Coco fiber and mahogany can be used as raw material for the manufacture of particle board. Quality of particle board was affected by several things. One of them was affected by particle’s composition and adhesive levels. The aim of this research was to evalated the affect of particle’s composition and adhesive levels, and also to find the best treatment. The dimension of sample test was 25x25x1 cm with a density target of 0.7 g/cm3. The composition between coco fiber and mahogany were 60:40, 70:30 and 80:20. The adhesive used were phenol formaldehyde with composition of 10%, 12.5% and 15%. Testing the quality of particle board refers to the standard JIS A 5908-2003. The results showed that some of the test on particle board not fulfiled the standards of JIS A 5908-2003, such asMOE and MOR. However, all of density test on particle board had fulfilled the standard. Moisture content test on particle board compositionof 80:20andadhesive content of 12.5% had fulfilled the standard. Thickness swelling test on particle board compositionof 60:40and adhesive content of 15% had fulfilled the standard. And also internal bond test on particle board compositionof 60:40 and 70:30 with adhesive content of15% had fulfilled the standard. The best treatment of this research were a particle board made from compostion of 60:40 and adhesive content of 15%.

One way to approve laminated board quality of palm oil trunk was soaked the laminated board with phenol formaldehyda (PF). The purpose of this study was to evaluate the influence soaking time variation and concentration PF than to determine the best treatment in this research. Laminated board was consisted 3 (three) layers with size 45 cm (length) x 7 cm (width) x 3 cm (thick). The variation of these research were soaking time (10 minutes, 2 hours, and 24 hours) and PF concentration (5.10.15. and 20% ). These study used random experimental factorial design and the results were compared with JAS 243:2003 standard. Results showed weight gain value, density, moisture content, water absorption 2 hours and 24 hours, thickness swelling on immersion 2 hours and 24 hours, thickness swelling on immersion 2 hours and 24 hours around, delamination test, modulus of rupture, and modulus of elasticity. Result showed that 3.82-15%, 0.39-0.47 g/cm3, 11.66-14.16%, 36.15-46.38%, and 78.87-98.65%, 2.5-11.58% and 5.13-17.58, 0%, 170.23-250.15 kg/cm2, and 17224-43767 kg/cm2. Moisture content and delamination values have fulfilled JAS 243:2003 standard. The other hand, MOE and MOR values were not fulfilled yet.

The variation using for the urea formaldehyde adhesives and padding Styrofoam was 100 : 0 %, 90 :10%, 80 :20%, 70 : 30% and 60 :40 %. The boards were made with size 25 cm x 25 cm x 1 cm with density of 0,70% g/cm3. Particleboards using 10% and press 25 kg/cm2 by the padding Styrofoam. The temperatures was 1300 and the pressing times was 10 minute. Particleboards was tested for physical and mechanical properties.The results showed that although the density values ranged from 0.565 - 0.627 g/cm ³, the water content of 7.45 - 8.23 %, DSA 81.66 - 111.84%, PT 9.99 to 16.35% MOE 6419.87 - 8660.58 kg/cm2, MOR 53.638 - 81.167 kg/cm2 and IB 0.85 - 6.11 kg/cm2. Entire physical properties have fulfilled to SNI 03-2105-2006 standards. All the mechanical properties have not fulfilled to the standards except internal bond with SNI 03-2015-2006 100 treatment: 0 % and 90: 10 %.

Community service activity was conducted in July-October 2021. The main event was held on September 4, 2021, and attended by around 33 participants divided into two sessions due to the Implementation of Community Activity Restrictions (PPKM). The core activity begins with explaining the history and understanding of hydroponics, the advantages of hydroponics, planting media and potting media, types of hydroponics, stages of hydroponic vegetable cultivation, manufacture of vegetable pesticides, and harvesting. The direct practice of the activity begins with cutting Rockwool, media preparation, and sowing mustard and kale seeds. Transplanting do when the seedlings are 7-10 days old, and after three weeks of transplanting, we can do the harvesting. Each participant filled out a questionnaire for the evaluation. Based on the questionnaire review, most participants had heard of the hydroponic system but had never received the training. Furthermore, after receiving this training, most participants understood the hydroponic system and tended to agree that hydroponic plant cultivation is easy to do and can be a business opportunity. Meanwhile, in terms of costs, participants tend to state that hydroponic systems require high costs.
