Abstract

Salmonella enterica serotipe Typhi cukup untuk menimbulkan infeksi klinis, dibandingkan serotipe lain. Antibiotik sering digunakan sebagai antibakteri, tetapi pemakaian antibiotik yang tidak tepat dapat menyebabkan efek samping yang serius. Bonggol nanas sebagai alternatif karena aktivitas enzim yang lebih baik potensi sebagai antibakteri. Penelitian ini bertujuan untuk mengetahui pengaruh aktivitas antibakteri ekstrak kasar bonggol nanas (Ananas comosus (L.) Merr.) terhadap pertumbuhan Salmonella enterica serotipe Typhi. Penelitian ini merupakan penelitian eksperimental dengan rancangan acak lengkap (RAL) terhadap 7 perlakuan dan 4 ulangan. Diuji dengan metode difusi pada konsentrasi ekstrak kasar bonggol nanas 50%, 60%, 70%, 80%, 90%, 100% dan kontrol positif kloramfenikol 30 µg. Hasil menunjukkan ektrak kasar bonggol nanas pada penelitian ini tidak berpengaruh sebagai antibakteri terhadap pertumbuhan Salmonella enterica serotipe Typhi. Akan tetapi aktifitas tersebut masih bisa dibuktikan dengan dilakukan isolasi senyawa tertentu dan modifikasi metode yang digunakan dalam ekstrasi bonggol nanas yang dapat menghasilkan senyawa yang bersifat antibakteri pada bonggol nanas untuk mengoptimal aktivitas antibakteri.

Abstract

Terbatasnya stok serbuk gergaji kayu sengon sebagai bahan baku baglog dapat mempengaruhi kelangsungan produksi jamur kuping (Auricularia auricula). Pemanfaatan limbah pertanian sebagai bahan baku alternatif baglog jamur kuping belum banyak diungkap. Ketiga jenis limbah pertanian yang tersedia melimpah di dataran rendah, yaitu jerami padi (PJP), potongan ampas tebu (PAT) dan serbuk gergaji kayu kelapa (SKK). Peforma pertumbuhan dan hasil panen jamur kuping pada ketiga jenis limbah pertanian tersebut yang dikombinasikan dengan dedak  (0, 5, 10 dan 15%) diinvestigasi pada penelitian ini. Serbuk kayu sengon (SKS) digunakan sebagai kontrol. Hasil menunjukkan bahwa waktu tercepat miselium penuh, pembentukan pinhead dan panen pertama dicapai berturut-turut pada hari ke-17-20, 29-32, dan 39-40 inkubasi oleh baglog SKK. Pengamatan pada hasil panen menunjukkan PJP adalah substrat terbaik dibanding SKS (sebagai substrat kontrol), SKK dan PAT. Sebaliknya, peningkatan konsentrasi dedak berdampak negatif pada hasil panen baglog PJP. Performa hasil panen terbaik diperoleh pada baglog PJP dengan dedak 0 % yaitu 13,67 g (berat basah) dengan berat baglog 240 g (berat basah). Hasil ini lebih tinggi 64,11 % dari hasil panen baglog SKS dengan dedak 5-10%. Pada akhirnya, hasil studi ini merekomendasikan PJP sebagai substrat alternatif pengganti SKS.

Abstract

Legumes are cultivated plants that are widely used by the community. In central Kalimantan, especially in Palangka Raya city, the legume is planted by the community as a garden plant which is consumed daily. The condition of acidic peatlands in Central Kalimantan is a limiting factor for plant growth. This study aims to determine the effect of peat water from the Sabangau River in Central Kalimantan on the germination of legume plants. The study used 4 (four) types of plants such as Vigna radiata L, Vigna unguiculata L, Phaseolus vulgaris L, and Glycine max L using a Completely Randomized Design (CRD). The plant seeds were first soaked in peat water for 3 (three) hours, then transferred to a medium covered with cotton and watered using the same water. Observations were made from the first day to the seventh day. The results showed that 3 (three) types of plants such as Vigna radiata L, Vigna unguiculata L, and Phaseolus vulgaris L were able to grow using peat water as a medium, while soybeans could not germinate. The results show that out of these three types of plants, Vigna radiata L has a better growth rate than Vigna unguiculata L and Phaseolus vulgaris L. Statistical tests using ANOVA analysis showed no significant differences between the three types of plants that grow.

Abstract

Catfish (Clarias batrachus) is a freshwater fish that is cultivated commercially by Indonesian people. Catfish is the most widely cultivated fish by the community because it has various advantages such as fast growth rates, high adaptability to the environment such as stocking with high density per unit area of ponds and being able to live in aquatic environments that lack oxygen and has a good taste and high value. high nutrition. However, the presence of Edwardsiella tarda bacteria greatly affects the survival of catfish (Clarias gariepinus) because this bacteria attacks fish. This is a crucial problem because catfish have high economic value and are widely consumed and cultivated. One way that can be done to overcome this problem is by utilizing natural ingredients, namely garlic which is a natural plant that contains antibacterial properties. Garlic is one of the natural plants that contain active ingredients of sulfur compounds such as aliin, allicin, disulfide, trisulfide. This research method uses several articles related to the effect of soaking garlic extract (Allium Sativum) on the histology of catfish kidneys infected with Edwardsiella tarda bacteria and compares the differences between normal catfish kidneys and kidneys infected with Edwardsiella tarda bacteria and proves the content of garlic on catfish kidneys ( Clarias gariepinus) infected with bacteria (Edwardiella tarda)

Abstract

Bacterial infection is a major cause of chronic infection and death that continues to threath public health worldwide. Improper use of antibiotics can cause pathogenic bacteria to become resistant to antibiotics and have side effects, so alternative sources of antibiotics from natural ingredients are needed. One type of plant that is efficacious as an antibacterial is jarak pagar leaves (Jatropha curcas). This study aims to examine the phytochemical content qualitatively using the tube method and the antibacterial activity of the ethyl acetate fraction of jarak pagar leaves using the disc diffusion method. Extraction of jarak pagar leaves by maceration method with 96% ethanol then fractionated with ethyl acetate. Data on the diameter of the inhibition zone in the antibacterial test were analyzed using the non-parametric test, namely the Kruskal Wallis test. The analysis was continued with Mann Whitney's post hoc with a confidence level (pvalue<0.05). Based on the results of the phytochemical test obtained alkaloids, saponins, flavonoids, polyphenols and tannins. The antibacterial activity of the ethyl acetate fraction of jarak pagar leaves at a concentration of 8 mg/mL showed an inhibition zone of 19.73±0.25 mm which was included in the very moderate category and weakly inhibited at a concentration of 0.5 mg/mL which was 4.87±0.31 mm and the results of statistical tests showed that the ethyl acetate fraction of jarak pagar leaves had antibacterial activity and each concentration had a significant effect on inhibiting the growth of S. aureus.

Abstract

Various food sources and herbal plants are rich in Vitamin C, a crucial antioxidant. One such plant is Banto grass, which belongs to the Poaceae family and is commonly used as an herbal drink in many communities. It contains active compounds known for their healing and disease-prevention properties. This study aimed to evaluate the levels of vitamin C in Banto grass extract using different solvents. The research followed a descriptive approach and used UV-Vis Spectrophotometry as the analytical method. The findings showed that the vitamin C content varied significantly in Banto grass extracts prepared with distilled water, ethanol, and methanol solvents. The extract prepared with methanol had the highest vitamin C content of 4,030 ppm, which was more than the eco-enzyme water extract that contained 4,030 ppm of vitamin C. However, the extracts prepared with distilled water and ethanol solvents had lower vitamin C levels of 2,507 ppm and 3,687 ppm, respectively. This research highlights the potential of Banto grass as a rich source of vitamin C, which is essential for collagen formation, wound healing, and antioxidant activity, leading to faster wound healing and optimal tissue repair.
