IDENTIFICATION OF INDONESIAN ETHNOMEDICINAL PLANTS AS POTENTIAL DRUG CANDIDATES FOR ACUTE RESPIRATORY INFECTION USING COMPUTER-AIDED DRUG DESIGN AND SIMRS MODEL
Full text linkIn 2023, Indonesia’s air quality deteriorated, with its Air Quality Index (AQI) tripling clean air standards, causing health sector losses, including a surge in Acute Respiratory Infection (ARI) cases. One of the ARI treatments is the consumption of cefuroxime, yet it can cause side effects. Indonesia’s floral biodiversity in ethnomedicinal plants can be utilized as a more natural drug candidate for ARI drugs. To determine this, an in silico approach is performed through molecular docking, and Pre-ADMET prediction. Based on the compound selection’s results, lanosterol is the most promising compound, with a binding energy value of -8.11 kcal/mol and an efficiency of 78.81%, while cefuroxime as a reference ligand has a binding energy value of -5.92 kcal/mol with an efficiency of 67.87%. After undergoing compound selection, a time series analysis through the Susceptible Infected Medicine Recovered Susceptible (SIMRS) model is conducted. In this analysis, it is found that cefuroxime and lanosterol require the same amount of time, which is 33 days to restore Indonesia to its pre-ARI outbreak condition, indicating that lanosterol can be used as an alternative drug candidate
POTENTIAL OF ENCAPSULATION Bacillus cereus BTH-22 AGAINTS BACTERIAL WILT DISEASE ON EGGPLANT: -
Full text linkEndophytic bacteria are a group of bacteria that live in plant tissues, potentially as biological agents of plant diseases, especially wilt disease caused by Ralstonia solanacearum and as an inducer of eggplant (Solanum melongena) plant growth. One of these bacteria is Bacillus cereus BTH-22 which was isolated from healthy eggplant stems in Kediri. The purpose and formulation of the problem are to obtain an encapsulation formulation of B. cereus BTH-22 which has the potential as a biological agent against wilt disease caused by R. solanacearum and as an inducer of eggplant (S. melongena) plant growth. The novelty of the research is the encapsulation formulation of B. cereus which is applied to eggplant plants with wilt, because the application generally uses root soaking, watering to the soil surface, mixing with fertilizer, liquid and powder formulations but all are easily washed away by rain. The research method is as follows: (1) Making encapsulation formulation: 75% Na-alginate with 10% aloe vera extract (Na-1) and 75% Na-alginate, 0.875% zeolite and 0.875% sago flour (Na-2), (2) Sterile soil, inoculate R. solanacearum and prepare 1 month old plants, (3) Application of encapsulation formulation was carried out 3 days after inoculation of R. solanacearum (107CFU/mL) using a Completely Randomized Design with 3 replications. Observations were made on days 7, 14, 21, 28, 35, 42, 49 including : disease intensity, plant height, number of leaves, number of flowers. The results of the study showed: viability in the Na-1 and Na-2 treatments was higher than control at the 48th to 96th hours, disease intensity in the Na-1 and Na-2 treatments was lower than control at the 7th to 49th day, plant height in the Na-1 and Na-2 treatments was higher than control at the 14th to 49th day
THE EFFECT OF LONG SOAKING OF SEEDS IN KNO3 SOLUTION AND VARIATIONS IN PLANTING MEDIA ON THE GERMINATION OF CIPLUKAN (Physalis angulata L.) SEEDS IN VITRO
Full text linkThe Physalis angulata L. (ciplukan), originating from the Solanaceae family, contains secondary metabolites that can be used as medicinal materials. The provision of Physalis angulata seeds is hindered by seed dormancy. Dormancy can be broken by employing a 0.2% w/v KNO3 solution with a specific soaking period. This study aims to optimise the duration of the soaking period for Physalis angulata seed germination and the in vitro growing medium. The seeds were soaked in a 0.2% w/v KNO3 solution for 6 hours, 12 hours, and 24 hours. The soaked seeds were planted in sterile tissue media moistened with Murashige and Skoog (MS) medium solution, a 0.2% w/v KNO3 solution, and distilled water. Generally, the dormancy of Physalis angulata seeds can be broken by soaking them in a 0.2% w/v KNO3 solution. The results of this study indicated that Physalis angulata seeds soaked in a 0.2% w/v KNO3 solution for 6 hours and 12 hours, then planted in sterile tissue media moistened with the MS medium solution, exhibited an optimal germination response

Full text linkThe mRNA expression system has revolutionised biotechnology, notably in viral mRNA vaccine development, cancer immunotherapy, and gene therapy. However, recent safety concerns regarding the COVID-19 mRNA vaccine have emerged, particularly regarding its rare adverse effects and its possible connection to cancer. This review explains several approaches used in developing viral mRNA vaccines, the past obstacles solved in generating the current COVID-19 mRNA vaccine, and finally the current advancements and ongoing challenges in the viral mRNA vaccine field. We particularly focus on strategies and methods to improve the safety and translation efficiency of the mRNA vaccine, such as enhancing the vaccine’s transfection specificity to targeted dendritic cells (DC) and using viral IRES or self-amplifying mRNA format to improve mRNA translation efficiency
UTILIZATION OF FISH PROTEIN HYDROLYSATE AS A NITROGEN SOURCE IN FERMENTED MEDIA OF CEPHALOSPORIN C PRODUCTION BY ACREMONIUM CHRYSOGENUM Biomcc 00141
Full text linkOptimizing Indonesia's maritime resources as an effort to reduce reliance on imported raw materials for the pharmaceutical industry. This study investigates the use of fish protein hydrolysate, derived from trash fish flour, as a supplement in the fermentation process for producing cephalosporin C. This key raw material is used to create cephalosporin antibiotics through fermentation with the fungus Acremonium chrysogenum Biomcc 0141. Hydrolysate from trash fish flour is obtained through an enzymatic hydrolysis process using a protease found in pineapple hump extract which was optimized. The results of hydrolysis optimization on hydrolysate from trash fish flour produce a protein content of 3.37%. The protein hydrolysate obtained is then used in the cephalosporin C fermentation process. The addition of trash fish protein hydrolysate to cephalosporin C fermentation media showed a significant increase in the productivity of cephalosporin C, which is up to 85.39% higher than the fermentation process without the addition of fish protein hydrolysates
IN SILICO ANALYSIS OF SMALL INTERFERING RNA TARGETING THE NUCLEOPROTEIN GENE OF INFLUENZA VIRUSES
Full text linkSmall interfering RNA (siRNA) is a promising therapeutic against viral infection, includ-ing Influenza viruses. However, the Influenza viruses have massive variants with high mutation rates. Therefore, the siRNAs could be futile against newly emerging viruses. Thus, this study aimed to analyze siRNAs targeting the nucleoprotein gene of Influen-za viruses. Using bioinformatic analyses, the siRNAs were simulated against 5 sub-types of Influenza viruses, including H1N1, H3N2, H5N1, H7N9, and H9N2. Bioinfor-matic tools for the folding structure of messenger RNA were utilized to select effective siRNA. As a result, 32 siRNA sequences targeting the nucleoprotein gene were identi-fied. The precision medicine concept seems applied to the siRNA treatment for the In-fluenza virus since each siRNA is effective in its respective virus target. Based on the nucleotide mismatch parameter, most siRNA does not have coverage for the multiple infections of all five subtypes of Influenza viruses, except for NP1089 and NP1496. Later, the secondary and tertiary structure analysis of messenger RNA demonstrated that siRNA has different circumstances in its RNA target position. Therefore, siRNA mapping based on the RNA folding structure approach provides a tool for selecting more effective sequences against Influenza virus infection. Both siRNA NP1089 and NP1496 were predicted to have similar effectivity in knocking down Influenza virus in-fection. Moreover, the cocktail application of siRNA treatment may be effective as an alternative strategy in matching co-infection of multiple Influenza virus subtypes
OPTIMIZING AMOUNT AND IDENTIFICATION OF YEAST IN SALAK YEAST WATER (Salacca edulis Reinw cv Pondoh)
Full text linkSalak fruit is a tropical fruit spread across Southeast Asia and can potentially be a source of natural yeast by processing fruit yeast water. Salak fruit is known to be rich in carbohydrates, making it a potential natural habitat for microbial communities, especially yeast. This research aims to optimize the growth of yeast in the salak yeast water system by varying the sugar concentration treatment, the composition of the amount of fruit flesh, and the fermentation time, as well as identifying the yeast in the salak yeast water. The method used is to count the number of yeast colonies using the Total Plate Count method. The most optimal treatment results are then tested for pH, total sugar, alcohol, isolation and yeast identification. The research results showed that the composition of salak meat was 30%, adding 1% sugar, and fermentation for 6 days resulted in the most optimal growth of the microbial community with an amount of 3.1×10⁶ cfu/ml. The pH test showed a result of 3.01, the alcohol content, namely ethanol, was 0.066855%, no methanol was detected, the total sugar test result in the yeast water was 2.08%, and it was identified in the yeast water that there were Hanseniaspora opuntiae and Candida sorboxylosa. The results show that salak yeast water (Salacca edulis Reinw cv Pondoh) can be used as a yeast water product to ferment food
OPTIMIZATION OF METHANE PRODUCTION FROM MIXED SUBSTRATES OF COW FAECES AND CARICA SEEDS USING RESPOND SURFACE METHODOLOGY
Full text linkAnaerobic digestion (AD) of dairy cow feces (DCF) has low methane production per ton of waste. A strategy to overcome this drawback is to co-digest DCF and carica seed (CS). Currently, CS is still a waste from the candied carica in the syrup industry and is often just thrown away into the environment. This research aims to evaluate the optimal level of combination for methane production from DCF with co-substrates of germinated (CGM) and non-germinated (CNG) CS meal using Respond Surface Methodology (RSM). This research uses a completely randomized design with a factorial pattern consisting of the first factor being CGM and CNG, and the second factor being the combined level of DCF and CS (CGM or CNG. The result showed that utilization of CS can increase significantly (p<0.05) methane production of the final substrate compared to the control (digester treating DCF only). Utilization of CGM as co-substrate with DCF can also increase methane production (p<0.05) compared to CNG. All parameters in the liquid phase were in the normal range for AD. Based on the research results, the optimum point with a desirability value close to 1 was achieved at a ratio of CGM10 and DCF90. CS was proven can be used as a co-substrate with DCF to increase methane production of the final substrate and germination can be used as a method to increase the methane yield of CS.
UTILIZATION OF OIL PALM EMPTY FRUIT BUNCHES ENHANCED WITH MOLASSES FOR XYLITOL PRODUCTION
Full text linkA minimal oil palm empty fruit bunch (OPEFB) usage encourages increased OPEFB utilization to prevent its loss of economic prospects. The xylose and arabinose constituents of OPEFB’s hemicellulose part can be utilized as raw materials for xylitol production. A high diabetes mellitus and periodontal disease prevalence in Indonesia makes xylitol a safe and helpful low-calorie sweetener alternative. This research explores the OPEFB molasses-supplemented media and compares Moniliella pollinis SP5 and other M. pollinis ethyl methanesulfonate (EMS) mutants in xylitol yields. It was found that M. pollinis SP5 accomplished 27% better performance in OPEFB+15%(v/v) molasses than in OPEFB from 0.48 g/g to 0.61 g/g. In addition, M4, M5, and M6 mutants from EMS mutagenesis generated more xylitol concentration in OPEFB + 15%(v/v) molasses compared to the SP5 strain. These findings provide in-sights into the potential of xylitol manufacture with OPEFB. For future research, it is recommended that xylitol production employing OPEFB be optimized
UTILIZATION OF PINEAPPLE PROCESSING LIQUID WASTE IN BIODEGRADATION OF DISPOSABLE FACE MASK BY BACTERIA FROM LAMPUNG BAY
Full text linkThe designation of COVID-19 as a global pandemic led to an increased use of single-use face masks, which result in waste that is difficult to degrade and has the potential to release microplastic fibers into the environment. This study aims to examine the im-pact of adding pineapple peel liquid waste (LCN) as a growth medium for the biodeg-radation of single-use face masks by bacterial isolates obtained from the waters of the Lampung Bay. The study investigates how LCN affects the efficiency of mask degra-dation by microorganisms, as well as how the ratio of LCN mixed with other growth media, such as Nutrient Broth (NB), influences the degradation process. The biodeg-radation process was carried out using a biostimulation technique, where bacterial iso-lates were incubated in media containing LCN at a 1:1 ratio. The degradation process lasted for 15 days, with the results being analyzed using gravimetry and Fourier-Transform Infrared Spectroscopy (FTIR). Gravimetric results showed a greater weight reduction in treated masks compared to the control masks. FTIR analysis also indicat-ed changes in the intensity of functional groups in the degraded layers of the masks, as well as the emergence of C≡C functional groups in the second and third layers. This study demonstrates that the addition of LCN can accelerate the biodegradation of sin-gle-use face masks, offering a new approach for managing mask waste
