Aktivitas Pengelolaan Wisata Petualangan Canyoning Berbasis Resiko

Canyoning adventure tourism is a form of nature tourism activity that provides extreme and challenging experiences for tourists. However, the high level of risk in this activity requires a comprehensive risk management approach to ensure the safety and comfort of participants. This study aims to analyze risk-based canyoning tourism management activities in the Canyoning & Caving area, Bogor, Indonesia. This study uses a qualitative method with data collection techniques in the form of in-depth interviews with tour managers, canyoning guides, and tourists who have participated in the activity. In addition, direct observations were made of field conditions and facilities provided. The results of the study indicate that the implementation of effective risk management is very important to minimize the potential for accidents and negative impacts on the environment. Some of the main risks identified include unpredictable weather conditions, terrain difficulty, and lack of participant experience. The risk mitigation strategies implemented include intensive training for guides, the use of international standard safety equipment, and the preparation of clear emergency procedures. This study is expected to be a reference for other canyoning tourism managers in developing safe and sustainable adventure tourism in Indonesia.

Remote coaching for supporting the implementation of treatment for depression in primary care in Madhya Pradesh, India: protocol for a cluster randomized controlled trial.

Upwards of ninety percent of individuals living with depression in India do not have access to evidence-based treatments, especially in rural areas. Integrating these treatments into primary care is essential for bridging this care gap. This trial aims to evaluate whether a remote coaching implementation support strategy, referred to as Enhanced Implementation Support, is superior to routine support, referred to as Routine Implementation Support, in supporting the delivery of collaborative depression care in rural primary care centers. Employing a cluster-randomized hybrid type-III implementation trial design, 14 primary care facilities in Sehore district, Madhya Pradesh, will implement a collaborative depression care package based on the WHO's mhGAP program. Facilities will be randomized to either Enhanced Implementation Support or the Routine Implementation Support control condition. Enhanced Implementation Support consists of remote coaching and technical assistance, supplemented with in-person visits, and guided by the Plan-Do-Study-Act implementation cycles. The primary implementation outcome is the proportion of outpatients screened for depression by facility staff, with secondary outcomes including the proportions of outpatients who screen positive for depression, are referred to the medical officer, and initiate treatment. Secondary patient outcomes include proportion of patients who achieve reduction in depression symptom severity at 3-month follow up. Acceptability, feasibility, and fidelity of the depression care package will be assessed through routine observations collected during field visits, facility audits, and qualitative exit interviews with facility staff. Costs of delivering the Enhanced Implementation Support strategy will also be estimated. This trial can inform efforts to integrate depression care in rural primary care facilities in a low-resource setting, and illuminate whether external coaching support is superior relative to existing implementation support for achieving these goals.

Implementation of Analytical Hierarchy Process (AHP) to select the best vendor for bio-efficacy trials (case study: the xyz agrochemical company)

Purpose: The pesticide industry is highly regulated by various regulations and requirements. Getting a distribution permit for a pesticide depends on the results of bio-efficacy trials carried out by institutions outside the company (vendors). These vendors must be selected from a list that has been made by the Ministry of Agriculture. Choosing a vendor is quite a difficult endeavor because not all vendors have the same competencies. Research Methodology: One method to choose a vendor among several vendors based on various criteria hierarchically that meets the requirements is to use the Analytical Hierarchy Process (AHP) method. This thesis presents the results of the trial of the use of the AHP method in the XYZ Agrochemical Company using a qualitative and quantitative approach by collecting primary data through questionnaires and interviews with a team of Research and Development experts from the XYZ Agrochemical Company. Results: The results of the case study at the XYZ Agrochemical Company show the practical application of the AHP model in real-world vendor selection scenarios, providing an overview of the relative significance of each criterion and its impact on the overall decision-making process. Limitations: Secondary data was obtained from government regulations, company reports, and relevant literature to form vendor profiles, organizational capabilities, and pesticide regulations that apply specifically to Indonesia. Contribution: Through the AHP framework, based on the results of the interview, a hierarchical structure of evaluation criteria in selecting vendors was established, including expertise, past performance, laboratory and field facilities, timely delivery, in conducting bio-efficacy trials, and vendor responsiveness in communicating.

Analysis of the application of flow-deflecting technologies in order to increase oil recovery

This article discusses flow-deflecting technologies as a method of increasing oil recovery based on the injection of limited volumes of special reagents into injection wells. This technology allows you to: reduce the permeability of highly permeable layers of the formation; align the well intake along the formation section; create a more uniform displacement front; reduce water breakthroughs to the producing well. Flow-deflecting technologies are used at the final stage of field development or in solving problems related to repair and insulation work. Also in this article, an analysis of the effectiveness of flow-deflecting technologies using various polymers is carried out. The results of experimental and field studies of three new technologies based on the use of a chemical agent, for example, POLY-T-101, hydrophobic emulsions and gel-acid compositions are presented during work on limiting water flows and redistributing the directions of filtration flows in terrigenous carbonate reservoirs at reservoir temperatures from 20 to 1000 C. The issues of the mechanism of action of chemical reagents on productive deposits and prospects for the application of the developed technologies at problematic oil field facilities are considered. The results of field tests are presented.

Monte Carlo intercomparison and benchmark of the neutron streaming in the ramified access maze of the CERN High-energy AcceleRator Mixed field (CHARM) facility at CERN

Experiments of high-energy neutron streaming were performed in the access maze of the CERN High-energy AcceleRator Mixed-field (CHARM) facility where high-intensity proton beams of 24 GeV/c impact on a copper target. The streaming of the secondary neutrons through the various legs of the ramified access maze of the facility was measured using aluminium activation detectors installed at 12 different locations: for the first time, the extended coverage of measurement locations allowed to assess the streaming in more distant areas of the maze. The attenuation profile along the maze measured via the production of 24Na was also used to benchmark results from Monte Carlo calculations performed with FLUKA, PHITS, and GEANT4: over almost the five orders of magnitude of the measured production yield, an agreement within a factor 1.4, 1.7, and 2.5 respectively was found for the three codes.

An Apple a Day Keeps the Gray Mold Away

Most consumers dispose of rotten food without a second thought; however, they also throw away a dynamic group of plant pathogens that can be utilized for inquiry-driven investigations into host/pathogen interactions. Botrytis cinerea is a common necrotrophic fungus that can infect most plants but causes substantial losses to the grape and fresh berry industries. Because most store-bought strawberries eventually succumb to this pathogen (due to the presence of spores from the field or packing facility), they are a dependable source of fungal inoculum to test novel hypotheses about the nature of disease. Across the produce aisle, apples are a diverse, well-characterized, and susceptible host population that enables students to construct individualized experiments about the nature of disease with adequate replication for meaningful analysis. This experimental protocol will outline how to conduct an infection assay with B. cinerea and commercially available apple varieties for students to develop their own experiments, inoculate their own plants, and analyze their own data to answer important questions about how pathogens cause disease.

The relationship between deformation mechanisms and mechanical properties in nanocrystalline Cu/Ag-bilayer alloy

The nanocrystalline metallic bilayer structure can effectively enhance the strength of Cu alloy while maintaining excellent electrical conductivity. Based on the microstructure evolution of Cu/Ag alloy observed by transmission electron microscope (TEM), molecular dynamics (MD) simulations of Cu/Ag alloy with nanocrystalline metallic bilayer structure were established. The mechanical properties and deformation mechanisms of nanocrystalline Cu/Ag-bilayer alloys were investigated at different temperatures. A mixed Hall-Petch (H-P) relationship was observed between the ultimate stress and the increased layer thickness. In this paper, the deformation mechanism changes from dislocation accumulation at the Cu-Ag interface to dislocation through the Cu-Ag interface. In addition, the data analysis results of elastic modulus showed an approximately linear decrease trend with increasing temperature, and the deformation mechanism shifted from dislocation motion to a combination of dislocation motion and grain boundaries (GBs) diffusion. These findings provide guidance for the design of high magnetic field facility (HMFF) water-cooled magnets and very large-scale integration (VLSI) lead frames.

A Managerial Development Model for Promoting Elite Futsal Players at University

Background and Aim: As the sports industry develops and society pursues a healthy lifestyle, sports are becoming increasingly important in higher education. Futsal, due to its relatively low requirements for field facilities, is more suitable for implementation on university campuses. However, despite the high popularity of futsal on university campuses, most universities' futsal training focuses more on popularization and entertainment, without giving enough attention to the improvement of competitive levels. The purpose of this study was to construct a managerial development model for promoting elite futsal players in university. Materials and Methods: This study is a survey type. The population of this research includes Sampling includes 7 expert interviews. 250 elite futsal players and 20 coaches for the questionnaire method for drafting the managerial development model. 19 experts will be selected to construct the development model for elite futsal players by the Delphi consensus method. 9 experts will be used to verify the draft of the managerial development model for elite futsal players. Using questions created by the researcher that are based on the POLC theories. After analyzing the data, the researcher drafted the managerial development model. After that, send the managerial development model to experts for improvement. Complete editing in the Delphi consensus method and final confirmation with the connoisseurship method by experts. Result: After constructing the draft of the managerial development model for developing elite futsal players in the university, it was found that there were 12 planning elements, 11 organization elements, 14 leading elements, and 8 controlling elements, totaling 45 elements. There are two elements with a mean of 4.44 “A policy has been established to promote elite athletes in universities”, and “Relevant personnel is promoted to attend training in various courses to develop the organization's knowledge in preparing a team of elite futsal athletes”, showing that these three elements are highly effective in use. The remaining elements have an average of 4.56 to 4.76, indicating that these elements are very highly effective in their application. Conclusion: In the development of elite futsal athletes, the experts highlighted that many universities lack a clear management service system structure. This deficiency extends to areas such as budget management within the organization, the allocation of personnel appropriate to their roles and responsibilities, and the preparation of equipment and venues. Consequently, the management plan system lacks specificity. The university should clearly adhere to this policy by allocating time effectively to students. One of the key issues is the lack of communication and collaboration among personnel involved in developing futsal athletes within the university. Additionally, balancing the demands of both learning and studying is in alignment with the established educational system.

Assessment of the industrial emissions impact on the quality of atmospheric air in the Burlin district of West Kazakhstan region DEVELOPMENT

The article is devoted to the study of air pollution in the Burlin district of the West Kazakhstan region, where one of the main sources of air pollution is the Karachagan oil and gas condensate field, the main feature of which is the high content of hydrogen sulfide in natural gas from 4 to 4.3%. The analysis showed that the atmospheric air state in the specified area is determined by the characteristics of harmful emissions sources, composition, volumes of pollutant emissions and climatic characteristics of the territory, which determine the conditions for the polluting components dispersion. The qualitative and quantitative characteristics of the chemical composition of the atmospheric air in the study area, as well as the features of their changes over the years end climatic seasons, are largely determined by emissions of nitrogen oxides, carbon, sulfur dioxide, hydrogen sulfide, volatile organic compounds and inorganic dust into the atmosphere by oil and gas facilities. The anthropogenic influence of industry in this area is also evidenced by the calculated value of the integral coefficient of air pollution. At the same time, industrial enterprises, having increased the anthropogenic impact on the environment, have the ability to prevent negative environmental consequences. The system of industrial environmental control of the chemical composition of industrial emissions at the Karachagnak field facilities is carried out on an ongoing basis. The analysis showed that a reduction in emissions and, accordingly, a reduction in ground-level concentrations of air pollutants at the Karachagnak field facilities is ensured by a whole range of technological and organizational measures, among which the technology of high-pressure gas reinjection deserves special attention. It necessitates the need to carry out systematic work to study the ecological state of the territory of the Karachagnak field, using not only ground-based research methods, but also modern geoinformation and aerospace technologies that make it possible to dynamically assess the changes taking place, conduct a geo-ecological assessment and make a forecast for the development of the environmental situation in this area. territories. The work carried out contributes to further analysis of the regional assessment of the environmental state of the atmosphere of large industrial centers.

Analysis of the Influence of Oil Pollution on the Bacterial Component of Groundwater in a Karst Region on the Territory of a Long-term Developed Oil Field

The influence of oil pollution of groundwater in a karst region onto the bacterial component was studied. It has been established that bacteria are present in groundwater in an amount of 103–106 cells/ml. Representatives of the genus Arthobacter, Microbacterium, Rhodococcus, Williamsia (phylum Actinobacteria), Achromobacter and Pseudomonas (phylum Proteobacteria), Bacillus and Brevibacteria (phylum Firmicutes) were revealed. The state of the microbial component of the studied groundwater was analyzed according to the scale of environmental modifications. It was concluded that, with the exception of the release of groundwater at a site 320 m away from the oil field facilities, bacteriocenoses are in a state of "anthropogenic ecological stress".

Ортогональные ветроэнергоустановки для нефтегазопромысловых объектов на суше и на море

Wind and solar power plants for autonomous power supply of small oil and gas facilities with a capacity of no more than 20 kW, wind power plants in their composition – 10 kW with a power factor (energy efficiency) of no more than 0.35–0.45 are considered. An improved design of an orbital wind power plant based on a combined H-Darye-Savonius rotor has been developed. Experiments on the laboratory installation showed that the maximum values of the power factor reached 0.60, which is much higher than that of the rotors of known types of wind turbines. The values of the CRDS power factor are calculated for various geometric dimensions of the N-Darye and Savonius rotors included in its composition. With an increase in wind speed to the nominal value of 9.0 m/s for small and medium power wind turbines and a rotor diameter of 15.0 m, the combined rotor power reaches almost 60 kW. The proposed orthogonal wind power plants with a nominal capacity of up to 60 kW will be able to be used together with other power plants for autonomous power supply at oil and gas field facilities on land and at sea, and in the future at intelligent fields.

Field application of bio-foam spray to reduce ammonia emission from ammonia-rich swine manure piles

In this study, the first field-scale application of a bio-foam spray (a mixture of microbes and a surfactant) for the reduction of ammonia emitted from manure was investigated on six field swine manure piles. The objective of this study was to evaluate the odor suppression ability of bio-foam and odor degradation ability of odor-degrading bacteria loaded in the surfactant foam after covering manure piles. The size of field manure piles tested in this study ranged from 27 to 300 m3. Bio-foam spraying completely suppressed the release of the major odor component, ammonia (NH3), and odor-degrading bacteria in the bio-foam aided in the degradation of NH3 in field swine manure piles. On average, 85.7–100% of NH3 was reduced after 24–48 h of serial bio-foam spray application on the swine manure surface, while the control showed 25–42%. The reduction efficiency of NH3 by the bio-foam application was affected by the bio-foam spray frequency, ambient temperature, ventilation of the field facility, and upward airflow to the pile. The reduction in surface emission of NH3 also reduced the ambient air concentration of NH3 at the gate of the compost facility. NH3 gas measurements at a depth of 50 cm indicated that NH3-degrading bacteria infiltrated the manure and were active in biodegradation. Finally, the measured effectiveness of bio-foam application as shown by this study indicates that sprinkling bio-foam via specialized rotating sprinklers may be an efficient and uniform method for the delivery of bio-foam to wide field areas within composting facilities.

Thermally stable quantum Hall effect in a gated ferroelectric-graphene heterostructure

The quantum Hall effect is widely used for the investigation of fundamental phenomena, ranging from topological phases to composite fermions. In particular, the discovery of a room temperature resistance quantum in graphene is significant for compact resistance standards that can operate above cryogenic temperatures. However, this requires large magnetic fields that are accessible only in a few high magnetic field facilities. Here, we report on the quantum Hall effect in graphene encapsulated by the ferroelectric insulator CuInP2S6. Electrostatic gating of the graphene channel enables the Fermi energy to be tuned so that electrons in the localized states of the insulator are in equilibrium with the current-carrying, delocalized states of graphene. Due to the presence of strongly bound states in this hybrid system, a quantum Hall plateau is observed over a wide range of temperatures in relatively modest magnetic fields.

Status of the High Field Cable Test Facility at Fermilab

Fermi National Accelerator Laboratory (FNAL) and Lawrence Berkeley National Laboratory (LBNL) are building a new High Field Vertical Magnet Test Facility (HFVMTF) for testing superconducting cables in high magnetic field. The background magnetic field of 15 T in the HFVMTF will be produced by a magnet provided by LBNL. The HFVMTF is jointly funded by the US DOE Offices of Science, High Energy Physics (HEP), and Fusion Energy Sciences (FES), and will serve as a superconducting cable test facility in high magnetic fields and a wide range of temperatures for HEP and FES communities. This facility will also be used to test high-field superconducting magnet models and demonstrators, including hybrid magnets, produced by the US Magnet Development Program (MDP). The paper describes the status of the facility, including construction, cryostat designs, top and lambda plates, and systems for powering, and quench protection and monitoring.

Superconducting Magnetic Energy Storage for Pulsed Power Magnet Applications

As part of the exploration of energy efficient and versatile power sources for future pulsed field magnets of the National High Magnetic Field Laboratory-Pulsed Field Facility (NHMFL-PFF) at Los Alamos National Laboratory (LANL), the feasibility of superconducting magnetic energy storage (SMES) for pulsed-field magnets and other pulsed power loads is examined. Basic SMES parameters needed to power one of the coil groups of the large 100 T magnet were determined. A circuit topology for the power transfer between the SMES and the magnet was devised, and the basic performance of the topology was simulated to reproduce the pulse shape currently used in the 100 T magnet. The Finite element analysis (FEA) method was used to calculate the magnetic field distribution of several preferred coil configurations for effective SMES design. Magnetic field distribution and the field dependent critical current density of commercial high temperature superconducting (HTS) tapes were used to understand the conductor/cable requirements for the SMES.
