In the digital and Internet era, companies are racing to profile their target users based on their online activities. One of the reliable sources is the news articles they read that can represent their interests. However, extracting latent information from the news articles is not an easy task for a human. In this paper, we introduced a practical model to automatically extract latent information from news articles with pre-determined topics. Our proposed model used unsupervised learning, thus alleviating the need for humans to label news items manually. Doc2vec was used to generate word vectors for each article. Afterward, a spectral clustering algorithm was applied to group the data based on the similarity. A supervised Long Short Term Memory (LSTM) model was built to compare the clustering performance. The best 1, best 3, and best 5 scores were used to evaluate our model. The result showed that our model could not outperformed LSTM model for the best 1 score. However, the best 5 score result indicated that our model was sufficiently robust to cluster the articles based on topic similarity. Additionally, the proposed unsupervised model was implemented in both an on-premise server, and a cloud server. Surprisingly, our proposed method could run faster in the cloud server despite its less number of CPU cores.

Many countries are still dependent on fossil fuels as their primary energy supply. However, there is a growing concern about the sustainability and the environmental issue of fossil fuels. Therefore, it is important to utilize renewable resources as the energy supply, such as solar energy. As a country with a tropical climate, Indonesia has a great potential to use solar energy, due to the abundance of sunlight exposure. The present study aims to analyze several meteorological parameters for the installation of photovoltaic (PV) technology in Jakarta, Indonesia. The meteorological data provided by the Ministry of Environment and Forestry, Indonesia from 2008-2021 were used at three different locations in Jakarta. Data visualizations were used to show the difference between each variable in different locations. In addition, the statistical difference between the variables in the three locations was also examined using the Mann-Whitney U test. The test shows that all parameters are evenly distributed in the three locations except for a moderate difference in air temperature in the two locations. Furthermore, the monthly analysis of the parameters also indicates that the dry season, especially from August to September, would be the optimal time to utilize PV technology. Hence, this study would be useful to give preliminary insight regarding a site-specified assessment of PV plants in Jakarta based on local meteorological data.

作者： Sutantio, Aditya Anwar, Nadjadji Wiguna, I Putu Artama Suryani, Erma Post Graduate Program Civil Engineering Department Institut Teknologi Sepuluh Nopember Jalan Raya ITS Surabaya 60111 Indonesia Civil Engineering Department Institut Teknologi Sepuluh Nopember Jalan Raya ITS Surabaya 60111 Indonesia Information System Department Institut Teknologi Sepuluh Nopember Jalan Raya ITS Surabaya 60111 Indonesia

Introduction: Despite its contribution to urban development, high rise residential projects also cause adverse impact on the living environment. To address the problem, a sustainable construction as a new paradigm has been introduced. Various papers have examined the importance of sustainable construction. However, most studies focused on social and environmental aspects and with few consideration on the economic objective of the business. This study aimed to fill the research gap by presenting a dynamic model to improve social, environmental and economic performance of sustainable construction for high rise residential projects in developing countries. Methods: This study started with a literature review as a basis for a qualitative survey conducted in thirty high rise residential projects in Indonesia, to identify the influencing factors and the interrelationships. To analysis the data, a system dynamics approach was utilized. Results: The simulations reveal that the current regulation and construction practices are insufficient to reduce environmental negative impacts. In order to formulate better policies, three scenarios comprised the implementation of building energy regulation, tax incentives policy, and a policy mix were employed. The results show that the scenarios could improve construction sustainability performance in some extends. Conclusion: The combination of building regulation and tax incentives policy is effective to achieve environmental and social as well as economic aspects of sustainable construction which is suitable for investors. Based on the results, it is concluded that the model can be used to formulate various policies in the future to enhance sustainable construction of high rise residential projects in developing countries. © 2022 Sutantio et al.
