Abstract

Permasalahan dalam penelitian ini yaitu rendahnya hasil belajar siswa pada pembelajaran IPA di kelas IV SDN 15 Ampana Kota. Penelitian ini bertujuan untuk meningkatkan hasil belajar siswa pada pembelajaran IPA melalui pembelajaran interaktif. Penelitian ini dilakukan pada siswa Kelas IV SD Negeri 15 Ampana, dengan jumlah siswa 32 orang. Untuk hasil belajarnya terjadi peningkatan seiring dengan diterapkannya tindakan pembelajaran melalui pembelajrn interaktif dari siklus I ke siklus II. Hasil belajar siklus I ketuntasan belajar klasikal yakni 75,00 % dengan jumlah yang tuntas sebanyak 22 orang siswa dan yang belum tuntas 10 orang siswa, aktivitas siswa 78,75% dan aktivitas guru 81,25%.  Pada siklus II ketuntasan belajar klasikal sebanyak  87,50 %  dengan rincian 28 orang siswa tuntas dan 4 orang siswa yang masih belum tuntas, aktivitas siswa 82,50% dan aktivitas guru 93,37%. Berdasarkan hasil tersebut menunjukan bahwa dengan pembelajaran interaktif dapat meningkatkan hasil belajar siswa pada materi penggolongan hewan berdasarkan jenis makanannya.

Abstract

Scleractinian coral such as Lobophyllia corymbosa that reproduce by external fertilization have an extended planktonic phase in their life cycle during which they "drift" in the water column. This life cycle phase is an advantage in itself because it increases the capacity of propagules to disperse far from their place of origin. In this hydrodynamic model study, secondary data on bathymetry and tides for the western monsoon period (represented by November 2017) were input into the Surface Water Modelling System SMS 8.1 to simulate the surface current circulation model. In running this program there are 2 important stages, namely GFGEN (Geometry File Generation) and RMA2 (Resources Management Associates-2). The simulation of surface current direction during the west monsoon, which is the reproductive period of L. corymbosa in Indonesia, shows the complexity and distraction of current vectors that occur in the coastal waters around Sulawesi Island. The model results indicate the possibility of spatial and temporal biological networks forming in waters around Sulawesi. The current patterns forming in Sulawesi waters during the west monsoon tend to circulate from north to south due to the higher volume of water mass originating from the Pacific Ocean flowing to the southern part of Sulawesi which is also the entry point for the Indonesian Throughflow (ITF). The larval dispersion model scenario produced for each location (Manado, Toli-Toli, Palu, Mamuju, Spermonde, Sinjai, Wakatobi, and Luwuk Banggai) tended to follow the water movement patterns, with most propagules leaving the location where they were spawned.

Abstract

Graphical Abstract   Highlight Research  Integrated DNA barcoding and morphological variations can improve the identification of grouper species. DNA barcoding confirms the morphological identification of Plectropomus (98-100% similar). High intraspecies genetic diversity revealed within Plectropomus in Makassar Strait. Potential cryptic species identified within Plectropomus based on genetic analysis.     Abstract  The high economic value of groupers has made them a popular choice in both local and international markets. However, identifying grouper species is also challenging due to complex morphological variations especially in the juvenile phase. An integrative approach combining DNA barcoding and morphometric analysis was applied to improve species identification accuracy and provide additional information on grouper stocks. This research aims to gain a deeper understanding of the morphological and genetic diversity of groupers caught in the juvenile phase from the Makassar Strait. Samples of the genus Plectropomus (n=6) collected from a fish landing site in Pangkajene Kepulauan Regency were identified based on morphology and using molecular methods (DNA barcoding). Phylogenetic and haplotype network analyses were performed. For all specimens the morphometric-meristic and molecular analyses were consistent (98-100% similarity) to known P. leopardus and P. oligacanthus accessions from GenBank. However, phylogenetic analysis: P. leopardus clustered into two distinct lower-level clades, and notably, two P. areolatus (Taiwan) resolved within the P. leopardus clade, while two P. laevis (Philippines) the resolved within the P. oligacanthus clade. Haplotype network showed high intraspecific genetic diversity, with P. leopardus forming four distinct haplotype groups and P. oligacanthus forming two groups. These findings collectively indicate that misidentification may be common and highlight the urgent need for further investigation into geographic barriers to gene flow and the potential existence of cryptic species or subspecies within Plectropomus. This study is expected to provide critical support for sustainable fisheries management and the conservation of marine biodiversity in the Makassar Strait.

Abstract

This study aims to determine the distribution and relationship between the concentration of cadmium metal (Cd) and total organic matter (TOM) in sediments in the Tallo estuary, Makassar City. The study collected sediment samples from 12 points, distance of 500m between points sampling. Furthermore, 12 sediment samples were analyzed for Cd and TOM concentrations in the laboratory. The results of measurements of Cd metal in sediments showed concentrations ranging from 0.001 - 0.037 mg/kg. The concentration of Cd metal found was still in the low category. While the concentration of TOM in sediment ranges from 6.7 -30.3%, indicating a low concentration. The distribution of Cd and TOM showed that the farther from the estuary, the lower the concentration. Based on the results of the regression test, the relationship between Cd and TOM concentrations was 80.1%. This shows that the accumulation of Cd metal in Tallo River sediments is strongly influenced by the concentration of organic matter.
