INTRODUCTION
Making stamp pad ink can be easy or complicated. Ink has been made for ages and has been used to write or draw on from papyrus to parchment to paper. Many of the recipes for ink involve creating great quantities, the ingredients are becoming more difficult to obtain, and the time and effort involved is substantial. Nowadays, most stamp pad ink contains chemicals which can be harmful to the environment. Furthermore, production of stamp pad ink containing various chemical components continuously adds up to problematic atmospheric pollution. The prices of commercially available non-natural stamp pad ink continuously increase.
Background of the Study
The Pili is a shady tree with resinous wood that grows abundantly in selected provinces. Most of the pili trees grow wild rather than in plantations.
Pili nut, a product of a Pili tree, is a versatile nut used for a variety of products such as pili nut brittle, pili cake, roasted pili and many other Filipino delicacies. The pulp itself is also consumed as food by the Bicolanos, but the huge volume turnout of pulp cannot be fully utilized for home consumption such that pulps are made to rot, go to waste and serve only as crude fertilizer. This waste can be recycled to produce a stamp pad ink.
This study will investigate the potential of a stamp pad ink from pili pulp extract. It will determine if the experimental product is comparable to the control in terms of cost, effectiveness, and biodegradability.
Most of the Pili pulp is usually thrown away. However, it will be used to develop a cheaper biodegradable alternative to synthetic stamp pad ink and will reduce waste simultaneously.
Pili
The pili (Canarium ovatum) is a fruit-bearing endemic to the Philippines especially found in Bicol region of Luzon Island (Memphis in May, 2011). The pili tree is regarded as an organically grown tree. The average tree starts bearing fruits six to seven years after planting with an estimated average fruit yield of 1,000-2,000 fruits per tree. However, there are certain varieties that bear flower at three to four years after planting. Pili trees could grow and last for a century. It is estimated that an average tree produces 33 kilograms of pili nuts in one year (Narra Nation, 2011). Because all of its parts have huge use for man, the pili tree is fast gaining fame as the “tree of life”, next to the coconut tree (DENR, 2013). Pili Tree is also known as a “stress tree”, that is, the more it is shaken and beaten by storms, the more it blooms and bears better fruit (Memphis in May, 2011).
The pili fruit is a drupe, 4-7 centimeter long, 2.3-3.8 centimeter in diameter and has a weight of 15.7-45.7 grams. The skin is smooth, thin, shiny, and turns purplish black when the fruit ripens. The pulp is fibrous, fleshy, and greenish yellow with a pointed shape-end hard thick shell. Within the shell is an embryo seed with thin brownish fibrous coating (Narra Nation, 2011).
The pulp of the Pili fruit is eaten as a vegetable. Blanched in hot water for about three minutes, it is perfect for salads, or simply dipped in fish sauce for that tangy kick (Memphis in May, 2011). Boiled pili pulp resembles the sweet potato in texture and is considered to have food value similar to that of avocado (DENR, 2013).
Statement of the Problem
This study will be performed to test the feasibility of Pili (Canarium ovatum) Pulp
Extract as an Effective Alternative Stamp Pad Ink. It aims to answer the following:
1. Is Pili (Canarium ovatum) Pulp Extract an effective alternative stamp pad ink?
2. Is Pili (Canarium ovatum) Pulp Extract a cheaper option as a core ingredient of stamp pad inks?
Statement of the Hypothesis

This study will be performed to test the efficiency and feasibility of the most common plant in Bicol, which is Pili (Canarium ovatum) .It will aim to find the possible use of Pili pulps. This study may lead the way on further experimentation on Pili as alternative ingredient to many productions. This study will be expecting for a positive outcome and good results. The researchers expect the following:
1. Pili (Canarium ovatum) Pulp Extract is an effective alternative stamp pad ink.
2. Pili (Canarium ovatum) Pulp Extract is a cheaper option as a core ingredient of stamp pad inks.
Significance of the Study Pili is a native fruit commonly found in Bicol region. It can be bought from the market with low cost. Production of ink by the use of this fruit is a solution to different problems rising in the community. Stamp Pad Inks are used on stamp pads, and stamp pads are used in the variety fields of life. It may be used in education; teachers use stamp pads for their signatures, even students uses this for marking, in medicine; doctors use stamp pads for marking their name on a prescription pad, in business; for marking receipts of the day-to-day business transaction, and most importantly for forensic science; CSIs’ use this for the thumb mark used as DNA identification. Therefore it is necessary to produce an effective alternative stamp pad ink, which involves the use of pili, that may make certain tasks easier for human. Some inks use expensive material which results to the high retail price. The researchers conclude that inks produced by using native fruits such as pili are possible solutions to the financial problem of many people. The process of making pili inks will not require a very long process. The consumers will get to purchase a cheaper ink but with the same quality as those of imported inks.
Scope and Limitations The study is to conducted at a local home here in Sorsogon City Philippines from July 2013 until March 2013 in order for the researchers to gather sufficient evidence and meet the objectives of the study. The study focuses only on making an effective alternative stamp pad ink.

Materials
Preparing the Pili Pulp Extract:
1. 3-4 cups of Pili, ½ cup liquid yield
2. Blender
3. Juicer
4. ½ tsp. salt
5. ½ tsp. vinegar
6. Glass jar
7. Metal or Wooden Spoon
8. Glass or ceramic bowl

PROCEDURES
Stamp Pad Ink
Preparing the Pili Pulp Extract
Purchase or harvest your pilis. Make a Pili pulp extract by peeling the pilis and separting the pulp from the flesh. Mash the pili pulps or have it on a juicer. Put a fine-mesh strainer inside a bowl or balance a smaller strainer on the rim of a bowl. When using a juicer, it is unnecessary to have a strainer since the resulted extract of the juicer is already strained. Press the pili pulp against the sides of the strainer with a spoon. When using a wooden spoon, it may become stained permanently. Don 't try to drain the fruit of all its juice. Forcing the juice from the skins of the results in cloudiness, affecting the final product. Remove strainer and discard fruit pulp or set aside the pulp for another use.
Preparing the Pili Pulp Ink
Mix the vinegar and salt into the pili pulp extract. Vinegar and salt clarify and deepen the color of natural dye and ink products, as well as preserve the juice from spoilage. Pour the pili pulp ink into a small, wide-mouthed jar. Recycled and cleaned 2 oz. baby food jars or specialty jam jars are ideal.
