Indonesia is a tropical country, which consists of dry and rainy seasons. Because Indonesia is an archipelago that lies across the Equator and has a hot-humid climate. To achieve thermal comfort, the scientific use of passive cooling design is needed. Passive cooling techniques, especially in buildings, aim to control air conditions and optimize the process of dissipating unwanted heat in order to maintain air temperature and humidity within the recommendation of thermal comfort. Currently, in South Jakarta, the construction of Tanjung Barat Station Flats is being carried out. Later in this building, especially the podium area on the 2nd floor, will not only be used by the flat occupants but also as a public facility for the community. However, with its zoning location, this building is expected to operate without the use of air conditioning. So, based on several types of passive cooling techniques, one way to achieve thermal comfort without the use of air conditioning is through the usage of natural ventilation. This is because natural ventilation is the most appropriate type of cooling for hot-humid climates. The purpose of this paper is to create a potential passive cooling technique of ventilation openings that can be used for the 2nd floor area of the Tanjung Barat Station Flats, and to analyze the potential of ventilation openings for the podium area on the 2nd floor while also calculating the cooling load. From the potential results of the analysis of passive cooling techniques in the Tanjung Barat Station Flats in the form of ventilation openings, it is hoped that it can be used in these and other buildings, to achieve thermal comfort without the use of air conditioning."

The increase in carbon emissions has prompted the Indonesian government to set a target of carbon neutrality by 2060 and implement policies promoting the use of electric vehicles to support the achievement of this target. Electric vehicles are equipped with electric motors that convert electrical energy into mechanical energy to propel the vehicle. During this energy conversion process, the motor experiences an increase in temperature due to various losses that cause the motor temperature rise. If the heat continues to increase and the motor temperature exceeds 60°C, it will reduce the performance or even lead to damage. Therefore, there is a need for a cooling system that can maintain the electric motor's temperature within its working range. This study aims to investigate and test the Rotating Heat Pipe (RHP) as a passive cooling system for electric motors. The objectives of this research are to develop measurement methods for RHP testing and evaluate the performance of the RHP. The study employs an RHP with installed thermocouples on its surface. Additionally, a slip ring is utilized to test its capability as a connector of the data acquisition module and the thermocouple sensor. The research confirms that the slip ring can be used to test the RHP due to its ability to measure temperature under rotating conditions. Furthermore, the use of RHP can reduces thermal resistance by 30-66% compared to stationary heat pipes."

"ABSTRACTPemanasan global merupakan isu lingkungan yang sudah cukup lama dibicarakan karena dampaknya yang berbahaya. Para arsitek perlu melakukan penanganan terhadap masalah ini, karena banyak emisi di atmosfer berasal dari bangunan. Hal tersebut mendorong para arsitek untuk merancang konsep bangunan berkelanjutan yang berfungsi untuk mengurangi emisi dengan meningkatkan efisiensi energinya. Seiring berjalannya waktu, bangunan berkelanjutan diterapkan di berbagai jenis bangunan hingga terlahir istilah bangunan pasif yang saat itu diterapkan pada rumah tinggal di Jerman yang menjadi tempat lahirnya konsep bangunan pasif. Bangunan pasif merupakan bangunan yang memanfaatkan keadaan iklim setempat sehingga penggunaan energinya efisien. Bangunan pasif tropis yang dibahas dalam penelitian ini merupakan bangunan pasif yang dimasukkan ke dalam konteks iklim tropis sehingga menciptakan bangunan yang dapat menyesuaikan dan memanfaatkan iklim tropis. Bangunan pasif tropis bisa diterapkan di berbagai jenis bangunan, termasuk sekolah. Pembangunan sekolah di Indonesia jarang sekali dipikirkan efisiensinya, sehingga sekolah dapat menjadi bangunan yang menghasilkan banyak emisi. Beberapa sekolah di Indonesia dirancang menyesuaikan prinsip bangunan pasif tropis, yaitu Sekolah Alfa Omega di Tangerang dan Sekolah Bogor Raya di Bogor. Walaupun kedua sekolah ini belum menjadi sekolah dengan prinsip bangunan pasif tropis yang sempurna, tapi Sekolah Alfa Omega sudah mendekati prinsip pasif tropis dibanding Sekolah Bogor Raya.

ABSTRACTGlobal warming is an issue which has discussed often for a long time because its impacts are dangerous. Architects have to handle it, because a lot of emissions in the atmosphere come from buildings. That case encourages architects to design sustainable building which purpose is to reduce emissions by increasing energy efficiency. As time goes by, sustainable building is applied in the various types of building until the term of passive building appeared which was being applied in the house in Germany which made passive building concept appear. Passive building is a building that take the advantages of local climate so the use of energy will be efficient. Tropical passive building that discussed in this thesis is a passive building that incorporated in the context of tropical climate so it becomes building that adapts and take advantages of tropical climate. Passive building can be applied in every type of buildings, including schools. School construction in Indonesia has rarely thought the efficiency, so the school can become a building that produces a lot of emissions. Few schools in Indonesia are designed almost approaching tropical passive building principles, these are Sekolah Alfa Omega in Tangerang and Sekolah Bogor Raya in Bogor. Even both of these schools are not the school that has the tropical passive building principle perfectly, though Sekeloah Alfa Omega is closer to the principles than Sekolah Bogor Raya."
