The aim of this activity was to training the manufacture of virgin coconut oil (VCO) with a without heating method to the community, especially the mother-housewife, resident of RT 12, Pematang Gubernur, Muara Bangkahulu, Bengkulu. As for the specific targets to be achieved in this activity was for the women, especially mothers, resident of RT 12 has the ability to produce VCO at least for their family, so that can improve the health and wellbeing of their family. The method used in achieving this goal was by lecture, discussion and practice of making VCO so that these activities target communities to be better understand the method of making VCO and can practice it theirself at home respectively
The aim of this research was to make particle board from coconut frond powder with various grain size. Particle board test pieces are made by mixing coconut frond powder with various grain sizes, namely 10; 25; 50 and 75 mesh with 40% of liquid rubber compound to obtain a particle board test pieces with the length, width and height of 5 x 10 x 7.5 cm and then dried in the sun. Then the particle board test pieces pressed to a thickness of 2.5 cm and then characterized its strength which includes the modulus of rupture (MOR), the modulus of elasticity (MOE), the Screw Hold Strength and water absorption. The results of this research indicated that the best strength of particle board was obtained on the use of 50 mesh coconut front powder and 40% liquid rubber compound as the adhesive. On this mix, the value of MOR, MOE, the strength of the screw and water absorption of resulting particle board are 1528.32 g/mm2, 618.18 g/mm2, 4.9111 N/cm2 and 26.87% respectively.
The effect of KOH stabilizer on mechanical and chemical properties of liquid rubber compound has been examined. Liquid rubber made by mixing stearic acid and zinc oxide as activator, 3,5-di-tert-butyl-4-hydroxy toluene and liquid smoke as antioxidant, CaCO3 as filler, dibenzothiazole disulfide and tetramethyl thiuram disulfide as accelerator, KOH as stabilizer and sulphur as vulcanizing agent with concentrated latex at room temperature, then maturated for 72 h. In this research the use of KOH stabilizer was varied as 3, 4, 5, 6 and 7 phr. Before being examined, rubber film made from liquid rubber compound by dyeing process then vulcanization done at 100 °C with water vapor. The rubber film which produced from liquid rubber compound then was characterized their mechanical and chemical properties such as resistance to heating, resistance to acid and alkaline resistance. The result showed that KOH content changed the mechanical and chemical properties of liquid rubber compound.
AbstrakTelah dilakukan pembuatan dan karakterisasi mekanik papan partikel berbasis cangkang buah karet dengan perekat limbah plastik polipropilen. Papan partikel dibuat dengan variasi berat serbuk cangkang buah karet masing-masing 50 gram, 100 gram dan 150 gram, dicetak dengan ukuran 28 cm × 12 cm × 4 cm. Campuran serbuk cangkang dan perekat selanjutnya dikempa menggunakan alat press sederhana selama 1 jam dalam keadaan panas, kemudian didiamkan selama 7 hari pada suhu kamar. Karakterisasi papan partikel meliputi pengujian sifat fisika dan sifat mekanik. Papan partikel yang terbuat dari limbah plastik polipropilena dan cangkang buah karet memiliki kerapatan 0,81 -0,88 g/cm 3 , kadar air 0,34 -0,93%, daya serap air 5,67 -10,69% dan tebal pengembangan 0,26 -1,62%. Hasil uji sifat mekanik papan partikel dari serbuk cangkang buah karet dan plastik polipropilena menunjukkan nilai keteguhan patah 53 -56,54 kgf/cm 2 , nilai keteguhan elastis 253,85 -400,87 kgf/cm 2 dan kuat cabut sekrup sebesar 1,96 kgf/cm 2 . Kata kunci: Cangkang buah karet, polipropilena, papan partikel, sifat fisika dan mekanik AbstractPreparation and characterization mechanical properties of particles board based shells fruit rubber use plastic of polypropylene waste as adhesive has been done. Preparation of the Particle board based shells fruit rubber and plastic of polypropylene addition with variation of 50, 100 and 150 grams. The Particle board was printed on the same size 28 cm × 12 cm × 4 cm. Blending of the internal shell powder and adhesive of polypropylene used a hot press for 1 hour, then settled for 7 days at room temperature. Characterization the particles board includes of the physics and mechanical properties. It is the density 0.81 -0.88 g/cm 3 , of the water content 0.34 -0.93%, water absorption 5.67 -10.69% and the thickness board expansion 0.26 -1.62%. The values of MOR and MOE of particle board was 53.00 -56.54 kgf/cm 2 , and 253.85 -400.87 kgf/cm 2 . The values of strong pull secrew was 1.96 kgf/cm 2 .
Virgin coconut oil (VCO) is coconut oil that contains medium chain fatty acids (MCFA) which are easily broken down by the body in very high amounts. Besides that, VCO also has very high antioxidant content such as tocopherol and beta-carotene. This PPM activity aims to provide VCO Making Training with the Enzymatic Method with pineapple fruit extract and fermentation with baker's yeast in the community of RT 12 RW 03 Pematang Governor Village, Muara Bangkahulu District, Bengkulu City. The activity began with a lecture followed by a discussion and practice of making VCO with enzymatic and fermentation methods. The results of observations in the field indicate that the target community of this PPM activity is very enthusiastic to take part in this activity because they feel they have gained additional new knowledge about how to make VCO which can complement their knowledge of the known VCO making technique, namely the fishing method. With the knowledge of making VCO taught in this activity, the target community will be able to have alternative methods for making VCO other than what has been known so far with easily obtained equipment.
