Analysis of Education and Knowledge’s Relationship on Worker Behavior in Waste Processing and Disposal in The Sasirangan Home Industry in Banjarmasin

Sasirangan is a typical cloth from the South Kalimantan which is produced by the Banjarist people in home industries. The production of sasirangan has a very positive impact on the welfare of Banjarist people. However, the processing and liquid waste resulting from the production process can have a negative impact on workers' health and the environment because it contains synthetic dyes and heavy metals. This is caused by poor worker behavior in processing and disposing of liquid waste from sasirangan cloth. Worker behavior can be related to worker education and knowledge. This research aims to analyze the relationship between education, knowledge and the behavior of sasirangan workers in processing and disposing of waste in the home-based sasirangan industry in Banjarmasin. This research is an analytical observational study with a cross sectional approach, carried out at 3 (three) sasirangan production locations: Sungai Jingah, Seberang Masjid Village and Surgi Mufti subdistricts. Sampling used a purposive sampling technique with a sample size of 30 workers. Data analysis was carried out using descriptive and statistical analysis using the Chi Square test with the alternative Fisher Exact Test. The results of data analysis show the p value of the education variables (p=0.032) and knowledge (p=0.049). There is a significant relationship between education and knowledge and worker behavior in processing and disposing of waste in the sasirangan home industry in Banjarmasin. This is in accordance with Lawrence Green's theory, the better the worker's education and knowledge, the better the worker's behavior. The existence of a significant relationship between education and knowledge and workers' behavior in processing and disposing of waste in the sasirangan home industry in Banjarmasin requires follow-up in the form of efforts to increase education and knowledge regarding the processing and disposal of sasirangan waste for workers in the sasirangan home industry in Banjarmasin.

The effect of emotional intelligence, motivation and job burnout on safety behaviors of construction workers: a case study

PurposeGiven the cruciality of construction workers' safe behaviors, the possible influential factors on workers' behaviors should be studied, and one of these factors is characteristics. The authors identified emotional intelligence (EI), motivation and job burnout as characteristics that might affect a worker's safety behavior, and the aim of this study is to investigate these possible relationships.Design/methodology/approachWorkers' EI, motivation and job burnout status were assessed by a structured interview. Furthermore, workers' safety behaviors were assessed by a checklist derived from national codes, regulations and other research studies. Then, the researcher's observations took place, and the data were acquired.FindingsEI and motivation of workers were able to predict safety behaviors, and the effect of job burnout on safety behaviors was not significant. In addition, motivation's influence on job burnout was not significant. Therefore, in order to promote safety behaviors, the EI and motivation of workers need to be taken into consideration.Practical implicationsThe results indicate why construction managers should consider the workers' EI and motivation competencies and how this consideration could lead to safer and better performance in construction projects.Originality/valueThe possible effects of EI, motivation and job burnout on the safety behaviors of construction workers haven't been paid enough attention. Moreover, the authors couldn't find a study similar to the present one that was conducted in Iran. Also, an original model was presented, and safety behaviors were studied through fieldwork rather than using questionnaires.

Glyphosate-based formulation affects Tetragonisca angustula worker's locomotion, behavior and biology.

Declining bee populations diminish pollination services, damaging plant and agricultural biodiversity. One of the causes of this decline is the use of pesticides. Pesticides with glyphosate as the main active ingredient are among the most used pesticides worldwide, being the most used in Brazil. This study determined the 24 and 48 h LD50 (median lethal dose) of the herbicide's glyphosate-based formulation by ingestion, identified sublethal doses, and investigated its effects on the locomotion and behavior of Tetragonisca angustula workers. The LD50 found indicates that a glyphosate-based formulation is highly toxic to T. angustula. The doses applied, including concentrations found in nature, caused death, motor changes (decreased speed and tremors), excessive self-cleaning, and disorientation (return to light and stop). Although we did not test for pollination effects, we can infer from our results that this formulation can negatively affect the pollination activity of T. angustula. Evaluation of the toxicity and sublethal effects of pesticides on bees contributes to a better understanding of their harmful effects on hives and allows for the development of strategies to reduce these impacts.

Analysis of the effect of employee status on construction worker's safety behavior using structural equation model

The construction industry is one of the most at risk to worker safety. The number of work accidents in Indonesia continues to increase so that by 2021 the number of work accidents will reach 234,270 cases. Therefore, in-depth research is needed to maintain the safety of all workers. Recognizing the factors that cause work accidents helps stakeholders take preventive action. It is necessary to increase worker safety behaviour by identifying its factors. Both those that occur in casual workers and permanent workers. Therefore, it is important to see whether employment status affects the safety behaviour of construction workers so that preventive measures can be taken as a form of prevention of work accidents. The research objective was to analyze the status of workers on the safety behaviour of construction workers. Data was collected through a survey method of 300 construction workers in the cities of Surabaya, Malang, and Batu in East Java, Indonesia. The results of the study show that worker status has a positive effect on construction work safety behaviour. This means that the higher the Employee Status will increase the Safety Behavior variable, with a path coefficient of 0.390. Among the indicators that are dominant in measuring the ES Worker Status construct is the Type of Worker, with the highest loading factor of 0.842. Thus, if the management wants to raise the value of the variable Safety Behavior through improving aspects of Employee Status, what need to be evaluated as a top priority is the Employee Type. The results of this study can be used as a reference in setting policies related to worker safety. Project management can determine what strategic steps need to be taken for construction workers with different types of employee statuses. so as to increase worker awareness of a culture of safety behavior.

Evaluasi Pencegahan dan Penanggulangan COVID-19 Pada Industri Petrokimia di Sumatera Selatan

The COVID-19 pandemic has a global impact, not only on health but also on the economic sector. In order to support the sustainability of the economy, various industries continue to carry out business activities during the COVID-19 pandemic. To support this situation, various parties, both government and international institutions such as the International Labour Organization (ILO) have developed guidelines for preventing and controlling COVID-19 in the workplace. Further evaluation of the implementation of these guidelines is very important to determine the company's level of readiness in dealing with the COVID-19 pandemic. This study was conducted at PT X, one of the Petrochemical Companies in South Sumatra. This study was conducted in September 2021 – January 2022. This is a semi-quantitative study with a Cross Sectional design. Data were collected through direct observation and review of company documents based on Kepmenkes No. HK.01.07/Menkes/328/2020, SE Minister of Manpower No. M/7/AS.02.02/V/2020 and the 2020 ILO guidelines. Data triangulation was carried out by in-depth interviews with 7 key informants. The results showed that PT X has implemented the COVID-19 prevention and control programs with a readiness level of 91.3%. However, there are programs that have not been implemented (the prevention of stigma and discrimination, evaluation of worker's knowledge and behavior, and also the structure of the COVID-19 team has not been included in the P2K3 structure. It is recommended to PT X to implement these programs in order to optimize the efforts that have been made.

A role of anterior cingulate cortex in the emergence of worker–parasite relationship

We studied the brain mechanisms underlying action selection in a social dilemma setting in which individuals' effortful gains are unfairly distributed among group members. A stable "worker-parasite" relationship developed when three individually operant-conditioned rats were placed together in a Skinner box equipped with response lever and food dispenser on opposite sides. Specifically, one rat, the "worker," engaged in lever-pressing while the other two "parasitic" rats profited from the worker's effort by crowding the feeder in anticipation of food. Anatomically, c-Fos expression in the anterior cingulate cortex (ACC) was significantly higher in worker rats than in parasite rats. Functionally, ACC inactivation suppressed the worker's lever-press behavior drastically under social, but only mildly under individual, settings. Transcriptionally, GABAA receptor- and potassium channel-related messenger RNA expressions were reliably lower in the worker's, relative to parasite's, ACC. These findings indicate the requirement of ACC activation for the expression of exploitable, effortful behavior, which could be mediated by molecular pathways involving GABAA receptor/potassium channel proteins.

Occupational Stress In Medical Workers at Naibonat Hospital

Abstract: Occupational stress is a condition in which the work demands exceed the workers' capabilities, resulting in various adverse reactions to the worker's physical, psychological, and behaviour. The inability to answer these demands is very likely a trigger for work stress, that work stress is a situation where a person faces a task or job that cannot or cannot be reached by his / her abilities. The purpose of this study was to determine the work stress of health workers (nurses, midwives and doctors) and to determine work stress based on aspects of work stress (physiological, psychological and behavioral) in health workers at Naibonat Hospital, Kupang Regency. This type of research is quantitative research. The total sample was 110 health workers, namely 51 nurses, 49 midwives and 10 doctors. In this study, using descriptive analysis to determine the work stress between nurses, midwives and doctors. The results of the descriptive analysis state that there is a comparison of work stress between nurses, midwives and doctors as well as aspects of work stress in terms of aspects (physiology, psychology and behavior) in health workers at Naibonat Hospital, Kupang Regency.

A generic algorithm for computing optimal ergonomic postures during working in an industrial environment

The present study tries to decrease the risk of work-related musculoskeletal disorders for industry workers by proposing a generic algorithm that recommends an optimal ergonomic posture for accomplishing tasks in an industrial environment. In the case of a dangerous ergonomic pose, the optimization algorithm starts by heuristically changing it to a more ergonomic one. Each recommended posture's feasibility is tested with an inverse kinematic method that can predict the worker's behavior for accomplishing a task. This iterative optimization procedure continues until the optimal ergonomic pose for the worker is achieved. The algorithm's validity is tested in thirteen cases, people with different gender (50 percent male, 50 percent female) aged between 20 and 35, and different height and body morphologies. According to studies, there is a connection between musculoskeletal disorders and the wrong posture for accomplishing tasks in industries. We suggest an optimization algorithm that can indicate the worker the optimal ergonomic pose by considering task constraints in real-time.

Utilizing safety rule correlation for mobile scaffolds monitoring leveraging deep convolution neural networks

Falls from height (FFH) are still a leading cause of fatalities in the construction industry, which also includes scaffolding-related accidents. Despite regular safety inspections, numerous scaffolding-related accidents occur at the construction site. The current safety monitoring practices are not only impractical but infeasible due to dynamicity of construction environment. Since a separate computer training and detection process is generally required to acquire spatiotemporal reasoning to control a single hazard; thus previous efforts in vision intelligence applications to improve safety monitoring are still limited to specific hazards. Also, in regard to detecting unsafe situations based on extracted correlations from safety rules, to date, previous studies have devoted little attention to this domain. To address these issues, this study proposes a correlation-based approach for mobile scaffold safety monitoring and detecting worker's unsafe behaviors. A deep neural network, Mask R-CNN, was used as classification and segmentation of worker's tasks combined with object correlation detection (OCD) module to identify worker's unsafe behaviors. The approach divides the overall construction worker's safety into two subsets, classification of worker and detection of safe (class-1) and unsafe (class-2) behavior using OCD block. The overall performance was evaluated on set of real scenarios with test results showing 85 % and 97 % precision and recall for class-1 (safe behavior) and 91 % and 65 % precision and recall for class-2 (unsafe behavior). The overall accuracy of 86 % confirms the Mask R-CNN-based OCD module's applicability for detecting worker's unsafe behavior effectively in a construction environment.

Pengaruh Pengetahuan Keselamatan dan Kesehatan Kerja (K3) Terhadap Perilaku Pekerja dan Kecelakaan Kerja Pada Proyek di DS LNG Kabupaten Banggai Propinsi Sulawesi Tengah

In association with the potential risks of work accidents in the implementation of construction work, the knowledge of K3 on a construction project is now a fundamental requirement. Aspects of K3 itself will not be able to be run as it should without any intervention from management in the form of a planned effort to manage it (safety management), which is often called the Occupational Safety and Health Management System (SMK3). This research aims to know effects of the knowledge of K3 on the behavior of construction workers as viewed from several aspects related to K3 such as the influence of knowledge variables K3 together to the behavior of construction workers, the effect of knowledge variables K3 partially on the behavior of construction workers and the effect of worker's behavior on work accident.This research were conducted in four construction companies which executed works given by the local government of Luwuk Banggai Regency in 2016. The research approach used in this research is survey method and regression and correlation analysis method having samples of 129 workers. Based on statistical test of hypothesis test, the test result of each K3 knowledge variable shows that all the variables tested (5 K3 knowledge variables ie devinition and initiation K3/X1, K3/X2 management system, personal protector K3/X3, facilities and infrastructure K3/X4, K3/X5 risk) has a strong correlation to worker behavioral variables (Y1). This is evidenced by the correlation numbers R> 0.8 and the determination (r2)>0.7. However, based on the results of simultaneous test (F test) to know the correlation of the five variables of K3 knowledge together to the variable of worker behavior (Y1), the result of statistical test on the simultaneous test shows that in t test (partial) only 2 K3 Good correlation to worker behavior (Y1) that is variable of personal protective device (X3) and K3 risk (X5). According to these two test, it revealed that linear multiple regression result in an equation: Y=0,318X3+0,557X5+1,613 with determinant coefficient (R2) = 71.4 % which means that the model resulting having very good performance.

Faktor yang Berhubungan dengan Perilaku Penggunaan Full Body Harness di Proyek Pembangunan Apartemen oleh PT. X

Working at height is an important component in construction work, using a Full Body Harness (FBH) to prevent the risk of falling from a height. Needs an effort to control accidents in the workplace, that is by using an FBH. This study aims To see and learn the factors related to the behavior of the workers at height in using an FBH in the apartment project of X Company. This study method Using a cross-sectional design. Using a total sampling of 65 workers. This research shows that 81,5% using an FBH. There is a correlation between knowledge (p-value=0,001), attitude (p-value=0,001), OSH training (p-value=0,001), and the availability of FBH (p-value=0,001), but there is no correlation between the level of education (p-value=1,000), and work period with the behavior of using an FBH. There is a correlation between behavior, OSH training, availability of FBH on apartment project at X Company of 2020. The worker should use their knowledge and behavior that are received from OSH training and the company must keep the availability of FBH for workers so it will support the worker's behavior in using an FBH.

WORKPLACE REFORM WITH CHANGING MANAGEMENT THROUGH THE USER PARTICIPATION WORKSHOP : THE CASE STUDY OF SEIYO CITY OFFICE

The research explains about workplace reform, aimed at improving productivity of General Affairs and Policy Planning department of Seiyo officeby changing management through the user participation workshop at 4th floor of Seiyo city office and on the changes of workplace reform. The purpose of this research is to find the changes that are worker's behaviour and worker’s awareness of workplace through workplace reform. The researchers surveyed changes, worker's behaviour and worker's awareness of workplace using workplace reform at 4th floor of Seiyo office as case study. In workplace reform, in order to create a place where new work style can be practiced, the researchers conducted the user participation workshops with workers a total of 6 times. Through the workshops, concept of work style and plan of renovation were proposed. In addition, the researchers did a survey using two methods which were a set of questionnaire and 3 observationsthat is before the workplace renovation, 3 months after the renovation, and 1 year and 3 months after the renovation. The findings obtained from the questionnaire in the first 3 months after the renovation showed that the opinions of the workers were divided between pros and cons against workplace reform. However, the survey of 1 year and 3 months after the renovation showed that almost all workers are satisfied with the new environment. In addition, the researchers found that a positive correlation exist between participation rate of workshops and the satisfaction level. The findings suggest the worth of workshops for workplace reform. In the Observation Survey, the workers needed to select a place freely where they can work comfortably after the workplace reform. For example, they chose to work in refresh space. In addition, the findings from the survey showed that the floor became livelier when the participation rate increses at that workplace. Additionally, the participants became more conscious of the work style such as features of work style, after workplace renovation; they are able to clearly differentiate between short intermittent works separated by conversation and phone and personal work on concentration.

The Effect of Organizational Culture Items on Entrepreneurial Behavior of Knowledge Workers in Iranian Knowledge-based Companies

Today, developing entrepreneurial environment within the organisation has become the basic need of many organisations. Since organisational culture affects all organisational processes, organisations are creating their own culture so as to facilitate entrepreneurial behaviours. This study aims to determine the effect of organisational culture items on entrepreneurial behaviour of knowledge workers of Iranian knowledge-based companies, through servant leadership mediator. The statistical population includes all knowledge workers of Iranian knowledge-based companies in Isfahan City. Based on Krejcie-Morgan table, size of the sample (n = 165) is determined. The research is conducted in descriptive-analytical manner and data collection is done through questionnaire. Then, collected data is analysed through PLS Software. The results suggest that certain aspects of organisational culture (involvement culture, adaptability culture, consistency culture, and mission culture) affect worker's entrepreneurial behaviour significantly. In addition, servant leadership mediates in the association between organisational culture and entrepreneurial behaviour of knowledge workers significantly.

Influencing Factors of Knowledge Workers' Innovation Behavior Based on Self-management

Knowledge workers' innovative behavior is an important driving force for enterprise development. The paper explores the influencing factors of knowledge worker's innovation behavior through the self-control ability and achievement motivation of knowledge workers. In the paper we introduce achievement motivation in the relationship between self-control ability and innovative behavior, built a relationship model for knowledge workers' influencing factors of innovation, and the model is validated by regression analysis of questionnaire data. The results show that the self-management ability of knowledge workers has a significant positive effect on innovation behavior, and the achievement motivation plays an intermediate role between them. Enterprises can influence knowledge workers’ innovative behavior by interfering with self-management and achievement motivation of them.

An Integrated Optimization System for Safe Job Assignment Based on Human Factors and Behavior

Industrial safety has been deeply improved in the past years, thanks to increasingly sophisticated technologies. Nevertheless, 2.3 million people yearly die worldwide due to occupational illnesses and accidents at work. Human factors can be profitably used for safety improvement because of their influence on the workers’ behavior. This paper presents an integrated optimization system to help companies assign each task to the most suitable worker, minimizing cost, while maximizing expertise and safety. The system is made of three modules. A neural module computes each worker's caution for every task on the basis of some human factors and the worker's behavior. To solve the multiobjective job assignment problem, an evolutionary module approximates the Pareto front through the nondominated sorting genetic algorithm II. Pareto-optimal solutions then form the alternatives of a multicriteria decision-making problem, and the best is selected by a decision module jointly based on the analytic hierarchy process and the technique for order of preference by similarity to ideal solution. Validation was carried out involving two footwear companies, where personnel was recruited and reassigned to tasks, respectively. Comparing the worker-task assignment proposed by the system to the one suggested/used by the management, noteworthy low-cost improvement in safety is shown in both scenarios, with low or no decrease in expertise. The proposed system can, thus, contribute to get safer workplaces where risks are less likely and/or less harmful.

Analyzing the Cause of Left-Behind Children by Bourdieu’s Practical Theory

At present, the related research on the causes of “left-behind children” is very seldom. Most of literatures are simply summarized as two points: farmers need to survive, and it is the choice of the subject; the second is the inevitable process of China’s economic and social development and the objective necessity. In this paper, Bourdieu’s Practical Theory, such as Field, capital and habitus three elements, is analyzed and the behavior of workers is explained. It is considered that the phenomenon of left-behind children appearing in large scale in China is not only a problem of economic development, but also a special habitus of “working”, which is not simply the individual choice behavior of the parents of left-behind children.

Adaptive Task Scheduling for an Assembly Task Coworker Robot Based on Incremental Learning of Human's Motion Patterns

Future robots are expected to share the same workspace with humans and work in cooperation with them to improve productivity and maintain the quality of products. Considering this situation, we have developed a novel assembly task co-worker robot to support workers in their task by delivering the parts and tools to workers. Although such systems have improved work efficiency by predicting human's motion patterns, it is necessary to collect worker's data in advance and regenerate its model whenever the worker is changed. In this letter, we extend the previous system by installing an online learning algorithm and create a worker-dependent model without collecting data in advance. Trajectory prediction with high precision can be realized because of the worker-dependent model and effective utilization of the regularity of the worker's behavior. An adaptive task scheduling system based on the predicted result of the worker's behavior is proposed for improving work efficiency. Implementing the proposed algorithm, we evaluate the effectiveness of the task scheduling system by experiment.

作業者の運動情報を利用した作業進度の推定とそれに基づく人協調ロボットのための作業支援スケジューリング

We have been developing a co-worker robot which works in cooperation with workers for an automobile assembly line. The co-worker robot is not directly involved in the assembly processes but carries out some nonessential tasks for supporting workers. In this paper, we improve our old system which decides a delivery timing based on logistic regression model. We propose a method to estimate a worker's current task for improving performance of timing decision system. To achieve these, the worker's behavior is modeled combining two probabilistic techniques: Gaussian mixture model for classifying areas corresponding to each task and hidden Markov model for modeling and recognizing a worker's action. By estimating a worker's behavior using a worker's kinetic information and supporting the worker at the proper timing, this system improves work efficiency and supplies the part to the worker effectively.
