<![CDATA[Landslides is the top rank disaster in the number of incidents in Batu City. Currently, the handling of landslides in Batu City still lack preparation in preparedness phase. In preparedness phase, as an early step before a landslide take place, need a systematic disaster management. The disaster management refers to the use of a framework as a guideline to understand disasters that will occur. Batu City have developed a framework as a guideline for landslide management, but the quality and maturity are questionable. Therefore, this study proposes an evaluation of conceptual framework for landslides natural disaster management. The specific objective is to know the quality of proposed framework, find the weakness and strength. Evaluation is held by using featured based analysis which using seven criteria i.e. background, goal, model, content, legitimation, implementation and contribution. The result shows that the framework  is feasible to use as a guideline to manage the landslide management in preparedness phase in Batu City.]]>

<![CDATA[Heterogeneity of protocol communications, data formats, data structure, and hardware specifications on the Internet of things can lead to an Interoperability problem. The solution provides middleware that capable to work in heterogeneity communications, data formats, etc. This paper proposed. A cloud-based middleware that provides a communication interface to receive data from sensor nodes based on Restful and CoAP. Received data then stored in heterogenous IoT data storage based on the NoSQL database. From experiment and testing, interoperability testing methodology was used. The result shows proposed middleware can receive data from both protocols. The received data could store based on structure data or unstructured data on IoT data storage.]]>

<![CDATA[Proportional tuition fees assessment is an optimization process to find a compromise point between student willingness to pay and institution income. Using a genetic algorithm to find optimal solutions requires effective chromosome representations, parameters, and operator genetic to obtain efficient search. This paper proposes a new chromosome representation and also finding efficient genetic parameters to solve the proportional tuition fees assessment problem. The results of applying the new chromosome representation are compared with another chromosome representation in the previous study. The evaluations show that the proposed chromosome representation obtains better results than the other in both execution time required and the quality of the solutions.]]>

<![CDATA[The e-commerce market becomes one of the markets with the most promising growth. A number of studies on e-commerce have been investigated, but only a little attention is paid to the factors that may create e-commerce customer loyalty, even though customer loyalty is one of the primary keys to improve the performance of e-commerce businesses. This research offers a conceptual model focused on purchases to investigate the factors that affect customer's loyalty and when it is formed. Specifically, this paper intends to examine the relationship between the e-commerce overall quality on the perceived usefulness, perceived value, satisfaction and trust. This paper also verifies the relationship between perceived usefulness, perceived value, satisfaction and trust in the e-loyalty. The method of online survey is used for the data collection. From 1457 of the distributed questionnaires, 960 were completed and returned, resulted 65.8 percent response rate. The data is then analyzed using the Structural Equation Modeling (SEM) method. The research findings contribute to filling the knowledge gap regarding the defining factors of customer loyalty which may help the e-commerce provider in developing e-loyalty to increase e-commerce profitability.]]>

<![CDATA[Paratransit (mikrolet) was very popular in Malang city. However, their popularity is reduced by the availability of wide variety of more modern and online public transportations. One of the obstacles commonly faced by passengers of mikrolet is the limited information about the routes taken by mikrolet. In this paper, we proposed a prototype of service that can generate trip planning by mikrolet. We use depth-first search (DFS) algorithm as the basis to build our solution because it is relatively simple to modify. The service for trip planning available through REST web service and utilize location-based service style. Based on functionality testing result, the proposed system successfully generate all trip plans as expected. From performance perspective, when the number of routes and plans increased, the overall system performance degrades, so in the future the proposed prototype and its algorithm may needs further optimization.]]>

<![CDATA[Language is a tool used for communication. Indonesia has a variety of languages, one of which is the Buginese language. As a language whose level of speakers exceeds five million, the popularity of this language begins to fade and is rarely used over the times. The Buginese language has its own letter called Lontara which consists of 23 letters. In addition to learning it difficult, educational media to learn this language, especially how to write letters is rarely developed. Learning this language is mandatory for formal school students ranging from elementary school to high school. However, a number of teachers noticed that Lontara writing lessons were very difficult for students to understand. Because of the difficulty level of writing, this research was conducted to answer and overcome these problems by developing an educational media called Lontara Augmented Reality. The research and development method (RnD) was utilized as the method in this study and it collaborates with ASSURE as the media development model. ASSURE model is used in the media design process. This media has an embedded learning model which called think-pair-share. The presence of this learninf model aims to enhance user skill in learning due to it provides learning with pair features. Educational media design has been validated by four media experts and four content materials validators. In the first iteration of validation, the average value of 3.90 was obtained with an average total score of 206.5 and a total percentage of around 78% (good category). After media being revised, an increase of 11% from the former iteration became 89% with 4.45 in average and total score of 235.75 (very good category). Furthermore, expert material content obtained an average value of 4.74 with a total average score of 99.5. with the percentage of the feasibility of the media reaching 95%. The percentage of usability testing results shows a great result with 96.91% in average and functionality tests around 100% which means that all of these functions this educational media application can work properly. in addition, performance testing and compatibility results show a normal activities. Memory and CPU usage are in normal conditions and not disturbing the applicaton performance. Lontara Augmented reality compatible in many android smartphones. Around 15 types of devices have been installed and it can run normally in these devices.]]>

<![CDATA[Citizen participation in collect and distribute information increase the role of the citizen involvement in local issues and increasing the benefits of society for the government and the environment. The contribution of citizens can be useful in helping to deal with environment problems and assist certain parties in meeting data needs, this is commonly referred to as citizen science. In its development, citizen science involvement in providing information began to involve social media as a platform for sharing information. In this study we try to explore citizen science of Indonesia, we conduct case study exploring how citizen in Indonesia used social media such as Twitter in response to one of the country’s worst disaster in 2018 namely Lombok Earthquake. By analyzing these user generate message we may know what the response of Indonesian citizen during event and understand more about citizen science in Indonesia through social media including its role and contribution. The information also may assist local communities in obtaining up-to-date information, providing assistance according to needs of the populace and use to manage and plan disaster relief both during and after the event.]]>
