Abstract

This study aims to analyze the changes in the coastline in the coastal of Makassar city by using Digital Shoreline Analysis System (DSAS) method. The data used in this study was secondary data in the form of Landsat 5 and Landsat 8 digital satellite data which were acquired on 8 April 2019 and have been corrected radiometrically and geometrically obtained from the Lembaga Penerbangan dan Antariksa Nasional (LAPAN). The data was processed using ArcGIS 10.3 to obtain the overlay result. Shoreline Movement (NSM) and End Point Rate (EPR) methods used to calculate shoreline change calculations. Observation of shoreline changes takes 12 years using data in 2006, 2010, 2013, and 2018. Based on the results of the analysis with the method of Digital Shoreline Analysis System (DSAS) found that during 12 years the coast of Makassar experienced a change in coastline which is accretion due to reclamation that occurred in Tallo and Tamalate sub-districts.

Abstract

Abstrak-Telah dilakukan penelitian tentang porositas berdasarkan variasi ukuran butir batuan kawasan Karst Maros-Pangkep. Tujuan dari penelitian ini adalah untuk mengetahui gambaran nilai porositas batuan di Kawasan Karst Maros-Pangkep berdasarkan variasi ukuran butir dan menentukan pengaruh ukuran butir terhadap porositas batuan di Kawasan Karst Maros-Pangkep. Proses dimulai dari penentuan ukuran butir menggunakan lima macam saringan/ayakan, yaitu dengan nomor 50 mesh, 30 mesh, 16mesh, 10 mesh dan 4 mesh. Porositas ditentukan dengan menggunakan metode penimbangan. Setelah perhitungan ukuran rata-rata butir didapat selanjutnya dihubungkan dengan porositas dengan metode analisis regresi. Berdasarkan perhitungan statistik diperoleh persamaan regresi linear batuan Karst Maros-Pangkep, yaitu Y=15,00-2,82X dengan R2.=0,78. Diperoleh pengaruh ukuran butir terhadap porositas batuan kawasan karst Maros-Pangkep bernilai negatif artinya ukuran butir berbanding terbalik dengan porositas batuan di kawasan karst Maros-Pangkep. Semakin kecil ukuran butir maka porositas semakin besar dan semakin besar ukuran butir porositas semakin kecil. Kata kunci : Porositas, ukuran butir, batuan karst Pangkep, batuan karst Maros  Abstrak-Research on porosity has been carried out based on variations in grain size of the Maros-Pangkep Karst area. The purpose of this study was to describe the value of rock porosity in the Maros-Pangkep Karst Region based on grain size variations and to determine the effect of grain size on rock porosity in the Maros-Pangkep Karst Region. The process starts from determining the grain size using five kinds of sieves, namely with numbers 50 mesh, 30 mesh, 16mesh, 10 mesh and 4 mesh. Porosity is determined using the weighing method. After calculating the average grain size obtained, it is then connected to the porosity by using the regression analysis method. Based on statistical calculations obtained linear regression equation Maros-Pangkep karst rock, namely Y=15.00-2.82X with R2.=0.78. The effect of grain size on the rock porosity of the Maros-Pangkep karst area is negative, meaning that the grain size is inversely proportional to the porosity of the rocks in the Maros-Pangkep karst area. The smaller the grain size, the larger the porosity and the smaller the porosity. Keywords: porosity, grain size, Pangkep karst rock, Maros karst rock

Abstract

Abstrak. Ketahanan bahan pangan di Indonesia mulai memprihatinkan karena devisit akan ketersediaan beras akibat gagal panen saat terjadi bencana, apalagi jika ditambah dengan kesuburan tanah pertanian yang terganggu akibat adanya kandungan logam berat pada tanah pertanian. Salah satu sumbangan terbesar logam berat pada lahan pertanian dikarenakan penggunaan pestisida yang berlebihan. Keberadaan logam berat dapat diketahui dengan menelusuri sifat magnetik pada sedimen. Telah dilakukan penelitian di Kabupaten Sidrap Provinsi Sulawesi Selatan yang merupakan salah satu daerah swasembada beras di Indonesia, tepatnya pada 6 kecamatan dan 10 desa yaitu Kecamatan Kulo Desa mario, Kecamatan Baranti Desa Panreng, Kecamatan Pancarijang Desa Kadidi, Kecamatan Maritengngae Desa Kanie, Kecamatan Pitu Riawa Desa Lasiwala dan Kecamatan Watang Sidenreng Desa Talawali, Desa Empagae, Desa Kanyuara, Desa Aka-akae, Desa Damai. Pengambilan sampel dan analisis Suseptibilitas magnetik tanah dilakukan pada lapisan atas sebagai parameter kesuburan tanah pertanian, dengan tujuan untuk menganalisis nilai suseptibilitas magnetik pada residu tanah pertanian dan menganalisis sifat mineral magnetik pada residu tanah pertanian. Hasil analisis kualitatif menunjukan rentang nilai suseptibilitas magnetik frekuensi rendah 10,4 x 10-8 m3/kg sampai 71,5 x 10-8m3/kg. Hasil nilai χFD (%) yang diperoleh berada pada rentang 1,26% - 3,42%, Lahan dengan nilai χFD (%) kurang dari 2% mengindikasikan bahwa sampel tanah tersebut mengandung bulir multi domain (MD) dan masih memiliki kesuburan tanah yang baik untuk bercocok tanam, sedangakan  tanah dengan nilai χFD (%) 2-10% mengindikasikan bahwa sampel tanah tersebut memiliki domain superparamagnetik (SP) dan mengandung bulir stable single domain (SSD), sehingga telah mengalami penurunan kesuburan tanah untuk bercocok tanam.Kata Kunci: Tanah pertanian, Residu, Suseptibilitas magnetik

Abstract

This research was conducted with the objective of assessing the effectiveness of utilizing PhET media in order to increase the comprehension of physics concepts among eleventh-grade students at SMA Negeri 2 Makassar. This research design was a true experiment, specifically a pretest-posttest control group design. The population comprised all students of XI Science at SMA Negeri 2 Makassar with the total of three classes. The sampling method utilized was random sampling, and the process of collecting data entailed a test. The test consisted of a pretest conducted before the learning phase and a posttest administered after the completion of the learning activities. The indicators for assessing the comprehension of the concepts were based on Bloom's Taxonomy, specifically Translation, Interpretation, and Extrapolation. The comprehensive analysis of the data revealed that the students' comprehension of physics concepts was increased more effectively through the utilization of PhET simulation media. These findings suggest a significant positive effect of incorporating PhET simulation media in physics learning on student outcomes. The N gain score indicates an increase in students' comprehension of the material, demonstrating an increased ability to apply physics concepts following the implementation of PhET simulation media in the learning process. The implementation of PhET simulations in physics education yields positive impact in terms of increasing comprehension of physics concepts. Additionally, the utilization of PhET simulations facilitates the attainment of educational objectives by both teachers and students. Moreover, PhET simulations have the potential to streamline the learning process in classes that previously necessitated an abundance of materials and instruments for experimentation. In other terms, PhET serves as an effective learning medium.
