In Vitro Callus and Plant Regeneration Rate of Tarabas Rice on Several Concentrations of 2,4-D The Agricultural Research and Development Agency and the West Java Provincial Government are developing new superior varieties with Japonica rice standards, namely the Tarabas variety. However, the equivalence of somatic embryogenesis ability of Tarabas rice with original Japonica variety has not been reported. In this study, the frequency of callus regeneration of Tarabas vs Hwayoung rice varieties was compared. Induction of callus from mature embryos with several concentrations of 2,4-D showed the same extent of callus formation in both rice varieties. Callus induced by 1 ppm of 2,4-D showed the higher rate of shoot formation. On the other hand, percentage of callus formation of Tarabas rice was not affected by the increase of 2,4-D concentrations and was able to show 100% regeneration rate at the fourth week in the regeneration medium, although the shoot growth was not as fast as those from medium with 1 ppm 2,4-D. Therefore, these results suggest that Tarabas variety has a somatic embryogenesis capacity equivalent to that of japonica rice and has the potential as research objects in the field of biotechnology. Badan Penelitian dan Pengembangan Pertanian serta Pemerintah Provinsi Jawa Barat mengembangkan varietas unggul baru dengan standar padi Japonica yaitu varietas Tarabas. Namun, kesetaraan varietas Tarabas dengan varietas Japonica asli dalam kemampuan embriogenesis somatik belum dilaporkan. Penelitian ini membandingkan respons kultur jaringan antara beras Tarabas dan padi Japonica varietas Hwayoung. Induksi kalus dari embrio matang dengan beberapa konsentrasi 2,4-D menunjukkan respons pembentukan kalus yang sama pada kedua varietas padi. Kalus yang diinduksi 1 ppm 2,4-D menunjukkan laju pembentukan tunas yang lebih tinggi. Di sisi lain, kalus Hwayoung yang diinduksi konsentrasi 2,4-D yang lebih tinggi menunjukkan penghambatan dalam pembentukan tunas. Di lain pihak, pembentukan kalus padi Tarabas tidak terpengaruh oleh peningkatan konsentrasi 2,4-D dan mampu menunjukkan 100% laju regenerasi tanaman pada minggu keempat di media regenerasi walaupun pertumbuhan tunas tidak secepat pada perlakuan 1 ppm 2,4-D. Karena itu, hasil penelitian ini menunjukkan bahwa varietas Tarabas memiliki kapasitas embriogenesis somatik yang setara dengan padi japonica dan padi Tarabas mempunyai potensi sebagai obyek penelitian di bidang bioteknologi.

Optimization of Vanillin Extraction Conditions from Lignocellulose Degradation of Sugarcane Bagasse using the Response Surface Method (RSM) Sugarcane bagasse is an agricultural waste containing lignocellulose and has the potential to be processed into high-value chemicals such as vanillin. The degradation of sugarcane bagasse lignocellulose can be carried out biologically by the white rot fungus Phanerochaete chrysosporium. This study aims to obtain optimal extraction conditions in the form of ethyl acetate solvent volume and extraction time, using the response surface method (RSM). Two optimized factors were the volume of ethyl acetate (71.72; 80; 100; 120; and 128.28 mL) and the extraction time (35.16; 60; 120; 180; 204.84 minutes). The response variables were the concentration (%) and yield of vanillin (µg g–1). The research on the optimization of the response of vanillin levels and vanillin yield was carried out at 14 days incubation with the highest average total soluble phenol (TSP) value of 0.101 mg g–1. The optimal condition of ethyl acetate volume of 109.730 mL with an extraction time of 137.302 minutes was predicted to produce vanillin levels and yields of 0.0078% and 8.9089 g g–1, respectively, with an accuracy value of 93.4%. Based on the verification results, the optimal vanillin concentration and yield were 0.0077% and 8.9805 g g–1, respectively.

Review: The Role of Nanoparticles in Inhibiting the Growth of the Plasmodium Parasite Causing Malarial Disease Malaria is a health problem in Indonesia with the most cases in eastern parts of Indonesia. This study provides an overview of the potential of nanoparticles in inhibiting malaria vectors and the growth of Plasmodium parasites that causes malaria based on the latest literature as reference materials and future research ideas. Nanoparticle can be synthesized using three methods i.e. physical, chemical and biological synthesis. The use of nanoparticles with biological method is highly recommended because they are practicable, environmentally friendly, non-toxic, and easy to reproduce compared to physico-chemically synthesized nanoparticles. Nanoparticles synthesized from several plants can inhibit the growth of Plasmodium parasites with IC50 3–78 g mL–1. This activity is classified as high to moderate in inhibiting the growth of the Plasmodium parasite that causes malaria. The mechanism of inhibition of Plasmodium growth is by increasing the pH of food vacuole due to the reaction of nanoparticles with Ferriprotoporphyrin IX. The high pH in the food vacuole will interfere with metabolic activity by inhibiting the activity of aspartate and cysteine ??protease enzymes so that the parasites will die. Malaria merupakan masalah kesehatan yang dihadapi Indonesia khususnya di beberapa wilayah timur Indonesia. Kajian ini memberikan gambaran potensi nanopartikel dalam menghambat vektor malaria maupun pertumbuhan parasit Plasmodium penyebab malaria berdasarkan literatur terbaru sebagai bahan acuan maupun ide-ide penelitian di masa mendatang. Nanopartikel dapat disintesis menggunakan tiga metode yaitu fisika, kimia dan biologi. Penggunaan nanopartikel dengan metode biologi sangat direkomendasikan karena lebih mudah diterapkan, ramah lingkungan, bersifat non-toksik, dan mudah diperbanyak dibandingkan dengan nanopartikel yang disintensis dari fisiko-kimia. Nanopartikel yang disintesis dari beberapa tanaman dapat menghambat pertumbuhan parasit Plasmodium dengan IC50 3–78 g mL–1. Aktivitas ini tergolong tinggi hingga sedang dalam menghambat pertumbuhan parasit Plasmodium penyebab malaria. Mekanisme penghambatan pertumbuhan Plasmodium dengan cara meningkatkan pH vakuola makanan akibat reaksi nanopartikel dengan feriprotoporpirin IX. Tingginya pH pada vakuola makanan akan mengganggu aktivitas metabolisme dengan cara menghambat aktivitas enzim aspartat dan sistein protease sehingga parasit akan mati.

Molecular Studies on Probiotic of Human Breast Milk in the Synthesis of Exopolysaccharide (EPS) The glucosyltransferase (gtf) gene has an important role in exopolysaccharide (EPS) synthesis in probiotic bacteria. The EPS produced is associated with the adhesion ability of bacteria to the intestinal mucosa. Therefore, the gtf gene can be used as a parameter in the selection of potential probiotic through a molecular approach. This study was conducted to determine the presence of the gtf gene in probiotic from human breast milk using PCR technique. The methods in this study include the following: reculture of probiotic isolates, DNA isolation, amplification of the 16S rRNA gene using universal primers (pA and pB), amplification of specific LAB primers (LABfw and LABrv), specific primary design for the gtf gene, and the amplification of the gtf gene. The results of 16S rRNA gene amplification using universal primers obtained the amplicons of 500-1,000 bp in size. The results of amplification using specific LAB primers obtained an amplicon of about 700 bp in all isolates. The results of amplification of the gtf gene using a specific primer produced an amplicon of 325 bp in all isolates. Based on this study, it was concluded that 16 probiotic isolates from human breast milk were proven to have the gtf gene. Gen glukosiltransferase (gtf) memiliki peran penting dalam sintesis eksopolisakarida (EPS) pada bakteri probiotik. EPS yang diproduksi berhubungan dengan kemampuan adhesi bakteri pada mukosa usus. Oleh karena itu, gen gtf dapat dijadikan sebagai salah satu parameter dalam seleksi probiotik potensial melalui pendekatan molekuler. Penelitian ini dilakukan untuk mengetahui adanya gen gtf pada probiotik asal air susu ibu (ASI) menggunakan teknik PCR. Metode pada penelitian ini meliputi: reculture isolat probiotik, isolasi DNA, amplifikasi gen 16S rRNA menggunakan primer universal (pA dan pB), amplifikasi primer spesifik BAL (LABfw dan LABrv), desain primer spesifik untuk gen gtf dan amplifikasi gen gtf. Hasil amplifikasi gen 16S rRNA menggunakan primer universal diperoleh amplikon berukuran antara 500-1.000 bp. Adapun hasil amplifikasi menggunakan primer spesifik BAL diperoleh amplikon berukuran sekitar 700 bp pada seluruh isolat. Hasil amplifikasi gen gtf menggunakan primer spesifik menghasilkan amplikon berukuran sekitar 325 bp pada seluruh isolat. Berdasarkan penelitian ini dapat disimpulkan bahwa 16 isolat probiotik asal ASI terbukti memiliki gen gtf.

Analyses of DNA Damage in the Patient’s Lymphocyte Cells Post-Radiotherapy Radiotherapy given in high doses to kill cancer cells can also induce DNA damage in surrounding normal cells. The radiation dose is divided into smaller doses called fractionation to decrease the effect of radiation on normal tissue. For this reason, it is necessary to monitor the peripheral blood lymphocytes to evaluate the patient's DNA damage. The alkaline comet test is a simple and sensitive technique for detecting DNA instability. This study involved 11 patients who underwent radiotherapy up to 20 Gy, and 11 healthy subjects as controls. This study aims to see how much DNA damage is caused by a 20 Gy fractionated radiation dose in patients with various cancers. The results showed that the mean frequency of damaged cells in patients was 80.54 ± 12.52% with a mean comet tail length of 49.98 ± 12.93 µm. There was a significant difference in both the frequency of damaged cells and the mean value of the comet tail length against the control group (p < 0.001). It was concluded that high doses of radiation can cause DNA damage to peripheral blood lymphocytes. Radioterapi yang diberikan dalam dosis tinggi untuk mematikan sel kanker juga dapat menginduksi kerusakan DNA pada sel normal di sekitarnya. Dosis radiasi dibagi menjadi dosis yang lebih kecil yang disebut fraksinasi untuk menurunkan efek radiasi pada jaringan normal. Untuk itu perlu pemantauan pada limfosit darah tepi untuk mengevaluasi kerusakan DNA pasien. Uji komet alkali merupakan teknik yang sederhana dan sensitif untuk mendeteksi ketidakstabilan DNA. Penelitian ini melibatkan 11 pasien yang menjalani radioterapi hingga 20 Gy, dan 11 subyek sehat sebagai kontrol. Penelitian ini bertujuan untuk melihat seberapa besar kerusakan DNA akibat dosis radiasi fraksinasi 20 Gy pada pasien dengan variasi kanker. Hasil penelitian menunjukkan bahwa rerata frekuensi sel yang rusak pada pasien 80,54 ± 12,52% dengan rerata panjang ekor komet 49,98 ± 12,93 µm terdapat perbedaan nyata baik pada frekuensi sel yang rusak maupun nilai rerata panjang ekor komet terhadap kelompok kontrol (p < 0,001). Penelitian ini menyimpulkan bahwa radiasi dosis tinggi dapat menyebabkan kerusakan DNA sel limfosit darah tepi.

Review of Virus Inactivation Technologies for Covid-19 Pandemic Control SARS-CoV-2 virus inactivation is one of global concerns in alleviating the spread of Covid-19. The applications of virus inactivation technologies are mainly based on the knowledge of virus characteristics, its persistence on material surfaces, and environmental factors impairing its structure. Current virus inactivation methods are mostly employing chemicals dan physical treatments such as hydrogen peroxide, hypochlorite solutions, and UV light. In this paper, we discuss three current virus inactivation technologies for reducing the spread of Covid-19, i.e., room disinfection, surface disinfection, and personal protective equipment (PPE) decontamination technology. Room disinfection technology, particularly room with poor ventilation or closed air circulation, employs the combination of UV light treatment with filters. Surface disinfection technologies utilize the spraying or fogging of disinfectant solutions, and PPE decontamination technologies utilize UV light or chemical treatments to inactivate the virus. Further development and application of these technologies will help the national effort in controlling the spread of Covid-19. Inaktivasi virus SARS-CoV-2 merupakan salah satu upaya global untuk mengurangi penyebaran Covid-19. Aplikasi teknologi inaktivasi virus ini banyak bersandar pada pengetahuan mengenai karakteristik dan daya tahan virus ini pada permukaan benda dan hal-hal yang merusak struktur virus tersebut. Metode inaktivasi virus yang banyak digunakan adalah perlakuan dengan bahan kimia dan perlakuan secara fisik yaitu dengan menggunakan larutan disinfektan hidrogen peroksida, larutan hipoklorit dan sinar UV. Dalam tulisan ini, peluang aplikasi teknologi inaktivasi virus SARS-CoV-2 yang dibahas adalah teknologi disinfeksi ruangan, disinfeksi permukaan benda dan dekontaminasi alat pelindung diri. Teknologi disinfeksi ruangan khususnya pada ruangan tertutup dengan ventilasi yang kurang baik atau resirkulasi udara tertutup adalah dengan menggunakan kombinasi perlakuan sinar UV dengan filter. Teknologi disinfeksi permukaan benda menggunakan teknik penyemprotan atau pengkabutan larutan disinfektan, sedangkan teknologi dekontaminasi alat pelindung diri dilakukan dengan perlakuan sinar UV atau dengan bahan kimia. Pengembangan dan aplikasi lanjut dari teknologi inaktivasi virus ini akan membantu upaya nasional dalam penanggulangan penyebaran Covid-19.
