Published: July 2024

The government, non-government organizations and community leaders in some countries were challenged to design and implement policies, programs and systems that could help local communities to overcome various threats. Changes of situation in the community, such as relocation, was considered a threat. In Indonesia, especially DKI Jakarta, in order to implement the Urban Environment Management Program, the government relocated the community who occupied illegal land to simple rental flat (rusunawa). People who were impacted by this policy had to adjust themselves to the new environment to make living, and some other chose to stay in a modest flat. The concept of community resilience has been an interesting issue as it dealt with the ability of something, someone or even society in overcoming difficulties, to recover and return to normal conditions at the right time. This study was done to propose a conceptual framework for community resilience for the residents of modest rental flats and to determine a standard method to examine the community resilience among residents of modest rental flat who were impacted by the relocation policy. Literature review was done to obtain secondary data and relevant scientific literature. In addition, observations were done to several modest flat which were established prior to the relocation policy (Marunda, Rawa Bebek and Kapuk Muara Penjaringan). To measure the strength and direction of the independent variableâ€™s contribution to the dependent variable, Variance Based Structural Equation Modeling was administered using the Smart-PLS program. The proposed conceptual framework for community resilience among the residents of modest flat covered 8 (eight) aspects, namely: 1) economy; 2) social; 3) culture; 4) human resources; 5) ecology; 6) physical; 7) politics and government and 8) technology. Those aspects should be taken into consideration in order to increase the capacity of modest apartment to stay. For the government or policy makers and information planners, the proposed framework can be used as an input for policy making, determining the priority scale, fund allocation and the enhancement of the sustainable flat housing development programs.Â Â

WP-Rank: Rank Aggregation based Collaborative Filtering Method in Recommender System
Authors: Lestari Sri , Bharata Adji Teguh , Erna Permanasari Adhistya 
Published: July 2024

Collaborative filtering with a traditional rating-based approach uses interaction records between users and systems to measure similarity, prediction, and generate recommendations. However, traditional rating based cannot capture user preferences of different products. To overcome this issue, the ranking based approach, such as the Borda method has been used. The method takes advantage of rating data to determine the position of the product in the list of preferences as the basis for determining product points. However, the list of the preferences which is merely based on rating data, results in an insufficient accuracy of the recommendation. This paper, therefore, proposed a novel approach namely the WP-Rank aggregation method which maximizes the use of rating data to generate product weight. The experimental results show that the WP-Rank method was superior to the Borda method with NDCG average value difference of 0.0220. However, the WP-Rank method required longer running time with 0.0206 seconds lag from the Borda method.Â Â
