Authors: Himawan Aldi , Putra Widhy Hayuhardhika Nugraha , Setiawan Eko
Published: April 2024

The Internet of Things (IoT) plays a crucial role in technology advancements, especially in the agricultural sector, such as hydroponics. Manual monitoring of parameters like nutrient levels, pH, and water levels in plants consumes farmers' time and energy and increases the risk of crop failure. This research aims to evaluate the effectiveness of using IoT RAFT (Remote Automated Farming Technology) system for farmers, particularly hydroponic bok choy farmers, in monitoring and controlling plant nutrient levels and the development process using waterfall as a research methodology. Parameters tested in this research include bok choy height, number of leaves, and bok choy harvest weight. We conducted this research on 14 plants for one harvesting period, then we used linear regression to determine the growth rate by calculating the slope. The results show that the plant height, the number of leaves, and harvest weight using the IoT RAFT system are 0.5897 cm/day, 0.6391 leaves/day, and 216.43 grams, respectively. We also compared the IoT RAFT system with a non-IoT bok choy growing method, and we concluded our IoT RAFT system has a better growth rate compared to the non-IoT bok choy growing method.

Authors: Chandra Rudy , Arifin Prasetyo Tegar
Published: April 2024

Samosir has a wide area and several tourist attractions, making it difficult for visitors to explore the island. Not knowing the route can make the journey less fun and waste time. In general, tourists seek to know the fastest path to a tourist location to save time and money while on vacation. As a result, we require an application that will offer directions to the shortest path. This research aims to develop a web-based application that may display a map of the shortest travel to a tourist site. This website will display a map that marks from the origin point to the destination point. The Branch and Bound algorithm is used to determine the shortest path. The Python libraries OSMnx, Folium, and NetworkX modify paths and show a route map with OpenStreetMap. The error value of the distance between the branch, bound algorithm, and Google Maps is used to get the RMSE accuracy value. The RMSE value is 3.02 and MAPE value is 0.0023 indicating that the application produced already has a good implementation prototype. Furthermore, there is no significant distinction between the appearance of maps implementing OpenStreetMap and Google Maps

Authors: Kurniati Florentina Tatrin , Purnomo Hindriyanto Dwi , Sembiring Irwan , Iriani Ade
Published: April 2024

Object detection in digital images has been implemented in various fields. Object detection faces challenges, one of which is rotation problems, causing objects to become unknown. We need a method that can extract features that do not affect rotation and reliable ensemble-based classification. The proposal uses the GLCM-MD (Gray-Level Co-occurrence Matrix Multi-Degrees) extraction method with classification using K-Nearest Neighbours (K-NN) and Random Forest (RF) learning as well as Voting Ensemble (VE) from two single classifications. The main goal is to overcome the difficulty of detecting objects when the object experiences rotation which results in significant visualization variations. In this research, the GLCM method is used to produce features that are stable against rotation. Furthermore, classification methods such as K-Nearest Neighbours (KNN), Random Forest (RF), and KNN-RF fusion using the Voting ensemble method are evaluated to improve detection accuracy. The experimental results show that the use of multi-degrees and the use of ensemble voting at all degrees can increase the accuracy value, and the highest accuracy for extraction using multi-degrees is 95.95%. Based on test results which show that the use of features of various degrees and the ensemble voting method can increase accuracy for detecting objects experiencing rotation

Published: April 2024

Depression, a prevalent mental condition globally, exerts a substantial influence on various aspects of human cognition, emotions, and behaviour. The alarming increase in deaths attributable to depression over the past few years demonstrates the imperative need to address this problem through prevention and treatment interventions. In the era of thriving social media platforms, which have a significant impact on society and psychological aspects, these platforms have become a means for people to convey their emotions and experiences openly. Reddit stands out among these platforms as a significant place. The main aim of this study is to examine the feasibility of forecasting individuals' mental states by classifying Reddit articles on depression and non-depression. This work aims to employ deep learning algorithms and word embeddings to analyze the textual and semantic settings of narratives to detect symptoms of depression. The study effectively employed a BiLSTM-BiGRU model that applied FastText word embeddings. The BiLSTM-BiGRU model analyzes information bidirectionally, detecting correlations in sequential data. It's suitable for tasks dependent on input order or addressing data uncertainties. The Reddit dataset, featuring text concerning depression, achieved an accuracy score of 97.03% and an F1 score of 97.02%.

Published: April 2024

The current trend of conservation of immovable monuments is – in addition to ongoing maintenance and protection – adaptation. Simply taking care of a monument is not an effective way to keep it in good repair if it is not used. Utility is the primary function of architecture, as buildings are erected for this purpose only. No building can survive without function, especially a centuriesold one. This is because the lack of a user condemns any monument to destruction, which leads to ruin and, ultimately, to demolition. Therefore, proper adaptation to new functions and current technical conditions is necessary. In the process of adaptation, all the heritage values of the object should be brought out and only then should new ones be introduced, taking into account the integrity of the monument and ensuring authenticity. Sacred architecture has special cultural and historical values, both tangible and intangible, i.e. spiritual. Continually discussed adaptations of religious buildings in the case of Judaic religious buildings destroyed and abandoned after World War II proved to be the best way to reclaim synagogues. The Kielce synagogue is one of the early examples of adaptation to another function. The building, destroyed during World War II, was rebuilt in the 1950s in a different form than the original one, for use as an archive. This historic building, however, has been standing useless for more than a decade now, and this fact has a destructive effect on its heritage value, therefore it is necessary to take action as soon as possible. Numerous concepts for this building located in a prestigious area in Kielce can be produced, which will be presented and evaluated in terms of substantive potential of utilizing its value in a new incarnation.

Authors: David Ramos
Published: April 2024

The purpose of this research is to gain an in-depth understanding of the lived experiences, beliefs, values, and norms among Mexican-American mixed-status families, living in the Californian cities of South Los Angeles, South Gate, and Santa Ana. Through a qualitative approach, 5 Mexican-American mixed-status family members were interviewed and given the opportunity to tell their story and share their unique experiences. The qualitative data was then analyzed to search for patterns, in which 3 themes emerged. The main findings from this study revealed that Mexican-American mixed-status families are conscious of their undocumented status, however, they manage to separate their uncertainties of deportation from living ordinary, and productive lives with their children. These findings suggest a high level of resilience, which was facilitated through the heavy utilization of coping resources, which included the ethnic immigrant enclave, companionship or fictive kin, transnational ties, and their children’s language and cultural skills.

Engaging with the Qur’an
Authors: Al-Sharmani Mulki
Published: April 2024

In this article, I examine what selected Muslim women in Finland and Egypt do with the Qur’an in their daily lives. I shed light on their modes of engagement with the Qur’an (spiritual, emotional, intellectual, communal). I analyse how their relationship with the Qur’an is shaped and changes over the course of their life. I pay attention to the interplay between the women’s daily lives and the ways in which they experience, learn from, grapple with, and interpret the text. My overall aim is twofold: to contribute to research-based understanding of the Qur’an as daily religious practice that in many ways involves learning both about God and about the complex circumstances of personal life, and to unpack the layered and shifting meanings of this practice in the context of the women’s lives. My analysis is informed by life-story interviews with six women in Helsinki and Cairo (three in each country).
Europos
Authors: Di Cristina Silvia , Gallerani Valentina
Published: April 2024

The Middle Euphrates Valley has always been a key trade route and cultural melting pot since antiquity. Located on, actually bisected by, the modern border between Turkey and Syria, the site of the ancient Hittite capital city of Karkemish has been the object of archaeological excavations since the late 19th century. In 1911-1914 and 1920, an archaeological expedition by the British Museum uncovered levels of the Bronze and Iron ages, but also gave notice for the existence of a Classical settlement which overlay them, identified with Classical Europos. Their final reports gave only tantalizing bits of material culture dated to the later phases of occupation, especially to the Hellenistic, Roman and Islamic periods. Precisely after one century, in 2011 a Turco-Italian archaeological expedition started the excavations anew on the field, providing much new and firmer evidence on the Classical city as well. The main aim of this volume consists in giving a general and complete presentation of the data collected by the joint project of the Universities of Bologna, Istanbul and Gaziantep, in order to produce a general overview as much complete as possible on Europos after the Seleucid re-foundation of the town, from its beginning in the 3rd century BC till the Late Antique period in the 5th-6th centuries AD.

Die Ameisengrille (Orthoptera: Myrmecophilidae) auf dem Kieler Ort und schwimmende Röhrichtinseln als Möglichkeit für die Ansiedlung von Bodenarthropoden auf Ostseeinseln
Authors: Schmidt Joachim
Published: April 2024

Die Ameisengrille Myrmecophilus acervorum (Panzer, 1799) wurde im Oktober 2023 auf der Ostseeinsel
Kieler Ort in der Wismarbucht in einer Bodenfalle nachgewiesen. Aufgrund der besonderen naturräumlichen
Situation deutet dieser Fund auf eine bereits länger zurückliegende Besiedlung dieses
Küstenabschnitts hin. Dies stützt die Hypothese, dass die extreme Seltenheit der Ameisengrille in
Mecklenburg-Vorpommern vor der Jahrtausendwende Ausdruck ihrer versteckten Lebensweise und
fehlender gezielter Nachsuche war, jedoch kein zwingender Hinweis auf eine seither erfolgte Arealerweiterung
in diesen Raum ist. Wahrscheinlich hat die Art den Kieler Ort über die Halbinsel Wustrow
besiedelt, mit der die heutige Insel bis Anfang der 1990er Jahre verbunden war. Alternativ kann die
Ameisengrille den Kieler Ort auch durch Verdriftung über das Salzhaff erreicht haben. Diese Hypothese
wird durch eine aktuelle Beobachtung unterstützt. Beim Sturmhochwasser am 20./21.11.2023 wurden
bis zu 10 m2 große Röhrichtinseln von gegenüberliegenden Uferbereichen am Salzhaff abgerissen
und nahezu unbeschadet auf dem Kieler Ort abgelegt. Eine solche Transportmöglichkeit dürfte es zahlreichen
Bodenarthropoden ermöglichen, auch scheinbar isolierte Insellagen in der Ostsee zu erreichen.
Translation and Memory from the Cremation Ovens in Poland to Freedom in Greece and the US: The Journey and the Manuscripts of Marcel Nadjary
Authors: Gerber Keilah , Mortoza Marina
Published: April 2024

In a timeframe of 35 years, from 1945 to 1980, some manuscripts left by 5 Jewish members of the Sonderkommando were found buried near the crematories in Auschwitz-Birkenau. These prisoners were forced to do activities directly connected to the genocide, and because of that they were considered as bearers of secrets. Known as The Scrolls of Auschwitz, these manuscripts have been held as sources of high historical-social-psychological value. The narrative found in 1980 was written by a Greek Jew called Marcel Nadjary (1917-1971), the only amongst the authors to survive the Lager. The degradation of the papers demanded a long recovery work that recently produced two books: Μαρσελ Νατζαρή Χειρόγραφα 1944-1947 (2018) and Marcel Nadjari’s Manuscript November 3, 1944 (2020). The work of translation from Greek to Portuguese has allowed us to examine the paths in which a survivor of the Gray Zone builds his memories, in two different moments: at the time of the event, and a posteriori. Therefore, it is possible to identify what is kept and what changes in the subjective assumption of History itself, and in the way the author uses the words to narrate his memories and transmit the secrets he carried. Keywords: Marcel Nadjary, translation, testimony, Auschwitz-Birkenau, Sonderkommando.
Understanding Metaphors: A Study with Portuguese 4-6 Year-old Children
Authors: Couceiro Figueira Ana Paula , Santos Cátia , Ribeiro Celia
Published: April 2024

We present the first metaphor comprehension data from 36 Portuguese children aged 4, 5 and 6, using the TCM Júnior, a metaphor comprehension test for young children, in its European Portuguese version. This is an exploratory descriptive study, with a view to collecting data, contributing to the measurement and standardization of the resource used. TCM Júnior is an adaptation of its corresponding Italian acronym, which is in the process of being validated for the Portuguese population in this age group (4 to 6 years old). We describe the resource used, the TCM Junior, Metaphor Comprehension Test for 4-6 years old and the results obtained with a sample. The instrument used is in the process of gauging, or external validation that is, meeting normative data, although it is already subject to adaptation procedures, as it is an original test in Italian. In this study, 36 participants of both sexes participated. Although still incipient, because there are still few data, with groups by age and sex that are not equitable and significant, the results are promising. We will report on the data obtained and analyzed. Although still preliminary and exploratory, with a sample that is still not very representative and significant, the results appear to be not very distant from the averages obtained by their Italian counterparts.

We present the results of a study with a group of children aged 9-14 years old, on the understanding of metaphors. We describe the resource used, the TCM, Metaphor Comprehension Test for children aged 9-14 years and the results obtained with a sample. In this study, 95 subjects of both sexes participated, aged between 9 (4th grade) and 15 (9th grade), from a school in the region of Aveiro. The results revealed that, with increasing age, the rating level of responses tends to increase. The instrument used is in the process of gauging, or external validation, that is, meeting normative data, although it is already subject to adaptation procedures, as it is an original test in Italian. We will give an account of the data obtained and analyzed which, to date, seem to us to be quite promising. Although still preliminary and exploratory, with a sample that is still not very representative and significant, the results appear to be not very distant from the averages obtained by their Italian counterparts.

Not all machining processes are carried out using a CNC (Computer Numerical Control) system, but are started by using conventional machines that do not require a high level of accuracy. In accordance with the advantages it has for product accuracy, most CNC systems are intended for finishing processes. The level of surface roughness of a product is indeed adjusted to the usefulness of the product itself, but it cannot be denied that the better the quality produced, the higher the selling value of the product. This study aims to determine the effect of variations in depth of cut on the wear value of the EndMill Carbide chisel on the SKD 11 steel material used in the manufacture of Dies. This study used a literature study type method, research procedures, first material preparation, second specimen machining procedure, recorded cutting time, looked at the surface of the tool after the cutting process was carried out using a microscope, determined the condition of the tool damage and then re-cut until the tool could not be used again or wear has reached 0.3 mm, then record the cutting length every 5 minutes of cutting and finally data analysis. Based on the results of the test data obtained, it shows that the wear of the carbide endmill (VB) chisel blade from the comparison of machining time and feed rate has a graph, namely if the cutting time is longer, namely 30 minutes. The higher the cutting length, the faster the wear value occurs and vice versa the lower the cutting length value, the smaller the wear value achieved. The type of endmill carbide cutting tool wear that occurs is flank wear.

This study aims to determine the effect of temperature on the tensile strength of polymeric materials that can have the strength used for HDPE with bamboo fibers. This study uses research methods and data collection will discuss starting from the manufacture of recycled HDPE plastic with bamboo fiber, then a Tensile test and Bending Test will be carried out to see the strength of the recycled results. The HDPE recycling process begins with collecting used plastic bottle caps made from HDPE which will be crushed before being put into the Hot Press Machine. Furthermore, the results of the crushing are put into the Hot Press Machine to be recycled into Panel Board Furniture. Based on the results of the test data obtained, it shows that (1) Variations in the addition of bamboo fiber particles to HDPE specimens affect the physical properties which causes the specimens to have a greater elastic modulus value than specimens without the addition of bamboo fiber particles to HDPE. This causes the stress value on the specimen to be greater, and the strain value to be smaller. (2) Pullouts are present in all types of specimens tested. Tensile which can be interpreted as a bond between the reinforced matrix and the matrix is not good or the bond between the bamboo fibers and the HDPE plastic is not fused. (3) The results of the tensile test show that the greater the temperature heated, the weaker the tensile strength will be. thus, the lower the temperature, the stronger the value of the tensile strength. This can be seen from the data from the tensile test results of the HDPE specimens.
