A Case Study of a 15-Minute City Concept in Singapore’s 2040 Land Transport Master Plan: 20-Minute Towns and a 45-Minute City

The 15-Minute city concept emerged as a response to the hyper-motorized city. First popularized by the Mayor of Paris in 2020, 15-Minute City is an evolving concept that derived from its predecessors such as neighborhood-unit planning and walkable city. This paper explores the implementation of the 15-Minute City concept in city planning by using Singapore as the case study. In 2018, Singapore released its Land Transport Master Plan 2040 and which includes an ambitious concept of 20-Minute Towns and a 45-Minute City (2MT45MC) and has similar ideas to the 15-Minute City concept. Through various journal articles and media coverage, Singapore’s policy and regulation regarding its transport planning were thoroughly reviewed to find Singapore’s strategy and challenges in realizing the objective of its 2MT45MC concept. Normalizing active mobility and enhancing connectivity nationwide are the main strategies to overcome the biggest challenges faced: lack of legal backing in personal mobility devices and the country’s rigid zoning. Even though it is too early to say whether 2MT45MC is achievable or not, projects such as the North-South Corridor show that for a long-term plan, it seems feasible.

Memahami Perjalanan "Kampung Cyber" Melalui Lensa Actor Network Theory

<p class="Abstrak">Penelitian terdahulu menunjukkan tingginya risiko kegagalan dari proyek-proyek penerapan teknologi informasi dan komunikasi (TIK) untuk pembangunan. Salah satu tantangan utamanya adalah mendapatkan kepercayaan dari masyarakat dan memastikan bahwa program-program itu lestari. Penelitian ini akan membahas detail proses implementasi TIK untuk pembangunan menggunakan lensa Actor Network Theory. Detail proses implementasi TIK nantinya akan dianalisis berdasarkan fase-fase pada Actor Network Theory. Studi kasus penelitian ini adalah sebuah desa bernama “Kampung Cyber” di Yogyakarta yang sudah menerapkan TIK sejak tahun 2008. Penelitian ini merupakan hasil dari studi kualitatif berdasarkan wawancara dan observasi dari masyarakat Kampung Cyber beserta dengan tokoh-tokoh utama dalam implementasi TIK. Detail temuan penelitian ini dapat dijadikan referensi dalam implementasinya di daerah lain. Hasil penelitian menunjukkan Actor Network Theory mampu memetakan bagaimana proses implementasi TIK di Kampung Cyber. Hasil analisis juga menunjukkan perubahan peran Ketua RT yang di masa awal menjadi sangat dominan, yang akhirnya digantikan oleh masyarakat. </p><p class="Abstrak"> </p><p class="Abstrak"><em><strong>Abstract</strong></em></p><p class="Abstract"><em>Previous studies have documented failures in various information and communication technology for development (ICT4D) projects. One of the main challenges in ICT4D project is gaining the trust of the community and ensuring its sustainability. This paper presents stories from ICT4D project implementation through the lens of Actor Network Theory (ANT). The case is a village called "Kampung Cyber" in Yogyakarta. This study employs a qualitative approach using data gathered from interviews with the main actors and observations in Kampung Cyber. Details from the findings may be adapted as a reference to ICT4D project implementation in similar context. The finding unveil that the theory is very useful to explain the implementation process along with involved actors. The study also finds that the role of the leading actor (i.e. the head of neighborhood unit)) diminishes over time and the dominant role is taken over by the community. </em></p><p class="Abstrak"><em><strong><br /></strong></em></p>

PROSES GUBAH MASSA DAN SISTEM BANGUNAN PADA FLOATING HAVEN

Sinking Jakarta caused by land subsidence and rising seawater level become an international concern that was discussed for the last few years. It happens because of climate change that causes north pole ice melts and groundwater extraction. If we take a look whole of Jakarta, North Jakarta is the worst part affected by this issue. It happens because there is a 25cm land subsidence per year in North Jakarta. Within 50 years ahead, Jakarta will be an ocean, water will fill the entire dryland becoming wetland as predicted by research from the ITB geodesy expert team. This phenomenon becomes a huge problem as we know that Jakarta is the center of Indonesia's economy and will be the 4th biggest mega-city by 2030. Floating Haven presents as a proposed solution for Jakarta society's future dwelling. All of the design methods and strategies considering that this project will be located in the middle of the sea. LIVING, PRODUCING, and SUSTAIN, is an important key to this architectural project. This architectural project will be served for the smallest neighborhood unit that consists of 50 families or 250 peoples. Each point is planned to be modular, connected, and can adapt to a specific different function. Because of its modularity, this architecture can be duplicate gradually until it serves all of the sinking parts of Jakarta. Keywords: dwelling; floating; living; producing; sustainAbstrakPenurunan muka tanah dan kenaikan muka air laut akan mengakibatkan Jakarta terendam di masa yang akan datang. Hal ini menjadi isu yang dibahas dan menarik perhatian internasional beberapa tahun belakangan ini. Fenomena ini diakibatkan karena adanya perubahan iklim yang mengakibatkan es di kutub mencair dan ekstraksi air tanah secara berlebih. Jakarta terutama bagian utara menjadi kasus studi yang memerlukan perhatian khusus lebih dini. Hal ini dikarenakan adanya penurunan permukaan tanah Jakarta Utara 20-25cm / tahun (2050, 95% Jakarta Utara berada di bawah permukaan air laut) berdasarkan data Riset Tim Ahli Geodesi ITB, Heri Andreas. Melihat isu ini akan berpengaruh terhadap eksistensi Jakarta dan penduduknya, maka proyek ini akan menjadi usulan cara baru agar masyarakat dapat berhuni di atas air di masa depan. Di samping itu, hal ini tentu menjadi suatu permasalahan tersendiri dimana Jakarta merupakan kota padat penduduk dan sebagai pusat perekonomian di Indonesia ini. Floating Haven menjadi solusi bagi masyarakat Jakarta di masa depan untuk ber-dwelling. Berbagai perencanaan dan pertimbangan akan ‘sustainability’ di tengah ‘air’ memegang peran penting dalam proyek ini. Maka dari itu; hidup, produktif, berkelanjutan, menjadi kata kunci penting dalam perancangan proyek ini. Proyek ini nantinya pun akan melayani satuan unit lingkungan terkecil dari sebuah kota, yaitu RT / Rukun Tetangga yang terdiri dari 50KK / 250 jiwa. Setiap titik nantinya akan dirancang secara modular dan saling terkoneksi sambil menyesuaikan dengan kebutuhan akan fungsi yang ada. Modular ditujukan agar nantinya arsitektur ini dapat diduplikasi secara bertahap sampai pada akhirnya dapat melayani seluruh wilayah yang menjadi ‘lautan’ di Jakarta.

Analisis Potensi Genangan Tsunami dan Penentuan Jalur Evakuasi Berbasis Sistem Informasi Geografis di Desa Daruba Pantai – Kabupaten Pulau Morotai

Tsunami is one of the catastrophic events that threatened coastal areas in Morotai Island Regency. This is partly because the location of the regency is among several active faults. Therefore, the study aims to analyze the tsunami inundation area and determine a tsunami evacuation route in Daruba Pantai Village, South Morotai District. This study begins with the preparation of a digital elevation model and is compiled with other related maps to produce the tsunami inundation area at the study site. The study results show that a tsunami can hit 176.65 ha, with the disastrous and dangerous category being 5.02% and 0.66%. Meanwhile, specifically for the Daruba Pantai Village area with an area of 60.59 ha, the disastrous and dangerous categories are 10.72% and 1.30%, and the safe category is 36.61% and secure 23.07%. Furthermore, the preparation of the evacuation route is based on the scenario that residents from each zone of both the Neighborhood Unit (RT) and Community Unit (RW) are directed to follow the evacuation path to move towards the temporary shelter point and towards the safety zone.

Implementation of address recording management using the K-Means clustering classification algorithm in Kebayoran District, DKI Jakarta

The area is the center of problems in the administrative record management of Kebayoran District, because of its dense condition and it is difficult to determine land measurements due to the density of residential areas. The problem in Indonesia to this day is that the administrative boundaries of the kelurahan already exist, but the administrative boundaries for the Rukun Warga / Rukun Tetangga (RW / RT) do not yet exist. The local government of DKI already has a large scale map (1: 1,000) to map RW administrative boundaries. Large-scale mapping (Batas RW) is useful for accurate information on incidence of dengue fever or other diseases, thereby eliminating information bias due to the use of village boundary maps. Another benefit is the accuracy of address management for customers, for example PDAM customers, to facilitate verification of customer data with large-scale maps, especially those that only include RT / RW addresses, without mentioning street names and household numbers. The method used is data mining K-Means Clustering. By using this method, the data that has been obtained can be grouped into several clusters, where the application of the KMeans Clustering process uses Excel calculations. The processed data is divided into 3 clusters, namely: high cluster (C1), medium cluster (C2) and low cluster (C3). The iteration process of this research occurs 2 times so that an assessment is obtained in classifying the household / neighborhood unit based on the Kelurahan. The results obtained are that there is 1 neighborhood unit with the highest cluster (C1), there are 4 neighborhood units with 4 medium clusters (C2), and 5 neighborhood units with the lowest cluster (C3). This data can be input to the sub-district to disseminate information about dengue fever, health education, and for the accuracy of PDAM customer address management and others.

Morphological periodization of large-scale residential development in Krasnoyarsk

This article is dedicated to examination and testing of the modern methods of morphological analysis of the territories of large-scale residential development. The urban planning theory marks the emergence of works on the study of morphotypification of residential construction of different periods. A number of recent publications provide the analysis of the morphotypes of urban environment using GIS technologies to determine such parameters as the density of urban fabric, porosity and ratio of open and closed spaces, number of storeys in a building; nature of the relative positions of buildings in a residential group, neighborhood unit, etc. The author outlines the new vectors in studying construction patterns and evolution of topography of large-scale residential development plan. The goal of this research lies in determination of the morphological periods of large-scale residential development in Krasnoyarsk based on the analysis of topology, study of the structure of the plan based on geoinformation data analysis. The article aims to determine the construction periods of large-scale residential development through the use of mathematical analysis; analyze the topology of the plan of living quarters of various construction periods; establish the morphotypes of residential planning units that are characteristic to the periods of large-scale residential construction; substantiate the morphological periods of neighborhood units of large-scale residential development. The author describes the typical morphotopes of residential development of the city based on determination of the preferred geometry and number of storeys in a building: &ldquo;ribbon&rdquo;, &ldquo;dot&rdquo;, &ldquo;spline&rdquo;, &ldquo;L-shaped&rdquo;, &ldquo;U-shaped&rdquo;, &ldquo;circuit&rdquo;. The article conducts a comprehensive calculation of morphotopes based on the key indicators, and reveals the morphotypes characteristic to different periods of large-scale residential construction: 1st period (1960&ndash;1975) &ndash; &ldquo;ribbon development&rdquo;; 2nd period (1975&ndash;1990) &ndash; &ldquo;sporadic building&rdquo; due to varying geometry of the building plan; 3rd &nbsp;period (1990&ndash;2010) &ndash; &ldquo;mixed housing&rdquo; due to coexistence of different types of buildings; 4th period (2010&ndash;2020) &ndash; &ldquo;homogeneous development&rdquo; due to the presence of typical, recurring morphotope. Substantiation is given to morphological periods of residential construction.

The Chandigarh Sector

The neighborhood unit (Sector) in Chandigarh was conceived as a self-sufficient, repeated element to create the matrix of the city along with the hierarchical circulation system defined by the 7Vs to disburse traffic in an orderly manner. This arrangement was interfaced with a designed landscape at the behest of Le Corbusier and Dr. M. S. Randhawa whose passion for bio-aesthetics realized a city where landscape and built forms created a patina of the most charming capital of the modern world. Seven decades later, the city’s flowering landscape and modernist architecture continues to make it one of the best neighborhoods in which to reside
