Abstract

This study aims to determine the effectiveness of LC 5E learning models in improving skills and mastery of concepts conclude on chemical equilibrium material. The population in this study were all students of class XI Science SMAN I Natar Year 2012-2013 semester with classes XI IPA 4 and XI IPA 5 as a sample. This study uses a quasi experimental non equivalent control group design. effectiveness measured studying LC 5E n-Gain increased significantly. The results showed a mean value n-Gain skills classes concluded for the control and experimental respectively 0.35 and 0.71. While the average value of n-Gain mastery of concepts for the control and experimental classes, respectively were 0.31 and 0.41. Based on hypothesis testing, concluded that class with LC 5E learning through skills and mastery of concepts infer higher than conventional classroom learning. This suggests that the LC 5E learning models is more effective in improving skills and mastery of concepts students conclude on  chemical equilibrium material. Penelitian ini bertujuan untuk mengetahui efektivitas model pembelajaran LC 5E dalam meningkatkan keterampilan menyimpulkan dan penguasaan konsep pada materi kesetimbangan kimia.  Populasi dalam penelitian ini adalah seluruh siswa kelas XI IPA SMA Negeri I Natar semester ganjil Tahun 2012-2013 dengan kelas XI IPA 4 dan XI IPA 5 sebagai sampel. Penelitian ini menggunakan metode  kuasi eksperimen dengan Non equivalent control group design. Efektivitas model penbelajaran LC 5E diukur berdasarkan peningkatan n-Gain yang signifikan. Hasil penelitian menunjukkan rerata nilai n-Gain keterampilan menyimpulkan untuk kelas kontrol dan eksperimen masing-masing adalah 0,35 dan 0,71. Sedangkan  rerata nilai  n-Gain  penguasaan konsep untuk kelas kontrol dan eksperimen masing-masing adalah 0,31 dan 0,41. Berdasarkan pengujian hipotesis, disimpulkan bahwa kelas dengan pembelajaran melalui LC 5E  memiliki keterampilan menyimpulkan dan penguasaan konsep yang lebih tinggi dibandingkan kelas dengan pembelajaran konvensional.   Hal ini menunjukkan bahwa model pembelajaran LC 5E  lebih efektif dalam meningkatkan keterampilan menyimpulkan dan penguasaan konsep siswa pada materi kesetimbangan kimia.Kata kunci : keterampilan menyimpulkan, model learning cycle 5E, penguasaan konsep.

Abstract

The purpose of this study was to look at the characteristics and performance of male volleyball athletes produced by the Ujung Gading Club, West Pasaman Regency, such as the components of anaerobic endurance, agility, flexibility, arm muscle explosive power, leg muscle explosive power. This type of research is quantitative by using descriptive method. Instruments in this study consisted of Running-based Anaerobic Sprint Test (RAST), Agility T-Test, Bridge Up-Test, One Hand Medicine Ball Put and Vertical Jump Test. The sample in this study amounted to 18 people, the data analysis technique used was percentage. The results obtained between the components of the physical condition are: (1) The current anaerobic endurance is in the medium category with an average of 8.29, (2) the current agility is in the good category with an average of 13 seconds, (3) The flexibility that they have now is in the medium category with an average of 73 cm, (4) The explosive power of the arm muscles that they have now is in the medium category with an average of 5.27 meters, (5) The explosive power of their leg muscles now classified in the medium category with an average of 96 kg-m/second, (6) The current level of nutritional status belongs to the normal category with an average of 18.7, (7) the age level currently belongs to the category 15 - 17 years with an average of 16 years.

Abstract

This study examines the management of Indonesia’s Free Nutritious Meal (MBG) program at the classroom level, focusing on planning, organizing, implementation, and evaluation by second-grade teachers at SD Negeri 66, Bengkulu City. A qualitative descriptive design was employed, with data collected through observation, semi-structured interviews (n=8: 1 teacher, 1 principal, 6 students), and documentation over one semester. Data were analyzed using Miles and Huberman’s interactive model. Findings reveal that MBG management remains largely informal and operational. Planning focuses on improving student nutrition and reducing breakfast skipping through coordination with food providers and nutritionists. Organizing involves teachers and students with flexible, spontaneous task division. Implementation proceeds through teacher-student collaboration in food distribution, adapted to provider arrival schedules. Evaluation is conducted through simple observation of student enthusiasm and food quality, with feedback provided to providers for improvement. While the program supports students’ nutritional needs and demonstrates high student engagement, challenges persist in structured coordination, systematic documentation, and food quality control. This study contributes empirical evidence on frontline implementation of school feeding programs in Indonesia and recommends more systematic, documented management approaches at the school level.
