Abstract
The study aimed to analyses respond on metabolic rate glycogen deposit and morphological development of brown marbled grouper juvenile reared in different feeding frequency. The result of study provides new information on feeding frequency in the rearing technique of brown marbled grouper juvenile.
The study was conducted from September 2006 until August 2007 in Laboratory of Nutrition, Centre for Bracckishwater Aquaculture Ddevelopment, Takalar, Laboratory of Aquatic Animal Physiology, Faculty of Marine Scienses and Fisheries Hasanuddin University and Laboratory of Physiology, Faculty of Animal Medicine, Bogor Agricultural University. The study was conducted in randomized completed design, 3 x 3 with the treatment of feeding frequencies (A) two times per day, (B) four times per day and (C) six times per day.
The result of the study showed that study showed that feeding frequency significantly affects the metabolic rate and glycogen deposit of brown marbled grouper reared from 20 to 50 days old juvenile. Based on the metabolic rate performance, feeding frequency decreased as the juvenile age increased. Feeding frequency of 6 times daily was suitable for 21-27 days old juvenile, 4 times daily for 28-34 old juvenile and 2 time daily for more than 34 days old juvenile. However, feeding frequency significantly affects on glucogen deposit on up to the age of 25 days juvenile. Morphological development and melanophora pattern were not affected by the different feeding frequency. Based on the observation of morphological development and glycogen deposit, feeding frequency twice daily was enough for the growing of brown marbled grouper juvenile.

Synergies of Buginese community local wisdon in the implementation of public policy in Sidenreng Rappang regency
ABSTRACT
The aim of the study was to discover an effective and efficient concept and strategy in improving the quality of bureaucrats in the formation of bureaucratic behavior as a spear head of administration and social affairs to be able to carry out their duties and responsibilities as public servers and executors of public policy.
The study was descriptive qualitative and quantitative. The unit or analysis was bureacrats as public severs . The region samples were selected by quota sampling and respondents by purposive sampling. The data were collected through quetionare and interview and analyzed by using percentage, product moment, and multiple regression.
The results of the study indicate that principally the implementation of public policy is something prone to administration stucture and social affairs due to misperception of bureaucrats to their tasks and authorities who view it as something scared and an opportunity for personal or group interest. Therefor a significant reference is needed in realizing the management of good governance based on the principles of transparency, accountability, public participation, and law enforcement by synergizing local wisdom of Buginese community in the implementation of public policy as the main reference in structuring the life of the nation. This is due to lack of understanding on wisdom values of Buginese community and lack of implemantation which is assumed to have been irrelevant and marginalized. This has an impact on various aspects in the structure of government especially in the implementation stage of public policy namely ignoring officials competence, not enough transparency, unaccountable recruitment system, and environmental situation in which the politic is the reference. In order to make the implementation model of public policy efficient and effective in the future, it must be done by applying the local wisdom of Buginese community in the concept of appropriateness in each stage of public policy implementation.

Bruxism
Abstract
This paper review of bruxism phenomenon that refers to the grainding or cleanching of the teeth during awake or night sleep. The prevalence of bruxism decreases with age from 14% to 18% in childhood, 8% of adult population and 3% in the eldery. According to the existing literature, two groups of proposed etiological factors can be distinguished: peripheral (morphological) and central (pathophysiological and pshychological). At present, the bruxism is more often thought to be regulated centrally, not peripherally. Signs and symptoms of bruxism such as tooth wear/dental attrision, abfractions, orofacial pain, change of periodontal ligament, mobility, tooth sensitivity, fractured teeth and fillings, earache, headache, tightness of jaw muscle, chewed tissue on the inside of your cheek, impact on yhe esthetic appearance of a smile. There have been many clinical approaches to the treatment of bruxism. These can be categorized as acute, preventive and chronic management of bruxism, based on patien's signs and symptoms. In the case of acute symptomps with patient's experiencing pain, pharmacotherapeutics may be required. Meanwhile, if tooth wear is present an occlusal splint and stress management are recommended. Dentists and health professionals should be aware of the phenomenon of bruxism.
Key words : bruxism, signs and symptoms, etiology, occlusal splint/night guard.

The influence of acid concentration in soft drink on mineral tooth dissolving
Abstract
Demineralization or mineral tooth dissolving can occour if the tooth are under 5.5 pH environtment. Currently, some soft drink under 5.5 pH have been consumpted in general society. The low pH contributes in demineralization because it increases the concentration of hydrogen and this ion will damage hydroxyapatite. The objective of this study was to evaluate the influence of acid concentration in soft drink on mineral tooth dissolving. Design of this study was quasee experiment, included 15 samples of tooth fragment that have been divided into 3 groups. Every sample has been measured for its weight before being immersed in soft drink, and be noted as pre test. Subsequently, Group I, was being immersed in soft drink that contains carbonate acid; Group II, in phosphate acid, and Group III, in the water (control). The measurement of sample weight was done after 24, 48, and 72 hours after immersing, and be noted as post-test. The results of the study shown that the samples that had been immersed in carbonate acid beverages lead to a greater mineral dissolving than phosphate acid and the water.

Effect ulee kareng aceh coffee on surface hardness of acrylic denture base
Abstract
Hardness of a denture base a patient charge associated with the habit of consuming foods and beverages most commonly consumed. Ulee Kareng coffee was very popular, especially in the areas of Aceh. It was kind of Robusta coffee which contains acidic properties : pH of water mixed (5 grams of coffe in 120 ml of water) before = 3.00 and after = 5.74. The purpose of this study was to determine the change of surface hardness of acrylic denture base after being immersed in Ulee Kareng coffee for 3 days. Twelve cylinder specimens ( 5 mm diameter and 2 mm thickness) were randomly distributed in two groups : control (immersion in distilled water) and experimental (immersion in Ulee Kareng coffee). Hardness was measured before and after immersion using Knoop Microhardness tester by Shimadzu. Data were analyzed statistically by Mann Whitney and Wilcoxon test. The results of the studied showed that there was a significant difference between groups. The surface hardness of acrylic denture base decreased after immersion for both group.

Alveolar ridge augmentation using distraction osteogenesis
Abstract
Augmentation of the alveolar ridge is widwly used in implant treatment to create predictable function and esthetics in area with inadequate bone volume. There are different ways to augment the alveolar ridge. Distraction osteogenesis is a new method in increasing the width of the ridge and preparing a sufficient bed for implant or prosthesis. Distraction osteogenesis result in formation of new bone between bone segments that separated gradually by incremental traction. Alveolar widening by distraction osteogenesis is an alternative method for reconstracting alveolar atropy that is similar to alveolar splint grafting but without the graft which is offers many anvantages over traditional technique. This paper is aimed to discuss considerations and technique alveolar ridge augmentation for preparing adequate bone volume before applying implant using distraction osteogenesis method.

PROPERTIES OF DENTAL MATERIALS 4
SOLUBILITY AND SORPTION
The solubility of materials in the mouth and the sorption (adsorption plus absorption) of oral fluids by the material are important criteria in their selection. Frequently, laboratory studies have have evaluated materials in distilled water. At times these studies gave results inconsistent with clinical obsevations becaused materials in the mouth are covered with plaque and therefore are exposed to various acids and organic materials. An example of the inconsistency is that zinc phosphate cements are considerably more soluble in the mouth than laboratory tests in water indicate. Also, the loss of zinc phosphate cements retaining a gold crown is a result of dissolution followed by and accompanied by disintegration. Nevertheless, laboratory tests usually rank materials correctly, so only the actual magnitude of the numbers should be taken with grain of salt.
Solubility and sorption are reported in two ways : (1) in weight percent of soluble or sorbed material, and (2) as the weight of dissolved or sorbed material per unit of surfaces area (e.g., miligram per square centimeter).
Absorption refers to the upteke of liquid by the bulk solid; for example, the equilibrium absorption of water by acrylic plastics is in the range of 2%. Adsorption indicates concentration of molecules at the surface of a solid or liquid, an example being the adsorption of components of saliva at the surface of tooth structure, or of a detergent adsorbed an the surface of a wax pattern.
