Abstract
Virtual labs or Virtual laboratories are instructional approaches to facilitate the learning on some specific scientific or experimental procedures. The objective is to understand some lecture materials, to teach critical thinking skills and to improve problem-solving skills. In this paper, we propose the use of serious adventure game framework on virtual labs. The framework is expected to help the developers to build a new virtual lab system. The framework defines how the identification of the learning content, building a game design, and implementation into a game in a virtual lab. The framework has demonstrated how to change the learning materials into game contents, so that the resulting content can adapt a conventional laboratory. Game design should provide the right target learning but still fun for the learners. In this research, to validate the framework, we build three games, one of which is built using the proposed framework. To see the usability of the framework, these games have been used to see the capabilities of the games in increasing the knowledge of players and determine the importance of a specific component in the game design is proposed. We have tested these games to 59 high school students and compared with 17 high school students who read.

Abstract
This paper proposes authorization scenarios for updating population data systems that involve public participation through several different telecommunications channels, called Multi-Channel and Public Participation (MPP)-Based Population Administration System. This paper reveals a number of important technical aspects that arise and must be considered in the authorization scenario. This paper also discusses broadly the authorization techniques that have been used separately in many previous cases. Conformity between important technical aspects and authentication methods that are commonly used in system implementations is the basis for supporting the implementation of authorization scenarios. The proposed authorization scenario is to utilize a combination of Claim-Based and Multi-Factor authentication techniques because it has a match between important aspects and technical authentication. The combination of authentication techniques in the authorization procedure is able to verify and validate and determine the role of those who wish to collaborate in the service process.

Abstract
Tacit knowledge has not been revealed in an explicit and structured form, the low motivation of people to seek new knowledge from tacit knowledge and explicit knowledge. It takes a place that can channel the hidden knowledge into new knowledge. The purpose of this paper is to find out the mapping of community learning in informal education to support learning communities. Some of the previous studies of Community Learning were able to create smart, skilled, independent and competitiveness communities with learning programs at formal education. The internet community and media make a distance not an obstacle for people who exchange ideas. The power of bonding makes people help each other like families who have the same responsibilities. Community-based learning becomes an alternative in the future, where conventional learning will gradually be abandoned. Learning Community in the context of informal education is an alternative for busy individuals and it is difficult to find time to share knowledge. The method used is by survey method by defining the scope in detail, and determining the research question; do a search that involves selecting literary sources based on keywords, and determine inclusion and exclusion criteria to sort the types of references for further exploration. Community-based learning has unique things related to the learning process that is not possessed by formal education, among others, the interaction between community members, collaboration in sharing knowledge, quick feedback in solving problems, and self-reflection that often expresses opinions. unthinkable, the creation of actualization, problem-solving and learning by doing as well as learning community learning can also be done with experience-based learning.

Abstract
This research purpose to classify data export products of Indonesia against South Korea. The clustering method used in this research is the K-Means method, in K-Means cluster has a good degree of accuracy. This research examines how the use of the K-means method in case studies export products Indonesia against South Korea. From the results of clustering using K-Means method based on the value of the USD and Kg, then the generated 3 (three) clusters with cluster values are high, medium and low. Based on those results suggest that K-Means method can be used for inventory control of product reference or as Indonesia Indonesia Trade Promotion Center (ITPC) in Busan to view any export products should be retained and what are the export products should be improved to be promoted in South Korea so as to increase the number of export products of Indonesia against South Korea.

Abstract
Consumers are very important assets for the company. This is the reason why companies must design and use strategies that are quite clear in treating consumers. With the large number of consumers owned by a company, the problem that must be faced is how to determine potential consumers. With clustering methods in data mining, companies can identify potential consumers by grouping consumers. The purpose of the consumer grouping process is to find out consumer behavior and apply the right marketing strategy so that it can bring benefits to the company. This study discusses how to process data mining from consumer data at TB 80, which is a company engaged in the field of matrial, selling material and aims to find potential consumers who are expected to make managerial decisions to increase revenue. The data mining process begins with the process of preprocessing data (selection, clending and transformation) then in the clustering stage using the K-Means algorithm by determining the number of clusters. The clustering results of algorithm K-Means are used to group consumers and form consumer classes based on Frequency and Monetary attributes.

Abstract
PT. Makassar BAN and Fertilizer Retailers have problems, namely problems in making monthly reports that are used as supplementary documents in ordering fertilizers both to distributors and to producers. This is because both (PT. BAN Makassar and Fertilizer Retailers) do not have applications that are used specifically to process their daily transaction data, which have been managed conventionally (not based on databases), so that all daily transactions must be typed in making monthly reports re-use the MS application (Excel). Distributed Database-based application is one method that can be used to overcome the problems mentioned above. This application will be used to store transactions separately both in Fertilizer Retailers and at PT. BAN Makassar which will then be used as material in the preparation of monthly reports flowing from Complete Fertilizer Retailers to PT. The Makassar BAN is then forwarded to the Manufacturer. The results of this study are the application of distributed database-based fertilizer buying and selling transactions that are used as fertilizer online stock reporting from retailers to distributors
