Abstract

Sugarcane (Saccharum officinarum L.) requires sufficient a water supply to produce optimal productivity. The selection of the superior varieties of sugarcane that are tolerant to drought can be done by molecular detection of the presence of the pyrroline-5-carboxylate synthetase (P5CS) gene. The research is aimed at molecular detection of P5CS gene in a commercial varieties at PT Gunung Madu Plantations (GMP), Indonesia that are potentially drought resistant. Similar research has never been conducted at PT GMP, as evidenced by the absence of official publications. The varieties used are GMP 3, GMP 5, RGM 06-654, PS 864, RGM 08-1026, PSJT 941, RGM 01-1834, GP11, RGM 07-099, and RGM 02-108. The research phases include DNA isolation, quantitative and qualitative DNA amplification, and PCR product visualization. Molecular data analysis is based on DNA band scoring results in the form of binary data which is then used to calculate the level of polimorphism information content (PIC) on the primary data used. The results of the study showed that nine out of ten varieties had P5CS-specific band sizes of ±167 bp, namely GMP 3, GMP 5, RGM 06-654, PS 864, PSJT 941, RGM 01-1834, GP 11, RGM 07-099, and RGM 02-108. A total of four of the nine varieties showed P5CS gene band thicknesses of RGM06-654, PSJT 941, PS864, and RGM 01-1834 which indicates the selected varieties most resistant to drought. The result of the PIC calculation has a value of > 0.25 which indicates the primary P5CS used is quite informative. The molecular detection was continued on one selected variety is PSJT 941, which showed that the relationship analysis of P5CS gene shows close affinity with the isolates from China and Bogor.

Abstract

This study utilized epoxy resin, three types of fabric (carbon fiber, glass fiber, and Kevlar), and two plasticizers – tricresyl phosphate (TCP) and oleic acid (OA) – to enhance the impact toughness of carbon fiber-reinforced plastics (CFRP). The polymer matrix used in the experiments was a hot-cured epoxy compound "Etal Inject-T" consisting of two components: A – epoxy resin and B – hardener, in a mass ratio of 100:49.9. For the fabrication of CFRP plates, both manual and vacuum molding techniques were employed. Combined reinforcement of carbon fiber was achieved using one of two types of fabrics: Ortex 360 glass fiber or Kevlar. Accordingly, two compositions were prepared for the experiments: carbon fiber/glass fiber and carbon fiber/Kevlar. Layer stacking in each composition was performed at ratios of 10:10 and 14:6, consisting of 20 layers in total. The greatest strengthening effect for CFRP in the case of carbon fiber/glass fiber was observed with a layer ratio of 14:6 and matrix modification using 10% TCP plasticizer. The strength of the CFRP increased from 425 to 451 MPa, and the impact toughness (α) improved from 192 to 280 kJ/m². A key feature of this technology is the achievement of high-performance dual-purpose CFRP. This enables the reduction of CFRP structures in aerospace applications by 3 to 5 times, while simultaneously enhancing resistance to impact loads.

Abstract

Diabetes mellitus is characterized by high blood sugar levels in the body. Treatment for type 1 diabetes mellitus is with insulin injections while treatment for type 2 diabetes mellitus generally uses oral medication. Currently, people are looking for diabetes drugs made from complex compounds using metals. The development of research and utilization of Fe(III) complex compounds is still limited, thus, in this study the synthesis of Fe(III) complex compounds with arginine ligands was carried out. The results of the research obtained a complex compound of Fe(III)-arginine with 96%, in the form of a brown gel with a sample weight of 0.5601 g. Characterization using a UV-Vis spectrophotometer showed absorption at a wavelength of 203 nm which indicated the absorption of the Fe(III)-arginine complex. The results of FTIR analysis showed a typical absorption of Fe–O and Fe–N bonds at a wavelength of 500–600 nm. The results of the calculation of the mice's body weight decreased when induced by alloxan. After 3 and 4 weeks, the mice's body weight returned to stability. The highest decrease in glucose levels was in dose 2, namely 100 μg/kg bw with a decrease in %GL of 66.72%. The results of this study show that the complex compound Fe(III) arginine can reduce blood glucose levels in mice.

Abstract

Bacterial infections pose significant threats to human health, particularly due to the rise of antibiotic-resistant strains. Identifying new sources of effective antibiotics is therefore crucial for combating these resistant pathogens. This study aims to isolate novel Streptomyces species and profile their secondary metabolites through extraction and high-resolution mass spectrometry (HRMS) analysis. Furthermore, the antibacterial activity of the extract containing the secondary metabolites was assessed through the in vitro agar well diffusion method and supported by the molecular docking, molecular dynamics simulations, and drug-likeness analysis. Sediment samples were collected from mangrove forests in Yogyakarta. The bacteria were then isolated, purified, and characterized using 16S rRNA sequencing. The isolates were then cultured to enrich the secondary metabolites, and their secondary metabolites were extracted using methanol and dichloromethane solvents in a 1:1 volume ratio. The results showed that the isolated bacteria of Streptomyces sp. were obtained with a 95.44% similarity rate, which produced several secondary metabolites. The in vitro antibacterial assay of the extract resulted in an inhibition zone of 14, 14, and 15 mm against Propionibacterium acnes, Staphylococcus aureus, and Escherichia coli, respectively. The molecular docking and molecular dynamic simulations for 100 ns revealed that compound SB236057A could inhibit the function of thymidylate kinase protein through a carbon-hydrogen bond with Glu37 residue. Furthermore, drug-likeness analysis showed that the secondary metabolites of Streptomyces sp. exhibited preferable drug-likeness and pharmacokinetic properties. This research focuses on the understanding of microbial biodiversity in mangrove sediments, particularly focusing on the genus Streptomyces and its potential to produce novel antibiotics.

Abstract

Lead is widely found in the environment and it is a heavy metal element that has a neurotoxic effect. Unlike other elements, lead does not provide its benefits in the human body. Neurotoxicity describes the neurophysiological changes caused by exposure to toxic agents, which can be manifested by changes in various functions of the nervous system. The aim of this research was to examine the associations between high school students' lead hair levels, intelligence quotient (IQ) scores, propensities for antisocial behavior, and hand grip strength. This research used canonical correlation analysis. Lead levels were detection by flame atomic absorption spectrometry (AAS). Antisocial behavior tendency data was measured using a 21-item antisocial tendency scale using the aspects listed in diagnostic statistical mental disorder (DSM) V which had previously been tested for validity and the reliability. The IQ level was measured using the Wechsler adult intelligence scale (WAIS) test, while the hand muscle strength test was measured using a hand grip dynamometer. Based on the results of the canonical correlation analysis, the research results showed that there was no correlation between lead levels in hair and antisocial behavior tendencies, but there was a relationship between lead levels in hair and IQ levels and hand muscle strength.

Abstract

Mangrove endophytic fungi can produce bioactive substances with diverse  biological functions. This study aims to evaluate the chemical profile of mangrove fungal endophytic extracts that inhibit clinical pathogenic bacteria resistant to various antibiotics. The fungi were collected from Petengoran mangrove forest, Lampung Province. Fungal isolates were grown on shrimp shell media using solid-state fermentation for 14 days. The fungal biomass was extracted using ethyl acetate, and the active components were evaluated using thin layer chromatography. The extract was partitioned with dichloromethane/water and its bioactivity was tested using TLC-bioautography and agar diffusion methods. The active fraction was identified using LC-MS/MS. The LC-MS/MS data was interpreted with SIRIUS 5.8.6, and the drug-likeness and toxicological characteristics were assessed using ADME/Tox and STopTox machine learning tools. Morphological analysis showed that isolate 22PLP1F1 was an Aspergillus sp., with spherical conidia at the hyphae tips. Through phylogenetic analysis it was confirmed that isolate 22PLP1F1 is Aspergillus sydowii with similarity 98.9%. Initial TLC examination indicated the production of alkaloids, polypeptides, and steroids. Antibacterial assays showed that the polar portion inhibited multi-drug resistance (MDR) Staphylococcus aureus, while the active fraction at 2 mg/mL inhibited MDR Pseudomonas aeruginosa. LC-MS/MS analysis revealed a major chromatogram peak at a retention time of 8.67; m/z 488.2196, suggesting a novel derivative of a compound at a retention time of 7.82; m/z 446.208. ADME/Tox analysis indicated that the compounds do not penetrate the BBB but remain in the GI absorption region. Further research is needed to elucidate the active compounds’ mechanism of action and conduct bioengineering studies.

Abstract

Ecosystem recovery plays a central role in environmental and forest conservation efforts, including efforts made in a conservation area that is a national park. This effort requires support from the communities living around the national park. Therefore, the presence of the community can become a form of capital, which is generally referred to as social capital and will determine the success of a program. Elements of social capital consist of trust, norms, and networks is one form of capital that is very valuable in addition to economic capital, physical capital, and human capital. The purpose of this research is to analyze the level of social capital that exists in the community and how the characteristics of respondents affect social capital. This research is located in Labuhan Ratu VII Village, Labuhan Ratu Subdistrict, East Lampung Regency from November to December 2023. Based on the results of the analysis, it is known that the trust element and the social network element are in the medium category, while the norm element is in the high category. Education and length of stay are respondent characteristics that influence community social capital in supporting ecosystem recovery in Rawa Kidang, Way Kambas National Park (WKNP). Increasing social capital can be done through two characteristics that affect community social capital in the form of informal education such as training. People who live for a long time will affect the sustainability of WKNP so training can be carried out for a long period of time in a structured and intensive manner towards sustainable WKNP management. The results of this study can be a consideration for WKNP managers in implementing Permen LHK policy no 14 of 2023 concerning business and/or activity arrangements in nature conservation areas, nature reserve areas and hunting arks because they must have a strong social foundation.

Abstract

Saccharomyces-modified tempeh (SM tempeh), which is produced by adding Saccharomyces cerevisiae during soybean fermentation, is considered to have the potential as a source of prebiotics. The research aims to determine the prebiotic activity score (PAS) of SM tempeh extract against the probiotics S. cerevisiae and Lactobacillus casei, as well as to evaluate the resistance of S. cerevisiae and Escherichia coli in the intestines of mice fed tempeh. The PAS evaluation was carried out using a factorial complete randomized block design with three replications and one-way ANOVA for data analysis followed by the least significant difference test (5%). Meanwhile, microbial survivability was carried out in vivo using male Mus musculus strain mice fed standard feed, and standard feed with tempeh extract supplementation. The results showed that the supplemetation of either SM or commercial tempeh extract to the growth media significantly affected on the microbial load of S. cerevisiae, L. casei and E. coli, but the concentrations of tempeh extract had no significant effect. Apart from that, the concentrations of tempeh extract had no effect on the PAS of S. cerevisiae and L. casei, meaning that it was able to promote the growth of probiotics in the amount added to the media in the range of 2–10%. In addition, the feeding type had a significant effect on the survival of S. cerevisiae and E. coli in the intestines. S. cerevisiae carried on SM tempeh was detected surviving in the mice intestine at a rate of 6.12 log CFU/g, indicating that the tempeh was a probiotic food. Most likely SM tempeh is a synbiotic food.

Abstract

Most of the global population lives in urban areas, which also serve as hubs of economy, industry, and government activities. Various factors that affect the quality of cities have been studied in different locations. This article reviews various papers that examine environmental quality indicators in urban areas that can be extracted from remote sensing data. The first aspect is vegetation cover, which is known from the vegetation index normalized difference vegetation index (NVDI), and the second aspect is surface temperature, which is known from land surface temperature (LST). In this work, urban environmental conditions in various countries are compared with urban conditions in Indonesia based on these indicators. It is found that NDVI and LST are indicators from remote sensing that are widely used to analyze urban environmental conditions. The vegetation index has a negative correlation with surface temperature. High surface temperature creates discomfort in urban quality of life and brings mental stress to residents living in those areas. Based on bibliometric analysis and network map, it is known that there are 30 most relevant words or terms to the keywords “urban remote sensing” and “remote sensing environment indicator” with the highest frequency of occurrence and relevance. This study can serve as input for the government as policymakers and urban planners to formulate spatial planning policies oriented towards sustainability and to research current topics related and relevant to remote sensing-based urban environmental quality indicators.

Abstract

Limberry (Triphasia trifolia) is one of traditional medicinal plants whereas its leaves are known for various uses, one of which is as an antibacterial agent. The most common bacteria found in marine waters is Vibrio sp. This work seeks to distinguish antibacterial compounds inside the ethanol extract of limberry leaves and assess its repressive effect on Vibrio sp. The research was conducted with three repetitions and five different concentration levels: D1 (5%), D2 (10%), D3 (15%), D4 (20%), and D5 (25%). The observational data were analyzed using a completely randomized design (CRD) analysis of variance, followed by the least significant difference (LSD) test at a 5% significance level. Phytochemical screening revealed that the ethanol extract of limberry leaves contained antibacterial compounds namely flavonoids, tannins, steroids, alkaloids, and phenolics. UV-Vis spectrophotometry analysis indicated that the ethanol extract of limberry leaves had absorption at wavelengths of 202, 211, 228, 253, 270, and 323 nm. FTIR analysis showed that the ethanol extract of limberry leaves contained some functional groups, i.e., O–H, C–H alkanes, C–H alkenes C≡N, C=O, C=C, C–O esters, and C–O ethers. The inhibitory test also demonstrated that the ethanol extract of limberry leaves could inhibit the growth of Vibrio sp., with inhibition zone diameters formed at each concentration of 5%, 10%, 15%, 20%, and 25% being 7.280, 7.640, 7.713, 8.027, and 8.070 mm, respectively.
