Abstract

Bumi Serpong Damai (BSD) is one of self contained city in Jabodetabek district. Sinarmas as developer of BSD started to develope the Mass Rapid Transit which special operated on that. Concept of MRT has been operated in the form of Bus Rapid Transit. A new BRT corridor implementation need a Passenger Demand Prediction . Thus, a special BRT Passenger Demand Modelling Method for a new BRT Line need to be developed. This attempt needs knowledge on the Existing BRT User Trip Characteristics. BSD Link User Trip Characteristics Survey were executed on Corridor Sector 1.3 Greenwich Park, during morning peak hour. The result indicates that the BRT are used mainly for working (63%) and schooling (37%) trips, the BRT passengers are the previous public transport (45%) and motorcycle (55%) users. The trip origin zone is extended 1 km to the left and right of the BSD Link corridor, while the trip destination zone is extended 500 meters to the left and right of the BSD Link corridor. The embarking connecting trip modes are dominated by motorcycle (43%) and walking trip (57%), while the alighting connecting trip modes are dominated by motorcycle (16%) and walking trip (84%)

Abstract

Tanah lempung lunak adalah jenis tanah lempung yang memiliki nilai CBR rendah dan swelling yang besar, selain itu bahan organik dalam tanah lempung tersebut harus menjadi bahan pertimbangan, karena jika melewati batas maksimum akan mereduksi kekuatan dan stabilitas dari proses stabilisasinya. Tujuan penelitian ini untuk mengetahui pengaruh penambahan abu vulkanik dan semen Portland terhadap kekuatan dan stabilitas tanah lempung organik artifisial serta tebal perkerasan rencana yang digunakan. Tahap perlakuan awal, tanah lempung lunak dicampur dengan 3 variasi kadar abu vulkanik, kemudian diperam selama 3 hari. Tahap perlakuan akhir, tanah hasil campuran ditambahkan 5% semen Portland, lalu kembali diperam selama 3 hari. Pengujian sifat fisis meliputi  spesifik gravity, batas cair, batas plastis. Specific gravity meningkat dari 2,58 menjadi 2,65, batas cair menurun dari 71,48% menjadi 43,45%, batas plastis meningkat dari 28,96% menjadi 34,08%, indeks plastisitas menurun dari 42,52% menjadi 9,37%. Pengujian sifat mekanis meliputi pemadatan, CBR, dan pengujian swelling. OMC mengalami penurunan dari 33,696% menjadi 29,586%,  MDD mengalami peningkatan dari 1,319% menjadi 1,351%, CBR mengalami peningkatan dari 2,87% menjadi 9,77%, dan swelling mengalami penurunan dari 2,36% menjadi 0,45%, serta tebal perkerasan rencana berkurang dari 15 cm menjadi 8 cm untuk campuran tanah lempung organik dengan 15% abu vulkanik dan 5% semen.

Abstract

Traffic congestion in Ciputat area due to increasing of trip generation unsupported by transportation facilities and adequate road network. Generally, solution that implemented is road network capacity upgrades with widening based on trip generation analysis. The purpose of this research to determine trip generation model, total of trip generation, factors that influence of trip generation, and characteristics of trip users on Sawah Baru residence Ciputat Tangerang Selatan. The research method used by household interview survey about number of family members, amount of income per month, number of people working, number of students, number of vehicle owners, amount of transportation costs per month, also trip data from family members daily. Data that has been collected then analyzed with multiple linear regression method used SPSS 25.0 application with significant level 95%. Trip generation model of Sawah Baru residence can be attained Y = 0,450 +0,833 X1 with R2(R square) = 0,833. Total of trip generation that is generated by Sawah Baru residence = 333 trip/day. Based on t Test with significant level <0,05, therefore an influential factors are number of family members, amount of family income, number of people working, number of students, vehicle owners, and transportation cost.

Abstract

Activity in schools area located in the Suradita Village area has the potential to cause traffic congestion because the schools start time coincides with the rush hour for work. This is due to the fact that the schools do not have a designated area for dropping off passengers, which forces vehicles transporting students to stop or park on the road, reducing the road’s capacity. The purpose of this research to determine trip attraction model, totals of trip attraction, factors that influence of trip attraction, and trip rate on SDN Rahayu, SDN Suradita, MIS Nurul Falah area. The research method used is interview to students, teachers, and staffs about trip data, also secondary data collection were amount of students, teachers, and staffs, land area, floor space, amount of classrooms, parking area of SDN Rahayu, SDN Suradita, MIS Nurul Falah area. Data that has been collected then analyzed with multiple linear regression method used SPSS 25.0 application with significant level 95%. Trip attraction model of SDN Rahayu, Suradita, and MIS Nurul Falah can be attained YSMDS = 0,998 + 0,199 JS + 0,067 JGK – 0,071 JRK with R2 (R square) = 0,636. Total of trip attraction that is generated by SDN Rahayu, SDN Suradita, MIS Nurul Falah area = 463 trip attraction/day. Based on t Test with significant level <0,05, therefore an influential factors are amount of students, teachers, and staffs, also amount of classrooms. Trip rate of SDN Rahayu, SDN Suradita, and MIS Nurul Falah = 0,9 people/m2 or 9 people/100m2.
