Abstract

This research aims to analyze the Islamic legal thoughts of Nahdlatul Ulama (NU) and Muhammadiyah concerning Islamic economics in Indonesia. The research is based on fatwa documents from Lembaga Bahtsul Masail NU  and  Majelis Tarjih Muhammadiyah from 2000 to 2019. This study found that the method of ijtihād used by NU has shifted from a textual-conservative (qawlī) approach to a contextual-progressive and methodological (manhajī) approach. Meanwhile, the method of ijtihād used by Muhammadiyah is characterized as progressive-dynamic, employing three approaches: bayani, taḥlīlī, and istiṣlāḥī. The decisions of LBM NU in Islamic economics predominantly use the qawlī method, followed by the ilḥaqī method, and subsequently, the manhajī method. The qawlī method is most frequently used because it adheres to the procedural stages of NU's traditionalist pattern, where every legal issue is ideally referenced to authoritative madhhab books. If the issue cannot be resolved using the qawlī method, the ilḥāqī and manhajī methods are employed. This indicates that the manhajī method is used when the qawlī and ilḥaqī methods cannot provide a legal answer. On the other hand, Muhammadiyah's MT method in Islamic economics has evolved. Initially, the tarjīḥ methodology was monodisciplinary, referring issues back to the Quran and the Sunnah. Subsequently, the tarjīḥ methodology became monodisciplinary-pretextual by employing various methods. Eventually, the tarjīḥ methodology became multidisciplinary regarding methods, approaches, and techniques. Abstrak: Penelitian ini bertujuan untuk menganalisis pemikiran hukum Islam Nahdlatul Ulama dan Muhammadiyah tentang ekonomi Islam Indonesia. Penelitian ini bersumber dari dokumen fatwa-fatwa Lembaga Bahtsul Masail (LBM) NU dan Mejelis Tarjih (MT) Muhammadiyah selama periode 2000-2019. Studi ini menemukan bahwa metode ijtihad NU mengalami pergeseran yang awalnya bersifat tekstual-konservatif (qawlī) berubah menjadi kontekstual-progresif dan metodologis (manhajī). Sementara itu, metode ijtihad MT Muhammadiyah bersifat progresif-dinamis dengan tiga pendekatan; bayānī, taḥlilī, dan istiṣlāḥī. Keputusan LBM NU dalam ekonomi Islam lebih banyak menggunakan metode qawlī, disusul oleh metode ilḥāqī, dan selanjutnya metode manhajī. Metode qawlī paling sering digunakan karena mengacu pada tahapan prosedur pola bermazhab NU, dimana setiap persoalan hukum sedapat mungkin merujuk pada kitab-kitab otoritatif mazhab. Jika tidak dapat diselesaikan dengan metode qawlī, maka digunakan metode ilḥāq dan metode manhajī. Ini artinya, metode manhajī digunakan dalam kondisi metode qawlī dan ilḥāq sudah tidak mampu memberikan jawaban hukum. Di sisi lain, metode MT Muhammadiyah dalam ekonomi Islam mengalami evolusi. Pada awalnya, manhaj tarjih bersifat monodisiplin dengan mengembalikan persoalan-persoalan umat kepada al-Quran dan al-Sunnah. Manhaj al-tarjīḥ bersifat monodisiplin-pratekstual dengan menggunakan sejumlah metode. Kemudian, manhaj al-tarjīḥ menjadi multidisiplin baik dari aspek metode, pendekatan, dan teknik.

Abstract

The Sundanese people have long recognized bajidoran as an entertainment art form that presents the aesthetics of dance and traditional Sundanese music (karawitan). However, beneath this surface lies the complexity of power struggles and masculine domination among individuals involved in the Bajidoran Enthusiast Community (Komunitas Pecinta Bajidoran or KPB). Interestingly, the power struggles are not limited to men but also involve women. This phenomenon prompts an inquiry into why bajidoran is heavily associated with practices of masculinity. This study aims to address the following questions: why is bajidoran associated with practices of masculinity, how is this construction process carried out, what are the contributing factors, and what are the implications for the KPB?This research employs a qualitative method with an ethnographic approach, wherein the researcher values the experiences and realities of the subjects under study, even if they differ radically from their own. The researcher applies three characteristics of this new ethnography: honesty, towards other facts, self-reflection, and polyvocality. Data collection involves literature review, observation, interviews, and documentation.The findings of the research explain that: 1) masculinity is strongly embedded in bajidoran due to: firstly, cultural, daily practices, and historical contexts that construct masculinity, which are dialectically intertwined with the experiences of the KPB, both present and past. Secondly, the situational and practical conditions within the bajidoran arena (social relations and interactions) have great potential to generate masculinity. 2) The process of constructing masculinity involves seven stages: production, socialization, appreciation, internalization and externalization, relationships and interactions, staging, and formation. Eight factors contribute to the construction of masculinity: patterns/sequences, the role of the mc and pesinden (vocalists), pencug ibing (leader), kendang (drum), selendang (scarf), economic capital, alcoholic beverages, and musical elements. The results of this research provide insights for the Bajidoran Enthusiast Community and relevant institutions to reconstruct the staging of masculinity in a way that accommodates gender equality.

Abstract

Budgeting is essential for organizational success, facilitating effective resource allocation, financial planning, and performance evaluation. Public Service Agencies (BLUs), notably higher education institutions, benefit from financial autonomy that allows flexible fund management to support institutional objectives. This study examines the implementation of Performance-Based Budgeting (PBB) at UPN “Veteran” Yogyakarta through a descriptive research design, focusing on processes, the relationship between budget allocation and institutional performance, and identifying challenges and opportunities. Findings reveal a significant increase in budget realization, rising from 78.2% in 2020 to 96.9% in 2023, positively influencing the attainment of several Key Performance Indicators (IKU). However, measuring budget allocations for individual IKU remains challenging due to overlapping activities that contribute to multiple indicators. This highlights the need for improved budgeting tools and tracking systems to strengthen the connection between expenditures and performance outcomes. The study underscores the importance of refining PBB practices to enhance resource utilization and align institutional performance with strategic goals in higher education

Abstract

Groundwater if the quality is not good if consumed will have an impact on health. The causes of poor groundwater quality include the value of Fe and Mn levels that exceed the established quality standards. Many methods can be done to overcome the quality of groundwater caused by high Fe and Mn levels, one of which is to use a ceramic membrane made from clay and kaolin with a variation of the coconut shell activated charcoal mixture in the composition of the ceramic membrane by 5%. 10% and 15%. The goal is to determine the effect of ceramic membranes with continuous flow systems on reducing content in clean water.  Results showed that the percentage of decrease in Fe and Mn content produced by variations in the composition of coconut shell activated charcoal of 0%, 5%, 10%, and 15% was, respectively for average Fe levels of 15.85%, 69.44%, 75.02%, and 80.83%, and for average Mn levels of 0.00%, 5.71%, 10.00%, and 18.67%. The best variation in the composition of coconut shell-activated charcoal in clay and kaolin-based ceramic membranes in reducing Fe and Mn content in clean water to meet the quality standards of coconut shell-activated charcoal composition by 15%. It is expected that this activity can be used as a basis for further development in groundwater treatment using ceramic membranes made from clay and kaolin with the addition of coconut shell-activated charcoal composition.

Abstract

SFRA (Sweep Frequency Response Analysis) is a transportation test where one of the purposes of this test is to ensure that the core of the power transformer does not shift due to the journey from the factory to the field. The SFRA testing is divided into 4 frequency range areas from 20 Hz to 20 MHz and this research is focused on the frequency range below 2 KHz, based on experience at this frequency to check transformer core problems and specific failures in shifting power transformer cores. Based on the comparison results of SFRA testing carried out at the power transformer factory during the FAT (Factory Assessment Test) with testing in the field during the first SAT (Site Assessment Test) and with the second SAT testing, there are differences in the frequency area below 2 KHz, this shows that there is a problem in the area power transformer core, before drawing a final conclusion that there is a problem or deformation in the transformer core, you must look at the results of other tests carried out in the field such as ratio test, winding resistance test, tangent delta test, excitation current test, insulation resistance (megger test). ) winding and core-frame as well as impact recorder data during the journey from the factory to the field. If all other field test results are good then the power transformer is still in good condition and ready to operate and the difference in the graph at a frequency of less than 2 KHz in the SFRA test during SAT compared to when FAT is likely to be caused by residual magnetism that is still on the core side due to testing. DC before or. Residual magnetism can occur due to static electrical phenomena due to the oil purification process or due to the induction effect of the network grounding system where the power transformer is placed
