Abstract

Fish is a commodities that are very easy to decompose (Highly Perishable), therefore made efforts to extend the shelf life of fish by using preservatives. Preservatives that are not harmful to health are chitosan nanoparticles. The aim of this research are to know the characterization of chitosan nanoparticles from milkfish scales and their effect as fresh pangas catfish preservative by using concentration variation 1%, 2%, 3%, 4%, and 5% and optimization of storage time 12, 24, 36 , 48, 60, and 72 hours. Design in this research is experimental laboratory. Characterization of chitosan nanoparticles using FT-IT and SEM-EDX. While the effect of fresh pangas catfish preservation on chitosan nanoparticles is based on water, ash, protein, and ALT parameters. The results obtained on the characterization of chitosan nanoparticles on the identification of functional groups (FT-IR) showed absorption bands of OH groups at a peak 3450,99 cm-1, the CN snow absorption band was seen at the peak 2360,44 cm-1, the amine band of NH amine at the peak of 1639,20 cm-1 and the crystalline alcohol CO uptake band was observed at a peak of 1096,33 cm-1. The characterization results of SEM-EDX chitosan nanoparticles are round but clumped and clearly visible particle size changes. The experimental results were analyzed with two-way ANOVA statistic showing a significant effect between concentration variation and length of storage time to extend the durability of fresh pangas catfish. The best results of chitosan nanoparticles on fresh pangas catfish is at 5% concentrations at 72 hours of storage time with water value 16,4%, ash value 0,04%, protein value 0,04%, and ALT value 4,0 x 105cfu/g.

Abstract

Diabetes mellitus (DM) is metabolism diseases characterized by hyperglycemia and change to the cell histophatology structure of pancreas. Red betel leaves (Piper crocatum) and fragnantpandanleaves (Pandanus amaryllifolius Roxb.) has compound metabolic secondary that efficacious as anantidiabetic. The aims of the study were seek the best extract formulations of red betel leaves (EDSM) and extract of fragnantpandan leaves (EDPW) to lowering blood glucose level, repair the damage of islet langerhans, and comparing the effectiveness with metformin. The research was drafted by post test only control group design using male mencit (Mus musculus) for 31 days. In this research used complete random design with 14 treatment groups, they are normal group, DM group, metfomin group, EDPW 100%group, EDSM 10%+ EDPW 90%group, EDSM 20% + EDPW 80%group, EDSM 30% + EDPW 70% group,EDSM 40% + EDPW 60% group,EDSM 50% + EDPW 50%group,EDSM 60% + EDPW 40% group,EDSM 70% + EDPW 30% group, EDSM 80% + EDPW 20% group, EDSM 90% + EDPW 10% group, and EDSM 100%group. Based on in vivo bioassay showed that metformin have a lot of lowering blood glucose levels (p<0,05) than formulation of EDSM and EDPW but not better in improving islet langerhans tissue damage and treatment DM group with EDSM 50% + EDPW 50% effective lowering blood glucose level comparable with metfomin (p>0,05) and better in improving islet langerhans tissue damage caused by alloxan diabetogenic compound.

This research is experimental laboratory. Concentration of chicoryin soap are 0%, 25%, 50%, 75% and 100%. Anti-bacterial effectivenesstest was performed by disc method of transparent antibacterial soap of chicory extract of ethanol (Brassica rapa subspecies, pekinensis) and measured the clear zone. The analysis was performed by Two Way ANOVA test. The results of soap quality assurance standard fulfill quality standard specified by SNI in 1994 that water content test is found in formulation 6 (F6) with 75% concentration equal to 2.109%. The best free alkali test result were found in the formulation 5 (F5) with a 25% concentration of 0.041963, 50% by 0.041966 and 100% by 0.041963. The best free fatty acid test result were found in the formulation of 2 (F2) 50% concentration with free fatty acid level of 0.07852 %. For thebest pH test the conceration of 0%, 25% and 50% with pH yielded 9 and the best foam high yield test was found at 100% concentration. Result of Two Way ANOVA test with variation of extract concentration of chicory ethanol and combination of coconut oil and castor oil obtained p-value = 0.000 <0.05 which states there is real difference. The best test results are in F6 (30.6833 mm). Two Way ANOVA test results showed that transparentsolid soaps of chicory extracts had the best antibacterial effectiveness against Staphylococcus aureus with an inhibitory zone of 30.6833 mm at 100% concentration.

Abstract

One of the most dominant workplaces where heavy metal contamination occurs is the Gas Station (SPBU). Gas station workers are at high risk of being exposed to heavy metals while working due to inhaling fuel that evaporates into the air and vehicle fumes due to the behavior of motorists who do not turn off the engine while waiting in line. Determination of the level of heavy metal contamination of Zn, Cu, Pb, Cd, Fe, and Cr was determined through hair clippings using the Atomic Absorbtion Spectrophotometry (AAS) method. The gas stations used in this study are SPBU X and Y in Sidoarjo. This study aims to determine the levels of heavy metals in hair and to determine the relationship between working period, age, smoking habits, and savety with heavy metal levels in gas station workers in Sidoarjo. The type of research used is descriptive cross sectional and analytical method through filling out questionnaires and correlative statistics with SPSS. The results obtained showed that the average levels of heavy metals Zn, Cu, Pb, Cd, Fe, and Cr at SPBU X were 0.232, respectively; 0.000; 0.003; 0.001; 0.464; and 0.024 mg/g. while the average levels of heavy metals Zn, Cu, Pb, Cd, Fe, and Cr at SPBU Y were 0.516, respectively; 0.000; 0.007; -0.001; 0.345; and 0.051 mg/g. It can be said that the levels of heavy metals Zn, Cu, Pb, Cd, Fe, and Cr did not exceed the specified threshold. The results of the statistical test of the correlation between the levels of heavy metals Zn, Cu, Pb, Cd, Fe, and Cr with years of service, age, smoking habits, and PPE of gas station workers were not significant (p>0.05).

Abstract

Lempuyang Gajah (Zingiber zerumbet (L.) Roscoe ex Sm) is a medicinal plant that has many benefits in the medicinal industry. Useful as a tonic, external medicine, anti-seizure and appetite enhancer. This study aims to determine the toxicity of the lempuyang gajah. This research uses laboratory experimental methods. The lempuyang gajah plant was obtained in the village of Terungkulon, Krian. The initial stage was the administration of lempuyang gajah extract with various doses of 4000, 5000 and 6000 mg/kg BB orally, consisting of 5 treatment groups. Parameters observed, changes in toxic symptoms, macroscopic examination and parameters of SGOT, SGPT. The results were analyzed using the One Way ANOVA test. The results of the study after giving the extract did not cause death so it was included in the non-toxic category, there were several symptoms such as weakness and seizures. The levels of SGOT, SGPT showed normal average results, statistically there was no effect (p > 0.05). Macroscopic results showed no changes or abnormalities in the liver. So that the ethanol extract of lempuyang gajah can be said to be safe for humans.
