LINGKUNGAN FISIK DAN KUALITAS RUANG LUAR PADA PERUMAHAN PADAT DI PERKOTAAN (Studi Kasus: Kampung Kelurahan Petamburan dan Tambora Jakarta)
Full text linkThe high activity in the physical development of urban areas with a high impact of different types of pollutants in the environment of the city, including in the air. This phenomenon in turn lead to a decrease in air quality, health and environmental impact on the level of air in urban areas. This study will look at how the physical environment affects the quality of the air. Characteristics of the physical environment is reflected by the density, height and distance between buildings. The condition of the value of the air quality in an area affected by the micro climatic conditions such as temperature, humidity and wind speed. Air quality values are formed from the elements of primary air pollutant gas emissions of motor vehicles (CO). Descriptive research methods. which is based on field studies and literature and also a case study, as this study intensively describe the current state of the Kampung Petamburan and Tambora. Data collection technic is to take secondary data and survey measurements It can be said that the characteristics of the physical environment influenced by micro climate. Air quality is also affected by the primary air pollutants. Results of the discussion visible moisture factor has a significant role to control air quality.

A Review on Thermal Comfort Through Physiological and Psychological Phenomena on the use of Outdoor Space in Urban Areas
No full textOutdoor space is important in a city because it accommodates pedestrian traffics, and other activities, which significantly contributes to urban livability and vitality. This is a comprehensive discussion on the review of literature relating to thermal comfort of the physiological and psychological phenomena of the outdoor space user in the urban areas. Many studies assess thermal comfort which are merely measured the physiological approach that represents a physiological thermoregulation mechanism when the human body responds to climatic conditions and various environmental factors include air temperature, humidity, wind speed, and solar radiation. The importance of psychological aspects of an individual in considering the external environment needs to be observed as well. Contradiction between psychological behaviors and physiological thermal can be correlated within the theory of environmental behavioral learning.. The process of social learning, such as observation and education, is reflected in the psychological perception (fear of heat and sun exposure) and behavioral adjustment (using umbrella or seeking shade). Therefore, psychological phenomenon and unique behaviors cannot be directly explained by physiological mechanism of thermoregulation. Various models on how to assess thermal comfort will be discussed in a general framework, in order to develop an accurate model. The model can be used as a criterion in determining functional, healthy, and comfortable design of outdoor
Outdoor thermal comfort and behaviour in urban area
Full text linkOutdoor comfort is important due to the public spaces functions. Open spaces provide thermal comfort and a pleasant experience to improve the city life quality effectively. The influence of thermal comfort in outdoor activities is a complex problem. This paper presents a literature review and discussion of aspects of physical, psychology, and social behaviour toward outdoor thermal comfort. The valuation is determined not only by the “physical state” but also by the “state of mind”. The assessment is static and objective (i.e., physical and physiological characteristics) that it should be measured. Furthermore, an effective model to provide the knowledge of climatic conditions, as well as the dynamic and subjective aspects (i.e., psychological and social characteristics and behaviour), requires a comprehensive interview and observation. The model will be examined to describe the behaviour that is a reflection of perception and behaviour toward the environment. The adaptation process will constantly evolve so that it becomes a continuous cause between human behaviour and the spatial setting of the formation, which is eventually known as places and not just spaces. This evolutionary process is a civic art form
The Relationship Between Building Coverage Toward Both Thermal Comfort and Heat Island Intensity (A Case Study on High Density Housing at Kaliangke, Cengkareng, West-Jakarta)
No full textIn a very compact housing in Jakarta, the open space becomes very narrow. That physical environment prevents the air flow which is a predominant condition in hot humid climate. One way to solve the problems is by controlling the micro climate in the form of arranging the building and arranging vegetation. This case study on high density housing aimed at : (1) find ing out t he correlation between building density toward thermal comfort and heat island intensity. (2) gett ing the information about physical factor that contributes to the relationship. The data on thermal comfort and heat island intensity are gathered through direct measurements by using L utron scale on temperature, humidity, distance among the buildings and high building density . The data on building density are gathered through comparing the ratio between the open space and built space. The result o f this study shows that there is a strong correlation between building density and heat isl a nd intensity. However, high building density does not provide direct contribution to thermal comfort. Different building height affects thermal comfort in that area which confirms what Johansson,Erik; Emmanuel, Robinson (2006), argument on thermal comfort

Understanding Unplanned Settlement Structure As A Result Of Self-Organization In Jakarta
No full textCity design, as a continuous urban place transformation process, emphasizes the process rather than the product, therefore to understand the
physical characteristic of a settlement should be based on an understanding of its formation process. The aim of this study is to discover and understand
the features of those unplanned settlements, which have been created in an autonomous manner without any comprehensive planning. This study is
intended for understanding the complex settlemets structures as the result of self-organization mechanism. Through the mapping, organizing, and
structuring of the settlement structure elements, such as path system and land division system, using information extracted from maps, photographs and
field survey in Kelurahan Petamburan village, the study reveals that there is a strong relationship between the path system and land division system with
the hierarchy of socio-spatial units as the main determinant of unplanned settlement development. The pattern of the path network shows the importance
of the neighborhood unit as socio-spatial unit that driven the settlement evolution. The neighborhood unit represents a closed socio-spatial unit with
intact social and emotional relationships within its community, where effective self-organization mechanism takes place. Responding to the fact that there
is segregation in urban settlement structures, due to relationship between the path - land division systems and the hierarchy of socio-spatial units, one
approach to urban planning is reconfiguration or rescaling of the urban settlement and urban space hierarchy, as well as examining political roles and
socio-spatial implications of various stakeholders with different interests
Micro-Climate and the Use of Kampong-Kota Communal Space
No full textCommunal outdoor space functions as a social space, especially in dense urban housing, such as in a city. The microclimate represents local climatic conditions consisting of temperature, humidity, wind and solar radiation. Many previous studies have looked at the relationships and effects of microclimate that have an impact on the intensity and behavior of outdoor space use. Unfortunately, this research has never been carried out in a dense communal space such as a urban informal settlement. Because there are people who tolerate and end up enjoying feelings of warmth and heat, depending on expectations and thermal experiences in the past. The objective of this study was to assess how much the influence of microclimate elements on the space use is related to preferences on microclimate and spatial use activities. A case study was conducted in a communal space in the informal settlement of Petamburan, Jakarta. The Field Survey included a structured interview with standardized questionnaire and observation of activities in the communal space, along with daytime microclimate monitoring. Data analyzed with PLS (Partial Least Squares) program to obtain the first model showing the measurement model and the second model which was a structural model that shows the estimated power of the equation model among the measured latent/construct variables. The analysis showed that a person's behavior in the form of the arrival rate (frequency) in using their communal space cannot only be evaluated from the conditions of the microclimate in the form of wind but need to be seen first from their preferences (hot and humid) on the microclimate. These results will serve as guidelines for architects and urban designers in describing conditions and possible further developments to improve microclimate conditions based on the physical design of urban space

Analysis of Risk Factors of HPS in Goods and Services Procurement for Jakarta Property Projects: Mitigasi Risiko HPS Berbasis Digital pada Pengadaan Proyek Properti
No full textThe procurement of goods and services for property projects in Jakarta faces various challenges, primarily due to inaccuracies in the Self-Estimated Price (HPS), which lead to significant risks in cost, time, and quality. This study seeks to identify the dominant risk factors caused by HPS inaccuracies and propose effective strategies to mitigate their impact on property project procurement. The research uses the Analytical Hierarchy Process (AHP) method, with 54 respondents involved, to evaluate three key risk categories: cost, time, and quality, based on the effects of HPS inaccuracies. The study finds that these inaccuracies undermine budget efficiency, cause delays in procurement processes, and negatively impact the quality of goods or services received. Cost-related risks include document instability and unforeseen expenses, while time-related risks involve delays and frequent revisions of the HPS. Quality-related risks stem from the use of substandard materials and the failure to meet project specifications. To mitigate these risks, the study proposes updating the HPS with up-to-date market data, conducting regular price surveys, enhancing the skills of procurement teams, adopting digital technologies such as e-procurement systems, and improving supplier selection processes. These strategies aim to improve procurement efficiency, enhance project quality, and ensure cost-effectiveness, ultimately leading to better project outcomes.Pengadaan barang dan jasa untuk proyek properti di Jakarta menghadapi berbagai tantangan, terutama disebabkan oleh ketidakakuratan dalam Harga Perkiraan Sendiri (HPS), yang mengarah pada risiko signifikan terkait biaya, waktu, dan kualitas. Penelitian ini bertujuan untuk mengidentifikasi faktor risiko dominan yang disebabkan oleh ketidakakuratan HPS dan mengusulkan strategi mitigasi yang efektif untuk mengurangi dampaknya terhadap pengadaan proyek properti. Penelitian ini menggunakan metode Analytical Hierarchy Process (AHP), dengan melibatkan 54 responden, untuk mengevaluasi tiga kategori risiko utama: biaya, waktu, dan kualitas, berdasarkan dampak ketidakakuratan HPS. Hasil penelitian menunjukkan bahwa ketidakakuratan ini mengurangi efisiensi anggaran, menyebabkan keterlambatan dalam proses pengadaan, dan berdampak negatif pada kualitas barang atau jasa yang diterima. Risiko terkait biaya mencakup ketidakstabilan dokumen dan pengeluaran yang tidak terduga, sementara risiko terkait waktu melibatkan keterlambatan dan revisi HPS yang sering terjadi. Risiko terkait kualitas berasal dari penggunaan material substandar dan kegagalan dalam memenuhi spesifikasi proyek. Untuk mengatasi risiko ini, penelitian ini mengusulkan pembaruan HPS dengan data pasar terkini, melakukan survei harga secara rutin, meningkatkan keterampilan tim pengadaan, mengadopsi teknologi digital seperti sistem e-procurement, dan memperbaiki proses seleksi pemasok. Strategi-strategi ini bertujuan untuk meningkatkan efisiensi pengadaan, meningkatkan kualitas proyek, dan memastikan efektivitas biaya, yang pada akhirnya menghasilkan hasil proyek yang lebih baik
Prediction of natural ventilation performance through a comparative study of interior void and courtyard void designs in two-storey urban row houses
No full textNatural ventilation is an important passive design strategy for improving indoor environmental quality while reducing dependence on energy-intensive mechanical cooling systems. However, in dense urban contexts, two-story row houses often face airflow limitations due to compact layouts, narrow facades, and limited openings. This study aims to predict and compare the performance of two natural ventilation strategies, namely interior void and courtyard void. The research methodology uses three analytical approaches: Convex Space and Computational Fluid Dynamics (CFD) simulations to evaluate airflow circulation patterns, velocity distribution, and indoor temperature. The study was conducted on a two-story row house prototype at Summarecon Residence, Bekasi, with a floor plan area of 6 × 14 m (84 m2 per floor). The position and dimensions of the inlet and outlet were made the same in each scenario, while external parameters such as average wind speed and outside temperature in 2024 were used in the simulation. The results show that the courtyard void produces better ventilation performance with an average wind speed of 2.17 m/s and a temperature of 33 °C, compared to the interior void, which only reaches 1.17 m/s with a temperature of 33.43 °C. In addition, the area near the courtyard had a maximum wind speed of 6–7 m/s, while the interior void had 5-6 m/s. These findings provide evidence-based recommendations on the importance of integrating passive ventilation strategies in row house design
