Tropical peat is an important natural ecosystem, and its natural state plays an important role in climate regulation. These peatlands globally provide vital environmental benefits, especially in case of their enormous carbon storage potential. Peat land also functions as a source of livelihood for the community, especially for agricultural activities, and this will lead to the potential loss of carbon stock in peatlands. This study examines plants' potential to create Carbon to offset carbon dioxide emissions and different land use types. The study focused on Central and West Kalimantan, Indonesia. Peat soil samples were collected from various types of land from 0-15, 15-45, and 45-100 cm depth and analyzed for physical and chemical parameters. The cylinder chamber method with infrared gas analysis model EGM-4 was used to measure CO2 emissions. Plant carbon sequestration was measured in a 6.25 m2 plot in the study sites of Central Kalimantan. The study showed that type of commodity and period of management affect the carbon content in peat with different land uses, and it is affected by soil bulk density, organic matter content, and CO2 emission. In the case of study crops, oil palm, rubber, corn, and mustard emit the highest CO2. Further, corn crop has the highest potential to fix carbon dioxide and produces more Carbon per hectare than the Carbon emitted from corn-planted under peatland conditions. The study indicated that the type of commodity and the time of its management affected the carbon content in peat with different land uses, and carbon content got the change with soil bulk density and soil organic matter content.
Selain kesehatan masyarakat, ketahanan pangan adalah isu utama saat Pandemi Covid 19 dan menjelang memasuki masa endemi Covid 19. Sebagai negara dengan jumlah penduduk mencapai 269,6 juta jiwa lebih, Indonesia memerlukan kemantapan ketersediaan pangan. Intensifikasi dan ekstensifikasi pertanian sudah selayaknya dilakukan. Namun demikian, diversifikasi pangan menjadi hal lain yang perlu diperhatikan. Beras sebagai sumber karbohidrat dan sebagai bahan pokok pangan utama, selama ini sudah mendominasi kebutuhan kecukupan pangan. Lebih lanjut, perlu dilakukan diversifikasi sumber karbohidrat lain yang bisa dijadikan sumber pangan. Ubikayu adalah salah satu tanaman yang memungkinkan sebagai alternatif, selain beras. Total produksi ubikayu yang mencapai 16,67 juta ton tahun-1 pada tahun 2020-2021, menjadi gambaran potensi tanaman ini sebagai sumber pangan. Disisi lain, mengingat potensi terjadinya degradasi kesuburan tanah pada lahan yang dipakai untuk budidaya tanaman ubikayu monokultur, maka perlu dilakukan upaya pengelolaan tanah dan tanaman untuk usahatani ini. Dilaporkan dari beberapa hasil penelitian, bahwa pola tanam tumpangsari, termasuk agroforestri, direkomendasikan untuk dipakai dalam budidaya tanaman ubikayu. Penurunan hasil yang didapatkan dari tanaman ubikayu pada pola tanam tumpangsari atau agroforestri dibandingkan monokultur, masih bisa ditoleransi mengingat nilai kesetaraan lahan pada polatanam ini dan manfaat ekologi dari pohon bisa didapatkan pada sistem agroforestri.
The purpose of this training is to increase the understanding of journal managers regarding journal management, especially with regard to national and international indexing, and improve journal management competence (skills) related to how to manage journals, especially related to national and international indexing. Based on the results of the analysis of the responses of the training participants, it can be concluded that: The scientific journal management training that was carried out was very useful in improving the quality of scientific journal management in the IAIN Palangka Raya area in particular and in the city of Palangka Raya in general. of course Have a direct positive impact on increasing the acceptance of scientific journals. In addition, from the participants' responses during the training and mentoring it was concluded that: Improving the quality of management of scientific journals is a very basic component affecting the quality of published journals
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
