**3. Scope**

1.Scope of the Procedural Development from the Remaining Rice Stubble as a Wood Substitute Material

This would have the objective to develop the transformation procedure of remaining rice stubble in the cultivation areas of the North-eastern region.

The population of agriculturists cultivating the fields in the North-eastern region is 3,741,346 people [7].

The group sampling consisted of 100 agriculturists of the North-eastern region with the level of discrepancy being 100% by using stratified random sampling that divided the cultivation areas of each province in Thailand [8].

A structured questionnaire with a checklist of a five-point Likert scale to rate the levels of satisfaction in the transformation procedure for the newly developed rice stubble was used as the research tool [9]. Additionally, this used the statistical value from the confidence value of 10 group samplings with the value of Cronbach's alpha at a level of 0.873 by using the data analysis of the statistical descriptive value; such as, the mean, standard deviation (S.D.), and one way or single factor ANOVA [10].

2. Scope of the Production of Furniture Products for Children from the Remaining Rice Stubble and Predicting the Solution with the Customer Groups' Requirements That Affected the New Products

This aimed to present the designing procedure for the furniture products by using wood substitute material from rice stubble to be an invention of the communities for producing small industries inside the households.

The population comprised 9,183 customers interested in furniture who visited the product booths in the Furniture and Electronic Fair 2018 in Khon Kaen province, Thailand. Stratified random sampling was used to find 100 people as the discrepancy level of 100% [8].

A structured questionnaire with a checklist of a five-point Likert scale to rate the level of satisfaction of newly developed rice stubble furniture that utilized wood substitute material was used as the research tool [9]. This used the statistical value from the confidence value of 10 group samplings with the value of Cronbach's alpha at a level of 0.786 by using data analysis of the statistical descriptive value; such as, the mean, standard deviation (S.D), and dependent t-test [10].
