Kopi merupakan salah satu komoditas pertanian penting di Indonesia. Perkebunan kopi di Indonesia telah menjadi bagian integral dari ekonomi negara dan sumber pendapatan bagi petani di berbagai daerah. Salah satu daerah penghasil kopi di Indonesia yaitu Kab.Enrekang Provinsi Sulawesi selatan. Kopi yang terdapat di Kab. Enrekang yaitu kopi arabika, merupakan salah satu produk unggulan yang perlu dikembangkan dan menjadi tumpuan masyarakat sekitar untuk meningkatkan perekonomian. Pengolahan kopi pasca panen adalah serangkaian proses yang terjadi setelah buah kopi dipanen. Tujuannya adalah untuk mengolah buah kopi menjadi biji kopi yang siap untuk roasting. Roasting adalah proses memanggang biji kopi untuk mematangkan biji kopi, mengembangkan rasa, aroma, dan warnanya. Berdasarkan suhu rosting (penyangraian) dibedakan menjadi 4 yaitu: Suhu Pra-Panggang (Preheat), Panggang Ringan (ligh roast), Panggang Sedang (Medium Roast), dan Panggang Gelap (Dark Roast). Dalam sebuah mesin rosting pemanasan adalah komponen kunci dalam proses roasting kopi. Bent heaters type U adalah jenis elemen pemanas yang dapat digunakan dalam mesin roasting kopi. beberapa keuntungan penggunaan Bent heaters type U dalam penelitian ini, seperti: Bent heaters type U dapat menghasilkan panas dengan cepat dan efisien, dapat mencapai suhu yang diperlukan dengan cepat, memungkinkan proses roasting berlangsung secara efisien, selain itu desain Bent heaters type U memungkinkan distribusi panas yang merata di sekitar elemen. Untuk memperoleh hasil yang efisien digunakan sebuah mikro kontroler yang dihubungkan dengan sebuah thermostat, blower dan layer monitor untuk mengetahui level suhu yang digunakan dalam proses pemanasan. Pada pengujian waktu dan penurunan massa kopi yang diasumsikan sebagai penurunan kadar air digunakan sebagai parameter, sedangkan waktu 8 menit, 10 menit dan 15 menit digunakan sebagai waktu pengujian untuk suhu pengujian terdiri atas 180, 210 dan 230 sesuai suhu kisaran untuk proses rosting. Dari hasil pengujian yang dilakukan diperoleh laju aliran panas rata dihasilkan berkisar 2 °C /min, sedangkan tingkat penurunan massa yang diasumsikan sebagai penurunan kadar ari terendah diperoleh 208,8 gram pada suhu 180 , 8 menit dan tertinggi diperoleh 696,6 gram pada suhu 230, 15 menit.
A wave-resolving two-dimensional vertical Lagrangian approach to model microplastic transport in nearshore waters based on TrackMPD 3.0
Authors: Jalón-Rojas Isabel , Sous Damien , Marieu Vincent 
Published: January 2025

Abstract. Potentially acting as a source or a sink for plastic pollution to the open ocean, nearshore waters remain a challenging context for predicting the transport and deposition of plastic debris. In this study, we present an advanced modeling approach based on the SWASH wave model and the TrackMPD (v3.0) particle transport model to investigate the transport dynamics of floating and sinking microplastics in wave-dominated environments. This approach introduces novel features such as coupling with advanced turbulence models, simulating resuspension and bedload processes, implementing advanced settling and rising velocity formulations, and enabling parallel computation. The wave laboratory experiments conducted by Forsberg et al. (2020) were simulated to validate the model's ability to reproduce the transport of diverse microplastics (varying in density, shape, and size) along a comprehensive beach profile, capturing the whole water column. Our results underscore the robustness of the proposed model, showing good agreement with experimental data. High-density microplastics moved onshore near the bed, accumulating in proximity to the wave-breaking zone, while the distribution of low-density particles varied along the coastal profile depending on the particle properties. The study also sheds light on the primary mechanisms driving microplastic transport, such as Stokes drift, wave asymmetry, and settling/rising velocities. Sensitivity analyses on calibration parameters further confirm the robustness of the model results and the influence of these factors on transport patterns. This research establishes the SWASH–TrackMPD approach as a valuable tool, opening avenues for future studies to contextualize laboratory findings within the complexities of real-world nearshore environments and further refine our comprehension of microplastic dynamics across different beaches and wave-climate conditions.
Dynamic displacement measurement of a wind turbine tower using accelerometers: tilt error compensation and validation

Published: January 2025

Abstract. For vibration-based structural health monitoring (SHM) of wind turbine support structures, accelerometers are often used. Besides the structural acceleration, the measured quantity also contains the acceleration component due to gravity, which is known as tilt error. This tilt error must be quantified and taken into account; otherwise it can lead to incorrect evaluations, especially in the fatigue estimation or the dynamic displacement estimation using accelerometers. The standard solution is to explicitly measure the tilt angle, which requires an additional sensor for each measurement point and is not applicable for already recorded measurements without tilt information. Therefore, a novel tilt error compensation method is presented by using the static bending line. As a result the influence of the tilt error can be estimated in advance, and no additional sensors for tilt measurement are needed. The compensation method is applied to accelerometer measurements of an onshore wind turbine tower and validated with contactless absolute distance measurements from a terrestrial laser scanning (TLS) system. The position and frequency-dependent tilt error of the investigated tower has a significant influence on the quasi-static motion below 0.2 Hz with a minimum amplitude error of 9 %, whereas the normalised bending mode shapes around 0.3 Hz are only slightly affected.

Race, Population Control, and Genocide in Gore Vidal’s Kalki
Authors: Booth Nathanael Thomas 
Published: January 2025

Abstract
Gore Vidal was clearly invested in the problem of population control; in his essays as well as his novels such as Myra Breckinridge (1968) and Kalki (1978), he reflected at length on overpopulation. However, midcentury population discourse was often espoused by Westerners and projected onto the non-Western world. Kalki recognizes the uncomfortable racial subtext that attended midcentury overpopulation discourse. Thus, Kalki shows Vidal grappling with tensions within his own stated beliefs—tensions that are notably absent elsewhere in his body of work. Kalki helps to complicate both Vidal’s own views and the larger issues at work in midcentury population discourse.
Un philosophe du monde ? Retraite et philosophie facile chez Hume
Authors: Haffas Salim 
Published: January 2025

La prosopopée de la Nature à la fin de la première section de l’Enquête sur l’entendement humain arbore sans ambiguïté le rejet de la figure du savant isolé, mélancolique, plongé dans l’incertitude et rejeté par ses pairs. Cependant, Hume lui-même associe l’exigence de la pensée précise à une nécessaire retraite qu’il dû pratiquer pour composer certaines de ses œuvres maîtresses. L’équilibre qu’il prône entre une sociabilité qu’il comprend univoquement comme mondanité et une activité savante exigeante trouve son mode d’exposition privilégiée dans la figure intermédiaire d’une philosophie à la fois facile à comprendre et abstruse dans la qualité de ses raisonnements et dans son objet. Par là, il entend participer au progrès du savoir et à l’instruction de ses semblables, en alliant manière plaisante et matière profonde. La forme de l’essai, qui domine sa production après 1740, est ainsi l’expression, plutôt que d’une stratégie de diffusion de ses écrits, d’un véritable remaniement du projet philosophique humien, qui quitte la pure retraite et la pure spéculation pour exploiter les virtualités pratiques de la pensée sceptique en entrant dans la bonne société.

This article focuses on the famous passage of Lucretius' On the Nature of Things where the poet reenacts in a blazing style Thucydides' description of the plague in Athens. The article lays the emphasis on the change of regime of narration of the disaster from the Greek historian to the Roman poet. The author also attempts to read Lucretius' purple passage in the light of the present pandemic – Covid 19.
Blonde Nihilism. Warhol’s Marilyn
Authors: Mecacci Andrea 
Published: January 2025

The painting cycle Warhol dedicated to Marilyn Monroe in 1962 is not only one of the highest moments of Pop Art, but one of the most complex meditations on the identity of the twentieth-century subject. Focusing exclusively on the dimension of the media mask, Warhol elaborates an aesthetic of artifice in which the “I” can only survive in its mimetic projections: constructability of beauty, affirmation of the universe of photoreproduction, marginalization of nature, virtuality of the subject and its social expendability.
« La patrie des esclaves est le soulèvement »
Authors: Hervé Stéphane 
Published: January 2025

Toussaint Louverture has been called the Black Spartacus, who leaded the only successful slave revolt in History. The question is: Can Spartacus be victorious? This paper aims to think about this contradiction, this impossibility by analyzing plays based on the life of the Haitian hero written by Lamartine, C.L.R. ames and Glissant. How these works deal with the victory problem? I try to bring destituent possibilities out from these texts: marronage and fraternity as bias to preserve subversive virtues beyond the deceptive success.
Rosa Luxemburg, divenire-donna di Spartaco, o su una politica comunista a venire
Authors: Salza Luca 
Published: January 2025

In 73 B.C., the slaves rose up in Rome. This revolt founded a new myth for posterity, the War of the Poor, epitomized by a name: Spartacus. Two thousand years later, Spartacus reappears in Germany. To oppose the war. To determine another course of events. The return of the myth of Spartacus provides a revolutionary becoming for the German communists. The hypothesis of these pages is that, during the meeting with Rosa Luxemburg, Spartacus also experiences several metamorphosis. There is perhaps a becoming-woman of Spartacus. Certainly there are in the pages of Luxemburg leads for another communism to come.
Spartacus. Réécritures contemporaines : de Django Unchained à La Planète des singes
Authors: Lacouture Fabien 
Published: January 2025

In 1960, Stanley Kubrick directed Spartacus, based on a script by Dalton Trumbo and a novel by Arthur Koestler. The movie entrenched the figure of Spartacus as revolutionary slave, fighting against slavery. In this article, we study how the figure of the Thracian slave lives on in at least two contemporary characters: Django from Quentin Tarantino’s eponymous movie and Caesar, the ape leading the uprising in 2011’s movie Rise of the Planet of the Apes.
L’ordre insensé Malevitch
Authors: Violette-Pons Émilie 
Published: January 2025

This article studies the way in which the Suprematist paintings of Kazimir Malevitch inspire a poem to Jacques Dupin in 1975. The sharing of a broken poetics is accompanied by an insurrectional and ethical fraternity focused towards the opening and the renewal of the aesthetic creation. Malevich teaches the poet the virtues of an senseless order in order to offer an art freed from convenience and oppression, while leading him to question the foundations of the poem. Malevich's paintings can be considered much more than a support or an object of study for a poet art critic, but rather as a gift that the poet makes to the poem, and whose fecundity offers ontological, political and ethical revelations.
La petite caillera transspécique (un nom qui porte bonheur)
Authors: Brossat Alain 
Published: January 2025

In this article, the author argues that what makes Pinocchio fascinating in today’s context is the constant process of mutations he is involved in, a process that can be envisioned from many angles – metamorphosis from a species to another, animal-becoming, escape lines, etc. Pinocchio is a troublemaker in family as in society for he is an ill-born child, some sort of a prematurate whose fate is to be acosmic, uncontrollable, recalcitrant. Collodi’s novel constantly swings from road movie to tale of terror and this is what makes it so attractive for the children, readers or listeners and for the adults, storytellers. Any reader or listener can see that its happy ending is nothing but scam and lie so that the the show can go on endless – Pinocchio’s quietening is just a pretence, a lull in anticipation of new misconducts and dissolute behaviors ; for Pinocchio is incorrigible and irredeemable – yesterday’s and today’ riffraff...
Du marionnettiste au capitaliste : variations autour de la fonction éducative de Mangefeu
Authors: Martin-Mercier Sylvie 
Published: January 2025

Chapter 9 of the Adventures of Pinocchio features one of the most ambiguous characters in this novel for young people, the terrible puppetshowman Mangiafoco. Contrary to what his erasure in many adaptations might suggest, this character is one of the richest and most complex characters in the Collodian text. Included since the 1881 version, it is interesting in many ways and helps to structure the link between the realm of men and that of puppets, perhaps anticipating Pinocchio’s future and ultimate metamorphosis. Unlike the circus ringmaster who serves as a repellent in his attempt to brutally educate a Pinocchio turned donkey, Mangiafoco appears to be a fundamental player in the puppet’s education and training process, even before Geppetto and the teacher. In fact, the brief encounter between the puppet and the puppeteer trains Pinocchio in fraternity and mutual aid, in defense through speech and discourse, and serves as an introduction to economics. Numerous adaptations and rewritings of this novel have been proposed, whether it be in the form of films, cartoons, novels or comic strips. If the adaptationsreductions intended for younger children often omit the puppet theatre scene, those intended for older children, or even for an adult reader, transform and reinvest the puppeteer’s character, varying its educational weight and meaning, frequently mixing it with the circus director or the little man of the Land of Toys. This article proposes to analyze the educational function of Mangiafoco in different rewritings, from his being damaged in the 1940 Disney studios’ cartoon where Mangiafoco steals Pinocchio and tries to kidnap him, to his attitude that is alternately cynical, vengeful and helping in Arnaud Boutle and Corinne Denoyelle (2008), to his transformation into a stereotypical capitalist in Winshluss (2008).
«Potenza di non», ossia la politica dell’inoperosità
Authors: Didi-Huberman Georges 
Published: January 2025

If the raising is a power, is it the power of what? How does it manifest? Towards which direction does it develop? Is it by any chance a power to end it all? It is the thought of Giorgio Agamben that «raises» these issues and, paradoxically, it is also the one that must «be raised» to answer these questions. Definitely, it is the one that is needed to be inquired for grasping how the raising can be actually translated as the power of-non, namely the power of non-doing. In order to do that, the contribution goes through the work of Agamben and – at the same time – it goes around the notion of inoperativity shaped by the author, which is bound to the idea of the power of non-doing. In particular, the article outlines the terms in which the ethic of the inoperativity – conveyed by the act of refusing – it already implies a politics of inoperativity. A politics that must be thought of as purely destituent: able therefore to exhibit the emptiness of political power. Taken literally, this ability, however, ends up for being vain, just as it turns out to be when the inoperativity is simply assumed as the opposite of the opera (work) and its ultimate place is contemplative life.
Médée, où est ta victoire ?
Authors: Brossat Alain 
Published: January 2025

This article is about the status of myths in contemporary Western societies, on how myths have withered and degraded into stories and shows; how the sublime monster of the myth has become either a pallid criminal or a feminist heroine, that is a character that belongs to the chronicle of the darkest of current events. Medea has lost her panache – she has become an infamous woman – in reference to Foucault’s “infamous men”.
Médée ou l’expérience de l’étrangeté
Authors: Pignarre Florence 
Published: January 2025

This article aims to interpret the myth of Medea as an experience of strangeness based on a nietzschean understanding of the experience. Indeed, Medea is able to disturb our « pulsional configuration », which means shifting the balance power and overturning the way of organizing our human experience. To achieve this, we propose to follow four artistic interpretations of this myth: Medea in the Pasolini’s and Seneca’s works, the staging of the Cherubini’s opera by Krzysztof Warlikowski, and Medea Stimmen of Christa Wolf.
