Background: Smoking is known to have adverse effects on various human body systems. While previous studies have predominantly emphasized the harmful effects of smoking on other organs, the impact on the musculoskeletal system has been relatively understudied. This study aimed to survey the association between hookah smoking and musculoskeletal conditions. Materials and Methods: This descriptive cross-sectional study was conducted on 4026 participants selected from baseline data of the Bandar-Kong non-communicable diseases (BKNCD) cohort study in southern Iran. Skeletal muscle injuries were identified through the medical questionnaire of the cohort based on the participants’ history, where "yes" denoted the presence of injuries and "no" indicated their absence. Statistical analysis was performed by SPSS software, version 26 at a significance level of P<0.05. Results: Among the 4026 participants, 2315(57.5%) were women and 1711(42.5%) were men. The mean age of participants was 48±9 years. Among 709 hookah users, 20(2.83%) and 40(5.64%) cases suffered from movement disorders and osteoporosis, respectively. Also, 108(15.23%) and 284(40.05%) hookah users experienced back pain and joint pain, respectively. The odds ratio (OR) of movement disorder was 2.38 times higher for hookah smokers than non-smokers (OR=2.38; P=0.002). There was no significant relationship between hookah smoking and other injuries (P>0.05). Conclusion: The most common problem was joint pain. The mechanism of the effect of smoking on injuries was unknown. Further studies, with larger sample sizes, are necessary to evaluate the association between hookah smoking and musculoskeletal injuries.
Forest Fire Hazard Forecasting Based on Google Earth Engine Open Satellite Data
Authors: Denkov Ivan , Nazarenko Yevhen
Published: October 2024

Introduction. Forest fires cause significant damage to both the natural fund and the national economy. In recent years, their harmful influence has increased due to global warming, and in Ukraine also due to the armed conflict. Thus, traditional methods of patrolling (ground and air) are not only costly, but also dangerous due to mines and possible shelling of border areas. Therefore, the role of surveillance using satellite systems is increasing. Space monitoring is more efficient and covers a larger area of ??the Earth's surface. Another important advantage is open access to information.
The purpose of the paper is to build a mathematical model for determining fire danger based on climatic and biophysical satellite data for the forests of Ukraine, as well as a similar climatic zone with the possibility of further scaling to other climatic regions and types of vegetation cover. To adhere to the principles of open science, Google Earth Engine (GEE), a cloud-based platform that provides open access to dynamic collections of pre-processed Earth remote sensing results, was chosen.
Results. Climatic and biophysical data for the forests of Ukraine for the years 2017-2020 were collected using the tools of the Python library for working with GEE data. Further, the obtained data were processed by two methods: linear (PCA) and non-linear (UMAP) in order to obtain statistically independent attributes. Both obtained datasets were subjected to statistical processing using the Bayesian method. Finally, for each point on the map for which information was collected, an indicator was calculated that predicted fire danger if the obtained value was greater than 1 and its absence in the opposite case.
The resulting model showed its efficiency on training data. On the test dataset (data on Polish forests for the same period), the results turned out to be worse, in particular, the model using PCA did not predict absence of fire danger, and the model using UMAP generally showed lower performance. This can be due to both the imperfection of the model and the small size of the test dataset or factors unrelated to natural processes (in particular the human factor).
Conclusions. An approach to forest fires forecasting based on satellite data is proposed. The obtained results indicate that the model is already effective at this stage, although machine learning methods have not yet been applied. However, it needs further improvement, so work on the model will be continued. Along with improving the quality of forecasts, attention will be paid to the geographic expansion and the creation of a web application. Keywords: fire danger in forests, satellite data, correlation, PCA, UMAP, hard-to-reach areas.
A Combined Quasi-Newton-Type Method Using 4th-Order Directional Derivatives for Solving Degenerate Problems of Unconstrained Optimization
Authors: Zadachyn Viktor
Published: October 2024

Introduction. Methods of unconstrained optimization play a significant role in machine learning [1–6]. When solving practical problems in machine learning, such as tuning nonlinear regression models, the extremum point of the chosen optimality criterion is often degenerate, which significantly complicates its search. Therefore, degenerate problems are the most challenging in optimization. Known numerical methods for solving the general unconstrained optimization problem, up to the second order, have very low convergence rates when solving degenerate problems [7, 8]. This is explained by the fact that for a significant improvement in convergence rate in this case, it is necessary to use higher-order derivatives in the method than the second order [10].
The purpose of the paper is to develop an efficient quasi-Newton method for solving degenerate unconstrained optimization problems, the idea of which (unlike regularization) involves dividing the entire space into the sum of two orthogonal subspaces. This idea was introduced in [23]. The space division at each iteration of the method is based on the spectral decomposition of the matrix approximating the Hessian of the objective function using the BFGS formula [3]. Each subspace exhibits its own behavior of the objective function, and therefore, an appropriate minimization method is applied on it.
Results. A combined quasi-Newton method is presented for solving degenerate unconstrained optimization problems, based on orthogonal decomposition of the Hessian approximation matrix and division of the entire space into the sum of two orthogonal subspaces. On one subspace (the kernel of the Hessian approximation matrix), a method is applied where derivatives in the direction of the 4th order are computed, while on the orthogonal complement to it, a quasi-Newtonian method is applied. A separate one-dimensional search is applied on each of these subspaces to determine the step multiplier in the respective direction.
The effectiveness of the presented combined method is confirmed by numerical experiments conducted on widely accepted test functions for unconstrained optimization problems. The proposed method allows obtaining fairly accurate solutions to test tasks in case of degeneracy of the minimum point with significantly lower computational costs for gradient calculations compared to optimization procedures of well-known mathematical packages.
Conclusions. The idea of dividing the entire space into the sum of two (or possibly more) orthogonal subspaces when solving complex optimization problems is quite promising in terms of applying a combination of different numerical methods on separate subspaces.
In the future, it is planned to conduct theoretical research on the convergence rate of the presented combined method in solving degenerate unconstrained optimization problems. Keywords: unconstrained optimization, quasi-Newton methods, degenerate minimum point, spectral matrix decomposition, Machine Learning.

Published: October 2024

Introduction. The quadratic assignment problem is a well-established NP-hard problem in combinatorial optimization with applications in diverse fields like economics, archaeology, and chemistry. Due to its complexity, research on efficient solution methods remains active, including efforts for parallelization on multiprocessor computing systems. However, effective parallel algorithms are crucial to fully leverage these computational resources. In this context, algorithm unions (portfolios and teams) play a significant role in achieving parallel execution for solving such problems.
Research objectives. This work investigates the application of portfolios constructed from modifications of the repeated iterated tabu search algorithm to the quadratic assignment problem. The effectiveness of these portfolios was evaluated through experimental computations.
Results. The portfolios, derived from modifications of the repeated iterated tabu search algorithm, were applied to the quadratic assignment problem. For the most demanding test instances, the proposed algorithms were evaluated on the SCIT-4 supercomputer, alongside previously published results from the authors, confirming their competitive performance. Additionally, we assessed the parallel efficiency of these portfolios in solving instances of the quadratic assignment problem. The results demonstrate their ability to accelerate the optimization process (with speedup dependent on problem size and utilized processors), enabling the solution of large-scale problems.
Conclusions. The conducted studies demonstrate that employing algorithm portfolios significantly accelerates the solution process for the quadratic assignment problem. Analysis of the results reveals a near-linear speedup factor achieved by the portfolio. For the challenging test instance tai100a, a new best solution value of 21040996 was obtained using a portfolio of 16 algorithms. Keywords: quadratic assignment problem, algorithm portfolios, experimental research, algorithm portfolios efficiency.

Unmanned aerial vehicles (UAVs) are attracting considerable interest in a variety of areas, such as logistics, defence, search and rescue, agriculture, manufacturing and environmental monitoring. The effective use of these flexible resources requires the development of models and methods that ensure the creation of safe and efficient flight routes for UAVs.
The purpose of the paper is to study the current state of UAV routing problems, including an analysis of existing research in this field and systematization of scientific approaches and algorithms as well as the formalization of some practically important problems.
Results. A classification of UAV routing problems has been proposed based on various criteria, including the number of UAVs, the number of base locations, UAV recharging constraints, additional conditions, evaluation criteria, and the constancy of conditions. An analysis and classification of UAV routing problems are presented, highlighting the significance of these problems in various fields such as logistics, defense, agriculture, and others. Meaningful formulations of several interrelated practical UAV routing problems have been proposed, and their formalization has been carried out in the form of specific mathematical models.
Conclusions. The development of unmanned aerial vehicles (UAVs) is a dynamic and relevant area with a wide range of applications. The paper systemises scientific approaches and algorithms for optimising UAV routes, analyses and classifies routing problems according to various criteria. The proposed classification allows for a better understanding of the structure of the problems and the selection of appropriate methods for solving them. The main result is the formalisation of a number of practical UAV routing problems in the form of mathematical models, which allows developing effective algorithms for solving these problems, increasing the efficiency of UAVs in various fields, such as logistics, defence and agriculture. Keywords: route optimization, unmanned aerial vehicle, drone, mathematical model, flight resource, combinatorial optimization, monitoring, logistics.
One hundred years of inlet processes and barrier adjustments at North Inlet, SC
Authors: Barrineau Patrick
Published: October 2024

Debidue Beach and North Inlet are a coupled mixed-energy inlet-barrier system along the South Atlantic Bight in South Carolina, USA. Long-term chronic erosion along much of Debidue throughout the 20th century is the result of a shoreline adjustment triggered by an avulsion in the main channel of North Inlet occurring between 1926 and 1934. We use a historical database of shoreline positions compiled by the United States Geological Survey (USGS) and the Analysis of Moving Boundaries Using R (AMBUR) package to quantify changes in the Debidue Beach shoreline over nearly 150 years from 1872 to 2011. This analysis documents relatively large-scale shoreline changes (and equivalent volumetric changes above local depth of closure “DOC”) following the shift in channel position, and a logarithmic decrease in erosion rates over the following decades. Mixed-energy ebb-dominant inlets have considerable effects on adjacent beaches due to their ability to retain and shed large quantities of sand relatively quickly. This study demonstrates that even systems exhibiting long-term stability — like North Inlet — are indeed migrational landforms and should be considered as such when formulating shoreline management plans along adjacent beaches.
Planning protected area networks for surfing resources
Authors: Reineman Dan R. , Blum Michael L. , Reiblich Jesse , Sancho-Gallegos Diego A.
Published: October 2024

Surf breaks are vital cultural resources on coastlines worldwide, but are vulnerable to myriad threats, including climate change and coastal development; as such, efforts to protect them have proliferated. Hitherto, spatial protections (e.g., marine protected areas; MPAs) have been pursued for surf breaks as single, individual reserves. This situation is comparable to the early days of biodiversity MPAs, which eventually progressed to networked reserve design, initially culminating in California’s 124 net- worked MPAs. Here, we apply the analogy of networked biodiversity reserve design to networked reserves for surf break protection. We examine the proposition that the effectiveness of surfing resource conservation can be improved by a “networked” approach. We conclude that specific characteristics of surf breaks, including their size, type, carrying capacity, quality, value, accessibility, spacing, vulnerability, and cultural and historic significance could all be considered and balanced to yield more effective, equitable conservation outcomes.
Influence of structure characteristics on wave transmission and shoreline response at a low-crested segmented breakwater in Little Egg Harbor Township, NJ
Authors: Gannon Katherine M. , Janssen Matthew S. , Miller Jon K.
Published: October 2024

Graveling Point Beach, a public beach within Little Egg Harbor Township, New Jer- sey, has been experiencing long-term erosion. To address the issue, a living shoreline project consisting of four low-crested rubble-mound breakwaters and a beach nour- ishment was constructed beginning in fall 2022 (structures) and finishing in spring 2023 (beach nourishment). A variety of field methods were used to investigate the influence of the breakwater system on wave transmission and beach fill evolution. The observations are then compared to common empirical estimations. A median wave transmission coefficient of 0.4 was measured for incident waves with a median height and peak period of 9 cm and 2 sec, respectively. The observed transmission coefficient was higher than that predicted by models such as Briganti et al. (2003) and Van der Meer and Daemen (1994) suggesting other processes such as diffraction may be influencing the results. Structure from Motion (SfM) was used to generate a series of Digital Elevation Models (DEMs) which show salients forming behind the structures. The resulting salient growth was compared to the model of Suh and Dalrymple (1987), which was shown to overpredict the amplitude of the salient at Graveling Point. However, the expected relationship of breakwaters with increased offshore distance having shorter salient lengths was generally observed. The equation was refit using the field data at Graveling Point and laboratory data with similar wave heights and periods from Suh and Dalrymple to derive a modified model that may be more appropriate in low-energy environments

Alat dan Mesin Pertanian (Alsintan) merupakan alat pertanian yang digunakan sebagai fasilitas bantuan untuk memudahkan serta membantu para petani dalam proses pengelolaan lahan sampai hasil pertanian. Proses untuk mendapatkan manfaat Alsintan melibatkan kelompok petani yang mengajukan permintaan bantuan kepada dinas pertanian. Selanjutnya, petugas meninjau dokumentasi untuk menentukan kesesuaiannya, setelah disetujui proposal dikirim ke otoritas pusat (Kementerian Pertanian). Identifikasi kelompok petani yang memenuhi syarat untuk bantuan saat ini dilakukan masih bersifat manual, tidak memiliki sistem untuk mencatat data penilaian, yang mengakibatkan alokasi bantuan yang kurang tepat dan terarah. Penelitian ini bertujuan untuk menentukan penerima bantuan yang layak dan pantas mendapatkan dukungan Alsintan dengan menerapkan konsep pendukung keputusan. Sistem pendukung keputusan adalah proses metodis dalam memilih opsi terbaik dari beberapa pilihan lalu menggunakan opsi pilihan tersebut untuk memecahkan permasalahan secara metodis. Metode yang dipakai untuk penelitian penentuan penerima Alsintan yaitu kombinasi Multi Attribute Utility Theory (MAUT) dan Analytic Hierarchy Process (AHP), dimana metode AHP digunakan sebagai penentuan bobot kriteria dan metode MAUT digunakan untuk perangkingan alternatif. Metode AHP memiliki 7 tahapan yaitu membuat struktur hirarki, kriteria perbandingan berpasangan, menghitung konsistensi logis, menghitung eigen vector, menghitung Consistency Index (CI), menghitung Consistency Ratio (CR), dan memeriksa konsistensi. Metode MAUT terdapat 4 tahapan diantaranya membuat matriks keputusan, menghitung normalisasi matriks, menghitung utilitas margin, dan menghitung utilitas akhir. Dataset yang didapatkan dalam penelitian berjumlah 54 data dimana data yang digunakan untuk perhitungan dengan menerapkan metode AHP dan MAUT yaitu 10 data. Hasil akhir perhitungan menggunakan metode AHP dan MAUT menghasilkan alternatif yang mendapatkan nilai total tertinggi yaitu alternatif Sidabu-dabu dengan nilai total 0.9271, sedangkan alternatif dengan nilai total terendah yaitu alternatif Sejahtera dengan nilai 0.1864.

Data Mining adalah teknik krusial untuk mengolah dataset besar dan kompleks guna menemukan pola tersembunyi yang mendukung keputusan strategis. Penelitian ini menerapkan teknik Data Mining dengan fokus pada metode Rough Set dan Support Vector Machine (SVM) untuk meningkatkan penilaian kinerja pegawai dan memberikan rekomendasi promosi jabatan yang lebih efektif dan objektif. Metode Rough Set digunakan untuk melakukan seleksi atribut dari data evaluasi kinerja pegawai, mencakup tujuh atribut utama seperti pengalaman kerja, pendidikan, usia, jenis jabatan, golongan ruang, hasil kerja, dan perilaku kerja. Data yang digunakan berasal dari laporan evaluasi kinerja 8.457 pegawai di Badan Kepegawaian dan Pengembangan Sumber Daya Manusia (BKPSDM) Kota Padang. Setelah atribut-atribut penting terpilih, data tersebut digunakan sebagai input dalam model SVM yang diimplementasikan menggunakan software Weka. Model ini berhasil mencapai tingkat akurasi sebesar 99,6216%, yang diperoleh dengan membagi jumlah data yang diklasifikasikan dengan benar oleh sistem dengan jumlah total data pegawai yang digunakan. Berdasarkan hasil confusion matrix, kelas "sangat baik" menunjukkan precision 1,000, recall 0,952, dan F-Measure 0,975; kelas "baik" dengan precision 0,996, recall 1,000, dan F-Measure 0,998; serta kelas "sangat kurang" menunjukkan precision 0,990, recall 0,987, dan F-Measure 0,988. Sebanyak 317 instance terklasifikasi benar sebagai "sangat baik," 7.722 instance sebagai "baik," dan 386 instance sebagai "sangat kurang," namun tidak ada instance yang terklasifikasi benar sebagai "perlu perbaikan." Penelitian ini juga melakukan perhitungan manual menggunakan sampel 26 data, di mana perhitungan menggunakan 3 data untuk testing. Hasil perhitungan manual menunjukkan bahwa data 1 dan data 2 termasuk dalam kategori "butuh perbaikan," sementara data 3 termasuk dalam kategori "sangat kurang." Berdasarkan aturan pemetaan, di mana hasil klasifikasi dengan nilai sign negatif mendekati -114 dikategorikan sebagai "sangat kurang," ketiga data testing tersebut konsisten dalam kategori "sangat kurang." Perbandingan hasil perhitungan manual dengan aplikasi menunjukkan akurasi 33,33%, di mana 1 dari 3 data testing sesuai antara manual dan aplikasi. Meskipun ada tantangan dalam mengidentifikasi beberapa kelas, sistem penilaian ini dapat membantu manajemen dalam membuat keputusan promosi yang lebih baik. Penelitian ini menggambarkan potensi besar teknik Data Mining dalam memperbaiki proses penilaian kinerja dan rekomendasi jabatan dalam organisasi.

Published: October 2024

Program inseminasi merupakan usaha yang dilakukan pasangan suami-istri yang tidak bisa memiliki keturunan secara alamiah untuk memiliki anak tanpa melakukan adopsi. Hukum Islam memandang program ini sebagai perbuatan yang terhormat karena dapat membantu pasangan suami-istri. Ulama membolehkan program inseminasi buatan pada bayi tabung jika benih diperoleh dari sperma dan ovum suami-istri yang sah. Adapun tujuan dari kajian ini adalah untuk menjelaskan istibath yang digunakan Yusuf al-Qardhawi di dalam menghukumi kasus inseminasi buatan dan untuk mendeskripsikan hukum anak hasil inseminasi buatan pada donor konsafsi perspektif Yusuf al-Qardhawi. Penelitian ini menggunakan metode penelitian kepustakaan (library research). Berdasarkan pemaparan dapat disimpulkan bahwa hukum inseminasi buatan pada manusia dalam perspektif Yusuf al-Qardhawi yaitu tidak boleh dilakukan hanya dalam keadaan darurat, sehingga jika kondisinya tidak darurat tidak diperbolehkan melakukan inseminasi buatan. Darurat dalam pandangan Yusuf al-Qardlawi hanya dalam satu bentuk saja, yaitu kebutuhan yang sangat mendasak saja. Kebutuahan yang sangat mendesak yakni mendapat keturunan dalam pasangan suami-istri, karena mendapat keturunan bagi pasangan suami-istri termasuk bagian dari ahkam al-khamsah yakni hifdh an-nasl, kemaslahatan yang diperoleh adalah dalam menjaga dan melestarikan keturunan. Selanjunya, tidak diperbolehkan melakukan inseminasi buatan apabila asal benih yang digunakan dari pasangan suami dan istri, kemudian di tranplantasikan pada rahim istri.

Marriage always raises various problems. So is engagement, which is the first step toward marriage. Even though no contract can unite the two parties in a legal bond according to religious law, the cancellation of an engagement remains a serious problem that should be considered by Islamic family law practitioners and local religious leaders because the cancellation of an engagement can have legal consequences for both of them, related to the rights and status of the property given during the engagement process. Therefore, it is necessary to have an Islamic legal view to clarify the position of gifted assets in an aborted engagement by producing a conclusion that the gifted property is called a gift.
From the description of the problem above, the author focused on three things; (1) how the practice of giving property in the engagement process was, (2) how the custom of withdrawing property gifted in a canceled engagement was, and (3) what the view of Islamic law regarding the custom of withdrawing gifted property in an annulled engagement (Case study in the village of Kandang Central Tebo District, Tebo Regency, Jambi Province) was.
This type of this research was qualitative, through observation techniques, interviews, data collection, and documentation. The collected data were analyzed using triangulation research.
The study results concluded that in its practice, the custom of withdrawing property from a canceled engagement in the village of Kandang must have invited the Traditional Leader, Village Officials, and also Nenek Mamak. According to the view of Islamic law, the gift of wealth in a engagement is a gift, it is a contract to give one person's property to another without any reward as a tribute or achievement, not a dowry, a grant, or charity. Because in Islamic law, gifts in engagement can be achieved through the istishlahiy/maqashidiy method, it is an ijtihad method that refers to maqasid al-shari'ah.

Humans are creatures that cannot live individually. Definitely need help from other people in living a life. One proof of the truth of this statement is the presence of marriage. Marriage is a path taken by men and women who love each other and have a strong desire to create a family. A sakinah, mawaddah and rahmah family is of course the goal of all married couples, and this cannot be achieved without cooperation between husband and wife in the form of fulfilling the rights and obligations between the two which are based on equality, balance and justice. Based on the explanation above, it is important to have effective communication, in undergoing a husband and wife relationship, especially for husband and wife who are far apart, which is popularly known as Long Distance Relationship (LDR) or Long Distance Marital in Relationship. Frequently communicating effectively can be a joy for a husband and wife because they have not met for a long time, but on the other hand, the lack of effective communication between the two can cause problems in the family which will end in divorce

There are many things that should be asked by husband and wife when deciding to divorce. In addition the property of gono-gini, another thing that must be considered is the division of child custody in a divorce. by both parents may not injure the fulfillment of children's rights which are also regulated by the state through the child custody law through Law Number 23 of 2002 concerning Child Protection. In General Provisions Article 1 point 11 it is explained that foster care is the power of parents to nurture, educate, nurture, nurture, protect, and develop children according to their religion and abilities, talents and interests. According to Article 41 of Law Number 1 of 1974 concerning Marriage, a married husband and wife are still obliged to maintain and educate their children for the benefit of the child himself. Divorce also does not cancel the father's obligation to be responsible for all the care and education that the child needs. However, the court may decide that the mother also demands it under certain conditions. The court also has the right to determine which custody of the child should be given to the mother or father, especially if there is a right to household rights.

The Direct Cash Assistance (BLT) to Poor Households aims to assist the economy of impoverished communities due to the increase in fuel prices in October 2005. For the village of Sonok, the Direct Cash Assistance Program is provided to categorized poor communities, who are registered through the data collection by the Central Statistics Agency (BPS) in collaboration with the local government. Based on the above, the core issue is the Islamic Legal Perspective on the Mechanism of Distributing Direct Cash Assistance (BLT) Funds in the Village of Sonok.
The research method used in this thesis is a qualitative method with a case study approach. To investigate the research problem, the researcher also employs a descriptive method towards primary and secondary data. The primary data for this thesis is obtained through interviews and documentation. Secondary data consists of information from other sources such as scholarly works, literature, encyclopedias, dictionaries, archives, and research findings related to the problem to be discussed or studied.
From the research conducted, it was found that the BLT assistance has been distributed to both registered and unregistered individuals. As a result, those who receive the BLT assistance do not receive the full amount of 300,000 because of the addition of impoverished residents as per the policy of the local village government. The Islamic legal perspective on the distribution of the BLT funds prohibits this practice, as the existing assistance is intended only for those who are registered. Therefore, the assistance should only be given to them, as it is their rightful entitlement as registered recipients. Anything that is rightfully theirs should be conveyed to them, as it is a trust.

Brokers, now known as intermediaries in the world of commerce, play a significantly more crucial role in the present compared to earlier periods. The strong interconnection between collective traders and individuals in trade renders the broker's role highly important. A broker is someone who sells goods belonging to others in return for compensation commensurate with their efforts. In fiqh literature, activities of this nature are referred to as Samsârah. This research employs a qualitative research method utilizing data collection techniques such as observation and interviews. The primary sources in this study are traders or owners of motorcycles and individuals working as brokers. The research findings indicate that before commencing work as a broker, one must first transact with the motorcycle owner to establish the terms of the job contract. This involves determining the duration of work and the amount of commission earned. Based on the actual facts, the samsarah transactions occurring in Bondowoso align with the principles established by DSN MUI.
PERAN FILSAFAT HUKUM DALAM PEMBENTUKAN HUKUM

Hukum adalah seperangkat aturan yang mengikat secara hukum harus ditaati oleh masyarakat yang mengitarinya. Hukum dibentuk melalui proses pencarian hukum. Hukum dibentuk dilatar belakngi oleh filosofi sebagai sandaran  nilai dalam mencari dan membentuk hukum. Hukum bukan hanya dibentuk seadanya. Hukum dibentuk dengan dasar filsafat hukum sebagai roh terbentuknya hukum. Oleh karena itu idealnya hukum harus dibentuk dengan dasar filsafat hukum. Dengan hakikat hukum dan moral hukum yang baik. Tanpa hal itu maka terbentuknya hukum akan tidak mempunyai nilai hukum. Hukum akan hampa manakala hukum terbentuk  hanya sekeadr formalistik hukum, Akar filsafat itulah yang harus mendasari terbentuknya hukum. Pencarian hakikat hukum akan terpenuhi manakala hukum dibentuk dengan dasar filsafat hukum. Hukum tidak akan terbentuk manakala filsafat atau filosofi hukum tidak mencari nilai-nilai kebenaran hukum. Hukum tidak akan lepas dari ontologi, epistimologi, aksiologi.  Hukum yang baik, hukum yang bermakna lahir dari filsafat hukum yang mendasari terbentuknya hukum.

So far, these rights and obligations have been understood statically, the husband is obliged to earn a living while the wife's obligation is to serve her husband, look after the house and all other domestic duties. Is that true? Couldn't it be if the rights and obligations of husband and wife were understood dynamically?

By using a qualitative research approach, this type of literature study, this research concludes that rights and obligations in the household are a dynamic matter, where husband and wife can work together to earn a living, manage finances together and help each other carry out domestic work. Adapted to situations and conditions and based on the concept of mu'asyarah bi al-ma'ruf.
KONSEP ADIL DALAM PENAFSIRAN AYAT POLIGAMI PERSPEKTIF HUKUM ISLAM
Authors: Yunus Muhammad , Rahwan Rahwan
Published: October 2024

Agama islam datang dengan ajaran yang mengatur poligami, di mana pada kenyataannya belum bisa diterima oleh semua kalangan. Di satu pihak menganggap ketentuan poligami sebagai aspek diskrminatif islam terhadap kaum wanita, dan di pihak lain menganggap bahwa ketentuan poligami dapat menjadi alternatif dari masalah perselingkuhan dan prostitusi. Salah satu penyebab perbedaan pandangan tersebut adalah pemahaman mengenai dalil poligami itu sendiri, di mana ayat al Qur’an yang menjadi dalil kebolehan poligami, juga menjadi dalil kelompok lain untuk melarang poligami. Maka terdapat 2 pertanyaan yang menjadi fokus penelitian ini, yakni tentang bagaimana pemahaman konsep adil pada ketentuan poligami dalam al Qur’an, dan bagaimana pula pemahaman konsep adil dalam poligami menurut sudut pandang hukum islam. Untuk menjawab permasalah itu, peneliti  menggunakan pendekatan penelitian kualitatif dengan metode penelitian kepustakaan (library research) untuk mendalami fenomena tersebut. Sumber data literatur mengenai pandangan berbagai pakar dan penafsiran tentang ayat al Qur’an yang berbicara tentang poligami, ditelaah dengan menggunakan sudut pandang hukum islam, mulai dari konsep poligami hingga konsep adil yang ada di dalamnya. Dari pembahasan itu kemudian diperoleh kesimpulan bahwa melakukan poligami bukan merupakan perkara mudah, namun bukan juga hal yang mustahil, karena merujuk kepada bagaimana proses penerapannya dari tokoh teladan terdahulu dan juga sikap adil yang menjadi persyaratannya. Selain itu,dapat dipahami juga bahwa makna adil dalam al Qur’an surat al-Nisa’ ayat 3 mencakup adil material dan immaterial, namun menurut mayoritas ulama yang dimaksud dalam ayat tersebut adalah adil yang bersifat material.
