The Dock Construction Inter-island in Indonesia

Sea transportation is important to support economic wheels and equitable distribution in inter-island areas in Indonesia. Therefore, adequate transportation facilities and infrastructure need to be provided. With the availability of docks, transportation of goods, services or human transportation can be easier and more efficient. In addition, Indonesia's pulai coast has become a tourist attraction. The types of docks in Indonesia are adapted to the facilities and needs of berths and their functions for the island community. The pier construction is planned to use the method of analyzing the data according to the water, seismic data, wind data, the availability of local materials, size and layout planning and structural planning. The purpose of this study is to find out the general shape of the interisland pier structure in Indonesia and the factors that influence its planning. The method used in this study is a literature review on the interisland pier in Indonesia. The results of the literature review indicate that there are three forms of pier structure in Indonesia with the most form being the quay form which is dominated by the transportation functions of loading and unloading trade goods, and the form of jetty which is dominated by the human transportation function. The shape of the jetty is generally not only made from concrete foundations and deck plates but also uses local materials.

Investigation of Air Circulation for Indoor Air Quality of Middle-Class Apartment in Jakarta, Indonesia

The most significant energy used in middle-class apartments is the air circulation unit. The use of energy from the air circulation system is related to the comfort of the user in the housing unit, so it adjusts to the applicable standard. The objection of this study is to investigate the optimization of the air circulation system in middle-class apartments in an urban area. The method is a comparative study of the government standard. The stages of the research did site observation, take air quality measurement, and interview with the questionnaire. Indoor air quality data collected are temperature, relative humidity, CO, and CO2. The data measurement compared to SNI 03-6572-2001 on Procedures for Designing Air Conditioning and Ventilation Systems in Buildings, Indonesian National Standardization. The questionnaire was to find out the comfort of residents on indoor air quality (IAQ). This study reveals that almost all air quality aspects are consistent to standard, except the temperature. The results of this study that meet the criteria related to air circulation are air movement 40%, relative humidity 65.5%, air movement 40%, CO 78%, and CO2 95%. The result of the questionnaires states that 72.4% of residents feel comfortable with the air quality in the dwelling unit. The size of the room and the adequacy of ventilation in the place influences the value of the air circulation system besides air movement.
