THE RELATIONSHIP BETWEEN SCIENCE AND DEMOCRACY ON PHILIP KITCHER’S PERSPECTIVES
Authors: Islami Moch Zihad , Muthmainnah Lailiy
Published: December 2023

The relationship between science and democracy has been an interesting and important issue in the study of philosophy as well as political science. Democracy does not only apply in the political realm but can also be seen in the context of science. This paper uses a political-philosophical approach to explore the relationship between science and democracy from the perspective of Philip Kitcher. As far as the philosophical research model used in this research is the concept of figure thinking by using primary sources in the form of Philip Kitcher's two main works among other works, namely: Kitcher's Science, Truth, and Democracy (2001) and Science in a Democratic Society (2011), as well as secondary sources such as books, journal articles and sources relevant to the concepts of the relationship between science and democracy. This paper concludes that the relationship between science and democracy according to Kitcher is based on the concept of a partnership model. This model emphasizes that scientists should consider how knowledge can be applied in a social and practical context, as well as enabling the active participation of the public democratically in the process of scientific research. The relationship between science and democracy, according to Kitcher, relates to the epistemological and socio-practical significance to be taken into account in scientific decision-making, as well as taking into account the public perspective in decision-making. In Kitcher’s perspective too, integration between science and democracy became essential to forming a normative framework for more transparent, democratic scientific research, and producing high-quality knowledge.
EXISTENTIAL-PHILOSOPHICAL SYMBOLS AND MEANINGS IN THE SUFISTIC ROMAN “GHURBAH AL-GHARBIYAH” SUHRAWARDĪ
Authors: Rohim Lukman Hakim
Published: December 2023

Suhrawardī, as the founder of illumination philosophy, has works in the field of literature that have philosophical nuances. Researchers through this article attempt to examine philosophically-hermeneutically the Sufistic Romance of Ghurbah al-Gharbiyah Suhrawardī which has not been extensively studied by researchers including Suhrawardī scholars. The novel is genealogically related to Ḥay bin Yaqẓān by Ibn Sīnā and Ibn Ṭufayl, so it is called the Ḥay bin Yaqẓān trilogy: Avicenna, Ibnu Ṭufayl, and Suhrawardī. Through Ricoeur’s Hermeneutic Approach and Corbin’s Epistemology of Sufistic Imagination, which is used as a research method, researchers intend to interpret the symbols and existential meanings of Ghurbah al-Gharbiyah's novel. The purpose of this study is to interpret the background, symbols, and meaning behind Suhrawardī’s novel. The conclusion of this study: Ghurbah al-Gharbiyah discusses the philosophical theme of human alienation in the world with the use of symbols: the city of Qairawan as the imprisoned phase, the Hudhud bird as the enlightenment phase, and the journey on Mount Sinai during the liberation phase and meeting with the "Light of all Lights". Three phases each characterize today's Sufistic consciousness of man: the experience of alienation, enlightenment, and liberation. On the other hand, this novel is a representation of Suhrawardī's subjective creative imagination (al-quwwah al-khayāliyyah) inspired by prophetic experiences: Prophet Muhammad's Ascension, Prophet Sulaiman's Hudhud bird, and Prophet Musa's Mount Sinai.
EPISTEMOLOGY METHODOLOGY OF IMRE LAKATOS'S SCIENTIFIC RESEARCH PROGRAM AND CONTRIBUTION TO ISLAMIC SCIENCE
Authors: Fadli Muhamad
Published: December 2023

Abstrak (Indonesian): Penelitian ini memiliki tujuan untuk melihat lebih jauh terhadap proses riset ilmiah dalam keilmuan Islam dari kacamata Program riset Imre Lakatos. Penelitian ini menggunakan pendekatan kualitatif dengan metode kepustakaan atau library research yakni menelusuri tulisan-tulisan yang memiliki keterkaitan dengan tema yang diangkat baik berupa buku maupun artikel-artikel terbaru yang relevan. Hasil dari penelitian ditemukan bahwa Program riset ilmiah Imre lakatos merupakan hasil dari pengembangan pendahulunya yakni falsifikasi Popper dan revolusi Ilmiah Thomas Kuhn. Falsifikasi Popper dengan membuktikan kesalahan teori dibantah oleh Kuhn dengan konsep paradigma dan revolusi ilmiah. Jika falsifikasi membuang teori yang terbukti kesalahannya maka revolusi ilmiah menjadikan paradigma lama (teori ter-falsifikasi) sebagai pijakan untuk menemukan kebenaran baru (paradigma baru) Riset Ilmiah ini memiliki tiga elemen penting: 1) hard-core, merupakan inti dari sebuah riset yang tidak bisa diganggu; 2) protective-belt, yang berusaha untuk melindungi hard-core supaya tidak tereliminasi: dan 3) a series of theory, yang memuat teori yang saling berkaitan dan akan melahirkan teori yang baru. Dalam keilmuan Islam juga berlaku peristiwa serupa, bedanya dalam keilmuan Islam sekompleks apa pun permasalahannya, hard-core tidak akan pernah bisa tergantikan. Berbeda dengan program riset Lakatos yang menyesuaikan dengan konteks permasalahan. Salah satu buah dari konsep Lakatos adalah hadirnya paradigma Integrasi-Interkoneksi yang digagas oleh Amin Abdullah di UIN Sunan Kalijaga. Tujuannya ingin menghubungkan ilmu agama dengan ilmu-ilmu lainnya tentu dengan melaksanakan riset-riset. Karena dalam Islam hard-core (Al-qur’an dan Hadist) berlaku selamanya untuk semua permasalahan hidup, maka sangat mungkin hard-core Islam di lakukan koneksi dengan ilmu lainnya untuk menemukan solusi atas permasalahan yang akan datang.
PHILOSOPHICAL REFLECTION ON THE INTERCONNECTION OF LIFE, RELIGION, AND HISTORY

Published: December 2023

Our life and religion always need history, but how historical experience leaves messages, understood and written, and obtains the status of historical truth is a fairly long discussion. History/historical writing is the relationship between the author (subject) and object (historical events/facts). This relationship is a dialectical relationship that influences the elements of truth because like it or not, humans are historians and the writing of history is directed by the individual of its recorder. It is often said that history is written by the victorious groups. By using a critical approach, structuralism (Michel Foucault), to look at episteme (suppositions and principles that unconsciously influence history and historical writers, as well as systems of thought that direct how to practice science in an era), through structuration (Antony Gidden), which shows how the structure of society and activities including writing are formed, where these conditions play a role in a discourse and determine how a discourse occurs. constructivism (J. Piaget), which directs the human way of thinking from assimilation, accommodation, and equilibrium, as well as the subjective-objective approach (philosophy), and phenomenology from Heidegger and others, to reveal the structure of know and human knowledge, thus revealing the dialectic of neurotic and its neomatic elements, elements as ‘wesen’, essence, of the true history. In conclusion, even though history is written subjectively (the human element with its history) with a subjective-objective approach, you will get history or historical writing that is quite accountable and valid. Furthermore, the hope is to present objective (Islamic) history (Islam that is generally accepted, not just because of faith, but more in a rational-objective direction) with quite valid historical evidence.

Children who are different from other kids their age or from kids in general are known as children with special needs, or ABK. The process of growth and development, which entails deviations or abnormalities on all fronts—physically, cognitively, intellectually, and socially—is one way in which these disparities appear. The findings of an investigation at SLB C-YPSLB Surakarta revealed issues with intellectual impairment and mobility disorders. When it comes to the quality of physical activity for children with mental retardation who require specialized instruction and supervision, motor development is a crucial factor. The fulfillment of physical needs is also impaired, namely sensorimotor skills, body balance, the ability to recognize the environment, body coordination and mobility, and body flexibility. Gymnastics for Children with Special Needs (ABK) was chosen as a solution to improve their motor skills. The chosen method is doing gymnastic movements together and guided by physiotherapy. Gymnastics has important benefits for health, child development now and in the future. Other benefits include strengthening children's muscles, bones and heart, as well as improving children's coordination, balance, posture and flexibility to achieve a better quality of life.

Kelompok Wanita Tani (KWT) Nira Lestari is a micro, small and medium enterprise (MSME) engaged in coconut processing, including Virgin Coconut Oil (VCO). VCO products produced by partners have low quality and quickly smell rancid. These problems are caused by the manual production process which causes a long production time, the inclusion of water that causes hydrolysis and the high volatile compounds in VCO. The purpose of this program is to design a centrifugation device and vacuum pump filter to increase the efficiency of partner production and eliminate rancid odor in the VCO produced. The method used in this service is a survey of partner needs, tool design, tool making, tool testing, tool application and product testing. The application of the two tools has been proven to help streamline partner production and eliminate rancidity. Laboratory test results of VCO after the use of the tool show that VCO has a moisture content of 0.0829% and a germ content of 0%.

No Brasil, o estudo da condição de legitimidade (filiação) é tópico que vem sendo tratado pela literatura especializada, tanto no âmbito da História quanto no da Demografia Histórica, sobretudo a partir da década de 1980. O objetivo deste artigo é contribuir para o avanço da temática, mapeando a incidência e a distribuição espacial da ilegitimidade no estado de São Paulo, no final do século XIX, a partir de uma perspectiva diferente daquela dos estudos já elaborados, especialmente em relação ao recorte temporal e às fontes utilizadas. Assim, foram analisados os dados sobre a filiação na população paulista a partir dos Recenseamentos Gerais da População Brasileira, realizados em 1890 e 1900, acrescidos de outras fontes de cunho estatístico, produzidas para o estado de São Paulo. Os resultados apontam um quadro diferenciado em relação às várias zonas que compõem o estado e, embora as fontes sejam distintas, corroboraram o papel fundamental da imigração internacional, pois, nas áreas onde ela foi mais intensa, verificou-se a queda nos percentuais da ilegitimidade.

Published: December 2023

Several methods to enhance heat transfer can be classified into three categories: active, passive, or hybrid. Among these methods, Vortex Generators (VGs) are one passive heat transfer enhancement device widely used in heat exchangers. This study aims to explore the geometric shapes of VGs equipped with longitudinal holes and examine their influence on the outlet temperature of the fluid. For the analysis in this research, a three-dimensional Computational Fluid Dynamics (CFD) simulation using ANSYS Fluent software was employed. The increased heat transfer and flow resistance in the VG geometry were evaluated based on previous research for validation. The study results demonstrate that the simulation produces fluid outlet temperature values and velocity contours that closely resemble the results obtained from the reference study. The validation error of this research was found to be only 0.02%, indicating high-quality and accurate simulation results. Furthermore, the study compared various geometries of the VG holes in the system. Among these geometries, hexagonal-shaped VG holes exhibited high-velocity contours on the VG side while achieving the lowest fluid outlet temperature at approximately 303.53 K. The findings of this study serve as a basis for further developments in enhancing the efficiency and performance of heat exchangers using VGs.

Published: December 2023

As a country along the Pacific Ring of Fire, Indonesia faces various natural disaster threats, including tsunamis. Therefore, an early tsunami warning system is crucial for detecting potential tsunami waves. The early tsunami warning system encompasses several complex components, one of which is the Ocean Bottom Unit (OBU) floater. This paper discusses the performance of various types of floater arrays for tsunami early warning systems using Computational Fluid Dynamics (CFD) simulations. The study focuses on coefficients, especially the drag coefficient, and the influence of the number of float arrangements on the flow pattern around the buoy or Ocean Bottom Unit (OBU) array. Among the five numerical simulation models, the six-couple floater has the highest drag and lowest lift coefficients, while the single floater has the lowest drag coefficient. The percentage of difference in drag coefficient between single floater and couple series floater is quite significant, reaching up to 50%. The moment coefficient is also affected by the number of floaters, with a series of five couple floaters having the highest moment coefficient at a Reynolds (RE) number of 2 × 106. The advantage of using the CFD method is that it can visualize current velocity, which is crucial for understanding the flow pattern around the float system. The results indicate that the flow pattern becomes more complex as the number of floater arrays increases, which leads to more vortices between the floater, resulting in increased turbulence and drag coefficient.

Published: December 2023

The project planning process, especially in ship repair projects, is essential to improving project completion. Ineffective planning of ship repair projects results in a lack of time and labour efficiency. Therefore, using project acceleration tools in scheduling ship repair activities is crucial to accelerate project completion and mitigate risk analysis of delays for each project activity. This research uses the critical path method (CPM) to analyze the main schedule of three combined ship repair projects. Then, shop-level planning is used to determine the productivity of each workshop so that each workshop knows the volume of work that needs to be completed daily. Furthermore, fuzzy logic is applied to analyze the risk of delays in repair project activities. The addition of working hours to critical work activities is accelerated from 30 days, the normal duration, to 23 days. Meanwhile, the addition of the workforce to critical work activities is accelerated from 30 days, the normal duration, to 22 days. The analysis of productivity values in each workshop results in the following productivity values: sandblasting and painting workshop 309.97 m2/person-days, piping workshop 4.12 units/person-days, fabrication workshop 407.16 kg/person-days, outfitting workshop 14.8 units/person-days, tank cleaning workshop 114.36 m3/person-days, and machining workshop 2.7 units/person-days. The fuzzy logic analysis results to determine the risk of delays in critical activities show that jobs with the codes SP1, SP2, SP3, SP4, M2, and SP5 have a high risk of delay. Additionally, the collaboration with other departments in the company, such as the marketing, finance, and human resources departments, is ongoing to complete assigned tasks.

Published: December 2023

As the demand for lightweight ships continues to rise, there is a growing necessity to explore innovative methods that can reduce the weight of ship structures without altering the materials used. This research addresses this challenge by investigating the effect of opening in stiffener under impact loading. The research aims to provide valuable insights into optimizing weight reduction strategies while ensuring the ship's overall strength and performance remain uncompromised. To achieve this goal, the study employed the finite element method as a solver. By simulating impact scenarios and analyzing stiffener responses, the numerical analysis quantified the structural behavior and failure modes. The focus was on understanding the impact of openings on the structural integrity and how it relates to their positioning relative to the impact point. The results of the study indicate that opening slightly distant from the impact point exhibit greater strength, showcasing a counterintuitive relationship between opening placement and structural response.
The Francovich Principle as the Basis of State Responsibility for Laborer Loss Due to Company Bankruptcy
Authors: Widyantoro Agus , Taufiqurrohman Moch. Marsa , Nugraha Xavier
Published: December 2023

The absence of legal certainty in the application of the pari passu pro rata parte principle in the distribution of bankrupt accounts in Indonesia has given rise to uncertainty regarding the protection of the rights of laborers whose employers or companies have faced bankruptcy. This article considers that Indonesia requires a set of formulations enabling the state to provide legal protection for the rights of laborers affected by employer or company bankruptcy. The article explores the feasibility of adopting the Francovich Principle in Indonesia, defining it as a principle holding the state accountable for the losses incurred by laborers due to company bankruptcies.  The  article  concludes  that  several  conditions must be met to apply the Francovich Principle, including the establishment of a guarantee institution, the obligation for financial contributions from companies, and the implementation of specific measures to prevent abuse. The state’s effort to adopt the Francovich Principle involves establishing a priority scale in drafting laws related to the Francovich Principle into the Priority National Legislation Program. Furthermore, the government needs to revitalize institutions related to the Francovich Principle within the national legal and regulatory system

Para ello, se atiende a los contextos, también a las relaciones del valido con los miembros del Consejo de Indias y finalmente a los argumentos que esgrimieron los consejeros para oponerse al proyecto de Lerma. Así, este estudio muestra e interpreta las nuevas vías exploradas por el valido de Felipe III para acrecentar la venalidad americana y la bolsa del rey.
La generalización de la hidalguía en la montaña Leonesa
Authors: Sánchez Badiola Juan José
Published: December 2023

Analizamos en este trabajo uno de los fenómenos más característicos y complejos de la nobleza española, cual es su práctica generalización en algunas regiones del norte peninsular, concretamente en la Montaña leonesa, cuyo prestigio entre los cronistas y reyes de armas, como origen y marchamo de hidalguía, es bien conocido. Pese a ello, es asunto poco atendido por la historiografía, lo que justifica, a nuestro parecer, el presente artículo, en el que nos ocuparemos de sus orígenes y desarrollo a lo largo de la Baja Edad Media y la Moderna.
De la sastrería al marquesado: el ascenso intergeneracional de la familia Uribe a través del comercio y la milicia (siglos XVI-XVIII)
Authors: Martínez Martínez Jose A.
Published: December 2023

El principal objetivo de este artículo es analizar las estrategias y los procedimientos de promoción social en el periodo moderno a través del ejemplo concreto que nos proporciona la familia Uribe, marqueses de San Mamés de Aras. El ascenso social de esta familia -originaria de la anteiglesia de Bedarona (Vizcaya) y asentada en Lequeitio, Sevilla y Caravaca- llegaría fundamentalmente a través de dos vías principales: el servicio militar al monarca y el enriquecimiento con las actividades comerciales y contrabandistas con las Indias. Estamos ante un proceso de ascenso gradual e intergeneracional, estructurado en torno a la renovación periódica de la red relacional familiar, que permitió a la familia pasar por todos los peldaños del escalafón nobiliario en poco más de dos siglos: infanzonía, hidalguía, caballería, señores de vasallos y nobleza titulada.
Un prohombre del porvenir agroindustrial aguilarense: Manuel Aragón Calvo de León (1879-1924). Aproximación a su semblanza
Authors: Galisteo Martínez José
Published: December 2023

El presente trabajo se ocupa de la aproximación biográfica de unos de los hacendados más importantes de la Campiña Sur cordobesa durante el primer tercio del siglo XX: Manuel Aragón Calvo de León (1879-1924). En su persona se aglutinaron una serie de factores que propiciarían un nuevo modelo de labrador, pues sus iniciativas propiciaron una evolución empresarial dentro del sector agropecuario, mostró un acercamiento hacia los incipientes compromisos sindicalistas del momento, asistió a cuantas causas religiosas y benéfico-asistenciales quedaron a su alcance, mientras que, en materia artística, fue partidario del estilo regionalista o «estilo sevillano» con la construcción de su casa-palacio en una de las calles principales de su localidad natal.
El manuscrito 22846 de la Biblioteca Nacional de España: el Libro Verde de Aragón
Authors: Combescure-Thiry Monique
Published: December 2023

El Libro Verde de Aragón se difundió en forma manuscrita alrededor de 1560 en la sociedad aragonesa, cuyos miembros más encumbrados desacreditaba. En efecto, sus genealogías revelaban, a plena luz, su origen judío en una época en que ciertas funciones estaban reservadas a los únicos candidatos que podían probar su limpieza de sangre (sin antepasados judíos o moros). Varios de estos libelos han llegado hasta nosotros y estudiamos aquí uno de ellos: el Manuscrito 22846 de la Biblioteca Nacional de España. Es el más voluminoso de todos los que conocemos hasta hoy. A consecuencia, aparecen en él personajes nuevos y a veces famosos: Ruy Gómez de Silva, Juan Pérez de Oliván, Zurita, Antich de Bages, doña Juana de Pernstein, duquesa de Villahermosa, y la emperatriz doña María de Austria, hermana del rey Felipe II.
De élite militar a élite político-económica: actividades económicas y redes clientelares del cuerpo de los Jenízaros en el Imperio Otomano del siglo XVIII
Authors: Calcara Eros
Published: December 2023

Durante el siglo XVIII, los jenízaros empezaron a labrarse un papel de primer plano en la sociedad otomana. El objetivo de este artículo es analizar las actividades de los jenízaros en el siglo XVIII, comparada con el análisis de fuentes archivísticas e historiográficas, fuera del contexto bélico. En primero lugar serán analizados las actividades económicas de los jenízaros, en segundo lugar, las relaciones con los gremios de artesanos, que los milicianos construyeron en el siglo XVIII. El análisis de los documentos del Archivo del primer ministro Otomano/Başbakanlık Osmanlı Arşivi (BOA) revelará primero cómo los jenízaros se habían convertido en un polo económico; y, en segundo lugar, cómo las funciones desempeñadas por los jenízaros, fuera de los campos de batalla, les han permitido siempre jugar un papel fundamental dentro de la vida urbana del Imperio Otomano.
Los albores del proceso inquisitorial contra Pablo de Olavide: la Inquisición de Corte, Sevilla y la Sumaria de Córdoba (1766-1775)
Authors: Moreno Martínez Álvaro
Published: December 2023

El litigio al que se ve sometido Pablo de Olavide por la Inquisición española será el último gran proceso del Santo Tribunal eclesiástico. En este trabajo abordamos el inicio de las hostilidades secretas emprendidas por el Santo Oficio, siguiendo como fuente principal las primeras delaciones de los testigos que declaran en sus causas abiertas en la Inquisición de Corte en Madrid y Sevilla, así como la primera Sumaria elaborada en la sede inquisitorial de Córdoba. Esta nueva fuente nos ha permitido identificar, analizar y comparar los testimonios de los testigos de esta primera arremetida del Santo Oficio para determinar las fechas exactas de las primeras acusaciones y los motivos que aluden, así como sus principales protagonistas, poniéndose al descubierto la existencia de una conspiración, en la que se entremezclan intereses políticos con personales. El objetivo de derrocar al señor de Sierra Morena, finalmente no se cumplió… por ahora.
Structural and Economic Approach to the Selection of Peak Regulating Capacities at Thermal Power Plants
Authors: Bohdan E. V. , Karnitski M. B.
Published: December 2023

The output of power unit No 2 of the Belarusian NPP to the level of neutron power development of 100 % of the nominal level has changed the structure of generation of the Unified Energy System (UES) of Belarus. At the current loads of the inter-heating period of 2023, the share of a nuclear power plant with two power units operating at full capacity in the daily generation structure of the Republic is about 50 %. In order to balance the UES of Belarus during the operation of two power units of a nuclear power plant at night, the application of adjustment regulatory measures that exceed the available capabilities is required. The almost complete use of the adjusting range of the CHP will forcibly cause, on a larger scale, to the shutdown of the blocks during the load failures at night, followed by the start-up from the non-cooled and hot statuses. These operating modes of generating equipment are inevitable in the current conditions of the electricity market, which has led to the emergence of most complex tasks to assess the economic and technical efficiency of involving or another equipment of power plants in such modes. The paper proposes an approach to solving the problem of achieving an effective combination of reliability and efficiency of energy systems on the example of gas turbines and CCGT power units. A generalized desirability function has been obtained, which includes a number of parameters for choosing a rational relationship and mutual influence between the reliability and efficiency of electricity production with the participation of thermal power plant equipment in regulating the daily load schedule. The proposed mathematical model is an effective means of analyzing the suitability of equipment for use in the required operating modes.
Impact of Renewable Energy Sources on the Electricity Generation Cost

Published: December 2023

The study involves scenario modeling based on the construction of energy chains that determine the flow of energy from the extraction and import of energy resources through technologies for transforming energy forms, transmission and distribution to the final consumer. A fundamental model of the energy system of the Republic of Belarus was also built. The principle of minimizing total system costs is chosen as the objective function for modeling, provided that a number of restrictions imposed on the power system are met. For the purpose of energy system balancing, it was proposed to use the potential of hydropower, viz. existing hydroelectric power plants for scenario 1 and technically possible potential for scenario 2. As a result of the modeling, the structure of electricity production was obtained according to two scenarios. Based on the resulting structure, the cost of producing electrical energy was determined. Two approaches were considered: approach 1 that took into account the cost of electricity production at nuclear power plants which can be classified as new, and approach 2 that took into account the cost of electricity production at nuclear power plants, which can be attributed to the existing generation. The production cost of electricity by 2030 is predicted. When approach 1 is used its level is of 63.3 US dollars/(MW·h) under scenario 2 versus 65.3 US dollars/(MW·h) under scenario 1; when approach 2 is used, its level is of 37.5 US dollars/(MW·h) versus 39.4 US dollars/(MW·h), respectively. Also, the economically feasible potential for using solar energy was determined, which by 2025 will amount to 0.91–1.45 billion kW·h/year, and by 2030 – 2.15–3.46 billion kWh/year; the same for wind energy is 1.55–2.39 billion kW·h/year and 3.69–5.67 billion kWh/year, respectively; the same for hydropower is 1.11–1.45 billion kW·h/year throughout the entire period under review until 2030. Based on the study, it became possible to find out that in the Republic of Belarus it is economically feasible and technically possible to replace up to 20.0 % of electrical energy generation by 2030 with energy produced from renewable energy sources.
