Abstract

Epistemologically science is built on the basis of methodologies derived from the nature of reality that is believed to be true. epistemology of course determine the character of knowledge, even determine the truth What is considered acceptable and what should be rejected. When the body of knowledge which was classified, or arranged systematically with the correct method, then it can be epistemology. To further emphasize the importance of science, the Quran provides questions a test to them. Quran as a source of knowledge to justify the source of knowledge that has been discussed by philosophers such as emperisme, rationalism, intuition and revelation to note that all the sources of that knowledge to work in their respective areas. Quran as a book of instructions and guidelines on human life, of course covers a range of information that is scientific. Therefore, the Quran has a close relationship with science. Where the Quran provides the basics about science or the Qur’an laid the universality of science

Abstract

 Environmental change always occurs continuously in the process of development of a country. This development is directly orindirectly will affect the order of social life, economy, culture, technology and lifestyle community. The changes in the economic, social community of course affect the marketing system in the country. A very rapid technological developments lately has affected all areas of human activity. The development of this technology has tightened competition in the marketing system in the marketing world, where the procedures must innovate continuously in order to win and retain the loyalty of its customers.    Currently in Indonesia there are nine mobile operators include (indosat, Telkomsel, XL, Mobile-8, Three, Flexi, Esia, Smart and Axis). When walking in the center of mobile sales, mobile phones can be seen many types of operators who have their own packaging designs appeal to consumers.    Display a bundle is now realized by the manufacturer is no longer only have the function of protecting and wrapping products but products that increasingly tight competition in the market requires manufactures to think hard in improving the function of packaging to be able to provide attraction to consumers through the artistic aspect, color, graphic, from or the design.    The results of simple correlation analysis found a correlation between changes in the new packaging with the purchase of consumer preferences is 0.293. this suggests that there is a strong relationship between the new packaging Esia with consumer purchasing preferences. While the relationship is positive because it is positive. This means that the new packaging Esia has a strong positive relationship towards the purchase of consumer preferences. This relationship is positive where this Esia packaging changes increase consumer purchasing preferences of Esia.    Analytical results obtained coefficient of determination coefficient of determination between the change in the new packaging with the purchase of consumer preferences is the 0086 (8.6%). This suggests that the level of consumer preferences towards new product packaging can be influenced by the old product by 8.6%, the remaining 91.4%influenced by other factors. The coclusion is that between the old and new packaging packaging there is a correlation effect on customer preferences in choosing which 8.6% can be seen that the old product is still influencing new product, and the remaining 91.4% is another factor affecting.

Abstract

Negotiations as a cooperative process naturally also contain competition, particularly towards negotiating partners who induce envy. Three components of envy i.e. (i) pain due to inferiority which either manifests in (ii) benign envy to improve the envier performance, or (iii) malicious envy that contains hostility and intention to hurt the envied, may motivate deceptive negotiation strategies. Regardless of the role of envy, individual differences in trait self-control and trait mindfulness may also predict deception. In this cloud-based online experiment, participants (N = 804 students) completed self-reported measures of trait self-control and mindfulness, read an envy scenario on their academics failure compared to the envied classmate, then randomly received the envy conditions (benign vs. malicious), filled in measure of state envy, read the negotiation scenario, and filled in measure of deception. We found that (i) at correlational level, deception was positively associated with all envy components but negatively associated with both individual differences, (ii) at prediction level, malicious and pain of envy predicted more deception, (iii) after taking into account the envy role, only trait self-control predicted lower level of deception. These findings may help improve ethical practices in negotiation context.

Abstract

Perkerasan jalan beton semen atau secara umum disebut perkerasan kaku, terdiri atas pelat (slab) beton semen yang terletak langsung diatas tanah dasar, atau diatas lapisan material granuler (subbase) yang berada diatas tanah dasar (subgrade). Perkerasan kaku menyebarkan beban ke area yang lebih luas ke tanah dasar, sehingga bagian terbesar dari kekuatan struktur perkerasan diberikan oleh pelat betonnya sendiri. Perkerasan beton dapat berupa pelat beton tanpa tulangan, diberi sedikit tulangan, diberi tulangan secara kontinyu, prategang atau beton fiber. Perkerasan kaku akan mengalami defleksi akibat beban lalu-lintas, atau melengkung akibat beda suhu antara bagian atas dan bawah pelat             Jalan Arief Rahman Hakim Kota Bontang merupakan jalan Provinsi yang menghubungkan antara Kota Bontang dan Kabupaten Kutai Timur. Ruas jalan tersebut sebagian sudah di lakukan perkerasan kaku dan sebagian masih memiliki existing jalan beraspal, dengan kondisi sebagian titik terjadi kerusakan yang diakibatkan oleh beban kendaraan yang melintasi jalan tersebut. Ditambah lagi curah hujan di daerah Kalimantan Timur cukup tinggi yang menambah faktor kerusakan jalan makin tinggi. Ruas jalan tersebut cukup ramai dilewati oleh kendaraan ukuran sedang. Dengan melihat beban kendaraan yang melintasi ruas jalan tersebut, maka perlu mengadakan perencanaan terhadap tebal perkerasan tersebut.Pengambilan data dilapangan yaitu data lokasi jalan tersebut, data laju harian rata-rata (LHR) dan dokumentasi. Data?data pendukung lainya, diperoleh dari Instansi terkait. Sedangkan metode perbandingan tebal perkerasan kaku menggunakan metode bina marga 2013 dan metode NAASRA.Dari hasil perhitungan dapat disimpulkan bahwa analisa tebal perkerasan kaku ( Rigid Pavement ) pada ruas Jalan Arief Rahman Hakim Kota Bontang dengan metode bina marga 2013 yaitu diperoleh tebal pelat beton 26 cm dan  metode NAASRA 1987 yaitu diperoleh tebal pelat beton 19 cm. Berdasarkan hasil perhitungan tebal perkerasan diperoleh perbandingan tingkat efesiensi dimensi tebal perkerasan kaku yaitu nilai perbandingan metode bina marga 1,00 dan metode NAASRA 0,73.
