One of the companies in production and marketing of dodol in Singaraja area is UD. Dodol Made Merta. This company produces four variants of dodol namely dodol merah, dodol kayu sugih, dodol ketan hitam, and dodol kacang. All the four dodol variants have a different demand levels.This aim of this research is to determine the optimal prediction of the amount of production that must be produced every month so that profit can be maximized by minimizing the cost of production. This research was done using two methods ARIMA. The best model for dodol merah is ARIMA (1,0,1), dodol kayu sugihis ARIMA(1,0,0), dodol ketan hitam is ARIMA (1,0,0) and dodol kacang is ARIMA(0.01).

The present paper discussed a simple but specific case of scheduling tollbooth collectors in a toll section part of Jakarta toll road network. A number of requirements asked by toll road management were considered alongside with goal preferences in order to provide an efficient timetable for tollbooth collectors. A non-preemptive goal programming approach were employed to simultaneously minimized the shortage of workdays from its ideal level and the number of off-on-off scheduling patterns.

One of the home industry in Bali that produces beauty products is UD Citra Ayu Bali. This company has five types of body scrub scent, where the five types of body scrub has a different number of requests. UD Citra Ayu Bali has been doing production activities only when there is demand, so the production process is still less than optimal because it is still done randomly or unplanned. Therefore, this research is done to make production planning body scrub UD Citra Ayu Bali by determining the prediction of the number of products that must be produced every week so that the production process becomes optimal. By using the integer preemptive goal programming method, the optimal production number of the five types scrubs for 12 consecutive weeks is 212 pieces, 548 pieces, 328 pieces, 474 pieces, 506 pieces, 455 pieces, 103 pieces, 381 pieces, 63 pieces, 547 pieces, 59 pieces, and 454 pieces.
