Physical, thermal, and mechanical properties of polypropylene composites filled with rattan nanoparticles

Natural fillers are recognized as the materials that feature a poor fiber/matrix interaction. As a result, their composites behaviors are directly compromised. Existing evidence has exhibited that nanoparticle fillers can be employed as an alternative size to overcome this problem. We thus examined in this study the effects of rattan filler of nanoparticle size on the physical, thermal, and mechanical properties of the composite. Neat polypropylene (PP), PP with 5% rattan nanoparticle (PP/R5), and PP with 5% glass fiber (PP/FG5) were considered. For performance assessment, particle size analysis, morphology, X-ray diffraction, thermal inspection, and mechanical tests were carried out. The highest degree of crystallinity was discovered in PP/R5. Tensile properties of both PP/FG5 and PP/R5 were comparable although the former demonstrated higher moduli of elasticity and rupture. Well-distributed constituents were displayed in PP/R5 by means of morphological study, which offered insight into its highest average hardness, maximum strain, and therefore its advantageous ductile behavior compared to the other considered materials

THE AUTHORITY OF POLICE INVESTIGATORS IN ERADICATION OF CRIMINAL ACTS OF CORRUPTION

Law Number 19 of 2019 concerning the Law on Corruption Eradication Commission which is a renewal of Law Number 31 of 1999 as amended by Law Law No. 20 of 2001 concerning Eradication of Corruption, instead of Law number 3 of 1971. The enactment of this law is expected to accelerate the growth of people’s welfare, responding to the evil nature contained in corruption. The problem in this study is how is the authority of police investigators in eradicating criminal acts of corruption after the issuance of Law Number 19 of 2019 concerning Law on Corruption Eradication Commission and what obstacles faced by investigators related to the authority of police investigators in eradicating criminal acts of corruption after the issuance of Law on Corruption Law Number 19 of 2019 concerning Law on Corruption Eradication Commission. The method in this study uses descriptive qualitative research methods with a normative juridical approach. The results of this study are : (1) The authority of police investigators is to carry out investigations. Investigation activities are a follow-up to investigations that have found the construction of corruption crimes that have occurred to some extent. The law gives special rights or privileges to investigators to carry out investigative functions such as summoning, examining, arresting, detaining, confiscating, and determining suspects. (2) The obstacles faced concerning the authority of police investigators are a) The number of members of criminal investigators is limited. b) Information received regarding criminal acts of corruption is still unclear and in detail. c) Operating costs that have not been met. d) Lack of public legal awareness. The solution to the obstacles faced is by a) Gradually increasing the number of criminal investigators. b) Speed up all access to information related to criminal acts of corruption. c) The government needs to increase the operational cost budget item. d) It is necessary to hold outreach to the community either directly or through electronic media or social media

Green synthesis of silver nanoparticles using muntingia calabura leaf extract and evaluation of antibacterial activities

The present work aims to investigate a green synthesis of AgNPs using Muntingia calabura leaf extract as reducing and stabilizing agents. The AgNPs formation was monitored using UV-Vis spectrophotometer. Characterisations of AgNPs size and shape were observed by TEM. The elemental analysis was analyzed using XDS. The maximum surface Plasmon resonance for AgNPs was detected at 425-430 nm. This study revealed that the AgNPs were polydispersed and polycrystalline nature. The microbial inhibition test against Escherichia coli and Bacillus cereus showed that the muntingia leaf-mediated AgNPs had inhibited the growth of these bacteria, as indicated by the formation of inhibition zone. The average inhibition zone for Escherichia coli was 10.3±0.5 mm and for Bacillus cereus at 9.5±0.6 mm. TEM results showed that the synthesised AgNPs have spherical form with the sizes ranging from 22 to 37 nm. Hence, the synthesised AgNPs can potentially be applied for water treatment and medicinal purposes

SEAGRASS DISTRIBUTION BASED ON THEIR SEDIMENT CHARACTERISTICS IN PUNTONDO WATERS, TAKALAR DISTRICT, SOUTH SULAWESI, INDONESIA

Seagrass distribution is influenced by many factors, including sediment characteristics. This study aims to determine the distribution of seagrass based on their sediment characteristics. Observations and sampling were carried out in the waters of the Puntondo Bay, Takalar Regency. This study observed the cover and density of seagrass species, water depth, water transparency, sediment’s total organic matter and size of sediment grains. There were five species of seagrass found in the area, namely Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, Halophila ovalis and Syringodium isoetifolium with sediment types of medium sand and coarse sand. Results of the regression analysis showed that the relationship between sediment particle size and seagrass density with the  highest coeficient determination (R2=0,3346) was in seagrass Cymodocea rotundata, whereas the lowest was in  Syringodium isoetifolium. Keywords: Seagrass, Puntondo, aters, Sediment grain size, Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, Halophila ovalis, Syringodium isoetifolium

Nutritional Status of Toddler Children in Cikoang Village, Mangarabombang District, Takalar District

Nutritional status is the end result of the balance between the food that enters the body (nutrient input) and the body's need (nutrient output) for those nutrients. In other words, the state of the body as a result of food consumption and the use of nutrients. Nutrient requirements are determined by many factors, including: basal metabolic rate, growth rate, physical activity, and relative factors, namely: ingestion, differences in absorption, utilization, and differences in excretion and destruction of nutrients in the body. A sample of 82 children aged between 2.5 and 5.0 years and 114 households representing adulthood was observed in two villages with Maudu' rituals, and 99 and 134 households in two villages without Maudu' rituals. The research was conducted in Cikoang Village, Takalar District. The results of this study indicate that the nutritional status of children under five in Cikoang Village is not good and needs attention from related parties in helping to improve child nutrition in Cikoang Village

Novel weed-extracted silver nanoparticles and their antibacterial appraisal against a rare bacterium from river and sewage treatment plan

This is the first investigation to demonstrate the use of biochemical contents present within Cyperus rotundus, Eleusin indica, Euphorbia hirta, Melastoma malabathricum, Clidemia hirta and Pachyrhizus erosus extracts for the reduction of silver ion to silver nanoparticles (AgNPs) form. In addition, the antibacterial capability of the synthesized AgNPs and plant extracts alone against a rare bacterium, Chromobacterium haemolyticum (C. haemolyticum), was examined. Moreover, ultraviolet-visible spectroscopy (UV-vis), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDX) and inductively coupled plasma atomic emission spectroscopy (ICPOES) of the synthesized AgNPs were characterized. The smallest AgNPs can be produced when Cyperus rotundus extracts were utilized. In addition, this study has found that the synthesis efficiencies using all plant extracts are in the range of 72% to 91% with the highest percentage achieved when Eleusin indica extract was employed. All synthesized AgNPs have antibacterial capability against all examined bacteria depending on their size and bacteria types. Interestingly, Melastoma malabathricum and Clidemia hirta extracts have demonstrated an antibacterial ability against C. haemolyticum
