Abstract

The biodiversity crisis in the anthropocene era demands a reconstruction of the environmental law paradigm that goes beyond anthropocentric logic. This study comparatively examines the biodiversity protection paradigm within a legal-ethical-teleological framework by integrating the positive legal norms of Law No. 32/2009 concerning Environmental Protection and Management with the principles of environmental fiqh (fiqh al-bi’ah). This research method uses a normative juridical approach with statutory, conceptual, and comparative approaches.The results of the research indicate that there are points of agreement and disparities between Law 32/2009 and the MUI Fatwa No. 4/2014 both emphasize the importance of protecting ecosystems for the sake of the balance of life, but with different approaches. The Environmental Management and Management Law (UU PPLH) is normative-instrumental (anthropocentric), while the fatwa emphasizes the moral-religious obligation to preserve living creatures. This study's novel approach is a tridimensional legal, ethical, and teleological framework that synergizes positive legal norms with Islamic ethical values and the objectives of maqashid (environmental stewardship). With this research, the concept of maqashid sharia, specifically hifa al-bi'ah (environmental preservation), is proposed as a normative-teleological foundation for reconstructing national environmental law with ecological justice

Abstract

Bioethanol is a renewable energy that has the potential to replace fuel oil with a high octane value. A common problem experienced in the process of making bioethanol is the difficulty of obtaining pure ethanol levels. So the purification process is an important factor in producing bioethanol which can function as fuel. The distillation process aims to separate ethanol from the ethanol-water mixture. The boiling point of ethanol is 78ºC and the boiling point of water is 100ºC so that by heating to a temperature of 78ºC using the distillation method, ethanol can be separated from the ethanol-water mixture. In this research, a distillation device has been successfully designed which consists of a heater, boiler and heat exchanger. The shell and tube type heat exchanger is designed with a capacity of 2 liters. The tube side uses 20 copper pipes with a diameter of 1/4 in, a thickness of 0.5 mm, a length of 400 mm, and a pitch distance of 13 mm. On the shell side, a 3 in diameter PVC pipe with a length of 500 mm is used. Capable of transferring heat with effectiveness reaching 89% with ethanol content of 92%.

Abstract

This research aims to evaluate the effect of variations in fiber type and volume fraction of torch ginger (kecombrang) stem fibers on the impact toughness of epoxy resin-based composite materials. The method used in the composite fabrication process was the Hand Lay-Up technique. Based on the test results using the Charpy Impact method, the first specimen—with a volume fraction composition of 70% torch ginger stem fiber and 30% epoxy resin—demonstrated the highest energy absorption capacity at 11.513 Joules. The second specimen, consisting of 65% torch ginger stem fiber and 35% epoxy resin, produced an energy absorption of 10.294 Joules, slightly lower than the first specimen. Meanwhile, the third specimen recorded the lowest energy absorption at 9.511 Joules with a composition of 60% torch ginger stem fiber and 40% epoxy resin, indicating that this specimen possesses the lowest impact toughness among the three tested configurations.
