Abstract

 AbstrakSARS-CoV-2 merupakan virus yang menyebabkan Coronavirus Disease 2019 (COVID-19) di seluruh dunia dan sampai saat ini kasus terbaru masih terus dilaporkan. Diagnostic test merupakan hal yang krusial untuk dikembangkan. Prinsip diagnostic test COVID-19 berbasis antigen, yaitu mendeteksi virus SARS-CoV-2 melalui respon antibodi dari penderita. Penelitian ini bertujuan untuk memproduksi antibodi poliklonal menggunakan protein rekombinan RBD-Spike untuk mendeteksi virus SARS-CoV-2 berbasis antibodi. Penelitian dimulai dengan penentuan domain RBD-Spike menggunakan pensejajaran asam amino, dan konstruksi DNA untuk RBD-Spike pada vektor ekspresi pET28a menggunakan sintetik nukleotida. Produksi protein rekombinan RBD-Spike diekspresikan pada sel bakteri Escherichia coli. Purifikasi dilakukan untuk memperoleh protein RBD-Spike dan selanjutnya digunakan sebagai antigen untuk induksi antibodi poliklonal pada kelinci. Hasil penelitian menunjukkan bahwa ekspresi protein rekombinan RBD-Spike SARS-CoV-2 memerlukan induksi IPTG 0,1 mM dan terekspresi dalam bentuk inclusion bodies dengan ukuran 39 kDa. Purifikasi protein RBD-Spike dilakukan menggunaan resin afinitas NiNTA, elektroelusi, dan dialisis. Total protein RBD-Spike yang diperoleh sebanyak 4 mL dengan konsentrasi 10 mg/mL. Analisa Ouchterlony menunjukkan bahwa antibodi poliklonal terdeteksi pada minggu kedua setelah injeksi booster dan analisa spesifitas antibodi terhadap antigen menunjukkan bahwa antibodi poliklonal dapat mendeteksi protein RBD-Spike pada konsentrasi 0,1 µg. Selanjutnya diharapkan antibodi poliklonal dapat digunakan untuk deteksi keberadaan virus SARS-CoV-2 dan dapat dikembangkan untuk kit deteksi berbasis antibodi.AbstractSARS-CoV-2 is the virus that causes Coronavirus Disease 2019 (COVID-19) worldwide and the latest cases are still being reported until now. The diagnostic test is a crucial to be developed. The principle of the antigen-based COVID-19 diagnostic test is to detect the SARS-CoV-2 virus through antibody response from the patients. This study was conducted to produce polyclonal antibodies using recombinant protein RBD-Spike. The research was carried out by determining the RBD-Spike domain using amino acid alignment and constructing the DNA of RBD-Spike to the expression vector of pET28a using nucleotide synthesis. Production of RBD-Spike recombinant protein was expressed in Escherichia coli. Purification was carried out to obtain RBD-Spike protein and used to induce polyclonal antibody ina rabbit. The results showed that the expression of RBD-Spike recombinant protein required induction of IPTG 0.1 mM and was expressed in inclusion bodies with molecular size of 39 kDa. The purification of RBD-Spike protein was carried out using resin affinity, electroelution, and dialysis. The total protein of RBD-Spike obtained was 4 mL with a concentration of 10 mg/mL. Ouchterlony analysis revealed that polyclonal antibody was detected in the second week after booster injection and analysis of antibody specificity showed that polyclonal antibodies detected RBD-Spike protein at the concentration of 0.1µg of RBD-Spike protein. Moreover, it is expected that our polyclonal antibody detect the SARS-CoV-2 virus and can be developed for antibody-based detection kits.

Abstract

Science and technology are currently developing in all fields, such as vehicle construction, building construction, industry, and materials engineering. Especially in the field of material engineering used for the manufacture of composite materials. Currently the transition of materials from metal to composites is also in great demand in various fields including in the automotive, transportation, shipping, aerospace, health, and various other fields. In the components of a vehicle, the components that have the most potential to be reduced are the main structural components, namely the floor, body, and ribs. Efforts to reduce the weight of the material in these components are carried out to reduce the amount of fuel consumption, so the ratio of strength and density of a material is one of the important properties that needs to be considered. This study used the hand lay up method with a comparison of volume fraction variations of 15%: 85% and 20%: 80%. With the aim of adding volume fractions with optimal combinations, it is hoped that the tensile strength will get better. The highest average tensile strength is with a volume fraction ratio of 15%: 85% of 19.04 MPa. While the lowest average tensile strength is with a volume fraction ratio of 20%: 80% of 17.78 MPa. It can be concluded that with increasing fiber volume fraction, the tensile strength decreases. This happens because there are several defects in the form of holes and voids which indicate poor bonding between the fibers and the matrix.

Abstract

Sorghum is a type of cereal plant that easily adapts to stressful environmental conditions. Sorghum has many benefits as it can be used as food, feed, and energy sources, making it a promising crop for development on dry land in Indonesia. Drought impacts plants during their growth process, causing physiological and biological changes. This study aims to determine the effect of drought stress on the morphology and chlorophyll content of sorghum plants. Preliminary research was conducted by planting three varieties of sorghum (Numbu, Super 1, and Super 2). Subsequent planting involved selecting the variety most resistant to drought based on data analysis of several parameters. The basic design used in this experiment was a completely randomized design (CRD) with one factor: the level of drought stress, which had four levels -no drought stress as a day 0 (control) and drought stress for 3, 6 and 9 days by withholding water. The results showed a decrease in the total chlorophyll content of the leaves over time. Drought stress for 6 and 9 days without watering resulted in water content dropping below 25%, indicating severe drought stress and disrupting plant growth. Severe drought stress was characterized by low soil and leaf water content, yellowing and curling of the leaves.

Abstract

SCMV (Sugarcane Mosaik Virus) is sugarcane crop disease resulting in chlorosis in leaves with the formation of the colors yellow and green intermittents. Based on survey information obtained that the air observation of all varieties of sugarcane was already stricken with the virus SCMV. Even the most formidable attack is on PS881 varieties with the intensity of the attacks reached 80%, so that it is estimated will lose up to 40% of the harvest. The sugarcane is virus free can be obtained via organogenesis in tissue culture method directly on the apical meristem, somatic embryogenesis at, and also with the addition of khemoterapeutan (acyclovir).The workings of the khemoterapi materials are the chemotherapi will interfere with replication and synthesis of genetic material of the virus but also cause the same effect against the mechanism of synthesis of nuklet acid on plants hosts. This research aims to find the best concentration and exposure time the most good in eliminating viruses SCMV in the apical bud culture of sugarcane PS881, using the antiviral acyclovir in conditions of invitro, so that the resulting plant will be virus free. The methods used to detect the presence of the virus by using the two ways, the first is by serology test through the protein content of the virus / checking nucleic acid virus with ELISA and the second is by RT-PCR. The results of the analysis showed that the interaction between the concentration of chemotherapy and exposure time produces the best treatment in eliminating the virus was . treatment with acyclovirc oncentration of 20 ppm and exposure time of 5 weeks.

Abstract

Wee1 is a gene encoding for protein kinase that is located in the nucleus and it plays an essential role in determining the timing of mitosis. Overexpression of Wee1 in rice is resulting in increased plant size. However, the increasing plant size due to the increase of Wee1 protein expression is not elucidated. Immunodiagnostic using specific antibodies against Wee1 protein should be conducted to determine the role of the protein on cell division. This experiment was directed to construct Wee1 in an expression vector for synthesis of recombinant Wee1 protein using three strategies of construction. The three strategies were construction of full length (FL), deletion of putative binding site (BS), and deletion of N-terminal domain (ΔN) of Wee1. Restriction analysis with BamH1/Sal1 of FL-Wee1, BS-Wee1, and ΔN-Wee1 construct resulted in the different DNA fragments with molecular size at 1239, 1176, and 960bp, respectively. This result indicated that the Wee1 fragments have been successfully inserted in the expression plasmid which was further confirmed using DNA sequencing. Colony PCR analysis showed that Escherichia coli strain BL21 (DE3) has been transformed with the constructs. The protein analysis using SDS-PAGE revealed that the recombinant protein of Wee1 synthesized in the E.coli containing ΔN-Wee1 construct, but not in FL-Wee1 and BS-Wee1 constructs. The ΔN-Wee1 protein was synthesized in an insoluble fraction with a molecular size of 38.8 kDa which is the same as the size estimated using the software ExPASy. Interestingly, the level of synthesized ΔN-Wee1 protein was not induced by IPTG concentration. Collectively, the results indicated that the DNA construct of ΔN-Wee1 is suitable for recombinant protein production.
