3. To determine the economic viability of the machine
![Page 11: Tiger Grass Pollen Remover Con Wood Working Machine-IRCHE](https://reader036.fdocuments.net/reader036/viewer/2022081421/55cf99b2550346d0339eb4c9/html5/thumbnails/11.jpg)
Rationale
• Two municipalities in the province of Romblon are known to be the major producers of tiger grass (luway)
• 400 hectares were planted with tiger grass with more farms being established each year for the past three years (DOST-PSTC-Romblon)
![Page 12: Tiger Grass Pollen Remover Con Wood Working Machine-IRCHE](https://reader036.fdocuments.net/reader036/viewer/2022081421/55cf99b2550346d0339eb4c9/html5/thumbnails/12.jpg)
Rationale
• In Dona Juana, San Agustin, Romblon, 400 farmers are engaged in tiger grass farming and the annual value of harvest is estimated to be 4 Million pesos.
![Page 13: Tiger Grass Pollen Remover Con Wood Working Machine-IRCHE](https://reader036.fdocuments.net/reader036/viewer/2022081421/55cf99b2550346d0339eb4c9/html5/thumbnails/13.jpg)
Rationale
• In Marigondon Norte, San Andres, Romblon, a study conducted to 100 farmers revealed that the annual income per farmer ranges from P2,500 – P150,00 depending on the size of the farm (Fetalvero, et. al.)
![Page 14: Tiger Grass Pollen Remover Con Wood Working Machine-IRCHE](https://reader036.fdocuments.net/reader036/viewer/2022081421/55cf99b2550346d0339eb4c9/html5/thumbnails/14.jpg)
Rationale
• 86 of the farmers get their income mainly in tiger grass farming alone and the remaining 14 are farmer – processor
![Page 15: Tiger Grass Pollen Remover Con Wood Working Machine-IRCHE](https://reader036.fdocuments.net/reader036/viewer/2022081421/55cf99b2550346d0339eb4c9/html5/thumbnails/15.jpg)
Rationale
• Most of the dried luway produced are sold to wholesalers and agents in different municipalities in the province and nearby provinces like Mindoro.
![Page 16: Tiger Grass Pollen Remover Con Wood Working Machine-IRCHE](https://reader036.fdocuments.net/reader036/viewer/2022081421/55cf99b2550346d0339eb4c9/html5/thumbnails/16.jpg)
Rationale• the traditional way of removing
tiger grass pollen is by striking and shaking manually and it took 10-15 minutes per bundle.
• The traditional way pause hazard to the constituent especially the children since pollen is being flown by wind
![Page 17: Tiger Grass Pollen Remover Con Wood Working Machine-IRCHE](https://reader036.fdocuments.net/reader036/viewer/2022081421/55cf99b2550346d0339eb4c9/html5/thumbnails/17.jpg)
Rationale
• Manual cleaning needs manual power and women can’t do it the way man can.
• Manual cleaning also cause damages to the stalk
![Page 18: Tiger Grass Pollen Remover Con Wood Working Machine-IRCHE](https://reader036.fdocuments.net/reader036/viewer/2022081421/55cf99b2550346d0339eb4c9/html5/thumbnails/18.jpg)
Rationale
• According to a study the most common problem encountered by tiger grass farmers is the absence of modern tiger grass processing facilities
![Page 19: Tiger Grass Pollen Remover Con Wood Working Machine-IRCHE](https://reader036.fdocuments.net/reader036/viewer/2022081421/55cf99b2550346d0339eb4c9/html5/thumbnails/19.jpg)
Rationale
• The usual handle of the broom produced is made from the stalks of the tiger grass
• Some uses wood from tree branches but complained of the handle’s irregular shape which is not attractive to consumers
![Page 20: Tiger Grass Pollen Remover Con Wood Working Machine-IRCHE](https://reader036.fdocuments.net/reader036/viewer/2022081421/55cf99b2550346d0339eb4c9/html5/thumbnails/20.jpg)
Rationale
• Others used plastic rattan to cover the irregular shaped handle to be attractive but it also entails additional cost
![Page 21: Tiger Grass Pollen Remover Con Wood Working Machine-IRCHE](https://reader036.fdocuments.net/reader036/viewer/2022081421/55cf99b2550346d0339eb4c9/html5/thumbnails/21.jpg)
Rationale
• If processing will be extensive, the annual estimated income of 1 to 2 Million may be increased to 3.6 to 7. 3 Million pesos
![Page 22: Tiger Grass Pollen Remover Con Wood Working Machine-IRCHE](https://reader036.fdocuments.net/reader036/viewer/2022081421/55cf99b2550346d0339eb4c9/html5/thumbnails/22.jpg)
