Abstract

Plastic and biomass waste disposal will increase if it is not accompanied by appropriate, efficient, and effective waste treatment. Recent research on the yield of charcoal produced by co-pyrolysis has shown that the product of co-pyrolysis of plastic and biomass raw materials is a beneficial additive with a variety of applications, ranging from soil and water improvement, increasing agricultural yields, fuel cells, supercapacitors, as a support/ catalysts, sustainable chemistry, and carbon sequestration. Therefore researchers need to ensure the quality of the results of co-pyrolysis in the form of biochar obtained from any raw material and process to provide maximum benefits, mainly from biomass and plastic raw materials. This study aims to review the formation of biochar from the co-pyrolysis of plastic and biomass raw materials by examining the raw materials, pyrolysis techniques, and the type of reactor used to identify the appropriate parameters. This review discusses biochar production techniques, pyrolysis technology mechanisms, types of pyrolysis, the type of reactor used, the properties of both biomass and plastic raw materials and the properties of biochar produced from various raw materials for comparison. Biochar will be obtained with maximum yield quality from the results of mixing the raw materials for biomass and plastic and optimal operating conditions. It can be an alternative in the bio-oil and syngas energy sector and reduce carbon emissions.

Abstract

Biochar has potential as alternative solution to overcoming the problem of renewable energy needs, improving land structure for agriculture, and supplying industrial needs as absorbent material with high absorption. Biochar has a high carbon content that it obtains from the biomass pyrolysis process. In this experiment, the main material was biomass obtained from the Spirulina platensis residual (SPR). The temperature effect on the yield and characteristic of biochar from SPR were studied. The research was conducted in the fixed-bed reactor with 40 mm of inside diameter, 44 mm of outside diameter, and 600 mm of height. The reactor was supported with an electrical heater from a nickelin coiled along the outside surface of reactor. The experiments were carried out with temperatures ranging from 300 to 700ºC. Biochar analysis was performed by the Brunauer-Emmett-Teller (BET) method. Results indicated that the yield of biochar decreased with increasing temperature. Conversely, the surface area, the total volume of pore, and the radius of pore increase with an increase in temperature. The best temperature conditions to produce the biochar are 600ºC, with the product yield of 27.9 wt.%, surface area of ​​13.5 m2/gr, total pore volume of 0.041 cc/gr, and diameter of 2,688 nm.

Abstract

Fermentasi kakao menjadi salah satu makanan fungsional yang memiliki banyak kandungan gizi yang baik untuk kesehatan. Biji kakao hasil fermentasi memiliki kadar protein yang lebih tinggi daripada biji kakao tanpa fermentasi. Namun, masih banyak masyarakat yang masih belum mengetahui tentang kandungan gizi dari kakao fermentasi salah satunya adalah Kelompok Wanita Tani (KWT) di Dusun Banjardowo, Desa Gedangrejo, Kapanewon Karangmojo Kabupaten Gunungkidul. Tujuan dari pengabdian ini adalah meningkatkan pengetahuan KWT mengenai nilai gizi dan manfaat fermentasi kakao. Pengabdian ini diikuti oleh KWT yang berjumlah 15 orang dengan metode penyuluhan secara tatap muka menggunakan media power point, dan pada awal dan akhir kegiatan diberikan pengukuran pengetahuan menggunakan kuesioner pre dan post test. Hasil dari pengabdian yang dilakukan pada KWT ini adalah terdapat peningkatan pengetahuan secara signifikan sebelum dan sesudah dilakukannya penyuluhan (p<0,05). Selain itu, terjadi perubahan kategori pengetahuan peserta dari mayoritas berada pada kategori kurang (73,33%) menjadi mayoritas berada pada kategori baik (86,67%) setelah dilakukan penyuluhan.
