Abstract

Proses gasifikasi terjadi di reaktor gasifikasi yang disebut gasifier. Di antara jenis proses gasifikasi, yang paling sederhana dan mampu menghasilkan gas dengan kualitas yang cukup baik adalah jenis gasifikasi downdraft. Dalam penelitian ini akan digunakan gasifier downdraft di mana udara pembakaran akan masuk dari bagian atas atau samping di zona pembakaran dan syngas akan keluar dari bagian bawah reaktor. Pada penelitian ini, gasifikasi biomassa berbahan baku kayu karet dengan tujuan untuk mengetahui pengaruh AFR dan suhu terhadap nilai kalor dan komposisi syngas dengan menggunakan downdraft gasifier dan batubara sebagai stabilisator. Hasil dari penelitian ini terdapat persentase penurunan CO, H2, dan CH4 karena AFR meningkat, pada 0,64 AFR kadar CO2 menurun secara signifikan pada suhu 700ºC - 800ºC yaitu sebesar 6,01% tanpa batubara. Kondisi optimum terbaik terdapat pada suhu 0,64 AFR dan suhu 800ºC, pada kondisi tersebut didapatkan kadar CO2 sebesar 18,77%. Kondisi operasi terbaik pada penelitian terjadi pada air fuel ratio (AFR) 0,64, temperatur 800ºC dengan batubara sebesar 33,95% dan tanpa batubara sebesar 31,54%.

Abstract

Garbage that is not managed properly will cause pollution to water, soil and air pollution. Garbage is often a worthless item, causing no awareness of the existence of this waste. Pondok Pesantren Nidhomuddin, Negara Ratu Natar Village, South Lampung fosters approximately 140 students consisting of 60 male students and 80 female students. Pondok Pesantren Nidhomuddin have facilities such as 1 mosque, 7 classes each for male and female students, 10 bathrooms for male students and 18 bathrooms for female students. Based on the problems above, this activity was carried out to provide solutions to the problems faced by students in Pondok Pesantren Nidhomuddin. This service activity was carried out at Pondok Pesantren Nidhomuddin,Negara Ratu Natar Village, South Lampung. the steps of the community service activities carried out are preliminary studies and location surveys, mapping problems related to organic and organic waste processing, socialization activities and assistance related to organic waste management using the composting method and the ecobrick method for inorganic waste. The material presented in the socialization activity is related to what is organic and inorganic waste, waste processing procedures, organic and inorganic waste processing, environmental sanitation, and finally giving questionnaires at the beginning and end of the workshop activity to evaluate community service activities. Based on the results of the questionnaire given to the socialization participants, there was an increase in the knowledge of the students regarding waste management and environmental sanitation. It is hoped that the students can implement good and correct waste processing in Pondok Pesantren Nidhomuddin.

Abstract

The decomposition process of organic waste, including banana peels, can produce greenhouse gases such as methane. These gases contribute to climate change and global warming if not managed properly. One way to utilize banana peel waste is by converting it into liquid organic fertilizer, which can help farmers produce high-quality liquid organic fertilizer at an affordable price. The impact of using chemical fertilizers and pesticides includes the disruption of soil nutrient balance and pesticide residue content in food products. Based on this, research has been conducted by combining organic fertilizer material from banana peel waste with organic pesticide material from yam bean and galangal waste, thus providing a dual function as an organic fertilizer and a biopesticide in one package. This serves as an effective solution for addressing the scarcity of organic fertilizers and pesticides.

Abstract

Pengembangan membran keramik berpori dengan memanfaatkan material alam sebagai bahan baku keramik berpeluang menjadi kajian yang relatif dan inovatif. Penelitian ini bertujuan membuat sampel produk membran keramik berpori berbahan baku bentonit, zeolit dan bahan aditif serbuk kayu menggunakan proses ekstrusi dengan variasi komposisi bahan bakunya. Pada penelitian ini dilakukan pengujian sifat fisik sampel produk yaitu susut volum, susut massa, densitas, porositas, dan serapan air.. Dari data hasil penelitian diperoleh kondisi optimum terjadi pada jenis sampel membran keramik CF1 dengan nilai susut volume 6 %, susut massa 4 %, uji densitas 1,347 gr/cm3, serta porositas dan serapan air masing- masing sebesar 22,64% dan 16,02%.  Penambahan serbuk kayu sebagai aditif menurunkan densitas, menaikan porositas dan daya serap air dari sampel. Sampel membran keramik berpori yang dihasilkan memiliki ukuran pori yang relatif seragam dengan rentang diameter sekitar 10 – 20 μm, sehingga dapat digunakan sebagai material filter.
