Abstract

This research aims to determine the influence of the Team Assisted Individualization (TAI) Cooperative Learning Model on Student Learning Outcomes in Theme 8 Our Friend's Environment Class V of State Elementary School 155701 Pahieme 2 Learning Year 2023/2024. The research method used is an experimental method with a quantitative research type. The total research sample was 30 students based on purposive sampling technique. To determine students' initial abilities, the research conducted a Pre Test with an average score of 52.63 which was in the poor category. The results of the Post Test have improved from the Pre Test results given previously with the students' average score reaching 75.53 in the good category. It can be said that the level of success in student learning outcomes has increased as evidenced by the results of the correlation coefficient test calculation, which obtained r_count ≥ r_tabel with results of 0.766 ≥ 0.361. Next, hypothesis testing is comparing the t_count≥ t_table values. The obtained value of t_count = 6.311 while t_table = 1.697. Because t_count ≤ t_table (6.311 ≥ 1.697) then H_a is accepted and H_o is rejected. Through the t-test, it can be concluded that there is a significant positive influence between the Team Assisted Individualization type cooperative learning model on student learning outcomes.

Abstract

Tulisan ini berusaha untuk merumuskan kembali bagaimana nilai-nilai vital yaitu budaya malu (shame culture), budaya bersalah (guilt culture) yang mampu memengaruhi tingkat kesadaran hukum demi mencapai kepentingan bersama (bonum commune). Hal ini penting untuk dilakukan karena hakikat budaya malu, budaya bersalah dan kesadaran hukum sebagai alat pengendali tingkah laku telah mengalami pergeseran makna dari makna aslinya. Tak bisa dipungkiri mahasiswa hukum sering tergoda oleh sejumlah gaya hidup penegak hukum yang bergelimang kekuasaan dan uang yang bertentangan dengan tujuan perjuangan hukum yaitu kepentingan bersama (bonum commune). Pendekatan etika Thomas Aquinas dan pendekatan antropologi digunakan penulis untuk menggali data tentang manusia dengan kebudayaannya dan manusia dengan hukum dan tatanan kehidupannya. Teori kesadaran hukum Soerjono Soekanto digunakan sebagai parameter untuk menguji bagaimana nilai dalam budaya malu, budaya bersalah mendorong tingkat kesadaran hukum demi kepentingan kepentingan bersama (bonum commune). Kesimpulan dari studi ini adalah budaya malu, budaya bersalah dapat mendorong seseorang untuk memiliki kesadaran hukum: (1) pengetahuan hukum (law awareness), (2) pemahaman hukum (law acquaintance), (3) sikap hukum (legal attitude), dan (4) pola perilaku hukum (legal behavior) untuk mencapai kepentingan umum (bonum commune).

Abstract

Fiat justitia ruat caelum, artinya hendaklah keadilan ditegakkan walaupun langit akan runtuh. Kalimat yang diucapkaan oleh Lucius Calpurnius Piso Caesoninus (43 SM) akan bisa terwujud bila peradilan memiliki salah satunya penegak hukum yaitu hakim yang betul-betul punya kualitas dan integritas yang handal. Berbagai kasus suap kepada hakim telah mencoreng wajah peradilan di Indonesia dan pada gilirannya menurunkan tingkat kepercayaan masyarakat terhadap aparat penegak hukum. Pendidikan tinggi hukum mendapat sorotan tajam, sebab seakan-akan tidak mampu menjawab kebutuhan akan lahirnya penegak hukum yang memiliki integritas dan kepribadian yang kokoh. Tulisan ini berupaya mengkaji faktor-faktor yang mempengaruhi putusan hakim berdasarkan tingkat kesadaran moral, sikap advocatus diaboli dan bagaimanakah hakim ideal yang dibutuhkan sebagai benteng keadilan dalam rangka mengejawantahkan supremasi hukum dengan tiga prinsip pokok yaitu (1) keadilan (gerechtigheit), (2) kepastian (rechsecherheit), dan (3) kemanfaatan (zwachmatigheit). Negara Indonesia adalah negara hukum, di mana hukum dapat dilaksanakan dan ditegakkan. Hukum harus menjadi panglima di negara ini, maka hukum perlu ditegakkan sehingga supremasi hukum mempunyai kedudukan tertinggi (the supreme state of the law) sebagai bagian dari rule of law dan bukan the rule of the political man. Yurisprudensi Schubert meyakini, bahwa sikap hakim merupakan faktor dalam pengambilan putusan yang lebih menentukan daripada yang lain. Ia menepiskan faktor-faktor lain, seperti pendidikan, tradisi yang diajarkan dan cara penalaran. Hakim bersikap begini atau begitu, karena ia menjatuhkan pilihan terhadap sesuatu yang diyakininya lebih daripada yang lain
