Abstract

Implementing geography learning using the blended learning model is challenging for most geography teachers because this subject is ‘hands-on’ and needs to be learned directly in a real environment using fieldwork. This study aimed to test the pedagogical effectiveness of the geographic-inquiry on virtual environment (GIVE) application in supporting fieldwork based on blended learning to improve students’ geographical thinking. This study used a quasi-experimental method involving 216 high school students from three schools. The paired sample t-test (Sig. 2-tailed 0.000) shows that GIVE has a pedagogical influence on students’ geographical thinking. GIVE also offers a big effect size (Cohen’s d=1.37). The technology and the right smartphone application can help develop a virtual environment close to a real one, so fieldwork and hands-on learning activities can be carried out in blended learning; this helps to increase the quality of geography learning.

Abstract

The Bale River Sub Basin is located in Tulungrejo Village, Gandusari District, Blitar Regency, on territory with undulating topography and at an elevation of 519 to 846 meters above sea level, with steep to extremely steep slopes. The majority of the Bale sub-watershed area's land use, notably forests, has been transformed into agricultural land or mixed gardens, where land conversion is carried out without or with conservation measures under adverse land cover conditions. Land use that does not comply with land conservation requirements exposes the Bale sub-watershed to erosion, and the Bale sub-watershed has steep slopes. As a result, this research aims to forecast the quantity of erosion in the Bale sub-watershed. This study employed a literature review and a field survey, with data collected in the form of primary and secondary sources. The MUSLE (Modified Universal Soil Loss Equation) approach was used for data analysis to estimate the amount of erosion in the research area. According to the findings of this study, the Bale sub-watershed has 18 land units, with land unit 4 having the highest erosion value of 647,99 tons per hectare per year. Land unit 4 has a Vq factor value of 2.322,76 m3, a K value of 0.50, an LS value of 1.7, and a CP value of 0.60 with residential land use and no conservation activities. Meanwhile, land unit 17 had the lowest erosion value of 1,09 tons per hectare per year. The Vq value for the land unit is 686,05 m3, the K value is 0.30, the LS value is 3.8, and the CP value is 0.02 using forest land and conservation methods such as bunds and reinforcing grass. Sub Daerah Aliran Sungai Bale berada di Desa Tulungrejo, Kecamatan Gandusari, Kabupaten Blitar yang memiliki lahan dengan topografi yang bergelombang dan berada pada ketinggian antara 519 – 846 mdpl dan didominasi dengan kelerengan yang curam hingga sangat curam. Penggunaan lahan di sebagian besar wilayah sub DAS Bale, yaitu berupa hutan telah banyak berubah menjadi lahan pertanian atau kebun campuran. Dimana alih fungsi lahan tersebut dilakukan tanpa atau dengan tindakan konservasi dan kondisi penutup lahan yang kurang baik. Pemanfaatan lahan yang tidak sesuai dengan ketentuan konservasi lahan akan berakibat pada kerentanan sub DAS Bale terhadap kejadian erosi, ditambah Sub DAS Bale memiliki kemiringan lereng yang curam. Dengan demikian, tujuan dari kajian ini adalah untuk menduga/prediksi besaran erosi di Sub DAS Bale. Metode yang digunakan dalam penelitian ini adalah studi literatur dan survei lapangan dengan data yang digunakan berupa data primer dan sekunder. Analisis data dilakukan dengan menggunakan metode MUSLE (Modified Universal Soil Loss Equation) untuk pendugaan besarnya erosi pada wilayah kajian. Hasil dari penelitian ini, terdapat 18 unit lahan di Sub DAS Bale dengan nilai erosi terbesar pada unit lahan 4 sebesar 647,99 ton/ha/tahun. Satuan unit lahan 4, memiliki nilai faktor Vq sebesar 2.322,76 m3, nilai K sebesar 0,50, nilai LS sebesar 1,7 dan nilai CP sebesar 0,60 dengan penggunaan lahan permukiman tanpa adanya upaya konservasi. Sementara itu, nilai erosi terkecil terdapat pada unit lahan 17 sebesar 1,09 ton/ha/tahun. Nilai Vq pada unit lahan tersebut sebesar 686,05 m3, nilai K sebesar 0,30, nilai LS sebesar 3,8, dan nilai CP sebesar 0,02 dengan penggunaan lahan hutan serta upaya konservasi berupa guludan dan rumput penguat.

Abstract

Total Suspended Solid (TSS) is defined as a collection of suspended matter and particles in water with a size of less than 2 microns. High concentrations of TSS are dangerous because they interfere with light penetration into the water. This disrupts the photosynthesis process and causes reduced oxygen levels in the waters. Conventional TSS monitoring in laboratory tests is considered less efficient regarding time, effort and cost. Therefore, remote sensing technology is a more efficient alternative solution for TSS monitoring in reservoirs. One type of imagery that can be used to monitor TSS in reservoirs is Landsat 8 satellite imagery. This article aims to determine the appropriate empirical algorithm in estimating TSS concentrations in the Gondang Lamongan Reservoir, to examine the spatial distribution of TSS in the Gondang Reservoir with a 3-year time span, namely 2016, 2019, and 2022, and to analyze changes in reservoir TSS conditions in recent years. research year. The method used in this research is descriptive quantitative with the application of the Syarif, Parwati and Guzman & Santaella algorithms. The results showed that the condition of TSS from year to year continued to increase. The concentration of TSS is getting worse, which is indicated by an increase in the amount of TSS at the edge of the reservoir, especially at inlet area. The results of the accuracy test show a coefficient of determination of 0.71 for the syarif algorithm which indicates that the syarif algorithm method is quite accurate in estimating the TSS in the Gondang reservoir. Total Suspended Solid (TSS) didefinisikan sebagai kumpulan dari materi dan partikel yang tersuspense di dalam air dengan ukuran mencapai kurang dari 2 mikrometer. Konsentrasi TSS yang tinggi bersifat membahayakan karena mengganggu panetrasi cahaya yang masuk ke dalam air. Hal ini berakibat pada terganggunya proses fotosintesis dan menyebabkan berkurangnya kadar oksigen di perairan. Pemantauan TSS secara konvensional melalui uji laboratorium secara masif dinilai kurang efisien baik dari segi waktu, tenaga dan biaya. Oleh karena itu, teknologi penginderaan jauh menjadi solusi alternatif yang lebih efisien untuk melakukan pemantauan TSS di waduk. Salah satu jenis citra yang dapat digunakan untuk memantau TSS di waduk adalah citra satelit Landsat 8. Artikel ini bertujuan untuk menentukan algoritma empiris yang sesuai dalam mengestimasi konsentrasi TSS di Waduk Gondang Lamongan, mengkaji distribusi spasial TSS di Waduk Gondang dengan rentang waktu 3 tahunan, yakni di tahun 2016, 2019, dan 2022, serta menganalisis perubahan kondisi TSS waduk di tahun-tahun penelitian. Metode yang digunakan pada penelitian ini adalah deskriptif kuantitatif dengan penerapan algoritma Syarif, Parwati dan Guzman & Santaella. Hasil penelitian menunjukkan bahwa kondisi TSS dari tahun ke tahun terus mengalami peningkatan. Konsentrasi TSS semakin memburuk yang ditandai dengan peningkatan jumlah TSS di bagian tepi waduk yang merupakan area inlet. Hasil uji akurasi menunjukkan nilai koefisien determinasi sebesar 0,71 untuk algoritma syarif dimana hal tersebut menandakan bahwa metode algoritma syarif cukup akurat dalam mengestimasi TSS di Waduk Gondang.

Abstract                                                             The quality of groundwater is naturally determined by water-bearing rock characteristics. However, the progression of civilian activities also negatively affects the groundwater quality. Therefore, this study aims to assess groundwater's physical, chemical, and biological characteristics in Indonesia's Universitas Negeri Malang (UM) campus area and evaluate its compliance with drinking water quality standards, particularly the Class A standard. A comparative descriptive strategy was utilized in the study by involving groundwater in the campus area of UM. The focus of the research is water quality in unconfined aquifers. Through purposive sampling, 12 wells were selected to ensure appropriate spatial dispersion. Water samples were collected in sample bottles and tested for physical, biological, and chemical properties. The Perum Jasa Tirta I Malang carried out these water quality tests. Water quality data were analyzed qualitatively, descriptively, and comparatively. This study concludes that (1) the groundwater on the UM campus generally meets the physical criteria for drinking water quality standards; (2) the chemical quality of the groundwater on the UM campus still satisfies the drinking water quality standards; and (3) biologically, the free groundwater on the UM campus fails to meet drinking water quality standards. The novelty of this research is that the biggest threat to the quality of free groundwater in the campus area is bacterial contamination from sanitation activities. Accordingly, it is recommended that groundwater is boiled before being utilized for drinking water purposes to neutralize the E. coli bacteria present in all well water samples.Keywords: Water Quality of Unconfined Aquifer; The Drinking Water; Quality Standard

Abstract

Total Suspended Solids (TSS) are defined as particles and materials suspended in water with sizes up to less than 2 µm. High TSS concentrations pose significant hazards by hindering light penetration, disrupting photosynthesis, and reducing oxygen levels in aquatic environments. Conventional TSS monitoring through laboratory tests is often inefficient regarding time, labor, and cost. Consequently, remote sensing technology provides a more efficient alternative for TSS monitoring in reservoirs. This study utilizes Landsat 8 satellite imagery to develop suitable empirical algorithms for estimating TSS concentrations in Gondang Reservoir, Lamongan. It aims to evaluate the spatial distribution of TSS over three years (2016, 2019, and 2022) and analyze changes in TSS conditions throughout these periods. The research employs a quantitative descriptive method, applying the Syarif, Parwati, and Guzman & Santaella algorithms. Results indicate a continuous increase in TSS concentrations annually, with the highest concentrations observed in the reservoir's inlet areas. Accuracy tests reveal a coefficient of determination (R²) of 0.71 for the Syarif algorithm, demonstrating its substantial accuracy in estimating TSS levels in Gondang Reservoir. This study underscores the worsening TSS conditions in the reservoir and highlights the effectiveness of remote sensing technology for environmental monitoring.
