Abstract

The anaerobic decomposition process of organic matter in EFB from straw mushroom media waste with the addition of substrates from manur, sludge, EM4 and POME is an alternative treatment of organic material by producing compost and biogas. This study aims to determine the effect of the use of substrate in the composting process of EFB from the waste media of straw mushrooms and the content of chemical nutrients in compost EFB with anaerobic fermentation. The composting process is carried out by inserting EFB in anaerobic bioreactors and adding substrates containing the starter. During the decomposition process observations were carried out every week and every two weeks. The parameters analyzed are temperature, pH, C/N, available P, K-dd and biogas volume. The results showed that the anaerobic organic matter decomposition process carried out for 8 weeks contained the highest biogas production when treated using a substrate from EM4 with a biogas volume of 10L / day with temperatures reaching 30oC having a pH characteristic of 8.79; Nitrogen 1.04 - 1.68%, C-organic 15.30%, C / N 11.71, P-available 0.69 and K-dd 1.13%.

Abstract

Mesofauna tanah merupakan fauna tanah yang berperan dalam proses dekomposisi material organik di dalam tanah dan dapat menjadi bioindikator kesuburan tanah. Peningkatan bahan organik seperti biochar pada tanah dapat meningkatkan populasi dan aktivitas mesofauna tanah. Penelitian bertujuan untuk mendapatkan keanekaragaman mesofauna tanah dan aktivitas mikroorganisme tanah terbaik pada berbagai dosis biochar, dosis pupuk majemuk NPK, dan interaksi antara biochar dan pupuk majemuk NPK. Penelitian dilaksanakan di lahan perkebunan Politeknik Negeri Lampung dan Laboratorium Analisis Politeknik Negeri Lampung, pada Juli 2021 hingga Januari 2022. Penelitian dirancang menggunakan Rancangan Acak Kelompok (RAK) disusun secara split-plot yang terdiri atas dua faktor perlakuan berupa dosis biochar (B0 = tanpa biochar, B1 = 10 ton/ha, dan B2 = 20 ton/ha) dan dosis pupuk majemuk NPK (P0 = tanpa pupuk, P1 = 350 kg/ha, dan P2 = 750 kg/ha), diulang 4 kali. Variabel pengamatan adalah populasi mesofauna tanah, indeks keanekaragaman mesofauna tanah, indeks dominasi mesofauna tanah, dan aktivitas mikroorganisme tanah. Hasil penelitian menunjukkan bahwa perlakuan dosis biochar 20 ton/ha merupakan perlakuan terbaik terhadap populasi mesofauna tanah, indeks keanekaragaman mesofauna tanah, indeks dominasi mesofauna tanah, dan aktivitas mikroorganisme tanah. Perlakuan dosis pupuk majemuk NPK 700 kg/ha merupakan perlakuan terbaik terhadap populasi mesofauna tanah, indeks keanekaragaman mesofauna tanah, dan indeks dominasi mesofauna tanah, sedangakan pada aktivitas mikroorganisme tanah perlakuan tanpa pupuk majemuk NPK merupakan yang terbaik. Interaksi terbaik kombinasi perlakuan berbagai dosis biochar dan dosis pupuk majemuk NPK tarbaik yaitu pada perlakuan dosis biochar 20 ton/ha dengan dosis pupuk majemuk NPK 700 kg/ha.

Abstract

Empty fruit bunches (tankos) are a by-product, which is equal to the amount of CPO, which is 23%. Several attempts have been made to utilize tankos as a growing medium for mushroom, but these efforts have not been optimal. This is because they only take the edible mushroom product once, even though the waste still has the potential as a growing medium for the next mushroom, as well as the potential for compost. The purpose of the study was to determine the effect of new EFB, EFB that have been used once, and twice (used EFB I and used EFB II) on the pattern and daily production of straw mushrooms on the pilot plant scale.Pilot plant scale research has been carried out at CV Lintang Agro Farm Raman Adji East Lampung with three treatments, namely new EFB, used EFB I, and second-hand boarding houses. The study was repeated two times. The raw materials used are EFB, lime, katul, mushroom seeds, second-hand tankos I and second-hand EFB. The stages of the research process began with the preparation of EFB, the process of making edible mushrooms and observing the results of the research. The results showed that (1) EFB could be used as a planting medium for straw mushrooms 3 times, (2) the most productive production of straw mushrooms with EFB media was carried out until day 20 of the inoculation process, and (3) planting straw mushrooms on EFB media was able to reduce cellulose, hemicellulose, and lignin content significantly.
