Penelitian bertujuan untuk menganalisis kadar cemaran logam berat pada sedimen air sungai di Jawa Tengah (Kaligarang, Juwana, Bengawan Solo, Kali Agung, Kali Banger). Sampel penelitian berupa sedimen sungai. Sampel diuji kadar logam berat (Hg, Cd, Cu, Cr, Zn, Pb). Uji kadar logam berat dilakukan dengan menggunakan metode Mercury analycer (Hg) dan AtomicAbsorptionSpectroscopy (Cd, Cu, Cr, Zn, Pb). Hasil pengujian menunjukkan, kadar logam tertinggi adalah Zn dan Cu. Kadar logam Zn dari sumber cemaran industri makanan, farmasi, rumah tangga, peleburan timah, pembuangan oli, limbah minyak dan limbah batik secara berturut-turut sebesar 254,12 ppm; 211,65 ppm; 151,56 ppm; 112,02 ppm; 124,65 ppm; 127,42 ppm dan 133,417 ppm. Kadar logam Cu dari sumber cemaran yang sama selain limbah farmasi berturut-turut sebesar 49,78 ppm; 30,77 ppm; 30,01 ppm; 27,98 ppm; 16,20 ppm dan 25,70 ppm. Untuk industri farmasi, kadar logam tertinggi kedua adalah Pb yaitu sebesar 57,40 ppm. Disimpulkan bahwa dari semua jenis sumber cemaran yang masuk ke badan air sungai sebagian besar mengandung logam Zn dan Cu. Secara keseluruhan kadar Hg, Cd, Cu, Zn, Cr, dan Pb cukup tinggi. Perairan sungai dalam penelitian ini, pada saat pengamatan menerima masukan limbah yang mengandung Zn lebih banyak dibandingkan logam lain.

Indigenous bacteria are able to remove the metals contamination in environment. This study aimed to assess the resistance of bacterial species to Zinc (Zn) in Banger River, Pekalongan City. The bacteria from three different parts of Banger River were isolated and inoculated in Zn-selective medium. Then, molecular identification to determine the bacteria species was conducted using polymerase chain reaction (PCR) by applying forward-reverse 16SrRNA gene primers. The sequences analysis was conducted using MUSCLE and MEGA6. There were seven dominant species that possibly resistant to Zn. Approximately, every isolate could reach more than 95 % from 2000 ppm of Zn in the medium. The higher absorption of Zn was found in Z5 isolate. The seven bacteria species were clustered into nine genera i.e. Klebsiela, Xenorhabdus, Cronobacter, Enterobacter, Escherichia, Shigella and Sporomusa known as Gram Negative bacteria and Clostridium and Bacillus as Gram Positive bacteria. In Gram Positive bacteria, especially Bacillus sp, carboxyl group in peptidoglycan play a role as metal binder. In Gram-negative bacteria, lipopolysaccharide (LPS) which is highly anionic component on the outer membrane, able to catch the Zn. Besides that, Enterobacter activates endogen antioxidants such as glutathione peroxidase (GSHPx), glutathione reductase (GR), catalase (CAT) and superoxide dismutase (SOD). The research found there was possible seven novel indigenous bacteria species in Banger that able to remove Zn from the sediment extremely. This finding can be developed as an eco-friendly approach to reduce metals pollution using local microorganisms.

Cardiovascular disease caused by hyperlipidemia is the highest case in term of fatality of non-infectious disease in Indonesia. Cnidoscolus chayamansa is well known as a herb that has nutraceutical potential for medicine and likely as a hypolipidemia agent. Therefore, this study aimed to identify the optimal dose of C. chayamansa as a candidate to treat cardiovascular diseases. A total of 30 white rats were acclimatized in the laboratory for 14 days. After that, the rats were grouped into six groups, randomly, which including a healthy control group (K0), a negative control group or hyperlipidemic rats (K-), a positive control group or hyperlipidemia-induced rats that was supplemented with atorvastatin (K+), then a hyperlipidemic rats treated with alcoholic extract of C. chayamansa leaves at doses of 100 mg /kgBB /day for K1, 200 mg/ kgBB/ day for K2 and 400 mg/ KgBB/ day for K3. The results showed that K3 treatment is the most effective and optimum dose for lowering total cholesterol level at 76.81±1.10 mg/dl, triglycerides 72.39±1.66 mg/dl and LDL-C at 21.47±0.58 mg/dl. The aortic histology assessment also showed that the K- group had putative thrombus or plaque in intima, and it was not found in other groups. This research focused on the optimum dose and new usage of C. chayamansa, as an anti-inflammatory in atherosclerosis. By understanding the optimum dose of C. chayamansa, the community can apply and control the herb consumption for their own therapeutic properties. For future application, the herb is potentially developed as anti-atherogenic medicine.

The diversity of intestinal bacteria in geese correlates with environmental conditions, rearing methods, and consumed feeds. The intestinal bacteria composition is useful for the absorption of nutrition, improving the metabolism, and may be related to the immune system. This study was conducted to examine the intestinal bacteria composition and the diversity of maintained goose in aviaries and barns. This research was an observational exploratory. Five geese were taken purposively from local breeders in Gunungpati District, Semarang City. A total of 5 g of intestinal contents from each sample was used for microbial genome isolation. Then, the genome was amplified to collect 16S rRNA gene region V3-V4. The amplicons were then sequenced using the next generation sequencing (NGS) method (Illumina high-throughput sequencing; paired-end reads) and analyzed using QIIME2 to identify bacterial species. In addition, GC-MS was performed to identify and measure fatty acid contents in the intestinal. The results showed that both rearing and caged goose contained nine phyla of intestinal bacteria. The number of intestinal bacteria of barn geese (SU) reached 32,748 Operational Taxonomy Units (OTU); higher than aviary geese (SK), which was 11,646 OTU. The intestinal bacteria community in barn geese was approved by Phylum TM7 (Saccharibacteria candidate) (53.18%), followed by Firmicutes (32.51%) and Bacteriodetes (5.42%). Whereas on SK Firmicutes was compiled 49.3 4% of total OTU, TM7 (S. candidate) up to 21.17%, and Actinobacteria up to 15.99 %. The abundance of TM7 may contribute to high 9,12-octadecadienoic acid production, while Firmicutes was related to the high production of oleic acid. Based on these data, the reared geese had a more abundant diversity of bacteria than the caged one.
