<![CDATA[Pack carburizing is a method of thermo chemical treatment, when carbon dissolved in steel surfaces, revolve 0.3% - 0.9% with temperature between 825 oC - 925 oC, and keep it at several time and then continued with quenching process using water, oil, air or salt. This research had arranged to test the hardness of low carbon steel (ST-42) with 40% of BaCO3, and 60% of Carbon, before and after carburizing process in 3 type of holding time: 15, 30, and 50 minutes. Based on results, the best combination to reach a higher value of hardness provides by combination of after carburizing process and 50 minutes of holding time. Later, an extensive experiment by 2 hours of burning had shown an increase level of hardness up to 365% from the initial condition which proves the quality of this best treatment combination.]]>

<![CDATA[Even ERP systems success was modeled with considering for various aspects; the contribution of contingency factors has not been had a well-structure. Investigation by Ifinedo (2007) introduced a new relation model between organization characteristics (contingency factor) and ERP systems success by moderating of IT organizational factors (IT assets dan IT resources). This model involves only 3 characteristics, namely size, structure and culture of organization. Referred to the reference study on number of pre-related researches, there are connections between all organization characteristics (size, structure, culture, strategies and environment of organization) and ERP systems success by moderating of IT organizational factors. Our research provides a theoretical review to develop an ERP systems success and cross-relational hypothesizes of variables according to previous researches.]]>

<![CDATA[Number of pearl shell craft industry in Ambon city until the year 2010 were 60 groups with a wide market share. But until now they do not have good references about the standardization of production processes and product standardization, one of which is occupational health and safety (OHS). The lack of standardization causes business owners paying less attention to environmental conditions and facility business. The problem that arises is that workers tend to work without sufficient knowledge, outside of the procedure and denied the use of personal protective equipment (PPE). These things cause the worker at risk of disruption, accidents and illnesses arising from working conditions. Socialization of the OHS and the use of PPE, the provision of PPE and occupational health facilities, and training on OHS and the use of PPE is the solution for problems occupational accidents in the creative industry of crafts pearl oysters in the city of Ambon]]>

<![CDATA[The inner tube made a couple of turns inside the shell to increase the heat transfer area, thus the rate of heat transfer. The first, the entire heat exchanger was selected as control volume, Q became zero, since the boundary for this case lay just beneath the insulation and little or no heat crossed the boundary, The second, one of the fluids was selected as the control volume, then heat would crossed this boundary as it flew from one fluid to other and Q would not be zero. Refrigerant -12 was to be cooled by water in a condenser. The refrigerant entered the condenser with a mass flew rate of 5,5 kg/min at 0,9 MPa and variety of temperature 600 - 80 0C and leaved at variety 250 - 45 0C. The cooling water entered the condenser at 295 kPa and variety of temperature 50 - 25 0C and leaved at variety 150 - 35 0 C. The mass flew rate of the cooling water requireded was variety 20.9 - 20.31 kg/min ( decreased ). The heat transfer rate from the refrigerant to water was variety of 878 - 848,75 kJ/min ( decreased ).]]>

<![CDATA[S-35 C, is a low steel carbon type with 0,30% - 0,35% carbon composition, which has a low hardness. This matter can be overcome by changing the hardness of this steel through heat treatment process. Heat treatment method used in this experiment is pack carburizing method. Experiment results showed that with composition of 500 g of carbon and 0% beef bones with 15 minutes holding time, the hardness number increased as much as 116.90 HRC, there was 20.54 HRC number increased. With 10% of cow bones composition, hardness number became 118.39 HRC and 20.40 HRC number increased. HRC number became 122.20 and increased by 24.38 on 20% composition, and on 30% the hardness value became 130.36 HRC, increased until 32.05 HRC number. 40% composition showed increasing hardness number up to 133.34 HRC, with 35.08 HRC increased. And 50% composition showed 141.29 HRC number, increased until 43.95 HRC. 50% composition produce the highest increase of hardness number, this verified that the higher composition of cow bones makes higher increasing of hardness number in a heat treatment process deliver a harder steel, and also prove that beef bones can be used as a catalyst in pack carburizing process.]]>

<![CDATA[This research studies to know monoxide carbon content at gasoline engine and diesel with revolution of the same engine. Assaying is done by using exhaust emission of gas test device to know monoxide carbon content at diesel engine Yanmar L-40 and gasoline engine endure XL. From result of assaying indicates that ever greater of revolution hence carbon content increasingly increases. At gasoline engine and addition diesel of fuel does not influence increase of percentage of monoxide carbon but at increase of revolution of this engine has been formed monoxide carbon. This thing because of existence of domination Fuel in combustion chamber so that partly fuel is not combustible causes the forming of monoxide carbon at exhaust gas. ever greater of efficiency thermal hence monoxide carbon grade increasingly increases. Thereby Monoxide carbon yielded by Diesel Engine exhaust gas Yanmar L 40 slimmer while at gasoline engine Enduro XL carbon monoxide yielded quite a lot.]]>
