Isotonic drinks can replace body fluids quickly because they contain electrolytes needed by the body. This study uses young coconut water as the primary raw material with the addition of pineapple juice to improve the taste and nutritional value of isotonic drinks. This study aimed to determine the characteristics of coconut water isotonic drinks by adding pineapple juice with different formulations and sweeteners. This study used a factorial block randomized experimental design consisting of two factors; the concentration of fruit juice and variations in the type of sweetener. The total of coconut water and pineapple juice was 20 mL with the ratio of coconut water: pineapple juice (14:6); (10:10); and (6:14). The sweeteners used were sucrose (6 g), honey (0.4 g), and stevia (0.03 g). The results showed that the different formulations of coconut-pineapple water affected the antioxidant activity, total dissolved solids, and potassium content of the coconut-pineapple water isotonic drink. Different sweeteners affected the antioxidant activity and total soluble solids of pineapple coconut water isotonic drink. The interaction of formulation and type of sweetener affected antioxidant activity and potassium content. The coconut-pineapple water isotonic drink in this study has met the SNI for isotonic drinks in pH values, sodium content, and total soluble solids for sucrose and stevia sweeteners, but the potassium content still exceeds the standards set by the SNI.

The production of coffee in Indonesia, particularly in Lampung, plays a crucial role in both the local and national coffee sectors. Weather plays a crucial role in the development of coffee trees. Nonetheless, the coffee production is frequently hindered by unpredictable weather conditions. This can be foreseen through the use of scientific forecasting. Blending agriculture and science can maximize coffee production and effective resource utilization. This study creates a predictive model for coffee production by combining machine learning methods with the NASA POWER dataset. Data from NASA POWER is used to acquire information on various weather factors that impact the growth of coffee trees, including solar radiation, temperature, humidity, pressure, soil wetness, and wind speed. Additionally, information on coffee production is sourced from BPS-Statistics Indonesia. The Random Forest algorithm is used to model the connection between variables. The study findings demonstrate that combining machine learning with remote sensing can offer an effective model. Assessment of the R2, RMSE, and MSE figures shows satisfactory results, though not flawless. This happens due to external factors beyond the weather that influence coffee cultivation. The combination of machine learning and remote sensing is incorporated into a website. This model has the potential to be transformed into an app that offers precise details on coffee cultivation in Lampung. This research highlights how remote sensing data can offer insights into predicting sustainable agriculture outcomes.

Penelitian ini bertujuan untuk mengidentifikasi reactive oxygen species (ROS) yang dihasilkan oleh plasma dielectric barrier discharge (DBD) pada konfigurasi rangkaian single dan double menggunakan Optical Emission Spectroscopy (OES). Variasi reaktor DBD digunakan untuk mengevaluasi spektrum emisi plasma. Hasil menunjukkan bahwa intensitas spektrum emisi pada rangkaian double secara umum lebih tinggi dibandingkan dengan Single. Produksi radikal OH dan O pada konfigurasi double lebih stabil, sementara emisi spektrum N₂ menunjukkan intensitas yang lebih besar dibandingkan dengan single. Stabilitas ini diuji lebih lanjut pada sampel dengan pH basa, yang menunjukkan penurunan pH menuju netral. Pengukuran suhu menunjukkan kestabilan selama proses berlangsung, menjadikan konfigurasi double DBD efektif untuk penelitian yang membutuhkan kestabilan suhu larutan. Hasil ini mengindikasikan bahwa rangkaian double dapat meningkatkan efisiensi produksi ROS dalam aplikasi plasma. Kata Kunci: Plasma DBD, spesies oksigen reaktif, spektroskopi optik emisi, rangkaian tunggal dan ganda Abstract This study aims to identify reactive oxygen species (ROS) generated by dielectric barrier discharge (DBD) plasma in single and double configurations using Optical Emission Spectroscopy (OES). Variations in DBD reactors were employed to evaluate the plasma emission spectra. The results showed that the emission intensity in the double configuration was generally higher than in the single configuration. The production of OH and O radicals in the double configuration was more stable, while the N₂ emission spectrum exhibited higher intensity compared to the single configuration. This stability was further tested on a sample with alkaline pH, which showed a decrease in pH toward neutrality. Temperature measurements demonstrated stability throughout the process, making the double DBD configuration effective for studies requiring solution temperature stability. These findings indicate that the double configuration can enhance ROS production efficiency in plasma applications. Keywords: DBD plasma, reactive oxygen species, optical emission spectroscopy, single and double configurations

Laboratorium merupakan jantung dari pembelajaran IPA. Pembelajaran IPA yang menyeluruh wajib mengaktifkan penggunaan laboratorium. Namun, pengelolaan Laboratorium IPA khususnya di SMP Kabupaten Lampung Timur belum terstandarisasi dengan baik. Standarisasi dalam bentuk SOP merupakan hal penting untuk panduan pelaksanaan praktikum, pengelolaan alat dan bahan hingga masalah keselamatan. Merujuk dari fenomena tersebut, tujuan pelatihan ini untuk meningkatkan kemampuan guru IPA dalam penyusunan SOP berstandar internasional ISO 9001:2015. Peserta pelatihan mencakup guru-guru IPA SMP di Kabupaten Lampung Timur. Pelatihan menerapkan tiga metode yaitu pemberian materi, praktik penyusunan SOP, dan presentasi dokumen. Evaluasi kegiatan untuk mengukur pemahaman peserta diukur dengan ujian pre-test dan post-test dan diperoleh kenaikan rata-rata sebesar 43,22%. Selain itu, pelatihan ini berhasil menghasilkan enam dokumen SOP yang telah berstandar ISO 9001:2015. Hasil ini menjadi indikator tercapainya tujuan pelatihan. Dokumen SOP berstandar ISO 9001:2015 yang telah disusun peserta siap diimplementasikan di sekolah masing-masing.

ABSTRACTMaterial physics is an important branch of science that studies the properties and applications of various materials from atomic level as the foundation for modern technological development. The importance of this field encouraged the implementation of a socialization activity aimed at improving students’ understanding of the basic concepts and applications of material physics. The activity was attended by 22 participants and consisted of three stages: an initial survey, socialization using the one group pretest–posttest design through interactive and contextual methods, and data evaluation. The average pretest score of 2.22 increased to 3.45 in the posttest, indicating an improvement based on the Likert scale. These results show that the socialization activity contributed positively to enhancing participants’ understanding and interest in the concepts and applications of material physics. The interactive approach used in the socialization proved effective in strengthening participants’ motivation and insight into this field.Keywords: Physics, material, educationABSTRAKFisika material merupakan cabang ilmu penting yang mempelajari sifat dan aplikasi berbagai material dari tingkat atomik sebagai dasar pengembangan teknologi modern.

Atmospheric physics is very useful in predicting rainfall, particularly for analyzing air saturation conditions as a prerequisite for condensation. This study aims to model rainfall prediction using thermodynamic parameters, namely relative humidity (RH) and dew point temperature difference (ΔT). These parameters were collected from BMKG Lampung meteorological data (2022–2024) and processed using the Magnus equation. ΔT is important as a sensitive indicator of air unsaturation. The data were statistically analyzed and modeled using a Gradient Boosting Classifier. The results obtained indicate a strong correlation between RH and ΔT and rainfall events (point-biserial correlation of 0.475). Furthermore, ΔT during rainfall is lower (average 2.87°C) and stable, indicating near-saturation conditions. During the evaluation stage, the model achieved 76% accuracy and 84% recall during rainfall. The model's good performance proves the effectiveness of physical parameters as predictive features. Finally, the model was implemented in a Flask-based web application for practical accessibility.
