Some properties of thermal insulating cement mortar using Ponza aggregate
Authors: Fattah Rania Amer , Al-Shathr Basil S. , Abed Suhair K.
Published: October 2023

Lightweight aggregate (LWA) mortar is made using lightweight or low-density aggregate, which improves properties such as thermal insulation, durability for freezing and thawing, fire and temperature resistance, and sound insulation. This research aims to use lightweight fine aggregate obtained from crushing natural rocks that are locally called “Ponza” to produce LWA mortar with different mix proportions to study the possibility of using it to produce blocks that can be erected on the outer side of the walls of old buildings to provide good thermal insulation. It also presents a study about the internal curing property of the produced cement mortar, which comes from the absorbed water by the used surface-saturated dry Ponza aggregate. The process includes using three mix proportions (1:1, 1:0.7, and 1:0.5) by weight of cement: fine aggregate. The samples were cured by dividing them into five groups, including moist curing for 1, 3, 7, and 28 days and the fifth group was moist cured for 1 day and then covered by a thin layer of flan coat. Dry density, compressive strength, flexural strength, and thermal conductivity for ages (7, 28, and 56 days) have been tested. The findings indicate that it is possible to produce thermal insulating lightweight cement mortar with mixtures of 1:0.7 or 1:0.5 cement to LWA, using Ponza aggregate, since the results showed an acceptable range of compressive and flexural strengths reaching about 14.75 and 2.91 MPa, respectively, a bulk density of less than 1,600 kg/mm3, and a lower thermal conductivity than many building materials.

Published: October 2023

The present study employed molted feather ash extract from Pavo cristatus to synthesize zinc oxide nanoparticles (Pcf-ZnONPs). The Pcf-ZnONPs were characterized through advanced spectroscopy techniques to study the chemical and physical properties of NPs. Pcf-ZnONPs specifically exhibit an absorption peak at 365 nm in the UV spectroscopy analysis. TEM and SEM confirmed the nanoscale presence of ZnO. The antibiofilm and antibacterial properties of Pcf-ZnONPs were assessed against Staphylococcus aureus and Pseudomonas aeruginosa. At a concentration of 25 µg·mL−1, Pcf-ZnONPs exhibited a significant reduction in the thickness of bacterial biofilms. Breast cancer cell lines (MDA-MB-231) and fish cell lines were used to investigate in vitro anticancer activity. The MTT experiment demonstrated that Pcf-ZnONPs have good anticancer efficacy against a breast cancer and a fish cell line. The nontoxicity and biocompatibility of Pcf-ZnONPs were also investigated, exhibiting excellent hemocompatibility with red blood cells and no appreciable toxicity in Brine shrimp. In conclusion, Pcf-ZnONPs may be deemed nano-biomedicine compatible with biological systems for the treatment of bacterial illnesses in higher species.
A systematic review of the use of virtual reality in teaching Chinese as a foreign language
Authors: Liu Weiming
Published: October 2023

The purpose of this review is to provide a thorough analysis of existing research on the implementation of virtual reality (VR) in teaching Chinese as a foreign language (TCFL). In recent years, there has been a growing interest in the potential benefits of VR for language learning, and multiple studies have explored its application in TCFL. However, to date, no systematic reviews on the specific uses of VR in TCFL have been conducted. This study aims to bridge this gap by conducting a comprehensive review of empirical articles on the topic, identified from the Scopus and Web of Science databases. The search terms include “VR”, “virtual reality”, and “Chinese language”. The findings of this review shed light on the current trends in VR-related publications in the field of TCFL, the research settings where VR is used to support learning, and the potential benefits and effectiveness of VR in enhancing Chinese language learning, such as linguistic growth, communication skills, motivation, and immersive and authentic learning contexts. The review also highlights the challenges and limitations of using this technology in TCFL. The significance of this review lies in its potential to inform educators, researchers, and practitioners interested in using VR in TCFL about the current state of research and its implications for language learning. It can also contribute to the development of best practices for the effective use of VR in TCFL, ultimately leading to improved language learning outcomes for students.
CFD modeling of natural convection in pebble bed geometry with finite volume method
Authors: Said Çatalbas Salih , Tiftikci Ali
Published: October 2023

In this study, we used the finite volume method to computationally model natural convective flow in packed bed geometry. Using the OpenFOAM® v2112 code, we performed the computational analysis. We successfully meshed the intricate packed bed flow geometry, which consists of several spheres positioned at random. The spheres have sizes of 0.006 and 0.01 m, and the associated Rayleigh numbers are 1.83 × 107 and 8.48 × 107 respectively. We used the packed bed heights of H/d = 5, 10, and 20 in the simulations. By comparing the results of the OpenFOAM® v2112 simulations of the natural convection flow for all self-heating sphere in a packed bed, we demonstrated that the velocity distributions and Nusselt values are in good agreement with the experimental data. Additionally, it was evident from the velocity and temperature distributions in a packed bed core that there was a major temperature rise at nearby low velocity fields and a minor velocity rise in the intermediate and upper elevations. We showed that increasing the height of the pebble-bed core and correspondingly increasing the quantity of spheres inside it makes the flow more difficult and also generates local hot spots. This study is notable for using the finite volume method to evaluate natural convection flow in all self-heating packed beds and for simulating packed bed flow using a significant number of spheres. These two factors contribute to the originality of this work.

Published: October 2023

Chronic obstructive pulmonary disease (COPD) is commonly caused by smoking. FUN14 domain-containing protein 1 (FUNDC1) plays a fundamental role in mitochondrial autophagy and apoptosis in cigarette smoke extract (CSE)-treated BEAS-2B cells. The present study investigated the mechanism of action of FUNDC1 in mitochondrial dysfunction and apoptosis in CSE-treated BEAS-2B cells. The interaction between ubiquitin-specific peptidase 19 (USP19) and FUNDC1 was analyzed using co-immunoprecipitation. Effects of USP19 knockdown and/or FUNDC1 overexpression on the survival, apoptosis, mitochondrial membrane potential, and oxygen consumption rate (OCR) of BEAS-2B cells treated with 15% CSE were determined. In BEAS-2B cells, CSE inhibited cell survival, promoted apoptosis, increased the expression of USP19 and FUNDC1, increased the ratio of LC3 II to LC3 I (LC3 II/I), and decreased mitochondrial membrane potential and TOM20 levels. In CSE-treated BEAS-2B cells, USP19 knockdown reduced FUNDC1 and LC3 II/I, increased the levels of TOM20, improved cell survival, mitochondrial membrane potential, and OCR, and inhibited apoptosis. USP19 deubiquitinates FUNDC1. FUNDC1 overexpression inhibited the effect of USP19 knockdown in CSE-treated BEAS-2B cells. Overall, decreasing USP19 expression alleviates CSE-induced mitochondrial dysfunction in BEAS-2B cells by downregulating FUNDC1, providing novel insights into the molecular mechanism of FUNDC1 regulation in COPD.
Das Überflüssige und die Überflüssigen
Authors: Dederich Markus , Zirfas Jörg
Published: October 2023

Diese Einleitung skizziert neben einigen begrifflichen Vorbemerkungen zwei Themenfelder, nämlich den Müll und eine Gruppe von Menschen, die in der Soziologie „die Überflüssigen“ genannt werden. Einerseits wird deutlich, dass der Müll die Rückseite der materiellen Kultur in ihrer Vielfältigkeit darstellt und dass die Geschichte der materiellen Kultur immer auch eine Geschichte dessen ist, was Menschen hinter sich lassen, wessen sie sich entledigen und was sie entsorgen. Andererseits macht die soziologische Ungleichheitsforschung deutlich, dass die „Überflüssigkeit“ von Menschen in einen Zusammenhang mit dem Problem der sozialen Exklusion und damit mit gezielter Ausgrenzung und funktionaler Ausschließung gebracht werden kann.
Überfluss und Überdruss in der Musik
Authors: Roch Eckhard
Published: October 2023

Musik ist eine Kunst des Maßes. Tonhöhe, Tondauer, Takt und Metrum, ferner Tempo und Lautstärke sind die messbaren musikalischen Parameter, die über- oder unterschritten werden können. Die Kategorie des Überflusses generiert in der Musik daher eine Reihe von Oppositionen wie: zu hoch/zu tief (Tonhöhe), zu laut/zu leise (Dynamik) usw. Ein dynamisches Ungleichgewicht entsteht, das zu Zwecken des musikalischen Ausdrucks nutzbar gemacht werden kann. Das Streben nach dynamischer Steigerung durch Überfluss ist ein typisches Merkmal romantischer Musik. Systemtheoretisch betrachtet bilden Produktion und Rezeption von Musik homöostatische Systeme aus, die durch Überfluss und/oder Mangel (Beschränkung) geregelt werden.

„Zu viel! Zu viel! O, daß ich nun erwachte!“

Richard Wagner, Tannhäuser, 1. Akt, 2. Szene.

Der Ausruf des Minnesängers Tannhäuser aus Richard Wagners gleichnamiger Oper könnte als ein Motto für Überfluss und Überdruss in der Musik des 19. und 20. Jahrhunderts bis hin zu unserer Gegenwart gelten. Zwar ist Überfluss keine musikalische Kategorie, aber die Phänomene des „Zu viel!“ oder des „Zu wenig!“ lassen sich bei ihr sehr wohl beobachten.
Diego Rivera
Authors: Castellano González Cristina Isabel
Published: October 2023

The representation of short-haired women, also called pelonas, in the work of Diego Rivera is a subject that has not been studied much when compared to the numerous critical studies of the murals where they represent the mythical bodies of indigenous women. The objective of this article is to study the representation of women who appear in a panel that was created in the Ministry of Public Education in 1925, which is part of the Visión política del pueblo mexicano series and is located in El Patio de las Fiestas. This study develops a formal and aesthetic analysis of the work that is based on gender-study approaches to muralism and the analysis of chronicles and historical events of the time.
Cartographies of Contemporary Class Struggles
Authors: Ponce de León Jennifer S.
Published: October 2023

This essay provides an interdisciplinary analysis of the work of the Iconoclasistas, a Buenos Aires-based duo whose practice combines graphic art, counter-cartography, radical pedagogy, and militant research. The Iconoclasistas’ heterodox landscape illustrations and collectively produced maps demonstrate how various territorial conflicts in South America express class struggles that operate at multiple geographic scales. In so doing, they show how apparently local conflicts express dynamics of transnational capitalist accumulation, including its neocolonial character, while also revealing material relations between seemingly disparate popular struggles. This essay focuses on the Iconoclasistas’ early work representing urban life in Argentina from 2007, as well as on works addressing the deleterious effects of extractivism (or neoextractivism) created between 2007 and 2019. I argue that these works contribute to the insights of ecological Marxism by showing how contemporary processes of capitalist accumulation plunder nature and shape social and natural environments in ways that degrade the living conditions of people of the working and popular classes, as well as those of other species. The Iconoclasistas’ collective mapping workshops utilize techniques of Marxist pedagogy, while bringing attention to visual ideologies and ways spatial relations shape consciousness. This essay shows how this practice was influenced by the politics and organizational forms of recent social movements, and how it contributes to their production of knowledge. It also situates the Iconoclasistas’ work within a tradition of Marxist cultural praxis that values formal experimentation and that concerns itself with reworking the social relations of cultural production, distribution, and reception.
THE EFFECTS OF APPLYING CHITOSAN OF DIFFERENT MOLECULAR WEIGHTS ON THE GROWTH AND QUALITY OF KAMCHATKA BERRIES (LONICERA CAERULEA L.): PART 1
Authors: Ochmian Ireneusz , Krupa-Małkiewicz Marcelina
Published: October 2023

Kamchatka berries contain many valuable organic and mineral compounds. However, the ripe berries are not very firm and have low transport resistance. We aimed to study the effect of chitosan solutions of different molecular weights on the growth, yield, and quality of Kamchatka berries. Chitosan with lower molecular weights, 3 and 12 kDa, stimulated plant growth, while those with molecular weights above 50 kDa reduced plant growth compared with control shrubs. Chitosan 125 and 500 kDa increased Kamchatka berry yield. In addition, chitosan 125 kDa increased fruit weight throughout the yield period. Fruit sprayed with chitosan 3, 5, and 50 kDa were dark in colour at harvest. Chitosan 3, 5, 12, and 50 kDa increased fruit/skin resistance to mechanical damage. Finally, chitosan 3, 5, 50, and 950 kDa increased average fruit firmness. Overall, we recommend higher molecular weight chitosan to increase yield and lower molecular weight chitosan to increase firmness and resistance to damage.

Published: October 2023

We investigated the adsorption of silver(I) from silver nitrate (AgNO3) and silver sulphate (Ag2SO4). We compared the adsorption ability of chitosan in the form of hydrogel beads with that of chitosan acetate – an initial solution from which the beads were derived. We developed a model of adsorption kinetics, assuming the simultaneous occurrence of the diffusion process and the chemical reaction. We confirmed and described the chemical nature of adsorption based on the Fourier-transform infrared and X-ray photoelectron spectra.

Authors: Patjamontri Supitcha , Spiers Alexander , Smith Rachel B , Shen Chen , Adaway Jo , Keevil Brian G , Toledano Mireille B , Faisal Ahmed S
Published: October 2023

Context

Salivary androgens represent non-invasive biomarkers of puberty that may have utility in clinical and population studies.

Objective

To understand normal age-related variation in salivary sex steroids and demonstrate their correlation to pubertal development in young adolescents.

Design, setting and participants

School-based cohort study of 1495 adolescents at two time points for collecting saliva samples approximately 2 years apart.

Outcome measures

The saliva samples were analyzed for five androgens (testosterone, androstenedione (A4), 17-hydroxyprogesterone, 11-ketotestosterone and 11β-hydroxyandrostenedione) using liquid chromatography-mass spectrometry; in addition, salivary dehydroepiandrosterone (DHEA) and oestradiol (OE2) were analysed by ELISA. The pubertal staging was self-reported using the Pubertal Development Scale (PDS).

Results

In 1236 saliva samples from 903 boys aged between 11 and 16 years, salivary androgens except DHEA exhibited an increasing trend with an advancing age (ANOVA, P < 0.001), with salivary testosterone and A4 concentration showing the strongest correlation (r = 0.55, P < 0.001 and r = 0.48, P < 0.001, respectively). In a subgroup analysis of 155 and 63 saliva samples in boys and girls, respectively, morning salivary testosterone concentrations showed the highest correlation with composite PDS scores and voice-breaking category from PDS self-report in boys (r = 0.75, r = 0.67, respectively). In girls, salivary DHEA and OE2 had negligible correlations with age or composite PDS scores.

Conclusion

In boys aged 11–16 years, an increase in salivary testosterone and A4 is associated with self-reported pubertal progress and represents valid non-invasive biomarkers of puberty in boys.
In-silico study of the Effectiveness of Allium sativum L. extract as an Angiotensin-Converting Enzyme (ACE) Inhibitor in Hypertension
Authors: Limanto Agus , Husain Elma Eka Fitra , Dewajanti Anna Maria
Published: October 2023

Over the last decade, the global prevalence of hypertension rate has increased by 5.2% and, in Indonesia, the prevalence rate has increased significantly from 25.8% in 2013 to 34.1% in 2018. Hypertension treatments using blood pressure-lowering drugs, such as angiotensin-converting enzyme (ACE) inhibitors, often cause unpleasant side effects. These side effects increase the interest in using potentially effective natural remedies, such as garlic. This study aimed to determine which organosulfur compounds in garlic can act as an ACE inhibitor to reduce blood pressure in hypertension using a cheminformatics approach. Eighteen organosulfur compounds of Allium sativum L. were screened based on Lipinski’s rules and ADMET evaluation. Seven compounds passed the screening and were subjected to QSAR analysis, molecular docking analysis, and molecular dynamics simulations to assess the stability of the protein. The seven compounds then underwent molecular docking and QSAR analysis. Ajoene (4,5,9-trithiadodeca-1,6,11-triene-9-oxide) and S-allylmercaptocysteine (SAMC) were two compounds with better docking values compared to the positive control compound. The QSAR analysis also showed that SAMC had an activity as an ACE inhibitor. The ADMET evaluation showed that Ajoene and SAMC had good absorption and could not penetrate the blood-brain barrier. Molecular dynamics simulation of ACE complexes Ajoene, SAMC, and Captopril ranged from 0.05 to 5.61 Å but exhibited a pattern of synonymous fluctuations for most residues. Based on the simulation data, the organosulfur compounds from garlic, Ajoene, and SAMC are proven to have a mechanism of action as ACE inhibitors to reduce blood pressure in hypertension.
Ethnic Mobility and the Formation of Political Identity in Indonesia
Authors: Setiawan Refly , Sergeev Sergey A.
Published: October 2023

Indonesia is an archipelagic country that has many tribes and cultures, which make Indonesia a multi-cultural country. There are 5 religions recognized in Indonesia based on the Law of the Republic of Indonesia, namely: Islam, Christianity, Hinduism, Buddhism, and Confucianism. This research is related to ethnic mobility and the formation of political identity in Indonesia which is currently very interesting to be discussed by various researchers around the world, not only in Indonesia. In this study, researcher discuss ethnic mobility and the formation of political identity based on history that has occurred in Indonesia to date. The Indonesian nation Indonesia adheres to the Pancasila ideology so that the national ideology has a major influence on the unity and integrity of the nation. In this study, researcher also examined the ideological values of Pancasila and the nation's unifying motto called Bhinneka Tunggal Ika. This study uses a qualitative descriptive approach in which the researcher conducts a descriptive elaboration of ethnic mobility and the formation of political identity in Indonesia and ethnic participation in political parties in Indonesia. The results of the study show that in the past there were still many Indonesian people who considered themselves local residents and were reluctant to accept other ethnic groups to occupy certain positions in an area, including political positions. The separatist movement that emerged in an area due to the inequality of one region with another, such as the islands of Java and Sumatra, had caused inter-ethnic conflict and many people were anti-Chinese in the 90s. However, currently, Indonesia has provided space for various tribes and religions to be involved in political development in Indonesia based on Pancasila and the 1945 Constitution. Indonesia as a multiethnic country has upheld democratic freedoms for all nations and provided regional autonomy policies for each region in order to improve public welfare.
Maladministration in Indonesia's Interreligious Marriage
Authors: Hidayat Asep Syarifuddin
Published: October 2023

In Indonesia, the polemic on interfaith marriages has not yet ended, even though over time and the times. Even though the issue of interreligious Marriage has been handled and regulated in the Marriage Law, there are still many people who practice it. In Indonesia, interfaith marriages cause not only legal problems but also administrative ones. There are still exceptions to the Marriage Act that allow couples to marry across religions. Because according to positive Indonesian Law, Marriage is not equated with a simple genetic relationship. However, the administration must prove a legal relationship with the state, including the registration of marriages. The research method used is a qualitative research method with a literature approach. The results of the study state that there are still gaps and opportunities for maladministration in interfaith marriages. The behavior occurs in the form of apostasy or changing religions before Marriage, then changing beliefs after Marriage. This was done to get the legality of Marriage in the form of a marriage book. These maladministration opportunities must be closed and eliminated by making government regulations or giving strict sanctions to the perpetrators of maladministration. The sanctions are criminal or fines for people who carry out legal smuggling like this.
Deus da “transcendência desviada"
Authors: Conde da Silva Alessandra F. , Machado dos Santos Thiago Gabriel
Published: October 2023

Desde a sua publicação, em 1959, a Crônica da casa assassinada (2008), de Lúcio Cardoso, configura-se como a obra mais estudada do romancista. Muitos  foram os críticos literários que demarcaram a importância desse romance na obra de Cardoso, tais como Álvaro Lins (1963), Alfredo Bosi (2015), Temístocles Linhares (1971), Massaud Moisés (2019) e Manuel Bandeira (1960). Além deles, Wilson Martins (1959) e André Seffrin (2008), em críticas realizadas sobre o romance, expõem o recuo dramático a que são sujeitas as personagens femininas centrais, Ana e Nina, no último capítulo da obra. No “Pós-escrito numa carta de Padre Justino”, o capítulo que arremata os acontecimentos na chácara dos Meneses, Ana confessa que André, reconhecido inicialmente como filho de Nina, é, na verdade, seu filho. Os críticos em questão compreendem o recurso dramático de Lúcio Cardoso, no capítulo final do romance, como um pedido de desculpas por abordar tema tão espinhoso quanto o incesto. Martins (1959) e Seffrin (2008) atribuem, também, lugar ao catolicismo do autor e ao moralismo e convencionalismo a que ele cedeu. Este artigo tem por objetivo, então, observar de que maneira o “Pós-escrito numa carta de Padre Justino”, diferentemente do que apontam os dois críticos, confere unidade à Crônica da casa assassinad quando lido a partir das orientações feitas em Mentira romântica e verdade romanesca (2009), de René Girard. Para tanto, analisa, de modo detido, a trajetória de Ana e Nina ao longo da narrativa e busca compreender, no pós-escrito, como as  explicações obsequiadas na voz de Padre Justino gestam uma atmosfera menos conflitiva e maniqueísta no entendimento mimético dessas duas personagens.

Egyre erőteljesebb igény jelentkezik a nagy alapterületű, belső alátámasztás nélküli térlefedések iránt. A különféle tartószerkezeti megoldások közé tartoznak a tensegrity szerkesztési elven alapuló kábelkupola-rendszerek, melyek a viszonylag egyszerű statikai viselkedésük és anyagtakarékosságuk mellett könnyű szerelhetőségük miatt is kedvező megoldást jelentenek. A kábelek nyomóerővel szembeni ellenállásának hiánya és a nagy elmozdulások okozta anyagi és geometriai nemlinearitás miatt azonban a hagyományos végeselemes eljárások nem alkalmasak a statikai analízis végrehajtására. A dinamikus ellazítás nevű, fokozatosan közelítő iteratív eljárás alkalmas a szerkezeti analízis elvégzésére. Ennél a módszernél elegendő az egyes csomóponti szabadságfokoknak megfelelő mozgásegyenleteket felírni és megoldani, nincs szükség a szerkezet merevségi mátrixának az előállítására. A kutatás célja egy dinamikus ellazításon alapuló numerikus modell létrehozása és kábelkupolák parametrikus vizsgálatának numerikus alapon történő végrehajtása. Az alkalmazott programkörnyezet a Rhinoceros 3D és annak Grasshopper almodulja, mely különösen alkalmas paraméteres vizsgálatokra.

How expected and experienced reward and relief contribute to gaming-related mental imagery and gaming frequency in daily life: Testing a dual pathway hypothesis
Authors: Brandtner Annika , Müller Silke M. , Brand Matthias
Published: October 2023

Background and aims

Research on the development of gaming disorder assumes that the quality of reinforcement learning as well as the content of use expectancies are initially rewarding in the early stages of the addictive behavior and becomes steadily more compensatory in the later stages. This assumed transition could be reflected in gaming-related mental imagery as well as the decision to play videogames in daily life.

Methods

We recruited 127 individuals who play videogames. Following a strict diagnostic procedure, individuals were either classified as showing casual or at-risk gaming patterns. The experience and expectancy of reward and relief were assessed in the laboratory, followed by a 14-day ambulatory assessment asking for gaming-related mental imagery intensity and playing frequency. Besides group differences, we tested a gratification and a compensation pathway in a structural equation model among groups separately.

Results

Results indicate that mental imagery and playing frequency as well as reinforcement processes and use expectancies are heightened among individuals showing at-risk gaming patterns as compared to casual gaming patterns. Gaming-related mental imagery was only predicted by compensation among individuals showing casual gaming patterns, and we found no significant predictions for daily gaming frequency in any of the models.

Discussion and conclusions

The results implicate that individuals with at-risk gaming patterns might hold stronger learned reinforcement contingencies. Daily usage seems unaffected by these contingencies, possibly indicative of habitualized behaviors. Additionally, the results provide some support for the consideration of imaginal desire thoughts as a specific coping mechanism in the context of gaming behaviors.

Among the criminal problem that are faced by society today is children crimes and violations, which legally referred to as "child crime". Consequently, they must be held accountable through a judicial process that can lead to imprisonment. In Indonesia, one of the places for child incarceration is in the Children's Correction Center (LPA) of Blitar. The study aims to determine the implementation of imprisonment policy for children in LPA Blitar and the Islamic criminal law's perspective. The results of this study concluded that the criminal justice process for children criminals in LPA Blitar prevails under the current law. As for the efforts of the Blitar LPA in its implementation of the policy is to provide guidance and education in a best and fair manner tailored with the evolution of children's psychology. In Islamic law, there is no prohibition about children's punishment as long as the child has passed the age of baligh, but must prioritize the education and mental development of the child. It is in line with sharia law and relevant law in Indonesia

A country has the highest legal norms called the Constitution. Undang-undang Dasar Negara Republik Indonesia Tahun 1945 is a written constitution in Indonesia. The Constitution can be used as an absolute grip in the survival of the society, the nation and the state as it is considered as the political picture. A legal force is demonstrated by the existence of a constitution, therefore it must be obeyed and upheld without the slightest deviation. Through a theoretical approach, this paper discusses the history of the development of Indonesian state administration, mostly about the constitution that was once in force. The author concludes that based on the Indonesian Constitutional history there have been several stages of change in the period of 1945 until now. The New Order's political practices caused trauma to the Indonesian people in the existing constitutional, with the idea coming up to amend the Constitution. Changes to the stages of the Constitution in Indonesia include UUD 1945, UUD RIS, UUDS 1950 and back to UUD 1945 with amendments 4 times and is valid until today. Each of these constitutional stages has a unique constitutional model. After UUD 1945 was amended it was clear that democratic life was growing better. Not only that, the progress in the constitutional system is also getting bigger, especially with the existence of a check and balance format.
Revocation of The Attachment III of The Presidential Regulation Number 10 of 2021 in The Perspective of Human Rights and Maqasid Al-Shari‘ah
Authors: Sanuri Sanuri
Published: October 2023

This research is based on a decision of the President of the Republic of Indonesia, Joko Widodo, by revoking the Attachment III of the Presidential Regulation Number 10 of 2021 concerning the business sector of investment in the liquor and alcoholic drink industry. This presidential decree attracts a wide attention from all levels of Indonesian society. Most of them welcome the decision, and a few are more optimistic about the implementation of the presidential regulation because it has actually offered a clear and proportional regulation. To get a sharp analysis result, the researcher looks at this constitutional fact through the theory of human rights and maqasid al-shari’ah. Based on the research results, it is stated that the decision of the President of the Republic of Indonesia by abolishing the presidential regulation is in line with the basic values ​​and principles contained in human rights and maqasid al-shari’ah. Even so, there are some basic rights points that need serious attention from the government, particularly how to revive the people’s economy which is teetering due to the Covid-19 pandemic. At least, this is the reason for arguing for groups who are oppossing to the presidential decision.

Sebagian besar dari mereka menyambut gembira keputusan itu, dan sebagian kecil lebih optimis dengan pemberlakuan peraturan presiden itu karena sebenarnya telah menawarkan suatu regulasi yang jelas dan proporsional. Untuk mendapatkan hasil analisis yang tajam, peneliti melihat fakta konstitusi ini melalui teori Hak Asasi Manusia dan maqasid al-shari’ah. Berdasarkan hasil penelitian menyatakan bahwa keputusan yang diambil Presiden Republik Indonesia dengan menghapus peraturan presiden itu sejalan dengan nilai-nilai dan prinsip-prinsip dasar yang tertuang dalam hak asasi manusia dan maqasid al-shari’ah. Meskipun demikian, ada beberapa poin hak-hak dasar yang perlu mendapatkan perhatian serius dari pemerintah terutama bagaimana membangkitkan perekonomian rakyat yang tertatih-tatih akibat pandemic Covid-19. Setidaknya, inilah yang menjadi alasan mendasar kelompok yang berseberangan dengan keputusan presiden tersebut.
Relevance of Ijtihad Ibn Taimiyah to Contemporary Jurisprudence
Authors: Achmad Fageh
Published: October 2023

The ijtihad Ibn Taimiyyah update was built in two models of ijtihad;  istidlal and istinbat. Relevance strengthening of the naqly istinbat evidence and the approach of rationality independence (istidlal) is urgently needed. Although in reality, Ibn Taimiyyah was more likely to wear the istinbat model than istidlal.  Ibn Taimiyyah said the foundation of the ijtihad method comprehensively, the naqly and ‘aqly evidence applied simultaneously in every determination of Islamic law. Upon consideration of every sharia law, there must be a good content of shari'a purposes, then ibn Taimiyyah's most popular view is that valid shariah evidence must correlate with the correct rational evidence. Ibn Taymiyah's legal method uses: (1) the Qur'an, (2) sunnah,  (3)  ijmâ', (4)  qiyas, (5)  istish}ab, and (6)  maslah}ah al-mursalah. There is a strong relevance between the renewal of ijtihad Ibn Taimiyyah and the development of Islamic law, especially in the field of contemporary jurisprudence with the approach of mas}lah}ah. Such as the ability to exchange and sell waqf property, the ability to appoint leaders from non-Muslims, the ability to buy and sell goods embedded in the ground, and the ability to buy and sell goods on credit.
 
Abstrak: Pembaruan ijtihad Ibn Taimiyyah dibangun dalam dua model ijtihad; istidlal dan istinbat. Penguatan relevansi pembuktian naqly istinbat dan pendekatan independensi rasionalitas (istidlal) sangat dibutuhkan. Meski pada kenyataannya, Ibnu Taimiyyah lebih cenderung memakai model istinbat daripada istidlal. Ibnu Taimiyyah mengatakan landasan metode ijtihad secara komprehensif, dalil naqly dan 'aqlī diterapkan secara simultan dalam setiap penetapan hukum Islam. Berdasarkan pertimbangan setiap hukum syariah, harus ada isi yang baik dari tujuan syariah, maka pandangan paling populer ibn Taimiyyah adalah bahwa bukti syariah yang valid harus berkorelasi dengan bukti rasional yang benar. Metode hukum Ibnu Taimiyah menggunakan: (1) Al-Qur'an, (2) sunnah, (3) ijma', (4) qiyas, (5) istishab, dan (6) maslahah al-mursalah. Terdapat relevansi yang kuat antara pembaruan ijtihad Ibnu Taimiyyah dengan perkembangan hukum Islam, khususnya dalam bidang fikih kontemporer dengan pendekatan maṣlaḥaḥ. Seperti kemampuan menukar dan menjual harta wakaf, kemampuan mengangkat pemimpin dari non muslim, kemampuan jual beli barang yang disematkan di tanah, dan kemampuan jual beli barang secara kredit.

Illegitimate children are not children born from legal marriages based on Islamic law and not registered according to the Marriage Law of Indonesia, but children born from a relationship between a man and a woman without any matrimony ties. According to the majority opinion of ulama fiqh, the child is bequeathed to his father if the child is born after six months of the marriage. The child is bequeathed to his mother only if the child is born before six months. In Jatilangkung, a forced marriage will occur when a woman becomes pregnant out of wedlock, namely marrying a pregnant woman to a man who has impregnated her. According to local tradition, the child's standing is considered the same as a legitimate child resulting from a legal sexual relation; the parents will be responsible for the child, and the child will receive a share of their parent's inheritance. Administratively, the child linage is on the mother's husband, but they should employ a magistered guardian in the marriage.
Abstrak: Anak yang lahir dari perkawinan yang sah menurut hukum Islam dan tidak tercatat menurut Undang-Undang Perkawinan, tidak masuk dalam  kategori anak lahir di luar nikah. Sebab anak yang lahir diluar nikah adalah anak yang lahir dari hubungan antara pria dengan wanita tanpa ada ikatan perkawinan. Menurut pendapat mayoritas ulama dalam hukum Islam jika anak itu lahir setelah enam bulan dari perkawinan ibu dan bapaknya, maka anak itu dinasabkan kepada bapaknya, jika anak itu dilahirkan sebelum enam bulan, anak itu dinasabkan kepada ibunya saja. Pada umumnya di Jatilangkung, ketika ada seorang perempuan yang hamil di luar nikah maka akan terjadi kawin paksa, yaitu mengawinkan perempuan yang hamil dengan laki-laki yang telah menghamilinya. Kedudukan anak tersebut menurut hukum setempat dianggap sama seperti halnya anak sah hasil dari hubungan setelah perkawinan, orang tua akan bertanggung jawab atas anak tersebut serta akan mendapat jatah dari harta peninggalan orang tuanya. Nasabnya secara administrasi akan diikutkan kepada suami ibunya, namun ketika nikah menggunakan wali hakim.
Problem Yuridis Penyelesaian Perkara HAM Berat dalam Sistem Pidana Indonesia dan Pidana Islam
Authors: Ali Mohammad , Rauf Moh. Abd.
Published: October 2023

The expound of human rights cases in Indonesia can not become a problem solver since the enactment of the Human Rights Law in 1999 and the law on the Human Rights Court in 2000. Juridical constraints are the most striking factor in the weak resolution of severe human rights cases, especially in proving and resolving severe human rights cases in the criminal procedural law system. The result of the discussion is that the procedural law for the settlement of human rights cases (Law No. 26 of 2000) still does not accommodate the needs of law enforcement, especially in the investigation process. National Commission on Human Rights (Komnas HAM)'s authority tends to be politically intervened. So that, in the future, it is necessary to adjust the law enforcement system with the rules that have been applied. Whereas as a country with an Islamic majority, although it does not base its laws on Islamic Law; at least the values ​​of Islamic criminal law can be realized from every law enforcement carried out, especially in upholding human rights, which in Islamic Law become the leading benchmark in seeing and enforcing a law.
Abstrak: Penanganan kasus HAM di Indonesia masih dapat dikatakan belum mampu menjadi problem solver sejak diundangkan UU HAM pada tahun 1999 dan UU Pengadilan HAM pada tahun 2000. Kendala yuridis menjadi faktor paling mencolok terhadap lemahnya penyelesaian kasus HAM berat. Terutama pada konteks pembuktian dan penyelesaian perkara HAM berat dalam sistem hukum acara pidana. Hasil dari pembahasan bahwa dalam hukum acara penyelesaian kasus HAM (UU No 26 Tahun 2000) masih belum mengakomodir kebutuhan penegak hukum terutama dalam proses penyidikan. Kewenangan Komnas HAM yang condong selalu diintervensi secara politis. Sehingga ke depan perlu penyesuaian dalam sistem penegakan hukum dengan aturan yang sudah diterapkan. Padahal sebagai negara dengan mayoritas Islam, meski tidak mendasarkan hukum terhadap hukum islam; paling tidak nilai-nilai dari hukum pidana islam dapat diwujudkan dari setiap penegakan hukum yang dilakukan, terutama dalam menegakkan hak-hak asasi manusia yang dalam hukum islam menjadi tolok ukur utama dalam melihat dan menegakkan suatu hukum.
