DNS tunneling Detection Using Elasticsearch
Authors: Sani A F , Setiawan M A 
Published: January 2020

Abstract
Domain Name System (DNS) Protocol is a popular medium used by malware to perform ‘command and control’ in taking over victim’s computer, this technique called as DNS tunneling. Moreover, DNS tunneling can also be used to bypass captive portal hotspot in public places and worsen the network quality. However, in more dangerous stage, DNS tunneling can also be used to exfiltrate data from the victim’s computer. Instead of using DNS Protocol to translate domain name, the medium misused to bootleg the data. Those are the weaknesses which frequently used by the attacker to deceive network administrator. Our approach to this problem is analyzing the traffic using unique hostname as indicator of compromise and utilizing Elasticsearch tool to detect DNS tunneling. Elasticsearch will send an email to notify the administrator about DNS tunneling. The email contains information about domain suspected as perpetrator of DNS tunneling. The result from Elasticsearch can be used to add the domain blacklist, so the domain can no longer be used to perform DNS tunneling. Hopefully those combinations are able to support the network administrator to secure the network from DNS tunneling. Moreover, the result of network quality analysis shows that there is a rise in jitter value and packet lost when DNS tunneling happens.

Published: January 2020

Abstract
Marketing strategy is an important thing that must be developed by retail. A method that can be used to develop a marketing strategy based on customer buying pattern is Association Rule (AR). AR is the process of finding association relationships between products that occur in one transaction. The application of AR to analyze custumer buying patterns is referred to as Market Basket Analysis (MBA). Rule obtained from ARMBA is sometimes not enough to provide an analysis when the variability of costumer buying pattern is high. Overall Variability of Association Rule (OCVR) is an indicator that focuses on analyzing market basket which assumes high variability in custumer behavior in buying products. This study used custumer transaction data of a retail in Yogyakarta. The data consisted of 57784 transactions in a month involving 41248 items. This study produced rules for each period (weeks), then the rules were used for further analysis using OCVR. 59 rules produced on the 1st period, 48 rules on the 2nd period, 54 rules on the 3rd period, and 58 rule on the 4th period. From the rules obtained there were 17 rules have OCVR value smaller than 30%, thus these rules can be used to make marketing strategies. Product bundling and shelves product arrangement based on obtained rules were proposed as marketing strategies to promote product sales.

Published: January 2020

Abstract
Reactive dyes are a dye that can react with cellulose or protein, thus providing good colorfastness. Reactive dyes, besides being used to dyeing cellulose fibers, can also dye wool and silk fibers. One of the reactive dyes is remazol. Waterglass is a durable strong alkaline compound in the form of a thick colorless liquid. The use of waterglass in the textile industry itself varies greatly, including as a color reinforcement in the fixation process. Because of its essential function, the waterglass has become an urgent material for craftsmen, especially abstract batik craftsmen. Waterglass like it can’t be replaced, but it turns out there is a material that can be formulated to make artificial waterglass from salt, boarding, and water. For the media on dyeing, you can use a cotton cloth. Cotton cloth has strong properties (even when wet still absorbs), attracts body heat, wrinkles, shrinks, or shrinks (unless appropriately handled), is damaged by the sun, sweat and decay.

Abstract
The application of 5S can be used in assisting environmental management system standards. 5S (Seiri, Seiton, Seiso, Seiketsu, and Shitsuke) is a simple concept in managing workplaces for efficiency and waste reduction as well as optimizing quality and productivity through an organized environment. An environmental management system is part of a management system which used to manage environmental aspects, compliance obligations, and opportunity risks. ISO 14001: 2015 as an international standard of the environmental management system which refers to the PDCA (Plan-Do-Check-Action) cycle. The environmental management system at SMEs faces greater limitations compared to large companies. 5S can be used as a tool to improve environmental performances by reducing waste, pollution, and energy which will be easier to identify and control. In this study, it’s explained how the influence of 5S in fulfilling ISO 14001: 2015 standards in electrical Batik stove SME in which the application of 5S is not optimal and resulting in compliance with environmental management systems that less than the ISO 14001: 2015 standards. Factors affecting the application of both 5S and EMS are leadership and commitment, knowledge and training, communication, employee participation and motivation, and external factors such as law and regulation.

Influence of Transglutaminase Enzyme Incorporated into Protein based Edible Coating for Preservation of Spanish Mackerel Fish (Scomberomorus commersoni)
Authors: Karina S , Setiadi  
Published: January 2020

Abstract
Transglutaminases have been utilized in food technology to modify protein to improve rheological properties of food material or product. Edible coating is viscous solution that contains polymer structures, forming thin layer that covers surface of food material. Edible coating maintains quality of food product by becoming a barrier and protecting the surface from spoilage from internal and external causes. In this study, several concentration of transglutaminase enzymes were applied, acting as cross-linking agent into protein-based coating solution for coverage of Spanish mackerel fish meat. The fish meat samples were stored inside fridge with temperature of 10°C. Quality of fish meat was assessed each 5 days during 15 days of storage. The assessment of quality includes water content, pH and total volatile base of nitrogen (TVBN). Fourier Transform Infra-Red (FT-IR) was used to identify the activity of transglutaminase enzyme by the changes of detected functional group. Addition of transglutaminase has improved barrier properties of edible coating that maintained water content of fish meat better than control sample, but the by-product of enzymatic reaction has decreased quality of fish meat according to pH and TVBN results. FTIR spectroscopy showed changes in the secondary structure of protein (amide II).

Abstract
Gold mining Pipe with slurry was modified to observe its effect in pressure-discharge pipe. The fluid was transport using centrifugal pump, while the model simulated using solid work 2018 edition. Three models used in this case were: 28-inch pipe without reducer-pipe; 30-inch pipe without reducer pipe, and 28-inch pipe with reducer-pipe. Each model will produce the discharge pressure, slurry velocity, and the friction. The result shows that the 30-inch pipe without reducer will increase the pressure on the discharge pipe. However, the pressure is not as homogenous as 28 inch-pipe without reducers. 10 % of slurry produced less pressure because the friction occurred in the wall caused by the diameter difference. Meanwhile, the models in 28-inch pipe with reducer-pipe clearly show significant improvement of discharge-pipe pressure. However, the pressure is variety from the centre to the edge of the pipe, with the highest pressure located in the centre of pipe.

Abstract
Structure failure often occurs in the joint. This failure can adversely affect the comfort level of the structure. Knowing the behavior of interior beam-column joint structure resulting from the load is important, as it can help to predict the strength of the structure interior beam-column joint and comfort of the structure being worked on. One way to find out and predict the strength and comfort of the structure interior beam-column joint as a result of the load received is the experimental test and simulation. The simulation VecTor2 used to predict the shear force, crack, and displacement of the reinforced concrete column when applied the shear force. This simulation considered the effect of the bond stress-slip effect of behavior reinforced concrete. Bonds stress-slip gives a great influence on the strength and hysteretic response of the reinforced concrete beam-column joint. That is why this study considers the influence of the bond stress-slip on a reinforced concrete column. All the result of simulation VecTor2 using bond stress-slip effect would be compared with the result of the experimental test to see the behavior and accuracy of the simulation test.
