Abstract

Bougainvillea leaves are often used by the public as a treatment by drinking boiled water, but their use as a blood sugar-lowering agent is not supported by scientific data. The purpose of this study was to determine the effect of reducing blood glucose levels and to determine the dose of extract that is effective in in white rats. The plant's herbal extract was prepared using the reflux method with 90% ethanol solvent. This study uses a laboratory experimental method to compare blood glucose levels in white rats before and after administration of herb extract at doses of 100, 200, and 300 mg/kg BW orally using high-fat feed induction and streptozotocin. Blood glucose levels were measured using a glucometer, and mice were declared positive for diabetes with fasting blood sugar levels above 126 mg/dL. The number of test animals used in this study was 30 mice, divided into 6 groups. A randomized block design was used as the research design. The study's findings revealed that administering Bougainville spectabilis willd herb extract at doses of 100, 200, and 300 mg/kg BW can reduce blood glucose in test animals with an effective dose of 200 mg/kg BW

Abstract

Banana tape is one of the innovations in processing bananas into new processed products that can be enjoyed by the community, which is almost the same as making tape in general. The purpose of this study was to determine the right variation of ragi concentration on the physical and chemical characteristics of kepok banana tape. This type of research is experimental with the Completely Randomized Design (RAL) method with variations in ragi concentration, namely 0.5 grams, 1 gram, 1.5 grams, 2 grams and 2.5 grams with a fermetation time of 3 days. The parameters of this study include physical analysis (taste, flavor, color and texture) and chemical analysis (glucose, alcohol and pH). The results showed that ragi concentration of 0.5 gram produced the best organoleptic test of taste 3.75, aroma 3.4, color 3.6 and texture 3.45. Chemical tests showed that a ragi concentration of 1.5 grams produced the best results in glucose levels of 7.9%, alcohol 1.24% and pH 4.41. This study has the potential to be used as a contextual chemistry learning medium, particularly in understanding fermentation processes, pH changes, and biochemical transformations in everyday food products.

Abstract

In the batik industry, synthetic dyes such as indigosol blue are more commonly used than natural dyes. However, water pollution resulting from the batik industry is a serious issue that can threaten water quality and be harmful to human health. This research uses the adsorption method with kapok fruit peel as the adsorbent to address the problem of Indigosol blue dye. The kapok fruit peel is pyrolyzed at temperatures of 400 °C, 450 °C, and 500 °C. This study aims to determine the effectiveness of kapok fruit peel biochar in the adsorption of indigosol blue dye with variations in weight, time, and pH. The results show that the characteristics of kapok fruit shell biochar include moisture content at temperatures of 400 °C, 450 °C, and 500 °C, which are 7.40 %, 6.40 %, and 5.20 %, respectively. The ash content of kapok fruit shell biochar at temperatures of 400 °C, 450 °C, and 500 °C was 8.70 %, 6.10 %, and 5.40 %, respectively. The maximum weight of kapok fruit shell biochar in absorbingindigosol blue dye was 75 mg with an adsorption capacity of 0.986 mg/g. The maximum contact time required was 40 minutes with an adsorption capacity of 0.626 mg/g. The maximum pH of indigosol blue dye in the adsorption process occurred at pH 7 with an adsorption capacity of 1.709 mg/g. These findings indicate that kapok fruit shell biochar has potential as an environmentally friendly alternative adsorbent for treating batik industry wastewater.

Abstract

Synthetic dyes such as remazol red are commonly used in the batik process, but their residual waste is a major contributor to water pollution. These effluents can degrade water quality, damage aquatic ecosystems, and pose health risks to humans. This research aims to reduce these problems by using an adsorption method that utilises kapok randu branch as an adsorbent for remazol red dye. Kapok randu branches were pyrolysed at temperatures of 400 °C, 450 °C, and 500 °C. This study aims to measure the ability of biochar from kapok randu branches to adsorb remazol red dye under varying weight, time, and pH conditions. The results showed the characteristics of kapok randu branches biochar include moisture content of 400 °C, 450 °C and 500 °C biochar of kapok randu branches of 5.56 %, 5.01 % and 4.80 %, respectively. The ash content of the 400 °C, 450 °C, and 500 °C kapok randu branch biochar was 5.68 %, 6.66 %, and 7.24 %, respectively. The maximum weight of kapok randu branch biochar in adsorbing remazol red dye is 25 mg with an adsorption capacity of 0.312 mg/g. The maximum contact time required was 60 minutes with an adsorption capacity of 1.004 mg/g. The maximum pH for the remazol red dye during the adsorption process was at pH 4, with an adsorption capacity of 5.816 mg/g.
