Published: March 2024

Education in elementary schools has a central role in forming students' character and independence. The Merdeka Curriculum as an innovation in the field of education in Indonesia emphasizes student independence and the development of their potential. However, its implementation requires a deep understanding of the legal aspects of education. The juridical basis is key in ensuring the conformity of the Merdeka Curriculum with the applicable legal framework. The aim of this study is to explores the role of juridical foundations in implementing the Merdeka curriculum in elementary schools. This research was designed using qualitative methods using a library research approach (literature review). The research results show that the Pancasila educational philosophy has to become the main foundation in the national education system. Pancasila recognizes the truth of knowledge that comes from revelation, reason and experience. As a regulatory norm that must be upheld, Pancasila is a guideline in the legal order in Indonesia. A deep understanding of Pancasila values is very important in realizing education that reflects its basic principles. It is hoped that the consistent application of the Pancasila educational philosophy can encourage the realization of Indonesian human development in accordance with the values reflected in Pancasila as the state philosophy and ideology.

Capturing the diversity of mesoscale trade wind cumuli using complementary approaches from self-supervised deep learning
Authors: Chatterjee Dwaipayan , Schnitt Sabrina , Bigalke Paula , Acquistapace Claudia , Crewell Susanne 
Published: March 2024

At mesoscale, trade wind clouds organize with various spatial
arrangements, shaping their effect on Earth’s energy budget.
Representing their fine-scale dynamics even at 1 km scale climate
simulations remains challenging. However, geostationary satellites (GS)
offer high-resolution cloud observation for gaining insights into trade
wind cumuli from long-term records. To capture the observed
organizational variability, this work proposes an integrated framework
using a continuous followed by discrete self-supervised deep learning
approach, which exploits cloud optical depth from GS measurements. We
aim to simplify the entire mesoscale cloud spectrum by reducing the
image complexity in the feature space and meaningfully partitioning it
into seven classes whose connection to environmental conditions is
illustrated with reanalysis data. Our framework facilitates comparing
human-labeled mesoscale classes with machine-identified ones, addressing
uncertainties in both methods. We highlight the potential to explore
transitions between regimes, a challenge for physical simulations, and
illustrate a case study of sugar-to-flower transitions.
Rethinking Islamic Da'wah Model in the Context of Digital Space
Authors: Adeni Adeni , Hakim Lukmanul , Hasanah Silviatul 
Published: March 2024

The presence of the digital era has changed the orientation of da'wah. Da'wah has changed from merely a doctrinal activity (to Islamizing infidels) to an activity of exchanging religious narratives between people in cyberspace. This fact requires rethinking the concept of the da'wah model. By reviewing primary da'wah scientific literature, such as the works of Abdul Karim Zaedan and Al-Bayanuni, researchers explore how the traditional Islamic da'wah model has been built so far, and then observe online da'wah sites in Indonesia to build a new model of da'wah. This study finds that the old elements of Islamic da'wah have changed in the digital context. The relationship between the elements of da'wah in the digital space is strongly controlled by the media platform used. The relationship between the preacher and the recipient of the da'wah is no longer linear or one-way but multi-directional. The preacher no longer holds full authority in the message he conveys because the critical and active recipient can freely interpret the message according to his wishes and background. In addition, the relationship between the preacher and the recipient is determined by various buttons on a platform. The choice of buttons: like, dislike, comment, subscribe, and di-subscribe, has eliminated the domination of the preacher over the recipient. This finding reflects a new model of Islamic da'wah, namely da'wah that encourages the exchange of religious discourse between people, opens space for various alternative religious progressive thoughts, fosters religious maturity, closes the dominance of the truth of one particular group, and creates an open and democratic religious space.

Abstract
Ongoing coniferous monocultures decline in Beskydy Mts. Slovakia, emerged into establishment of Demonstration object of reconstruction of spruce forests (DORS) Husárik, focused on various technological processes of regeneration of economically important tree species. For Norway spruce (Picea abies [L.] Karst.) assessment of less frequently used artificial regeneration technologies, including planting of containerized transplants (CRT) or direct seeding procedures (direct seeding DS, seeding into vegetation cell VCS) and commonly used planting of bareroot transplants (BRT) was carried out. Seven years after experimental plot establishment, the lowest survival rate was recorded for DS treatment with 42% survived seedlings, the highest for CRT treatment with 79% survived transplants. For germinated seedlings, average seeding spot occupation rate recorded for DS (72%) was significantly lower than for VCS (98%) one year after seeding and remained significantly lower also over further consecutive years. Average survival recorded for planted transplants over monitored period did not differ markedly and gradually decreased to 76% for BRT and 79% for CRT. Reflecting different ontogenetic stage of individuals assigned to selected treatment average height 134.6 cm for DS, 134.1 cm for VCS and 182.0 cm for CRT, 215.0 cm for BRT was recorded seven years after establishment. The results suggest that for spruce, less frequently used artificial regeneration technologies (VCS, CRT), that markedly curtail time period required for target tree species installation on planting sites, with survival and growth rate of plants recorded in this study, could provide reasonable alternative to commonly used planting of BRT.

Abstract
Resistance of horse chestnut Aesculus hippocastanum ‘Mertelík’ to Cameraria ohridella was proven in the trial under semi-field conditions. Seedlings of vulnerable and resistant trees were grown together in rearing cages and were exposed to the strong attack from C. ohridella larvae. Significant differences in leaflet injuries were observed between susceptible and insect-resistant trees. Variety ‘Mertelík’ showed almost none or very small damages compared to high defoliation level in case of standard trees. The results confirmed that this resistant clone could be suitable for use under field conditions.

Background:Although rare, cases of hypophysitis resembling a pituitary abscess (PA) have been reported. Differential diagnosis between hypophysitis and PA is crucial as the two diseases require different treatments.Case Description:A 38-year-old woman with headaches underwent head magnetic resonance imaging (MRI), which revealed an 11-mm mass lesion in the sella turcica. Due to breastfeeding, contrast-enhanced MRI was avoided. Pituitary adenomas and Rathke’s cleft cyst (RCC) were suspected, and she was initially treated conservatively. Five months later, she acquired syndrome coronavirus two infections, and while the fever subsided with acetaminophen, the headache persisted. One month later, the headache worsened, followed by fever and diabetes insipidus. MRI revealed a pituitary cystic mass with ring-shaped contrast enhancement on T1-weighted MRI and increased signal intensity on diffusion-weighted imaging (DWI). PA was suspected, and emergency endoscopic transsphenoidal surgery was performed. The microbiological examination of the yellowish-brown content drained from the cystic mass was negative. Microscopically, the cystic lesion was covered with ciliated columnar epithelium and stratified squamous epithelium, with a dense inflammatory cell infiltrate consisting mainly of lymphocytes and plasma cells observed around the cyst. This supported the diagnosis of secondary hypophysitis associated with RCC without PA.Conclusion:We report a case of hypophysitis secondary to RCC resembling PA with ring-shaped contrast enhancement on MRI and increased signal intensity on DWI. This case emphasizes the need for cautious diagnosis of secondary hypophysitis due to RCC in individuals with MRIs and clinical manifestations resembling an abscess.
