This study illustrated the physiological and psychological effects of watching videos of different durations showing bamboo forests with varied structures. Physiological indicators, including EEG (electroencephalogram), blood pressure, skin conductance, and pulse, were monitored in 180 Chinese university students (mean age: 20.72 ± 2.56 years) while they were watching bamboo videos. Before and after watching the videos, their psychological indicators, including positive and negative moods, were measured using the Profile of Mood States questionnaire. After watching the bamboo videos of different durations, all of the physiological indicators responded to the stimulation after only 1 min. The indicators showed different trends at 1, 3 and 5 min. EEG decreased and then was maintained at a stable level after 1 min, and the high β, low β, and α waves had no significant differences between 1, 3 and 5 min. Blood pressure dropped to a stable state after 3 min, and the decline was significantly different greater after 3 min than after 1 min. Skin conductance increased for 1 to 5 min, and it did not stabilize after a long time (5 min). Pulse decreased after 1 min but increased after 5 min. After watching the videos with bamboo of varying structures, the physiological and psychological indicators showed significantly different changes. Skin conductance significantly increased (mean value: 6.78%), and the amount of sweat was more effectively reduced, thereby reducing tension, when the students viewed videos of sympodial bamboo forests compared with monopodial bamboo forests. Bamboo forests with a higher canopy density (0.83–0.85) could significantly decrease α waves (mean value: 1.50 Hz), relaxing the human body. High β and low β waves showed greater decreases, with tension reduced more effectively, when bamboo forests with a low tilt ratio (< 1.5%) were viewed. Bamboo forests with neat undergrowth could have more beneficial physiological and psychological effects on the human body.

Stage 1

Noise in the workplace is often a separate problem for the workforce so that it can cause mental-emotional disturbance as well as the heart and circulatory system. According to the 2013 Basic Health Research, the prevalence of high blood pressure in Indonesia at the age of ≥18 years is 25.8%. So the researchers wanted to find a relationship between noise intensity and blood pressure. This research method was observational analytic with a cross-sectional approach conducted at PT. Bintang Intipersada Shipyard, Batam City. The sampling technique was a total sampling with a population of 100 workers in 2018 and obtained results of 61 workers determined by inclusion and exclusion criteria. The results of the study were analyzed with a frequency distribution tabulated and tested with the Pearson Product Moment Test. The results of this study worker who were exposed to noise intensity ≤85 dBA had a normal blood pressure of 8 (36.5%) people, in workers who were exposed to noise intensity ≤85 dBA had blood pressure with Pre-hypertension as many as 12 (54.5% ) people, for workers exposed to noise intensity ≤85 dBA have 1 (4.5%) blood pressure with Stage 1 Hypertension, workers who are exposed to noise intensity ≤85 dBA have blood pressure with Stage 2 Hypertension as much as 1 (4.5 %) person. While workers who are exposed to noise intensity> 85 dBA have normal blood pressure of 0 (0%) people, workers who are exposed to noise intensity> 85 dBA have blood pressure with Pre-hypertension as much as 2 (5.1%) people, workers are exposed to noise intensity> 85 dBA had blood pressure with Stage 1 Hypertension as many as 14 (35.9%) people, then workers exposed to noise intensity> 85 dBA had blood pressure with Stage 2 Hypertension as many as 23 (59%) workers. The results of the Pearson Product Moment analysis value of p = 0,000 <α 0.05, there is a relationship between noise intensity and blood pressure with the magnitude of the correlation coefficient (r) which is 0.795 meaning, there is a strong relationship. Based on this study it can be concluded that there is a significant relationship between noise intensity and blood pressure.

The Relationship

Hypertension is a disease that usually occurs in the circulatory system which can cause an increase in blood pressure above the normal value, which exceeds 140/90 mmHg. The intention of this study aims to understand the relationship between lifestyle and the incidence of hypertension in Antang Makassar Public Health Center in 2018. This research method uses quantitative analytic motives using a cross sectional approach with a population of 46 people and a sample of 36 respondents. This research was conducted on July 14-16 June. The method used is simple random sampling and the tool used to obtain data is a questionnaire. The scale used is Liker and Guttmann scale with univariate, bivariate analysis and chi-square test with significant a = 0, 05. The results of this study indicate there is a relationship between lifestyle and the incidence of hypertension in the Makassar Antang Health Center with P = 0, 01 smaller than the value of a = 0.05. Suggestions are for hypertensive patients, namely the need to check their health routinely to health workers in order to know the development of blood pressure and obtain information from health workers.
