Abstract

The hybrid concept that develops in urban community settlements in an unplaning manner has led to various forms of settlement patterns that are adapted to social, economic and environmental conditions. This hybridity condition is potential for more innovative settlement consolidation efforts. This research was conducted to examine the quality of the hybridity formed in urban village settlements in Sindulang Satu Village, Manado, and to find the consolidation principle of settlement patterns by developing hybridity values at the site location. The quality of the hybridity was examined based on the perspective of programming hybrid, operational hybrid and spatial hybrid. This study used a qualitative research method, with modeling and experimental simulation technique approach. The analysis of settlement space performance was done by statistical calculations and graphical analysis using space syntax method. The research data was obtained using questionnaire, interviews and observations methods of samples that met the criteria of purposive sampling. The results of this study showed the potential of the hybridity in site locations with good quality, so that it became a consideration in formulating the principle of settlement pattern consolidation to increase site hybridity.

Abstract

The regeneration of coastal cities is one of the key architectural, urban design and planning innovation with the of industrial decline, enhance livability and sustainability and transform the image of the Indonesian archipelagic and marine decline. Thus, the various design and planning model for waterfront regeneration could be able to develop and expand into mixed-use and hybrid function which invent new conjunction of public and private interest. In this emerging waterfront projects, inter-coastal cities competition turns the city into a product which is marketed and sold, focusing attention on the imagery which iconed the city and differentiates it from other coastal cities. Such images includes iconography of local waterfront and function is linked to the rise brand marketing in the archipelagic context.These planning activities show there have been a wide array of responses the opportunities and problems associated with spatial networks of coastal areas of metropolitan cities. They recognize a process starting with growing the nodes (coastal activities centers) and clustering some sub spatial networks through bridging them by water transportation systems. This process is shaped by creating multi-layered network of regional coastal cities into some clusters and corridors in the context of waterfront metropolitan regeneration in archipelagic country. There are three level of network in archipelagic spatial planning concepts that is cities network, regional network (intra-island and inter-island) and global network for fostering the ability of other regions to rival Jakarta city dominance in activities and drawing power. This is only when the regional coastal cities have acquired this power can there be a harmonization of centralized and decentralized planning policy.

Abstract

Jayapura City is situated in the eastern tip of Indonesia and borders the neighboring country Papua New Guinea (PNG).  Its geographical conditions are very diverse dominated by hills leading to the formation of separated urban areas. Currently, there are two major urban areas, Jayapura and Abepura. Historically, Jayapura and Abepura were two old towns established in the Dutch rule, namely Hollandia Haven and Hollandia Binnen. They are detached by Skyline hills that hinder their complete physical merger.  The presence of two separated urban areas in Jayapura City is also reinforced by the image perceived by the residents regarding with the powerful visual image of those cities. It however forms unique and distinctive properties in the spatial structure of Jayapura City. This study examines how the influence of geographical conditions on the spatial structre of Jayapura City. Data collection was done through direct observation and interviews with respondents of Jayapura and Abepura. Direct observation was conducted to obtain data on the use of land that form patterns in Jayapura City area. While collecting data through questionnaires conducted to determine the image of residents of Jayapura City on the spatial structure of the city. The results showed that the geographical conditions in Jayapura City affect the formation of two separate parts of the city.  The geographical condition is also an element forming a strong spatial structure as a characteristic reinforces the visual impression of the existence of two cities in a “single city”.

Abstract

The purpose of this study is to explore the transformation of city form and its structure in Solo which has developed from time to time. The method of this research was carried out by a-three-archive research strategy as follows: primary files; secondary files and physical files. The primary files referred to the old Javanese documentary (examples: parintah, undhang-undhang, pranatan, piyagem, kakancingan, serat, gugat, penget, babad). The secondary files referred to the document of local, national and international historians (examples: Ricklefs, Lombard, Vorstensteden, Muljana, Notosusanto, Kartodirdjo, Sajid) and Javanese architecture researchers (Ronald, Ikaputra, Adishakti). While the physical files referred to the field research that was conducted by interviews and collecting the artefacts. The main findings of study of morphology in the city of Solo were: the 'skeleton' element grew in three formations (central, cluster and organic); the 'meat' element grew in three formations also (horizontal, vertical, and interstitial); and the 'blood' element increased from the native people (Javanese, Madura, Banjar) to foreign people (Chinese, Arab, India, Dutch) and changed from agricultural to non-agricultural activities. The other findings were the city of Solo was constructed by a-three-concept of urban design as follows: the organic concept which was conducted by native people; the colony concept which was conducted by the Dutch; and the cosmology concept which was conducted by the Javanese Kingdom. In 1500s-1750s, initially the city of Solo was a settlement grew at the bank of Bengawan Solo. Afterwards, in 1750s-1850s it developed into a combined water- and land- based urban fabric Since 1850s, the city of Solo has left the river transportation and changed into the land transportation. Moreover, in 1900s the city of Solo built the new technology of transportation and urban utilities as follows: train, tram (streetcar), electricity and water city installations. In 2000s, the city of Solo acquired the city problems like the other cities in Indonesia. The city problems were divided into three aspects as follows: the built environment; the natural environment; and the social environment. The accumulation of those problems made the city grow in decline direction that needs to be fixed by a-sustainable-city design. Abstract in Bahasa Indonesia : Paper ini berusaha mengupas tentang perubahan struktur dan bentuk Kota Solo setelah mengalami perkembangan dari masa ke masa. Metode penelitian dilakukan dengan studi pendekatan kearsipan, baik arsip primer, arsip sekunder maupun arsip fisik. Untuk arsip primer bersumber pada naskah-naskah dokumenter Jawa, seperti parintah, undang-undang, pranatan, piyagem, kakancingan, serat, gugat, penget dan babad. Untuk arsip sekunder bersumber pada buku-buku dari para ahli sejarah (Ricklefs, Lombard, Vorstensteden, Muljana, Notosusanto, Kartodirdjo dll) dan hasil riset dari para ahli sejarah arsitektur Jawa (Ronald, Ikaputra, Adishakti dll). Untuk arsip fisik bersumber dari artefak, elemen alam dan tradisi masyarakat yang diperoleh dari survey lapangan. Temuan utama dari studi morfologi Kota Solo pada tahun 1500-2000 adalah, elemen 'tulang' telah tumbuh membentuk berbagai formasi, yaitu memusat, mengelompok dan organik. Elemen 'daging' telah tumbuh secara horisontal, vertikal dan interestisial. Sementara elemen 'darah' telah berkembang dari orang-orang pribumi (Jawa, Madura, Banjar) bertambah dengan orang-orang pendatang (Cina, Arab, India, Belanda), dengan mata pencaharian dari agricultural ke non-agricultural. Temuan penting lainnya adalah, Kota Solo tersusun oleh tiga konsep yang berlainan, yang saling tumpang tindih, yaitu konsep organik oleh masyarakat pribumi, konsep kolonial oleh masyarakat Belanda dan konsep kosmologi oleh masyarakat Keraton Jawa. Kota Solo pada tahun 1500-1750 masih berupa kota tepian sungai di Bengawan Solo, kemudian pada tahun 1750-1850 berkembang menjadi kota campuran antara kota perairan dan daratan. Sejak tahun 1850an, Kota Solo mulai meninggalkan lalu lintas sungai dan berganti ke lalu lintas daratan, sehingga menjadi kota daratan. Apalagi sejak tahun 1900an, setelah dibangun teknologi baru pada sarana transportasi dan utilitas kota, yaitu jalur rel kereta api, jalur trem, jaringan listrik dan jaringan air bersih, maka Kota Solo benar-benar telah berubah ke kota daratan, meninggalkan hiruk-pikuk kota tepian sungai yang pernah terjadi di Bengawan Solo. Pada tahun 2000an, Kota Solo mengalami permasalah kota yang umumnya juga terjadi di kota-kota besar di Indonesia, yaitu permasalahan pada lingkungan alaminya, lingkungan buatannya dan lingkungan humannya. Akumulasi permasalahan kota itu menjadikan Kota Solo pada masa-masa mendatang akan semakin memasuki masa ke arah decline, sehingga perlu dicarikan grand-design kota yang sustainable. Kata kunci: morfologi, irreversible, kota, bentuk, struktur.

Abstract

Permukiman tepian sungai di Banjarmasin secara alami merupakan permukiman berbasis pada alam dan budaya huni sungai, saat ini mengalami degradasi kualitas kehidupan dan alamnya. Hal ini diakibatkan oleh bencana kebakaran, banjir dan tinggi resiko terjadinya urban heat island. Secara konfigurasi keruangan tidak terjadi hubungan dan keterpaduan antara ruang arsitektur dan infrastruktur kawasan yang berbasis daratan dan perairan. Fenomena yang terjadi adalah kepadatan, hubungan kawasan darat dan sungai yang lemah serta degradasi kualitas lingkungan. Selain itu kenyamanan termal kawasan pun sangat rendah, yaitu: aliran angin yang tidak lancar, kelembaban cukup tinggi dan suhu yang tidak nyaman. Penelitian ini mencoba melakukan eksperimen melalui pendekatan simulasi permibilitas ruang dan kenyamanan termal dengan menggunakan metode analisis ruang dengan program Space Syntax dan metode analisis kenyamanan termal dengan program Envimet. Penelitian ini membandingkan kondisi eksisiting dan usulan model arsitektur permukiman kampung beringkat yang berbasis arsitektur permukiman vernakular tepi sungai Banjarmasin. Kesimpulan dari penelitian ini adalah melalui pendekatan permibilitas keruangan yang mensimbiosiskan konfigurasi antara ruang darat dan air serta arsitektur kawasan dapat ditingkatkan kinerja kejelasan keruangannya tetapi secara kenyamanan termal tidak menunjukkan peningkatan kinerja secara signifikan karena morfologi kawasan yang relatif datar dan dengan proporsi ketinggian rata-rata bangunan yang rendah sehingga tidak terbentuk jalur pergerakan angin sebagai sarana ventilasi dan kenyamanan termal kawasan.

Abstract

Jayapura city is the capital of Papua province, located at the eastern end of Indonesia and the borders with neighboring countries, Papua New Guinea. From the results of population census in 2010 the population of the Jayapura city is 256.705 inhabitants with a number of indigenous people as much as 89.773 people (34.97%) and as many as 166.932 nonPapua population (65.03%).  This figure shows that in Jayapura city, the number of migrants is much more than the indigenous people.  The term amber and komin then appears that refers to the indigenous people of Papua (komin) and immigrants nonPapua (amber).  The high migration flows in Jayapura resulting diversity in socio-cultural and economic structure of the population.  This impacted on the formation of the population settlement patterns.  This paper discusses the ethnic heterogeneity in Jayapura city community in shaping the urban spatial pattern.  From the discussion, it is known that the existing settlements in Jayapura city consists of settlements indigenous peoples, settlements inhabited by a mixed population of Papua and nonPapua population, settlements inhabited by ethnic Papuans from outside the city of Jayapura and settlements inhabited by ethnic immigrants certain nonPapua. Settlement indigenous peoples still survive as indigenous settlements that have a spiritual religious meaning that must be maintained and protected. While the settlement of migrants Papua and nonPapua formed by some preferences, namely the ties of kinship, proximity to sources of livelihood (workplace) and social status.Kota Jayapura merupakan ibukota Provinsi Papua yang terletak di ujung timur Indonesia dan berbatasan dengan negara tetangga, Papua Nugini. Dari hasil sensus penduduk tahun 2010 jumlah penduduk Kota Jayapura adalah 256.705 jiwa dengan jumlah penduduk asli Papua sebanyak 89.773 jiwa (34,97%) dan penduduk nonPapua sebanyak 166.932 (65,03%). Angka ini menunjukkan bahwa di Kota Jayapura, jumlah penduduk pendatang jauh lebih banyak daripada penduduk asli Papua. Istilah amber dan komin kemudian muncul yang menunjuk pada orang asli Papua (komin) dan kaum pendatang nonPapua (amber). Tingginya arus migrasi di Kota Jayapura mengakibatkan kemajemukan dalam struktur sosial budaya dan ekonomi penduduknya. Hal ini berdampak pula pada terbentuknya pola permukiman penduduk. Tulisan ini membahas mengenai heterogenitas etnis pada masyarakat Kota Jayapura dalam membentuk pola keruangan kota. Dari hasil pembahasan diketahui bahwa permukiman yang ada di Kota Jayapura terdiri dari permukiman penduduk asli setempat, permukiman campuran yang dihuni oleh penduduk Papua dan penduduk nonPapua, permukiman yang dihuni oleh etnis Papua dari luar Kota Jayapura dan permukiman yang dihuni oleh etnis pendatang nonPapua tertentu. Permukiman penduduk asli setempat masih tetap bertahan sebagai permukiman adat yang mempunyai makna religius spiritual yang harus dijaga dan dilindungi. Sedangkan permukiman penduduk pendatang Papua maupun nonPapua terbentuk berdasarkan beberapa preferensi, yaitu adanya ikatan kekerabatan, kedekatan dengan sumber mata pencaharian (tempat kerja) dan status sosial.
