Abstract
One of the biotechnology reproductive used is estrus synchronization. This study determined the body’s physiological, estradiol level, and ovarian and follicle diameter in Peranakan Ongole (PO) cow estrus synchronization using modified progesterone-PGF2α and double injection of PGF2α. This study used 10 PO cows which were divided into two groups. Group 1, cows were given a modified intravaginal sponge containing 250 mg progesterone/sponge for 6 days, followed by intramuscularly injection of PGF2ɑ 25 mg/cow on day sixth. Appearance of estrus was observed on day 7th -9th. Group 2, cows were given a double injection 25 mg/cow of PGF2ɑ intramuscularly at 14-day intervals, then estrus was observed on day 15th -17th. The vaginal temperature was checked using a thermometer, the respiratory frequency was checked by inspection of thorax movements, and the pulse rate was checked by palpation of the coccygeal artery. Ovarian and Graafian follicle diameters were examined using ultrasonography. The data were analyzed using either T-Test or descriptive test. The results showed that in cows that were synchronized to estrus using combination of modified progesterone-PGF2ɑ and double injection of PGF2ɑ, the vaginal temperature, pulse rate, and respiration frequency were 36.9±0.98 and 37.34±0.83, 57.60±12.52 and 74.80±26.59, 30.40±10.43 and 20.00±2.83 respectively. There was no significant difference in ovarian and follicle diameter (P>0.05). The conclusion was the results of body physiology were in normal conditions but still below the average of cows undergoing estrus, and there were no significant differences in ovarian and Graafian follicle diameters.

Exploitation of powered roof support in variable mining and geological conditions
Authors: Borska Beata 
Published: June 2023

Abstract
The powered roof support is one of the essential elements of the technical equipment of the longwall. It is responsible for the safety of machines and workers. In addition, its function is to move the entire wall complex along the operational progress of the combine. Choosing the proper powered roof support per the conditions prevailing in the wall is an important factor for safe and effective operation. The aim of the study was to assess the mining and geological conditions in Polish hard coal mines in terms of the operation of powered roof support. The author focused mainly on analysing the risk of rock mass shocks, which significantly impact the work of the powered roof support. The work describes the development of the risk of tremors in recent years. The analysis showed an intense increase in this threat. We present an analysis of rock mass shocks registered in Polska Grupa Górnicza S.A. (Polish Mining Group), the main producer of hard coal in Europe. The results presented in this paper illustrate the scale of the risk of rock mass shocks. The current state of the tremor hazard presented in the paper may be helpful information in determining the directions of development and optimisation of the powered roof support.

Published: June 2023

Abstract
Monitoring and diagnostics of elements of the belt conveyor is a challenging task. One of the hardest aspects is dealing with objects such as rolling idlers that support the belt. They are distributed along the entire length of a conveyor, and their amount can easily reach thousands. In the ideal case, every idler should undergo in-situ monitoring, however, this is impractical. Hence, it is proposed to use remote sensing to acquire knowledge about some aspects of their condition. In particular, the authors propose to measure the rotational speed of the idler based on short video recordings. This data could be captured by mobile inspection robots, such as UAVs or UGVs, or even manually. Detecting the fact that the idler rotates with improper speed (lower than nominal), could indicate a developing fault of the internal bearing. An idler that rotates slower than it should also create additional friction between itself and the belt. This friction can increase the overall operational resistances, and even cause fire due to increased temperature. In this paper, the authors present a simple method for establishing the rotational speed of the idler based on video data analysis.
Robust switching Kalman filter for diagnostics of long-term condition monitoring data in the presence of non-Gaussian noise
Authors: Shiri Hamid , Wodecki Jacek , Zimroz Radosław 
Published: June 2023

Abstract
Machinery condition prognosis system uses long-term historical data to predict remaining useful life (RUL). One of the critical steps to reach this purpose is to segment long-term data into two or several degradation stages (Healthy, Unhealthy, and Critic stage). Finding changing points between regimes may be a crucial preliminary task for further predicting the degradation process. However, finding the accurate partition into two or more regimes is a challenging task in the actual application when the noise inherent in the observed process is non-Gaussian. Therefore, this paper introduced a robust methodology based on switching Kalman filters to address the problems mentioned. This approach uses multiple dynamic system models to explain different degradation stages, utilizing robust Bayesian estimation. Also, based on this fact, this approach works based on dynamic behavior; a threshold for diagnostics is no longer needed. Ultimately, the proposed approach is applied for the online diagnosis of simulated data sets in the presence of Gaussian and non-Gaussian noise. The result of the applied methodology on simulated data sets proves the method’s efficacy.

Published: June 2023

Abstract
Underground mining of deposits is strongly dependent on several key processes enabling its safe operation. One of these processes is mine ventilation aimed at supplying an appropriate amount of air with a specific chemical composition, diluting harmful gases generated in technological processes and emitted from the rock mass, and ensuring appropriate climatic conditions at workplaces. For all that mine ventilation has strategic importance and is responsible for 30-40 % of overall mine operation costs. A very important task is to conduct calculations and simulations to determine the airflow in ventilation networks, both existing and planned in the future, along with the progress of the mine operation. In the era of the development of modern technologies, new perspectives for changing the current approach to the design and optimization of ventilation networks are available. Their utilization may contribute to accuracy improvement, which can drive safety increases and process optimization. In this article, the authors evaluate the possibilities of using laser scanning data, collected with LiDAR / Terrestrial Laser Scanner, to generate 3D models of underground structures geometry, and its further utilization to conduct numerical simulations of airflow in mining excavations with Computational Fluid Dynamics. The performed analysis shows that the proposed approach may be a useful instrument for analyzing local airflow phenomena, particularly in complex ventilation networks, where disturbances in air velocity vectors are caused by sudden changes in geometry.

Authors: Maciejewski P 
Published: June 2023

Abstract
According to the hypothesis of radiation hormesis, in appropriate doses, radon may have a positive effect on the human body, but it’s too high concentration becomes harmful. According to the applicable provisions of law, some employers are obliged to measure the concentration of radon activity in the air. The article presents the results of long-term measurements (with CR-39 detectors) and the results of short-term measurements made by the author (using the AlphaGuard device) in a public utility facility - a kindergarten in Bolesławów. It is located in an area with moderate radon potential. The article presents the results for two rooms. In one of them, construction works took place before the measurements, during which the floor was protected with a foil, on which a screed was made. In the second, this procedure is only planned. Based on the results, it was found that the floor insulation can reduce the concentration of radon activity in indoor air even three times. Short-term measurements also showed a significant influence of air exchange on the concentration of radon activity. Thanks to airing the room, the concentration of radon activity can be reduced two or even three times.

Vertical Extension of Soil Moisture Data in Hungarian Soil Types with Different Interpolation Methods
Authors: Deák T , Dobos E , Kovács Z K 
Published: June 2023

Abstract
An important step in today’s modern precision crop production systems is the development of an irrigation system for arable lands. Most of these systems only examine the top, 10 cm layer of the soil. The problem is that the root system of the crops also penetrates and grows into the deeper layers while absorbing water. For this reason, there is a need for a cost-effective solution to quantify the amount of water up to 1 meter depth. Sentek EnviroSCAN sensors were used to measure soil moisture (SM) values of different soil types located in Hungary having different soil mechanical and chemical attributes. SM values were only measured at certain depths. The missing depths are supplemented with estimated data done by interpolation. However, these estimations are not enough, as these sensors were located on different soil types, i.e. one kind of interpolation method may not be suitable to all sensors without significant statistical error.
Several soil moisture sensors were deployed. Each of them is placed on a specific soil type. The measured SM depth values were then used to produce estimated SM values lasting from 10 to 100 cm by using 8 types of interpolation methods. The interpolation was performed using a Python framework called Scipy. The final result of the research is the evaluation of the model performance of the soil moisture data estimated by 8 types of interpolation methods for different soil types in Hungary.
Drought and flood hazards management for agricultural water users in Central Java, Indonesia
Authors: Mawardhi AD , Linga SN 
Published: June 2023

Abstract
Central Java has a huge population and is the food production area for Indonesia. Due to its geographical complexity and the human factor, it is very vulnerable to drought and flood hazards. This study aimed to analyse drought and flood events in Central Java and their impact on economic, environmental, and social aspects, as well as to evaluate the multi-hazard management in Central Java related to agriculture. Drought and flood monitoring were conducted by SPI and SPEI. Those hazard forecasting were done by correlating the selected drought index to MEI. The drought vulnerability of five municipalities in Central Java was evaluated by DVI. Proposed mitigation strategies were offered after evaluating the results and current disaster management. This study showed that SPEI-3 was the best method to determine dry and wet periods in Central Java during 1980-2010, and its correlation to MEI was relatively higher than other indices (R2=0.3612). Karanganyar is the least vulnerable region to drought (DVI=0.36) and Rembang has the highest DVI (0.59). Since numerous stakeholders are responsible for managing water availability for different sectors, then proposed improvements for current agricultural mitigation strategies are focused on government, farmers, public water supplier, and coastal residents and their particular measures.
Analysing regional development in Indonesia based on GDP and cement consumption from 2010 to 2020
Authors: Siringo R , Suwardi E , Haryono E , Kurniawan A 
Published: June 2023

AbstractThis article analyses regional development in Indonesia from 2010-2020, based on its cement consumption. It investigates the relationship between cement demand, GDP, population, and urbanization by using Ordinary Least Square regression. In this period, Java known as the central cement producer and intake most of the product from the market. However, cement consumption per capita (CCP) in Kalimantan was the highest during 2010-2015 and in Sulawesi during 2016-2020. Meanwhile, high distribution cost has caused Eastern Indonesia consumed cement the least. The regression analysis shows that nationally and in four regions, variables GDP and population have positively influence while urbanization has negative influence on the cement demand. This relationship, however, do not exist in Sulawesi and Maluku-Papua. Negative coefficient values of urbanization indicate that road transport infrastructures and public facilities has played a more important role in urban cement consumption rather than public housing. Secondly, we found that GDP per capita (GDPP) positively affect the CCP, unless in Kalimantan region. An increase of 1% GDPP will cause national CCP to raise by 0.005%, regional CCP in Java and Sumatra by 0.005% as well, but in Sulawesi, Bali-Nusa Tenggara, and Maluku-Papua, CCP will raise by 0.01%. The extreme CCP gap portrayed the disproportionate in regional development in the country. Although massive infrastructure projects have lessened the gap, it is necessary to have an adequate supply of the product in each region with affordable price to accelerate regional development.

Published: June 2023

Abstract
The issue of gold mining industry in Trenggalek has increasingly been a high concern among the local people. People are aware that the mining industry will give adverse impact for their life now and the next generation, because of the natural destruction resulted from the extraction industry. People’s concern is expressed through the texts produced by local people to be circulated locally and more widely. The texts analyzed in this study are the articles in the local portal of “Nggalek.co,” which is locally produced by young people in Trenggalek. As the unit of analysis, there are 6 articles, selected by using the keyword of “tambang emas” (gold mining). This study aims at understanding the discursive strategy of the writers (Trenggalek community) in producing the text in building resistance discourse of the gold mining industry for ensuring the local sustainable development. This research is based on Foucauldian critical framework and critical discourse analysis by employing the Fairclough’s framework of three levels of analysis: micro, meso, and macro. The analysis resulted in identifying the discursive strategies in the form of key themes (knowledge produced) through the text, explaining the social political context of the resistance discourse, and identifying the power relations among the actors.
Komering wathersed land conservation under The Marga System
Authors: Istianda Meita , Irwanto Dedi , Giyanto  
Published: June 2023

Abstract
In the 1980s, efforts to integrate regions across Indonesia, especially South Sumatra, led to the elimination of customary law and customary government. Before the introduction of the Undang-Undang Desa (Village Government Law), South Sumatra’s customary government had adopted a customary government system known as the Marga system. This study employs a spatial methodology, combining historical maps and satellite pictures as data sources, to examine the level of deforestation in the Komering watershed from before the Marga government was dissolved till after it was abolished. In addition, the purpose of this study is to determine the function of customary law in preserving environmental sustainability in the Komering watershed. The results of processing the topographic map from 1910 were then compared to the results of processing the Sentinel-2 satellite image to see how the level of the land had changed over a century. The annual average rate of deforestation is around 274,944 ha per year. That is, there have been significant changes in land usage for 109 years. Part of the forest is converted into fields and plantations, while the majority of the swamps and marshes are converted into rice fields. The impetus for this transformation began in 1983, when the Marga government system was abolished. Long in charge of South Sumatra, the Marga Government System has already established regulations for conserving its natural resources. The system is a successful method for managing watersheds because of its pattern of limited land cover on slopes and along rivers. The inhabitants of South Sumatra are ruled by a system of Marga, and their daily lives are guided by the customary law. The Simbur Cahaya Customary Law controls sociopolitical connections between communities. The management of these relationships appears to be an effort to safeguard shared resources, such as forest timber plants and riverbank land. Consequently, customary law plays a vital role in protecting the environment, especially forest land and njurung land (mid-channel bar).

Abstract
Local wisdom cannot be denied being able to maintain the environmental sustainability of indigenous peoples in various dimensions of life. The Samin community is one of the tribes in Indonesia that has a strong traditional spirit. The aim of the study is to describe local wisdom in the agricultural activities of the Samin community in Sambongrejo, Blora, Indonesia. A qualitative approach was developed to obtain a model of local wisdom in the ancestral teachings of the Samin community which are still being maintained. Collecting data in this study employed observation, interviews, documentation, and FGD (Focused Group Discussion) with several Indigenous Samin’s figures. The result shown teachings of Samin’s ancestors taught that life must be in harmony with nature. Therefore, agriculture is performed with the principle of zero waste to minimize environmental impact. The Samin community implements an integrated organic farming system with livestock so that the biological cycle can occur. Plants are cultivated by intercropping method for commodity diversity. Local wisdom that developed according to technological developments even though it is based on the old teachings (ancestors) can still provide maximum benefits for the sustainability of life. The zero-waste principle implemented to the Samin community’s agriculture is a manifestation of environmental ethics from the teachings of the ancestors to produce sustainable agriculture.
