Abstract

The culture of the Marind tribe of Papua has been preserved for a long time to be preserved until today. like the traditional culture of Marind in the tradition of marriage and wedding parties. The Marind people believe in Islam as their religion. so there is an acculturation process in displaying the practice of the tradition. For this reason, this study will examine the tradition of marriage and walīmat al-‘urs, the Muslim community of the Marind Tribe of Papua in a review of cultural acculturation. Qualitative research is used during the research process. In-depth observations and interviews were applied during data collection. This research shows that the Muslim community of the Marind Tribe of Papua in its implementation still uses the traditions of the past because they respect the customs and minority Islam in the family, practice mixed traditions between the two cultures, and eliminate traditions. While the process of cultural acculturation experienced by the people of the Marind tribe of Papua to the tradition of marriage and marriage parties. So that emerged a new tradition of the Marind Muslim community. This research also results that the Muslim community of Marind tribe upholds the customs that prioritize the appreciation and practice with the content of customary values, but on the other hand also fulfills all matters relating to sharia in Islamic culture. The occurrence of cultural contact meetings between Marind and religious customs, according to this study does not indicate a process of rejection.

Abstract

Layered double hydroxide (LDH) is known as a layered material that can be used as an adsorbent to remove pollutants from aqueous solutions. The use of layered double hydroxide as an adsorbent is not very effective due to its structure which is easily damaged so that it cannot be reused and its small surface area which results in a small adsorption capacity. This can be overcome by developing layered double hydroxide into a composite material. Modification of layered double hydroxide is done by using supporting materials in the form of humic acid and hydrochar. In this study the adsorbent was applied in the removal of Cr(VI) metal from aqueous solutions. The layered double hydroxide modification process was successfully carried out as seen from the XRD, FTIR, and BET analysis. XRD analysis shows the peaks that appear in Mg/Al-AH and Mg/Al-HC are peaks composed of their constituent materials, namely Mg/Al LDH, humic acid, and hydrochar. The vibrations that appear in Mg/Al-AH and Mg/Al-HC are vibrations originating from Mg/Al, humic acid, and hydrochar. The layered double hydroxide material composited with humic acid showed a surface area from 2.155 m2/g to 3.337 m2/g. The layered double hydroxide material composited with hydrochar showed a larger surface area than the Mg/Al LDH base material. The surface area increased 37 times, from 2.155 m2/g to 74.207 m2/g. The Mg/Al-AH composite showed the first adsorption ability of 89.064% and there was no significant decrease in the next cycle. The Mg/Al-HC composite showed adsorption ability in the first cycle which reached 97.079%, the ability to survive up to the fifth cycle with a final ability of 75.029%.
