Abstract

Lemon peel waste (Citrus limon (L.) Burm.F.) contains secondary metabolites that function as antibacterials, such as alkaloids, flavonoids, and triterpenoids. This study aims to determine the formulation of antiseptic solid soap and the antibacterial activity of the ethanolic extract of the lemon peel by the diffusion method. The results showed the best formula for making antiseptic solid soap with ethanolic extract of lemon peel based on the requirements of SNI 06-4085-1996 was at a concentration of F3 (15%), homogeneous, had a pH of 8.54-9.82, foam height was around 3.5-4.7 cm, and a strong inhibition zone of about 12.48 mm. The conclusion of this study is that lemon peel has antibacterial properties that can kill the growth of Staphylococcus aureus bacteria.

Abstract

Lead (Pb) is one of dangerous heavy metals that is toxic for human bodies. Lead can be found in the air in the form of air pollution which is produced by the fuel of motor vehicles. According to WHO, in 1995, the level of lead inside the human body can be divided into three levels which are, low (<10ppm), moderate (10-20 ppm), otherwise high (>20ppm) according to the category of pollution. A pedicab driver and a street vendor who frequent the street will surely very often be exposed to vehicle fumes which contains lead (Pb). This experiment is aimed to find out the level of Pb in the hair of pedicab drivers and street vendors around Kapten Muslim Street, Medan. From the overall population is randomly taken each 4 (four) hair samples from pedicab drivers and street vendors, and then continued with an examination using AAS (Atomic Absorption Spectrophotometer). From the result of the experiment, overall obtained that 1 (one) out of the rest is within the high level of toxicity (20,138 ppm), and then 2 (two) within the moderate level of toxicity (10,697 - 16,69 ppm), and 5 (five) others within the low level of toxicity (0,862≈4,533 ppm). This shows that almost all pedicab drivers and street vendors around the Kapten Muslim Street, Medan are already poisoned with heavy metal, Pb, inside their bodies.

Abstract

Textile liquid waste contains organic compounds and suspended solids such as BOD, COD, and TSS, which can cause environmental pollution. This study aims to determine the levels of BOD, COD, and TSS in textile wastewater using activated charcoal from the skin of salak before and after activation with phosphoric acid (H3PO4) at a concentration of 6%.The research results that have been carried out, on the making of activated charcoal from the skin of salak have been successfully carried out and meet the requirements of SNI 06-3730-1995, obtaining 2.4% water content, 2.3% ash content, and 476 mg/L iodine absorption. FT-IR spectrum analysis activated charcoal from the skin of salak has an O-H hydroxyl group at the peak of 3817 cm-1, C=O carbonyl group at 1713 cm-1, and C-O ether group at 1175 cm-1. FT-IR spectrum analysis activated charcoal from the skin of salak has O-H hydroxyl group at the peak of 3817 cm-1, C=O carbonyl group at 1713 cm-1, and C-O ether group at 1175 cm-1. Based on SEM analysis, activated charcoal from activated skin of salak has larger pores and surface area than before activation. Based on atomic absorption spectrophotometry analysis of textile wastewater without the addition of activated charcoal, the levels of BOD were 480 mg/L, COD 650 mg/L, and TSS 470 mg/L. After the addition of unactivated activated charcoal, the levels of BOD were 120 mg/L, COD 150 mg/L, and TSS 140 mg/L. After the addition of activated charcoal, BOD levels were 60 mg/L, COD 80 mg/L, and TSS 95 mg/L.This study concludes that activated charcoal from the skin of salak can reduce, levels of BOD, COD, and TSS in textile waste and has met the requirements set out in the Regulation of the Minister of the Environment of the Republic of Indonesia Number 5 of 2014.

Abstract

Acid fast bacteria (AFB) are cell walls containing complex lipids so that in Ziehl-Neelsen staining they can bind dyes because they are not washed off by 3% HCl Alcohol (Alcoholic Acid). One of the host factors in pulmonary tuberculosis is smoking habits and exposure. Smoking habits will damage the defense mechanism of the lungs, which causes the lungs to be more easily infected with tuberculosis germs. The purpose of this study was to determine the results of analysis of acid-fast bacteria in the sputum of active smokers. The research method used was descriptive cross-sectional by examining acid-fast bacteria in the sputum of active smokers suspected of having pulmonary tuberculosis by microscopic examination of sputum (direct smear smear) using the Ziehl-Neelsen staining method. smear examination with Ziehl-Neelsen staining in patients with tuberculosis at Putri Hijau Hospital in 2022, totaling 20 samples, found 4 positive results and 16 samples with negative results.
