A construction method that utilizes local materials and is environmentally friendly. Researchers designed a training model as an introduction to the riverbank protection technology. This study describes the effectiveness of training in increasing community skills in making riverbank protection constructions. Materials and Methods: This research is a quantitative study with a quasi-experimental approach. Participants of 60 farmers were divided into two groups. The 2F group consisted of 30 farmers trained by two facilitators while five facilitators trained the 5F group. The skill test is divided into four aspects, namely Land Preparation, Foundation Work, Reinforced Concrete Beam Work, and Bag Concrete Work The data analysis technique used in this study is an Independent-Sample T-Test on four aspects of skills. This test is used to determine whether or not significant differences exist between the two groups. Results: The descriptive analysis results showed an increase in the participants' skills after the training. The training effectiveness in the 5F group was higher than that of the 2F group. Statistical analysis showed a significant difference in skills improvement between 2F and 5F. Therefore, the number of facilitators at the training gives a significant meaning to the participants' skills achievement. Conclusion:The analysis results outline that RBC training in the community effectively improves the skills of participants.

INTRODUCTION Erosion of riverbank due to flow dynamics triggers environmental degradation. Land use patterns from forests to agricultural land and settlements impact hydrological conditions of watersheds. The erosion and landslides are related toerosion ofriver cliffs 1 . The kinetic energy in the river flow causes the exfoliation of the soil on the river cliffs. Erosion of river cliffs or soil particles' release can lead to the deposition, muddying, and superficiality of rivers and the water body's closing. This condition caused flooding due toa decrease in river capacity 2 . The build-up of sediment on the body of the river can also lead to the cover of springs. The series of physical events have had an impact on the deterioration of river quality. Specifically, river cliff protection efforts are taking sediment control measures on the river. Retaining wall and sheet piles as an alternative if the structural protectionsin the river 3 . Efforts to build the structure should involve the community. This will impact the development of community skills towards protecting river quality, as perpetrators who define their own lives. Researchers are trying to introduce an RBC (Ring Bag Concrete) technology as a simple cliff-climbing construction. This construction is easy to adopt by the community. This construction consists of two parts, namely the upper building and the lower building. The lower building is a foundation using a concrete precast ring (Ring Concrete = RC) diameter 0.8 – 1.0 m with a thickness = 10 cm. This material is a product of the local community industry that uses local natural resources. The bond between RC with a 20/20 cm beam ring that binds with haunted. The upper building is a cliff protector with a sack filled with the concrete mixture by composition 1 PC: 2 sand: 2.5 crush stone. BC is arranged vertically with an angle between 45 o -60 o . 1.5 – 2 m high so that the forces are bound to one BC with the other BC in a clamp with iron. Some Indonesians find it difficult to access technology that facilitates their lives. These difficulties lead to low community participation in controlling environmental damage. Training becomes one of the effective alternatives in learning methods towards a community collectively. It is done to increase the community's capacity through the process of community development on an ongoing basis.
