Authors: Ekasari Christyanita P , Widyarti Sri
Published: December 2019

The coconut water is a healthy beverage that can be used as a solvent in which a heating process can increase the solubility of the solution The nature of coconut water easily changes in the open air. Therefore, a natural coconut water is processed into packaging coconut water. But, the packaging coconut water often contains many additional ingredients which can change the taste and nutrition of coconut water. The aim of this research was to compare the physicochemical properties between a natural coconut water (NCW) and packaging coconut water (PCW). The samples consisted of 4 groups: (1) unheating-NCW (uh-NCW), (2) heating-NCW (h-NCW), (3) unheating-PCW (uh-PCW), and (4) heating-PCW (h-PCW). The physicochemical properties were analyzed based on the UV-Vis spectrum λ 190-790 nm, pH, turbidity, and conductivity. The NCW and PCW respectively had specific wavelengths at 229, 262 nm and 286, 296 nm. PCW had a more absorbancy than an NCW. Heating did not affect the physicochemical properties of an NCW as well as PCW. PCW had higher turbidity than NCW. The high absorbancy and turbidity in PCW were caused by the additional ingredients. All samples had pH which ranges from 5, 42 -5, 49, turbidity 19, 48 – 69, 63 NTU, and conductivity 15, 48 -19, 88 mS.

Published: December 2019

The dominant indigenous microbes, such as lactic acid bacteria group, mainly determine the quality of naturally fermented milk products. Yeasts have also contributed to the fermentation development, especially in determining the organoleptic or physicochemical characteristics of the products. This study was aimed to evaluate the diversity of yeasts in the naturally fermented milk products from Indonesia, which were dadih and dangke by using PCR-RFLP of ITS region. Two dadih samples used with one sample were collected in three consecutive days. Dangke samples consisted of three made from buffalo milk (sample A-C), and sample D was from cow’s milk. The isolated yeasts were further characterized genotypically using RFLP analysis of the ITS region. The representative isolates of each cluster as a result of the restriction pattern obtained with HinfI and HaeIII enzymes were further identified. A total of 37 yeast isolates (17 isolates from dadih and 22 isolates from dangke) were grouped into three clusters based on the band pattern of RFLP analysis. Based on DNA sequencing analysis, the three species were identified as Saccharomyces cerevisiae (group I), Candida metapsilosis (group II) and Kluyveromyces marxianus (group III). Saccharomyces cerevisiae and Kluyveromyces marxianus were found in both dadih and dangke samples. Unfortunately, yeasts were not detected in dangke samples A and C. Candida metapsilosis was found frequently in dadih, while Saccharomyces cerevisiae was the dominant species in dangke. Further investigations are needed to shed light on microbial dynamics since the changes in the abundance and type of microbiota during the fermentation process play a pivotal role in the quality of the final products.

Published: December 2019

Chicken feathers waste are an abundant source of keratin protein. However, keratin contained in chicken feather waste is difficult to degrade so that its utilization becomes limited. Environmentally friendly degradation efforts require keratin proteases in addition to common proteases. Therefore, microorganisms that effectively degrade keratin are needed to recycle the waste. This study aims to isolate and screen fungi that was capable of degrading chicken feather keratin. Isolate with the highest degradation activity index for hydrolyzing chicken feather flour and common protein substrate was selected as an agent for chicken feather keratin biodegradation. The identification was carried out phenotypically and molecularly with phylogenetic analysis of the region gene sequences. The results of the study found Talaromyces sayulitensis GF11 as a candidate for chicken feather keratin biodegradation agent. It is a new strain of keratinolytic fungi which was first published.

Defense against pathogens is essential for survival and it is controlled by innate and adaptive immunity. Phagocytosis is a complex mechanism that involved the activation of macrophages and its cytokines, stimulated T cells, then activation of B cells. Moringa oleifera plants are thought to have immunostimulatory properties due to its complex nutrients and phenolic acids and flavonoids contents as phytochemicals. Lactobacillus plantarum is able to produce lactic acid as the final product to reform carbohydrates, hydrogen peroxide, and bacteriocin as antimicrobial substances, which lead to inhibit pathogenic bacteria. This experiment aims to evaluate the CD11b+ and B220+ population after Salmonella typhi infection with/without administration of M.oleifera leaves extract. Salmonella typhi was labeled with carboxyfluorescein succinimidyl ester (CFSE) to determine phagocytosis activity. This experiment used was a complete randomized factorial pattern design. Mice were divided into two groups, namely the without treatment group and treatment group mice (fermented red M. oleifera leaves extract dose 84 mg/kg BW) and infected by Salmonella typhi. Data analysis was confirmed with the one-way ANOVA test followed by Tukey test (p<0.05). The results showed that fermented red M. oleifera leaves extract can increase the number of CD11b+and B220+ cells at the time of 2 hours and 4 hours.

Published: December 2019

Rice farming modernizations, especially changes in the irrigation system, have been accused as one of the reasons of frog population decline in Japan. Here, we examined responses of native frog, Daruma pond frog (Pelophylax porosus porosus) and non-native frog, Rice frog (Fejervarya kawamurai) population to the modernization in Japanese paddy field. We tested the following two hypotheses: 1) native frog’s density will be lower in the modernized paddy field, and 2) non-native frog density will not be affected by modernization. After two periods of field studies (2017 and 2018), we found that native frog’s density is indeed lower in modernized paddy fields, and the non-native frog’s density is lower in the non-modernized sites. Presumably, changes of shallow soil ditches to concrete ditches in modernized paddy fields act as a death trap for Daruma pond frog. Ditch depth and the distance from forest also significantly affecting the density of Daruma pond frog. On the other hand, the population of Rice frog did not show any negative response to the modernizations. The non-native frog population remained stable because they may have high fecundity.

Published: December 2019

Eggs are livestock products that make the most significant contribution to achieving adequate community nutrition, especially protein. The egg will experience changes when heated. A fundamental change occurs in proteins, namely protein denaturation. The dielectric properties of eggs assessed by measuring capacitance by parallel plate capacitor method. The capacitor plate is 20 x 10 mm2 with a distance between 5 mm plates. Parallel plate capacitors are connected in series with the capacitance probe and inductance on the LCR meter GW-instek 816 series and are measured in the frequency range 100-2000 Hz at intervals of 25 Hz. Samples of race chicken eggs are heated with water for 10 minutes, 15 minutes, 20 minutes, and 30 minutes. The results showed that the capacitance and dielectric constant of egg yolk and egg white of chicken (Gallus Domesticus) changes due to heating. This change indicates the presence of protein denaturation and phase changes in fluid in egg white and egg yolk. The dominance of the liquid in the egg white results in changes in a dielectric constant that are greater due to heating compared to changes that occur in the yolk.

Published: December 2019

Spermonde Archipelago, Makassar South Sulawesi consists of hundreds of small islands with varied land uses and human activities. This will have an impact on decreasing the quality of coastal waters. The purpose of this study was to analyze the relationship between land use and human activities with water quality on the coast around the island. The study was carried out on five islands in the Makassar Spermonde Archipelago of South Sulawesi (Barrangcaddi, Badi, Baranglompo, Bonebatang and Kodingarengkeke Island). Water quality was measured included pH, DO, salinity, turbidity, BOD, nitrate, TP, H2S, oil and grease, and Pb. The coastal water quality observation of each island was carried out in 1-3 stations depending on the size of the island. Repetition of water quality measurements for each station 3 times. Observation of land use and human activities in the study area using the environmental services indices (Hemeroby and Naturalness). The results showed pH (7.99-8.39), turbidity (0.6-1.3 NTU), total phosphate (<0.010 mg/L), H2S (<0.01 mg/L), oil and fat (<0.1 mg/L), and Pb (<0.005 mg/L) still met quality standards of sea water based on Decree of the State Minister for Environment No. 51/2004 for marine biota. DO Levels of Baranglompo and Badi islands (6.1-7.7 mg / L) have met seawater quality standards for marine biota which require DO levels to be more than 5 mg/L. DO levels of water on the other coast of the island 4.6-4.9 mg / L. Water salinity in all water have range 29-30%o. BOD levels (25.4-29.8 mg / L) and nitrate (0.03-0.17 mg / L) have exceeded sea water quality standards for marine biota (20 mg / L for BOD and 0.008 mg / L for nitrates). Baranglompo Island with the highest land use and human activities (Hemeroby 5 and Naturalness 3) has had an impact on water quality degradation reflected in the high turbidity and BOD levels. Bonebatang and Badi islands which have the lowest human activity and land use (Index of Hemeroby 3 and Naturalness 5) have better water quality with low to moderate BOD and turbidity. In order to improve water quality on the coast, human activities on five islands need to be controlled.

Automatic rigidity adjuster sustaining tillage depth during the work of cultivators with elastic rods
Authors: Kokoshin Sergey , Tashlanov Vladislav
Published: December 2019

This paper presents the benefits and disadvantages of the elastic cultivator rags usage. The analysis of the bending moment alongside the rod was made. Shear and moment diagrams were designed to describe the horizontal and vertical forces applying on the cultivator foot. While the resistive force is increasing, the tillage depth is decreasing as a result of a rack deformation. The analyzes of scientific papers on tillage depth stabilizing shows that Euler’s equation is the basis for the subsequent calculations. However, this equation defines the sustainability of longitudinally bend compressed rods in mechanics. Thus, the Euler’s equation has limitations and could not be used in full to solve the deformation problem. While studying curved rods movement using Mohr’s integral, the optimal position of the rigidity adjuster was found. The minimizing of the foot instability and excess movement could be done by the change of the rod length and decrease of the bending moment. In order to maintain the constant tillage depth, the rigidity adjuster was installed. The flexible tubes were used as a controller. The change in hydraulic pressure causes the shift of the impact forces applied on the rod and, as a result, the total bending moment decreases. The described above transformations make the method quite comprehensive. The analysis of the force impact deviation depending on the adjuster position is shown in the paper. That evaluations were used in further calculations, and the optimal position of the rigidity controller on the rod was found. The preliminary assessment allowed to conclude that the evenness of the tillage depth depends on the hydraulic pressure and resistive soil force could be compensated.
Emissivity of the floor surface of the heating zone for weaned piglets
Authors: Popov Vitaliy , Afonkina Valentina , Epishkov Egor , Zagidulin Ruslan
Published: December 2019

To calculate the comfort thermal environment for the weaned piglets, few factors and parameters should be taken into account. This paper is aimed to the experimental calculation of the emissivity (level of blackness) of the floor surface of the heating zone. The emissivity, through the Fresnel law, is closely related to the dielectric constant of a given medium. This parameter is determined by comparing the capacitance of a flat air condenser and a capacitor of the same size filled with the medium under study. The capacitance of a capacitor is determined during the study of the dependence of the phase angle between the input voltage and current on the active resistance of the circuit containing this capacitor. The resulting relationship is analyzed by the method of least squares. As a result, the average value of the dielectric constant and emissivity were calculated. However, a significant drawback of this method is that the medium under study has a significant heterogeneity. In addition, its parameters may depend on temperature and humidity. Further studies are devoted to establishing these dependencies.

Abstracts. The demand for more sustainable agriculture promotes the need for friction parts and components with a high durability and better performance. Widely known that absence of the constant and smooth lubricant supply into the working system is the main cause of the decline in reliability. As a result, most of the time the machines work in conditions of a lubricant deficiency. Thus, the development and implementation of the direct adaptive control methods into the friction nodes could be of great importance. Moreover, this approach increases reliability and simplifies the industrial application of the similar systems.

Modern trends in the availability of information and the widespread use of information and communication technologies not only in everyday life, but also in industry, make it clear that society is on the threshold of a fourth industrial revolution. Such terms as Information Society, Internet of Things, and Digital Economy are understood today as the main focus of state development on which the competitiveness of the national economy depends. The digital economy is primarily defined as a system of economic, social and cultural relations based on the use of digital information and communication technologies. The aim of the presented work is to develop the concept of the Industrial Internet of Things (IIoT) based on an experiment conducted at Murmansk State Technical University. The concept of the Internet of Things was implemented using a small-sized drying unit designed for carrying out the processes of drying and smoking fish and fish products. The proposed method of dewatering reduces the cost of electricity in the production of dried products, extends the life of smoking and drying facilities at the expense of more efficient use of coolant, and improves product quality by reducing the effects of deformation in fish tissues as a result of relaxation.

Published: December 2019

The aim of the study is to develop an expert indicator that allows quantifying the environmental properties of knowledge-intensive machine-building products and considering on its basis the environmental aspects of the use of innovative agricultural machinery, taking into account world experience. The methodology provides for the quantification of each of the alternatives according to expert tables showing different levels of environmental impact of the production, use and disposal of the products. On the basis of the developed indicator, a comparative assessment of the competitiveness of 22 domestic and foreign self-propelled sprayers used in the Siberian region was carried out. Market leaders have been identified. The International Eco-Efficiency Index for 12 producing countries of selected sprayers has been investigated. A correlation-regression analysis of the environmental indicator was performed, which showed a rather high correlation of its values with the rank of the producing country at the specified index. The indicator of competitiveness of selected sprayers according to the set of technical characteristics is calculated. The correlation of the indicator “level of environmental impact” with the technical characteristics of the product was found to be less than EPI. The developed indicator and its analysis methodology are recommended for all types of innovative machine-building products at all stages of the life cycle.

Authors: Berezhnov Nikolay
Published: December 2019

The studies were carried out to determine the compliance of traction-speed performance of the tractor as part of the machine-tractor unit with aggregation requirements, taking into account the random nature of changes in external factors. The work was carried out using the example of the assembly Fendt 936 Vario + AVA-12.6 “Agropitatel” in Leninsk-Kuznetsk district of Kemerovo region in 2017. Using the control dynamometer method, the probabilistic characteristics of the traction resistance of the machine, its dependence on the speed of movement in the operations of the main tillage and intra-soil liquid fertilizer application were determined. The studies were carried out on medium humus on stubble background with depth of soil treatment and fertilizing of 21 cm and the average length of run 1100 m. The tractor Fendt 936 Vario does not ensure compliance with the requirements for operating speed and slipping of propellers when working within the range of average specific drag. Power equipment with the estimated parameters will improve the traction coefficient of performance for 4.7…13.6% in comparison with the tractor Fendt 936 Vario, which will increase the average working traction on the hook, which is implemented without violation of the established requirements. The result will be an increase in the average operating speeds of the unit and an increase of its net hourly productivity.

Energy saving at any enterprise is an urgent problem associated with high expences for energy carriers and a constant increase in their cost. The aim of the study is to modernize the energy system of one of the poultry factories in the Vologda Oblast in Russia in order to reduce electricity costs. Modeling methods for a comprehensive assessment of possible options were usedas well as an experiment that showed that the most effective way to reduce electricity costs was to upgrade the energy system based on “small generation” using traditional fuels. The modernization allowed the poultry farm to produce up to a third of its own electricity with the help of mini-CHPs annually, and to keep the cost of the generated kW⋅h three times lower than the network. The experience of modernization of the energy system of a poultry farm in Russia has confirmed the possibility of joint use of PTL-6(10) and a steam turbine generator at the enterprise. The paper will be useful to researchers and energy specialists who are looking for ways to save energy on a poultry farms.
