Biofertilizer with Arbuscular Mycorrhizal Fungi (AMF) as the inoculants is needed in organic cocoa cultivation on smallholder plantations in Indonesia. AMF biofertilizer requires a sufficient number of spore inoculants, so it is necessary to multiply isolated spores. Research objective was determining the effect of water stress and mixed types of AMF genus from cocoa roots on spore propagation and root colonization used corn as the host plant. The study used a 2-factors randomized block design and 3 replications. The first factor was water stress consisting of 3 levels (without water stress as a control, soil moisture content 100% of field capacity; light water stress, soil moisture content 70% of field capacity; and heavy water stress, soil moisture content 40% of field capacity), while the second factor was mixed types of AMF genus also consisting of 3 levels (inoculant of genus Glomus only, mixed inoculants of the genus Glomus + Acaulospora, and mixed inoculants of the genus Glomus + Scutelospora. Result of research showed, the interaction of water stress and mixed types of the AMF genus had no significantly affect on the number of spores reproduced, root colonization and host plant growth. The best way of propagation of AMF spores was by heavy water stress treatment with a soil moisture content of 40% of field capacity producing 6,713.40 spores or an increase of 13,326.82%. Mixed inoculants of the genus Glomus + Scutelospora gave the highest number of spores after propagation (6,263.40 pieces) or an increase of 12,427.77%.

The research aims as well as the health conditions of banks that affect profitability. The population and sample in this study are the Core Capital Bank Group 4 Green Banking Pioneers. This study used a sample consisting of 10 Core Capital Bank Group 4 category banks listed on the Indonesia Stock Exchange, namely: CIMB Niaga, Danamon, Panin, Permata, OCBC NISP, BTPN, Maybank Indonesia, BTN, Mega, and BSI. This study uses secondary data obtained through annual bank financial reports for green banking indicators and sustainability reports for CSR during the Covid-19 pandemic from early 2020 to the end of 2021. The analytical method in this study uses multiple linear regression and simple linear regression. The results showed that the Capital Adequacy Ratio had a positive effect on profitability, BOPO had a negative effect on profitability and Non-Performing Loans had a negative effect on profitability.
