Abstract

Abstract Betawi is one of the indigenous cultures that inhabit the capital city of Jakarta. This culture was born from a fusion of several cultures that came to the Jakarta area. Betawi culture can be seen from the system of customs that are still preserved such as silat, traditional food, community life, and traditional buildings that are still preserved today. This research used a case study of the Betawi cultural area located in Setu Babakan, Srengseng Sawah, South Jakarta. Setu Babakan area is a stronghold of the Betawi cultural heritage site which is still preserved today. The research objectives of the Betawi architectural concept in the Setu Babakan area are as follows: to know the Betawi architectural Concept, to identify the Betawi architectural concept in the Setu Babakan area, and to find solutions related to the application of Betawi architecture concept in architecture buildings today. The research method used a descriptive method based on empirical facts. The data of this research consisted of primary and secondary data obtained from literature and existing field conditions. Betawi culture as the local culture of the capital city of Jakarta is increasingly marginalized, it is even not the majority in its own area. The results of observations on the site of 879 housing units were divided into original houses as much as 22.75% characterized the Betawi architecture and 77.25% did not characterize Betawi architecture. The application of Betawi Architectural Ornaments in the Setu Babakan area, especially seen in the following elements: pendopo or front porch of the house, langkan [Betawi balustrades], hanging lamps, doors, windows, blinds, roofs, and colors.

Abstract

The purpose of this research is to find out germinal of traditional Banjarese architecture in South Kalimantan. Using descriptive analysis method based on existing literature and the empirical evidence, hence it can be found germinal of  the traditional Banjarese architecture. Architecture that lifted as a comparison  is a traditional  architecture of Rumah Bubungan Tinggi (House of High Cam). Rumah Bubungan Tinggi is a traditional Banjarese architecture coming from  architecture of Malay that exists on coastal area. It has been formed far before the Banjarese formed itself. In its growth, the culture of  Dayak dan Java tribes and including Islam had also influenced. Physically, the environmental condition become primary factor of its physical form.Penelitian ini bertujuan untuk menemukenali asal mula arsitektur tradisional Masyarakat Banjar di Kalimantan Selatan. Dengan metode analisis deskriptif berdasar literatur yang ada dan bukti empiris, maka dapat ditemukankenali asal mula arsitektur Masyarakat Banjar. Arsitektur yang diangkat sebagai perbandingan adalah arsitektur tradisional Rumah Bubungan Tinggi. Rumah Bubungan Tinggi adalah arsitektur tradisional Masyarakat Banjar yang berasal dari arsitektur masyarakat Melayu yang ada di pesisir, yang telah terbentuk jauh sebelum terbentuknya Masyarakat Banjar. Dalam perkembangannya, kebudayaan Suku Dayak dan Jawa, serta ajaran Islam turut pula mempengaruhi. Secara fisik, kondisi lingkungan alam menjadi faktor utama bentuk/wujud fisik.

Abstract

Sleman district have many good lands for investment, cause price of land would be raised, so that people look for the area increasingly. Eventually affect the increase land using in flood plains area in Sleman district as a reason of cheap land. From various studies that have been done, which flooding occurs in areas prone basically due to three factors, namely: human activities, natural events and environmental degradation. This study aims to direct the management of flood plains area better. This research was conducted by exploration to find using river bank and evaluate policy and control mechanisms in the areas of space utilization riverbanks in Sleman district. the case study of river are: Boyong-Code river, Winongo river, and Gadjah Wong river. Generally, the drainage concept of the three rivers are still referring to the concept of conventional drainage. The concept was interpreted as a run off water as soon as possible to the river and further downstream. Even the conventional drainage is often interpreted as an effort to drying area. The concept must be changed with the concept of environmentally friendly toward the drainage, for example run off water into a river naturally. It is therefore necessary to overcome the floods with the application of the concept: "one river one plan and one integrated management".: Kabupaten Sleman merupakan lahan bagus untuk investasi lahan, mengakibatkan harga tanah di daerah tersebut semakin tinggi, sehingga masyarakat semakin mengincar daerah tersebut, akhirnya mempengaruhi peningkatan pemanfaatan lahan di daerah bantaran sungai di Kabupaten Sleman dengan alasan lahannya murah. Dari berbagai kajian yang telah dilakukan, banjir yang terjadi di daerah-daerah rawan banjir pada dasarnya disebabkan oleh tiga hal, yaitu: kegiatan manusia, peristiwa alam dan degradasi lingkungan. Penelitian ini bertujuan untuk mengarahkan pengelolaan lahan bangunan di daerah bantaran sungai untuk menjadi lebih baik.Penelitian dilakukan  dengan eksplorasi untuk menemukan profil pemanfaatan ruang bantaran sungai dan mengevaluasi kebijakan serta mekanisme pengendalian pemanfaatan ruang oleh bangunan di daerah bantaran sungai di Kabupaten Sleman. Sungai yang menjadi studi kasus ini adalah: sungai Boyong-Code, sungai Winongo, dan Sungai Gadjah Wong. Pada umumnya konsep drainase di ketiga sungai tersebut masih mengacu pada konsep drainase konvensional. Konsep tersebut mengartikan drainasi sebagai upaya mengatuskan air secepat-cepatnya ke sungai dan selanjutnya ke hilir. Bahkan drainase konvensional sering diartikan sebagai upaya pengeringan kawasan. Konsep tersebut harus diubah dengan konsep menuju drainasi ramah lingkungan, yaitu upaya mengalirkan air kelebihan di suatu kawasan dengan jalan meresapkan air atau mengalirkan secara alamiah dan bertahap ke sungai. Oleh karena itu perlu penerapan mengatasi banjir dengan konsep: “one river one plan and one integrated management”.

Abstract

This paper investigated how much the public's willingness to pay (WTP) for the cost of public water supply services (PDAM) in Pekanbaru City. This research also projected how much urban water demand of this city for period of 2014-2032. This study divided samples into two categories, namely (i) middle and high income society, and (ii) low income one. These categories were based on the type of house ownership, and the percentage of low income family in this city This research obtained two main factors affected to the WTP for public water services (Y), such as; (i) the number of family members (X1), and (ii) the amount of family income (X2). The equation formula of Y = -677.816 + 12934.502 X1 + 0.012 X2. The average public’s willingness to connect to PDAM for the middle and high income society was 62.13% and for the lower class was 44.44%.There was a trend that the middle and high incomes society’s water demand was relatively higher than that the lower one.  The amount of water tariffs for middle and high income class society was at the average of Rp.6.615 / m3, and Rp.4.971/m3 for the lower income one. This tariff was higher than the average tariff in 2014 (Rp. 3,300 / m3). The water supply capacity in 2014 was estimated to 620 l/sec, and it was projected that water demand in 2032 will increase to 3,946 l/sec (three folds). Tulisan ini meneliti berapa besar keinginan masyarakat untuk membayar biaya pelayanan pengadaan air bersih (PDAM) di Kota Pekanbaru dan membuat proyeksi kebutuhan air bersih Kota Pekanbaru 2014-2032. Sampel calon pelanggan air bersih dalam penelitian ini dibagi atas dua kategori, yaitu (i) masyarakat kelas menengah keatas, dan (ii) kelas menengah kebawah. Penelitian ini mengidentifikasi dua faktor utama yang mepengaruhi keinginan masyarakat menengah ke atas membayar pelayanan air bersih PDAM (Y), yaitu; (i) jumlah anggota keluarga (X1), dan (ii) besarnya pendapatan keluarga (X2), dengan formula Y= -677,816 + 12934,502 X1 + 0,012 X2. Keinginan untuk menyambung pada masyarakat menengah keatas sebesar 62,13% dan di kelas menengah kebawah adalah 44,44%. Besarnya tarif air bersih yang diinginkan masyarakat menengah keatas Rp.6.615/m3 dan Rp.4.971/m3 untuk kelas menengah kebawah.Tarif ini lebih tinggi dari rata-rata tarif PDAM pada tahun 2014 yaitu Rp. 3.300/m3.Kapasitas pasokan PDAM air pada tahun 2014 adalah 620 l/detik, namun diproyeksikan kebutuhan air bersih meningkat menjadi 3.946 ll / detik untuk tahun 2032.

Abstract

The growing number of private transportation ownership from year to year creates congestion problems, especially in urban areas. Public transportation conditions such as the Rapid Transit Bus (BRT) are an alternative way to use transportation. BRT Trans Semarang Corridor 1 is the busiest public transportation route in Semarang City that stretches from Mangkang Terminal to Penggaron Terminal. About 50% of the passengers of BRT Trans Semarang Corridor 1 chose to walk to and from the bus stops. However, in reality, currently, the conditions of the pedestrian paths are less than optimal in creating pedestrian comfort, and the integration system is still minimal with various modes. The purpose of this study is to identify a travel demand model suitable for pedestrian BRT Trans Semarang Corridor 1 passenger using the new urbanism 3D approach (Density, Diversity, Design). Where the data collection for analysis needs using naturalistic observation techniques by looking at the condition of the object of research in a more real way directly to the field. Density analysis used descriptive statistical analysis methods and simulated interpolation of population and building density data using the ArcGIS 10.3 application to generate pedestrian demand for their environmental density. In analyzing diversity using the land-use distribution simulation method with ArcGIS 10.3 and FAR (Floor Area Ratio) analysis using the 2016 Sketchup simulation. Compile a pedestrian path model recommendation under pedestrian demand.

Abstract

Suspended load transported by irrigation water should be inhibited to enter irrigation channels and farms due to its effects on channel and land aggradations. Current sediment traps are perceived to be costly in land requirement and construction cost. This research is intended to obtain an optimum length: width ratio for sediment traps, in order to minimize land requirement by extending their length without extra land. Experiment was conducted by introducing 1, 3, 5, and 7 cross baffles, and 0, 1, 2, and 3 elongated baffles into the model with 5 discharge for each configuration. From the experiment, it was found that the optimum sedimentation was gained by introducing 5 cross baffles into the current model, since the increment in discharge does not significantly increase sediment outcome.Muatan sedimen layang yang terbawa oleh air irigasi harus dicegah memasuki jaringan irigasi dan lahan karena dampaknya yang merugikan terhadap pendangkalan saluran dan peninggian lahan. Kantong lumpur yang dipakai saat ini dirasakan tidak efisien dalam hal biaya dan lahan. Penelitian ini dimaksudkan untuk memperoleh perbandingan panjang:lebar yang ideal untuk kantong lumpur, untuk meminimalkan kebutuhan lahan dengan cara meningkatkan panjangnya tanpa menambah luas lahan. Penelitian dilakukan dengan menambahkan 1, 3, 5, dan 7 sekat arah melintang,dan 1, 2, dan 3 sekat arah memanjang, dengan perlakuan 5 debit untuk masing-masing sekat. Dari penelitian ini disimpulkan bahwa pengendapan sedimen yang optimum diperoleh dengan 5 sekat melintang, dimana peningkatan debit tidak meningkatkan persentase sedimen yang lolos melalui sekat secara signifikan.
