Abstract

Alternative therapies are being sought as a result of the rising concerns with inadequate and untrustworthy medical treatments for Shigella flexneri. The current study aimed to assess the preventive and therapeutic effects of crude pili S. flexneri on of neutral pH and cold temperature against Shigella flexneri infection in immunocompetent mice. Twenty male Swiss albino mice were randomly assigned to one of two groups: control or experimental groups. Each group was subsequently separated into four equal subgroups. In order to infect the mice, 4 weeks before infection, the experimental subgroups were given crude pili S. flexneri orally in every week (three times) until the completion of the research. After following the treatment of crude pili S. flexneri, all group infected with Shigella flexneri. The small intestines of mice were processed and analyzed for the presence of the pathological lesions. Jejunal portions were measured. The findings revealed that vaccinated mice had a statistically significant increase in the quantity of health mucose as compared to non-infected group in ileal sections. Crude pili S. flexneri was administered to the intestinal portions of all subgroups before or after the infection, and the architecture was found to be more or less normal. Our data indicate that crude pili S. flexneri in neutral pH and cold temperature is a useful preventative and a potentially effective treatment medication for S. flexneri infection.

Abstract

Issues related to energy sustainability and carbon emission reduction are continuously being concerned by the Government of the Republic of Indonesia. Various efforts and programs have been launched to achieve targets of the related issues. As known that energy use for cooking by the household is continuously increasing in relation to population growth that will of course increase in energy need which relates to the sustainability of presence energy and carbon emission. Accordingly, the LPG stove conversion program to an electric stove was introduced in order to achieve the target to solve such issues. This paper compared of efficiency and carbon emissions of both electric filament stoves and induction stoves. The result indicated that the induction stove has better efficiency compared with the electric stove. The study also was proved that the carbon emissions for both types of stoves were relatively low in comparison with LPG stoves. However, the enormous operational power of the induction stove is still a challenge that must be resolved to achieve the target of energy sustainability in Indonesia.

Abstract

This study was aimed to know the effect of B2O3(boria) addition on the phase composition and physical properties of zircon ceramics.The raw zircon powder used in the study was a purified natural zircon sand from Kereng Pangi, Central Kalimantan, Indonesia. The zircon ceramics were prepared by a solid state reaction method with variation of B2O3 addition of 3 wt%, 6 wt% and 9 wt% and sintered at 1300 °C for 5h. The phase composition, density and microstructure were characterized using X-ray diffraction (XRD), densimeter and Scanning Electron Microscope (SEM), respectively. Vickers Hardness measurement was perfomed at the polished surface of the ceramics. Results showed that all samples contained pure zircon phase, i.e. there was no effect of B2O3 addition on the phase composition. In general, the density and hardness increased with increasing B2O3 addition, but addition up to 9 wt% is not optimum to achieve ultra-dense zircon ceramics. Furthermore, the SEM image also showed no significant difference in average grain size. The crystallite size has grown nearly eight times (325 nm) of its original powder. The Vickers hardness of the ceramics is not significantly influenced by the addition of boria. It appears that the boria failure to increase densification also results in the extent of contact between grains which then produces relatively large zircon grains.

Abstract

A Study on the development of a Testing Experiments model has been carried out which aims to improve the scientific abilities of students in the Physics Department. This study is motivated by the implementation of practicum that has almost no innovation, no change, always verifying patterned and less developing students' science process skills. The 4-D model RD approach was used to develop this practicum model. The instrument used is a handout that is equipped with a rubric as a practical guide and assessment guide. A total of 20 students were involved as research subjects. The results showed, in general, there was an increase in student scientific abilities. Of all the sub-abilities developed, the average percentage of achievement scores reached 60% in almost all sub-abilities after the 4th or 5th practicum or at the fourth or fifth week. However, there are sub-skills already reaching 60% in the 3rd practicum. Student and peer responses show that this practical model is better and more comprehensive in developing students' scientific abilities.

Abstract

Clay material from Rendeng, Malo, Bojonegoro was studied by mineralogy and physicochemical characterization to evaluate its potential suitability as a raw material in pottery application. X-ray Diffraction (XRD) and Fourier Transform-Infrared (FTIR) spectrometry were used to establish the mineralogy composition. Meanwhile the physical properties were identified by particle size distribution and consistency limits. Chemical composition was carried out by X-ray Fluorescence Spectrometer (XRF).  The results of XRD characterization revealed that clay from Rendeng Village, Malo, Bojonegoro contained  kaolin, quartz, and feldspar. Physical characterization shows that clay material is a less plastic type based on Atterberg method. Based on the chemical compositions indicated that SiO2, Al2O3, CaO, and Fe2O3 were abundance oxides. Therefore, clay from Desa Rendeng was only suitable for the pottery purposes because most of its mineral compositions did not meet the quality requirements for making advanced ceramics.

Abstract

The increasing number of traditional boats made from wood can cause the forest to be deforested. Besides, it also results in scarcity and an increase in the price of basic wood materials so that production costs are increasingly expensive—also, the factors of decay by mould, heating, weathering. One of the efforts that can be made in the traditional shipbuilding process is through making boats made from cheap and high-quality E-Glass fibre laminate composite boards. The purpose of this study was to determine the effect of volume composition of E-glass fibres and scallop shell particles on the tensile strength of hybrid composites. Making hybrid composites by mixing scallop shell filler, E-Glass fibre and matrix. Percentage volume fraction 0C: 0E, 10C: 20E, 15C: 15E and 20C: 10E. The results showed that the maximum tensile strength at the volume fraction of 10C: 20E was 34.15567 MPa, this result was higher than the maximum requirements set by BSN in 2006, namely 0.304 MPa. The existence of a strong bond between the fibres and the matrix can increase the tensile strength of the composite as well as the influence of the scallop shell particles which can help the matrix to accept external loads/stresses so that the composite strength increases.

Abstract

Until now, the world is still facing the spread of the SARS-CoV-2 virus that causes COVID-19. This virus can be transmitted from human to human through droplets, so more vigilance is needed to avoid contracting this virus. One of the steps to minimize the spread of Covid-19 is to wear a face mask. In practice, most people prefer to use cloth masks than disposable medical masks because they are cheap and reusable. Cloth pore size influences the filtering ability of the cloth masks. Therefore, it is necessary to analyze the efficiencies of the cloth masks. In this study, we developed a method for measuring the pores of a cloth mask using a smartphone. In this study, we developed a method for measuring the pores of a cloth mask using a smartphone. We used the camera zoom application on a smartphone and analyzed the image using image processing software, ImageJ. We appliedHuang's algorithm to adjust the image binarization threshold then calculated the Feret diameter as the pore size of the mask. According to the analysis, the pore size ranged from 0.133 to 0.232 mm, and the efficiency ranged from 77.4 to 82.6%.

Abstract

The drying process on kemplang crackers is one of the factors that determine the quality of the resulting product. Conventional drying has many disadvantages, namely fluctuating heat and poor hygiene that will affect product quality. So that kemplang crackers can be stored for a long time, it is necessary to reduce the water content of kemplang crackers. Drying kemplang crackers can use a drying rack with a biomass energy source from coconut shells. This study aims to design a tray dryer with biomass energy to obtain dryer performance based on the drying rate and to obtain a product that meets SNI No. 8272-2016. The treatments that were varied were set point temperatures of 55oC, 60oC, 65oC, and 70oC with mass variations of 50 gr, 100 gr, and 150 gr. The results showed that the optimum drying conditions at 70oC for 4 hours with an air velocity of 5.2 m/s2 obtained 9,84% moisture content in 50 gr kemplang crackers, 15.39% in 100 gr crackers and 19,2 in kemplang crackers 150 gr and a drying rate of 0,035028 kg/hour m2. The drying process requires 5,24 kg of dried coconut shell to produce heat energy of 95.358,81024 KJ with a by-product in the form of liquid smoke.

Abstract

Osteoporosis or bone loss is a chronic disease characterized by low bone mass accompanied by changes in micro-architecture of the bone and a decrease in the quality of bone tissue that can cause bone fragility, so that bones are easily cracked or even fractured. Osteoporosis is diagnosed by measuring bone mineral density using DXA (dual-energy X-rayabsorptiometry). Treatment with device this expensive and not widely available. So it is necessary to find an alternative method of detecting a cheap one. This study aims as an initial study to find an alternative way of early detection of osteoporosis by looking for the texture characteristics of the human bone. Sample in This study took 19 people with inclusion criteria including postmenopausal women who declared healthy, not broken bone and has no skeletal abnormalities since birth. Sample measured density mineral bone(BMD) or the degree of osteoporosis with DXA. Then an X-ray is done to get bone image. The stages of the research are: 1) preprocessing X-ray image of the human bone; 2) determine the value of the texture of the human bone image with gray level method co-occurrence matrix 3) test connection between the value of the human bone texture image with BMD lumbar spine. The results of the correlation test show that there is correlation between the value of human bone texture and BMD of the lumbar spine to characterize variance and significantly statistics (P0.05).
