PEMERIKSAAN CEMARAN Escherichia coli, Shigella sp DAN Salmonella sp PADA SUSU SAPI PERAH YANG DIPEROLEH DARI PETERNAKAN ASAM KUMBANG KECAMATAN MEDAN SELAYANG

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

IDENTIFIKASI ANTALGIN DALAM JAMU PEGAL LINU SECARA KROMATOGRAFI LAPIS TIPIS

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

UJI AKTIVITAS ANTIOKSIDAN DALAM BEBERAPA MINUMAN YOGHURT DENGAN METODE DPPH (1,1-Diphenyl-2-Picryhydrazil)

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)

SOSIALISASI KANDUNGAN YANG TERDAPAT DALAM JAMU ANTALGIN DALAM MENGATASI PEGAL LINU

Obat tradisional adalah bahan atau ramuan bahan yang berupa bahan tumbuhan, bahan hewan, bahan mineral, sediaan sarian (galenik) atau campuran dari bahan tersebut yang secara turun temurun telah digunakan. Jamu merupakan sebagai obat tradisonal, pada umumnya jamu tidak dapat menyembuhkan segala macam penyakit dan efek kerjanya almiah tidak secepat obat kimia. Akhir-akhir ini sering ditambahkan bahan kimia obat yang dilarang berdasarkan ketentuan BPOM (Badan Pengawas Obat dan Makanan). Antalgin merupakan obat analgetik-antipiretik dan antiinflamasi. Tujuan pengabdian masyarakat ini untuk memberikan penyuluhan dan informasi kandungan yang terdapat dalam jamu antalgin dalam mengatasi pegal linu. Hasil kegiatan pelaksanaan program pengabdian masyarakat kandungan yang terdapat dalam jamu antalgin dalam mengatasi pegal linu. Banyak faktor yang mendasari penggunaan jamu seperti resiko efek samping yang kecil dan biaya yang relatif murah. Melihat cukup besarnya permintaan masyarakat akan jamu, banyak produsen yang memanfaatkan kesempatan ini dengan memproduksi berbagai macam produk unggulan mereka. Kesimpulan bahwa penyuluhan terlaksana sesuai pelaksanaan dan rencana, mendapat  sambutan yang baik dari pemerintah setempat Kelurahan Tualang, Kecamatan Perbaungan, Kabupaten Serdang Bedagai, Sumatra Utara, masyarakat sekitar mendapatkan informasi serta pengetahuan dan menerapkan informasi tersebut bagi keluarga dan masyarakat lainnya

PENERAPAN METODE SPEKTROFOTOMETRI SERAPAN ATOM (SSA) DALAM MENGANALISIS LOGAM MERKURI (Hg) PADA KRIM PEMUTIH WAJAH

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

ANALISIS FAKTOR YANG MEMPENGARUHI PERTUMBUHAN KULTUR SEL CHO (Chinase Hamster Ovarium) PADA PEMBUATAN OBAT TRASTUZUMAB DI PT. BIO FARMA

This study examines what factors can affect the growth of CHO cell cultures which are often used in biological and medical research and commercially in the production of therapeutic proteins. The purpose of this study was to determine whether CHO cells were able to grow and reproduce with the process flow and manufacturing method of drug preparations in accordance with the requirements of the applicable legislation. The workings of this research are divided into two stages, namely the microbiological stage and the biotechnology stage. The microbiological stage begins with making a working culture, then purification is carried out for culture rejuvenation, harvesting, cell culture breakdown, and purification of target cells. At the biotechnology stage, protein measurements were carried out, Optical Density 600 observations, polyacrylamide gel SDS electrophoresis, and gel electrophoresis staining
