Antioksidan merupakan senyawa kimia yang dapat menyumbangkan satu atau lebih electron(electrondonor) kepada radikal bebas untuk menghambat reaksi oksidatif. Salah satu contoh yang berpotensi sebagai antioksidan adalah yoghurt. Yoghurt merupakan pangan yang mengandung sejumlah bakteri hidup yang member efek yang menguntungkan bagi kesehatan karena memiliki aktivitas antioksidan, antimikroba, antidiare serta dapat meningkatkan system kekebalan tubuh. Ada beberapa factor yang dapat mempengaruhi aktivitas antioksidan yoghurt diantaranya suhu, kondisi penyimpanan, dan bahan tambahan yang digunakan seperti penambahan cita rasa buah-buahan. Tujuan penelitian ini adalah untuk mengetahui aktivitas antioksidan probiotik dari minuman yoghurt dengan berbagai merk. Sampel diambil dari Pasar Swalayan yang terdapat di Kota Medan dengan 3 merk yang berbeda yang diberikode A, B, dan C. Aktivitas antioksidannya ditentukan dengan metode DPPH (1,1-diphenyl-2-picryhidrazyl) menggunakan spektrofotometervisible yang diukur pada panjang gelombang 516 nm. Hasil penelitian menunjukkan bahwa ada dua sampel minuman yoghurt yang diberi kode A dan B termasuk dalam kategori kuat dan sampel kode C termasuk dalam kategori lemah. Minuman Yoghurt dengan merek kode A memiliki aktivitas antioksidan yang paling kuat dibandingkan dengan minuman yoghurt merek lain (B dan C) dengan nilai IC50 dari sampel kode A(80,52ml), B(90,14ml), dan C(194,81ml).

Whitening cream is a mixture of chemicals and or other ingredients with properties that can fade dark spots on the skin. Whitening cream must be safe and must not contain harmful ingredients such as heavy metal mercury because its toxicity to the organs of the kidneys, nerves, and brain is very strong, so its use is prohibited in cosmetic preparations. The purpose of this study was to determine the levels of metallic mercury (Hg) contained in the preparation of facial whitening creams circulating in Sei Sikambing Market, Medan. The sample used in this study was a facial whitening cream that was not registered with BPOM. The method used to determine mercury levels is qualitatively using color reagents and quantitatively using AAS (Atomic Absorption Spectrophotometry). The results obtained were from 2 samples of facial whitening cream that were used positively for heavy metal mercury (Hg) characterized by the formation of a red-orange precipitate with KI reagent, yellow precipitate by NaOH reagent, white precipitate by HCl reagent. The results of the analysis showed that the highest Hg metal content in the sample with code E was 5.0241 ± 0.4064 g/g. The conclusion of this study is that two samples were positive for mercury, where the use of mercury has been prohibited by BPOM.

Traditional medicine is an ingredient or ingredient in the form of plant material, animal material, mineral material, preparation of extracts (galenic), or a mixture of these materials which have been used for generations. Jamu is traditional medicine, in general, herbal medicine cannot cure all kinds of diseases and its natural effect is not as fast as chemical drugs. Lately, medicinal chemicals are often added which are prohibited under the provisions of BPOM (Food and Drug Supervisory Agency). Antalgin is an analgesic-antipyretic and anti-inflammatory drug. Identification of antalgin in herbal aches and pains by thin layer chromatography aims to determine whether the herbal aches and pains circulating around Jalan Captain Muslim, Medan city contain levorphanoll drug chemicals or not. Antalgin identification in herbal pain relief was applied using Thin Layer Chromatography method with 60 F Silica gel stationary phase and chloroform-acetone-toluene (65: 25:10) mobile phase. From the results of identification by thin-layer chromatography (TLC) on herbal pain relief, it was found that the Rf value of the chromatogram spot on the levorphanol 0.16 reference standard was close to the sample Rf value (E) of 0.12. Based on the examination that has been carried out, it can be concluded that the positive herbal pain relief contains levorphanol drug chemicals so that the sample (E) tested does not meet the requirements.

Nata de Soya merupakan salah satu jenis pangan yang diperoleh dari pengolahan limbah cair tahu yang berbahan dasar kedelai. Penelitian ini bertujuan untuk memanfaatkan limbah cair tahu yang sering terabaikan dan menjadi penyebab rusaknya lingkungan perairan dekat perindustrian pembuatan tahu. Nata de Soya dibentuk oleh bakteri Acetobacter xylinum yang merupakan bakteria erob. Masing-masing perlakuan difermentasi selama 8-14 hari, parameter yang diamati yaitu berat nata, kadar air, kadar serat dan selulosa Nata de Soya selama 8-14 hari. Pada penelitian ini didapat data ketebalan Nata de Soya dengan perlakuan 1, 2, dan 3 dengan kosentrasi 5, 10, dan 20% starter bakteri yaitu, 2,4503 gr, 2,8922 gr, dan 2,9226. Pada berat nata didapat 0,21 cm, 0,82 cm, dan 1,53 cm. Kandungan kadar air pada Nata de Soya pada perlakuan 1,2 dan 3 dengan kosentrasi masing-masing 5, 10, dan 20% yaitu 82,71, 83,71%, dan 84,17%%. Kandungan kadar serat Nata de Soya pada perlakuan 1, 2, dan 3 dengan kosentrasa bakteri 5, 10 dan 20% didapat 49,90%, 50,74% dan 54,02%. Pada uji kadar selulosa menggunakan FTIR dengan sampel 0,4 g nilai tertinggi didapat sebanyak 3361,12 menunjukan adanya gugus aldehid dari selulosa acetat. Pemanfaatan limbah cair tahu menjadi Nata de Soya menggunakan bakteri acetobacter xylinum dapat menjadi alternative pengolahan limbah cair tahu.

Milk is a drink that is mandatory for consumption by the public, especially for children, therefore, milk must be free from contamination with Escherichia coli, Shigella sp and Salmonella sp bacteria, through the tools used are not clean, the environment is dirty, the hands of workers, and others. This study aims to determine the presence or absence of Escherichia coli, Shigella sp, and Salmonella sp bacteria in Dairy Cow Milk obtained from the Asam Kumbang Farm, Medan Selayang District. The research sample was ten samples of milk from dairy cows in one farm with different cows which were treated with two aseptic and non-aseptic treatments. The research method used is descriptive research with MPN (Most Probable Number) method to count coliform bacteria followed by an examination of LB, BGLB, EMBA media, gram staining, biochemical tests, IMVIC tests, and user testing methods on samples of Shigella sp and Salmonella bacteria sp followed by an examination of NB, SCB, SSA media, gram staining, biochemical tests, and IMVIC. The results showed that one aseptic sample A and 3 non-aseptic samples A, B, C had Escherichia coli bacteria in dairy cows' milk. The quality of milk must comply with the requirements of SNI 3141.1:2011 Fresh Milk Quality and the Maximum Limit of Microbial Contamination in SNI 7388-2009 Fresh Milk.

Antioxidants are chemical compounds that can donate one or more electrons (electron donors) to free radicals to inhibit oxidative reactions. One example that has the potential as an antioxidant is yogurt. Yogurt is a food that contains a number of live bacteria that have a beneficial effect on health because it has antioxidant, antimicrobial, antidiarrheal activity and can boost the immune system. There are several factors that can affect the antioxidant activity of yogurt including temperature, storage conditions, and additional ingredients used such as adding fruit flavors. The purpose of this study was to determine the antioxidant activity of probiotics from yogurt drinks with various brands. Samples were taken from supermarkets in Medan City with 3 different brands coded A, B, and C. The antioxidant activity was determined by the DPPH (1,1-diphenyl-2-picrylhydrazyl) method using a visible spectrophotometer measured at wavelengths. 516 nm. The results showed that there were two samples of yogurt drink coded A and B which were included in the strong category and code C samples were included in the weak category. Yogurt drink with brand code A has the strongest antioxidant activity compared to other brand yogurt drinks (B and C) with IC50 values from samples code A (80.52 ml), B (90.14 ml), and C (194, 81 ml).
