Subjective Tendencies in Ibn Kaṡīr’s Exegesis: A Study of Narrative Selection and Interpretation in QS. al-Baqarah [2]: 21-22
Authors: Anshori Anshori
Published: August 2024

Ibn Kaṡīr’s approach to simplifying and expanding meaning through the citation of various riwayat suggests a subjective tendency in his interpretation. This study aims to uncover Ibn Kaṡīr’s subjective narratives by analyzing his selection and organization of riwāyah, comparing them to the interpretations of earlier scholars who followed similar criteria. The research employs a qualitative methodology, utilizing Julia Kristeva's intertextual analysis model, and focuses on the exegesis of QS. al-Baqarah [2]: 21-22. The study reveals that Ibn Kaṡīr utilized mechanisms of transformation, transposition, and opposition in relation to previous interpretations when explaining these verses. He appears to have distorted the meanings of existing narrations to support his own views, which can be observed in the way he adjusted certain narrations for use in his interpretative process. The variety of narrations provided by earlier scholars is summarized by Ibn Kaṡīr to align with his intended meaning. His selective presentation of certain narrations over others that have equal interpretative potential results in an identity of meaning consistent with his inclination towards Ibn Taymīyah’s interpretative approach. However, unlike Ibn Taymīyah, Ibn Kaṡīr tends to rely on favored narrations to establish a singular meaning. This subjective tendency influences the formation of an interpretative model that emphasizes a subject-object relationship, wherein the Qur'an's own context is overshadowed by the interpreter's will as a subject.
Objektivitas Riwayat dalam Tafsir Jāmi’ al-Bayān: Ekplorasi Formasi Diskursif aṭ-Ṭabarī
Authors: Faizah Thoriqotul
Published: August 2024

The debate surrounding the subjectivity in aṭ-Ṭabarī’s use of history in his work Jāmi' al-Bayān challenges the perception of its popularity as a widely-referenced tafsīr bi ar-riwāyah (interpretation based on narration). The assumption that aṭ-Ṭabari defended tradition in his Quranic interpretation process necessitates an exploration of the contextual factors shaping his discursive formation. This study aims to uncover the interconnections within this formation by employing qualitative methods supported by archaeological analysis. The findings indicate that the intense intellectual debates during the Abbasid caliphate’s knowledge advancements influenced aṭ-Ṭabari’s interpretive model. The rationalistic tendencies that began to permeate Quranic interpretation were countered by aṭ-Ṭabarī’s decision to rely exclusively on well-known narrations from the Companions and Tabi'in. This approach is reflected in the interpretation of various verses on a majority scale. The intensity of the debates during aṭ-Ṭabarī’s era not only impacted interpretive methods but also extended to legal rulings and theological beliefs, often using Quranic arguments. Aṭ-Ṭabarī's response to this dynamic involved an interpretive model that emphasized the preeminence (tarjīḥ) of specific traditions, revealing his subjective inclinations. Similarly, his approach to responding to fiqh and theological issues, which often involved syllogism and linguistic analysis, demonstrates a tendency to choose meanings while critiquing the interpretive products of various schools of thought, indicating an inconsistency with the school he ostensibly supported. This aspect reveals aṭ-Ṭabarī’s independence from the prevailing mainstream schools of his time.
Ketika al-Qur’an Bertemu Modernitas: Penerimaan Pemikir Kontemporer Islam dalam Konteks Kebebasan Beragama
Authors: Hakim Moh. Arif Rakman
Published: August 2024

The renewal concepts offered by contemporary Indonesian thinkers on actual issues involve legitimizing their views through the Quran. The approach of validating these issues, such as religious freedom, using various Quranic verses showcases a range of interpretations that can appear subjective and arbitrary. This research seeks to uncover the dialectical relationship between contemporary Indonesian thinkers, specifically Nurcholis Madjid, Abdurrahman Wahid, and Djohan Effendi, and the Quran, which forms a response of meaning to address current issues. Employing a qualitative methodology, the study utilizes Hans Robert Jauss’reception theory for data analysis. The findings indicate that the tendency to use the Qur'an in addressing actual issues is grounded in the compatibility of meaning, using the keywords within the verses that align with the issues being discussed. When suitable keywords are identified in a verse, they are interpreted with a dominance of the initial impression of understanding, primarily based on their linguistic meanings. This uniformity in meaning perception, which emphasizes objective meaning through language, is then applied to the contemporary context. The perception of liberal interpretation arises because the traditional interpretative moment, which mediates various perspectives of past interpreters, is often bypassed. As a result, these interpretative efforts cannot be fully categorized under the concept of contextual interpretation. However, the determination of objective meaning through textual analysis, extended to a new context that incorporates the subjective experiences of each thinker, makes this understanding mechanism not as subjective as commonly assumed.

Development of Maintenance Scheduling Model for the Safety Operational of Ship Machinery
Authors: Handani Dhimas Widhi , Uchida Makoto
Published: August 2024

Risk management of ship machinery is an important issue since machinery out of order can run into danger, especially for ships at sea. This paper implements risk based maintenance (RBM) to minimize the frequency and consequences of ship machinery failure. Not only the common steps of RBM, such as identification of problem, risk assessment, risk evaluation, and maintenance planning are conducted, but this paper also proposes a new model called ship position estimation. The preliminary identification i.e. identification of failure causes and symptoms as well as the history of failure time will be looked at first. In the risk assessment, quantification of the consequences of failure (Cof) considers system performance loss, while the probability of failure (Pof) is obtained from the reliability analysis of the failure time history. Risk evaluation compares the result of the risk assessment with the risk acceptance criteria in order to determine the level of risk. The proposed model of ship position estimation recognizes the ship position on the voyage when the analyzed machinery is in a high level of risk. Maintenance planning is further carried out to keep the machinery under the risk acceptance level. This paper utilizes a method called system dynamics to create simulation for each step of the RBM. As a case study, the parts of the pumps in the main engine cooling system are analyzed. The result of this paper is a proposed maintenance interval which is reasonable enough compared with the standard for pump maintenance. Additionally, the ship position is included when the pump reaches a high level of risk.

Addressing global issues like climate change requires transformative solutions, and the shipping industry is no exception. Moving towards emission-free ship design has become a critical need, offering a chance to significantly reduce greenhouse gas emissions from maritime transport. In 2018, the International Maritime Organization (IMO) adopted a bold strategy to cut these emissions by at least 50% by 2050. Embracing renewable energy sources like batteries, wind, solar, and hydrogen fuel cells is key to achieving this ambitious goal. While electric ships powered by batteries are pioneering the way, meeting the IMO's target will necessitate radical changes in future ship design. Here, Indonesia holds a unique advantage, the legacy of the Sriwijaya Empire renowned for its mastery of wind-powered ships, resonates with this emerging era of green shipping. Abundant sunshine, strong wind potential, and growing expertise in maritime engineering position Indonesia to become a leader in the development and deployment of sustainable ship designs. Harnessing these historical and contemporary strengths, Indonesia can play a pivotal role in revolutionizing the shipping industry. By fostering collaboration between policy makers, researchers, and shipbuilders, Indonesia can spearhead the transition to a future where cargo ships navigate the oceans propelled by the clean power of renewable energy, leaving behind a legacy of environmental stewardship and economic prosperity. This paper estimates the energy consumption and power needs of Container ships on short inter-island routes in Indonesia, with a particular focus on the potential application of batteries in such scenarios. The initial design utilizes similar vessel data collected from various locations around the world. Our findings indicate that a container ship operating on the Jakarta-Semarang route would require batteries with a capacity of 15.25 MWh, Semarang to Surabaya route would require 12.20 MWh batteries, from Surabaya-Tanjung Benoa Bali route required 15.25 MWh, from Tanjung Benoa Bali to Ujung Pandang route require 21.35 MWh batteries, all with a capacity of 1.5 MWh each and from Ujung pandang – Ibu Kota Nusantara require 18.3 MWh. These calculations assume normal sea and weather conditions and a design speed of 10 knots. Implementing battery-powered Containers on these routes reduces the CO2 emission into the air as long as the ship route operates.

Published: August 2024

Kawasan Alun-alun Kota Banyuwangi merupakan kawasan awal dalam morfologi kota Banyuwangi. Pada perkembangannya, kawasan ini memiliki kecenderungan menggantikan bangunan-bangunan lama dengan bangunan-bangunan baru. Tren ini mengakibatkan elemen persisten kawasan banyak yang bersandingan langsung dengan elemen-elemen baru. Hal ini membuat kualitas street front jadi beranekaragam dan fluktuatif. Padahal, kualitas street front merupakan salah satu pembentuk identitas dan karakter kawasan. Penelitian ini bertujuan untuk menelusuri tingkat kualitas street front di kawasan Alun-Alun Kota Banyuwangi, dan menganalisis pengaruh keberadaan elemen persisten terhadap kualitas street front, serta mengidentifikasi tipologi pada lapangan yang menghasilkan kualitas street front yang baik dan buruk. Penelitian dilakukan dengan analisis tipomorfologis urban tissue seluas 500x800m di sekitar Alun-alun Kota Banyuwangi. Proses penilaian kualitas street front menggunakan metode deskriptif kualitatif. Hasil penelitian menunjukkan adanya macam-macam tingkat kualitasstreet front pada kawasan. Kualitas street front yang paling banyak ditemukan adalah acceptable yaitu batas tengah. Kualitas terbaik sangatlah sedikit dan terletak di sekitar elemen persisten yang propelling. Sedangkan elemen persisten pathological cenderung memperburuk kualitas street front. Hal ini dikarenakan adanya upaya kolektif untuk menjaga dan merawat elemen propelling, sedangkan elemen pathological dan elemen baru cenderung tidak selaras perkembangannya. Setiap tingkatan kualitas street front memiliki tipologi masing- masing. Kualitas street front paling vibrant didapatkan ketika ada aktivitas yang meluber ke jalan, bangunan dan detail yang bisa dinikmati, skala koridor yang ramah pejalan kaki, fasad yang selaras, serta naungan dan area pejalan kaki yang jelas. Kualitas street front paling buruk ditemukan ketika skala bangunan menghimpit, tidak ada detail yang bisa dilihat, maintenance bangunan buruk, sampah yang berserakan, area pejalan kaki tidak terdefinisi, serta aktivitas manusia terbatas di sepanjang jalan.

Published: August 2024

Vegetable-based edible oil in Turkey is produced primarily from olive oil, as well as oils obtained from various plants such as sunflower, corn, cotton, poppy, soybean, safflower and canola which are also among the main food sources. The quality of the oils used in our diet is primarily determined by the ratios of saturated and unsaturated fatty acids. Another important feature that determines oil quality is primarily antioxidant activity and its other biological activity capacities. This study was carried out to determine the fatty acid profiles and antioxidant capacities of 17 (seventeen) different oils of vegetable origin, which are widely consumed in Turkey and have economic importance. Fatty acid compositions were determined with GC-MS method. Antioxidant activities of different edible oils were determined by using 2,2'-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity method. According to the results of this research, the highest scavenging effect was detected at different concentrations was obtained from soybean oil with 94.30±1.57%, while the least scavenging effect was obtained from peanut oil with 32.34±1.00%. Major fatty acid components linoleic acid (C18:2) and linolenic acid (C18:3) were detected in 17 different oils. Also, the presence of beta-sitosterol was examined by Thin Layer Chromatography and it was determined that beta-sitosterol was present in almost all of them.

Quality of Schooling, Fertility and Economic Growth
Authors: Saini Swati , Keswani Mehra Meeta
Published: August 2024

The existing body of literature underscores the crucial role of technology, driven by both innovation and imitation, in fostering economic growth. Human capital emerges as a key factor influencing technology adoption and innovation. We consider a R&D-based growth model to analyze how improvement in schooling quality impacts technical progress (via the twin channels of imitation and innovation) and therefore, long- run economic growth of an economy by working through the influence of fertility rates and education decisions at household level. The results indicate that improvement in schooling quality triggers a child quantity-quality trade-off at the household level when quality of schooling exceeds an endogenously determined threshold. At household level, parents invest more in the education of their children and have lesser number of children. This micro-level trade-off has two opposing effects on aggregate human capital accumulation at the macroeconomy wide level. A higher investment in education of a child stimulates the accumulation of human capital, which fosters technical progress, but the simultaneous decline in fertility rate reduces total factor productivity growth by contracting the stock of human capital. The former effect prevails over the latter only when quality of schooling is higher than the threshold and therefore, economic growth is driven by rate of aggregate human capital accumulation under both innovation and imitation regimes. However, when the quality of schooling is lower than this threshold, parents do not invest in education and focus on maximizing fertility. Therefore, the economy grows at the rate of population growth at the macro level under the two regimes. Also, it is advantageous for an economy to innovate upon the local technology frontier instead of imitating from the world technology frontier if the rate of human capital accumulation is higher than the growth rate of world technology frontier in the presence of constant or diminishing returns to R&D sector.
Human Crisis in Facing Emerging Fatal Pathogenic Microbes: The Hidden Obstacles
Authors: Ishida Morihito
Published: August 2024

The emergence of new and increasingly fatal pathogens presents significant challenges to global public health systems, and the intersection of human health and pathogenic microbes is a swiftly evolving area of concern. Continuous vigilance and preparedness in the presence of emergent infectious threats are underscored by the rapid spread of diseases such as COVID-19, Ebola, and Zika virus. Nevertheless, the effective battle against these fatal pathogens is significantly impeded by concealed obstacles, including misinformation/miscommunication, inadequate healthcare infrastructure in developing countries, and lack of funding for research, etc. A multifaceted approach is necessary to overcome these obstacles, which includes enhanced surveillance systems, public education campaigns on preventive measures, increased investment in research and development, and global collaboration to ensure the timely detection and response to emerging threats. We can only hope to mitigate the impact of fatal pathogenic microbes on human health and prevent future crises from unfolding by making a concerted effort to surmount these hidden obstacles.

Faulting, a critical distress in rigid pavements, poses a crucial challenge to road safety and maintenance. It is defined as the elevation difference of transverse joints in Jointed Plain Concrete Pavements, which is primarily caused due to environmental effects, subgrade properties, and accumulated traffic loads. Traditional regression models cannot often capture complex relations within pavement faulting and other detrimental effects on pavement, whereas Artificial Neural networks leverage data-driven machine-learning approaches to provide more accurate predictions. Datasets have been prepared from the LTPP database of dry climate zones. Environmental factors such as Yearly ESALs, Annual Precipitation, Annual Average Temperature, Freeze-Thaw Cycles, and structural properties like Pavement Thickness, Pavement Age, Tensile Strength, and Optimum Moisture Content (OMC) are considered the factors causing wheel path faulting. An Artificial Neural Network (ANN) based faulting prediction model is developed with one hidden layer and three neurons. 8 States over 30 years of lifespan are taken into consideration for this study. The final developed ANN model can predict the faulting in pavement sections accurately for any climatic region with an R2 value of 0.81. The correlation between the factors is studied as well and an ANN linear equation is also developed. The developed predictive ANN model equation will allow transportation engineers and contractors to easily predict Faulting in Jointed Plain Concrete Pavements (JPCP) which will assist in improving maintenance strategies to alleviate the effects of JPCP faulting.

Introduction: Schizophrenia is a mental disorder characterized by a breakdown in thinking, poor emotional responses, it burdens afflicted individuals, their families, and society. Expressed emotion refers to verbalization of strong feelings by patients of schizophrenia which often causes relapse. Objective: The main objective of this study was to assess the socio-demography of the primary care givers, the impact of emotional expression, and the association of emotional expression of primary care givers in relation to relapse rate on schizophrenic patients in a National Psychiatric Hospital. Methods: A Quantitative Descriptive Cross-Sectional Study was carried out to assess the level of expressed emotion of primary care givers towards schizophrenic patients at National Psychiatric Hospital in Asmara, from 17 November to 8 December 2016. Through face to face interview using structured (LEE-S) questionnaire. Result and discussion: The study included three hundred twenty-three participants who are adult primary care givers of the schizophrenic patients in National Psychiatric Hospital. Majority of the respondents 68 (55.28%) were males and 91(73.98%) of them were married. The study findings showed a positive correlation ( r= 0.288) and significant level of association ( p value =0.001) between expressed emotion level and relapse rate, indicating that high expressed emotion which means that most aggressive patients can experience relapse frequently compared to less aggressive patients who present with low expressed emotion. A significant association between the gender of primary care givers and expressed emotion (p- value = 0.006) was identified. Further to this, the study findings indicated that age, marital status, residence and educational level of primary care givers had no significant association with expressed emotion. A significant association between drug compliance and relapse rate of high expressed emotion was observed (p-value =0.026) indicating that higher relapse rate in those who had high expressed emotion. A significant association (p-value = 0.013) was found between attitude towards illness and relapse rate; whereas there was no any association between intrusiveness, hostility and tolerance, and relapse rate. Conclusion: This study concluded that high expressed emotion of primary care givers was found to have a positive significant association with relapse rate including the gender of primary care givers as well. The study further pinned down that, age, marital status, residence and educational level of primary care givers had no association with expressed emotion however still, there was a significant association between drug compliance and relapse rate of high expressed emotion. The following factors had an influence on this study, country climate, tradition, culture of the community caregivers as well as involvement of traditional remedies and practices towards schizophrenia.

Salah satu pencegahan yang dapat dilakukan dalam mencegah penyebaran Covid-19 adalah Perilaku Hidup Bersih dan Sehat (PHBS). PHBS merupakan semua perilaku kesehatan yang dilakukan karena kesadaran pribadi.. Kurangnya dalam melaksanakan PHBS menyebabkan santri menderita scabies, ISPA, gastritis, dan kecacingan.  Penelitian ini bertujuan untuk mengetahui gambaran PHBS santriwati pada masa pandemi di Pesantren X Kabupaten Bogor Tahun 2022.Penelitian ini adalah penelitian desain studi cross sectional dengan jumlah sampel sebanyak 278 santriwati yang diambil dengan metode random sampling. Kebiasaan PHBS pada masa pandemi yang dilakukan santriwati seperti cuci tangan pakai sabun (CTPS), penggunaan masker, jaga jarak, membuang sampah, penggunaan jamban, menggosok gigi, minum obat cacing dan aktivitas fisik ditanyakan melalui wawancara. Analisis variabel menggunakan distribusi frekuensi.Hasil penelitian menunjukan bahwa sebagian besar santriwati memiliki perilaku cuci tangan (50 %), penggunaan masker 51,4 %), jaga jarak (52,2%), perilaku membuang sampah (60,8%), managemen kesehatan menstruasi (60,8%), penggunaan jamban (66,5% %), menggosok gigi (53,2 %,), perilaku minum obat cacing (53,2 %,) dan aktifitas fisik (59%) yang tergolong baik. Namun diantara perilaku tersebut, perilaku CTPS memiliki persentase terkecil yaitu sebesar 50 %. Perilaku CTPS ini sangat berisiko dalam penyebaran Covid-19 dan juga penyakit infeksi lainnya. Dengan demikian diperlukan kebijakan dari pengurus Pondok Pesantren terkait pengawasan perilaku CTPS para santriwatinya

Published: August 2024

Investors in the BRIC countries have found the tough line of attack that economic development may not convert into stock market gains, and several analysts criticize problems with corporate governance in Russian and Chinese markets. Against this milieu, the purpose of this paper is to develop and examine the conditional volatility models in an attempt to confine the prominent features of volatility in stock markets in BRIC countries. A popular econometric technique namely TGARCH models has been employed to study the behavior of volatility of Stock markets in BRIC Countries. Results reveal that India reflects a high degree of volatility of series returns among the BRIC countries. Although the Indian stock market has extended its operation in the post-liberalization era, about volatility the market has not established any significant transform. This long-lasting volatility in the stock market has been a disappointing issue for retail investors to invest in equity markets. Due to high volatility, new clients are afraid to burn their fingers and existing investors are uncomfortable in roiling their portfolio in India. The social cost connected with high volatility was heavy. Authentic investors lost buoyancy and departed from the market. Credit rating agencies act as a driver of stock market volatility.
