Housing development, as part of economic development, must be supported by energy availability in order to achieve sustainable growth. One of the approaches to supporting renewable energy promotion is to design and build energy efficient housing. However, the optimal design of such buildings faces two conflicting requirements, namely the consideration of cost effectiveness and minimum environmental impact. The high costs of energy efficient buildings, such as the near Zero Energy House (nZEH), are due to the high price of the materials and equipment used, such as photovoltaic (PV) panels, insulation and other supporting materials. Indonesia is situated on the equator and benefits from sunlight throughout the year. Nonetheless, this potential has not been fully realized, as the solar-generated energy technology for housing comes at a high price. Therefore, the objective of this study is to find the cost optimum combination of validated design variables for an nZEH which suit the tropical climate conditions of Indonesia. Experiments and a case study are employed in the study to validate the design variables for an optimum nZEH design, which include building orientation, PV panels, fenestration, and passive design. The study finds that the cost optimum nZEH design achieved 72 percent site-energy savings and 21 percent savings in the total Net Present Value (NPV) of life cycle costs, with insignificant incremental initial construction costs in enhancing the design.

WBS (Work Breakdown Structure) plays an important role in every construction project. WBS is a hierarchy of decreasing scope of work to become the smallest level called a work package, making it easier in the process of project management and control. The current problem is that many contractors in Indonesia, both large and small contractors, do not understand the importance of using WBS in a construction project. This causes project performance to be less than optimal, especially on cost and time performance. Currently, WBS standards have been developed for building projects. In this study will look at the cost and time performance of the project from the use of WBS standard building. The sample used in this study are projects that have applied the use of project standards. The projects include Building X, Lecture Building Y, and Sports Facility Building Z. The method used in this study is the EVM (Earn Value Method) approach, collecting data using questionnaires. The results showed that using the WBS standard had an effect on cost and time performance. Good cost and time performance is shown in the Building X and Lecture Y buildings. While the cost and time performance of the Z Sports Facility Building tends to be unstable. This is because the work items that exist in the WBS standard are not in accordance with the project conditions, so it is necessary to adjust work items.

Fakultas Teknik Universitas Pancasila merupakan salah satu fakultas yang tengah meningkatkan perwujudan Green Campus. Salah satu faktor dalam perwujudan Green Campus adalah pengelolaan limbah padat. Saat ini pengelolaan limbah padat di Fakultas Teknik Universitas Pancasila masih belum optimal dan ini dapat dilihat dari banyaknya sampah yang belum terpilah di sumbernya. Oleh karena itu, perlu dilaksanakan pelatihan pemilahan sampah sebagai upaya peningkatan dalam pengelolaan limbah padat. Kegiatan ini diharapkan dapat mengurangi laju timbulan sampah di wilayah Fakultas Teknik Universitas Pancasila dan dalam jangka panjang dapat menjadi contoh bagi fakultas lainnya dalam kaitannya pengelolaan limbah. Metode dalam kegiatan ini adalah penyuluhan dan praktik secara langsung. Penyortiran didasarkan pada jenis sampah. Hasil yang diperoleh dari kegiatan ini peserta dapat memilah sampah berdasarkan jenisnya dan 95,3% dari total jumlah peserta mengatakan akan mulai memilah sampah untuk mengurangi dampak terhadap lingkungan.

The concern for environmental impacts is environmental degradation. One of the environmental problems is solid waste which has the potential to cause dangerous risks. Therefore, this study will analyze the risk of solid waste management factors at the university using the Failure Mode Effect Analysis (FMEA) method. Some information about risk factors from the solid waste management process was collected using literature studies and Ishikawa diagrams. The number of experts or experts used in this study was 5 people. The expected results of this study will be able to show the value of the Risk Priority Number (RPN) of the factors that are the target of the study. Furthermore, from this value, the level of risk can be known from each factor. Thus, risk evaluation (priority risk to be controlled) in the solid waste management process is focused on the highest risk category. The results of this study can be a guideline for evaluating solid waste management in universities in Indonesia and other developing countries. Various developments to improve the results of this study need to be carried out that will be useful for future actions.
