Abstract

Istilah Gono Gini yang dikenal oleh budaya atau adat yang berkembang di Indonesia adalah harta bersama, Harta Gono Gini merupakan hasil harta bersama yang dimiliki oleh pasangan yang sudah menikah. Kompilasi Hukum Islam Pasal 85 menegaskan “adanya harta bersama dalam perkawinan itu tidak menutup kemugkinan adanya harta milik masing-masing suami atau isteri” dan Pasal 86 sebagai berikut: a) Pada dasarnya tidak ada percampuran antara harta suami dan harta isteri karena perkawinan. b) Harta isteri tetap menjadi hak isteri dan dikuasai penuh olehnya, demikian juga harta suami tetap menjadi hak suami dan dikuasai penuh olehnya. Pasal 97 Janda atau duda cerai masing-masing berhak seperdua dari harta bersama sepanjang tidak ditentukan lain dalam perjanjian perkawinan. Sedangkan di dalam UUD No 1 Tahun 1974 tentang perkawinan Pasal 35 di atur. a. Harta benda yang diperoleh selama perkawinan, menjadi harta bersama. b. Harta bawaan dan masing-masing suami dan isteri dan harta benda yang diperoleh masing-masing sebagai hadiah atau warisan, adalah dibawah penguasaan masing-masing sepanjang para pihak tidak menentukan lain. Pasal 37 Undang-Undang Perkawinan menyatakan bahwa bila perkawinan putus karena perceraian harta bersama diatur menurut hukumnya masing-masing. Jika dicermati Kompilasi Hukum Islam (KHI) Pasal 85 dan 97 tentang Harta Bersama tidak memberikan keseragaman Hukum Islam dalam penyelesaian Harta bersama apabila terjadi perceraian. lalu, UU Perkawinan No 1 Tahun 1974 Pasal 37, Jika dicermati juga maka Pasal 37 Undang-Undang Perkawinan dan penjelasannya, tidak memberikan keseragaman hukum positif tentang bagaimana penyelesaian harta bersama apabila terjadi perceraian, hal ini tentu menjadi problem sosial hukum. jika penyelsaian dan penetapan Harta bersama tersebut tidak efektif dan adil dalam pembagiannya. Maka, rentan konflik antara pasangan suami istri kemungkinan bisa terjadi.

Abstract

Elections are a democratic party for the people as the holder of the highest sovereignty, namely electing members of the DPR, DPD, president, and vice president by the 1945 Constitution article 22E paragraph "general elections are carried out directly, publicly, freely, secretly, honestly and fairly every five once a year." However, due to recent issues saying that the 2024 election will be postponed, which was proposed by several political party leaders and one of President Joko Widodo's ministers for reasons of maintaining national economic stability, the author tries to divert research on the issue of postponing elections from maintaining financial stability to the realm of state administration and constitution. The author uses qualitative research methods because the data source and results of this research are from library research in the form of descriptions of words. In this research, secondary data sources are used where data sources include books, articles, and journals. Data collection techniques are generally carried out by looking for data sources so that this research is carried out only based on written works, including research results that have been published, and that still need to be published. With the discussions and the results of the research, the author can conclude that if the issue of postponing the election is implemented, then it is unconstitutional or a violation of the Indonesian constitution and state administration; if this discourse is implemented by the government unilaterally without considering the will and opinion of the people.

Abstract

The phenomenon of domestic violence (DV) against online gambling perpetrators is increasingly becoming a concern in the social dynamics of modern society. Online gambling not only has an impact on the personalals involved, but also has serious implications for family stability, including increasing the potential for conflict and domestic violence. This study aims to analyze this phenomenon through the perspective of fiqh siyasah law in order to understand how Islam views and responds to this problem in the context of Islamic politics and government. The research method used is a qualitative approach with library research, where data is obtained from classical and contemporary literature in the fields of fiqh, siyasah syar'iyyah, and laws and regulations related to domestic violence and gambling. The results of the study show that fiqh siyasah has legal instruments and policies that can be used to overcome the negative impacts of online gambling on personalals and families. From an Islamic perspective, gambling is prohibited because it damages the social, economic, and moral order of society. Therefore, the state has a strategic role in protecting families from the impacts of online gambling by implementing preventive and repressive policies in accordance with the principles of siyasah syar'iyyah. The conclusion of this study confirms that domestic violence due to online gambling is a social problem that needs serious attention from the aspect of Islamic law. Fiqh siyasah can be the basis for formulating policies that not only aim to prosecute gambling perpetrators, but also provide protection to families and build a legal system that is more responsive to this problem.
