Abstract

Metro River is one of rivers in Malang city, located at Merjosari sub-District. The River is used as irrigation by citizen in surroundings. The aim of this research is to know the quality of water in Metro River based on the physical parameter, Chemical parameter and biological parameter. To know correlation between the physical and the Chemical parameter of the water quality test. The research method is Survey-Descriptive Quantitativ., water quality test Metro River used physical, chemical, and biological parameter relate to the Government rules Number 82 year 2001, about The Management of Water Quality and Control of Water Pollution, and the analyzed data by Microsoft Excel with calculation of correlation. The result of the research showed that the waters quality at three stations showed that the pollution levels based on the result of DO is heavily polluted to all station because the result of DO under the water standard that was set by government. While if reviewed from biological parameter that is the total of coliform bacteria sample in the Metro River is lightly contaminated. Because, the total number of coliform under standard which was set by government. The correlation analysis showed that there is real relationship between several parameters those are CO2 and pH. Base of the parameters test result is presumable the water contain organic matter. Keywords: Physical, Chemical, Biological parameter, Quality of water in Metro River, Merjosari District ABSTRAK Sungai Metro merupakan salah satu sungai yang ada di kota Malang, tepatnya di Kelurahan Merjosari. Sungai ini dimanfaatkan oleh warga sekitar sebagai irigasi. Tujuan dari penelitian ini untuk mengetahui kualitas air sungai Metro berdasarkan parameter fisika, parameter kimia, parameter biologi. Mengetahui korelasi antara parameter kimia dan fisika pada uji kualitas air sungai Metro. Metode penelitian yang digunakan adalah Survei-Deskriptif Kuantitatif. Uji kualitas air sungai sungai Metro menggunakan parameter fisika, kimia, dan biologi yang mengacu pada Peraturan Pemerintah Nomor 82 Tahun 2001 Tentang Pengelolaan Kualitas Air dan Pengendalian Pencemaran Air. Analisis data menggunakan Mikrosoft Exel dengan perhitungan Korelasi. Hasil penelitian menunjukkan bahwa kualitas perairan yang diteliti pada tiga stasiun menunjukkan tingkat pencemaran berdasarkan nilai DO, yaitu tercemar berat pada semua stasiun karena nilai DO berada dibawah standar mutu air yang telah ditetapkan oleh pemerintah. Sedangkan jika di tinjau dari parameter biologi yaitu total bakteri coliform sample air sungai metro tercemar ringan. Karena jumlah total coliform masih berada di bawah standar yang telah ditetapkan oleh pemerintah. Analisis korelasi menunjukkan ada hubungan nyata antara parameter CO2 dan pH. Berdasarkan hasil uji parameter tersebut diduga air mengandung materi organik. Kata kunci: Parameter Fisika, Prameter kimia, Parameter Biologi, Kualitas air, sungai Metro Kelurahan Merjosari.

Abstract

Abstract: Coffea chanephora contains secondary metabolites, such as alkaloids, flavonoids, terpenoids, saponins, tannins, and chlorogenic acid an ester group consisting by quinic acid, which functions to protect plants from attack by microorganisms or antibacterial compounds. Significant decrease in antioxidant properties after the drying process caused by the high temperature during the drying process so as to reduce the antioxidant activity of the sample. In accordance with research on the antioxidant resistance test of red kana flower, it was stated that the higher the temperature, the lower the antioxidant activity. The purpose of this study was to determine the growth inhibition of Escherichia coli. This study used an experimental method with “the post-test only control group design” in observing the effectiveness and optimal concentration in inhibiting the growth of Escherichia coli at 45oC. Coffee bean extract added with coffee leaf extract (Coffea chanophera) as an antibacterial on E.coli bacteria had an effect on inhibiting the growth of E.coli with concentrations of 25%, 50%, 75%, and 100% of coffee leaf extract (Coffea chanophera). added with 100% coffee bean extract (Coffea chanophera), all treatments were similar to the positive control but the diameter was smaller and significantly different up to a concentration of 100%.

Abstract

The purpose of this study was to study the effect of environmental sanitation in cowshed by farmers in the working area of KAN Jabung on the total bacteria in dairy cows' milk. This research method uses a descriptive method with repeated observations during the period of the sanitation process. Sanitation of the cage environment is carried out, namely the process of washing the cage using clean water. In observing the sanitation of the cage using an assessment sheet, it includes three components of requirements, namely: the location of the cage, the direction of the cage and the technical construction of the cage with supporting data, such as frequent illness of livestock. Testing for total bacteria in dairy cow's milk uses the TPC (Total Plate Count) test with data on average quality grades in morning milking milk. To find out the difference in the effect of sanitation from the three regions, the One-way Anova test was used. Meanwhile, to test the comparison of the average difference of the three regions using Duncan's test. The results showed that there was a significant effect in three areas of the cage between environmental sanitation in the cowshed on the total bacteria in the milk of dairy cows. The total mean bacteria from milked milk is ± 5.7 x 105 CFU/ml and meets the first grade of SNI. The type of water used for cage sanitation is thought to affect the total microorganisms in milk.
