Abstract

The cracker cutter has been developed for many years, but still expensive, less effective, and not suitable  for wheat cracker cutting. The purposes of this research is to design a tool for suitable cutting, cheap and non-electrical wheat crackers. The design apply using stainless wire and mechanism of the suppressor for cutting. To be able to engineer the tools, it is necessary to prepare materials such as iron elbow, stainless steel, iron plates, bolts, stainless wires, pipes polyvinyl chloride (pvc) and springs.  The results show that an average cutting time about 12 kg/hour. In economic calculation there is discrepancies capacity per month 2060 kg or IDR. 123,600,000. There is an increase in capacity of 1700%.

Abstract

Software defect prediction model is an important role in detecting the most vulnerable component error software. Some research have been worked to improve the accuracy of the prediction defects of the software in order to manage human, costs and time. But previous research used specific dataset for software defect prediction model. However, there is no a generic dataset handling for software defect prediction model yet. This research proposed improvements to the results of the software defect prediction on the merged dataset, which is called generic dataset, with a number of different features. In order to balance the number of features, each dataset should be filled with a missing value. To fill the missing values, Weighted k Nearest Neighbor (WkNN) method was used. Then, after missing values were filled, Naïve Bayes was used to classify the selected features. This research needed to obtain a set of features which was relevant, then performed a feature selection method. The results showed that by using seven NASA public MDP datasets, Naïve Bayes with Information Gain (IG) or Symmetric Uncertainty (SU) feature selection presented the best balance value.Software defect, NASA public MDP, weighted KNN,Naive Bayes

Abstract

existence of shrimp paste farmer is supported by activities of auction fish place one of which located Ciparage beach, Karawang – West Java. Perpetrators produced 2 products such as shrimp paste and mixed shrimp paste. Utilization of Rebon shrimp by totality does not need other additives because drying process brings out the color that had itself so final product becomes redness. Involvement of Petek fish almost partially could reduce the color quality so the society used Rhodamine-B dye. This is widely spreading in the area because this matter is distributed by seller directly – door to door and the price is affordable – cheaper. Novelty this research is application of tray dryer with operating temperature variables – 40, 50, 60oC for 7 hours and the presence of Angkak as natural the red pigment that it is safe for human health. The results showed that the optimum condition of drying mixed shrimp paste was achieved by temperature 40oC. This is not about how much and quickly the moisture that evaporating into the air. Paradigm to chemical composition – organoleptic and antioxidant activity – DPPH method also was be consideration for that matter. Physically, this dried product had normal smell, salty taste, brown color, soft texture, solid shape, and normal appearance.

Abstract

The previous study showed that asphalt concrete using filler geopolymer generate a higher value of stability. On the other hand, the value of flow and the porosity of the asphalt concrete were out of the specification range. This study examines the aggregate gradation analysis to improve the characteristics of mixed asphalt concrete geopolymer. The gradation of aggregate is variated into three following the available specification. The range of specification is then separated into three, those are aggregate gradation upper specifications, middle specification, and lower specification. Filler comes from geopolymer paste, composed of fly ash which is mixed with an activator. Activator is an 8 molar concentration of NaOH solution and Na₂SiO₃. The weight ratio of Na₂SiO₃ over the weight of NaOH solution was 1.5. Geopolymer paste waited until reached the age of 28 days, then pounded up to meet the requirement size of the sieve No. 200. The test of mixture characteristics was conducted to see the comparison of performance from different gradations. The test results showed that middle gradation generating characteristics of the mixture which is higher than upper gradation and lower gradation.

Abstract

Autonomous maintenance taught operator to keep devices, create cooperation each employer and did problem solving that occurring in machine. This research described assembling of autonomous maintenance on PT NIKF – minor stoppages trouble in sachet production line. Our team used the OEE method to know the latest line condition and variety losses that causing the performance were not optimal. After that, the next steps were using visual losses map and diagram Pareto to get the detail (component with many losses). By Go See Think Do, the researcher could find much maintenance that must be done in SIC line 1. Through the application, this effort could reduce the losses of minor stoppages - 79,52%.
