Abstract

Senyawa oksida logam berstruktur Aurivillius Pb2Bi3Ti3,5W0,5O15 (PBTW) telah disintesis pada kisaran suhu 900 - 950 oC dengan metode reaksi fasa padat. Difraktogram hasil analisis XRD dibandingkan dengan database PDF (Powder Diffraction File) menggunakan Program Phasanx dan penelusuran difraksi menggunakan program Rietica dengan metode Rietveld. Hasil penelitian menunjukkan bahwa parameter sel oksida Aurivillius PBTW yaitu a = 5,2453 Å; b = 5,5363 Å; c = 41,6342 Å dengan grup ruang A21am dan sistem kristal ortorombik. Berdasarkan hasil pengukuran sifat feroelektrik didapatkan bahwa senyawa hasil sintesis dari oksida logam berstruktur Aurivillius tipe PBTW menunjukkan adanya pola histerisis. Nilai polarisasi remanen Pr(+) oksida Aurivillius tipe PBTW sebesar 12,4 C/cm2, dengan nilai Kef dan kapansitansinya 423.132 dan 489,788 nF.

Abstract

Based on the description above, the objectives of this study are: to find out and explain wills without a Notary Deed in view of the KHI and the Civil Code; To find out and explain the similarities and differences of wills without a Notary Deed in view of the KHI and the Civil Code. The research approach used is normative juridical.The results obtained in this study are the legal consequences of wills without a notary deed, making the will prone to lawsuits from interested parties because the evidence is not strong enough and there is no legal certainty. By law, if a will is made without a notary deed or a testament under hand, the will cannot provide a guarantee of legal certainty because it can be canceled unilaterally. According to the Civil Code, wills can be revoked and can be canceled or canceled. As for the revocation of a will according to the KHI, among others, is regulated in Article 199. There are three ways to revoke a will according to the Civil Code, namely explicit revocation, secret revocation and revocation due to exile.Keywords: Legal Consequences, will, notary deed, compilation of Islamic law, civil law

Abstract

This paper discusses the implementation of mediation in the Indonesian Worker (TKI) divorce process at Religious Court of Ponorogo. Recently, mediation has become an alternative in resolving cases outside the litigation path. The high number of divorce cases is increasingly concerning, for example in 2013, Religious Court of Ponorogo experienced an increase of 1,781 cases from 1,668 cases in 2012. After six years, the divorce rate is still quite high. Data for 2019 for the period of January-August, 422 cases of divorce, and 1,044 cases of divorce doubled. The cause of the divorce is mostly due to economic factors, the continuous bickering until these factors leave one party. Interestingly, cases of divorce include a married couple who work as migrant workers. Mediation as an important instrument in divorce prevention, as well as part of the court process, is the starting point for handling divorce for migrant workers. However, the existence of the parties because they work as migrant workers certainly has implications for the implementation of mediation. The approach used is a normative juridical approach, namely an approach based on the provisions of Islamic law and statutory regulations. As a result, TKI mediation in Religious Court of Ponorogo in 2013 reached 104 cases, all of which ended in failure. In addition, out of 104 cases, 81 cases were decided one after another because one party never attended and was abroad.

Abstract

One of the potentials that must be developed and formed in higher education is critical thinking. Critical thinking is an organized mental process and plays a role in the process of making decisions to solve problems. Critical thinking includes the activities of analyzing and interpreting data in scientific discovery activities. To develop students' critical thinking skills, learning innovations need to be implemented. The aim of this research is to find out how the critical thinking attitudes of IPR students develop in learning Indonesian language courses. This research is classroom action research using a design developed by Kemmis and MC Taggart which consists of three stages, namely the planning stage, the treatment and observation stage, and the reflection stage. The results of this research show that the development of critical thinking of HKI students in the Indonesian language course has succeeded in improving their thinking skills with a score of 23 in the pre-action stage, cycle I increased to 27.7 and cycle II increased to 36.6.
