Authors:   Department of General Sciences, College of Basic Education, Haditha, University of Anbar, Iraq, Al-Obaidi Zayd
Published: January 2024

The importance of plastic has emerged in many modern industries, and petroleum is an essential source for the manufacture of many materials of importance in our contemporary life, such as plastic bags, paints, brooms that are used for cleaning, and others. This study showed that it is possible to use these plastic products in other ways to reduce the plastic pollution that invades the world, and one of these ways is the possibility of adding plastic to concrete to improve some of its properties. In this work, the bristles of plastic brooms are used in the form of fibers to improve the properties of concrete, and the results showed a significant improvement in the resistance to compression, flexural, and impact resistance of concrete, in addition to a slight decrease in the density. The fibers were added in different proportions (0.6, 1.0, and 1.4) as a percentage of the concrete volume, and the duration of the test ranged between (7 and 28) days for the tests of compression, flexion, and density, while the impact resistance tested at the age of 90 days.

This work seeks to use both traditional control algorithms and advanced optimization algorithms to enhance the performance of a DC-DC converter. The chosen algorithm was Proportional-Integral-Derivative (PID) based on gray wolf optimization (GWO). The PID controller is known for its ease of control and wide range of industrial applications. This type of controller has been used successfully in many types of systems, such as power electronics, automation systems, robotics, etc., due to its ability to effectively optimize the system's parameters with minimal effort from the user. To test this new technique on a DC-DC converter different simulations were conducted using MATLAB environment where various parameters were set that can simulate various uses for the DC-DC converter within electrical systems. After conducting these tests it was found that PID based on GWO controller had good performance (rise time 0.0004 sec, settling time 0.0001sec) when compared with other traditional controllers (rise time 0.00416 sec, settling time 0.000323sec), reliability, efficiency higher accuracy, low cost, etc. As expected GWO showed better results than conventional methods like PID or PI controllers due to the fact that it’s an evolutionary approach that allows more flexibility during the configuration process.

Published: January 2024

There are variations in the prevalence of stunting cases at the village level in Kerinci Regency. There have been no studies on the spatial distribution and risk factors of stunting cases in Kerinci Regency. This study aimed to determine the risk factors and spatial distribution of stunting. This research was conducted in Kerinci Regency from March to November 2020 using a case-control design and a total sampling technique. The study participants consisted of 223 patients and 223 controls. Children who experienced stunting were recorded at the health office. The controls were non-stunted children with an age range (±3 months) and sex who came from the same village as the cases—data collection through interview techniques and observation of the Mother and Child Health book. The chi-square test, logistic regression, and spatial distribution analysis were performed using the open-source software SatScan 10,1 and ArGIS 3,30. The analysis shows stunting cases clustered in Kayu Aro, Gunung Tujuh, and Keliling Danau Districts. A low father's education level (aOR=1,76), father's height <161 cm (aOR=1,52), mother's height <150 cm (aOR=1,83), and incomplete immunization status (aOR=1,6) were risk factors for stunting. In conclusion, cases of stunting clustered in three sub-districts, and the leading risk factor was the mother's height. The health office should make specific intervention efforts before and during pregnancy and focus on cluster-indicated areas.

Setiap fasilitas kesehatan seperti rumah sakit, klinik dan puskesmas yang bekerjasama dengan BPJS wajib melakukan klaim pembiayaan atas perawatan kesehatan terhadap pasien menggunakan tarif INACBG’s  (Indonesian - Case Based Groups). Tarif INACBG’s merupakan paket layanan yang didasarkan kepada pengelompokan diagnosa penyakit yang menggunakan kode ICD-10. Penelitian ini bertujuan menemukan pola frekuensi pada dataset INA-CBG’s terutama  kombinasi diagnosa agar diketahui kombinasi diagnosa apa saja yang sering muncul untuk bahan evaluasi lebih lanjut oleh pihak manajemen fasilitas kesehatan. Penelitian ini membandingkan kinerja Algoritma Apriori, FP-Growth dan Eclat. Nilai Akurasi Lift Ratio dan Rule Asosiasi ketiga algoritma didapatkan nilai yang sama, tetapi untuk waktu komputasi dan pemakaian memori pada Algoritma Eclat lebih banyak daripada Algoritma Apriori dan Fp-Growth, maka dapat disimpulkan bahwa Algoritma FP-Growth dan Apriori lebih cocok untuk dijadikan solusi dalam menemukan pola frekuensi pada dataset INACBG’s.
Rasszizmusváltozatok és dokufikciós kritikáik : A Jöjj vissza, Afrika és a Csépl? Gyuri összehasonlító elemzése
Authors: Müllner András
Published: January 2024

Tanulmányomban az amerikai független filmes Lionel Rogosin magyarországi fogadtatását vizsgálom, valamint hatását olyan filmrendezőkre, mint Schiffer Pál. Rogosin háborúellenes, hatalomkritikus és antirasszista filmjei könnyen adaptálhatók voltak a hivatalos magyarországi kultúrpolitika antiimperialista, antikapitalista és kommunista ideológiai és esztétikai álláspontjához, ugyanakkor módszere szintén kapóra jött a romák filmes ábrázolásában épp holtpontra jutott magyar rendezőnek. Az első repedés a belső gyarmatosítást végrehajtó, öntudatlanul is a fehér felsőbbrendűség ideológiáján alapuló hatalom reprezentációs politikáján Schiffer 1977-es fikciós dokumentumfilmje, a Cséplő Gyuri volt. Schiffer részvételi jellegű szituációs és improvizációs technikái Rogosin Jöjj vissza, Afrika című filmjének hasonló módszereire emlékeztethetik a nézőt, és ennek folytán a Cséplő Gyurit a filmes dekolonializmus magyar példájaként tarthatjuk számon, amely a magyar romák társadalmi helyzetét és az ellenük irányuló diszkriminációt elemzi a romák cselekvőképességének bemutatásán keresztül.
„Vidéki elégia”, avagy napjaink társadalmi folyamatainak dokumentumfilmes ábrázolása Sáp példáján
Authors: Biczó Gábor
Published: January 2024

A tanulmány egy marginális helyzetű kelet-magyarországi településen készült dokumentumfilm alapján vizsgálja a magyar-roma etnikai együttélési helyzet egy esetét és a vizuális ábrázolás vonatkozó nehézségeit. A szociális szakemberként tevékeny főhős monológja betekintést enged a politika rendszerváltást követően kibontakozó deprivációs folyamatokba, amelyek számtalan magyarországi vidéki lokális társadalomban hasonló módon játszódnak le. Az antropológiai szemléletű film és a vonatkozó elemzés célja, hogy az olvasót tájékoztassa azokról a szociokulturális jelenségekről, amelyek elkerülhetetlenül válnak társadalmunk egyre fontosabb közügyeivé.
Consideration on the world afterward of Informatization
Authors: Vourkoutiotis Sifis Sato
Published: January 2024

The document titled "Consideration on the world afterward of Informatization" provides a comprehensive analysis of societal changes, with a particular focus on Japan, though applicable globally. It discusses the transition from an industrial to an "Assessonomic society", the evolving role of science and technology, a comparison of the lifestyles and values of ancient people with those of the modern era, and the changing perceptions and values towards science. Here I argue that the limitations of science, declining public trust in scientists, and the changing role of mass media have led to a loss of societal faith and dreams about science. These factors indicate a shift away from scientism, as people begin exploring other values.

Berdasarkan hasil perbandingan antara jurnal dan grafik jominy test, dapat disimpulkan bahwa pembentukan austenit yang dikembalikan dapat menurunkan kekuatan material. Hal ini ditunjukkan oleh hasil uji kekerasan yang lebih rendah pada spesimen yang mengalami perlakuan penuaan daripada spesimen yang tidak mengalami perlakuan penuaan pembentukan austenit yang dikembalikan dimulai pada tahap awal perlakuan penuaan dan terus meningkat seiring dengan lamanya penuaan. Namun, grafik jominy test hanya menunjukkan hasil uji kekerasan pada spesimen yang mengalami perlakuan penuaan selama 0,25 jam.Untuk mendapatkan gambaran yang lebih lengkap tentang pengaruh waktu penuaan terhadap pembentukan austenit yang dikembalikan, perlu dilakukan pengujian jominy pada spesimen dengan waktu penuaan yang berbeda.Secara keseluruhan, hasil perbandingan antara jurnal dan grafik jominy test menunjukkan bahwa pembentukan austenit yang dikembalikan dapat menurunkan kekuatan material. Namun, untuk mendapatkan hasil yang lebih akurat, perlu dilakukan pengujian jominy dengan waktu penuaan, suhu penuaan, dan komposisi kimia yang sama dengan yang digunakan dalam jurnal tersebut.
Pengaruh Temperatur Austenit Pengujian Jomini Test Pada Sifat Hardenability Baja ST-42 dan Besi Ulet

Dari hasil dan pembahasan dapat disimpulkan bahwa spesimen yang diaustenisasi pada suhu 830o mempunyai nilai kekerasan tertinggi dan distribusi kekerasan yang lebih sesuai. Sedangkan untuk spesimen yang diaustenisasi pada suhu 780o kekerasannya lebih rendah untuk struktur mikro campuran yang diaustenisasi sebagian. Spesimen yang diaustenisasi pada suhu 880o mempunyai kemampuan pengerasan yang baik, namun struktur mikro yang kasar pada suhu austenitisasi yang lebih tinggi mempengaruhi kekerasan secara signifikan. Sedangkan hasil pengujian yang dilakukan pada baja ST-42 sebelum heat treatment (suhu ruangan) nilai kekerasannya tak menentu tiap titik pengujiannya dimana nilai kekerasannya naik turun. Pada titik awal nilai kekerasannya berada pada nilai 49 dan menurut sampai titik ke tiga. Namun pada titik ke empat nilai kekerasannya naik begitupun seterusnya. Hal ini juga sama dengan baja ST42 heat treatment pada suhu 800o di mana nilai kekerasannya tak menentu tiap titiknya.
