PREFACEI
"Society is the ultimate beneficiary of research". 'Ibis statement means that all the result of research activities should be equally distributed to all users and stakeholders. There are many tools to dissemmate research findings, and one of them is through a scientific conference. Its role as a media for researchers and users includes policy-makers to cooperate closely to understand specific needs, ensure relevance of topics, and lmprove communication, dissemination and implementation of the research recommendations makes scientific conference essential to any research agency.
The International Conference of Indonesia Forestry Researchers (IN1\FOR) was an endeavour of Porestr), Research and Development (FORDA), the Ministry of Forestry to acti\-ely imprm'e the (Iuality of Indonesian forestry research and publications as well as establish a robust scientific forum for Indonesia forestry professionals from research and development entities including government agencies, private sectors and universities, Its first event was conducted in 5-7 December 2011 in Bogor under the theme of "Strengthening Forest Science and Technology for Better Forestry Development".
This conference aimed to prm-ide mternational experience for Indonesia forestry researchers. and de\'elop forestry research and development activities in Indonesia. In regards to international t()restry research forum. the International l; nion of Forest Research Organizations (ILTRO) involved numerous Indonesian participants. Unfortunately, this impressive complicm' has fatled to be redeemed by numbers of accepted papers. This mainly due to lack of experit'nce in international conference mechamsm and less technical knO\vledge in preparing the drafts.
This proceeding is a documentation and publication of papers and posters presented in the conference. It comlst of 110 succesfully presented oral presentations, when 77 papers out of them have been selected to be sent to lUFRO fomm. I expect this publication could be distributed to all participants, mers, partners and other stakeholders throughout Indonesia.
In addition, I \v(lUld like to acknowledge all the authors of papers and posters contributed 111 this proceeding. The comments and review from the edltors towards the publishing of the proceeding arc also greatly appreciated. I am also grateful for the participants who had actively involved in the conference. Finally, I wish this proceeding and the conti.:rence could contnbute endless benefits to the society toward strengthening forest science and technology for better forestn' development.

ABSTRACT
Bark is a maJor by-product from the wood processing industries. Ilowever, the bark has not been intensively utilized. In this stud\" mahogany bark was im'estigated the potency as hypercholesterolemia-preventing agent in white rats. 'lbe thirty five male rats were divided into five groups with seven rats in each group. Rats in normal group were fed with standard rat feed. II\'percholesterolemlC rats (negative control group) were fed with cholesterol feed (0.86%) and propyl tiouracyl at a dose of 0.5 mg/kg body weight. LO\'astatin, a commercial drug, was administered to positive control rats at a dose of 0.286 mg/kg body weight together with cholesterol feed. Mahogany bark hot water extract were administered to the other rats groups at doses of 4.2 mg/kg and 21 mg/kg body weight as well as cholesterol feed. The experiment was carried out for eight consecuti\'e weeks. The total blood cholesterol concentrations were analyzed every two weeks by enzymatic cholesteroloxidase phenol amino phenazone method (U IOD-PAP) and spectrophotometer at 500 nm of wave length. The results showed that administration of cholesterol feed and propyl tiouracyl in hypercholesterolemic group has increased the total cholesterol concentration to reach 52.7%. \\::hile the mahogany bark extract at the dose of 21 mg/kg body weight could successfully reduce the increasing of total cholesterol level by 35.8% compared to lovastatin which reduced the increasing of total cholesterol level by :n.8o. Therefore, the mahogam" bark has a potential of a hypercholesterolemia-preventing agent.
Keywords: Mahogany bark, hypercholesterolemia-preventing agent, lovastatin, total blood cholesterol
1. INTRODUCTION
Cardiovascular disease is a leading cause of death 111 the worldwide. One of the disease risk factor is the level of cholesterol concentration in the blood above normal level which called h:"percholesterolemia. Foods that contain saturated fats and high cholesterol may increase blood cholesterol concentrations when consumed in excess. Another factor that is a genetic condition, obesity, age and the presence of estrogen in women (Grundy, 1991).
More widespread cases of cardiovascular disease among the general population lead to the increasing need of a cheap and effecti\'e drug. Medication of cardiovascular disease with herbal therapies has been developed as an alternati\'es to synthetic drugs. Therapy with herb has been developed in addition because it is cheaper, efficacious, and side effects can be avoided, as well as raw materials available in nature. In order to develop herbal medicines, high potentially mahogany bark \vas investigated its effectiveness as a supplement in the treatment of coronalT heart disease.
Previous study of mahogany bark showed three chemical compounds has been isolated and identified from the bark i.e. swietemacrophyllanin, catechin, and epicatechin (Falah et aI., 2(08). Those compounds have a high antioxidant activity and potentially prevent the oxidation of lowdensity lipoproteins (LDL) in the blood \'esse\' Therefore, it \vill inhibit the development of

atherosclerosis. that IS responsible for coronan~ heart disease. In this study, mahogany bark extract was investigated the potency as an antihypercholcsterolemia-preventing agent in white rats. The activity was compared to that of lovastatm as a reference.
2. EXPERIMENTAL METHODS.
2.1 Extract Preparation
Mahogany bark were collected from Sumedang. Indonesia. A dned bark powder of i'vfahogany (500 g) were boiled in two liters of \vater for four hours in hot water extraction method. 'rhe extract was then filtered and c\'aporated \\"ith a rotarY evaporator at and the crude extract was used in biological assay.
2.2 Animals
Male Sprague-Dawle\' rats of ,) weeks old \\Tre obtained from The National :\genC\" of Drug and Food Control of Indonesia. 'Ihe~~ \\Tre fed \\~ith a ~tandard laboratory diet and allowed food and water ad libitum for an acclimatization periods of 10 weeks prior to experiments. The animals were divided into five groups of seven each and housed individually during the experimental period.
2.3 Experimental Design
,\11 the rats crpr't{~ue dawiey albino male rats) \\Tre randomly di\'ided II1to the tive groups. Croup 1\: Normal (N) rats administered NaCl 0.90 b,' intraperitoneal and oralh~ alJuades I ml
daily. Group B: IIypercholesterolemia (11K) negative control rats were fed with cholesterol feed
(O.RGo/o) and propYl tiouracyl at a dose of O.S body \\Tight. Group C: LOYastatin (Lo\'as) positive control rats administered standard drug lovastatin (O.2R6
mg/kg, orally) daily together with cholesterol feed and propyl tiouracy!. Group D: Hypercholesterolemia rats (EI) administered hot water extract (4.2 mg/kg, oraIly) daily
together with cholesterol feed and propyl tiouracyL Croup E: Ilypercholcsterolemia rats (1':2) administered hot water extract (21 mg/kg. orally) daily
together with cholesterol feed and propyl tiouracyL The experiment was carried out for eight consecutive weeks. Cholesterol feed was
prepared from mixture of egg yolk, goat fat, 'Tgetable oil, and standard feed.
2.4 Measurement ofTotal Blood Cholesterol Level
mood samples were obtained from the tail "cin 111 fasting rats for IR h and blood cholesterolle\Tls were measured using an enzymatic method of cholesteroloxidase phenol amino phenazone (OIOD-PAP) with a commercial diagnostic kit (Randox). A 10 /-lL of blood semm was mixed with 1 mL of kit reagent. The solution was then shaken and kept stand for 10 min at room temperature to afford pink solution. Standard was measured as like the same way at different concentration levels (25, 50, 100, 200 and 250 mg/dL). Absorbance's of the samples were measured with spectrophotometer at 500 nm. In this study, analysis of blood cholesterol using blood semm was done over 5 times with each blood sampling at weeks-D, 2, 4, 6 and 8 of the experimental periods.
2.5 Statistical Analysis All the values of body weight and fasting blood sugar were expressed as mean standard
error of mean (S.E.M) and anah'zed for "-\NOVA and Duncan's I-test. Differences between groups were considered significant atp

3. RESULTS AND DISCUSSION
3.1 Body Weight
Body \\el~ht of the rats increased significantly during the experimental periods in each groups (hgure 1). However, the body weight is not statistically difference at the end of the periods. '\ormaJ rats group haH: a lo\,,-est body weight than that of another groups because of untecdi!1~ the cholesterol feed. Consumption of cholesterol feed can lead to increase the body weight of rats.

3.2 Blood Cholesterol Level
Administration of cholesterol-rich feed can also enhance the total of blood cholesterol leveL Consumption of foods rich in cholesterol and fatty acids will suppress the formation of LDL receptors, thus will increase cholesterol in the blood. .\dministration of PTU also can exhibit the Increasing of blood cholesterol level. It caused the PTl' as an antithyroid agent will inhibit the formation of thyroid hormone, but did not inhibit the secretion. 'lbyroid hormone deficiency may suppress the formation of LDJ, receptors in thc bver to trigger hypercholesterolemia. Administration of cholesterol feed and propyl tiouracyl In hypercholesterolemia group has increased the total cholesterol concentration to reach 52.7%
Statistically, blood cholesterol level of each the rats groups is not difference significantly at the beginning of experimental periods. Proftle of the blood cholesterol le\"els of the rats shown on Table 1.
