Abstract

Telah dilakukan penelitian tentang analisis logam timbal (Pb), besi (Fe) dan mangan (Mn) air tanah sekitar tempat pembuangan akhir (TPA) sampah Sukadiri Kabupaten Tangerang. Tujuan penelitian untuk mengetahui kandungan logam Pb, Fe dan Mn kemudian dibandingkan dengan baku mutu air bersih. Teknik pengambilan sampel menggunakan metode purposive sampling dan dianalisis secara deskriptif numerik. Tujuh sampel air tanah diambil dengan radius 400-1000 meter dari TPA. Kandungan Pb, Fedan Mn di ukur menggunakan metode Standar Nasional Indonesia (SNI) secara spektrofotometer serapan atom (SSA). Berdasarkan penelitian laboratorium diperoleh kandungan logam Fe antara 0,02-1,16 mg/L, kandungan logam Mn antara 0,23-3,55 mg/L, dan kandungan logam Pb tidak terdeteksi. Hasil penelitian menunjukkan bahwa 5 sampel melampaui baku mutu kualitas air bersih

Abstract

Study about the analysis of sugar content in popular drinks around UIN Jakarta has been carried out. The purpose of this study was to determine the sugar content of glucose and sucrose in popular drinks. This type of research is quantitative research. The method used is descriptive analysis. The number of samples taken was 10 consisting of Thai tea drinks, boba milk, sweet iced tea taken from sellers around UIN Jakarta. The results showed that the sugar content of glucose was between 5-66,5 grams, while the results of the sucrose test contained between 1-26 grams and the total sugar content of contemporary drinks was between 23-70 grams. The results showed that there were 2 samples of contemporary drinks that exceeded the recommended intake of 50 grams of sugar per day according to Minister of Health Regulation No. 30 year 2013.

Abstract

A study has been conducted on the analysis of heavy metals Pb and NO2 in ambient air at the UIN Jakarta campus. The purpose of the study was to determine the content of heavy metals Pb and NO2 in ambient air at the UIN Jakarta campus and then compared with air quality standards. Ambient air quality is an important factor in creating a healthy and sustainable campus environment. Measurements were carried out at strategic locations using methods according to the Indonesian National Standard (SNI), namely the wet ashing method for measuring Pb metals and the Griess Saltzman method for measuring NO2 in the air. Sample analysis used an atomic absorption spectrophotometer (AAS) and  UV-Visible spectrophotometer. Measurements were taken for 1 hour in the morning. Nine air sample locations were taken from the UIN Jakarta campus. Based on the analysis results, the average Pb content was <0.0058-0.048 µg/Nm3 and the NO2 concentration in the air ranged from 0.04-1.32 µg/Nm³. The study results showed that the Pb and NO2 levels in ambient air at the UIN Jakarta campus were still below established quality standards. These results provide a general overview of the relatively good air quality at the UIN Jakarta campus and the importance of strengthening the Green Campus program.
