Abstract

Tanah merupakan salah satu kekayaan negara Indonesia yang menjadi modal dasar agar kehidupan masyarakat dapat adil dan makmur, sehingga pemanfaatannya harus berdasarkan prinsip-prinsip yang tumbuh dan berkembang dalam kehidupan masyarakat Indonesia. Penelitian tesis ini menggunakan Penelitian Hukum Normatif yang menganalisis tentang pembatalan Perjanjian Sewa-Sewa Tanah yang dialihkan kepada pihak ketiga. Rumusan masalah dalam penelitian skripsi ini adalah apa akibat hukum yang timbul jika pembatalan dialihkan kepada pihak ketiga? dan bagaimana pembatalan Perjanjian Sewa-Sewa Tanah dialihkan kepada pihak ketiga berdasarkan Putusan Mahkamah Agung Nomor: 1616 K/PDT/2018? Sebagai alat analisis untuk membahas hal tersebut digunakan Teori Perjanjian dan Teori Kepastian Hukum, serta menggunakan Pendekatan Statuta, Pendekatan Analitik dan Konseptual, Pendekatan Kasus dan Pendekatan Komparatif. Kesimpulan dari penelitian ini adalah akibat hukum yang timbul dari pembatalan yang dialihkan kepada pihak ketiga yaitu Perjanjian yang menggunakan warga negara Indonesia sebagai Nominee adalah penyelundupan yang sah karena substansinya bertentangan dengan Undang-Undang Pokok Agraria (UUPA), dimana secara substansi ketentuan dalam Pasal 9, Pasal 21, dan Pasal 26 ayat (2) UUPA tidak dapat menyimpang. Pada hakekatnya perjanjian nominee bertujuan untuk mengalihkan hak milik atas tanah kepada pihak asing, sehingga keberadaan akta otentik perjanjian nominee sebagai alat bukti menjadi batal demi hukum

Abstract

The unavailability of teaching materials that can support mathematical problem-solving abilities and are integrated with Islamic teaching values makes it difficult for SMP IT educators to hone students' mathematical problem-solving abilities and difficulties in instilling Islamic values in students. One solution that educators can use in learning is to use e-modules. E-module is a teaching material that has the characteristics of independent learning principles. This research aims to see the effectiveness of using mathematics e-modules that are integrated with Islamic values in facilitating students' mathematical problem-solving abilities. This type of research is pre-experimental research and the research design is one group pre-test-post test design. The sampling method is purposive sampling, where one class is taken directly from the population as a research sample. The subjects of this research were 24 students in class VIII.1 at SMP IT Qurrata A'yun Batusangkar. The effectiveness of the mathematics e-module can be seen from the comparison of the results of the pre-test and post-test of students' mathematical problem-solving abilities. The final results of the student's mathematical problem-solving ability test obtained were 57% of the total maximum score, while the results of the student's initial mathematical problem-solving ability test were only 22% of the maximum score. Because 57%>22%, these results indicate that the use of Islamic integrated mathematics e-modules is effective in facilitating students' mathematical problem-solving abilities.

Abstract

This research aims to develop a teaching module based on RME that is valid, practical, and effective for class VII SMP, with a focus on improving the ability to solve problems with mathematical students. We developed the modules by considering the local context and culture, adhering to RME measures, and emphasizing the use of relevant and conceivable situations for students. We utilized the Plomp development model, which encompasses the stages of investigation, creation, and evaluation. We tested the prototype and assessment of this teaching module on participants enrolled in class VII at SMP N 1 Ranah Batahan. The research results demonstrate that the developed teaching modules have high validity (89.33%), practicality (89.60%), and proven effectiveness, as evidenced by an average score of 85.50% among the test study students.  In addition to enhancing the mathematical skills of students, the RME approach also enhances the study of IPAS (Natural and Social Sciences). The development of problem-solving and critical thinking skills through this module enhances students' understanding of natural and social phenomena. Therefore, this teaching module not only promotes mathematical achievement but also fosters integrative and holistic learning within the framework of IPAS.
