Abstract

Daging ayam merupakan bahan makanan yang memiliki kandungan protein dan air yang tinggi, yang cepat mengalami pembusukan. Daun salam merupakan salah satu bahan alami karena dapat digunakan sebagai pengawet karena mengandung minyak atsiri, air, tanin, dan flavonoid yang dapat mencegah bakteri patogen penyebab pembusukan makanan. Ibu rumah tangga sering menggunakan daun salam untuk mengawetkan unggas, yang kerapatan ekstrak dan waktu perendamannya tidak diketahui. Parameter yang diamati adalah kombinasi warna, tekstur dan rasa ayam. Untuk perlakuan ayam digunakan ekstrak daun salam (Cygizium polyanthemum) dengan konsentrasi 0%, 20%, 40%, 60%, 80% dan 100%, dan perlakuan diulang 4 kali selama 1 jam, 2 jam, dan 3 jam. . Berdasarkan hasil penelitian dapat disimpulkan bahwa perlakuan yang paling efektif digunakan sebagai pengawet alami unggas adalah perendaman dalam konsentrat ekstrak 60% selama 2 jam

Abstract

Semangka merupakan tanaman semusim dari famili Cucurbitaceae, dan buah semangka memiliki banyak manfaat begitu juga dengan kulitnya, dan kulit semangka mengandung berbagai vitamin dan mineral yang sangat bermanfaat bagi tubuh. Penelitian ini bertujuan untuk mengetahui apakah limbah kulit buah semangka dapat digunakan sebagai bahan baku pembuatan nata berdasarkan parameter konsistensi, ketebalan, berat, warna, rendemen dan kadar air serta kadar serat. Metode yang digunakan dalam penelitian ini adalah metode deskriptif kualitatif dengan waktu pengamatan yang berbeda yaitu 10 hari, 12 hari dan 14 hari untuk melihat perubahan fisik selama proses fermentasi Nata. Sampel kulit semangka diambil secara acak dari pedagang sari buah dan buah. Hasil penelitian menunjukkan bahwa berdasarkan pengamatan 10, 12 dan 14 hari, rata-rata ketebalan ketiga nata adalah 1,7 cm, 2, 2 cm, 2,2 cm dan rata-rata berat ketiga nata adalah 756,3 g, 802,0 g, 822,3 g, tekstur lahir kenyal, warna putih keruh, aroma asam. dan rendemen lahir pada hari ke-14 adalah 82,3%, 79,5%, 82,7% dan diperoleh kadar serat 4,31% dan kadar air 97,8.

Abstract

Water  is  a  basic  need  for  humans  because  it  is  needed,  among  others,  for  households,  industry, agriculture and improving public health. Clean water that meets the standards, namely physical, chemical, and microbiological requirements. Escherichia coli is one of the microbiological indicators in water. One of the sources of clean water used by the people in the city of Medan comes from the Deli river. The development of industry and settlements around the Deli river causes water pollution. Freshwater mussel as a biofilter that can be used to maintain the water quality of the Deli river. This study aims to determine the effective use of mussel as a biofilter of Escherichia coli bacteria and the most effective length of time to improve water quality. This study used RAL (Completely Randomized Design) with treatment durations K0 (Control), K1 (Day 5), K2 (Day 10 days) and Day 15. The results showed that mussel was effectively used as a biofilter to reduce the number of Escherichia coli and for 10 days was quite effective in reducing the number of Escherichia coli in Deli river water.

Abstract

This study aims to determine the active ingredients contained in papaya leaf extract (Carica papaya) and white turmeric extract (Curcuma zedoaria) and their antimicrobial activity against Escherichia coli and Staphylococcus epidermidis. This research was conducted using experimental methods at the Laboratory of Molecular Biology, Faculty of Medicine, University of Prima Indonesia. The research data were analyzed using a completely randomized design approach. Papaya leaf extract and white turmeric were made at different concentrations of 25%, 50%, 75% and 100% and the positive control was the antibiotic chloramphenicol (2 g). The results showed that papaya leaf extract contains active compounds of flavonoids, alkaloids, terpenoids and saponins. While white turmeric extract contains flavonoids, steroids, tannins and saponins. Papaya leaf extract 100% is the best treatment to suppress the growth of bacteria Echerichia coli and Staphylococcus epidermidis with an average inhibition of 14,110 mm and 14,707 mm, respectively. The administration of 100% white turmeric extract was the best treatment to suppress the growth of E. coli and S. epidermidis with an average inhibition of 14,307 mm and 13,743 mm, respectively.

Abstract

Salmonella sp. is a pathogenic microbe that causes digestive disorders that can cause death. One way to treat diseases caused by the bacteria Salmonella sp. is the use of antibiotic therapy. Salmonella sp. susceptible to antibiotic resistance due to improper use. The purpose of this study was to determine the susceptibility of Salmonella sp. Erythromycin and Chloramphenicol antibiotics. In this study, antibiotic sensitivity was tested using the Kirby-Bauer method (diffusion test) with a concentration of Erythromycin 250 mg/mL and antibiotics 500 mg/mL, Chloramphenicol antibiotics at concentrations of 250 mg/mL and 500 mg/mL. mL with 3 repetitions. The sample used in this study was a strain of Salmonella sp. suspended using Brain Heart Infusion Broth (BHIB) media and the antibiotic test was carried out using Mueller Hinton Agar (MHA) media. The greatest inhibition was seen in treatment with Chloramphenicol 500 mg/mL with an inhibition zone of 38.6 mm, followed by Chloramphenicol 250 mg/mL with an inhibition zone of 33.3 mm. The antibiotic Erythromycin 500 mg/ml had moderate inhibition against Salmonella sp. with an inhibition zone of 17.3 mm, while the antibiotic dose of Erythromycin 250 mg/ml produced a weak inhibitory effect on Salmonella sp. with a zone of inhibition of 12.5 mm.

Abstract

Fish is a kind of easily-damaged raw food which mostly caused by microorganism i.e bacteria, mold and yeast. Fish salting is one of common applied preservation method to avoid bacterial contamination as decay prevention. Another common method is by adding borax in fish preservation process which can inhibit the growth of microorganism but it caused a negative effect for consummer’s health. The objective of this study is to examine the presence of borax in the salted fish that is marketed at the Tanjung Balai Traditional Market, North Sumatra Province. This study used a qualitative test method by testing the sample in the laboratory in accordance with the standards of the Regional Health Laboratory. The results of the qualitative test of borax on 30 samples of salted fish from the market revealed that none of samples altered the color of tumeric paper after being dipped in the sample solution. This finding indicated that all samples of salted fish contain no borax.
