Penerapan Metode Jigsaw Dalam Mengupayakan Pemahaman Konsep Siswa Kelas XII Pada Materi Sel Volta; Application of the Jigsaw Method in Strive to Understand Class XII Students' Concepts in Voltaic Cell Material
No full text AbstrakManusia diberikan Allah akal budi sehingga memperoleh pemahaman konsep dalam memahami pengaplikasian pembelajaran secara menyeluruh untuk semakin memahami setiap kebenaran-Nya. Pemahaman konsep yang tepat dibutuhkan untuk memahami setiap konsep dalam ilmu kimia. Berdasarkan data penilain sumatif salah satu sekolah Kristen di Jakarta ditemukan bahwa masih kurangnya pemahaman konsep siswa kelas XII MIPA. Tujuan penulisan ini adalah untuk mendiskripsikan tahapan metode pembelajaran jigsaw dalam mengupayakan pemahaman konsep siswa pada topik sel volta kelas XII. Penulisan ini menggunakan metode kualitatif deskriptif. Guru menyusun pembelajaran sesuai dengan langkah penerapan metode jigsaw yang mengarahkan siswa untuk bertanggung jawab dalam pembelajaran secara individu maupun kelompok. Hasil penelitian menunjukkan bahwa penerapan metode pembelajaran jigsaw mampu mengupayakan pemahaman konsep siswa pada materi sel volta. Hal ini didukung dari rata-rata ketercapaian setiap indikator pemahaman konsep dengan menggunakan instrumen pre-test dan post-test. Dalam mengukur pemahaman konsep siswa menggunakan tiga indikator yaitu indikator memahami konsep, menentukan konsep, dan mengaplikasikan konsep. Penulis menyarankan agar penerapan metode pembelajaran jigsaw dalam mengupayakan pemahaman konsep kimia dilakukan dengan memfasilitasi, memperhatikan keterbatasan waktu, dan mengembangkan keseluruhan indikator pemahaman konsep siswa dengan menggunakan metode yang digunakan penulis maupun metode lain.Kata Kunci : metode jigsaw; pemahaman konsep; sel voltaAbstract People is given by God reason so as to gain an understanding of the concept in understanding the application of learning thoroughly to better understand each of His truths. A proper understanding of concepts is needed to understand every concept in chemistry. Based on research data summative assessment from one Christian school in Jakarta, it was found that there is still a lack of understanding of the concept of grade XII MIPA students. The purpose of this writing is to describe the stages of the jigsaw learning method in seeking students' understanding of concepts on the topic of class XII voltaic cells. This writing uses descriptive qualitative methods with portfolio data. The teacher arranges learning according to the steps of applying the jigsaw method which directs students to responsibility in learning individually and in groups. The results showed that the application of the jigsaw learning method was able to improve students' understanding of concepts on voltaic cell material. This is supported by the average achievement of each indicator of concept understanding by using pre-test and post-test instruments. The measuring of the understanding of concepts, students' use there indicators, namely indicators of understanding concepts, determining concepts, and applying concepts. The author suggests that the application of the jigsaw learning method in improving chemistry understanding is done by facilitating, paying attention to time constraints, and developing overall indicators of students' concept understanding using the methods used by the author and other methods.Keywords : concept understanding; jigsaw; voltaic cell

No full textDesign of a Smart Farming Monitoring System Leveraging Internet of Things Technology: Application of the NPKTHCPH -S Sensor
No full textShallot plants are currently widely cultivated, but cultivation is still done manually to control soil conditions. For this reason, with a monitoring system using the NPKTHCPH-S sensor, which can show seven parameters of soil conditions using only one sensor, it is hoped that it will make it easier to see the appropriate soil content and required shallot plants according to the criteria for good shallot plant growth, so that plant growth shallots become more optimal and avoid crop failure. The smart farming monitoring system prototype uses the NPKTHCPH-S sensor, which was developed using the Blynk application by implementing several components such as the NPKTHCPH-S sensor, ESP32, Relay 3.3, RS485-TTL Converter. The NPKTHCPH-S sensor is a reader of soil water content, electrical conductivity, temperature, nitrogen, phosphorus, potassium, and pH in shallot soil. The results obtained from the NPKTHCPH-S sensor test were the most significant seen at 2 pm found a temperature value of 35.6oC with a humidity of 50.7%. And at 11 pm it was found that the temperature was 28.4oC with a humidity of 58.6%. The values for N, P, K, and Conductivity were constant for 9 hours of testing, namely for N was 170mg/kg, for P was 439mg/k, for K was 434mg/k, and conductivity was 1000uS/cm
Bioactivity of Ginger (Zingiber officinale Rosc), Citronella (Cymbopogonnardus (L.) and Cinnamon (Cinnamomum burmannii B) Against Decreased Blood Sugar Levels of Alloxan-induced (Rattus Novergicus)
No full textPurpose: To see the potency of mixed extracts of Ginger (Zingiber officinal Rosc.), Citronella (Cymbopogon nardus (L.) Randle, Cinnamon (Cinnamomum burmanii B.) Against blood sugar levels in alloxan-induced Novergicus Rattus male rats.
Theoretical reference: Insulin resistance is necessary to maintain dysglycemia, where insulin levels are higher than usual. Insulin resistance often occurs in people who are overweight, commonly known as obesity. 2. Pancreatic B Cell Dysfunction, decreased pancreatic beta cell function, and continued increase in insulin resistance, causing chronic hyperglycemia and stage liver disease. 3. Environmental factors are individuals who consume excessive carbohydrates and sugars.
Method: Using Complete Randomized Design (RAL) consisting of 7 groups with 4 repetitions, namely K0 (Normal group), K- (Negative group), K+ (Positive group given meformin), K1, K2, K3 and K4 (mixed extracts of ginger, lemongrass, cinnamon 100, 200, 300 and 400mg/kg bw), The data obtained were analyzed using ANOVA with a sig < 0.05.
Results and conclusion: It showed that the administration of mixed extracts of Ginger (Zingiber officinal Rosc.), Citronella (Cymbopogon nardus (L.) Randle, Cinnamon (Cinnamomum burmanii B.) affected reducing blood glucose levels and improving pancreatic histology. A mixed extract dose of Ginger (Zingiber officinal Rosc.), Citronella (Cymbopogon nardus (L.) Randle, Cinnamon (Cinnamomum burmanii B.) 400 mg/kg bw was most effective in lowering blood glucose levels and improving alloxan-induced pancreatic histology.
Implications of the research: When you want to control blood sugar, you can use a mixture of Ginger (Zingiber officinale Rosc), Citronella (Cymbopogonnardus (L.), and Cinnamon (Cinnamomum burmannii B) extracts in balanced portions).
Originality/Value: Ginger (Zingiber officinale Rosc), Citronella (Cymbopogon Nardus (L.), and Cinnamon (Cinnamomum burmannii B) have potential as herbal medicine ingredients

Hypertension usually starts as a mild disease and then slowly progresses to a severe or dangerous condition. (Mulyadi, 2015). Deep breathing exercises are a form of non-pharmacological therapy, in which the nurse teaches the client how to do deep breaths, slow breaths (maximum inspiration) and how to exhale slowly. Besides being able to reduce pain intensity, deep breathing relaxation techniques can also increase lung ventilation and increase oxygenation in the blood. The general purpose of the application of deep breathing relaxation is to reduce headache in hypertensive patients. With data collection techniques through interviews, observation, and literature study. The results of the application of deep breathing relaxation techniques to reduce headache in hypertensive patients with an initial pain scale before giving the application of deep breathing relaxation 4 (1-10) and after being given deep breath relaxation the pain scale is 0 The author concludes that there is an effect of the application of deep breathing relaxation techniques on Mrs. Y with headaches in hypertensive patients in the working area of the Karang Tengah Public Health Center
