Abstract

ABSTRACTHepatitis C virus (HCV) is the major causative agent of chronic liver disease. Recently, the inhibition of NS3 RNA helicase/ATPase activity is being explored as the specifically targeted antiviral therapy (STAT) against HCV infection. This study was aimed to elucidate potential candidates for anti-HCV therapy derived from Indonesian indigenous microalgae. The microalga designated as BTM 11 was isolated and cultured. Methanol extract of BTM 11 was screened as the opponent of purified HCV NS3 RNA helicase enzyme through colorimetric ATPase assay. Screening of chemical compound and fractionation by using gel filtration chromatography with eluent of methanol : chloroform (1:99) were conducted for identification and isolation of the bioactive compounds. The third fraction of fractionated sample showed a relatively strong ATPase inhibitory effect (81.23 ± 2.25 %) compared to the negative control. Further analysis of third fraction using thin layer chromatography (TLC) with eluent of chloroform : methanol (9:2) gave two spots with the Rf value of 0.8 and 0.37, respectively. In addition, high performance liquid chromatography (HPLC) analysis showed absorption peak with the highest abundance at the retention time of 12.483 and 16.617 minutes which absorbed at 266 and 230 nm wavelenght, respectively. According to those analyses, this study suggests that bioactive compounds derived from BTM 11 were classified as the groups of flavonoids and feasible as potential candidates for anti-HCV therapy through the inhibitory effect of NS3 RNA helicase/ATPase activity. Keywords: Hepatitis C Virus, NS3 RNA helicase, ATPase, Microalga, Flavonoids

Abstract

Reduktan herbisida dapat menjadi upaya untuk mengurangi penggunaan dosis herbisida tanpa mempengaruhi keefektifannya. Penelitian ini bertujuan untuk mengetahui keefektifan dari penggunaan reduktan herbisida dalam mengendalikan gulma serta pengaruhnya terhadap tanaman padi varietas Inpari 32. Penelitian ini menggunakan Rancangan Acak Kelompok dua faktor dengan tiga ulangan. Faktor pertama yaitu jenis bahan aktif herbisida (M) dan faktor kedua yaitu dosis reduktan herbisida (N). Hasil penelitian menunjukkan bahwa perlakuan dengan reduktan herbisida efektif mampu menekan pertumbuhan gulma golongan daun lebar dan teki. Semua petak perlakuan menujukkan potensi newgrowth (pertumbuhan gulma baru) serta regrowth (pertumbuhan gulma kembali) pada semua golongan gulma. Bahan aktif M2 (Etoksisulfuron 20 g/l dan fenoksaprop – p – etil 69 g/l) menunjukkan gejala fitotoksisitas dengan skor 1,11 pada waktu pengamatan satu minggu setelah aplikasi. Semua herbisida perlakuan menunjukkan pengaruh berbeda tidak nyata terhadap parameter pengamatan tanaman padi (tinggi tanaman, jumlah anakan total, laju pertumbuhan tanaman, jumlah anakan produktif, bobot Gabah Kering Panen serta berat 1000 butir padi). Penggunaan reduktan menunjukkan tingkat efisiensi 18 - 51% dari segi biaya dibandingkan perlakuan tanpa reduktan.

Abstract

Biofortified rice has emerged as one of the most promising strategies to enhance the micronutrient content of staple crops, offering a practical pathway to reduce stunting and improve nutritional security. In response to the challenges posed by climate change, water scarcity, and the need for more efficient production systems, this study examined the effects of water- and crop- management technologies on the physiological performance and yield of biofortified rice. A factorial randomized complete block design compared continuous flooding and alternate wetting and drying (AWD) irrigation with two crop management systems: conventional and a new technology. The AWD system enhanced photosynthesis without significantly affecting transpiration or stomatal conductance, indicating improved carbon assimilation and more efficient water use. Both AWD and the new technology individually increased dry grain yield per clump, while their combination produced heavier grains, higher productivity, greater 1000-grain weight, and improved water-use efficiency compared with other treatments. Although yield differences were not statistically significant, the consistent upward trends indicate synergistic potential when nutrient management is optimized. Overall, integrating AWD irrigation with new technology crop management can enhance resource efficiency in biofortified rice cultivation while maintaining yield stability under water- limited conditions.
