Judul: Correlation between Intercultural Communication Competence, Host Interpersonal Communication, and Ethnic Interpersonal Communication with Cultural Adaptation
Abstrak: Gegar budaya akibat migrasi dapat diatasi pendatang dengan melakukan adaptasi. Komunikasi memiliki peran penting dalam proses adaptasi budaya pendatang. Penelitian ini bertujuan untuk menganalisis hubungan kompetensi komunikasi antarbudaya, komunikasi antarpribadi tuan rumah, dan komunikasi antarpribadi etnis dengan adaptasi budaya. Penelitian ini menggunakan pendekatan kuantitatif didukung data kualitatif dengan metode kasus pada pedagang pendatang Jawa di Jalan Babakan Raya. Data dikumpulkan melalui kuesioner, wawancara mendalam, dan observasi lapang lalu dianalisis dengan uji korelasi rank Spearman. Hasil penelitian menunjukkan bahwa tingkat kompetensi komunikasi antarbudaya, komunikasi antarpribadi etnis, dan adaptasi budaya pedagang Jawa bergolongan sedang, sementara tingkat komunikasi antarpribadi tuan rumah bergolongan rendah. Terdapat hubungan positif dan signifikan antara kompetensi komunikasi antarbudaya dengan adaptasi budaya serta tidak terdapat hubungan signifikan antara komunikasi antarpribadi (dengan tuan rumah maupun etnis) dengan adaptasi budaya pendatang., Migrants can overcome culture shock due to migration by adapting. Communication has an important role in the cultural adaptation process of migrants. This study aims to analyze the correlation between intercultural communication competence, host interpersonal communication and ethnic interpersonal communication and cultural adaptation. This research uses quantitative approach supported by qualitative data with a case method of Javanese migrant traders on Babakan Raya Street. The data collected through questionnaires, in-depth interviews and field observations. Data were analyzed using the Spearman rank correlation test. The results of the research show that the level of intercultural communication competence, ethnic interpersonal communication, and cultural adaptation of Javanese traders are in the medium category, meanwhile the level of host interpersonal communication is in low category. There is a positive and significant relationship between intercultural communication competence and cultural adaptation and there is no significant relationship between interpersonal communication (with host or ethnic group) and cultural adaptation of migrants.

Judul: Proses Pengambilan Keputusan Migrasi dan Adaptasi Migran Sirkuler Pedagang Kaki Lima di Kecamatan Pamulang, Kota Tangerang Selatan
Abstrak: The research is intended to study (1) the process of decision making of circular migrants; (2) the process of adaptation of the circular migrants; and (3) the change of social-economic and cultural aspects of circular migrant households. The research shows some factors that significantly influence the process of decision making to migrate in accord with the theory developed by Lee, i.e. (1) the factor originate from the migrants’ homeland as the pushing ones; (2) the factor of the migration destination as the pulling ones; (3) the aspect of obstruction; and (4) the personal factor. In addition to the four factors, this study shows a new aspect accelerates the migration process, i.e. the power of social network among migrants comprising of the earlier migrants who have succeeded in their migration. However, the economic motive and personal decision are two factors which could not be abandoned. The accomplishment of the adaptation is generally induced by personal characters: strong personality, durability, persistence and gallantry to live a difficult life. The external factor strengthening the process of adaptation of the migrants in their new milieu is the availability of the people originally from the same homeland. The success of the circular migrants is also influenced by their ability to maintain and develop certain institutions. They are comprising of (1) entrepreneurial institutions with their networks; (2) the system of remittent transfer; (3) saving and loaning institutions; and (4) social security system. The circular migrants working as moving vendors (PKL) are generally getting additional values as the better change of their social, economic and cultural household aspects. The change is known through several indicators: (1) the improved quality or quantity of their dwellings in their homeland; (2) the increase of their properties or jewelries; (3) the trend of self-ownership among the moving vendors’ businesses; (4) the trend of business income of the moving vendors; (5) the trend of the average of remittent nominal; (6) the trend of marital status of the moving vendors; and (7) the change of the behavioral aspects of the circular migrants from traditional pattern into the more modern one.

Judul: Separation of Neodymium from U3Si2/Al Fuel Plate for Burn-Up Determination
Abstrak: Neodymium is a common fission product produced in nuclear fission reactions. Neodymium in this study was chosen as a burn-up indicator for U3Si2/Al fuel element plates because the neodymium isotope is a stable fission product with a fairly high yield. Some procedures were carried out to separate neodymium, starting with the separation of cesium isotopes (137Cs, 134Cs) through the precipitation method, then separation of uranium isotopes (235U, 238U) and plutonium isotopes (239Pu, 238Pu) with Dowex 1x8 ion exchange resin, and separation of neodymium (Nd), samarium (Sm), as well as cerium (Ce) with Dowex 1x4 ion exchange resin. The Cs recovery reached 99.95%. The U and Pu isotopes resulting from the separation are subjected to an electrodeposition process and the weight of each isotope can be measured with an alpha spectrometer. The separation results of Nd from Sm and Ce have been proven using an XRF spectrometer. The neodymium isotopes separation was corrected using the standard addition method, and an average total Nd content of 2.4 ppm was obtained in the PEB U3Si2/Al bottom solution. It is hoped that this separation method can be applied in determining burn-up of nuclear fuel.
