This study aims to determine the differences in student achievement who are taught using interactive multimedia drills model with students who are taught using science comic media. This type of research is experimental research. The population in this study is all students of class VII MTs. The State of Selong Model and the sampling was determined by using cluster random sampling technique to select the class and simple random sampling to select the students in that class. The second sampling technique is random sampling by drawing lots, cluster random sampling, namely the class is divided into experimental class I, namely the class that is taught using interactive multimedia drills model (class VII-E) and the experimental class II, namely the class that is taught using comic media. science (class VII-F), each of which consists of 36 students. And simple random sampling, where students are drawn after data collection to reduce the sample to 30 students to facilitate hypothesis testing. The data collection technique used post-test while the data analysis technique to test the hypothesis was the t-test. The results of data analysis using t-test showed that there were differences in student achievement who were taught using interactive multimedia drills model with students who were taught using science comic media. This can be seen in the post-test results where t-count > t-table is 2.206 > 2.002. Thus H0 is rejected and Ha is accepted. This means that there are differences in student achievement who are taught using interactive multimedia drills model with students who are taught using science comics

Abstract: Physical activities include all body movements ranging from a small movement to a movement that involves several large muscles such as lifting the arms and legs. During a physical activity, the body temperature will increase, and as a compensatory mechanism, the body will sweat and release several kinds of electrolyte such as magnesium, sodium, and potassium. Potassium is a macronutrient that is widely available in the intracellular fluid (ICF). The normal value of serum potassium is 3.5-5.0 mmol/L. This study aimed to obtain the comparison of blood potassium levels of fourth year students of the Faculty of Medicine, University of Sam Ratulangi Manado, before and after vigorous physical activities. This was an experimental study with a one group pretest-posttest design. There were 21 male students as respondents obtained by using the simple random sampling method. Data were analyzed by using the paired t-test. The physical activity conducted was playing futsal for 2x20 minutes with a break of 10 minutes in between. The results showed that the average of serum potassium level before doing the physical activity was 3.7 mmol/L, and the average of the serum potassium level after doing physical activity was 3.8 mmol/L. The paired t-test showed a p value of 0.061 (p>0.05). Conclusion: There was no significant difference between serum potassium levels before and after vigorous physical activity, Keywords: potassium, physical activity, vigorous intensity Abstrak: Aktivitas fisik meliputi semua gerakan tubuh mulai dari gerakan kecil sampai gerakan yang melibatkan pergerakan beberapa otot besar seperti saat mengangkat lengan atau tungkai. Ketika melakukan aktivitas fisik, terjadi peningkatan suhu tubuh dan sebagai mekanisme kompensasinya tubuh akan mengeluarkan keringat dan beberapa jenis elektrolit misalnya magnesium, natrium dan kalium. Kalium merupakan salah satu makronutrien yang banyak terdapat dalam cairan intrasel (CIS). Nilai normal kalium serum yaitu 3,5-5,0 mmol/L. Penelitian ini bertujuan untuk mengetahui perbandingan kadar kalium darah sebelum dan sesudah aktivitas fisik intensitas berat pada mahasiswa Fakultas Kedokteran Universitas Sam Ratulangi Manado angkatan tahun 2011. Jenis penelitian ini eksperimental dengan rancangan one group pretest-posttest design. Responden diperoleh menggunakan metode simple random sampling. Hasil pengukuran kadar kalium serum sebelum dan sesudah aktivitas fisik intensitas berat dianalisis menggunakan uji paired t-test. Aktivitas fisik yang dilakukan yaitu bermain futsal selama 2x20 menit dengan diselingi istirahat selama 10 menit. Hasil penelitian memperlihatkan dari 21 responden (laki-laki) rerata kadar kalium serum sebelum melakukan latihan fisik 3,7 mmol/L, dan rerata kadar kalium serum sesudah melakukan latihan fisik 3,8 mmol/L. Uji paired t test menunjukkan nilai p=0,061 (p>0,05). Simpulan: Tidak terdapat perbedaan bermakna antara kadar kalium serum sebelum dan sesudah latihan fisik intensitas berat.Kata kunci: kalium, aktivitas fisik, intensitas berat

This research was Statistic Group Comparison that used Simple Random Sampling. There were two groups that were given different treatment. The first group was the experimental class 1 as VIII C that was taught by using Scaffolding Technique, and the second group was the experimental class 2 as VIII B that was taught by using Write Pair Square (WPS) Technique. The result of data analysis showed that the result of T-test is 3.628 and the result of T-critical is 2.056, because the T-observed > T-critical. It means that there was a significant different achievement between the students those which one was better after teaching by using WPS and those which one was better after teaching by using Scaffolding toward students’ descriptive text writing ability

<span class="fontstyle0">This study aims to analyze the income of paddy farming in members and non-members of the community granary group, and to know the impact of the membership of the granary group on the income of paddy farming. This research was conducted in Bontoloe Village, Galesong Sub District, Takalar District, South Sulawesi Province. Sampling was done by two methods, first for sample of granary member using purposive sampling method, second fornon-member of granary using simple random sampling method. So the total sample in this study were 34 farmers. Data analysis used is the analysis of different test (t test) and multiple linear regression. The results showed that the income earned by farmer members of the granary group amounted to Rp 9,386,227.00, while the income earned by non-member farmers in the granary group was Rp 9,175,144.00. Differences in paddy production, revenue, and income levels between member farmers and non-members of the granary group based on t test proved not significantly different. Factors that significantly affect the income level of paddy farming are land area, paddy seed price, pesticide price, and labor wage. While the impact of membership of community granary group was not significant to the income of paddy farming. But simultaneously (land area, price of paddy seed, price of urea fertilizer, phonska fertilizer price, pesticide price, labor wage, dummy member) can affect paddy farming income of 84.99%.</span>
