<![CDATA[The concept of Production Planning and Control is closely related to logistics activities, including in determining the production of a product. Production planning and control aims to get a complete picture of how to plan and control production in the industry of each company, so that all costs can be reduced. Production planning, Rough Cut Capacity Planning (RCCP), Material Requirement Planning (MRP), Capacity Requirement Planning (CRP), and Line Balancing are some of the steps that need to be done in providing an overview of the production planning and control system at the "Tamiya" Company. Production planning results in the amount of "Tamiya" production in a certain period by considering SEE and the most appropriate production strategy that results in total costs. MPS validation considerations are the output of the RCCP calculation, a comparison of the ratio of the required capacity to the capacity of the company. The MRP stage reduces production due to material unavailability, the result is the best material scheduling based on the lot sizing method which provides the lowest cost. CRP generates Planned Input and Planned Output per work station to see the balance between load and capacity. Line Balancing functions to balance assignments through the Ranking Position Weight (RPW) and Presedence Diagram methods, getting results in the form of updating the layout of the assignment so that the efficiency of the production line can be improved]]>

<![CDATA[Currently, the university is one of the actors in the use of chemical substances for educational purposes in practicums and research. Based on the survey, it is known that the processing of laboratory waste, especially organic wastewater, is not optimal. This needs to be considered considering that generally the university is located in the residential area so that if the wastewater pollutant, it will certainly risk causing serious impacts on the community. A wastewater treatment technology using photocatalysis can process toxic organic substances into simpler and environmentally friendly substances. This research includes several stages, namely the collection of waste organic compound from practicum and research activities, sampling of laboratory waste, and testing of waste treatment and analysis of the total content of organic compounds from permangnometric titration wastewater treatments. The results showed that the TiO2 photocatalyst with a composition of 0.8% (w / v) was able to reduce the content of organic compounds in the waste sample by 96.19027% in the reaction time of 4 days.]]>

<![CDATA[The study of thermal energy produced by the Sulzer ZAV 40S diesel engine using Marine Fuel Oil (MFO) can affect the engine combustion process because of the change in fuel chemical energy into internal work. The heat energy generated in the diesel engine where the ignition process when the piston approaches the dead point is then followed by the presence of fuel, namely MFO. The fuel will be sprayed through the nozzles into the combustion chamber. This will result in a complete combustion process where the composition of the mass of air and fuel in the cylinder will generate heat due to the high temperature. The results of the calculation that the need for fuel and air to produce the energy value (Q) of this diesel engine is 808.33 Kcal and the power (Ni) is 4,602.09 PK in every second while the mass of MGO is 5 Kg and air is 130 Kg in every minutes for continuous rotation of 500 rpm.]]>

<![CDATA[discoloration is the result of the action of endogenous polyphenol oxidase (enzymatic browning) followed by spontaneous polymerization of quinonoid compounds with other food components. Currently, the use of sulfite agents is the most widely used chemical approach to control browning of foods. However, consumer awareness of the risks associated with sulfites and growing regulations make sulfites an alternative. Efforts should be made to reduce the degree of browning of porang tuber chips caused by enzymatic non-enzymatic browning. The purpose of this study was to study the alternative use of sulfite as an anti-browning agent against the whiteness value of porang tuber chips. The alternative type of sulfite used is ascorbic acid. Ascorbic acid concentration (2, 5 and 7.5%) and immersion time (30, 60, 90, 120, 150 and 180 minutes) were selected as independent variables. The best condition for preventing browning of porang tuber chips was obtained by using 5% ascorbic acid at a time of soaking for 180 minutes and obtained the highest whiteness value (79.41). Keywords: anti-browning agents, lightness, chips porang]]>

<![CDATA[The high level failure is a problem that company always to minimized and to improve quality of final products, and also were conducted by PT. EDS Manufacturing Indonesia (PEMI) which is consistent in producting a quality product. PT. EDS Manufacturing Indonesia (PEMI) manufacture Toyota HI-ACE carline product for motorcycle. Therefore the high level failure in this product is unacceptable because it can harm or kill company, then to solve this problem we propose to use Failure Mode and Effect Analysis (FMEA) method and Fault Tree Analysis (FTA). Our research using the FMEA method at PT. EDS Manufacturing Indonesia for Toyota HI-ACE carline product shows the existence of various modes of failure in the production and quality assurance areas. The FMEA method give suggestions for improvements to the 2 failure modes to be priority based on the highest RPN value that is wrong dimension and demage insulation. The next step is identify the risks that contribute to failure with using the Fault Tree Analysis (FTA). With FMEA we found the highest RPN value that show highest defect such as damage insulation 324 or 14.78% and wrong dimension 280 or 12.77%. Keywords: failure mode, risk analysis, FMEA, FTA, RPN Value]]>

<![CDATA[The poor setting out of coastal settlements had very high vulnerability of the fire hazard. The limited access caused difficulties in evacuating the community (agents) when fire was accured. The communities as agents in a group interaction activities due to the environment had evacuation path and other support systems to find the fastest way out. This research had designed a simulation model of community movement during a fire disaster in the coastal settlement. The case study of this research was defined in the dense coastal settlement area of Pasar Batu Tarakan, North Kalimantan. The community evacuation simulation used the Agent Based Modeling (ABM) utilized NetLogo software. The survey was conducted by considering the condition of main route that can be accessed. The modeling had 3 simulation scenarios were based on the number of agents movement who left the fire site. The double linear regression had been utilized to analyze the variable correlation. The results showed a scenario 3 had the largest people number who passed out the exit way. The selection of the path was based on the distance and route width on the number of people save had very significant correlation (R2 = 98,34%).]]>
