Vol 1, No 1 (2012): E-Jurnal Agroindusri Indonesia ABSTRACT Production scheduling is an important aspect to support the success of a manufacturing company in achieving the target of production planning and affects the implementation of the production process over a period of time. The amount of idle time in scheduling are considered less effective in the production line and detailed production scheduling becomes a problem to be solved with rearrangment of the daily activities in PT. MDS. Modeling proper scheduling is a means to help develop the daily production schedule. Preliminary research results indicate that modeling of production scheduling in PT. MDS are influenced by demand  of products, stock products, number of production, downtime of machine cause of change over time, the order of production  scheduling, transportation delay between machines, and working time of machine. The selection of the method of calculation in the preparation of scheduling models must be adapted to the conditions preliminary research to give solutions of  scheduling problems in PT. MDS. A  Critical ratio method, the next grouping of products, and  re-sequencing of production process with Shortest Processing Time method is the right method to re-sequencing of scheduling models in response to a scheduling problem in PT. MDS. A Critical ratio method is useful to sort the product type, while the grouping of products and the Shortest Processing Time method useful to maximize the use of equipments as well as reducing of idle time. The results showed a decreased machine utilization of 64% to 60% and downtime of machine decreased to 5%.                                                                                                                Key words : utilization of machine, idle time, production sequence, critical ratio, shortest processing time,               productivity Abstract   PDF

Vol 1, No 1 (2012): E-Jurnal Agroindusri Indonesia ABSTRACT  The cake of jatropha seed as by product generated from in situ transesterification process contains high protein (34,68%) and it is not yet optimally benefited. In this research, the cake of jatropha seed was benefited to produce binderless particle board. The purpose of this research is to produce the particle board from the cake of jatropha seed generated by in situ transesterification process with protein as natural binder. The particle board production was carried out under the following process condition : jatropha seed cake moisture content (10- 20%), pressing temperature (140-180oC) and pressing duration (8-12 min). The phisycal and mechanical properties of particle board were tested according to JIS A 5908:2003. Jatropha seed cake moisture content, pressing temperature and pressing duration affected the phisycal and mechanical properties of particle board. The density and moisture content of particle board were respectively 0,79-0,91 g/cm3 and 7,07-10,06%. The swelling in water and water absorpsion after 24 hour water soaking were respectively 14,88-30,60% and 51,67-82,93%, and they were not accordance with JIS A 5908:2003. Modulus of Rupture (MOR) and Modulus of Elasticity (MOE) of particle board were not also accordance with JIS A 5908:2003. Their value respectively were 20,04-65,99 kgf/cm2 and 2340,90-5150,25 kgf/cm2. Generally, the phisycal and mechanical properties of particle board were not accordance with JIS A 5908:2003 except for density and moisture content. Keywords : cake of jatropha seed, particle board, in situ transesterification Abstract   PDF

Vol 1, No 2 (2012): E-Jurnal Agroindustri Indonesia ABSTRACT   The increasing of human demand about diesel fuel that was not balanced with the appropriate of petroleum production caused global crisis of energy. Under these conditions, biodiesel is a promising alternative fuel to replace petroleum-based diesel. Jatropha curcas L. can be used as an alternative energy resource because it contains 30-40% oils. Jatropha curcas L. is a plant that can be easily growned in Indonesia, so it is prospective as raw material for biodiesel. The purpose of this study was to determine the influence of reaction time and hexane to total solvent ratio on biodiesel yield and quality produced by in situ transesterification of jatropha seeds. The used raw material was grounded jatropha seeds with moisture content of < 2% and ± 20 mesh size. The operating conditions of hexane to total solvent ratio and reaction time were varied at 1/6, 2/6, 3/6 and 3, 4, 5 h, respectively. KOH concentration, reaction temperature and stirring speed were fixed at 0.075 mol/L methanol, 55oC and 300 rpm. The analysis of biodiesel quality included acid value, viscosity, ash content and saponification value. The results were analyzed with Response Surface Method (RSM). The produced biodiesel yield was 71%-81%. The highest yield (80.67%) and the best quality of biodiesel were obtained under operation condition of the 5 h reaction time and 1/6 hexane to total solvent ratio (acid value of  0.31 mg KOH/g, saponification value of 193.97 mg KOH/g, viscosity of 3.45 cSt, and ash content of 0%). Respon surface analysis of hexane to total solvent ratio and reaction time variables to respon of biodiesel yield resulted first order equation, Y =  63.00– 4.14(A) + 3.81(B), with R2= 95.56%. The variable of reaction time (B) had significant influence on biodiesel yield. Respon surface analysis of operating condition variables to respon of biodiesel quality showed the variable of hexane to solvent ratio (A) and reaction time (B) had significant influence on acid value and viscosity, especially.   Keywords: biodiesel, jatropha, in situ transesterification, reaction time, solvent ratio  Abstract   PDF

ABSTRACT

 

Productivity improvement is an essential effort  to achieve the optimal utilization of the resoures, particularly in production on the assembly line  of soy sauce (soy filling) in  PT X.  The productivity improvement is based on measuring the OEE (Overall Equipment Effectiveness). OEE is a measurement methods of the production machine effectiveness that involves measurement of the availability rate, performance rate, and quality rate. Through measurement of OEE​​, the potential equipment utilization, identify bottlenecks and track the lossess were monitored. Results of the OEE measurement on assembly line in PT. X indicate a lower level  than optimal results so that the improvement is required  to improve the competitiveness of enterprises. A quantitative model of Particle Swarm Optimization (PSO)  was  ​​modified to improve the productivity and to reduce the productivity cost.

 

Keywords: productivity improvement, lean production, OEE, Particle Swarm Optimization
