Coffee is very important agro industry in Bali Province. The coffee center in Bali which is already famous for its geographic indication protection status is Kintamani District, which is the largest producer of Arabica coffee and an icon of Arabica coffee in Bali. Therefore, efforts are needed to maintain coffee production through the selection of fertilizers that do not harm the environment, for example biological fertilizers derived from arbuscular mycorrhizal fungi (AMF). This study aimed to find the best growing media composition and optimal soil water content and the interaction between the two treatments for endomycorrhizal spore propagation. This research was arranged in a completely randomized design (CRD) with 2 factors and 4 replications. The first factor was composition of growing media which consisted of four levels, i.e. Mt (soil only), Mp (soil and volcanic sand with ratio of 1:1/v:v), Mk (soil and compost with ratio of 1:1/v:v), and Mc (soil, volcanic sand, and compost with ratio of 1:1:1/v:v:v). The second factor was water stress which consisted of three levels, i.e. A0 (100% field capacity), A1 (70% field capacity), and A2 (40% field capacity). The highest spore multiplication results were obtained in the combination treatment of MpA0 as much as 55,00 spores with an increase of 120%. Meanwhile the combination treatment of MkA2 produced the lowest spores as much as 34.25 spores with an increase of 37%.

Pulukan Village, located in the Jembrana Regency of Bali, is one of the primary communities that produce organic cocoa. The huge demand for organic cocoa beans has not been satisfied due to the poor production per hectare. One of the causes is that cocoa farmers in the village have trouble obtaining the recommended volumes of organic fertilizers and biopesticides. To raise the yield of organic cocoa, this service is provided to farmers to enhance their knowledge and ability to create organic fertilizers and biopesticides from local components. The activities are implemented through counselling and training on producing organic fertilizers and biopesticides, followed by support in applying organic fertilizers and biopesticides. Participants in training and mentoring are encouraged to work together and learn concurrently. The implementation of the counselling on the production of organic fertilizers and biopesticides was excellent, as indicated by the fact that 93.33 per cent of participants said they comprehended the material presented very well, and 100 percent said it was fascinating and very beneficial. Participants could produce excellent organic fertilizers and biopesticides due to training activities involving direct practice. As a result of training in plots, organic fertilizers, and biopesticides can improve farmers' ability to directly implement fertilizing methods and disease pest management in organic cocoa farming. Applying organic fertilizers and biopesticides in the plot revealed that cocoa trees treated with organic fertilizers and biopesticides had greater growth and fewer disease-causing insect infestations than control trees.This motivated the service volunteers to implement the plot's best practices on their organic cocoa crops.

The Application of Plant Growth Promoting Rhizobacteria (PGPR) and the Waste of Catfish Tank Water with Drip Irrigation System towards the Growth and the Yield of Pakcoy (Brassica rapa L.). Pakcoy (Brassica rapa L.) is a leaf vegetable commodity belonging to the Brassicaceae family. The productivity of the mustard plant has fluctuated in recent years. To handle that, it is necessary to innovate the treatment techniques in the cultivation of pakcoy. The application of PGPR and waste of catfish tank water using a drip irrigation system is one solution to improve the quality and production of pakcoy. This research aims to find the best dose of PGPR when combined with the waste of catfish tank water. This research used a split-plot randomized block design with 2 factors. The first factor was a resource of irrigation water which consists of 2 treatments level, namely the irrigation without the waste of catfish tank water and irrigation with the waste of catfish tank water. Meanwhile, the second factor was the dose of PGPR which consists of 5 treatments level, i.e. PGPR dose of 0, 100, 200, 300, and 400 ml/plant. The results showed that the application of PGPR at a dose of 200 ml/plant was able to provide better growth and yield of pakcoy than the other PGPR doses. This can be seen from the fresh weight of the pakcoy crown, which is 42.64 g. Furthermore, the factor of irrigation water sources with the waste of catfish tank water provided the highest yield of pakcoy for all observation variables. The interaction of PGPR dose of 200 ml/plant and waste of catfish tank water gave the highest crown fresh weight of 23.45 g.
