Abstract

This study examines the process problem-solving method of Arabic lessons at Gontor for the girl's first campus, which is suitable for his students to get good results and according to expectations.The Problem-Solving method provides understanding by stimulating students to pay attention, examine, and think about a problem to analyze the problem further to solve the problem. Analyzing is the concept of combining thoughts with motor activities to solve problems. Sources of data used in this study are primary and secondary data sources. This study uses data collection techniques with interview methods, observation methods, and documentation methods. The technique of guaranteeing the validity of the data in this study is the triangulation of sources and data collection techniques. Qualitative data analysis in this study is descriptive data consisting of three activities simultaneously. Namely data reduction, data presentation, and conclusion. Based on the results of research and analysis, it can be found that the use of problem-solving methods in Arabic lessons in one intensive 2021-2022 is in the problem-solving method, the teacher uses steps such as problem clarification, expression of opinion, evaluation, and implementation. Then, the supporting factors for learning Arabic using problem-solving methods are knowledge, understanding, and application, while the inhibiting factors for learning Arabic using problem-solving methods are time, learning difficulties, and use.

Abstract

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.

Abstract

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.

Abstract

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

Abstract

Earthquake’s phenomena are critical for understanding Earth's interior, tectonic processes, and disaster preparedness. Because of indonesia location in the Pacific Ring of Fire, it’s suffering from regular seismic activities which result in huge annual losses. This study investigates the earthquake data from 1992 to 2024 by applying clustering techniques such as K-means and geodata visualization. By integrating physics, geospatial analysis, and machine learning, the study processes earthquake data to calculate energy release and analyze spatial-temporal patterns. Principal Component Analysis (PCA) is applied to reduce data dimensionality, while K-Means clustering identifies seismic patterns based on magnitude, depth, and energy. Visual tools, including correlation heatmaps and spatial maps, are used to present findings that support earthquake risk management in Indonesia.The results reveal temporal patterns in earthquake activity, with peaks observed in 2004–2007, associated with significant seismic energy release. Spatial analysis highlights high energy concentrations in megathrust zones. PCA and K-Means clustering identify three distinct clusters with varying correlations between seismic and atmospheric variables, indicating the influence of thermal and tectonic factors. These insights contribute to seismic hazard mapping, risk reduction strategies, and the improvement of earthquake prediction models. Future research should extend datasets and refine machine learning techniques to achieve more accurate predictions.
