Abstract

Weeds cause significant yield loss in many agriculture crops; thus, management practices are urgently needed to alleviate losses while conserving environmental and human health. This study aimed to evaluate the allelopathic potential of Wedelia leaf and flower extracts on the germination and early growth stage of three plant species. The research was conducted using a completely randomized design experiment with two factors and four replicates. The first factor was extract sources: leaves (S1) and flowers (S2). The second factor was the concentration: control (C0) and extract concentrations of 1% (C1), 5% (C5), and 10% (C10). The extract was tested on three different plant species: soybean (Glycine max), nutsedge (Cyperus rotundus), and billygoat weed (Ageratum conyzoides). Fifty seeds of three different plants were germinated separately in Petri dishes and treated using Wedelia extracts. The allelochemicals in Wedelia leaf and flower extracts inhibited germination and induced abnormal sprouting. Wedelia leaf extract showed the most pronounced inhibitory effects and highest inhibition levels across all measured parameters. Moreover, a clear concentration-response relationship was observed, where increased extract concentration increased the degree of inhibition. These findings contribute to the development of bioherbicides and can help reduce the use of synthetic herbicides for more sustainable agriculture. Keywords: Ageratum conyzoides, bioherbicide, Cyperus rotundus, Glycine max, weed control

Abstract

At SMP Negeri 16 Surabaya, a service learning (SL) project tackled the issue of paper waste by engaging 25 Adiwiyata team students in environmental socialization and creative practices, supported by the Surabaya City Environmental Agency and guided by PPG students from the State University of Surabaya. The project involved stages such as problem identification, planning, and service implementation, culminating in the creation of a 3-dimensional map of Indonesia from paper waste. This hands-on approach allowed students to apply theoretical knowledge while developing social skills and responsibility. The activity was successful, with enthusiastic student participation and the production of an impactful creative product. Background. In schools, paper waste is a worrying problem. Every day, paper is used for purposes, from student assignments, duplication of materials, to school administration. This accumulation of paper use is not balanced with an effective waste management system, so that a lot of waste paper is wasted without being reused. This condition not only contributes to the accumulation of waste in schools, but also negatively impacts the environment at large. Purpose. This activity is carried out with a service learning (SL) approach that integrates student learning experiences with services to the community. Through service learning (SL), students not only apply the theoretical knowledge gained in lectures, but also develop social skills, empathy, and responsibility. In this activity, students are directly involved in projects that are beneficial to the community, one of which is environmental socialization and paper waste creation practices for students (adiwiyata team) at SMP Negeri 16 Surabaya. Method. This activity is carried out through stages in the service learning (SL) approach, including problem identification and planning, classroom preparation and learning, service implementation, reflection, demonstration and evaluation, and sustainable development. Results. This activity was attended by 25 students of SMP Negeri 16 Surabaya with socialization activities supported by the Surabaya City Environmental Agency and creative practices guided by PPG students from the State University of Surabaya. This activity produces a creation product from paper waste in the form of a 3-dimensional map of islands in Indonesia. Conclusion. The activities carried out have been carried out well by showing students who are enthusiastic in participating in the activity, shown by the students who attended in accordance with the planned invitation and producing creative products.

Abstract

The principle of equality before the law is one of the main pillars of the rule of law, guaranteeing equal treatment for all citizens without discrimination. However, in practice, this principle is often not optimally implemented, especially for minority groups who are in vulnerable social, political, and legal positions. This article analyzes the forms of legal discrimination experienced by minority groups in the application of the principle of equality before the law and identifies the factors that cause this inequality. This study uses a normative legal research method with a legislative, conceptual, and case-based approach. The results show that legal discrimination against minority groups occurs in both the substance of the law, the structure of law enforcement, and the legal culture of society. Factors such as bias among law enforcement officials, weaknesses in legal protection, and the influence of social stigma and identity politics are the main obstacles to the realization of substantive legal equality. This article argues that the principle of equality before the law is not sufficient in itself; it must be realized through a substantive approach that protects human rights and ensures justice for minority groups.

Abstract

Background:The Constitutional Court plays a strategic role in Indonesia's constitutional system as the guardian of the constitution, authorized to review laws against the 1945 Constitution. In practice, several Constitutional Court decisions demonstrate a tendency toward judicial activism, where judges not only interpret legal norms but also expand or create new ones. This phenomenon has given rise to debate regarding the limits of the Constitutional Court's authority within the framework of the separation of powers and its implications for the development of national law. Aims:This study aims to analyze the role of the Constitutional Court in implementing judicial activism and assess the effectiveness of this practice from a progressive legal perspective. Methods:This study uses a normative legal research approach with a statute approach, a case approach, and a conceptual approach. The research data was obtained through a literature review, which included primary legal materials in the form of legislation and Constitutional Court decisions, as well as secondary legal materials in the form of books, scientific journals, and academic literature. Data analysis was conducted qualitatively through data reduction, data presentation, and conclusion drawing. Result:The research findings indicate that the Constitutional Court has implemented judicial activism in several of its decisions, reflected in decisions that are corrective, protective, and adaptive to social dynamics. This practice is evident in several important decisions that broaden the interpretation of legal norms to protect citizens' constitutional rights and fill legal gaps in the legal system. Conclusion:From a progressive legal perspective, the practice of judicial activism can be understood as the Constitutional Court's effort to achieve substantive justice in the Indonesian legal system. However, the implementation of this practice must adhere to the principle of separation of powers to avoid shifting authority between the judiciary and the legislature in a constitutional democratic system.
