Abstract

This research presented a novel approach to optimize powered landing control on reusable rockets by using Softmax Double Deep Q-Networks (DDQN). We combined the advantages of Double DQN with Softmax exploration and curriculum learning to achieve precise and efficient landing control. Through extensive experiments in a specially developed 2D simulation environment, our method achieves improved landing accuracy by 37% (reduced final position error from 2.4 m to 1.5 m), better fuel efficiency by 28% (reduced average fuel consumption from 850 kg to 612 kg per landing), and improved adaptability to initial conditions (improved successful landing rate from 76% to 94% across a wide range of altitudes and initial orientations) compared to traditional PID control methods. The results showed that the curriculum learning method significantly outperformed the non-curriculum approach, achieving 27% higher average awards (11.97 vs. 8.61) and 60% better performance consistency as measured by standard deviation (0.92 vs. 2.29). Both Softmax and ε-greedy exploration strategies proved effective with curriculum learning, with ε-greedy DDQN achieving the highest average award of 11.97. This approach allows for higher precision rocket landings while reducing operational costs through.

Abstract

This study critically examines Atharyanshah Pueri's article on the comparison of Islamic contract law and Indonesian law, against the background of the importance of high methodological standards in the study of comparative law, especially in the context of Indonesian legal pluralism. The approach of this study uses normative legal techniques and critical analysis, with a comparative methodology evaluation framework based on contemporary comparative legal theory. Meta-analysis techniques were used to assess the methodological framework, quality of argumentation, and engagement with primary sources and relevant literature. The study found that Puneri's article has significant methodological weaknesses, such as the absence of a clear comparative framework, limitations in the use of primary sources, lack of contextualization, and superficial substance analysis of both Islamic contract law and Indonesian law. The article also fails to identify the comparative tertiums that are essential for comparative studies. These weaknesses demonstrate the urgency of developing a more rigorous comparative legal research methodology, including the application of functional theoretical frameworks, the integration of case studies, and contextual analysis that includes socio-economic dynamics. This constructive academic criticism is expected to spur the improvement of the quality of legal research in Indonesia with international academic standards.

Abstract

Rasulullah is a leader of the ummah throughout the world, where he is a role model in worship, social interaction with others or in doing charity, because everything that originates from Rasulullah is sunnah in accordance with what was conveyed by hadith scholars, which means "everything that is attributed to the Prophet Muhammad SAW is sunnah, whether in the form of words, deeds, taqrir (rule of law), khuluqiyyah (personality) and khalqiyyah (physical) of him. Because something that comes from the Messenger of Allah is essentially from Allah, which in this case is emphasized which means "And he did not speak from his desires, but rather a revelation that was revealed." One of the things that is no less important to study is his principle of economic independence in living his life, so that we can take intifa' (benefits) from him, to use as a principle in living this life and which is no less important so that we always follow the sunnah in aspects of our life.
