Waste water from oil palm mill can be utilized for irrigation and fertilization on plantation land (land application) because it contains nutrients required by plant and its capability to decrease negative impact on environment. The waste water was sprayed on oil palm plant having 4 months, 8 months and 12 months old. This study was conducted within plastic house using Factorial Completely Randomized Design which consisted of liquid waste concentration with 6 levels as well as oil palm plant ages with three replications. The research objective was to determine the respond of oil palm plant at different ages to the addition of liquid waste concentrations from oil palm mill. The plants were planted within drum consisting of soil from tidal swamp land and liquid waste from private oil palm mill in Banyuasin District. Liquid waste characteristics of oil palm mill from anaerobe pond were as follows: BOD = 24,820.2 mg/l, N =  650.2 mg/l, P = 25 mg/l and K = 295.1 mg/l. Data was tested by using statistical method to determine treatments effect and followed by difference test amongst treatments. The results showed that plant age treatments had highly significant effect on plant height, numbers of stem and plant dry mater weight. Treatment of liquid waste doses had highly significant effect on plant height in 5 months after treatment and plant dry matter weight. Interaction between liquid waste doses and plant ages had no significant effect. Treatment of 12 months plant age and liquid waste of oil palm mill at dose of 2,500 mg/l was significantly different from other treatments. Keywords:  Waste Water of Oil Palm Mill -Plant Age – Plant Growth

The urgency of the researched problem is connected with the growing role of mass media in modern conditions leads to change of values and transformation of identity of the person. The active growth of the role of the media, their influence on the formation and development of personality leads to the concept of “media socialization” and immutation in the media. The aim of the study is to outline the possibilities of the process of media socialization in the context of immutation in the media. The methods of our research are: analysis of pedagogical, psychological, literature, synthesis, comparison, generalization. The article analyzes the views of domestic and foreign scientists on the problem of immutation in the media and the transformation of the information space. In the context of the mass nature of the immutation of society, the concept of “media socialization” becomes relevant, which is the basis for reducing the negative impact of the media on the individual.The author identifies the lack of a thorough study of the concept of “media socialization” in modern scientific thought. Thus, media socialization is associated with the transformation of traditional means of socialization, and is to assimilate and reproduce the social experience of mankind with the help of new media.The article analyzes the essence of the concepts “media space”, “mass media” and “immutation”. The influence of mass media on the formation and development of the modern personality is described in detail.The study concluded that it is necessary to form a media culture of the individual, to establish safe and effective interaction of young people with the modern media system, the formation of media awareness, media literacy and media competence in accordance with age and individual characteristics for successful media socialization. The role of state bodies in solving the problem of media socialization of the individual was also determined. It is determined that the process of formation of media culture in youth should take place at the level of traditional institutions of socialization of the individual.The author sees the prospect of further research in a detailed analysis and study of the potential of educational institutions as an institution and a means of counteracting the mass nature of the immutation of society.Key words: immutation, media socialization, mass media, media space, information.

ABSTRACTBackgroundVarious surveys have documented a negative impact of the COVID-19 pandemic on the population’s mental health. There is widespread concern about a surge of suicides, but evidence supporting a link between global pandemics and suicide is very limited. Using historical data from the three major influenza pandemics of the 20th century, and recently released data from the first half of 2020, we aimed to investigate whether an association exists between influenza deaths and suicide deaths.MethodsAnnual data on influenza death rates and suicide rates were extracted from the Statistical Yearbook of Sweden from 1910-1978, covering the three 20th century pandemics, and from Statistics Sweden for the period from January to June of each year during 2000-2020. COVID-19 death data were available for the first half of 2020. We implemented non-linear autoregressive distributed lag (NARDL) models to explore if there is a short-term and/or long-term effect of increases and decreases in influenza death rates on suicide rates during 1910-1978. Analyses were done separately for men and women. Descriptive analyses were used for the available 2020 data.FindingsBetween 1910-1978, there was no evidence of either short-term or long-term significant associations between influenza death rates and changes in suicides. The same pattern emerged in separate analyses for men and women. Suicide rates in January-June 2020 revealed a slight decrease compared to the corresponding rates in January-June 2019 (relative decrease by −1.2% among men and −12.8% among women).InterpretationWe found no evidence of short or long-term association between influenza death rates and suicide death rates across three 20th century pandemics or during the first six months of 2020 (when the first wave of COVID-19 occurred). Concerns about a substantial increase of suicides may be exaggerated. The media should be cautious when reporting news about suicides during the current pandemic.

The article is devoted to the study of the problem of alienation of peasants from the land in the period from the mid-1960s to mid-1980s in the context of the agrarian policy carried out during these years. The analysis of the complex nature of this problem is given on the basis of the extensive material of journalistic works by “village prose” writers, on the basis of archival and other historical sources. The author identifies and studies reasons for the alienation of the peasantry from the land in those years, such as: further stateization, centralization and concentration of agricultural production; its centralized planning; introduction of guaranteed wages; negative impact from the media and popular culture; rural inferiority complex; lack of brides in the countryside; the policy of eliminating unpromising villages.

The importance of media education in our present time lies in its supposed role in rationalizing the youth’s use of digital media, as the school is no longer able to continue its knowledge and educational pioneering role in light of the excessive and absurd use of the Internet, just as the teacher is no longer a main source of science and knowledge. Considering the study curricula, addressing the negative impact of the excessive use of digital media on the school, as well as addressing the decline in the role of the family and its withdrawal from educational competition with the school, and thus education has lost the mandate of the school and the family to educate the new generation in favor of the hegemony of the new media authority, which is called metaphorically. Fifth, which overtook all authorities, including the authority of traditional media (the fourth power), so that control over the child went beyond control of his family and parents, and the challenge became before those concerned with education, how can the new media be a source of education, entertainment, education, guidance and direction, and in various methods of influence, By using multiple and amazing techniques that are characterized by transcending the limits of time and space, and according to that the great impact of the new media, we see a decline in public education. Illiteracy and its limited means, as well as retreating and losing its control over the social environment, which calls on researchers to study ways to rationalize media education, enhance human awareness of the media, and give it the largest share in influence and direction, and in social upbringing and raising young and old together.

The text analyzes social media in terms of the possibility of conducting a democratic debate through them. Initially, their users had great hopes to do so. Social media were to be not only a tool for expressing opinions or presenting statements but also for disseminating the model of liberal democracy. However, the business model of these media, as well as content filtering algorithms, introduced to protect users against information overload, prevented this from happening. To prove this thesis, the author referred to Sunstein's public forum doctrine and proved that social media do not constitute its equivalent. Although the media provided a space for discussion, they did not ensure equal access for senders of messages to recipients and recipients to a variety of content. The topic of the negative impact of social media on liberal democracy is already raised in English scholarship (and is already present in Poland through its translations) and it is also gradually gaining academic currency among Polish researchers. What constitutes a novel contribution to the already available research is the presentation of social media in the context of the utopian high hopes the media initially raised.
