Authors: Enlina Auliasa , Sembiring Jaka 
Published: May 2020

Abstract
Increasing product variety raise the needs for analytical model to determine an efficient and optimal assortment based on consumer preference considerations. However, most of retailers have not considered the private label factor that can generate profit differentiation while building store loyalty. Apriori algorithm, which is often used to find consumer shopping habit patterns in retail, still has many drawbacks that can increase the burden of input, output, and processing time. Thus, this study proposes a specific procedure to establishing basic product based on private label, improving association rules by reducing transaction through Size of Transaction (SoT) attribute, and adopting maximum weighted value concept in apriori algorithm, therefore the result of association rules will be reflecting user considerations. This research produces a model to recommend assortment by considering private label and user reference, and building a system to integrate the whole process. Based on evaluation result, this study was able to reduce number of scanning databases, number of candidate and frequent itemsets generated, as well as strengthen the store image (qualitative) and increase company profit (quantitative).

On the Periodic Solution of an Oscillator Single Degree of Freedom with a Damping Coefficient that Changes Periodically
Authors: Waluya S. B. 
Published: May 2020

Abstract
In this paper will be studied a simple one degree of freedom system related to the dynamics of cable-stayed bridges. As a result of wind and rain that hits the bridge cable, it will cause vibrations from the cable to become unstable conditions. The presence of water flowing in the cable changes the cable cross-section as experienced by the wind plane. So, this is what causes the instability of cable vibrations. The idea to model this problem is to consider a horizontal cylinder supported by springs in such a way that only one degree of freedom, i.e. vertical vibration is possible. It will be studied a ridge on the surface of the cylinder parallel to the axis of the cylinder. Additionally, let the cylinder with ridge be able to oscillate, with small amplitude, around the axis such that the oscillations are excited by an external force. In this paper it will be studied the possibilities of the damping of the oscillator that changes periodically by using a perturbation method.
Liquefaction Resistance of Sand Mixed with Fines-Grained for Reclaimed Land
Authors: Yelvi  , Sudardja Handi , Elizabeth Shany 
Published: May 2020

Abstract
Liquefaction due to earthquakes can cause collapse, subsidences, landslides, lateral spreading, and sand boiling. The damage is commonly occurred at layer of water-saturayed granular sedimen with low relative density. Reclamation areas formed by loose sand are areas with high risk to liquefaction, such as damages occured in the reclamation area of Tokyo Bay Area (Fukushima Earthquake, 2011) and Wellington Port (New Zealand Earthquake, 2016). Some researches have stated that the gradation of soil grains, relative density and maximum acceleration of an earthquake affected the soil’s resistance to liquefaction. This paper presents the results of the experimental studies about the influence of fines-grained in the sand that has liquefaction potential which is used as a reclamation material to review its resistance to liquefaction. The experimental studies were carried out by adding fines-grained. A mixture of sand with fines-grains was made at a relative density of 25%, 50% and 75% under earthquake load with a maximum acceleration of 0.3g. Experimental results show that the increase in the fines content up to 30% and the relative density up to 75% reduces the resistance to liquefaction of the sand–fines mixture. The liquefaction resistance increases well as the increase of fines-grained and relative density.
