ABSTRACTA green house experiment were conducted to study the application of âcompost plusâ on the growth of Orthosiphon aristatus. The experiment was designed in Complete Randomized Design with factorial and five replicates. The first factors were fertilizer application (compost plus, compost, and control). The second factors were 3 kinds of soil (i.e. soil from Cibinong, Ciomas, and Sukabumi). The result showed that compost plus application increased 113.90 gram/pot of dry weight of Orthosispon aristatus leaves compared with compost application and control in 3 kinds of soil.Key words : Compost plus (compost + microbes), Orthosispon aristatus

Background: Hypertension or increased blood pressure is often referred as the silent killer because it usually does not show significant signs and symptoms. Thus, almost all patients do not realize if they suffer from hypertension. The Basic Health Research (Riskesdas) 2007 reported that the prevalence of hypertension in the population aged over 18 years old in Indonesia was 31.7%. Because of the increasing prevalence of hypertension in adolescence, it is necessary to take precautions. This study aimed to examine the relationship between demographic factors and body mass index with the prevention of hypertension in adolescentsSubjects and Method: This was a cross sectional study conducted at Muhammadiyah 1 Senior high school, Yogyakarta, from May 2017 to February 2018. A sample of 80 students was selected for this study. The dependent variables were prevention behavior. The independent variables were age, sex, body mass index (BMI), and residence. The data were collected by questionnaire and analyzed by Chi square.Results: 48 (60%) students had good hypertension prevention behavior. Female (OR= 3.00; p= 0.030), urban residence (OR= 2.78; p= 0.040), and normal body weight (OR= 4.30; p= 0.001) increased behavior of hypertension prevention, and they were statistically significant. Older age (OR= 1.59; p= 0.220) increased behavior of hypertension prevention, but it was statistically non-significant.Conclusion: Female, urban residence, normal body weight, and older age increase behavior of hypertension prevention.Keywords: hypertension prevention behavior, demographic factorsCorrespondence: Ratna Indriawati.

Coal and Mineral mining activities have a high risk of ecosystem changesthat affect the environment, let alone the mining is carried out openly. In order torestore the condition of the land in such a way that it can function and to be effectivein line with its allocation, the ex-mining area must be restored. Reclamation andpost-mining activities shall be conducted by every holder of Mining Business Permit(IUP) Exploration and IUP Production. Holders of IUP Exploration must firstlyprepare reclamation and post-mining plans in the permit process. The implementationof reclamation and post-mining activities by holders of IUP Production Operationand Special Mining Business Permit (IUPK) Production Operation must complywith the principles of : (1)protection and management of mining environment; (2)working safety and health; and (3) mineral and coal conservation. To determinethe success of the land that has been reclaimed and the post-mining activities havebeen complied, if an evaluation has been made by the competent officials and it isstated that the reclamation and post-mining activitie shave been performed well inaccordance with prevailing regulations.

Tujuan penelitian ini adalah untuk mengetahui apakah ada perbedaan yang berarti penggunaan model pembelajaran kooperatif tipe two stay two stray (TSTS) dan ekspositori terhadap hasil belajar siswa kelas VIII SMP Negeri 18 Palembang. Penelitian ini merupakan penelitian eksperimen. Populasi dalam penelitian ini adalah seluruh siswa kelas VIII SMP Negeri 18 Palembang tahun ajaran 2015/2016 dengan sampel kelas VIII2 sebagai kelas eksperimen dan kelas VIII6Â sebagai kelas kontrol. Dari perhitungan hasil belajar siswa dengan menggunakan model pembelajaran kooperatif tipe two stay two stray (TSTS) diperoleh nilai rata-rata Â = 68,085 dan hasil belajar siswa dengan menggunakan model pembelajaran ekspositori diperoleh nilai rata-rata Â = 52,30. Setelah datanya dianalisis ada perbedaan kedua rata-rata yang mana rata-rata kelas eksperimen lebih baik dari rata-rata kelas kontrol. Kemudian dari hasil analisis data dengan menggunakan statistik uji-t diperoleh Â = 5,272, untuk Â = 5% dan dk = 69 didapat Â = 2,00. Jadi, â‰¥Â maka H0 ditolak berarti Ha diterima. Sehingga hipotesis yang menyatakan â€œAda perbedaan yang berarti penggunaan model pembelajaran kooperatif tipe two stay two stray (TSTS) dan ekspositori terhadap hasil belajar siswa di kelas VIII SMP Negeri 18 Palembangâ€ dapat diterima kebenarannya

This type of research is experimental research. The population in this study were all seventh grade students of SMP Muhammadiyah 4 Palembang in the academic year 2021/2022 with a sample of class VII U3 as the experimental class and VII U2 as the control class. After learning using the drill method based on the Kahoot application, the average value is and the standard deviation is S1=14,8165. While learning using the drill method without the Kahoot application, the average value is and the standard deviation is . Based on the criteria for testing the hypothesis, the value of and means that is in the rejection area of Ho, which means Ha is accepted. Thus the hypothesis which states "There is a significant effect of the drill method based on the kahoot application on the mathematics learning outcomes of students with integer operations in class VII SMP Muhammadiyah 4 Palembang.", is accepted as true
