Abstract

The corn production in Indonesia, based on the data from Badan Pusat Statistik in 2012, amounted to 19.73 million tons, the cornhusk from the corn crop is about 38.38%. The utilization of cornhusk itself has not been maximized yet, so the research to maximize the utilization of cornhusk is required. The research has been made biocomposites cornhusk and Linear Low Density Polyethylene (LLDPE) with hot press method. Biocomposites made with the variation of cornhusk:LLDPE are 30:70, 40:60, 50:50, 60:40, 70:30, and it is characterized of the mechanical characteristics (tensile and tear) with Universal Testing Machine (UTM), biodegradation in a qualitative manner. Mechanical analysis showed the mechanical characteristics decrease with the addition of cornhusk concentration on biocomposites, and concentration 30:70 has the highest mechanical characteristics with tensile strength 24.77 MPa, elongation 19.10% and tear strength 53.94 N/mm. The result is contrast with the biodegradable analysis in which the bigger concentration cornhusk then the level of biodegradability is higher.Keywords: biocomposites, biodegradable,  cornhusk, mechanical characteristic

Abstract

Surah Yusuf is the only Surah in The Quran telling the story of Prophet Yusuf. It contains several important psychological dimensions to teach people about moral. However, the study of psychological dimensions is rarely (or never) conducted. Using thematic method and psychological approach, this article aims to describe and analyze comprehensively the dimensions of psychological emotions of Prophet Yusuf’s story. As a result, this research concludes that there are psychological emotional terms in the story, such as fear (khawf), sadness (ḥuzn), jealousy (ghirah), envy (ḥasad), hate (kurh), joy (faraḥ), lust (shahwah), and regret (nadm). Actually, these emotions are good for self-protection, competition, and self-defense. From the story, humans can learn how to control these emotions well, so they do not fall into difficulty. The reason why the Quran pays attention to psychological emotions in the story of Yusuf is to teach that all humans including the prophets have psychological emotions. So, they should be wise in dealing with emotions and to adjust or control them.
