Abstract

This research is to study the periodic and stochastic models in the series of daily rainfall data. The study was conducted using daily rainfall data with a data length of 25 years (1977-2001) from the station of Banjar Agung, Gisting and Gunung Batu. This research used secondary rainfall data from Tanggamus, This study change the series of daily rainfall data into the sepektrum rainfall using FFT (Fast Fourier Transform). Periodicity of daily rainfall data were presented by using 512 rainfall. Stochastic series of rainfall data are assumed as the difference (error) between the rainfall data with periodic rainfall model. Results of this study is the correlation coefficient from three rainfall stations In this study, the correlation coefficient (R) between the data and the periodic model is 0,9974, between stochastic data series and stochastic models is 0,9996, and between data and periodic stochastic models is 0,99997. From these results it can be concluded that the periodic stochastic models of rainfall from Tanggamus periodic models using 512 rainfall data, the approach provides a very significant.

Abstract

This research aim to identify and analyze the sectors that are the basis of each district for the de- velopment of the Subdistrict. Determining and describing the potential competitive sector of each sub has the greatest potential to contribute to the economic development of Newburn and condi- tions of the road network that will support the regional development of Fortuna. Of each District in Newburn shows the different basis, mainly due to the Subdistrict area devel - oped into the urban industrial sector emerged as the basis in some districts. The road network is not well with the condition and do not meet the standard of the existing road. With the develop- ment of the Subdistrict for Trade and Services are necessary to be an increase in the road, espe- cially the relationship between the center - a center of the preferred road network of collectors.

Abstract

Road is one of many things that support the development of construction at citties and villages. Not every soil can be directly used for road construction. Soil conditions in one area will not have the same soil properties with the other area. Some has a good bearing capacity and there’s also some with poor soil bearing capacity. This thing is very influenced by the type of the soil, so that on constructionis is requred a deeper understanding of the soil behavior analytically. In this research, the tested soil is study clay soil that diviced from Dusun kali ayu, Desa jadti baru, Kecamatan tanjung bintang, Kabupaten Lampung Selatan-Provinsi Lampung had been optimized with TX-300 with density of 2.49, water contents of 22.34 percent, 41.08 percent Liquit Limit, plastic limit of 31.92 percent and plasticity index of 9.15 percent. Mixed content of TX-300 that used was 1.2 ml and 6 kg soil sample for 0,7,14 and 28 day with unsoaked method. On physical examination like density and liquit limit increased after stabilized. While the mechanical examination, TX-300 is quite effective in increasing the bearing capacity along with the increasing of curing duration from 21.69% up to 25.92% in 28 days curing time. From CBR test result without soaking , the soil that has stabilized with TX-300 has a less effect in increasing the bearing capacity of the sandy clay soil compared with of stabilizing on soft clay soil.

Abstract

Dalam penataan kawasan perkotaan, khususnya penataan koridor jalan, survei visual menjadi salah satu metode yang signifikan yang dapat memberikan persepsi dan data empiris kawasan yang berguna dalam pemecahan masalah perancangan. Salah satu metode dalam melakukan survei dan sekaligus analisis ruang perkotaan adalah dengan pengamatan terhadap aspek spatial enclosure ruang jalan. Spatial enclosure adalah tingkatan atau derajat ketertutupan ruang yang memberikan kesan dan persepsi psikologis terhadap pengamat. Persepsi psikologis ini berbeda- beda, tergantung pada proporsi dan skala ruang yang terbentuk berdasarkan perbandingan an- tara jarak elemen vertikal dan ketinggian elemen vertikalnya. Melalui survei visual terhadap proporsi dan skala ruang jalan, maka dapat diketahui tingkat ketertutupan ruang suatu jalan yang menjadi dasar dalam analisis dan perencanaan ruang jalan. Proporsi diketahui dengan mengukur ketinggian pelingkup vertikal (dinding/h) terhadap jarak datar (lantai/tanah/d) yang dibentuk oleh elemen keras (hardscape) maupun lunak (softscape). Penelitian ini bertujuan untuk mengetahui spatial enclosure pada koridor jalan di kawasan perda- gangan Teluk Betung melalui analisis rancangan yang terbentuk. Hasil penelitian menunjukkan bahwa rancangan ruang jalan di area studi terdiri atas main enclosure dan secondary enclosure. Main enclosure memberikan efek psikologis dalam konteks skala kawasan dan kota, sementara secondary enclosure memberikan efek psikologis pada tingkat kawasan dan mikro. Penataan lebih rinci pada area secondary enclosure dapat menjadi kunci dalam melunakkan efek psikologis ru- ang yang ditimbulkan dan menciptakan ruang koridor yang berkarakter.
