Published: March 2022

Abstract
As an important part of the coal mine transportation system, coal mine underground rail transportation undertakes the core transportation task of coal mine underground. Its safe and efficient operation is directly related to the efficiency of coal mine production and transportation. In view of this, this paper proposes a mine track environmental obstacle detection system which integrates camera and Lidar information to realize real-time automatic detection of obstacles in front of the underground track mine cart. The specific research results are as follows: first of all, a point cloud clustering algorithm for the mine environment is designed to extract the obstacle information, and then the YOLOv5 algorithm is used to identify the obstacle information in the image. Finally obstacle information from image and point cloud are fused at the decision-level. The obstacle detection method proposed in this paper can be successfully identified to meet the requirements of the obstacle object detection function of the rail vehicle.

Authors: Huo Chao , Wang Yutuo , Mu Di 
Published: March 2022

Abstract
Due to the large scale, large number of equipment and complex structure of distribution network, relying on manual maintenance of distribution network topology model has a huge workload and poor intuitiveness of model information, which is difficult to ensure the integrity and correctness of distribution network topology model. This paper presents an algorithm to improve the adaptability of multi scene feature signal recognition based on the smart switch core board, and designs the local communication interaction flow design based on topology recognition function from the station area intelligent terminal to the smart switch. The identification technology combining power frequency distortion and characteristic current is adopted. In the identification process, there is no need for the master station to participate in analysis and control. Multiple stations in the same community can be carried out concurrently to automatically identify the connection relationship between distribution network equipment and line topology, and dynamically build a clear and complete household transformer relationship and distribution network topology to help operation inspection, marketing The lean management level of distribution network such as regulation and control has been improved.

Abstract
We propose a three-dimension imaging construction scheme based on Moire fringe and investigate the influencing factors for the fringe generation. Specifically, the principle of the Moire fringe is introduced and a corresponding proof-of-principle experiment is designed and accrued out accompanying with corresponding programming codes subsequently. Four-step phase-shift method and Fourier transform are applied in the experiment to obtain the phase information. Afterwards, the Fourier transformation is added up to a model that shows the surface of the object in terms of the unwrap the phase package. According to the results, the ability of Moire fringe to image is confirmed, which pave a path for various applications, e.g., medical treatment and cryptology.

Abstract
Single Event Effects (SEEs) — predominately bit-flips in
electronics caused by particle interactions - are a major concern
for ASICs operated in high radiation environments such as ABCStar
ASICs, which are designed to be used in the future ATLAS ITk strip
tracker. The chip design is therefore optimised to protect it from
SEEs by implementing triplication techniques such as Triple Modular
Redundancy (TMR).

In order to verify the radiation protection mechanisms of the chip
design, the cross-section for Single Event Upsets (SEUs), a
particular class of SEEs, is measured by exposing the chip to
high-intensity particle beams while monitoring it for observed SEUs.

This study presents the setup, the performed measurements, and the
results from SEU tests performed using the latest version of the
ABCStar ASIC (ABCStar V1) using a 480 MeV proton beam.

Published: March 2022

Abstract
The detection of pulsar signals is a highly intensive
task. Numerous artificial intelligence (AI) and machine learning
techniques (ML) have been proposed to classify pulsar and non-pulsar
signals. While existing machine learning techniques improve
classification efficiency, these methods are limited when it comes
to dealing with large volumes of astronomical data, the extreme
problem of class imbalance , and the polarization of high recall and
precision. In this paper, to accurately classify pulsar and
non-pulsar signals, extreme Gradient Boosting (XgBoost), and Light
Gradient Boosting Machine (LightGBM) algorithms based on an
asymmetric undersampling method are proposed. Firstly, the proposed
model uses an asymmetric undersampling technique that divides the
benchmark datasets into 75 subsets for the LOFAR Tied-Array All-Sky
Survey (LOTAAS-1) and 9 subsets for the High Time Resolution
Universe Pulsar Survey (HTRU2), eluding the class imbalance
problem. Finally, XgBoost and LightGBM algorithms have been adopted
for each new data subset, with a majority voting classifier being
used to integrate the output of proposed models against each
subset. Results of the proposed method were compared to
state-of-the-art baseline models, which showed that our models
significantly performed better than existing methods and gained
almost 2% and 2.5% better F-score and precision results,
respectively.

Abstract
Paleo-climate proxy records documenting sea-ice extent are important sources of information to assess the time of emergence and magnitude of on-going changes in the Arctic Ocean and better predict future climate and environmental evolution in that region. In this study, a suite of geochemical tracers including total organic carbon (TOC), total nitrogen (TN), carbon/nitrogen ratio (C/N), stable isotope composition of organic carbon and nitrogen (δ
13C, δ
15N), and phytoplankton biomarkers (highly branched isoprenoids (HBIs) and sterols) were measured in a marine sediment core to document the sea-ice variability in the Chukchi Sea since the beginning of the Industrial Era. The downcore profile of the sea-ice proxy HBIs suggests a transition from extensive sea ice in the late 19th century to Marginal Ice Zone (MIZ) in AD 1930–1990s and then moderate sea-ice cover since 1990s. Rising of all HBI abundances between AD 1865–1875 indicate a transient retreat of summer ice edge off the shelf followed by a return to near-perennial sea ice till 1920–1930 as revealed by the absence of HBIs and brassicasterol. Sea ice retreat occurred again in AD 1920–1930 and followed by colder decades in 1940s–1960s before a sustained decline since the 1990s. The downcore profile of C/N, δ
13C of organic matter and sterols indicates a gradual increase of terrigenous inputs accelerating during the most recent decades likely due to enhanced fluvial run-off and sediment transport by sediment-laden sea ice. Concomitantly, increasing δ
15N values suggest limited nutrient utilization due to enhanced stratification of the surface ocean caused by increased freshening. The role of the Arctic oscillation (AO), the Pacific decadal oscillation (PDO) and Atlantic Multidecadal Oscillation (AMO) are discussed to explore potential drivers of the observed sea-ice changes.

Abstract
Soya bean meal often used in feeding livestock has environmental issues yearly. One of the efforts to improve the quality of broilers meat as a functional food is the modification process using ingredients such as linseed consisting of high Omega-3 and capable of enhancing feed quality. Therefore, this research aimed to investigate the effect of replacing soya bean meals with linseed meals on broilers. A total of 200 broilers with 7.44 ± 3.14 g BW were allotted to 5 dietary treatments (unsexed) with 4 replicates each. These dietary treatments were NC (negative control; maize-rice bran-meal based diet), LSM2.5 (Soya bean meal replacement with 2.5% modified LSM), LSM5.0 (Soya bean meal replacement with 5.0% modified LSM), LSM7.5 (soya bean meal replacement with 7.5% modified LSM), and LSM10 (soya bean meal replacement with 10% modified LSM). The result showed no significant difference (p >0.05) in the relative organ weights but the modified LSM had a significant difference (p < 0.05) in the treatment performed w a microwave. Furthermore, carcass quality was reflected in the intestinal quality and digestibility of the broiler. In summary, the increase of linseed meal potential through processing technology had a positive effect on broiler meat.

Published: March 2022

Abstract
Embryo transfer is a reproductive technology that shortens the generation interval between selection steps by producing a high percentage of donor progeny. The success of post­transfer pregnancy determines the success of the embryo transfer, but the implantation rate in Indonesia is not yet optimal; measures must be taken to improve the condition of the acceptor. Therefore, this study was carried out to determine the diameter of the corpus luteum and endometrial thickness from local breed, age, parity status, body condition score (BCS) with its effect on progesterone levels and to determine the standard size of the corpus luteum and endometrium. Furthermore, the selected cows were in normal reproductive status. Therefore, they were rectally cycled, and ultrasound (USG) was used to measure the corpus luteum diameter and the wall thickness of the endometrium wall. In addition, blood samples were taken from 7-day-old cows in the oestrus cycle to determine the level of the hormone progesterone using the ELISA test. Of the 15 beef cattle, 9 are PO cattle, and 6 are crossbred cows. The results showed that endometrial thickness was a factor that had a positive correlation with progesterone levels. The highest level of progesterone in crossbreed cows of 12.9 ng/ml resulted in an endometrial thickness of 9 mm, while the highest level of progesterone in PO cattle with 13.8 ng/ml resulted in an endometrial thickness of 5 mm with the optimal standard of the best progesterone levels for PO beef cattle and crossbreed recipients are cows with endometrial thickness > 6 mm, 5 years old, and parity 2x calf. In conclusion, the reproductive status of the ovaries, corpus luteum, progesterone levels, and endometrial thickness are factors that must be considered in increasing the success rate of embryo transfer.

AbstractThis experiment explores the effect and optimal levels of irradiated Chitosan (IrC) in the diet on lipogenesis and its effect on the blood lipid profile of the Sentul Chickens starter phase. The IrC was generated from shrimp waste chitin, and in addition to being a feed supplement, it has the potential to reduce environmental pollution. Furthermore, Sentul chickens were 100 samples, reared from 0-8 weeks, and the observed variables included triglyceride, cholesterol, and blood Non-Esterified Fatty Acid (NEFA). A completely randomized design (CRD) experimental method was used with four treatments and five replications. The treatments were K0 = basal diet without IrC, K1 = 300 ppm IrC in basal diet, K2 = 350 ppm IrC in basal diet, K3 = 400 ppm IrC in the basal diet. Meanwhile, the samples used for analysis were 40 individuals from the research object based on the average body weight of the population. The results showed that the provision of rations containing IrC (K1) 300 ppm, (K2) 350 ppm, and (K3) 400 ppm had a significant effect (P<0.05) on triglyceride, cholesterol, and NEFA profile in Sentul Chickens blood of the starter phase.

Abstract
The agricultural sector is faced with various obstacles, including environmental damage caused by the excessive use of fertilizers and pesticides. In the industrial revolution 4.0, agricultural sector actors need to adapt to change by implementing organic farming. Therefore, this research aims to determine the factors influencing farmers’ attitudes towards organic rice cultivation. This was conducted in Mojogedang District, as the center of organic rice. Data were collected through interviews and observation and analyzed using multiple regression and qualitative information. The results showed that 51.33% of farmers lacked confidence in the certainty of organic rice prices, 66.67% had access to mass media related to organic farming, 61.33% had accepted organic farming interventions, and 76% had good attitudes towards organic rice cultivation. The attitude of farmers in organic rice cultivation is influenced by belief in price certainty and intervention from various parties, while access to mass media has no effect. In order for farmers to have a good attitude towards organic rice cultivation, intervention from extension workers in the form of education, training, and comparative studies related to organic rice cultivation and marketing is needed.

Abstract
This research aims to examine the effect of exposure to extremely low frequency (ELF) magnetic fields on the processing and quality of fresh milk. Furthermore, an environmentally friendly technology that does not require LPG gas or fuel was generated for handling and processing fresh milk. This research consisted of two treatments, such as the type of milk and storage time, which included 0, 5, and 19 hours. Each treatment combination was replicated three times, and the parameters observed were pH as well as the number of microbes. The result shows that exposure to ELF of 801 μT waves for 90 minutes affects the type of milk and total microbes. In addition, the pH value decreased with increasing storage time, while the total microbial value increased with increasing storage time. The use of ELF waves extends shelf life and has the potential for environmentally friendly processing of fresh milk without the use of LPG and fuel.

Abstract
Leather eco-printing is an eco-friendly dyeing technique performed by transferring colors from plants. Therefore, this study aims to investigate the effect of pH and tanning agents on the quality of sheep leather using eco-printing dyeing method to produce an eco-friendly animal product. A total of 30 sheep crust leather were randomly assigned using a 2 × 5 factorial arrangement, with three replications. The first factor was the leather tanning agent namely vegetable and mineral, while the second was pH of 5, 6, 7, 8, and 9. The plants used in eco-printing were Kenikir (Cosmos caudatus) leaves, Kenikir flowers, Jatropha (Jatropha curcas) leaves, Ganitri (Elaeocarpus ganitrus) leaves, Ferns (Pteridophyta) leaves, Lanang (Oroxylum indicium) leaves and Teak (Tectona grandis) leaves. Color sharpness and fastness data were collected and then analyzed using a two-way analysis of variance followed by Duncan’s Multiple Range Test. The results showed interactions between the tanning method and pH (P = 0.01) on color sharpness, with the highest values produced in mineral leather processed under pH 9. Mineral leather had higher color sharpness and fastness values with P < 0.05 compared to vegetables. Furthermore, the pH significantly affected sharpness (P < 0.01) but had no effect on colorfastness. Based on the results, the combination of mineral tanning with a pH of 9 can be applied for eco-printing to produce the best sheep leather product.

Authors: Sulistyo S , Yanti Y 
Published: March 2022

AbstractBiogas extracted from cattle dung waste not only tackles soil and air pollution but also produces methane, which is used in households as fuel for water heaters, cooking stoves, or cloth dryers. The production of biogas also supports a zero-waste approach, which targets eliminating waste by reducing, reusing, and recycling. Therefore, it is necessary for biogas extracted from cow dung waste to be purified and packaged for more efficient use and easier marketing. This study aims to determine the effects of dolomite and biosludge adsorbent in the purification of biogas. Furthermore, the biogas was extracted at 15, 30, 45, 60, 90, 120, 150, and 180 minutes with 3 repetitions during each time period, and methane gas quality tests were carried out in the Balingtan Laboratory, Jaken, Pati, Central Java, Indonesia. Data obtained were analyzed using the RStudio computer application, and the result reveals that the average values for the production of CH4, CO2, and N2O were 3.8 × 105(80.9%) ppm, 8.9 × 105(19.1%) ppm, and 9.0 × 102ppb (0.0002%) respectively. Therefore, the differences in the dimensions of pipes and extraction time had no significant effect on the amount of CH4, CO2, and N2O gas produced.
