Saat sekarang ini sampah sudah mulai dipandang sebagai sumber daya yang memiliki nilai ekonomi. Pengolahan sampah menjadi produk yang lebih berguna mulai aktif dilakukan seperti menjadikan sampah untuk energi, kompos, pupuk atau sebagai bahan baku dalam industri. Sampah organik dapat diolah menjadi Eco enzyme yang memiliki manfaat ganda. Cairan Eco enzyme ini multifungsi dan aplikasinya dapat meliputi rumah tangga, pertanian dan juga peternakan. Program ini bertujuan menjadi solusi untuk menciptakan lingkungan yang bersih (Zero Waste) sekaligus untuk meningkatkan ekonomi masyarakat sekitar. Kegiatan ini mengenalkan inovasi alat fermentor eco enzyme yang dapat digunakan lebih efektif. Metode pelaksanaan kegiatan adalah dengan pelatihan yang dilakukan secara langsung  dan dilanjutkan dengan pendampingan pembuatan eco enzyme dengan menggunakan eco fermentor dan pembuatan handsanitizer. Kegiatan ini menghasilkan peningkatan pemahaman mitra dalam produksi handsanitizer. Handsanitizer yang dihasilkan selanjutnya  diuji efektivitasnya dalam membunuh bakteri. Kegiatan ini diharapkan dapat dilanjutkan oleh mitra Bank sampah dalam memproduksi handsanitizer sehingga dapat meningkatkan ekonomi. Workshop on the production of Eco enzyme as a Hand Sanitizer in Improving the Economy of the Village Community of Lembah Damai  Abstract Nowadays, waste has begun to be seen as a resource that has economic value. Processing waste into more valuable products has started to be actively carried out, such as making waste for energy, compost, fertilizer, or as raw material in the industry. Organic waste can be processed into Eco enzyme, which has multiple benefits. This Eco enzyme liquid is multifunctional, and its applications can include households, agriculture, and livestock. This program aims to be a solution to create a clean environment (Zero Waste) as well as to improve the economy of the surrounding community. This activity introduces an innovative eco-enzyme fermenter that can be used more effectively. The method of implementing the action is through training which is carried out directly and followed by assistance in making eco enzymes using an eco fermenter and hand sanitizer. This activity resulted in an increased understanding of partners in the production of hand sanitizer. The hand sanitizer produced is then tested for its effectiveness in killing bacteria. This activity is expected to be continued by Waste Bank partners in creating hand sanitizer to improve the economy

The aim of this study was to test several endophytic fungi isolates with high antagonistic power against seed borne fungi in vitro and their effect on the growth of chili (Capsicum annuum L.) seedlings in vivo. This research was conducted at the Plant Disease Laboratory and Greenhouse Faculty of Agriculture, Riau University from October 2018 to February 2019. This research was conducted experimentally using a completely randomized design (CRD) consisting of 5 treatments and 4 replications. The treatment of endophytic fungi was applied using the seed immersion method. The results showed that giving the endophytic fungi Rhizictonia sp., Cephaloporium sp., T. virens from oil palm roots and T. virens from oil palm stems were able to suppress the incidence of seed-borne pathogenic fungi Fusarium sp., Colletotrichum sp. and Aspergillus sp.. Provision of endophytic fungus T. virens from oil palm roots can increase seed germination capacity by 14%, number of live seeds by 17% and increase seedling height and leaf number.
