Abstract
Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver a scientific opinion on the tolerable upper intake level (UL) for iron. Systematic reviews were conducted to identify evidence regarding high iron intakes and risk of chronic diseases, adverse gastrointestinal effects and adverse effects of iron supplementation in infancy, young childhood and pregnancy. It is established that systemic iron overload leads to organ toxicity, but no UL could be established. The only indicator for which a dose–response could be established was black stools, which reflect the presence of large amounts of unabsorbed iron in the gut. This is a conservative endpoint among the chain of events that may lead to systemic iron overload but is not adverse per se. Based on interventions in which black stools did not occur at supplemental iron intakes of 20–25 mg/day (added to a background intake of 15 mg/day), a safe level of intake for iron of 40 mg/day for adults (including pregnant and lactating women) was established. Using allometric scaling (body weight0.75), this value was scaled down to children and adolescents and safe levels of intakes between 10 mg/day (1–3 years) and 35 mg/day (15–17 years) were derived. For infants 7–11 months of age who have a higher iron requirement than young children, allometric scaling was applied to the supplemental iron intakes (i.e. 25 mg/day) and resulted in a safe level of supplemental iron intake of 5 mg/day. This value was extended to 4–6 month‐old infants and refers to iron intakes from fortified foods and food supplements, not from infant and follow‐on formulae. The application of the safe level of intake is more limited than a UL because the intake level at which the risk of adverse effects starts to increase is not defined.
Enhancing ESL learners' executive function and cognitive ability: A hybrid approach of situated learning and task-based language teaching

Published: June 2024

In the contemporary era of globalization, learning a second language has become a pivotal means to broaden individual perspectives and enhance competitiveness. English, as the lingua franca of international communication, assumes particular importance. This paper delves into the integrated application of situated learning (SL) and task-based language teaching (TBLT) in English as a Second Language (ESL) instruction, aiming to augment learners' executive function (EF) and cognitive ability (CA). SL theory underscores the interplay between learning and context, whereas TBLT emphasizes task-centric pedagogical approaches. These two methodologies share numerous parallels in ESL instruction, both prioritizing the cultivation of students' active participation and communicative competencies. Consequently, the integration of SL with TBLT mutually catalyzes, collectively enhancing students' learning outcomes. In the design and implementation of ESL instruction, a framework comprising stages such as preparation, introduction, task preparation, task implementation, task completion, language feedback, language summary, and task evaluation is proposed to ensure the effectiveness and appeal of teaching. Despite potential challenges in practice, such as insufficient teaching resources, the complexity of instructional implementation, and imperfect assessment and reflection mechanisms, the integrated approach of SL and TBLT still harbors immense potential and value. Thus, further in-depth research and practice are warranted to explore this integrative teaching methodology.
Conversations and Reflections on Authentic Assessment
Authors: Grant Kimberley , Fedoruk Lisa , Nowell Lorelli
Published: June 2024

In this paper, we describe how academic colleagues from different fields used a theoretical framework for authentic assessment as the starting point for meaningful conversations about our teaching practices. We re-envision Hutchings’ (2000) taxonomy of SoTL questions as a fluid conversational cycle rather than a system of classification. Using the eight elements of authentic assessment as outlined by Ashford-Rowe et al. (2014) as a theoretical framework, we engage with the research literature, reflect on what is and what works from our previous teaching and learning experiences, and propose ideas and questions for what is possible moving forward.
Field Theory, Intercorporeality, and the Sámi Underworld
Authors: Éowyn Nelson Elizabeth
Published: June 2024

Field theory as a concept entered scientific discourse in the mid-nineteenth century. Yet the essential features of a field long predate discoveries about the physical properties and behavior of matter. The paper briefly describes ancient esoteric precursors to scientific field theory, including the Hermetic tradition and archetypal astrology, before turning to twentieth-century sociological field theories and their elemental idea of subjectivity and intersubjectivity. Jungian psychology is a field theory, expanding the limits of sociology in important ways. The paper adopts a somatic archetypal perspective to argue that intersubjectivity, the basis of sociological and psychological field theories, is inadequate. Instead, depth psychologists should embrace intercorporeality, the more embodied, holistic field theory originating in the work of Husserl and Merleau-Ponty. The paper concludes with a discussion of nekyia to illustrate how an intercorporeal field theory can include the underworld in world mythologies. The inverted cosmic geography of one tradition, the Sámi, gives new meaning to numinous encounters with one’s ancestors and spirit guides. Such encounters intertwine the subtle energy bodies of the personal and transpersonal worlds, a meeting one can imagine as soul to sole, not just soul to soul.

Food problems are a very serious topic globally. This does not only include basic food ingredients such as grains, tubers or other substitute ingredients, but also includes the need for supporting ingredients such as fruit. One of the fruit commodities that many people need is melon (Cucumis melo L.). The availability of melons on the market is currently dominated by farmers' seasonal crops, so their availability is relatively limited outside the season and a surplus during the season, so this has an impact on price stability, both for farmers and consumers. One method that can be offered for this problem is how to carry out cultivation that is not tied to the season by using a greenhouse combined with hydroponic or conventional drip irrigation cultivation methods. The results show that the use of hydroponic methods and drip irrigation can stimulate the growth and especially the development of melon plants. The appearance of flowers in the hydroponic system starts at 2-3 WAP, while in the drip irrigation system it starts at 3-4 WAP. The emergence of productive branches in both methods also takes place from the age of 2 WAP and continues to grow. So from several aspects such as optimal growth, long-term cost efficiency, sustainable agriculture and efficient use of water for agriculture, these two methods can be an effective alternative for melon cultivation.

Published: June 2024

The performance enhancement of clutch actuation control process in electro-pneumatic clutch system for heavy duty vehicles through the application of Artificial Neural Network control is addressed in this presentation. The inability of some heavy-duty vehicles to operate optimally on hilly terrains due to inadequate compression or torque and which often leads to accidents can be traced to inadequacies in clutch actuation control. Conventional control techniques in clutch actuation uses on/off, servo mechanism and other non-intelligent methods of actuation control. These conventional techniques demand for frequent calibration of clutch actuators. Often times, this important requirement is neglected with attendant ugly consequences. To eliminate calibration and its observed defects, an intelligent method of clutch actuation modelled in an Artificial Neural Network control is implemented. Conventional data obtained for piston error signals, speed, torque and power from a Mercedes Benz Actros Truck model MP 2, 2031 provided the reference points. These data were fed into a developed ANN that was subjected to a standard training algorithm to achieve the intelligence control for electro-pneumatic clutch actuation. The Backpropagation method of weight adjustments and the application of Sigmund activation functions featured. Simulink models which imbedded design parameters for both conventional and ANN controllers were also developed and simulated. Different percentages of improvements were recorded for piston error, engine torque, angular speed and power respectively. In order to justify the research, the level and percentage of improvements were determining. ANN improved by 0.4821mm or 33.04 % decrease for error, increases of 334.1 RPM or 33 % for angular speed, 0.0594NM or 33.26 % for torque and 2.79 watts or 16.53 % for power respectively were recorded. These results depicts conclusively that ANN controller application in intelligent clutch actuation control of an electro-pneumatic clutch actuation system for heavy-duty vehicle will be remarkable. Its impact in the smooth operation of heavy-duty vehicles will indeed eliminate completely the attendant calibration problems and associated poor performances with conventional controllers in electro-pneumatic clutch actuation systems.

Published: June 2024

This study proposes an economic production quantity (EPQ) model that comprehensively addresses scrap items, imperfect quality items, rework processes, and shortages. The model incorporates various types of defective items, including scrap, imperfect quality, and rework able items, and implements immediate rework processes upon the completion of regular production. Shortages are treated as lost sales, enhancing the accuracy of inventory cost estimations. Numerical experiments demonstrate the opti­mal­ity of production lot sizes and underscore the impact of production and demand rate adjustments on overall inventory costs. Sensitivity analysis further elucidates the influence of imperfect quality items on inventory costs. This EPQ model offers a comprehensive approach to efficient and effective finished product inventory management by integrating consider­ations for scrap items, imperfect quality items, and rework processes. Addi­tionally, a furniture manufacturing company case is presented to illustrate the practical application of the proposed model.

Published: June 2024

Durian (Durio zibethinus murr) was a tropical fruit from Southeast Asia. Based on the content, the durian peel waste has the potential to be used as a raw material in the process of making oxalic acid. The cellulose content found in durian peel is 50-60%, and there was lignin and starch content of 5% for each. Oxalic acid is an organic compound with the formula C2H2O4. This study aimed to determine the effect of nitric acid concentration and oxidation time of durian peel on yield, oxalic acid content, and the quality of the oxalic acid produced. The method used in this study was the oxidation process. The influential variables in the oxidation process with nitric acid were the concentration and heating time. The higher the nitric acid concentration, the greater the % yield of oxalic acid produced. The independent variables used were nitric acid concentration and time. This research used a factorial Completely Randomized Design (CRD) method with two factors, namely nitric acid concentration (HNO3) and reaction time, and nine treatment combinations were obtained. The concentrations used were 3 M, 4 M, and 5 M then the times used were 60, 70, and 80 minutes. The ratio between nitric acid and durian peel was 1:10 with a temperature of 75℃. The optimum yield occurred at a concentration of 4M HNO3 with a heating time of 80 minutes, where the yield obtained was 22.50%. Oxalic acid from a citric acid concentration of 5M and a reaction time of 80 minutes resulted in oxalic acid crystals melting at 98.6˚C. From the results of this analysis, the synthesized oxalic acid has the same characteristics as pure oxalic acid, so it can be concluded that the product produced from this research is oxalic acid and is classified as dihydrate oxalic acid.

Published: June 2024

Coffee is usually consumed by adding sugar, cream, or milk. Adding these ingredients, especially sugar, can cause new disease problems. The market is starting to look for natural sweeteners that do not cause health problems, such as stevia. The objective of this research was to identify the sensory attributes and chemical components of some variety of stevia coffee formulations. Sensory attributes were identified through a focus group discussion (FGD), and sensory profiling to choose the best formulation was determined using the Rate-All-That-Apply (RATA). The FGD members were nine panelists, while the RATA sensory evaluation used 30 panelists. Chemical analysis carried out includes water (gravimetry), ash (gravimetry), and antioxidant capacity (spectrophotometry). In this research, four distinct formulations of stevia coffee,  A1 (0% stevia), A2 (2% stevia), A3 (4% stevia), and A4 (7% stevia), were utilized.   Results indicate that varying stevia concentrations significantly influence the resulting coffee's sensory characteristics. Attributes identified through FGD include color (dark brown), aroma (green/leafy, sour, roasted, spicy), taste (acid/sour, sweet, bitter, green, spice) and aftertaste (over, bitter and sweet). Statistical analysis showed that eight out of thirteen sensory attributes had significant differences (p<0.05) among the four samples. Sensory evaluation of the selected sample, A2 (4%), revealed a favorable taste profile characterized by sweetness and sourness. Moreover, the chosen formulation exhibited a notable antioxidant activity level of 83.13%. These findings underscore the potential of stevia coffee as a flavorful and health-conscious alternative, offering valuable insights for product development and consumer acceptance.

Tulisan ini bertujuan untuk menganalisis peran penting kemandirian kekuasaan kehakiman dalam menjaga prinsip negara hukum di masyarakat demokratis. Negara hukum merupakan fondasi yang vital dalam sistem politik yang demokratis, karena menjamin perlindungan hak asasi manusia, keadilan, dan kepastian hukum. Namun, ketika kekuasaan kehakiman tidak mandiri, risiko penyalahgunaan kekuasaan dan pelanggaran hak-hak individu meningkat. Dalam konteks masyarakat demokratis, kemandirian kekuasaan kehakiman menjadi aspek yang sangat penting. Hal ini memastikan bahwa keputusan yang diambil oleh pengadilan didasarkan pada hukum dan bukan dipengaruhi oleh kepentingan politik atau tekanan eksternal. Kemandirian kekuasaan kehakiman juga memungkinkan pengadilan untuk bertindak sebagai pengawas terhadap pemerintah dan lembaga-lembaga publik lainnya, sehingga dapat mencegah penyalahgunaan kekuasaan dan menjamin perlakuan yang adil bagi semua warga negara. Namun, tantangan dalam menjaga kemandirian kekuasaan kehakiman di masyarakat demokratis tidak dapat diabaikan. Beberapa faktor seperti campur tangan politik, tekanan dari kekuatan ekonomi, dan kurangnya sumber daya yang memadai dapat mengancam kemandirian tersebut. Oleh karena itu, perlunya langkah- langkah yang kuat untuk memperkuat kemandirian kekuasaan kehakiman, seperti penegakan etika kehakiman, pemilihan hakim yang transparan, dan sistem pengawasan yang efektif. Dalam kesimpulannya, kemandirian kekuasaan kehakiman merupakan pilar penting dalam menjaga negara hukum di masyarakat demokratis. Dengan menjaga kemandirian tersebut, masyarakat dapat memiliki keyakinan bahwa pengadilan akan menegakkan keadilan, melindungi hak-hak individu, dan memastikan kepastian hukum. Oleh karena itu, peran aktif masyarakat dalam mendukung kemandirian kekuasaan kehakiman sangatlah penting dalam membangun negara hukum yang kuat di masyarakat demokratis.

Abstrak
Standar kualitas produk yang ditetapkan perusahaan dapat dijaga melalui metode kontrol kualitas produk yang tepat. Kain hasil produksi PT X masih memiliki cacat produk melebihi batas toleransi perusahan yaitu maksimal 2%. Jenis cacat kain diantaranya warna tidak OK  (WTO), crease mark dan kotor warna, sehingga perlu dilakukan analisis untuk mengontrol kualitas produk pada tiap prosesnya, menggunakan metode kontrol kualitas statistik (SQC).  Kontrol kualitas statistik dapat mendeteksi kesalahan proses atau penyebab khusus melalui analisis data yang sudah lampau maupun yang ada saat ini. Pada hasil p-chart ditemukan data kain rayon viskosa 100% mengalami penyimpangan, ditunjukkan dengan adanya titik-titik yang fluktuasinya tinggi dan tidak beraturan, artinya produk cacat banyak diluar batas kendali. Melalui analisis diagram tulang ikan (fish bone) diketahui faktor penyebab cacat kain pada proses produksi, diantaranya pekerja, material, metode dan peralatan. Berdasarkan data kontrol kualitas statistik yang diperoleh dapat dilakukan perbaikan.
Kata Kunci: kontrol kualitas, cacat, peta p, diagram tulang ikan
