Plankton is one of the biological resources that have an important role in the marine ecosystem. Plankton life is strongly influenced by the water quality parameters, one of which is the content of nutrients (nitrates and phosphates). Increased nutrient content caused by the increased load input from human activities. Serangan Island waters including the coastal ecosystem is widely used for a variety of human activities, such as tourism, aquaculture, residential, and transportation. All human activity will affect water quality will lead to an increase in nutrients and organic matter which in turn can lead to changes in water quality chemical physics and structure of plankton. The purpose of this study was to determine the relationship of the abundance and diversity of phytoplankton abundance and diversity of zooplankton and to know the physical parameters - chemical effect on the abundance of plankton. The method used is the Pearson correlation analysis to determine the relationship between abundance and diversity of phytoplankton abundance and diversity of zooplankton, and principal component analysis to look at the parameters of the water the most influence on the abundance of plankton. Results of Principal Component Analysis showed that the waters of the parameters that influence the abundance of plankton varies at each observation station. Pearson correlation analysis showed a strong relationship between the abundance of phytoplankton to zooplankton abundance with a correlation value of 0.64.

This article examines the relationship between learning and behavioural evaluation among religious officers in Malaysia after attending the Manual on HIV/AIDS in Islam Training Programmes organized by the Islamic Development Department of Malaysia (JAKIM). The training programmes were implemented to deliver the most accurate and the latest information on HIV / AIDS as well as to train religious officers in Malaysia to address the issues among Muslims. The training programmes apply the theoretical and practical activities where participants had the opportunity to carry out outreach activities with People Living with HIV / AIDS (ODHA). Quantitative methods through questionnaires were used to obtain data. A total of 350 religious officers who had attended the training programmes were selected as respondents by simple random sampling technique. Pearson correlation analysis was conducted to determine the relationship between the learning and behavioural evaluation. The results of the Pearson correlation analysis found that there was a significant relationship between learning evaluation in terms of the information obtained from programmes’ contents and behaviour evaluation with r = 0.489 and sig = 0.000 (p <0.05) at the medium positive range.. While the relationship between learning evaluation in terms of the information obtained from outreach activities with behavioural evaluation showed a strong positive correlation with the strength values obtained were r = 0.539 and sig = 0.000 (p <0.05). This analysis shows that the information acquired through the training program Manual Islam and HIV / AIDS has been successful in changing the behaviour of religious officers’ awareness in terms of the role of dakwah to ODHA.

Groundwater Dynamic

In the past few decades, the shrinkage of the Aral Sea is one of the biggest ecological catastrophes caused by human activity. To quantify the joint impact of both human activities and climate change on groundwater, the spatiotemporal groundwater dynamic characteristics in the Amu Darya Delta of the Aral Sea from 1999 to 2017 were analyzed, using the groundwater level, climate conditions, remote sensing data, and irrigation information. Statistics analysis was adopted to analyze the trend of groundwater variation, including intensity, periodicity, spatial structure, while the Pearson correlation analysis and principal component analysis (PCA) were used to quantify the impact of climate change and human activities on the variabilities of the groundwater level. Results reveal that the local groundwater dynamic has varied considerably. From 1999 to 2002, the groundwater level dropped from −189 cm to −350 cm. Until 2017, the groundwater level rose back to −211 cm with fluctuation. Seasonally, the fluctuation period of groundwater level and irrigation water was similar, both were about 18 months. Spatially, the groundwater level kept stable within the irrigation area and bare land but fluctuated drastically around the irrigation area. The Pearson correlation analysis reveals that the dynamic of the groundwater level is closely related to irrigation activity within the irrigation area (Nukus: −0.583), while for the place adjacent to the Aral Sea, the groundwater level is closely related to the Large Aral Sea water level (Muynak: 0.355). The results of PCA showed that the cumulative contribution rate of the first three components exceeds 85%. The study reveals that human activities have a great impact on groundwater, effective management, and the development of water resources in arid areas is an essential prerequisite for ecological protection.

Academic stress in students will arise when there is pressure for achievement both in the learning process and the interaction process in school. Academic stress is caused by the inability of students to process perceptions so that the achievement of the learning process is considered as academic demands that exceed the limits of their abilities and also the students' uncertainty about events in their lives can be controlled by themselves. This study aims to determine the relationship of internal locus of control and academic stress of students of SMAN 2 Cimahi. The subject of this research is the students of SMAN 2 Cimahi in the academic year 2018/2019. Measuring instruments in this study were academic stress scale (49 items; α = 0.875) and internal locus of control scale (30 items; α = 0.618). The method of data analysis in this study is Pearson correlation analysis. The results of Pearson correlation analysis based on the significance value p = 0.00 <0.05, which means that there is a relationship between internal locus of control and academic stress. The results of a simple correlation analysis (r) obtained a correlation between internal locus of control and academic stress of 0.610. This means that there is a strong relationship between internal locus of control and academic stress, while the direction of the relationship is positively significant, which means that the higher the internal locus of control, the academic stress will be lower. Internal locus of control effectively contributed 37.2% to academic stress, while 62.8% was determined by other variables not examined in this study.

Abstract The purpose of this study was to investigate the cross-lagged relationships between academic procrastination and test anxiety. A sample of Chinese adolescents from a high school in Changsha City, HuNan Province, China participated in this study. The participants completed the Aitken Procrastination Inventory and the Test Anxiety Scale at two times during a semester. Pearson correlation analysis showed academic procrastination and test anxiety to be positively correlated. Cross-lagged panel analyses demonstrated that academic procrastination at Time 1 predicted test anxiety at Time 2, while test anxiety at Time 1 did not predict academic procrastination at Time 2. Within the limits of the design, we found that academic procrastination may lead to an increase in test anxiety, but test anxiety did not predict the future level of academic procrastination. It is recognised that the relationship between anxiety and procrastination is complicated. It is suggested that a focus on interventions for academic procrastination may help to reduce students’ test anxiety, but not necessarily vice versa.

The Relationship

Manipulation which is a type of social influence occurs when a person influences and operates another person by changing their thoughts or behaviors. Manipulation differs from its purpose. Harmful manipulation has features such as suppressing the person by manipulating the person, restricting free will and showing implicit aggression. At the same time, the manipulator’s motives are hidden and the goal is to benefit the manipulator. Dating violence is defined as being subjected to abuse by husband/ wife, date, girlfriend/boyfriend or ex-partner. The aim of this study is to investigate the relationship between being affected by the manipulation in students’ close relationships and exposure to dating violence in their emotional relationships. This research is descriptive. 200 students between the ages of 18-28 at Yeditepe University participated in the study. Three different questionnaire forms were used to collect data. They are respectively demographic form, being affected by the manipulation questionnaire which consists of 20 questions and the exposure to dating violence questionnaire which consists of 42 questions. The answer to each question has an equal coefficient effect. At the end of the exposure to dating violence questionnaire, there is a description of a forensic case and questions about whether the case was resolved or not. Exposure to dating violence questionnaire consists of 7 sub-categories; emotional, verbal, social, physical, economic, sexual and digital. The mean age of the participants is 22,08±2,03. Participants consist of students who 48% (N=96) are men and 52% (N=204) are women. According to Pearson Correlation analysis; there is a moderately significant positive correlation between exposure to dating violence and being affected by manipulation (r= .319, p <0.001). The findings suggest that when the rate of being affected by the manipulation in the close relationships of participants increases, dating violence increases.
