Abstract

Analisis Structural Equation Modeling (SEM) sering diaplikasikan pada permasalahan sosial yang membutuhkan model yang relatif kompleks. Pendugaan parameter pada analisis SEM membutuhkan beberapa asumsi penting seperti ukuran sampel minimal 10 kali banyaknya indikator dan data harus berdistribusi normal. Pada prakteknya tidak mudah untuk memenuhi asumsi tersebut. Dalam perkembangannya terdapat sebuah metode SEM yang tidak membutuhkan asumsi tersebut yang dikenal dengan metode analisis Partial Least Square (PLS).Metode ini merupakan analisis SEM berbasis varian atau dikenal dengan SEM-PLS. Pendugaan parameter pada metode ini tidak membutuhkan ukuran sampel yang besar dan data tidak harus berdistribusi normal. Pada penelitian ini akan ditunjukkan perbandingan analisis data menggunakan metode SEM-PLS dengan metode CB-SEM. Perbandingan analisis data menggunakan data serdos yang berupa 4 variabel laten dan 24 variabel indikator yang sebelumnya sudah dianalisis menggunakan metode analisis CB-SEM dengan data ditransformasi ke z-score untuk memenuhi asumsi. Pada penelitian ini digunakan tiga macam ukuran sampel yaitu 35,55, dan 75yang diambil dari parent sample sebanyak160kemudian dilakukan tahap Bootstrapping sebanyak 50 kali. Tahap tersebut dilakukan padasetiap ukuran sampel untuk mengetahui seberapa minim ukuran sampel pada metode SEM-PLS yang representatif terhadap sample parent. Hasil penelitian menunjukkan bahwa ukuran sampel yang digunakan pada metode analisis SEM-PLS adalah sebanyak 55. Nilai R2 pada ukuran sampel 55 sama baik dengan nilai R2 pada parent sample dengan data tidak ditransformasi ke z-score sebagaimana metode CB-SEM.

Abstract

Among the sources of Islamic law which is still disputed by Scholars argument is maslahah.  Some scholars reject it, but most agree to make maslahah as one of the sources of Islamic law in matters of ijtihad. Imam Malik considered as a Pioneer Scholar who makes maslahah as one source of his law ijtihad. His view was followed by the other Scholars, one of whom is Najm al-Din al-Tufi, acleric' Hambali.  However, the two leaders of thought are not the same, even in certain cases the difference is very sharp, although in certain parts have in common. In the view of Malik, maslahah serve as a source of  Islamic law in matters which are not discussed formally by nas and ijma ', but must not conflict with the spirit of the passage as a whole. In contrast, al-Tufi used maslahah both in matters discussed by nas/ijma’ or not. As for the area of applying maslahah, both agree that maslahah is only used in the matter of mu'amalah.

Abstract

Mahfud MD states that the Pancasila State is a constitutional state and is final, even in terms of religious/fiqh law can be declared valid and correct. The results of the ijtihad of the ulama of ushul fiqh also mentioned that the choice of national law based on the Pancasila and the 1945 Constitution of the Republic of Indonesia was the right choice and was recognized syara'. Indonesia's legal state also accepts the spiritual value of religious law. Written law and all procedural provisions (rechtsstaaf) are accepted but must be put in order to uphold justice (the rule of law). Written provisions that prevent justice can be abandoned. This is confirmed in the provisions of Article 24 paragraph (1) of the 1945 Constitution which states that the function of the judicial authority is to enforce law and justice, and Article 28D paragraph (1) concerning the right to obtain legal certainty and Article 28H that the law must be built on the basis of justice benefits. Jurisprudence law with national law has the same substance in maintaining and encouraging the development of a legal system based on social justice and public benefit (al-manfa'ah al-ammah) as has also been voiced and championed by the founders of the state when they are compiling the state ideology, namely Pancasila. Those who are predominantly Muslim have an open attitude to respect and accommodate the interests of other faith groups and religions. Abdurrahman Wahid also emphasized that the founders of the nation (such as Ki Bagus Hadikusumo, Abdul Wahid Hasyim, Kahar Mudzakkar, Agus Salim, and Ahmad Subardjo) who were experts in the field of Jurisprudence had absorbed and adopted the principles and objectives of fiqh law that had a value of justice, benefit, humanity and shura in the Pancasila state system.

Abstract

Pawn is the right to a movable item that is attached to a person for assistance in the form of giving debt to another person. Submission of the movable goods by the person who owes the party giving the debt, is given as collateral. If in the future the debtor is defaulted, does not repay the debt when it is due, the collateral can be auctioned. Pawnshops based on the Civil Code Article 1150 are pocketing official permission to manage, assist, and develop all forms of financial activities by giving injections of funds to people in the form of financing. Auth (main tasks and functions) of pawning is protecting, fostering, and providing protection in the form of loan funds with the intent and purpose so that people are not caught up in various offers and financial assistance by non-formal financial institutions that relatively utilize the community, "strangling" with interest very high. Based on the analysis of the author's research, there are many non-formal financial institutions that provide loans with very high interest rates, this pattern of loans weighs heavily on society. This action is contrary to the law which aims to prosper society. The legal basis for shari'ah mortgage is to refer to the values ​​or norms contained in the DSN-MUI fatwa No. 25 / DSN-MUI / III / 2002 dated June 26, 2002 which confirms that it is permissible to borrow money by pawning goods as collateral for debt. However, at the perfective level of institutional governance, it is based on Government Regulation No. 10 of 1990 which was ratified on April 10, 1990.

Abstract

This paper discusses the corporate crime of human trafficking. The background used is the assessment that classifies Indonesia in third place for the handling of human trafficking by the international community. The word “Hero Exchange” may often be heard, they are the workers from Indonesia who often become victims of Human Trafficking, victims sometimes traded not only for the purpose of prostitution or other forms of sexual exploitation, but also includes other forms of exploitation, such as forced labor or services, slavery or practices similar to slavery. Various government policies are made concerning the protection of women and children, basically made ​​relatively comprehensive policies, ranging from Basic Act 1945 and the rules below. However many government policies in tackling this problem is not followed by real action in the field and it can be concluded, the legal protection of women and children victims of human trafficking is still felt less effective. This is evident from the very rarity of severe criminal imposed by the judge against traffickers. The absence of compensation in the form of sanctions against traffickers also add to the sense of injustice padakorban trafficking who have suffered both physically, mentally, and economically.

Abstract

Ralf Dahrendorf's conflict theory states that the structural changes can be classified on the basis of their extremities and based on their abrupt or unexpected levels. In this case Ralf Dahrendorf admits that his theory of emphasis on conflict and social change is a one-sided perspective of social reality. This is because although the theory of structural functionalism and conflict theory is perceived by Ralf Dahrendorf as a valid perspective in approaching social reality, it includes only a part of the social reality that should be. Both theories are incomplete when used separately, and therefore should be used together, in order to obtain a complete picture of social reality. As an example of case studies, the intra-religious authoritative conflict occurring in Sampang between the Sunni and Shiite schools is a flow rush that has reduced social harmonization among the Sampang and Madurese communities in general, causing intense social tensions. Sociologically, the existence of ulema among the Madurese is not only regarded as a religious elite, but also as a non-formal leader by the Madurese people who are considered to have social authority to determine life and community life.
