Abstract

The public spaces in essence should be able to accommodate the users. Especially with users who have special needs or called user inclusive. One thing that is often overlooked in the application of the space design is elderly. Though the government launched the Elderly Friendly Cities program and one of them is the most populous Semarang in Central Java, 34 percent of the total population. Poncol Station Semarang is an example of public service that is not fully provide even distribution in terms of design. In fact, Poncol station offers ticket price reduction if the purchase is done directly at the station counter by twenty percent of the original price of special elderly where their activities should be contained fully included in the design space that is enterance Pre-Area, parking and drop-off, and the building area is the lounge, counters, toilets and platforms. Therefore, the question arises of research "Any element of design in the public service Poncol stations required for the creation of inclusiveness for the elderly with limited balance?". Therefore, the purpose of this study is to formulate needs space design elements inclusive public services for the elderly in Poncol Station. Using quantitative research methods to obtain a picture of the elderly activity conducted in each room at Station Poncol and needs in order to create design elements inclusivity using quantitative descriptive techniques. The results of this study found a tendency for the needs of design elements and limitations.

Abstract

The development of a city usually is accompanied by traffic congestion and air pollution problems. The appropriate strategy to solve these problems has been debated for long time. The proponents of new urbanism believe that the problem can be improved by forcing more people and more cars into smaller areas . They assume that by forcing densities higher, public transit can be provided better and more efficient, so that people will be more inclined to abandon their automobiles and use public transit, bicycles or walking as an alternative. On the contrary, anti-urban traditions believe that densifying urban areas will only worsen traffic congestion, and in turn will worsen air pollution. So that the best approach to solving the problem would to let urban sprawl, to dispersetraffic and to make it move faster. This paper describes both approaches and the impacts, and discuses which one is the best from Indonesian perspective.Keywords: urban density, urban sprawl, new urbanism, smart growthPerkembangan kota biasanya dibarengi dengan masalah kemacetan lalu-lintas dan polusi udara. Strategi apa yang harus ditempuh untuk mengatasi hal tersebut merupakan perdebatan yang panjang. Para pendukung new urbanism percaya bahwa kemacetan dan polusi bisa ditanggulangi dengan memaksakan lebih banyak orang dan kendaraan dalam kawasan yang sempit. Dengan lebih terkonsentrasi, penyediaan angkutan umum bisa lebih baik dan efisien, sehingga orang akan mengurangi penggunaan kendaraan pribadi  dan cenderung menggunakan angkuatan umum, bersepeda atau berjalan kaki. Sebaliknya budaya suburban dengan gagasan urban sprawl menganggap bahwa kemacetan disebabkan karena terlalu banyaknya kendaraan di wilayah yang sempit, dan pada gilirannya kemacetan memperparah polusi. Oleh karena itu kota harus dibiarkan berkembang menyebar, untuk menyebar lalu-lintas. Tulisan ini membahas kedua pandangan tentang kepadatan kota, dampaknya, serta mengkajinya dalam perperktif geografis dandemografis, yang manakah yang terbaik untuk Indonesia.Kata Kunci: kepadatan kota, pemekaran kota, new urbanism, pertumbuhan cerdas

Abstract

The characteristics of the mixture with the heat of hydration of cement type I in the new field reads the peak temperature, the temperature of which is formed after a period of Dormant (Dormant Period) in the hydration process. The temperature difference between the core and the upper part in several monitoring results exceed 20oC thermocouple can be a trigger cracks in the long run. Overall the presence of fly ash in the concrete mix in the field is not indicated on the temperature recorded. Use of Type II cement and fly ash on the large size of the test specimen in the laboratory have not been able to lower the temperature of the mixture to the maximum, whereas for the test object with the smaller size of the maximum temperature can be met. While the temperature characteristics of the setting time with a standard test specimen (100mm x 100mm x 100mm) is not easy to be a reference to the behavior of the temperature setting time of concrete with large volume. Visually, the condition of the specimen without micro cracks, thus assuming that was taken is that the difference in temperature of the test element with the top of the core temperature is not too large (<20 ° C). Such assumptions can be said is correct. With the lack of density, the temperature difference between the core layer and the top layer will not be large, because of the greater porisitas, seen from the test results PUNDIT, fast propagation rate only shows the value of 3.7 km / sec. Correlation of field test data with the data observed in the laboratory basically can not be done, because different forming materials. But the future by using cement concrete type I and fly ash by 15%, recorded temperature reaches the temperature limit (85 ° C) which can cause very large voltage difference in the concrete. The use of fly ash in greater amounts and type II cement in the test specimen in the laboratory, showing the recorded temperature reaches 68oC temperature limit, the value is lower by 19% of the maximum temperature in the field.Karakteristik panas hidrasi campuran dengan semen type I di lapangan baru terbaca pada suhu puncak, yaitu suhu yang terbentuk setelah periode Dormant (Dormant Periode) dalam proses hidrasi. Perbedaan suhu antara bagian inti dan bagian atas pada beberapa hasil monitoring thermocouple melebihi 20oC dapat menjadi pemicu retak dalam jangka panjang. Secara keseluruhan adanya fly ash dalam campuran beton di lapangan tidak terindikasi dari suhu yang tercatat. Pemakaian semen type II serta fly ash pada benda uji ukuran besar di laboratorium belum dapat menurunkan suhu campuran secara maksimal, sedangkan untuk benda uji dengan ukuran lebih kecil suhu maksimum tersebut dapat dipenuhi. Sedangkan karakteristik suhu pada setting time dengan benda uji standar (100mm x 100mm x 100mm) tidak mudah dijadikan referensi untuk perilaku suhu setting time beton dengan volume besar. Secara visual, kondisi benda uji tanpa retak mikro, dengan demikian asumsi yang kemudian diambil adalah bahwa perbedaan suhu elemen uji bagian atas dengan suhu inti tidak terlalu besar ( < 20 °C). Asumsi tersebut dapat dikatakan sudah benar. Dengan kurangnya kepadatan, maka perbedaan suhu antara lapisan inti dan lapisan atas tidak akan besar, karena adanya porisitas yang lebih besar, terlihat dari hasil uji PUNDIT, nilai cepat rambat gelombang hanya menunjukkan nilai 3.7 Km/sec. Korelasi data hasil pengujian di lapangan dengan data hasil pengamatan di laboratorium pada dasarnya tidak bisa dilakukan, karena bahan pembentuk berbeda. Tetapi beton masa dengan menggunakan semen type I dan fly ash sebesar 15%, suhu terekam mencapai suhu batas (85°C) yang dapat menyebabkan perbedaan tegangan sangat besar dalam beton. Pemakaian fly ash dalam jumlah lebih banyak serta semen type II pada benda uji di laboratorium, menunjukkan suhu terekam mencapai suhu batas 68oC, nilai tersebut lebih rendah sebesar 19% dari suhu maksimum di lapangan.

Abstract

The position of the city of Semarang reviewed in national and regional strategic growth will have an impact that is local traffic as well as being large enough. Growth substantial traffic generating traffic flow should be assessed continuously so as not to cause a negative impact. Traffic flow is large enough without setting the appropriate traffic pattern would cause long delays and queues were quite long. Traffic patterns of a road we can see from the pattern setting which is at the intersection of the segment. The parameters studied include the number of vehicles coming out of each arm, current conditions and time of the signal. This analysis includes: basic saturation flow, traffic flow, cycle time, green time, capacity, degree of saturation and traffic behavior. Rated capacity of the intersection for the morning peak period in Simpang Kuhl has a value of 2171 pcu/hour to approach the direction of the straight east. Of the value of the degree of saturation at each approach that most had values> 0.800; especially in the morning to the east to the west and the evening to the west to the east. In the morning peak period the average intersection delay that occurred at 42.80 seconds/pcu. At peak times during the intersection delay by an average of 55.10 seconds/pcu. In the afternoon peak period with an average intersection delay of 45.47 seconds/pcu.Posisi kota Semarang ditinjau dalam skala nasional maupun regional sangat strategis akan menimbulkan dampak pertumbuhan lalu lintas yang bersifat lokal maupun menerus yang cukup besar. Pertumbuhan lalu lintas yang cukup besar menghasilkan arus lalu lintas yang harus dikaji terus menerus sehingga tidak menimbulkan dampak negatif. Arus lalu lintas yang cukup besar tanpa disertai pengaturan pola lalu lintas yang sesuai akan menyebabkan tundaan yang cukup lama dan antrian yang cukup panjang. Pola arus lalu lintas suatu ruas jalan dapat kita lihat dari pola pengaturan simpang yang berada pada ruas tersebut. Parameter yang diteliti meliputi jumlah kendaraan yang keluar dari masing-masing lengan, kondisi saat ini dan waktu sinyalnya. Analisis ini meliputi : arus jenuh dasar, arus lalu lintas, waktu siklus, waktu hijau, kapasitas, derajat kejenuhan dan perilaku lalu lintas. Nilai kapasitas simpang untuk waktu puncak pagi di Simpang Bangkong memiliki nilai sebesar 2171 smp/jam untuk pendekat timur arah pergerakan lurus. Dari nilai derajat kejenuhan pada masing-masing pendekat yang sebagian besar memiliki nilai > 0,800; terutama pada waktu pagi untuk arah timur ke barat dan waktu sore untuk arah barat ke timur. Pada waktu puncak pagi tundaan rata-rata simpang yang terjadi sebesar 42,80 detik/smp. Pada waktu puncak siang dengan tundaan simpang rata-rata sebesar 55,10 detik/smp. Pada waktu puncak sore dengan tundaan rata-rata simpang sebesar 45,47 detik/smp.

Abstract

The economic growth in Semarang has resulted in bad impact of degradation the environment, traffic jams, increasing informal sectors and unemployment, crimes, and various social-politic conflicts. From this phenomenon, it is suspected that Semarang is undergoing overurbanization, that is the imbalance between population and economic growth.           From the result of research, it can be concluded that the main determinant of urbanization process in Semarang is the prolonged capitalization from colonial era. However, it not industrialization that develops, but informal sectors and service sectors. The impact is the city involution because as if the new employees can never participate in informal sectors. As a result, the Semarang City Government must mobilize non-producing resources to finance creating and organizing the needed service for high concentration of population under low standard of industrialization. In other words, Semarang and the hinterland are indeed undergoing “de-industrialization”. Industrial and agricultural sectors decreases their role, and on the other hand the service sector increases. In those areas, urbanization tends to occur with a spreading pattern characterized by high rate of population in urban areas like in regencies surrounding Semarang. The economic growth in those areas does not depend on the core city, Semarang, so that the level of advanced primate city has been passed through. The suggestions proposed are that the megapolitan issues has been reached, thus the things that need to consider in megaregional tendency. The regencies in the hinterland are proven “to balance’ the global capitalism, apart from wether the growth of enterpreunership innovation is accompanied by significant increase of welfare. This means that things need further attention is to manage the relationship between locality and production system and global economic in those ares to make people welfare and prevent people to migrate to other big cities.
