Abstract

Dynamic development in Indonesia's Urban Areas is influenced by population growth, economy, and environmental dynamics. By mid-2023, Indonesia's population will reach 278,696.2 million, ranking fourth as the largest population in the world. Unbridled urban growth has resulted in urban restructuring, agricultural land transformation, and a decrease in the area of green open space. This leads to a decrease in air quality, an increase in surface temperature, as well as changes in land cover patterns. A similar pattern is seen in Makassar City, where a shortage of green open space (less than 30%) and land-to-building changes have increased the city's surface temperature. This study aims to analyze the distribution of built-up land, land surface temperature (LST) and the relationship of land change built in Makassar City from 2014 and 2023 using Landsat Imagery. Analysis using Landsat Imagery and Normalized Defference Built-up Index algorithm shows significant growth of built-up land in accordance with the development plan of Makassar City until 2026. The surface temperature classification indicates a significant increase from 2014 to 2023, which is associated with built-up land growth. The results of simple linear regression showed a positive correlation between built-up land area and surface temperature, with R Square reaching 34.7% in 2014 and 38.9% in 2023. These findings reflect the impact of development on Land Surface Temperature (LST) and emphasize the urgency of built-up land management to reduce the impact of heat in cities.

Abstract

Gerhana matahari cincin merupakan fenomena alam langka yang terjadi secara periodik, sehingga moment seperti ini tidak akan dapat dinikmati sewaktu-waktu. Saat terjadi GMC posisi matahari, bulan dan bumi berada pada garis lurus, dimana posisi bulan berada diantara matahari dan bumi. Dalam pengamatan GMC tersebut LAPAN Pasuruan memasang beberapa teleskop portabel dan merekam data radiasi matahari menggunakan alat Automatic Weather Station (AWS). Pengambilan data radiasi matahari untuk proses analisa pada pukul : 11.00 wib. – 14.30 wib. Ketika memasuki fase awal GMC, saat GMC dan akhir GMC, pada satu hari sebelum, saat dan setelah GMC dalam kondisi tanggal : 25 Desember 2019 (min : 32 w/m2, max : 909 w/m2 , jml : 24.685 w/m2) tanggal 26 Desember 2019 (min : 218 w/m2, max : 608 w/m2, jml : 15.419 w/m2) tanggal 27 Desember 2019 (min : 50 w/m2, max : 955 w/m2, jml : 23.592 w/m2) dengan nilai prosentase = (( jml/∑jml)x100%) maka didapat nilai prosentase pada (tgl 25 = 38,75%, tgl 26 = 24,21%, tgl 27 = 37,04%) hasil analisa menyimpulkan dampak dari fenomena GMC terhadap perilaku data radiasi matahari mengalami perubahan sebagai berikut : nilai minimal mengalami kenaikan dari biasa dibandingkan data jam yang sama pada satu hari pra dan pasca GMC jumlah radiasi tanggal 26 Desember 2019 mengalami penurunan dibandingkan data pada tanggal 25 atau 27 Desember 2019.

Abstract

This study aims to develop multiple representation-based electronic modules with the help of mobile physics learning on momentum and impulse material in class X MIPA. The research wants to test the effectiveness of e-modules based on their validity in increasing students' understanding of concepts and learning interest. The research method used is quantitative with the 4D model (Define, Design, Develop, and Disseminate). The subjects of this research were students in class X MIPA 2 and X MIPA 4 SMA Negeri 1 Kalasan. The research design used was one group pretest-posttest research design. There are two instruments used, namely test and non-test instruments, as well as data analysis techniques using Microsoft Excel. The results of the study show that the use of multiple representation e-modules assisted by physics learning cars is feasible to be used as teaching materials. In addition, the results of differences in pretest and posttest scores and interest in learning in the modeling class were 86% and in the implementation class were 88% indicating an increase in learning interest received by students.
