Park and ride city terminal, Antapani Bandung

Bandung as a growing city has transportation problem as other big cities have in Indonesia. About 3.55 million person/day (7.2% move in the morning peak hour) is moved within the city to make more crowded. Thus, a good urban planning is necessary.  An urban planning cannot be separated from mass transportation system. City terminal is one of transportation infrastructures that serves mass transport on a local/city scale. City terminal is built by nodes of people activities such as schools, markets, residential areas, offices, etc. The principle of planning on land transport network system is to connect the system of city activities optimally according to the Masterplan of Transportation network. The purpose of this paper is to design a city terminal that can accommodate people movements and activities as well as can decrease the rate of personal vehicles uses by persuading people to use public transportation. City Terminal which was developed in the first nodes of people movements aims to break and cope up the density with functional approaches such as park and ride system. This paper explains how a city terminal could decrease a number of vehicle’s density by using park and ride concept in a residential area where is a start and end point of the system transport network. Park & ride is the type of terminal where the passengers’ personal vehicles can park and continue their journey by using public transportation instead. The paper ends by designing a park and ride city terminal located in Antapani, Bandung

Survey on household energy consumption of public apartments in Bandung City, Indonesia

Indonesia has been experiencing population and high economic growth in line with rapid urbanization. As a consequence, the needs for living areas increased faster and enormous number of residential buildings, especially apartments, have been developed in major cities, such as Bandung, resulting in further growth of energy consumption.Thus, it is necessary to develop energy-saving sustainable apartments in Indonesia in order to cope with escalating energy issues.  This paper reveals the detailed profiles of household energy consumption of apartments in Bandung City, Indonesia. A survey within the city was conducted (n=100) in 2016 to obtain household energy consumption data of public apartments. The detailed information about household appliances and domestic energy consumption profile among households were investigated through the face-to-face interviews and the measurement of appliances’ capacities by using the watt checker. The annual average energy consumption including electricity and gas was calculated. The results show that the annual average operational energy for public apartments are 9.8 GJ/year. The annual average energy for cooking accounts for the largest percentage (48%) of operational energy followed by refrigerator (27%), lighting (10%), entertainment (9%), cooling (3%), etc. The profiles of CO2 emissions are similar with those of energy and the potential energy-saving strategies for apartments in Indonesia were proposed

A Japan compact bus terminal; Review on Hakata bus terminal, Fukuoka

A mass transportation system has a main role in every development process of countries in the modern world. In Japan, transportation infrastructure such as train stations or bus terminals plays as an important node that determines the development of functions and other community activities in the surrounding area. Based on the compact city development concept, various types of transport infrastructure were constructed in the integrated area of city nodes and mixed with a various public and commercial functions and supported with a well-structured management of transportation systems. With the condition of limited land in the city nodes, transport infrastructure has to be built as a compact building. This paper reviews design and system of Bus Terminal in Japan from the architectural perspective with the issue of a compact building. As a study case, Hakata Bus terminal is one of Japanese bus terminal built with a slim building and vertically extended level without bus parking area. The platform was divided into three different floor levels with total ten building stories filled by various public and commercial functions. Time schedule, information system, people and vehicle circulation, and the other aspect become the main support to create a compact bus terminal. However, the commercial function is more prominent than the overall function of the building, thus making Hakata bus terminal does not show the typology terminal design in general. Overall, the terminal provides community services without ignoring the main function as a mass transportation system in a compact bus terminal

INDOOR AIR QUALITY AND HEALTH IN NEWLY CONSTRUCTED APARTMENTS OF INDONESIA: CASE STUDY ON THE EFFECT OF MODIFICATION

In Indonesia, sick building syndrome (SBS) and related health problems are suspected among the residents in emerging new urban houses constructed of modern building materials without sufficient material standards or minimum ventilation rates. First, this study investigates the current conditions of indoor air quality (IAQ) and health in newly constructed high-rise apartments in major cities of Indonesia, in contrast with traditional landed houses, the so-called Kampongs. Concentrations of formaldehyde and TVOC were measured, whereas a face-to-face interview was conducted. A total of 896 respondents were interviewed, and 207 rooms were measured during 2017-2019. The results showed that overall, the newly constructed apartments recorded higher formaldehyde levels compared to Kampongs. The status of the self-reported multiple chemical sensitivity (MCS) among occupants was significantly different between the two building types. Furthermore, the occupants with higher levels of TVOC, in particular, were associated with the higher MCS risks, especially in the apartments. Second, we conducted a modification project in several apartment units of Surabaya to examine the effects of exhaust fans on IAQ. In most units, the concentrations of both formaldehyde and TVOC were reduced after the modification. Further, a follow-up measurement was conducted in the same units for about a month.

THE ANALYSIS OF HOUSEHOLD ENERGY CONSUMPTION OF PUBLIC APARTMENTS IN INDONESIA: A CASE STUDY OF RUSUNAWA BUILDINGS IN BANDUNG CITY

This paper discussed what profiles of household energy consumption in the public apartments (namely Rusunawa) in Bandung, Indonesia. Data of household energy consumption were obtained through a survey conducted within the city in 2016. The energy consumption profiles of households and the household appliances were obtained through face-to-face interviews and measurements of appliances’ capacity using watt checker. Then, a calculation of the annual energy consumption, including gas and electricity, was conducted. The experimental results replied that the annual average operational energy for public apartments is 9.80 GJ/year, and the largest energy for the annual average energy is found for cooking (4.70 GJ/year) of operational energy followed by refrigerator (2.6 GJ/year), lighting (1.0 GJ/year), entertainment (0.9 GJ/year), cooling (0.3 GJ/year), power (0.2 GJ/year) and hot water (0.1 GJ/year). Most of the energy source of cooking came from LPG. Further, the operational energy usage patterns varied among households. The factor significantly contributing to the increase of the Rusunawa operational energy is the energy consumption for cooking and fridge. The profiles of CO2 emissions are identical to those of energy. Then, the potential energy-saving strategies for public apartments in Indonesia are proposed. The results of this analysis would be useful for further insights for policy making in Indonesia, specifically for the energy policy for achieving lowenergy as well as low-carbon societies
