Integration of Local Wisdom in the Implementation of the Merdeka Belajar Kampus Merdeka (MBKM) Policy in The Biology Education Study Programs in Indonesia: Analysis and Evaluation
Get PDFThis study analyzes the implementation of the “Merdeka Belajar Kampus Merdeka (MBKM)” program in the Biology Education Study Program (BESP) on various campuses in Indonesia with a special focus on the integration of local wisdom. Data was collected from respondents in 44 study programs covering aspects such as campus status, accreditation, course repositioning, implementation of MBKM activities, and suggestions and recommendations for program improvement. The results of the analysis show that the majority of study programs at state campuses (75%) have repositioned the curriculum and implemented various forms of MBKM activities such as student exchanges (70.45%), internships/work practices (68.18%), and teaching assistance. The integration of local wisdom is emerging as an important aspect, with many study programs using local wisdom in academic activities and business product development, such as using traditional medicinal plants for health products. Key suggestions from respondents included the need for standardization of guidelines, financial assistance for students, periodic evaluations, and adjusting the curriculum to the needs of the times. Most study programs have ensured that MBKM activities follow the formulated Program Learning Outcomes (PLO), with 63.64% of study programs stating that they always ensure this suitability. However, there are still challenges in the process of recognizing MBKM activities into courses and integrating these activities into a thesis or final project, with 77.27% of study programs not carrying out this integration. The study concludes that although MBKM has been doing well, there is still room for improvement. There needs to be further efforts in terms of integrating local wisdom, financial support, and strengthening collaboration between educational institutions and local communities. Clear and standardized implementation of guidelines, as well as continuous evaluation, are essential to improve the effectiveness and benefits of the MBKM program
Analysis of the Effects of Tropical Fruit Extracts on the Physicochemical, Tenderness and Organoleptic Characteristics of Buffalo Meat
Get PDFBuffalo meat is an essential protein source in many regions but faces quality challenges, including oxidation, discoloration, and reduced tenderness. This study investigates the impact of soaking buffalo meat in extracts from melinjau, papaya, and pineapple on its physicochemical properties (color, protein, fat content, and tenderness) and organoleptic characteristics (color, aroma, texture, tenderness, and juiciness). Buffalo meat samples were soaked in fruit extracts for varying durations, followed by analysis of color, protein and fat content, tenderness, and sensory qualities. The results showed significant effects of soaking on color, with melinjau and papaya extracts improving lightness and reducing redness. Soaking with papaya and pineapple extracts enhanced tenderness, while melinjau extract increased juiciness. Protein content decreased slightly, but fat content was significantly reduced, particularly with papaya extract. Sensory evaluation revealed that melinjau extract produced the most favorable tenderness and juiciness, while papaya and pineapple extracts also improved tenderness. These findings suggest that tropical fruit extracts can be used to enhance buffalo meat quality by improving tenderness, reducing fat content, and extending shelf life. This natural preservation method offers a potential alternative to synthetic additives, contributing to better sensory properties and higher-quality buffalo meat products
WOMEN AND MUSLIM EDUCATION IN WEST SUMATRA, INDONESIA
Get PDFMinangkabau was known for its dominant Islamic education history especially in modern times since the beginning of the twentieth century as a number of so-called madrasah or Islamic educational reforms have been credited to several prominent figures in the region. This region also has a significant history and tradition of matriarchal and matrilineal kinship that relate to women’s position, and their contributions in the public affairs, including in the field of education. Several prominent women from the region have been named as founders of several schools for women, or journalists that campaign for women’s education. This study examines the socio-historical aspects of women and education and the women’s educational movement initiatives from the cases of few female figures such as Rahmah el-Yunusiyyah and others. From a historical perspective and qualitative library research data, this study shows the presence of local female figures in the field of education alongside their male counterparts amidst the kaum muda and kaum tua socio-religious contestation. The socio-local traditions influenced women’s presence and contribution to the public sphere, and those women not only established schools for women but also advocated women’s rights, including their rights for education through journalism and politics
CHILD GUARDIANSHIP IN INDONESIAN LEGISLATION REGULATIONS
Get PDFEvery child has the fundamental right to protection, which includes having a guardian. If the child's parents are still alive, they are automatically considered the guardians. But in certain cases where this is not possible, a court will assign another person or a governmental institution to act as the child's guardian. The laws and regulations surrounding guardianship in Indonesia are often inconsistent. This study aims to clarify the age requirements for children in need of a guardian, the procedures for appointing a guardian, as well as the duties and responsibilities of guardians according to Indonesian laws. The research also highlights areas for improvement. To achieve this, a statutory approach is adopted, with legal regulations in Indonesia on children and guardianship as the primary source of data. The findings reveal that the age requirements for children to have a guardian range from 16 to 19 years. Additionally, a court order is required for the appointment of a guardian to ensure legal validity. Additionally, the selection of a guardian needs to go through a court ruling in order to ensure legal clarity. The regulations differ from one to another, and in the process, there have been no affirmative efforts taken to expedite the process of appointing a guardian, which has the impact of children not being protected from the start. Affirmation efforts can be carried out through the involvement of village government officials and the subdistrict Religious Affairs Office for those who are Muslim. Then, regarding the duties and responsibilities of guardians, there are still differences either the guardian’s obligation to fulfil a child’s physical and spiritual needs or maintain the child’s assets. These provisions need to be combined to provide comprehensive protection for children from various aspect
