Abstract:This study aims to analyze the relationship and influence of coal quality parameters which include Total Moisture (TM), Ash Content (ASH), and Total Sulfur (TS) on Gross Calorific Value (GCV). The data used in this study…
is data from laboratory tests on 23 samples of Run Of Mine (ROM) coal at seam 16 at PT Unggul Nusantara, North Barito Regency, Central Kalimantan. Data analysis was performed statistically using the help of SPSS software through Pearson correlation test and multiple linear regression analysis. The results of the correlation test showed that simultaneously, the TM, ASH, and TS parameters had a very strong relationship with the GCV value with a correlation coefficient (R) of 0.893 and contributed an influence of 76.5%. Partially, Ash Content (ASH) had a very strong negative relationship (r = -0.881) and had a significant effect on calorie values (p = 0.000). Each 1% increase in ash content would decrease the GCV value by 68.249 Kcal/Kg. Meanwhile, Total Moisture had a significant positive relationship by simple correlation (r = 0.506, p = 0.014), but showed no partial significant effect in multiple regression models (p = 0.364). Total Sulfur was found to have a very weak negative relationship (r = -0.182) and had no significant effect on GCV values (p = 0.406). This study concludes that Ash Content is the most dominant parameter that affects the reduction of the caloric value of coal seam 16 at PT Unggul Nusantara.

Abstract:Direct incentive programs from a brand manufacturer to a distributor's sales force are uncommon in the Indonesian B2B lighting sector, and their consequences for portfolio composition and distributor profitability have not…
ot been empirically tested. This study examines whether a flat 3 percent quarterly bonus, applied uniformly across a portfolio of more than three hundred products spanning a 600-fold price range, produces unintended consequences beyond its stated goal of volume growth. A sequential explanatory mixed-methods design is used. The quantitative phase analyses 781 product-quarter observations covering 326 products over eleven quarters from mid-2023 through end-2025. The qualitative phase uses confirmatory interviews with seventeen informants from distributor management and sales teams. The incentive program successfully drives all four sales performance dimensions measured in the study, covering volume growth, revenue share, transaction frequency, and a cumulative growth index, all of which are statistically significant. However, higher-priced products attract significantly fewer transactions per quarter and grow more slowly over time. Seven of eight hypotheses are supported. Qualitative findings confirm that the incentive effect adds to total selling activity rather than redirecting it, but transaction attention consistently concentrates on lower-priced products across the eleven-quarter period. The study extends agency theory to a three-party setting and provides the first panel-level evidence of composition effects from a uniform sales incentive in Indonesian B2B distribution.
Abstract:Islamic economics operates as a normative framework prioritizing social justice, equitable wealth redistribution, and collective wellbeing. Despite its robust philosophical foundations, empirical consensus regarding how…
these tenets translate into measurable welfare outcomes across heterogeneous developing nations remains highly fragmented. This study addresses this critical gap by executing a systematic literature review guided by the PRISMA 2020 statement to synthesize empirical evidence on the operationalization of Zakat, Waqf, and Islamic Social Finance (ISF) as structural instruments for poverty reduction. Departing from traditional descriptive reviews, this paper introduces an original analytical taxonomy that maps the operational mechanics of ISF against micro-level and macro-level development outcomes. Based on a rigorous multi-stage screening of peer-reviewed empirical studies published between 2020 and 2025 across emerging economies, a final synthesized sample of $n = 10$ high-quality primary articles was evaluated. The qualitative narrative synthesis reveals that integrated ISF instruments exert a structurally positive impact on poverty alleviation, income optimization, and socio-economic empowerment, particularly when embedded within digital financial ecosystems and formal financial inclusion frameworks. However, the analysis uncovers substantial outcome heterogeneity, demonstrating that welfare efficacy is highly conditional upon institutional governance quality, targeting accuracy, and localized implementation designs. The structural novelty of this research lies in its empirical crystallization of the explicit boundary conditions under which normative faith-based capital successfully disrupts poverty traps, offering an evidence-based operational blueprint for policymakers and Sharia social institutions in the Global South.
Abstract:This study aims to analyze the concept and application of hospital criminal liability in cases of medical malpractice in the Indonesian criminal law system, as well as examine the relationship between the individual responsibility…
onsibility of medical personnel and the responsibility of hospital institutions. This study uses a qualitative approach with case study methods and a juridical-normative approach enriched with empirical data. Data was collected through in-depth interviews with legal practitioners, medical personnel, and hospital managers, accompanied by a documentary study of laws and regulations, court rulings, and related literature. The results of the study show that criminal liability in cases of medical malpractice is generally still focused on individual medical personnel as direct perpetrators, while the accountability of hospital institutions has not been optimally applied in criminal law enforcement practices. In addition, it was found that there is a complex relationship between the professional responsibilities of medical personnel and the institutional obligations of hospitals in ensuring health service standards, including aspects of supervision, risk management, and medical service systems. This study concludes that it is necessary to strengthen the concept of corporate criminal liability for hospitals in cases of medical malpractice in order to create legal certainty and more balanced protection for patients, medical personnel, and health service institutions. The findings of this study contribute to the development of health law studies and become a basis for consideration for policymakers in formulating more effective regulations and law enforcement mechanisms.
Abstract:This study aims to reveal the relationship between the values contained in the Qur'an and the traditional practice of dowry (mahr) giving, viewed from both religious and cultural perspectives. Using a qualitative approach…
h based on the textual analysis of Qur'anic verses and in-depth interviews with experts in religious studies and cultural anthropology, this research integrates the frameworks of maqasid al-sharia and cultural anthropology theory to analyze the historical and contemporary transformation of dowry practices. The study also explores the symbolic meaning of dowry, not merely as an obligation but as a form of recognition of women's dignity and rights within the family. Furthermore, it examines the socio-economic factors influencing the amount of dowry and how these factors affect social structures and gender relations within society. In addition, comparisons are made with dowry practices in various other cultures and religions, enabling a deeper understanding of both the unique and shared aspects of universal human values. This comprehensive analysis seeks to provide new insights and a concrete contribution to contemporary discussions on the role of religion in social and cultural life, as well as the challenges of integrating tradition with the needs of modern society. The findings indicate that the practice of dowry giving, as prescribed in the Qur'anic verses, possesses profound normative and strategic values in ensuring justice and social balance within the family structure. Every element of the dowry is not merely symbolic but also embodies meanings that reflect responsibility, respect, and commitment in married life. Over time, the understanding and implementation of this tradition have undergone significant changes, influenced by evolving social, economic, and cultural conditions. This highlights the importance of not only preserving the tradition but also adapting it to meet the demands of contemporary society.

s, as well as its arrangement in the Compilation of Islamic Law (KHI) in Indonesia. The method used is normative legal research with statutory and conceptual approaches, referring to authoritative classical tafsir and fiqh works such as Jami' al-Bayan by al-Tabari, al-Jami' li Ahkam al-Qur'an by al-Qurtubi, Tafsir Ibn Kathir, al-Umm by Imam al-Shafi'i, and al-Mughni by Ibn Qudamah, as well as contemporary works such as Fiqh al-Sunnah by Sayyid Sabiq and the works of Wahbah al-Zuhaili and Yusuf al-Qaradawi. The findings indicate that classical jurists unanimously prohibit the marriage of a Muslim woman to a non-Muslim man and the marriage of a Muslim man to a polytheist (mushrik) woman, but differ regarding the marriage of a Muslim man to a woman of the People of the Book (Ahl al-Kitab). Meanwhile, the KHI takes a stricter stance by prohibiting all forms of interfaith marriage, in line with the principle of preventing harm (sadd al-dhari'ah) and the MUI Fatwa of 2005. This study concludes that the KHI represents a contextualization of fiqh adapted to the conditions of Indonesian society.
Abstract:Halal certification has become an essential mechanism for ensuring that products meet Islamic requirements while also maintaining standards of safety, quality, and consumer protection. Despite its growing importance, awareness…
reness and understanding of halal certification remain relatively limited among community members, particularly women who play a central role in household purchasing decisions. This community engagement initiative was designed to enhance the knowledge and awareness of members of the Family Welfare Empowerment Organization (PKK) in Sidodadi Village, Kedaton District, Bandar Lampung City, regarding the significance of halal certification in consumer products. The program engaged 30 participants and applied a participatory educational approach consisting of counseling sessions, interactive discussions, lectures, and question-and-answer activities. Knowledge acquisition was evaluated through pre-test and post-test assessments. The findings demonstrated a marked improvement in participants’ understanding, with average scores increasing from 51.3% prior to the intervention to 94.0% afterward. The program not only strengthened participants’ awareness of halal-certified products but also encouraged more informed and responsible consumption practices. These results highlight the effectiveness of community-based halal literacy initiatives in fostering greater public understanding and supporting the development of a halal-conscious society.

er distribution and its impact on rice productivity in the tidal lowland areas of Tanjung Lago District, Banyuasin Regency. The research employed both quantitative and qualitative descriptive approaches using a stratified random sampling method involving 60 farmers who received subsidized fertilizer and 30 farmers who did not reveive subsidizer fertilizer. The effectiveness of subsidizer fertilizer distribution was evaluated using a likert scale based on the Six Appropriateness Principles, while the impct on rice productivity was analyzed by comparing the productivity levels of the two farmer groups. The findings showed that the distribution of subsidized fertilizer was generally categorized as moderately effective, with an average effectiveness score of 71,33%. The price compliance indicator was classified as highly effective (91,66%), while location suitability was categorized as effective (81,00%). Meanwhile, quantity appropriateness, fertilizer type suitability, and timeliness of distribution were categorized as moderately effective. The findings showed that the distribution of subsidized fertilizer was generally categorized as moderately effective, with an average effectiveness score of 71.33%. The price compliance indicator was classified as highly effective (91.66%), while location suitability was categorized as effective (81.00%). Meanwhile, quantity appropriateness, fertilizer type suitability, and timeliness of distribution were categorized as moderately effective. In contrast, the fertilizer quality suitability indicator was still considered ineffective, with an effectiveness score of 55%. The use or subsidized fertilizer also contributed positively to rice productivity. Farmers receiving subsidized fertilizer achieved an average rice productivity of 3.77 ton ha⁻¹, whereas farmers who did non receive subsidized fertilizer produced an average productivity of 3.20 ton ha⁻¹. This resulted in a productivity defference of 0.57 ha⁻¹.. equivalent to approximately 17.81%.
Abstract:This study examines the visual symbols and cultural values contained in the Marhum Pekan Tomb, one of the historical sites inherited from the Siak Sri Indrapura Sultanate which is the cultural identity of Pekanbaru City.…
City. The purpose of this study is to reveal the meaning, philosophical values, and forms of acculturation of Islamic culture with local Malay traditions represented through the physical form and ornamentation of the tomb. This study uses a qualitative descriptive method with Erwin Panofsky's iconographic approach which includes three stages of analysis, namely pre-iconography, iconography, and iconology. Data sources were obtained through field observations, in-depth interviews, as well as literature and documentation reviews. The results of the study show that visually (pre-iconography), the Marhum Pekan Tomb displays the architectural characteristics of the Selaso Jatuh Kembar House, the use of Malay regalia, stepped jirat forms, and headstones with gender-differentiating shapes, all of which are a blend of local and Islamic culture. Based on the iconographic analysis, all ornaments in the form of plant and flower motifs contain symbolic meanings of purity, fragrant names, good deeds, and obedience to Islamic teachings that prohibit the depiction of living creatures. Meanwhile, iconological analysis reveals the fundamental meaning that this tomb complex is a tangible manifestation of the Malay people's philosophy of life, namely "Adat bersendi Syarak, Syarak bersendi Kitabbullah". The tomb of Marhum Pekan is not merely a burial place, but also evidence of the history of Islamic-Malay civilization and the collective memory of the community, which confirms that the development of Pekanbaru City grew and developed on a foundation of religious values and harmonious local cultural wisdom.
