This research was to determine the physical and mechanical properties of particle board from acacia sawdust and sawn wood sawdust. The results of water content ranged from 6.85 to 9.22%, density ranged from 0.39 to 0.47 g / cm3, thickness development ranged from 2.21 to 7.04%, flexural strength (modulus of elasticity or MOE ) ranges between 1000.33 - 16127.48 kgf / cm² and the strength of the fracture (modulus of Rupture or MOR) ranges from 1.10 - 1.73 kgf / cm². MOE and MOR values and densities in treatment C that do not meet SNI 03-2105-2006 while in testing other treatments have meet SNI 03-2105-2006. The composition of raw materials has a very significant effect on the treatment of water content, density, thickness development and MOE. Physical and mechanical properties had no significant effect on the treatment of MOR values. The physical properties of particle board on average meet ISN 03-2105-2006. There are no mechanical properties that meet SNI 03-2105-2006.Keywords: Particle board; waste; polyester resin

Aims of the study is to identify phytochemical components (alkaloid, flavonoid, saponin, quinone, triterpenoid, and tannin) of 5 species growth in University of Lambung Mangkurat (ULM) Kawasan Hutan Dengan Tujuan Khusus (KHDTK = Education and Training Forest) area. These species are Madang Pirawas, Margatahan, Alaban Timbasu, Rawa Rawa Pipit, and Pulantan. Chemical analysis conducted in Wood Chemistry Laboratory, Faculty of Forestry ULM. The result shows that alkaloid component is found in Madang Pirawas, Margatahan, Alaban Timbasu, Rawa Rawa Pipit, and Pulantan’s leaves. Alaban Timbasu has more alkaloid than the others. Flavonoid component is found in Madang Pirawas, Margatahan, Rawa Rawa Pipit, and Pulantan’s leaves.Rawa Rawa Pipit has more flavonoid than the others. Saponin component is found in Madang Pirawas, Margatahan, Alaban Timbasu, Rawa Rawa Pipit, and Pulantan’s leaves. Pulantan has more saponin than the others. Quinone component is found in Madang Pirawas, Margatahan, Alaban Timbasu, Rawa Rawa Pipit, and Pulantan’s leaves. Madang Pirawas has more quinone than the others. Steroid component is found in Margatahan, Alaban Timbasu, and Rawa Rawa Pipit’s leaves. Alaban Timbasu has more steroid than the others.Triterpenoids component is found in Margatahan, Alaban Timbasu, and Rawa Rawa Pipit’s leaves. Alaban Timbasu has more triterpenoid than the others.Tannin component is found in Madang Pirawas, Margatahan, Rawa Rawa Pipit and Pulantan’s leaves. Rawa Rawa Pipit has more tannin than the others.

Objective: This study aimed to evaluate the effects of papaya (Carica papaya L.) male flower hexane fraction (PHF) on cell cycle of colon adenocarcinoma (WiDr) cell and its combination index (CI) with doxorubicin.Methods: Flow cytometer and the CI were used to show the PHF on cell cycle of colon adenocarcinoma (WiDr) cell and to calculate the synergism potential, respectively.Result: The result showed that the PHF giving inhibition on cell cycle of colon adenocarcinoma (WiDr) cell in G0-G1, S, G2-M phase. Furthermore, the combination of PHF with doxorubicin in colon adenocarcinoma (WiDr) cell gave a strong synergistic effect with optimal concentration of 8 μg/ml–50 nM (PHF-Doxorubicin) with the IC score lower than 1.Conclusion: This study provides evidence that PHF could be a new potential co-chemotherapeutic agent with doxorubicin on colon adenocarcinoma cell.
