Authors: Anggraeni Novi , Listiana Aan
Published: April 2023

Early Childhood Education (PAUD) is a critical stage in a child's development that lays the foundation for lifelong learning and success. The use of technology in PAUD is effective for improving learning and development outcomes. Contemporary pedagogical technologies such as interactive media, mobile applications, and educational software have been identified as potential tools for improving the quality of ECD. This literature review aims to analyze efficacy of educational technology in boosting the learning and development of young children. In this literature review, the writers selected relevant and accurate studies from restricted academic sources such as Scopus and Crossref to gather research data, which were then categorized according to PRISMA criteria. The first search yielded 134 articles, which were then whittled down to 20 papers acceptable for closer examination. This study results reveal a lack of instructor competency in the use of technology among ECE classroom instructors, preventing educators from focusing on the use of technology in early childhood education. This is due to the fact that early childhood educators are less equipped for the theory and practice of modern educational technologies, such as learning software, mobile apps, and interactive media, which may increase the cognitive, linguistic, and social capacities of young children. In the meanwhile, educational technology may assist in bridging the learning gap between children with special needs and those without access to formal schooling.

Europe’s Water Crisis: From Overshadowed to Potentially Catastrophic
Authors: Azis Aswin A. , Alfarizi Muhammad F.
Published: April 2023

Water crises and scarcity can be seen as a result of the recent heat wave in Europe. The problem has been occurring in many countries for many years, so from a general point of view the water crisis may seem normal. However, Europe's drought and water crisis is now reported to be the worst in 500 years. Water crises could be chartered as national priorities that, at worst, could spark conflict on a global scale. Unfortunately, at the same time, the water crisis not only overshadowed by major political issues, but also other environmental issues. In order to better understand and analyze the global water crisis and climate change, green theory is used as a theoretical basis for the discussion. Through green theory, we can understand that Europe's water crisis is a cause of its own actions, becoming an environmental injustice through its effects. To solve the water crisis, Europe can participate in the 2023 UN Water Conference and implement reductions in water consumption. Europe's future depends on how successful it is in finding the best solutions. If left unchecked, Europe's future could be bleak.

Published: April 2023

The study of the metaplasticity-based transcranial magnetic stimulation (TMS) protocols is an extensively studied approach to increase the effectiveness of stimulation. However, the effects of protocols with different intervals between the TMS blocks on cognitive functions are poorly understood. The study was aimed to assess the effects of two theta-burst transcranial stimulation (iTBS) protocols with short and long intervals between blocks on the working memory (WM) performance in healthy volunteers. A total of 16 participants were underwent a single TMS session of each protocol, which were applied in random order (iTBS 0–15 — two iTBS blocks over the left dorsolateral prefrontal cortex (DLPFC) iTBS with an interval of 15 min between blocks followed by stimulation of the vertex area in 60 min after the first block; iTBS 0–60 — iTBS block over the left DLPFC iTBS, block of the vertex stimulation after 15 min, and the second block of iTBS over the left DLPFC iTBS 60 min after the first one; iTBS 0 — one block of iTBS over the left DLPFC iTBS and two blocks of the vertex stimulation; control protocol — three blocks of the vertex stimulation with similar intervals). WM was assessed using the n-back test before the first block and after the second and the third stimulation blocks. No significant effects of protocols on WM or differences between protocols in alterations of test results and the responder rates to TMS between protocols were observed. The trend toward statistical signficance was reported for the protocol with short interval (iTBS 0–15). Furthermore, low reproducibility of individual iTBS effect was reported. The study of protocols with short intervals between blocks involving larger cohort of volunteers and taking into account the other factors potentially influencing the effect of the protocol (number of blocks and duration of a single block) seems to be promising.

Kerusakan kayu yang disebabkan oleh jamur merupakan masalah serius karena menurunkan kualitas kayu. Pengawetan kayu menggunakan bahan kimia sintetis selama ini menimbulkan dampak terhadap lingkungan.  Penelitian ini bertujuan untuk mengevaluasi sifat antijamur asap cair dari kayu akasia (Acacia crassicarpa) dan kayu jelutung (Dyera costulata) dalam menghambat pertumbuhan jamur S. commune yang dilaksanakan secara vitro. Asap cair dari kayu akasia diperoleh dari pembakaran secara konvensional tanpa pengontrolan suhu, sementara asap cair dari kayu jelutung diproduksi melalui proses pirolisis pada suhu 400°C. Penelitian ini terdiri dari dua set percobaan berdasarkan jenis asap cair yang digunakan. Setiap percobaan disusun menggunakan rancangan acak lengkap yang terdiri dari lima perlakuan, yaitu perlakuan kontrol (0%, tanpa asap cair), dan empat konsentrasi asap cair dengan konsentrasi 1,0; 2,0; 3,0 dan 4,0 %, v/v. Percobaan dilaksanakan dengan metode pengujian makanan beracun secara in vitro menggunakan media potato dextrose agar (PDA) sebagai media pertumbuhan jamur S. commune. Hasil penelitian menunjukkan bahwa asap cair dari kayu akasia tidak mampu menghambat pertumbuhan jamur sampai konsentrasi tertinggi, sementara asap cair dari kayu jelutung memiliki aktivitas antijamur dan telah mempu menghambat pertumbuhan jamur S. commune secara maksimal (100%) pada konsentrasi 2%.

Tujuan penelitian ini adalah mengetahui respon pertumbuhan enam varietas tanaman padi (Oryza sativa L.) terhadap serangan pengerek batang. Penelitian ini dilaksanakan di lahan bukaan baru Kampung Bokem, Distrik Merauke, Kabupaten Merauke, Propinsi Papua Selatan pada bulan Maret Sampai Juni 2021. Penelitian dilakukan dengan menggunakan Rancangan Acak Kelompok (RAK) terdiri atas 6 varietas dengan 3 ulangan. Varietas yang digunakan, yaitu varietas Nutrizinc, Mamberamo, Inpari 42, Inpara 2, Inpari 32 dan Inpari Sidenuk.  Masing masing perlakuan diulang sebanyak 3 kali ulangan sehingga akan diperoleh 18 plot percobaan. Luas plot pengamatan 3 x 3 m2 dengan jarak tanam 20 x 20 cm sehingga dalam plot terdiri dari 50 tanaman.  Hasil penelitian menunjukkan bahwa terdapat variasi tinggi pada masing-masing varietas sebagai berikut: varietas Chidanu (78,4 cm), varietas padi Inpara (74,2 cm), varietas Nutrizinc (70,7 cm), varietas Mambramo (66,3 cm), varietas Inpari 42 (65,1 cm) dan varietas Inpari 32 (59,0 cm). Demikian pula dengan jumlah anakan yaitu varietas Inpara 2 (12 anakan), varietas Inpari Chidanu (11 anakan), varietas Inpari 32 (10 anakan), varietas Mambramo (10 anakan), dan varietas Inpari 42 (9,0 anakan).  Jumlah anakan terserang serangga pengerek batang berturut-turut adalah varietas Inpara 2 (9 anakan), varietas Inpari 42 (7,0 anakan), varietas Inpari Chidanu (5,6 anakan), varietas Inpari 32 (5,5 anakan), varietas Nutrizinc (4,4 anakan) dan varietas Mambramo (4,3 anakan). Gabah paling paling banyak terdapat pada varietas Inpara 2 (186,2 gabah) sedangkan terendah pada varietas Nitrizinc (119,4 gabah). Respons enam varietas padi yang diteliti memiliki tingkat kerentanan yang berbeda-beda terhadap serangan penggerek batang (Scirpophaga sp). Varietas Nutrizinc dan Mambramo menunjukkan rata-rata tingkat serangan terendah terhadap serangan hama pengerek batang pada lahan bukaan baru (4,3 anakan).
