Abstract

Ketersediaan air bersih menjadi permasalahan utama bagi masyarakat Kelurahan Wamponiki karena ketidaklancaran distribusi air oleh PDAM (Perusahaan Daerah Air Minum) Kabupaten Muna, yang hanya menyuplai air dua kali seminggu, bahkan terkadang hanya sekali dalam seminggu. Sebagai alternatif, masyarakat bergantung pada sumur gali, namun air yang dihasilkan seringkali bermasalah, seperti berwarna kuning, berbau, dan keruh, sehingga tidak memenuhi standar kualitas air bersih. Untuk mengatasi hal ini, Tim Pengabdian Masyarakat melakukan penyuluhan dan memperkenalkan penggunaan tabung filter air siap pakai sebagai solusi praktis dalam meningkatkan kualitas air sumur. Selain itu, dilakukan analisis laboratorium untuk memastikan keamanan air hasil penyaringan dengan membandingkannya terhadap baku mutu kualitas air bersih berdasarkan Peraturan Menteri Kesehatan (Permenkes) No. 32 Tahun 2017 dan Permenkes No. 2 Tahun 2023. Hasil analisis menunjukkan bahwa air yang telah melalui proses filtrasi masih belum memenuhi standar baku mutu yang ditetapkan, sehingga diperlukan upaya lebih lanjut untuk meningkatkan efektivitas teknologi penyaringan atau mencari solusi alternatif. Kegiatan pengabdian ini diharapkan dapat meningkatkan kesadaran masyarakat akan pentingnya air bersih serta mendorong tindakan lebih lanjut dari pihak terkait untuk menjamin akses air minum yang layak.

Abstract

The objective of this study was to evaluate the variations of twelve chemical elements (Ni, Fe, Co, Mg, Mn, Al, Si, Zn, Ti, P, Ca and Cr) in laterite soil profiles from Wantulasi area in South East Sulawesi Province of Indonesia. Eighty four (84) samples of three profiles (i.e. each profile consists of eight samples) had been used to study their variations in soil using the X-Ray Fluorescence (XRF). Results analysis of the chemical elements content in three profile using XRF indicated that there were good correlationsbetween the chemical elements in the soil profile with the significant correlations were found in Ni and Fe, Ni and Si, Ti and P, Fe and Al, and Co and Mn, respectively. On the other hand,the results of study showed that the variations of the chemical elements could be related to the enrichment and translocation of the elements in soil profile and also their possibilities to be related with a given chemical elements in soil profile. Therefore, we suggest that the observed patterns in chemical elements with a good correlation in laterite profile can be used as proxies to integrate the evaluation of the chemical and physical weathering process based on the elements characteristics in soil profiles.

Abstract

Geography learning about spatial patterns of villages and cities in high schools still faces obstacles in students' understanding of concepts due to teacher-centered learning. This study aims to determine the effect of problem-based learning (PBL) models with the help of Canva media on students' conceptual understanding. Quasi-experimental research was conducted at SMAN 10 Kendari on class XII IPS students. Class XII IPS.1 was designated as an experimental class that learned using problem-based models combined with Canva media, and class XII IPS.2 became a control class with conventional learning methods based on the same abilities. Research data were collected through a concept understanding test and then analyzed using parametric inferential statistical tests. The analysis using independent sample t test after get the normality and homogenity test. The results of the t-test showed a significance value of 0.000, with students in the experimental class having a higher increase in conceptual understanding than those in the control class. This finding shows that PBL utilizing Canva media has proven to be effective in helping students understand the subject matter in problem-oriented learning steps and media that attract students' attention. This study implies that the use of Canva digital media in PBL can be an effective strategy to improve students' conceptual understanding. Teachers are advised to use Canva digital learning media as a teaching aid, especially when implementing PBL, so that students can more easily understand the concepts being studied.
