Review ArticleOpen accessIn the author namesBiopesticides as Promising Alternatives to Chemical Pesticides: A Review of Their Current and Future StatusLukmanul Hakim Samada, Usman Sumo Friend TambunanBiopesticides are living organisms or natural products that control agricultural pests including bacteria, fungi, weeds, viruses and insects. Biopesticides can be classified into different categories, such as microbial pesticides, plant-incorporated protectants and biochemicals. Biopesticides are a crucial component of integrated pest management programs for pest control, which lead to more natural alternatives to chemical pesticides that are eco-friendly and safer. … …OnLine Journal of Biological Sciences, Vol. 20, Issue 2 · 29 Apr 2020 · 23,614 accessesView PDFCite
Review ArticleOpen accessIn the author namesStrategies of Tuberculosis–HIV Vaccines Design using Immunoinformatic ApproachAni Fatonah, Ig. Satrio Wicaksono, Usman Sumo Friend TambunanTuberculosis is amongst the highest cause death worldwide. According to WHO, an estimated of more than a million people fell ill with Tuberculosis (TB) in 2016. The resistances of the M. tuberculosis (MTb) bacteria make drugs, not that useful in battle with TB. Vaccination is a better choice to avoid the worst cases of TB. The resistance possessed by MTb … …OnLine Journal of Biological Sciences, Vol. 19, Issue 2 · 10 May 2019 · 7,925 accessesView PDFCite
Research ArticleOpen accessIn the author namesEffect of GA3 and Shading on the Growth and Content of Artemisinin Compound in Leaf of Artemisia (Artemisia annua L.) Grown on the Medium Land of Karanganyar, IndonesiaYuni Kusumodewi, Usman Siswanto, Samanhudi, Ahmad YunusMalaria is still becomes a concern for the government of Indonesia, since this disease has affected many people. Artemisia annua L. is an aromatic plant that destroys malarial parasites, lowers fever and of which the secondary metabolite is artemisinin. Enhanced production of the artemisinin content in the whole plant is desirable. This experiment was conducted in Karanganyar, Indonesia 900m asl. … …American Journal of Applied Sciences, Vol. 14, Issue 10 · 1 Nov 2017 · 8,007 accessesView PDFCite
Research ArticleOpen accessIn the author namesModeling of Rainfall Characteristics for Monitoring of the Extreme Rainfall Event in Makassar CityWahidah Sanusi, Usman Mulbar, Hendra Jaya et al.Flooding is a common problem that occurs in some regions of Indonesia, including Makassar city. In the planning of flood control, rainfall variables are very necessary as the frequency, intensity and duration of rainfall. The relationship of these variables can be expressed in a curve Intensity-Duration-Frequency (IDF). The objectives of this study are to identify the best fitting distribution of … …American Journal of Applied Sciences, Vol. 14, Issue 4 · 10 Apr 2017 · 7,797 accessesView PDFCite
Research ArticleOpen accessIn the author namesGIS-Based Optimal Site Selection for Installation of Large-Scale Smart Grid-Connected Photovoltaic (PV) Power Plants in Selangor, MalaysiaSabo Mahmoud Lurwan, Mohammed Oludare Idrees, Goma Bedawi Ahmed et al.This study presents a GIS-based model to identify optimal sites to install large-scale smart grid-connected Photovoltaic (PV) power plants. Input datasets include digital elevation model, road networks, grid lines and daily average solar radiation. Using multi-criteria decision-making approach, we set constraining conditions for slope, proximity to the road, proximity to grid lines, solar radiation and land use to optimize the … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 30 Jan 2017 · 8,783 accessesView PDFCite
Research ArticleOpen accessIn the author namesDesigning of Disulfide Cyclic Peptide for Inhibiting Polymerase A and B1 (PAC-PB1N) in H1N1 Virus using Molecular Simulation ApproachUsman Sumo Friend Tambunan, Mochammad Arfin Fardiansyah Nasution, Arli Aditya Parikesit et al.The drug resistance A/H1N1 flu virus is emerging rapidly. Therefore, looking for potential therapy is very important. PB2, PB and PA are subunits of viral RNA-dependent RNA polymerase (RdRp). They play an important role in viral replication. The PA and PB1 binding sites can be considered as potential targets for the development of new influenza drugs. The peptide inhibitors can … …OnLine Journal of Biological Sciences, Vol. 16, Issue 3 · 24 Aug 2016 · 7,310 accessesView PDFCite
