Abstract

The hydraulic ram pump is one form of green energy used to convey water by utilizing the water hammer effect. The main parameter influencing the performance of a hydraulic ram pump is the water energy source. Most researchers modify the hydraulic ram pump design based on the installation site, which limits the variation of design or operating conditions due to the complexity and geographical constraints in the field. The main contribution of this work is the development of a vertical-type hydraulic ram pump simulator that enables controlled laboratory investigation of design modifications and operating parameter optimization, overcoming the limitations of site-specific field installations. The research applies a design and experimental method. The design process begins with defining design constraints and calculating the flow based on the Bernoulli equation, flow rate, head loss, and rule-of-thumb operational conditions for hydraulic ram pumps. The results show that the flow rate significantly affects the pump efficiency. Flow rates of 0.6 L/s, 0.8 L/s, 0.9 L/s, and 1 L/s. The range pressure of P1 are 50-60 mBar, 8-90 mBar, 80-120 mBar, and 100-140 mBar.  The range pressure of P2 are 120-125 mBar, 20-40mBar, 20-40mBar, and 85-120 mBar. Therefore, the yielded average efficiencies are 5.3%, 1.6%, 3.9%, and 3.5%, respectively. The developed hydraulic ram pump simulator achieved the highest efficiency (5.3%) at a flow rate of 0.6 L/s, P1 50-60 mBar, and P2 120-125 mBar. It can be observed that an increase in drive pipe flow rate does not always correspond to an increase in efficiency. However, the efficiency is more strongly determined by the pressure generated by the water hammer.

Abstract

Abstract: The reconstruction of Indonesian legal theory, which is dominated by positivism and legal formalism, creates a gap between legal certainty and substantive justice. This dominance ignores the moral and social dynamics of society and presents the law as a tool for legitimizing power. This study uses doctrinal law research methods to analyze the synthesis of rationalism, empiricism, and pragmatism within the framework of national legal theory. The findings show that rationalism provides a structural foundation through Joseph Raz’s conception of legal authority; empiricism catalyzes harmony among Indigenous law, Islam, and the West, grounded in social realities; and pragmatism encourages flexible reforms, such as the Omnibus Law, but risks reducing democratic principles in Indonesia. New Legal Realism (NLR) is proposed as an integrative framework that combines normative, empirical, and realist analysis to produce responsive legal findings. This paper is expected to contribute to the development of dynamic legal theory through a double movement: the extraction of the universal meaning of norms, accompanied by empirical contextualization, and the emphasis on the need for interdisciplinary legal education reform and the strengthening of democratic institutions.

Abstract

This study aims to examine the potential of Lubuk Larangan as a biology learning resource to support the development of students’ environmental literacy. The study employed a Systematic Literature Review (SLR) method by analyzing scholarly articles obtained from major academic databases such as Google Scholar, Scopus-indexed journals, and national indexed journals. An initial search identified 100 relevant articles, which were then screened and evaluated using predefined inclusion and exclusion criteria, resulting in 11 articles selected for in-depth analysis. The findings indicate that Lubuk Larangan provides a meaningful contextual learning environment where students can directly explore ecological concepts such as ecosystems, biodiversity, and sustainable resource management. Integrating this local wisdom into biology learning supports the development of environmental awareness, critical thinking, and collaborative problem-solving skills. Moreover, the use of Lubuk Larangan aligns with the principles of 21st-century education that emphasize contextual, experiential, and community-based learning. This study therefore recommends integrating Lubuk Larangan into the biology curriculum as a strategy to strengthen environmental literacy and promote conservation values. Effective implementation requires collaboration among educational institutions, local communities, and government stakeholders to ensure sustainable conservation practices and meaningful environmental education in Indonesia.
