dan analisis kadar protein menggunakan metode Kjeldahl. Pada penelitian ini didapatkan kadar ion logam Pb di pelabuhan umum Desa Muara Badak Ilir, Desa Salo Palai dan PT Pier .VICO Indonesia dengan rata-rata masing-masing sebesar 0,891 mg/L, 0,968 mg/L, dan 0,602 mg/L. Kandungan protein kerang darah di Desa Muara Badak Ilir, Desa Salo Palai dan PT Pier .VICO Indonesia dengan rata-rata masing-masing sebesar 20,4308%, 22,7810% dan 18,0098%. Korelasi kadar logam Pb terhadap kadar protein kerang darah (Anadara granosa) dinyatakan positif dengan hasil koefisien korelasi kuat (r = 0,9130).Kata kunci: Logam Pb, Protein, Kerang Darah (Anadara granosa)

Abstract

Blood cholesterol level which were higher than normal is a trigger of various diseases. The objective of the research was to know the anti-hypercholesterol effect of bark African plant. The research about utilization of ethanol extract of bark African plant (Vernonia amygdalina Delile) has been done, it proved could decrease total cholesterol levels in male mice (Mus musculus). In this research sample macerated with ethanol 96% and then concentrated by rotary evaporator, and gained 9,7% of yield. Based on the results of phytochemical test, secondary metabolites compound that contained in bark African plant are alkaloid, flavonoid, triterpenoid, steroid, phenolic and saponin. On antihiperkolesterolemia activity test by using male mice, there are several treatments that negative control (-), positive control (+) and three treatment with different doses i.e. a low doses (7.5 mg/kg BB), middle doses (15 mg/kg BB) and high doses (30 mg/kg BB). The parameter measured was blood serum of male mice by using a Cholesterol Test Strips. From this test it showed that the effectiveness of decreased total cholesterol level at middle doses of 15 mg/kg BB. Keywords: Bark African plant (Vernonia amygdalina Delile), Phytochemicals test, Total cholesterol levels, Cholesterol test strips
