Abstract

Non-destructive testing based on sound wave propagation has been used widely to estimate wood quality of standing trees. The aim of this study was to evaluate the characteristics of the sound wave velocity in relation to pine resin productivity and resin intercellular frequency and diameter. The samples were 72 trees consisted of 36 trees which were tapped by the quarre method and 36 other trees were tapped with addition of stimulants. The speed of sound waves propagation was measured by SylvatestDuo for radial direction and longitudinal. The tapping position was determined refering to the wind direction. The resin productivity was twice for tapping with stimulant comparing to the control. The highest resin productivity was 87.31 g per harvest for tapping with stimulant and the lowest (39.86 g per harvest) for control. Statistically, there was not significant difference in sound speed for tapped position as well as for measurement before and after tapped of both radial and longitudinal testing, as well as for the anatomical properties of both of treatments. A high positive correlation was found between resin productivity and intercellular frequency for both treatments (r>0.80), however, there was not significance correlation between resin productivity and other parameters.Keywords: Pinus merkusii, resin tapping, sound wave propagation

Abstract

Sudajaya Girang Village has potential in developing the agricultural sector, however, in this case still a need for activities that support the development of local village potential through mapping the local potential of the village and through SUJI activities (Socialization of the Kampung Flori Initiation Efforts) and GERBERA (Movement for Learning About Nature) which held at the local elementary and middle school. The purpose of this activity is to help the people of the village of Sudajaya Girang in mapping the local potential of the village and training in making vertical gardens, besides this activity also socializes the importance of protecting the environment for elementary and junior high school students. Visualization of the potential of Sudajaya Girang Village in RW 03 and RW 04 regarding the location of gardens, cultivation fields and centers of cut flower crafts and ornamental plants. The method used interviews, socialization, practice and also maping locations using GPS. Based on the interview survey that has been done shows that the enthusiasm of the community is high regarding the development of farmer groups, but not yet supported by adequate human resources, so there is a need for further programs to help prepare resources community power in starting entrepreneurship in the field of flori. The success of the socialization activities to elementary and junior high school students related to the importance of protecting the environment can be seen from the enthusiasm of the students in participating in a range of programs such as getting to know the typical flora and fauna types of the village, as well as being able to sustainably utilize the typical flora of the village for making a herbarium which in the future is expected to become learning activities for entrepreneur. Keywords: : Cut flowers, suji plants, stringing flower
