Abstract

This study aimed to find out the correlation between mathematics and basic physics ability of Natural Science Education Program students. This study was a correlational study that describes the extent to which two or more quantitative variables are interrelated. The study involved 38 students of the Natural Science Education Program, the Faculty of Science and Education, University of West Sulawesi, who programmed compulsory courses in basic physics and mathematics for the odd semester of the academic year 2023/2024. The results of the study were obtained from the physics ability test and the mathematics ability test, which was then, analyzed using the Spearman correlation test. Before the correlations test, the results were tested for normality first using the Shapiro Wilk test. As for the results of the study, the correlation between the mathematics abilities and the basic physics abilities of the students was rs = 0.7675 which is in the category of strong correlations and positive direction. This suggests that when students' mathematics abilities are high then students' basic physics abilities will be high anyway, just as when students’ mathematics abilities are low then students’ basic physics abilities will be low too.

Abstract

This research was motivated by students low interest and learning outcomes in science learning. The science learning process cannot fully meet students' needs and interests, causing low student learning outcomes. Teaching using the Teaching at The Right Level (TaRL) approach integrated with Social Emotional Learning (SEL) with the Problem Based Learning (PBL) model can facilitate various student learning characteristics and interests. The research aimed to determine the increase in learning interest and learning outcomes in science lessons on Elements, Compounds and Mixtures. This research used Classroom Action Research which was carried out in two cycles with each cycle containing four stages, namely planning, implementation, observation, then ending with reflection. Learning interest data was obtained through a learning interest questionnaire, while learning outcome data was obtained from written tests which were then analyzed quantitatively and qualitatively. The results showed that the average percentage of students' interest in learning before the action was 73.85% (fair) then increased to 79.97% (very high) after the action was given. In learning outcomes, an increase was obtained with an average score of 71.87 with learning completeness of 77.42% in cycle I and 82.19 in cycle II with learning completeness of 90.32%. Therefore, the SEL integrated TaRL approach with the PBL model can increase student interest and learning outcomes.

Abstract

This study highlights the crucial role of communication in managing hydrometeorological disasters in Jakarta, especially in addressing the impacts of climate change such as floods and heat waves. Effective communication, before, during, and after a disaster, has proven vital in reducing disaster risks and impacts. Data from BMKG and BPBD DKI Jakarta indicate that the increase in extreme rainfall and the poor city drainage system exacerbate flood events, while heat waves require specific communication strategies to protect the public from health risks. This study employs a literature review method, collecting data from various scientific literature to develop a comprehensive disaster management concept. The results show that mitigation, preparedness, response, and recovery approaches supported by targeted and inclusive communication can enhance community resilience. Initiatives such as socialization, preparedness simulations, and the use of social media are effective in disseminating information and improving community preparedness. BPBD DKI Jakarta's commitment to collaborating with various parties and utilizing the latest information technology underscores the importance of communication in modern disaster management. These efforts aim not only for short-term mitigation but also to build a more resilient community in facing future climate change challenges.

Abstract

A city will experience development over time because of growth population, economic, social, and culture activities, also interaction between cities. Yogyakarta also has undergone changes and developments that can be seen from road network, settlements, and green open spaces. This research aimed to study changes of Yogyakarta city from 1925-2020 based on road network, settlements, and green open spaces. Study used Yogyakarta’s old map from 1925, 1933, and 1946, map of Indonesia’s topography 2000, and RTRW 2020 maps. Analysis was done using overlay technique that result in changes from road network, settlements, and green open spaces also spatial structure that occurred during that period with GIS software. The result showed that Yogyakarta development was influence by the distribution of road network and existence of community activities centers. Spatial structure of Yogyakarta has not shown significant changes, it is still in the form of monocentric city with multi-nodal category. The development of this city shows that Yogyakarta already has a disaster-safe city planning.

Abstract

In the last three years, the production of melon has decreased. The decline in melon production was caused by the limited availability of superior seed varieties. Therefore, increasing production by developing superior varieties with high yields is necessary. Characterization is the first step in breeding plants. The research objective was to determine the characteristics of 21 melon genotypes. The research was conducted from January to March 2024. The research was conducted in Lubuk Saung Village, North Bengkulu Regency, Bengkulu Province. The experiment used a randomized complete block design on one factor with three replications. The factors used were 21 melon genotypes. The results showed that cluster analysis with a similarity of 33.33 produced five groups of melons, and G15 was the most different genotype among the other genotypes. Medium leaf size and medium green leaf color are the most dominant sizes and colors. The length of the leaf lobes in the medium category and the development of the leaf lobes in the weak category are the most dominant. The round shape of the fruit is the most common form of fruit. The skin color of the fruit before it is ripe is most green, and the color of the flesh when it is ripe is most white. Fruit without grooves is the most dominant, and surface wrinkles in the fragile fruit are the most dominant. Based on the characterization results, the next stage is selecting new superior varieties according to the desired characteristics.

Abstract

On December 17th 2022 there was hail in the Jakarta area. This phenomenon is unique and rarely occurs in the Equator region. This research was carried out by analyzing the profile of the convective clouds that produce hail using weather radar data. Data analysis was carried out by looking at factors from global, regional and local atmospheric conditions that caused the convective system to occur in Jakarta on that date. Then analyze the convective cloud structure that causes hail and estimate the probability of hail events based on ZHAIL products from weather radar. The hail that occurred in Jakarta was caused by convective clouds which occurred due to fairly unstable atmospheric conditions and was supported by weather factors on a global and regional scale. This results in the formation of cumulonimbus clouds with a strong updraft mechanism, characterized by the presence of a weak echo region (WER) and overhang echo (OE) during the cloud growth phase. Then, in the mature phase, the ice particles contained in the cumulonimbus cloud are quite large as indicated by the three body scatter spike (TBSS) pattern. The ZHAIL product shows that there is a chance of hail that is detected since the growth phase of the convective cloud and this condition consistently persists until just before the convective cloud produces hail. When hail occurs, the probability value of the hail event based on the ZHAIL product in this case study actually decreases and disappears in the radar image at a later time.
