Kualitas air secara biologis ditentukan oleh banyak parameter, antara lain parameter mikroba pencemar/ patogen. Bakteri Escherichia coli merupakan salah satu bakteri yang menjadi salah satu parameter kualitas suatu air. Jumlah kasus diare di Kota Magelang tahun 2014 mengalami kenaikan dibanding kasus diare tahun 2013, yaitu sebanyak 3.577 kasus dengan persentase sebesar 139,59% yang disebabkan oleh bakteri. Penelitian ini dilakukan untuk mengetahui ada tidaknya cemaran bakteri Escherichia coli dan mengetahui nilai Angka Lempeng Total (ALT) cemaran bakteri Escherichia coli pada air bilasan pada Rumah Potong Ayam (RPA) yang dapat berpotensi sebagai pencemar di lingkungan Kota Magelang. Metode yang digunakan dalam penelitian ini adalah cawar sebar dengan menggunakan media untuk pengujian adalah media TBX agar. Hasil penelitian menunjukkan adanya cemaran bakteri Escherichia coli yang melebihi 1x101CFU/ml pada air bilasan ayam pada beberapa RPA di Kota Magelang, yaitu 61,1% sampel uji atau sekitar 11 tempat sampling dari total sebanyak 18 tempat pemotongan ayam. Hasil tersebut menunjukkan bahwa air hasil bilasan tersebut dapat berpotensi sebagai salah satu sumber cemaran bakteri Escherichia coli pada daging ayam dan air tanah lingkungan sekitar pembuangan limbah air bilasan. Hanya terdapat 38,9% dari 18 RPA masih memenuhi ambang batas cemaran bakteri Escherichia coli. Oleh karena itu, perlu adanya langkah-langkah strategis berikutnya, yaitu pengolahan air limbah RPA dengan proses biofilter, serta dapat disosialisasikan terkait cara mengolah daging yang benar.

Jamu for rheumatism and "pegal linu" are two of the most commonly used traditional medicine products in the community, so it is a type of traditional medicine preparation that is prone to the addition of medicinal chemicals. Any type of medicinal chemical should not be added to herbal preparations. The purpose of this study was to determine is there any medicinal chemicals in traditional medicine samples for "pegal linu" and rheumatism in the Magelang area. The total number of samples used is nine. Thin layer chromatography was used to analyze medicinal chemicals in traditional medicine, and preliminary organoleptic test was performed. The next step is a quantitative analysis using the UV-Visible spectrophotometric method. Prednisone, mefenamic acid, and ibuprofen were used as standards. The stationary phase was silica gel 60 F254, and the mobile phase was ethyl acetate: chloroform (4:1) for the prednisone standard, chloroform:methanol (9:1) for the mefenamic acid standard, and chloroform:ethanol (8:1) for the ibuprofen standard. Thin layer chromatography analysis showed that three of the nine traditional medicine samples tested positive for prednisone, but none contained mefenamic acid or ibuprofen. Herbs A, D, and E contained prednisone in their samples. Prednisone concentrations in the three samples were 0,252%; 0.754%, and 2,005%, respectively.

Free radicals damage cellular structures and accelerate the degradation of important elements in the skin, thereby accelerating premature aging. Antioxidants in skin care products can shield cells from harm brought on by oxidative stress. Pegagan leaves (Centella asiatica (L.) Urban) are a natural source of antioxidants. Pegagan leaf ethanolic extract has antioxidant properties and can perhaps be applied in cosmetic products like peel-off mask gel. The objective of this research is to measure the antioxidant behavior of a mask that peels off gel composed of ethanolic extract of Pegagan leaves (Centella asiatica (L.) Urban). This research applies a one-shot case study laboratory experimental method. Pegagan ethanolic extract was utilized in concentrations of F1 (0.5% ) F2 (1%) and F3 (1.5%). The level of antioxidant activity was measured. for three formulae using the DPPH (2,2-diphenyl-1-picrylhydrazyl) technique. Organoleptic, pH measurement, viscosity, homogeneity, spreadability, and drying time are all considered in the physical evaluation of the preparation. Based on evaluation outcomes of the preparations, three formulas met the test requirements with organoleptic test parameters, a drying time of 15-30 minutes, and a pH value between 4.5 and 6.5. For the spreadability test, only F2 meets the test requirements with 5-7 cm, while F1 and F3 do not follow the criteria because the A preparation's spreadability is influenced by viscosity. The thicker the mask gel preparation, the smaller the resulting spreading area. The result examination for antioxidant activity on the ethanolic extract Pegagan leaf showed an IC50 value for F1 of 28.68 ppm, F2 of 38.51 ppm, and F3 of 48.68 ppm. Study shows making the peel-off mask prepared gel Pegagan ethanol extract meets the criteria for a strong antioxidant. The results of this research indicate the quantity of antioxidant function in addition to the outcomes of the physical assessment have an impact on the concentration of pegagan leaf extract in the gel mask that peels off.

Lung cancer is characterized by the uncontrolled growth of cells in the lung tissue, particularly in the lining of the respiratory tract. The disease has a high and alarming mortality rate, requiring prompt and appropriate management. This study aims to examine the costs and one-year survival rates of lung cancer patients at Dharmais Cancer Hospital. Data analysis was conducted in four stages: a retrospective observational study using secondary data from medical records, which described patient characteristics and factors affecting survival and treatment costs; analysis of survival curves by cancer stage and intervention; and testing differences in survival curves using the log-rank test. The results show that higher survival rates are often inversely proportional to shorter survival times, and vice versa. Stage 1 patients exhibited the most extended survival despite low survival rates for inpatients (48 months, 25%) and outpatients (53 months, 15%). Intervention types 4.00 (chemotherapy and radiotherapy) and 7.00 (chemotherapy, radiotherapy, and surgery) effectively extended survival, although associated survival rates remained low. The highest inpatient treatment costs were observed in stage 2 patients, while the highest annual outpatient costs were linked to surgical interventions, highlighting the difference between per-episode and cumulative annual expenditures.
