Abstrak: Minat baca masyarakat yang rendah karena tingkat kebiasaan membaca membaca juga rendah, termasuk di PKBM Gempita. PKBM Gempita sudah memiliki Taman Bacaan Masyarakat (TBM). Namun, membaca belum menjadi kegiatan rutin literasi di PKBM ini sehingga kemampuan membaca warga belajar belum baik. Berdasarkan permasalahan tersebut, tujuan pelaksanaan PKM ini adalah melakukan pelatihan kegiatan membaca yang bermakna dengan menerapkan Teknik Sprites untuk meningkatkan kemampuan membaca warga belajar. Metode pelaksanaan dilakukan dengan tahap persiapan, pelatihan, penerapan teknologi, pendampingan, dan evaluasi kegiatan. Teknik Sprites terdiri atas lima langkah, yaitu meningkatkan minat dan motivasi, meningkatkan periferal, meningkatkan kecepatan gerakan mata, melakukan survei wacana, dan meningkatkan konsentrasi. Penerapan teknik tersebut telah dilakukan dalam pelatihan dengan hasil yang cukup baik, yaitu terjadi peningkatan kemampuan membaca peserta pelatihan berdasarkan hasil pretes dan postes. Kemampuan membaca peserta pascapelatihan adalah 19% pada kategori baik sekali, 54% pada kategori baik, dan 27% pada kategori sedang. Hal tersebut bisa terjadi karena beberapa faktor, satu di antaranya adalah kesadaran dalam latihan mandiri peserta di rumah belum maksimal.

hich enables devices to be interconnected through the internet to perform monitoring and data exchange in real time. In hydroponic cultivation, water quality stability is a crucial factor that affects plant growth. The main parameters that need to be monitored include water acidity level (pH), water temperature, and dissolved nutrient concentration measured using Total Dissolved Solids (TDS). However, water quality monitoring is still commonly conducted manually, making it less efficient and potentially causing delays in detecting changes in water conditions. This study aims to design an IoT-based water quality monitoring system for hydroponic cultivation using an ESP32 microcontroller integrated with pH, temperature, and TDS sensors. The collected data are sent to a server and displayed on a web dashboard in real time, equipped with automatic notification features.

Abstract:This study investigates the stress concentration factor in an infinite steel plate with a thickness of 1 cm, containing an elliptical hole, subjected to biaxial loading at infinity. The elliptical hole has semi-axes a=5.0 cma…
0 cma = 5.0 \, \text{cm}a = 5.0 cm (major axis) and b=2.5 cmb = 2.5 \, \text{cm}b = 2.5 cm (minor axis). The applied stresses at infinity are a tensile stress of σ1=100 kg/cm2\sigma_1 = 100 \, \text{kg/cm}^2= 100 kg/parallel to the major axis and a compressive stress of σ2=−100 kg/cm2\sigma_2 = -100 \, \text{kg/cm}^2= -100 kg/ perpendicular to the major axis. The material properties include Young's modulus E=2.1×106 kg/cm2E = 2.1 \times 10^6 \, \text{kg/cm}^2E = 2,1. kg/ and Poisson's ratioν=0.3\nu = 0.3 = 0.3. Using analytical solutions from classical elasticity theory, the maximum tangential stress at the edge of the ellipse is calculated as σmax=600 kg/cm2\sigma_{\text{max}} = 600 \, \text{kg/cm}^2= -600 kg/, yielding a stress concentration factor of kσ=σmax/σ=6k_\sigma = \sigma_{\text{max}} / \sigma = 6 = =6. Additionally, a finite element (FE) analysis based on the Salerno and Sahoni problem for a quarter section of the plate results in kσ=3.1125k_\sigma = 3.1125 = 3.1125 for a configuration with s/r=5s/r = 5s/r = 5, showing a discrepancy of 1.3% compared to the theoretical value of kσ=3.1k_\sigma = 3.1= 3.1 from Peterson's Stress Concentration Factors. The results demonstrate good agreement between the calculated model and theoretical predictions, validating the accuracy of the FE approach for stress concentration analysis in such configurations.

Learn." A hermeneutic-phenomenological study was conducted with five students in grades 4-5. Data were generated through in-depth conversations and participant observations during a four-week classroom mindfulness program and analyzed through phenomenological reduction and thematic synthesis. The research findings indicate that the unchanging essence, namely "a shift from an anxious mind to a calm mind that opens up space for learning," is expressed through four interrelated themes: perceived emotional calm, sustained attention, easier recall, and positive appreciation of quiet moments. The study concludes that mindfulness is not simply a technique, but a pedagogical way of life that begins with learning; integrating brief, mindful pauses can foster reflective, calm, and independent learners aligned with the Pancasila Student Profile.
