Abstract

Smartphones are a physical learning medium that can support students to experiment with measurement devices. One of the smartphone apps that can be used is phyphox. The study aims to find out collision analysis lends several types of fall fields that include soil, ceramic floor areas and board fields so that it will generate data on the height, time, and energy generated when objects hit the surface. The method used is an experiment with a collision testing comparison approach with different drop fields using phyphox and stopwatch applications. The results of three experiments in the energy board field that apples produce are larger than ceramic and soil floor fields. While the results of experiments using stopwatches showed that the energy produced has a slightly greater value than using phyphox. Phyphox application can be used for practicum independently.

Abstract

Hydrological droughts in Bantul Regency significantly reduce crop productivity to an average of 59.97 kw/ha, thereby affecting farmers' income due to land conversion and water scarcity. This study evaluates the economic implications of supplementary irrigation in high, moderate, and low drought-prone zones. Farmers in low (Sabdodadi) and moderate (Guwosari) drought-prone areas can cultivate rice twice a year, whereas those in high drought-prone areas (Wukirsari) can do so only once. The methods employed include literature review, field survey, field data collection, and data analysis using RIA (Residual Imputation Approach) and ArcGIS 10.8. Cash costs for the third planting season in Sabdodadi, Guwosari, and Wukirsari amounted to Rp 11,590,451, Rp 11,698,165, and Rp 10,671,432 per hectare, respectively. Non-cash costs were Rp 2,600,260, Rp 3,331,483, and Rp 4,229,162 per hectare. Total production costs fluctuated, particularly in Sabdodadi, totaling Rp 14,190,711 per hectare. Sabdodadi exhibited the highest income at Rp 15,518,964 per hectare, while Guwosari and Wukirsari reached Rp 15,778,358 and Rp 14,778,346 per hectare. Supplementary irrigation significantly enhances the economic value of food crops, ranging from 20% to 29.15%, with Wukirsari making the highest contribution. The strategy of implementing flexible water tariffs and developing irrigation infrastructure can be applied to promote economic growth in drought-prone areas. Empowering farmers through economic incentives and access to adequate irrigation water is expected to create conditions conducive to sustainable agriculture.

Abstract

Abstrak Ilmu Pengetahuan Alam tidak hanya membahas tentang materi akan tetapi juga  tentang praktik atau pengalaman secara langsung. Peserta didik seharusnya diajak melaksanakan praktik secara riil, konkrit, sesuai dengan teori yang sedang dipelajari (Dalam konteks IPA SD yaitu tentang keadaan lingkungan sekitar, atau yang ada di kehidupan sehari-hari). Permasalahan yang ada di lapangan, pada kenyataanya, sebagian guru  hanya mengajarkan teori yang ada di buku dan hanya menerapkan pembalajaran di dalam ruang kelas. Hal tersebut dipicu karena tidak adanya fasilitas laboratorium yang memadai di sekolah, serta minimnya motivasi untuk membuat inovasi pembelajaran. Penelitian ini menggunakan metode penelitian kualitatif dengan pendekatan phenomenology. Berdasarkan hasil penelitian, sebenarnya solusi dari permasalahan ini sangat dekat dengan bapak/ibu guru, yaitu  lingkungan sekitar sekolah dengan berbagai objek dan fenomenanya. Adanya lingkungan sekolah ini baik halaman, kebun dan  lapangan sekolah ini dapat menjadi wahana yang sangat tepat sebagai alternatif laboratorium pembelajaran, atau dengan istilah lain yaitu sebagai laboratorium berbasis lingkungan.
