Abstract

Based on the results of observations conducted by researchers at SD Negeri Jatimulyo, Pati Regency, problems were found in the form of limited learning media and student learning outcomes that were still in the low category on the material of the earth's layers. Based on these problems, it aims to improve the learning outcomes of fifth grade students at SD Negeri Jatimulyo, Pati Regency. This study is based on constructivist theory and Vygotsky's learning theory, emphasizing the importance of peer interaction and cooperative learning in cognitive development. The Smart Box learning media, designed as a real learning tool, combines material summaries, images, experiments, and games to facilitate understanding and engagement among students. The type of research used is R&D research and development using the Brog and Gall model which was modified into 8 stages. The results of the product research showed that the Smart Box learning media was very effective, achieving a validation score of 86% and 87% from media and material experts. The effectiveness of the media using the T test obtained a significant value of 0.00. Student learning outcomes are evidenced by the results of the pretest and posttest. The results of the N-Gain calculation obtained a value of 0.61 with the criteria of "moderate". These findings indicate that the Smart Box learning media is a valuable resource for teachers and can significantly increase students' motivation and understanding in learning about the layers of the earth

Abstract

Rainfall prediction is crucial for urban planning, agriculture, and disaster mitigation. This study predicts rainfall intensity in Mataram City using the Gated Recurrent Unit (GRU), a variant of Recurrent Neural Networks (RNN) optimized for sequential data. The dataset consists of hourly rainfall data from NASA's MERRA Power (2010–2021). Data preprocessing includes normalization, feature engineering, and dataset splitting. The GRU model architecture comprises input, GRU, and dense layers. Model performance is evaluated using Root Mean Squared Error (RMSE), yielding 67, 112, 69, and 109 for Ampenan, Cakranegara, Majeluk, and Selaparang, respectively. Results show that the GRU model captures rainfall trends but has limitations in predicting extreme values. This study demonstrates GRU’s potential for improving rainfall forecasting while highlighting the need for further optimization to enhance accuracy.

Abstract

This study aims to analyze the impact of restricting women's rights on the development of civilization, focusing on the condition of women in Afghanistan after the Taliban regained power. The method used is qualitative analysis with a descriptive approach based on secondary data from international reports, scholarly articles, and reliable news sources. The study results show that restrictions on women's rights and roles in various aspects of life, such as education, employment, and social participation, negatively affect societal and civilizational progress. The discussion reveals that the systemic injustice experienced by women in Afghanistan not only suppresses individual rights but also slows down the country's social and economic development. In conclusion, policies that limit women's roles can hinder or even halt the progress of civilization, highlighting the need for global efforts to promote gender equality and the protection of human rights.

Abstract

Mangrove is a coastal ecosystem that absorbs and stores carbon as organic carbon in sediment. The high value of organic carbon in mangrove sediment is influenced by one factor: organic input from the river. This study aims to analyze the effect of the river's total organic carbon (TOC) on TOC stored in mangrove sediment. The samples used were water samples analyzed by the TOC analysis method and sediment samples taken at a depth of 20 cm and analyzed by the combustion method using a C-N analyzer and measuring oceanographic parameters at the research location. The results showed that TOC in the Bakau Kecil River was higher (79 mg/L) compared to TOC in the Bakau Besar River (66.36 mg/L). This is based on the finding of the highest TOC in the Bakau Kecil River mangrove sediment compared to Bakau Besar, with values ​​of 840.14 tons C/ha and 698.86 tons C/ha, respectively. However, regression analysis showed a negative relationship between TOC in mangrove sediment and TOC in waters. If TOC in the river increases, then TOC in sediment tends to decrease. In addition, oceanographic parameters that affect TOC are tides. When TOC rises, TOC is more significant than when TOC recedes.

Abstract

Adolescent resilience to premarital sexual behavior refers to the ability of individuals (adolescents) to face and overcome the pressure of premarital sexual behavior in everyday life in a healthy and productive way, namely the ability to adapt to situations by providing responses to improve themselves. Adolescents' permissive attitude towards premarital sexual behavior is associated with low levels of reproductive health knowledge, higher exposure to pornographic media, strong negative group influences, weak parental roles, low religious beliefs and negative environmental influences. This study aims to analyze and explain the relationship between the characteristics of D3 nursing students in Indramayu Regency, internal and external factors, and adolescent resilience to premarital sexual behavior, and to identify the most dominant types of variables. This type of research is an explanatory study with a cross-sectional approach. The respondents were D3 nursing students at both universities in Indramayu Regency totaling 175 respondents. Data were collected using a survey instrument.

Abstract

The avocado (Persea americana), a recognized superfood and valuable horticultural commodity, exhibits significant morphological diversity due to long-term adaptation to various habitats, enhancing biodiversity. This study analyzed the diversity and genetic relationships of cultivated avocados in Gorontalo Regency. Using the Descriptors for Avocado (Persea spp.), 25 qualitative morphological traits were characterized, and a phenetic analysis of 17 accessions was conducted using UPGMA with Jaccard’s Coefficient. Accessions were collected from six villages across four sub-districts: Dulamayo Barat, Dumati, Hepuhulawa, Kayubulan, Kayumerah, and Tridarma. Results revealed substantial diversity in traits such as tree shape, and the morphology of stems, leaves, fruits, and seeds. Phenetic analysis grouped the accessions into two clades: Clade A, comprising 15 accessions in two clusters (similarity index: 64.7-29.0%), and Clade B, containing two accessions in one cluster (similarity index: 64.7%). Clades A and B exhibited a distant relationship, with a similarity index of 23.6%. Conserving the diverse avocado germplasm is essential for safeguarding genetic resources and supporting breeding programs to develop superior varieties in Gorontalo

Abstract

Low student learning outcomes are influenced by the use of new learning models and media that are still not ideal for science and the science learning process. Given that these challenges require the development and evaluation of learning media that aim to improve the educational achievements of children in grade four, this study aims to do so. The maker of smart applications based on PBL (Problem Based Learning) content about the Form of Matter and Its Changes is the learning media that is developed. Research and development, or RnD, is the process used, with the ADDIE model as the development framework. Participants in this study numbered 27 people from grade IV of SD Negeri 1 Brobot. Both pre- and post-test methods, as well as non-test methods such as observation, interviews, questionnaires, and documentation, were used in the data collection process. The media validator reached a very feasible level of 93.3% and the material validator 87%. A significant difference (Sig. 0.00 <0.05) was shown by the t-test between the pretest and posttest data. The N-gain test shows moderate requirements, with a small scales value of 0.61 and a large scales value of 0.64. Based on these findings, it is reasonable to conclude that the developer of PBL-based application learning media has created practical and effective substance-based content to be used in improving the educational outcomes of fourth grade students of SD Negeri 1 Brobot.
