Abstract

Aglaonema sp. is well known as an ornamental plant in Indonesian society. It has leaf with various beautiful patterns. Aglaonema pink katrina is one of the imported hybrids Aglaonema. A method to increase plant yield quickly is tissue culture. The crucial step in plant tissue culture is sterilization. This study aimed to find the best sterilization method by looking at the effect of concentration and immersion time of sodium hypochlorite (NaOCl) as disinfectant to reduce contaminants explant Aglaonema Pink Katrina leaves. In this study, there were 11 groups consisting of positive control, negative control, and immersion with 2,5; 5%; and 10% NaOCl for 1 minute and 3 minutes. Parameters observed included the time of first contamination, percentage of bacterial and fungal contamination, and appearance of explants for 28 days. The DMRT test showed significant differences in all treatments of disinfectant concentration and soaking time.The results show contamination first time occurred in code S0a (negative control), the highest percentage of sterile explants was in code A5, and explants that were still green/fresh were found in codes A5 and A8 after observation.

Abstract

Kultur in vitro merupakan salah satu solusi alternatif untuk mengatasi kesulitan perbanyakan anggrek melalui biji. Keberhasilan regenerasi protokorm anggrek dipengaruhi oleh penambahan ZPT dan air kelapa ke dalam medium. Oleh karena itu, penelitian ini bertujuan untuk menentukan pengaruh konsentrasi air kelapa dan BAP terhadap regenerasi protokorm Dendrobium hibrida. Penelitian menggunakan Rancangan Acak Lengkap dengan dua faktor yaitu konsentrasi air kelapa dan BAP. Paramater yang diamati meliputi persentase tunas, jumlah tunas, tinggi protokorm, dan persentase akar. Hasil menunjukkan bahwa penambahan air kelapa dan BAP ke dalam medium VW berpengaruh nyata terhadap tinggi dan persentase akar protokorm. Konsentrasi air kelapa (10%) tanpa penambahan BAP dapat meningkatkan persentase tunas, akar, jumlah tunas, dan tinggi protokorm Dendrobium hibrida. Hasil penelitian menunjukan bahwa penggunaan air kelapa secara tunggal maupun kombinasi dengan hormon sitokinin (BAP) signifikan dalam mempercepat regenerasi protokorm Dendrobium hibrida. Ini merupakan penelitian pertama yang melaporkan penggunaan air kelapa dan BAP pada regenerasi protokorm hasil persilangan Dendrobium stratiotes x Dendrobium wulaiense.

Abstract

Probiotics are a group of beneficial microorganisms that can improve the health of their host. Lactobacillus species are lactic acid bacteria that have great potential as probiotics, in which cow’s milk is a great source of lactic acid bacteria. In this study, Lactobacillus spp. were isolated from fresh local Indonesian cow’s milk. The methods used to characterize the Lactobacillus spp. were (i) biochemical tests including catalase, hemolytic and sugar fermentation tests; (ii) tolerance tests against salt (NaCl 2%, 4% and 6%), low pH (2, 3, 4, 5, 6 and 7) and temperature (7°C, 37°C and 45°C); and (iii) 16S rRNA sequencing. The isolation yielded 14 isolates matching the criteria of Lactobacillus spp. colony and cell (i.e., Gram positive rods that did not produce endospores and did not have a waxy layer covering its cell wall). Based on subsequent biochemical tests, 5 isolates were suspected as potential probiotic Lactobacillus spp. The 16S rRNA sequencing revealed that the isolate L was Limosilactobacillus fermentum. In conclusion, this study demonstrated that local cow’s milk could be used to isolate Lactobacillus spp.

Abstract

Antibiotic resistance has become a common problem in poultry farming in Indonesia. One of them is caused by improper use of antibiotics. This study aims to determine the pattern of resistance of Salmonella sp. isolated from laying hens to antibiotics. The samples used in this study were thirty samples of fresh faeces of laying hens from Kediri District, West Lombok Regency. The samples were isolated and identified through Gram staining and biochemical tests (indole, methyl red-Voges Proskauer, triple sugar iron agar, citrate, and urease), resulting in ten positive samples of Salmonella sp. The study continued with antibiotic resistance testing using disc diffusion or Kirby-Bauer methods. The antibiotics used in the study were aztreonam, ciprofloxacin, streptomycin, chloramphenicol, and tetracycline. The results showed that Salmonella sp. has been resistant to some antibiotics. The highest resistance levels are streptomycin and tetracycline at 50% (5/10), while the lowest is ciprofloxacin at 10% (1/10). Antibiotics that are still sensitive are aztreonam 90% (9/10) and chloramphenicol 100% (10/10). The findings of this study conclude that there is a pattern of antibiotic resistance in laying hens farms that can have a negative impact on human and animal health.

Abstract

Tempe merupakan produk pangan berbahan kedelai (Glycine max) yang difermentasi dengan melibatkan mikroba dari genus Rhizopus. Tempe memiliki berbagai kandungan gizi dan senyawa, salah satunya adalah antioksidan. Untuk meningkatkan kandungan antioksidan dalam tempe dapat dilakukan dengan penambahan bahan alami. Biji chia (Salvia hispanica) dipilih karena termasuk bahan pangan fungsional dan memiliki kandungan antioksidan. Tujuan penelitian ini untuk mengetahui efektivitas penambahan biji chia pada fermentasi tempe kedelai dalam peningkatan antioksidan dan nilai kesukaan. Penelitian dilakukan menggunakan RAL dengan satu faktor dan empat taraf perlakuan, yaitu konsentrasi penambahan biji chia 0%,  0,5%, 1% dan 1,5% (b/b). Penentuan aktivitas antioksidan dilakukan dengan metode DPPH, sedangkan uji hedonik dilakukan menggunakan kuesioner pada 15 orang panelis. Hasil pengukuran antioksidan menunjukkan penambahan biji chia pada tempe dapat meningkatkan aktivitas antioksidan yang dapat dilihat pada persen inhibisi. Persen inhibisi paling tinggi yaitu pada konsentrasi biji chia 1% yaitu sebesar 69,83%. Pada uji hedonik dengan uji Univariate dan uji lanjutan Duncan, perlakuan tempe tanpa pemberian bumbu menunjukkan tidak berbeda nyata antar konsentrasi perlakuan pada parameter aroma dan tekstur. Sedangkan perlakuan tempe dengan penambahan bumbu menunjukkan tidak berbeda nyata antar konsentrasi perlakuan pada parameter tekstur dan rasa.

Abstract

Adherence to intestinal mucosa is one of the crucial probiotic traits. This ability varied among strains. This study aims to evaluate the cell surface properties and adherence potential of Indonesian Indigenous LAB. The adherence potential was evaluated using auto- aggregation, coaggregation against Salmonella, cell hydrophobicity, and adherence to stainless-steel surface. All strains classified as having medium high aggregation (>90%) after 24 h of incubation and can coaggregate with Salmonella (58-92%). Among all strains, Levilactobacillus brevis AB3 showed the highest hydrophobicity (36%) and adhesion to stainless steel (6.37 log CFU/mL). Current findings suggest that Indonesian Indigenous LAB, especially L. brevis AB3, possessed an adherence property and has a potential to be developed into probiotic bacteria.

Abstract

The currently used bleaching materials in skeletal preservation are hydrogen and carbamide peroxide materials with specific concentrations and techniques that impact environmental sustainability. This research describes a simple and eco-friendly technique for preserving skeletons. This research used a qualitative approach. Data were collected through observation and documentation. The collected data were analyzed descriptively. The results show that natural extracts, such as lemon combined with baking soda and commercial bleaching cloth agent, can bleach the skull and bone to preserve the skeleton. The commercial bleaching cloth agent is more capable of bleaching animal skulls and bones to preserve skeletons than natural extracts combined with baking soda do; however, the result is more brittle skeletons. Although specimens in lemon extract combined with baking soda solution more slowly clean and bleach skeleton than commercial bleaching solution, skeletal animals have bond strength and environment-friendly processes. This study recommends that an eco-friendly bleaching agent for skeletal preservation should be applied because it can cope with biological practices about osteology and other science subjects.

Abstract

Salah satu komoditas buah utama Indonesia adalah jeruk Siam. Namun, banyak tanaman jeruk di indonesia yang terkena penyakit Citrus Vein Phloem Degeneration (CVPD). Penelitian ini bertujuan untuk mengidentifikasi secara lebih pasti keberadaan bakteri Liberobacter asiaticus penyebab penyakit CVPD pada tanaman jeruk yang menunjukkan gejala klorosis dan juga keberadaan bakteri L. asiaticus penyebab penyakit CVPD pada tanaman jeruk yang tidak menunjukkan gejala klorosis. Untuk mencapai hal tersebut, teknik PCR akan digunakan untuk analisis molekuler bakteri L. asiaticus. Dengan mengamati sampel daun dari tanaman jeruk siam Kintamani yang menunjukkan gejala klorosis dan yang tidak menunjukkan gejala klorosis, maka metodologi penelitian eksploratif diterapkan dalam penelitian ini. Pita DNA pada 1.160 bp tidak ditemukan pada sampel daun jeruk yang diuji, baik pada sampel daun jeruk yang sehat maupun pada sampel daun jeruk yang terindikasi klorosis. Tanaman jeruk yang menunjukkan gejala klorosis tidak ditemukan bakteri L. asiaticus pada sampel daunnya. Hal ini mungkin disebabkan oleh kurangnya unsur hara di dalam tanah, konsentrasi bakteri yang rendah, atau distribusi bakteri yang tidak merata di dalam jaringan daun. Kesimpulan yang didapat dari penelitian ini adalah keberadaan bakteri L. asiaticus penyebab penyakit CVPD tidak dapat terdeteksi keberadaannya pada sampel daun jeruk siam yang bergejala dan tidak bergejala klorosis.
