Christian religious education is an important aspect in the formation of character and the development of children. In this context, teacher creativity and the role of parents play a significant role in increasing children's interest in learning through Christian religious education. However, there are challenges in terms of a lack of understanding of the importance of creativity, a lack of creative teaching methods, and suboptimal involvement between teachers and parents. Therefore, this study aims to analyze the role of teacher and parent creativity in increasing children's interest in learning through Christian religious education. Through a qualitative approach and data analysis, this study identified existing problems and provided workable solutions. The results of the study show that a deep understanding of the importance of creativity, the use of creative teaching methods, and the active involvement of teachers and parents can encourage children's interest in learning in the context of Christian religious education. This study provides practical recommendations to enhance the role of teacher and parent creativity in strengthening children's interest in learning through Christian religious education, with the hope of improving the quality of Christian religious education that children receive.

The practice of polygamy is a problem in the family that often occurs, in the Christian faith polygamy is in conflict with the principle of marriage. Family is God's creation since the beginning of the first human being, namely Adam and Eve. God first made humans a pair, so it is clear that in the event that the first humans had one husband and one wife, with this statement we can conclude that polygamy is not permitted by Christians and with polygamy is strictly prohibited in the Christian faith. The point of polygamy is to have more than one wife and that the Bible does not approve of polygamy happening. God does not approve of the marriage of more than one wife in Genesis 2:24 where it is very clear that a man will unite with his wife so that they become one flesh.

One type of cybercrime that is currently trending is online gambling. This paper will discuss the problems of the efforts of the Banyumas Police in tackling online gambling crimes and what are the obstacles for the Banyumas Police in tackling online gambling crimes. The discussion shows that the efforts of the Banyumas Police in tackling criminal acts of online gambling have made three efforts, namely pre-emptive, preventive and repressive efforts. Obstacles to the Banyumas Police in tackling online gambling crimes are due to a lack of public awareness which is still reluctant to report perpetrators or places that carry out gambling to the police, so that this will slightly hinder the police's efforts.

Masalah penguasaan terhadap kepemilikan tanah tanpa hak selama ini menjadikan problematika serius, dikarenakan bukan saja dapat merugikan masyarakat sebagai korban atau pihak yang bersangkutan, namun juga merugikan Negara. Kepemilikan atau penguasaan tanah tanpa hak yang dimaksud diantaranya adalah dengan cara memalsukan terhadap sertipikat sebagai tanda bukti kepemilikan hak atas tanah, atau yang sering disebut dengan istilah ‘mafia tanah’. Metode penelitian yuridis normatif dipergunakan dalam tulisan ilmiah ini. Penelitian hukum kepustakaan dilakukan dengan cara meneliti bahan-bahan pustaka atau data-data sekunder terkait topik penelitian. Pemerintah telah menerbitkan Petunjuk Teknis Nomor. 1/ JUKNIS/ D.VII/ 2018, tentang Pencegahan dan Pemberantasan Mafia Tanah. Sanksi pidana dapat dikenakan bagi mafia peradilan. Masyarakat sebagai pemilik tanah dapat melakukan pencegahan dengan cara mencermati praktek mafia tanah yang mencurigakan dan berpotensi menimbulkan kerugian. Mafia tanah sulit diberantas dikarenakan masalahnya rumit diselesaikan, dikarenakan memanfaatkan kelemahan birokrasi serta menggandeng aparat hukum dan birokrasi terkait. Selanjutnya, masyarakat diharapkan dalam mendaftarkan tanah miliknya dengan cara diurus sendiri adalah merupakan salah satu peran atau pemberdayaan guna menekan atau meminimalisir praktek mafia tanah yang berkeliaran di Negara Indonesia. Oleh karenanya diperlukan pemberian hukum pidana yang tegas, tanpa pandang bulu. Baik bagi pelaku mafia tanah maupun birokrasi yang diajak melakukan kejahatan. Selain itu diperlukan penataan birokrasi dengan mengedukasi tugas dan kedudukan masing-masing berdasar ketentuan dan perundangan, mulai dari Kepala Desa/ Lurah dan/atau perangkat desa, Notaris dan Pejabat Pembuat Akta Tanah (Notaris-PPAT), serta para pejabat Badan Pertanahan hinga Kementerian Agraria dan Tata Ruang/ Badan Pertanahan Nasional (Kementrian ATR/ BPN).

Mining cryptocurrencies on the blockchain is a method for collecting crypto by breaking secret codes compiled with mathematical algorithm equations. Miners will receive rewards in the form of digital coins according to the amount of crypto mined and the type of crypto, this is because each crypto has its own level of difficulty. Crypto includes electronic money (e-money), where the use of e-money as a medium of exchange in modern transactions is still being debated among contemporary scholars about its legitimacy. Two things that become the problem are (1) what is the mechanism for mining cryptocurrency on the blockchain, (2) how is the review of Islamic Economic Law on cryptocurrency mining on the blockchain. The purpose of this study is to describe and explain cryptocurrency mining practices on the blockchain and to find out the review of Islamic Economic Law on cryptocurrency mining. This research is a qualitative research by collecting data and information through interviews. The data sources include primary data sources, namely interviews with crypto miners, secondary data sources, namely books, journals, theses, scientific papers and other written works. While the tertiary data comes from dictionaries, encyclopedias, and related articles. This research data collection method obtained from interviews, observation, and documentation. While the method used to analyze the data is a qualitative analysis method using the theory of mining, al-mal, and ju'alah. From the research results it is known: (1) The cryptocurrency mining mechanism on the blockchain is carried out with a supercomputer facilitated by a GPU, FPGA or ASIC by using certain scripts on the BTC/ETH network to find new blocks containing crypto to get rewards (sell). (2) According to the Sharia Economic Law review of mining cryptocurrency on the blockchain, crypto reward (ju'al) results can be accepted as assets according to the definition of the Hanafiyyah scholars, Ibn Abidin, Imam az-Zaila'i, Imam al-Syatibi, Ibn Arabi and Syafii scholars. However, it is not accepted as a means of payment like conventional money (gharar, dharar, qimar), but both must comply with the conditions and limits set by the Shari'a, this is stated in the Fatwa of the National Sharia Council-Indonesian Ulema Council No: 116/DSN-MUI/ IX/2017 concerning Sharia Electronic Money.

The discourse on usury is a classic issue, both in the development of Islamic thought and in Islamic civilization. Riba is a complicated problem that often occurs in society. The research focus that forms the basis for this research is (1) What are the opinions of the 4 madzhab scholars regarding usury? (2) What are the opinions of contemporary scholars about bank interest?, and the purpose of this research is (1) to find out what the opinions of 4 madhhab scholars about usury are, (2) to find out what contemporary scholars think about bank interest. This research is a type of library research. The results of this study are that the opinion of the Hanafi Madzhab regarding the sale and purchase of goods that are exchanged or weighed with usury goods if they are weighed for trading and there is an addition, it can be said that usury fadhl. The opinion of the Maliki school of illat usury is when usury goods are used as a price. According to the opinion of the Shafi'i Madhhab, illat usury focuses on usury goods when they become the value of the price, if the two goods are valued or become the price of something. While illat on food is anything that can be eaten and fulfills several criteria such as food or staple food, according to the Hambali Madzhab what can be said is usury is every sale and purchase of a kind that is weighed with one date. Bank interest according to the opinion of contemporary scholars, namely KH. Sahal Madfudh explained about the exploitative, inhuman and consumptive nature of bank interest. Therefore, the concept of bank interest for productive behavior for people's business according to kyai sahal is permissible. Meanwhile, bank interest for consumptive and unproductive behavior is prohibited. According to M. Quraish Shihab, bank interest is not illegal, considering that the current interest does not contain elements of persecution and oppression among human beings. According to him, it does not prohibit bank interest because there are still scholars who allow it, because the interest has been agreed upon at the beginning of the transaction and does not contain elements of oppression and persecution, but if you want to be safe, you should make transactions at Islamic banks. Yusuf Al-Qardhawi said that bank interest taken by savers at the bank is usury which is forbidden, Yusuf Qardhawi firmly stated that bank interest is the same as usury which will always be punished as haram.

Children are national assets who have the right to grow and develop optimally. Living on the streets is very dangerous for children. The aim of the research is to determine the application of the principle of regional autonomy in developing social welfare for neglected children and the obstacles in overcoming the problems of abandoned children in Serang City. The research uses qualitative methods with a case study approach. This research concludes that the Regional Government of Serang City, in implementing the principle of regional autonomy for the welfare of neglected children based on Law Number 23 of 2014, has the authority to make regional policies that have an impact on prosperity and general welfare in its region. The Serang City Government is responsible for providing social services to neglected children by providing children's rights and protecting them from the risks and threats of life on the streets. The obstacle to handling the problem of abandoned children is the mindset of abandoned children and families which are still oriented towards financial conditions as the main reference, thereby ignoring risks and other threats of danger. Problems with the level of education, habits of abandoned children and limited budgets provided also become obstacles to the implementation of handling abandoned children..

The main problem in this paper is the unsatisfactory student learning outcomes caused by several factors, namely factors from within the students themselves, namely student interest, attention, talent and student IQ and factors from outside the student's self, namely environmental factors. This is evidenced by the lack of students' understanding of historical material about Islam in the modern era (1800-present). In addition, learning activities often only store event names, chronologies, years, and character names. Therefore it is hoped that the use of audio-visual learning media can arouse students' interest and not be boring. The purpose of this research is to find out how the learning outcomes are using audio-visual media in learning Islamic Religious Education Class XI SMKN 2 Bukittinggi.
