Abstract

We have performed the synthesis and characterization of materials La0.73Ca0.27Mn1-xCuxO3 for 0 <x< 0.19 using  neutron scattering diffraction (HRPD) and SQUID.All the samples are already in phase with the crystal structure  orthorombic and space group P nma. Parameters of the Mn-O bond length obtained from the charactyerization HRPD. From  the parameters of Mn-O bond length can be determined the value of Jahn-Teller distortion. The greater x will result in an  average radius of position B (<rB>) increasing and the tolerance factor t decreasing. From the characterization of the SQUID  was found that the maximum value of conductivity for Cu-doped samples will be lower when compare to the sample without  doping, except for Cu=0.10. If the value of the conductivity is getting smaller, the activation energy will be higher. Keywords: Jahn-Teller distortion, factor tolerance, conductivity, activation energy

Abstract

The marriage of an important transition in the life of man, namely the transition from teenage level towards the level of family life. Undeniable that marriage is an instinctive need for every living being. The transition in life are usually characterized by the presence of religious ceremonies to support the marriage process. Every wedding ceremony that's so important both for those concerned as well as for members of the kinship of both parties.A series of organizing the process of marriage particularly Morotai Sangowo community consists of several stages, ranging from the proposal to the marriage taking place. A normal marriage are usually preceded by the time of the engagement/promise of connective between the men with the woman the length of about one year. Then proceed with the wedding or the inauguration.The culture of marriage and the rules applicable to the community Sangowo that is inseparable from the influences and its environment. Where the community is located as well as the guidelines of the society, influenced by the knowledge, experiences, religious beliefs and embraced by the community Sangowo itself.The custom of marriage Sangowo is a regional cultural heritage of their predecessors who have cultural values and must be preserved and conserved but customs and cultures that how they should preserve and they preserve. Shift the value of marriage in this custom also caused because more and more people who have attended the world of education so that more understanding of the pattern to put forward something that is practical.Keywords: marriage, cultural heritage, religious ceremonies

Abstract

Indonesian ethnic groups depart from members of the community that marriage is a sacred bond and is one of the gifts of the Almighty God that cannot be avoided by mankind. Marriage is not merely a bond between two different men and women but also the process of unification of two families.Marriage is a staple of the culture and the marriage ceremony also has a shift or change. As happened to the life of Toraja people who experience acculturation. In the marriage ceremony of the Toraja tribe community in Lembang Dende ' remained through the stage based on the customary order ranging from the process of the Ma'parampo decay to the stage of the marriage of Rampanan Kapa '.Traditional ceremony of Toraja people's marriage in Lembang Dende ' more clearly know that traditional ceremonies are not merely implemented but must refer to the customs prevailing in Toraja. Marriage procession, especially the customary law contained in it is already a thing that is no longer realized by society so that violations are already a common thing in society. The things that are very fundamental for the Toraja community, especially in Lembang Dende' itself must be preserved so that this culture is not eroded by the time. There are still a lot of elements from the Aluk that will always be refined by all elements of society and hopefully this culture continues to be preserved.Keywords: marriage, ceremony, tribe

Abstract

Efforts to fulfill food security to anticipate population growth in Indonesia need to be supported by universities through research and community service. The application of the Natural Animal Audio Organic Growth System (NA-AOGS) with a STEM (Science, Technology, Engineering, and Mathematics) approach is an effort to help the community increase crop yields and accelerate the growth of soybeans (Glycine max (L.) Merill). The research method used is R&D (Research & Development) which is modified from Cennamo and Kalk (2018). This model is in the form of a spiral cycle using 5 (five) main activities as follows: (1) defining the product conceptual; (2) designing research products; (3) demonstrating the product in a limited trial; (4) developing the product through the process of evaluating the test results, and (5) presenting the product to the public.  The direct impact of learning is the improvement of science process skills and critical thinking of students participating in the Biophysics course at the Natural Sciences Study Program, Universitas Negeri Yogyakarta. This is due to the effective application of STEM to link science learning with contextual technology and engineering (NA-AOGS), environmentally friendly technology (only using natural animal sound frequency variables), mathematical elements in data analysis, and analysis of soybeans plant growth charts. The economic impact of this research is the scientific contribution in the form of adaptation of agricultural technology so that it can increase soybean yields (an increase of 130.38% on an area of 2750 m2). The novelty and contribution of this research is the integration of science learning with agricultural techniques and technology with a STEM approach so that it can improve the welfare of farmers in educational institutions as a new model in science learning.
