[en] Control of the fuel-efficient plant operations are key to gamma irradiation service in MINTec-Sinagama. Without an efficient operation, irradiation services will be disrupted and lead to customer product failed to be completed in a set time. Additionally, downtime each time operation is also important to monitor to ensure that the fuel-efficient plant exceeded 85% in each month. In this paper MINTec plant operations data collection-Sinagama made during the year 2011-2015. Analysis carried out against downtime, the extent of damage and the action according to the classification of plant problems. This data collection is important for pattern characterization solution that can be made to the irradiator IR219, JS10000 in MINTec-Sinagama. (author)

[en] Full-text: Gamma irradiation operations require a qualified plant operator, irradiation engine and a good support system. Every plant operator on duty should undergo specialized training and verified at certain times. This paper is a certified operator experience sharing of gamma irradiation plants at MINTec-Sinagama. The engine used is irradiated IR219 engine with JS10000 transport system. This partnership is one of the knowledge management for gamma irradiation plant operators. (author)

[en] Before being subjected to gamma irradiation at MINTec-Sinagama, the product requires packaging (packaging) for packaging purposes. The packaging container must be in accordance with the irradiation objectives and the product itself. This paper is made to see the effects of gamma radiation on various types of container wrapping physically. The containers are petri dishes, glass bottles, paperboard boxes, plastic containers and plastic sacks. Dos 3.0 to 500 kGy is applied to the former wrapper. Dose options are based on the frequency of dosages requested by Sinagama customers. Physical tests apply to former packaging according to suitability after irradiation every 1 hour, 1 day up to 1 month. The collection of this data is important for the use of Sinagama customers.

[en] The first indication that the EPS3000 electron beam machine failed to produce electrons was observed via the display panel. Although high energy had been generated the beam current indicator remained zero. The potential source of problem could come from the motor-generator inside the power supply tank or electronic problem of transmitting the signal back to the control unit. The procedure of inspection inside the tank is tedious and would require several days to complete. Therefore it is logical to start trouble shooting the electronic parts and other related areas outside the tank. The initial trouble shooting could not find any errors in the electronic parts and controller of the motor, thus inspection inside the tank could not be avoided. The details procedure is described in this paper. It was discovered that the top section coupling was misaligned due to slipped lock key. A small modification by mean of spot welding was made on the coupling to avoid potential slippage. The final stage of the correction action was to carry out voltage conditioning up to maximum energy of 3.15 MeV, followed by beam conditioning at prescribed levels. The experience attained through this event had boosted the confidence of all the technical personnel. It was an indirect training to strengthen the operation and maintenance capability of the group. The EPS3000 was back in operation after 4 days of downtime. (Author)

[en] Full-text: This paper was designed to look at the effects of gum irradiation on color change and container structure on several types of packaging containers such as petri dishes, glass bottles, paperboard boxes and plastic bags. The dosage applied to the packing container is 3, 10, 25, 50, 300, 500 kGy. Dose selection is made based on the frequency of dose requested by Sinagama customers. Changes in the color and structure of the container to the packaging container were visually performed 1 hour, 1 day to 1 month after irradiation. Visualization is a simple data collection for MINTec-Synagama user reference purposes. (author)

[en] Product dose mapping is the determination of the best product loading configuration which will be used during routine sterilization. In product dose mapping, dosimeters are placed throughout products at strategic locations to determine the zones of minimum and maximum dose. On previous Sinagama's product dose mapping method, a total of 240 unit's ceric-cerous dosimeter been used for a tote. Based on the data obtained from Irradiator Dose Mapping Report in 2004 and data from recent studies, the number of dosimeter to be used in product dose mapping can be reduced to 28 units without sacrificing precision and accuracy of the dose mapping results. This also led changes of the placing dosimeter method from Plane system to Coordinate system. Reduction of 88 % on dosimeters usage will directly reduce the cost of expenses on dosimeter, time and labor. (author)
