Relationship Between Waist Circumference with HS-CRP (High Sensitivity C-Reactive Protein) Levels in Men
Get PDFHigh-sensitivity C-reactive protein (hs-CRP) levels are inflammatory markers that can be influenced by visceral adipose tissue, especially since sex hormones also influence fat storage patterns and the incidence of central obesity. This study examined the relationship between waist circumference and hs-CRP levels in men. This study used an analytical observational study type with a cross-sectional approach. Statistical analysis of 24 samples using the non-parametric Rank-Spearman test obtained a significance value (p < 0.05); r = 0.763. This study shows a significant relationship between men's waist circumference and Hs-CRP levels. Further research can pay attention to variables that can increase Hs-CRP levels, such as physical activity, food intake, other infectious diseases, and examination of blood glucose, cholesterol, and blood pressure levels
A Purification Process of Wosting Oil Using CaO Adsorbent Based on Blood Shell Shells (Anadara granosa)
Get PDFBlood clam shells are inorganic materials rich in content obtained from heating at high temperatures, so they can be used as adsorbent. The purpose of this study is to determine the effect of calcination temperature of blood clam shell adsorbents, used to test the quality of used cooking oil (wosting oil). In this study, three calcination temperature variations were used, namely 800 ℃, 900 ℃ and 1000 ℃ for 2 hours each. Then the quality of adsorbent was tested by knowing oxide element with SEM. The adsorption process was carried out using the contact method by immersing the adsorbent in wosting oil for one hour. Wosting oil that has been adsorbed is then tested for quality, namely: free fatty acid content, peroxide number, water content, viscosity, density, physical properties (odor and color). The results obtained are: The best quality of adsorbent was obtained at a calcination temperature of 1000 ℃ which was analyzed through three parameters namely, content, density value and surface area. The best quality of wosting oil is obtained in used cooking oil with 3 times heating with calcined adsorbent at 1000 ℃ which is analyzed based on several parameters as previously explained

Ant species found in the rice field near the mining area included Leptogenys chamela (44 individuals), Solenopsis invicta (4 individuals), and Camponotus texanus (8 individuals). In contrast, in the rice field farther from the mining area, seven species were found: Solenopsis invicta (5 individuals), Myopias emeryi (71 individuals), Tetraponera rufonigra (37 individuals), Paraponera clavata (7 individuals), Leptogenys chamela (5 individuals), Dolichoderus sp. (1 individual), and Camponotus texanus (13 individuals). Ant abundance was higher in the rice field located farther from the coal mining area compared to the one located nearby
Physical Processing of Various Forage Plants and Their Application in Aquafeed Development
Get PDFFeed is a crucial element in aquaculture, directly influencing the growth and reproduction of aquatic organisms. This study aims to explore the potential of forage-based ingredients as alternative feed sources to reduce reliance on costly conventional inputs such as fish meal. Various locally available forages, including aquatic plants (Azolla sp., Lemna sp., and water hyacinth), tree legumes (leucaena and calliandra), and tuber crops (cassava leaves), were evaluated based on their nutritional composition and feasibility for use in aquafeed. Processing methods such as physical (drying, grinding, pelletizing), chemical (acid and enzyme addition), and biological (fermentation using Aspergillus niger or rumen enzymes) treatments were applied to enhance digestibility and reduce antinutritional factors. Analytical assessments showed that these treatments significantly lowered crude fiber content while increasing protein concentration and improving palatability. Fermented leucaena leaves and azolla powder, for instance, demonstrated improved nutritional profiles and potential for inclusion in practical feed formulations. The study concludes that forage-based feed processing improves feed efficiency and supports sustainable, low-cost aquaculture. Continued innovation in forage processing technology is recommended to support national feed self-sufficiency goals and promote environmentally friendly aquaculture practices
Bio-Reclamation Evaluation of Former Gold Mine Land: Pre- and Post-Reclamation Soil Management Conditions
Get PDFFormer gold mining land, especially those abandoned without reclamation, experiences serious physical, chemical, and biological degradation, and is potentially contaminated with heavy metals such as mercury (Hg). This study aims to evaluate the effectiveness of organic farming-based bioreclamation and good soil management, using dwarf elephant grass (Pennisetum purpureum) and chicken manure in improving the condition of former gold mining land. The parameters analyzed include physical, chemical, and biological properties of the soil, as well as mercury levels in the soil and plants. The results showed that the soil quality index increased from 0.32 (low) to 0.62 (good). The organic C content increased from 0.91% to 2.16%, soil pH increased from 3.53 to 5.03, and the availability of phosphorus and potassium also increased. The population of methyl mercury-reducing bacteria increased 22.4 - 58.2 times, indicating improved microbial adaptation to the environment. Mercury content in plant tissue decreased drastically from 11.60 mg/kg to 0.11 mg/kg or a decrease of 99.05%, although still slightly exceeding the threshold. The conclusion is that reclamation with an organic approach and effective soil management not only improves soil fertility and quality, but also reduces the risk of heavy metal poisoning
