Abstract

This research aims to examine the concept of imk?n al-ru’yah according to Sayyid Usman in the book Iqaz an-Niyam fi Ma Yata'allaq bi Ahillah wa as-Siyam and to analyze its relevance to contemporary crescent visibility criteria. The implementation of this research uses a approach qualitative based on a number of literature review, relying on Iqaz an-Niyam fi Ma Yata'allaq bi Ahillah wa as-Siyam as the primary source, along with e-journals, reference books, and relevant literature as secondary sources. The results show that Sayyid Usman's concept of imk?n al-ru’yah is drawn from the views of various scholars, stipulating that in some locations, the new crescent can only be sighted if it reaches a minimum altitude of 7 degrees, while in other places, an altitude of 8 degrees or more is required for visibility. Sayyid Usman's concept of imk?n al-ru’yah remains relevant to contemporary crescent visibility criteria. The relevance between Sayyid Usman's concept of imk?n al-ru’yah and contemporary visibility criteria lies in their common round in establishing crescent visibility standards, despite significant differences in their approaches.

Abstract

The purpose of this study is to explore the implementation mechanism of Perampam Dene within the Gayo community and to what extent the Gayo Customary Council plays a role in preserving customary values, strengthening social bonds, and resolving potential post-marital conflicts. This research uses a qualitative method with a descriptive approach, employing data collection techniques such as in-depth interviews, observation, and documentation. The informants consist of traditional leaders, members of the Gayo Customary Council, and family members involved in the practice of Perampam Dene. The findings reveal that the Gayo Customary Council acts as a mediator, facilitator, and moral guardian in the prenuptial agreement process. In addition to ensuring that the agreement proceeds fairly and aligns with customary norms, the Gayo Customary Council also plays a strategic role in maintaining social harmony. This role reflects the principles of maslahah mursalah in Islamic law, which refers to collective benefit that does not contradict Sharia. Therefore, the Gayo Customary Council serves as a key actor in harmonizing customary law with Islamic values in the marriage practices of the Gayo community.

Abstract

Islamic teachings in Indonesia have been influenced by ulama, or Islamic thinkers from Saudi Arabia (Haramin). One of these Islamic teaching areas is rukyyahhisab. One of prominent Islamic teachings on rukyah was spread by Mas Manshur al-Batawi. While, his teaching, which was based on Ptolomeus' Geocentrics theory, was being put aside as the Geocentric theory itself and was replaced by Heliosentrics theory, interestingly, his teaching is still widely used in deciding the starting Qomariyah month by many muslim communities in Indonesia, including al-Khairiyah al-Manshuriyah Jakarta and Pondok Pesantren Ploso Mojo Kediri, East Java. Meanwhile, Mas Manshur al- Batawi admitted the existence of this loophole as well. Thus, I am interested in researching further on his Islamic thinking in this study.

Abstract

A radial distribution electrical network at a certain distance will have a large voltage loss due to conductive losses, especially at the endpoint. The tip voltage is determined by the distance of the distribution and the amount of load. The form of configuration also affects the amount of power loss and voltage loss. So that a good configuration is needed in order to obtain good efficiency. Reconfiguration of the distribution network is used to reset the network configuration form by opening and closing switches on the distribution network. Reconfiguration is expected to reduce power losses and improve distribution system reliability. Many feeders and buses on the network if calculated manually will be difficult and require a very long time. So it is necessary to solve problems using program assistance. In this case, use Particle Swarm Optimization (PSO). Particle Swarm Optimization (PSO) algorithm based on the behavior of a herd of insects, such as ants, termites, bees, or birds. BPSO is a development of the PSO algorithm designed to solve the optimization problem in a discrete combination, where the particle takes the value of binary vectors with length n and speed which is defined as the probability of bits to reach value 1. The results show a significant reduction in losses.

Abstract

Partai Nasional Indonesia (PNI) adalah salah satu partai politik yang memainkan peran penting dalam sejarah perjuangan Indonesia untuk kemerdekaan. PNI didirikan oleh Soekarno di Bandung pada 4 Juli 1927, dengan dasar nasionalisme dan anti-kooperatif terhadap pemerintah kolonial Belanda. Partai ini memainkan peran penting dalam meningkatkan kesadaran nasional dan mendukung kemandirian politik negara. PNI sempat dibubarkan pada 1931, tetapi terus berubah, menjadi bagian dari fusi Partai Demokrasi Indonesia (PDI) dan kemudian menjadi Partai Demokrasi Indonesia Perjuangan (PDIP). Dalam artikel ini, kami akan membahas sejarah PNI, fungsinya, dan pengaruh terhadap perkembangan politik Indonesia sebelum dan sesudah kemerdekaan. Penelitian ini memberikan wawasan tentang kontribusi partai ini dalam membangun identitas nasional dan sistem politik Indonesia dengan melihat perjalanan PNI.

Abstract

The Blood Transfusion Unit (UTD) of the Indonesian Red Cross (PMI) in Probolinggo Regency faces challenges in managing blood supplies, particularly for Packed Red Cells (PRC), due to unpredictable fluctuations in demand. The imbalance between supply and demand often leads to shortages or surpluses, affecting the quality of healthcare services. This study aims to predict the demand for PRC to support more efficient inventory management. The method employed is Support Vector Regression (SVR), an approach within the Support Vector Machine (SVM) algorithm that is effective for regression and prediction tasks. Historical blood demand data was used to train the model. The results indicate that SVR provides sufficiently accurate predictions for all blood types, with the best performance achieved for blood type B, yielding a Root Mean Square Error (RMSE) of 0.0589 and a Mean Absolute Percentage Error (MAPE) of 7.11%. In conclusion, the SVR method can be effectively applied to forecast PRC demand and has the potential to support decision-making in blood stock management at the UTD PMI of Probolinggo Regency.

Abstract

Artikel ini membahas pemikiran maqāṣid al-syarī‘ah pada periode modern melalui perspektif dua tokoh penting, yaitu Alal al-Fasi dan Ahmad al-Raisuni. Kajian maqāṣid al-syarī‘ah memiliki peran strategis dalam pengembangan hukum Islam agar tetap relevan dalam merespons dinamika sosial dan tantangan modernitas. Penelitian ini bertujuan untuk mendeskripsikan konsep maqāṣid al-syarī‘ah menurut Alal al-Fasi, menganalisis teori maqāṣid al-syarī‘ah dan maqāṣid al-Qur’an menurut Ahmad al-Raisuni, serta membandingkan pemikiran keduanya dalam konteks hukum Islam kontemporer. Penelitian ini menggunakan pendekatan kualitatif dengan metode studi kepustakaan (library research). Data diperoleh dari karya-karya primer kedua tokoh serta literatur sekunder yang relevan, kemudian dianalisis menggunakan metode deskriptif dan komparatif. Hasil penelitian menunjukkan bahwa Alal al-Fasi menekankan maqāṣid al-syarī‘ah sebagai ruh syariat yang harus diwujudkan dalam kehidupan sosial melalui ijtihad, pendidikan, dan pembaruan pemikiran Islam. Sementara itu, Ahmad al-Raisuni mengembangkan maqāṣid secara lebih sistematis dan metodologis dengan membagi maqāṣid ke dalam maqāṣid umum, khusus, dan parsial, serta mengaitkannya dengan maqāṣid al-Qur’an. Perbandingan kedua pemikiran ini menunjukkan adanya kesinambungan antara dimensi praksis dan metodologis maqāṣid al-syarī‘ah, yang berkontribusi dalam memperluas cakrawala hukum Islam agar lebih kontekstual dan berorientasi pada kemaslahatan umat.
