Abstract

Organic matter and inorganic fertilizer application are important to maintain the existence of potential microbes in the rhizosphere and maintain the soil quality. A greenhouse experiment has been carried out to determine the effect of  vermicompost and NPK fertilizer on total bacterial and Azotobacter  population in rhizosphere and yield of lettuce (Lactuca sativa L.) grown in soil order of  Inceptisols. The experimental design was a factorial randomized complete block design with three replicates were tested three doses of vermicompost (7.5, 15 and 22.5 t ha-1) and four doses of inorganic fertilizers; NPK (300; 450; 600 and 750 kg ha-1). The results showed that there was no significant interaction between vermicompost and NPK fertilizer on either total bacterial or Azotobacter population, as well as on fresh weight of lettuce. Both vermicompost and NPK fertilizer did not affect the biological parameters. However, the application of 750 kg/ha NPK fertilizer can increased lettuce weight up to 24% compared to that of control. This study suggested that in the relatively poor soil nutrients, lettuce growth was depend on inorganic fertilizers.

Abstract

This article attempts to examine M. Dawam Rahardjoʾs interpretation through his two works, Ensiklopedi al-Qurʾan: Tafsir Sosial Berdasarkan Konsep-konsep Kunci (The Encyclopedia of the Qurʾan: Social Interpretation Based on Key Concepts) and Paradigma al-Qurʾan: Metodologi Tafsir & Kritik Sosial (Paradigm of the Qurʾan: Methodology of Interpretation and Social Critique). In the treasures of Indonesian commentary literature, the two works of Rahardjo were unique, new and different at the time they appeared. The presentation in encyclopedic form and discussions that raise social issues make these work one of the pioneers of social-thematic interpretation. By using a descriptive-analytical method and a historical approach, this article attempts to trace and examine the ideas of interpretation in the two works hermeneutically to see how Rahardjo reads the Qurʾan in responding the social problems in society. The results of this study show at least three things: first, that Rahardjo’s interpretation from the beginning was directed to respond to ongoing social issues of his time; second, Rahardjo’s thinking was classified as progressive in his time because he attempts to solve social problems by integrating thematic interpretation with social science approach that he masters; third, his hermeneutical reading of the Qurʾan allows his interpretation to be relevant to the problems that exist in society.
