Abstrak Penelitian ini bertujuan untuk mengetahui bagaimana cara dan proses pembuatan biogas untuk mendapatkan hasil yaitu gas metana (CH4) secara maksimal dengan menggunakan bahan dari sampah organik makanan rumah tangga dan sampah organik pasar. Jenis penelitian ini adalah eksperimen, dimana penulis melakukan perencanaan, perancangan, pembuatan, dan pengujian secara langsung dilapangan untuk mengetahui hasil dari percobaan tersebut. Proses dalam penelitian menggunakan bahan baku sampah pasar dan sampah organik rumah tangga yang kemudian masing–masing difermentasi selama 12 hari, setelah  dilakukan pengambilan sampel untuk uji nyala dan uji kandungan gas metana yang dihasilkan. Hasil penelitian menunjukan bahwa sampah organik pasar lebih baik digunakan sebagai bahan untuk pembuatan biogas dibandingkan dengan sampah makanan rumah tangga dikarenakan sampah organik pasar tidak memerlukan waktu yang lama untuk terbakar, pada proses pengujian kandungan gas metana sampah organik pasar memiliki kandungan gas metana yang lebih tinggi yaitu 52,8 % dibandingkan dengan sampah organik rumah tangga yang hanya 0,29 %.Kata kunci:  Biogas, Gas metana (CH4), Sampah organik pasar, Sampah organik rumah tangga, fermentasiAbstract This study aims to find out how the way and process of biogas production to obtain the results of methane (CH4) to the maximum by using materials from organic household food waste and organic waste market. This type of research is experimental, where the authors do the planning, design, manufacture, and testing directly in the field to find out the results of the experiment. The process in this study includes the selection of materials divided into 2, namely market waste and household organic waste which then each fermented for 12 days, after sampling for the test flame and test the methane gas content produced. The results showed that the market organic waste is better used as a material for the manufacture of biogas compared with household food waste because the market organic waste does not require a long time to burn, in the process of testing the methane gas content of organic waste market has a higher methane gas content 52.8% compared with household organic waste which is only 0.29%.Keywords: Biogas, Methane (CH4), Organic waste market, Household organic waste, fermentation

Reading comprehension part is being the most difficult part in TOEFL based on the researcher's observations. Although they were given some strategies on reading comprehension, but there were still many students who found difficulty when solved the problems. One of the external factors cause the lower reading comprehension skills of students that is influenced by teaching method in the classroom and students' learning motivation as internal factors.The method which was applied in this research was experimental study in order to know the difference and effect between Direct Instruction teaching method and Roundtable Cooperative teaching method for teaching reading comprehension on TOEFL. The data were analyzed by using multifactor analysis of ANOVA 2x2 and tukey test. Based on the results of the analysis, it can be concluded that Roundtable Cooperative teaching method is significantly different from Direct Instruction teaching method to teach reading comprehension on TOEFL. The reading comprehension of the students who have high motivation is significantly different from that of those who have low motivation. Roundtable Cooperative teaching method is more effective than Direct Instruction teaching method to teach reading comprehension on TOEFL for the students who have high motivation; however for the students who have low motivation, Direct Instruction teaching method is more effective than Roundtable Cooperative teaching method to teach reading comprehension on TOEFL. Thus, there is an interaction between teaching methods and students' learning motivation for teaching reading comprehension on TOEFL. The effectiveness of the teaching method depends on the degree of the students' motivation.

Youtube beyond the formal classroom. Methods: A qualitative inquiry approach was employed in this study.
