Pine sap exploitation is growing because demand for pine sap in Indonesia and the world is increasing. Pine sap productivity is influenced by several factors including tapping, tree species, diameter, and age of stands. In the tapping method, one of them is the renewal time of tapping with the quarre system which is supposed to save the tapping area and get the maximum sap. This paper studies the effect of the renewal of the pine tree tapping at different ages on the productivity of the sap. The proposed method is a survey with a purposive sample determination with 3 different treatments, namely treatment A of the 3-day quarre renewal, treatment B of the 5-day quarre renewal, and treatment of the renewal of the 7-day quarre by administering stimulants. Performed at different age classes IV, VI, and VIII. Field observational data is then processed using a factorial Completely Randomized Plan analysis with two factors. The results showed that the renewal of quarre had a significant effect on the average productivity of pine tree sap at 95% confidence intervals (α = 0.05). The highest average productivity on treatment B renewal of 5 days quarre was 12.17 grams /quarre/day at age classes VI and the lowest average productivity was at treatment C of renewal of 7 days with 4.61 grams /quarre/day at age classes IV.

Education is an important factor in human life. According to Ki Hajar Dewantara, education is a civilizing process that a business gives high values ??to the new generation in a society that is not only maintenance but also with a view to promote and develop the culture of the nobility toward human life. Education is a human investment that can be used now and in the future. One other important factor in supporting human life in addition to education, which is technology. In this globalization era, technology has touched every joint of human life. The combination of these two factors will be a new innovation in the world of education. The innovation has been implemented by Raharja College, namely the use of the method iLearning (Integrated Learning) in the learning process. Where such learning has been online based. ILearning method consists of TPI (Ten Pillars of IT iLearning). Rinfo is one of the ten pillars, where it became an official email used by the whole community’s in Raharja College to communicate with each other. Rinfo is Gmail, which is adapted from the Google platform with typical raharja.info as its domain. This Rinfo is a medium of communication, as well as a tool to support the learning process in Raharja College. Because in addition to integrated with TPi, this Rinfo was connected also support with other learning tools, such as Docs, Drive, Sites, and other supporting tools.

AbstractHere, we report the recent discovery of 87 Neandertal footprints on the Southwest of the Iberian Peninsula (Doñana shoreline, Spain) located on an upper Pleistocene aeolian littoral setting (about 106 ± 19 kyr). Morphometric comparisons, high resolution digital photogrammetric 3D models and detailed sedimentary analysis have been provided to characterized the footprints and the palaeoenvironment. The footprints were impressed in the shoreline of a hypersaline swamped area related to benthic microbial mats, close to the coastline. They have a rounded heel, a longitudinal arch, relatively short toes, and adducted hallux, and represent the oldest upper Pleistocene record of Neandertal footprints in the world. Among these 87 footprints, 31 are longitudinally complete and measure from 14 to 29 cm. The calculated statures range from 104 to 188 cm, with half of the data between 130 and 150 cm. The wide range of sizes of the footprints suggests the existence of a social group integrated by individuals of different age classes but dominated, however, by non-adult individuals. The footprints, which are outside the flooded area are oriented perpendicular to the shoreline. These 87 footprints reinforce the ecological scenario of Neandertal groups established in coastal areas.

The paper addresses the importance of the role of women in Intelligence and National Security with the specific purpose to highlight the quality of female contribution in all different domains. The world is changing and in this change, Intelligence risks being left behind as never before. An epic evolution and change are underway that will upset ways of being and ways of thinking. All this not suddenly and all this without realizing it if not after the fact. The world is changing, women “are gain the upper hand” taking over also numerically and it is not realized that a change must happen in the field of Intelligence with a space left to women, not because they are women but because of their abilities. In all domains, from strategic to an operational one. Blindness to change that many Agencies are having. And those who are making changes often do so because they are obliged by the rules but not by evaluating the concrete capability of individuals. Two factors risk being explosive if no action is taken. The paper highlights the physiological and psychological contribution of the female component in the National Security and Intelligence work, and why diversity is scientifically important to successfully conduct operational and strategic tasks. It also describes the existing lack of models, how to enlarge the interest of young girls to join the Intelligence Community, and a look into the near future regarding the training and the recruitment processes with specific regards to women.

The UK, as far as we can discover, is currently the only country in the world that has an expertise database for its research community. It is one of the few countries that entrusts this sort of development to the private sector. I would like to look at how this has come about, comment on two factors that I think have influenced the outcome - namely size and quality - say something about who uses the database and where it is all leading.

ABSTRACT: Jihad has been an integral part of Islamic discourse from its early days until today. This research was conducted to determine variations in the meaning of jihad that developed in Mulawarman University students. I use Paul Ricoeur's theory of Social Hermeneutics to explain how the process of interpreting meaning from a text. Ricoeur views that text has a life of its own regardless of the author's intention or intent (text autonomy). In interpreting the text, Ricoeur also argues that understanding and explanation are not two contradictory methods of interpreting the text. The workings of Paul Ricoeur's social hermeneutics include three factors, namely the world of text, the world of presenters, and the world of readers, whereas in this paper there are only two factors, namely the world of text and the world of readers. Jihad in al-Qur'an is repeated 41 times in 23 verses and by Ibn Al-Qayyim it is divided into four meanings, namely jihad against lust, jihad against Satan, jihad against infidels, and hypocrites, and jihad against injustice and wickedness. Meanwhile, readers only divide jihad into two meanings, namely jihad against lust and war jihad. In the process of interpreting, readers are greatly influenced by the trajectories of life that they have been through. This can be seen from the many meanings of jihad they express, namely war, defending, doing good, effort/strength, being serious, preaching, and enthusiasm. ABSTRAK: Jihad merupakan bagian integral wacana Islam sejak masa awal kedatangannya hingga sampai saat ini. Penelitian ini dilakukan untuk mengetahui variasi makna jihad yang berkembang pada Mahasiswa Universitas Mulawarman. Teori Paul Ricouer tentang Hermenutika Sosial saya gunakan untuk menjelaskan tentang bagaimana proses menafsir sebuah makna dari sebuah teks. Ricouer berpandangan bahwa teks memiliki kehidupannya sendiri terlepas dari intensi atau maksud pengarang (otonomi teks). Dalam menginterpretasi teks, Ricoeur juga berpendapat bahwa pemahaman dan penjelasan bukanlah dua metode yang bertentangan dalam menafsirkan teks. Cara kerja hermenutika sosial Paul Ricoeur mencakup tiga faktor yaitu dunia teks, dunia pemateri dan dunia pembaca sedangkan dalam tulisan ini hanya ada dua faktor yaitu dunia teks dan dunia pembaca. Jihad dalam al-Qur’an terulang 41 kali dalam 23 ayat dan oleh Ibn Al-Qayyim dibagi menjadi empat makna, yakni jihad melawan hawa nafsu, jihad melawan setan, jihad memerangi kaum kafir dan kaum munafik serta jihad melawan kezaliman dan kefasikan. Sedangkan pembaca hanya membagi jihad dalam dua makna yakni jihad melawan hawa nafsu dan jihad perang. Dalam proses penafsirannya, pembaca sangat dipengaruhi oleh trajektori kehidupan yang mereka pernah lalui. Hal ini dapat dilihat dari banyaknya makna jihad yang mereka ungkapkan, yaitu perang, membela, melakukan kebaikan, usaha/kekuatan, bersungguh-sungguh, dakwah serta semangat.

The depletion of traditional organic energy sources and aggravated environmental problems are the reasons why the level of energy efficiency is an important factor in the competitiveness of the national economy. Russia ranks third in the world in terms of total energy consumption and its economy is distinguished by a high level of energy intensity (amount of energy per unit of GDP). In 2019, this figure was 9.62 tons of oil equivalent (toe) per 1 million rubles, which is 40% higher than the world average. The low energy efficiency of the Russian economy is a widely recognized problem. A special decree of the Government of Russia in 2018 sets the task of increasing the level of energy efficiency of the Russian economy by 23% by 2030. One of the ways to solve this problem is the development of nuclear energy, and increasing the competitiveness of nuclear energy is one of the key issues for the national economy. In this connection, solving the problem of assessing the competitiveness of the nuclear industry and its leading companies occupies a key place among the practical scientific problems, the solution of which is facilitated by the results presented by the authors in this article. Rosenergoatom Concern JSC is the leading energy generating company in the Russian nuclear industry. The results of the study of the competitiveness of Rosenergoatom Concern JSC were obtained on the basis of the authors’ methodology for assessing the competitiveness of an energy generating company. The novelty of the presented methodology lies in the developed normative and evaluative model and the coefficients of competitiveness of an energy generating company. The advantages of the authors’ model are that it allows (1) obtaining integral assessments of the competitiveness of a power generating company at short time intervals for a large number of indicators and (2) quantitatively measuring the effects of different factors on the competitiveness of a power generating company, provided that the grouping of indicators of competitiveness of a power generating company is justified by influencing factors. The two factors considered by the authors were: the general market factor and the industry factor. According to the results of the study, it was found that Rosenergoatom Concern JSC demonstrates positive increase of the competitiveness indicator mainly due to the industry factor. With this regard, it was concluded that, within the framework of state policy, it is advisable to strengthen support for the Russian nuclear industry by creating additional conditions and opportunities for its energy generating companies on the domestic energy market.

Politics is regarded in many parts of the world, especially in Africa, as a space meant exclusively for men. Therefore, women venturing into politics are made to believe that they are misfits, and the idea is anathematized and strangulated from the outset by those who are supposed to encourage the women. It is popularly believed that it is natural for men to rule over women, while it is considered abnormal and unnatural for women to rule over men. Although different societies have at one time or the other in history been ruled by queens and female warriors, at least, that is not usually seen as bizarre in societies that practice monarchical or imperial rule. In a democracy, however, a lot of people vehemently oppose the idea of a woman vying for a political office. In the case of Africa, two factors are responsible for this: the African people’s colonial experience and the bifurcation of the social sphere into public and private spaces. This has entrenched gender roles into the scheme of social reality held by the people. The people hold that certain roles must be performed by women while certain roles are exclusively for men. This culture has made it increasingly difficult to achieve parity and egalitarianism in gender relations in contemporary Africa and to achieve meaningful development in Africa. This article suggests ideological decolonization as a way out of the current predicament of the African women as the subaltern in the patriarchal and hostile political space of contemporary Africa.

We learn regularities in the world around us, frequently without conscious effort, a phenomenon known as implicit learning. These regularities are often impossible to verbalise. One example of implicit learning is the structural effect, in which participants learn a rule set combining two factors, such as lexical frequency and concreteness. Theories of implicit learning predict that repetition of exemplar words would result in improved learning of the rule set, increasing the magnitude of the structural effect. Over four experiments, we demonstrate that this is, in fact, not the case. In Experiments 1 and 2, three repetitions of exemplar words result in superior item memory, but no change in the magnitude of the structural effect, compared with individually presented words. In Experiments 3 and 4, the structural effect is shown to be invariant to five repetitions of exemplar words and at high and low numbers of exemplars. In all four experiments, participants were unable to describe the rule set underlying the structural effect. However, confidence ratings demonstrated sensitivity to the structure and this sensitivity, unlike endorsements, increased with strength. The results are discussed in reference to differentiation, structural versus judgement knowledge, and flexible learning systems.

Wheat [Triticum aestivum (Linnaeus) Em. Thell] belongs to family Gramineae, believed to have originated from South West Asia. It is most important cereal cultivated crop in temperate area of the world. Wheat is second important staple food crop after rice. In field condition the termite (Odontotermes obesus Rambur) is predominant insect-pest causing 20-40% damage to the crop particularly in rainfed condition. For the management of termite in wheat, Krishi Vigyan Kendra demonstrate the technology - Seed treatment by Fipronil 5% SC @ 6 ml./ kg seed before sowing and soil treatment by Fipronil 5 % SC @ 1.6 lit./ha. During 2016-17 and 2017-18 at farmers field in adopted village of KVK conduct the demonstration. Under the technology, reduce the termite infestation 53.46 per cent resulted18.92 per cent enhance the productivity of wheat crop. Under IPM technology, the average productivity of chickpea is 3865 Kg/ha whereas in farmers practice, the average productivity of chickpea is 3250 Kg/ ha.

Abstract The development of the IPTEK (Science and Technology) world has brought tremendous benefits for the advancement of human civilization. The types of work that previously demanded considerable physical capability, are now relatively can be replaced by automatic machine devices. The working system that has been over-enabling human energy with the science and sophistication of technology is amazing. The civilization of the nation and the world society in the future is understood and realized will be faced with the complex situation in various branches of science. Therefore, to power, the IPTEK is required lofty values to be accountable. The debate that IPTEK's contributions with the development of an area the Islamic economic system is still ongoing. This is due to the absence of a theory, research, or model that can explain the relationship between the two factors above. It takes a test using a valid method to generate an accurate conclusion on the development and contribution of IPTEK applications with the development of the Islamic economic system. Nevertheless, some communities still believe that IPTEK's contributions to the development of the Islamic economic system of a particular region.
