Published: December 2020

Abstract
The article is devoted to the development of microwave technology and installations for preparing frozen cow colostrum for calf feeding by exposure to an ultrahigh-frequency electromagnetic field in two volume resonators, which allow defrosting and heating of cow colostrum at different doses in a continuous mode. Two resonator microwave installations designed for farms have been developed and described. Effective modes of defrosting and warming up cow colostrum in an electromagnetic field of ultrahigh frequency: duration of exposure to ultra-high frequency electromagnetic field in a resonator is 12 min; power of microwave generators 3.5–3.65 kW; plant productivity 25–30 kg/h; energy costs for the process 0.12–0.18 kW-kg/h, heating temperature of raw materials to 38–40 °C. For cattle farms up to 600 heads, one microwave installation is enough to defrost and heat cow colostrum. The annual economic effect due to lower operating costs will be 153600 rubles. The profitability of the process will increase by 3.22%.

Abstract
During the traditional mechanized harvesting of cabbage the heads are severely injured. In this regard, the purpose of research is to provide scientific justification for the new technology and devices for machine harvesting cabbage in a sparing mode. Using mathematical modeling, new methods of cabbage harvesting are justified, which provide for a gentle mode of shipment of heads by a combine harvester using a special device, first on a flexible flooring, and then carefully transferring them manually into containers. Thus, the methods of reducing the damage to cabbage heads during machine cleaning are formulated, and the nature of the influence of the main parameters of the proposed devices on the quality of the working process is analytically revealed. As a result, the rational parameters of the devices were determined: the departure of the loading zone of the tray Δ=0.100-0.150 m with its Flexural stiffness EI=16-20 H.m2
, the height difference of the edges of the flexible flooring h=0.25 m. The production test established the consistency of the proposed new technology of machine harvesting of cabbage and the possibility of reducing the damage to the heads to a level not exceeding 5-7% of the total mass of products.

Published: December 2020

Abstract
The use of waste-free production in the food industry is an urgent problem for the entire world economy. Processing companies most frequently face challenges in managing their waste. This is one of the reasons for low return on production. An example of that is (curd) whey. When making dry-curd cottage cheese and cheese, many dairy plants often do not use whey for further processing, but dispose of it. Therefore, produced in the conditions of the educational and research lab of milk and dairy technology and the educational scientific-production lab of baking, biotechnology and agronomy faculty of the Federal State Budgetary Educational Institution of Higher Education Chuvash State Agricultural Academy, this publication explores the use of whey in baking and its influence on biotechnological processes when baking wheatrye bread. Test lab baking with added whey was successful in terms of organoleptic and physical-chemical properties. Found that in the first experimental group the acidity of the crumb of bread is equal to 9.50 degrees, in the second experimental group 9.02 degrees. The porosity in the second experimental group is 10% higher than in the first group. The moisture content of the crumb in the first experimental group is 2% higher than in the first experimental group.

Abstract
A method of heat localization in the resting area of piglets is proposed. It has been established that the combined use of brooder and radiation or contact heating makes it possible to provide a temperature of 30.0 ± 0.17 … 30.4 ± 0.26 °C for the up to three-weeks-old aged young stock, and 26.6 ± 0.26 … 26.5 ± 0.27 °C without heating means for the seven-week-old aged animals, a reduction of air velocity by 40-50%. The installation of brooders for weaners at rearing allows creating a temperature of 23.4 ± 0.32 … 26.2 ± 0.28 °C, reducing its speed by 26.7…35.7% (P≤0.001) in comparison with the control. The use of brooders for heating contributes (P≤0.001) to an increase in the growth of live weight of young animals by the end of growing period by 8.6…9.6%, the livability – by 2…3%, and the improvement of hematopoiesis, in comparison with radiation heating by infrared lamps.

Published: December 2020

Abstract
Finding the cheaper alternative fuels and shortening the rendang cooking time are the potential efforts to reduce the production cost of rendang. This study aims to use low-rank cheap coal to cook beef rendang and to develop a more efficient rendang cooking method. First, the raw coals were carbonized, then the charcoals obtained were crushed and mixed with the filler and binder. After that, the charcoal mixture was molded into briquettes. Furthermore, the carbonized coal briquettes resulted were characterized and used as fuel to cook beef rendang in a semi-closed moveable-grate stove. To get a more efficient cooking time, a modified cooking method was developed. From the research has been obtained that there was almost no significant odor and smoke emissions during the cooking process except at the initial ignition period, which takes between 10-15 minutes. The modified cooking method took time 3 hours to get the dry beef rendang, 1 hour shorter than that of the normal cooking ones. Briquettes consumption for 1 kg of beef rendang cooking, using the modified cooking method, was about 0.75 kg, equivalent to USD 0.18 if 1 kg of briquette is priced USD 0.24. Finally, it can be summarized that carbonized coal briquette is a solid smokeless fuel that is safe and cheap to cook beef rendang.

Published: December 2020

Abstract
Low-density geopolymer(LDG) mortars have been synthesized through the use of an inexpensive car-wash foaming agent. LDG mortarswere made by mixing coal fly ash and sand with activator solution of NaOH and Na2SiO3. The slurry mixture was then mixed with a thick foam and stirred using a hand mixer. During the stirring process, the ordinary Portland cement (OPC)was added to the mixture as additive. Once homogeneous, the slurry mixture was then poured into mortar molds and left overnight at room temperature before heat treatment at 60 °C for 24 h. The geopolymer mortars formed were then characterized. The density measurement showed that the density of geopolymerdecreased to about half from the original density at the OPC compositions of 5-15% and the activator solution compositions of 20-26%. In this composition range, the highest compressive strength (2.15 MPa) was shown by the LDG synthesized using a 23% activator solution and 15% OPC. Further addition of activator solution decreased the compressive strength due to the increase of porosity. The thermal durability test indicated that the LDG structure was relatively stable up to a temperature of 300 C. A further increase in temperature would cause structural degradation.

Abstract
Indonesia has a large amount of rainfall and can be used as raw water of drinking water. A Radio frequencyplasma system radiation can produce active compounds (•OH-, •O, •H+, H2O2, O3 etc) in water, the active compounds have a high oxidation potential and can kill microorganisms present in water (fecal coliform, total coliform and Salmonella). Plasma system is one way to produce drinking water in terms of health aspects because in the process the tool does not contact with the material directly, so the possibility of contamination is small. The purpose of this study is to remove microorganisms in rainwater using plasma radio frequency system continuously. Samples will be filtered using pure and mix polypropylene cartridge filter with a pore size of 1 μm and then contact in plasma system. Plasma is generated by applying a frequency of 0,16 MHz through a glass reactor with a thickness of 2 mm which is wrapped by a 1 mm copper wire. The results show that the removal microorganism in rainwater using plasma coupled with filtration using pure polypropylene filter reached 100% for total coliform, fecal coliform and Salmonella. While the removal microorganisms in rainwater using plasma coupled with filtration using mix polypropylene reached 70–100%, 85–100% and 80–100%, for total coliform, fecal coliform and Salmonella, respectively.

Abstract
A four-bar mechanism is used in most mechanical equipment to achieve the process or movement. Such mechanisms consist of linksthat move relative to one another. To identify kinematics analysis of a mechanism such as displacement and angular velocity of a four-bar mechanism in one positiongraphically. The analysis conducted throughout the four-bar rotating in 3600 will take a lot of time. For such cases, a computer-assisted analytical is the right way of settlement. The analyses were performed using the Matrix Laboratory software, and establish a four-bar mechanism as a case of study research. Controller PID (Proportional Integral Derivative) is one type of regulator that is widely used, the characteristics of each P, I, and D controllers as well as how to use it to get the desired response. The analysis was made on the variation of rotation and crank length, while the dimension of the link and follower circuit is considered permanent. Comparison of angular velocity for varying stem lengths can conclude that if there is a change in input bar length, it will affect the angular velocity. The greater the length of the input link and so that the angular velocity would be getting lower.

Published: December 2020

Abstract
The earth has an ocean area larger than the land area so that there are many beaches found throughout the world, including Indonesia. Behind its beauty, there is one phenomenon that endangers tourists when doing activities on the near shore area, namely: rip current. For example, the incident at the research location, namely Klayar Beach, East Java, on January 2, 2015, claimed lives. Therefore, this study aims to validate the existence of rip current in East Java, especially at the research location by utilizing hydrodynamic modeling in the era of the industrial revolution 4.0 based on data, internet, and technology as well as human resources during this corona pandemic. There are 3 stages of the methodology in this research, namely data collection and processing, modeling, and modeling validation. The outcomes of this research prove that the phenomenon of rip current with rip current speeds occurs in the range 0.16 - 0.18 m/s which causes 2 tourists to die. It is hoped that the results of this research can be used as input for the stakeholder concerned for the development of coastal tourism in coastal areas on the south coast of East Java in making policies.
Design and analysis of suspended core channel waveguide made using As2Se3 glass system for mid-infrared supercontinuum generation

Published: December 2020

Abstract
In this study, we propose a promising 5 mm long air-clad suspended core channel waveguide made of As2Se3 chalcogenide glass for ultra-broadband supercontinuum generation (SCG) in the mid-infrared (MIR). The linear analysis of the proposed waveguide is carried out numerically by considering the potential application of pump sources at three different wavelength regions such as 1.55, 2.8, and 3.5 µm. Among several waveguide geometries analyzed, numerical simulation for SCG at the output of an optimized structure shows that a flat supercontinuum coverage from 1.5 to 15 µm can be predicted using a pump at 3.5 µm with a moderate peak power of 2000 W. To the best of the authors’ knowledge, this would be the broadest spectra in the MIR by the suspended planar waveguide design. In addition, waveguide structural imperfection has also been discussed as it is difficult to control the waveguide dimensions during the fabrication process precisely. The effect of possible deviations along the transverse dimensions is rigorously analyzed and an imperfection among the several deviations is found which could lead to a substantial supercontinuum bandwidth reduction at the waveguide output. Finally, the degree of coherence of the obtained supercontinuum coverage is also tested and it has been achieved nearly coherent spectral outcome from the proposed suspended waveguide design.
Coupled localized surface plasmon resonances in periodic arrays of gold nanowires on ion-exchange waveguide technology

Published: December 2020

Abstract
Coupled localized surface plasmon resonances (LSPRs) in periodic arrays of metallic nanowires are attractive for use in sensing applications due to their light enhancement and their sensitivity to the surrounding environment. Due to the interwire coupling, they behave as plasmonic waveguides with high wavevector modes that require bulky methods for efficient excitation. In this contribution, we demonstrate the excitation of coupled LSPRs in gold nanowires with photonic modes supported by an optical waveguide made with ion exchange technology. Currently, although weakly-coupled LSPRs are experimentally demonstrated, strongly-coupled LSPRs are only demonstrated numerically due to the challenge represented by the fabrication of a high density nanowire array with current electron beam lithography. Due to their operation across the visible spectrum and its low-loss coupling to standard optical fibers, integrated nanowires on glass waveguides open new perspectives for the development of hybrid photonic-plasmonic integrated optical devices.
Long-distance heat transfer between molecular systems through a hybrid plasmonic-photonic nanoresonator

Published: December 2020

Abstract
We theoretically study a hybrid plasmonic-photonic cavity setup that can be used to induce and control long-distance heat transfer between molecular systems through optomechanical interactions. The structure we propose consists of two separated plasmonic nanoantennas coupled to a dielectric cavity. The hybrid modes of this resonator can combine the large optomechanical coupling of the sub-wavelength plasmonic modes with the large quality factor and delocalized character of the cavity mode that extends over a large distance (∼µm). We show that this can lead to effective long-range heat transport between molecular vibrations that can be actively controlled through an external driving laser.

Published: December 2020

Abstract
Cellulose-based magnetic nanocomposites (Cf-MNCs) have been introduced using a modified one-pot in situ co-precipitation method using iron salts with various concentrations in the alkali solution. Fabricated nanocomposites investigated for structural and functional properties with different spectroscopic characterization techniques prior to use in dye degradation study. The scanning electron microscopy revealed the morphological structure of the synthesized nanofibers and nanocomposites. The elemental analysis and vibrating sample magnetometry emphasized the presence of Fe elements attributed to the iron salts. The HRTEM analysis showed a destructed cellulose fiber network indicating its arrangement into nanocomposites. Moreover, the crystal properties of the Cf-MNCs were accomplished using x-ray powder diffraction (79.3% crystallinity). The Fourier transform infrared analysis and differential scanning calorimetry gives the idea about the structural and functional changes in the cellulose fibers loaded with iron oxide nanoparticles. The functional adsorption properties of the prepared nanocomposites have been evaluated using methylene blue and Alizarin red S carcinogenic dyes. The dye adsorption of the fabricated Cf-MNCs nanocomposites was found to be 93%. We affirmed that this novel eco-friendly degradable polymer-based nanocomposite has great potential in the field of catalyst fabrication for the degradation of organic pollutants in wastewater.
