This study aimed to develop and evaluate Augmented Reality (AR)-based learning media to enhance students’ cognitive abilities at State Vocational High School (SMK Negeri) 2 Pati, particularly in the subject of Computer Networking and the Internet. The research was motivated by low student achievement in meeting the Minimum Mastery Criteria (KKTP), which was primarily attributed to the continued reliance on traditional teaching methods and low student motivation. A research and development (R&D) approach was employed using the ADDIE model. The resulting AR media is an Android application that integrates text, audio, images, animations, interactive 3D objects, and simulations, and is in accordance with the Merdeka Curriculum. Expert evaluations showed a very high level of feasibility, with ratings of 94% from a subject matter expert and 91% from a media expert. These results were further supported by Aiken’s V index, which indicated very high validity for the material (0.921) and high validity for the media (0.881). A practicality test was conducted, revealing a high level of effectiveness, with a 94% approval rating from both teachers and students. Moreover, a pretest–posttest control group design demonstrated significant progress in learning outcomes. The experimental group achieved an average post-test score of 83.75, significantly higher than the control group’s 73.60. Based on the N-Gain test, the experimental group achieved an average gain of 65.52% (moderately effective), whereas the control group achieved only 38.75% (ineffective). This study contributes to the theories of learning transfer, connectivism, and heutagogy, and offers practical implications for vocational education in adopting innovative technologies. 
 

This study aims to determine the effect of jumping and throwing park games on improving basic motor skills of junior high school students. The research method used is an experiment with a pretest-posttest control group design. The sample consisted of two classes, each consisting of 30 students, divided into experimental and control groups. The instrument used refers to the Test of Gross Motor Development (TGMD-2) to measure jumping, throwing, and balance abilities. The results of the analysis showed that there was a significant increase in the post-test results of the experimental group compared to the control group (p = 0.000). Jumping and throwing park games have proven effective in integrating locomotor and manipulative movements through a fun play approach, thereby increasing students’ motivation and active participation in physical education learning. These findings indicate that learning media designed according to the characteristics of student development can make a real contribution to improving motor skills. Therefore, the use of this media is recommended as an alternative learning strategy that is educational and fun in the school environment. 

The uniqueness of primogeniture in traditional inheritance systems is urgent to examine, as it reflects enduring gendered power structures that persist amid legal modernization and evolving social norms. This research analyzes the uniqueness and resilience of the primogeniture inheritance system in traditional communities, particularly in Ratenggaro Traditional Village, Indonesia. It is situated within the legal pluralism context of Indonesia and the human rights-based critique of customary laws that prioritize male heirs. The study is urgent because modernization challenges traditional norms, demanding a reevaluation of gender equity in inheritance. Using a descriptive qualitative method with in-depth interviews and participant observation, this study finds that primogeniture governs not only material assets but also spiritual roles and kinship status. Despite modern pressure, elders uphold it as a symbol of identity and harmony. A unique finding is that although women do not inherit property, they are symbolically acknowledged through ritual practices involving gifts such as woven cloth and livestock. This study offers novelty by providing a legal-anthropological analysis of primogeniture in a remote indigenous context, contributing to discussions on legal pluralism, gender justice, and cultural sustainability. It suggests the need for dialogical reform that harmonizes adat law with constitutional equality.

Leguminous plants are plants with high protein and nutrient content, especially the protein content. Leguminous plants can grow anywhere but these plants have not been widely utilised by farmers. Some information related to leguminous plants is expected to help farmers overcome feed in the dry season. The information was obtained by reading and analysing literature and data from various research libraries that have been published in accredited journals. Tree legumes include indigofera, lamtoro, turi, gamal, and kaliandra. Indigofera plants have a crude protein content of 29.16%, while lamtoro, turi, gamal, kaliandra and Moringa are 23.8%; 31.29%; 22.6%; 25%; and 25.77% respectively. The nutrient content is supported by high productivity, where the production of indigofera, lamtoro, turi, gamal, and kaliandra can reach 4.096 tonnesBK/ha/year; 8.1 tonnes/ha/year; 2-3 tonnes/ha/harvest; 62.76 tonnes/ha/year; and 2-3 tonnes/ha/year, respectively. Despite its potential as animal feed, the plant needs further processing to reduce the anti-nutrients contained and increase its palatability so that livestock productivity increases.
